Wireless fire system based on open standard wireless protocols

摘要

A wireless fire detection monitoring system comprises a control unit which includes a wireless transceiver and control software to implement a wireless multi-hop communications protocol. A network of battery powered monitoring devices is provided for monitoring alarm conditions. Each monitoring device includes software to implement the wireless communication protocol with one of, the control unit and at least one other child member of the plurality, or, at least two other members of the plurality where a selected device communicates with at least one child device and at least one parent device. The wireless multi-hop communications protocol comprises a time division multiple access communications protocol with the monitoring devices being time synchronized and the control unit and the monitoring devices are adapted to communicate compliant with the IEEE 802.11 standard.

1. A wireless fire detection monitoring system comprising:
a control unit which includes a wireless transceiver and control software to implement a wireless multi-hop communications protocol; and a plurality of battery powered monitoring devices where each device includes software to implement the wireless communication protocol with one of: the control unit and at least one other child member of the plurality; or at least two other members of the plurality where a selected device communicates with at least one child device and at least one parent device, wherein the wireless multi-hop communications protocol comprises time division multiple access (TDMA) communications with the monitoring devices being time synchronized and the control unit and the monitoring devices are adapted to communicate compliant with the IEEE 802.11 standard, the wireless multi-hop communication protocol using a communication system partitioned into abstraction layers comprising an uppermost application layer above a TDMA mesh routing layer which implements an algorithm for controlling time slot implementation for TDMA mesh routing, wherein the TDMA mesh routing layer performs TDMA mesh routing for the plurality of devices, the TDMA mesh routing layer being above a media access control (MAC) layer implementing the 802.11 communications.
