Systems and methods for updating software in a hazard detection system
摘要
說明書
Hazard detection system 105 can implement multi-criteria state machines according to various embodiments described herein to provide advanced hazard detection and advanced user interface features such as pre-alarms. In addition, the multi-criteria state machines can manage alarming states and pre-alarming states and can include one or more sensor state machines that can control the alarming states and one or more system state machines that control the pre-alarming states. Each state machine can transition among any one of its states based on sensor data values, hush events, and transition conditions. The transition conditions can define how a state machine transitions from one state to another, and ultimately, how hazard detection system 105 operates. Hazard detection system 105 can use a dual processor arrangement to execute the multi-criteria state machines according to various embodiments. The dual processor arrangement may enable hazard detection system 105 to manage the alarming and pre-alarming states in a manner that uses minimal power while simultaneously providing relatively failsafe hazard detection and alarming functionalities. Additional details of the various embodiments of hazard detection system 105 are discussed below.
Enclosure 100 can include any number of hazard detection systems. For example, as shown, hazard detection system 107 is another hazard detection system, which may be similar to system 105. In one embodiment, both systems 105 and 107 can be battery powered systems. In another embodiment, system 105 may be line powered, and system 107 may be battery powered. Moreover, a hazard detection system can be installed outside of enclosure 100.
