Remote metering system and method for controlling polling period of end node using the same

摘要

The present invention relates to an automatic meter reading system and a polling period control method of an end node using the same. According to the present invention, in a polling period control method of an end node using an automatic meter reading system, the end node is switched from a sleep mode to an awake mode at a predetermined polling cycle to transmit a polling signal including meter reading data and battery use status data Calculating a remaining current amount of the end node using the battery use state data among the collected data of the end node using the router node, and transmitting the calculated current amount to the router node, Calculating a first polling period using a residual current amount if the node belongs to a predefined major activity time and selecting a pre-stored maximum polling period if the node does not belong to a main activity time, The first polling period or the maximum polling period Group provides a polling cycle, the control method of the end node comprises transmitting to the router node. According to the present invention, there is an advantage that the polling cycle of the end node can be changed and adjusted in the upper part based on the battery condition periodically collected from the end node, and the battery life of the end node can be maximized.
