TECHNICAL FIELD

[0001] The present application relates to a gas meter registration method, in particular to a gas meter registration method in a gas IOT platform. BACKGROUND

[0002] The gas IOT (Internet of Things) platform uses technologies such as sensors, communication devices, and cloud computing to centralize data from multiple gas meters in a central system, thereby achieving real-time monitoring, remote management, and data analysis.

[0003] Registering a gas meter on a gas IOT platform usually requires the following steps: assigning a unique device number to each gas meter during its production process; writing this device number into the gas meter's storage device or internal memory; manually connecting the gas meter to a host computer through a suitable interface; and writing the gas meter's device number and module number into the gas IOT platform through the host computer and registering it. Since this process requires manual operation and can only register one gas meter at a time, it is inefficient and increases labor costs. SUMMARY

[0004] The purpose of the present application is to solve the problem of the existing gas meter registration method on the gas IOT platform, which requires manual operation throughout the process and can only register one gas meter at a time, resulting in low efficiency and increased labor costs. The present application provides a gas meter registration method on the gas IOT platform.

[0005] To solve the above-mentioned problems of the prior art, the present application provides the following technical solutions:

[0006] A gas meter registration method on a gas IOT platform, characterized in that a registration system is used, which includes a host computer, a base, and a collection module. The host computer is provided with a server. The base is provided with a detection and recognition area. The collection module includes a module housing above the base, and a control unit, a camera device, an infrared communication component, and a WiFi module inside the module housing. The control unit is provided with embedded software, which is provided with a camera device control program, an infrared communication control program, and a WiFi communication control program. The camera area of the camera device corresponds to the detection and recognition area.

[0007] The registration method includes the following steps:

[0008] Step 1: Place multiple gas meters to be registered in the detection and identification area of ​​the registration device, control the infrared communication component to send infrared signals to the multiple gas meters to be registered through the infrared communication control program to turn on the corresponding gas meters to be registered, and demodulate the return signals of the multiple gas meters to be registered to obtain the module number of the multiple gas meters to be registered.

[0009] Simultaneously, the camera device control program controls the camera device to acquire images. After obtaining images of multiple gas meters to be registered, image acquisition stops. Then, the camera device control program controls the camera device to execute image processing algorithms on the images of the multiple gas meters to be registered to obtain the device numbers of the multiple gas meters to be registered.

[0010] Step 2: Connect the WiFi module to the host computer's network via the WiFi communication control program. The WiFi module will then transmit the module number and device number of the multiple gas meters to be registered obtained in Step 1 to the server.

[0011] At the same time, the infrared communication control program controls the infrared communication component to send the device numbers of multiple gas meters to be registered to the corresponding gas meters to be registered;

[0012] Step 3: The server registers the module number and device number of multiple gas meters to be registered to the gas IoT platform via API call. Then, the server sends a termination command to the infrared communication component via the WiFi module, and the infrared communication component sends it to the gas meter to complete the registration.

[0013] Furthermore, in step 2, the step of transmitting the module number and device number of the multiple gas meters to be registered obtained in step 1 to the server by the WiFi module specifically involves controlling the WiFi communication control program to encapsulate the module number and device number of the multiple gas meters to be registered obtained in step 1 into a data packet, and then transmitting the data packet to the server by the WiFi module.

[0014] Furthermore, in step 3, the process of the server registering the module number and device number of multiple gas meters to be registered to the gas IoT platform via API calls specifically involves:

[0015] Step 3.1: Verify the integrity and security of the data packet from Step 2 through the server, and store the module number and device number of the multiple gas meters to be registered in the data packet into the database. Then, design all the module number and device number of the gas meters to be registered in the database as a database table.

[0016] Step 3.2: The server registers the database table from Step 3 to the gas IoT platform via API call, and determines whether the registration is successful based on the registration result returned by the gas IoT platform. If successful, proceed to the next step; otherwise, repeat Step 3.2.

[0017] Further, step 3.2 specifically includes:

[0018] Step 3.2.1: Send a request to the API endpoint of the gas IoT platform;

[0019] Step 3.2.2: Verify the API key of the API endpoint in Step 3.2.1;

[0020] Step 3.2.3: Construct the API request header and API request data, wherein the API request data is a database table;

[0021] Step 3.2.4: Initiate a POST request. Determine whether the request was successful based on the status code in the API response returned by the IoT platform. If it is, the API call is successful, and the gas IoT platform returns the registration result to the server. The server then determines whether the registration was successful based on the registration result. If it is, the server sends a termination command to the infrared communication component via the WiFi module, and the infrared communication component then sends it to the gas meter to complete the registration. Otherwise, return to step 3.2.1.

[0022] Furthermore, the camera device is one of a USB camera, a CSI camera, a MIPI camera, or a smart camera.

[0023] Furthermore, the infrared communication component employs one of the following: an infrared emitting diode and a receiving diode, an infrared sensor module, or an infrared array sensor.

[0024] Furthermore, the acquisition module also includes a USB interface disposed on the module housing and connected to the control unit, which is used to connect to the server through the host computer interface when the WiFi module cannot connect to the server.

[0025] Compared with the prior art, the beneficial effects of the present invention are:

[0026] (1) The present invention provides a method for registering gas meters on a gas IoT platform. The method employs a registration system, which obtains the device number and module number of multiple gas meters to be registered through a camera device and an infrared communication component, and automatically registers them to the gas IoT platform through a server. After registration is completed, the registered gas meters are deactivated. The present invention can automatically complete the registration of multiple gas meters on the gas IoT platform at the same time, which can greatly improve work efficiency and save labor costs.

[0027] (2) In the gas meter registration method of the present invention on the gas IoT platform, the infrared communication component can not only obtain the module number of multiple gas meters to be registered through infrared communication and transmit it to the host computer server, but also transmit the device number of multiple gas meters to be registered back to the corresponding gas meter to be registered (the device number of the gas meter to be registered is assigned to the surface / shell of the gas meter to be registered during the production process), and turn off the registered gas meter after successful registration to save energy.

[0036] The registration process includes the following steps:

[0037] Step 1: Place multiple gas meters to be registered in the detection and identification area of ​​the registration device.

[0041] Image processing algorithms are used to extract features of the device numbers of multiple gas meters to be registered from images of multiple gas meters to be registered. These features include edges, shape, and color.

[0042] The extracted features are used to identify the device numbers of multiple gas meters to be registered through pattern matching, thus obtaining the device numbers of multiple gas meters to be registered;

[0043] Step 2: The WiFi module is controlled by the WiFi communication control program to encapsulate the module number and device number of the multiple gas meters to be registered obtained in Step 1 into a data packet. The WiFi module is then connected to the host computer's network via the WiFi communication control program, and the WiFi module transmits the data packet to the server.

[0044] At the same time, the infrared communication component 5 is controlled by the infrared communication control program to send the device numbers of multiple gas meters to be registered to the corresponding gas meters to be registered;

[0045] Step 3.1: Verify the integrity and security of the data packet from Step 2 through the server, and store the module number and device number of the multiple gas meters to be registered in the data packet into the database of the server. Then, design all the module number and device number of the gas meters to be registered in the database as a database table.

[0046] Step 3.2: The server registers the database table from Step 3 to the gas IoT platform via API (Application Programming Interface).

[0047] Step 3.2.1: Send a request to the API endpoint of the gas IoT platform;

[0048] Step 3.2.2: Verify the API key of the API endpoint in Step 3.2.1;

[0049] Step 3.2.3: Construct the API request header and API request data, wherein the API request data is a database table;

[0050] Step 3.2.4: Initiate a POST request and determine whether it was successful based on the status code in the API response returned by the IoT platform. If it is, the API call is successful and the gas IoT platform returns the registration result to the server; otherwise, return to step 3.2.1.

[0051] Step 3.3: The server determines whether the registration was successful based on the registration result. If it was, proceed to step 3.4; otherwise, repeat step 3.2.

[0052] Step 3.4: The server sends a termination command to the infrared communication component 5 via the WiFi module, and then the infrared communication component 5 sends it to the gas meter to complete the registration.
