Title The design of storage measurement systement in explosion temperature field
Abstract
The temperature measurement and research on temperature distribution of explosion field provide the basis for explosives and ammunition on the power of evaluation and analysis,is of great significance
A bomb of certain for explosion temperature field has the characteristics such as large area,high temperature,rapid changes,and with high speed and high pressure air flow.And the need for test of vacuum explosions and internal explosion.so application of conventional methods of temperature measurement is difficult.Against that background, research on storage test technology of transient temperature for explosive field based on thermocouple is carried out.
The paper provides a design procedure of temperature measurement system of memory type for explosion temperature field,including host computer and hardware circuit. The hardware structure of the hardware circuit system consists mainly of WRE thermocouple,signal dealing module,the CPU master control module,power module,memory module,communication interface and external auxiliary circuit and so on.The host computer software is compiled by adopting LABVIEW
