Abstract
Disclosed is a power station ventilation control system, comprising fire hazard signal sensors and ventilation monitors which are arranged at the workshops of the power station, wherein the sensors and the monitors are connected with a PLC; the PLC is respectively connected with blower fans and fireproof valves arranged in the workshops of the power station via a soft starter; and the PLC controls the motions of the blower fans and fireproof valves according to the signals transmitted by the sensors and the monitors. The power station ventilation control system of the utility model adopts the PLC to automatically control the start/stop of the blower fans and the open/close of the fireproof valves. When a fire hazard happens, the PLC, after receiving the fire hazard signals, automatically stops the blower fans and turns off the fireproof valves, thereby realizing the objectives of unmanned on duty and automatic control and reducing the number of the working personnel. In addition, the remote control can be realized via network.
Description
Technical field
The utility model relates to the ventilating system in power station.
Background technology
At present, the Ventilation Control scheme implementation of each factory building of power station only has manual Starting mode, and when needs were opened blower fan, the power station staff was on-the-spot to blower fan, artificially starts blower fan and opens electric fire-damper; When on-the-spot breaking out of fire, the staff need arrive the scene and stop blower fan and close electric fire-damper.This mode not only automaticity is low, need operating personnel according to operating process step by step manual operation the corresponding button operate; And elapsed time is many, inefficiency.
The utility model content
For above-mentioned technical matters, but the utility model provides a kind of unmanned, ventilation automatic control system simple to operate.
The technical scheme in the invention for solving the above technical problem is: the power station ventilated control system, comprise the fire signal sensor and the ventilation watch-dog that are arranged on each factory building of power station, described sensor is connected with a PLC controller with watch-dog, this PLC controller is connected with fire resisting damper with the blower fan that is arranged on Power Plant respectively by soft initiator, and described PLC controller is according to sensor and the described blower fan of signal controlling of watch-dog transmission and the action of fire resisting damper.
Further, described PLC controller is connected with server by telecommunication network.
Further, described PLC controller connection is connected with a touch display screen.
As can be known from the above technical solutions, the utility model adopts the PLC controller automatically to control the start and stop of blower fan and the switching of fire resisting damper, when breaking out of fire, the PLC controller automatically stops blower fan and cuts out fire resisting damper after receiving fire signal, realize unmanned, automatic control function, less personnel's work; And can realize Long-distance Control by network.
Description of drawings
Fig. 1 is structured flowchart of the present utility model.
Embodiment
Below in conjunction with Fig. 1, the utility model is described in further detail:
This ventilated control system comprises fire signal sensor 2 and the ventilation watch-dog 3 that is arranged on each factory building 1 of power station, power station fire signal sensor and ventilation watch-dog generally are installed on Main Underground factory building, underground both ends auxiliary power house, bus tunnel, main transformer hole, tail lock chamber, outlet hole, ground and control the positions such as building and main air draft building, and blower fan 4 and fire resisting damper 5 etc. also are installed in it.Air-conditioner host, centrifugal blower, dehumidifier, axial flow blower, smoke exhaust fan, explosion-proof axial flow fan etc. are mainly monitored and controlled to the ventilation watch-dog, and detection signal is passed to PLC controller 6, the signal controlling soft initiator 7 that described PLC controller transmits according to sensor and watch-dog or the switching of contactor, thus the action of described blower fan and fire resisting damper controlled.When breaking out of fire, the PLC controller automatically stops blower fan and cuts out fire resisting damper after receiving fire signal; After fire is eliminated, can automatically open blower fan and fire resisting damper.
In implementation process, described PLC controller 6 is connected with server 8 by telecommunication network, and described PLC controller connection also is connected with touch display screen 9, can implement the display monitoring data.The PLC controller is with monitor data delivery network server, and the staff can carry out Long-distance Control according to actual conditions, and is need not personnel on duty, just can guarantee factory building safety, and it is not only simple to operate, and the workload that reduces a staff.
Above-mentioned embodiment is only for illustration of the utility model, and be not to be to restriction of the present utility model, the those of ordinary skill in relevant technologies field, in the situation that do not break away from the utility model spirit and scope, can also make various variations and modification, so all technical schemes that are equal to also should belong to category of the present utility model.
