Method for effective control of numerical control

The sensor outputs an alternating signal. In order to effectively control the numerical control device, the portion of the alternating signal amplitude higher than the upper limit level UH and lower than the lower limit level UL is required to enter the amplifying circuit, and the amplifying circuit amplifies and sends the signal. Into the numerical control device, the numerical control device is put into operation. If the signal amplitude is within the UHUL range, the amplifying circuit must output a 0 level to put the numerical control device into a sleep state.

The alternating signal Ui outputted by the sensor is sent to the input end of the amplifying circuit, the output voltage UO of the amplifying circuit is sent to the numerical control device, and the four diodes V1V4 form a bridge circuit. Let Ui be a positive value, and the value of IF can only be greater than 0 or equal to 0.

The voltage amplification factor is: Au=UoUi=-IFRFRiIi=-(Ii-I2)RFRiIi=-RFRi(1-I2Ii), and only in the case of Ii>I2, the amplifier circuit can be effectively amplified, and the bridge is in an unbalanced state. . If Ii is less than I2, the bridge is in equilibrium, Au=0, and the numerical control device is in the sleep zone. When Ui is negative, when the bridge is balanced, only in Ui
