when one of the alarm groups detects a fire signal, the central processing unit corresponding to the alarm group obtains the fire signal, and sends an instruction to the alarm group 1 which detects the fire signal, and the second communication unit of each alarm 2 in the group is started, so that each alarm 2 in the group is respectively in communication connection with at least one other alarm 2 in the group through a second communication mode, and data communication and fire signal sharing which are all covered in the group are established, namely, the alarm which detects the fire signal in each alarm 2 in the group can transmit the fire signal detected by the alarm to at least one other alarm in the group, and the at least one other alarm can further transmit the fire signal to the other alarms in the group, so that all the alarms in the group finally 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 de-duplication processing on the fire signals after obtaining the fire signals, and sends the final processing result to the fire command end for the fire equipment or personnel to call.
The alarm groups are illustratively divided in units of users, for example, in residential communities, where all alarms in one household form one alarm group, in office communities, where alarms in one business entity (small business) in one floor or one entire 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 and the cloud server in the group are not affected. The second communication unit is normally in an off state and is turned on only when a fire signal is detected.
Preferably, the first communication mode adopts an indoor existing communication network for communication, and more preferably, the indoor existing communication network is an indoor Wifi wireless communication network. The wired connection is not generally adopted, and the wired connection has high cost, is easy to damage, and also easily causes poor appearance, complicated wiring and the like.
Preferably, the second communication unit includes at least two communication modules, namely a long-distance communication module and a short-distance communication module, wherein the long-distance communication module is used for realizing wireless network communication between the alarm and the cloud server, for example, communication modes such as GPRS, CDMA, 4G, 5G and the like are adopted, and the short-distance communication module is preferably a Bluetooth communication module or a ZigBee communication module and is used for realizing communication connection between each alarm 2 in a group and between a corresponding alarm group and an adjacent alarm group.

This has the advantage that in case of fire, the home of the resident on fire or the office of the enterprise is already powered off and causes a disconnection (for example, the router of the Wifi network needs to work by means of power supply, and the Wifi function is turned off after power failure), but the network is not necessarily disconnected up or down, and the central processing units of the adjacent alarm groups can be directly utilized to upload data, so that unstable communication modes such as GPRS, CDMA, 4G or 5G are avoided, because the communication signals of the mobile communication network of some buildings such as GPRS, CDMA, 4G or 5G may be weak, and even if each alarm in the group obtains a fire signal, the communication signals cannot be uploaded to the cloud server.
Preferably, the electrical well equipment is located upstream of the distribution box and is used for cutting off power supply to the distribution box; the distribution box is a terminal distribution box of a power supply system, and is a household distribution box when the terminal distribution box is specific to a building of a living community. The wireless network cannot cover the well, so the signal control line is adopted for well communication, in consideration of the fact that the well is far away from the indoor space of the user.
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 (such as a bluetooth signal coverage area) through the close range communication module, and acquire a motion state parameter of the handheld mobile device terminal, and the micro control unit processes the acquired initial state parameter to obtain a handheld mobile device terminal processing parameter, where the handheld mobile device terminal processing parameter is processed along with a fire signal and uploaded to the cloud server, and the fire signal includes a smoke concentration variation parameter detected by a smoke sensor, a temperature variation parameter detected by a temperature sensor, and coding information of the alarm that initially acquires the two parameters.
Preferably, the motion state parameters include acceleration dynamic change parameters and angle dynamic change parameters of the handheld mobile equipment terminal, and signal RSSI values between each alarm 2 and the handheld mobile equipment terminal; the handheld mobile device terminal processing parameters include location information of the handheld mobile device terminal, which is determined according to the RSSI values described above. The alarm is used for communicating with the handheld mobile equipment terminal to determine the position of the handheld mobile equipment terminal, so that the accurate positioning of fire rescue can be realized, the position is reflected through the motion state of the mobile phone, if trapped personnel appear in a fire disaster, the trapped personnel can send out a distress signal by swinging the handheld mobile equipment terminal after establishing communication with the alarm, and the danger of sucking dense smoke due to loud calling when the fire disaster occurs is reduced.
Preferably, the central processing unit records the position information of each alarm 2 corresponding to the central processing unit, and after the central processing unit obtains the fire signal, the central processing unit can determine the ignition position according to the source of the fire signal and send out 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; if the other parts catch fire, the switch of the indoor distribution box is closed.
Preferably, when one of the alarm groups detects a fire signal, the central processing unit corresponding to the alarm group also plans an escape route according to the fire signal after obtaining the fire signal, and automatically opens a door on the escape route by using the access control system. The detection of the fire signal by the alarm set means that the fire signal is detected by at least one alarm 2 in the alarm set.

the method is characterized by comprising the following steps of:
step S1, equipment installation:
in a building, each resident or each floor is provided with a set of alarm groups, each alarm group is correspondingly provided with a central processing unit, a set of access control system, a distribution box and a well equipment, each alarm group respectively comprises a plurality of alarms, and the alarms are distributed in each room of the resident or the floor; when the alarm devices are arranged, communication connection in a second communication mode can be established between the alarm devices in the same alarm device group;
step S2, initializing equipment:
starting a second communication unit in each alarm, coding each alarm, wherein the alarms in the same alarm group have the same group code but different address codes, initializing and pairing the alarms, setting each alarm and at least one other alarm in the same surrounding group as default pairing equipment, enabling each paired alarm to establish data communication and fire signal sharing with full coverage in the group, and closing the second communication unit after pairing is completed;
step S3, fire signal sharing:
each alarm device collects smoke and temperature data of the environment in real time, when one alarm device detects a fire signal, the alarm device which detects the fire signal sends out alarm reminding through an alarm module, meanwhile, a central processing unit corresponding to the alarm device obtains the fire signal, sends an instruction to an alarm device group where the alarm device which detects the fire signal is located, starts a second communication unit of each alarm device in the group to pair, and establishes data communication and fire signal sharing which are all covered in the group; then, the central processing unit corresponding to the central processing unit sends the group code and the address code of the alarm device for detecting the fire signal to the cloud server through the upper computer, meanwhile, a distribution box switch is disconnected or corresponding electric well equipment is directly disconnected according to address code information, a power supply is cut off, and the first communication mode is interrupted;
step S4, uploading the cloud server:
the second communication unit continues to work, and the alarm sets for detecting the fire signals acquire the fire signals under the condition that the data communication and the fire signal sharing of the full coverage in the sets are established, and then the alarm sets are respectively connected with the cloud server through the communication between the remote communication modules and the cloud server, and upload the fire signals to the cloud server; meanwhile, each alarm establishes communication with a handheld mobile device terminal in a certain range through a close-range communication module, and obtains a motion state parameter of the handheld mobile device terminal, a micro control unit processes the obtained initial state parameter to obtain a handheld mobile device terminal processing parameter, and the handheld mobile device terminal processing parameter is processed along with a fire signal and uploaded to a cloud server;
step S5, fire rescue:
the cloud server reminds fire departments, and the fire departments execute rescue schemes according to fire signals and handheld mobile equipment terminal processing parameters which are acquired by the server terminals;
in step S2, when initializing and pairing the alarms, further pairing at least one alarm in the alarm groups with at least one alarm in the adjacent alarm groups, so that in the fire signal sharing, the alarm groups detecting the fire signal share the fire signal to the adjacent alarm groups, and uploading fire signal data by using the central processing units of the adjacent alarm groups;
according to the method, fire signals are shared and uploaded to the cloud server between the alarms in the group and between the alarm group and the adjacent alarm group under the condition of power failure and network disconnection;
when the central processing unit corresponding to the alarm set is used for processing fire signals, if the fire position is determined to be the distribution box according to the group code and the address code corresponding to the fire signals, the electric well equipment corresponding to the fire position is directly closed.
