| description | The invention provides a data collection method and device. The data collection method comprises that when a user asks to collect data according to data demand time, latest demand time and latest data collection time of each variable are recorded in real time; sequences of the latest demand time and latest data collection time of the variables are compared; when the latest data collection time of certain variable is earlier than the latest demand time of the same, data corresponding to the variable is collected from a bottom device of the variable, and the latest data collection time of the variable is updated; and when the latest data collection time of certain variable is later than the latest demand time of the same, a data collection task is executed at heartbeat interval. Thus, data corresponding to variables of higher demand degree is collected in priority, and it is ensured that data corresponding to the variables of higher demand degree is collected in real time.
