Abstract

The invention discloses a real-time monitoring bus technology-based computer measurement and control system. The system comprises a computer bus and a real-time measurement and control bus, wherein the computer bus is in bidirectional connection with the real-time measurement and control bus through a bus conversion board; a digital quantity input board, a digital quantity output board, an analogue quantity input board and an analogue quantity output board which are in bidirectional communication connection with the real-time measurement and control bus are hung on the real-time measurement and control bus. The real-time monitoring bus technology-based computer measurement and control system has the beneficial effects that the measurement and control bus can be kept relatively independent by connecting the computer bus and the measurement and control bus through the bus conversion board, so that the upgrade and the updating of a host computer are facilitated; moreover, the operating reliability of the host computer is increased. The structure has an obvious benefit that the using performance of an I / O (input / output) template on the measurement and control bus is not affected when the computer is upgraded and updated and even replaced by different types of host computers.

Description

technical field [0001] The invention relates to the technical field of computer measurement and control systems, in particular to a computer measurement and control system based on real-time measurement and control bus technology. Background technique [0002] The computer measurement and control system has been more and more widely used in the field of automatic testing and industrial automation, and has become an important symbol of transforming traditional industries with modern information technology.
