In the foreign automobile manufacturing industry, the application of radio frequency identification (RFID) systems is relatively common. The following uses the cases of Taiwan Yulon and the US EMS company to introduce solutions for the application of RFID products in the automobile industry.
The old-fashioned manufacturing information acquisition cards and data acquisition systems of the modern automobile manufacturing industry lack real-time performance. The decision-making, production, inventory management and financial systems of automobile companies require real-time online engineering monitoring. The old-fashioned information card only contains product manufacturing information required by assembly technicians at a certain station. The system does not have the ability to quickly obtain real-time data tracking capabilities such as manufacturing information, item location, problem and failure analysis, so cars on the production line will not move faster than the written plan, and the inventory will be adjusted before leaving the factory due to manual processing of the work plan. With a backlog of 3 days in the product distribution field, this information tracking method is very slow, error-prone, and lacks the ability to provide forward-looking plans for future product production. Companies in the automotive industry will realize that what they need is an automated tracking system that can collect data from the beginning of each car to different production processes and along the distribution channels across the country.
After analyzing and inspecting all available automated tracking systems, automotive customers believe that RFID (radio frequency identification) systems can meet the indicators they require. RFID products can provide tracking capabilities (such as barcodes) that other systems cannot achieve, and can be used normally in the harsh environment of automobile manufacturing, such as dust, oil, and high temperature. In addition, the RFID tag does not require the straight line visibility of the barcode, which allows the RFID tag to be flexibly placed in different locations to provide different solutions.
Companies that are the first to adopt “automated identification systems” and new radio frequency identification technology will greatly improve the efficiency of the supply chain and enable these companies to surpass their competitors. It can reduce the amount of safety stock by 10% to 30% to reduce storage costs.
The harsh requirements of the industrial environment also make RFID the best choice. Some environments require data collection systems to operate normally in liquids, chemicals, dust, and high-temperature environments. RFID can even be used in a production environment with a high temperature of 240 degrees Celsius. With RFID, RFID tags do not have to be within the optical visible range of the reading head. RFID tags have the ability to penetrate most non-metallic materials, so they can be embedded in carriers, containers, and even products. Moreover, these containers and products can be sealed in the outer packaging, which does not adversely affect the results of data collection.
In addition to the application of the automotive industry in the licensing process, RFID technology will also play a greater role in the entire traffic management field. It can be used to record and process various main and auxiliary information in highway traffic management. Its main applications include: high-grade highway non-stop toll, road maintenance fee payment, passenger and truck operation management, traffic flow monitoring, electronic tickets, driving licenses, handling of violations of traffic regulations, border crossing inspections, vehicle information and maintenance records, driving dynamic parameter records (automobiles) Black box), car electronic keys (car door opening and closing and ignition control, etc.), car monitoring, alarm data recording, accident rescue information processing.
Basic application model and hardware equipment for managing product data with RFID
Current status of the automobile manufacturing industry and improvement opportunities
At present, most of the manufacturing and sales management of my country’s automobile industry continue to use the old management model, whether in storage management or sales management, restricting the development and take-off of the automobile industry!
In the traditional management mode of the automobile industry, paper receipts and manual management are the mainstream methods. This method brings poor data reliability, low operating efficiency, difficult statistical analysis, and extremely small possibility of extracting useful information for the enterprise! This traditional management model can no longer adapt to the development trend of today’s auto companies, especially the advent of the information age. How to use advanced management models to enhance competitiveness and to meet the information revolution is very realistic and important for people in the auto industry. The problem.
Today’s automobile industry has the following characteristics:
●The automobile production volume is increasing day by day
With the improvement of people’s consumption level, the automobile market will become larger and larger, and the output of automobile production will also increase substantially. Increasing output, followed by logistics and information flow, have correspondingly increased the management difficulty of enterprises, and the management efficiency of traditional management models will be greatly reduced, so that both the efficiency and accuracy of decision-making Sexually will encounter unprecedented challenges.
●The automotive industry is highly mobile
Today, the corporate market is the global market, and cross-regional and cross-border sales have gradually become the mainstream of sales, and the automotive industry is no exception. Therefore, the fluidity from parts to finished products will also be greatly enhanced in terms of time span, geographical span, etc. How to use fluidity to reduce costs and improve quality, this must be reformed in management methods, especially in logistics and information flow management. , A new management model based on RFID to manage product data provides a good solution for these problems.
●Multiple distribution channels
The market is getting bigger and bigger, and there are more and more sales channels for the company’s agents. How to manage these sales channels is not only a big issue about sales, but also about the company’s image, product services, etc., dealing with users. The field has a major impact, if the management is not good, a big cake will bring a big disaster! Especially at the current level of consumption in China, automobile consumption is a very important matter. How to manage sales agents so that they can add value to the company in terms of corporate image and product services is a major issue.
●User information is scattered
“Our users are all over the world!” This is the dream goal of every enterprise. More and more users are very gratifying. However, if one user is ignored, hundreds of users may be lost! Good management of users is the guarantee of our output! Obviously, user management combined with production, supply and marketing is the correct way to manage users! The new management model based on RFID to manage product data is a red line that integrates the production, supply and marketing of the enterprise, and it is an excellent opportunity to establish a new corporate image and meet the challenges of the new century!
There are many characteristics of the automobile industry, and it also brings many problems. The analysis or investigation must be based on the customer information and the automobile information. The information collection plan for these aspects is the premise of the enterprise market analysis.
How can we quickly and effectively obtain the detailed information of customers, and how to get the information of car sales immediately, the following is an example of the application of RFID in the automotive industry to manage product data:
RFID management product data has the following characteristics: high efficiency, accuracy, anti-counterfeiting, independence, large capacity, variable substrate…… It can reform the traditional management mode of enterprises from the perspective of logistics and information flow, and it happens to be solved at low cost. The above problems have led to the progress and development of all aspects of auto companies.
If the automobile industry adopts RFID to manage product data, it can not only solve the problems of raw material procurement, inventory management, and sales management, but also greatly improve efficiency and accuracy. At the same time, problems such as after-sales service and quality tracking will be solved, and corporate image and corporate profits will also be solved. It will be a big step.
1. Save management costs by 40%
● Save manpower
● Reduce error rate
● Reduce material consumption

RFID after-sales service development strategy
The work items of the automotive industry to implement electronic tags: the test process and the items that passed the test
Reality:
RFID technology is used to realize automatic control and monitoring on the production line, increase productivity, improve production methods, and save costs. The German BMW Motor Company applies radio frequency cards on the assembly line to produce as many customized cars as possible. The production of BMW cars is based on the requirements styles put forward by users: users can select the color, engine model and tire style of the car they need from tens of thousands of internal and external options. In this way, the car assembly Hundreds of styles of BMW cars have to be assembled on the assembly line. Without a highly organized and complex control system, it is difficult to accomplish such a complex task. The RFID system configured by BMW on its assembly line uses a reusable radio frequency card, which can carry all the requirements of the car in detail, and has a reader at each work point, so that it can Ensure that the car can complete the assembly task without error at each assembly line position.
The assembly workshop of Shanghai General Motors is the place where people can feel the role of RFID technology on the production line most. Standing in a place of the visitor and looking down, the production line in front of you is the blue GL8, followed by The flaming GS is followed by a purple Sail. It automatically arranges vehicle production plans based on the individual needs of customers from the marketing department. In addition to the customer’s personalized requirements for models and configurations, stored in the computer, there is also the SGM production number of the car. This number can be called the ID number of the vehicle on the assembly line. The No. 1 read-write station of the automatic body recognition system automatically reads the manufacturing information into the electronic tag (RFID), and the manufacturing information follows the body through each production section until it enters the assembly workshop. In this way, through the computer networking system, the “ID Card Number” and the customer’s personalized needs are uniquely transmitted to each station. The machine performs different tasks without error according to the different production numbers of the vehicles, and the workers beside the line correctly complete different assembly tasks according to the manufacturing information labels that are pasted on the left side of the car body and correspond to the production numbers.
