Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be described in further detail with reference to the accompanying drawings and specific embodiments. It should be noted that the embodiments and features of the embodiments in the present application may be arbitrarily combined with each other without conflict.
Example one
The embodiment of the disclosure provides a method for generating a dynamic traffic information code, which includes:
step 11, acquiring dynamic traffic information;
and step 12, generating a picture containing the dynamic traffic information code according to the acquired dynamic traffic information.
The dynamic traffic information code comprises different dynamic traffic information subcodes respectively generated according to different contents in the dynamic traffic information; different dynamic traffic information subcodes are distributed in different preset areas in the dynamic traffic information code;
the content in the dynamic traffic information comprises: position information, channel state information, channel course information and channel speed limit information. Namely, the correspondingly generated dynamic traffic information subcodes comprise: the position information subcode, the channel state information subcode, the channel course information subcode and the channel speed limit information subcode.
In some exemplary embodiments, the Dynamic Traffic Information (DTI) code is as shown in fig. 1. The DTI code comprises three large areas, namely a detection area with the middle 5 x 5, an information area, a free area at four peripheral edges and the like. Wherein the check area is located in the central area of the code, the part enclosed by the black frame will show black blocks, and the other part will show white blocks for checking the DTI code. The periphery of the inspection area is an information area, and the information area relates to the following information:
1) the position information is constituted by the site0, site1, and site2 regions, and corresponds to the position information of the X, Y, Z coordinate axis of the three-dimensional coordinate system. After 0 and 1 sequences are read from the codes, the current three-dimensional coordinate position can be obtained through a certain decryption and conversion process to decimal, and the actual position corresponding to the three-dimensional coordinate is searched in the system language, so that the position information of the DTI code display system and the position information of the current unmanned conveying equipment can be obtained. That is, the position information subcodes corresponding to the position information are distributed in the preset site0, site1, and site2 areas.
2) The channel state information is composed of state0 and state1 areas and describes the number density of unmanned conveying equipment on the corresponding actual channel, namely channel congestion conditions. After the information is processed by a certain function, a two-digit decimal number within 10 is obtained, 0-10 represents the congestion condition level of the channel, and the larger the number is, the worse the road condition of the channel is. After 0 and 1 sequences of state0 and state1 are obtained from the codes, the current channel road condition can be obtained after certain decryption, combination and decimal conversion, and the unmanned conveying equipment can determine whether to change the channel according to the set acceptable threshold and the emergency degree of the current task. That is, the channel state information subcodes corresponding to the channel state information are distributed in the preset state0 and state1 areas.
3) And the course information of the navigation channel consists of a direction area. The area information corresponds to the course of the navigation channel, and after the 0 and 1 sequences are read, certain decryption and decimal conversion are needed to obtain course information. Namely, the channel course information subcodes corresponding to the channel course information are distributed in the preset direction area.
4) The navigation channel speed limit information is composed of lim areas. The zone information is decrypted and converted after reading the 0 and 1 sequences to obtain a speed value, and the speed of all unmanned conveying equipment on the current channel needs to be lower than the speed value. Namely, the channel speed limit information subcodes corresponding to the channel speed limit information are distributed in the preset lim area.
The free areas are distributed with random codes, also called random filling information, as areas where the shadow 1 in fig. 1 is located, the corresponding coding results are called random filling information subcodes, and for the most common situations that the peripheral of the screen is worn and the resolution is not matched, which may occur in an electronic screen, the free areas distributed around in the DTI code can prevent the loss of effective information. Therefore, the free area can prevent the condition that the code is damaged or polluted, and then the data is lost, so that the code can not be read normally.
The calibration area, e.g. the middle 5 × 5 in fig. 1, distributes calibration information, and the coding result corresponding to the calibration information is also called calibration information subcode, and is used for the calibration of the DTI code.
In some exemplary embodiments, step 12 includes performing encryption conversion on the acquired dynamic traffic information (position information, channel state information, channel course information, and channel speed limit information) according to a certain rule, converting the data into a binary system, pre-complementing 0, respectively expanding the binary system to 10-bit numbers, placing the ciphertext into a subcode region corresponding to the DTI code, generating a binary check code (check information subcode) according to a preset check rule, placing the binary check code into the check region, and randomly setting the remaining regions (free region \ random filling information subcode) to 0 and 1 to generate the DTI code. For example, the DTI code shown in fig. 1 includes 13 × 13 color filling cells, and each color filling cell corresponds to a binary number in a one-bit subcode.
It can be seen that the DTI code shown in fig. 1 is a block diagram code, and is composed of a dynamic traffic information subcode, a check information subcode (check area), and a random padding information subcode (free area); wherein, the dynamic traffic information subcode includes: the position information subcode, the channel state information subcode, the channel course information subcode and the channel speed limit information subcode.
