A Data Acquisition Algorithm Based on Time Slot and Circular Queue

Multi-sources data acquisition under unattended condition is a representative problem in data acquisition. An intelligent data acquisition algorithm based on time slot and circular queue is brought forward, which is achieved in identity recognition and auto-weight with nobody on duty. It utilizes the timer interaction principle in Visual Basic and the character of data store and access in circular queue. On the basis of analyzing the system flow and data transportation protocols, the key parameters for the algorithm such as the length of time-block, the size of queue and the correlative algorithms of the circular queue are discussed, the relevant flow diagram is described, at last the running instance is given. Implement results in the garbage measurement project for Wuhan city administrative bureau have illustrated that the algorithm is effective and reliable.
