Fast multi-path temperature sensor encoding system and method

Abstract

The invention discloses a fast multi-path temperature sensor encoding system and method. The encoding system comprises a plurality of temperature sensors, a temperature sensor bus, a PC, and an insulation heat conduction strip which fixes the temperature sensors. The insulation heat conduction strip is fixed to a temperature difference fixture. The bus ports of the temperature sensors are connected to a wireless transmission acquisition board which is in wireless communication with a host computer. According to the system and the method, the principle that a temperature difference is formed by heat conduction in heat conduction strip single end heating is used, the temperature sensors are encoded according to high and low temperatures, a problem that multiple paths of temperature sensors can not be encoded on a bus PCBA in batch production is solved, and the efficiency is very high. A temperature measurement network formed by 1024 paths of temperature sensors is practical.

Description

technical field [0001] The invention is a fast multi-channel temperature sensor coding system and method, which can realize up to 1024 fast sensor coding functions, and is applied to occasions requiring multi-channel temperature measurement such as flexible direct current transmission capacitor packs and electric vehicle batteries. Background technique [0002] In recent years, with the advancement of technology and the support of national policies, smart grids and new energy vehicles have developed rapidly, and the functional requirements of corresponding components are also constantly changing. Capacitor packs used in flexible DC power transmission have begun to use film capacitors with longer life and better performance. Large-capacity capacitor packs generally consist of hundreds or even thousands of capacitor cores connected in series and parallel. During use, the temperature of the capacitor core is generally not much different. If one of the capacitor cores is abnorm...

AI Technical Summary

Problems solved by technology

During use, the temperature of the capacitor core is generally not much different. If one of the capacitor cores is abnormally heated, the capacitor pack should be removed from the system immediately, otherwise there will be a huge safety hazard

The battery pack, which is also a key component of electric vehicles, is similar in structure to the above-mentioned capacitor pack, and the uneven distribution of internal temperature will also bring safety risks
