Abstract

Real-time property is one of the most important properties of the data acquisition and processing system. The working principle and designing ways of the data acquisition and processing system was briefly introduced and the factors affecting the real-time property of the system was emphatically analyzed in this paper. In order to design and implement a real-time dual-channel simultaneous data acquisition and processing system, the techniques of dual CPU, HPI (Host Port Interface) and ping-pong buffer strategy were adopted, all of which were important guarantees of the real-time property. Some conclusions obtained in this paper can be of significance to the similar engineering.
