[0082] Step 1: Enter the meter number to start reading;

[0083] Step 2: Send a beacon frame through the reader to start networking;

[0084] Step 3: Determine whether the target node is connected to the network through the meter reading controller. If it is connected to the network, read the meter through the network access mode, organize the meter reading frame and send it. If it is not connected to the network, listen to the station area network ID, organize the meter reading frame in the non-network access mode and send it;

The module reading implementation process is shown in the figure below. The reading controller has the networking function. For the offline modules in the field area, the networking reading function can be realized. For the modules in the field area that have been connected to the network, the network ID can be listened to and the module reading can be performed using the network ID.

[0088] For details, please refer to the attached Figure 1-8 The signal diagnosis unit 90 performs simple noise collection and environmental noise diagnosis in the following specific steps:

[0089] Step 1: Perform ADC sampling on the power line signal. The HPLC communication technical specification defines four communication frequency bands, as shown in Table 3-1. The frequency band of the measured signal is 0.7MHz to 12MHz. According to the sampling theorem, the sampling frequency should be greater than 24MHz. This system uses a 25MHz sampling frequency to sample the noise signal. The HPLC communication technical specification stipulates that the subcarrier interval used in communication is 24.414KHz. In order to accurately evaluate the impact of noise on HPLC communication, the minimum number of sampling points is 1024 points. The number of single sampling points involved in this system is 2048, and the corresponding spectrum resolution is 12.207KHz.

[0090] Step 2: Obtain the frequency domain information of the interference signal through FFT operation. This system performs FFT operation through software operation. To ensure the operation performance, parameters such as the butterfly factor are obtained through table lookup.

[0091] Step 3: The frequency domain data processing unit processes and identifies the frequency domain data obtained by the FFT operation, and processes the frequency domain data by methods such as cyclic sampling, maximum hold, power spectrum accumulation, and peak detection, so that the processing result of the power line environmental noise information is more accurate;

[0092] It should be noted that in this embodiment, the signal diagnosis function is designed for locating environmental noise problems, and this function can be used to measure environmental noise and locate noise sources. The device displays the measurement results in a graphical form and indicates whether the environmental noise is too loud.

[0093] The signal diagnosis application collects the environmental noise of the power lines, analyzes the time-varying characteristics, amplitude-frequency characteristics, noise variation patterns, etc., and generates the noise intensity results of the on-site substation.

[0094] For details, please refer to the attached Figure 1-8 The carrier sensing unit 100 senses the carrier message and performs the following specific steps to troubleshoot the problem of isolated island or cross-station area:

[0095] Step 1: Select the frequency band and start listening;

[0096] Step 2: The message interception module completes the preliminary interception and analysis of the carrier message and stores the original message in the SD card;

[0097] Step 3: The message processing flow is divided into two parts: beacon processing and management message frame processing. The received central beacon frame, proxy beacon frame, and discovery beacon frame are processed through beacon processing. The list of nearby CCO addresses and nearby electric meters are obtained through beacon frame processing, which can be used to troubleshoot problems in isolated areas or cross-area areas. Management message frame processing mainly processes network access request frames and network access request response frames, and prompts are given when abnormalities are detected.

[0098] Step 4: Display the processing results, such as the CCO address list, neighboring meter list, abnormal information, etc. This information can be used to locate the island problem or cross-station problem in the substation area;

[0099] It should be noted that in this embodiment, the carrier sensing function is designed to locate the island problem and the cross-station problem in the substation area. The island problem or the cross-station problem can be located on site by listening to the carrier communication message at the meter end. This function analyzes the message and prompts the problem location result in the form of a list;

[0100] Furthermore, carrier sensing can select the frequency bands of 0.7-3M, 2-6M, and 2-12M according to the frequency band of the current station area. The station area association problem between the table and the concentrator is determined based on whether the message subtype contains association request, central beacon, or proxy beacon. Finally, the concentrator address to which the test table belongs will be displayed with the number of association requests.

[0101] For details, please refer to the attached Figure 1-8 The specific steps of the comprehensive diagnosis unit 120 performing comprehensive diagnosis and outputting a list of on-site problems are as follows:

[0102] Step 1: Enter the failure table address and start analysis;

[0103] Step 2: Comprehensively obtain the information from the module reading unit 80 to detect whether the module or collector is damaged, comprehensively obtain the information from the signal diagnosis unit 90 to determine whether there is noise interference on site, and output the result of whether there is noise interference through FFT operation, power spectrum data processing, and peak detection. Through the information obtained from the carrier sensing unit 100, locate the problem of isolated island or cross-station area in the substation area, and output the CCO address list, neighboring meter list, and abnormal information;

[0104] The comprehensive diagnosis unit 120 integrates and analyzes whether the detection module or collector is damaged, whether there is noise interference on site, and outputs a CCO address list, a neighboring meter list, and abnormal information, and finally outputs the result information of whether the module or meter is damaged, whether there is noise interference, whether it is an isolated island in the substation area, and whether it is a cross-station area;

[0105] It should be noted that in this embodiment, the comprehensive diagnosis function integrates the three functions of module reading, signal diagnosis, and carrier sensing, and reasonably designs the execution process. On-site users only need to connect the equipment and specify the target meter to start the comprehensive analysis and generate a problem list, which intuitively displays the results of the troubleshooting of module or collector damage, environmental noise, station island problems, and station cross-station problems. This function is specially designed for on-site problem troubleshooting, and only one application is needed to locate meter-side problems.
