Abstract

Embodiments of the present invention provide a fault detection method and device for electro-pneumatic equipment. The method includes: collecting air pressure, gas temperature, and gas volume data of pneumatic components at each set time; The gas temperature and gas volume data are converted to the air pressure and motion data at each set displacement; then the performance data at each set displacement is calculated by using the air pressure and motion data at each set displacement, so that the The performance data is compared with the design performance data to determine the health state of the pneumatic components. Compared with the existing manual detection method, this method can detect the fault state in time and provide a basis for the operation of the electro-pneumatic equipment. In addition, this method can also realize fault prediction.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of electro-pneumatic equipment, and in particular, to a fault detection method, device, equipment and storage medium for electro-pneumatic equipment. Background technique [0002] Electronically controlled pneumatic equipment is an important equipment widely used in rail transportation, manufacturing, mining, oil and gas extraction, chemical industry, water supply and drainage, and environmental protection. In addition, the control mode of the electro-pneumatic equipment is electronic control, and the driving mode is pneumatic. For example, electro-pneumatic valves are important components of various pipelines, and their main structures include pneumatic components (such as cylinders), pistons or diaphragms, springs, pneumatic rods, and connections between pneumatic rods and loads (such as valves). Its working principle is that when the electro-pneumatic valve receives the valve openin...
