In a preferred embodiment of the present embodiment, the control device 3 includes a PLC controller and a touch panel.

The automatic control of the liquid split charging of the whole steel cylinder is realized through the configuration of the PLC and the touch screen. The steel cylinder is fixed by the aid of the air cylinder and the buffer damping device. The cylinder controls the on-off of the gas circuit through the electromagnetic valve, so that the fixation of the steel cylinder is realized through the action of the cylinder. And a magnetic photoelectric switch is arranged on the cylinder, and after the cylinder is fixedly pressed on the steel cylinder, the magnetic photoelectric switch can feed back a corresponding in-place signal to the PLC. After time delay, the pneumatic filling valve of the liquid filling pipeline is automatically opened. And starting filling operation after the filling valve is opened, realizing data setting of a filling target value through data setting of a touch screen, and cutting off the filling valve when the net filling weight reaches the target weight. And (4) delaying after the filling valve is cut off, simultaneously judging the pressure of a filling pipeline behind the filling valve, and automatically opening the liquid bypass emptying valve when the pressure exceeds a safety set value to discharge redundant liquid behind the filling valve to an inlet pipe network. After the pressure is discharged, the cylinder is reset, and the steel cylinder is released. In the liquid filling process, the effect of pressurization is realized by increasing a liquid booster pump in consideration of the fact that the liquid pressure of the raw material device is continuously reduced along with the amount of liquid, and the frequency change is automatically realized according to the increase and reduction of filling stations. When the filling operation is more, the frequency is automatically increased, when the filling operation is less, the frequency is automatically reduced, and when the pressure is over-pressure, the booster pump is automatically stopped. When no filling operation is performed, the frequency is automatically reduced to a reasonable range, repeated stop under overpressure is avoided, and the workload of operators is increased. The emergency stop and reset buttons are added on the control box and the panel to realize double insurance of emergency treatment and simplicity of reset operation.

After the start button is pressed, the two-position five-way electromagnetic valve is electrified, the piston rod in the cylinder moves to push the steel cylinder to move towards the front part, the steel cylinder is pressed and fixed and then fixed, the photoelectric switch at the pressing position detects the pressing position, and the photoelectric switch at the separating position detects the separating position.

The specific operation steps are as follows:

the first step is as follows: selecting filling stations, setting a net filling target value through a touch screen, and setting target frequency setting for realizing automatic switching according to the number of stations in online filling operation;

the second step is that: the pneumatic start operation filling valve button can be started, and the start of a filling panel or the start of a touch screen picture can be realized;

the third step: and when the filling operation is started, the electromagnetic valve on the air cylinder is automatically opened to push the air cylinder to compress the steel cylinder, the target is fixedly compressed to fill the steel cylinder, the steel cylinder is compressed in place, the switch state in place is detected, the target filling valve is opened in a delayed manner when the conditions are met, and the filling operation is started. When the net filling value reaches the filling set value, the filling valve is automatically cut off, the medium pressure behind the filling valve is judged at the same time, when the pressure is too high, the bypass emptying valve is automatically opened, the pressure is released, the judgment of the pressure is continued, and when the pressure is lower than the safety set value, the air cylinder pressing device is released, and the current filling operation of the current station is completed. In the filling process, different stations of the cylinder pressing device and the placing condition of the steel cylinder are actively judged, and when the pressing is not in place and the steel cylinder is not placed, the interlocking protection device is automatically realized;

the fourth step: and judging the filling speed in the filling process, and starting the booster pump. Meanwhile, the frequency given value of the variable frequency motor can be automatically adjusted according to the number of the filling stations opened on line, the filling pressure is adjusted in real time, and the overpressure phenomenon is avoided. When an accident occurs, the emergency stop button is pressed down urgently, and reset is carried out through the reset button after elimination.
