The 220V AC voltage is input from the power supply screen 3 and then subjected to power stabilization and filtering by UPS101 to power the equipment in the host. The indoor power supply is sent to the outdoors through the distribution board of the distribution cabinet 4 through the isolation transformer 102 to power the outdoor equipment such as the collection extension 5. There is a lightning protection module 103 on one side of the isolation transformer 102.

[0023] During operation, when the switch machine is in motion, the motor current changes. At this time, the continuous conversion resistance data during the movement of the switch machine is collected and transmitted back to the room to form a curve after the action is completed. Through this curve, the conversion force of the switch machine, the working condition of the turnout, etc. can be analyzed. Regardless of whether the switch machine is in motion or not, the data received from the conversion resistance sensor 203 is sent to the room for display. When the conversion resistance is low or high, the turnout may have a risk of blocking, and an alarm is issued to remind the staff to maintain the turnout.

[0024] The outdoor equipment includes a data collection extension 5 and various sensors, and the outdoor equipment is installed inside the trackside equipment; the sensors include: a gap sensor 201, a temperature and humidity sensor 202, a conversion resistance sensor 203, and a current sensor 204.
