Description
Technical field
The utility model relates to a kind of smoke sensor.
Background technology
Occupy considering of security against fire traditionally, have many indoor places all smoke sensor can be installed, then installation site or the power connection of smoke sensor are not usually reserved for many old-fashioned buildings.Even if there is the smoke sensor of fixed form also not to have wireless or wired ability to communicate in addition, just give a warning function mostly, or connect sprinkling filter carry out smoke sensing after spread water function.This product is applicable to the fire alarm in the places such as household, shop, dancing hall, warehouse.The process on fire of fire is generally with cigarette, heat, light three kinds of products of combustion.At Initial Stage of Fire, because temperature is lower, material many places in the stage of glowing, so produce a large amount of smog.Smog is one of key character of incipient fire, smoke fire detector utilizes this feature and develops, and it can be the change of detection position smokescope is converted to electric signal realize a kind of device of warning object to the fire detector of visible or sightless smoke particle response.
But there is poor anti jamming capability, low precision in existing smoke sensor, the shortcomings such as measurement result is unstable.
Utility model content
In view of this, the utility model provides a kind of smoke sensor, not high in order to poor anti jamming capability, the measuring accuracy solving the existence of existing smoke sensor, the shortcoming of measurement result instability.
The utility model is solved the problems of the technologies described above by following technological means:
A kind of smoke sensor of the present utility model, comprise measurement mechanism and output unit, described measurement mechanism comprises light-emitting device, described light-emitting device front is provided with spectroscope, described spectroscope front is provided with measuring chamber and calibration chamber, lens are provided with in described measuring chamber and calibration chamber, optical sensor is provided with before described lens, described optical sensor is connected with photoelectric commutator, described photoelectric commutator is connected with modulus conversion chip, described output unit comprises radio transmitting device and warning device, described modulus conversion chip is connected with radio transmitting device and warning device.
Further, described calibration chamber is provided with screen pack, described measuring chamber and calibration chamber are provided with back-blowing device.
Further, outside fly net is also comprised.
Further, described measurement mechanism is also provided with temperature sensor.
Further, described light-emitting device is semiconductor laser.
Further, also camera is comprised.
The beneficial effects of the utility model: a kind of smoke sensor of the present utility model, owing to being designed with measuring chamber and calibration chamber, can correct by real-time carrying out, thus avoid ambient temperature or illumination etc. to fluctuate the noise caused, improve anti-interference, measuring accuracy is high, is designed with back-blowing device, avoid the equipment Inspection error that dust or the accumulation of solid particle on smoke sensor cause, measurement result is stablized.
