Introduction
to the remote monitoring system for automatic water supply in water plants In order to improve the efficiency and safety of water supply and reduce the cost of production and operation, the water plant will establish a set of automatic monitoring and auxiliary scheduling system, making it a domestic leading level, with automatic monitoring, real-time production Water supply and distribution projects for systematic management and standardized services.
Through the construction of a modern water supply dispatching system, a pipeline equipment monitoring network and a control communication network are established to ensure that the actual monitoring values of the key points of the water supply system are collected by remote measurement to the dispatch center, and displayed on the computers of each department authorized by the function, so that each department can understand the production situation in real time . Complete real-time monitoring of the running status of water supply pipelines and equipment, and timely collection and sorting of water supply system data to ensure rapid response to system abnormalities and timely deployment of water supply, and then remotely adjust the water supply (or control valve) of the water plant. Make the key points of the water supply system reach the required water quality and water quantity guarantee value. Through centralized management and control, the water supply system operates in the most effective state, reducing energy consumption, reducing resource waste, and improving economic benefits. When accidents such as pipe bursts and water leakage occur in the water supply system, analysis can be made to make reasonable handling decisions to ensure the safe and economic operation of the water supply system.
System design principles
The principle of advancement The
use of advanced design ideas and the selection of advanced transmission equipment will enable the system to maintain technological advancement for a certain period of time in the future.
The principle of openness The
system design and system equipment selection comply with international standards and industrial standards, so that the system has a high degree of openness and the technical compatibility of the equipment provided.
The principle of scalability The
system design fully considers the current situation while taking into account the needs of business development in a relatively long period of time in the future, leaving sufficient possibilities for upgrading and expansion. Make full use of existing communication resources to provide sufficient room for future expansion to higher speeds. On the other hand, there is plenty of room for system expansion.
Security principle
Strengthen the construction of system security, and ensure the long-term stable and reliable operation of the system from multiple aspects such as system security, data security, and network transmission security. The system design has strict security and confidentiality, can ensure that internal information is not stolen, and make full use of the network-level, database-level, document-level, document-area-segment-level, and intra-document domain-level security and confidentiality mechanisms of the development tools to achieve data encryption. , To ensure data security.
Reliability principle
The design of the system implements the reliability principle, so that the transmission system has high availability. The principle of reliability is embodied in the following aspects:
A. Use advanced technology, mature and high-reliability transmission equipment
B. High system gain reserve
C．The maintainability of the link is good
D．It can scan the surrounding magnetic field to provide a basis for the equipment to adjust the frequency in time
The principle of manageability The
system should have good manageability, so that system managers can easily and timely grasp information such as transmission system topology, system signal analysis coverage statistics, system failure prompts, etc., and can easily configure and adjust the transmission system , To ensure that the system is working in good condition.
Economical practicability Make
full use of the current advanced, mature and high-start mainstream modern information technology, introduce and develop a hardware platform with reliable technology and stable performance, and build a good system structure, system interface, information processing technology method and system operation mechanism; make the system It has good adaptability, high advancement and long life cycle. At the same time, economy and practicability are also considered, and the existing resources of the system are fully utilized and protected, and resource utilization is improved.
Standard Normative The
definition of information is unified, the coding is unified, and the national industry standards and norms are implemented.
Design scope The design of
automatic remote monitoring system for water plant , including remote monitoring of water source well, water plant pressurization station, remote monitoring of clean water tank, remote monitoring of pipe network; currently, the water source well pump house uses soft start to control water pumps and water plant pressurized pumps The station uses frequency converter to control the water pump, and the field equipment is already equipped. Now it is necessary to design a remote monitoring system to collect the data of each monitoring point of the field equipment and upload the video data of important points to the monitoring center.
