Description
Technical Field
The invention relates to a multifunctional electric vehicle alternating-current charging pile, belongs to the technical field of electric vehicle charging, and particularly relates to the technical field of road image information acquisition of automatic driving and unmanned electric vehicles.
Background
The driving motor of the electric automobile has the function of converting the electric energy of a power supply into mechanical energy and directly driving wheels and a working device through a transmission device. The charging pile is a main means for supplementing driving energy of the electric automobile.
The charging pile has the function similar to that of an oiling machine in a gas station, can be fixed on the ground or a wall, is installed in public buildings (public buildings, malls, public parking lots and the like) and residential community parking lots or charging stations, and can charge electric automobiles of various types according to different voltage levels. The input end of the charging pile is directly connected with an alternating current power grid, and the output end of the charging pile is provided with a charging plug for charging the electric automobile.
The function of traditional fills electric pile is single relatively, mainly has: 1) Charging control (electric leakage, stake car answering); 2) Protection at the grid end (lightning protection, overvoltage, overcurrent); 3) Information reporting (optional), etc.; the electric pile is a function of a typical charging pile, the electric pile is safely used for an electric automobile, and the internet problem to be solved is that a user finds the pile, pays by a code scanning or other means and then charges. I.e. the use of charging piles is limited only to the conventional power supply of conventional electric vehicles. With the development of automobile technology, advanced auxiliary driving and unmanned technology are continuously perfected, but with the development, higher requirements are also provided for obtaining accurate road information, however, in the prior art, no charging pile system or device matched with automatic driving road accurate information obtaining technology has been found.
For an automatic driving automobile, various sensors such as a radar, a camera and the like are eyes of the automobile, and accurate information of a road is continuously acquired. In these "eyes", the camera is relatively simple. Its advantages are high effect: the precision is high, the distance is long, and the method is visual and convenient; however, the disadvantages are also highlighted: is greatly affected by weather, such as haze, large-scale rain and snow weather, and the like. However, the conventional vehicle radar has various defects, although the conventional vehicle radar has higher real-time performance, accuracy and reliability than the ultrasonic detector and the computer vision equipment. Currently, the main research is focused on millimeter wave radars and lidars. The most commonly used conventional radar is millimeter wave radar, but even so, the characteristics of low precision and short visible range still exist. These two drawbacks are placed in autopilot, but are very prone to accidents. For example, a millimeter wave radar can find roadside obstacle, but only "see" the blurred body, while a centimeter level precision laser radar can clearly distinguish whether the obstacle is a road shoulder or a slope in a very short time, and if an automatic driving automobile judges that the obstacle is a slope, a decision of safely driving the vehicle can be made. However, the lidar has the disadvantages of high cost and being unable to work around the clock, i.e. poor effect in extreme weather such as rain, snow, haze, etc.
Quantum imaging is an important branch of quantum optics, and is a problem of studying the optical imaging limit achievable under the quantum characteristics of light fields. Unlike classical imaging, quantum imaging develops new optical imaging and quantum information parallel processing technology on the quantum level by utilizing the quantum mechanical property and intrinsic parallel characteristics of a light field. In contrast to the conventional optical imaging technique, which acquires image information of a target by recording the light intensity distribution of a radiation field, quantum imaging obtains an image of an object by utilizing, controlling (or simulating) the quantum fluctuation of the radiation field. As a novel imaging technology, the implementation of entangled light source associated imaging in quantum imaging makes it possible to transfer object image information of one of two mutually independent spaces, thereby implementing imaging. Thermal light sources can also achieve correlated imaging. Compared to classical imaging, quantum imaging has the following advantages: 1) Super-resolution imaging-imaging resolution in quantum imaging can break through the resolution limit of Li Yanshe; 2) Quantum imaging is single-pixel imaging, i.e., it is possible to use quantum imaging for imaging purposes when a bulky face detector is unsuitable or cannot be employed; 3) Detection and imaging separation in quantum imaging can overcome the defect of poor anti-interference capability of classical imaging. The mid-term project evaluation report in 2012 by Shanghai ray apparatus shows that a target which cannot be taken by a common optical telescope of 420mm can be taken in a severe environment by using a quantum imaging camera with the caliber of only 18 mm. In 2013, the project group carries out a large number of outdoor remote sensing imaging experiments under typical meteorological conditions such as sunny, night, cloud, rain and fog for the first time internationally. The experiment realizes the intensity-related imaging with the resolution of 1cm and over 2 times of the super diffraction limit resolution on the field one kilometer level detection distance.
The quantum imaging technology is not influenced by the shielding of haze, rain, snow and the like, but has high cost and general dynamic performance, and is not suitable for being mounted on a vehicle which is easy to jolt.
