Water centralized measurement and control gateway device

Abstract

The present invention proposes a centralized measurement and control gateway device for water affairs, which includes: a data transmission module that receives regulation instructions from the remote monitoring system; a control strategy management module that converts the regulation instructions into corresponding control strategies; a data transmission module that converts the The control strategy is sent to the corresponding intelligent terminal for water data collection and control, and the intelligent terminal for water data collection and control sends the control parameters to the corresponding equipment and meters to realize the regulation of the equipment and meters, and the data transmission module also receives The device feedback data from each of the water data collection and control intelligent terminals. The invention receives the regulation command of the remote monitoring system, converts it into a control strategy, and sends it to each intelligent terminal for data collection and control of water affairs, so as to realize the remote centralized control under the Internet environment.

Description

technical field [0001] The invention relates to the technical field of water treatment and gateway equipment, in particular to a water centralized measurement and control gateway equipment. Background technique [0002] At present, there are no mature proprietary systems for remote data acquisition and remote control of sewage treatment plants, water plants, pumping stations, and monitoring sites. In most cases, configuration software is deployed on the Internet (or enterprise private network) for remote data acquisition and remote control. , use common DTU / RTU for data communication. [0003] The application basis of the configuration software is the industrial network (local area network). The network of the industrial network is stable and safe, 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 ...

AI Technical Summary

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 industrial networks), and there are the following problems:

[0004] (1) The reliability of data transmission is poor: because the configuration technology originated from the industrial network, the industrial network is a wired LAN, and the network topology is single and stable, but the Internet network environment is complex, including wired and wireless (including GPRS, 3G and other communication methods) network paths

The original data transmission technology of the configuration 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 with transparent transmission, and the storage capacity is small, so reliable breakpoint resume cannot be realized.

[0005] (2) The industrial database supports poor comprehensive data 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, using linear compression storage technology, and the storage mechanism is change storage

This mechanism has great support for vertical extraction such as real-time monitoring, historical analysis, and multivariate comparative analysis, but 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. The disadvantages of complex development, low efficiency, and long human-computer interaction time

[0006] (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 includes wired and wireless (including GPRS, 3G and other communication methods) network paths, and the network is unstable. The packet loss rate is high, causing the control commands of the configuration software to not be delivered and fed back in time, and the original remote control mechanism is prone to errors

[0007] (4) Data standardization is not possible: the configuration software uses a variable storage management mechanism, DTU / RTU is transparent transmission, variables are defined by the automatic control engineer, and variable definitions cannot contain too many business concepts, resulting in the inability to realize data security during the configuration process Index definition, management and standardization are not conducive to the follow-up comprehensive analysis of online data

[0008] (5) Unable to perform data preprocessing: Based on the configuration software functions and the variable storage mechanism of the industrial library, the configuration software and DTU / RTU cannot realize data preprocessing functions such as complex formula calculation, data statistics summary, and feature data extraction at the front end of the acquisition
