Controller used in spiral-flow desilting technology

Abstract

The invention relates to a controller used in a spiral-flow desilting technology. The controller comprises a master control chip, of which a signal input end is connected with an output end of a signal input circuit, a signal output end is connected with an input end of a relay output circuit and a communication end is connected with a communication module. For the controller, the master control chip is used, the spiral-flow desilting technology rules are embedded in the master controller, and users are free from programming, so that integration and construction cost of an automatic control system is saved, and decentralized control on a sewage treatment process is realized; and simultaneously, the controller is in communication with a control management center through the communication module, so that the distributed control requirement on the sewage treatment process is satisfied, and centralized management on the sewage treatment process can be realized. The controller can be matched with the spiral-flow desilting mechanical equipment to form the mechanical-electrical integrated novel spiral-flow desilting technology equipment, so as to promote the technical progress of mechanical products and improve the additional value of the mechanical products.

Description

[0001] technical field [0002] The invention relates to the field of swirling sand sedimentation technology, in particular to a controller used in the swirl sand sedimentation technology. [0003] Background technique [0004] At present, most of the control tasks of the sedimentation process unit in the primary sewage treatment process are incorporated into the centralized control unit of the primary treatment process. This control method has the following two defects: First, due to the different sedimentation processes, based on The control system realized by programmable logic controller PLC, in terms of system software and hardware design, requires a system integration engineer who is familiar with the swirling sand sedimentation process and special equipment for sand sedimentation before he can design or modify the system; , during the joint debugging of the primary process control system of sewage treatment, since the control programs of each sub-process unit are com...

[0004] At present, most of the control tasks of the sedimentation process unit in the primary sewage treatment process are incorporated into the centralized control unit of the primary treatment process. This control method has the following two defects: First, due to the different sedimentation processes, based on The control system implemented by the programmable logic controller PLC, in terms of system software and hardware design, requires a system integration engineer who is familiar with the swirling sand sedimentation process and the special equipment for sand sedimentation before he can design or modify the system; , during the joint debugging of the primary process control system of sewage treatment, since the control programs of each sub-process unit are combined into one task, in fact, a centralized control is realized, which brings a lot of inconvenience to on-site debugging and program modification. This will increase the cost of construction and commissioning, and also reduce the reliability of system operation.
