Description
Technical field
The utility model relates to rescue field, the scene of a fire, particularly relates to a kind of search equipment for scene of a fire rescue.
Background technology
Rescue search equipment in the scene of a fire of the prior art often adopts sound or light to report to the police, rescue worker's rootThereby find fireman in danger according to sound or light. But, under complicated site environment, as high noisy,In the buried situation of low visibility or fireman, rescue personnel just cannot judge fast fireman in danger accuratelyPosition.
Utility model content
Utility model object: the purpose of this utility model be to provide a kind of be applicable to complex environment, judging nicety rateThe high search equipment for scene of a fire rescue.
Technical scheme: for reaching this object, the utility model by the following technical solutions:
A kind of search equipment for scene of a fire rescue described in the utility model, comprises that sender unit and signal connectReceiving apparatus, sender unit comprises wireless pressure transmitter and search and rescue signal amplification module, wireless pressure transmitterComprise baroceptor, acceleration transducer, the first wireless communication module and first processor; Baroceptor is adoptedThe air pressure numerical value of collection fireman's gas cylinder is also passed to first processor, acceleration transducer Real-Time Monitoring fireman's fortuneMoving state is also passed to first processor, and when acceleration transducer, to monitor the time that fireman remains static superWhile crossing default thresholding, first processor control the first wireless communication module is launched air pressure numerical value, works as accelerationThe time that Sensor monitoring remains static to fireman, while exceeding default thresholding, letter was searched and rescued in first processor controlNumber amplification module starts, and controls the first wireless communication module and continue to send original distress signal to search and rescue signal and amplifyModule, search and rescue signal amplification module amplifies rear formation distress signal and launches original distress signal, letterNumber receiving system is for receiving the signal of sender unit transmitting.
Further, when monitoring the time that fireman remains static, acceleration transducer do not exceed default thresholdingTime, first processor control the first wireless communication module adopts normal working frequency to launch air pressure numerical value; WhenAcceleration transducer monitors time that fireman remains static while exceeding default thresholding, first processor controlThe first wireless communication module adopts special rescuing frequency that original distress signal is continued to be sent to search and rescue signal amplification mouldPiece; Signal receiving device is monitored distress signal in special rescuing frequency.
Further, described special rescuing frequency is 2498MHz.
Further, described signal receiving device comprises that the second wireless communication module, the second processor and LCD show mouldPiece; The second wireless communication module receives the signal of sender unit transmitting, processor control LCD display module pairThe signal that the second wireless communication module receives shows.
Further, described default thresholding is 1 minute.
Beneficial effect: the utlity model has following beneficial effect:

(2) the utility model adopts acceleration transducer, and fireman's motion state is carried out to Real-Time Monitoring, energyEnough automatic decision firemans' state in danger, automatically starts search and rescue signal amplification module original distress call is amplified to shapeBecome distress call and launch, having shortened distress period in emergency circumstances;
(3) the utility model adopts signal receiving device distress call is received and show, rescue personnel canWith hand-held signal receiving device, under the complex environment of dark, dense smoke or high noisy, judge rapidly and accurately in dangerFireman's azimuth-range, has improved rescue ability;
(4) the utility model volume is little, easy to carry, simple to operate, and reliability is high, can be widely used inMultiple fields such as fire-fighting, people's air defense, chemical defence and anti-terrorism.
Brief description of the drawings
Fig. 1 is the block diagram of sender unit of the present utility model;
Fig. 2 is the block diagram of signal receiving device of the present utility model.
Detailed description of the invention
Below in conjunction with detailed description of the invention, the technical solution of the utility model is further introduced.
The utility model discloses a kind of search equipment for scene of a fire rescue, comprise that sender unit and signal connectReceiving apparatus.
Sender unit as shown in Figure 1, comprises wireless pressure transmitter and search and rescue signal amplification module, without line pressurePower transmitter comprises baroceptor, acceleration transducer, the first wireless communication module, first processor, power supplySwitch and power supply. The air pressure numerical value of baroceptor collection fireman's gas cylinder is also passed to first processor, accelerationSensor Real-Time Monitoring fireman's motion state is also passed to first processor, when acceleration transducer monitors fire-fightingThe time that member remains static, while not exceeding default thresholding, first processor control the first wireless communication module adoptedNormal working frequency is launched air pressure numerical value, and when acceleration transducer monitors, fireman remains staticTime, while exceeding default thresholding, first processor control search and rescue signal amplification module started, and controls the first channel radioLetter module adopts special rescuing frequency to continue to send original distress signal to search and rescue signal amplification module, and search and rescue signal is putLarge module is amplified rear formation distress signal and launches original distress signal, power switch for opening orPerson's powered-down, power supply is used for to baroceptor, acceleration transducer, the first wireless communication module and the first placeThe power supply of reason device. Wherein, normal working frequency is 2400-2476MHz frequency hopping, and special rescuing frequency is 2498MHz,Default thresholding is 1 minute.
Signal receiving device as shown in Figure 2, comprises that the second wireless communication module, the second processor and LCD show mouldPiece, LCD display module comprises LCD display. The second wireless communication module connects by highly sensitive directional aerialReceive the signal of sender unit transmitting, processor control LCD display module receives the second wireless communication moduleSignal shows. Signal receiving device is monitored distress signal in special rescuing frequency, if listen to correctDistress signal, is just presented at signal strength signal intensity on LCD display. Rescue personnel's rotational orientation antenna, by observingThe numerical value change of signal strength signal intensity, can judge direction and the distance of signal source.
