METHOD, DEVICE, SYSTEM, AND PROGRAM FOR AUTOMATIC DATA GATHERING

摘要

PROBLEM TO BE SOLVED: To efficiently gather data by an automatic data gathering system equipped with a master radio device and multiple slave radio devices. SOLUTION: (a) A specific function value regarding the number of slave devices which fail to gather data under the control of each master radio device and a specific reference value are used and compared with each other to judge a data gathering method, and then data are gathered by one of a batch data gathering method and a sequential data gathering method. (b) After the operation of (a), slave radio devices which fail to gather data are further determine and (c) the operations of (a) and (b) are repeated to gather data regarding the slave radio devices which should gather data under the control of the master radio device.
