Paper Abstract

Three modes of Windows Multithread techniques in data acquisition system are explored in this paper. In the first mode, data acquisition is in one thread while the processing and display of data and the large-capacity data saving share another thread. In the second mode, data acquisition and the data processing and display are in one thread, and the large-capacity data saving in another thread. In the third mode, double level buffer queue technology is added based on the first mode technique. Experiments on the data acquisition system reveal that the third mode is the optimal alternative. It fully utilizes the capacity of data acquisition card and makes access to high-speed continual data acquisition and large-capacity data saving. The monitoring system which adopts the third mode has been developed and applied to some urban waterworks in Shanghai which has been in good mode during the past two years and saved a vast sum of costs on system maintenance and monitoring.
