The invention discloses a service life prediction method and device of a switch contact, electronic equipment and a computer medium. The method for predicting the service life of the switch contact is applied to the electronic equipment with the switch contact. The method comprises the following steps: collecting the contact temperature at the position of a switch contact, collecting the environment temperature inside the electronic equipment, and collecting the working current passing through the switch contact; calculating a contact temperature rise between the contact temperature and the environment temperature, and calculating a temperature rise coefficient according to the contact temperature rise and the working current; obtaining at least two temperature rise coefficients, and processing each temperature rise coefficient to obtain an abrasion threshold value of the switch contact; and comparing the wear threshold value with a preset threshold value, and outputting a service life prediction prompt of the switch contact according to a threshold value comparison result. According to the invention, accurate prediction of the service life of the switch contact is realized.
Description
technical field [0001] The invention relates to the field of electrical equipment, in particular to a life prediction method, device, electronic equipment and computer medium of a switch contact. Background technique [0002] Switch contacts in electronic equipment are directly related to the safety of equipment operation. If the switch contacts of electronic equipment fail, it is easy to cause safety accidents, which will not only cause huge economic losses, but also endanger personal safety and cause extremely bad social impact. . [0003] In recent years, with the continuous advancement of computer technology, the use of data acquisition and analysis to monitor switch contacts in electronic equipment has been widely used; through data analysis of switch contacts in electronic equipment, life prediction has become particularly important, due to the inclusion of There are many types of electronic equipment for switch contacts, and the drawer switch cabinet is used as an ex...
