[0037] Star flash technology: refers to a new generation of wireless short-range communication technology, which has low latency, high reliability, high speed, anti-interference, high concurrency, precise positioning, etc. compared with traditional short-range communication technology.

[0038] Narrowband Internet of Things (NB-IoT): a new technology in the field of Internet of Things, which supports low-power devices to connect to the cellular data network in a wide area network, also known as Low Power Wide Area Network (LPWAN). NB-IoT supports long standby time and high network connection requirements for efficient connection of devices.

[0039] With the continuous advancement of urban construction, the gas popularization rate continues to improve, and gas has become a widely used energy in people's life. However, gas leakage often leads to serious accidents such as fire, explosion, poisoning and the like, which poses a threat to people's life and property safety.

[0040] In the prior art, gas leakage is often detected by a gas alarm, and an alarm is given when gas leakage occurs, but when the user fails to respond in time, the gas leakage cannot be handled in time.

[0041] Based on the above technical problems, the embodiments of the present application provide an alarm system, which detects whether gas leakage occurs through an alarm, and sends alarm information to a server and at least one gas device when gas leakage occurs; the gas device performs corresponding processing operations according to the alarm information, and timely eliminates risks; the server pushes the alarm information and corresponding location information to a user terminal, so that the user can handle it in time, and therefore, the timely and reliability of gas leakage handling can be effectively improved, and the safety of gas use is ensured.

[0042] Figure 1 The structure diagram of the gas alarm system provided by the embodiments of the present application is shown in FIG. 1. Figure 1 As shown in the figure, the gas alarm system 100 includes a server 11, an alarm 12 and at least one gas device 13.

[0043] The alarm 12 is used to detect whether gas leakage occurs, and send alarm information to at least one gas device 13 and the server 11 when gas leakage occurs.

[0044] The gas device 13 is used to perform gas leakage protection operations according to the alarm information.

[0045] The server 11 is used to push the alarm information and the alarm location information corresponding to the alarm 12 to the user terminal 200.

[0046] In specific implementation, the alarm 12 can communicate with the gas device 13 in real time, obtain the real-time state of the gas device 13, and detect whether gas leakage occurs. The alarm 12 uploads the state data of the gas device 13 and itself to the server 11, so that the user can view the state of the alarm 12 and the gas device 13 through the user terminal 200. The alarm 12 timely reports the alarm information to the server 11 when gas leakage occurs, and sends the alarm information to at least one gas device 13. The alarm information can include the current gas concentration. To ensure that the gas device 13 successfully receives the alarm information, the alarm 12 can send the alarm information to the gas device 13 at a predetermined period of time until receiving the receiving notification returned by the gas device 13. The predetermined period of time can be selected according to actual needs, for example, it can be 1-255 seconds.

[0047] The alarm 12 can communicate with multiple gas devices 13, and the alarm 12 can send alarm information to the multiple gas devices 13 concurrently, and identify each gas device 13 according to device information of each gas device 13.

[0048] After the gas device 13 receives the alarm information, the gas device 13 automatically performs a pre-set gas leakage protection operation, so as to timely eliminate the risk. After the server 11 receives the alarm information, the server 11 analyzes the alarm information, and pushes alarm position information corresponding to the alarm 12 to the user terminal 200, so that the user can timely perform corresponding processing.

[0049] It can be understood that the server 11 can communicate with multiple alarms 12, wherein the positions of the alarms 12 are fixed, and each alarm 12 is provided with a unique code, so that the server 11 can determine the alarm position of the alarm 12 according to the correspondence between the code and the position of the alarm 12.

[0050] In the embodiments of the present application, the alarm is used to detect whether gas leakage occurs, and send alarm information to the server and at least one gas device when gas leakage occurs; the gas device is used to perform corresponding processing operation according to the alarm information, and timely eliminate the risk; and the server is used to push the alarm information and corresponding position information to the user terminal, so that the user can timely perform processing. Therefore, the timeliness and reliability of gas leakage processing can be effectively improved, and the safety of gas use can be ensured.

[0051] Figure 2 Another structure schematic diagram of a gas alarm system provided by the embodiments of the present application is provided. As shown in Figure 2 In a possible implementation manner, the alarm 12 includes a host star flash communication module, and the at least one gas device 13 is provided with a slave star flash communication module.

[0052] The host star flash communication module is used to send alarm information to the at least one gas device 13 using star flash technology.

[0053] The slave star flash communication module is used to receive the alarm information.

[0054] In a specific implementation, the communication between the alarm 12 and the gas equipment 13 can be realized through the star flash technology. The alarm 12 is provided with a host star flash communication module as a star flash host, the gas equipment 13 is provided with a slave star flash communication module as a star flash slave, the host star flash communication module can receive the state data of the gas equipment 13 sent by the slave star flash communication module, and the slave star flash communication module can receive the alarm information sent by the host star flash communication module. Before communication, the device numbers of the gas equipment 13 around which need to be linked and controlled are recorded in the host star flash communication module of the alarm 12, and the alarm 12 code is recorded in the slave star flash communication module, so that the star flash wireless communication can be carried out.

[0055] Figure 3 The business process schematic diagram of the star flash host (the alarm 12) provided in the embodiment of the application is shown in FIG. 2. Figure 3 As shown in FIG. 2, when no gas leakage is detected, the star flash host carries out regular data communication with the star flash slave and carries out regular data communication with the cloud server 11. When gas leakage is detected, the star flash host carries out leakage alarm to multiple star flash slaves through one-to-many communication mode, sends the alarm information to the multiple star flash slaves in parallel, and reports the alarm information to the cloud server 11.

[0056] Figure 4 The business process schematic diagram of the star flash slave (the gas equipment 13) provided in the embodiment of the application is shown in FIG. 3. Figure 4 As shown in FIG. 3, when no alarm information is received, if the star flash slave carries out regular data communication with the star flash host, the gas leakage protection operation is cancelled; when the alarm information is received, the gas leakage protection operation is executed.

[0057] The regular data communication between the star flash host and the cloud server 11 can include that the star flash host sends the slave state data to the cloud server 11, or the cloud server 11 sends the user control instruction to the star flash host. The regular data communication between the star flash host and the star flash slave can include that the star flash slave sends the slave state data to the star flash host, or the star flash host sends the user control instruction to the star flash slave.

[0058] In the embodiment of the application, the host star flash communication module and the slave star flash communication module realize the short-distance communication between the alarm and the gas equipment through the star flash technology, which is simple to install, does not need additional slot wiring, is convenient to maintain, has significantly improved coverage compared with the Bluetooth technology, has strong anti-interference ability, can support one-to-many concurrent communication between the alarm and multiple gas equipments, can timely control multiple gas equipments to respond when gas leakage occurs, can eliminate the danger, and can more reliably handle the gas leakage.

[0059] In a possible implementation, the alarm 12 further includes an NB-IoT / 4G module.

[0060] NB-IoT / 4G module, configured to send the alarm information to the server 11.

[0061] In a specific implementation, the NB-IoT / 4G module of the alarm 12 can send the state data of the gas device 13 to the cloud server 11 through the NB-IOT or 4G communication mode, and the cloud server 11 can push the state data of the gas device 13 to the user terminal 200, so that the user can remotely view the state data of the gas device 13 at home. The user can also send a control instruction on the user terminal 200, and the cloud server 11 sends the control instruction to the alarm 12 through the NB-IOT or 4G communication mode, and the alarm 12 sends the control instruction to the gas device 13 through the short-range communication mode, thereby realizing remote control of the gas device 13. When gas leakage occurs, the NB-IoT / 4G module can send the alarm information to the server 11 through the NB-IOT or 4G communication mode, thereby timely and reliably reporting the gas leakage.

[0062] In the embodiment of the application, the NB-IoT / 4G module can quickly send the alarm information to the cloud server, thereby effectively reporting the gas leakage.

[0063] In a possible implementation, the alarm 12 further includes a detection module.

[0064] The detection module is configured to detect the current gas concentration and the gas concentration change rate within a specified time, and determine that gas leakage occurs if the gas concentration belongs to an abnormal concentration range or the gas concentration change rate belongs to an abnormal change range.

[0065] In a specific implementation, the detection module of the alarm 12 detects the current gas concentration and the gas concentration change rate within a specified time, and determines whether the gas concentration belongs to an abnormal concentration range and whether the gas concentration change rate belongs to an abnormal change range, so that gas leakage can be determined when the gas concentration is abnormal or the gas concentration is abnormally high.

[0066] For example, the abnormal concentration range, the abnormal change range, and the detection period can be selected according to actual needs, for example, the abnormal concentration range can be 1-20%, the abnormal change range can be 1-20%, and the detection period can be 0-255 seconds. When the specified time is 0, it means that the gas concentration change rate is not detected. The user can remotely set parameters such as the abnormal concentration range, the abnormal change range, and the detection period on the user terminal 200, or set parameters such as the abnormal concentration range, the abnormal change range, and the detection period through local infrared.

[0067] In the embodiments of the present application, the detection module determines that gas leakage occurs when the gas concentration is abnormal or the abnormal gas concentration rises, and can accurately detect and determine the gas leakage.

[0068] Figure 5 Another structure diagram of a gas alarm system provided by the embodiments of the present application is shown in FIG. 6. Figure 5 As shown in FIG. 6, in a possible implementation, the gas equipment 13 is one of a gas meter, a converter, a valve controller, an oil smoke machine or a gas stove.

[0069] For example, when the gas equipment 13 is the valve controller,

[0070] The gas equipment 13 is configured to control the pre-stove valve to close according to the alarm information.

[0071] In a specific implementation, the valve controller is configured to control the pre-stove valve, which is installed between the gas pipe and the gas stove connecting hose, to control the gas pipe to ventilate to the gas connecting pipe and the gas stove. After receiving the alarm information, the valve controller controls the pre-stove valve to close, which can effectively avoid further gas leakage caused by gas leakage of the gas stove connecting hose or interface.

[0072] For example, when the gas equipment 13 is the gas meter,

[0073] The gas equipment 13 is configured to report the alarm information to the gas company platform and control the safety valve to close according to the alarm information.

[0074] In a specific implementation, the gas meter can upload the gas use data to the alarm 12, and upload the gas use data to the server 11 through the alarm 12, so that the user can view the gas use data on the user terminal 200. After receiving the alarm information, the gas meter reports the alarm information to the gas company platform and controls the safety valve to close.

[0075] For example, when the gas equipment 13 is the converter,

[0076] The gas equipment 13 is configured to send the alarm information to the community safety monitoring device 300 according to the alarm information.

[0077] In a specific implementation, when the converter receives the alarm information, the converter sends the alarm information to the safety monitoring device 300 of the community, so that the safety monitoring device 300 timely informs the property or community personnel to go to the site for investigation and treatment.

[0078] The converter can communicate with the community safety monitoring device 300 in a wired manner.

[0079] For example, when the gas equipment 13 is the oil smoke machine,

[0080] The gas device 13 is configured to open the exhaust according to the alarm information when the current gas concentration is within the safety range, and the alarm information includes the current gas concentration.

[0081] In specific implementations, the alarm 12 can also be connected with a window controller, and the alarm 12 sends alarm information to the window controller when gas leakage occurs, so that the window controller controls the window to open for ventilation. However, most conventional windows are not provided with a window controller, and automatic control of the window switch cannot be achieved. Therefore, the alarm 12 can send alarm information to the extractor hood, and the extractor hood opens the exhaust when the current gas concentration is within the safety range, so as to reduce the indoor gas concentration.

[0082] It can be understood that when the degree of gas leakage is slight, the current gas concentration is within the safety range, and the extractor hood can be used for exhaust. However, when the degree of gas leakage is serious, the opening of the extractor hood can produce an electric spark, which can cause the leaked gas to explode, and therefore the extractor hood cannot be used.

[0083] For example, the gas device 13 is a gas stove,

[0084] The gas device 13 is configured to close the gas stove valve according to the alarm information.

[0085] In specific implementations, the gas stove can send the state of the gas stove valve to the alarm 12, the alarm 12 uploads the state of the gas stove valve to the server 11, and the server 11 pushes the state of the gas stove valve to the user terminal 200, so that the user can remotely view the state of the gas stove valve through the user terminal 200, and can send a gas stove valve control instruction to control the gas stove valve according to the gas stove valve control instruction, so as to realize remote control of the gas stove valve. When the user forgets to close the gas stove valve when going out, the gas stove valve can be remotely controlled to be closed, which can effectively improve the intelligence and safety of gas use. After receiving the alarm information, the gas stove controls the gas stove valve to be closed, which can effectively avoid further gas leakage caused by the opening of the gas stove valve.

[0086] In the embodiments of the present application, each gas device can perform a gas leakage protection operation according to the alarm information, and through the cooperation of at least one gas device, the risk can be effectively eliminated, the gas leakage can be timely and reliably handled, and the safety of gas use can be effectively improved.

In addition, the coupling or direct coupling or communication connection between the units shown or discussed can be indirect coupling or communication connection through some interfaces, devices or units, which can be electrical, mechanical or other forms.
