Background and challenge
The railway traffic safety system is a complex giant system composed of “one man, one machine and one linkâ€, and it is the marginal area where cross-border and integration of transportation safety engineering, safety and reliability engineering, and safety ergonomics. Driving safety is the eternal theme of the railway, and the performance of the locomotive flight attendants during driving is the key to safety. How to build a video surveillance system for trains that is compatible with the development of railways to serve as a deterrent, early warning, forensics, command and rescue, and management functions for passengers in cars, prevent, reduce public security and criminal cases, and become an urgent need for railway train video surveillance. solved problem.
The system communicates with the LKJ train operation monitoring and recording device in real time, and combines the monitoring information to record the locomotive operation and the driver's standardized operation. Can provide monitoring screen and alarm information instead of driver inspection; download files through mobile hard disk or wireless transmission; with perfect ground analysis and processing functions, perfect image, voice, monitoring information three-in-one analysis interface, can combine locomotive LKJ Synchronization of device information and ground data, multi-screen reconstruction of locomotive operating status and driver operating conditions will play a significant role in accident prevention, accident analysis, and supervision crew operations. The device can also support fire smoke alarms.
solution
Locomotive video surveillance system architecture consists of three parts: front-end video capture system, transmission system and central management system.
The vehicle-mounted front-end video acquisition system consists of a vehicle-mounted monitoring subsystem. The on-board monitoring system collects and stores video and audio and GPS information through the on-board NVR main unit, vehicle IPC, and emergency alarm buttons, and transmits it to the central management system through the NVR's built-in 3G/4G wireless module.
The transmission system consists of 3G/4G wireless mobile communication transmission links and fixed-line private transmission links. After receiving the data information from the front-end train, the communication base station sends the data to the fixed network dedicated to the monitoring center through the gateway.
Railway locomotive video monitoring system solution
The center management system is the core of this system and is the place where daily monitoring and emergency command are performed. The central management system realizes the control of the vehicle-mounted front-end system through the wireless network, realizes functions such as video and audio monitoring, GPS positioning, locomotive line management, voice intercom, etc., and can upload data storage, summarization, generate back-end management reports, and realize locomotive maintenance management and lines. Operations management and other functions. In order to meet the needs of customers, it is required to back up data storage at the monitoring center and adopt IPSAN storage at the monitoring center. In order to facilitate the customer to view the train's internal monitoring screens, the video synthesis platform is used to decode the monitoring image on the wall, and the video wall consists of Haikang's splicing screen composition. The software platform supports the access of the network keyboard, provides user-friendly operation functions, and facilitates the operation and control of the user on the wall display and image layout.
Highlights of the project
1) Combining video surveillance with GPS positioning
The system fully considers the needs of mobile surveillance, and combines leading audio and video codec technology, GPS satellite positioning, wireless network transmission and other technologies to form a set of advanced and rapidly deployable train video surveillance systems.
Through this system, the system can not only monitor the geographical position of the locomotive in real time, but also monitor the command center through wireless video transmission technology to watch the real scene on-site through the on-board wireless video, so as to follow the tune and see it. effect.
When a moving locomotive generates an alarm, the monitoring center can make scientific and rapid decisions based on various data in the shortest possible time through the image of the backhaul, and direct and schedule various resources in a timely manner.
2) Compact structure and high integration
The traditional train video surveillance system generally adopts the way of vehicle-mounted monitoring and GPS separation. As a result, the equipment is complicated to connect and there are many connections, resulting in a problem of low reliability in a large-vibration environment. Need to use two communication cards, there is obviously the problem of high costs.
Therefore, the vehicle host that uses the built-in GPS module is selected in this system, which solves this old problem well.
3) Military-grade vehicle quality
The selected vehicle-mounted hard disk recorder has excellent military quality. Its hard disk damping and reinforcement technology is based on the military technology of the 52nd Institute of China Electronics Technology Group. Under the guidance of the military structural design experts, this product structure designer has independently researched and developed the hard disk reinforcement module by referring to the military standard (GJB367A-2001 General Information Specification for Military Communications Equipment of the National Army Standard). The product passed a large number of environmental tests and currently meets and exceeds the requirements of the relevant military vehicle equipment.
4) Strong environmental adaptability
In this design, the selected products not only meet the harsh climate environment, but also they can resist the harsh electromagnetic environment; the selected camera is in line with the outdoor use requirements, and its protection class is IP66; Hikvision TV series hard disk video recorder is aimed at the locomotive operating environment. It is poor and has high requirements for heat dissipation, dust prevention and waterproofing. It is specially treated to meet the requirements for long-term operation under special conditions in the vehicle. Its protection class is IP54.
Each hardware interface of the car DVR is equipped with a screw lock, and the connection with external devices is solid and reliable.
In order to ensure that there is no electromagnetic interference on other equipment in the vehicle and to shield the external interference on the vehicle-mounted equipment, Hikvision Car DVR performs special treatment on the fuselage and has passed the EMC test to meet the requirements of GB-13837-2003 standard. . Car DVR, power supply design is based on the ISO7637-2:2004 "Road Locomotive - Electrical Disturbance Caused by Conduction and Coupling" standard design and can filter power supply glitches up to DC 153V to ensure stable operation of the equipment. The power supply has been specially designed to provide the functions of open circuit, short circuit, over-current and overload protection, which plays an important role in ensuring the normal operation of the equipment.
