[0048] In this embodiment, the visual component is a camera probe.

[0049] The beneficial effects of the above technical solution are:

[0050] By setting the traveling crawler 2, the snow removal device can have stronger mobility on the snow. By controlling the snow removal device to move between different photovoltaic panels to remove snow, it is achieved that one snow removal device can complete the snow removal work of multiple groups of photovoltaic panels. The cost is spread by multiple groups of photovoltaic panels, thereby reducing the construction cost of the snow removal device. By setting the electric telescopic rod 1 5, the working box 6 has the function of lifting and lowering, so that the snow removal device can adapt to photovoltaic panels of different heights. By setting the angle adjustment component, it is ensured that the snow removal device can adapt to photovoltaic panels of different angles. By setting the electric telescopic rod 2 10, the support frame 11 has a telescopic function, which expands the cleaning range of the cleaning component, so that the snow removal device can clean larger photovoltaic panels and expands the range of the snow removal device when it is parked. By the mutual cooperation of the electric telescopic rod 1 5, the electric telescopic rod 2 10 and the angle adjustment component, it is ensured that the snow removal device can maintain a good snow removal effect when facing photovoltaic panels with different postures.

[0051] When the angle of the angle adjustment plate 14 is adjusted, the extension length of the output end of the driving cylinder 16 is controlled to realize the angle adjustment function of the angle adjustment plate 14 in the vertical direction. Through the setting of the visual component 3, the actual image on the travel route can be obtained, which is convenient for planning the travel route of the motion base 1, thereby ensuring the safety of the motion base 1 during the travel process.

[0052] When snow is removed from photovoltaic panels, the moving base 1 is first driven by the traveling crawler 2 to reach the specified position, and the height adjustment of the working box 6 is completed by adjusting the extension of the electric telescopic rod 1 5. Then, the angle adjustment of the angle adjustment plate 14 is achieved by controlling the extension of the driving cylinder 16, so that the angle adjustment plate 14 is adapted to the angle of the photovoltaic panel to be cleaned, and then the extension amount of the support frame 11 is adjusted by adjusting the extension amount of the electric telescopic rod 2 10, so that the cleaning plate 12 is aligned with the area to be cleaned of the photovoltaic panel, and then the electric telescopic rod 3 28 is contracted, so that the control block 26 pops out under the action of the spring 27, so that the center rod 23 is squeezed by the control block 26, so that the control rod 24 squeezes the upper surface of the cleaning plate 12, so that the cleaning plate 12 is in close contact with the surface of the photovoltaic panel, thereby improving the snow removal effect.

[0053] By setting the electric heating wire, the ice layer on the surface of the photovoltaic panel can be melted to avoid damage to the photovoltaic panel when the ice layer is removed. By setting the scraper 29, the maximum cleaning thickness of the snow layer is increased. After the ice layer is melted, the scraping action of the scraper 29 and the cleaning effect of the ice water produced by the melting can complete the cleaning of the stains on the surface of the photovoltaic panel.

[0066] Among them, P i is the snow removal judgment parameter of the i-th photovoltaic panel, V is the current actual snowfall rate; V b is the preset snowfall rate calculation benchmark value; G is the actual light intensity on that day; G b is the preset light intensity calculation benchmark value; ln is the logarithmic function with e as the base; e is a natural constant; τ is the service life influence coefficient; t i is the usage time of the i-th photovoltaic panel; t b is the preset unit attenuation time length; σ is the temperature influence coefficient; T b is the preset rated working environment temperature of the photovoltaic panel; T is the current actual environment temperature; T 0 is the unit temperature value; N 0 is the theoretical maximum power generation of the photovoltaic panel; N i is the actual power generation of the ith photovoltaic panel; max is the maximum value function; N ij is the value of the j-th group of historical power generation of the i-th photovoltaic panel; N i(j-1) is the value of the j-1th group of historical power generation of the i-th photovoltaic panel; M is the total number of groups of historical power generation;

[0067] The screening sub-unit is used to select the photovoltaic panels whose snow removal judgment parameters are higher than the preset snow removal threshold as photovoltaic panels to be snow-removed, and the remaining photovoltaic panels as non-snow-removal photovoltaic panels.

[0068] Preferably, the route planning unit comprises:

[0069] A point determination subunit is used to use the location of the photovoltaic panel to be snow-removed as a working point;

[0070] A positioning and retrieving subunit, used to retrieve the real-time positioning of the motion base 1;

[0071] A road condition retrieval subunit is used to determine the road condition information of the roads in the work site, and the road condition information of the roads includes passable and impassable;

[0075] The traffic determination block is used to determine the passable snow thickness of each road. For a road section where the passable snow thickness is greater than the current snow thickness, the road condition information is passable, otherwise the road condition information is impassable.

[0076] In this embodiment, the actual snowfall rate and the actual light intensity are derived from information released by the meteorological department.

[0077] In this embodiment, the snowfall rate calculation benchmark value and the light intensity calculation benchmark value are both empirical values ​​determined by the work experience of the staff.

[0078] In this embodiment, the service life influence coefficient and the temperature influence coefficient are obtained based on experimental fitting.

[0079] In this embodiment, the service life impact coefficient is the value of the decrease in power generation efficiency of the photovoltaic panel after the photovoltaic panel is used for a specified time period, and the specified time is the unit attenuation time length.

[0080] In this embodiment, the temperature influence coefficient refers to the decrease in power generation efficiency of the photovoltaic panel when the working environment temperature of the photovoltaic panel increases by 1°C.

[0081] In this embodiment, the current snow thickness comes from the information released by the meteorological department.

[0082] In this embodiment, the passable snow thickness of each road is obtained by staff after manual summary based on the historical snowfall thickness and the passable status of the road.

[0083] In this embodiment, the work site is the range where the snow removal device is responsible for snow removal, that is, the photovoltaic panels in the work site are all cleared of snow by the snow removal device.

[0084] The beneficial effects of the above technical solution are:

[0085] By acquiring the real-time positioning of the motion base 1, after the motion base 1 completes the current snow removal task, a new snow removal task is planned according to the current positioning of the motion base 1. There is no need for the motion base 1 to return to the initial position, thereby improving the snow removal efficiency. By automatically judging whether snow removal is required for each photovoltaic panel, a snow removal task is automatically formulated, and then the snow removal device is controlled to automatically perform the snow removal task, thereby realizing the automation of snow removal for photovoltaic panels, improving the snow removal efficiency, eliminating the need for manual intervention by staff, and reducing the workload of staff.

[0086] When determining whether a photovoltaic panel needs snow removal, first determine whether the accumulated snow on the photovoltaic panel has a significant impact on the power generation of the photovoltaic panel based on the deviation between the actual power generation of the photovoltaic panel and the theoretical power generation. Then, determine whether the power generation of the photovoltaic panel has a sudden change based on the historical power generation of the photovoltaic panel, so as to judge whether the photovoltaic panel is damaged. Comprehensively consider the impact of snow accumulation on the power generation of the photovoltaic panel and the judgment of whether the photovoltaic panel is damaged, and then correct it according to the current snowfall rate to obtain the snow removal judgment parameter of each photovoltaic panel. Based on the snow removal judgment parameter of each photovoltaic panel, it is judged whether the corresponding photovoltaic panel needs snow removal, thereby realizing the automation of the judgment of whether the photovoltaic panel needs snow removal. By considering whether the photovoltaic panel is damaged, snow removal of the damaged photovoltaic panel is avoided, thereby reducing the number of photovoltaic panels required for snow removal in the snow removal task and improving the efficiency of snow removal of the photovoltaic panel.

[0087] When planning the working route for snow removal tasks, the traffic condition information of each road is determined according to the current snow thickness, thereby avoiding the mixing of impassable routes in the working route, affecting the snow removal efficiency of the snow removal device, and avoiding damage to the snow removal device when passing through impassable sections, thereby extending the service life of the snow removal device and ensuring the safety of the use of the snow removal device.
