Embodiment Construction

[0029] like figure 1 and figure 2 As shown, the digitized asphalt road recording device includes a degaussing head array 1, a writing head array 2, a verification head array 3, and a modification head array 4 arranged in parallel from front to back, each head array is installed on the vehicle chassis 6, and each head The height between the bottom of the array and the magnetized road surface is 1-10cm. The functions of the above four kinds of magnetic head arrays are as follows: the degaussing magnetic head array 1 eliminates the magnetized information existing in the magnetized road surface; the written magnetic head array 2 writes the magnetized information; The information is compared and verified; the modification head array 4 is operated according to the verification judgment of the previous verification head, if there is a difference in the data, write it again, otherwise it does not act.

[0030] Depend on figure 2 , 3 , 4, 5, it can be seen that the digital asphal...

Abstract

The invention provides a method and a device for recording digitalized asphalt road information. The device comprises an erasing magnetic head array, a write magnetic head array, a calibration magnetic head array and a modification magnetic head array which are sequentially arranged in parallel from front to back and connected with a singlechip respectively, wherein the singlechip is connected with a memory. The method comprises the following steps of: adding a magnetization material into asphalt on a normal road surface, so that the road has a data storage function; arranging a device for reading and writing road data on a universal vehicle chassis; and reading and writing data of a magnetic road surface of the road by magnetic heads, acquiring the written data through a magnetic induction sensor of the vehicle, and acquiring relevant inducing contents. A road inducing mode can be improved, the inducing precision is improved, a convenient and quick cruise mode is realized, and the read and write efficiency is relatively high.

Description

technical field [0001] The invention relates to a magnetic recording method, in particular to a digital asphalt road information recording method and a device thereof. Background technique [0002] A digital asphalt road method and its device is a brand-new method. At present, there is no concept of digital asphalt road on the road. The digital method of the road announces the data information of the vehicle through the road signboard and the LED display board, or through GPS navigation , or record information by magnetic track nails, such as 200620139223.7 (a magnetic road sign) and 201010200487.X (based on the magnetic positioning method of traffic vehicles with shifting cycle unique codes) disclose a magnetic road sign, which is used as a magnetic induction road sign by magnetic track nails , at equal intervals, without protruding the depth of the road surface, permanently buried on the road, with the above-mentioned group of magnetic track nails according to the S, N pol...
