PURPOSE:To provide a data collection system improving the processing capacity of the entire system by controlling the load of the terminal controller without deteriorating the line utilization efficiency. CONSTITUTION:In data collection, system, each terminal equipment P1i stores the number of data transfers to a terminal controller 20a, the terminal controller 20a stores the number of receptions of data to be transferred by each terminal equipment P1i, and each equipment P1i decides the presence or absence of the coincidence of the number of transmissions/receptions individually by each data transmission end so as to judge whether or not the data collecting state in the terminal controller 20a is normal. Based on the result, the data collection state in the data collection file F1 is recovered to a normal state. |
