SEAT-LEAVING PROCESSING METHOD, COMMUNICATION SYSTEM, AND CONTROL TARGET APPARATUS

摘要

PROBLEM TO BE SOLVED: To prevent the occurrence of false operation by a software processing without adding hardware when a seat-leaving processing is automatically carried out based on a reception power in short-distance wireless communication between a mobile terminal device and a control target apparatus. SOLUTION: The control target apparatus 100 collects device information (device data of a mobile terminal device 200 and that of the control target apparatus 100), and outputs the collected device information to a server apparatus 300. The server apparatus 300 searches parameter information that matches the device information from the parameter information including a reception power threshold that is preliminarily stored, and outputs the searched parameter information to the control target apparatus 100. After receiving and storing the parameter information, the control target apparatus 100 measures the reception power of a signal from the mobile terminal device 200, and determines as seat-leaving in the predetermined case where the reception power is equal to or less than the reception power threshold included in the parameter information to execute a predetermined seat-leaving processing.
