Embodiment Construction
[0015] The present invention will be further described below in conjunction with accompanying drawing.
[0016] figure 1 The reference number 1 is the strain gauge axial power detection module including packaged strain gauges, rotational speed sensor, and signal conditioning module. Pin 3 of the strain gauge is the power inlet, pin 4 is grounded, pins 1 and 2 are connected to the IN1+ and IN1- input interfaces of the signal conditioning circuit, pins 5 and 6 of the speed sensor are connected to the IN2+ and IN2- input of the signal conditioning circuit The interface is connected. The output terminals O1+, O1-, O2+, O2- of the signal conditioning circuit are respectively connected to the input interfaces IN1+, IN1-, IN2+, IN2- of the wireless transmitting module.
[0017] figure 1 The point-to-point data transmission module described in No. 2 includes a signal transmitting and signal receiving module, two input and output. VCC is the power inlet, and GND is grounded. The I...
