In the marshalling station of the railway system, because it undertakes the dismantling and marshalling of a large number of freight trains, train inspection and cargo inspection, it can be said to be the core part of the entire railway system.
Since the decomposing of various types of freight trains, the organization and delivery of local traffic, the technical overhaul of the locomotives and vehicles in the freight trains, and the freight inspection and finishing work need to be completed within a specific time, how to improve the marshalling station The work efficiency is one of the core tasks of marshalling station management and operation.
The current low efficiency of marshalling stations is mainly reflected in:
First, the railway operating system, as an operation management software system, usually carries information about all relevant work of the railway's corresponding system or area. For marshalling stations, the business process mainly carries the data information for dispatching trains, but under normal circumstances, the data information in the software system cannot interact with the voice information. For example, if the staff of the handheld walkie-talkie wants to understand the operating system, they need to run to the computer system and perform corresponding operations and inquiries.
Second, the communication equipment that currently occupies a large share of marshalling stations is still traditional office phones, walkie-talkies, and shortwave radios. Due to different standards, these devices cannot communicate directly, resulting in low communication efficiency, which in turn affects the working efficiency of the entire railway marshalling station.
Therefore, the marshalling station management of the railway system urgently needs a powerful "converged" solution to help it integrate a variety of information resources and equipment, so that the railway operation software system and the communication system, wired and Wireless systems can truly be integrated into one, helping railway marshalling stations to improve their operation and management capabilities, reduce management and operation costs, and solve or improve various increasingly complex situations.
With the help of the "Multimedia Converged Communication System" provided by GES Technology, the dispatching system of the railway unit can be connected to the railway software operating system. The mobile staff of the marshalling station can send and receive information of the railway operating system through the intelligent terminal, and The information carries out corresponding dispatching work or accepts and issues dispatching instructions, thereby greatly improving the working efficiency of the railway marshalling station system.
Railway marshalling station communication status and demand
The core part of the railway marshalling station is the dispatch center, which is responsible for directing and dispatching the arrival of freight trains, inputting information into the database, disassembling according to the plan, regrouping, and starting. And then sent to the relevant departments of the railway bureau through the railway backbone network in the form of electronic reports, and at the same time transmitted to the next railway marshalling station to ensure the accuracy and speed of the information.
At the same time, during the period when the freight train stays at the iron marshalling station, the locomotive section needs to supply the train power, as well as the maintenance and repair of the locomotive. The depot and its subordinate units (station repair station, train inspection station) shall carry out daily maintenance and regular maintenance on vehicles. The multi-unit, multi-department and multi-work collaboration work caused by this also puts forward higher requirements for scheduling work.
The business features in the dispatch communication of marshalling station are as follows:
Operation flow of marshalling station train scheduling as the core data scheduling business
The operation process of the voice dispatching service mainly based on the first-line operators of marshalling stations
There are many depots and subordinate units (station repair stations, train inspection offices) located in marshalling stations, which are responsible for different businesses
Multi-unit, multi-department, multi-working types work together
Many marshalling station staff need mobile office
Workplaces are scattered and resources are constantly moving
Strong timeliness and strict time requirements
As a voice support system for production scheduling of marshalling stations, voice scheduling must be able to meet the characteristics of station business
In this solution, the voice system can be linked with the marshalling station business system to meet the requirements of the marshalling station business
Voice communication groups are reorganized according to business dynamics
Scheduling according to business logic identification, not phone number scheduling
Taking into account the business application characteristics of the marshalling station, the relevant leaders of the marshalling station in this project require that the newly deployed multimedia converged communication system can effectively and reasonably schedule various human and material resources in accordance with the marshalling station ’s marshalling plan. In accordance with the requirements of the work plan, timely and accurate handling of the disassembly and marshalling of freight trains, and in the event of an emergency, can dispatch the staff of various departments to work together to ensure that the emergency is resolved in the shortest time and guarantee The marshalling station works orderly and efficiently.
Open and interoperable multimedia fusion communication system
If the railway marshalling station wants to effectively and rationally dispatch various human and material resources according to the overall plan, and handle the disassembly and marshalling of the train accurately and in a timely manner within the specified time, it is necessary to be able to dispatch each emergency when an emergency occurs Department staff work together to ensure the resolution of emergencies in the shortest possible time. An integrated platform system is required to integrate the software operation system, automation system, and multimedia communication platform of the railway system.
The multi-media dispatching system customized by GSR Technology for railway marshalling stations is mainly distributed in indoor fixed office areas and outdoor operation areas.
The indoor fixed office area, including voice scheduling platform, data scheduling platform and administrative office subsystem, is used as an area for data processing, telephone communication, voice scheduling and corresponding management.
The outdoor work area, including the wireless trunking subsystem and the original intercom subsystem, both of which can realize inter-standard intercom through GTS Gateway of Jiesiri Technology, and both can be interconnected with the system in the indoor fixed office area at any time. It includes functions such as voice communication, video and image acquisition, data sharing, and operating system information sending and receiving.
1. Data scheduling platform: This platform includes railway OA system, operating system, database system and other working systems. The information resources provided by these systems can be connected and interacted with the intelligent terminal of the scheduling system to realize the video surveillance image. Call, data query and job information sending and receiving.
2. Voice Dispatching Platform: The platform selects the MDS multimedia dispatching system of Jiesirui Technology as the core voice control platform of the station, which is mainly responsible for the management of the entire dispatching system, terminal registration, voice dispatching and instruction message forwarding. The system can achieve interoperability with the traditional PSTN network through the GA90 gateway.
3. Administrative office subsystem: It is mainly used for voice communication between administrative personnel in fixed offices in the station. The system can communicate with other systems and send and receive data information.
4. Wireless cluster subsystem: It is convenient for the front-line operators of the station to communicate data and voice in the mobile working state through the wireless network. Through the use of wireless broadband smart terminals, video and image collection, and voice calls can be achieved. The system can also be extended to locate people and vehicles, and through the video monitoring system, see the operation dynamics of each person and vehicle;
5. Original intercom subsystem: The original digital intercom of the railway marshalling station can still be used normally, and through the GTS cluster docking gateway, it can realize seamless voice communication with the newly deployed wireless broadband intelligent terminal and office subsystem.
Advantages of multimedia converged communication platform
1. The efficiency improvement is very significant. In the past, dispatching centers or depots used printing plans and tasks as paper work schedules to dispatch to field staff. Once an emergency occurs, it is difficult for dispatching centers or depots to coordinate arrangements quickly and in time, resulting in duplication Sex work.
Now that the front-line workers are equipped with handheld McWill smart terminals, workers in the mobile state can directly access the OA and other business systems from the terminal, call data, and enter the operation process, instead of holding paper work as before. The plan is delineated and finally returned to the office for unified entry, which is convenient to operate and saves time.
2. Respond quickly to emergencies. There is no interconnection between various traditional communication devices, and the best time for handling is often missed when an emergency occurs. With the application of the new system, the staff can take pictures through the distributed intelligent terminal with camera function or camera function, send it back to the command center and make a voice call, avoiding the multiple dispatch of personnel due to insufficient understanding of the scene But it has never been able to solve the embarrassing situation of the problem.
3. Centralized management. In the dispatch center of the dispatch center, the current status of all terminals and all the operating conditions of the station can be visually displayed. Workers in the dispatch center can centrally monitor and control all operations such as station arrival, solution, assembly, editing, and dispatching, so as to obtain the effects of single command, unified handling, pipeline execution, and efficient operation.
In addition, according to the specific organization and scope of responsibility of the railway marshalling station, a variety of scheduling levels can be grouped and set on the scheduling platform, with different authorities assigned to flexibly control scheduling operations.
4. Diversified scheduling methods. Voice scheduling, SMS scheduling, and instruction scheduling are available. In addition, the platform can record the calls generated by the entire system in real time, and can inquire according to various conditions such as time and number. Because it is very important to keep text and voice data, it can not only be used as an action guide for the work site, but also provide sufficient evidence for the need to clarify responsibilities in the event of a situation.
5. Make full use of resources. According to the actual situation, different communication terminals can be distributed for the working characters of different types of work. After the seamless communication between the various communication terminals is realized, the original communication equipment is fully utilized, the original investment is protected, and no resources are caused. waste.
6. Strong scalability. The rich API interface provided by the dispatching host can be connected with production and operation software and ERP software, and integrate various wired and wireless networks of the station and the business system of the station. Such as docking with the station video conference system, you can achieve video conference during the call; docking with the video surveillance system, you can control the video surveillance camera on the dispatch desk to understand the first-line situation in real time.
7. Business process reengineering. When the integrated communication of railway marshalling stations develops to a certain extent, it will cause the reengineering of production processes and the reorganization of business. Because the new communication system of the railway marshalling station realizes the sharing of information and data, it is bound to optimize the connection between the previous processes and the overall process. It can reduce the communication and contact time of manual planning and control, communication and coordination of operators and live report, and improve the overall operation efficiency of the railway marshalling station.
With the continuous advancement of railway industry informatization and the rapid development of high-speed rail, only the platform system that can integrate various information systems and equipment (software, automation equipment, communication equipment) can truly meet the needs of the railway industry for efficient and modern operations. The “barrel effect†caused by the inability to connect various information systems or the inefficiency of various systems will not appear, which will make the investment of the railway sector in vain and the need for job promotion cannot be realized.
At present, this multimedia converged communication system has been applied to Fengtai West Station in Beijing and Shijiazhuang South Station in Hebei Province, and has been well received by the leaders of relevant railway departments. It is believed that this system has solved many software and hardware systems of railway marshalling stations However, the problem of being unable to communicate with each other has doubled the efficiency of the railway marshalling station.
A multimedia converged communication platform with a high degree of openness, integration, and the application of wireless broadband networks that can implement modern multimedia scheduling of video, voice, and data will also be valued by the relevant railway departments and more widely used.
