Abstract

The invention discloses a configurable protocol conversion system and method based on network-on-chip data acquisition. The system comprises a configurable protocol converter, an interface protocol configurator, a data preprocessing and transmission module and a router, the configurable protocol converter comprises a reconfigurable interface and an on-chip network interface controller. Based on the interface technology of the network-on-chip chip and the external sensor, the reconfigurable interface circuit meeting the access requirements of various types of analog / digital interface sensors and the controller of the reconfigurable interface circuit are designed, and on the basis, the interface protocol can be configured by using a serial port, so that the problem that the interface protocols of different sensors are different is effectively solved, an interface can be configured to control synchronous sampling of the sensor, and synchronous acquisition of data is realized. According to the method, the data acquisition system has the capability of being connected with sensors with different interface standards, so that the application range and the flexibility of the system are improved, and the requirement of synchronous acquisition of data acquisition is met.

Description

technical field [0001] The invention relates to the technical field of on-chip network data acquisition, in particular to a configurable protocol conversion system and method based on on-chip network data acquisition. Background technique [0002] In data acquisition systems, sensors of different types and models are often required. However, there are great differences in the way these sensors are interfaced. This requires the data acquisition system to have the ability to connect sensors with different interface standards, thereby improving the adaptability and flexibility of the system. [0003] At present, the chassis-type data acquisition unit realizes this function by replacing different data acquisition modules. In order to enable the data collector to support different smart sensor communication protocols and improve the applicability of the chip, it is necessary to explore how to use reconfigurable technology to design the interface between the chip and the sensor....
