The necessity of CAN equipment upgrade

The reason why the CAN bus was able to overcome many competitors and became the most mainstream automotive control bus at that time is because its data transmission speed is relatively fast, the bus bandwidth is large (compared to other buses of the year), and the data transmission distance is long. There are many devices connected to the node, and it also has good anti-interference ability. No matter from which point of view, CAN bus is a bus that is very suitable for application in automobile control. However, as stated at the beginning of our article, modern cars have integrated more and more electronic devices that require bus bandwidth, such as GPS navigators, etc., then the CAN bus is a bit unsightly. After all, the theoretical maximum baud rate of the CAN bus is only 1000Kbps. When it is really used, half the bandwidth is good. Let's understand the physical loss. Therefore, the biggest contradiction at present is the contradiction between the increasing bus bandwidth requirements of the people and the CAN bus cannot meet everyone's bus communication needs. What should I do? The CAN FD bus was introduced.
 
CAN FD can be regarded as an upgraded version of the speed of the CAN bus. Its maximum bandwidth has been upgraded from 1000Kbps to 5000Kbps, and the changes in the extra 4000K may be endless. In addition, because CAN FD is developed based on the CAN bus, you don’t need to use hardware and software to replace it when you replace it. You only need a special data converter to achieve universal use. The cost is very low. For example, Shenyang Guangcheng Technology Co., Ltd. has developed USBCAN II FD, which is specifically for this purpose. Let’s take a brief look at it.
 
Shenyang Guangcheng Technology USBCAN II FD type communication interface can device is a high-performance bus communication interface card with integrated 2-way CANFD interface. This type of communication interface can device conforms to the USB2.0 bus high-speed specification, has two independent CAN/CAN FD channels, and the signals are isolated from each other. The PC can be quickly connected to the CAN (FD)-bus network through the USB interface to form a CAN (FD)-bus network field data processing and data acquisition CAN (FD) in the field bus laboratory, industrial control, intelligent community, automotive electronics network, etc. )-Bus network control node.
Shenyang Guangcheng Technology's USBCAN II FD communication interface CAN device is a powerful tool for CAN (FD)-bus product development and CAN (FD)-bus data analysis. It also has the characteristics of small size, plug and play, and is also a portable system user. Good choice. The USBCAN-II FD interface card comes with a USB interface and integrates a CAN interface electrical isolation protection module to prevent damage to the device due to instantaneous overcurrent/overvoltage and enhance the reliability of the system in harsh environments.
