Technical Field

The invention relates to the technical field of intelligent control, in particular to a method, a device and equipment for evaluating the health of an electromagnetic valve and a computer readable storage medium.

Background

In daily production life, more solenoid valves are used in many occasions, for example, more solenoid valves (such as a control air door solenoid valve) are used in rail vehicles (such as high-speed trains), the solenoid valves are vulnerable devices, and some solenoid valves of the rail vehicles are opened and closed for more than ten thousand times every year.

The existing management modes of the electromagnetic valve are generally divided into three types, wherein one type is to replace the electromagnetic valve after the electromagnetic valve is damaged; one is that in daily maintenance or other maintenance, whether the maintenance is normal or not is tested, and the maintenance is carried out under the condition of damage; the other is the expected number of use times, and the use times are uniformly replaced before the expiration or in the overhaul. However, the above three management methods all have respective disadvantages, firstly, the solenoid valve is replaced under the condition of being damaged, so that the online operation is influenced, the replacement condition is generally urgent, and the damage of the online solenoid valve may cause short circuit and the like, so as to cause other damages. Secondly, when the inspection is carried out during daily maintenance, one-sidedness exists, which does not represent that the inspection is normal, and the operation is normal within a period of time. Further, in the case of the expected number of uses and replacement during overhaul, individual differences are not taken into consideration, and sometimes solenoid valves with good individual performance are replaced, and some individuals with a small number of uses or a small amount of use time may have problems before overhaul.

In summary, how to effectively solve the problems that the existing electromagnetic valve management mode influences on-line operation, has one-sidedness, does not consider individual differences and the like is a problem which needs to be solved urgently by a person skilled in the art at present.
