The locomotive video monitoring and recording device is a cost-effective, well-expandable device for video monitoring and recording of drivers. It uses a high-speed processor and embedded operating system, and combines the most advanced H.264 video compression/decompression technology in the IT field, network communication technology and GPS positioning technology. This device is divided into two models: SDRV-1-8CH and SDRV-1-4CH, which respectively support 8 and 4 channels of video recording at the same time. The system can realize video recording in CIF, HD1 and D1 formats, record driving information, and expand 2G/3G network wireless data upload. With ground analysis software, it can playback and display the recorded video data and TAX box data, so that ground analysts don’t need it. With the addition of other data sources, it is possible to visually and intuitively analyze the operating conditions of the driver and the operating conditions of the locomotive. By adding 2G/3G communication modules, central monitoring, remote management and playback analysis based on the central database of various monitoring events can be realized. The equipment has the characteristics of simple appearance, super anti-vibration, flexible and convenient installation, powerful functions, stable operation and high reliability.
success case:
Construction of the first, second and third phases of the video monitoring and recording device for drivers on duty of Guangzhou Railway; 15 DF7 diesel locomotives installed in the Huaihua Locomotive Depot of the Guangzhou Railway Group with a diesel engine monitoring device project
1. Application background
Since the implementation of six large-scale speed increases and the commissioning of multiple passenger dedicated lines with speeds of 250 kilometers per hour and 350 kilometers per hour, the organization of trains has undergone tremendous changes, achieving major changes such as growth, heavy load, and single-driver duty. With the continuous deepening of the leap-forward development of the railway, the requirements for flight attendants are getting higher and higher, and new requirements are put forward on how the locomotive system can improve driving safety. The locomotive wireless video monitoring device applies audio and image digital processing technology, 3G, WIFI wireless transmission technology, real-time monitoring of the locomotive cab, equipment room, and front and rear lines, etc., which can not only supervise the crew to perform standardized operations seriously, but also prevent the locomotive The occurrence of accidents such as fire and damage to large parts.
The system shares the monitoring TAX comprehensive information in real time and saves the important data of LKJ in the image frame information in real time; all realizes the true reproduction of the accident; it provides a strong scientific basis for analyzing the responsibility and judging the accident.
2. System features:
1. Embedded professional vehicle design, high stability, no crash, no data loss, durable and convenient maintenance, excellent anti-locomotive vibration and anti-electromagnetic interference performance. It is an industrial-grade special product and has officially passed the US Army 810F Electronic Product Environmental Army Mark;
2. The video recording part of the host adopts a professional embedded four-channel (eight-channel) digital surveillance video recorder, which has the characteristics of fast start-up, high reliability, high compression ratio, high definition, high temperature resistance, shock resistance, etc.;
3. You can use plug-in hard disk or USB2.0 download method to access image data;
4. The external interface of the host adopts the professional aviation connector of the locomotive, which is stable and easy to use;
5. In view of the special structure and video recording requirements of the locomotive, the cameras adopt special fixing and shock absorption methods. The video capture control of the video recorder is also set according to the working conditions of the locomotive;
6. The host can collect 8 channels of video signals and display them simultaneously on the LCD monitors in the cabs at both ends, and can quickly switch the display; as the core equipment, the on-board host is responsible for compressing and encoding the video images of each monitoring point collected by the camera Then it is transmitted to the monitoring center through the 3G network to realize the remote viewing of the video. After the locomotive stops and enters the station, the video data of the video recorder is automatically uploaded through the WIFI network for subsequent analysis.
7. The dedicated LCD screen integrates keyboard control, image display, audio input and other functions.
Three, the main function
1. Video camera function: Fully record the road conditions in front of the locomotive, important areas of the locomotive, the standard operation of the driver and the working status of the non-control end.
2. Recording function: Synchronous recording of voice messages in the driver’s cab and flight attendants through a dedicated miniature pickup.
3. Item image capture function: by setting driving, parking, monitoring actions, man-made emergency, sideline operation, entering shunting, shunting, exiting shunting, red and yellow signal, excessive phase point, special area, internal combustion shutdown, 14 types of item points such as switch video, relay transfer, etc., capture images of up to one minute before and after the item occurs.
4. Status monitoring function: It can monitor the situation of important areas and non-control ends such as the locomotive machinery room.
5. Record storage function: 320G storage space, can record and store more than 160 hours of whole process and item audio and video files, and automatically cover.
6. Dump function: real-time dump of item records can be performed through U disk, and data transmission through wireless network to implement dump and real-time monitoring functions.
7. Ground analysis and processing function: the locomotive operation audio-visual data recorded by the on-board host is processed by ground analysis software, and the whole process of locomotive operation is reproduced in the form of intuitive images combined with operating curves, monitoring information and recording, which is a modern safety management and The accident analysis provides real and powerful evidence.
