Centralized monitoring and management system for water affairs

Abstract

The invention provides a system for centralized monitoring and management of water-related affairs. The system comprises a TCP series intelligent terminal for collection and control of water-related affair data, an NC series intelligent terminal for the collection and control of the water-related affair data, an IO series intelligent terminal for the collection and control of the water-related affair data, water-related affair data receiving gateway equipment, water-related affair data collection gateway equipment, a remote monitoring system and centralized measurement and control gateway equipment for the water-related affairs, wherein the centralized measurement and control gateway equipment receives an instruction for regulation and control, converts the instruction into a corresponding control strategy and then issues the strategy to each data collection and control intelligent terminal, so that remote regulation and control are implemented. The system provided by the invention is characterized in that the dedicated embedded intelligent terminal equipment and the data gateway equipment are used to form the hierarchical data collection system; the system is applicable to various network environments; data of various systems, equipment and instruments can be collected; and a public uniform platform of data collection can be established for water-related affair users.

Description

technical field [0001] The invention relates to the technical field of water affairs monitoring, in particular to a water affairs centralized monitoring and management system. Background technique [0002] At present, there is no mature proprietary system for remote data acquisition and remote control of sewage treatment plants, water plants, pump stations, and monitoring stations. In most cases, the configuration software is deployed on the Internet (or enterprise private network) for remote data collection and remote control, and the general DTU / RTU is used for data communication. The application basis of the configuration software is the industrial network (local area network). The industrial network has a stable network and high security, and the configuration software works well. It is a conventional data acquisition and control system in the industrial field. But in the Internet field, the traditional configuration software + DTU / RTU cannot be well applied on the Inte...

Problems solved by technology

But in the Internet field, the traditional configuration software + DTU / RTU cannot be well applied on the Internet with poor stability and security (compared to the industrial network). The traditional method has the following problems:

[0003] (1) The reliability of data transmission is poor: because the configuration technology originated from the industrial network, the industrial network is a wired LAN, the network topology is single and stable, while the Internet network environment is complex, and there are wireless (including GPRS, 3G, etc.) network paths, the configuration The original data transmission technology of the software cannot fully adapt to the Internet, and it is prone to connection interruption or data loss. The current DTU / RTU products are mostly general-purpose products for transparent transmission, with small storage capacity, and cannot realize reliable breakpoint resume transmission;

[0004] (2) The industrial database supports poor data comprehensive analysis capabilities: the configuration software uses the industrial database to store real-time data, and the industrial database is used to store massive real-time data. It adopts linear compression storage technology, and the storage mechanism is variable storage. In addition, the data storage unit is " variables" one record per variable

This mechanism has great support for vertical extraction such as real-time monitoring, historical analysis, and multivariate comparative analysis. However, it does not support direct access for multi-dimensional analysis such as multi-site index query, comparative analysis, and statistical analysis, and requires a lot of intermediate processing. Development Complexity, low efficiency, and long human-computer interaction time;

[0005] (3) Remote control is unreliable: the configuration software is real-time control software, which requires a stable and fast network channel, but the Internet network environment is complex, and there are wireless (including GPRS, 3G, etc.) network paths, the network is unstable, and the packet loss rate is high. High, the control commands of the configuration software cannot be delivered and fed back in time, and its original remote control mechanism is prone to errors;

[0006] (4) Data standardization is not possible: the configuration software uses a variable storage management mechanism, DTU / RTU is transparent transmission, variables are self-defined by automatic control engineers, variable definitions cannot contain too many business concepts, and the configuration process cannot achieve data indicators definition, management and standardization, which is not conducive to the subsequent comprehensive analysis of online data;

[0007] (5) Data preprocessing is not possible: Based on the configuration software function and the variable storage mechanism of the industrial library, the configuration software and DTU / RTU cannot realize complex formula calculation, data statistics summary, feature data extraction and other data preprocessing functions at the acquisition front end
