Abstract
The invention discloses a method for preventing the temperature of an engine from being overhigh, which judges whether the temperature of the engine is higher or not by collecting the rotating speed, the surface temperature and the oil temperature of the engine and logically judges through the inside of a controller, and then measures are taken in time, such as reducing the rotating speed or stopping working, to reduce the temperature of the engine so as to prevent the engine from being burnt out, prolong the service life of the engine and reduce the use cost.
Description
Technical Field
The invention particularly relates to a method for preventing an engine from being overhigh in temperature, and belongs to the engine detection technology.
Background
The engine is one of the core components of mechanical equipment, and the maintenance and the protection of the engine are very important. The engine is equivalent to the heart of mechanical equipment, once the engine has problems, the mechanical equipment cannot be used, and the price for maintaining and replacing the engine is expensive, so that the state of a user of the engine needs to be monitored in the using process, and the crisis of the engine can be timely relieved.
At present, a plurality of engine diagnosis methods exist, the engine diagnosis methods only diagnose the engine after the engine has problems, the engine still needs to be repaired or replaced, and the prevention effect cannot be achieved.
Disclosure of Invention
Aiming at the problems in the prior art, the invention provides a method for preventing the temperature of the engine from being overhigh, which can prevent the engine from faults, reduce the maintenance times and cost of the engine and prolong the service life of the engine.
The invention discloses a method for preventing overhigh temperature of an engine, which comprises the following steps:
1) the engine oil temperature sensor acquires the engine oil temperature of the engine in real time and transmits the engine oil temperature to the controller;
2) the controller compares the received real-time rotating speed value w with an internally stored rotating speed threshold value w0, if w is larger than w0, the step (3) is carried out, if w is smaller than or equal to w0, the engine is judged to be normal, and the rotating speed sensor continues to detect the real-time rotating speed w of the engine;
3) the controller compares the received real-time temperature value t with an internally stored temperature threshold value t0, if t is greater than t0, the step (4) is carried out, if t is less than or equal to t0, the engine is judged to be normal, and the temperature sensor continues to detect the real-time temperature t of the engine;
4) the controller compares the received real-time engine oil temperature value f with an engine oil temperature threshold value f0 stored in the controller, if f is larger than f0, the temperature of the engine is judged to be too high, and the controller controls the motor to stop working until t is less than or equal to t 0; if f is less than or equal to f0 and w is more than w0, the temperature of the engine is judged to be high, and the rotating speed of the engine is controlled to be reduced until t is less than or equal to t0 and w is less than or equal to w 0.
Compared with the prior art, the method and the device have the advantages that the rotating speed, the surface temperature and the oil temperature of the engine are collected, the logical judgment in the controller is carried out, whether the temperature of the engine is high or not is judged, and then measures are taken in time, such as reducing the rotating speed or stopping working, and reducing the temperature of the engine, so that the engine is prevented from being burnt out, the service life of the engine is prolonged, and the use cost is reduced.
Drawings
Fig. 1 is a schematic view of the overall structure of the present invention.
Detailed Description

As shown in the figure, the method for preventing the temperature of the engine is characterized in that a rotating speed sensor is arranged on an output shaft of the engine, a temperature sensor is arranged on the surface of the engine, an oil temperature sensor is arranged in the engine, a controller is a single chip microcomputer, and the specific method comprises the following steps:
1) the engine oil temperature sensor acquires the engine oil temperature of the engine in real time and transmits the engine oil temperature to the controller;
2) the controller compares the received real-time rotating speed value w with an internally stored rotating speed threshold value w0, if w is larger than w0, the step (3) is carried out, if w is smaller than or equal to w0, the engine is judged to be normal, and the rotating speed sensor continues to detect the real-time rotating speed w of the engine;
3) the controller compares the received real-time temperature value t with an internally stored temperature threshold value t0, if t is greater than t0, the step (4) is carried out, if t is less than or equal to t0, the engine is judged to be normal, and the temperature sensor continues to detect the real-time temperature t of the engine;
4) the controller compares the received real-time engine oil temperature value f with an engine oil temperature threshold value f0 stored in the controller, if f is larger than f0, the temperature of the engine is judged to be too high, and the controller controls the motor to stop working until t is less than or equal to t 0; if f is less than or equal to f0 and w is more than w0, the temperature of the engine is judged to be high, and the rotating speed of the engine is controlled to be reduced until t is less than or equal to t0 and w is less than or equal to w 0.
The method effectively prevents the engine from being damaged due to overhigh temperature in the working process, prolongs the service life of the engine and reduces the use cost.
