The system works as follows.

On the central control unit 22, the key identifier is set to the position "Closed, affecting the dose dialing unit 31". Then, using the button to switch the display of the scoreboard, set the dose indication on it and set the required amount of oil in liters with the help of the corresponding buttons on the dose sensor. This value is stored in dose register 30 and is displayed on the scoreboard. The key-identifier is turned to the “Open” position, affecting the block 31 of the dose set permission, disabling the dose setter 32 from the dose register 30. The green (enabling) signal of indicator 19 lights up at the corresponding loading station.

Next, the lug 42 of the grounding cable 43 of the container 3 is inserted into the socket of the locking device 18 and secured.

The tank truck is grounded. Then, the output t of the hinge pipe 10 from the initial "garage position." At the same time, according to the signal from the automation unit 21, the indicator 19 switches from the green to the red (prohibiting) signal. Then connect the hinge pipe 10, the vapor

line 13 and line 15 to COOT-

capacitance devices 3. The system automatically controls the sequence of operations. In case of failure of any preparatory operation or the transient resistance of the grounding circuit exceeds the permissible value, a prohibitory signal is generated in the automation unit 21 and the loading process is blocked. Next, the previous readings of the counting device 6 of the liquid are reset to "zero", the key-identifier is inserted and turned, and the "Start of the local control panel 20 control button is pressed. As a result, the automatics unit 21 turns on the electric motor 2 of the pump I and sends a command to open the shut-off device 7, the filling process begins. The incompletely open position of the slam-shut device 7 corresponds to reduced system performance. Fluid entering the tank 3 at the loading station is signaled by varying readings on the scale of the meter 6 liquid. At the same time, in the sensor 8 of the liquid counter 6, DC pulses are formed, which are proportional to the amount of liquid poured in, which are supplied through the local control panel 20 and the automatic control unit 21 to the central control panel 22. When switching the display of the digital display from the dose to the current value, this number will be displayed on the digital display of the central control panel 22 of the control.

The DC pulses of the sensor 8 are supplied through the matching unit 26 to the metering device 23 of the central control panel 22 to the register 28. In addition, in the register 28, the equalizer 27 corrects for the viscosity of the fluid, the geometric parameters of the shut-off device 7, and other data affecting the closing time of the slam-shut device 7. The outputs of the register 28 and the dose register 30, in which the value specified on the dose setter 32 is stored, are fed to the comparator 29, where they are equalized. In case of equality of codes by the comparator 29, the control unit 21 is given a control signal at the filling end through the autolithic unit 21 and the local control panel 20, the shut-off device 7 is closed and the electric motor 2 of the pump 1 is turned off.

In the process iia.iHBa, imiu.chsy from the sensor 8 of the liquid counter 6 through the local control panel 20 and the automatic control unit 21 arrive at the input of the register 34 of the current value of the performance control device 24 of the central control panel 22 of the control.

The output of the current value register 34 is connected to one of the inputs of the analyzer 35, the second input of which is connected to the dose register 30 of the metering device 23. When the analyzer 35 loads a certain amount of liquid, the value of which depends on the capacity of the tank 3, it gives a signal to the memory element 36 TI, which generates the control signal. By this signal, passing through the automation unit 21 and the local control panel 20, the shut-off device 7 is fully opened and the filling continues at the nominal capacity. The pulses of the sensor 8 simultaneously arrive at the input of the register 33, the output of which is connected to one of the inputs of the comparator 37. The second input of the comparator 37 receives signals from the register 30 of the dose of the metering device 23. The comparator 37, comparing these signals, 50 liters before the end of . the seam forms a signal which p-acts on the memory element 36. From this control the control signal through the automatic control unit 21 and the local control panel; | 20 enters the slam-shut device 7. The village cover is covered, and topping 1 () 01 comes down with reduced productivity.

In the process of filling, an automatic: automatic control of equipment liciipaijiiocTbio is carried out. By the command “Start with local H) 1; .lta 20 controls, 1c;:. (n through the automatic control unit 21 enters cin-Ha; i into the prohibition element 39, and through 1H) the passage of pulses tpkgovo begins: -o generator 38 to the counting input to the frequency 40. At the same time, the installation input of the frequency divider 40 receives pulses from sensor 8, setting it with each pulse to the initial state. In the event of a malfunction of the equipment at the input of the frequency divider 40, there is no img / a sensor of the sensor 8. At the same time, at its output with a time delay, a signal is generated to stop filling. The incompatibility of the equipment on the central control unit 22 is indicated by the corresponding indicator 41.

Stop pouring. You can at any time. To do this, it is enough to press the button “Stop, respectively, local 20 nln central 22 zero control. The downflow is also terminated by the signal from the sensor 16 of the upper limit level. In these cases, the signal from the automatic control unit 21 is turned off by the electric motor 2 of the pump 1 and the shut-off device 7 is closed.

The end of filling is indicated by the cessation of changes in the indicators on the scale of the meter 6 liquid. The gas outlet line 13, the communication line 15 and the hinge pipe 10 are disconnected from the tank 3 and the P1 1 connection head 11 is placed in its original "garage position" in the locking device 18. Then the tip 42 with the ground cable 43 is returned to the tank 3, the key is removed. ID from the local control panel 20. The red light goes out and the green (enable) signal of the indicator 19 lights up.

The key identifier is returned to the central control panel 22 of the control unit and turned it into a shutdown function. Closed. The system returns to its original state.

The application of the proposed system makes it possible to increase the loading accuracy and to take the liquid into account, both according to the meter readings and dose, with an accuracy of ± 0.5%, necessary for commercial accounting. This circumstance makes it possible to issue shipping documents and, by the same token, significantly reduce the service time of the tank truck at the tank farm.

The presence in the system of automatic control over the operation of the equipment of the pump unit, the shut-off device, the fluid meter with the sensor, and the communication line of the filling station with the control room during the loading process allows for timely repair and replacement of faulty equipment.

Blocking a digital scoreboard with an identifier key does not allow changing the indications of the center console until the key identifier is returned, and allows the operator to control the actions in order to prevent misuse.

Monitoring the grounding of the tank truck during the filling process, limiting the flow rate of the liquid at the beginning of the loading in accordance with the requirements of the safety regulations to 1 m / s, allows to REVIEW the level of safety and reliability of the system
