Railway patrol system - Railway Intelligent Patrol communication system

For a long time , Railway transportation plays an important role in China's transportation industry . And the railway accidents happen frequently , It reflects the daily maintenance of train equipment in China 、 Execution of shunting operation 、 There are still serious drawbacks in the operation of patrol inspectors .

The importance of railway patrol inspection system

2008 year 4 month 28 Japan , Beijing to Qingdao T195 The No. passenger train is off-line from Zhoucun to Wangcun of Jiaotong Jinan Railway in Shandong , The first 9 Festival to 17 A car derailed at a railway curve , Rush to the outside of uplink base . here , From Yantai to Xuzhou in normal operation 5034 The passenger train failed to brake 、 Finally, every hour 70 The speed of KM collides with the derailed vehicle , The accident caused 72 People have been killed ,416 People were injured . The accident was finally identified as a human responsibility accident .

There is data showing , Although the railway inspector 、 The maintenance personnel conduct regular inspection , However, due to the dereliction of duty of the post staff 、 Mind paralysis 、 The proportion of accidents caused by the existence of fluke mentality is about 80% above .

so , Ensure that the daily inspection of railway transportation lines and equipment is in place 、 Timely maintenance , Strengthen on-site inspection , Create a set of basic voice communication that can meet the needs of all links of railway patrol inspection , It also realizes the new communication mode of intelligent management and three-dimensional command and dispatching , It is undoubtedly to eliminate all kinds of potential safety hazards 、 Powerful measures to ensure safe train operation and people's lives and property .

Industry demand analysis

The span along the railway is large 、 More points 、 Scattered places 、 Complex site environment . The traditional inspection mode only relies on the naked eye or ordinary instruments , Not only the workload 、 Slow information transmission 、 Low efficiency 、 The operation and maintenance cost is high , And in case of danger, it cannot respond in time . Based on the above problems , The following requirements are formed for the railway intelligent inspection system ：

1、 The system construction is convenient , The cost is low , Simple maintenance .

2、 Standardized work , Ensure that patrol inspectors carry out patrol inspection according to the designed route .

3、 The dispatcher can view the dynamic information and moving track of patrol inspectors at each position in real time .

4、 The patrol inspectors clock in the daily patrol 、 Data collection and real-time problem reporting .

5、 Operation status of train equipment 、 Integration and analysis of historical data such as parameters , Improve emergency early warning and response capability .

6、 The management center and relevant departments can view and query the patrol inspection status online at any time .

Beifeng Railway Intelligent Patrol communication system (8100SDC) Introduce

Beifeng Railway Intelligent Inspection communication system is based on advanced DMR Digital wireless communication technology , Comprehensive use GIS Satellite positioning technology 、 intelligence IP Internet technology 、 Fully integrated communication technology and rich voice scheduling functions , Provide daily patrol clock for patrol inspectors 、 Dynamic position tracking 、 Real time voice information interaction and emergency support .

Besides , The system is controlled by the client dispatching center 、 The system consists of data exchange control server, digital relay station and handheld terminal , Patrol inspectors can send various status information through handheld terminals ( Include ： Patrol the route 、 Real time work status check 、 Fault location 、 Emergency alarm, etc ) Integrated application and wireless communication are skillfully integrated into one , Realize patrol inspection personnel 、 Network interconnection and information sharing between dispatcher and client dispatching center , It ensures the stability of railway patrol inspection 、 Reliability and controllability , Effectively reduce the occurrence of safety accidents , Improve the work efficiency and management and dispatching ability of railway management departments .

Application advantages

1、 whole IP Chemical technology , Low maintenance cost

Set up relay equipment according to the traffic volume required by different railway stations , Integrating intelligence IP Internet technology , Cloud deployment , Construction is simpler 、 Lower maintenance costs . The station communication only starts the relay of the station , Cross station single call only starts the relay of two stations , The inter station group call only starts the site relay with the terminal to which the group call belongs , Ensure multi site 、 Multisectoral 、 Interconnection among multiple personnel .

2、 Patrol management function

Define the inspection rules according to the specific management requirements of railway inspection . The user can define the patrol times and patrol time of each line every day through the use of patrol rules , Or define the daily patrol inspection times of each line as 、 Time . The patrol inspectors pass the active RIFD Or passive RIFD Identify points to record the actual records of each guard tour during patrol inspection . The platform administrator can manage the patrol shifts of operators 、 Patrol plan monitoring 、 Patrol route management and unified summary 、 management 、 Make it clear .

3、 Intelligent platform , Unified scheduling

The system can realize cross system support through the integration gateway 、 Cross network unified command and dispatching communication . The railway dispatching center can command and dispatch the terminal of patrol inspectors , Provide single call 、 Group call 、 Voice calls such as general calls , It can also be found in GIS A flat map 、 Visual real-time dynamic scheduling under satellite map 、 Command issuing and voice / Information scheduling .

4、 Data management , Auxiliary patrol inspection tasks

be based on GIS Data information platform and satellite positioning function , Form patrol route planning 、 Patrol inspection area fence 、 Punch in the exchange shift 、 Clock in at the patrol point 、 Satellite positioning 、 Powerful databases such as digital recording . When a dispatcher or administrator creates a patrol task , And send it to the designated patrol inspection personnel terminal , The administrator can view the working conditions of personnel in the dispatching console in real time , It is convenient for patrol inspection management and dispatching .

meanwhile , It supports personnel patrol inspection 、 sound recording 、 Shift handover 、 Locate the track 、 Attendance 、 Equipment on / off 、 Send text messages and positions 、 department 、 End users and other management colleagues can carry out classified query and multidimensional statistical analysis on relevant data and generate reports .

5、 Emergency help , Ensure personnel safety

The handheld terminal has the function of emergency help , During patrol inspection , In case of emergency, the personnel will automatically call for help . The dispatching center can quickly lock the real-time position of personnel , Immediately and accurately notify nearby personnel to provide assistance , Reduce accident losses and casualties .

5、 ... and 、 reflection

The occurrence of railway safety accidents , Not by chance . Beifeng Railway Intelligent Patrol communication system (8100SDC) Realize the real-time exchange of daily inspection information , It is convenient for the management department to effectively supervise the patrol 、 Implementation of patrol inspection , Effectively eliminate hidden dangers , Reduce maintenance costs . Compared with the traditional patrol mode , Communication transmission and emergency response speed 100% promote , Improve command efficiency , Easy for rapid deployment , Really nip the potential safety hazard in the bud .
