Electric device fault detecting system

Abstract

The invention provides an electric device fault detecting system which comprises an acquisition module, a fault diagnosis device, a diagnosis monitoring device and a warning device. The acquisition module is used for acquiring parameter information to be detected of an electric device. The fault diagnosis device is used for adjusting a preset range of standard parameter information and / or controlling the warning device to send prompting information to a worker according to the parameter information to be detected. The diagnosis monitoring device is used for monitoring diagnosis data, curves and a device state. The electric device fault detecting system automatically conducts real-time monitoring on the fault situation of the electric device, improves detection efficiency, avoids production accidents, uses the fault diagnosis device to automatically adjust the preset range of the standard parameter information memorized internally according to a detected result, enables the working state of the electric device to form a closed loop monitoring, can timely recognize abnormal state and faults, sends the device fault prompting information to the worker in real time, does not need to shut down the electric device and ensures normal work of other devices.

Description

technical field [0001] The invention relates to the field of fault detection of electrical equipment in an automatic control system, in particular to a detection system for faults of electrical equipment. Background technique [0002] Electrical equipment should be managed during operation and regularly inspected to ensure the normal operation of the equipment and to protect the safety of users. At present, the electrical equipment is managed through the production system, but when the production system fails, it will affect the normal operation of the production, and the current manual search for the cause of the failure is time-consuming and laborious, which can no longer meet the production needs. [0003] In order to solve the above problems, a protection system for electrical equipment is provided in the related art, including a heating relay and an AC contactor. The heating relay monitors the current value of the electrical equipment in real time. Once the current valu...

Problems solved by technology

[0004] The inventor found in the research that in the prior art protection system for electrical equipment, once the electrical equipment is damaged, the current is overloaded, the equipment is shut down, or the equipment is not started according to the automatic control command, etc., it is necessary to stop the equipment and manually search for the fault. , it is necessary to identify which parts of the control software, lines, equipment, etc. are faulty, which makes the operation cumbersome and inefficient, and the shutdown of the equipment also brings a certain loss to production
