It is uniformly arranged the setting blade vertical with boss side surfaces between some smoke intaking holes, adjacent smoke intaking hole；Circuit board include single-chip microcomputer,
Smoke detection circuit, temperature sensor and the external signal of connection single-chip microcomputer access circuit respectively.
Further improvement of the utility model is：The smoke detector includes infrared transmitter, infrared remote receiver, company
Connect the filter amplification circuit of infrared remote receiver, connect the comparison triggers circuit of filter amplification circuit, compare triggers circuit connection single
Piece machine.
Further improvement of the utility model is：Thermometer hole is set on the shell, and temperature sensor passes through thermometer hole
Stretch out housing exterior.
Further improvement of the utility model is：Power supply indicator and alarm lamp, electricity are set on the lid of shell
Source indicator lamp and alarm lamp connect single-chip microcomputer respectively.
Further improvement of the utility model is：Buzzer, buzzer connection single-chip microcomputer are also set up on shell.
Further improvement of the utility model is：A diameter of 80 ~ 110mm of enclosure bottom, outer cover height be 40 ~
60mm, the quantity of smoke intaking hole is 8 ~ 12.
Because the beneficial effect produced by using above-mentioned technical proposal, the utility model is：
The utility model transmits signal by two wire bus, can not only realize fire alarm on tunnel internal road
Detection, while different contents can be transmitted to Surveillance center according to the unlike signal of access external signal access circuit.When outer
The information such as portion's signal access circuit transmission power supply signal, smoke detection signal, stable detectable signal are to Surveillance center.
Temperature sensor of the present utility model is capable of the change of detection temperature, with reference to Smoke Detection, it is ensured that detection
Accuracy.Blade can guide smog to enter simultaneously also can shading, it is ensured that it is accurate that smog is measured.
Power supply indicator of the present utility model can indicate energization situation, damaged in power line or other situations cause power-off
When can find in time, ensure normal operation of the present utility model, found in time during generation fire.
Alarm lamp and buzzer of the present utility model can send sound and light alarm, and finger can be sent when occurring fire
Show and sound prompting personnel escape and the disaster relief.
