Embodiment approach 1

[0031] refer to figure 1 , the dispatching and monitoring system for railway emergency rescue and dynamic video monitoring basically includes five basic components: terminal equipment, wireless router WR (EWR), intelligent access node IAP, wired transmission network and mobile switching control center MiSC (network management center) network unit. The terminal equipment includes a camera and an emergency communication box (emergency box), and the camera is connected to the emergency box. Emergency case includes codec, transmission equipment and batteries. Among them, the IAP and WR can use the equipment that meets the following technical conditions:

[0032] IAP index: Working frequency: 2.4GHz

[0033] Modulation method: DSSS (Direct Sequence Spread Spectrum)

[0034] Transmission power: 25dBm (maximum)

[0035] Power Consumption: 12W

[0036] Power supply: 220V / 50Hz

[0037] Size: 15.9cm×15.9cm×10.2cm

[0038] ...

Embodiment approach 2

[0052] Similar to Embodiment 1, the dispatching monitoring system for railway emergency rescue and dynamic video monitoring basically includes terminal equipment, wireless router WR (EWR), intelligent access node IAP, wired transmission network and mobile switching control center MiSC (i.e. Network management center) 5 basic network units. The terminal equipment includes a monitoring camera and a wireless router (WR or EWR) connected to it, which only needs a mains power supply and does not need other wired channels, which is conducive to the convenient and quick arrangement of monitoring points, such as crossings, Flood control points, rockfall points, locomotive cabs, passenger compartments, etc. The video data monitored by the camera is forwarded to the adjacent IAP through the EWR route, and then transmitted to the electronic screen of the dispatch center (that is, the command center) through a wired channel. The center, wired transmission network, intelligent access poin...

Embodiment approach 3

[0056] Corresponding to Embodiments 1 and 2, the present invention also provides a dispatching and monitoring method for railway emergency rescue and dynamic video monitoring, which includes the following steps: 1. Arranging the terminal equipment at the emergency rescue location; 2. The camera included in the terminal equipment is aimed at the emergency scene, and the terminal equipment also includes an emergency communication box; 3. The camera is connected to the emergency box, and the emergency box includes a codec, a transmission device and a battery; 4. The camera will The on-site video image is encoded in real time by the codec in the emergency box, and the encoded video data is forwarded to the adjacent intelligent access point IAP through the wireless router; 5. The intelligent access point IAP is transmitted to the mobile exchange through the wired transmission network On the electronic screen wall of the control center; 6. The mobile switching control center transmit...

Abstract

This invention relates to a dispatch monitor system for railway emergency and dynamic video monitor including a terminal device, a radio router, intelligent access node IAP, a wire transmission network and a mobile switch control center, in which, the terminal device includes a camera and an emergency communication box connected with the camera, said emergency box includes a code / decode device, a transmission device and batteries, said camera codes the site video images by the code / decode device in the box timely, then the coded video data are forwarded to the close IAP via a radio router to be transmitted to an electronic screen wall of a mobile switch control center via a wire transmission net, the center delivers related information to terminal displays in cabs via wire transmission nets, IAP and radio routers and a monitor method is also disclosed.

Description

technical field [0001] The present invention relates to a dispatching and monitoring system and method for railway emergency rescue and dynamic video monitoring, in particular, it relates to a system and method for transmitting railway data, images and voices using a 2.4GHz wireless broadband data transmission mode. Background technique [0002] With the 5th speed increase of my country's railways and the opening of intercity direct trains, it marks the continuous improvement of railway transportation equipment and technical level, but there are still deficiencies in railway passenger services, emergency rescue communications, and dynamic video monitoring to ensure driving safety. [0003] In terms of emergency communication: the current emergency communication equipment is huge, complex in structure, difficult to carry, connect and maintain, and takes a long time to open, which cannot meet the basic requirements of light, flexible, quick activation, and simple maintenance. ...
