Be used to monitor the long distance wireless transmission system of electric precipitator dutyTechnical field
The utility model relates to the wireless supervisory control system technical field, especially a kind of long distance wireless transmission system that is used to monitor the electric precipitator duty.
Background technology
At present, the operation conditions of electric precipitator is machine room to be set by the artificial monitoring of finishing electric precipitator on duty by the scene mostly, this monitor mode, when the control point needs to drop into more manpower more for a long time, in addition when electric precipitator goes wrong the duty personnel at scene can not be immediately exactly information feedback to supplier personnel after sale, usually cause some problems not handled timely and magnify.
Along with networks development, many on-the-spot machine rooms press for by network the operation conditions of electric precipitator are carried out remote monitoring.
The utility model content
The technical problems to be solved in the utility model provides a kind of long distance wireless transmission system that is used to monitor the electric precipitator duty, and it can realize remote wireless monitoring to electric precipitator, in time handles some problems of electric precipitator emerged in operation, reduces cost of labor.
For achieving the above object, the technical solution of the utility model is: a kind of long distance wireless transmission system that is used to monitor the electric precipitator duty, comprise the PLC controller, terminal is gathered wireless transceiver, remotely controlling computer, long-range wireless transceiver, the PLC controller is gathered wireless transceiver with terminal and is connected, remotely controlling computer is connected with long-range wireless transceiver, the high-voltage board of PLC controller and electric precipitator, control rapping interface board and test point sensor are connected, video collector is gathered wireless transceiver with terminal and is connected, and terminal is gathered wireless transceiver and long-range wireless transceiver interrelates by GPRS or 3G wireless network.
The above-mentioned long distance wireless transmission system that is used to monitor the electric precipitator duty, described PLC controller also connects a personal-machine interface such as a touch-screen.
The above-mentioned long distance wireless transmission system that is used to monitor the electric precipitator duty, described PLC controller is gathered wireless transceiver with terminal and can be connected by R232 or RS485 bus, and described remotely controlling computer also is connected by R232 or RS485 bus with long-range wireless transceiver.
The above-mentioned long distance wireless transmission system that is used to monitor the electric precipitator duty, the optional industrial camera of using of described video collector.
The above-mentioned long distance wireless transmission system that is used to monitor the electric precipitator duty, described terminal are gathered wireless transceiver and are also connected a GPS.
The utility model is owing to utilize GPRS or 3G wireless network to carry out the transmitted in both directions of data, therefore monitoring is not subjected to the restriction of distance can realize remote wireless monitoring, again because the high-voltage board of PLC controller and electric precipitator, control rapping interface board and test point sensor are connected, just can be implemented in and show the high-voltage board running status on the display screen of remotely controlling computer, the working condition of vibration body and test point temperature, pressure and other parameters, can see electric precipitator work on the spot situation by video collector again, the personnel of Long-distance Control just can accurately judge some problems that electric precipitator occurs like this, in time send the problem that the instruction process electric precipitator occurs, the cost of labor that the personnel after sale of saving run back and forth, simultaneously also can realize monitoring the effect of a plurality of electric precipitator operation conditionss, further save the human cost that each point all will drop into the duty personnel by a control center.
When terminal is gathered GPS of wireless transceiver connection, also can carry out satnav to electric precipitator.

Embodiment
Below in conjunction with accompanying drawing and concrete embodiment the utility model is described in further detail.
Shown in Figure 1, a kind of long distance wireless transmission system that is used to monitor the electric precipitator duty, comprise PLC controller 1, terminal is gathered wireless transceiver 2, remotely controlling computer 3, long-range wireless transceiver 4, PLC controller 1 is gathered wireless transceiver 2 with terminal and is connected, remotely controlling computer 3 is connected with long-range wireless transceiver 4, the high-voltage board 6 of PLC controller 1 and electric precipitator, control rapping interface board 7 and test point sensor 8 are connected, video collector 9 is gathered wireless transceiver 2 with terminal and is connected, and terminal is gathered wireless transceiver 2 and long-range wireless transceiver 4 interrelates by GPRS or 3G wireless network 5.
PLC controller 1 connects a personal-machine interface 11.
PLC controller 1 is gathered wireless transceiver 2 with terminal and is connected by R232 or RS485 bus, and remotely controlling computer 3 also is connected by R232 or RS485 bus with long-range wireless transceiver 4.
The video collector 9 optional industrial cameras of using.
Terminal is gathered wireless transceiver 2 and is also connected a GPS 10.
The utility model can be achieved as follows function;
1, can realize transmitted in both directions, control center also can send the operational factor that electric precipitator is adjusted in instruction, as the high lower bound of cycle of cycle of operation of setting or revising motor and working time, vibrator and height, heter temperature etc.
2, when the PLC controller is connected with man-machine interface such as touch-screen, the display screen 31 of remotely controlling computer 3 can show the content of parameter same with man-machine interface 11, so that the operation conditions of monitoring electric precipitator;
3, can inquire about the history data of electric precipitator, but also current warning and historical alarm condition in the observing system;
4, follow the tracks of the safe operation of realization system by IP filtering technique, identification authorization and cipher authentication system, data security encrypted tunnel and access process;
5, can realize video monitoring,, allow all relevant staff, as long as just can any control point of real time remote video monitor field condition by computer and internet no matter in where by video collector real time remote video monitoring;
6, each monitoring station can be set to self-timing and send information to control center, also can be set to be at ordinary times holding state, just begins startup work after the instruction of receiving control center, and information is sent to control center.
7, when terminal is gathered GPS of wireless transceiver connection, also can carry out satnav to electric precipitator.
