Description
Technical field
The invention belongs to electronic technology fields, are applied in electric system, especially set and a kind of cable duct fireproof monitoring fills
It sets.
Background technology
Currently, most of substations are all unattended substations, and after substation puts into operation, the core band of cable
Electricity, prolonged electrification may lead to electric cable heating, and further development can then lead to Ignition Phenomena, if fire occurs for cable duct
Calamity, since the inside of cable does not install monitor video or installation monitoring device, operation monitoring personnel is to be unable to monitor fire
, if fire behavior enters canyon by cable duct or primary equipment is in-house, it will lead to primary equipment and secondary
The protection of canyon is burnt, to which more serious accident occur.Currently, being only mounted with the fire of secondary device room inside substation
Calamity monitoring device, there is no being monitored to the fire of cable duct, although fire wall is arranged in many places, effect is not very bright
It is aobvious, therefore, for this phenomenon, it is very necessary specially to make a kind of device that can monitor cable duct fire.
Invention content
It is an object of the invention to overcome the deficiencies in the prior art, and provide a kind of cable duct fireproof monitoring device,
The present invention solves its technical problem and following technical scheme is taken to realize：
A kind of cable duct fireproof monitoring device, including the data collection terminal of data processing CPU, CPU are identical as multigroup composition
Sensor unit connection, the data output end of CPU respectively with temperature anomaly exit relay, urgent warning exit relay and
Start the connection of FIRE EXIT relay, control the state of above three exit relay,
Wherein, sensor unit includes temperature sensor and smoke sensor device, and each sensor unit is installed in
Below the cable well lid of leader cable ditch and interval cable T shape interfaces, the power unit of sensor unit is mounted on the remittance at interval
It controls inside cabinet；
Wherein, the data processing method steps of the CPU are：
(1) start-up temperature sensor sample；
(2) sensor acquisition signal is amplified processing；
(3) normal temperature value and normal smog value in cable duct are set in CPU, by the temperature value of acquisition and positive room temperature
Angle value is compared, and if it is less than normal temperature value, temperature value acquisition is returned to, if the temperature value of acquisition is more than normal temperature
Value triggers temperature anomaly exit relay, externally sends out temperature anomaly signal, while starting smoke sensor device sampling；Smog passes
The smog value of acquisition is compared with normal smog value after starting sampling for sensor, if it is less than normal smog value, returns to smog
Value acquisition, if acquisition smog value be more than normal smog value, trigger emergency alarm exit relay and start FIRE EXIT after
Electric appliance externally sends out emergency alarm, while starting fire-fighting system work.
Moreover, the sensor unit specifically includes thermal resistance sensor and ardometer.
The advantages and positive effects of the present invention are：
Using apparatus of the present invention alarm signal is sent out in time, when cable duct temperature when the cable temperature exception of cable duct
When exception monitors smog simultaneously, starts fire-fighting system while the number of delivering letters on backstage, can not only remind monitoring in this way
Personnel, while fire-fighting fire extinguishing can be automatically carried out, to greatly increase the safe and stable operation of unattended operation transformer station.

Mode acquire the temperature data in cable duct.
Wherein, as shown in Fig. 2, the method and step of temperature data is in CPU processing cable ducts：
(1) start-up temperature sensor sample,
(2) due to the output analog quantity very little of sensor, so needing sensor signal being amplified processing；
(3) normal temperature value and normal smog value in cable duct are set in CPU, by the temperature value of acquisition and positive room temperature
Angle value is compared, and if it is less than normal temperature value, temperature value acquisition is returned to, if the temperature value of acquisition is more than normal temperature
Value triggers temperature anomaly exit relay, externally sends out temperature anomaly signal, while starting smoke sensor device sampling；Smog passes
The smog value of acquisition is compared with normal smog value after starting sampling for sensor, if it is less than normal smog value, returns to smog
Value acquisition, if acquisition smog value be more than normal smog value, trigger emergency alarm exit relay and start FIRE EXIT after
Electric appliance externally sends out emergency alarm, while starting fire-fighting system work.
