Description

Technical Field

[0001] This application relates to the field of Internet of Things (IoT) technology, and in particular to a low-power operation method and IoT system for a smart gas detector. Background Technology

[0002] Ultrasonic metering instruments include liquid flow meters and gas flow meters. Gas flow meters are used to measure gas flow rate, primarily for accurately measuring gas flow in closed pipelines. They are widely used in urban pipeline gas metering, industrial gas metering, energy management, and the metering of various non-corrosive gases. Based on different metering principles, gas flow meters mainly include ultrasonic gas flow meters, turbine gas flow meters, electromagnetic gas flow meters, and Roots gas flow meters. With the development of IoT technology, the integration of gas flow meters with IoT technology can form IoT-enabled smart gas flow meters. These meters use the gas flow meter as a base meter and, through sensor communication technologies such as NB-IoT, LoRa, and bus, exchange various metering data, gas flow meter and controller status information, alarm information, and control parameters with a management platform.

[0003] With the development of technology and the acceleration of urbanization, gas leak detectors are being used more and more widely. They can detect gas leaks in real time, issue timely alarms, and effectively prevent gas leak accidents. However, traditional gas leak detectors mostly rely on on-site manual inspection and operation, which not only requires a lot of manpower and time, but also needs to be kept online at all times, resulting in high power consumption.

[0004] Therefore, there is an urgent need for a method to reduce the power consumption of gas leak detectors. Summary of the Invention

[0016] If the control feedback information indicates successful control, the Bluetooth connection between the detector and the gas flow meter will be disconnected, and Bluetooth will be set as a Bluetooth broadcast receiver to receive request information from multiple gas flow meters.

[0017] If the control feedback information indicates a control failure, the Bluetooth connection between the detector and the gas flow meter will be disconnected, and a reconnection test will be performed.

[0018] As some optional embodiments of this application, the step of sending the first instruction information through network communication based on the real-time gas release flow information includes: when the real-time gas release flow corresponding to the real-time gas release flow information does not reach the warning condition, the first instruction information is a sleep instruction.

[0019] As some optional embodiments of this application, the warning conditions include a first warning condition or a second warning condition;

[0020] The first warning condition is that the real-time gas release flow rate is greater than 0 and less than a first preset threshold.

[0021] The second warning condition is that the real-time gas release flow rate is greater than the second preset threshold and the release time exceeds the preset time threshold;

[0022] Wherein, the first preset threshold is less than the second preset threshold.

[0023] As some optional embodiments of this application, after sending the second instruction information via network communication based on the detection feedback information, the method further includes:

[0024] When the detection feedback information is unsafe, the detection feedback information is sent to the smart gas management platform via network communication, so that the smart gas management platform can issue an alarm signal to the user.

[0025] Furthermore, embodiments of this application provide a low-power IoT system for smart gas detectors, comprising a smart gas user platform, a smart gas service platform, a smart gas management platform, a smart gas sensor network platform, and a smart gas object platform connected in sequence, wherein the smart gas object platform includes:

[0026] A gas flow meter is used to acquire real-time gas release flow information; based on the real-time gas release flow information, it sends a first instruction message via network communication; wherein, when the real-time gas release flow corresponding to the real-time gas release flow information reaches a warning condition, the first instruction message is an activation instruction, which is used to activate the detector to detect the gas concentration; it receives detection feedback information from the detector; based on the detection feedback information, it sends a second instruction message via network communication; wherein, when the detection feedback information indicates safety, the second instruction message is a sleep instruction, which is used to put the detector into a sleep state;

[0027] The detector is used to receive a first instruction message sent by the gas flow meter; and based on the activation instruction, to activate the gas concentration detection module to detect gas leakage in the target space, and generate detection feedback information based on the detection results; to send the detection feedback information to the gas flow meter, and to receive a second instruction message generated by the gas flow meter based on the detection feedback information; and to control the on / off state of the gas concentration detection module based on the second instruction message.

[0028] As some optional embodiments of this application, the smart gas management platform is used to receive detection feedback information sent by the gas flow meter; wherein, when the detection feedback information is unsafe, the smart gas management platform sends an alarm signal to the smart gas user platform through the smart gas service platform;

[0029] The smart gas user platform is used by users to send query requests to the smart gas service platform.

[0030] The intelligent gas management platform and the intelligent gas object platform communicate via a network through an intelligent gas sensor network platform.

[0031] Furthermore, embodiments of this application provide a gas flow meter based on smart gas, comprising:

[0032] The acquisition module is used to acquire real-time gas release flow information;

[0033] The first sending module is used to send a first instruction message through network communication based on the real-time gas release flow information; wherein, when the real-time gas release flow corresponding to the real-time gas release flow information reaches the warning condition, the first instruction message is an activation instruction, and the first instruction message is used to activate the detector to detect the gas concentration.

[0034] A receiving module is used to receive the detection feedback information from the detector;

[0035] The second sending module is used to send a second instruction message via network communication based on the detection feedback information; wherein, when the detection feedback information is safe, the second instruction message is a sleep instruction, and the second instruction message is used to cause the detector to enter a sleep state.

[0036] Compared with existing technologies, the low-power operation method of the smart gas detector provided in this application involves the gas flow meter sending an activation command to the detector or management platform when the real-time gas release flow rate corresponding to the real-time gas release flow rate information reaches the warning condition. This activates the gas detection function of the detector, enabling it to detect the gas concentration in the target space. After detection, the detector returns detection feedback information generated based on the detection results to the gas flow meter. The gas flow meter then determines whether the gas concentration in the target space is within a safe range based on the detection feedback information. If it is within a safe range, it sends a sleep command to the detector or management platform, causing the detector to enter a sleep state. It can be seen that the detector in this embodiment is in a sleep state when the gas flow meter does not detect gas release flow or when the gas release flow is within a safe range. Only when the gas release flow reaches the warning condition is the detector activated to detect the gas concentration in the target space, thereby effectively reducing the detector's operating power consumption and extending the battery replacement cycle.

[0049] Those skilled in the art will understand that Figure 1 The structure shown does not constitute a limitation on the computer device and may include more or fewer components than shown, or combine certain components, or have different component arrangements.

[0050] like Figure 1 As shown, the memory 1005, which serves as a storage medium, may include an operating system, a network communication module, a user interface module, and electronic programs, and may also include a data storage module.

[0051] exist Figure 1 In the computer device shown, the network interface 1004 is mainly used for data communication with the network server; the user interface 1003 is mainly used for data interaction with the user; the processor 1001 and the memory 1005 in the computer device of this embodiment can be set in the computer device. The computer device calls the low-power operation IoT system based on smart gas detector stored in the memory 1005 through the processor 1001 and executes the low-power operation method based on smart gas detector provided in this embodiment.

[0052] It should be noted that the aforementioned computer equipment can be an external, independently operating hardware device, or it can be a hardware device built into the Internet of Things system itself.

[0053] In existing technologies, gas leak detectors are typically used to detect gas leaks. These detectors can issue timely alarms when a gas leak occurs, alerting users to take safety measures. To ensure proper operation, the detector needs to continuously monitor the gas concentration in the surrounding environment. Therefore, gas leak detectors must remain online at all times. This results in high power consumption for gas leak detectors, making them prone to malfunction or failure to operate normally. Consequently, gas leaks may go undetected, potentially leading to safety accidents.

[0054] Therefore, to ensure home safety, this application reduces the detector's operating power consumption based on the following method:

[0055] Reference Figure 2 Based on the aforementioned hardware environment, this embodiment provides a low-power operation method for a smart gas detector, applied to a gas flow meter, including the following steps:

[0056] Step S10: Obtain real-time gas release flow information.

[0057] It should be noted that the gas flow meter described in this application can be used in industrial, canteen and other scenarios with large gas consumption; the gas flow meter can also be a gas meter for use in home and other scenarios.

[0058] It should be noted that the real-time gas release flow information refers to the information that the gas flow meter can detect as currently being released. This real-time gas release flow information may include data such as gas flow rate, gas pressure, and gas temperature. This data can be used to monitor the safety of the gas pipeline network. If a leak or other abnormality occurs in the gas pipeline network, the gas flow meter can promptly detect it and issue an alarm, helping the gas company to take timely measures to protect people's lives and property.

[0059] Step S20: Based on the real-time gas release flow information, send a first instruction message via network communication; wherein, when the real-time gas release flow corresponding to the real-time gas release flow information reaches the warning condition, the first instruction message is an activation instruction.

[0060] It should be noted that the first instruction information can be sent to the detector or to the management platform, which then sends the corresponding instruction to the detector. In some implementations, the detector's relevant parameters and instructions (such as the first preset threshold) can be modified and controlled on the management platform, thereby increasing operational convenience.

[0061] As can be seen, in the embodiments of this application, the detector does not need to be constantly online. It is connected to the gas flow meter via network communication. Only when the real-time gas release flow rate corresponding to the real-time gas release flow rate information reaches the warning condition will the gas flow meter send an activation command via network communication. After receiving the activation command, the detector will enter the activation state and activate the gas concentration detection module inside the detector to detect the gas concentration in the target space.

[0062] In some embodiments, when the real-time gas release flow rate corresponding to the real-time gas release flow rate information does not meet the warning conditions, the instruction sent by the gas flow meter to the detector is a sleep instruction. In other embodiments, the detector is initially in a sleep state, and therefore only becomes active upon receiving an activation instruction. In these embodiments, when the real-time gas release flow rate corresponding to the real-time gas release flow rate information does not meet the warning conditions, the gas flow meter does not need to resend the sleep instruction to the detector.

[0063] Generally speaking, if the amount of gas released exceeds the normal range, it will be considered a gas leak. The specific gas release standard varies depending on the region and the type of gas. However, in general, if the amount of gas released exceeds the normal range, it may cause safety hazards, and warnings and other measures will be taken.

[0064] However, in practical applications, gas leaks can be prolonged leaks exceeding the normal flow range, or they can be extremely small leaks caused by users not properly closing the valve after use. Therefore, the warning conditions described in this application include a first warning condition or a second warning condition; the first warning condition is that the real-time gas release flow is greater than 0 and less than a first preset threshold; the second warning condition is that the real-time gas release flow is greater than a second preset threshold and the release time exceeds a preset time threshold; wherein, the first preset threshold is less than the second preset threshold.

[0065] When the real-time gas release flow rate is greater than 0 and less than the first preset threshold, there may be a very small flow leakage caused by the valve not being closed tightly after use, as mentioned above. In this case, there may also be safety hazards. Therefore, it is also necessary to pay attention to and issue warnings.

[0066] When the real-time gas release flow rate is greater than the second preset threshold and the release time exceeds the preset time threshold, this may be a relatively common leakage situation, that is, a large amount of gas leakage caused by the user forgetting to close the valve after use, and the duration has exceeded the preset safe time, so early warning processing is urgently needed.

[0067] It should be noted that the network communication includes at least one of Wi-Fi communication and Bluetooth communication. In a further embodiment, to improve communication efficiency, Bluetooth communication is preferred in this application. When Bluetooth communication is used, before sending the first instruction information via network communication based on the real-time gas release flow information, the communication connection between the gas flow meter and the detector should also be tested, that is:

[0068] The detector is subjected to an initial Bluetooth communication test, and specific fields are sent via Bluetooth communication; wherein, the specific fields include an activation command field and a sleep command field;

[0069] Receive control feedback information from the detector;

[0070] When the detector controls the gas concentration detection module based on the received specific field and the control is successful, the control feedback information is "control successful". If the control feedback information is "control successful", the Bluetooth connection between the detector and the gas flow meter is disconnected, and Bluetooth is set as a Bluetooth broadcast receiver to receive request information from multiple gas flow meters.

[0071] When the detector controls the gas concentration detection module based on the received specific field, and the control fails, the control feedback information is "control failure". If the control feedback information is "control failure", the Bluetooth connection between the detector and the gas flow meter is disconnected and a reconnection test is performed.

[0072] It should be noted that since a single Bluetooth device can be used to connect different gas flow meters and different detectors, during the connection test steps described above, the gas flow meter will send a specific field to the detector upon initial connection. This allows the detector to identify the gas flow meter's ID through this specific field in subsequent applications, thereby improving detection efficiency.

[0073] After receiving the activation command from the gas flow meter, the detector will activate the gas concentration detection module, compare the gas concentration in the target space, generate detection feedback information based on the detection information, and return it to the gas flow meter so that the gas flow meter can determine whether an alarm needs to be triggered. That is:

[0074] Step S30: Receive the detection feedback information from the detector.

[0075] The detection feedback information includes whether it is safe or unsafe; when the gas concentration in the target space is lower than a preset concentration threshold, the detection feedback information is safe; when the gas concentration in the target space is greater than or equal to the preset concentration threshold, the detection feedback information is unsafe.

[0076] When the detection feedback information indicates safety, the detector does not need to continue detecting the gas concentration in the target space. Therefore, the gas flow meter sends a sleep command to the detector, causing the detector to enter a low-power sleep state. However, if the gas flow meter continues to detect the release of gas flow for a period of time, and a preset safety time has been reached, the gas flow meter will again send an activation command to the detector via Bluetooth communication, enabling the detector to re-detect the gas concentration in the target space and prevent safety accidents.

[0077] When the detection feedback information indicates an unsafe situation, the gas flow meter transmits the feedback information to the smart gas management platform via network communication. This allows the smart gas management platform to issue an alarm signal to the user, enabling the user to take timely action, such as cutting off the gas supply, evacuating personnel, opening doors and windows, and handling the alarm. In other words:

[0078] Step S40: Based on the detection feedback information, send a second instruction information via network communication; wherein, when the detection feedback information is safe, the second instruction information is a sleep instruction, which is used to put the detector into a sleep state; when the detection feedback information is unsafe, send the detection feedback information to the smart gas management platform via network communication so that the smart gas management platform can issue an alarm signal to the user.

[0079] As can be seen, the logic diagram of the low-power operation method for the smart gas detector provided in this application is as follows: Figure 3 As shown, the gas flow meter detects the real-time gas release flow information and determines whether the real-time gas release flow information meets the warning conditions. If the warning conditions are not met, a sleep command is sent to the detector to keep the detector in a sleep state, thereby reducing operating power consumption. If the warning conditions are met, an activation command is sent to the detector to activate the detector and detect the gas concentration in the target space. After the detection is completed, the detector returns detection feedback information. The gas flow meter determines whether the detection result corresponding to the detection feedback information is safe. If safe, a sleep command is sent to the detector to put the detector into a sleep state. If unsafe, an alarm signal is sent to the smart gas service platform so that the smart gas service platform can issue an alarm signal to the user, so that the user can take appropriate measures in time, such as cutting off the gas supply, evacuating personnel, opening doors and windows, and handling the alarm.

[0080] In a further embodiment, the warning conditions also include a third warning condition: the real-time gas release flow rate is between a first preset threshold and a second preset threshold, and the release time exceeds a preset time threshold. The first and second preset thresholds can be determined based on different gas appliances. For example, the first preset threshold can be the minimum flow rate of the gas appliance. When the real-time gas release flow rate is lower than the first preset threshold, it indicates a possible gas leak, requiring activation of the detector. When the real-time gas release flow rate is greater than the second preset threshold, the detector is activated to increase safety when using large gas volumes. When the real-time gas release flow rate is between the first and second preset thresholds and the release time exceeds the preset time threshold, the detector is activated to increase safety when using medium and small gas volumes.

[0081] As can be seen, the detector in this embodiment is in a dormant state when the gas flow meter does not detect the gas release flow or the gas release flow is within a safe range. The detector is only activated when the gas release flow reaches the warning condition to detect the gas concentration in the target space, thereby effectively reducing the detector's operating power consumption and effectively extending the detector's battery replacement cycle.

[0082] Furthermore, to address the aforementioned technical problems, this application also provides: a low-power IoT system based on smart gas detectors, comprising a smart gas user platform, a smart gas service platform, a smart gas management platform, a smart gas sensor network platform, and a smart gas object platform connected in sequence, wherein the smart gas object platform includes:

[0083] A gas flow meter is used to acquire real-time gas release flow information; based on the real-time gas release flow information, it sends a first instruction message via network communication; wherein, when the real-time gas release flow corresponding to the real-time gas release flow information reaches a warning condition, the first instruction message is an activation instruction, which is used to activate the detector to detect the gas concentration; it receives detection feedback information from the detector; based on the detection feedback information, it sends a second instruction message via network communication; wherein, when the detection feedback information indicates safety, the second instruction message is a sleep instruction, which is used to put the detector into a sleep state;

[0084] The detector is used to receive a first instruction message sent by the gas flow meter; and based on the activation instruction, to activate the gas concentration detection module to detect gas leakage in the target space, and generate detection feedback information based on the detection results; to send the detection feedback information to the gas flow meter, and to receive a second instruction message generated by the gas flow meter based on the detection feedback information; and to control the on / off state of the gas concentration detection module based on the second instruction message.

[0085] As some optional embodiments of this application, the smart gas management platform is used to receive detection feedback information sent by the gas flow meter; wherein, when the detection feedback information is unsafe, the smart gas management platform sends an alarm signal to the smart gas user platform through the smart gas service platform;

[0086] The smart gas user platform is used by users to send query requests to the smart gas service platform.

[0087] The intelligent gas management platform and the intelligent gas object platform communicate via a network through an intelligent gas sensor network platform.

[0088] like Figure 4 As shown, a gas flow meter based on smart gas includes:

[0089] The acquisition module is used to acquire real-time gas release flow information;

[0090] The first sending module is used to send a first instruction message through network communication based on the real-time gas release flow information; wherein, when the real-time gas release flow corresponding to the real-time gas release flow information reaches the warning condition, the first instruction message is an activation instruction, and the first instruction message is used to activate the detector to detect the gas concentration.

[0091] A receiving module is used to receive the detection feedback information from the detector;

[0092] The second sending module is used to send a second instruction message via network communication based on the detection feedback information; wherein, when the detection feedback information is safe, the second instruction message is a sleep instruction, and the second instruction message is used to cause the detector to enter a sleep state.

[0093] It should be noted that each module in the smart gas flow meter in this embodiment corresponds one-to-one with each step in the low-power operation method of the smart gas detector in the aforementioned embodiment. Therefore, the specific implementation of this embodiment can refer to the implementation of the aforementioned low-power operation method of the smart gas detector, and will not be repeated here.

[0094] In some embodiments, such as Figure 5 As shown in the embodiments of this application, the low-power IoT system based on smart gas detectors can be connected to an IoT system. The IoT system includes a smart gas user platform, a smart gas service platform, a smart gas management platform, a smart gas sensor network platform, and a smart gas object platform, which are sequentially connected in communication, thus forming a standard five-platform IoT structure.

The physical entities of the smart gas user platform include various user terminals, such as mobile phones, computers, and dedicated terminals. Through integration with user information system software, user terminal services are realized.

Therefore, through the synergistic effect of these functional modules, an interactive five-platform structure for the Internet of Things (IoT) is achieved, providing a framework for the low-power operation of the intelligent gas detectors.

[0100] As can be seen, this application, by establishing a complete Internet of Things (IoT) information operation system, ensures the orderly operation of preliminary detection of gas leak flow and further screening of gas concentration within the target space, thereby achieving intelligent management of gas leaks and improving the safety factor of gas use. Based on the aforementioned IoT information operation system, the detector remains in a dormant state when the gas flow meter does not detect gas release flow or when the gas release flow is within a safe range. The detector is only activated when the gas release flow reaches the warning condition to detect the gas concentration within the target space, thus effectively reducing the detector's operating power consumption and extending the battery replacement cycle.
