In recent years, with the rapid rise of emerging technologies such as internet of things, artificial intelligence, big data and the like, an intelligent concept is rapidly popularized in the building construction field, and how to make building space safe, comfortable, convenient, low-carbon and efficient becomes a problem concerned by many enterprises. Along with the increasingly accelerated urbanization process, urban buildings are dense and complex in structure, the fire environment is greatly changed, and the fire hazard is increased, so that the establishment of a set of complete intelligent building fire-fighting system plays a vital role in guaranteeing the personal safety and property safety of residents.
The intelligent building control system in the prior art mostly starts from the aspects of comprehensiveness, stability and the like of fire safety monitoring to ensure that when a fire disaster occurs, various system devices in a building such as illumination, anti-theft alarm, fire alarm and the like are subjected to data acquisition and dynamic control, and further comprehensive information monitoring and intelligent control are realized. For example, chinese patent ZL202110162111.2 discloses a wireless communication intelligent building control system, it is through setting up video control module in central processing module one end, security protection alarm module, entrance guard's module, building talkback module, fire alarm module, public broadcast module and network monitoring module come to carry out intelligent control to intelligent building, in order to solve current intelligent building and have not carried out intelligent control to a great deal of setting yet, lead to intelligent building control system not comprehensive, and informatization and intelligent degree is lower, when taking place emergency, there is the problem of certain potential safety hazard.
The existing intelligent building control system rarely pays attention to the problem of local network interruption when a fire disaster happens. In fact, when a fire occurs, especially when an electric fire occurs, it is necessary to first cut off a non-fire-fighting power supply to prevent causing a larger fire accident (a short circuit is broken in a fire, causing a wider range of fire accidents) and an electric shock accident (in fire rescue, water is the most commonly used fire extinguishing agent, and water is conductive), which leads to a situation that when many fire accidents occur, the accident site is often in a power failure and network breaking, and then the intelligent security facility is nearly paralyzed, for example, after a household distribution box is powered off, equipment working by means of a household wifi network cannot upload real-time data of the fire to the network. The existing intelligent building control system also adopts wireless networks such as GPRS, 3G/4G/5G and the like for communication, for example, an Aqara smoke alarm with a built-in telecommunication NB-loT card released by millet companies can realize remote alarm when power failure and network disconnection occur, but due to intensive buildings, after the conventional wifi network and the like are disconnected, a plurality of indoor situations with bad wireless communication networks exist, so that data cannot be fed back or cannot be fed back in time, the spread of fire disasters is caused, the rescue of personnel and property is delayed, and the alarm has a single function, and other emergency treatment in the case of fire disasters cannot be realized. In addition, after the fire is out of control, when rescuing the stranded personnel, the firefighters cannot timely master the positions of the stranded personnel, which is also a great problem in the fire fighting of the existing buildings.
Therefore, there is a need for further improvements to existing intelligent building control systems.

when one of the alarm groups detects a fire signal, the central processing unit corresponding to the alarm group obtains the fire signal, sends an instruction to the alarm group 1 which detects the fire signal, and starts a second communication unit of each alarm 2 in the alarm group, so that each alarm 2 in the alarm group is respectively in communication connection with at least one other alarm 2 in the alarm group through a second communication mode, and establishes data communication and fire signal sharing of full coverage in the alarm group, namely, the alarm which detects the fire signal in each alarm 2 in the alarm group can transmit the fire signal detected by the alarm to at least one other alarm in the alarm group, and the at least one other alarm can further transmit the fire signal to other alarms in the alarm group, and finally all the alarms in the alarm group obtain the fire signal; each alarm 2 in the group is respectively in communication connection with the cloud server, and after the fire signal is obtained, each alarm 2 in the group respectively uploads the fire signal to the cloud server; the cloud server performs duplicate removal processing on the fire signal after obtaining the fire signal, and sends a final processing result to the fire command end for fire-fighting equipment or personnel to call.
For example, in a residential building, all the alarms in one household form one alarm group, and in an office building, the alarms in one business unit (small business) or one whole floor in one floor form one alarm group. It should be noted that the second communication unit operates independently of the first communication unit, that is, even if the first communication mode is interrupted, the operation of the second communication mode and the data communication between each alarm in the group and the cloud server are not affected. The second communication unit is normally in a closed state and is only switched on when a fire signal is detected.
Preferably, the first communication mode uses an indoor existing communication network for communication, and further preferably, the indoor existing communication network is an indoor Wifi wireless communication network.

Preferably, the second communication unit includes at least two kinds of communication modules, be remote communication module and near field communication module respectively, and remote communication module is used for realizing the wireless network communication of alarm and cloud server, for example adopts communication modes such as GPRS, CDMA, 4G, 5G, and the near field communication module is preferably bluetooth communication module or zigBee communication module for realize the communication connection between each alarm 2 in the group and between corresponding alarm group and the adjacent alarm group. When the second communication unit is turned on, the long-range communication module and the short-range communication module are simultaneously turned on.
Further preferably, when one of the alarm groups detects a fire signal, the alarm group that detects the fire signal is also in communication connection with an adjacent alarm group (for example, the alarm group of an adjacent household, an upstairs household, or a downstairs household on the same floor) in a second communication manner (only that at least one alarm of the adjacent alarm group is in communication connection with at least one alarm of the alarm group that detects the fire signal), so as to implement data communication and fire signal sharing, and wherein the adjacent alarm group uploads the fire signal to the cloud server after obtaining the fire signal. The advantage of doing so is that, when the conflagration breaks out, the family of the resident that catches fire or the office of enterprise has cut off the power supply and has leaded to disconnected net (for example, the router of Wifi network can only work with the help of supplying power, will lead to Wifi function to close after the outage), but upstairs or downstairs do not necessarily cut off the network this moment, can directly utilize the central processing unit of adjacent alarm group to carry out data upload at this moment, and avoided adopting communication modes such as unstable GPRS, CDMA, 4G or 5G, because, some mobile communication networks of upstairs such as GPRS, CDMA, 4G or 5G's communication signal can be very weak, even lead to that each alarm of the group has all obtained fire signal, nevertheless can not upload to the high in the clouds server.
Preferably, the electric well equipment is located upstream of the electric distribution box and used for cutting off power supply to the electric distribution box; the distribution box is a power supply system terminal distribution box, and is a household distribution box when the building of a living community is reached. Considering that the electric well is far away from the indoor of a user and a wireless network cannot cover the electric well, the signal control line is adopted for electric well communication.
Preferably, after the second communication unit is turned on, each alarm can also establish communication with a handheld mobile device terminal within a certain range (for example, a bluetooth signal coverage range) through the near field communication module, and obtain a motion state parameter of the handheld mobile device terminal, the micro control unit processes the obtained initial state parameter to obtain a handheld mobile device terminal processing parameter, the handheld mobile device terminal processing parameter is processed together with a fire signal and is uploaded to the cloud server, and the fire signal includes a smoke concentration change parameter detected by the smoke sensor, a temperature change parameter detected by the temperature sensor, and coding information of the alarm initially obtaining the two parameters.
Preferably, the motion state parameters include an acceleration dynamic change parameter and an angle dynamic change parameter of the handheld mobile device terminal, and RSSI values of signals between the respective alarms 2 and the handheld mobile device terminal; the handheld mobile device terminal processing parameters comprise position information of the handheld mobile device terminal, and the position information is determined according to the RSSI value. The alarm is communicated with the handheld mobile equipment terminal, the position of the handheld mobile equipment terminal is determined, so that accurate positioning of fire rescue can be achieved, the position is reflected through the motion state of the mobile phone, if trapped people appear in a fire, the trapped people can send out a distress signal through swinging the handheld mobile equipment terminal after the communication is established between the trapped people and the alarm, and therefore the danger that dense smoke is sucked due to loud calling when the fire occurs is reduced.
Preferably, the central processing unit records position information of each alarm 2 corresponding to the central processing unit, and after the central processing unit obtains a fire signal, the central processing unit can determine the fire position according to the source of the fire signal and send an instruction for closing a switch of the distribution box or closing electric well equipment. If the indoor distribution box is on fire, the electric well equipment is closed; and if the rest parts catch fire, closing the switch of the indoor distribution box.
Preferably, when one of the alarm groups detects a fire signal, the central processing unit corresponding to the alarm group plans an escape route according to the fire signal after obtaining the fire signal, and the door on the escape route is automatically opened by using the access control system. The detection of a fire signal by one alarm group means that at least one alarm 2 in the alarm group detects a fire signal.
