The invention relates to agriculture and is aimed at improving the quality of irrigation and more efficient use of energy and irrigation water through the coordinated regulation of the speed of movement of the support trucks and make water under irrigation rate with precise watering.

Known multisupport sprinkling machine (A.S. NO. 1335201, A01G 25/09), including sprinklers installed on the pipeline machine, a base truck with actuator and limit switches are connected to the blocks to stabilize the machine in the line, the machine is equipped with included between the pipe and sprinklers electrically-controlled valves are divided into groups according to the number of limit switches and are connected in parallel to the stabilization unit of the machine in line with Elektroprivreda valves in each group is installed on the pipeline of the machine is symmetrical anchor trolley cars.

The disadvantages of this device is the following.

Irrigation through sprinkler (sprinkler nozzles)adjacent to the anchor trolley is made only when driving the support truck.

At a constant transfer rate of the drive support trucks and a constant value of the supply voltage of the actuator anchor trolleys layer of rain in a single pass is constant and does not depend on the setpoint soon the ti movement. There is no regulation made irrigation sprinkler machine.

As power plants use diesel internal combustion engine (AM-ND), which has a low energy efficiency (0,35-0,38) and pollute the environment by exhaust emissions. During the irrigation season the flow of diesel fuel per day up to 500 kg

After execution of the power and process of watering is not possible to determine the irrigation area during operation of the machine, for example, during a shift, the actual rate of irrigation and consumption of diesel fuel and, consequently, the energy intensity of the irrigation unit irrigation area.

Not regulated by the pressure in the pipeline, for example, stops short of supporting trucks electrically-controlled valves are triggered, which leads to the termination of the flow of irrigation water through the sprinklers and the change of the flow and pressure of the irrigation water in the pipeline. This leads to a significant change of pressure at the inputs of operating sprinklers, which leads to a change in the structure of rain clouds (the diameter of the drops will change). The use of this device is not energy efficient - is unreasonable consumption of diesel fuel.

A device for automated control multisupport front sprinkler mA is different (A.S. No. 1391544, A01G 25/09), including installed on trucks with electric drive, the left and right wings of the machine, the synchronization unit movement at the rate of the guide wire and the control unit speed machines installed at the entrances to the pipeline right and left wings of the valves with electric drive, with hinged switch with anchor roller and sensors absorbency of the soil and referencing norms of irrigation irrigated right and left wings of the machine fields.

The disadvantage of this device is the following.

Unreliable electrical contact field and the receiving switch and the power supply to the sensors status absorbency of the soil.

The analyzer determines the average value of the readings of all sensors absorbency under each of the wings of the machine. Averaging sensors will lead to inaccurate job of irrigation under the appropriate wing.

Regulation of the flow of irrigation water through a throttling hydrosulfite degrades the quality of the rain clouds. Sprinkler nozzles, which are evenly placed along the entire length of the pipeline should be at the entrance constant pressure. By reducing the pressure of the irrigation water in the pipeline as the rain clouds deteriorating due to the enlargement of the diameters of the droplets, which negatively affects the physico-m the mechanical characteristics of the soil (utrambovyvanie soil blows big drops of rain).

There is no operational monitoring and controlling the speed of movement of the machine and, therefore, the norm of irrigation, irrigation water discharge, definition of distance traveled by the machine, the length of time of operation of the machine.

There is no possibility after the passage of the machine irrigated area of the field to determine the fuel consumption, is a layer of rain (the actual value of irrigation), irrigation area and the total value of running time and the total is made of the actual amount of water applied (irrigation rate) and, therefore, the energy intensity of the irrigation unit area.

Not regulated by the pressure in the pipeline, for example, stops short of supporting trucks electrically-controlled valves are triggered, which leads to the termination of the flow of irrigation water through the sprinklers and the change of the flow and pressure of the irrigation water in the pipeline. This leads to a significant change of pressure at the inputs of operating sprinklers, which leads to a change in the structure of rain clouds (the diameter of the drops will change). The use of this device is not energy efficient - motor efficiency of internal grania is 0.35. And pollution by emissions of combustion products.

A01G 25/09.).

The disadvantages of this device is the following.

There is no possibility to control the quality of execution of the power and process of watering directly under irrigation.

Quickly in energy technological process of irrigation are not indicators of the efficiency of irrigation.

There is no possibility to provide different values of irrigation norms for different size areas of irrigation (under each of the wings of the machine, parts of sowing different crops).

There is no possibility of visualization of the operational indicators of the efficiency of irrigation.

There is no possibility of measuring soil moisture in irrigated area of the field, as before watering, and after watering.

The objective of the invention is improving the quality of irrigation, the reduction in the energy intensity of the process and more environmentally friendly energy technological process precise watering and irrigation water saving.

Since the end of XX century in the practice of agriculture in developed countries apply information-rich methods, technologies and techniques to improve the efficiency of production.

In crop production, this doctrine is implemented in the form of the concept of precision farming. The traditional technology of fertilizer in the average dose to the whole area of the field without taking into account nutriology variability parameters of soil fertility do not provide the specified payback fertilizers, realization of the genetic potential of crops.

Precision agriculture (ang. Precision Agriculture is a new popular concept of production. Precision agriculture can be defined as a holistic system designed to optimize agricultural production through the use of information on the cultures of advanced technologies and methods.

Under the General name of "Precision Agriculture" includes the following:

- organization of production at the level of elementary plot (fertilizer, nitrogen fertilization, tillage, irrigation, planting, application of fertilizers, herbicides and growth regulators);

- automation of production processes (automatic system for parallel driving control over the technical condition of machinery and other);

- logging, monitoring, recordkeeping (measurement fields, accounting, productivity, time tracking and energy).

A comprehensive approach to precision farming starts with the planning of agricultural production and includes the handling, planting, watering, application of chemicals, harvesting and post-harvest tillage. When working with this method of production must be considered agricultural fields are not as one, and be divided into sections and take into account the difference of soil and diversity of the crop in the same field.

Enhan is in precision farming is the following:

the farmer saves the quantity of fertilizer where there is enough nutrients in the soil, and increases the dose where there is a need for them. This will be the increase in yield with a minimum consumption of mineral fertilizers;

the farmer saves the quantity of irrigation water where soil moisture is sufficient, and increases the rate of irrigation where there is a need for them. This will be the increase in yield at the minimum expense of irrigation water;

- energy savings to make in the irrigated area of the field of irrigation water and diesel fuel;

accurate irrigation sprinkler becomes energy saving;

- no education areas of over-watering and neopolia that leads to waterlogging islets field and foregone harvest from over-watering, and from neopolia, improve the environment, protection of soil and groundwater.

Figure 1 shows a functional diagram of the device of the automated control multisupport sprinkling machine front steps for precise watering,

Figure 2 shows the structural diagram of the device, Figure 3 shows a functional diagram of the transmission of signals from moisture meters via satellite on sprinkler machine.

Device auto is titiraupenga management multisupport sprinkling machine front steps for precise irrigation consists of tubing 1 (length 787 m), mounted on the two outer leading anchor trolleys 2 and the intermediate support 3 trucks (for example, 16 pieces), which are A-shaped. Sprinkler nozzle 4 via the electrically-controlled valve 5 and pipe 6 is installed evenly along the length of the pipeline 1. Electrically-controlled valve 5 is designed to overlap the water flowing to the sprinkler nozzle 4 of the pipe 1 through the pipe 6. To control the movement of the intermediate support cart 3 installed devices synchronization trucks in line (PSL) 7, which generates a command for movement of the actuator 8, which is mechanically connected to the wheel 9. When the freewheel relative to the adjacent more valid intermediate anchor trolley 3 team PSL 7 stop, and when the lag is starting to move. The group of electrically controlled valves 5 sprinkler nozzles 4 that are adjacent on two sides to the intermediate anchor trolleys 3, are connected to the corresponding PSL 7 and, when the PDP 7 generates the command to stop the intermediate support 3 trucks, electrically-controlled valves 5 are included and block the water that comes through the sprinkler nozzles 4 in the field, and with the development team on the movement of electrically controlled valves 5 are disconnected and the water enters the sprinkler nozzle 4.

At the two extreme ends of the leading anchor trolleys 2 set the go devices stabilization course (PSC) 10, create a command to move at the leading anchor trolleys 2 depending on the deviation of the machine from the direction (lateral deviation). The group of electrically controlled valves 5 sprinkler nozzles 4 that are adjacent on two sides to the extreme leading anchor trolleys 2, are connected to the corresponding UCS 10 and, when the UCS 10 generates the command to stop at the leading anchor trolleys 2, the electrically-controlled valve 5 connected to the corresponding UCS 10 are also block the water that enters the box through the sprinkler nozzles 4, and with the development team on the movement of electrically controlled valves 5 are disconnected and the water enters the sprinkler nozzle 4. Algorithms movement at the leading anchor trolley 2 can be different, for example, in the correction of the extreme wheel supporting truck 2: stop (irrigation through sprinkler nozzles 4 stops), slow speed (watering is carried out through a portion of the sprinkler nozzles 4) or corrected at the leading anchor trolley 2 slows the movement speed and the other at the leading anchor trolley 2 increases the speed. The algorithm of operation of electrically controlled valve 5 and the flow through the sprinkler nozzles 4 that are adjacent to the extreme leading anchor trolley 2 can also be different (for example, p is a descent through the sprinkler nozzles 4, surrounding the extreme leading anchor trolleys must be greater than through the sprinkler nozzles 4 that are adjacent to the intermediate support trucks 3 (20-25%).

Extreme wheel supporting truck 2 are less constructive speed compared with the design of the intermediate support 3 trucks, which move in the "stop-start" mode. In the irrigated area of the field padded irrigation channel 11, where the intake device 12 by means of a pump 13 through the flow meter 14 and electrohydrostatic 15 delivers the water into the pipeline 1. The pressure gauge 16, which is installed in the pipe 1 has an electric outlet and is used to measure water pressure. The motor 17 is designed to drive the pump 13, which feeds water into the pipeline 1. The motor 17 is fed from the control Board (CB) 18, in which is placed a protective apparatus through the control panel (PU) 19. In PU 19 posted by microprocessor control unit (MBU)20, a counter electrical energy (SE) 21, the contactor (K) 22 and the timer 23. MBU 20 is designed to control the movement and process of irrigation, storage, recording the results and calculate the efficiency of the process of irrigation. SE 21 is designed to measure the consumption of electrical energy. Readings SE 21 is continuously supplied to the motors 20. The timer 23 is designed to synchronize the work MBU 20. The starting command To the 22 comes from MBO. The output 22 is connected to the motor 17. To 22 serves for switching the electric motor 17 with a frequency Converter (PE) 24. The signal from the MBU 20 arrives at the PE 24, which converts the (governing) voltage and frequency. Using PE 24 regulates the voltage and frequency supplied to the actuator 8 at the leading bogies 2 and intermediate 3 trucks, resulting governed by the speed of rotation of the actuator 8 and the rotation speed of the wheels 9 and, consequently, the speed of movement of the support trucks 2, 3. Also from PE 24 adjustable voltage supplied to the motor 17 through 22. To provide different irrigation norms is the unit of irrigation norms 25, and the unit length of the plot irrigation 26 sets the length of the plot irrigation (length of watering depends on the length of the plot planting crops), the outputs of which are connected with MBU 20. The signal to stop the machine States of the PDP 7 (emergency stop) is formed in the synchronization system of trucks in line 27. Stabilization of the rate of 28, which is installed over the guide wire 29 has a device stabilization course (UIC) 30, which is mounted on the intermediate support carriage 3, which is next to an irrigation canal 11, and generates a command corresponding to the correction at the leading anchor trolley , which is received in a corresponding PSC. In the extreme leading anchor trolley 2 with the flow path 31, which measure the actual distance traveled at the leading anchor trolleys 2 of the corresponding wing. For the transmission of information via communication channels (for example, the rate of irrigation, the irrigation area, time of irrigation and other) and set the tuning parameters used by the interface device 32, which is connected with MBU. Over the irrigation channel 11 on the intermediate support carriage 3, which is closer to the guide wire 29, mounted on a telescopic mechanism 33, the current collector 34. Telescopic mechanism 33 is used to compensate for lateral displacement of the intermediate trolley 3 from the contact network 35. The current collector contact 34 is connected with the contact network 35, which is available on the racks 36 along the irrigation channel 11. The casing 37, secured to the uprights 36, protects the contact network 34 from direct exposure to rain and serves as a protective barrier against accidental contact by the operator or a third party. The vacuum pump 38 is designed for water intake to the pump 13 through the intake device 12 of the irrigation channel 11. Irrigation water passing through the flow meter 14 and electrohydrostatic 15, enters the pipeline 1.

For every anchor trolleys 2 and 3 set control blocks watering 39, in which the regulation is : duty cycle signals. The outputs of the control unit irrigation 39, which are mounted on the extreme leading anchor trolleys 2, are connected to the inputs of the device stabilization course (PSC) 10. The outputs of the control unit irrigation 39, which are mounted on the intermediate support cart 3, are connected with inputs of the device synchronization trucks in line (PSL) 7. Inputs control blocks watering 39 are connected to the outputs of block signal analysis 40, the output of which is connected to the input of MBU 20, and the input unit of analysis signals 40 is connected with GLONASS receiver 41. One of the inputs GLONASS receiver 41 is connected to the MBU 20.

All sprinkler nozzles 4 are divided into groups depending on the number of support trucks 2 and 3 (18 groups sprinkler nozzles 4). For example, half of the sprinkler nasdaw 4, which are placed on the migration machine to the left and to the right of the trucks 2 and 3, create a group. Irrigated area of the field on the width of the pivot is divided into 18 plots the number of groups sprinkler nozzles 4. In the irrigated area of the field in each square are moisture meters 42, which measures soil moisture and transmits the measurement result on the GLONASS satellite 43. The average width of the rain band sprinkler nozzles 4 is about 45 meters (depends on the distance between the support carriages 2 and 3 (the lengths of the spans). The length of the irrigated area of the field depends on the annual load to daulnoy machines and crops. For example, if the annual load sprinkling machine irrigation area equal to 105 hectares, the length of the irrigated area of the field will be L=1250 meters. Irrigated area of the field is divided into squares. The number of squares of size 45*45 m in the direction of the pivot will be 28 pc. Hence, the total number of squares and the number of humidity sensors 42 (provided that in each square will be installed one moisture meter 42) will be 18*28=504 pieces In the direction of the length of the squares (rectangles) can be more than 45 m depending on the terrain irrigated area of the field. In this case, the number of humidity sensors 42 will be much less. At the request of the operator sprinkler or agronomist agriculture signal from the humidity sensors 42 through the GLONASS satellite 43 is supplied to GLONASS receiver 41 and further analysis block signals 40. Information indications of moisture meters 42 through the GLONASS satellite 43, GLONASS receiver 41 and the block signal analysis 40 arrives at MBU 20, which is connected to the input of the touch screen 44. On the touch screen 44 can be displayed map irrigation field indicating the minimum, maximum and average values of irrigation norms. Map of irrigation can be transferred from the GLONASS satellite 43 system controls 45.

From the system controls 45 through GLONASS satellite 43, GLONASS receiver 41 iblock analysis of signals 40 on MBU 20 may be filed by the team at the beginning of irrigation irrigated area of the field.

Information on soil moisture in the irrigated area of the field, for example, after a rainfall, before irrigation after irrigation can be obtained in the system controls 45.

The proposed device operates as follows.

The proposed device can operate with different control algorithms. For example, an automated, semi-automated and manual control algorithms for energy technology the process of irrigation.

1. Automated control algorithm. Depending on the actual soil moisture squares irrigated field, the signal from the respective humidity sensors 42 is transmitted to the GLONASS satellite 43, which in turn transmits the signal to the GLONASS receiver 41. Next, the signals are sent to the unit of analysis signals 40, which is determined by the minimum speed of movement of the sprinkler, which provides a maximum irrigation norm (the square in which the measured soil moisture lowest). In the squares, in which the soil moisture is above the minimum humidity values, the unit of analysis signals 40 commands to the appropriate control unit irrigation 39, which in turn, by changing the duty cycle of the signal to the electrically-controlled valve 5 through STGS 7 and the UCS 10 will change the flow through the sprinkler nozzles 4. The signal from block signal analysis 40 is also fed to MBU. The input of the touch screen 44 from MBU 20 receives the results of measurement of moisture meters 42 and is presented on the touch screen 44, for example, a map field indicating the amount of water applied for each square. When managing sprinkler nozzles 4 by adjusting the duty cycle of the signal opening and closing groups sprinkler nozzles can happen fluctuation of pressure of the irrigation water in the pipe 1, which negatively affects the quality of the rain and mode of operation of the pump 13. The duty cycle signal to control the electrically-controlled valve 5 groups sprinkler nozzles 4 is regulated by the duration of the activation time and duration of time off of electrically controlled valves 5 in the time interval, for example 10 seconds. When changing the water pressure in the pipe 1, the signal from the pressure gauge 16 and the flow meter 15, arrives at MBU 20, after a failover signal from MBU 20 team goes through PE 24 to the electric motor 17, thereby stabilizing the flow and pressure in the pipeline 1. With the approach of the relevant supporting trucks 2 and 3 to the next square of the irrigated field unit of analysis signals 42 specifies a different value signal to the control unit irrigation 38 of the respective supporting trucks 2 and 3, and thereby changes the duty cycle of the control signals of the group of sprinkler heads 4.

2. Semiautomated algorithm control the deposits. For example, when water recharge irrigation is no need for precise regulation of irrigation by squares. The operator using the unit irrigation 25 specifies the desired rate of irrigation. The signals from the humidity sensors 42 are not used or humidity sensors 42 can be removed from the irrigated area of the field.

3. Manual control algorithm. Depending on crop type and the lack of satellite communications (for example, when magnetic storms, preventive breaks and other) agronomist Adjuster irrigation 25 sets the irrigation norm and with the help of unit length field area 26 is defined length of the plot irrigation. When restoring a satellite communications or when watering a different area of the field agronomist can be set to any control algorithm.

Supply voltage (for example, 380 V, 50 Hz) is supplied via the collector 34 of the contact network of 35 on QU 18. Telescopic mechanism 33 connects the current collector 34 with the intermediate carriage 3, which compensates for the lateral deviation. From SO electrical energy is delivered through the cell 21 on PE 24 and contactor 22. Before working on the team MBU 20 electrohydrostatic 15 closes and provides power to the vacuum pump 38. After filling of the pump 13 (filling the water pump 13) MBU 20 turns off the vacuum pump 38 includes a motor 17 through the contactor 22 and the QCD which indicates electrohydrostatic 15. Irrigation water is supplied into the pipe 1, while the flow meter 14 measures the amount of water used for irrigation. The readings of the flow meter 14 and 15 gauge arrive at MBU 20. In the absence of alarm signals in MBU 20 from the synchronization systems of trucks in line 27 and stabilization systems course 28, MBU 20 generates a command on the UCS 10 of both wings and the movement at the leading bogies 2, with a speed, which is determined depending on the irrigation determined by referencing the irrigation 25, or according to the humidity sensors 42.

When the manual control algorithm, for example, Ref irrigation 25 and the unit length of the plot irrigation 26 depending on the type and phase of development of the crop is set to the normal irrigation, for example, irrigation with normal 300 m3/ha, and the length of the plot irrigation, for example, 250 m, depends on the length of sowing (planting acreage of different crops on this irrigated area of the field. In MBU 20 produces a command on PE 24. PE 24, by regulation, the anchor trolley 2 and 3 takes this voltage, at which the speed at the leading anchor trolleys 2 provides irrigation norm 300 m3/ha.

The algorithm of the signal processing moisture meters 42 on the unit of analysis signals 40 makes it possible to correct errors in the failure of the humidity sensors 42. The signal from the failed and the measurer of humidity 42 is replaced by the signal of the previous or next function moisture meter 42, that is, when no signal from any of the moisture meter 42 this square will be the norm irrigation equal to the previous irrigation norm of a square or an adjacent square.

On the PDP 7 both wings with MBU receives a supply voltage (for connection of the actuator 8 and the electrically-controlled valve 5). PSL 7 intermediate supporting trucks 3 when behind it relative to the two adjacent generates the command to activate the actuator 8, which causes the rotation of the wheel 9 intermediate anchor trolley 3. On the PDP 7 also receives a signal from the control unit irrigation 39.

The signals from the sensors path 31, which are mounted on the extreme leading reference 2 trucks arrive at MBU. When coasting intermediate trolleys 3 magnitude more valid with respect to the adjacent trucks of the PDP 7 connects the group of electrically controlled valves 5 in the network and the water coming from the pipe 1, will cease to flow through the nozzles 6 and the electrically-controlled valve 5 in the sprinkler nozzle 4.

SUBSTANCE: compound navigation method combines satellite and radar ranging navigation techniques based on ground-based beacons, wherein satellite signals are received both on-board the aircraft and at the row of ground-based beacons, including at ground-based beacons at the landing strip. The ground-based beacons constantly refine base coordinates, determine differential corrections to coordinates and differential corrections to pseudo-ranges, generate a packet of correcting information with said differential corrections, errors in determination thereof, calculated tropospheric refraction data and the refined base coordinates of the ground-based beacons. Based on a request from an aircraft, the ground-based beacon emits, through a distance measurement channel, a signal with correcting information which includes differential corrections only in form of differential corrections to coordinates. The aircraft calculates navigation parameters taking into account correcting information, performs compound data processing and continuous comparative estimation of errors. Upon reaching the aerodrome area and landing, if the error value according to the satellite technique is less, the mode of generating a sequence of request ranging signals of the row of ground-based beacons is switched to a mode for requesting only one ground-based beacon located at the landing strip, wherein on the aircraft, differential corrections in the correcting information are transmitted only in form of differential corrections to pseudo-ranges. Refined coordinates of the aircraft are calculated from the corrected pseudo-ranges.
