Temperature sensor, smoke transducer, microprocessor, power module, communication module etc. Constitute the monitoring sub -station, the signal acquisition module is responsible for receiving the monitoring data signal that the various terminals of monitoring sensor transmits back, communication module is responsible for gather the terminal signaling and terminal fault -signal transmits to the main website, whether the main website exceedes the predetermined threshold value of reporting an emergency and asking for help or increased vigilance through the information magnitude of judging each sub -station and beaming back, fixes a position conflagration or whole trouble terminal position fast to start corresponding early warning and aid decision. The utility model is suitable for an unattended substation's cable pit conflagration on -line monitoring.
Description
Technical field
The utility model relates to a kind of cable duct of substation fire on-Line Monitor Device, belongs to power system automation technology field.
Background technology
Transmission of electricity in transformer station and distribution line turnover transformer station generally adopt cable through cable duct system of laying, for saving the area and construction cost, and general one or several cable duct shared.Cable is embedded in underground by cable duct, once breaking out of fire is difficult to find, particularly transformer station is generally unmanned at present, once often need after breaking out of fire just to find by fire alarm or other modes for a long time, now in cable duct, numerous power cable is in damaged condition, cause occurring power-off event on a large scale, have a strong impact on the power supply reliability of power supply enterprise.
Summary of the invention
The purpose of this utility model is, in order to realize cable duct of substation fire Real-Time Monitoring, thus process fire in time, avoid causing power-off event on a large scale because of numerous power cable scaling loss, a kind of device based on technology of Internet of things, cable duct of substation fire condition being carried out to Real-Time Monitoring is provided.
The technical solution of the utility model is, a kind of cable duct of substation fire of the utility model on-Line Monitor Device comprises monitoring terminal and cable duct fire on-line monitoring main website; Monitoring main frame is connected with monitoring terminal by Internet.
Monitoring terminal in described device comprises temperature sensor, smoke transducer, microprocessor, power module, communication module.Temperature sensor and smoke transducer access the input end of microprocessor respectively by A/D converter, the output terminated communications module of microprocessor, and power module connects microprocessor also to its power supply.
Temperature sensor and smoke transducer are arranged in cable duct, determine according to actual needs to install quantity and concrete installation site, can Real-Time Monitoring present position environment; The signal of microcontroller acquires sensor collection is gone forward side by side row relax, and communication module adopts Internet of Things self-organized network communication mode, and signal microprocessor processes can crossed and terminal heartbeat message are sent to cable duct fire on-line monitoring main website.Power module provides power supply for monitoring terminal, adopts CT power taking to add lithium battery mode, under normal circumstances by being buckled in the CT power taking on power cable, if power cable stoppage in transit maintenance situation is by lithium battery maintenance work.
Fire on-line monitoring main website in described device comprises industrial control host, signal acquisition module and communication module.Industrial control host is the carrier of fire on-line monitoring main website, signal acquisition module is responsible for the monitor signal that reception monitoring terminal transmits back, industrial computer realizes fire alarm, fire point is located, terminal fault alarm, man-machine interaction, the functions such as communication interface, communication module is responsible for fire alarm signal and terminal fault signal to transfer to concentrator station through transformer station's telemechanical apparatus or intelligent substation backup system, realizes cable duct of substation fire and cable duct of substation fire on-Line Monitor Device operation conditions remote online monitoring.
The utility model beneficial effect is compared with the prior art, the utility model have employed Internet of Things ad hoc network, avoid in transformer station the work of laying the communication lines such as 485 or optical fiber, the monitoring terminal simultaneously newly increased can independently networking, avoid communication debugging efforts, monitoring terminal band self-checking function, can timed sending heartbeat message, guarantees that terminal is in normal operating conditions.
The utility model is applicable to the cable duct fire on-line monitoring of unattended operation transformer station.
Accompanying drawing explanation
Fig. 1 is a kind of cable duct of substation fire of the utility model on-Line Monitor Device structural representation;
To be that the process of traditional cable duct of substation fire is consuming time send the average contrast schematic diagram consuming time of grid company process after alarm signal with the utility model device to Fig. 2.
In figure, A1 is classic method discovery time; B1 is on-line monitoring method discovery time; A2 is that classic method is reached the spot the time; B2 is that on-line monitoring method is reached the spot the time; A3 is classic method repairing release time; B3 is on-line monitoring method repairing release time.
Embodiment
The utility model specific embodiment cable duct of substation fire on-Line Monitor Device as shown in Figure 1.Monitoring terminal in the present embodiment device is made up of temperature sensor, smoke transducer, microprocessor, power module, communication module.
Temperature sensor and smoke transducer are arranged in cable duct, determine according to actual needs to install quantity and concrete installation site, can Real-Time Monitoring present position environment; The signal of microcontroller acquires sensor collection is gone forward side by side row relax, and communication module adopts Internet of Things self-organized network communication mode, and signal microprocessor processes can crossed and terminal heartbeat message are sent to cable duct fire on-line monitoring main website.Power module provides power supply for monitoring terminal, adopts CT power taking to add lithium battery mode, under normal circumstances by being buckled in the CT power taking on power cable, if power cable stoppage in transit maintenance situation is by lithium battery maintenance work.
The main website of the present embodiment device comprises industrial control host, signal acquisition module and communication module, industrial control host is analyzed the cable duct of substation running environment monitoring information that monitoring terminal is beamed back in real time, find certain terminal send a message back exceed main website preset alarm threshold after, the breaking out of fire of main station judging cable duct also determines that position occurs fire, afterwards by the breaking out of fire of cable duct of substation position with the message format preset by telecontrol system being delivered to transformer station's concentrator station, notify after concentrator station operation monitoring personnel receive alarm signal that power transformation repair personnel goes to scene to carry out fire process.
