Description

Technical Field

[0001] The utility model relates to the technical field of rail transportation, in particular to a turnout health monitoring system. Background Art

[0002] With the rapid development of the subway network, as the main force of the public transportation system, the subway operating mileage has increased dramatically, and the driving intervals have become shorter and shorter, which has put forward high requirements for the maintenance of subway system equipment. At present, due to the limited talent training system and on-site maintenance personnel, especially the insufficient number of maintenance personnel with considerable professional knowledge and maintenance experience, the accuracy of fault judgment and processing speed are difficult to meet the needs of on-site maintenance. As the equipment with the highest failure rate in the signal system, the state of the turnout will directly affect the driving safety and operation efficiency. How to ensure the healthy and stable operation of the equipment is particularly important. At present, the turnout equipment is only maintained in good condition through periodic maintenance and fault repair such as biweekly inspection, monthly inspection, and annual inspection. The maintenance workload is huge, and it is impossible to detect the hidden dangers of equipment failure or deterioration trends in advance and eliminate them in time. It can only passively deal with the occurrence of various failures.

[0003] The health status of the turnout can be reflected by its operating condition. By accurately monitoring the turnout indication gap, conversion resistance, and rail displacement, the turnout operating condition can be effectively and comprehensively understood. The health status of the turnout can be reflected by the operating condition indicators. Maintenance personnel can carry out targeted maintenance on turnouts with poor health conditions, thereby avoiding turnout failures and reducing the labor intensity of maintenance operations.

[0004] At present, in the field of turnout monitoring, independent data acquisition extensions are used to collect the working conditions of on-site equipment for turnout gap, conversion resistance, and rail displacement, which results in an increase in the number of equipment on the turnout site, difficulty in process layout, and difficulty in later maintenance. The maintenance site needs a turnout health monitoring system that integrates turnout gap, conversion resistance, rail displacement, and external locking oiling with high integration and reasonable equipment layout. The existing gap monitoring uses image recognition technology to identify the edge position change of the gap of the indicator rod and obtain the gap displacement value, but the gap value is the gap width value formed by the inspection column falling into the groove of the indicator rod. The existing recognition method cannot reflect the change in the gap value caused by the displacement change of the inspection column itself.

[0005] Based on this, the utility model designs a turnout health monitoring system to solve the above-mentioned problems. Utility Model Content

[0006] The purpose of this section is to summarize some aspects of the embodiments of the utility model and briefly introduce some preferred embodiments. Some simplifications or omissions may be made in this section and the abstract of the specification and the name of the utility model to avoid blurring the purpose of this section, the abstract of the specification and the name of the utility model, and such simplifications or omissions cannot be used to limit the scope of the utility model.

[0007] Therefore, the purpose of the utility model is to provide a turnout health monitoring system that can solve the current problems in the field of turnout monitoring, such as the collection of turnout indication gap, conversion resistance, and rail displacement by multiple devices, and the problem that the indication gap value is affected by the displacement change of the inspection column itself.

[0008] In order to solve the above technical problems, the utility model provides a turnout health monitoring system, which adopts the following technical solutions: including a trackside collection extension, a station machine, a server and a terminal, wherein the trackside collection extension also includes a gap indicating sensor, a conversion resistance sensor, a rail displacement sensor, and an external locking oil injection device;

[0009] The outer side of the trackside collection sub-machine is connected to a plurality of groups of connection cables and connection oil pipes. Switch machines are also respectively arranged on both sides of the trackside collection sub-machine. The switch machines include switch machine indicating rods and switch machine inspection columns.

[0010] Optionally, the indication gap sensor is composed of a camera bracket, an LED module, a laser ranging module and an image sensor module. The light source of the LED module is parallel to the direction of the switch indicator pole, thereby avoiding overexposure of the indication gap sensor image due to reflection of the switch indicator pole, and at the same time improving the distinction between the gap gap and the switch indicator pole image, thereby improving the success rate of identifying the edge of the switch indicator pole.

[0011] Optionally, the indication gap sensor measures the distance value A1 of the switch inspection column relative to the indication gap sensor by setting a laser ranging module, and the trackside collection extension collects the indication gap sensor data, obtains the indication gap edge position of the switch indicating rod through the image sensor module, obtains the position of the switch inspection column through the laser ranging module, and calculates the indication gap value A2.

[0012] Optionally, the rail displacement sensor can select a rail lateral displacement sensor a or a rail creeping sensor according to usage. The rail displacement sensor is deployed on the action connecting rod, and the conversion resistance of the turnout is monitored by measuring the deformation of the action connecting rod at the traction point to obtain data and send it to the trackside collection extension. The rail displacement sensor is responsible for monitoring the lateral displacement and creeping status of the rail. Each group of turnouts is deployed with two sets of rail lateral displacement sensors and rail creeping sensors to obtain data and send it to the trackside collection extension.

[0013] Optionally, the external locking oiling device is installed above the external locking frame of the turnout. The trackside collection extension can spray lubricating oil onto the external locking friction pair through the external locking oiling device via a connected oil pipe, thereby reducing the unlocking and locking friction force. The station machine collects data from the trackside collection extensions of all turnsouts in the entire station and displays the turnout operating conditions in real time.

[0014] Optionally, the server collects data from all stations on the entire line and can provide a turnout health assessment report, and push alarm information on turnout health anomalies to the terminal. Maintenance personnel can receive health anomaly alarm data of all turnouts under their jurisdiction through the terminal and can query the real-time working conditions of the turnouts.

[0015] Optionally, when the trackside collection extension senses that the switch switching resistance is abnormal, it directly drives the external locking oiling device to inject oil, thereby achieving the purpose of rapid closed-loop control.

[0016] Optionally, the notch sensor, conversion resistance sensor, and rail displacement sensor are all provided with CAN cascade interfaces, so that the sensors in the turnout health monitoring system can be deployed in cascade, reducing the number of on-site connection cables to be laid.

[0017] In summary, the present invention has at least one of the following beneficial effects:

[0018] 1. The turnout health monitoring system designed in this scheme consists of a trackside collection extension, a station machine, a server and a terminal.

[0030] In summary, the components and technologies described in the solution are mainly used to realize the data collection, monitoring and analysis functions of the turnout health monitoring system, thereby improving the safety and reliability of turnout equipment and reducing maintenance costs.

[0033] The rail displacement sensor 103 can select a rail lateral displacement sensor 103a or a rail creeping sensor 103b according to the usage. The rail displacement sensor 103 is deployed on the action connecting rod, and the conversion resistance of the turnout is monitored by measuring the deformation of the action connecting rod at the traction point to obtain data and send it to the trackside collection extension 100. The rail displacement sensor 103 is responsible for monitoring the state of the lateral displacement and creeping of the rail. Each group of turnouts is deployed with two sets of rail lateral displacement sensors 103a and rail creeping sensors 103b to obtain data and send it to the trackside collection extension 100.

[0034] The external locking oiling device 104 is installed above the external locking frame of the turnout. The trackside collection extension 100 can spray the lubricating oil onto the external locking friction pair through the external locking oiling device 104 by connecting the oil pipe 106, which can reduce the unlocking and locking friction. The station machine 200 collects data from the trackside collection extensions 100 of all the turnouts in the entire station and displays the turnout working conditions in real time.

[0035] In summary, the above technologies and components work together to build a comprehensive turnout health monitoring system that can comprehensively monitor and record various key parameters of the turnout, provide accurate data to ensure the normal operation of the turnout, reduce maintenance costs, and provide early warning of potential problems, which helps to improve the safety and reliability of the railway transportation system.

[0037] Server 300 collects data from all stations on the entire line and can provide a turnout health assessment report, and push alarm information of turnout health anomalies to terminal 400. Maintenance personnel can receive health anomaly alarm data of all turnouts under their jurisdiction through terminal 400, and can query the real-time working conditions of the turnouts.

[0038] When the trackside data collection extension 100 senses that the switch switching resistance is abnormal, it directly drives the external locking oil injection device 104 to inject oil, thereby achieving the purpose of rapid closed-loop control.

[0039] The notch sensor 101 , the conversion resistance sensor 102 , and the rail displacement sensor 103 are all provided with CAN cascade interfaces, so that the sensors in the turnout health monitoring system can be deployed in cascade, reducing the number of on-site connection cables 105 to be laid.

[0040] In summary, the role of the above features in the solution is mainly to optimize the health monitoring system of the turnout, making it more intelligent and efficient, which helps to improve the availability of turnout equipment, reduce the risk of failure, and reduce the complexity and cost of system maintenance.
