A Synchronous Serial Signal Acquisition Control Device Based on Gigabit Ethernet

Abstract

The invention discloses a synchronous serial signal collection control device based on the Gigabit Ethernet, and the device comprises an SSI signal collection device, a main control unit, a Gigabit Ethernet communication device, and an upper computer; The Gigabit Ethernet communication device achieves the connection with the SSI signal collection device through the main control unit. The SSI signal collection device is directly connected with an external sensor, and collects the original data of the sensor. The upper computer and the Gigabit Ethernet communication device employ a UDP for datatransmission, and a network line which supports the Gigabit transmission rate is required for the hardware connection. The device employs the Gigabit Ethernet communication interface. Compared with aconventional PCI and a USB bus, the device greatly increases the transmission rate, so the device can support a peripheral sensor with the larger number of collection channels and higher collection frequency. Meanwhile, the Ethernet interface is convenient to connect, and the device is longer in communication distance. The device also can be connected with the Ethernet switch, a personal PC and anindustrial control computer, is flexible in networking, is reliable in transmission, and is low in cost.

Description

technical field [0001] The invention relates to a data acquisition and control device in the field of industrial measurement and control, in particular to a gigabit Ethernet-based synchronous serial signal acquisition and control device. Background technique [0002] Data acquisition is an important link in the field of industrial production. The premise of realizing industrial control is to collect and transmit important data in industrial production to the control device, and data acquisition must meet the requirements of real-time and accuracy in order to ensure that the industrial production process can be obtained. Good detection and control. In industrial applications such as assembly lines and robotic arms, the monitoring of position information such as displacement and angle is particularly important. This information is generally collected by position sensors such as photoelectric encoders. Absolute encoders, linear displacement sensors and other sensors widely use...
