[0064] Step S104: Send the warning information packet to the third device through short-range communication connection.

[0065] The warning method provided by the embodiment of the present invention can be applied to the first device. Refer to Figure 2 , which shows a schematic flowchart of the transmission of a warning information packet provided by the embodiment of the present invention. As Figure 2 shown, the first device is used to receive the warning information packet sent by the second device. The first device can establish a short-range communication connection with the second device through a wireless communication module. The third device is any device within the coverage range of the wireless communication module of the first device. The short-range communication connection in the present invention can include a WiFi connection or a Bluetooth connection.

[0066] In the embodiment of the present invention, during the warning process, a short-range communication connection is established between multiple devices through the wireless communication module, that is, the first device establishes a short-range communication connection with the second device through the wireless communication module; after detecting the third device within the coverage range of the wireless communication module, a short-range communication connection is established with the third device, and then the warning coverage range can be expanded through multiple short-range communication connections, so that the timely dissemination of the warning information packet can be realized without a network.

[0067] Exemplarily, the first device in the embodiment of the present invention can first establish a short-range communication connection with the second device through the wireless communication module.

[0068] Among them, the first device can be any device that receives the warning information packet. The first device is configured with a wireless communication module.

[0069] Exemplarily, the first device can be a device of the intelligent control type, such as a smart speaker, a smart central control screen, a smart camera, a smart door lock, a smart sensor, etc.

[0070] Exemplarily, the smart sensor can include a door and window sensor, a smoke sensor, a water immersion sensor, etc., which can monitor the opening and closing state of doors and windows, the smoke concentration, the water leakage situation, etc. For example, a certain brand of door and window sensor will send a notification to the mobile phone in time when the door or window is opened.

[0071] The wireless communication module can include a Bluetooth module or a WiFi module, etc., which are electronic components that can realize wireless data transmission and communication functions.

[0072] The composition of the wireless communication module can include a radio frequency chip, an antenna, a microcontroller (Microcontroller Unit, MCU), a memory, and a power management module.

[0073] Among them, the RF chip is responsible for the transmission and reception of wireless signals. The antenna is used for transmitting and receiving wireless signals. The MCU is responsible for processing data and executing communication protocols. The memory is used for storing firmware and configuration information. The power management module is used for managing the power consumption of the module.

[0074] Exemplarily, the functions of the wireless communication module may include, but are not limited to, device interconnection, remote control, data transmission, status monitoring, etc.

[0075] Among them, device interconnection refers to realizing communication between smart home devices; remote control refers to remotely controlling devices through a mobile phone APP or a cloud platform; data transmission refers to transmitting sensor data, control instructions, etc. Status monitoring refers to real-time monitoring of device status (such as temperature, humidity, switch status).

[0076] The wireless communication module is a core component of smart home devices, responsible for realizing wireless connection and data transmission between devices. According to the requirements and application scenarios of the devices, appropriate wireless communication technologies (such as Wi-Fi, Zigbee, Z-Wave, etc.) can be selected. Understanding the working principle and characteristics of the wireless communication module helps to better design and optimize smart home systems.

[0077] The second device can be any sending device on the warning information packet transmission link, not limited to the first sending device. The second device can also be a certain sending device in the middle of the transmission link.

[0078] As an example, in the case of the A->B->C->D transmission link, the second device can be device A, or it can be device B or device C.

[0079] Short-range communication connection refers to a communication method that realizes data transmission and information interaction between devices within a relatively short distance range.

[0080] Exemplarily, short-range communication connections may include Bluetooth, Wi-Fi, Zigbee, Near Field Communication (NFC), Dedicated Short Range Communication (DSRC), etc.

[0081] Among them, Bluetooth is a radio technology that supports short-distance communication between devices. It operates in the 2.4GHz frequency band. Generally, the transmission distance is about 10 meters. It can realize the connection between devices such as mobile phones, headphones, speakers, smart watches, etc., and is used for transmitting information such as audio and data. For example, using a Bluetooth headset to connect to a mobile phone to answer calls or play music.

[0082] Wi-Fi is commonly used in places such as homes, offices, shopping malls, etc., enabling devices to connect to the Internet or local area network wirelessly. Generally, the indoor coverage range is within dozens of meters. For example, mobile phones and computers can connect to a wireless router via Wi-Fi to achieve high-speed Internet access.

[0083] Zigbee is mainly used for low-rate, low-power, and low-cost wireless communication applications, such as the connection between devices like light controls, temperature sensors, and door and window sensors in smart homes. The transmission distance is generally between 10 and 100 meters, and it can form star, tree, or mesh networks.

[0084] NFC operates at a frequency of 13.56 MHz, and the communication distance is generally within a few centimeters. It is often used in mobile payment, bus card swiping, quick pairing between devices, etc. For example, a mobile phone supporting NFC can be brought close to a bus card reader or payment terminal to complete the payment.

[0085] DSRC is mainly used in the field of intelligent transportation, such as communication between vehicle-to-vehicle (V2V) and vehicle-to-infrastructure (V2I). It can achieve functions such as toll-free passing without stopping and vehicle safety warning. The working frequency band is generally 5.8 GHz, and the communication distance can reach hundreds of meters.

[0086] Exemplarily, short-range communication connections can be achieved through technologies such as Bluetooth or WiFi.

[0087] After establishing a short-range communication connection with the second device through the wireless communication module, the first device can also receive a warning information packet sent by the second device through the short-range communication connection; the warning information packet is generated by the second device based on the detected disaster information.

[0088] Among them, the warning information packet can be generated based on the detected disaster information.

[0089] Exemplarily, a detection module can be installed on smart home devices, such as a fire detector (such as a smoke sensor), a gas leakage detector, an earthquake sensor, etc.

[0090] Exemplarily, in the case where the smoke sensor detects smoke, it can be pre-judged whether it is caused by a fire. In the case of an alarm that is not caused by a fire, information about the misjudgment can be fed back.

[0091] Exemplarily, the warning information packet can include the detected disaster content, disaster level, location information, number of transmissions, etc.

[0092] Exemplarily, the disaster content can include natural disasters such as earthquake disasters, fires, floods, etc.

[0093] The disaster level can be the obtained earthquake magnitude. The positioning information can include the longitude and latitude information of the occurrence of the disaster. The way to obtain the longitude and latitude information is through positioning by the Global Positioning System (GPS) or by obtaining the Internet Protocol Address (IP). The number of transmissions is used to indicate the number of times the warning information packet is transmitted.

[0094] Exemplarily, basic parameters of seismic waves, seismic source information, etc. can be obtained through seismic sensors.

[0095] The basic parameters of seismic waves can include information such as vibration amplitude, frequency, direction, etc.

[0096] The vibration amplitude is used to reflect the magnitude of earthquake energy. The larger the vibration amplitude, the greater the energy released by the earthquake usually is, and there is a certain correlation with the earthquake magnitude. Seismic waves of different frequencies carry different information. Low-frequency seismic waves may be related to deep crustal activities, and high-frequency seismic waves may be related to the vibration characteristics of shallow strata. According to the propagation direction and vibration direction of seismic waves, it helps to judge the azimuth of the seismic source and the propagation direction of earthquake rupture.

[0097] The seismic source information can include magnitude, seismic source location, etc. Among them, the magnitude can be calculated based on parameters such as the amplitude and frequency of seismic waves, combined with seismological formulas and algorithms, to measure the size and intensity of the earthquake. The seismic source location can determine the three-dimensional coordinates of the seismic source, that is, longitude, latitude, and depth, by using information such as the time difference and propagation speed of seismic waves received by multiple seismic sensors and the principle of triangulation positioning.

[0098] After receiving the warning information packet sent by the second device through a short-range communication connection, the first device can also detect a third device within the coverage of the wireless communication module and establish a short-range communication connection with the third device.

[0099] Among them, the third device within the coverage of the wireless communication module can be any device that is connected to the same WiFi as the first device, or any device that can establish a Bluetooth connection with the first device.

[0100] After detecting the third device within the coverage of the wireless communication module and establishing a short-range communication connection with the third device, the first device can also send the warning information packet to the third device through the short-range communication connection.

[0101] Exemplarily, in the case of the transmission link of A->B->C->D, the third device can be device C or device D.

[0102] Exemplarily, during the transmission from Device A to Devices B, C, and D, the third device can be Device B or Device C, or it can also be Device D.

[0103] An embodiment of the present invention provides an early warning method. The first device can establish a short-range communication connection with the second device through a wireless communication module; receive an early warning information packet sent by the second device through the short-range communication connection; the early warning information packet is generated by the second device according to the detected disaster information; detect a third device within the coverage range of the wireless communication module and establish a short-range communication connection with the third device; and send the early warning information packet to the third device through the short-range communication connection. During the early warning process, short-range communication connections are established among multiple devices through the wireless communication module, that is, the first device establishes a short-range communication connection with the second device through the wireless communication module; after detecting a third device within the coverage range of the wireless communication module and establishing a short-range communication connection with the third device, the early warning coverage range can be expanded through multiple short-range communication connections, so that the timely dissemination of the early warning information packet can be achieved without a network.

[0104] In the embodiment of the present invention, after sending the early warning information packet to the third device through the short-range communication connection, the following steps can be specifically included:

[0105] Step S105: Determine the location information of the first device;

[0106] Step S106: Send the location information to the cloud server so that the cloud server can determine the early warning coverage range according to the location information of each device that has received the early warning information packet.

[0107] For the early warning method provided by the embodiment of the present invention, after sending the early warning information packet to the third device through the short-range communication connection, the location information of each device can be sent to the cloud server, so that the cloud server can determine the early warning coverage range according to the location information of each device.

[0108] Determine the location information of the first device.

[0109] Among them, the location information can be the longitude and latitude information of the first device, which can be obtained through GPS positioning or through the IP address.

[0110] After determining the location information of the first device, the first device can also send the location information to the cloud server so that the cloud server can determine the early warning coverage range according to the location information of each device that has received the early warning information packet.

[0111] Among them, the cloud server is used to process the location information of each device and then determine the early warning coverage range.

[0112] Exemplarily, a cloud server is a virtual server based on cloud computing technology, also known as a cloud computing server or a cloud host.

[0113] A cloud server (Elastic Compute Service, ECS) is a simple, efficient, secure, and reliable computing service with elastic scalability in processing power. Users can quickly create or release any number of cloud servers without having to purchase hardware in advance, and can access computing resources on demand like using resources such as water and electricity. The management method is simpler and more efficient than that of physical servers.

[0114] Through virtualization technology, a cloud server integrates a large number of physical server resources to form a huge resource pool. Then, according to the needs of users, virtual servers of different specifications are divided from this resource pool and allocated to each user for use. Each virtual server can independently run an operating system and application programs, and is isolated from each other, just like an independent physical server.

[0115] Cloud servers can be deployed in data centers around the world. Users can choose to deploy cloud servers in different regions according to their business needs and user distribution to achieve global coverage of their business and reduce the latency of user access.

[0116] The early warning coverage area refers to the area covered after the early warning information packet is propagated through a short-range communication connection.

[0117] Exemplarily, the early warning coverage area can be a coverage area with a radius of one kilometer centered on the disaster occurrence location, or a coverage area with a straight-line transmission distance of two kilometers centered on the disaster occurrence location, etc.

[0118] In the embodiment of the present invention, detecting a third device within the coverage area of the detection wireless communication module specifically may include the following steps:

[0119] Step S1031: Determine a preset number of propagation times according to the disaster level parameter in the early warning information packet;

[0120] Step S1032: Each time the early warning information packet is sent to a third device, increment the propagation times of the early warning information packet by 1; the initial value of the propagation times is 0;

[0121] Step S1033: Stop sending the early warning information packet when the propagation times is greater than or equal to the preset number of propagation times.

[0122] Determine a preset number of propagation times according to the disaster level parameter in the early warning information packet.

[0123] Among them, the disaster level parameter in the early warning information packet can be a first-level fire, or a second-level fire, etc.

[0124] The preset number of transmissions can be dynamically adjusted according to the disaster level parameter. When the disaster level parameter is relatively low, the determined preset number of transmissions is correspondingly small; when the disaster level parameter is relatively high, the preset number of transmissions is correspondingly large.

[0125] Exemplarily, when the disaster level parameter is a first-level fire, the determined preset number of transmissions can be 5 times; when the disaster level parameter is a second-level fire, the determined preset number of transmissions can be 10 times, etc.

[0126] After determining the preset number of transmissions according to the disaster level parameter in the warning information packet, each time the first device sends the warning information packet to a third device, the transmission count of the warning information packet is incremented by 1; the initial value of the transmission count is 0.

[0127] Exemplarily, in a scenario where a device transmits warning data packets to multiple devices, the initial value of the transmission count is set to 0. For example, if device A transmits warning information packets to devices B, C, and D, the transmission count of the warning information packet can be obtained as 3.

[0128] After incrementing the transmission count of the warning information packet by 1 each time the warning information packet is sent to a third device and the initial value of the transmission count is 0, the first device can also stop sending the warning information packet when the transmission count is greater than or equal to the preset number of transmissions.

[0129] Exemplarily, in a scenario where a device transmits warning data packets to multiple devices, when the disaster level parameter is a second-level fire, the determined preset number of transmissions is 10 times, and the transmission count of the obtained warning information packet is 11, that is, the transmission count is greater than the preset number of transmissions, then the sending of the warning information packet can be stopped.

[0130] In the embodiments of the present invention, detecting third devices within the coverage of the detection wireless communication module may specifically include the following steps:

[0131] Step S1034: Determine the preset number of transmissions according to the disaster level parameter in the warning information packet;

[0132] Step S1035: Read the preset parameter from the warning information packet; the preset parameter is used to indicate the transmission count of the warning information packet;

[0133] Step S1036: When receiving the warning information packet, increment the preset parameter by 1 and add the updated preset parameter to the warning information packet;

[0134] Step S1037: Stop sending the warning information packet when the updated preset parameter is greater than or equal to the preset number of transmissions.

[0135] Determine a preset number of transmissions according to the disaster level parameter in the warning information packet; read a preset parameter from the warning information packet; the preset parameter is used to indicate the number of transmissions of the warning information packet.

[0136] Wherein, the preset parameter refers to the actual number of transmissions of the warning information packet.

[0137] After reading the preset parameter from the warning information packet, when the first device receives the warning information packet, it can also increment the preset parameter by 1 and add the updated preset parameter to the warning information packet.

[0138] Exemplarily, in the case of the A->B->C->D transmission link, after A->B, the preset parameter will be incremented by 1, that is, the preset parameter at this time is 1, and the preset parameter = 1 is added to the warning information packet. Then, after B->C, on the basis of the preset parameter = 1, it will be incremented by 1 again, that is, the preset parameter at this time is 2. After C->D, on the basis of the preset parameter = 2, the preset parameter will be incremented by 1 again, that is, the preset parameter at this time is 3.

[0139] When the first device receives the warning information packet, after incrementing the preset parameter by 1 and adding the updated preset parameter to the warning information packet, the first device can stop sending the warning information packet when the updated preset parameter is greater than or equal to the preset number of transmissions.

[0140] Exemplarily, in the case of the A->B->C->D transmission link, when the preset number of transmissions is 3 and the updated preset parameter is 3, stop sending the warning information packet.

[0141] In the embodiment of the present invention, detecting a third device within the coverage of the wireless communication module specifically may include the following steps:

[0142] Step S1038: Centering on the first device, search for a third device with the wireless communication function enabled within the coverage of the wireless communication module; or,

[0143] Step S1039: Search for a third device that accesses the same wireless communication network as the first device.

[0144] Centering on the first device, search for a third device with the wireless communication function enabled within the coverage of the wireless communication module.

[0145] Wherein, the third device with the wireless communication function enabled refers to any device with the Bluetooth function enabled within the coverage of the wireless communication module.

[0146] Exemplarily, the third device with the wireless communication function enabled may include one device or multiple devices.

[0147] During the process of detecting a third device within the coverage range of the wireless communication module, the first device may also search for a third device that is connected to the same wireless communication network as the first device.

[0148] Among them, the third device that is connected to the same wireless communication network as the first device refers to any device that is connected to the same WiFi as the first device.

[0149] In the embodiment of the present invention, detecting a third device within the coverage range of the wireless communication module may specifically include the following steps:

[0150] Step S1040: Determine whether the warning information packet is the same as the content of at least one historical warning information packet stored locally in the first device;

[0151] Step S1041: When the warning information packet is different from the content of at least one historical warning information packet stored locally in the first device, detect a third device within the coverage range of the wireless communication module.

[0152] Determine whether the warning information packet is the same as the content of at least one historical warning information packet stored locally in the first device.

[0153] Exemplarily, when the warning information packet is exactly the same as at least one historical warning information packet stored locally in the first device, the warning information packet will be discarded. When the warning information packet is different from at least one historical warning information packet stored locally in the first device, it is necessary to detect a third device within the coverage range of the wireless communication module.

[0154] It should be noted that the first device can compare the warning information packet with at least one historical warning information packet stored locally in the first device one by one, and then can determine whether to discard the warning data packet or detect a third device within the coverage range of the wireless communication module.

[0155] In the embodiment of the present invention, the warning method may specifically include the following steps:

[0156] Step S105: Analyze the warning content in the warning information packet;

[0157] Step S106: Display the warning content through a display module and give a voice prompt through a broadcast module.

[0158] Analyze the warning content in the warning information packet.

[0159] Exemplarily, the first device can analyze the warning content in the warning information packet, that is, determine the disaster content, disaster level, location information, number of transmissions, etc. according to the warning information packet.

[0160] After parsing the warning content in the warning information packet, the first device can also display the warning content through a display module and give a voice prompt through a broadcast module.

[0161] Exemplarily, displaying the warning content can include displaying it in text or displaying it through a video, etc.

[0162] Exemplarily, during the warning prompt, it can be a text prompt or a voice prompt, etc.

[0163] In another embodiment of the present invention, the warning method can also be applied to a second device, which specifically may include the following steps:

[0164] Step S107: Generate a warning information packet according to the detected disaster information;

[0165] Step S108: Establish a short-range communication connection with the first device through a wireless communication module;

[0166] Step S109: Send the warning information packet to the first device through the short-range communication connection.

[0167] In the embodiment of the present invention, during the warning process, a short-range communication connection is established between multiple devices through a wireless communication module, that is, a short-range communication connection is established between the first device and the second device through the wireless communication module; after detecting a third device within the coverage of the wireless communication module, a short-range communication connection is established with the third device, and thus the warning coverage range can be expanded through multiple short-range communication connections, so that the timely dissemination of the warning information packet can be achieved without a network.

[0168] Generate a warning information packet according to the detected disaster information.

[0169] Among them, the warning information packet is generated by the second device according to the detected disaster information.

[0170] After generating the warning information packet according to the detected disaster information, the second device can establish a short-range communication connection with the first device through a wireless communication module.

[0171] Exemplarily, the second device in the embodiment of the present invention can first establish a short-range communication connection with the first device through a wireless communication module.

[0172] The second device can be any sending device on the warning information packet transmission link, not limited to the first sending device, and the second device can also be a certain sending device in the middle of the transmission link.

[0173] Among them, the first device can be any device that receives the warning information packet. A wireless communication module is configured in the first device.

[0174] The wireless communication module can include a Bluetooth module or a WiFi module, etc., which are electronic components that can implement wireless data transmission and communication functions.

[0175] As an example, in the case of the transmission link of A->B->C->D, the second device can be device A, or device B or device C.

[0176] After establishing a short-range communication connection with the first device through the wireless communication module, the second device can send the warning information packet to the first device through the short-range communication connection.

[0177] Among them, the short-range communication connection refers to a communication method that realizes data transmission and information interaction between devices within a relatively short distance range.

[0178] Exemplarily, the short-range communication connection can be realized through Bluetooth technology or WiFi, etc.

[0179] Send the warning information packet to the first device through the short-range communication connection.

[0180] In another embodiment of the present invention, the warning method may specifically include the following steps:

[0181] Step S110: Search for the first device with the wireless communication function enabled within the coverage of the wireless communication module with the second device as the center; or,

[0182] Step S111: Search for the first device that is connected to the same wireless communication network as the second device.

[0183] Search for the first device with the wireless communication function enabled within the coverage of the wireless communication module with the second device as the center.

[0184] Among them, the first device with the wireless communication function enabled refers to any device that enables the Bluetooth function within the coverage of the wireless communication module.

[0185] Exemplarily, the first device with the wireless communication function enabled can include one device or multiple devices.

[0186] During the process of determining the first device, the second device can also search for the first device that is connected to the same wireless communication network as the second device.

[0187] Among them, the first device that is connected to the same wireless communication network as the second device refers to any device that is connected to the same WiFi as the second device.

[0188] In an embodiment of the present invention, establishing a short-range communication connection with a first device through a wireless communication module may specifically include the following steps:

[0189] Step S1081: Generate a warning request and display it; the warning request is used to request confirmation of whether to send a warning information packet.

[0190] Step S1082: In the case of confirming the sending of the warning information packet, establish a short-range communication connection with the first device through the wireless communication module.

[0191] Generate a warning request and display it; the warning request is used to request confirmation of whether to send a warning information packet.

[0192] Among them, the warning request is used to request confirmation of whether to send a warning information packet, that is, for preliminary warning.

[0193] After generating a warning request and displaying it; the warning request is used to request confirmation of whether to send a warning information packet, the second device may also, in the case of confirming the sending of the warning information packet, establish a short-range communication connection with the first device through the wireless communication module.

[0194] Exemplarily, in the case of confirming the sending of the warning information packet, the second device may establish a short-range communication connection with the first device.

[0195] After the smart home device (second device) detects disaster information, it sends a warning message (warning information packet) to surrounding devices through WiFi or Bluetooth, and the devices that receive the warning then spread it to other devices to form network relay propagation.

[0196] The warning information can be broadcast by voice or displayed on devices such as mobile phones and smart bracelets.

[0197] Estimate the disaster occurrence location based on the location of the device that issues the warning.

[0198] Estimate the coverage area of the warning information based on the hop count (propagation times) of the warning information propagation and the device density.

[0199] Exemplarily, referring to Figure 3 , shows the step flow of a warning method provided by an embodiment of the present application Figure 2 , as Figure 3 shown, this method specifically includes steps S201 to S211:

[0200] Step S201: Install a disaster detection module on the smart home device.

[0201] Install a disaster detection module on the smart home device, such as a fire detector (such as a smoke sensor), a gas leakage detector, an earthquake sensor, etc., and connect these sensors to the smart home device for real-time monitoring of environmental changes.

[0202] Step S202: Detect a disaster and generate a warning information packet.

[0203] When the sensor detects an abnormality, an alarm signal is immediately sent to the device; (the second device) the device generates a warning information packet based on the alarm signal, including the disaster type, the location of the sending device, etc.

[0204] Step S203: Broadcast and send the warning information packet via WiFi / Bluetooth.

[0205] When broadcasting and sending, the MAC address of the sending device will be recorded to avoid retransmission.

[0206] Step S204: Receive the warning information packet and check whether it contains a duplicate information packet.

[0207] It is judged by comparing the unique identifier (such as a random code) in the warning information packet.

[0208] Exemplarily, in the process of judging according to the unique identifier (such as a random code) in the warning information packet, local comparison, database comparison, comparison in network communication, etc. can be carried out.

[0209] Among them, the local comparison can include hash value comparison. The hash value comparison refers to calculating the hash value of the content in the information packet (including the unique identifier) and comparing it with the expected hash value of the information packet stored locally. If the hash values are the same, it means that the content of the information packet (including the unique identifier) has not been tampered with and is the expected information packet.

[0210] Among them, the database comparison can include query matching, which means using the received unique identifier as a query condition to query in the database.

[0211] Among them, the comparison in network communication can include protocol - specified comparison. That is, in the network communication protocol, it usually stipulates how to process and verify the unique identifier. For example, in the TCP / IP protocol, data packets have specific sequence numbers and acknowledgment numbers and other identifiers. The receiving party will compare these identifiers according to the protocol rules to ensure the correctness and integrity of data transmission. When the sending party sends data, it will assign a sequence number to each data packet. After receiving the data packet, the receiving party will judge whether there is data loss or out - of - order according to the sequence number and inform the sending party of the correctly received data packets through the acknowledgment number.

[0212] Step S205: Discard the duplicate information packet.

[0213] If it is a duplicate received warning information packet, it will be discarded.

[0214] Step S206: Continue to broadcast and send the warning information packet.

[0215] If it is a new warning message, continue to broadcast and send the warning message packet.

[0216] Step S207: Within a preset range, receive the warning message packet through the devices around (the first device or the third device).

[0217] The surrounding devices keep WiFi or Bluetooth turned on and are in the broadcast listening mode; in the case of a new warning message packet, it can be broadcast and sent through WiFi or Bluetooth; the wireless module of the surrounding devices can then receive the warning message packet.

[0218] Step S208: Estimate the location where the disaster occurs.

[0219] The receiving device of (the first device or the third device) estimates the possible location where the disaster may occur based on the location of the sending device.

[0220] Step S209: Estimate the warning coverage area.

[0221] Estimate the radius of the warning coverage area based on the number of hops of warning propagation and the device density.

[0222] Step S210: Display the warning content.

[0223] The receiving device of (the first device or the third device) parses the content in the warning message packet; and displays the warning content on devices such as mobile phones, tablets, and smart bracelets.

[0224] Step S211: Play a voice warning.

[0225] Broadcast a warning voice prompt through a speaker or a voice broadcast module.

[0226] Exemplarily, two-factor authentication can also be used to avoid false alarms. First, send a preliminary warning and require the user to confirm or cancel; after the user confirms, then conduct a full warning sending and display.
