Technical Field

[0002] With the rapid development of photovoltaic power generation technology, traditional rigid photovoltaic systems are facing problems such as tight land use, high construction costs, and poor environmental adaptability. Especially in the complex terrain environment of western regions, the construction difficulty and cost have increased significantly. To address this, the industry has developed flexible photovoltaic systems.

[0003] Flexible photovoltaic (PV) systems utilize flexible PV support structures. These structures consist of cables tensioned between two fixed points, with rigid foundations providing reaction forces. Flexible PV support systems allow for large-span installations and can overcome unfavorable geographical factors such as undulating terrain and high vegetation cover, thus exhibiting good environmental adaptability, alleviating land use pressure, and reducing construction costs. However, the complex structure of flexible PV support systems and the lack of effective condition monitoring methods make it difficult for users to monitor the status of the flexible PV system, detect potential problems in a timely manner, and match suitable operation and maintenance solutions. This results in low operation and maintenance efficiency, low overall performance, and a shorter lifespan for the flexible PV system.

[0004] Therefore, it is necessary to effectively monitor the status of flexible photovoltaic systems. Existing monitoring equipment is bulky, difficult to install, energy-intensive, and cannot flexibly switch monitoring elements according to the requirements of the installation site, thus failing to meet the status monitoring needs of flexible photovoltaic systems. In view of this, how to develop a monitoring device that can meet the status monitoring needs of flexible photovoltaic systems is a technical problem that needs to be solved by those skilled in the art.

[0026] This application provides an intelligent monitoring terminal for a flexible photovoltaic system. To enable those skilled in the art to better understand the technical solution of this application, the following description is provided in conjunction with the appendix. Figure 1-6 The technical solutions of this application will be further described in detail below with reference to specific embodiments.

[0027] like Figure 1 As shown, the intelligent monitoring terminal of the flexible photovoltaic system includes a microcontroller 100 and a data acquisition unit 200. Figure 1(Not shown in the text).

[0028] The microcontroller 100 includes a housing 101, a processing module 102 (located inside the housing 101), and a data acquisition interface 103 (see...). Figure 3 The microcontroller 100 is small in size, lightweight, easy to install, and has low power consumption. Specifically, in the illustrated embodiment, as shown... Figure 4 and Figure 5 As shown, the housing 101 of the microcontroller 100 is a cuboid measuring 130mm × 130mm × 40mm. The power consumption of the microcontroller 100 can be controlled below 5W. The power input of the microcontroller 100 can be DC 9~36V, and the output can be 5V or 12V. Specifically, the housing 101 of the microcontroller 100 can be provided with connection holes 108. In use, the microcontroller 100 can be directly fixed to the bracket of the flexible photovoltaic system by threaded fasteners passing through the connection holes 108. In the figure, connection holes 108 are provided at all four corners of the cuboid housing 101.

[0029] The acquisition unit 200 is used to acquire target elements. Specifically, the target elements include environmental elements of the flexible photovoltaic system and elements of the flexible photovoltaic system itself. More specifically, the environmental elements of the flexible photovoltaic system include, but are not limited to, light intensity, temperature, wind speed, and humidity. The elements of the flexible photovoltaic system itself include, but are not limited to, displacement, vibration, stress, anchoring force of the load-bearing cable and the support body, strain of the load-bearing cable, deflection of the load-bearing cable, and tilt angle of the photovoltaic panel.

[0030] The acquisition unit 200 is plugged into the acquisition interface 103 to achieve plug-and-play functionality. This allows for flexible switching of acquisition elements according to the needs of the flexible photovoltaic system installation site. For example, when some installation sites do not need to acquire light intensity but need to acquire humidity, the acquisition unit 200 that can acquire light intensity can be replaced with the acquisition unit 200 that can acquire humidity.

[0031] The processing module 102 is connected to the acquisition unit 200 via the acquisition interface 103. The processing module 102 is also connected to the remote monitoring platform via the communication module 104. In this way, the processing module 102 can process the data collected by the acquisition unit 200 and transmit the processed data to the remote monitoring platform, thereby enabling remote monitoring of the status of the flexible photovoltaic system. This allows the remote monitoring platform, as an operation and maintenance platform, to promptly match a reasonable operation and maintenance plan for the flexible photovoltaic system and improve operation and maintenance efficiency.

[0032] The intelligent monitoring terminal for the flexible photovoltaic system provided in this application is small in size, easy to install, and has low energy consumption. It can flexibly switch monitoring elements according to the requirements of the flexible photovoltaic system installation site, and can realize remote real-time monitoring of the status of the flexible photovoltaic system. This allows for timely understanding of the status of the flexible photovoltaic system, timely detection of potential problems, and timely matching of reasonable operation and maintenance solutions for the flexible photovoltaic system. This can ensure the operation and maintenance efficiency and overall effectiveness of the photovoltaic power station, as well as the service life of the flexible photovoltaic system.

[0033] In some embodiments, the acquisition unit 200 is an integration of one or more of the following: wind sensor, solar radiation sensor, temperature and humidity sensor, acceleration sensor, vibration sensor, tilt sensor, tension / compression sensor, vibrating wire anchor cable sensor, vibrating wire strain sensor, and laser rangefinder. The monitored elements may vary depending on the specific application requirements; therefore, in practical applications, the type of sensing element in the acquisition unit can be flexibly adjusted according to needs, rather than being limited to the aforementioned types.

[0034] In some embodiments, the acquisition interface 103 includes interfaces of various standards to support acquisition units 200 with different connectors. Specifically, it may include RS standard interfaces, such as RS485 and RS232 interfaces, which are generally compatible with the MODBUS RTU protocol. It may also include CAN standard interfaces, which are generally compatible with the CAN protocol. Furthermore, the acquisition interface 103 includes digital signal input interfaces and analog signal input interfaces to support acquisition units 200 with digital output signals and acquisition units 200 with analog output signals.

[0035] In some embodiments, the communication module 104 includes a wireless communication module and a wired communication module. Specifically, the wireless communication module 104 can be a mobile communication module and / or a Wi-Fi module. The mobile communication module can specifically be a 4G module, a 5G module, etc. The mobile communication module 104 includes a SIM card slot 1041 and an antenna 1042. The wired communication module 104 can be an Ethernet module and / or a fiber optic module. When a wired communication module 104 is provided, a wired interface needs to be provided on the microcontroller 100.

[0036] In some embodiments, the microcontroller 100 further includes a display module 105, which is communicatively connected to the processing module 102 and can indicate the working status of the intelligent monitoring terminal, thus helping users quickly understand the operating status of the intelligent monitoring terminal. Specifically, the display module 105 can be a display screen or indicator lights 1051, etc. In the illustrated embodiment, the display module 105 includes five indicator lights 1051, which respectively indicate the power-on status, operating status, communication connection status between the processing module and the remote monitoring platform, communication connection status between the processing module and the acquisition unit 200, and fault status of the intelligent monitoring terminal.

[0037] In some embodiments, the microcontroller 100 further includes a debug interface 106 and a switch 107. The debug interface 106 is used to connect a debug device for debugging the microcontroller 100. The switch 107 is used to turn the microcontroller 100 on and off.

[0038] In some embodiments, the microcontroller 100 includes a local configuration module and an online update module. This enables and supports online updates and local configuration, ensuring that the microcontroller 100 can be continuously upgraded to adapt to changing monitoring needs.

[0039] In some embodiments, the intelligent monitoring terminal includes a power supply unit 300, which is electrically connected to the power-consuming components of the intelligent monitoring terminal. The power supply unit 300 can draw power from mains power, flexible photovoltaic systems, or emergency power equipment, thus ensuring that the intelligent monitoring terminal can still operate normally in low-light environments such as cloudy days.

[0040] In some embodiments, the power supply unit 300 may include a battery, thus ensuring that the intelligent monitoring terminal has a long battery life. The battery is preferably disposed independently outside the housing 101 of the microcontroller 100, thus avoiding the problem of increased size of the microcontroller 100 leading to installation difficulties.
