1.System Introduction

A special system for emergency rescue department of research and development, it does not require any additional infrastructure or network, walking distance and direction information wirelessly to the real-time output of personnel, can realize the accurate positioning of personnel in various complex environments, In order to provide effective guarantee the life safety of personnel.

2.The Function of the System

2.1.The building of 3D basic functions: to implement 3D building, zoom translation, rotating and positioning function.

2.2. Personnel three dimensional positioning: according to the three-dimensional parameters of personnel positioning equipment transmission back The personnel positioning personnel positioning equipment wear.

2.3. Personnel trajectory simulation: according to the three-dimensional parameters of personnel positioning equipment transmission back in 3D architecture to implement human walking trajectory real-time dynamic simulation, Each track using a color.

2.4. Personnel basic information display, view the personnel in the building of internal distribution, and The basic information and personnel.

2.5. staff attitude information monitoring: To implement personnel attitude monitoring, including static, walking, running, down, up and down the stairs posture monitoring.

2.6. State personnel information monitoring: The realization of personnel monitoring, Including body temperature, pulse, heartbeat and other signs of data.

2.7. the information of Fire fighting equipment: Can see inside a building fire fighting equipment distribution.

2.8.The realization of personnel search and rescue team, Safety exit guide, Oxygen countdown, The gas alarm.

4. Product Innovation:

4.1. Positioning Innovation

Using a variety of correction algorithm, improve the indoor positioning accuracy of inertial navigation.

Indoor positioning technology mainly in the traditional base station positioning, advance deployment of base stations in the indoor environment, such as the WIFI RFID hot spots, and so on the receiving end of base station, and then by using triangulation algorithm for coordinate calculation. This pattern in each building (coal mine), each floor of the deployment of base station equipment, both the government and the enterprises invested a lot of manpower and financial resources for building construction, maintenance, resulting in serious social costs, due to appear in a building fire disaster, the general need to turn off the power, not lead to base station technology used in emergency rescue.

The traditional inertial navigation positioning technology due to magnetic interference, in the indoor environment as a result of cumulative error positioning accuracy can not be applied to emergency rescue.

After years of research and testing project team, using a variety of correction algorithm, eliminate inertial magnetic interference and error accumulation problem, can be really used in indoor positioning.

4.2. Wireless Communication Innovation

The traditional indoor positioning using WIFI, ZIGBEE, RFID and other indoor short distance wireless communication, the project team through continuous testing, testing a variety of scenarios, using a point of low-frequency transparent transmission, realize emergency wireless communication can cover 50 floors, ensuring timely monitoring positions.

4.3. 3D Display Innovation

Indoor positioning tradition mainly adopts two ways, one is the trajectory of a free apartment layout display, is a two-dimensional trajectory show apartment layout. Because when the emergency rescue command staff, more concerned about the apartment layout structure, escape, export, emergency equipment, water and other accessory position information, if there is no apartment layout structure, just track line, the command staff not clear where is the exit, can not find the exit command show timely escape, if you don't know the escape, to guide soldiers dead aisle. The two-dimensional structure apartment layout more difficult, and more suffering, not intuitive.

The 3D construction and display module using this system, the specific structures of 3D modeling in a relatively short period of time. At the same time the display terminal can realize translation, scaling, rotating and positioning function of 3D model construction, so as to achieve the browsing of buildings in different parts of visual navigation. Can the first time to see the staff in the building of internal distribution, and all staff have their own numbers, each number corresponds to the relevant rescue personnel basic information, in order to facilitate the on-site command scheduling and control. At the same time also can accurately check the emergency equipment distribution inside a building, each device's basic information and status information, to facilitate command and rescue personnel in the rescue process to enable timely.
