Houshi Industrial Switch Solution for Water Supply Automation

Water supply automation technology is to realize the automatic monitoring of each water treatment equipment and the whole process of each production link, to achieve the degree of automation of "unattended on-site and few people on duty in the control center", enabling the entire water plant system to realize self-energy control technology.

The water supply automation system is composed of the upper software platform and the lower water supply control unit. Through the comprehensive use of each communication network, the network software platform can realize the important water supply units under the jurisdiction of the water company (intake pump station, water source well, water plant, pressurized pump station, water supply Pipe network, etc.) are included in all-round monitoring and management, so that the water supply dispatching center can remotely monitor the real-time production data and equipment operating parameters of each water supply unit, and remotely manage water supply equipment such as pumps and valves.The water supply automation system is mainly composed of remote monitoring system, remote monitoring system, remote meter reading system and other systems.

Remote monitoring system: The remote monitoring system includes monitoring the operating status and operating parameter information of remote pumping stations, remote water source wells, remote water plant storage tanks, and clear water tanks, as well as remotely starting and stopping pumps, valves and other equipment.

Remote monitoring system: The monitoring system realizes monitoring of important areas of the water plant to ensure production safety and incident detection.

Remote meter reading system: Remotely collect the total water consumption data of each area, and collect the water consumption information of each large water user.

The development process of Chinese water plant water supply automation system can be divided into three stages: the first stage is the decentralized control stage, during which each part of the water plant is automatically controlled, and the independent systems are not related; the second stage is the water plant synthesis. In the automation stage, the entire water plant is produced as an integrated automatic control system, and each independent subsystem can work independently. The system shares the information of the entire water plant and has the possibility of decentralized control. At this stage, most water plants are in this stage; the third stage is the comprehensive automatic control stage of the water supply system, which requires water supply companies in a region to share information to realize automatic control of the entire city or regional water supply system.Most of my country's small and medium-sized water plants are in the first or second stage, and only a few large water plants have reached the third stage.

This situation brings a lot of inconvenience to operation management, which is reflected in the following aspects:

1. The scattered distribution of the subordinate factories of the water plant, many production links require manual operation and maintenance;

2. Water plant automation equipment cannot be managed remotely, and routine maintenance and troubleshooting require on-site maintenance by professionals;

3. The sources of statistical data related to the operation data of water plants are different, resulting in a large number of statistical data, which not only causes duplication of resources, but also difficult for relevant managers to clearly control other data such as plant energy consumption and equipment maintenance

In order to meet the requirements of modern urban water supply, realize computerization, digitization and networking, realize "unattended operation" (less people on duty) and remote monitoring, and realize open software and hardware, which play a key communication role in the automatic water supply system. The industrial switches have been put forward higher requirements, which are embodied in:

1. Each water supply unit is decentralized, requiring industrial switches to realize long-distance transmission

2. Industrial switches have high reliability and can run stably for a long time

3. Industrial switches must have good resistance to high and low temperature, dust, moisture, water plant disinfection and oxidation

4. Remote installation of industrial switches supports remote management, fault location, and automatic recovery

5. Industrial switches can provide a reliable redundant network and quickly recover when a fault occurs

6. For video surveillance applications, industrial switches must provide sufficient bandwidth and forwarding performance

7. The industrial switch is installed in an open environment, and high security ensures that the equipment will not be illegally invaded
