Solution for Remote Supervision Platform of Rural Domestic Sewage

1.1 Current situation of rural domestic sewage

50% of the polluted water in our country comes from rural domestic sewage. The main reason for this problem is that rural domestic sewage is directly discharged into rivers or outdoor open spaces without purification treatment, and then seeps into the ground at will. A small portion of it is simply treated in septic tanks and seeps into the ground at will, seriously polluting river and well water, causing some rivers and ponds to become natural sewage collection tanks. At present, most of the houses in rural areas of China are self built houses, which have significant arbitrariness and lack a reasonable overall layout plan.

The level of rural economic development is relatively backward, and the corresponding infrastructure construction is not in place. The pollution caused by rural domestic sewage is not only a potential safety hazard for rural water sources, but also exacerbates the shortage of freshwater resources. The crisis of arable land cannot be effectively alleviated, thereby endangering the survival and development of rural areas. Governance work not only involves building sewage treatment facilities, but also focuses on improving the operational management level and equipment efficiency of the already constructed facilities. The rural sewage treatment system consists of a large number of standardized buried treatment equipment, which have fixed process flow, are small and scattered, and require maintenance personnel to be present for inspection and maintenance, which is inconvenient, untimely, and has huge operation and maintenance costs.

1.2 Pain points in rural domestic sewage treatment

Multiple sites, large volume, wide coverage, and remote location

There are many rural sewage treatment stations, with a large area and scattered locations, which makes it difficult for administrators to quickly and effectively monitor and manage. However, traditional methods of supervision and inspection rely on manual on-site inspections, human brain memory, and paper-based input, which takes a long time and wastes manpower and material resources.

Unable to provide timely feedback and handling of on-site faults

When the equipment malfunctions, on-site maintenance personnel need to proactively detect the equipment failure, fail to monitor the equipment in a timely manner, have a low level of automation, cannot effectively allocate equipment resources, and equipment maintenance and inspection are not in place.

Lack of complete system monitoring data support and scientific statistical and analytical methods;

Lack of operation and maintenance skills and talents, emphasizing construction over operation

The maintenance personnel of the site are usually local farmers, lacking environmental knowledge and skills in equipment operation and management. Only responsible for the daily maintenance of equipment, unable to handle professional level system maintenance. Due to inadequate management personnel and lack of technical personnel, most of the engineering equipment is left unattended after construction, resulting in decoration.

Unable to objectively assess operation and maintenance personnel, achieving traceability and traceability of maintenance issues, in order to consolidate operation and maintenance responsibilities

The operation and maintenance personnel have been operating outside for a long time, and the management personnel are unable to timely know whether the operation and maintenance personnel are working effectively and whether the operation and maintenance of the equipment are handled properly. There is no reasonable assessment mechanism in place, and some places use paper-based assessment methods. There are many human factors, and there are many complaints during the year-end assessment. Implementing staff responsibilities and improving operational efficiency are the key to agricultural pollution projects.

Real time collection of video streams from a single sewage treatment station is possible, and based on the overall situation of the sewage treatment station, the video can be pan tilt controlled and historical playback can be viewed, providing a comprehensive understanding of the overall situation of the sewage treatment station.

(8) Continuous transmission after network interruption and offline caching

When the network is unstable, the gateway can still collect device data normally and store historical data in the gateway Flash. After the network is restored, the gateway will send data to the platform on its own to ensure the continuity and integrity of historical data to the greatest extent possible;

(9) BI big data visualization

Users can independently edit and create BI data display screens, which are displayed in graphical controls such as reports, bar charts, pie charts, line charts, radar charts, videos, and maps. Realize the overall operation status of project energy consumption, water treatment capacity, fault statistics, operation and maintenance statistics, personnel statistics, etc. The management platform can display the real-time status of instantaneous and total water flow, and can conduct monthly and annual statistics and output reports. Can statistically analyze and generate reports on the sewage treatment capacity, water quality, and operating status data of power pumps for each equipment.

(10) Ledger&Operations

Record and view equipment name, model, purchase date, service life, depreciation period, serial number, and technical information. Generate repair and maintenance work orders and develop inspection plans based on the causes of equipment failures and maintenance plans.

(11) Multi user permissions&operation logs

Multiple types of accounts can be created through functional and data permissions (such as engineers, operators, operations and maintenance, factory managers, supervisors, etc.), and operation logs can be generated for important operations (such as parameter settings, equipment startup and shutdown).

(12) Intelligent province traffic description

On demand data transmission, data change uploading, historical data packaging and uploading, and client access for quick refreshing. Only historical data and alarm data are transmitted in non access state. On the basis of ensuring a friendly experience, save the cost of data card traffic.

(13) High performance edge computing, local data processing

It can directly parse, judge, count, clean (redundant data) and execute policies (implemented through script programming) on device data, achieving timely and accurate processing of data on the edge side (gateway/controller), saving data traffic and storage space, and reducing platform load.

(14) Real time/historical trend, alarm query function

It can be queried based on time periods, monitoring areas, monitoring points, and monitoring values, and historical data can be output in tables and graphs. Various reports, query information, and alarm information can be displayed and printed out on the screen.

(15) GIS map function

Each sewage station can display its distribution coordinates through electronic maps on the platform software. It can display the real-time operation status of each site (online, offline, fault). You can quickly reach the installation site through navigation.
