• Ensure the timely supply of raw materials;
• Transmit real-time status detection data;
• Monitor the status of production line equipment to reduce the probability of deviation in the production process;
• Perform quality control and real-time observation to reduce the repair rate;
• Transmit production and assembly instructions to improve the flexibility and accuracy of the production line;
• Track the production cycle of products to reduce losses;
• Establish a product quality tracking database;
Customer trouble:
China’s manufacturing industry (such as automobiles) has a clear gap with the international market in terms of management level, manufacturing capacity, quality, and price. The new products are characterized by the continuous shortening of product life cycles, increasingly personalized customer needs, and higher and higher quality requirements. The market situation in China also poses new challenges to China’s automobile manufacturing industry.
• Document delivery lag
• Loss in manual delivery of documents
• Residual data in the EAM system cannot be processed in time
• Engineers repeatedly input data
• Data handwriting and input errors

Production monitoring scheduling management solutions
The production scheduling instructions between working procedures are mostly the use of electronic billboards E-KANBAN for information reading and conversion. E-KANBAN is an information card with electronic bar code technology as the carrier; the electronic billboard of the translation car or workshop is an LED or LCD electronic display, which mainly achieves two purposes:
• Realize JIT on-time collaboration of materials, personnel, and vehicles;
• Realize the on-demand transmission of production scheduling instructions;
When the operator of the painting and undertaking production line starts a certain process, use the MT02 industrial-grade mobile data terminal to scan the vehicle information card and the process bar code of the process. The MT02 industrial-grade mobile data terminal will automatically review the order according to the order data. The start-up time information is transmitted to the back-end dispatch center database in real time; the process barcode is also scanned after completion, and the completion information is transmitted to the back-end database.
At the same time, the time information required for the last process is communicated to the operators who need to cooperate in the subsequent process through the industrial-grade mobile data terminal, and input or output in the form of production instructions. At the same time, the system can also calculate a certain value by using the automatic accumulation function of the system. The completion amount and efficiency of the process in a certain time.
The workshop scheduling logic model is briefly described as follows:
• The data acquisition subsystem performs real-time data tracking on the status information of the actual workstations on the production site;
• Data analysis by the dispatching center, calculation of the operating efficiency, operating mode, and automatic reminder of the operator’s tasks for each station;
• The specific content of the work station, the processing schedule, the material conversion and allocation of the entire workshop, etc., if necessary, apply APS for re-trial planning and issue new production instructions.
• Involving two production modes of business linear work and non-linear work, the linear, non-linear, and cross-mixed modes will be used for data calculation and analysis, and the goal of increasing production capacity has been achieved.
• Software platform data interaction: production site data acquisition subsystem
Pre-preparation for data collection at the production site:
• 802.11b/g wireless network communication environment is deployed in painting, undertaking and trial delivery workshops
• The paint shop is equipped with mobile data collection terminals according to each process (about 25, or according to shifts/quality inspection, and the balance of quantity and convenience should be considered). Small areas are concentrated and equipped with mobile data collection terminals and process kanbans, and the quality is abnormal. Information board
• Each driver in the trial workshop is equipped with a mobile terminal, which accepts task instructions in real time and feeds back the working status
• Barcode corresponds to standardized process and quality information one by one
• LED electronic billboards are placed above the shifting vehicle lane and the material supply workshop, which scrolls in real time to display 5-8 process vehicle numbers and material supply instructions that are the first to be completed and to be shipped
Data collection operation process
• When the process starts, the shift leader scans the corresponding process barcode and automatically records the start time
• Scan the corresponding barcode at the end of the process, and automatically record the end time
• When abnormal quality problems occur between processes, the shift leader or quality inspector scans the corresponding quality information bar code, and automatically records the process delay time
• Scan the barcode and transmit it to the production monitoring and dispatching center in real time via wireless network
• The process status information is fed back to the APS scheduling system in real time, and the schedule is automatically adjusted or recalculated
• Process status information and production instructions are notified in real time through electronic billboards, mobile data terminals, etc. to the next or need to collaborate with process personnel
Defect management
The whole vehicle production is mainly assembled and involves a large number of parts (including in-house self-made parts and outsourced parts). Various defects will inevitably occur during the assembly process. Some of them come from parts, some are produced in this process, and some are produced in the previous process. of. In order to improve the quality and reduce the repair rate, it is necessary to monitor and record the defects of each car in real time, and take timely measures.
