[0002] The reliability and stability of turnout operation play a vital role in the safety and smoothness of driving, and is one of the important equipment in the field of rail transportation. The point rail and the center rail are responsible for changing the direction of train operation. Their importance is self-evident. They are important parts of the steel rail turnout. In addition, the node aging of the switch machine is related to whether the gap position is in place, as well as parameters such as the conversion force. Therefore, it is necessary to effectively monitor the nodes of the turnout switch machine.

[0003] Traditional node aging maintenance relies entirely on on-site inspection and analysis by maintenance personnel, and the maintenance workload is very large. However, with the development of technology, there are currently gap monitoring sensors, such as CN218847119U, a gap monitoring sensor in the ZD6 switch machine: it can not only prevent indication failures caused by turnout quality problems in advance, but also effectively improve the efficiency of gap inspection and gap adjustment by operating and maintenance personnel, and can detect hidden dangers in time. There are also devices based on image recognition technology to monitor and judge the gap position to replace manual maintenance, such as CN219627814U, a switch machine gap video monitor: it has dynamic shooting capabilities to take a group of dynamic photos of the alignment process of the indication rod gap and the inspection column, and perform image recognition analysis on this group of photos to determine whether the alignment process of the turnout point rail and the basic rail is stable and smooth, so as to detect safety hazards early.

[0004] However, the above devices are all single-machine monitoring and cannot systematically monitor each turnout machine node. Summary of the invention

[0005] In order to solve the above problems, it is necessary to provide a turnout switch node aging analysis data acquisition device and a monitoring system that can systematically monitor each turnout switch node.

[0009] The second aspect of the utility model provides a switch node monitoring system, including a communication extension, a station machine, and the switch node aging analysis data acquisition device; each switch node is provided with a switch node aging analysis data acquisition device; the acquisition extensions of multiple switch node aging analysis data acquisition devices are connected to a communication extension, and the station machine is connected to multiple communication extensions in network communication, so as to transmit the data collected by all the switch node aging analysis data acquisition devices to the station machine through the communication extension.

[0010] Based on the above, the collection extension and the communication extension use two-wire broadband PLC communication, the communication frequency is set at 2-28Mhz, and OFDM modulation technology is used for modulation; or the collection extension and the communication extension use VDSL communication, and the communication frequency is set above 50HZ.

[0011] Based on the above, the data collection extension is installed in an existing outdoor turnout signal equipment box, and the casing is made of cast aluminum with an IP54 protection grade.

[0012] Based on the above, the communication extension is mounted with the collection extensions of no less than 20 turnout machine nodes; when the transmission distance is not more than 500m, the communication extension is directly connected to the station machine for communication; if the transmission distance is more than 500m, the communication extension is directly connected to the station machine for communication through a relay box with PLC carrier communication and VDSL communication functions; the communication transmission distance between the communication extension and the station machine is not more than 6Km, and the bandwidth speed limit is 2Mbps.

[0013] Based on the above, the station machine adopts an industrial control computer.
