Embodiment 1

[0016] Embodiment 1: An unattended remote control distributed sewage treatment control system is composed as follows:

[0017] 1) see figure 1 , a 2000 tons / day village and town sewage treatment plant, the control system of the entire sewage treatment plant is equipped with a main controller 1 and five identical sub-controllers 2 . ( figure 1 Only three sub-controllers are shown in 2). The main controller 1 and each sub-controller 2 are embedded systems. Embedded systems include embedded system chips, input circuits and output circuits. The main controller and each sub-controller are arranged in the same control cabinet and connected by industrial bus. 2) see figure 1 , set the network remote control system 3 connected with the main controller 1, including: a communication module 3 connected in sequence 1 , Router 3 2 , Internet 3 3 , a remote networked server 3 4 , Remote Internet-connected mobile phone 3 5 and a remote networked computer3 6 . Remote Internet Serv...

Embodiment 2

[0020] Embodiment 2: This embodiment 2 is except the following characteristics, and it is identical with embodiment 1: see figure 2 , Figure 4 , the main process equipment 2B used by the sub-executive agency is: a water pump 2B is installed on the main water inlet pipe 6 1 A solenoid valve 2B is installed on each inlet branch pipe 7 connected with each sewage treatment unit 5 2 . When sewage is pumped by pump 2B 1 Send it into the water distribution main pipe 6 and then flow into each water distribution branch pipe 7, and automatically control the solenoid valve 2B through the sub-controller 2 2 , and then control the flow of sewage entering each sewage treatment unit 5 . Multi-channel solenoid valve switches are generally used in occasions where the diameter of the water outlet is Ф≤100mm.

Abstract

The invention discloses an unattended remote-control distributing sewage treatment control system. The unattended remote-control distributing sewage treatment control system comprises one master controller on auxiliary control process equipment and more than one sub distribution controllers on master control process equipment, the master controller and the sub distribution controllers all adopt embedded systems or industrial personal computer controlling cards. The unattended remote-control distributing sewage treatment control system is further provided with a network remote-control system and a networking server, wherein the network remote-control system can be communicated with a remote-terminal cellphone or a computer, and the networking server contains sewage treatment states and a parameter database. The master process equipment includes a water pump and a controllable water distributor or a water pump and multiple electromagnetic valves. The controllers are mutually standby, so that the unattended remote-control distributing sewage treatment control system cannot be totally stopped by a fault of one of the controllers, no special standby article waste is caused, and water positioning, water quantifying and timing control are realized by the controllable water distributors. A manager can remotely control and treat accidents during sewage treatment in real time via the cellphone or the computer. A water quality sensor can be allocated according to needs, treating technological parameters are optimized, and year-round duties of technicist are avoided. The unattended remote-control distributing sewage treatment control system realizes sewage treatment plant without technicist, and is applicable to plants with daily treatment volumes more than 100 tons.

Description

[0001] (1) Technical field: The present invention is an automatic control system in a sewage treatment system, mainly related to the automatic configuration, adjustment, maintenance and remote control of sewage parameters and water distribution status. It belongs to sewage treatment category (C02F), water distribution or water distribution device category (E03B), control regulation category (G05B), communication information transmission category (H04L). (2) Background technology: [0002] In the existing sewage treatment system, the control methods of sewage water quality and treatment process parameters are mostly carried out manually: for example: ① sewage chemical oxygen demand COD value, sewage pH value and other sewage parameter values ​​are manually sampled, manually analyzed and calculated, and then press Calculate and analyze the results and manually adjust the process parameters. ②The ventilation volume of the blower is also often manually fine-tuned. These manual me...
