Embodiment 1

[0019] The remote monitoring system of the sewage treatment process of the present invention includes field equipment and management equipment, and the two perform data exchange through the field bus, wherein the field equipment includes field instruments, execution components, PLC and industrial switches, and the field instruments send the collected field data to the PLC , the PLC then outputs the control signal to the execution unit, and at the same time, the PLC acts as an OPC server to exchange data with the industrial computer and the server in the management equipment through the field bus through the industrial switch; the management equipment includes the industrial computer, the switch, the server, the management computer and the enterprise WEB server , where the management machine communicates with the server through the switch, and the server serves as the OPC client to publish the data to the enterprise WEB server, and the superior department will uniformly plan the ...

Embodiment 2

[0034] In order to improve the automation level of the enterprise and respond to the requirements of the environmental protection department for real-time network monitoring, a domestic sewage treatment plant in Guangzhou implemented this remote monitoring technology for sewage treatment.

[0035] The automatic control method is PLC program control, using Siemens PLC300 series CPU315-2DP and data acquisition module. Automatic control can realize sequential control, logic control, linkage and chain, as well as signal transmission, alarm and data acquisition. A Profibus-DP communication module CP is installed on the PLC rack to connect with the Profibus-DP field bus. As the slave station of Profibus-DP field bus, PLC communicates with the host computer through the bus. The PLC with Profibus-DP network communication interface can be used as the master station of Profibus-DP field bus, connected with the remote distributed intelligent I / O module of the control field, and realizes...

Abstract

The invention relates to a remote monitoring system of a sewage disposal process and an implementation method thereof. The method comprises the steps: collecting real-time monitoring data and writing into a database of an enterprise WEB server database; issuing the real-time data by the enterprise WEB server through a standard http protocol; mapping the data into Internet server, directly obtaining the data from a browser when a customer browses the Web server, wherein the monitoring system comprises a field apparatus and a management device; transmitting the collected field data to a PLC (programmable logic controller) to control an execution component by a field instrument in the field apparatus; simultaneously carrying out data interaction on an industrial personal computer and a server by the PLC via an industrial switch; carrying out communication connection with the server through the switch by the industrial control computer in the management device; and issuing the data to the enterprise WEB server by the server as an OPC (OLE for process control) client. According to the remote monitoring system disclosed by the invention, an operator can achieve constantly grasping of production and operation in everywhere and the mode that a set of technical service personnel is configured for each sewage treatment plant in the past is avoided, so that manpower resource is greatly saved and the operation cost is reduced.

Description

technical field [0001] The invention relates to a monitoring technology in the process of sewage treatment, in particular to a remote monitoring system for the process of sewage treatment and its realization method. Background technique [0002] With the enhancement of people's awareness of environmental protection, the domestic sewage treatment industry has developed rapidly in recent years, and it is in line with international standards in terms of construction scale and equipment level. However, my country's sewage treatment enterprises generally have a low degree of informatization, lack of technical personnel, and low management levels. It directly leads to the disconnection between the management and the production layer, and the production problems cannot be dealt with in a timely manner. At the same time, due to poor information, it is impossible to be unattended on site, and the labor cost is too high. [0003] Domestic sewage treatment plants are generally equipped ...
