[0041] In order to make the purpose, technical solution and advantages of the present invention clearer and more specific, the present invention is further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0042] In the prior art, the communication between the IoT platform and the IoT gas meter is intermittent, which will lead to inconsistent data between the IoT platform and the gas meter, and will inevitably lead to data errors. Therefore, a data synchronization method between the IoT platform and the gas meter is needed, which can establish a gas meter communication channel, receive and decrypt data, analyze anomalies to generate alarms, process settlement instructions and synchronize information display, so as to achieve real-time synchronization of data between the IoT platform and the gas meter.

[0043] The data synchronization method between the Internet of Things platform and the gas meter described in the preferred embodiment of the present invention is as follows: Figure 1 As shown, the data synchronization method between the Internet of Things platform and the gas meter includes the following steps:

[0044] Step S10: establishing a communication channel with the gas meter, and receiving encrypted data information of the current gas meter sent by the gas meter through the communication channel.

[0045] Specifically, a communication channel is established with the communication module on the gas meter based on the wireless communication protocol (a wireless remote communication module is pre-installed on the gas meter, such as an NB-Iot remote transmission module, and the gas meter forms an NB-Iot smart gas meter, and then the detection system establishes a communication channel with the communication module, so that the detection system can remotely receive the gas usage data of the gas meter through the communication channel). At present, the communication fee of the NB-Iot meter is already included in the factory, and no additional payment is required. Therefore, according to a user sending 3 messages per month (1 monthly fee, 1 balance information, 1 other message), 1 short message 0. Calculated at 1 yuan, a gas company with 1 million users can save 0.1*3*12*100=3.6 million yuan in SMS fees each year, wherein the communication module is pre-installed on the gas meter; the encrypted data information of the current gas meter is received and sent by the gas meter through the communication channel at preset reporting time. For example: in the process of the gas meter recording the gas usage data, a magnet device is provided on the mechanical wheel of the gas meter, and a corresponding Hall switch is installed under the mechanical wheel. When the mechanical wheel of the gas meter rotates one circle, the Hall switch will record once, so that the reading of the mechanical wheel of the gas meter can be converted into a digital signal.

[0046] Step S20: decrypt the data information of the current gas meter to obtain gas usage data, analyze the gas usage data, and generate an alarm prompt message if the analysis result is abnormal.

[0047] Specifically, a decryption instruction set sent by the Internet of Things is received, and the data information of the current gas meter is decrypted according to the decryption instruction set to obtain gas usage data; gas usage data in the gas usage data is obtained, and the gas usage data is analyzed; if there is a gas usage that is greater than a preset time and is less than or equal to a preset minimum threshold, an analysis result of a slight gas leak is generated (because when the gas is slightly leaking, the gas smell emitted is very faint, which is difficult for users to detect, and it is difficult for gas companies to check door to door, so in a preferred embodiment of the present application, the detection system will perform a corresponding slight gas leakage analysis on the gas usage data. By performing a slight gas leakage analysis on each gas usage data in the gas usage data, it can be concluded whether there is a slight gas leakage in the gas pipeline corresponding to the gas meter or in the user's home. If the gas is slightly leaked, the gas leakage analysis result can be obtained. If the analysis result of the gas data is a slight gas leak, an alarm will be generated and the next step of processing will be carried out according to the alarm); if the gas usage for more than the preset time is greater than or equal to the preset maximum threshold, an analysis result of a large gas leak will be generated (such as no gas use for a long time, no change in the reading for more than 15 days, a small flow rate for a long time, which is less than or equal to the current minimum range of the gas meter, and a large flow rate for a long time, which is greater than or equal to the current maximum range of the gas meter); if the analysis result is a slight gas leak and a large gas leak, prompt information will be obtained from the preset information prompt template library (different levels are represented by different lights, such as suspected gas leak: red; other warnings: yellow; general messages: green); corresponding alarm prompt information will be generated according to the prompt information, and the alarm prompt information is used to remind the user to close the gas valve and open the window for ventilation.

[0048] For example, the gas usage data contains 24 sets of gas usage data, each set of gas usage data represents the actual gas usage per hour. If the technician sets the preset number to 12 and the preset threshold to 0.025m 3 That is to say, when the specific values ​​of gas usage data of more than 12 groups in 24 groups of gas data are greater than 0 and less than or equal to 0.025m 3(That is to say, there are more than 12 hours in a day when gas is slightly used), then it can be determined that there is a slight gas leak in the gas pipeline corresponding to the gas meter, because ordinary users only use gas for a period of time every day, such as using a gas stove to cook or using a gas water heater to take a bath. During this period of time when gas is used, the actual gas usage will definitely be greater than the preset threshold, and in the remaining time when no gas is used, the actual gas usage should be 0. There will not be a situation where gas is used continuously for 24 hours and the actual gas usage is still very small. Therefore, it can be determined that there is a slight gas leak in the gas pipeline corresponding to the gas meter; it should be noted that the preset number is not set to 24 because it is necessary to exclude the normal use of gas by users. The specific value can also be set by technical personnel in the background of the detection system, and is not limited here.

[0049] Step S30, receiving the settlement instruction and gas meter related data sent by the Internet of Things platform, synchronously settling the gas usage data and the gas meter related data according to the settlement instruction, generating gas meter synchronization information, and sending the alarm prompt information and the gas meter synchronization information to the display screen of the gas meter for display.

[0050] Specifically, the gas meter related data includes the last cumulative usage, the last cumulative gas usage amount and the cumulative total gas purchase amount; the gas usage data includes the current cumulative usage and the current gas usage amount, and receives the settlement instruction and the last cumulative usage, the last cumulative gas usage amount and the cumulative total gas purchase amount sent by the Internet of Things platform; according to the settlement instruction, the difference between the current cumulative usage and the last cumulative usage is calculated to generate the current gas usage; according to the settlement instruction, the last cumulative gas usage amount, the cumulative total gas purchase amount and the current gas usage amount are calculated to obtain the current remaining amount (cumulative total gas usage amount = last cumulative gas usage amount + current gas usage amount, according to the cumulative total gas purchase amount and the cumulative total gas usage amount, calculate the current remaining amount: this remaining amount = cumulative total gas purchase amount - cumulative total gas usage amount Amount); Generate gas meter synchronization information according to the gas consumption this time and the remaining amount this time, and send the alarm prompt information and the gas meter synchronization information to the display screen of the gas meter for display (establish a network connection through NB-Iot, and send a message in Json format through the lwm2m protocol, such as {"Message":"The next security check date is December 31, 2024. Please make sure someone is at home by then."}, {"Message":"This meter reading is xxx, the last meter reading time is xxxxx, the last reading is xxx, the gas consumption this time is xxx, the amount is xxx yuan, and the current balance is xxx yuan."}, {"Message":"Dear user, there is a suspected gas leak in your gas meter. Please cut off the gas source immediately and open the doors and windows to keep ventilation."}).

[0051] Furthermore, according to the settlement instruction, the difference between the last cumulative gas usage amount and the current cumulative usage amount is calculated to generate the cumulative total gas usage amount; the remaining amount is calculated based on the cumulative total gas usage amount and the cumulative total gas purchase amount, and the preset color is matched according to the alarm prompt information to generate a red major reminder, a yellow minor reminder and a green safety reminder corresponding to the alarm prompt information; according to the red major reminder, the yellow minor reminder and the green safety reminder, the LED light is controlled to flash an alarm so that the user can read the information in time. Furthermore, after the gas meter receives the message from the system, it is displayed on the display screen, and the yellow LED is flashing according to the graded reminder to indicate that the gas meter has unread message reminders. To save power, the LCD screen of the gas meter is usually in the off state, and the screen display is lit by a short press of the read button of the gas meter. It will automatically go out 15 seconds after the user does not operate the read button. After the user presses the button to light up the screen to read all unread messages, the LED indicator light goes out.

[0052] Furthermore, if Figure 2 As shown, based on the data synchronization method between the Internet of Things platform and the gas meter, the present invention also provides a gas GIS-based pipeline inspection system, wherein the gas GIS-based pipeline inspection system includes:

[0053] The gas data information acquisition module 51 is used to establish a communication channel with the gas meter and receive the encrypted data information of the current gas meter sent by the gas meter through the communication channel;

[0056] Furthermore, if Figure 3 As shown, based on the data synchronization method and system between the above-mentioned Internet of Things platform and the gas meter, the present invention also provides a terminal accordingly, and the terminal includes a processor 10, a memory 20 and a display 30.
