Control method and control irrigation installation and device for its implementation
(57) Abstract:Usage: in the agricultural industry, in particular in systems and control irrigation devices. The inventive method provides for preliminary calculations, scheduling irrigation in the form prescribed time cycles on and off installation of irrigation. Thus in each cycle are remembering the time of the beginning and end of the irrigation within a certain period of time, then rewrite in the portable unit for recording, display and processing by computer. The last known algorithms gives recommendations for changes in irrigation scheduling, wage irrigators on the basis of the degree of actual and specified schedule irrigation cycles, as well as about the changes in the schedule of routine maintenance. This method are using a specific electronic device with a portable recorder 2 installed on irrigation installation, storage in the process of watering the watering time and idle time of installation in accordance with the state of the sensor 1 process of irrigation. After a certain period of time information from registercom the panel is filled in with the date and time overwrite this information. After that conduct an operational view this information using the computer on the control unit determines the remaining time for recording by the Registrar uptime and downtime irrigation installation. For a given algorithm, the computer determines the date and actual irrigation scheduling, pay labor foreman, designate the date and type of maintenance work and other activities. To record information about the time of watering and dead-time unit is equipped with a memory unit 13 mounted in the block 10, and a RAM memory unit 7 is set in the register 7. Recording in the memory 7 are using timer 4-managed scheme 3 ban through the Assembly 5, the inverter 6 and the counter 8 cycles of irrigation. To pair overwrite the information from the Registrar 2 in block 10 through the connector equipped with the latest first and second triggers and the first counter 12 cycles of irrigation. To display stored in the memory 13 of the information on the indicator 27 is the third 18 and fourth 24 triggers, and the second circuit 21 or the fifth trigger 14, the imaging unit 22 of the pulses from the inverter 28, and the third 20 and fourth 26 counters. The synchronization unit 10, as in overwrite mode information from the register 2, and the display mode and the processing mode with the aid of the willow crops and is intended for automation of management processes and monitoring of irrigation installations of any type.The aim of the invention is to improve the quality and efficiency of the management and control of the watering process.In Fig. 1 presents a block diagram of a device for monitoring and control of irrigation installation; Fig.2 is a timing diagram of the operation of blocks and elements of the device.Control method and control irrigation system type "Volzhanka" and other is as follows.Before watering set mode (time schedule on and off installation) and the irrigation area, after which include irrigation equipment. In the process of irrigation on the electric contact pressure gauge or pressure switch with contact output control working pressure (her work) and, in case of exceeding or falling, automatically shut off irrigation technique. Largest political space is performed manually or by computer calculation of wages, maintenance and repair of irrigation equipment. During such operation of irrigation equipment inevitably the lack of control of watering time and the length of time each time you change mode, and the inevitable biased assessment of the quality of irrigation throughout the irrigated area, low accuracy and reliability of the assessment, significant odnonapravlennogo time and season, as well as the low productivity of workers, leading accounting work irrigators and the calculation of their wages.When watering, for example, by using positional machines type "Dnepr", "Volzhanka" is often a situation when in one position setting is longer than the specified time, produces a large irrigation norm. Payment of labour of the waterer is largest watered area. Then he to be able to irrigate a given area, in its sole discretion keeps the car less time at other positions. Irrigation rate for these positions is smaller. Watering uniformity throughout the area, in this case, will worsen when you save the total time of irrigation.When employing continuous machines of type "Frigate", "Kuban" in order to increase the performance of the operator in its sole discretion may also reduce the total watering time, reducing the amount of irrigation norms, while maintaining the uniformity of irrigation. In both cases, irrigation is deteriorating because of the subjective influence and the concealment of these situations.The absence of an objective accounting of working time and idle time of irrigation technology leads to the fact that the delay is maintenance and repair of irrigation equipment, is the introduction of routine maintenance, or to increase the volume of work performed while reducing a given period (usually will be carried out maintenance work). This is inefficient in both cases.The subjectivity of action in the management of irrigation throughout the irrigated area, subjective control, and determine the period of time between maintenance work in the maintenance, their subjective evaluation leads to decrease in the reliability of the quality of irrigation, irrigation uniformity, to the increase of error issued by the magnitude of irrigation norms throughout the area, reduce the accuracy of the whole technological process of irrigation. Thus, subjective manual accounting watered area, manual subjective and approximate time work irrigators leads to an increase of staff leading this into account.In the described method to eliminate the above disadvantages by using installed at the entrance of irrigation installation Registrar of record and, then, control the time of irrigation and the lack of it within a certain period of time (several irrigation cycles), copy and scan the received information using a portable programming unit and control Peabody information in the computer get a date watering time, downtime irrigation technology, the graph of actual irrigation and calculate wage irrigators, designate the date and type of maintenance and other activities. Is the method using the following device.Device for control and monitoring of irrigation installation includes sensor 1 process watering, made for example in the form of electrical contact pressure gauge (EKM) or pressure (EP) that are installed on the irrigation pipeline network last order (before irrigation installation). In order to control, to remember and to register every time the watering time (work time) and the length of time of irrigation techniques to assess the quality of irrigation, timing of maintenance, reliability and accuracy of control of the implementation process near the sensor 1, set the digital recorder 2 (ER) that contains the schema ban 3 timer 4, the circuit Assembly 5 (scheme 2), the inverter 6, the operative memory unit 7 (operational storage device is a RAM, the address counter 8, the first R1 and second R2 resistors. The first resistor and the contacts RD, attached is from an independent source E1.To read from the ICR collection, storage, view information about irrigation and simple irrigation techniques in more comfortable conditions and enter it into the computer (ECM), 9 is a portable software block 10 (BEECH), containing the first trigger 11, the first counter 12 addresses, the memory unit 13 (with the same capacity (memory), and RAM, the fifth 14 and second 15 triggers an integrating RC circuit 16, the Record button 17 (S2), the third trigger 18, the clock generator 19, the second counter 20, the capacity (memory) which is the same with RAM, the first scheme OR 21 (build 2), the imaging unit 22 of the pulse periods of the records collected in the diagram exceptions And click "Read" (recording) 23 (S3), a fourth trigger 24, the second scheme OR 25, the third counter 26, the digital indicator 27, an inverter 28, a switch 29 (S1) turn on the power source E2and differentiating RC circuit 30. To read (overwrite) the information of the connection speed of the memory block and display 10 to the recorder 2 includes a connector (plug connection R1 (R1...R1-4), and for connection to the computer connector m2 (m2-1, m2-2).Has a control device and control operation as follows.When watering crops operator (waterer) connected to the irrigation technique, hydrants or piping of irrigation network last order, waterer pressure controls the nominal mode of operation of irrigation equipment.In practice, there are often situations an objective or subjective nature, when the delay operator, serving multiple installations, irrigation positional irrigation equipment at any position is more time (the amount of irrigation norms increases, is the overuse of water). To be able to irrigate a given area (wages of waterer is made for the watered area), waterer seeks less time to keep installing the following items, as when working with continuous actions (in the case of stopping and maintenance) during the irrigation to increase the speed of their movement, reducing irrigation norm. While his actions waterer, usually not reported and does not account for further irrigation. Watering uniformity (the main indicator of quality of irrigation) over the entire area disturbed (deteriorating). In addition, waterer, so as to pour a specified area or pour as much area, seeks to increase the speed of the machine, the time to water these drawbacks, to objectively monitor the performance of all technological operations of irrigation on the same installation or on the pipeline (near electric contact pressure gauges or pressure switches 1) additional set of electronic recorders 2. With their help control (circuit - breaking contact EKM or RD), remember and record the true, actual time of irrigation (irrigation equipment) at each position, over the entire area. Moreover, the advanced control and memorize the data logger every time you stop, idle irrigation equipment within a certain period of time (for example, for 0.5 month) that allows you to make actual time schedule and downtime irrigation techniques, comparing that with the set can be assigned to specify the date and type of maintenance, to develop measures for maintenance, to assess the water quality of irrigation over the entire area for the entire period of time.To increase the productivity of workers engaged in accounting work irrigators and the calculation of their wages, the speed of the census, operative registered by the Registrar of the information in a more comfortab who I connected with the Registrar 2 and computer quick, clamp connections R1, m2. Unit 10 is a portable version and has a high rate of census information. After a certain period of time rewrite (read) from the Registrar 2 and remember in the portable unit 10 information about the job and easy for each irrigation installation.In order to link the actual timeline, work and downtime irrigation installation to calendar time, additionally register the time and date of this census, which is the point of the countdown when determining the date and end time, start and idle irrigation installation.For operational decision-making on irrigation, further commit information by the Registrar or reset it to commit the new information within the new full period, provide the registered information in more comfortable conditions. Then injected obtained and recorded in block 10 the information in the computer (PC) 9, where for a given algorithm and software specify the date, time and duration, rate of irrigation, comparing the specified and actual irrigation schedules, work irrigators, calculation of salary, specify and designate the date and type of technical obslujivaniem irrigation installation allows you to more reliably and accurately perform all operations of the technological process of irrigation and with high quality. Census information at high speed in the memory unit and display data, enter it into the computer dramatically increases the productivity, reliability and accuracy of the calculation.In the registration mode, the time of watering and idle contacts pressure switch 1 (EKM) are connected with the information input D1 of the memory unit 7 (RAM). For the same input through the first resistor R1 is supplied with a high voltage from an auxiliary power source E1. On input W/R write-read memory block 7 receives zero potential via a second resistor R2 from the same power source, allowing the data record (in this case, the unit 10 and control to the ER). In the absence of sync pulses from the block 10 scheme prohibition 3 is opened and the timer 4 generates a clock with a calibrated set period (T) of the journey. These pulses through the circuit Assembly 5 (the scheme OR come to the address counter 8 and through an inverter 6 at the counting input 7 (CE) of RAM.If the contacts EKM or taxiways are closed (irrigation installation irrigation works and produces), then the input (D1) of RAM 7 will be zero potential. Each time upon receipt of clock pulses from the timer counter input (CE) of RAM is written to the log. "0" in the cell of the RAM 7 to the address, sugavamates (the second memory) will also be written to the log. "0". This process of cell selection and write them in logical zeros will last up until the contacts KMG will not open, i.e. until the end of irrigation. In the cells of the RAM will be fixed as many zeros (m) as time continues watering (work) - tp(tp= mT).By opening contacts the sensor 1 (no pressure, equipment stands, no irrigation), at the input D1 of RAM will be a high potential. With continued receipt of pulses from the timer 4 counter input CE RAM 7 in the following cells of the memory block will be written to a logical "1". This entry log."1" (p) will last up until irrigation installation will stand and not be watering again until you increase the pressure and closes contacts 1 (idle time equal to tp= PT). The recording process of logical zeros will be repeated in the next memory cell. Thus, in the memory unit 7 (RAM) will accumulate information in the form of a series of logical ones and zeros on each watering and easy irrigation installation. The more RAM, the more the information will be stored in its memory, the greater the period of time during which it will be recorded the work and downtime irrigation installation.For online census seregion management and control 10, previously to include the supply of H2 toggle switch 29 (S1).High potential E2 through contacts R1-1 connector to the input W/R and translates RAM 7 of the Registrar 2 in the scan mode (overwrite). At the same time form a differentiating RC circuit 30 acts on the first 11, second 15 triggers, and through the second scheme OR 25 - waste tire of the third counter 26 (display counter 26 is reset to zero). The trigger 11 resets the first counter 12 of the block 10 to its original position. The trigger 15 sets the low potential input W/R2RAM 13, allowing the record (census) information from RAM Registrar 2. The indicator will be recorded zeros (counter 26 is in its original position).When the button 17 (S2) "Record" of the second counter 20 is reset, the third trigger 18 starts the clock generator 19. The signals from generator 19 arrive at the counting input of the counter 12, 20, 26 and the RAM 13, and the fifth trigger 14 of the block 10 and the input circuits of the ban 3 and the Assembly 5 of the Registrar 2. Scheme prohibition 3 blocks the operation of the timer 4. The sync pulses from generator 19 through the Assembly 5 is coming to the counter 8 and through the inverter 6 is at the counting input (CE) RAM 7. The counter 8 continues to read already the clock generator 19. At the same time the number Singen long while the address counter 8 will not receive a pulse overflow, which will bring the trigger 11 in another state. This removes the ban from the counter 12 and at the same time (in phase), starting with the first address bit is overwritten by the information from the RAM Registrar 2 in the block memory unit 10 and control. Census lasts as long as the output of the counter 20 will not receive a signal overflow, through which the second scheme OR 25 will return the trigger 18 to its original position. When this generator 19 is blocked and the census ends.After rewriting the information of the Registrar 2 in block 10 of the last disconnect from the Registrar 2 and the latter continues to record information about watering and easy sprinkler system coming from the sensor 1, since the timer 3 is unlocked and on input W/R RAM 7 again, there is zero potential.To ensure that the census is over on the same address of the RAM 7, which began with the reading of information, the address coinciding with the address of the memory block 13, is added to the counter 20, and the capacity of the counters 8,12 and 20 choose the same simultaneously, allowing you to unlock the counter 12 through the trigger 11 pulse counter overflow 8. For the ia and control 10 in the data view mode by pressing the button 23 (S3 "Reading"). This resets counter 26 of the display, the trigger 15 translates input W/R unit 13 in the reading mode (i.e., takes on this input high potential), and the trigger 24 starts the generator 19. The first pulse from generator 19 translates the counter 20 to the original position, and the counter 12 is in the start address of the free cells. The trigger 14 in conjunction with the imaging unit 22, which is built on a exception And, at the entrance of which stands an integrating RC circuit 16, translates again into the initial position, the trigger 24. Thus, the indicator 27 will display a zero value information.For the initial training data view repeatedly press the button S2 "Record", when this is set to zero, the counter 20, the trigger 18 starts the generator 19. The latter generates the clock until then, until the pulse overflow from the address counter 12 of the memory block 13. This momentum through the first circuit 21 sets the trigger 18 to its original position and thereby lock (disable) the generator 19. At the counters 20 and 26 and the indicator 27 will display information about the availability of cells (K), i.e., information about the remaining time during which it is still possible to register information about irrigation and simple irrigation techniques with the Registrar shall - registrator 2 continues to record the information.View data about irrigation and simple irrigation installation in manual mode by pressing the S3 "Reading". When this reset the third counter (display) 26. The trigger 15 sets the high potential on input W/R of the memory block 13, and a trigger 24 starts the generator 19. While the counter 12 is reset, and the counter 20 is at the last address recorded information. The pulses from the output of the generator 19 is coming to the counters 12, 20, 26, at the counting input of the IC memory block 13 and a trigger 14. In addition, the second input of the trigger 14 is receiving data (- log."0" or "1") from the output unit 13 (output TO). While information is homogeneous (one "1" or "0") trigger 14 and the imaging unit 22 do not change their state. When changing the data values of the trigger 14 is shifted in the opposite state (from "1" to "0" or Vice versa), the imaging unit 22 returns the trigger 24 to its original position. The generator 19 is blocked. However, if the data in the memory block 13 were in the form of a log."1, the trigger 14 with the arrival of the first log. "0" is translated in the zero state. The display shows the symbol "P" (plain) and the idle time-out value. If the data were in the form of a log. "0" when the first log. "1" is Oliva.Pressing the button S3 "Read" operation of the circuit is repeated and the indicator will display the value of the next idle time or watering. View exercise up until the output of the counter 20 will not receive a pulse overflow, the locking end view. View all RAM addresses, including that of free cells (i.e., the remaining registration time) and each time work and inactivity irrigation installation is finished. The indicator is fixed a dot ('.') after the symbol "P" or "P".To increase productivity by payroll, building irrigation scheduling and downtime irrigation installation analysis watering, assessing its quality, destination, date and type of maintenance data from the program control unit and control 10 is automatically entered into the computer through the plug connection m2.The use of the described device for its implementation will more reliably and with high accuracy to control the technological process of irrigation, to improve the quality of irrigation and productivity, objectively and in a timely manner to carry out maintenance and repair, irrigation installation, etc. 2.
