[0002] In recent years, people's lives have improved, and the discharge of rural domestic sewage has continued to increase. With the strengthening of environmental protection efforts, more and more rural domestic sewage treatment plants have been put into construction and operation. During the operation of sewage treatment plants, it is crucial to monitor relevant data such as equipment operation, plant appearance, plant safety, and operating parameters (including influent flow, blower aeration, and chemical dosage), control equipment operation status, and manage the plant in a unified manner.

[0003] Currently, wastewater treatment plant supervision typically requires on-site monitoring by supervisors, making remote monitoring impossible. This prevents personnel other than on-site supervisors from promptly monitoring the operational status and key data indicators of the plant's pumping equipment, and hinders unified management of multiple wastewater treatment plants, resulting in significant monitoring costs. Therefore, achieving remote monitoring of wastewater treatment plant equipment operational indicators while saving manpower and reducing costs is a pressing technical problem that needs to be solved.

[0036] Currently, wastewater treatment plants are generally monitored on-site by supervisors. This method cannot provide real-time monitoring of the plant and pumping station equipment's operational status for personnel other than the supervisors, nor can it create a comprehensive monitoring perspective. Furthermore, it cannot respond promptly and resolve issues when equipment malfunctions or other abnormalities occur. In existing technologies, each wastewater treatment plant requires its own supervisors, making unified and centralized monitoring and management of equipment at different plants impossible. This increases the workload for staff, wasting manpower and time, reducing efficiency, and increasing equipment maintenance costs. To address these problems, this application discloses a remote monitoring system for wastewater treatment plants. This system enables remote monitoring of equipment operating indicators at wastewater treatment plants, significantly saving manpower and reducing costs.

[0037] In the following description, embodiments of the present invention will be illustrated with reference to the accompanying drawings. In the drawings, the same reference numerals denote the same or similar parts.

[0039] In this embodiment, such as Figure 3As shown, the control device 300 receives the operating parameters of the field equipment 100 and the field images of the wastewater treatment plant acquired by the image acquisition device 200, and sends the received operating parameters and images to the monitoring device 500 through the communication device 400. The display module 510 of the monitoring device 500 then displays the operating parameters and images, thereby realizing the visualization of the operating status of the relevant equipment of the wastewater treatment plant. This system enables the centralized display of the operating parameters and images of the field equipment of different wastewater treatment plants, and can realize the centralized monitoring of multiple wastewater treatment plants, thereby saving manpower and improving the efficiency of monitoring.

[0040] Specifically, the wastewater treatment device 130 can be an integrated wastewater treatment equipment, and the wastewater treatment device 130 is used to treat wastewater. The blower 120 is used to provide oxygen required for wastewater treatment. The water pump 110 is used to transport wastewater and sludge into the integrated wastewater treatment equipment.

In one embodiment, the output end of the water pump 110 is connected to the inlet of the sewage treatment device 130, the output end of the blower 120 is connected to the input end of the electric valve 140, the output end of the electric valve 140 is connected to the air inlet of the sewage treatment device 130, the output end of the dosing device 150 is connected to the dosing port of the sewage treatment device 130, the flow meter 180 is installed on the inlet and outlet pipes of the sewage treatment device 130, and the level gauge 160 and the dissolved oxygen meter 170 are both located inside the sewage treatment device 130.

[0041] In one embodiment, the image acquisition device 200 may be a camera used to monitor video footage from the field equipment 100 at the wastewater treatment plant; furthermore, to improve the clarity of the acquired field video, the camera may specifically be a high-definition camera. It is understood that this embodiment of acquiring images or videos of the field equipment 100 based on a camera is merely an example; that is, the image acquisition device may be a sensor, etc., in addition to a camera.

[0042] Furthermore, the control device 300 includes a control cabinet 310 and a video monitoring cabinet 320. The control cabinet 310 is connected to the field device 100, and the video monitoring cabinet 320 is connected to the image acquisition device 200. Figure 2 As shown, each field device 100 is connected to the control cabinet 310 via cables, and the image acquisition device 200 is also connected to the video monitoring cabinet 320 via cables.

[0043] For example, the control cabinet 310 includes a PLC controller 311, a relay 312, and a data acquisition module. The water pump 110, blower 120, electric valve 140, and dosing device 150 are all connected to the relay 312, and the level gauge 160, dissolved oxygen meter 170, and flow meter 180 are all connected to the data acquisition module. In this embodiment, the relay 312 is used to control the water pump 110, blower 120, electric valve 140, and dosing device 150 based on the control signals sent by the PLC controller 311, and the data acquisition module is used to receive data collected by the level gauge 160, dissolved oxygen meter 170, and flow meter 180. In some other embodiments, in addition to the PLC controller 311, relay 312 and data acquisition module, the control cabinet 310 may also include a power supply module 313, touch screen 314, control switch 315, terminal block 316, RS485, switch 331, gateway 332, analog expansion module 317, etc., to meet the application requirements of different types of water treatment equipment and facilitate the parameter configuration and on-site debugging of the field equipment 100.

[0044] In one specific embodiment, the control cabinet 310 includes a first housing, in which the PLC controller 311, relay 312 and data acquisition module are all located, and the first housing has a ventilation opening 318; in this embodiment, the control cabinet 310 is packaged into an integrated structure based on the first housing, which can improve the structural compactness of the control cabinet 310. Figure 5 This is a schematic diagram of the control cabinet of a remote monitoring system for wastewater treatment plants according to an embodiment of the present invention. Figure 5 As shown, when the control cabinet 310 also includes a power module 313, a touch screen 314, a control switch 315, a terminal block 316, an RS485, a switch 331, a gateway 332, and an analog expansion module 317, the first housing is provided with a touch screen mounting hole and a control switch mounting hole, and the power module 313, the switch 331, the gateway 332, the terminal block 316, and the analog expansion module 317 are all encapsulated in the first housing.

[0045] Similarly, the video surveillance cabinet 320 includes a second housing, in which the switch 331, the recorder 321 and the router 322 are all located. Figure 4 This is a schematic diagram illustrating the image transmission of a remote monitoring system for wastewater treatment plants. Figure 4As can be seen, the images acquired by the on-site image acquisition device 200 sequentially pass through the switch 331, recorder 321, and router 322 within the video monitoring cabinet 320, and are then transmitted to the monitoring device 500 via the external communication device 400. It is understandable that the video monitoring cabinet 320, which integrates the switch 331, recorder 321, and router 322, can realize the reception, processing, and transmission of video images.

[0046] Additionally, the communication device 400 may include an NB-IoT communication module, which is the core of communication between the control device 300 and the monitoring device 500, serving as the main data channel. That is, the control device 300 not only transmits received data to the monitoring device 500 via the communication device 400, but the monitoring device 500 can also send equipment operating parameters to the control device 300 via the communication device 400. Furthermore, the communication device 400 can collect and process data based on a server. In some embodiments of the present invention, the monitoring device 500, in addition to including the display module 510, also includes a terminal device 520, which is used to send control signals to the control cabinet 310. For example, the terminal device 520 may be a mobile phone, tablet, or computer. In some embodiments, the terminal device 520 may be equipped with corresponding operating software. Based on this software, the operating data and on-site video footage of the relevant field equipment 100 at the wastewater treatment plant can be displayed. Furthermore, the terminal device 520 can also remotely control the field equipment 100 at the wastewater treatment plant. Therefore, in some embodiments, the monitoring device 500 can achieve real-time monitoring, management, and early warning functions for the operation of the wastewater treatment plant. In other embodiments, the monitoring device 500 may also include a UPS power supply, a network switch 331, and a video server.

Both pump 110 and the integrated wastewater treatment unit are equipped with flow meters 180 at their rear ends to monitor the inflow and outflow of the integrated wastewater treatment unit. Pump 110, flow meters 180, and the integrated wastewater treatment unit are connected sequentially via pipelines. Blower 120 and dosing equipment are located in the equipment room and are also connected to the integrated wastewater treatment unit via pipelines. Blower 120 and dosing equipment are used for oxygen and chemical agent delivery during wastewater treatment. Additionally, blower 120 is equipped with an electric valve 140 at its rear end to control the aeration rate. Dissolved oxygen meter 170 and level gauge 160 are located inside the integrated wastewater treatment unit, used for high and low water level monitoring and dissolved oxygen data monitoring, respectively. All field devices 100 are connected to control cabinet 310 via cables. Control cabinet 310, located in the equipment room, is used for receiving, processing, and controlling signal data from the field devices 100. A high-definition camera is located at the wastewater treatment plant site and connected to the video monitoring cabinet 320 via cable for monitoring the wastewater treatment plant. The control device 300 and the monitoring device 500 are connected via network operator equipment (communication device 400) and Ethernet communication to transmit on-site data to the monitoring device 500. The monitoring device 500 may include a network switch 331, a video server, a terminal device 520, and a display module 510.
