An integrated high-reliability and high-precision long-term monitoring system

Abstract

The invention relates to an integrated high-reliability and high-precision long-term monitoring system which comprises the components of two alternate acquiring-and-coding units, two integrated controllers, a switch, two monitoring computers, a plurality of first sensors and a plurality of second sensors. According to the integrated high-reliability and high-precision long-term monitoring system, through improvement and innovation of a traditional data acquisition, coding, transmission and demodulation processing method, based on a serial communication interface and an industrial Ethernet, problems of complicated system equipment structure, low precision and insufficient long-term reliability are settled, and advantages of high reliability, high precision and long-term monitoring are realized. According to the integrated high-reliability and high-precision long-term monitoring system, in an integration aspect, integrated design is performed on key equipment of the system, number of equipment components is reduced and system complexity is reduced; in a transmission real-time performance aspect, data transmission is finished based on a serial bus and the Ethernet, thereby ensuring no performance reduction in actual use caused by transmission delay time; and in a long-term reliability aspect, through utilizing a redundancy design and other reliability design measures on the key equipment, continuous operation time of the product is prolonged.

Description

technical field [0001] The invention relates to an integrated high-reliability and high-precision long-term monitoring system, which belongs to the technical field of monitoring and monitoring and is applied to real-time monitoring and alarming in the industrial field.
