The invention relates to technical cybernetics and can be used for dosed dispensing of liquid materials, such as oil products, piece goods moving along a conveyor, as well as in process control systems.

A known fuel dispensing control system, comprising a counter with a reading device, a pulse sensor, and a control panel, comprising a set of dose sets and automatic shutdown of the pump unit i.

. The closest to the technical essence and the achieved result to the invention is a remote control system for dispensers, including a metering device with contact sensors and a single supply meter with an electromagnet and a button for setting the counter to zero position mounted on the dispenser column, a column selection device, a dose dialing device and one module consisting of consecutively located counters Neny signal generating circuit stops driving of the dispenser, and Start and Stop buttons 2 "

The disadvantages of the known system are fuel losses (the use of a single module makes it difficult to control and control all dispensers simultaneously), the system’s reliability is low (the control panel is made on an electromechanical element base with a large number of moving parts requiring a large amount of electricity) as well as poor performance due to difficult access to individual structures during repair and the need for additional maintenance costs.

The purpose of the invention is to reduce fuel losses, increasing system reliability and performance.

The goal is achieved by the fact that the fuel dispensers remote control system, which includes a metering device with contact sensors and a one-time meter, fuel dispensing with an electromagnet and a button for setting the meter to zero position installed on the fuel dispenser, column selection device, device a set of doses and a module consisting of consecutive meters, a comparison circuit, a circuit for forming a signal to stop the dose drive torus and Start and Stop buttons, additionally contains a device for setting a discrete count, an electromagnet activation button, additional modules for controlling each column, made similar to the main module and installed in parallel, the latter being equipped with a digital display unit connected to the counter, and the inputs of the module are set up with a device for setting discrete counting

Fig. 1 shows a block diagram of a remote control system for fuel dispensers; in fig. 2 - remote control, general view.

The system contains a matching device 1 with matching elements 2 and a line filter 3, a metering device 4 with contact sensors, fuel dispensers 5 with counter indicators 6 for one-time fuel supply, electromagnets 7 and buttons 8 for setting the counter pointer to zero (Fig. Only one of the four dispensing dispensers is shown), the device 9 sets the discreteness of the account, the switch 10 discreteness of the account, the button AND select the column, the device 12 set the dose, the buttons 13 turn on the electromagnets 7, four and identical module 14, in which fuel metering meters 15 are located, digital display devices 16, comparison circuits 17, metering drive stop signal circuits 18, buttons

19 and 20 Start and Stop, I

The device works as follows.

The operator, by pressing the column selection button, prepares the corresponding counter 15 for recording the dose, while the remaining counters are locked and new information cannot be recorded in them

By pressing the keypad button of the device 12 in the dose, the dose is recorded in the counter, and the value of the recorded dose highlights the mouth5 1

16 digital display. By pressing the Start button 19, the dispenser drive stop signal forming circuit 18 is blocked and a signal is given to turn on the dispenser drive through matching device 1 When the metering device 4 is in operation, the contact sensor is closed. Each contact of the contact sensor corresponds to 1 l or 5 l fuel release. The signal from the contact sensor is fed to the counting resolution device 9 Depending on the position of the counting switch 10, a single pulse or a series of five pulses are generated at a single closing of the contact sensor. These pulses are fed to the input of the counter 15, which operates in the subtraction mode. Upon reaching the zero state of the counter 15, the comparison circuit 17 generates a signal that acts on the stop signal generator circuit 18, as a result, the drive of the metering device 4 stops. Dosing device -4 is kinematically associated with a 6-time counter counter indicator

Before each release of the fuel, the counter indicator 6 must be set to the zero position, since

only in this case the blocking in the starting circuit of the dispenser drive is released. On the fuel dispenser 5 setting the pointer to the zero position

5 is made by the consumer using button 8, and the operator using buttons 13. This activates the electromagnet 7, which sets the pointer to the zero position and unlocks the metering drive circuit. When the Stop Button 19 is pressed, the module 14 generates a signal to stop the dispenser drive, and the information in the counter 15 is stored.

5 Pressing the Start button 20 resumes the fuel release.

The use of the proposed system of remote control of fuel dispensers allows to reduce fuel losses in the installation of separate Start and Stop buttons for each column and to introduce into the control panel a counting resolution device, as well as to increase reliability by running the control panel on an electronic circuit. At the same time, the performance of the system is enhanced by facilitating access to the individual structures during repair and reducing maintenance time.
