WIRELESS METER READING SYSTEM, AND WIRELESS METER READING METHOD

摘要

PROBLEM TO BE SOLVED: To solve the problem that a wireless slave device operating as a repeater during repeating use of a wireless meter reading system is fixed and battery life of the wireless slave device can not be maintained. SOLUTION: The wireless slave device has a meter-reading request transmitting means 601, a meter-reading answer receiving means 602, and a meter-reading answer transmitting means 603 as repeating operations when a repeating specification message by the repeating specifying means 701 of a wireless master device is received. The meter-reading request transmitting means 601 transmits a meter-reading request to a wireless slave device as the object of meter reading included in the repeating specifying message. The meter-reading answer receiving means 602 receives a meter-reading answer from the wireless slave device to which the meter-reading request is sent. The meter-reading answer transmitting means 603 transmits meter-reading answers gathered by the meter-reading answer receiving means 602 to the wireless master device. COPYRIGHT: (C)2008,JPO&INPIT
