[0077] Concrete Example: Coarse Detector Anomalies
[0078] When the CCD sensor and cable meet certain design specifications, the rough detector fault can be judged through the online detection of the photoelectric tracking equipment. CCD sensors and cables for testing. First initialize the system, preset system parameters, start taking pictures, and acquire pictures from the CCD sensor; select the cable test, transmit the test signal, obtain the reflected signal, eliminate the cross term of the signal, and then perform correlation calculation to obtain the cable If the CCD sensor can obtain images, but the cable is faulty, it can be preliminarily concluded that the connection cable of the CCD sensor is faulty. If the relevant waveform of the faulty cable is as follows Figure 7 As shown, the cable has an open circuit fault, and the fault location is calculated; if the relevant waveform of the faulty cable is as follows Figure 8 As shown, the cable has a short-circuit fault...

The invention discloses a test system and method for a photoelectric tracking device based on LabVIEW. The test system comprises an upper computer, a signal acquisition module, a signal generation module, a sensor test module and a cable test module, wherein the upper computer is electrically connected with the signal acquisition module and the signal generation module. The signal acquisition module is connected with the sensor test module, the cable test module is respectively connected with the signal acquisition module and the signal generation module through a T-shaped BNC joint, and the test system is used for testing and judging a sensor and a cable of the photoelectric tracking equipment, reducing the fault range and removing faults. The invention has the beneficial effects that the test is efficient and accurate, the test efficiency can be improved, and manpower and time are saved; the modules do not need to be disassembled, testing can be directly carried out through the testing system, and the technical requirement for maintenance personnel is low; therefore, the operation is convenient.
Description
technical field [0001] The invention relates to the field of fault testing of photoelectric tracking equipment, in particular to a testing system and method for photoelectric tracking equipment based on LabVIEW. Background technique [0002] In photoelectric measurement equipment, photoelectric telescope and laser communication system, photoelectric tracking equipment is required. Under the guidance of infrared warning equipment, photoelectric tracking equipment completes the tracking through the equipped TV, infrared detector, laser rangefinder and its processing unit. The long-distance capture, stable extraction and distance measurement of the target can complete the high-precision and stable tracking of the target under the control and management of the intelligent management unit and the tracking control unit of the tracking device. As the technical indicators such as measurement accuracy are getting higher and higher, the requirements for capture, tracking and aiming ar...
