Abstract

The invention discloses a portable CAN detection and upgrading device and method. The device comprises a microprocessor module, a CAN communication module, a USB communication module, an external power supply module, a storage module and an interaction module. The microprocessor module is connected with the CAN communication module so as to transmit and receive CAN messages. The microprocessor module is connected with the USB communication module so as to communicate with external USB equipment and receive an external power supply. The storage module is connected with the microprocessor moduleto store data. The external power supply module is connected with the microprocessor module so as to supply power to external CAN equipment. The interaction module is connected with the microprocessor module so as to send a control instruction and display a processing result. According to the invention, the CAN message can be analyzed in real time and the CAN fault can be judged under the condition that a PC is not carried, and meanwhile, the external CAN equipment can be upgraded without carrying a PC, and power supplies with different voltages are provided for the external CAN equipment.

Description

technical field [0001] The invention relates to the field of vehicle technology, in particular to a portable CAN detection and upgrading device and method. Background technique [0002] At present, there are many types of CAN cards on the market, but the functions are basically the same or similar. The mainstream products are CAN cards that convert bus signals into USB signals and connect to PCs. In this use, a PC must be used to operate together, and the technical requirements for the operator are relatively high, and equipment such as a portable computer must be carried every time. [0003] In addition, at present, for product upgrades of non-networked terminal devices, special programming tools are used to upgrade products. However, many products now do not reserve upgrade interfaces due to factors such as appearance, use environment, and design, and can only be upgraded by disassembling the product. Contents of the invention [0004] The main purpose of the present i...
