Electric automation equipment fault detection system

Abstract

The invention discloses an electrical automation equipment fault detection system, and relates to the technical field of automation equipment fault detection. The system comprises an equipment parameter storage module, an electrical automation equipment operation database in a fault-free state, a fault self-checking module, a fault early warning module, an operation control signal stopping and feedback unit, a fault feedback timing unit, an emergency shutdown unit and a main control system. By arranging the operation control signal stopping and feedback unit, the fault feedback timing unit and the emergency shutdown unit, the operation control signal stopping and feedback unit can be used for stopping a control instruction sent by the main control system, so that the phenomenon that the electrical automation equipment is damaged due to the fact that the electrical automation equipment still continues to execute the operation instruction at the fault stage is avoided; the fault response time efficiency of the whole system can be improved by utilizing the fault feedback timing unit, the response control can be carried out in time under the condition that the main control system does not carry out feedback after the emergency shutdown unit is matched, and the operation safety and stability of the whole system are high.

Description

technical field [0001] The invention relates to the technical field of automation equipment fault detection, in particular to a fault detection system for electrical automation equipment. Background technique [0002] Electrical automation equipment is generally used in a more complex environment, and the environment used is often harsh and dusty, so electrical automation equipment is very prone to equipment failures, and some failures are often difficult to detect after they occur. It will only be noticed when a certain function is used, which will cause false signals and misoperations to electrical automation equipment, which will cause damage to the products to be produced, and may even cause personal equipment safety accidents in serious cases, so in advance Avoid accidents and product damage when electrical automation equipment is found to be abnormal; [0003] The current electrical automation equipment fault detection system has the problem of slow response time.

[0002] Electrical automation equipment is generally used in a more complex environment, and the environment used is often harsh and dusty, so electrical automation equipment is very prone to equipment failures, and some failures are often difficult to detect after they occur. It will only be noticed when a certain function is used, which will cause false signals and misoperations to electrical automation equipment, which will cause damage to the products to be produced, and may even cause personal equipment safety accidents in serious cases, so in advance Avoid accidents and product damage when electrical automation equipment is found to be abnormal;

[0003] The current electrical automation equipment fault detection system has the problem of slow response time. When a fault occurs, the main control unit cannot perform control operations in time, and the control operations are often only performed through the main control unit, and the response delay occurs in the main control unit. When the fault situation cannot be controlled in time, the stability and efficiency of the detection system are low; therefore, the present invention proposes a fault detection system for electrical automation equipment to solve the deficiencies in the prior art
