Abstract

The invention belongs to the technical field of aerospace measurement and control, and discloses an index tester of inertial navigation equipment. The tester comprises an industrial personal computer, a data acquisition card, a signal conditioning circuit board and testing software, wherein the data acquisition card is arranged in a PCI (Peripheral Component Interconnection) slot of the industrial personal computer and is in communication with the industrial personal computer through a PCI bus so as to convert an analog signal into a digital signal; the signal conditioning circuit board is arranged in an ISA (Industry Standard Architecture) slot of the industrial personal computer and is in communication with the industrial personal computer through an ISA bus; an external line of the signal conditioning circuit board is connected with an electronic circuit board to be tested to finish reduction of a test signal; the testing software is installed on the industrial personal computer; the states of an indicator lamp on the electronic circuit board are recorded and counted, the voltage value and the frequency value of a detection hole are measured, and whether the electronic circuit board is normal is judged according to the measured voltage value and frequency value and the state of the indicator lamp. The index tester has the advantages of high testing accuracy, small error, convenience in operation, short testing period and small workload.

Description

technical field [0001] The invention relates to the technical field of aerospace measurement and control, in particular to an index tester for inertial navigation equipment. Background technique [0002] Inertial navigation equipment is widely used in large surface ships. In order to grasp its working status, it is necessary to carry out index tests frequently in daily maintenance. Since the inertial navigation equipment is composed of several plug-in boards, each plug-in board has a detection hole or an indicator light at the front end, and the detection hole will output the detection hole waveform in real time, and the detection hole waveform is the test signal. Normal, dark is abnormal, so you only need to observe the indicator light and measure the test signal output by the detection hole, you can fully grasp the working status of each circuit board, and then judge the working status of the whole machine. [0003] Because a single set of inertial navigation equipment in...
