Subway Tunnel Emergency Location

1. System Introduction

The subway tunnel once an accident occurs, the current location and other related systems have been paralyzed. This system uses geomagnetic inertial navigation positioning technology for real-time tracking of rescue personnel into the tunnel external position, while the position of real-time transmission of rescue personnel to the ground monitoring command center, the ground command personnel dispatched convenient command scheduling according to the real-time location of rescue personnel.

2. System Characteristics

2.1.Random walk subway tunnel rarely, so there is no need to establish the base station positioning system normal, but once an accident occurs, an emergency rescue system, without any deployment of equipment.

2.2. Subway tunnel disaster once accidents in general are disastrous accidents, the normality of base station positioning system has been the inevitable paralysis, need a set of emergency rescue system, and does not require any deployment of equipment.

2.3. Interference of tunnel is a special and harsh environment, radio signal transmission attenuation, GPS signal can not cover the tunnel, this requires a set of emergency rescue system, the system can solve the problem of signal interference, real-time positioning.

3. The System Composition and Working Principle

The LongCheer spectrum subway system consists of three parts: wireless micro positioning device, wireless terminal, wireless signal relay, personnel positioning 3D display platform.

3.1. Wireless micro positioning device: the main wear of the wireless device has the advantages of small volume on the user, the battery, power supply. The main internal device for identification card, identification card using inertial navigation module and wireless transmission module. The inertial navigation module can be important parameters for real-time monitoring of the current identification card displacement distance, direction angle, the height and inclination etc.. At the same time, a variety of related parameters through the "send wireless transmission module to the server".

3.2. Wireless receiving terminal: wireless receiving terminal equipment for the main "wireless receiving module", the module and the positioning device identification card "wireless transmission module" is relative, mainly used to accept all kinds of important data transmitted from the transmitting module, and for storage and analysis.

3.3. Positioning three-dimensional monitoring platform: three-dimensional monitoring platform based on wireless receiving personnel location related parameters of terminal transmitted, using a combination of mathematical model and 3D graphics, calculate the location and display the location, staff and staff attitude trajectory in the three-dimensional monitoring service platform.
