0 Introduction As we all know, the auto 4S shop has a car franchise model with the core of “sale” (Sale), spare parts sales (Spare Part), after-sales service (Service), and information feedback (Survey). With the change of consumers' consumption concept and the improvement of consumption level in China, when purchasing a car, in addition to considering the price requirements, the after-sales service should also be in line with the car powers such as Europe, Japan and the United States. At present, the auto 4S shop wants to break through the limitations of the manufacturer, and to create its own brand image must make a fuss in the after-sales service of the car, to customer-centered, to show customers the quality after-sales service and professional technical level, so that customers can always feel at ease, Intimate and humanized service; establish and improve customer relationship management system, pay attention to information feedback and communication with customers, enable sales customers to be transformed into after-sales customers in a timely manner, and provide timely and effective “one-on-one” service to customers, and gradually Achieve two or even multiple marketing.
At present, 4S shop business usually includes: new car listing and release, multi-brand consignment, used car certification and trading, new car licensing agency, auto insurance business agent, car rescue, auto parts sales, car maintenance, car repair, car loan, vehicle report More than a dozen businesses, such as insurance and clubs. In the profit system of 4S shop, the whole vehicle sales, accessories and maintenance are three-point world, especially the maintenance service has become the main source of profit for the 4S shop. In view of the current service status of domestic auto 4S stores, the auto 4S shop intelligent management system has been tailored for domestic auto 4S stores.

1 License plate recognition system Vehicle license plate automatic identification technology is an important part of intelligent transportation system. It has a wide range of applications in video surveillance such as intelligent transportation and electronic police. At present, the license plate recognition system is mainly used in the following areas: “Electronic Police” for safe city control, traffic intersections, community vehicle management system, parking lot entrance management system, and highway speed camera. The license plate recognition system can capture the license plate of a vehicle traveling in the identification area through intelligent recognition technology, then accurately locate the license plate image from the video area, and then divide and recognize the characters, and finally integrate the character information and output to the designated The server or database provides basic information for applications in each of these areas.
A license plate recognition system based on image processing usually consists of five parts:

3 Conclusion The license plate recognition system is in the development stage both at home and abroad. The license plates and actual traffic environment of different countries in the world are also different, so it is difficult to introduce and promote. However, although some products developed by the company have achieved practical application in the domestic security field, the application of the license plate recognition system and the customer relationship management system of the 4S shop is less, and in most cases, it is two relatively independent systems, which is not conducive to information. shared. This paper starts from the actual needs of the project, through the information transfer between the license plate recognition system interface and the server middleware, and then shares the data with the customer relationship management system to provide customized applications for each terminal. This program is an integrated design for the call center and license plate recognition of the 4S shop of the automobile, and is an innovative research in this field.
