Abstract

The invention is an engine maintaining alarm apparatus, belonging to the engine maintaining technique. And it comprises MCU, MCU-connected vibration sensor detecting circuit, storage circuit, system clock circuit, power supply circuit, liquid display circuit, communication circuit, voice circuit, keyboard circuit and short message alarm circuit. And it can automatically prompt people to maintain engines according to the working hours of the engines without changing the original mechanical circuits to ensure the mechanical performance is not interfered and destroyed, and can real-timely monitor the operating states of the engines to remove hidden peril of the accident and prolong the engine service life.

Description

technical field [0001] The invention belongs to an engine repair and maintenance alarm prompting device. Background technique [0002] Most of the existing engines use the working hours of the engine as the basis for their repair and maintenance. Due to the harsh working environment of most mechanical equipment, the engine motorcycle hour counting instrument configured on it is prone to failure, resulting in failure to monitor the working hours of the engine. At the same time, due to the staff's lack of knowledge about engine repair and maintenance, even if the engine working hour meter works normally, it is easy to cause improper maintenance and maintenance of the engine, resulting in waste of repair and maintenance resources or reducing the service time of the engine. [0003] Engine failure and operation prompt instrument (Chinese invention patent: CN 1773238A) discloses a kind of engine failure and operation prompt instrument. Through the voice prompt, the user will be ...
