DETAILED DESCRIPTION

[0012] The technical solution of the present invention will be described clearly and completely below in conjunction with the accompanying drawings of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention. Example

[0013] Please see attached Figure 1 , an embodiment of the present invention provides a wind-solar integrated energy storage monitoring system, including a wind-solar complementary power supply system, an RTU transmission system, and a pressure data acquisition system; Please see attached Figure 2 The wind-solar complementary power supply system is used to provide a stable and continuous power supply for the entire pipeline network pressure measuring points; the wind-solar complementary power supply system includes wind turbines, solar panels, wind-solar complementary integrated controller, batteries, and inverters.

[0014] In the wind power generation + solar power generation complementary power supply system, the wind turbine + solar panel are installed on the same pole, with the wind turbine at the top and the solar panel at the bottom. The power supply system also includes a wind-solar complementary integrated controller, battery, and inverter. These devices are all installed in the control box next to the pole, and the control box is installed on the ground.

[0015] The power supply system uses a combination of wind and solar energy, using wind turbines to generate electricity when there is wind, and solar panels to generate electricity when there is sufficient sunshine. Through the intelligent management of the wind-solar hybrid integrated controller, the system can adjust the use of energy according to actual conditions and optimize power output. Through the complementarity of wind and solar energy, the system can continuously and stably provide electricity under different environmental conditions, greatly enhancing the reliability and self-sufficiency of the system. The use of natural resources to generate electricity reduces dependence on traditional energy, reduces energy costs, and also reduces environmental pollution. Since wind and solar equipment generally have a long service life and low maintenance requirements, the maintenance cost and frequency of the entire power supply system are also reduced accordingly.

[0016] Please refer to the attached Figure 3 ,The RTU transmission system is used to send the data collected from the pressure data acquisition system to the central water system platform; The RTU transmission system receives and initially processes analog or digital signals from the pressure data acquisition system through the PLC system, converting them into data formats that can be recognized and processed by the central water system platform. Then, these data are sent to the central control platform through the wireless transmission module to achieve remote monitoring and management of data.

[0017] The RTU transmission system includes a PLC system and a wireless transmission module. The RTU transmission system is also installed in a control box next to the pole. The use of wireless transmission modules enables data to be sent to the central water system platform in real time, helping operators to understand the status of the water network in a timely manner and respond quickly to possible problems or leaks. Wireless communication reduces the need for on-site wiring, especially in areas with complex geographical locations or difficult wiring, significantly reducing installation and maintenance costs. The use of wireless modules makes the system easy to expand and upgrade, and new monitoring points can be easily added or system functions can be updated without large-scale physical changes. Please refer to the attached Figure 4 The pressure data acquisition system is used to measure and collect pressure data in the pipe network; the pressure data acquisition system includes a pressure transmitter and a signal line. The pressure transmitter is installed in a valve or a pressure measuring well, and is connected to a pressure display instrument through a signal line. The pressure display instrument is connected to the PLC system through a signal line.

[0018] The pressure transmitter is installed in the valve or pressure measuring well, and transmits the 4-20mA signal to the pressure display instrument in the control box. The pressure display instrument is connected to the PLC system through Modbus485 communication.

[0019] The pressure transmitter converts physical pressure into an electrical signal, usually a 4-20mA analog signal, which indicates the low to high pressure range. The signal is transmitted to the pressure display instrument through the signal line, and then converted into a digital signal through the Modbus485 interface for further processing and analysis by the PLC system.

[0020] The wind turbine, the solar panel and the wind-solar complementary integrated controller are electrically connected, the inverter and the wind-solar complementary integrated controller are electrically connected, and the wind-solar complementary integrated controller and the battery are electrically connected.

[0021] The use of pressure transmitters can continuously monitor water pressure, ensure the real-time and accuracy of data, and promptly detect leaks or abnormal pressure problems in the system. Through real-time data transmission, the operation team can quickly respond to any problems in the pipe network, reduce maintenance time and costs, and improve service quality and system reliability. Accurate pressure data helps water managers optimize the operation of the entire water supply system, such as adjusting the operation of pump stations, balancing the water pressure of the entire pipe network, and reducing energy consumption.

[0022] Please refer to the attached Figure 5 The wind turbines, solar panels and poles in the pressure measuring points of the wind-solar power generation complementary pipeline are installed on poles with a height of 3m. The wind turbines are at the top and the solar panels are at the bottom. Concrete foundations and embedded parts are provided at the bottom of the poles.

[0023] Please refer to the attached Figure 6 The wind-solar complementary power generation network pressure measuring point includes wind-solar complementary integrated controller, battery pack and inverter. The above equipment is installed in the control box next to the pole. The control box is installed on the ground, and a 50cm concrete foundation is set at the bottom of the control box.

[0024] Please refer to the attached Figure 7 The pressure transmitter is installed on the pipeline in the valve well or pressure measuring well. The pressure transmitter is installed horizontally. The pressure signal is connected to the pressure display instrument in the control box through the 4-20mA communication method. The pressure display instrument communicates with the PLC system in the control box through the Modbus485 bus. Finally, the pressure signal is uploaded to the smart water system platform through the wireless transmission module.

[0025] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
