The specific embodiment
Below in conjunction with accompanying drawing and embodiment the present invention is explained further details.
As shown in Figure 1, the fire disaster intelligently escape system that the present invention is based on the zigbee technology comprises zigbee wireless location subsystem, telemanagement subsystem and escape direction indication subsystem.
As shown in Figure 2, the zigbee wireless location subsystem in the escape system of the present invention comprises zigbee wireless locating module (can adopt the cc2431-F128 of Texas Instrument (TI)), temperature and Smoke Sensor module (can adopt Anne's Weir PT-602PC), zigbee center base station module (can adopt the cc2533 of Texas Instrument (TI)) and the automatic charging module of battery (can adopt the AC-DC of Song Chuan Electrical Appliances Co., Ltd charging module).
Telemanagement subsystem in the escape system of the present invention comprises base station and computer.When fire takes place, as long as be placed on base station near the scene of fire, cooperate notebook computer, just can reflect scene of fire personnel's distribution situation.Base station be responsible for zigbee wireless location subsystem in the contact of zigbee center base station module.
Zigbee wireless location subsystem is arranged on the path of scene of fire escape way in advance, according to the concrete condition in path, whenever at a distance from 20 ~ 30 meters fixing cover zigbee wireless location subsystems.In the existing fire safety facility, it is the national standard of executing that the escape way emergency exit indicates, and zigbee wireless location subsystem volume of the present invention is little, and the space and the power supply that can utilize existing escape way outlet to indicate fully needn't rewirings.In this subsystem, be furnished with the automatic charging module of battery, after outage, can supply power voluntarily more than 100 hours.Whole building space zoning territory, each zone is provided with a zigbee center base station module and is in charge of this regional zigbee wireless location subsystem and gets in touch with base station.Zigbee center base station module sends to base station to the personnel positions that collects.Through the operating point that zigbee wireless location subsystem is arranged, can in computer, set up the space map of this building of cover, when fire took place, zigbee wireless location subsystem can send to escape direction indication subsystem to escape route.The temperature of this subsystem and Smoke Sensor module are in resting state when not having fire alarm signal.When fire alarm signal triggered, this module was started working, and the temperature of collection site and smog parameter.If the parameter value of gathering is in safe range, the expression this area can be used as escape route.If the parameter value of gathering exceeds safe range, represent that then this area can not be as escape route, and send to escape direction indication subsystem to signal, plan escape route again.Zigbee centre base station sends to base station to the personnel positioning information that receives, and base station and computer are got in touch, and can understand the personnel's distribution situation in the scene of fire, so that planning relief scheme is taked the measure of effectively succouring.
As shown in Figure 3, the escape direction indication subsystem among the present invention comprises zigbee wireless receiving module (can adopt the cc2431-F128 of Texas Instrument (TI)), MSP430 central processing unit, gyro module (can adopt ADXRS gyroscope chip), 2DOF motor stand (can adopt homemade), laser projecting apparatus (can adopt the PicoP of Microvision company) and power module (can adopt the DC-DC of Song Chuan Electrical Appliances Co., Ltd power module).
Escape direction indication subsystem is fixed on the mouth front end of protection from fumes face shield.When breaking out of fire; The survivor wears the protection from fumes face shield; System will move the entering duty automatically; Zigbee wireless receiving module in the escape direction indication subsystem receives the framing signal that zigbee wireless location subsystem sends, and with green laser icon mode, projects ground to survivor's escape direction.
After escape direction of the present invention indication subsystem receives the framing signal that certain zigbee wireless location subsystem sends; To carry out this index point location; Send this direction that indicates point to the MSP430 central processing unit, the MSP430 central processing unit locks target direction, and sends to gyro module to the angle of locking direction; By the change angle of gyro module control 2DOF motor stand, it is constant to make 2DOF motor stand remain locking direction.That is to say; No matter how survivor's head changes; Being fixed on laser projecting apparatus on the 2DOF motor stand, to remain locking direction constant, and the green laser escape direction of being throwed indicates and also remains unchanged, and the survivor just can observe the escape direction of oneself at any time like this.
Embodiment:
Arrange several zigbee wireless locating module at each floor, can cover main thoroughfare and outlet at least.On plane, couple together these points, can depict the basic structure of whole floor.A main feature of the present invention can be planned escape route clearly for the survivor exactly.
As shown in Figure 4, this is the zigbee wireless location subsystem distribution situation sketch map of a floor.In several zigbee wireless locating module of each channel arrangement, each zigbee wireless locating module distance can not that is to say that greater than the self radio transmission range transmission range of per two zigbee wireless transport modules will have common factor.Each zigbee wireless locating module has unique title, and A01001 ~ A01025 is 25 zigbee wireless locating module, and A01022 for example is illustrated in No. 22 zigbee wireless locating module in Building 1, A district, building.In a certain position of floor, a zigbee center base station module is set, the zigbee wireless locating module of whole floor is wanted to cover in the position of setting, and can keep wireless communication with the zigbee center base station module of other floors.
The distribution map of the zigbee wireless location subsystem of whole building is transfused in the computer software, and when the breaking out of fire dangerous situation, whole system will be moved automatically.Zigbee wireless location subsystem detects this floor personnel distribution situation, plans escape route automatically.
Such as; Room 109 have the people to need escape, and Room 109 have 5 to the escape route of the extra exit of this floor, according to the concrete condition of fire; 1., 2., 4., the condition of a fire is all arranged on 5. the escape route; After the temperature of zigbee wireless location subsystem and Smoke Sensor detect the condition of a fire, be transferred to signal in the systems soft ware, finally confirm the 3. the bar route be escape route.
After the escape personnel of Room 109 wears the protection from fumes face shield, system will move automatically.The personnel of Room 109 can receive on every side the signal that a plurality of zigbee wireless location subsystems of being provided with are sent, but the signal that system only selects the zigbee wireless location subsystem of escape route to be sent.When the personnel of Room 109 go to this place, doorway, room; A01020 wireless location subsystem is confirmed personnel positions information; A01018 wireless location subsystem will provide escape personnel's escape direction; And guide the survivor to advance to the A01012 direction, guide through A01008 → A01004 → A01003, up to arriving the extra exit.
After confirming good escape route, send to this escape route in the escape direction indication subsystem.The zigbee wireless receiving module receives instruction, after the MSP430 processor processes, sends to the ADXRS gyro module to concrete escape direction.ADXRS gyro module control 2DOF motor stand makes the laser projecting apparatus that is fixed on the motor stand point to escape direction all the time.Like this, it is constant that the green arrow that laser projecting apparatus projects ground points to escape direction all the time, and the influence that does not receive the survivor to move and rock with brains.The survivor can observe escape direction easily at any time, obtains correct relief in time.
