This paper introduces some features of usb-can2 device

In recent years, the battle between AMD and Intel in the field of processors has intensified. Both sides have launched their top flagship CPUs in their respective fields, one is i9 with 18 core and 36 threads, the other is thread Ripper with 16 core and 32 threads. Of course, no matter which one is, it seems too wasteful for our normal office needs. At the same time, the price is also very touching, which is not acceptable to US civilians. I don't know when to start, the number of computer CPU cores is more and more. I remember that the sixth generation of i7 processor a few years ago was only four cores and eight threads. As a result, dozens of physical core CPUs are common in recent years. Although the number of cores does not represent everything, more and more cores are really needed to be superior. A large number of cores means a large number of channels, a large number of three-level caches, and a large number of everything. In fact, the CPU's function depends on these parameters. Therefore, in the foreseeable future, this method of stacking cores to expand the number of channels will continue for a long time. Do you think only computer CPU will care about the number of cores and channels? Otherwise, in fact, the CAN bus analyzer also pays attention to this point, because the single channel can bus analyzer is really different from the dual channel can bus analyzer. Let's talk about this.

Before introducing the CAN Bus Analyzer, we need to talk about its carrier can bus, which is a simple name of controller area network and a common industrial field bus. Compared with other types of industrial bus, can bus has faster data transmission speed, stronger anti-interference ability, a large number of node equipment that can be connected, and low maintenance cost in the later period. In addition to the data communication distance of up to 10km, it is known as one of the most promising industrial bus, widely used in tram control, fire control host networking, and industrial automation Control, artificial intelligence development, automotive electronic product development and other fields. Because can bus is the standard bus on the car, which is responsible for the control and communication of the car, once can bus has problems, it will harm the life safety of drivers to a certain extent. Therefore, we must maintain the CAN bus just as we usually maintain the automobile engine and tire, and the equipment for this work is the CAN Bus Analyzer. However, many of these products have such shortcomings. Let's analyze them briefly:

 

If you use a single channel can bus analyzer to detect the target can bus, it's really easy to carry. Generally, it's only the size of the palm, which can be transported by putting it into the pants pocket. However, because it has only one can bus channel, it can only unilaterally direct the received data to the computer equipped with detection software for analysis, and complete the mutual conversion between CAN bus data and USB data. It is impossible to automatically receive can data unless you have another similar device, which is the feature of single channel can bus analyzer. What about multi-channel CAN Bus Analyzer? For example, 8-Channel or even 16 channel can bus analyzer can be seen on the market. Yes, they can be used for any kind of CAN bus detection, the spontaneous self collection of data and the self detection of equipment. However, with the increase of the number of CAN bus channels, the volume of such devices is also expanding, the weight is quite amazing, and it is not convenient to carry. In addition, using these big guys to carry out some simple can bus analysis tools, there is a sense of killing chickens with ox knife, resulting in a waste of resources. Therefore, in view of the advantages and disadvantages of single channel and multi-channel can bus analyzers, engineers have launched a dual channel can bus analyzer, namely usb-can2 device, which has the characteristics of exquisite and portable single channel can bus analyzer. At the same time, the dual channel can complete the data transmission between the two channels, achieve the spontaneous self collection, and realize the self detection by the way. It is a very ideal can bus analyzer tool. Among the numerous usb-can2 devices, the usb-can2 tool of usbcan-ii pro of Shenyang Guangcheng technology is undoubtedly the leader.

Usbcan-ii Pro usb-can2 tool of Shenyang Guangcheng technology is a high-performance can bus communication interface card integrating two can interfaces. The usb-can2 tool is compatible with USB2.0 bus full speed specification. The usb-can2 tool of usbcan-ii Pro is adopted. PC can be connected to can bus network quickly through USB interface, forming can bus network control node for data processing and data collection in CAN bus network fields such as field bus laboratory, industrial control, intelligent community, automobile electronic network, etc.

 

Usbcan-ii Pro usb-can2 tool of Shenyang Guangcheng technology is a powerful tool for CAN bus product development and can bus data analysis. It has the characteristics of small size, plug and play, and is also the choice of portable system users. Usbcan-ii Pro usb-can2 tool has its own USB interface, integrated with can interface electrical isolation protection module, so as to avoid equipment damage due to instantaneous overcurrent / overvoltage, and enhance the reliability of the system in harsh environment.
