The intelligent initiating explosive device equivalent device comprises high voltage timing sequence input terminals, low voltage timing sequence input terminals, an equivalent device high voltage input level circuit, an equivalent device low voltage input level circuit, a high voltage and low voltage switching circuit, a state indication lamp, an input / output (I / O) control circuit, a 5V power supply, a 24V power supply, a high and low pulse width timing sequence measurement circuit, an optoelectronic isolation digital input and output module, a 104 bus, a personal computer (PC) main machine and a PC 104 main machine power supply. The pulse timing sequence signal measurement method includes initializing; clamp board self-detection: executing the next step if self-detection is finished, otherwise repeating execution of self-detection; high and low voltage self-detection: returning to clamp board self-detection if high and low voltage self-detection is not finished, otherwise conducting high and low voltage detection; and displaying and storing data after high and low voltage detection. The intelligent initiating explosive device equivalent device and the pulse timing sequence signal measurement method are used in intelligent initiating explosive device equivalent device manufacturing.

Description

technical field [0001] The invention belongs to the technical field of detection and management of power supply paths of pyrotechnic products, and relates to the detection and processing of time series signals, FPGA technology and virtual instrument application technology. Background technique [0002] As the requirements for missile performance become higher and higher, the number of pyrotechnics loaded on the missile is also increasing, usually including engine ignition, inter-stage separation, wing expansion, tail expansion, etc., and its state directly affects the missile. Flight conditions and target hit rate. Therefore, the reliability of the pyrotechnics on the bomb and the corresponding power supply path and timing command (pulse timing) is very important. Before the missile is launched, it should be tested and checked, especially when the missile is stored for a long time after it is installed. more stringent testing. At present, before the launch of the pyrotechn...
