Problems solved by technology
In an open-air working environment, the surface shield will inevitably be polluted by dust, which will block the laser beam trajectory, resulting in data loss and affecting system operation
At present, for the lidar at the high position on the road pole, the dust is usually removed by manual climbing and cleaning. The inventor found that this cleaning method is not only dangerous but also time-consuming and laborious.
At the same time, due to the high position of the lidar, it is difficult to judge the degree of dust pollution of the protective cover by naked eyes, and the standard for cleaning the surface protective cover is determined by the lack of data acquired by the sensor. Whether the dust pollution degree on the surface of the lidar shield meets the cleaning standard and the cleaning process is safe, time-saving, and convenient cleaning device and method

Embodiment 2
[0049] This embodiment discloses a laser radar monitoring device, such as Figure 3-4 As shown, a column 23 is included, and a base 24 is fixed at the bottom of the column, and the base can be fixed on the ground foundation by bolts 25 .
[0050] An L-shaped frame 26 is fixed on the outer peripheral surface of the column, and the L-shaped frame includes a horizontal bar and a vertical bar. One end of the horizontal bar is fixed on the outer peripheral surface of the column, and the other end is fixedly connected with the bottom end of the vertical bar. The top of the vertical rod is fixedly connected with the bottom surface of the laser radar 29, and the laser radar is connected with the control system and can transmit the collected information to the control system.
[0051] The length of the horizontal rod should be equal to the distance between the laser radar and the column to leave room for rotation of the rod and the rectangular iron sheet.
[0052] The horizontal bar i...

The invention relates to a laser radar surface cleaning mechanism and a laser radar monitoring device, comprising a ring part connected to a rotating mechanism, the ring part is provided with a plurality of nozzles capable of spraying cleaning liquid on the surface of the laser radar, and the nozzles are connected to the liquid supply mechanism. It also includes a cleaning cloth that is arranged above the laser radar and connected with the lifting mechanism. The cleaning cloth can move up and down under the action of the lifting mechanism to wipe the outer surface of the laser radar. The cleaning mechanism of the present invention does not require the staff to climb to a high place to manually Clean up, good safety, save time and effort.
Description
technical field [0001] The invention relates to the technical field of transportation engineering, in particular to a laser radar surface cleaning mechanism and a laser radar monitoring device. Background technique [0002] The statements herein merely provide background information related to the present invention and do not necessarily constitute prior art. [0003] The problem of traffic safety has been widely concerned. With the rapid development of computer technology, intelligent transportation system (ITS) emerged as the times require. The system can deploy sensors on vehicles and on the roadside to obtain vehicle and road information, and establish a human-vehicle-road integrated traffic system to improve operational efficiency and safety. [0004] In recent years, the sharp reduction in the price of multi-beam rotating lidar sensors has made it possible to deploy lidar along the roadside to collect road information and improve the transportation system. The common...
