[0003] The device and system consist of a dynamic operating condition simulation module, a high-precision sensing and detection unit, a data acquisition and analysis system, an intelligent early warning platform, and a remote monitoring terminal. The operating condition simulation module reproduces the flow and pressure changes of the actual operation of the refueling truck. The sensing unit synchronously collects the dynamic response data of the pressure control system. After processing by the analysis system, the data is compared with preset standard parameters to evaluate the pressure control accuracy, stability, and fault risk, generate a visual detection report, and push abnormal data to the early warning platform and remote terminal in real time.

An installation rod 59 is fixedly installed on the outer shell 1. A fixed... A baffle 510 is installed, and an inclined plate 511 is fixedly installed between the baffle 510 and the outer casing 1. Multiple sets of mounting cylinder 52, air inlet 53, motor 54, short rod 55, fan blade 56, circular filter plate 57, exhaust port 58, mounting rod 59, baffle 510 and inclined plate 511 are provided.

[0031] In this embodiment, when the device is running, the mobile power supply 44 generates heat, which starts the motor 54 on the mounting cylinder 52, driving the short rod 55 and fan blade 56 to rotate. Outside cold air enters the mounting cylinder 52 through the air inlet 53, and after being filtered by the circular filter plate 57, it is blown in a direction towards the mobile power supply 44 to quickly dissipate the operating heat and prevent circuit failure caused by high temperature. Multiple sets of exhaust holes 58 and inclined plates 511 form a convection channel to accelerate the discharge of hot air. The baffle 510 cooperates with the inclined plates 511 to block outside dust and moisture from entering the interior of the outer casing 1, preventing internal components from getting damp and rusting.

[0033] In this embodiment, during the detection process, the electronic components and detection pipes 46 inside the information acquisition box 43 will generate residual heat. The exhaust fan 63 in the square slot 61 is activated to draw in the air outside the outer shell 1. The air is initially filtered by the grid plate 62 and then filtered a second time by the dustproof plate 68 to remove dust particles from the air, preventing dust from affecting the heat dissipation of the components and the detection accuracy. The air guide plate 64 guides the clean airflow to flow evenly through the area of ​​the information acquisition box 43 and the detection pipes 46, carrying away the residual heat. The airflow finally circulates through the ventilation slots 65 on the top explosion-proof plate 41, ensuring that the internal temperature of the outer shell 1 is uniform and avoiding local overheating that could affect the accuracy of the detection components, thus providing a stable environment for the accurate acquisition of pressure signals.
