Based on the defects in the prior art, the embodiment of the application provides an ad hoc network smoke alarm system, and under the condition that network infrastructures such as switches and routers are not needed, synchronous alarm of fire information in a building or a park is achieved.
Fig. 1 shows a schematic structural diagram of an ad hoc network smoke alarm system provided in an embodiment of the present application, where the system includes: the system comprises an ad hoc network processor embedded in an ad hoc network communication protocol, a radio frequency module, a smoke sensor, a temperature sensor, an alarm, an indicator light and a power supply. The ad hoc network processor is a control core of the system, an internal program is embedded into an ad hoc network communication protocol, and the ad hoc network can be spontaneously formed with other smoke alarm node processors in a set range and can realize multi-hop forwarding of data.
The ad hoc network processor and the ad hoc network processor of the smoke alarm system in the set range form an ad hoc network; the ad hoc network processor is respectively connected with the radio frequency module, the smoke sensor, the temperature sensor, the alarm and the indicator light.
The smoke sensor is used for acquiring the smoke concentration in the ambient air in real time and sending a smoke sensing signal to the ad hoc network processor.
The temperature sensor is used for acquiring the ambient temperature in real time and sending a temperature sensing signal to the ad hoc network processor.
The ad hoc network processor collects the smoke sensing signals and the temperature sensing signals at regular time and sends the smoke sensing signals and the temperature sensing signals to the ad hoc network through the radio frequency module.
The ad hoc network processor is also used for carrying out fire judgment on the collected smoke data and temperature data, and when the smoke data and/or the temperature data are in an abnormal range, the alarm is triggered to give an alarm, the indicator light is controlled to flash, and a fire alarm signal is sent to the ad hoc network, so that other ad hoc network processors in the ad hoc network enter a fire alarm state. The processor runs a fire determination algorithm on the collected data and when the data of either of the two sensors exceeds a threshold, a fire is deemed to have occurred. The processor enters a fire alarm state. Under the fire alarm state, the processor controls the alarm to give an alarm, controls the indicator lamp to flash the red light, and sends the fire signal to the ad hoc network through the radio frequency module to remind other smoke alarm nodes of the fire.
In one possible implementation, the ad hoc network processor is further configured to: and collecting the smoke sensing signals and the temperature sensing signals in real time, stopping a fire alarm state and switching to a normal state when the smoke data and the temperature data are both restored to a normal range, and sending fire alarm relieving signals to other ad hoc network processors in the ad hoc network. Namely, the processor continuously collects the data of the smoke sensor and the temperature sensor, and when the two sensors are found to recover to normal values, the fire alarm state is cancelled, the normal state is switched back, and other nodes in the ad hoc network are informed.
In a possible implementation manner, after the other ad hoc network processors in the ad hoc network enter the alarm state, for each ad hoc network processor entering the alarm state, the method specifically includes: and triggering an alarm to send out an alarm, controlling the indicator light to flash, and forwarding a fire alarm signal to other ad hoc network processors in the ad hoc network which do not receive the fire alarm information so as to realize multi-hop communication among the ad hoc network processors.
Fig. 2 shows a schematic diagram of an ad hoc network of smoke alarms in a building according to an embodiment of the present application, where other nodes enter a fire forwarding state after receiving a fire signal and simultaneously sound an alarm and control an indicator light to flash a red light. Meanwhile, according to the ad hoc network communication protocol, the node forwards the fire signal to a node farther away, so that the whole building unit can give an alarm comprehensively.
In a possible implementation manner, when communication is disturbed or the transit ad hoc network processor node fails, the ad hoc network processor is further used for automatically searching other normally operating ad hoc network processors and forwarding a fire alarm signal, so that the other ad hoc network processors in the ad hoc network enter a fire alarm state.
The embodiment of the application can realize multi-hop communication. That is, one node finds the fire and sends the fire to the surrounding nodes, and the nodes can forward the fire information to the nodes farther away. Namely A- > B- > C- > D. If the problem of communication interference or node failure occurs, B cannot forward. Then the ad hoc network will automatically find a new path, A- > E- > C- > D, so that the coverage area can be enlarged, and the robustness of the whole network is improved.
In one possible embodiment, the system further comprises: a management server; and the ad hoc network processor connected with the management server is used for receiving fire alarm signals sent by other ad hoc network processors in the ad hoc network, and is also used for positioning a fire position according to a processor ID carried by the fire alarm signals so as to carry out personnel evacuation scheduling and fire extinguishing processing. The ad hoc network processor connected with the management server is responsible for receiving information sent or forwarded by each node. The server is not limited to buildings, but may be plants, parks, and the like.
In a possible implementation manner, the power supply is used for supplying power to the ad hoc network smoke alarm system, and the power supply is powered by a battery or a dual-power-supply mode of a wire and the battery.
In a possible implementation manner, the ad hoc network processor is further configured to monitor the electric quantity of the power supply, and when the electric quantity is lower than a threshold value, the node indicator light flashes yellow to prompt the battery replacement. And sending a battery replacement signal to the management server.
In one possible embodiment, the ad hoc network communication protocol includes, but is not limited to, Zigbee, 6LoWPAN, Z-Wave, or MESH. The ad hoc network does not need to additionally arrange a machine room, does not need to build basic facilities such as a switch and a router, and uses the multi-hop relay networking among the smoke alarm nodes as a springboard to cover the use range in a large area.
In a possible implementation, the radio frequency module mainly includes a filter and an antenna, and may further include a power amplifier.
In one possible implementation, the radio frequency module is connected to the processor and is responsible for transmitting information output by the node processor in the form of radio waves and receiving information from other nodes in the ad hoc network.
In one possible embodiment, the smoke sensor may be a photoelectric smoke sensor or a smoke sensor based on ionization principle. The smoke sensor is realized by adopting an optical scattering method, and specifically comprises the following steps: a pair of laser diodes and photodiodes placed at an angle in the optical maze, wherein the laser diodes emit laser light under the control of the ad hoc network processor and irradiate the optical maze, and the photodiodes receive light scattered by particles in the optical maze; when the concentration of smoke particles entering the optical maze is low, the particle scattering light received by the photodiode is weak, and the photoelectric signal collected by the ad hoc network processor is weak; when the concentration of smoke particles entering the optical maze is high, the signal collected by the photodiode by the ad hoc network processor is strong.
The embodiment of the application solves the problem that the existing smoke alarms cannot be interconnected with each other and depend on network infrastructure. The wireless ad hoc network smoke alarm can be widely applied to various occasions such as hotels, office buildings, residential buildings and the like. Different from the existing smoke alarm, the embodiment of the application has the advantages of self-networking, multi-hop cascading, node self-management and the like, and the cost and the complexity of network deployment can be greatly reduced. Each smoke alarm node in the whole building can be networked, so that when one smoke alarm finds fire, other nodes can be informed in time, and the situation that other floors are not burnt due to fire and alarm is not triggered is avoided. 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.
