Description

Technical Field

[0001] This invention relates to the field of power monitoring technology, and in particular to a carrier meter reader with module detection function and its detection method. Background Technology

[0002] With the deepening of energy transition, the "new power system" will be the most important transformation in the future energy system. HPLC has already played a crucial role in the power grid's marketing and meter reading operations, and the transformation of the new power system business places higher demands on the in-depth application of HPLC. At the same time, it also places higher demands on the operation and maintenance of HPLC distribution stations to support the stable operation of these stations for in-depth applications.

[0003] A power line carrier communication (PLC) meter reader is an intelligent device used in power meter reading systems. It enables remote meter reading and control via PLC communication technology. However, in actual operation, even with HPLC systems aiming for 24 / 7 real-time meter reading, minute-level or intermittent data omissions still occur, resulting in incomplete data that is insufficient for in-depth testing and subsequent data acquisition and applications. Existing PLC readers primarily function as PLC network access devices and data readers, but they cannot detect PLC faults and require power lines to obtain PLC signals, leading to low security. Summary of the Invention

[0004] The purpose of this invention is to overcome the problems of existing carrier meter reading controllers, such as inability to perform fault detection, need for on-site power supply, limited applicability, and poor security. This invention provides a carrier meter reading controller with modular detection function and its detection method. It can realize multiple functions required for meter reading on-site through a single device, cope with various complex environments that occur during on-site carrier meter reading, eliminate the need for wiring and power supply, obtain carrier signals from power lines through a wireless carrier antenna, achieve convenient and fast carrier detection, realize multi-functional integration, strong versatility, and high security.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A carrier meter reader with module detection function includes: a handheld device, the front of which is provided with a functional module detection interface, the upper end of which is provided with a wireless carrier antenna and an infrared communication interface, the wireless carrier antenna being connected to a built-in carrier communication unit, the functional module detection interface sending frames of corresponding format and reading the corresponding responses from the carrier module, and the wireless carrier antenna analyzing the coupled carrier signals to distinguish uplink and downlink signals and determine whether the on-site electricity meter is connected to the network.

[0006] This device can handle various complex environments encountered during on-site carrier meter reading and control by providing multiple functions required by a single device. Operators only need one carrier meter reader to perform carrier module diagnosis, meter fault diagnosis, and carrier fault detection, without the need for wiring or power supply. It acquires carrier signals from the power line through a wireless carrier antenna, enabling convenient and rapid carrier detection. On-site personnel do not need to make contact with high-voltage wiring, making it safe and reliable to use. At the same time, the functional module detection interface can reduce the number of carrier modules on-site and accurately identify faults in carrier communication.

[0007] Preferably, the functional module detection interface includes a STA module channel interface and a STA module power supply interface, with single-phase STA modules and three-phase STA modules sharing one STA channel interface.

[0008] Preferably, the STA module power supply interface includes a three-phase STA module power supply interface, and a 4G module channel interface and a CCO module channel interface are vertically arranged between the three-phase STA module power supply interface and the STA module channel interface.

[0009] Preferably, the handheld device has a control module inside, which is connected to the touch screen and the function module detection interface to control all detection functions of the handheld device.

[0010] Preferably, the handheld device has a TF upgrade port at the bottom and a 220V power interface on the side.

[0011] Preferably, the touchscreen is equipped with LEDs of different rated voltages below it to display the battery voltage.

[0012] A detection method for a carrier meter reader with module detection function includes: S1: Acquire the carrier signal, analyze the coupled carrier signal, and determine whether the energy meter is faulty based on the uplink and downlink signals; S2: Obtain information about the accessed functional modules and determine the type of the accessed functional modules; S3: Send the corresponding detection format frame and determine whether the function module is normal based on the response information from the function module.

[0013] Preferably, step S1 includes: if only a concentrator downlink frame is detected but no meter uplink frame is detected, then it is a meter-side fault; if both uplink and downlink frames are detected simultaneously, and the uplink frame is correct, then it is a concentrator-side fault.

[0014] Preferably, if a response is received from the functional module, it indicates that the corresponding function is working properly; if no response is received from the functional module within the set number of attempts, it indicates that the compatibility test of the functional module has failed.

[0015] Preferably, the coupled carrier signal is a power line coupled to a non-contact carrier signal.

[0016] Therefore, the present invention has the following beneficial effects: 1. It can handle various complex environments that may occur during on-site carrier meter reading and control by providing multiple functions required by a single device. Operators only need one carrier meter reader to complete carrier module diagnosis, meter fault diagnosis, carrier fault detection, etc., achieving multi-functional integration and strong versatility.

[0017] 2. No wiring required for power supply: It obtains carrier signals from power lines through a wireless carrier antenna, enabling convenient and fast carrier detection. On-site testing personnel do not need to make contact with high-voltage wires, making it safe and reliable to use.

[0018] 3. By using the functional module detection interface to test the STA (site) module and CCO (central coordinator) module on site, the faults in carrier communication can be accurately identified. Attached Figure Description

Detailed Implementation

[0023] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments: Example 2: This embodiment provides a detection method for a carrier wave meter reader with module detection function. It acquires carrier signals from power lines via an antenna, enabling convenient and rapid carrier wave detection to determine whether the electricity meter and concentrator are faulty. Furthermore, on-site testing by personnel does not require contact with high-voltage power lines, ensuring safe and reliable operation. The method can identify the type of connected functional module and send corresponding detection format frames based on the module type. The response information from the functional module indicates its operational status, achieving multi-functional integration and strong versatility.

[0024] The following specific examples further illustrate the technical solution and effects of the present invention. The examples below are explanations of the present invention, but the present invention is not limited to the following examples.

[0025] like Figure 1 As shown, a detection method for a carrier meter reader with module detection function includes the following specific operation steps: Step 1: Obtain and couple carrier signals wirelessly, analyze the coupled carrier signals, and determine whether the energy meter is faulty based on the uplink and downlink signals.

[0026] The coupled carrier signal is the carrier signal obtained by coupling the power line to the non-contact carrier signal.

[0027] The uplink and downlink signals of a carrier signal are distinguished by different frequencies or encoding methods. By parsing the coupled carrier signal, removing interference signals, and then identifying and analyzing the parsed carrier signal, the uplink and downlink signals in the carrier signal can be distinguished.

[0028] On the one hand, based on the uplink and downlink signals, it is possible to determine whether the carrier signal is faulty, thus achieving carrier fault detection. On the other hand, the uplink and downlink frames can be used to determine the grid connection problem of the on-site electricity meter. Specifically: if only the concentrator downlink frame is detected and there is no meter uplink frame, then it is a fault on the meter side; if both uplink and downlink frames are detected simultaneously, and the uplink frame is correct, then it is a fault on the concentrator side.

[0029] Step 2: Obtain information about the accessed functional modules and determine the type of the accessed functional modules.

[0030] The function module is inserted into the corresponding function module detection interface on the carrier meter reader. The function module detection interface sends a signal to the control module inside the carrier meter reader. The control module identifies the type of the function module that is connected based on the signal.

[0031] Step 3: Send the corresponding detection format frame and determine whether the function module is working properly based on the response information from the function module.

[0032] Based on the type of the accessed functional module, send the corresponding detection format frame. If a correct response is received from the functional module, it indicates that the corresponding function is normal; otherwise, record the number of times sent as 1, and send the corresponding detection format frame again. If a correct response is still not received, record the number of times sent as 2. Repeat this process until the number of times sent reaches the set threshold, then record the functional module compatibility test as failed.

[0033] If a response is received from the functional module, the corresponding function is working properly; if no response is received from the functional module within the set number of attempts, the compatibility test of that functional module has failed.

[0034] Specifically, for example, when testing the STA module, a DL / T645-2007 protocol frame is sent. If no response is received from the STA module, and this happens repeatedly within the set sending threshold, it is determined that "the STA module DL / T645-2007 compatibility test has failed," and the test result is displayed visually.

[0035] When testing the 4G module, a wireless communication protocol frame is sent. If no response is received from the 4G module, and this happens repeatedly within the set sending threshold, it is determined that "the 4G module wireless communication protocol compatibility test has failed," and the test result is displayed visually.

[0036] Furthermore, since there are various wireless communication protocols, such as GPRS, CDMA, and NB-IoT, different types of wireless communication protocols can be sent sequentially when testing a 4G module to achieve the testing of the 4G module.

[0037] Depending on the actual needs and the different functional modules being detected, Modbus protocol frames, RS-485 protocol frames, DLT698 protocol frames, and PLC protocol frames can also be sent.

[0038] Example 2: This embodiment provides a carrier meter reader with module detection function, and its front view is shown below. Figure 2 As shown, the side view is as follows Figure 3 As shown, the device includes a handheld device, a function module detection interface, a wireless carrier antenna 1, an infrared communication interface, and a carrier communication unit. The carrier communication unit is installed inside the handheld device, the function module detection interface is installed on the front of the handheld device, the wireless carrier antenna is installed on the top of the handheld device, the infrared communication interface is installed on the top of the handheld device and located to the right of the wireless carrier antenna, and the carrier communication unit is installed inside the handheld device and connected to the wireless carrier antenna. The function module detection interface sends frames of the corresponding format and reads the corresponding responses from the function modules. The wireless carrier antenna analyzes the coupled carrier signals to distinguish uplink and downlink signals and determines whether the on-site power meter is connected to the network.

[0039] The carrier meter reading controller with module detection function provided in this embodiment can be used to solve the following problems: Low-voltage centralized meter reading systems adopt a modular design, and different modules may be used in different application scenarios. The types of modules in the field are also increasing, including single-phase modules, three-phase modules, broadband carriers, narrowband carriers, and remote communication modules such as 2G / 3G / 4G modules. In the current production environment, different modules have different test fixtures, resulting in low testing efficiency and high maintenance costs. During on-site debugging, different equipment needs to be carried to test different modules, which leads to low efficiency in analyzing and locating problems.

[0040] It can achieve the following functions: It can handle various complex environments encountered during on-site carrier meter reading and control through a single device, requiring only one carrier meter reader to perform carrier module diagnosis, meter fault diagnosis, and carrier fault detection. No wiring or power is needed; it acquires carrier signals from the power line via a wireless carrier antenna, enabling convenient and rapid carrier detection. On-site personnel do not need to contact high-voltage power lines, ensuring safe and reliable operation. Simultaneously, the functional module detection interface reduces the number of carrier modules required on-site, accurately identifying faults in carrier communication.

[0041] The following specific examples further illustrate the technical solution and effects of the present invention. The examples below are explanations of the present invention, but the present invention is not limited to the following examples.

[0042] The front of the handheld console features a function module detection interface at the top and a 3.5-inch capacitive touchscreen at the bottom, enabling fully localized operation.

[0043] Furthermore, several LEDs 11 are installed below the touch screen. The power level of the carrier controller is displayed by LEDs with different rated voltages. The battery voltage of the carrier controller decreases as the power level decreases. When it decreases to a certain level, the LED with the highest rated voltage turns off. As the battery voltage continues to decrease, the LEDs with the corresponding rated voltages turn off. The overall power level of the handheld device can be determined by the number of lit LEDs.

[0044] The handheld console has a fixed functional module detection interface located above the touchscreen on the front, which is used for things like... Figure 1 The structural layout shown allows for the detection of all commonly used electricity meter modules within a limited handheld device space.

[0045] Specifically: The functional module testing interface includes a channel interface and a power supply interface. The channel interface includes STA module channel interface 3, 4G channel interface 4, and CCO channel interface 5. The power supply interface includes three-phase STA module power supply interface 6, single-phase STA module power supply interface 8, and power supply interface 0. The STA module channel interface, three-phase STA power supply interface, and power supply interface 0 are not arranged horizontally, and they are all located on the same horizontal line. In the layout gap between the three-phase STA power supply interface and the STA module channel interface, the 4G module channel interface 4 and the CCO module channel interface 5 are arranged vertically. This eliminates the problem of protruding carrier module pins and ensures that the 4G module channel interface and the CCO module channel interface do not affect the insertion and removal testing of the three-phase STA, saving space. One interface serves multiple purposes. The layout of all common communication module interfaces in the field is completed in a single handheld device structure, thereby realizing the testing of various commonly used energy meter modules.

[0046] Furthermore, in this embodiment, the single-phase STA module and the three-phase STA module of the energy meter module share a single STA module channel interface, but use different power supply interfaces. For example, when testing a three-phase STA module, the three-phase STA module is connected to both the STA module channel interface and the three-phase STA power supply interface; when testing a single-phase STA module, the single-phase STA module is connected to both the STA module channel interface and the single-phase STA power supply interface. By sharing the channel, all STA modules can be tested using only three interfaces.

[0047] Furthermore, the carrier wave meter reader with module detection function provided in this embodiment is used as follows: After a functional module is inserted into the corresponding functional module detection interface, the handheld device's channel interface receives the insertion command and sends the format frame corresponding to that channel module. If the channel interface reads a response from the inserted functional module, the function corresponding to that module is considered normal. For example, if the DL / T645-2007 protocol frame sent when testing the STA module does not receive a response from the STA module, and if no response is received from the STA module within a set number of attempts, then it is determined that "the DL / T645-2007 protocol compatibility test for this functional module has failed."

[0048] A concentrator is a device that collects, processes, and stores data from various electricity meters, and can exchange data with the master station. The Central Coordinator (CCO) is the communication unit within the concentrator, acting as the master node in the communication network and responsible for network control, network maintenance, and management. The Station (STA) is the communication unit within the electricity meter, acting as a slave node in the communication network.

[0049] Each handheld device channel interface can send multiple protocol frames, enabling the detection of functional modules of the same type with different protocols. It is compatible with single-phase STA modules, three-phase STA modules, CCO modules, and remote communication modules from different manufacturers that conform to relevant standards. It supports protocol consistency testing, on-site remote and local communication fault location, and R&D testing, production testing, and on-site operation and maintenance testing.

[0050] An external wireless carrier antenna 1 and an infrared communication interface 2 are installed on the top side of the handheld device. The wireless carrier antenna is connected to the built-in carrier communication unit. Through the principle of radiation coupling of carrier signals in power cables, it is coupled to the power line in a non-contact manner, so that carrier operation and maintenance can be carried out without power, solving the problem of troublesome on-site power supply and making the debugging work safer and simpler.

[0051] Furthermore, the wireless carrier antenna distinguishes uplink and downlink signals by analyzing the coupled carrier signals, and determines the grid connection problem of the on-site energy meter by analyzing the uplink and downlink frames. For example, if only the downlink frame of the concentrator is detected, but the uplink frame of the energy meter is not detected, it can be determined that the fault is on the meter side; if both the uplink and downlink frames are detected at the same time, and the uplink frame is correct, it can be determined that the fault is on the concentrator side.

[0052] In this embodiment, the handheld device is also equipped with a TF card upgrade port at the bottom. The handheld device software can be upgraded remotely using a TF card through the TF card upgrade port.

[0053] Furthermore, a 220V power interface 9 is located on the right side of the handheld device. The handheld device can be powered on-site via a 220V power cord. This allows for power access and carrier signal acquisition for carrier detection should the wireless carrier antenna malfunction. The 220V power interface also functions as a charging port.

[0054] The carrier meter reader provided in this embodiment integrates wireless carrier and functional module detection functions, and integrates interfaces for all standard functional modules. It can replace traditional tooling in production to perform basic functional testing, improving production efficiency, reducing costs, and is easy to carry for on-site debugging. While acquiring power line carrier signal frames without requiring power, it can also directly detect carrier modules suspected of being faulty, enabling a single handheld device to complete all carrier schemes on-site, achieving multi-functional integration.

[0055] Example 3: This embodiment provides a carrier meter reader with module detection function, further optimizes the solution provided in the embodiment, and applies the method to a specific application scenario.

[0056] With the deepening of energy transition, the "new power system" will be the most important transformation in the future energy system. HPLC has already played a crucial role in the power grid's marketing and meter reading operations, and the transformation of the new power system business places higher demands on the in-depth application of HPLC. At the same time, it also places higher demands on the operation and maintenance of HPLC distribution stations to support the stable operation of these stations for in-depth applications.

[0057] However, in actual operation, achieving real-time, 24 / 7 meter reading at the HPLC system is still hampered by factors such as intermittent meter reading failures caused by power load fluctuations, differences in meter reading procedures between devices, variations in device stability, and suboptimal communication performance of the HPLC modules. This results in minute-level or intermittent missed meter readings, making the data incomplete and insufficient to support in-depth testing, as well as providing adequate data support for subsequent data acquisition and applications. Currently, suitable on-site fault diagnosis devices for the 2.0 acquisition system are not yet available.

[0058] Under the new power system operating conditions, the operation and maintenance of the HPLC station area mainly faces the following problems: 1) Maintain the HPLC station's communication network to ensure the stability and integrity of high-frequency data; 2) Diagnosis and maintenance of communication equipment faults; 3) Commissioning and maintenance of newly installed or replaced equipment; 4) Routine equipment operation inspections and anti-electricity theft inspections.

[0059] Based on the need to solve the above problems, it is necessary to research and develop instruments for detecting carrier faults, which have the functions of on-site interconnection and integrated meter reading, power line carrier data monitoring, communication module fault diagnosis, and convenient on-site debugging functions, such as network query function and frequency band switching function. They can also assist in carrying out anti-electricity theft inspections. These functions greatly reduce the workload of operation and maintenance personnel and improve work efficiency.

[0060] This embodiment provides a carrier meter reader with module detection function, which can easily and quickly detect carrier faults in the field. It includes: The handheld device has a touch screen 2 located on the lower front of the main body, enabling fully localized operation of the carrier meter reader.

[0061] The front of the handheld device has a fixed functional module detection interface above the touch screen; the top of the handheld device has an external wireless carrier antenna and an infrared communication interface; the bottom of the handheld device has a TF card upgrade slot and a Type-C port; the right side of the handheld device has a 220V power interface and a power switch.

[0062] Furthermore, the touchscreen is a 3.5-inch capacitive touchscreen, which controls all the handheld's detection functions. An LED light 11 is located at the bottom of the touchscreen to display the power level.

[0063] The touchscreen connects to the control module inside the handheld device. The control module connects to the function module detection interface. After the corresponding function module is inserted into the corresponding function module detection interface, the touchscreen is used to select the type of function module to be detected, and a signal is sent to the control module. The control module sends the corresponding format frame through the function module detection interface. If the corresponding response from the function module is received, the corresponding function is determined to be normal. The control module sends the detection result to the touchscreen for display and simultaneously sends it to the handheld device's internal memory for storage. The stored content includes the detection time, the detected function module, and the detection result.

[0064] In this embodiment, the control module is also connected to a wireless communication module. The wireless communication module can receive control commands sent by the mobile device terminal or the control center, detect the corresponding functional modules, realize remote control, and support the testing of PC testing software and mobile device software.

[0065] The infrared communication interface can be used by infrared handheld devices to send control commands to the control module.

[0066] The handheld device is also equipped with a light sensor, which detects ambient light signals and sends the results to the control module. The control module then controls the brightness of the touchscreen display based on the light signals.

[0067] Furthermore, the functional module detection interface area includes a single-phase STA module interface, a three-phase STA module interface, a CCO module channel interface, and a 4G module channel interface. The interface sockets are compatible with the corresponding functional modules, enabling simultaneous detection of STA modules, CCO modules, and 4G modules. This integrates on-site meter reading, STA module detection, CCO module detection, and communication module fault diagnosis functions.

[0068] The handheld device features an external wireless carrier antenna, enabling it to acquire carrier signals without requiring on-site power, thus improving security while monitoring power line carrier data.

[0069] Furthermore, the TF card upgrade port allows for remote software upgrades to the handheld console via TF card; the Type-C port can charge the handheld console's power supply; the 220V high-voltage power interface connects to a power cord for on-site power supply; the power switch controls the handheld console's startup; and the handheld console's power supply has a built-in 5000mAh battery.

[0070] After adopting the above technical solution, the advantages of the carrier meter reader provided in this embodiment are: The wireless handheld device can handle various complex environments that may arise during on-site carrier meter reading and control by providing multiple functions required by a single device. Operators only need one prototype to complete carrier module diagnosis, meter fault diagnosis, and carrier fault detection. No wiring or power supply is required. It obtains carrier signals from the power line through a wireless carrier antenna, enabling convenient and rapid carrier detection. At the same time, it can also directly detect the STA (site) module and CCO (central coordinator) module on-site through the module interface to accurately identify faults in carrier communication.
