Car can protocol analysis tool usage

Nowadays, many car manufacturers choose CAN bus as the communication bus of the car, because the CAN bus has fast data transmission speed and strong anti-interference ability, and can connect many node devices. Compared with other serial buses such as 232, it has unparalleled advantages. Sometimes the control distance of some CAN bus applications is long, and the CAN bus is a bit difficult, but this does not hinder our use of it. We can extend its effective data transmission distance using fiber or Ethernet as a medium. It is precisely because of these advantages that it is in the two areas of industrial production and vehicle control, especially in the field of vehicle control.

Luxury car using CAN bus

 

 

As long as it is a modern car, whether you are a few million luxury cars or tens of thousands of affordable cars, the CAN bus is the best helper you can use to control the entire car. Since the car is a consumable item, we basically use it every day. Therefore, the CAN bus will be as aging and problematic as other parts of the car. Because the CAN bus is the key device responsible for driver command communication. Therefore, if the CAN bus does not work or is slow, it will cause serious traffic accidents. Who can be responsible for this responsibility?

 

Therefore, just as if someone is sick, they will go to the hospital for treatment, and they will have to do an examination when they are fine. The car CAN bus should also be taken care of by the owner. Check if the equipment is running stably. If there is a problem, it must be eliminated in the first time. The equipment that can do this kind of work is the car can protocol analysis tool, which can also be called the car CAN bus analyzer. Below, let's talk about some issues that the car can protocol analysis tool should pay attention to when using it.

 

 

1, car can protocol analysis tools have many different types, according to the number of channels, can be roughly divided into single-channel car can protocol analysis tools, dual-channel car can protocol analysis tools and multi-channel car can protocol analysis tools. The more channels, the more powerful the function, but the inevitable volume and weight will increase, and it is not necessarily convenient to carry. Therefore, in addition to some special CAN bus detection projects, most of the CAN analysis tools can be completed using a single-channel or dual-channel automotive can protocol analysis tool.
 

Different types of car can protocol analysis tools

 

2. As stated in the first article, there are many types of automotive can protocol analysis tools depending on the number of CAN channels. Single-channel or dual-channel automotive can protocol analysis tools are typically powered by a USB cable when in use. The multi-channel car can protocol analysis tool, because of its high power, requires more power support. Therefore, when using these large car can protocol analysis tools, be sure to use an external power supply.

 

3. When performing CAN data monitoring on a car, the general method is to connect a car with a CAN data detection software to a car can protocol analysis tool, and the two sides are connected by a USB cable. There are two ways to connect the car can protocol analysis tool to the car, which is determined by whether there is a gateway at the OBD interface of the car. If the OBD interface of the detected vehicle is set up by the manufacturer, then there is no way to connect and receive data directly through the car can protocol analysis tool with the OBD interface. The car CAN protocol analysis tool with CAN interface must be used to bypass the car gateway and directly connect to the internal CAN line to realize the connection between the car and the computer. In most cases, we use the second method, such as the Shenyang Guangcheng Technology USBCAN II PRO car can protocol analysis tool is the best tool for your work.

 

 

Shenyang Guangcheng Technology's USBCAN II PRO car can protocol analysis tool is a high-performance CAN-bus bus communication interface card with integrated 2-channel CAN interface. This model car can protocol analysis tool is compatible with USB2.0 bus full speed specification, using USBCAN II PRO type car can protocol analysis tool, PC can quickly connect to CAN-bus network through USB interface, constitute field bus laboratory, industrial control, intelligent CAN-bus network control node for data processing and data acquisition in the CAN-bus network field such as residential area and automobile electronic network.
