Description

Technical Field

[0001] The present invention relates to the technical field of gas management, and in particular to an intelligent prompting system based on gas management. Background Art

[0002] Smart gas meter is a gas metering device with intelligent functions. It replaces the daily work of gas meter readers to a large extent and brings real-time and more comprehensive safety management for civil gas.

[0003] However, current gas meters are not connected to users' mobile devices such as mobile phones, and users cannot understand gas usage and the operating status of the gas meter in real time, which leads to insufficient gas recharge balance, low gas meter battery power, or gas being left on and forgotten to be turned off. Users are unable to detect it in time, which in turn creates safety hazards in gas use. Summary of the invention

[0004] In view of the above-mentioned shortcomings of the prior art, the present invention provides an intelligent prompt system based on gas management, which solves the technical problems raised in the above-mentioned background technology.

[0005] To achieve the above objectives, the present invention is implemented through the following technical solutions:

[0006] An intelligent prompting system based on gas management, comprising:

[0007] The control terminal is the main control end of the system and is used to issue execution commands; the interactive module is used to obtain the gas meter operation data and metering data in real time, and send the gas meter operation data and metering data to the user's mobile device; the sensor module is used to sense the real-time load of the cooker and measure the duration of the no-load state when the cooker is connected to the gas; the prompt module is used to set the prompt information trigger determination threshold, traverse the gas meter operation data and metering data obtained in the interactive module, and based on the comparison result of the gas meter operation data and metering data with the prompt information trigger determination threshold, feedback the prompt information to the interactive module; the maintenance module is used to control the opening or closing of the on-off valve installed on the gas pipeline; the message module is used to record the timestamp of the opening and closing of the on-off valve installed on the gas pipeline controlled by the maintenance module, and generate and store the message with the recorded timestamp of the opening and closing of the on-off valve;

[0008] Among them, the message format generated in the message module is manually set by the system end user;

[0009] The control terminal is interactively connected to an interactive module via a local area network, the interactive module is interactively connected to a backup unit and a monitoring unit at a lower level via a local area network, the interactive module is interactively connected to a sensor module via a local area network, the sensor module is electrically connected to an early warning unit via a medium, the early warning unit is interactively connected to the interactive module via a local area network, the sensor module is interactively connected to a prompt module via a local area network, the prompt module is electrically connected to a conversion unit via a medium, the prompt module is interactively connected to the backup unit and the monitoring unit via a local area network, the conversion unit is interactively connected to the monitoring unit via a local area network, and the prompt module is interactively connected to a maintenance module and a message module via a local area network.

[0010] Furthermore, the interaction module is provided with submodules at the lower level, including:

[0011] A backup unit, used to receive the gas meter operation data and metering data acquired by the interaction module, and to back up and store the gas meter operation data and metering data;

[0012] A monitoring unit, used for monitoring the reading status of the gas meter operation data and the metering data after the interaction module sends the gas meter operation data and the metering data to the user's mobile device;

[0013] Among them, the interactive module runs to synchronously obtain the running status of the backup unit. After the backup unit completes the backup storage of the gas meter running data and the metering data, it further executes the operation of sending the gas meter running data and the metering data to the user's mobile device. The gas meter running data includes: the remaining battery power of the gas meter, the gas recharge balance, and the opening and closing status of the gas supply channel. The gas metering data includes: daily gas usage, cumulative gas usage, and real-time average daily gas usage. When the backup unit backs up and stores the gas meter running data and the metering data, the gas meter running data and the metering data are differentiated and backed up and stored.

[0014] Furthermore, an operation cycle is set in the interaction module, the interaction module runs continuously based on the set operation cycle, the backup unit runs synchronously with the interaction module, and the remaining power of the gas meter battery in the gas meter operation data is represented by the real-time voltage of the gas meter battery:

[0015]

[0016] Where: Rd is the percentage of remaining battery power in the gas meter; V now is the current voltage of the gas meter battery; V lose The voltage of the gas meter battery when it is depleted; V start is the initial voltage of the gas meter battery;

[0017] Among them, the gas meter battery storage depletion state voltage Vlose Manually set by the system user. When the gas meter battery is a lithium battery, V lose The default setting is 3. When the gas meter battery is an alkaline battery, V lose The default setting is 1.

[0018] Furthermore, when the interactive module is running to send the gas meter operation data and metering data to the user's mobile device, the gas meter operation data and metering data are simultaneously compressed, and the user holding the mobile device receiving the data manually sets a decompression password. After the user receives the compressed gas meter operation data and metering data through the mobile device, the user enters the decompression password to decompress the compressed gas meter operation data and metering data, and reads the gas meter operation data and metering data. The monitoring unit monitors the reading status of the gas meter operation data and metering data, that is, monitors whether the compressed gas meter operation data and metering data are decompressed.

[0019] Furthermore, the sensor module is internally provided with submodules, including:

[0020] The early warning unit is used to receive the measurement result of the duration of the no-load state when the stove is connected to the gas in the sensor module, set the safety judgment threshold, compare the measurement result with the safety judgment threshold, and trigger the early warning information based on the comparison result;

[0021] Among them, when the metering result is within the safety judgment threshold, the early warning unit does not trigger the early warning information. When the metering result is not within the safety judgment threshold, the early warning unit triggers the early warning information. The early warning information triggered by the early warning unit is the specified audio data. The early warning information triggered by the early warning unit is sent to the user's mobile device through the interactive module and is not restricted by the operating cycle set in the interactive module. After the user's mobile device receives the early warning information, the built-in player app of the synchronous application mobile device opens the early warning information and plays it in a loop.

[0022] Furthermore, the safety judgment threshold set in the early warning unit obeys: the faster the gas usage measured by the gas meter changes and the longer the gas supply channel is open, the smaller the range of the safety judgment threshold, and vice versa.

[0023] Furthermore, there are two groups of prompt information trigger determination thresholds set in the prompt module, which are respectively applied to the gas recharge balance and the remaining battery power of the gas meter. When the prompt module traverses the gas meter operation data and metering data, the latest backup stored gas meter operation data and metering data are traversed in the backup unit. The prompt information fed back by the prompt module to the interactive module is the text information of "low battery power" and "low gas balance". The prompt information fed back by the prompt module to the interactive module is shelved in the interactive module, follows the operation cycle of the interactive module, and is compressed and packaged together with the gas meter operation data and metering data to be sent to the user's mobile device;

[0024] Among them, the prompt information compressed and packaged together with the gas meter operation data and the metering data is placed in the front position of the compressed and packaged data.

[0025] Furthermore, the prompt module is internally provided with submodules, including:

[0026] A conversion unit, used to obtain the read status of the gas meter operation data and the metering data monitored by the monitoring unit, and convert the prompt information format fed back by the prompt module to the interactive module based on the monitoring results;

[0027] Among them, the reading status of the gas meter operation data and metering data monitored in the monitoring unit obtained by the conversion unit is the latest three sets of compressed gas meter operation data and metering data reading status sent by the interactive module to the user's mobile device. When the reading status of the latest three sets of compressed gas meter operation data and metering data are all unread, and the earliest set of compressed gas meter operation data and metering data contains the prompt information feedback from the prompt module, the unread prompt information feedback from the prompt module is converted into audio format, and does not obey the operating cycle set in the interactive module. The built-in player app in the user's mobile device plays the prompt information in audio format in a loop.

[0028] Furthermore, the maintenance module operates to obtain the operating status of the early warning unit in real time. After the early warning unit triggers the early warning information, when the real-time load of the sensor module stove does not change, the on-off valve installed on the gas pipeline is controlled to close;

[0029] Among them, the control response time of the maintenance module is manually set by the system end user and shall not exceed 1 minute.

[0030] Compared with the known public technology, the technical solution provided by the present invention has the following beneficial effects:

[0031] The present invention provides an intelligent prompt system based on gas management. During operation, the system can collect and monitor the operation data and metering data of the gas meter in real time, and issue prompts when the gas meter is in a dangerous state of insufficient power, insufficient gas recharge balance, or when the gas stove is turned on for a long time, thereby ensuring the safety of daily use of gas and bringing more comprehensive safety services to gas users.

[0041] The interaction module 2 is provided with submodules at the lower level, including:

[0042] The backup unit 21 is used to receive the gas meter operation data and metering data acquired by the interaction module 2, and to back up and store the gas meter operation data and metering data;

[0043] A monitoring unit 22, used for monitoring the reading status of the gas meter operation data and the metering data after the interaction module 2 sends the gas meter operation data and the metering data to the user's mobile device;

[0044] The interactive module 2 synchronously acquires the operating status of the backup unit 21 when running.

[0048] Among them, when the metering result is within the safety determination threshold, the warning unit 31 does not trigger the warning information. When the metering result is not within the safety determination threshold, the warning unit 31 triggers the warning information. The warning information triggered by the warning unit 31 is the specified audio data. The warning information triggered by the warning unit 31 is sent to the user's mobile device through the interactive module 2 and is not restricted by the operating cycle set in the interactive module 2. After the user's mobile device receives the warning information, the built-in player app of the synchronous application mobile device opens the warning information and plays it in a loop;

[0049] Prompt module 4, used to set the prompt information trigger determination threshold, traverse the gas meter operation data and metering data obtained in the interactive module 2, and feedback the prompt information to the interactive module 2 based on the comparison result after comparing the gas meter operation data and metering data with the prompt information trigger determination threshold;

[0050] The prompt module 4 is internally provided with submodules, including:

[0051] The conversion unit 41 is used to obtain the read status of the gas meter operation data and the metering data monitored by the monitoring unit 22, and convert the prompt information format fed back by the prompt module 4 to the interactive module 2 based on the monitoring result;

[0052] Among them, the reading status of the gas meter operation data and metering data monitored in the monitoring unit 22 obtained by the conversion unit 41 is the latest three sets of compressed gas meter operation data and metering data reading status sent by the interactive module 2 to the user's mobile device. When the latest three sets of compressed gas meter operation data and metering data are read as unread, and the earliest set of compressed gas meter operation data and metering data contains the prompt information fed back by the prompt module 5, the unread prompt information fed back by the prompt module 5 is converted into an audio format, and does not obey the operation cycle set in the interactive module 2, and the built-in player app in the user's mobile device is used to loop the prompt information in audio format;

[0053] Maintenance module 5, used to control the opening or closing of the on-off valve installed on the gas pipeline;

[0054] The message module 6 is used to record the timestamps of opening and closing of the on-off valve installed on the gas pipeline controlled by the maintenance module 5, and to generate and store messages with the timestamps of opening and closing of the on-off valve recorded;

[0055] Among them, the message format generated in the message module 6 is manually set by the system end user;

[0056] The control terminal 1 is interactively connected to the interaction module 2 through the local area network, the interaction module 2 is interactively connected to the backup unit 21 and the monitoring unit 22 through the local area network, the interaction module 2 is interactively connected to the sensor module 3 through the local area network, the sensor module 3 is electrically connected to the early warning unit 31 through the medium, the early warning unit 31 is interactively connected to the interaction module 2 through the local area network, the sensor module 3 is interactively connected to the prompt module 4 through the local area network, the prompt module 4 is electrically connected to the conversion unit 41 through the medium, the prompt module 4 is interactively connected to the backup unit 21 and the monitoring unit 22 through the local area network, the conversion unit 41 is interactively connected to the monitoring unit 22 through the local area network, and the prompt module 4 is interactively connected to the maintenance module 5 and the message module 6 through the local area network.

[0057] In this embodiment, the control terminal 1 controls the interactive module 2 to operate and obtain the gas meter operation data and metering data in real time, and sends the gas meter operation data and metering data to the user's mobile device. The interactive module 2 obtains the gas meter operation data and metering data in real time, and sends the gas meter operation data and metering data to the user's mobile device. The monitoring unit 22 synchronously monitors the reading status of the gas meter operation data and metering data after the interactive module 2 sends the gas meter operation data and metering data to the user's mobile device. The sensor module 3 further senses the real-time load of the cooker and measures the duration of the no-load state when the cooker is connected to the gas. The early warning unit 31 synchronously receives the measurement result of the no-load state duration when the cooker is connected to the gas in the sensor module 3, sets a safety judgment threshold, and compares the measurement result with the safety judgment threshold. Yes, based on the comparison result, the warning information is triggered, and then the prompt module 4 sets the prompt information trigger determination threshold, traverses the gas meter operation data and metering data obtained in the interactive module 2, and compares the gas meter operation data and metering data with the prompt information trigger determination threshold after the comparison result, and feeds back the prompt information to the interactive module 2. The conversion unit 41 synchronously obtains the read status of the gas meter operation data and metering data monitored in the monitoring unit 22, and converts the prompt information format fed back to the interactive module 2 by the prompt module 4 based on the monitoring result. The maintenance module 5 operates in real time to control the opening or closing of the on-off valve installed on the gas pipeline, and finally records the timestamp of the opening and closing of the on-off valve installed on the gas pipeline controlled by the maintenance module 5 through the message module 6, and generates and stores the message with the recorded timestamp of the opening and closing of the on-off valve;

[0058] Through the operation of the system in the above embodiment, the use of gas is safely maintained and managed based on the gas meter operation data and metering data.

[0059] Embodiment 2:

[0060] In terms of specific implementation, based on Example 1, this example refers to Figure 1 The intelligent prompt system based on gas management in Example 1 is further described in detail:

[0061] An operation cycle is set in the interactive module 2. The interactive module 2 runs continuously based on the set operation cycle. The backup unit 21 runs synchronously with the interactive module 2. The remaining power of the gas meter battery in the gas meter operation data is represented by the real-time voltage of the gas meter battery:

[0062]

[0063] Where: Rd is the percentage of remaining battery power in the gas meter; V now is the current voltage of the gas meter battery; V lose The voltage of the gas meter battery when it is depleted; V startis the initial voltage of the gas meter battery;

[0064] Among them, the gas meter battery storage depletion state voltage V lose Manually set by the system user. When the gas meter battery is a lithium battery, V lose The default setting is 3. When the gas meter battery is an alkaline battery, V lose The default setting is 1.

[0065] Through the above logic, the remaining power of the gas meter is further limited and calculated.

[0066] like Figure 1 As shown, when the interactive module 2 runs to send the gas meter operation data and the metering data to the user's mobile device, the gas meter operation data and the metering data are compressed synchronously, and the user holding the mobile device receiving the data manually sets the decompression password. After the user receives the compressed gas meter operation data and the metering data through the mobile device, the user enters the decompression password to decompress the compressed gas meter operation data and the metering data, and reads the gas meter operation data and the metering data. The monitoring unit 22 monitors the reading status of the gas meter operation data and the metering data, that is, monitors whether the compressed gas meter operation data and the metering data are decompressed.

[0067] Through the above configuration, a designated monitoring logic is provided for the operation of monitoring the read status of the gas meter operation data and the metering data in the monitoring unit 22 .

[0068] like Figure 1 As shown, the safety judgment threshold set in the early warning unit 31 follows: the faster the gas usage measured by the gas meter changes and the longer the gas supply channel is open, the smaller the range of the safety judgment threshold, and vice versa.

[0069] Through the above settings, a further logical limitation is set for the safety determination threshold set in the early warning unit 31.

[0070] Embodiment 3:

[0071] In terms of specific implementation, based on Example 1, this example refers to Figure 1 The intelligent prompt system based on gas management in Example 1 is further described in detail:

[0072] There are two groups of prompt information triggering judgment thresholds set in the prompt module 4, which are respectively applied to the gas recharge balance and the remaining battery power of the gas meter. When the prompt module 4 traverses the gas meter operation data and metering data, the latest backup stored gas meter operation data and metering data are traversed in the backup unit 21. The prompt information fed back by the prompt module 4 to the interactive module 2 is the text information of "low battery power" and "low gas balance". The prompt information fed back by the prompt module 4 to the interactive module 2 is shelved in the interactive module 2, follows the operation cycle of the interactive module 2, and is compressed and packaged together with the gas meter operation data and metering data to be sent to the user's mobile device;

[0073] Among them, the prompt information compressed and packaged together with the gas meter operation data and the metering data is placed in the front position of the compressed and packaged data;

[0074] The maintenance module 5 obtains the operating status of the early warning unit 31 in real time. After the early warning unit 31 triggers the early warning information, if the sensor module 3 does not change the real-time load of the stove, the on-off valve installed on the gas pipeline is controlled to close;

[0075] The control response time of the maintenance module 5 is manually set by the system end user and is not greater than 1 minute.

[0076] Through the above settings, further operation logic limitations are made for the operation of the prompt module 4 and the maintenance module 5 in the system, ensuring that the system operates more stably and reliably.

[0077] In summary, in the above embodiments, the system collects and monitors the gas meter operation data and metering data in real time, and can issue prompts when the gas meter is in a dangerous state of insufficient power, insufficient gas recharge balance, or when the gas stove is turned on for a long time, thereby ensuring the safety of daily gas use and bringing more comprehensive safety services to gas users.

[0078] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that the technical solutions described in the aforementioned embodiments may still be modified, or some of the technical features may be replaced by equivalents. Such modifications or replacements will not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
