A remote measurement system and method for internal combustion engine piston temperature based on wireless charging

Abstract

The invention discloses a wireless charging-based internal combustion engine piston temperature telemetry system and method, belonging to the technical field of engine testing, which includes a wireless charging device, a temperature telemetry device, a first packaging box and a second packaging box, wherein the wireless charging device includes A transmitting coil, a transmitting module, a receiving coil and a receiving module, and a temperature telemetry device including a rechargeable battery, a signal processing unit, a thermocouple and a host computer. Corresponding working methods are also provided. The present invention supplies power to the transmitting coil through the external power supply and the transmitting module, and then generates AC current in the receiving coil through electromagnetic induction, and converts the AC current into DC through the receiving module and supplies it to the rechargeable battery to realize the electromagnetic induction wireless charging and charging of the telemetry system. Continuous power supply, high energy efficiency, and simple structure; the temperature telemetry device transmits temperature information to the host computer through wireless communication technology, completely realizing the wireless measurement of internal combustion engine piston temperature.

Description

technical field [0001] The invention belongs to the technical field of engine testing, and more specifically relates to a remote measurement system and method for piston temperature of an internal combustion engine based on wireless charging. Background technique [0002] The sixth phase of the National Motor Vehicle Pollutant Emission Standard is about to be implemented. In order to meet the strict internal combustion engine emission regulations, the degree of strengthening of the internal combustion engine is getting higher and higher, which will inevitably lead to an increase in the temperature of the heated parts of the internal combustion engine, especially the heat load of the piston. The internal combustion engine piston is subjected to the worst working conditions of the whole machine, and its working temperature has always been the focus of scholars' research. However, due to the high temperature and harsh working environment of the internal combustion engine piston...

Problems solved by technology

However, this power supply method needs to install an induction coil under the body and the piston. Only a larger electromagnetic induction coil can provide enough power. The change to the body is relatively large, and it is only suitable for power supply for measuring the temperature of the piston of a larger internal combustion engine.
