[0020] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0021] Please refer to Figures 1-2This utility model provides a photovoltaic power collector pole status monitoring system, including a pole attitude monitoring terminal, a meteorological environment monitoring sensor, and a pole status monitoring platform; the pole attitude monitoring terminal is used to detect the current pole's positioning data; the meteorological environment monitoring sensor is used to detect the current environmental meteorological data and is connected to the pole attitude monitoring terminal; the pole status monitoring platform is used to acquire the data collected by the pole attitude monitoring terminal and the meteorological environment monitoring sensor.

[0022] The structure of this utility model mainly includes a tower attitude monitoring terminal, a meteorological environment monitoring sensor, and a tower status monitoring platform. It collects and detects the current tower positioning data and current environmental meteorological data. The tower status monitoring platform acquires the data collected by the tower attitude monitoring terminal and the meteorological environment monitoring sensor. Through this structure, personnel on the tower status monitoring platform can promptly obtain relevant data information, determine whether the tower is tilted, and whether remedial measures are needed. This can largely avoid losses caused by failing to promptly detect the tower's status.

[0023] In one exemplary embodiment of this utility model, the tower attitude monitoring terminal includes a Beidou-3 short message communication unit, a CAT1 communication unit, a single Beidou positioning unit, an MCU processor, an RS485 data acquisition unit, and a power supply unit. The Beidou-3 short message communication unit, the CAT1 communication unit, the single Beidou positioning unit, the RS485 data acquisition unit, and the power supply unit are electrically connected to the MCU processor, and the RS485 data acquisition unit is connected to the meteorological environment monitoring sensor.

[0024] Specifically, the power supply unit includes a solar panel, a BMS control unit, and a battery. The BMS control unit is connected to the solar panel and the battery, respectively, and the battery is connected to the tower attitude monitoring terminal for power supply.

[0025] It also includes a real-time clock and a data storage unit, which are electrically connected to the MCU processor.

[0026] The MCU processor is an STM32H743 microcontroller, the real-time clock is a DS1302, and it is connected to the processor via an I2C bus interface; the data storage unit uses a W25Q254 memory chip, which is connected to the processor via an SPI high-speed bus and communicates with and powers the meteorological and environmental monitoring sensor via an RS485 bus.

[0027] A BeiDou-based pole attitude monitoring terminal is installed on the photovoltaic power line pole, along with meteorological and environmental monitoring sensors. The attitude monitoring terminal acquires real-time single-point position data via a single BeiDou positioning unit and obtains 3-axis acceleration and 3-axis angular velocity data from MEMS sensor units to determine the real-time pole tilt angle. It also acquires environmental wind speed, direction, temperature, and humidity data via an RS485 communication unit. The pole tilt angle and meteorological data are then promptly transmitted back to the pole health monitoring platform via a BeiDou-3 short message communication unit or a CAT1 communication unit. The platform retrieves the current pole attitude data and meteorological data, combining them with historical data to determine if the pole attitude is normal and whether there are any risks of tilting or collapse.

[0028] If a potential hazard is identified, the system will automatically adjust the interval between data transmissions and increase the frequency of data transmissions based on the hazard level, providing timely warnings.

[0029] It is equipped with both a North 3 short message communication unit and a CAT1 communication unit, and features automatic switching of communication channels based on field signal conditions. By default, data is uploaded via the CAT1 communication unit. When the quality of the CAT1 communication is detected to be unsatisfactory, it switches to the North 3 short message communication channel to ensure reliable data transmission.

[0030] An exemplary embodiment of this utility model further includes a vibration sensor, a tilt sensor, and a bolt loosening sensor, wherein the vibration sensor, the tilt sensor, and the bolt loosening sensor are electrically connected to the MCU processor.

[0031] The vibration sensor, tilt sensor, and bolt loosening sensor consist of a MEMS sampling unit, a data processor, a LoRa communication unit, and a power supply system powered by a high-energy battery. The vibration and tilt sensors collect tower acceleration data through the MEMS sampling unit, and calculate the tower vibration and tilt angle after data processing. The bolt loosening sensor collects the bolt's motion posture through the MEMS sensor, and calculates the bolt displacement after data processing. Data from the vibration, tilt, and bolt loosening sensors is transmitted to the MCU processor via the LoRa communication unit.

[0032] Of course, a micro-weather sensor can also be set up to improve data accuracy.

[0033] The vibration sensor is model XY126F100T01C, the tilt sensor is KI NAXN702, and the bolt loosening sensor is VR804. It should be noted that the calculations mentioned above can be output through the existing internal system of the sensors, and do not need to be calculated in this solution.

[0034] Secondly, in this field, sensors are generally installed on towers using clamps. However, these clamps can easily loosen under harsh conditions. Therefore, this embodiment also provides a structure that allows for a more secure installation.

[0035] It includes two symmetrically arranged semicircular clamps 1, with bolt holes at both ends of the semicircular clamps 1 for connection. The two semicircular clamps 1 are detachably connected through the bolt holes and bolts.

[0036] Reinforcing units are provided at both ends of the semicircular clamp 1. Each reinforcing unit includes a connecting rod 2 and a protrusion 4 on the connecting rod. One end of the connecting rod 2 is rotatably connected to the semicircular clamp 1 and connected to the semicircular clamp 4 by a spring 3 for resetting the connecting rod 2. The protrusion 4 is inclined, with its top tilting towards the semicircular clamp 1. A sensor platform 5 is welded to one of the semicircular clamps 1.

[0037] It should be noted that the number of protrusions 4 and the length of the connecting rod 2 can be set according to specific circumstances, and this utility model does not impose any restrictions.

[0038] In use, after securing the two semi-circular clamps 1 to the tower, rotate the two connecting rods 2 towards the semi-circular clamps 1. Then, secure the two semi-circular clamps 1 to the tower with bolts. Loosen the connecting rods 2, and they will reset under the action of the spring 3, with the protrusions 4 on the connecting rods 2 engaging. Even if the bolts loosen, the engagement of the protrusions 2 will temporarily prevent the two semi-circular clamps from separating, buying time for inspection personnel.

[0039] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
