Abstract

The invention relates to a reliability detecting method for a multi-channel power transmission device. The reliability detecting method is achieved through a reliability detecting system. The reliability detecting system comprises a control computer, a multifunctional measuring unit, a multiplexing module, a junction device and an adjustable direct current power source. The method is used for detecting the reliability of the dynamic contact resistance of the multi-channel power transmission device of a high-precision inertia instrument, whether the power transmission device makes good contact or not is judged according to reliability detecting data, the installation of the power transmission device is further adjusted, and the purpose of accurately transmitting signals is achieved. By means of the method, quick and accurate measuring and reliability detecting on the small dynamic resistance of a multiplexer channel of the power transmission device are achieved, and the adopted reliability detecting system is high in integration level, measuring precision and automation degree, easy to operate, safe and reliable.

Description

technical field [0001] The invention relates to the field of debugging and detection of inertial devices, in particular to a reliability detection method of a multi-channel power transmission device, which realizes fast and accurate measurement of multi-channel resistance. Background technique [0002] When the inertial instrument is working, the brush of the power transmission device rotates relative to the conductive rod. During the rotation, the signal transmission between the internal working components and the peripheral circuit is realized through the cable. In order to ensure the normal operation of the instrument, very high requirements are put forward for the power transmission device. The contact between the brush and the conductive rod must be reliable during the rotation process, and there must be no disconnection or poor contact. The traditional dynamic contact resistance measurement system cannot satisfy the multi-channel real-time reliability detection of the ...
