| 20080278317 | REAL-TIME MONITOR SYSTEM - A real-time monitor system including at least one public facility, a second wireless transceiver, and a control center is provided. The public facility includes a power generator, a load, a signal generator, and a first wireless transceiver. An initial power provided by the power generator drives the load. The signal generator determines whether or not to output a condition signal and a positioning signal according to whether the load is driven. Then, the condition signal and the positioning signal are emitted to the second wireless transceiver by the first wireless transceiver. Therefore, the control center determines the service condition of the public facility according to the information of the condition signal or whether the condition signal is received, and determines the position of the public facility according to the positioning signal. | 11-13-2008 |
