With the development of China’s science and technology, more and more fields require industrial computer to do related data collection and control. Due to industries such as high-speed rail, subway, and aerospace, industrial computers are required to have a CAN bus. Because the price of CAN bus interface is high or low, many industrial computer manufacturers with standard interface do not have CAN bus. If a customer needs an industrial computer with CAN bus, what do they need to do?
The industrial computer has a CAN bus and can adopt 8 methods. It mainly depends on whether the industrial computer has the following interfaces.
1.USB interface to CAN bus
- – High-performance USB to multi-channel CAN-bus interface card, which is compatible with USB2.0 full-speed bus specification, integrates 1-8 CAN-bus interfaces, and the CAN channel integrates an independent electrical isolation protection circuit. The interface card connects the PC to the CAN network through the USB port to form a CAN-bus control node.
- – The USBCAN-I-mini high-performance CAN interface card is compatible with the full-speed specification of the USB2.0 bus, and it integrates a high-performance CAN-bus communication interface card with 1~2 CAN interfaces. Using the USBCAN-I-mini high-performance CAN interface card, the PC can be connected to the CAN-bus network through the USB bus to form data processing, CAN-bus network control node for data acquisition.
2.PCI interface to CAN bus
PCI series general CAN card, compatible with PCI 2.2 specification, high-performance CAN interface card with 1~4 CAN interfaces. Using the PCI interface CAN card, the PC can be connected to the CAN network through the PCI interface to form data acquisition and data processing in the CAN network fields such as laboratories, industrial control, and smart communities.
3.CPCI interface to CAN bus
The CPCI interface CAN bus card is a high-performance CAN interface card that complies with the PICMG 2.1 R2.0 specification, supports the CompactPCI Hot Swap Specification (hot swap), and has 2 CAN interfaces. Using the CPCI interface CAN card, the industrial computer can be connected to the CAN network through the CPCI interface to form data acquisition and data processing in the CAN network fields such as high-speed rail, rail transit, navigation, and testing.
4.MiniPCIe interface CAN card
The high-performance MiniPCIe interface CAN card can extend the motherboard with MiniPCIe card slot to two CAN interfaces. It adopts the standard MiniPCIe board size and can be easily installed on a laptop or industrial computer with MiniPCIe interface. It is one of the most commonly used CAN buses for fanless industrial computers.
5.Ethernet to CAN module
The Ethernet-CAN converter realizes the function of mutual transmission of CAN-bus data and Ethernet data. It integrates 1, 2, 4 CAN-bus interfaces and 1, 2 Ethernet interfaces or optical fiber interfaces, and comes with TCP/ IP or UDP protocol stack, users can use it to easily complete the interconnection and intercommunication of CAN-bus network and Ethernet network, establish Ethernet-CAN two-layer network architecture, realize remote control, and greatly expand the application range of CAN-bus network.
6.WiFi to CAN module
The WiFi converter realizes the function of mutual transmission of CAN-bus data and WiFi data. It integrates 2 CAN-bus interfaces, 1 WLAN interface and 1 LAN interface, and comes with TCP/IP or UDP protocol stack. It can easily complete the interconnection and intercommunication of CAN-bus network and WiFi network, greatly expanding the application range of CAN-bus network.
7.RS232/485/422 to CAN device
The industrial-grade intelligent protocol converter can quickly connect RS-232/485/422 communication equipment to the CAN-bus field bus to realize two-way communication.
8.PCIe interface CAN card
The PCIe interface CAN card is a PCI Express x1 specification CAN interface card, a high-performance CAN interface card with 2 CAN interfaces. The PC can be connected to the CAN network through the PCIe interface to form data collection and data processing in the CAN network fields such as laboratories, industrial control, and smart communities.
