The automobile production line is a production line for producing automobile flow production. The automatic assembly device comprises welding, stamping, coating, a power assembly and the like, and can greatly improve the automation level of automobiles of some large companies in the production and assembly processes.
Along with the popularization of intelligent products, more and more electronic devices are gradually added in automobiles. In most of the automobile systems, the central control system, such as a CPU and a T-Box, controls the devices used to acquire the sensing information in the automobile in real time. In addition, the intelligent vehicle-mounted terminal CAN be directly communicated with a CAN bus of the automobile, and the CAN bus CAN be connected with each electronic device so as to acquire the state and the condition information of the automobile body. And uploading the parameters to the TSP background, or receiving the instruction sent by the background and returning the execution result. Moreover, the terminal and each electronic device have a certain communication protocol, and both the adaptability and the functionality need to be correspondingly configured.
At present, the automobile is produced by adopting the steps of assembly before testing. Each part or device required by the automobile is assembled on the automobile body, and then the central control system checks whether all devices can be controlled or not. Then, the traditional assembly and test are separated, and the hardware assembly and the software burn-in are also separated. When the central control is initialized, the device controlled by the central control is assembled on the vehicle body and is connected with the central control, for example, a wiper controlled by the central control, and after the assembly is finished, whether the wiper is in good function is detected through the central control. If control is not achieved, there are a number of problems that may exist. There are many possibilities of the hardware problem of the wiper itself, the hardware driving problem, the central control connection problem, and the matching degree problem of the central control. Moreover, in conventional production, the problematic components are usually removed from the vehicle and replaced with new ones. This will certainly increase unnecessary working time and cost.
