Method and device for remote upgrading of vehicle-mounted electronic device

Abstract

The invention discloses a method for remote upgrading of a vehicle-mounted electronic device. The method comprise the following steps: steps 1, upgraded firmware files are uploaded into a specific file folder of a specified FTP server, and relevant parameters of the FTP server are set when the vehicle-mounted electronic device is initialized; steps 2, a host computer of the vehicle-mounted electronic device is informed to execute upgrading commands, so as to enter an FTP upgrading mode; step 3, the host computer of the vehicle-mounted electronic device starts an FTP (File Transfer Protocol) stack to log in the FTP server, a relevant file holder is searched, and specified upgraded files are found out in the file holder; step 4, the host computer of the vehicle-mounted electronic device automatically executes file download, and the downloaded files are stored in a specified storer of the vehicle-mounted electronic device; and step 5, the host computer of the vehicle-mounted electronic device starts a BOOT program, an IAP (Internet Access Provider) program runs, upgraded files downloaded from the FTP server are upgraded and burnt, and after burning, a latest program runs, and upgrading process is accomplished. The remote upgrading method is simple to operate, does not affect the normal running of a vehicle, and greatly reduces maintenance and operation costs.

Description

technical field [0001] The invention relates to the field of electronic technology, in particular to a remote upgrade method and device for vehicle-mounted electronic devices. Background technique [0002] In recent years, with the rapid development of our country's economy, the automobile industry has made rapid progress, and automobiles have been used more and more widely as an ideal modern means of transportation. GPRS is the abbreviation of General Packet Radio Service. The general wireless packet service is a wireless packet switching technology based on the GSM system, providing end-to-end, wide-area wireless IP connections. GPRS is different from the previous method of continuous channel transmission. It transmits in groups. Therefore, the cost borne by the user is calculated by the unit of the transmitted data instead of using the entire channel. Relatively speaking, the cost is relatively cheap. Because GPRS has the advantages of large transmission capacity, stron...

Problems solved by technology

However, with regard to the upgrade methods of these electronic devices after leaving the factory, there are mainly two solutions now, one is: recall these electronic devices after leaving the factory to the factory, and perform corresponding upgrade processing; but since these electronic devices have already reached the hands of consumers , the recall and upgrade of these electronic devices will definitely lead to dissatisfaction among users; and because the distribution of products has become very scattered at this time, not to mention that the vehicles are moving, therefore, it is impossible to call in large quantities in a short time. Unified upgrade processing will inevitably cause a lot of economic losses to the enterprise, and at the same time, the corporate image will be greatly reduced in the hearts of consumers

The second is: sending professional programming personnel to use professional programming equipment to upgrade these electronic devices after leaving the factory; this solution has higher professional requirements for operators and requires a lot of manpower and material resources. less practical
