Description
Technical field
The present invention relates to the monitoring technique in a kind of sewage disposal process, a kind of specifically sewage disposal process long distance control system and its implementation.
Background technology
The enhancing of Along with people's environmental consciousness, domestic in recent years sewage treatment industry development is swift and violent, and is all in line with international standards from the construction scale to the equipment level; But the general level of informatization of wastewater treatment in China enterprise is not high, the technician lacks, management level are low, directly causes administration and supervision authorities and productive zone to disconnect, and the production problem can not get timely processing; Simultaneously; Because information is not smooth, can't accomplish on-the-spot unmanned, human cost is too high.
Domestic sewage treatment plant generally all can be equipped with the Automatic monitoring systems of level of factory; But large-size enterprise group for the how tame wastewater treatment of operation enterprise; The managerial personnel of specialty, technology and control expert can't come to the scene of each subsidiary factory personally; Lean on the inner opaque management of each subsidiary factory can't grasp the situation of sewage treatment plant's production and operation at any time, production and operation situation can't be combined closely with the business games of enterprise.
Sewage treatment plant often is the more remote place, suburb of establishing the city, and often with noise, stink, the technology and the control technology personnel of specialty can not quarter at the production scene in real time in the production run; Can not do sth. in advance to judge, in time solve for the problem that possibly occur in producing; Industrial accident takes place frequently also just not at all surprising, therefore, is badly in need of a kind of long distance control system that is applicable to wastewater treatment enterprise; The Information Network of enterprises is coupled together with the control net effectively; Realize that the real-time collection of on-the-spot service data is concentrated with fast, obtain the on-site supervision data, for the remote fault diagnosis technology provides foundation.Simultaneously; Through remote monitoring, the technical specialist need not be in the action or rugged environment just can be kept watch on and the running status and the various parameter of control and field apparatus, utilizes local abundant software and hardware resources that remote object is carried out level process control easily; Normal operation with service equipment; Thereby reduce staff on duty, finally realize the unmanned or few man on duty of far-end, reach the purpose of personnel reduction and enlargement.And the sewage disposal process long distance control system that can realize above-mentioned functions is not at present appeared in the newspapers as yet.
Summary of the invention
The situation that can't grasp sewage treatment plant's production and operation at any time that exists to sewage disposal process in the prior art, production and operation situation are with the business games of enterprise above-mentioned weak point such as can't combine closely; The technical matters that the present invention will solve provides and a kind ofly can reduce sewage treatment plant particularly maintenance, management and the operation cost of some groups of large-scale enviromental protection enterprise, improves sewage disposal process long distance control system and its implementation of its management level.
For solving the problems of the technologies described above, the technical scheme that the present invention adopts is:
Sewage disposal process remote monitoring implementation method of the present invention may further comprise the steps: by field apparatus at the real-time monitor data of sewage treatment plant's collection in worksite; Server reads the real-time monitor data of opc server as the OPC client; Server writes the WEB of enterprise server database through the SOCKET service agreement with real-time monitor data; The WEB of enterprise server passes through standard http protocol issuance real time data, and is mapped as the Internet server, makes real-time running data to be visited through Internet; Long-range, when the monitoring client browses Web server, directly in browser, obtain data through the Http agreement.
Said server writes the WEB of enterprise server database through the SOCKET service agreement with real-time monitor data: writing on the server that can surf the Net with the application program on the Socket exploitation TCP/IP network; And its IP address is configured, make the resource of the WEB of enterprise server through the fixed ip address access server.
The said WEB of enterprise server need be put in order the data based enterprise of each sewage treatment plant to be incorporated on the OPC client end interface and show; The said WEB of enterprise server is chosen each sewage treatment plant data that need, that can externally announce and is put in order, screens, and on the OPC client end interface, shows.
Sewage disposal process long distance control system of the present invention comprises: field apparatus and management equipment; The two carries out exchanges data through fieldbus; Wherein field apparatus comprises field instrument, execution unit, PLC and industrial switch; Field instrument is delivered to PLC with the field data that collects, and PLC outputs control signals to execution unit again, and PLC carries out data interaction through industrial switch through industrial computer in fieldbus and the management equipment and server as opc server simultaneously; Management equipment comprises industrial computer, switch, server and the WEB of enterprise server, and wherein industrial computer carries out communication through switch-to-server and connects, server as the OPC client with data issuing to the WEB of enterprise server.
To reflect the uniform data planning in the WEB of the enterprise server of the condition of production of each sewage treatment plant of subordinate by higher level department, be published to the internet.
Said field instrument comprises: online dissolved oxygen instrument, sludge concentration meter, instrument transmitter or sensor; Said execution unit comprises: blower fan, pump class, valve; Said management equipment also comprises supervisor, is 1 or many, links to each other through switch-to-server.
The present invention has following beneficial effect and advantage:
The present invention make the operator can realize anywhere to produce, the grasp constantly of operation situation, combine closely production and operation situation with the business games of enterprise, in case when own insurmountable problem has appearred in certain sewage treatment plant; The technical specialist can be through the monitor message of internet; Analyzing failure cause, the scheme that proposition is dealt with problems directly conveys to sewage treatment plant with solution; Fix a breakdown; Avoided the sort of each sewage treatment plant in the past all need dispose the mode of a cover service technician, practiced thrift human resources greatly, cut operating costs.
