Digital safeguard video monitoring system for railway train

Abstract

The disclosed system is composed of following parts: (1) camera device in use for taking image information on train, and transferring signal of image to networked digital video server; (2) the networked digital video server in use for receiving each signal, encoding and compressing the received signal to digital signal; sending the digital signal to train digital monitoring terminal, converting signal from the train digital monitoring terminal to analog signal and control signal, which are sent to front end devices; (3) train digital monitoring terminal processes and displays signal from the networked digital video server, and sends control signal to the networked digital video server based on operational commands; (4) transmission part in use for transferring data between the networked digital video server and the train digital monitoring terminal. Monitoring special environment of train, the invention convenient for train staff to solve sudden events in time.

Description

technical field [0001] The invention relates to a video monitoring system, in particular to a digital security video monitoring system for railway trains which can monitor various situations on the trains and prevent emergencies from happening. Background technique [0002] Railways are the main means of transportation for long-distance passengers, and trains are temporary homes for different groups of people. During the journey, there will be various things. In order to ensure the safety of passengers and let them reach their destinations smoothly, the conductor, police, and flight attendants need to keep running in each compartment. However, when emergencies occur, they often Couldn't arrive in time. [0003] The video surveillance system set up on the railway train needs to work under the following conditions and environment: 1. The system equipment works on the high-speed train, and is often under the condition of vibration and impact; 2. The train wagon is not insulate...

Problems solved by technology

During the journey, there will be various things. In order to ensure the safety of passengers and let them reach their destinations smoothly, the conductor, police, and flight attendants need to keep running in each compartment. However, when emergencies occur, they often not in time

[0003] The video surveillance system set up on the railway train needs to work under the following conditions and environment: 1. The system equipment works on the high-speed train, and is often under the condition of vibration and impact; 2. The train wagon is not insulated and should be adapted to summer High temperature and low temperature environment in winter; 3. There is a lot of dust in train operation and passenger windows, and dust prevention measures should be installed; 4. According to the regulations of the Ministry of Railways: adding equipment, the structure of the carriage cannot be changed, and the original wiring of the carriage cannot be changed; 5. Requirements Adapt to the requirements of railway train marshalling operations: the carriages are adjusted to 180 degrees or in series, and the "direction" and "in series" are random and irregular; 6. The power supply of the train is extremely unstable, and the AC variation range is 220V±15%. The DC variation range is 40-80V; 7. Illumination of the carriage: the carriage relies on natural light during the day and lights at night, such as a hard-seat car, or the carriage only has ground lights at night such as a sleeping car; 8. The space of the train compartment is small

Based on the above reasons, there has been no video surveillance system for railway train safety assurance at present, because this is a technical problem that is different from ground monitoring equipment under specific conditions and needs to be solved urgently
