Magnetic asphalt road data pumping vehicle and pumping method

Abstract

The invention provides a digital asphalt road data pumping vehicle comprising an automobile, wherein the automobile is sequentially provided with a degaussing wheel, a write-in wheel, a checking wheel and a modifying wheel in parallel from front to back; four rows of wheels are respectively and externally sleeved with silicon steel sheet outer wheels; the structures of the four rows of the wheels are the same and fixing shafts are arranged at the centers of the wheels; the fixing shafts are connected with a driven gear through a bearing and the driven gear is connected with a driving wheel; the degaussing wheel is internally provided with a degaussing magnetic head array, the write-in wheel is internally provided with a write-in magnetic head array, the checking wheel is internally provided with a checking magnetic head array and the modifying wheel is internally provided with a modifying magnetic head array; the array quantity of each magnetic head array is the same as the quantity of a road magnetic channel; and the automobile is internally provided with a read-write degaussing control system and the driving gear is driven by a driving circuit. By utilizing the vehicle to carry out data pumping on a magnetized road surface, four steps of degaussing, writing in, checking and modifying are carried out, so that the magnetized road surface can be accurately and efficiently read and written, degaussed and the like.

Description

technical field [0001] The patent of the present invention relates to a magnetic recording method, in particular to a digital asphalt road data filling vehicle and a filling method. Background technique [0002] A digital asphalt road data injection method and its device are a brand-new method. At present, there is no concept of digital asphalt roads in highways. The digital method of roads announces the data information of vehicles through road signs and LED display boards, or Through GPS navigation, the system reads and writes through magnetic system data, which can improve the road guidance method and improve the guidance accuracy. It is a convenient and fast cruising method, which improves the writing speed and efficiency. [0003] At present, it is often used in media recording equipment, such as patent 200410001398.7 (system and method for determining the writing track width of a magnetic tape head), the writing track width of the magnetic tape head of this patent is o...

Problems solved by technology

At present, there is no concept of digital asphalt roads on highways. In the early days, people developed the digitalization method of magnetic track nails, such as patent 200610019775.9, two-dimensional magnetic sensor for magnetic track nail positioning and navigation. Numbers are represented by the direction of the north and south poles of the magnetic track nail. This method requires a lot of manpower and material resources to rewrite
