Summary of the invention
The present invention aims to provide the detecting device integrated of a kind of nuclear and earthquake instrument system, and it is single to be used to solve existing detection method, carries inconvenience, and it is big to take up room, and detects problems such as implementing complexity.This device has following significant advantage:
1. with three important parameters of nuclear and earthquake instrument system: the frequency response test of the verification of seismic acceleration activation threshold value, acquisition channel and strong-motion instrument assembly are demarcated response test work and are integrated in one, and have simplified test process and testing apparatus greatly.
2. this device is provided with the DDS signal generating module, DSP, single-chip microcomputer, AD modular converter, wireless temperature probe, wireless communication module, signal input output interface, LCD and keyboard; The DDS signal generating module links to each other with DSP with AD modular converter, single-chip microcomputer; LCD links to each other with single-chip microcomputer with keyboard; The wireless temperature probe links to each other with single-chip microcomputer by wireless communication module.
The system integration digital frequency synthesizer (DDS) signal generating module, can send the interchange and the direct current signal of ultra-low frequency sinusoidal signal and other requirements very flexibly, carry out threshold triggers check test and acquisition channel frequency sound test.
4. input signal and output signal can directly be gathered by digital signal processor (DSP) control AD modular converter in real time, and the result is presented on the LCD.
5. the radiation temperature when adopting the wireless telecommunications thermal module of band sucker to measure the earthquake instrument system assembly operating, conveniently moving can be adsorbed on any surface of assembly; Because means of communication is an infrared mode, can not produce electromagnetic interference (EMI) simultaneously to equipment operation.
