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.

Abstract

The invention discloses an internal combustion engine piston temperature remote-measuring system based on wireless charging and a method, and belongs to the technical field of engine testing. The system comprises a wireless charging device, a temperature remote-measuring device, a first packaging box and a second packaging box, wherein the wireless charging device comprises a transmitting coil, atransmitting module, a receiving coil and a receiving module; and the temperature remote-measuring device comprises a rechargeable battery, a signal processing unit, a thermocouple and an upper computer. The invention also provides a corresponding working method. Power is supplied for the transmitting coil through an external power supply and the transmitting module, and then alternating current is generated in the receiving coil through electromagnetic induction, current is provided for the rechargeable battery after alternating current is converted into direct current through the receiving module, wireless charging and continuous power supply of electromagnetic induction for the remote-measuring system are realized, the energy efficiency is relatively high, and the structure is simple; and the temperature remote-measuring device is used for transmitting temperature information to the upper computer through a wireless communication technology, and the temperature measurement of an internal combustion engine piston is wireless.

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...
