Principle of work of the present utility model:
The utility model comprises acceleration transducer and fire perceiving device, hyperacoustic range sensor, a series of sensors of indoor positioning sensor, high-decibel alarm, rescues terminal, wireless communication module and backstage central server module;
Sensor section is made up of acceleration transducer, ultrasonic distance sensor, fire perceiving device, indoor positioning sensor, all pass through IO mouth be connected with wireless communication module form wireless sensor network node; Wherein acceleration transducer is installed on the top of building and sets corresponding threshold value according to floor height, in the time there is earthquake, building swing and produce acceleration, in the time that accekeration exceedes threshold value, be judged as that earthquake occurs and data passed back to backstage central server module trigger alarm device by wireless communication system and send high-decibel warning, backstage central server module trigger sensor network and positioning system enter mode of operation simultaneously.Do not repeat therefore fire perceiving device working method and acceleration transducer are similar, fire perceiving device is back to backstage central server module by environment temperature and smokescope by wireless sensor network in the time that fire occurs simultaneously.Ultrasonic distance sensor is started working after earthquake or fire generation, and mainly, to measure the mode of corridor through path length, the passability that detects corridor is also back to backstage central server module by data; Indoor positioning sensor is integrated in the rescue terminal that user wears, and realizes location and identity identification in real time by RFID positioning system, and relevant information will be back to backstage central server module by wireless communication system;
Center background server module, comprises login management interface module, data analysis module, optimal path computation module and network communication module.Login management interface module, for login management rescue center background server and escape system, data analysis module is for arranging and analyze the data that receive, optimal path computation module is calculated by related algorithm for the data that data analysis module is arranged, for each user calculates an optimum best-effort path, network communication module is used for receiving the data from wireless communication system, and optimum best-effort path is passed back in user's rescue terminal by wireless communication system.
All wireless sensor network nodes all adopt the mode of power supply adaptor and rechargeable battery collaborative work to power, and are similar to corridor emergency light, are powered under normal circumstances by power supply adaptor, in the time that disaster causes power-off, are powered by rechargeable battery;
The vibration signal that acceleration transducer produces earthquake is converted to electric signal, and electric signal is converted to digital signal by the A/D function of single-chip microcomputer by analog electrical signal.If earthquake occurs, the first wireless communication module reaches center background server module by cordless communication network by signal and data, and center background server module triggers whole network and enters mode of operation;
The continuous testing environment temperature of fire perceiving device and smokescope, the first wireless communication module contrasts itself and threshold values to judge whether breaking out of fire.If fire occurs, the first wireless communication module reaches center background server module by cordless communication network by signal and data, and center background server module triggers whole network and enters mode of operation;
After disaster occurs, the second wireless communication module reads environment temperature and the smokescope that length that range sensor returns and fire perceiving device return, compare with the threshold value setting in advance, if length is less than threshold value or smokescope and is greater than threshold value and illustrates that this section of road is obstructed, otherwise this section is described, the road is clear, then result is sent to backstage central server module by cordless communication network;
Locating module is mainly made up of reader and active label, and reader and active label use CC2530 chip formation RFID communication system, and active label is connected and controlled liquid crystal indicator and warning device formation rescue terminal by IO mouth simultaneously.System start working after reader launch activation signal to label, label is received after activation signal in state of activation, information in label is sent to the reader in its communication range, reader receives after label information, and the received signal strength RSSI value of equipment of itself address, label information and this information is sent to backstage central server module by cordless communication network.The signal intensity RSSI value of the same active label that backstage central server module receives by the multiple readers of comprehensive analysis, interpretation goes out the particular location (i.e. the position of the reader nearest with it) of active label;
Backstage central server module adopts Windows as underlying operating system, comprises login management interface module, data analysis module, optimal path computation module and communication module.Login management interface module presents with the form of graphic user interface, realizes the control to whole escape system and management intuitively.In the passage situation in each section that data analysis module is passed cordless communication network back and building, the position at personnel place builds topological model.The topological model data that optimal path computation module synthesis data analysis module builds, using optimal path algorithm is that every personnel calculate optimum best-effort path.Backstage central server module is connected with wireless communication system module by serial ports and forms network communication module, accept the data that cordless communication network passes back and the optimum best-effort path that backstage central server module is calculated sends to rescue terminal by cordless communication network, rescue terminal, on its display screen, optimal path is shown to guide personnel escape in building.
The above is only to preferred embodiment of the present utility model, not the utility model is done to any pro forma restriction, every foundation technical spirit of the present utility model is to any simple modification made for any of the above embodiments, equivalent variations and modification, all belong in the scope of technical solutions of the utility model.
