Description
Technical field
The present invention relates to a kind of device of fire-fighting fire disaster escaping guidance system.
Background technology
Along with the quickening of Chinese Urbanization's process, skyscraper, complexity are built more and more general.In the place of many public gatherings, as buildings such as hotel, hotel, nightclub, dancing hall, cinema, small commodity markets, its inner passage is intricate, and personnel's amount of flow is huge.In a single day have disaster (as fire) to take place in these buildings, if do not flee from effective guiding of disaster scene, consequence is with hardly imaginable.Show China's 15.9 ten thousand of breaking out of fires (not comprising forest, grassland, army, mine under ground portion fire) altogether in 2007, dead 1418 people, injured 863 people, more than 9.9 hundred million yuan of direct property loss according to the fire-fighting statistics.Wherein, be total to 8581 of breaking out of fires, dead 156 people, injured 150 people, nearly 186,790,000 yuan of direct losses as markets, hotel, public place of entertainment, hospital of school etc. at crowded place
[1]Complexity is built, how crowded place effectively evacuates the internal staff flees from the disaster scene and organizes the external staff that rescue is arranged, and is the problem that people were concerned about always.
On the one hand, when the emergency of similar this class of fire took place, because the building interior complex structure is full of smoke after the calamity, people were not often because of knowing that in alarm this is toward where escaping.Modal wrong escape mode has: (1) former road escape: this is because people have entered a building of very not being familiar with, and therefore just selects to follow Yuan Lu and flee from when emergency takes place; (2) escape towards light source: walking towards light source is biological natural reaction, but escapes towards light source in the scene of fire, perhaps means to enter a bigger conflagration area; (3) blindly follow: and then the crowd escapes together and might not mean and can find safe escape outlet; (4) take a risk to jump out of the building etc.Cause meaningless casualties because of the escape mode of these mistakes, caused bigger difficulty also for indirectly rescue personnel's disaster relief.On the other hand, after fire takes place, how accurately locating the fire scene, and effectively organize rescue work after the calamity, also is when last big puzzlement.
Summary of the invention

The specific embodiment
Below in conjunction with accompanying drawing the present invention is further described.
With reference to Fig. 1～Fig. 5, a kind of intelligent emergency escape guiding device with function of testing situation of fire, described intelligent emergency escape guiding device comprises: be used for the sensor 1 whether detection of fires takes place; Be used for the signal of pick-up transducers and the signal of sensor is sent to Surveillance center, and the sensor host node module 2 that receives the channeling direction instruction that Surveillance center determines; Escape guiding display unit 3 and power module 4; It is on-the-spot that described sensor 1 and sensor host node module 2 are installed in monitoring, radio communication connects between a plurality of sensor host nodes 2, described sensor host node module 2 is connected with described escape guiding display unit 3, and described power module 3 is connected with escape guiding display unit 3 with sensor 1, sensor host node module 2.
Sensor host node module 2 collect in the network will go after the data A/D conversion wait handle after, can determine the particular location that fire takes place, and the escape algorithm of opening native system carries out the evacuation crowd.The host node module mainly comprises data acquisition module, microprocessor, wireless communication module and four parts of energy supply.
Microprocessor is the calculating core of wireless sensor network node, and all equipment control, task scheduling, energy calculating and orthofunction, communication protocol, data integrate and data dumper all will be finished under its support.
The wireless communication transmissions module adopts the ZigBee technology to finish.This uses the CC2430 radio frequency chip of novel employing TI company and antenna to form.The RF radio frequency chip links to each other with the number control signal line by the SPI interface with microprocessor.Wherein microprocessor is as the main equipment of SPI, and the RF radio frequency chip is from equipment.Microprocessor is responsible for the work of IEEE802.15.4MAC layer and ZigBee part, and applied logic.He is undertaken by spi bus and RF chip alternately.Drive the Smoke Sensor work of front by other control signals.
Escape guiding display module 3 is meant in the escape guidance system and shows best-effort path to the user, takes place on-the-spot so that guide the user to flee from fire fast.In order conveniently to show best-effort path, save cost, will adopt LED display to show the escape guiding path in the native system.Different and the traditional static state of indicating module shows, this indicating module and host node interlock can be according to the demonstration best-effort path of the indication dynamic and intelligent of host node.
Relatively independent module of node indicating module adopts independently the AT89S51 chip to control LED display and shows.How the node indicating module shows that specifically best-effort path comes appointment by the host node module, and this just need provide corresponding interface and host node to realize communicating by letter.
Use 8 data signals to carry out communication between host node module and the LED indicating module, wherein 7 signals are exported to the LED indicating module by the host node module, and 1 signal is imported to the host node module by the LED indicating module.Output signal is meant from the signal of host node module to the output of LED indicating module, the value combination different according to signal, and the LED indicating module is made different demonstrations.Totally 7 of output signals comprise:
EN: enable signal is effectively low.When the EN signal was 0, led module need be made response to following signal; When the EN model was 1, led module need not to respond these signals.
RESET: reset signal is effectively low.When RESET was put 0, led module need turn back to original state, stopped the response to the DATA signal, and put each input signal for its original state; RESET put 1 o'clock, and led module can respond the DATA signal.
DATA[0]: 0 (lowest order) of data-signal DATA.
DATA[1]: 1 of data-signal DATA.
DATA[2]: 2 of data-signal DATA.
DATA[3]: 3 of data-signal DATA.
DATA[4]: 4 (highest orders) of data-signal DATA.
Input signal is meant from the signal of led module to the node module input, is used for the feedback information of led module to node module.Output signal has only 1:
READY: ready signal, effectively high, original state is 0.Led module uses this signal notifying section point module oneself ready, can begin the output signal of receiving node module.
Power unit is mainly given sensor host node, escape guiding display unit and Smoke Sensor power supply, needs+3V ,+5V, three different magnitudes of voltage of+9V.And consider when fire takes place, may to cause the damage of electric power system in the building, so this module also provides standby rechargable battery.In the design's power supply, give the voltage of system+5V by transformer module, a part is used for the thread charging of battery, another part is used to control the work of DC-DC module, and export+5V and+9V is respectively that LED shows and sensor is powered; When civil power was disconnected, battery was used for controlling the work of DC-DC module.Because it is energy-conservation that node three big modules are all accomplished as far as possible, in taking place, adopt fire storage battery power supply to have satisfied the demand substantially like this.So just realized the uninterrupted power supply of whole system, made that WSN also can operate as normal when fire takes place.
