When the turnout is pulled from a positioning position to a reverse position, the reverse position operation button FCA is pressed and switched on, the power supply of a coil 14 of the reverse position operation relay FCJ is switched on, the reverse position operation relay FCJ is excited and sucked up, after the reverse position operation relay FCJ is excited and sucked up, a self-closing circuit is switched on through a second group 6-10 of suction contacts of the reverse position operation relay FCJ, at the moment, the reverse position operation relay FCJ is required to be checked to show that the relay FBJ is in a falling state and is not pulled towards the positioning position, and simultaneously, the switching relay ZHJ is sucked up, after the switching relay ZHJ is sucked up, the self-closing is realized through the cooperation of a third group 7-11 of contacts of the reverse position operation button DCA and the normally closed contacts, the switching relay ZHJF is a reset relay of the switching relay ZHJ, the switching between the fixed position circuit and the reverse position circuit is realized by using a large current contact.

After the turnout is switched in place, the pulling power supply is disconnected through the contact of the automatic switch of the point switch of the external test, at the moment, if the contact is good and the contact resistance is in a reasonable range, the corresponding indicating relay is switched on, the indicating relay adopts the working voltage of direct current 110V, the indicating relay obtains the direct current working power supply through the current limiting resistor R and the parallel capacitor, the indicating circuit shows that the polarity of the power supply is consistent with the calibration polarity, the indicating lamp inside the relay is lightened, if the polarity of the power supply is inconsistent with the calibration polarity, the indicating relay is sucked up, the indicating lamp inside is turned off, the indicating circuit state is complete, the polarity of a field diode is reversed, and the point switch is timely searched.

The inverted position represents the excitation circuit of the relay FBJ: the reverse position shows that the coil 13 of the relay FBJ is communicated with a corresponding loop through 2-10 of the second group of suction contacts of the switching relay ZHJ → 1-9 of the first group of falling contacts of the reverse position control relay FCJ → 2-3 of the first group of suction contacts of the switching relay ZHJF → a pulling common line (X2) to send alternating current 110V power, the corresponding loop is communicated with the contacts in the switch machine, a special line (X3) → representing transformer alternating current 110V is connected through an external port terminal 3, and meanwhile the reverse position shows that the second group of suction contacts 6-10 of the relay FBJ is connected with a circuit of the indicator lamp system to turn on a yellow indicator lamp.
The preferred embodiment mainly comprises a representation transformer, a representation relay, a control unit, a rectification module, a power supply module, a remote control module and the like.
The working principle of the preferred embodiment is as follows:
the invention uses the direct current switch circuit as the blue book, on the premise of not changing the original circuit function, adds the contact resistance detection circuit for realizing the inspection of the internal contact of the motor, when the lead resistance of the automatic switch and each terminal in the switch is too large (more than 100 omega), the detection indicator lamp will turn off the lamp and not turn on the lamp. The input 220V alternating current power supply is converted into a pulling power supply for the turnout switch machine through the rectifying module, after the positioning operation button DCA is pressed down and switched on, the positioning operation relay DCJ relay excitation circuit is switched on, the positioning operation relay DCJ relay is sucked up, the motor direct current rectifying module is switched on through the third group 11-7 sucking up contacts of the positioning operation relay DCJ to send direct current pulling power supply for X4, and at the moment, the other pole power supply is matched with the falling contact of the relay repeater ZHJF through the first group 5-9 sucking up contacts of the positioning operation relay DCJ to be supplied with power for X1, so that turnout switching is realized. When the switch is in the reverse operation, the reverse operation button FCA is only needed to be pressed to connect the reverse operation relay FCJ and the switching relay ZHJ circuit, and the switch is switched to the reverse position by matching the reverse operation relay FCJ and the switching relay ZHJ circuit. When the turnout is in place, the contact of the switching relay ZHJ and the switching relay duplicate relay is used for switching on a corresponding representation relay circuit, the representation relay is sucked up, and corresponding representation is given.
