(57) Abstract:Usage: in industry, in particular in the means to control the spray nozzle. The inventive control system nozzle spray in a certain position switch signals from the timer, the beginning of which is synchronized with the operation of the limit, proceed to the counting input of the decoder. Composition field at the output of the decoder is built on the issuance of the necessary impulse from the calculated, after which the signal starts the pump liquid supply, because the synchronization can be done with a given accuracy at any angular speed of the shaft of the motor. 1 Il. The invention relates to the field of engineering, namely, controls the operation of the injector spray.A known control system of the nozzles of the spray, including the contact system, which synchronizes the time of filing dose of water at a particular phase state of the rotor gear. This system allows you to accurately choose the time of filing the water, but it is rather "hard" setting, i.e., the change of the moment of submission of the dose can be done only by the configuration of the mechanical contacts, which is quite truncates, associated with key management. In this case the time of filing the dose of water is also determined by the configuration of the contact group whose signal is amplified and fed to the actuators. The restructuring of the system in this case is also related to the configuration change of the contact group, which is time-consuming and not always possible.Closest to the present invention is a control system of the nozzles of the spray containing the timer, control keys, node synchronization, and the input terminals of the control signals "pause", "irrigation dose", "system startup" and output terminals of the control of the motor-reducer" and "pump control".In this case, the synchronization is carried out by removing the signal from the contact group, but the running gear is already being implemented through an electronic circuit that allows easy enough to modify system settings.However, in this case it is impossible to maintain the parameters of the start point of liquid supply, supply time and synchronization time of filing with the work gear motor (for driving mechanical parts of the system).The aim of the invention is economially both parameters, i.e., improvement of operational parameters of the system.This goal is achieved by the fact that the system is equipped with a decoder Executive teams, the timer is equipped with an electronic keys pause mode, start time and watering duration of irrigation, and site synchronization is made in the form of RS-flip-flop and five logical comparison keys and generate control signals, and the terminal of the control signal "pause" is connected to the first input of the first logical key comparison and generation of control signals, the second input is connected with the first output of the RS flip-flop and an output connected to the input of an electronic key and the pause mode and the first input of the second logical key comparison and generation of control signals, the second input of the latter is connected with the output of timer and counter input decoder commands, and the output to the first input of the third logical key comparison and generation of control signals, the second output of the RS flip-flop connected to a second input of the third logical key comparison and generation of control signals, and its output through the first control switch with output terminal "control of the motor-reducer". In addition, the input terminal of the control signal "system start" tie is showing connected at least to the corresponding first two even-numbered outputs of the decoder Executive teams and the output to the first input of the fifth logic key comparison and generation of control signals, the second input is connected with the second output of the RS flip-flop and the output to the inputs of electronic switches start time and watering duration watering timer, and an input terminal of the control signal "watering with a dose associated with the first installation input RS-flip-flop and through the key element to the input of the initial installation of the decoder, Executive teams, and the entrance of the self-locking key element is connected to the even-numbered outputs of the decoder Executive teams the output of one of the last bits associated with the second installation input RS-flip-flop, in addition, one odd output of the decoder Executive teams prior to the last connected even, is connected through a second control switch with output terminal "pump control".Analysis of patent and scientific literature showed that the claimed combination is unknown, i.e. the invention conforms to the criterion "novelty".Because the system is assembled from known electronic components, the invention meets the criterion of "industrial applicability".As well as the use of systemcost, the invention meets the criterion of "inventive step", as known tools do not provide such a simple electronic means similar effect.The drawing shows a schematic diagram of the system control the operation of the injector spray.The system contains a node synchronization, which is made in the form of logical keys 1-5 comparison and generation of control signals, RS-flip-flop 6, a decoder 7 Executive teams, two keys 8 and 9 management, a key element 10, 11 timer with electronic keys pause mode 12, start time 13 irrigation and the duration of irrigation 14, and the input terminals are terminals "system startup" 15, "pause" 16, "irrigation with a dose of" 17, and the output is a "pump control" 18, "managing the motor-reducer" 19. The system has a ground terminal 20 and the power supply 21, and is provided by the elements 22 power protection. The system is connected with standard equipment, including switch 23 selection of the mode, the relay 24 run, the pump 25 from the fluid, and engine power gear 26 connected with the end 27. When this switch 23 through the input terminals 15-17 associated with keys 1-5 and the timer 11, the output of which is connected to the input of desip is, the key 9 - the pump 25.The system works as follows.According to the scheme switch 23 in the "0" mode the system is in standby mode "1" motor (the motor 26 operates continuously at a reduced speed, in the mode "2" - also with full speed.In the position of the switch 23, the mode "3" engine 26 is started only when a relay 24. For this purpose, the switch 23 and the first output of the trigger 6 to the inputs of the first logical key 1 is logic "1". "0" at the output of this key 1 opens the key 12, the system starts a timer 11 with a timing chain R4-R6, C1, C2. From the output of the timer 11 drop to "0" will yield a second logical key 2 logic "1", which through the third logical key 3 and key 8 includes the relay 24, the contacts K1 which runs the motor 26, the shaft of the latter performs one revolution and remains in its original position until the next pulse from the output of the timer 11. The pause time depends on the position of the engine R4. In this mode, the flow of the liquid in the mixer is blocked.In the position of the switch 23 "4" trigger 6 moves to a state that allows operation of the counter decoder 7 for counting the number of revolutions of the shaft, node synchronization operation start time the timer 11. R 26 sets the time the fluid (dose), and R7 adjusts the commencement of operation of pump 25. The logic of the programmer on the decoder 7 supplies doses of liquid at the first turnover of the shaft of the motor 26 (item 1 of the decoder 7, the key OUT, OUT). Subsequent revolutions of the shaft from the motor 26 runs without fluid or after the specified number of turns the device goes into standby mode. Elements AT key element 10 and R23, and R11 when the hold switch 23 is in position "4" supply of fluid each revolution of the shaft of the motor 26. The dose can be submitted in advance at any point in the operation of the motor 26. The synchronizer delivers fluid at a fixed time regardless of the effect on the switch 23. The filing dose may occur at a fairly fast speed of the shaft of motor 26 that when the manual control makes it impossible to supply fluid at the right time at all. In addition, the accuracy of commencement of supply is achieved by approximation logic device pulse from the end 27 of each revolution of the shaft of the motor 26 regardless of its angular velocity.The advantage of this system over the known devices of this assignment is the ability to work the Toyota of the end 27 of the pulses from the timer 11, that provides high accuracy and robustness with long-term system operation. Diodes UD-UD are software field, which can be easily reprogrammed for each situation. The logic system monitors the status of the controls and the position of the end closure 27 in the "dead zone", i.e. during the transition of the end closure 27 in position.
