摘要

Systems and methods for updating software in a hazard detection system are described herein. Software updates may be received by, stored within, and executed by a hazard detection system, without disturbing the system's ability to monitor for alarm events and sound an alarm in response to a monitored hazard event. The software updates may be received as part of a periodic over-the-air communication with a remote server or as part of a physical connection with a data source such as a computer. The software updates may include several portions of code designed to operate with different processors and/or devices within the hazard detection system. The software updates may also include language specific audio files that can be accessed by the hazard detection system to play back language specific media files via a speaker.

說明書

High power wireless communications circuitry 212 can be, for example, a Wi-Fi module capable of communicating according to any of the 802.11 protocols. For example, circuitry 212 may be implemented using WiFi part number BCM43362, available from Murata. Depending on an operating mode of system 205, circuitry 212 can operate in a low power “sleep” state or a high power “active” state. For example, when system 205 is in an Idle mode, circuitry 212 can be in the “sleep” state. When system 205 is in a non-Idle mode such as a Wi-Fi update mode, software update mode, or alarm mode, circuitry 212 can be in an “active” state. For example, when system 205 is in an active alarm mode, high power circuitry 212 may communicate with router 222 so that a message can be sent to a remote server or device.
