Technical field
The present invention relates to the tele-control system in the industrial control field, relate in particular to a kind of power plant environment pollution harnessing remote diagnostic control system.
Background technology
Along with fast development of national economy, no matter being industrial enterprise or resident living grows to even greater heights to the demand of electric power, and electric power facility is constantly built, and wherein the fuel-burning power plant still occupies main flow.And the fuel-burning power plant defective of self especially, that is exactly a large amount of flue dust and a harmful gas of discharging.In the face of the current environment that goes from bad to worse, country makes a decision and administers or close down the enterprise of high pollution, wherein explicitly calls for the fuel-burning power plant must possess desulfuring and denitrifying apparatus and just can generate electricity by way of merging two or more grid systems.
The pollutant that thermal power plant is eliminated in institute's discharging waste gas mainly uses desulfuring and denitrifying apparatus, the DCS control system of existing desulfuring and denitrifying apparatus is mainly monitored our factory desulphurization denitration engineering process system, finish analog quantity control (MCS), sequential control (SCS), data acquisition (DAS) and the accident sequence system (SOE) of regulation, to satisfy the requirement of various operating conditions, guarantee safety, efficient operation.And the data of desulphurization denitration engineering DCS are delivered to the existing plant level supervisory information system of power plant (SIS) by redundant interface.
Yet, in order to guarantee the profit of generating plant, some generating plant take to start desulfuring and denitrifying apparatus and not the means of actual motion escape environmental administration supervision, discharge a large amount of harmful gases and flue dust privately, the idle fragile now environment of fund waste order too that causes of the environmental protection equipment that the appearance of this phenomenon had both made country's cost substantial contribution start makes the matter worse.
Summary of the invention
Purpose of the present invention just is by the DCS data of each power plant desulfurization denitrification apparatus are sent to a remote centralized control system, monitor and diagnose the operation conditions of desulfuring and denitrifying apparatus by long-range expert's Centralized Monitoring mode, can either sufficiently and reasonably use Expert Resources like this, in time each power plant's operation data is analyzed, is diagnosed and provide the method scheme that solves abnormal conditions, can save power plant's environment protection treating facility again and run the input of on-the-spot professional, expert's number, also help the operation that environmental administration supervises the desulphurization denitration environmental protection equipment more easily.
To achieve these goals, the invention provides a kind of power plant environment pollution harnessing remote diagnostic control system, this system comprises some factories end watch-dog and is used for the remote monitoring center of each described factory end watch-dog work of monitoring management, described each factory's end watch-dog comprises that the information that connects factory's end internal network reads storage facilities, and described each factory's end watch-dog establishes a communications link by public wired or wireless communication network and described remote monitoring center.
Wherein, described factory end watch-dog also comprises fire wall, and its information of being arranged at reads between storage facilities and the described public wired or wireless communication network, is subjected to the invasion of external network in order to prevent factory's end internal network.
Wherein, described public cable network comprises that public network ADSL inserts, and stable data transmits in order to satisfy more, also can use DDN private line access described factory end watch-dog and remote monitoring center.
Wherein, described public wireless communication network comprises that GPRS inserts, promptly load the device that the GPRS modulator-demodular unit sends and receives as data respectively at described factory end watch-dog and described remote monitoring center, data transmit in order to satisfy faster, also can use the CDMA1X technology as data transfer means.
Wherein, to read storage facilities be to utilize general-purpose interface to connect the multi-purpose computer of factory's end internal network to described information.
Wherein, described general-purpose interface is an Ethernet interface, and described information reads storage facilities can insert factory's end internal network and plant level supervisory information system (SIS) communication by netting twine and switch.
Wherein, described remote monitoring center is reliable high-performance computer, and is provided with some giant-screens, and the corresponding factory of each giant-screen end watch-dog is for the directly perceived real-time information that each factory's end watch-dog transmits of checking.
The invention provides a kind of power plant environment pollution harnessing remote diagnostic control system, it mainly utilizes the watch-dog that quarters at each factory's end to read the DCS data of power plant desulfurization denitrating system, and send to long-range Surveillance center by public wired or wireless network, the data of coming for the unified analysis of the expert of Surveillance center transmits, this diagnostic control system helps the supervisory control system running state, unusual circumstance in time, and saved the professional greatly, expert's human input, also can avoid desulphurization denitration equipment that the generation of the circumstances that construction do not move is arranged, be beneficial to the supervision of environmental administration.
Description of drawings
Fig. 1 is the structural representation of one embodiment of the invention
Embodiment
Now according to accompanying drawing, the present invention will be further described.
Please refer to shown in Figure 1, power plant environment pollution harnessing remote diagnostic control system comprises remote monitoring center 10, fire wall 30, interface computer 40 and the public internet 20 that connects remote computer and fire wall, fire wall 30 is by network connection interface computing machine 40, and interface computer 40 is by network insertion power plant internal network 50.
Wherein remote control room 60 is the machine rooms away from power plant and built-in remote monitoring center 10.Pulpit 70, electric room 80, on-the-spot 90 all are positioned at power plant inside.Wherein 70 inside, pulpit have power plant's internal network 50, and are connected SIS system, operator station 100, interface computer 40, fire wall 30, engineer station, long-range FGD-DCS active station on power plant's internal network.Electric room 80 built-in DCS racks 110, DCS rack 110 stands 100 and the engineer station by network attended operation person.On-the-spot 90 comprise remote cabinet 120, and remote cabinet 120 connects unit 110 by network.
