Further, referring to fig. 2, fig. 2 is a schematic circuit diagram of a tank truck charging and discharging control device according to an embodiment of the present invention, it can be understood that the valve control module, the power switch module 300, and the emergency control module 400 are switches for implementing different corresponding functions, and most of the switches are manually operated switches due to the need of manually performing the tank truck charging and discharging operations, which are more suitable for application scenarios, and only the liquid phase pipeline cut-off valve is additionally provided with an automatically controlled switch function. The valve indication module comprises a plurality of indication lamps, and the on-off states of different valves are indicated by the illumination of the indication lamps and different colors, such as green, yellow and blue. With continued reference to fig. 3, fig. 3 is a schematic diagram of an interface of the tank truck charging and discharging control device according to an embodiment of the present invention, where each terminal number (interface) is used for externally connecting terminals, and at the same time, part of the terminal numbers are respectively in one-to-one correspondence with the terminal numbers in fig. 2.

In this embodiment, the tank truck charging and discharging control device according to the embodiment of the invention is powered on by turning on the power switch module 300, so that the state of the pipeline system is displayed on the display module 100. Therefore, when the related personnel fill and discharge the tank truck, the tank body is filled and discharged with the medium based on the visualized pipeline system state, once the pipeline system state is unsafe, the alarm module 200 will give an alarm to remind the related personnel to operate the valve control module, and the related personnel will operate the valve control module based on the indication condition of the valve indication module to correspondingly open or close the related valve of the pipeline system of the tank truck, so that the tank truck is prevented from being filled and discharged under the condition that the tank body is under negative pressure or overpressure. Therefore, by utilizing the tank truck charging and discharging control device provided by the embodiment of the invention, the liquid level and the pressure of the medium in the tank body of the tank truck are monitored in real time, so that the operation safety of related personnel is ensured, and the occurrence of safety accidents is reduced to the greatest extent.
