Problems solved by technology

In order to collect as much experimental data as possible during the road test and reduce labor intensity, the current CAN gateway lacks wireless communication functions
[0003] It can be seen that the above-mentioned existing CAN gateway obviously still has inconvenience and defects in structure and use, and needs to be further improved urgently.
In order to solve the above-mentioned problems, the relevant manufacturers have tried their best to find a solution, but for a long time no suitable design has been developed, and the general product has no suitable structure to solve the above-mentioned problems. This is obviously the relevant industry. Urgent problem

Abstract

The invention relates to a controller area network (CAN) gateway with a wireless transmission function. The CAN gateway with the wireless transmission function is characterized by comprising a fist CAN interface, a second CAN interface, a first CAN bus transceiver, a second CAN bus transceiver, an erasable programmable storer and a wireless network interface. Therefore, the CAN gateway with the wireless transmission function integrates the wireless network interface and the CAN gateway into a whole, can be used as a gateway of automobile electrical equipment, and can be used as remote control or remote upgrade to a CAN bus product. According to the CAN gateway with the wireless transmission function, two channels of CAN interfaces and the wireless network interface (which can be selectively assembled with a general packet radio service (GPRS) module or a code division multiple access (CDMA) module) are provided. An automobile battery is used for supplying power, and messages in a mobile body interwork can be collected and transmitted to a far-end server. A certain electrical device on a faraway automobile can be upgraded from the far-end server.

Description

technical field [0001] The invention relates to the field of automotive electronics, in particular to a CAN gateway with wireless transmission function. Background technique [0002] With the rapid development of automotive electronics, CAN bus products are more and more widely used in motor vehicles. After rigorous laboratory tests, automotive electronic products must also undergo long-term road tests before they can provide products for vehicle manufacturers. In order to collect as much experimental data as possible during the road test and reduce labor intensity, the current CAN gateway lacks wireless communication functions. [0003] It can be seen that the above-mentioned existing CAN gateway obviously still has inconvenience and defects in structure and use, and needs to be further improved urgently. In order to solve the above-mentioned problems, the relevant manufacturers have tried their best to find a solution, but no suitable design has been developed for a long ...
