Problems solved by technology
The simple test cable used before was made by the factory around 2000, and it can only test individual models of hover meters, but cannot test all four existing models of hover meters; on the other hand, using test cables requires Connect one end of each cable to the corresponding hover meter connector pin, and connect the other end to the power supply or signal source, which is very inconvenient to operate
[0005] The evaluation found that although the original test equipment and process methods did not affect the product repair test delivery, it would also cause easy wiring errors, a greater quality and safety risk, and lower work efficiency

The invention discloses a hover meter comprehensive test device, and relates to the field of hover meter testing. The hover meter comprehensive test device comprises a shell and an electrical module integrated in the shell, the electrical module comprises a working voltage supply circuit and a signal source which are connected in parallel, and the working voltage supply circuit is sequentially connected with a hover meter selection control circuit and an alarm detection circuit in series. A positive and negative signal selection control circuit, a signal voltage adjusting circuit and a three-axial speed selection control circuit are sequentially connected to the signal source in series, and the hover meter selection control circuit, the alarm detection circuit and the three-axial speed selection control circuit are connected with the same hover meter interface circuit; and the working voltage supply circuit and the signal voltage adjusting circuit are connected with the same signal voltage measuring circuit. According to the test device, single-piece performance testing of four types of hover meters is realized, and the defects of complex connection lines, inconvenience in operation and certain potential safety hazards during hover meter testing are overcome.
Description
Technical field [0001] The present invention relates to the field of hovering table tests, and more particularly to a hovering table integrated test device. Background technique [0002] The hovering form is composed of a header and control circuit, which is used to support the Doppler radar, which will be proportional to the helicopter three axial speed input from Doppler radar, sampling, processing, helicopter entering the suspension When stopping, out of the hover or a hover state, the longitudinal speed, lateral speed, and vertical speed of the helicopter coordinate system are displayed on the head. There are also two alarms to display the status of the system, the memory the alarm displays the memory state, and the power security flag displays the power failure state. [0003] At present, there is a HI hover table, ZXT-1 hovering table, 777 hover table, XTB-1 hover table, 777 hover, XTB-1 hovering table, and the tactics of hover tables is required to carry out helicopters.
