The invention relates to a position adjusting system for heliostat cleaning equipment. The position adjusting system comprises a multi-freedom-degree adjusted hydraulic lazy arm arranged on a cleaningvehicle chassis, an adjusting device arranged on a first framework, a distance detection device arranged on the side, close to the heliostat face, of a cleaning vehicle, and a parallelism degree detecting device arranged on the first framework. The first framework is connected with a framework installing position of the hydraulic lazy arm through a connecting base at the middle portion of the upper side of the first framework. The first framework is provided with an installing plate. The adjusting device is used for adjusting the position of a brush arranged on the installing plate relative to the heliostat face. The hydraulic lazy arm and the adjusting device adjust the positions of the first framework and the brush according to signals fed back by the parallelism degree detecting device, and a driver adjusts the running direction of the cleaning vehicle according to the signals fed back by the distance detection device. The cleaning angle is automatically adjusted, convenience and flexibility are achieved, cleaning is clean, thorough and free of dead angles, the cleaning efficiency is high, and the service life is long.

The invention relates to a pure-electric sanitation sweeping vehicle and an automatic driving system thereof. The automatic driving system comprises a power battery, a control module, a vehicle body peripheral obstacle detecting subsystem, a roadside distance detecting subsystem, an electric-control steering subsystem and a braking subsystem. The situation of obstacles around a vehicle body is detected by the vehicle body peripheral obstacle detecting subsystem, the distance between the vehicle and the roadside is detected by the roadside distance detecting subsystem, in the automatic drivingprocess, the vehicle is automatically controlled to travel according to the situation of the obstacles around the vehicle body and the distance between the vehicle and the roadside, when normal traveling of the vehicle is affected by the obstacles or the vehicle is too close to the roadside, the vehicle steering subsystem or the braking subsystem is controlled to achieve steering or decelerating of the vehicle, thus the obstacles are avoided or the distance between the vehicle and the roadside is increased, and safe and reliable operation of automatic driving is achieved. Therefore, automaticdriving control over the pure-electric sanitation sweeping vehicle can be achieved through the automatic driving system.

The invention relates to an automatic focusing device for a linear scanning automatic optical detection system, and the device comprises an optical detection equipment fixing module which is used for fixing optical detection equipment; the wafer lifting bearing module is used for bearing a wafer and driving the wafer to move, and the wafer lifting bearing module is located below the optical detection equipment; and the distance detection module is arranged in the automatic focusing device and can detect the position of the spacing distance between the wafer and the optical detection equipment, and the distance detection module is connected with the wafer lifting bearing module. According to the automatic focusing device, focusing is achieved by fixing the optical detection equipment and adjusting the position of the wafer through the wafer lifting and bearing module, the wafer can be better shot, the setting time is effectively shortened, the optical detection equipment can complete focusing more quickly, and due to the fact that the overall structure of the wafer is light, the wafer is convenient to adjust. And large inertia cannot be generated in the vertical direction, so that the requirement on the torsion of the brake motor is reduced.

The invention provides a false color laser radar system. The false color laser radar system comprises a wide-spectrum light receiving and transmitting device, a color separation prism combination, a data acquisition system and a control system which are connected in sequence, wherein a control unit is used for controlling the wide-spectrum light receiving and transmitting device to emit radar beams to a target object for illumination; the wide-spectrum light receiving and transmitting device transmits an echo light signal reflected by the target object to the color separation prism combination; the color separation prism combination divides the echo light signal into a plurality of spectrum channels according to wavelengths; and the control unit further processes and synthesizes the light beams of the plurality of spectrum channels acquired by the data acquisition unit to obtain false color point cloud data. According to the false color laser radar system, the echo light signal is divided into the plurality of spectrum channels according to the wavelength by using the color separation prism combination, the structure is simple, and compared with a hyperspectral light splitting mode with the channel width of 10 nm, the selection channel width of the color separation optical filter is not less than 100 nm, higher light pulse energy in the channel can be received, and the technical advantage of long-distance detection is achieved.

The invention discloses a body movement state monitoring method and a body movement state monitoring device. The body movement state monitoring method is applied to a chip of a monitoring device, and the monitoring device further comprises an upper electrode plate, an elastic interlayer and a lower electrode plate. The method comprises the steps that when a monitored object generates pressure on the monitoring device, the pressure is detected according to corresponding deformation generated by the elastic interlayer and the distance between the upper electrode plate and the lower electrode plate; recording the pressure area and the pressure position of the pressure in a set time period; and determining the body movement state of the monitored object according to the pressure area and the pressure position of the pressure in the set time period. By means of the method, the body movement state of the monitored object is determined by detecting the pressure area and the pressure position of the leg pressure of the monitored object in the set time period, electronic elements such as a wearable sensor do not need to be used, cost is low, and normal activities of a monitored person are not affected.

A display apparatus includes a display section, a display control section, a distance detection section, and a coordinate detection section. The display section has a display area in which a selection image is displayed. When the selection image is formed by a plurality of images hierarchically associated with one another, the display control section displays consecutively the images configuring the selection image in accordance with the hierarchical association. The distance detection section detects a spatial distance between a pointer and the display area. The coordinate detection section detects coordinates which correspond to a position of the pointer. The display control section displays, together with a specified image displayed at a position corresponding to the coordinates detected by the coordinate detection section, related images in an immediately lower level in the hierarchy associated with the specified image, when the spatial distance detected is shorter than a preset threshold distance.
