An embodiment of the present invention provides a vehicle production control method, and referring to fig. 2, fig. 2 is a schematic flow chart of a first embodiment of the vehicle production control method according to the present invention.
In this embodiment, the vehicle production control method includes the steps of:
step S10: and acquiring vehicle-mounted code sheet information of semi-finished vehicles on the current vehicle production station.
It should be noted that the executing subject of the method of the present embodiment may be a vehicle production control device or a device with the same function, and the present embodiment and the following embodiments are described by taking the vehicle production control device as an example.
It is understood that the production station refers to the current position of the semi-finished vehicle on the production line, for example: the semi-finished product A is currently at the position corresponding to the No. 201 unit of the coating workshop, and the name of the coating workshop on the system is TZ, so that the corresponding current production station of the semi-finished product A can be marked as TZ 201.
The semi-finished product refers to an intermediate product that has been subjected to a certain production process and is qualified, but has not been finally manufactured into a finished product. The semi-finished products are divided into two kinds of self-made semi-finished products and outsourcing semi-finished products, namely 9 self-made semi-finished products, which are produced and processed by enterprises, are inspected to be qualified, delivered to a semi-finished product warehouse and need 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 the accounting system of the industrial enterprise, a 'self-made semi-finished product' subject is set to account the actual cost of the enterprise self-made semi-finished product. Such as pig iron and steel ingots produced by steel and iron combination enterprises, cotton yarn and grey cloth produced by textile printing and dyeing enterprises, and the like, belong to self-made semi-finished products. The homemade semi-finished products are generally processed in the enterprise, but can be sold for the outside. Generally, the cost of the semi-finished product is not calculated independently under the condition of single-piece and small-batch production, and is included in the product, and the cost of the semi-finished product is calculated only under the condition of large-batch production, so that the semi-finished vehicle refers to an automobile part which passes through a certain production process on a production line but is not finally assembled.
It can be understood that the vehicle-mounted code sheet is composed of a pry body number, a chassis number and an extensible identification bit, and the vehicle-mounted code sheet is similar to an identity information identification card which corresponds to a semi-finished product and can provide preorder production information, and the corresponding position of the vehicle semi-finished product in a production sequence can be checked through the chassis number.
The two-in-one vehicle is a semi-finished vehicle which needs to be subjected to off-line spot repair treatment due to the particularity of the quality of the produced vehicle body in a coating workshop, and the return vehicle is a semi-finished vehicle which needs to be subjected to re-spraying in a paint return line.
It can be understood that in the present embodiment, the loop returning vehicle needs to be directly communicated through the following steps: when the quality of the car body is abnormal, the car body needs to return to a paint spraying line for re-spraying from a modification line, returns to a color separation area 1 according to a process route, takes 30 minutes, belongs to a vehicle falling behind, writes a 03 identification position in the color separation area according to a return vehicle expansion function, enters a paint spraying chamber for re-spraying, is dried by a finish paint, arrives at a first floor, takes 50 minutes, arrives at an inlet 2 of a finish paint warehouse area, is interconnected by a conveying system of a machine transportation 9 area to obtain identification position information of the return vehicle, directly enters a modification line without entering the finish paint warehouse area according to a conventional method, saves 50 minutes (50 minutes for circulation in the finish paint warehouse area), passes through a qualified product area and a film pasting line, arrives at an inlet 5 of a PBS warehouse area of a second floor, is interconnected by a conveying system of a machine transportation area to obtain the identification of the return vehicle, directly walks along a special lane, saves 40 minutes, enters a coating line 6, and finishing the vehicle handing over for the next process (final assembly). Starting from a modification line, the process from a conventional process line to coating off-line needs 90 minutes (modification, qualification, 50 minutes of film pasting and 40 minutes of PBS (phosphate buffer solution) storage area), and under the condition that the condition is observed within 1 hour after the coating off-line, accumulating 150 minutes of 'influence can be influenced', and when a wire returning vehicle catches up: 30 (from the second floor color separation zone on the modification circuit) +50 (spray line) +50 (modification 20, qualified 15, film 15), and the "returning to the home" is effective in 140 minutes, and the compliance index is achieved.
In this embodiment, the following steps are required to perform spot two-vehicle catch-up: when the quality of the car body is abnormal and the car body is modified, the car body needs to enter a spot-repairing chamber 3, the maximum time of spot-repairing operation is 40 minutes, if the vehicle needs to be queued to enter a point supplement room (the number of the point supplement rooms is only 6, and 12-18 vehicles are needed when the number of the point supplement vehicles is large), waiting for 30-40 minutes, and after the point supplement is finished, writing a '02' identification bit in a point repair room area 4 according to a 'point two cars' extended function, interconnecting a machine transportation 9 area conveying system to obtain 'point two cars' identification information, entering qualified and film pasting (qualified 15 minutes and 15 minutes) without a routine, directly going to the second floor, saving 30 minutes, reaching a PBS (phosphate buffer solution) warehouse area entrance 5 of the second floor, interconnecting a machine transportation 10 area conveying system to obtain 'point two cars' identification information, entering a PBS warehouse area (40 minutes for circulation in the PBS warehouse area), directly walking a special lane, saving 40 minutes, entering a coating line 6, and finishing following a next procedure (general assembly) for vehicle transportation. Starting from entering a spot repair room, the process is carried out according to a conventional process route to a coating off-line, 70 minutes (qualified, 30 minutes of film pasting and 40 minutes of a PBS (phosphate buffer solution) storage area) is needed, the condition that the coating is observed within 1 hour after the off-line is considered, 130 minutes of ' influenceable effect ' is accumulated, and when two cars are spotted ' chased: and waiting for 40+ point compensation for 40 minutes, wherein the 'returning back' is effective and the compliance index is achieved.
It will be appreciated that the dot two-digit identification bit function extends 1, the extended Word06, occupies 2 characters, and the character "02" corresponds to the decimal: 12848, the chip data is spread as follows: word 00-Word 06, such as: 0100HZ34567802, a total of 7 words, loop car identification bit function extension 2, extension Word06, occupying 2 characters, the character "03" corresponding to decimal, 13104, and chip data extension: word 00-Word 06, such as: 0100HZ34567803, totaling 7 words, other chips are not identified as function extension, and the chip data are only Word00 to Word05, such as: 0100HZ345678, total 6 words, no conflict.
In specific implementation, the acquisition of the onboard code sheet information of the semi-finished vehicle at 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 AJ65BT-R2N, an EMS writer, an EMS code sheet (code carrying body), and a system working overview: the PLC system is a control center of the whole system, all on-site communication modules are connected in series through a CC-LINK bus, a code chip (code carrier) and a reader-writer are linked through RFID radio frequency, and then the RS232 is in communication connection with the CC-LINK through communication modules AJ65BT-R2N, so that the control LINK of the whole system is realized, and the functions of data acquisition, mapping, reading and writing and the like of the code carrier system are achieved;
step S20: reading the extension characters stored in the extension identification bits of the vehicle-mounted code sheet information according to a preset decoding rule, and judging whether the semi-finished vehicle needs to enter a 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 extension bit in the vehicle-mounted code slice 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 dot cars needing queue insertion, the characters of the two dot cars set by system initialization are 03 in the extended identification bits, and when the characters are written in through the decimal rule, the corresponding character bits are written in the extended identification bits of the corresponding semi-finished product A according to 03.
It can be understood that the extended identification bit is an identification bit which can be extended after the last bit of the chassis number in the vehicle-mounted code sheet, the identification bit occupies two characters, and the contents of 00-99 can be written according to the decimal reading and writing rule.
It should be noted that the characters refer to font-like units or symbols, including letters, numbers, operation symbols, punctuation marks and other symbols, as well as some functional symbols. Characters are the general names of letters, numbers and symbols in electronic computers or radio communications, which are the smallest data access unit in a data structure, and usually represent a character by 8 binary bits (one byte), and characters are the binary code form often used in computers and the information form most often used in computers.
In specific implementation, reading the extended characters stored in the extended identification bits of the vehicle-mounted code chip information according to a preset decoding rule is to decode the content corresponding to the extended characters by calling a decoding rule table of a background of a vehicle production control system and acquiring the rule decoding table.
In a specific implementation, the determining whether the semi-finished vehicle needs to enter the overtaking extension line according to the extension character is performed by comparing background data in the vehicle production control system, for example: at present, if the mark corresponding to the semi-finished product needing to be inserted is marked as 01 and the mark needing not to be overtaken is marked as 02, the background of the vehicle production control system can judge that the semi-finished product A needs to be inserted in the production process by reading the expansion mark bit of the corresponding vehicle-mounted code sheet of the semi-finished product A as 01.
Step S30: and if the semi-finished vehicle is judged to need to enter the overtaking extension line according to the extension characters, 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 extension line.
It should be noted that the overtaking mode signal is an execution request sent to the code-carrying system by the vehicle production control device after determining that the current semi-finished product needs to be subjected to queue control, and the execution request includes: the pry body 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.
