Problems solved by technology

[0004] The design of the gyro measurement and control circuit usually puts the meter, signal processing module, and test pins on the same circuit board, but the welding and disassembly of the gyro is very troublesome. When there are a large number of meters that need to be tested At the same time, the test efficiency of such a circuit board design scheme is very low, and it is not convenient for the test of key signals of a large number of gyroscopes and the debugging of the board.

Abstract

The invention relates to a micro silicon gyroscope measuring and control device based on gauge head plate separation. The micro silicon gyroscope measuring and control device comprises a gauge head plate 1, a first connector 2, a shielded wire 7, a second connector 3, a signal processing board 4, a power supply pin 5 and a key test signal pin 6 which are connected in sequence. When micromechanical silicon gyroscopes in large batch need to be tested, a gauge head does not need to be replaced again each time, and only the gauge head plate needs to be replaced, so as to facilitate testing of key signals of the large-batch gyroscopes and plate debugging.

Description

technical field [0001] The invention relates to a gyro measurement and control device, in particular to a silicon micro gyro measurement and control device based on the separation of the meter head plate. Background technique [0002] Silicon micro gyroscope is a kind of sensor used to measure the attitude or rotational angular velocity of moving objects, and it plays a huge role in both military and civilian applications. Silicon micro-angular rate sensor has the advantages of small size, light weight, high reliability, low cost, mass production, easy integration with electronic circuits, etc. Equipment and other military and civilian fields have a wide range of applications. [0003] The structure diagram of the silicon micro gyroscope as the basis of this patent is as follows figure 1 Shown is a typical Z-axis Coriolis gyroscope. The direction of the X-axis is its driving axis, and after cooperating with the driving interface circuit, an oscillation loop is formed to p...
