If setting back after the time.
Device the most according to claim 8, it is characterised in that described force-balanced accelerometer is specifically for according to institute
Stating four upsets that controller carries out, to produce the first output signal, the second output signal, the 3rd output signal and the 4th respectively defeated
Go out signal.
Device the most according to claim 9, it is characterised in that described processor specifically for:
Respectively obtain described according to described first output signal, the second output signal, the 3rd output signal with the 4th output signal
The time-history curves of three passages；
Whether the time-history curves to described three passages occurs that the situation of square wave judges respectively, obtains the polarity of each passage
And direction, particularly as follows:
If after obtaining described first output signal, there is downward square wave in described time-history curves, it is thus achieved that described second output letter
After number, there is square wave upwards in described time-history curves, it is thus achieved that after described 3rd output signal and described 4th output signal, described
Time-history curves occurs without square wave, it is determined that the polarity of this passage is just, direction is X-axis positive direction；
If after obtaining described first output signal, there is square wave upwards in described time-history curves, it is thus achieved that described second output letter
After number, there is downward square wave in described time-history curves, it is thus achieved that after described 3rd output signal and described 4th output signal, described
Time-history curves occurs without square wave, it is determined that the polarity of this passage is negative, and direction is X-axis negative direction；
If after obtaining described first output signal and described second output signal, described time-history curves occurs without square wave, it is thus achieved that
After described 3rd output signal, there is downward square wave in described time-history curves, it is thus achieved that after described 4th output signal, described time-histories
There is square wave upwards in curve, it is determined that the polarity of this passage is just, direction is Y-axis forward；
If after obtaining described first output signal and described second output signal, described time-history curves occurs without square wave, it is thus achieved that
After described 3rd output signal, there is square wave upwards in described time-history curves, it is thus achieved that after described 4th output signal, described time-histories
There is downward square wave in curve, it is determined that the polarity of this passage is negative, and direction is Y-axis negative sense；
If obtaining described first output signal, described second output signal, described 3rd output signal and described 4th output
After signal, all there is downward square wave in described time-history curves, it is determined that the polarity of this passage is just, direction is Z axis forward；
If obtaining described first output signal, described second output signal, described 3rd output signal and described 4th output
After signal, all there is square wave upwards in described time-history curves, it is determined that the polarity of this passage is negative, and direction is Z axis negative sense；
Polarity according to described three passages and direction determine polarity and the direction of described force-balanced accelerometer.
