The life and property safety of people is protected.
In one possible implementation, the ad hoc network protocol may be implemented using Zigbee technology. The processor is implemented using CC2530 from TI or EFR32MG21 from Silicon labs. The two processor chips are SOC chips with the radio frequency communication module integrated inside, and system control and Zigbee communication can be realized. Zigbee is a low power consumption personal area network protocol based on the ieee802.15.4 standard. Its advantages are low complexity, self-organization, low power consumption, low data rate and low cost. The wireless data transmission network can realize the self-networking of the smoke alarm in the building and the multi-hop forwarding communication of data, and is high in reliability. Each Zigbee node can not only collect and monitor data of the connected sensor in real time, but also automatically transfer data transmitted from other nodes.
The processor collects signals sent by the smoke sensor and the temperature sensor at regular time and sends the collected data to the ad hoc network through the radio frequency module. In order to save the electric quantity of the smoke alarm, the collection interval can be set to be 1 minute to 10 minutes in a normal state. The smoke sensor can adopt a photoelectric smoke sensor or a smoke sensor based on an ionization principle. The temperature sensor is realized by a DS18B20 chip. And the processor operates a fire judgment algorithm on the acquired data, judges that a fire disaster occurs when any numerical value of the smoke sensor and the temperature sensor exceeds a threshold value and is abnormally increased, and enters a fire alarm state.
In a possible implementation mode, in a fire alarm state, the processor controls the alarm to give an alarm, controls the indicator light to flash the red light, and sends a fire signal to the ad hoc network through the radio frequency module to remind other smoke alarm nodes of the fire. The processor collects data of the smoke sensor and the temperature sensor every 1 second, and when the two sensors are found to recover to normal values, the fire alarm state is cancelled and the fire alarm state is switched back to the normal state, and other nodes in the ad hoc network are notified.
In a possible implementation, in the case of using the CC2530 chip as a processor, since the radio frequency signal transceiver circuit is already integrated inside the chip, the peripheral radio frequency module can be implemented only by the filter circuit and the antenna. In special circumstances, such as basements or when nodes are far apart, the rf module may add a power amplifier.
In one embodiment, each smoke alarm node may cover the entire building with fire information via multiple retransmissions. A multi-hop communication scheme is shown in fig. 3, and when one of the smoke alarm nodes a finds a fire, it may be forwarded to node G through node C. When the C node cannot forward information due to communication interference or node failure. The ad hoc network can automatically find other paths, such as an A- > B- > E- > G path or an A- > D- > F- > G path, and send information to the remote node G.
