Embodiment Construction

[0024] The present invention will be further described in detail below in conjunction with specific embodiments.

[0025] A device fault self-diagnosis method, comprising the following steps:

[0026] S1: Obtain the working environment information, working intensity information and usage time of the equipment to be diagnosed.

[0027] Specifically, the equipment to be diagnosed may be switching equipment, such as electric valves, relays, switches, etc.; it may also be power equipment, such as motors, generators, hydraulic cylinders, cylinders, etc.

[0028] Acquisition of working environment information includes the following steps: selecting different environmental sensors according to different devices. For example, when the equipment is an electric valve, the flow metering sensor that has a great influence on the loss of the electric valve is selected for detection, and the flow through the electric valve is detected in real time through the flow metering sensor, and the f...

Abstract

A device fault self-diagnosis system and method, the method comprising the following steps: obtaining the working environment information, working intensity information, and service time of the equipment to be diagnosed; obtaining the equipment loss coefficient K under different working environments and the The equipment loss coefficient D; according to the equipment loss coefficient K under the current working environment, the equipment loss coefficient D under the current working intensity, and the service time t under this condition, the loss value S of the equipment is calculated; the obtained loss value is compared with The set value is compared, if it is greater than the set value, a prompt will be given. The invention also includes a device fault self-diagnosis system. The invention can maintain and replace the equipment in advance, prevent accidents before they happen, greatly extend the service life of the equipment, reduce unplanned downtime, and ensure long-term stable operation of the system.

Description

technical field [0001] The invention relates to the field of equipment systems, in particular to a system and method for equipment fault self-diagnosis. Background technique [0002] Existing equipment fault detection is usually processed and monitored by a PLC controller. The PLC controller reads the detection information of the sensor and performs a series of logical judgments to confirm the operating status of the system. When an abnormality occurs, the corresponding emergency measures are taken. However, this method is limited to processing after the failure occurs, and cannot maintain and replace the equipment in advance, which greatly reduces the service life and work efficiency of the equipment. Contents of the invention [0003] The purpose of the present invention is to overcome the above-mentioned shortcomings of the prior art and provide a fault self-diagnosis system and method for equipment with long service life and long cycle operation. [0004] Technical sc...
