Abstract
The utility model provides the technical scheme of a PLC (programmable logic controller)-based sewage treatment device. The sewage treatment device of the scheme comprises an industrial control computer that is provided with a display and connected with a PLC control cabinet controlling power equipment; the industrial control computer is connected with a secondary instrument cabinet that is connected with a plurality of sensors; in addition, a UPS (uninterrupted power supply) is further connected with the industrial control computer. The device of the scheme realizes the centralized management and control of the computer, running situations of all devices and various on-site datum can be displayed by the computer, the control is more accurate and the operation is more convenient.
Description
Technical field
The utility model relates to a kind of sewage disposal device, especially a kind of sewage-treatment plant based on PLC.
Background technology
At present entire sewage being handled project generally all is manual control, artificial monitoring, this situation has increased lot of manpower and material resources to a certain extent, increased the operating cost of enterprise greatly, and be not easy to manage, and the control out of true often causes water quality not up to standard because of artificial some carelessness, does not satisfy production.This is the existing in prior technology weak point.
Summary of the invention
The purpose of this utility model, be exactly at the existing in prior technology deficiency, and provide a kind of technical scheme of the sewage-treatment plant based on PLC, the device of this scheme has been realized the centralized management and the control of computing machine, the various data at all devices and ruuning situation and scene can present on computers, and control more accurately, it is convenient to operate.
This programme is realized by following technical measures: a kind of sewage-treatment plant based on PLC, comprise the industrial computer that has display, described industrial computer is connected with the PLC switch board of control power-equipment, described industrial computer is connected with the secondary instrument cabinet, described secondary instrument cabinet is connected with a plurality of sensors, in addition, also have a UPS uninterrupted power source to be connected with described industrial computer.Described industrial computer is connected with the secondary instrument cabinet with the PLC switch board respectively by the RS485 port.
The beneficial effect of this programme can be learnt according to the narration to such scheme, because in this scheme, industrial computer is arranged, can implement to monitor long-time running, and can with PLC switch board and the telecommunication of secondary instrument cabinet, display can show relevant information timely, and configuration software is arranged on industrial computer, configuration software is selected power control 6.1, power control configuration software integrates control technology, real-time data base technology, network technology, human machine interface technologies, graph technology, comprises assemblies such as dynamic demonstration, warning, control, trend, network communication; The secondary instrument cabinet, concentrate and real time data that on-the-spot each sensor of reaction accurately will detect as flow, temperature, pH value, pressure etc., and detected data in time are reflected to industrial computer; The PLC control is used for the startup of power-equipment and the control that stops; In addition, also have a UPS uninterrupted power source to be connected, when running into emergency condition such as power failure, can power, avoid losing of data to industrial computer with industrial computer.This shows that the utility model compared with prior art has substantive distinguishing features and progress, the beneficial effect of its enforcement also is conspicuous.
