Environmental Protection Case Introduction

1. Project overview

1.1 Project goals

Remotely monitor the operation status of integrated sewage treatment equipment in various regions of the country, and realize remote operation and maintenance management of all equipment types. As the equipment is scattered throughout the country, belongs to different water companies, and the number of equipment is increasing, adding equipment and data to the existing system has great limitations, and system maintenance and new functions are inconvenient. The added process flow of the existing system is not configurable and requires high programming for maintenance personnel. Therefore, in order to improve the management level and efficiency of integrated sewage treatment equipment, a configurable development webpage and APP platform software development is needed to realize all the functions of the existing system. Therefore, it is necessary to establish a set of integrated sewage treatment equipment centralized monitoring system with unobstructed information and reliable operation to monitor the operation information of integrated sewage treatment equipment under its jurisdiction and the operation status of statistical analysis equipment in real time, and help the water department to make efficient, fast and accurate To realize unattended integrated sewage treatment equipment, unified dispatch and command, improve management efficiency, save operating costs, and ensure efficient, safe and stable operation of the entire equipment. The main implementation content of the integrated sewage treatment equipment centralized monitoring project includes geographic information function, operation monitoring of each integrated equipment, remote control, list display, trend curve, video monitoring, system alarm, report analysis, operation log, production management, authority management And functions such as mobile APP and system security.

Informatization of asset management Establish a unified basic information database to realize the information management of sites, assets, operation and maintenance personnel and other information in one station, realize the full life cycle management of site assets, and improve the effective management of site resources.

Visualization of operating conditions

Establish a visualized remote centralized monitoring platform to realize remote centralized monitoring and intelligent alarming of the site's import and export water quality, operating conditions (fans and pumps operating status, water level, flow), video images, and other data, and improve the efficiency of handling abnormal emergencies. Site sewage treatment rate and effluent compliance rate.

Operation and maintenance supervision standardization

Establish a scientific operation and maintenance management system, realize scientific supervision of operation and maintenance work from daily operation and maintenance work specifications, processes, and systems, and realize closed-loop management of operation and maintenance events, thereby improving the quality and efficiency of operation and maintenance work.

Digital quality assessment

Establish a multi-dimensional digital quality assessment system to provide efficient digital assessment methods for the assessment and evaluation of the quality of domestic sewage treatment in villages and towns.

3. Functional modules and user interface

3.1 Data collection and storage

The data collector collects the data of the underlying equipment and saves it to the database of the cloud server deployed by Haoyuan Environmental Protection. The real-time industrial database saves and processes continuous industrial process data with time stamps, and the relational database (MYSQL, mongodb) saves and processes entity Business data with relational structure.

3.1.1 Core data collection program

The data collection function should be able to realize the data collection in the production and operation process, and the collected data content includes: automatic control real-time data, manual data entry.

3.1.2 Real-time data collection scheme

The IOServer acquisition software platform, as an independent data acquisition platform, realizes the data acquisition of more than 4000 kinds of equipment; supports multiple databases and multiple storage methods, and provides standardized and unified data for third-party software or data acquisition monitoring platforms source.

The IOServer acquisition platform used in this solution realizes the on-site sensing and execution of data uploading and acquisition from the secondary on-site pre-data acquisition gateway to the PLC and intelligent instrumentation. Real-time data is divided from its source, divided into equipment-generated and calculated. The real-time data generated by the equipment is mainly collected by the IOServer. The calculation results generally refer to the calculation results generated by the SCADAServer, and no additional collection is required.

In this project group, IOServer directly collects equipment process data and production working condition data from the secondary platform data collection gateway. The calculated data is calculated and stored by KingSCADA and King Portal and databases deployed on the cloud server.

3.1.3 Historical data storage

According to the current product description requirements for data storage, the Historian of the system needs to store a variety of data (real-time data, alarm events, annotations), needs to support the storage requirements of structured data (structured based on time series), and at the same time, in order to improve the query Efficiency, added feature value data (mainly for query of trend curves) and query cache.
