Abstract
The utility model discloses a power line carrier wave fire detector having emergency lighting, which is provided with a fire detecting sensor. A coding control circuit is connected with the fire detecting sensing circuit and the output of the coding control circuit is connected with a carrier wave sending circuit. The carrier wave sending circuit is connected with a low-voltage power cable through a coupling filtering circuit and an emergency power circuit is connected with the coupling filtering circuit. The coding control circuit is a coding and emergency light control circuit and a LED light emitting emergency lighting circuit is connected with the coding and emergency lighting circuit. When the fire disaster happens, the LED light emitting emergency lighting circuit can be automatically started to illuminate a light emitting diode (LED) and ensure that the people flee for the life and are rescued on the condition of better illuminance, can enhance the safety coefficient and reduce the casualties. The light emitting diode (LED) is characterized in that the power is small and the brightness is high, so the utility model can reach the effects of saving cost and electric energy even though each fire detector is provided with the LED light emitting emergency lighting circuit, compared with the prior art.
Description
Technical field:
The utility model relates to a kind of fire detector, especially a kind of is that communication cable carries out the data carrier transmission and can start the LED luminous lighting automatically when fire takes place with the line of electric force, save cost, saves energy, can improve the power line carrier fire detector with emergency lighting of escape, rescue safety coefficient.
Background technology:
The fire monitoring alarm system all is provided with a plurality of fire detectors (surveying sensing carrier wave transmitter) that are distributed in different places (room) basically, comprise detection sensor (Ion Smoke Sensor sensor, UV fire combustion sensor, infrared fire combustion sensor, combustible gas sensor and temperature sensor or the like), with the encoding control circuit that the detection sensor joins, encoding control circuit then joins by carrier wave transtation mission circuit, coupling filtering circuit and communication cable; Simultaneously also be connected to the reception monitoring host computer that is arranged on Surveillance center with communication cable.Monitoring host computer regularly sends patrols and examines signal, and whether the detection of fires detector is in normal operating conditions and whether fire alarm signal is arranged.When finding that fire alarm signal is arranged, cut off mains supply immediately, start the fire-fighting power source special and report to the police to fire brigade (119) etc.In the past, used communication cable all is client cables or telephone wire etc., characteristics such as power line carrier communication is low with its cost at present, enforcement is convenient, the main means that the fire monitoring alarm system carries out the authentic data communication have been become, the employing FSK modulation-demodulation technique that has, the employing spread spectrum that also has (CHIRP mode) modulation-demodulation technique.Under the normal condition, provide operating voltage for fire detector by the direct supply that obtains after power line transmission power supply transformation, the filtering, when breaking out of fire by providing operating voltage with the emergency power pack circuit that joins of coupling filtering circuit.
The existing greatest problem of existing power line carrier wave fire detector is exactly that self does not have function of emergency illumination.Because existing fire codes requires the essential emergency lighting device of installing, therefore, all emergency lighting devices all are the bigger general lighting lamps of power by the power supply of fire-fighting power source special that is provided with in addition at present, not only install, the use cost height, and, can only in several main thoroughfares few in number, install owing to limited by fire-fighting power source special rated power.In case breaking out of fire does not have the indoor place that waits of emergency light will be very dark, and people's fear is increased the weight of, and brings difficulty for escape, rescue work.
Summary of the invention:
The utility model is in order to solve the above-mentioned technical matters that prior art provides, providing a kind of is that communication cable carries out the data carrier transmission and can start the LED luminous lighting automatically when fire takes place saving cost, saves energy with the line of electric force, can improve the power line carrier fire detector with emergency lighting of escape, rescue safety coefficient.
Technical solution of the present utility model is: a kind of power line carrier fire detector with emergency lighting, the detection sensor is arranged, be connected to encoding control circuit with the detection sensor, the output of encoding control circuit and carrier wave transtation mission circuit join, the carrier wave transtation mission circuit joins by coupling filtering circuit and low-voltage power cable, be connected to the emergency power pack circuit with the coupling filtering circuit, it is characterized in that: described encoding control circuit is coding and emergency lightening control circuit, is connected to the luminous emergency lighting circuit of LED with coding and emergency lightening control circuit.
Described detection sensor is compound fire acquisition sensor.
The utility model is that existing encoding control circuit is designed to coding and emergency lightening control circuit, and join with the luminous emergency lighting circuit of LED, when fire takes place, the luminous emergency lighting circuit of automatically starting LED, make light emitting diode (LED) luminous, make people under the illuminance good conditions, escape, rescue, can improve safety coefficient, reduce casualties.Because light emitting diode (LED) itself has the characteristics that power is little, brightness is high, therefore, compare with prior art, even each fire detector all is provided with the luminous emergency lighting circuit of LED, also can reach the effect of saving cost, saves energy.
Description of drawings:
Fig. 1 is the schematic block circuit diagram of the utility model embodiment.
Embodiment:
Below in conjunction with description of drawings embodiment of the present utility model.As shown in Figure 1: a kind of power line carrier fire detector with emergency lighting, the detection sensor is arranged, be connected to coding and emergency lightening control circuit with the detection sensor, the output and the carrier wave transtation mission circuit of coding and emergency lightening control circuit join, the carrier wave transtation mission circuit joins by coupling filtering circuit and low-voltage power cable, be connected to the emergency power pack circuit with the coupling filtering circuit, coding and emergency lightening control circuit also join with the luminous emergency lighting circuit of LED.The detection sensor can be a simple function, it also can be compound fire acquisition sensor, be about to Ion Smoke Sensor sensor, UV fire combustion sensor, the infrared fiery small module that usefulness multi-layer PCB/SMT technologies such as sensor, combustible gas sensor and temperature sensor are made unified size of firing, according to different detection requirements, small module is carried out two kinds or three kinds of detection mode combinations, to improve detection accuracy and reliability.The same prior art of coded portion in coding and the emergency lightening control circuit, promptly finish with single-chip microcomputer or dsp code processor, emergency lightening control circuit is then judged the detectable signal of importing by single-chip microcomputer, when fire takes place, output signal, start the luminous emergency lighting circuit of LED, make the LED lumination of light emitting diode.
