Abstract

The invention discloses an explosive internal temperature field measuring device, and relates to the field of automatic testing. The explosive internal temperature field measuring device is composed of an STM32 central control host machine, a plurality of slave machines for temperature acquisition and a carbon fiber rod. Multi-point measurement of the internal temperature of the explosive can be completed, temperature measurement points are flexibly positioned, the number of temperature measurement points is flexibly configured, measurement interference caused by wiring is avoided, meanwhile, the collected temperature value is sent to the upper computer, and thermal accumulation damage prediction of the explosive is conducted on the temperature value on the upper computer through a BP neural network improved through a firework algorithm. The device has the advantages of being small in size, flexible in sensor positioning, flexible in sensor point number and group number configuration, capable of avoiding simulation line measurement errors and high in prediction precision.

Description

technical field [0001] The invention belongs to the field of automatic testing and relates to a device for measuring the internal temperature field of explosives. Background technique [0002] During the long-term storage of explosives, the slow physical and chemical changes inside the powder column will generate a certain amount of heat. Under the condition of sealed storage, the heat will not be released in time to generate heat accumulation. When the heat accumulation reaches a certain level, the performance of explosives will be affected. Indicators change, affecting the life cycle of the explosive itself. In order to obtain the relationship between the explosive performance index and the temperature, the influence of explosive thermal damage on the explosive performance parameters is further studied. Therefore, first of all, it is necessary to monitor the temperature field inside the powder column, and flexibly locate the sensor in the internal position of the powder c...
