After pairing is completed, the Bluetooth processor stores the MAC addresses of all the wireless peripheral devices that are successfully paired with itself, and the Bluetooth processor also performs fault detection on all the wireless peripheral devices that are successfully paired with itself; After pairing is completed, the wireless peripheral device stores the MAC address of the Bluetooth processor, and then sets its own broadcast to directional broadcast, so that its own broadcast packet is only received by the Bluetooth processor that has been successfully paired with itself.

[0007] As a preferred technical solution of the present invention, the Bluetooth processor and multiple wireless peripheral devices establish a Bluetooth connection, including the following steps: The Bluetooth processor obtains the Bluetooth device information of the wireless peripheral device, compares the Bluetooth device information with the protocol information pre-stored in the protocol database, and when the protocol information matching the Bluetooth device information is found, the Bluetooth processor actively sends a test instruction to the wireless peripheral device for verification, and when the return information of the wireless peripheral device can be received, the matching protocol information is used to communicate with the wireless peripheral device, and when the protocol information matching the Bluetooth device information cannot be found, the Bluetooth processor sends the Bluetooth device information to the mobile phone APP, searches for the protocol information matching the Bluetooth information device through the mobile phone APP, and adds the found protocol information matching the Bluetooth device information to the protocol database, and uses the matching protocol information to communicate with the wireless peripheral device, and when the protocol information matching the Bluetooth device information cannot be found through the mobile phone APP, the general protocol information is used to communicate with the wireless peripheral device.

The wireless peripheral device sends the second data to the Bluetooth processor, and the Bluetooth processor determines whether the first data and the second data are the same. If they are the same, the wireless peripheral device sends a handshake confirmation message to the wireless peripheral device. If they are not the same, the wireless peripheral device does not send a handshake confirmation message.

BRIEF DESCRIPTION OF THE DRAWINGS

[0016] Figure 1 A flowchart of the steps of the wireless device control method for a home alarm of the present invention; Figure 2 The figure is a structural diagram of the wireless device control device for a household alarm according to the present invention. DETAILED DESCRIPTION

[0017] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0018] It is understood that the terms "first", "second", etc. used in this application may be used herein to describe various elements, but unless otherwise specified, these elements are not limited by these terms. These terms are only used to distinguish a first element from another element. For example, without departing from the scope of this application, a first xx script may be referred to as a second xx script, and similarly, a second xx script may be referred to as a first xx script.

[0019] The present invention provides Figure 1 The wireless device control method for a home alarm is implemented by executing the following steps: Step S1: Use sensors to collect various gas concentrations in the target environment, and transmit the collected gas concentrations to a Bluetooth processor.

[0020] Specifically, in order to obtain the concentrations of various gases in the environment and determine whether the gas concentration in the environment exceeds the concentration threshold through concentration information, a gas sensor is set in the target area where gas is used, generally in the kitchen and other areas, to collect the concentrations of various gases in the target environment and transmit the collected gas concentrations to the Bluetooth processor.

[0021] Step S2, the Bluetooth processor obtains the gas concentration collected by the sensor, and compares the gas concentration with a preset concentration threshold. When the gas concentration is greater than the concentration threshold, an audible and visual alarm is issued through the audible and visual device, the audible and visual device includes a fault indicator light and a buzzer, and also generates alarm information and generates verification information based on the alarm information. The Bluetooth processor establishes a Bluetooth connection with multiple wireless peripheral devices, and sends alarm information and verification information to multiple wireless peripheral devices through the Bluetooth connection. After the alarm information is sent, the Bluetooth processor and the wireless peripheral device disconnect the Bluetooth connection, and the Bluetooth processor also sends the alarm information to the mobile phone APP.

[0022] Specifically, after the Bluetooth processor obtains the gas concentration, it determines whether the gas concentration in the environment exceeds the preset concentration threshold. If it exceeds, the Bluetooth processor enters the alarm mode, controls the buzzer to sound, and controls the indicator light to flash to alarm. By issuing an audible and visual alarm, the user is reminded to take safety measures. After that, the Bluetooth processor also establishes a Bluetooth connection with multiple wireless peripheral devices, and the multiple wireless peripheral devices include Bluetooth solenoid valves, Bluetooth manipulators, Bluetooth gas meters, etc. The Bluetooth processor generates an alarm message and sends the alarm message to multiple wireless peripheral devices. The wireless peripheral devices perform corresponding operations based on the alarm message, such as closing the gas valve, cutting off the gas port, etc. In order to ensure the correctness of the alarm message sent by the Bluetooth processor, prevent data from being tampered with, and ensure that the wireless peripheral device receives the correct alarm message, thereby ensuring that the wireless peripheral device can perform the correct operation, the Bluetooth processor also generates verification information based on the alarm message, and sends the alarm message and the verification message to the wireless peripheral device together. After the alarm message is sent, the Bluetooth processor and the wireless peripheral device disconnect the Bluetooth connection to ensure that the wireless peripheral device can operate with low power consumption. The Bluetooth processor also sends the alarm message to the mobile phone APP to ensure that the user can obtain the alarm message in time according to the mobile phone APP when the user is not at home.

[0023] Step S3: After receiving the alarm information and the verification information, the wireless peripheral device verifies the alarm information based on the verification information to obtain a verification result, and determines whether the received alarm information is normal based on the verification result. If normal, a corresponding operation is performed based on the alarm information.

[0024] Specifically, in order to ensure that the wireless peripheral device can perform correct operations based on the alarm information, after the wireless peripheral device receives the alarm information and verification information, the wireless peripheral device uses the method of generating verification information with the Bluetooth processor to generate a second verification information based on the received alarm information. If the generated second verification information is the same as the received verification information, it means that there is no error in the transmission of the alarm information, and the wireless peripheral device performs corresponding operations based on the alarm information. For example, the Bluetooth solenoid valve closes the gas valve based on the alarm information, the Bluetooth manipulator closes the gas port based on the alarm information, and the Bluetooth gas meter closes the gas meter based on the alarm information. If they are not the same, it means that there is an error in the transmission of the alarm information. The alarm information is abnormal, and the user or relevant staff can be notified to take corresponding inspection measures.

[0025] Through the above method, the Bluetooth processor and the wireless peripheral device are connected using Bluetooth wireless communication technology, so that multiple wireless peripheral devices can be controlled by one Bluetooth processor. In a large space environment with multiple gas valve nodes, the installation point is flexible and the construction is convenient. When sending alarm information to control the wireless peripheral device, verification information is also generated through the alarm information to ensure that the alarm information is not tampered with during the transmission process. At the same time, it also ensures that the wireless peripheral device can make correct operations according to the alarm information, such as timely cutting off the gas supply when a gas leak occurs.

[0026] Furthermore, after the Bluetooth processor performs the sound and light alarm, the following steps are also performed: The Bluetooth processor determines whether it has been paired with the wireless peripheral device by determining whether the MAC address of the wireless peripheral device is stored in the memory space. If it has been paired, the Bluetooth processor establishes Bluetooth links with multiple wireless peripheral devices in sequence according to the MAC addresses of the wireless peripheral devices stored in advance, and sends alarm information to the wireless peripheral devices through the Bluetooth connection. If it has not been paired, the Bluetooth processor and the wireless peripheral device enter the pairing process for pairing. After the pairing is completed, the Bluetooth links are established in sequence with the multiple paired wireless peripheral devices according to the MAC addresses, and the alarm information is sent to the wireless peripheral devices through the Bluetooth connection.

[0027] Specifically, when a gas leak or other dangerous situation is detected, in order to be able to quickly and effectively notify and trigger relevant safety measures, the Bluetooth processor needs to send an alarm message to the wireless peripheral device after the sound and light alarm is issued. Before sending the alarm message to the wireless peripheral device, it is necessary to establish a Bluetooth connection with the wireless peripheral device. First, determine whether the MAC address of the wireless peripheral device is stored in the memory space. If the MAC address is stored, it means that it has been paired with the wireless peripheral device before. A Bluetooth connection is established directly with the wireless peripheral device through the MAC address, and an alarm message is sent through the Bluetooth connection. If the wireless peripheral device is not stored, it means that the Bluetooth processor has not been paired with the wireless peripheral device. At this time, it is necessary to display the wireless peripheral device to enter the pairing process for pairing. After the pairing is completed, a Bluetooth connection is established with the paired wireless peripheral device based on the MAC address, and an alarm message is sent to the wireless peripheral device through the Bluetooth connection. Through the above steps, the alarm message can be sent to the wireless peripheral device in a timely manner.

[0028] Furthermore, the Bluetooth processor and the wireless peripheral device enter a pairing process for pairing, including the following steps: The wireless peripheral device transmits broadcast packets at preset time intervals. During the period of sending the broadcast packets, the Bluetooth chip of the wireless peripheral device turns on the radio frequency function to transmit the broadcast. The wireless peripheral device also adds its own device information to the broadcast packet. The Bluetooth processor obtains the device information of the wireless peripheral device through the broadcast packet. The device information includes the device identification code, Bluetooth broadcast name, MAC address, solenoid valve connection status and device power information.

[0029] Specifically, as a Bluetooth slave device, the wireless peripheral device must be discovered by the host before it can be connected to the host, which refers to the Bluetooth processor. The wireless peripheral device continuously broadcasts Bluetooth to the outside, which will keep the efficiency of the wireless peripheral device in a high state. Therefore, the wireless peripheral device will regularly broadcast Bluetooth to the outside, such as transmitting a Bluetooth broadcast every 2 seconds, to reduce the average power consumption of the wireless peripheral device and increase the usage time of the wireless peripheral device. In order to quickly pair with the Bluetooth processor, the wireless peripheral device adds its own device information to the broadcast packet and sends it out in the form of broadcast, so that after the Bluetooth processor receives the broadcast packet, it can quickly pair and connect with the wireless processor based on the content of the broadcast packet.

[0030] The Bluetooth processor continuously scans the surrounding wireless peripheral devices that can be paired and obtains the broadcast packets of the wireless peripheral devices, obtains the Bluetooth broadcast name and AMC address through the broadcast packets, identifies the wireless peripheral devices through the Bluetooth broadcast name and MAC address, and after continuously scanning for a preset first time period, sorts the wireless peripheral devices according to the Bluetooth signal strength based on the scanning results, sends handshake connection instructions to the wireless peripheral devices in sequence according to the sorting, and authenticates each other with the wireless peripheral devices at the same time. After the authentication is successful, a handshake is performed to confirm that the pairing is completed. After the pairing is completed, the Bluetooth processor stores the MAC addresses of all wireless peripheral devices that have been successfully paired with itself. The Bluetooth processor also performs fault detection on all wireless peripheral devices that have been successfully paired with itself.

[0031] Specifically, the Bluetooth processor is generally powered by AC power, and there is no need to consider the problem of power consumption. The Bluetooth processor can continuously scan the surrounding wireless peripheral devices that can be paired. After scanning the broadcast packet of the wireless peripheral device, the Bluetooth broadcast name and MAC address are obtained based on the broadcast packet to identify the corresponding wireless peripheral device. After the first duration of continuous scanning, such as 10 seconds of continuous scanning, multiple wireless peripheral devices may be scanned. The wireless peripheral devices are sorted based on the Bluetooth signal strength of the multiple wireless peripheral devices, and handshake instructions are sent to the wireless peripheral devices in sequence. There may be Bluetooth devices in the environment that are not for gas alarm. In order to remove interference and enable the wireless peripheral device and the Bluetooth processor to pair with each other, it is necessary to verify the legitimacy of each other. Therefore, the Bluetooth processor and the wireless peripheral device perform mutual verification. The specific verification process will be explained later. After the verification is successful, the pairing is confirmed to be completed. After the pairing is completed, the Bluetooth processor also stores the MAC addresses of all wireless peripheral devices that have been successfully paired with itself. Since the wireless peripheral device may fail, such as running out of power, in order to obtain the status of the wireless peripheral device in time, the Bluetooth processor also performs fault detection on all wireless peripheral devices that have been successfully paired with itself. The specific fault detection method will be explained later.

[0032] After pairing is completed, the wireless peripheral device stores the MAC address of the Bluetooth processor, and then sets its own broadcast to directional broadcast so that its own broadcast packet is only received by the Bluetooth processor that has been successfully paired with itself.

[0033] Specifically, considering the privacy of data and the interference of other devices, after pairing is completed, the wireless peripheral device stores the MAC address of the Bluetooth processor that has successfully paired with itself, and then sets its own broadcast to directional broadcast so that its own broadcast packet is only received by the Bluetooth processor that has been successfully paired with itself.

[0034] Furthermore, the Bluetooth processor also performs fault detection on all wireless peripheral devices paired with itself, including the following steps: After scanning the broadcast packet sent by the wireless peripheral device, the Bluetooth processor sets a timer with a preset second duration. If a broadcast packet from the wireless peripheral device is received within the second duration, the timer is restarted. If no broadcast packet from the corresponding wireless peripheral device is received within the second duration, it is determined that the wireless peripheral device has a fault, and an audible and visual alarm is issued through the audible and visual equipment, and the fault information is also sent to the mobile phone APP connected to the Bluetooth processor.

[0035] Specifically, in the event of a failure of a wireless peripheral device, the wireless peripheral device may not be able to send broadcast packets outward. At this time, the Bluetooth processor cannot scan the wireless peripheral device. Based on this principle, the Bluetooth processor performs fault detection on the wireless peripheral device. After the Bluetooth processor scans the broadcast packet sent by the wireless peripheral device, it is assumed that the wireless peripheral device sends broadcast packets outward in sequence every 2 seconds. Considering that other interference may cause the loss of broadcast packets, a 30-second timer can be set. If the broadcast packet of the corresponding wireless peripheral device is received within 30 seconds, it means that the wireless peripheral device is in a normal state. At this time, the timer is reset and restarted. If the broadcast packet of the corresponding wireless peripheral device is not received within 30 seconds, it means that the wireless peripheral device has failed. The Bluetooth processor sends an audible and visual alarm through an audible and visual device. In order to distinguish it from other abnormal situations, different sounds and lights can be set for different fault types when issuing an audible and visual alarm, so that users can judge the fault type conveniently. After that, the Bluetooth processor also sends the fault information to the mobile phone APP connected to itself, so that users can view the specific fault information through the mobile phone APP and take effective troubleshooting and maintenance measures accordingly.

[0036] Furthermore, the Bluetooth processor and the plurality of wireless peripheral devices establish a Bluetooth connection, comprising the following steps: The Bluetooth processor obtains the Bluetooth device information of the wireless peripheral device, compares the Bluetooth device information with the protocol information pre-stored in the protocol database, and when the protocol information matching the Bluetooth device information is found, the Bluetooth processor actively sends a test instruction to the wireless peripheral device for verification, and when the return information of the wireless peripheral device can be received, the matching protocol information is used to communicate with the wireless peripheral device, and when the protocol information matching the Bluetooth device information cannot be found, the Bluetooth device information is sent to the mobile phone APP, and the protocol information matching the Bluetooth information device is searched through the mobile phone APP, and the found protocol information matching the Bluetooth device information is added to the protocol database, and the matching protocol information is used to communicate with the wireless peripheral device, and when the protocol information matching the Bluetooth device information cannot be found through the mobile phone APP, the general protocol information is used to communicate with the wireless peripheral device.

[0037] Specifically, different wireless peripheral devices have different functions due to different manufacturers, and usually the protocols they use cannot be fully compatible. If different software programs are developed for different wireless peripheral devices, it will not only greatly increase the workload, but also be detrimental to product upgrades and maintenance. Therefore, the present invention proposes a protocol adaptation method. After establishing a connection with the wireless peripheral device, the Bluetooth device information is first obtained. The Bluetooth device information includes the manufacturer name, device model, device model, firmware revision version, etc. of the wireless peripheral device. The Bluetooth device information is compared with the protocol information pre-stored in the protocol database. The protocol information refers to the communication protocol between the Bluetooth processor and the wireless peripheral device, including alarm instructions, alarm recovery instructions, and self-test instructions. The protocol information of different manufacturers is pre-stored in the database and matched with it. The matching protocol information is obtained, and a test instruction is sent for verification. If the return information of the corresponding wireless peripheral device is received, it means that the match is successful. After that, the corresponding protocol information can be used to communicate with the wireless peripheral device. If the corresponding protocol information cannot be found in the protocol database, the Bluetooth device information is sent to the mobile phone APP, and the Bluetooth device information is uploaded to the server through the mobile phone APP. The server searches for the relevant protocol information, and adds the corresponding protocol information to the protocol database if it is found. If it cannot be found, try to use the general protocol to communicate with the wireless peripheral device. Through the above method, only one set of software code is used to regularly maintain and update the protocol data block, so that the Bluetooth processor can have stronger compatibility and can connect more wireless peripheral devices from different manufacturers.

[0038] Furthermore, mutual authentication with the wireless peripheral device includes the following steps: Generate a first arbitrary value, send the first arbitrary value to the wireless peripheral device, the wireless peripheral device generates a second arbitrary value after receiving the first arbitrary value, send the second arbitrary value to the Bluetooth processor, the Bluetooth processor generates a first password based on the first arbitrary value and the second arbitrary value, the Bluetooth processor encrypts the first data using the first password to generate first ciphertext data, and sends the first ciphertext data to the wireless peripheral device; The wireless peripheral device generates a second password based on the first arbitrary value and the second arbitrary value, and also uses the second password to decrypt the received first ciphertext data to obtain second data. The wireless peripheral device sends the second data to the Bluetooth processor, and the Bluetooth processor determines whether the first data and the second data are the same. If they are the same, a handshake confirmation message is sent to the wireless peripheral device. If they are not the same, the wireless peripheral device does not send a handshake confirmation message.

[0039] Specifically, in order to enable the Bluetooth processor and the wireless peripheral device to authenticate each other, the Bluetooth processor uses a preset first algorithm to generate a first arbitrary value and sends it to the wireless peripheral device. After receiving the first arbitrary value, the wireless peripheral device generates a second arbitrary value and sends it to the Bluetooth processor. The Bluetooth processor generates a first password based on the first arbitrary value and the second arbitrary value, and also uses the first password to encrypt the first data to generate first ciphertext data. The first data can use preset arbitrary data or randomly generate an arbitrary number. The first ciphertext data is sent to the wireless peripheral device. The wireless peripheral device generates a second password based on the first arbitrary value and the second arbitrary value, and uses the second password to decrypt the first ciphertext data to obtain the second data. The data is sent to the Bluetooth processor. After receiving the second data, the Bluetooth processor determines whether the first data and the second data are the same. If they are the same, it means that the two have been authenticated successfully and can communicate safely. The Bluetooth processor sends a handshake confirmation message to the wireless peripheral device to make the two pair successfully. If they are not the same, it means that the two have been authenticated unsuccessfully and the two may not be Bluetooth devices that need to communicate with each other. Therefore, the Bluetooth processor does not send a handshake confirmation message to the wireless peripheral device, making the pairing of the two unsuccessful. The above method can ensure safe and interference-free communication between the Bluetooth processor and the corresponding wireless peripheral device, avoid connecting to other wireless peripheral devices that are not related to the gas alarm, and avoid interference with the transmission of alarm information by other devices when gas leaks.

[0040] Further, generating a first arbitrary value comprises the following steps: Obtain a predetermined number of storage spaces, set initial storage values ​​of all storage spaces to be empty, obtain a first storage address of a first storage space, obtain a timestamp of a current time, obtain a number of bits of the timestamp as a first operation value, add the first operation value and the first storage address to generate a first operation value, and use the first operation value as a first storage value of the first storage space; Obtain a second storage address of the second storage space, perform an XOR operation on the first storage value and the second storage address to obtain a second operation value, use the second operation value as the second storage value of the second storage space, and repeat this step to set corresponding storage values ​​for the remaining storage spaces; Calculate the first arbitrary value R using the first formula, the first formula is R=HN % 2 M , where HN is the storage value of the last storage space, and M is the number of binary digits of the first arbitrary value to be generated; Use the first arbitrary value and several bits of the current timestamp to add to obtain a new calculation value, perform an XOR operation on the new calculation value and the storage value of the last storage space, update the obtained result as the first storage value of the first storage space, use the storage value of the previous storage space and the storage value of the current storage space to perform an XOR operation and use the obtained result as the new storage value to update the storage value of the current storage space.

[0041] Specifically, the predetermined number is set to a value greater than or equal to five, for example, the predetermined number is set to five, the initial storage value of all storage spaces is set to null, the storage address of the storage space is generally an eight-digit hexadecimal number, for example, the storage address of the first storage space is 0x12345678, and several bits of the timestamp of the current time are obtained, for example, the last four bits of the timestamp are obtained, assuming that the last four bits are 1234, then the first storage value of the first storage space is 0x12345678+1234=0x12356AB2, the storage address of the second storage space is obtained, assuming that it is 0x00112233, and the second storage value of the second storage space is 0x00112233 XOR 0x12356AB2=0x124688C5, the second storage value and the storage address of the third storage space are XORed to obtain the third storage value of the third storage space, and the storage values ​​corresponding to the subsequent storage spaces are subsequently generated in the same way. After calculating the storage values ​​of all storage spaces, the first arbitrary value is calculated using the above-mentioned first formula, where M can control the size of the generated first arbitrary value. Then, the generated first arbitrary value and several bits of the current timestamp are added to obtain a new operation value, and the new operation value and the storage value of the last storage space are XORed and the obtained result is used as the storage value of the first storage space, so as to achieve the purpose of updating the storage value of the first storage space. Then, the storage value of the first storage space and the current storage value of the second storage space are XORed and the obtained result is used as the new storage value of the second storage space, so as to achieve the purpose of updating the storage value of the second storage space. The storage values ​​of all other storage spaces are updated using the same method to prepare for the next generation of the first arbitrary value.

[0042] Further, generating a second arbitrary value comprises the following steps: A first value is defined, a plurality of first numbers greater than zero and less than or equal to the first value are randomly generated, the plurality of first numbers are combined into a first data set, the number of first numbers in the first data set is the first value, and the first numbers in the first data set are numbered from one; Define the initial value as 1, randomly generate a second number that is less than or equal to the first value, obtain the first number numbered as the second number in the first data set, add the first number to the second data set, increase the initial value by 1, and repeat this step until the initial value is the first value; All second numbers in the second data set are obtained, and all second numbers are combined together in order to form a second arbitrary value.

[0043] Specifically, in the process of mutual authentication, in order to prevent the outside world from easily obtaining the method of mutual authentication between the Bluetooth processor and the wireless peripheral device, the above method is used to generate an efficient and complex second arbitrary value, so that the generation of the second arbitrary value is more flexible and the randomness is improved, and the generated second arbitrary values ​​are unpredictable and independent. The arbitrary value generated by the above method can make the generated second arbitrary value random, and two completely identical arbitrary values ​​cannot be easily generated.

[0044] Further, generating verification information based on the alarm information includes the following steps: Use the first conversion method to convert the alarm information into the first information, determine whether the number of bits of the alarm information and the first information are the same, if they are the same, convert the alarm information and the first information into binary data, perform an XOR operation on the converted alarm information and the first information to obtain the second information, sum all the bits of the second information to obtain the sum result, and use the sum result as verification information.

[0045] Specifically, in order to enable the wireless peripheral device to receive correct alarm information, make correct control operations according to the alarm information, generate verification information based on the alarm information, and enable the wireless peripheral device to determine whether there is an error in the transmission of the alarm information based on the verification information, first use the first conversion method to convert the alarm information into the first information. The first conversion method can be a hash function, that is, the alarm information is converted into the first information through the hash function, and then the alarm information and the first information are converted into binary data. It is also determined whether the number of bits of the two converted binary numbers is the same. In different situations, for example, the number of bits of the alarm information is less than that of the first information, 0 is added after the alarm information to make the number of bits of the alarm information the same as that of the first information, and the two are XORed to obtain the second information, all the bits of the second information are summed to obtain the sum result, and the sum result is used as verification information. The verification information and the alarm information are sent to the wireless peripheral device. By generating verification information through the above complex method, it is possible to avoid matching the error pattern of the data with the calculation method of the verification information, thereby improving the error detection rate of the wireless peripheral device.

[0046] Further, verifying the alarm information based on the verification information to obtain a verification result includes the following steps: The wireless peripheral device generates second verification information based on the received alarm information using the same method as the Bluetooth processor to generate verification information, and determines whether the second verification information is the same as the received alarm information. If they are the same, the alarm information is determined to be normal; if not, the alarm information is determined to be abnormal.

[0047] Specifically, the wireless peripheral device uses the method of generating verification information with the Bluetooth processor to generate second verification information based on the received alarm information. If the generated second verification information is the same as the received verification information, it means that there is no error in the transmission of the alarm information. The wireless peripheral device takes corresponding measures based on the alarm information, such as closing the gas valve. If they are not the same, it means that there is an error in the transmission of the alarm information. The alarm information is abnormal, and the user or relevant staff can be notified to take corresponding inspection measures.

The Bluetooth processor establishes a Bluetooth connection with multiple wireless peripheral devices, and sends alarm information and verification information to multiple wireless peripheral devices through the Bluetooth connection. After the alarm information is sent, the Bluetooth processor and the wireless peripheral device disconnect the Bluetooth connection, and the Bluetooth processor also sends the alarm information to the mobile phone APP; The wireless peripheral module is used to verify the alarm information based on the verification information to obtain a verification result after receiving the alarm information and verification information, and to determine whether the received alarm information is normal based on the verification result. If it is normal, perform corresponding operations based on the alarm information.
