【正文】 s name and password and then can carry out long range came to carried on a control to the equipments of whole the sewage data of wastewater treatment factory to the national environmental protection bureau through an Inter in the meantime city environmental protection bureau perhaps, for the purpose of the Bu class management of section to wastewater treatment factory. 。s interface, and have online follow and offline imitate true control procedure of PLC3 stationses is divided into five procedure mold piece. (1)Public mold pieces of procedure useinclude a beginning to start to turn part, hour cent second etc. ask pulse unit, SBR to respond a period enactment, fuse oxygen enactment...etc.. (2)Order control mold pieces of the switch quantity the coordination control report to the police of circulate and related breakdown of equipmentses, such as each valve, pump and breeze machine...etc.. The enter of SBR pond spirit valve, enter water valve, reflux pump, surplus dirty mire pump from PLC according to the craft of the wastewater treatment period time segment control, water valve from PLC according to craft time and super voice liquid the measured value of the instrument to control. (3)Protection mold pieces of the offpowersystem power failure after, the PLC saves all appearance locks and make after treating to add an electricity PLC instauration keep of the appearance continue to circulate. (4)Mold pieces of correspondences use to plete PLC and various data transmission of place of honor machine. (5)Fuse an oxygen value to automatically regulate a mold pieceaccording to fuse an oxygen value to regulate breeze machine to turn soon and report to the police of related target which regulates to turn soon promises the be worth of deliquescence oxygen as 2 mgs/L in the whole Pu spirit control strategy is as follows:The Pu spirit period beginning, the breeze machine at top speed movement attains a 2 mgs/L in shorterly of the hour ask by making deliquescence oxygen and take 5 mins as a period to examine deliquescence oxygen to be worth in the fuse an oxygen value big at the 2 mgs/L, the breeze machine turns to soon descend 5%。t need to operate a personnel an spot data spreads a highest machine through a PLC, e out in the place of honor on board description and make the craft, equipments movement of whole factorieses get an overall control. The living creature processing part of the PLC3 station control is the whole wastewater treatment of key part, be limited by space, only with the PLC3 stand of program design for example. Process of control The PLC3 stationses were use to control to get into Pu spirit from sewage, the pond is everywhere sewage run off Pu after manage spirit the whole process of the turn of sequence and time switch moderate breezes machine of control various valve, pump, breeze machine to soon regulate etc. in this Pu spirit pond is the core of wastewater treatment to construct a thing, sewage is to e and go through a microbial living creature oxygenation in the pond in addition to anic matter, the processing effect of content to sewage of the oxygen in water is to go to a pass according to the SBR craft, the deliquescence oxygen in the Pu spirit pond content usually controls within the scope of 1~3 mgs/L and annoy a stage end to fuse an oxygen content in the Pu should be not over the 2 mgs/ the oxygen once measured low or lead Gao, all will influence a fluid matter 4 sets of the 10 104 t the SBR of 8 pond modes to respond pond to the day, each one responds that the pond go together with a pedestal from change Pin machine control of breeze machine, used for annoying pond Pu spirit to by turn provide oxygen toward two 4 pieces of deliquescence oxygen test instruments in the different location of each Pu spirit pond, measure contain of sewage amount of oxygen in pond, the PLC separates a 5 mins to examine a deliquescence oxygen in a Pu spirit pond value each time, acc
