METHOD AND SYSTEM FOR DETECTING AND LOCATING TRAPPED PEOPLE |
| 摘要 |
A method and system for detecting and locating trapped people are provided. The method includes the following steps: (a) transmitting a first wireless signal based on a transmission power, and recording the transmission power; (b) when a first mobile device registers to the system for detecting and locating trapped people in response to the first wireless signal, recording identity information of the first mobile device; (c) determining whether the transmission power is a maximum transmission power; (d) if no, increasing the transmission power, and repeating the steps (a) to (d); if yes, calculating a relative location between the first mobile device and the system for detecting and locating trapped people based on the recorded transmission power and the recorded identity information. |

1. A locating method based on dynamically adjusted transmission power, adapted for a system for detecting and locating trapped people, the locating method comprising:
(a) transmitting a first wireless signal based on a transmission power, and recording the transmission power; (b) when a first mobile device registers to the system for detecting and locating trapped people in response to the first wireless signal, recording identity information of the first mobile device; (c) determining whether the transmission power is a maximum transmission power; (d) if no, increasing the transmission power and repeating steps (a) to (d); and (e) if yes, calculating a relative location between the first mobile device and the system for detecting and locating trapped people based on the recorded transmission power and the recorded identity information. |
