Embodiment Construction

[0010] Such as figure 1 As shown, the detection device of the nuclear power seismic instrument system is composed of DSP, single-chip microcomputer, DDS signal generator, AD converter, liquid crystal display, keyboard, temperature probe, infrared communication module and input and output interfaces, and can detect various parameters of the nuclear power seismic instrument system The way is as follows:

[0011] (1) Earthquake acceleration trigger threshold verification: The input and output interfaces described in this device have three differential voltage signal output channels. Connect the acquisition module of the seismic instrument system to the corresponding channel of this device, select the test item "trigger threshold value verification" through the keyboard, set the threshold value and frequency, and the single-chip computer controls the DDS signal generator to output voltage signals, so that the signal amplitude is within the set value. The threshold floats slowly; ...

Description

technical field [0001] The invention relates to a detection device for a nuclear power seismic instrument system. technical background [0002] The reliability of the operation of the nuclear power plant seismic instrument system is directly related to the safe operation of the nuclear power plant. Therefore, it is necessary to regularly test and verify the parameters of the system. The detection of the seismic instrument system is a very cumbersome task, which needs to detect many important parameters of the system. The existing detection methods adopt a single detection method, which separately detects the system frequency response, acceleration trigger threshold, surface radiation temperature of system components during operation, and For the calibration inspection of strong motion instruments, multiple testing devices need to be carried during the test process, which takes up a lot of on-site space; because the devices are independent of each other, the wiring is complic...
