| 摘要 |
A low cost, robust, wireless sensor that provides an extended period of operability without maintenance is described. The wireless sensors are configured to communicate with a base unit or repeater. When the sensor unit detects an anomalous ambient condition (e.g., smoke, fire, water, etc.) the sensor communicates with the base unit and provides data regarding the anomalous condition. The sensor unit receives instructions to change operating parameters and/or control external devices. |

1. A system for monitoring and reporting on environmental conditions within a building, comprising:
a base unit in wireless communication with a wireless repeater, the base unit being operable to:
communicate with one or more components of the system using both wireless communication and power line communication;receive messages from one or more sensor units that comprise smoke sensors via the wireless repeater;receive, from a sensor unit via the wireless repeater, an emergency condition indicator indicating the existence of an emergency condition, the emergency condition indicator being generated by and communicated from the sensor unit in response to the sensor unit detecting, via a smoke sensor, an amount of smoke within the building that is outside of a threshold value for smoke, wherein the sensor unit includes a location identifier that identifies a location of the sensor unit within the building;receive the location identifier, from the sensor unit via the wireless repeater when the emergency condition indicator is generated by and communicated from the sensor unit; andcommunicate the location identifier to a computing device; and the computing device communicatively coupled to the base unit and a user device located outside of the building, the computing device being operable to:
receive, from the base unit, information indicative of the emergency condition in response to and after the base unit receives the emergency condition indicator from the sensor unit via the wireless repeater;receive the location identifier from the base unit;access a stored list that relates locations with location identifiers;communicate, to the user device and via the Internet, a notification of the emergency condition in response to and after receiving, from the base unit, the information indicative of the emergency condition; andcommunicate, to the user device and via the Internet, information indicative of the location of the sensor unit as associated with the location identifier such that the user device receives an indication of the location of the sensor unit that detected the amount of smoke within the building that is outside of the threshold value for smoke. |
