Title:
MANAGEMENT SYSTEM FOR AN UNDERGROUND MUNICIPAL GAS FACILITY
Document Type and Number:
WIPO Patent Application WO/2011/068285
Kind Code:
A1
Abstract:
The present invention relates to a management system for an underground municipal gas facility, and particularly, to a management system for an underground municipal gas facility, the system being configured with a sensor network in the underground municipal gas facility to enable the remote sensing of the conditions in the underground municipal gas facility in real time, thereby improving safety, rendering maintenance and management efficient, and preventing gas accidents from occurring and enabling a quick response in the event a gas accident does occur. The management system for an underground municipal gas facility of the present invention comprises: a sensor for outputting, to a transmitter, sensing data on sensed condition information of the underground municipal gas facility; said transmitter, which is installed in an underground area, for using a first protocol having a first frequency to transmit the sensing data input from the sensor to a converter installed in an above-ground structure; said converter for converting the data transmitted from the transmitter to a second protocol having a second frequency, and then transmitting the converted data to a collector; and said collector for transmitting the data transmitted from the converter to a remote server. Further, the management system may also comprise a repeater including at least one hop, for using the second protocol having the second frequency to relay and transfer the data transmitted from the converter to the collector.
