Common industrial camera cable interface types are as follows:
1. USB interface
A USB interface camera is a digital camera that directly outputs digital image signals. The full name of USB is Universal Serial Bus (Universal Serial Bus). The USB interface is 4 "pins", of which 2 are power lines and 2 are signal lines. USB is a serial interface, which is hot-swappable and easy to connect. USB2.0, the transmission speed is 480Mbps, the communication distance is 5m, and 80 percent of the bandwidth is used for image transmission. USB3.0, the transmission speed is 4.8Gbps, the communication distance is 10m, and 80 percent of the bandwidth is used for image transmission. Because the USB interface camera is easy to use and has a wide range of interfaces, it is currently widely used in microscopes, scientific research experiments, portable equipment and other industries.
2. IEEE1394----FireWire interface
The 1394 interface, also known as "FireWire", is used to connect digital products to computers and other machines. IEEE1394 bus is a high-speed serial bus, the highest transmission speed of 1394a is 400Mbps, and the highest transmission speed of 1394b is 800Mbps. IEEE1394 supports hot-plugging, real-time data transmission, using bus structure, and plug-and-play. The 1394 interface is divided into 4 cores and 6 cores. There are two pairs of data cables in the 4 cores. In addition to the data cables, the 6 cores also include a set of power cables to supply power to external devices. The IEEE 1394 interface does not require a controller, and can achieve peer-to-peer transmission. The maximum transmission distance of 1394a is 4.5 meters, and the transmission distance of 1394b is usually 10 meters. It can be extended to 100 meters (100Mbps) under the condition of reduced data rate. Relay equipment is used. Support can further increase the transmission distance.
3. Camerlink interface
The digital image signal communication interface protocol introduced by the AIA Association is a serial communication protocol. Adopt LVDS interface standard, with fast speed, strong anti-interference ability and low power consumption. Developed from Channel link technology, some transmission control signals are added on the basis of Channel link technology, and some related transmission standards are defined. The protocol adopts MDR-26-pin connector or SDR-26-pin connector, which has the characteristics of high speed, bandwidth up to 6400Mbps, strong anti-interference ability and low power consumption.
4. Gige Gigabit Ethernet interface
Created and promoted by AIA (Automatde Imaging Association), it is a camera interface standard developed based on the Gigabit Ethernet communication protocol. Ideal for industrial imaging applications to transmit uncompressed video signals over a network. It is a standard for transmitting images over long distances using inexpensive cables.
5. CoaXPress
CoaXPress is an asymmetric high-speed point-to-point serial communication digital interface standard with a transmission speed of up to 6.25Gbps and a transmission distance of more than 100m. The data transmission volume is large, the transmission distance is long, and the transmission distance and transmission volume can be selected: from 50m@6.25Gbps to 170m@1.25Gbps, the price is low, it is easy to integrate, and it supports hot plugging.
