[0026] The utility model discloses a building intelligent alarm system. Figure 1 This is a schematic diagram of the composition of the building intelligent alarm system in one embodiment of the utility model; please refer to Figure 1 , the building intelligent alarm system comprises: at least one light source module 1 and at least one sensor module 2;

[0027] The light source module 1 includes a first control circuit 11, a wireless routing module 12, a first wireless communication module 13, a light emitting unit 14 and a speaker 15. The first control circuit 11 is respectively connected to the wireless routing module 12, the first wireless communication module 13, the light emitting unit 14 and the speaker 15. The light source module 1 forms a network with the setting sensor module 2 through the wireless routing module 12; at the same time, the light source modules 1 in the setting area can communicate information through their first wireless communication modules 13; the light emitting unit 14 is used to emit light, and the speaker 15 is used to play alarm information.

[0028] The sensing module 2 includes a second control circuit 21, a second wireless communication module 22 and a sensor 23, wherein the second control circuit 21 is connected to the second wireless communication module 22 and the sensor 23 respectively; the sensor 23 is used to sense a setting signal and send it to the second control circuit 21; the second control circuit 21 can send the signal received from the sensor to the setting light source module 1, or / and the second control circuit 21 processes the signal received from the sensor 23 and can send the processed information to the setting light source module 1.

[0029] At least one of the light source modules 1 further includes a third wireless communication module 16 , and the light source module 1 accesses an external network through the third wireless communication module 16 , thereby being able to send alarm information to a communication device of the external network.

[0030] In one embodiment of the utility model, the light source module 1 further includes an alarm information transmission module 17, and the alarm information transmission module 17 is used to send the alarm information to other light source modules within a set range after obtaining the alarm information. In one embodiment, the first control circuit controls the operation of the alarm information transmission module; if a light source module that has forwarded once within a set time hears the forwarding information of other light source modules again, it will not forward it again.

[0031] The sensor 23 of the sensor module 2 may include at least one of a temperature sensor, a water immersion sensor, a set gas sensor, and a camera. The first wireless communication module 13 and the second wireless communication module 22 may include at least one of a Wi-Fi communication module, a Bluetooth communication module, a Zigbee communication module, a Thread communication module, a Matter communication module, an 802.15.4 protocol communication module, and a SubG communication module. The third wireless communication module 17 may be a cellular network module, or other communication modules that can access an external network. The sensor module 2 further includes a battery module 24, which supplies power to the electrical components of the sensor module 2.

[0032] The light source module 1 can be a lamp with an integrated wireless module 14 and a speaker 15, and can be powered by the municipal power grid; the utility model can be used to transform existing corridor lights; the existing corridor lights can be upgraded to a three-in-one lighting device of "corridor lights + speakers + wireless modules". In smart buildings, various sensors with wireless modules are used. The sensor type can be a temperature sensor (which can detect fires), a water immersion sensor (which can detect water leaks), a CO2 / CO sensor (which can detect fires, gas leaks, dust and other disasters), or a camera (through AI video analysis of abnormal situations, such as debris piled up in fire passages, etc.). The corridor lights and various sensors form a network, and any device can communicate with each other. The wireless modules used by corridor lights and various sensors can be, but are not limited to, the following technologies: Wi-Fi, Bluetooth, Zigbee, Thread, Matter, 802.15.4, SubG, etc.

[0033] There are also several corridor lights in the system that have the function of a gateway. In one embodiment, several gateways are used instead of one to prevent a single gateway from making a mistake and the system being unable to transmit the abnormality to the external network. The corridor lights with gateway functions can be equipped with a cellular module based on the above three-in-one lighting device to transmit the abnormality to the external network, such as notifying the fire department.

[0034] When various sensors detect an abnormality, they immediately transmit the information to the three-in-one corridor lights through the wireless module. The corridor lights will enter the flashing alarm state and the horn will sound. At the same time, the corridor lights will continue to forward and transmit through the wireless module. Eventually, the corridor lights of the entire building will enter the alarm state. At the same time, after receiving the abnormality, the gateway will automatically notify the property management, fire department, etc. to handle the disaster emergency.

[0035] The corridor lights are powered by the mains, so their wireless modules are always in working condition. When an abnormal state occurs, the information can be quickly transmitted to corridor lights that are close to them, and the nearby corridor lights will continue to transmit the message to other nearby corridor lights. This transmission process will continue until the corridor lights of the entire building enter the alarm state. Because its wireless module is always in working condition, the transmission is very fast, and all corridor lights in the entire building can enter the alarm state within a few seconds. The network flooding forwarding strategy can be used here, but some optimizations are made in the details to prevent network congestion. For example, if a device that has forwarded once within a certain period of time hears the forwarding of other devices again, it will not forward again. This strategy has a certain degree of unreliability for a network with sparse nodes, but it is reliable for a building with dense corridor lights. A network with sparse nodes generally means that only two nodes can communicate with each other, and cross-node communication is impossible. As for the density of corridor lights, the wireless signal forwarded by a corridor light can often be received by 5-10 adjacent corridor lights.

[0036] Various sensors can be battery powered. In design, the sensor can be awakened once every few seconds or tens of seconds for detection. The higher the wake-up frequency, the lower the delay in detecting anomalies, but the battery life will also be shorter. In design, a balance point can be obtained by comprehensive consideration. Each wake-up check takes several milliseconds to tens of milliseconds. If no abnormality is detected, wireless communication can be omitted to further save power consumption. According to the above strategy, the sensor is in a dormant state for about 99% of the time, which can greatly improve the battery life. Regarding reducing the duration of each wake-up, optimization can be carried out from multiple angles: more than 99% of the cases of each wake-up will not cause an abnormality, so all the work is repetitive. For this type of repetitive work, the execution speed can be increased by running the code on a fast medium, or the tasks during the wake-up period can be reasonably arranged to achieve parallelism as much as possible. For example, some sensors have a warm-up preparation time, so the sensor can be preheated in advance. During the sensor warm-up preparation process, the code first completes other tasks, such as network handshake interaction with corridor lights.

[0037] Figure 2 This is a flow chart of the alarm method of the building intelligent alarm system in one embodiment of the utility model; please refer to Figure 2In one usage scenario of the utility model, the alarm method of the building intelligent alarm system includes: the light source module builds a wireless network through its wireless routing module, so that the light source module forms a network with the set sensor module through the wireless routing module; the sensor module senses the set signal, and sends the sensed signal to the light source module directly or after processing through wireless communication; the light source module determines whether an alarm is required based on the signal sent by the received sensor module, and if an alarm is required, the alarm is issued through a loudspeaker; at the same time, alarm information is generated and sent to other light source modules in the set area; after receiving the alarm information, other light source modules alarm through the loudspeaker and send the alarm information to other light source modules in the set area.

[0038] In summary, the building intelligent alarm system proposed by the utility model can detect various anomalies and disasters in the building more quickly, and promptly notify all people in the building to evacuate in time, thereby avoiding casualties to a great extent.
