[0031] Example, refer to Figures 1-2A device for detecting snow density includes a load cell and a column 1 fixedly installed on the ground. A collection container for holding snow is installed on the load cell, and the load cell detects the weight of the snow in the container. A snow depth sensor 4 is installed on the column 1, and the snow depth sensor 4 is fixedly installed directly above the collection container. The probe of the snow depth sensor 4 faces the opening of the collection container, and the snow depth sensor 4 detects the depth of snow accumulation in the collection container. A protective box 3 and an off-grid photovoltaic system are installed on the column 1. A data logger is installed inside the protective box 3. The communication and power supply lines of the load cell and the snow depth sensor 4 are connected to the corresponding interfaces of the data logger.
[0032] The off-grid photovoltaic system includes a solar photovoltaic panel group 2 fixedly installed on a column 1. The solar photovoltaic panel group 2 is connected to a controller via cables and connectors. The controller is connected to the DC input terminal of the inverter. The output terminal of the inverter supplies power to the power consumption unit or energy storage device. The power consumption unit includes a snow depth sensor 4, a weighing sensor, and a data logger.
[0033] The weighing sensor includes a base 9, which is fixedly connected to the ground. A bracket 8 is fixed on the base 9, and a mounting ring 5 is fixed on the top of the bracket 8. A wind deflector 6 is fitted on the mounting ring 5. Folded edges 10 are provided on both sides of the wind deflector 6, which are opposite to the weighing sensor.

[0034] The working principle of this application is as follows:
[0035] When it snows, snow accumulates in the collection container on the weighing sensor. The data logger records the weight (m) of the snow and the depth (h) of the snow using the snow depth sensor 4. The bottom area (S) of the container is known and can be input into the data logger during installation or testing. The data logger, using a pre-programmed formula ρ = m / V (V = h * s), instantly outputs the snow density. To prevent interference, if there are unidentified objects in the collection container, the data logger can perform repositioning processing on the weighing sensor and snow depth sensor 4, effectively improving the accuracy of the measurement results. The data logger displays real-time and historical data for snow density, snow depth, and snow weight, and this data can be uploaded to the cloud, allowing users to monitor the data at any time.
[0036] The load cell and snow depth sensor 4 are connected to the data logger. The data logger reads the data from the load cell and snow depth sensor 4 in real time via the Modbus protocol. Then, the density calculation formula is edited in the data logger. The data logger will output the snow density ρ in real time and can save historical snow density data at custom time intervals.
[0037] The above are merely specific embodiments of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. In the absence of conflict, the embodiments and features in the embodiments of this utility model can be combined with each other. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
