It is understood that the production station refers to the current position of the semi-finished vehicle on the production line, for example: the corresponding current production station of the semi-finished product A can be recorded as TZ201 when the semi-finished product A is currently at the corresponding position of the 201 st machine set of the coating workshop and the systematic naming of the coating workshop is TZ.
The semi-finished product refers to an intermediate product which has undergone a certain production process and is checked to be qualified, but has not been finally manufactured into a finished product. The semi-finished products are divided into two self-made semi-finished products and outsourcing semi-finished products, namely, the self-made semi-finished products are produced and processed by enterprises, are inspected to be qualified, and are delivered to a semi-finished product warehouse and are required to be processed continuously; the outsourced semi-finished product is a semi-finished product purchased from the outside and is treated as a raw material. In an industrial enterprise accounting system, a homemade semi-finished product subject is set to account for the actual cost of the homemade semi-finished product of the enterprise. For example, pig iron and steel ingots produced by a steel united enterprise, cotton yarns and grey cloths produced by a textile printing and dyeing enterprise and the like belong to self-made semi-finished products. The self-made semi-finished product is usually processed continuously in the enterprise, but can be sold outside.

The second vehicle is a semi-finished vehicle that needs to be subjected to the spot repair treatment offline in a painting shop due to the specificity of the quality of the vehicle body, and the return vehicle is a semi-finished vehicle that needs to be subjected to the re-spraying of the paint return line.
It can be understood that in this embodiment, the following steps are needed to be performed for the straight-through of the loop wheel machine: when the quality of the automobile body is abnormal, the automobile body needs to be returned from the finishing line to the paint spraying line for re-spraying, the automobile body returns to the color separation area 1 according to the process route for 30 minutes, the '03' mark position is written in the color separation area according to the 'loop car' expansion function, the automobile body is sprayed again in the paint spraying room, after the finishing paint is dried, the automobile body reaches the entrance 2 of the finishing paint warehouse after 50 minutes, the conveying system of the mechanical 9 area is interconnected to obtain the 'loop car' mark position information, the automobile body does not enter the finishing paint warehouse conventionally, is directly communicated to the finishing paint line, saves 50 minutes (50 minutes for circulation in the finishing paint warehouse), and enters the PBS warehouse after passing through the combining area and the film pasting line, the conveying system of the mechanical 10 area is interconnected to obtain the 'loop car' mark as information, the automobile body does not enter the PBS warehouse conventionally (40 minutes for circulation), the special road is directly moved, 40 minutes is saved, the finishing the coating and the following procedure (final assembly) is completed. Starting from the finishing line, 90 minutes (finishing, qualification, film pasting for 50 minutes and PBS reservoir area for 40 minutes) are needed from the finishing line to the coating off line according to the conventional process, and taking the condition of adherence within 1 hour after the coating off line into consideration, the total of 150 minutes which can be influenced and the following of the following line is considered, wherein the following time is as follows: 30 (from the second floor color division area on the finishing loop) +50 (paint line) +50 (finishing 20, qualification 15, film 15) for 140 minutes, the "team" is effective, and the compliance index is met.
In this embodiment, the following steps are needed to be performed for the two-car catch-up: when the quality of the vehicle body is abnormal, the vehicle body needs to enter a spot repair room 3 until the vehicle body is modified, the spot repair operation time is 40 minutes at the maximum, if the vehicle body needs to be queued to enter the spot repair room (only 6 spot repair rooms are needed, 12-18 spot repair vehicles are needed when the vehicle body is more), after the vehicle body is completed, a '02' mark position is written in a spot repair room area 4 according to a 'spot two-vehicle' expansion function, a conveying system in a machine transport 9 area is interconnected to obtain 'spot two-vehicle' mark information, the vehicle body does not enter a qualified and film-adhered (qualified 15 and film-adhered 15 minutes) conventionally, the vehicle body is directly connected to a second floor, 30 minutes is saved, the vehicle body enters a PBS (PBS) warehouse area entrance 5, the conveying system in a machine transport 10 area is interconnected to obtain 'spot two-vehicle' mark information, the vehicle body does not enter the PBS warehouse area conventionally (40 minutes when the vehicle is circulated), the vehicle body is directly tracked, 40 minutes is saved, the vehicle body enters a coating line 6, and the vehicle delivery process (assembly) is completed. From entering the spot repair chamber, according to the conventional process line to the coating offline, 70 minutes (qualified, film pasting 30 minutes, PBS reservoir 40 minutes) are required, and taking the condition of adherence within 1 hour after the coating offline into consideration, 130 minutes of 'can be influenced' are accumulated, and when 'two-in-two' catch-up: wait for 40+ to supplement 40 for 80 minutes, and "return to team" is effective, meeting compliance criteria.
It can be understood that the two-digit identification bit function is extended by 1, the extended Word06 occupies 2 characters, and the character "02" corresponds to decimal: 12848, the chip data is expanded as follows: word00 to Word06, such as: 0100HZ34567802, 7 words in total, loop vehicle identification bit function expansion 2, expansion Word06, occupying 2 characters, wherein character '03' corresponds to decimal, 13104, and the chip data expansion is as follows: word00 to Word06, such as: 0100HZ34567803, 7 words total, and the other not identified as functionally extended, the chip data is only Word00 to Word05, such as: 0100HZ345678, a total of 6 words, no collision.
In specific implementation, the acquisition of the on-vehicle chip information of the semi-finished vehicle on the current vehicle production station is realized through a code carrying system configuration framework, wherein the PLC system is Mitsubishi Q26UDEHCPU, the communication module is an AJ65BT-R2N, EMS writer, EMS chips (code carrying bodies) and the system work overview: the PLC system is a control center of the whole system, all communication modules on site are connected in series through a CC-LINK bus, a chip (code carrier) and a reader-writer are connected through an RFID radio frequency LINK, and RS232 is connected with the CC-LINK through communication modules AJ65BT-R2N in a communication manner, so that the control LINK of the whole system is realized, and the functions of data acquisition, mapping, reading and writing of the code carrier system are achieved;
step S20: and reading the extension characters stored in the extension identification bits of the on-vehicle chip information according to a preset decoding rule, and judging whether the semi-finished vehicle needs to enter an overtaking extension line or not according to the extension characters.
It should be noted that, the preset decoding rule is a fixed encoding rule set by the system, and the read-write operation can be performed on the extended bits in the on-vehicle chip information through the preset decoding rule, for example: when the preset decoding rule is a decimal rule, a certain semi-finished product A belongs to two points to be inserted, the character of the two points set by the system initialization in the expansion identification bit is 03, and when writing is carried out through the decimal rule, the corresponding character bit is written into the expansion identification bit of the corresponding semi-finished product A according to the 03.
It can be understood that the extended identification bit is an expandable identification bit after the last bit of the chassis number in the onboard chip, the identification bit occupies two characters, and the content of 00-99 can be written according to the decimal read-write rule.
The character refers to a font unit or symbol, including letters, numbers, operation symbols, punctuation marks and other symbols, and some functional symbols. Characters are the collective names of letters, numbers, and symbols in an electronic computer or radio communication, which are the smallest data access units in a data structure, and one character is usually represented by 8 binary bits (one byte), and the characters are binary coding forms frequently used in a computer, and are also the most commonly used information forms in a computer.
In specific implementation, the extended characters stored in the extended identification bits of the on-vehicle chip information are read according to a preset decoding rule, and the content corresponding to the extended characters is decoded by calling a decoding rule table of a background of a vehicle production control system and obtaining the rule decoding table.
In a specific implementation, the determining whether the semi-finished vehicle needs to enter the overtaking expansion line according to the expansion character is by comparing background data of the vehicle production control system, for example: the background of the vehicle production control system currently prescribes that if the mark corresponding to the semi-finished product needing to be subjected to the queue insertion is marked as 01 and overtaking is not required to be performed as 02, the semi-finished product A can be judged to be subjected to the queue insertion in the production process by reading the expansion mark bit of the corresponding on-vehicle chip of the semi-finished product A as 01.
Step S30: and if the semi-finished vehicle is judged to enter the overtaking expansion line according to the expansion character, outputting an overtaking mode signal to a code carrying system so that the code carrying system controls the semi-finished vehicle to enter the overtaking expansion line.
The overtaking mode signal is an execution request sent to the code carrier system after the vehicle production control device determines that the current semi-finished product needs to be subjected to the queue insertion control, and the content of the execution request includes: and the skid number of the semi-finished product, the current specific production station of the semi-finished product, and the position of the target queue of the semi-finished product.
It can be understood that the overtaking expansion line is a production line special for performing team insertion, a semi-finished product to be overtaken intelligently exists in the overtaking expansion line, and the overtaking expansion line is a special chasing channel, so that a flexible and automatic manufactured special channel is realized.

Further, in order to reduce the failure rate of the semi-finished product overtaking, if it is determined that the semi-finished product vehicle needs to enter the overtaking expansion line according to the expansion character, an overtaking mode signal is output to a code carrier system, so that after the step of controlling the semi-finished product vehicle to enter the overtaking expansion line by the code carrier system, the method further includes: after the semi-finished vehicle comes off line from the overtaking expansion, moving the semi-finished vehicle to a target production station; acquiring vehicle-mounted code information of adjacent semi-finished vehicles in the target production station; judging whether overtaking is successful or not according to the vehicle-mounted code information of the semi-finished vehicle and the vehicle-mounted code information of the adjacent semi-finished vehicle; and after judging that the overtaking failure of the semi-finished vehicle occurs, sending judging information to the code carrier system so that the code carrier system recovers the semi-finished vehicle.
