Embodiment Construction
[0013] The present invention will be further described in detail below in conjunction with the accompanying drawings and preferred embodiments.
[0014] according to figure 1 As shown, the preferred embodiment of the present invention is directed to a transmission device for an analog accelerometer output signal output as a current signal. The device includes four parts: a power supply, a voltage follower circuit, a differential processing circuit and a twisted pair.
[0015] The voltage follower circuit is composed of a first resistor R1 and a first operational amplifier N1. The first resistor R1 is an accelerometer sampling resistor. One end is connected to the positive input terminal of the first operational amplifier N1, and the other end is connected to the power supply ground. The resistance value Depending on the use range of the accelerometer, the positive power terminal of the first operational amplifier N1 is connected to the positive output terminal of the power sup...
