Description
Patent of the present invention relates to a kind of computer network platform control system for environment-protecting garbage incinerating power plant.
Along with popularizing and development of computer, the development of automatic control technology, microprocessing, the network communications technology and develop computer software technology, ripe and interosculate has become the inexorable trend of large industrialized production automatic control technology.The combination of above four kinds of technology at present is comparative maturity, is widely used in the production process automatic control system of all trades and professions.With regard to the thermal power generation industry, the scattered control system of the communication Network Based of more than ten perfect in shape and function, technology maturation is released in the exploitation successively in recent years of many countries.But the centralized and automatic of existing refuse-burning plant control level is not high, is the manual operations that disperses mostly, does not realize the control of overall process, only by simple pure computation yet.
Manually discontinuous in order to change, the situation of scatter operation control, reach the control of from the refuse collection to the electric energy, exporting whole process, only need by the concentrated simple operations of computer (computer automation fully), the purpose of enhancing productivity, by continuous effort, the core that we have developed environment-protecting garbage incinerating power plant is computer network platform control system for environment-protecting garbage incinerating power plant one by one.
The present invention is based on computer network platform, carry out the overall process computer monitoring, finlling automatically, automatically igniting combustion supporting, automatically rise close, debugging automatically, precise and high efficiency, concentrated controling management.Output realizes full process automatization from the refuse collection to the electric energy, avoids the manually-operated that each system disperses and influences each other, and realizes the garbage power automation on the complete meaning.
Be further detailed below in conjunction with accompanying drawing:
Fig. 1 is an environment-friendly garbage garbage incinerating power plant computer network platform control system structure chart;
Fig. 2, Fig. 3 are respectively the software system function module map;
Fig. 4 is hot fuel gas generation entire system system diagram.
The environment-protecting garbage incinerating power plant whole system comprises following five subsystems: automatic garbage-collecting sifting sort system, automatic dehydration chopping system, gasification system, residue are cleared up system, fuel gas generation system automatically.After refuse collection, through letter sorting automatically, strict separately combustible and noncombustibles, noncombustibles directly enters waste and old material collection centre, combustible send the dehydration drum to carry out drying, advances the cutter drum chopping then, puts into storage drum again, suitably add other combustion-supporting material according to the actual conditions of combustible, hybrid process factory becomes set solid refuse combustion (RDF), RDF is sent hot gas combustion apparatus high-temp combustion again, produces fuel gas, a small amount of residue of supervening is discharged by rotation cleaning tube, fuel gas then send the heat energy oxidation unit, and the fully burning under oxygen condition in abundance produces a large amount of heat energy, boiler is subjected to heat energy to produce steam, the pushing turbine generating.
Reach the control of from the refuse collection to the electric energy, exporting whole process, only need purpose, must resolve following technical problem by the complete computer important task automation of the concentrated simple operations of computer.
1, the automatic control of each subsystem inside of environment-protecting garbage incinerating power plant, whole control and MICROCOMPUTER PROCESSING technical problem automatically.
2, the automatic control of environment-protecting garbage incinerating power plant whole system and microprocessing problem.
3, whole system networking problem.
4, the communication interface problem of each subsystem and network.
5, whole computer network platform software reasonable development problem.
For above-mentioned technical problem 1 and technical problem 2, the front is mentioned, and many countries have provided the solution of comparative maturity, as see the INFI of sharp Heat ﹠ Control Pty Ltd.---90 systems, the I/A system of Fox's POLO company, the MAX1000 system of Li Nuo company, the WDPF system of Westinghouse Electrical Corp..
For technical problem 3, i.e. whole system networking problem, native system is set up the fiber data highway, adopts ring topology.Have six nodes to be respectively on the topological structure center ring: refuse collection letter sorting screening system, the broken system of dewatering, gasification system, residue cleaning system, combustion, gas electricity generation system, engineer work station, and have an operation-interface station to be connected on the center ring.The engineer work station is in the highest the driver's seat of whole system.The system of all the other five nodes itself is again a ring type structure except that the engineer work station.Refuse collection letter sorting screening system is made up of collector unit, letter sorting screening unit, multifunctional processor, computer interface unit; Dehydration chopping system is made up of dewatering unit, chopping process control unit, operation-interface station; The gasification system is made up of storage element, mixed cell, hot gasification unit, computer interface unit, multifunctional processor; Residue cleaning system is made up of cleaning unit and operation-interface station; The fuel gas generation system is made up of boiler unit, heat energy oxidation unit, steam turbine unit, variable power transmission unit, multifunctional processor, computer interface unit.By computer interface unit control multifunctional processor, thus the running of control sophisticated subsystems, and simple subsystem can be controlled by the operation-interface station.The annular optical fiber data highway has anti-electromagnetic interference, anti-Radio frequency interference, anti-all telecommunications interference, anti lightning, corrosion-resistant, humidity and does not have advantage such as earth-return circuit, and high reliability is arranged.Adopt the token passing formula, have good response speed, can satisfy the distributed real-time control requirement of system.
For technical problem 4, it is the communication interface problem of each subsystem and network, the fiber data highway of native system is ring-like token passing bus, it uses and is similar to RS485 shift keying (FSK) signal of (or claiming EIA485), High-Level Data Link Control (HDLC) form is followed the DEEE802.4 standard.
For technical problem 5, it is the reasonable development problem of whole computer network platform software, native system is intended developing at open multi-user operating system unix platform, employing is based on the WEB Content Management, the tool database software INFORMIX of document library function, the front end developing instrument can use the visual programming tools POWERBUILDER with powerful database support function.Realize following function by the software that above scheme is set up:
1, exploitation and realization control strategy;
2, develop and manage system database;
