PROBLEM TO BE SOLVED: To measure the action patterns of many persons in a building or a building site via a simple equipment by generating the different types of signals through plural transmitters placed in an action range to record the action patterns and then receiving and storing the signals in sequence through a portable receiver. SOLUTION: The signal transmitters 1 are placed at several points in a building, and a portable receiver 2 is carried by a person who moves about in an action range to receive and record the signals transmitted from the transmitters 1. The transmitters 1 produce and output the signals of different types from each other, and every receiver 2 judges the types of signals received from the transmitters 1 and stores these judged results in a memory part as data. Such data stored in the receiver 2 are collected by a data processor and statistically processed. Thus an action pattern is measured based on the behavior history of the person who carries the receiver 2 and moves about in the action range. |
