Title:
REMOTE MONITORING SYSTEM
Document Type and Number:
Japanese Patent JP3633180
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To obtain a remote monitoring system whith which remote communication circuits and electric supply wires are easily arranged, and a number of monitoring devices are easily arranged.
SOLUTION: A monitoring device has one or plurality of sensors 100 and sensor I/F parts 99 for receiving information of an monitored object, and a radiocommunication device 25. Such monitoring devices are arranged on the monitoring positions. Each monitoring device has a battery as a driving source. Command is supplied from a radiocommunication device 15 on the host side to the monitoring devices. Information sensed by the sensors are transmitted by the monitoring devices through radiocommunication. The command and sensed information are transmitted through the adjacent monitoring devices to the host by means of the radiocommunication device 25, and vise versa.
