Description

Technical Field

[0001] The present invention relates to the technical field of smart door locks, and in particular to a multifunctional smart door lock and a control method thereof. Background Art

[0002] With the advancement of technology and the improvement of people's living standards, there is an increasing demand for multifunctional smart door locks. However, current smart door locks are generally used only for door unlocking and unlocking, specifically for personal identification, and suffer from a single function. Furthermore, for frequent natural disasters such as earthquakes and fires, as well as indoor water and gas leaks, there are a variety of disaster warning systems on the market. However, these systems are often independent and not integrated into a single smart home device. Furthermore, they are rarely integrated into smart door locks that can automatically open doors in an emergency. Furthermore, if an indoor gas leak, such as coal or natural gas, or a large-scale water leak, occurs, it can easily lead to disasters such as fires or floods, seriously endangering not only the personal safety of those inside but also other household appliances. For example, if a smart door lock is damaged and cannot open the door in time, people inside may be trapped, potentially resulting in significant casualties and property damage. Therefore, there is an urgent need for a multifunctional smart door lock that can effectively warn of various indoor hazards to protect the lives and property of family members.

[0045] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without making creative efforts shall fall within the scope of protection of the present invention.

[0046] In this embodiment, a multifunctional smart door lock is provided. The smart door lock is installed on the door body. Figure 1 FIG is a structural diagram of a multifunctional intelligent door lock according to an embodiment of the present invention. Figure 1 As shown, the smart door lock includes: a main control module 1 and a detection module 2 and an exhaust module 3 respectively connected thereto, wherein the main control module 1 is arranged inside the door lock, the exhaust module 3 connects the inner door part and the outer door part of the door lock, and the detection module 2 is arranged in the inner door part of the door lock.

[0047] In this embodiment, the detection module 2 is used to obtain indoor environment data and send the indoor environment data to the main control module 1.

[0048] It should be noted that the specific content of the indoor environment data in this embodiment is not limited here, and is adaptively adjusted according to the actual detection function of the smart door lock. For example, for the gas detection function of the smart door lock, the corresponding indoor environment data includes different types of gases, such as carbon monoxide, which is only used as an example.

[0049] In this embodiment, the main control module 1 is used to analyze indoor environment data to generate corresponding control instructions, control the smart door lock to perform early warning processing based on the control instructions, or send the control instructions to the exhaust module 3.

[0050] It should be noted that the exhaust module 3 in this embodiment is mainly used to promote air exchange between indoor and outdoor. For example, when the indoor harmful gas content or smoke concentration exceeds the corresponding warning threshold, the indoor gas can be discharged to the outside through the exhaust module 3; or fresh air can be introduced from the outside into the room to reduce the indoor harmful gas content or smoke concentration.

[0051] In this embodiment, the exhaust module 3 is configured to perform an exhaust operation based on the control instruction after receiving the control instruction, so as to exhaust the indoor air to the outside or introduce the outdoor air into the room.

[0052] The multifunctional smart door lock of the embodiment of the present invention is designed to include a main control module and a detection module and an exhaust module respectively connected thereto to provide effective early warning of various dangerous situations indoors. Specifically, the detection module obtains indoor environmental data and sends it to the main control module. The main control module analyzes the received indoor environmental data and generates corresponding control instructions to control the smart door lock or the exhaust module accordingly. It can effectively detect and timely warn of various potential dangers indoors, which not only enriches the various detection functions of the smart door lock, but also greatly protects the life and property safety of people, and meets the efficient and safe use requirements of the smart door lock.

[0053] In this embodiment, a multifunctional intelligent door lock system is provided. The intelligent door lock is installed on the door body. Figure 2 FIG is a schematic diagram of the structure of another multifunctional smart door lock according to an embodiment of the present invention.Figure 2 As shown, the multifunctional smart door lock system of this embodiment also includes an ejection module 4 arranged inside the door of the door lock, which is used to receive the control instructions sent by the main control module, and after receiving the control instructions, unlock the smart door lock, and perform an inflation operation based on the control instructions to open the door body.

[0054] It should be noted that, in this embodiment, unlocking the smart door lock is used to represent that the lock body is automatically opened, but at this time the door body is still in a closed state and needs to be manually pushed open by a person. Therefore, an ejection module 4 is designed to eject the door body on which the smart door lock is installed in dangerous situations to achieve automatic outward opening of the door body. The specific content of the ejection module 4 is not limited here and can be adaptively adjusted according to actual needs. For example, if the ejection module 4 is designed as an airbag, the airbag is inflated to expand it, thereby generating a corresponding thrust on the door body to achieve the purpose of automatically pushing the door body outward.

[0055] The multifunctional smart door lock of the embodiment of the present invention is also designed with an ejection module and its corresponding door lock control process, which can open the door in time when various dangerous situations occur indoors, thereby effectively ensuring the safety of people's lives.

[0056] In this embodiment, if Figure 2 As shown, the exhaust module 3 includes a fan 31, a motor 32 and an exhaust duct 33, wherein the two ports of the exhaust duct 33 are respectively a first air outlet and a second air outlet, the first air outlet is arranged at the inner door part of the door lock, and the second air outlet is arranged at the outer door part of the door lock; the motor 32 is used to drive the fan 31 to rotate, generate corresponding wind force, and drive the indoor gas to flow into the first air outlet of the exhaust duct 33 and be discharged from the second air outlet based on the wind force, or drive the outdoor gas to flow into the second air outlet of the exhaust duct and be discharged from the first air outlet based on the wind force.

[0057] It should be noted that the specific types of the fan 31, motor 32 and exhaust duct 33 in this embodiment can be determined according to actual needs and are not limited in detail here. For example, the exhaust duct 33 is a high-temperature and high-pressure resistant hose.

[0058] In the embodiment of the present invention, an exhaust module including a fan, a motor and an exhaust duct is designed, which can perform timely and automatic exhaust treatment when indoor gas such as coal gas or natural gas leaks. This is of great significance to family safety and greatly ensures the safety of people and property.

[0059] In this embodiment, see Figure 2 The ejection module 4 includes a gas generator 41 and an airbag 42, wherein the gas generator 41 is used to generate gas and fill it into the airbag 42, so that the airbag 42 is inflated and deployed, generating corresponding thrust, and pushing the door body to open based on the thrust.

[0060] It should be noted that the inflator plays a crucial role in airbags. Its primary function is to ignite the combustible in the inflator in the event of an abnormality, such as a vehicle collision, releasing a large amount of heat. This ignites the oxidant and nitrogen in a chemical reaction, producing a large amount of nitrogen that rapidly fills the airbag, thereby protecting passengers. The operating principles of the inflator 41 and airbag 42 in this embodiment are similar and can be found in the preceding text. These details will not be repeated here.

[0061] In the embodiment of the present invention, an ejection module including a gas generator and an airbag is designed, which can automatically eject the door of the smart door lock when a serious danger occurs indoors, thereby avoiding the situation where people are trapped due to being unable to open the door, facilitating timely escape of people, and greatly ensuring the safety of people's lives.

[0062] In this embodiment, the smart door lock includes a home safety monitoring function, which detects anomalies or provides early warnings for indoor environmental data, including at least multiple gas types, smoke, temperature, humidity, and seismic data. Specifically, by designing a home safety monitoring function that includes anomaly detection for multiple gas types, smoke, and other types, as well as early warnings for multiple disaster types, it comprehensively covers all potential indoor hazards, significantly enriching the door lock's detection capabilities and enabling flexible and effective early warnings for various indoor hazards, thereby ensuring personal safety.

[0063] It should be noted that the smart door lock in this embodiment has a gas detection function and a disaster warning function, and the corresponding functions are enabled and configured through a mobile terminal that interacts with the smart door lock. Among them, the gas detection function is used to perform abnormal detection on smoke and various gas types, and the disaster warning function is used to perform warning processing on various disaster types.

[0064] It should be noted that the specific contents of the gas types and disaster types in this embodiment are not limited in detail. For example, the gas types include harmful gases such as methane and carbon monoxide; the disaster types include gas leaks, fires, etc., which are only used as examples.

[0065] In the embodiment of the present invention, a gas detection function including abnormal detection of multiple gas types and a disaster warning function for early warning processing of multiple disaster types are designed, and flexible function settings are performed through a mobile terminal that interacts with the smart door lock. It can not only comprehensively cover various potential dangers indoors, thereby enriching the detection function of the door lock, but also realize flexible and effective early warning of various dangerous situations indoors, greatly protecting the lives and property of people.

[0066] In this embodiment, the workflow of the smart door lock for detecting anomalies in indoor environment data includes:

[0067] a detection module 2 configured to acquire environmental quality data in an indoor environment and send the environmental quality data to the main control module 1, wherein the environmental quality data comprises smoke and different types of gas and corresponding gas content;

[0068] the main control module 1 configured to determine a size relationship between the environmental quality data and a corresponding preset quality threshold to obtain a corresponding determination result, generate a corresponding control instruction based on the determination result, and perform early warning processing on the smart door lock based on the control instruction, or send the control instruction to the exhaust module 3 or the ejection module 4, so that the exhaust module 3 performs an exhaust operation after receiving the control instruction or the ejection module 4 opens the door body after receiving the control instruction; wherein if the environmental quality data is greater than a corresponding first preset quality threshold and less than a corresponding second preset quality threshold, a first control instruction is generated, and the smart door lock is controlled to perform voice broadcast based on the first control instruction; if the environmental quality data is greater than the corresponding second preset quality threshold and less than a corresponding third preset quality threshold, a second control instruction is generated and sent to the exhaust module 3, for controlling the exhaust module 3 to perform an exhaust operation to promote air exchange between indoor and outdoor; if the environmental quality data is greater than the corresponding third preset quality threshold, a third control instruction is generated and sent to the ejection module 4, for unlocking the smart door lock and controlling the ejection module 4 to perform an inflation operation to open the door body.

[0069] It should be noted that the corresponding values of the first preset quality threshold, the second preset quality threshold and the third preset quality threshold in the embodiment are not limited in detail herein and can be adaptively adjusted according to the actual gas type; in addition, the specific content of the voice broadcast of the smart door lock in the embodiment can also be adaptively set according to actual needs, such as broadcasting content "There is gas leakage, please pay attention!" or controlling the horn of the smart door lock to emit a "beep" warning sound.

[0070] In a specific embodiment, when the gas detection function is turned on, the working process of the smart door lock includes:

[0071] the detection module 2 configured to acquire smoke concentration or gas content of a corresponding type of gas in an indoor environment based on a configured smoke or gas type in response to a mobile terminal turning on a gas detection function, and send the smoke concentration or gas content to the main control module 1; the main control module 1 configured to determine a size relationship between the smoke concentration and a preset concentration threshold or the gas content and a preset content threshold to obtain a corresponding determination result; generate a corresponding control instruction based on the determination result, and perform early warning processing on the smart door lock based on the control instruction, or send the control instruction to the exhaust module 3 or the ejection module 4, so that the exhaust module 3 exhausts indoor gas to the outdoor after receiving the control instruction or the ejection module 4 opens the door body after receiving the control instruction.

[0072] It should be noted that, in this embodiment, the relationship between the gas content and the preset content threshold is taken as an example for detailed explanation, specifically: if the gas content is greater than the first preset content threshold and less than the second preset content threshold, a first control instruction is generated, and the smart door lock is controlled to perform voice broadcast based on the first control instruction; if the gas content is greater than the second preset content threshold and less than the third preset content threshold, a second control instruction is generated and sent to the exhaust module 3, for controlling the exhaust module 3 to perform the exhaust operation; if the gas content is greater than the third preset content threshold, a third control instruction is generated and sent to the ejection module 4, for unlocking the smart door lock and controlling the ejection module 4 to perform the inflation operation.

[0073] It should be noted that the corresponding values ​​of the first preset content threshold, the second preset content threshold and the third preset content threshold in this embodiment are not limited in detail here, and can be adaptively adjusted according to the actual gas type; in addition, the determination process of the relationship between the smoke concentration and the preset concentration threshold in this embodiment can be found in the relevant content above, and will not be repeated here.

[0074] In the embodiment of the present invention, after the gas detection function is configured through the mobile terminal, the detection module is used to obtain the gas content corresponding to the function and send it to the main control module, so that the main control module generates corresponding control instructions based on the size relationship between the gas content and the set different preset content thresholds, and then controls the operation of the smart door lock, exhaust module or ejection module according to the generated control instructions. When various types of gases leak indoors, they can be graded and processed according to the leakage situation, which helps to ensure family safety.

[0075] In this embodiment, when the disaster warning function is turned on, the workflow of the smart door lock performing warning processing on indoor environment data includes:

[0076] The detection module 2 is used to obtain target data corresponding to at least one disaster type and send all target data to the main control module 1; the main control module 1 is used to respectively judge the size relationship between each target data and the corresponding preset data threshold to obtain the corresponding judgment result; based on all the judgment results, a corresponding early warning instruction is generated, and the smart door lock is early warned based on the early warning instruction, or the early warning instruction is sent to the ejection module 4 so that the ejection module 4 opens the door body after receiving the early warning instruction; wherein, if there is at least one target data greater than the first data threshold and less than the second data threshold, a first early warning instruction is generated, and the smart door lock is controlled to perform voice broadcast based on the first early warning instruction; if there is at least one target data greater than the second data threshold, a second early warning instruction is generated and sent to the ejection module 4, which is used to unlock the smart door lock and control the ejection module 4 to perform an inflation operation to open the door body.

[0077] It should be noted that, in this embodiment, the activation of the disaster warning function is achieved by performing corresponding configuration operations on the mobile terminal; the corresponding values ​​of the first data threshold and the second data threshold are not limited in detail here, and can be adaptively adjusted according to the actual disaster type; in addition, the specific content of the voice broadcast of the smart door lock in this embodiment can also refer to the relevant content in the previous article, and will not be repeated here.

[0078] In the embodiment of the present invention, all target data corresponding to different disaster types are obtained and sent to the main control module, so that the main control module generates corresponding early warning instructions according to the size relationship between each target data and the set different preset data thresholds, and then controls the operation of the smart door lock or ejection module according to the generated early warning instructions. When different types of disasters occur indoors, they can be graded according to the actual degree of disaster, comprehensively covering effective early warnings of various potential dangers indoors, thereby greatly protecting the lives and property of people.

[0079] It should be noted that, in this embodiment, the gas types include at least methane, carbon monoxide and carbon dioxide; the disaster types include at least earthquakes, fires and floods; the detection module 2 has a built-in plurality of preset sensors, wherein the preset sensors include at least methane sensors, carbon monoxide sensors, carbon dioxide sensors, smoke sensors, earthquake sensors, temperature sensors, humidity sensors and water intrusion sensors.

[0080] It should be explained that methane sensors, also known as CH4 sensors, can obtain methane (CH4) concentrations through different types of CH4 sensors. For example, catalytic combustion sensors contain a heated catalytic bead and a thermistor. When methane gas contacts the catalytic bead, flameless combustion occurs under the action of the catalyst, generating heat. The thermistor senses the temperature increase and its resistance changes accordingly, thereby forming an electrical signal output proportional to the methane concentration. The methane concentration can actually be determined by measuring the resistance change. Carbon monoxide sensors, also known as CO sensors, determine carbon monoxide (CO) concentrations by measuring changes in current. When carbon monoxide gas molecules enter the sensor through a permeable membrane and come into contact with the surface of the sensing electrode, an electrochemical reaction occurs, generating a current. The magnitude of the current is proportional to the carbon monoxide concentration, so the CO concentration can be determined by measuring the current intensity. Carbon dioxide sensors, also known as CO2 sensors, use electrochemical reactions to detect the carbon dioxide (CO2) concentration in the environment. Specifically, when carbon dioxide molecules pass through the active material of the sensing layer, an oxidation-reduction reaction occurs, generating a current signal, thereby measuring the carbon dioxide concentration. Smoke sensors primarily monitor smoke concentration for fire prevention. They typically use photoelectric smoke detectors or ionization smoke sensors. Photoelectric smoke detectors work by emitting a light beam and detecting the scattering of light by smoke, while ionization smoke sensors use a radioactive source to generate positive and negative ions and detect the interference of smoke with charged particles. Seismic sensors measure ground vibrations and convert them into electrical signals. Accelerometers are often used to measure the intensity of seismic waves. Specifically, when an earthquake occurs, the sensor detects the propagation of seismic waves and sends a trigger signal to a data center for earthquake warning. Temperature sensors are based on the fact that the resistivity or electromotive force of a material changes with temperature. The most common temperature sensors include thermistors and thermocouples. Thermistors utilize the temperature-dependent resistivity of metals. By measuring the change in resistance, the temperature of the object being measured can be inferred. Thermocouples are based on the thermoelectric effect. When two conductors of different materials form a closed circuit, the temperature difference generates an electromotive force. The magnitude of the electromotive force is proportional to the temperature difference, and the temperature can be determined by measuring the electromotive force. Humidity sensors can detect changes in humidity in the current environment through different types of sensors. Common sensor types include resistive, capacitive, thermoelectric, surface tension, and optical. The appropriate type can be determined based on actual needs. Water sensors operate primarily based on two technologies: conductive and non-conductive. Conductive water sensors contain two electrodes. When water contacts these electrodes, a conductive path is formed, triggering the sensor to issue an alarm signal. Non-conductive sensors use optical, capacitive, or piezoelectric principles to trigger an alarm by detecting the presence of water or changes in the water level. These sensors eliminate the need for direct contact with the water, reducing the risk of failure due to corrosion.

[0081] In a specific embodiment, Figure 3 This is a schematic diagram of the structure of a multifunctional smart door lock, which has the functions of safety detection, automatic exhaust and automatic opening. Figure 3 It can be seen that the structure of the smart door lock is as follows: above the rear panel of the lock (i.e. the inner part of the door lock), it appears to contain a first air outlet and contains a detection module inside; above the front panel of the lock (i.e. the outer part of the door lock), it contains a second air outlet, and the internal structure contains a motor and a fan; the second air outlet and the first air outlet are connected by a high-temperature and high-pressure resistant hose (i.e. the exhaust duct); the middle position of the rear panel of the lock also contains an ejection module, which can quickly inflate the airbag in the module after detecting that the smoke concentration, gas content or disaster warning signal exceeds a certain threshold, so as to generate thrust to eject the door body, thereby realizing automatic opening of the door body.

[0082] In a specific embodiment, Figure 4 This is a circuit diagram of a multifunctional smart door lock. It should be noted that the smart door lock has a conventional unlocking and recognition function, which uses the recognition module and radar module to perform corresponding target person identification and identity authentication; other modules include other conventional functional modules or expansion modules of the smart door lock, such as communication module, power module, etc. Figure 4 It can be seen that the circuit includes: a radar module, an identification module, a main control module, a detection module, an exhaust module, an ejection module, and other modules, among which other modules may include a WiFi module, a Bluetooth module, a speaker module, a cat's eye module, etc. Specifically, the exhaust module includes a fan and a motor for exhausting indoor gas; the ejection module includes a gas generator and an airbag for automatically opening the door; the detection module includes a CH4 sensor, a CO sensor, a CO2 sensor, a smoke sensor (for fire detection), a seismic sensor (for earthquake detection), a temperature sensor (for fire detection), a humidity sensor (for flood detection), a water intrusion sensor (for flood detection), etc.

[0083] In the embodiment, when the detection module detects that the content or concentration of the gas (such as CH4 / CO / CO2) or smoke corresponding to the content or concentration exceeds the first threshold value, the main control module sends a signal to start the alarm signal and the push signal; when the content or concentration exceeds the second threshold value, the automatic exhaust module is started, the motor drives the fan to rotate, and the indoor gas is discharged to the outside through the hose (i.e. the exhaust pipeline); when the content or concentration exceeds the third threshold value, the lock body is automatically triggered to open first, and then the ejection module is started, i.e. a control signal is sent to the gas generator in the ejection module, so that the detonator in the gas generator is ignited to trigger a chemical reaction to generate a large amount of gas, the generated gas rapidly fills the safety airbag to make it expand in a very short time, and then the door body is rapidly pushed to open outward. When the disaster warning data (such as earthquake warning signal / fire warning signal / flood warning signal) obtained by the detection module exceeds the first threshold value, the main control module sends a signal to start the alarm signal and the push signal; when the second threshold value is exceeded, the lock body is automatically triggered to open first, and then the ejection module is started, i.e. a signal is sent to the gas generator in the ejection module, so that the detonator in the gas generator is ignited to trigger a chemical reaction to generate a large amount of gas to inflate the safety airbag; the generated gas rapidly fills the safety airbag to make it expand in a very short time, and then the door body is rapidly pushed to open outward. The flood warning signal is derived from the data obtained by the humidity sensor and the water intrusion sensor, and the corresponding warning signal is generated when the corresponding data exceeds a certain threshold value; the fire warning signal is derived from the temperature sensor, the smoke sensor and the indoor camera module (such as identifying a flame), i.e. corresponding to the different data obtained.

[0084] In the embodiment of the application, a control method for the multifunctional intelligent door lock is also provided. It should be noted that the steps shown in the flowchart can be executed in a computer system such as a set of computer executable instructions, and although the logical order is shown in the flowchart, in some cases, the steps shown or described can be executed in an order different from that shown here.

[0085] In the embodiment, a control method for the multifunctional intelligent door lock is provided, Figure 5 The flowchart of the control method for the multifunctional intelligent door lock according to the embodiment of the application is shown in FIG. 5, which includes the following steps: Figure 5 The flowchart of the control method for the multifunctional intelligent door lock according to the embodiment of the application is shown in FIG. 5, which includes the following steps:

[0086] In step S501, in response to the opening and configuration operation of the target user on the corresponding function of the home safety monitoring of the intelligent door lock, the detection module is used to obtain the corresponding indoor environment data, and the indoor environment data is sent to the main control module, wherein the intelligent door lock has a gas detection function and a disaster warning function, and the indoor environment data includes at least one type of gas, smoke, temperature, humidity and earthquake data.

[0087] In this embodiment, the corresponding contents of indoor environment data, gas detection function and disaster warning function can be found in the previous text and will not be repeated here.

[0088] In step S502, the main control module analyzes the indoor environment data to generate corresponding control instructions, controls the smart door lock to perform early warning processing based on the control instructions, or sends the control instructions to the exhaust module or the ejection module.

[0089] In this embodiment, the specific contents of the warning processing, exhaust module and ejection module of the smart door lock can be found in the previous text and will not be repeated here.

[0090] Step S503: After the exhaust module receives the control instruction, it performs an exhaust operation based on the control instruction to promote indoor and outdoor air exchange, or, after the ejection module receives the control instruction, it unlocks the smart door lock and performs an inflation operation based on the control instruction to open the door body.

[0091] It should be explained that in this embodiment, promoting indoor and outdoor air exchange is achieved through the exhaust operation of the exhaust module, which includes related operations of discharging indoor gas to the outside and introducing outdoor gas into the room. The specific content of the exhaust operation can be found in the previous text and will not be repeated here.

[0092] The control method of the multifunctional smart door lock of the embodiment of the present invention is to enable and configure the corresponding functions of the smart door lock through a mobile terminal connected to the smart door lock, and then use the detection module to obtain the corresponding indoor environment data and send it to the main control module to analyze the indoor environment data to generate corresponding control instructions, and based on the generated control instructions, the smart door lock, exhaust module or ejection module is controlled accordingly. It can effectively detect and timely warn various potential dangers in the room, greatly enrich the various detection functions of the smart door lock, while also ensuring the safety of people's lives and property, and meeting the safe use requirements of the smart door lock.

[0093] It should be noted that the smart door lock in this embodiment has a gas detection function and a disaster warning function. When different functions are enabled, the corresponding smart door lock workflow includes:

[0094] Step A1, when the gas detection function is turned on, the detection module is used to obtain the corresponding environmental quality data in the indoor environment based on the configured gas type and its corresponding gas content or smoke, and the environmental quality data is sent to the main control module; the main control module determines the size relationship between the environmental quality data and the corresponding preset quality threshold. If the environmental quality data is greater than the corresponding first preset quality threshold and less than the corresponding second preset quality threshold, a first control instruction is generated, and the smart door lock is controlled to perform voice broadcast based on the first control instruction; if the environmental quality data is greater than the corresponding second preset quality threshold and less than the corresponding third preset quality threshold, a second control instruction is generated and sent to the exhaust module for controlling the exhaust module to perform an exhaust operation to promote indoor and outdoor air exchange; if the environmental quality data is greater than the corresponding third preset quality threshold, a third control instruction is generated and sent to the ejection module for unlocking the smart door lock and controlling the ejection module to perform an inflation operation to open the door body.

[0095] Step A2, when the disaster warning function is turned on, the detection module is used to obtain the corresponding target data based on at least one configured disaster type, and all target data are sent to the main control module; the main control module respectively judges the size relationship between each target data and the corresponding preset data threshold. If there is at least one target data greater than the first data threshold and less than the second data threshold, a first warning instruction is generated, and the smart door lock is controlled to perform voice broadcast based on the first warning instruction; if there is at least one target data greater than the second data threshold, a second warning instruction is generated and sent to the ejection module, which is used to unlock the smart door lock and control the ejection module to perform an inflation operation to open the door body.

[0096] In the embodiment of the present invention, an intelligent door lock with gas detection function and disaster warning function is designed. Flexible function setting is achieved through a mobile terminal that interacts with the intelligent door lock. When different functions are turned on, the indoor environment data corresponding to the function is obtained, and the indoor environment data is analyzed to obtain corresponding control instructions to control the intelligent door lock, exhaust module or ejection module to perform corresponding work. It can comprehensively cover various potential dangers indoors, thereby enriching the detection function of the door lock, and realizing flexible and effective warning of various dangerous situations indoors, greatly protecting the lives and property safety of people, and can greatly ensure the recognition accuracy and realize precise control of the door lock body.

[0097] In a specific real-time example, the gas detection function is enabled and configured through a mobile phone APP that interacts with the smart door lock. Figure 6 This is a flow chart of the gas detection function. Figure 6 As we know, the process includes:

[0098] Step B1: The mobile phone APP sets the gas detection function; whether the lock body is allowed to open automatically when the threshold is exceeded (open by default), and whether the airbag is allowed to automatically deploy when the threshold is exceeded (open by default).

[0099] It should be noted that in this embodiment, the lock body opens automatically, that is, the door lock opens, but the door body is still in a closed state, and a person needs to manually push the door open; the airbag automatically pops open, that is, the door body pops open, at this time the door body is in an open state, the indoor gas can be directly discharged, and the people indoors can leave directly without opening or pushing the door.

[0100] Step B2: When the detection module detects that CH4 / CO / CO2 / smoke exceeds the first threshold, the door lock speaker sounds an alarm and pushes a message to the administrator.

[0101] Step B3: When the detection module detects that CH4 / CO / CO2 / smoke exceeds the second threshold, the door lock exhaust operation is started to automatically exhaust.

[0102] Step B4: When the detection module detects that CH4 / CO / CO2 / smoke exceeds the third threshold, the lock body automatically opens and the ejection module is activated to eject the door body.

[0103] In this embodiment, the automatic opening of the door body facilitates the direct discharge of gas through the door, and also facilitates the direct escape of indoor personnel, and also facilitates outdoor personnel (neighbors or property or firefighters) to seek help in time and buy time without prying the door, which can protect property safety to a certain extent.

[0104] In a specific real-time example, the disaster warning function (also known as the natural disaster detection function) is enabled and configured through a mobile phone APP that interacts with the smart door lock. Figure 7 This is a flowchart of the disaster warning function.

[0105] Depend on Figure 7 As we know, the process includes:

[0106] Step C1, the mobile phone APP sets the natural disaster detection function; whether the lock body is allowed to open automatically when the threshold is exceeded (default is open), and whether the airbag is allowed to automatically pop out when the threshold is exceeded (default is open).

[0107] In this embodiment, the relevant contents of the automatic opening of the lock body and the automatic deployment of the airbag are referred to above and will not be repeated here.

[0108] Step C2: When the detection module detects an earthquake warning signal / fire warning signal / flood warning signal, and any one of them exceeds a first threshold, the door lock speaker sounds an alarm and pushes a message to the administrator.

[0109] Step C3: When the detection module detects an earthquake warning signal / fire warning signal / flood warning signal, any one of which exceeds the second threshold, the lock body automatically opens, and the ejection module is activated to eject the door body.

[0110] The embodiment can automatically open the door body at the first time when disaster occurs, further prevent the door body from being deformed and not being opened, and facilitate the indoor personnel to directly escape and the outdoor personnel to directly rescue.

[0111] The multifunctional intelligent door lock has a plurality of advantages, and the advantages are as follows.

[0112] 1. The door lock is provided with a detection device, such as a CH4 sensor, a CO sensor, a CO2 sensor, a smoke sensor, a seismic sensor, a temperature sensor, a humidity sensor, a water intrusion sensor and the like.

[0113] 2. When the indoor environmental data exceeds a certain threshold value, the door lock can automatically alarm and push a message to the administrator of the door lock for timely processing.

[0114] 3. When the environmental quality data, such as the gas content or the smoke concentration, exceeds a certain threshold value, the door lock can automatically exhaust to avoid the harm caused by gas leakage.

[0115] 4. When the disaster warning data exceeds a certain threshold value, the door lock can automatically open the door and eject the door body, so as to facilitate the personnel to escape in time, and further greatly guarantee the personal safety.

[0116] 5. The door lock function includes the detection of man-made disasters and natural disasters, and does not need to manually open the door, but can automatically push the door, so as to facilitate the indoor personnel to escape and the outdoor personnel to rescue.

[0117] Although the embodiments of the present application are described in combination with the drawings, various modifications and variations can be made by those skilled in the art without departing from the spirit and scope of the present application, and such modifications and variations fall within the scope defined by the appended claims.
