Problems solved by technology

The engine is equivalent to the heart of the mechanical equipment. Once there is a problem with the engine, the mechanical equipment cannot be used, and the price of repairing and replacing the engine is relatively expensive. Therefore, it is necessary to monitor the user status of the engine during use and be able to Relieve the crisis of the engine in time
[0003] At present, there are many engine diagnosis methods. These diagnosis methods only diagnose the engine after the engine has a problem. It still needs to repair or replace the engine, and it cannot prevent it.

Embodiment Construction

[0012] The present invention will be further described below in conjunction with accompanying drawing.

[0013] As shown in the figure, the present invention is a method for preventing engine temperature from being too high. The rotational speed sensor is installed on the output shaft of the engine, the temperature sensor is installed on the surface of the engine, the oil temperature sensor is installed inside the engine, and the controller is a single-chip microcomputer. The specific method is as follows:

[0014] 1) The speed sensor collects the engine speed in real time and sends it to the controller, the temperature sensor collects the engine temperature in real time, and sends it to the controller, and the oil temperature sensor collects the engine oil temperature in real time, and sends it to the controller;

[0015] 2) The controller compares the received real-time rotational speed value w with the internally stored rotational speed threshold w0, if w>w0, enter step (3),...

Abstract

The invention discloses a method for preventing engine temperature from being too high. By collecting the rotational speed, surface temperature and oil temperature of the engine, and judging whether the engine temperature is high through the logic judgment inside the controller, and then taking measures in time, such as reducing the rotational speed or Stop working and reduce the engine temperature to prevent the engine from being burned out, prolong the service life of the engine and reduce the cost of use.

Description

technical field [0001] The invention is specifically a method for preventing engine temperature from being too high, and belongs to the engine detection technology. Background technique [0002] As one of the core components of mechanical equipment, the maintenance and protection of the engine is very important. The engine is equivalent to the heart of the mechanical equipment. Once there is a problem with the engine, the mechanical equipment cannot be used, and the price of repairing and replacing the engine is relatively expensive. Therefore, it is necessary to monitor the user status of the engine during use and be able to Relieve the crisis of the engine in time. [0003] There are many engine diagnosis methods at present, and these diagnosis methods only diagnose the engine after the engine has a problem, but still need to repair or replace the engine, and cannot play a preventive role. Contents of the invention [0004] Aiming at the above-mentioned problems in the...
