Problems solved by technology

These consumable mechanical components are basically handled by corrective maintenance or regular replacement, because some embedded systems are life-critical systems, such as the launch button of weapons, the operating keyboard of emergency equipment, the chemical industry, etc. Valve control relays / switches, etc., so this method of after-the-fact maintenance or regular replacement has great hidden dangers

[0033] figure 1 The flow chart of the first embodiment of the method for detecting the service life of consumable mechanical elements of the present invention is shown. See figure 1 , the implementation steps of this embodiment are described in detail as follows. In this embodiment, the keyboard is used as an example for illustration, and it may also be any other mechanical components that are easily worn out, such as switches.

[0034] Step S101: Detect whether it is a new keyboard.

[0035] Step S102: When a new keyboard is detected, a new service life is set and stored for the new keyboard.

[0036] This life value can be the life value provided by the manufacturer, or it can be the life value after derating confirmed by the application system provider or the end user according to the actual operating environment.

[0037] A non-volatile memory can be installed in the electronic device (such as an embedded system) to which the keyboard belongs, and the parameters can be...

Abstract

The invention discloses a method for detecting the service life of a prone-to-loss mechanical component and an electronic device. According to the invention, the service life of probe-to-loss mechanical components is detected and evaluated in a simple and low-cost mode, the maintenance personnel are reminded to process timely at the arrival of the service life, and various damages caused by problems of the mechanical components are avoided at a minimum cost. The technical scheme is that a service life value is set in advance before the prone-to-loss mechanical component is used for the first time; use actions of the mechanical component are detected, each use action performs counting on the actual use number of times, and the prone-to-loss mechanical component is judged to be replaced when the actual use number of times reaches the service life value.

Description

technical field [0001] The invention relates to a method and a device for detecting the service life of easy-to-wear mechanical components such as a keyboard or a switch in an electronic device including an embedded system. Background technique [0002] Various mechanical keyboards / switches / relays are usually used in embedded systems for human-computer interaction, detection, and control purposes. Manufacturers usually disclose the working life, such as 100,000 times, but general application systems have not evaluated its remaining Lifetime, such as the number of times a production line detects switch / relay actions or the number of times a button is pressed. These consumable mechanical components are basically handled by corrective maintenance or regular replacement, because some embedded systems are life-critical systems, such as the launch button of weapons, the operating keyboard of emergency equipment, the chemical industry, etc. The valve controls the relay / switch, etc...
