Description

Multi-engine temperature online monitoring system based on wireless technology

Technical Field

The motor performance of the utility model is very strong whether it is a civil vehicle or an military vehicle. Generally, a gasoline engine and a diesel engine, collectively referred to as an engine, may be equipped for the vehicle according to its usage object and use. For the research of the engine, scientific research personnel never stop working, wherein the temperature of the engine is one of important factors influencing the performance of the engine, and the engine oil is deteriorated, the lubricating effect is reduced, and the abrasion of parts is aggravated due to overhigh temperature of the engine; the mechanical property of the metal material is obviously reduced, and deformation and damage occur; the air charging quantity of the cylinder is reduced, so that the power of the engine is reduced; the engine can be burned seriously. Similarly, the temperature of the gas entering the cylinder is low due to the over-low temperature of the engine, so that the combustion efficiency is influenced, the power of the engine is reduced, and the fuel consumption is increased; the viscosity of the engine oil is increased, poor lubrication is caused, and the abrasion of parts is aggravated; the engine is difficult to start, the metal abrasion is intensified, and the damage of the engine is accelerated. Therefore, the engine temperature directly affects the engine performance and thus the vehicle maneuverability. In order to further study the influence of temperature on the performance of an engine and make the study more valuable, when the temperature of the engine is collected, the vehicle is started, the temperature of the engine in the started vehicle is monitored, and the engine and a vehicle body are not separated and are monitored independently. The obtained engine temperature monitoring data has great application value and research significance.

At present, engine temperature monitoring methods are more, and there are three main methods which are more in application, namely a thermometer monitoring method, a sensor monitoring method and an infrared imaging monitoring method. The three methods have obvious defects when being applied to monitoring the temperature of the engine, and the thermometer monitoring method has large error and is not suitable for being applied to monitoring the temperature; the sensor monitoring method has the advantages that the wiring of an engine mounted on a vehicle body is very complex, a mobile power supply needs to be configured independently, the monitoring time is limited, and the data processing capacity is very limited; the infrared imaging detection method is not suitable for engine temperature monitoring mounted on a vehicle body because an engine is mounted on a vehicle body, an operation space is very small, and an infrared imaging device cannot photograph every part of the engine. Based on the above problems, it is necessary to invent a brand-new engine temperature online monitoring system based on wireless technology, which can effectively solve the disadvantages caused by the above three temperature monitoring methods.
