Embodiment Construction

[0037] In order to make the technical problems, technical solutions and beneficial effects solved by the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0038] For many battery-powered products, in order to save power, the MCU (Micro Control Unit, Chinese name is Micro Control Unit) module is usually in a sleep state when the product is not working. Wake up the MCU module by generating an interrupt through the vibration switch. The vibration switch can be installed inside the product, and the switch cannot be seen from the outside, so it is particularly beautiful in appearance. But there is a defect in this kind of vibration switch, that is, vibration occurs under some non-standard vibration conditions, which wakes up t...

Abstract

The invention discloses a method, a system and a device of adjusting sensitivity of a vibration switch and belongs to the technical field of electronics. The method includes the following steps: when a microprogrammed control unit (MCU) receives interrupt signals of the vibration switch, counting vibration times of the vibration switch within a preset time, if vibration times of the vibration switch within the preset time period reach the preset time, enabling a MCU module to withdraw from a sleeping mode, and entering a main program; if the vibration times of the vibration switch within the preset time period are smaller than the preset time, and enabling the MCU module to keep the sleeping mode. The method of adjusting sensitivity of the vibration switch can adjust sensitivity of the vibration switch flexibly, and solve the problems that the sensitivity of the vibration switch is not adjustable and misoperation is caused due to interrupted instantaneity in the MCU module.

Description

technical field [0001] The invention belongs to the field of electronic technology, and in particular relates to a method, a system and a device for adjusting the sensitivity of a vibration switch by interrupting an MCU module. Background technique [0002] A vibration switch, also called a vibration sensor, is an electronic switch that can sense the magnitude of the vibration force and transmit the sensing result to the circuit device, and make the circuit start to work. Also known as a vibration switch, also known as a slide switch or a shaking switch, etc.; the names in the industry are generally divided into two categories, spring switches and ball switches. [0003] Vibration switches are mainly used in electronic toys, small household appliances, sports equipment and various anti-theft devices and other products. Vibration switches have become an indispensable electronic component in many electronic products because of their flexible and sensitive triggering. [0004...
