[0018] The present invention is further described in detail below through the accompanying drawings and specific embodiments.

[0019] like Figure 1 As shown, an embodiment of the present invention provides a method for monitoring the safety of a railway port freight yard, comprising the following steps: S1. Obtain the real-time location information of the operating personnel and operating equipment on the existing operating railways; S2. Building a railway online operation safety management and control platform in the form of an online map; using the railway online operation safety management and control platform to publish online operation plans and define the scope of the operation space; S3. Monitor the working status of operators and equipment based on the real-time location information obtained, verify the work plan based on the published online work plan, record the compliant work process based on the verification results, and issue early warning for the illegal work process.

[0020] In S1, the workshop of the railway engineering department is taken as the basic unit, and the positioning terminals are equipped for the operating personnel and equipment on the existing operating railway lines, and the corresponding parameter settings are completed. The personnel are equipped with electronic bracelets, work cards, safety helmets, smart phones that meet the positioning accuracy and other light wearable device terminals with GNSS real-time positioning function, and GNSS receivers are configured for medium and large equipment. The above terminals should meet the parameter requirements of positioning sampling frequency not less than 1min / time and positioning accuracy not less than 1m, so as to realize the real-time position sampling of online operating personnel and equipment. Before the operation, the on-site person in charge will bind the formulated operation plan with the positioning terminals of the operating personnel and operating equipment on the mobile terminal of the front-end information platform for railway line operation safety management and control. Specifically, it can be achieved in two ways: ①By scanning the QR code on the terminals such as the wristbands, work cards, safety helmets and GNSS receivers for positioning personnel and equipment, the binding with the existing operation plan is realized; ②After selecting the operation plan through the mobile terminal, the specified terminal is selected from the existing positioning terminals according to the terminal sequence to complete the binding of the operation plan and the use of the positioning terminal.

[0021] Optionally, in S2, the building of a railway line operation safety management and control platform includes the following steps: S201. Access public map services in the form of online maps, and build a B / S mode thematic geographic information system for real-time visual display. Specifically, use mainstream WEBGIS frameworks such as OpenLayers, Leaflet, and Cesium to access public map services (satellite images, electronic maps, annotations) in the form of online maps, and build a B / S mode thematic geographic information system for real-time visual display of the positioning trajectory of equipment and tools of railway line operators, which will serve as a display platform for the positioning terminal trajectory, real-time location information, and operating scope information of equipment and tools of railway line operators.

[0022] S202. Based on the railway line design data, line mileage marks are produced for mileage positioning in map mode, and element information: railway line position, bridge piers and mileage; are superimposed on the B / S mode thematic geographic information system for real-time visual display.

[0023] S203. Formulate and publish online operation plans and define the scope of operation space according to the requirements of the railway section bureau, station section and workshop levels.

[0024] Collect design data files (PF data and bridge pier mileage table) of the operating lines under the jurisdiction of the railway bureau's engineering department, make line mileage marks, enter the results of kilometer marks and hundred-meter marks into the database, realize the two-way association between mileage and spatial position, make thematic maps of railway line positions, mileage marks, buffer zones, bridge pier marks and other thematic element information and publish them in the form of data services, superimpose them on thematic geographic information systems for intuitive display, and switch to the map position of any mileage in the map mileage navigation.

[0025] According to the three levels of railway bureau, station section and workshop, online operation plan, positioning terminal, workshop, operating personnel, early warning information and other contents are realized, and the business work content of online operation safety management and control is developed informatized, and the positioning terminal information and line, personnel, workshop and other information in S1 are entered into the system.

[0026] Optionally, in S3, monitoring the working status of the operator and the working machine according to the acquired real-time location information includes the following steps: S301. Decode the real-time location information of the operating personnel and the operating equipment; decode the communication information sent back by the positioning terminal on the server side according to the agreed data protocol through the TCP or UDP communication protocol and convert it into plain text information. The data protocol currently used is mostly "Technical Specifications for Beidou-Compatible On-board Terminal Communication Protocol of Road Transport Vehicle Satellite Positioning System" (Ministry of Transport 808 Protocol), and maintain the communication connection in accordance with the protocol requirements.

[0027] S302: extract data from the decoded real-time location information, wherein the extracted data includes device coding information and the longitude and latitude coordinates of the device's real-time location, and store the extracted data in a database.

[0028] S303: Based on the published online operation plan and the delineation of the operation space, the extracted data is monitored in real time.

[0029] S304: Visually display the real-time positions of the operators and the operating equipment based on the extracted data.

[0030] Optionally, the monitoring of the working status of the operating personnel and the operating equipment also includes updating the connection status, battery power and signal status monitoring results of the positioning devices of the online operating personnel and the operating equipment on the railway line operation safety management and control platform.

[0031] In existing conventional and high-speed railway operations, protection personnel and operating personnel jointly wear selected terminals, and large-scale operating machinery and equipment carried by personnel remain powered on to realize real-time location collection and analysis in the background. Real-time refresh of multiple terminals’ real-time positioning trajectories and the most recent sampling positions, visual display of the operating activity trajectories and real-time sampling positions of the positioning terminals in the front-end map, and symbolic representation of the real-time position of the positioning terminals and their spatial positional relationship with the railway line and operating scope. Differentiated symbols and animation rendering are used to distinguish normal and out-of-bounds trajectories and real-time positioning points, emphasize and warn out-of-bounds equipment and trajectories, and visualize the rendering effects and details after zooming in on the equipment positioning trajectories and real-time positions.

[0032] Optionally, when the warning process is performed on the illegal operation process, the illegal operation situation and the warning process include at least the following three aspects: 1) For illegal cross-border operations by personnel during operation, the monitoring and positioning terminal will calculate and record the over-range and over-mileage operations in real time, and calculate the cross-border time, maximum cross-border distance and number of cross-border operations; 2) For overtime operations, monitor the online and offline time periods of the positioning terminal in advance and overtime operations through time series and spatial analysis; 3) Monitor intrusion by external workers and equipment, and monitor intrusion by other workers and equipment in real time.

[0033] As shown in formula (2), the real-time sampling position and sampling time of a positioning terminal at any time, combined with the spatial and temporal analysis between the sampling terminal's associated operating range and the railway mileage line position, are used to solve the current positioning terminal's real-time crossing, timeout, crossing distance, and railway mileage information. Specifically, by obtaining the continuous sampling point coordinates and the corresponding timestamp information, with the help of spatial topology analysis, the positional relationship between each sampling point and the operating range is calculated to determine whether the device has crossed the boundary. According to the timestamp information of the sampling point and the start time of the operation specified by S303, the time of the overtime operation is determined and calculated. With the help of the continuous sampling point information of a single device, the crossing distance from the sampling to the operating range is calculated, and the accurate mileage information of each sampling point is obtained by conversion through the relationship between railway mileage and spatial coordinates.

[0034] When issuing online work tasks, the work management personnel of the engineering department shall report the work information through the railway online work safety management and control front-end information platform, including the work name, line, work start time and starting and ending mileage, and the number of workers and equipment.

[0035] According to the line where the operation is located and the starting mileage, the accurate line section is confirmed, and the line data and line form (bridge, tunnel, roadbed) are automatically calculated through the buffer zone to obtain the precise spatial range of the operation range. The spatial reference basis for the subsequent terminal positioning electronic fence calculation is shown in formula (1). The operation range is automatically calculated through the buffer zone calculation based on the reported operation information and the line mileage information calculated on the map, where and represent the starting and ending mileages, represents the line position, and D represents the lateral operation range (taking the line roadbed and bridge width). The precise line position direction and interval range are determined by and, and the lateral width is determined by the precise operation range. The calculated operation range is obtained by buffer zone analysis. The calculated operation range can be manually adjusted through the front-end information platform for operation safety management and control on the railway line.

[0036] The front-end information platform for railway line operation safety management and control displays the operation scope on a map. For line switches, stations and other areas, the actual scope obtained by automatic calculation can be manually adjusted through vector editing.

[0037] After the operation is completed, the number of personnel and operating equipment on site is counted and compared with the number reported in the operation plan, the working status of the positioning terminal is checked, and photos of the on-site workers and equipment are taken and uploaded to the front-end information platform for railway line operation safety management and control, and the electronic timestamp is saved.

[0038] In the indoor operation control room, the operation screen is used to monitor the real-time status of multiple lines and multiple operations and the statistics of illegal operation behaviors in real time. The operation information of each line can be queried in real time on the visual monitoring screen, and can be quickly switched to the specified operation. Optionally, S4 is also included. According to the early warning information, the information of the personnel or operating equipment who violates the regulations is sent to the on-site operation person in charge and the control department to verify the illegal operation. After the verification, the alarm is eliminated in the terminal or platform; after the online operation is completed, the staff and equipment are counted offline, and the operation records are filled in.

[0039] After the operation is completed and offline, the completion status of the operation is reported, and the personnel and machinery and equipment are counted again, and photos are uploaded to verify that the content and quantity counted before going online are consistent, and the inventory and on-site confirmation records are retained. Operation statistics, warning records, and disposal records are retained to achieve the backtracking of the positioning trajectory of the operating personnel and equipment and the statistical analysis of warning records, so as to achieve a closed loop of the operation completion process.
