Description

Technical Field

[0001] This invention belongs to the field of carrier communication module testing, and specifically relates to a multi-compatible HPLC carrier module testing device. Background Technology

[0002] In the power industry, terminal metering devices such as concentrators and electricity meters are equipped with carrier communication modules for communication and data transmission. Among these, HPLC carrier modules, characterized by large bandwidth and high transmission rates, meet the higher requirements of low-voltage power line carrier communication and are therefore increasingly widely used in power metering terminals. However, different power metering terminals have specific performance requirements and specifications for their carrier modules, and their testing equipment also varies. Field maintenance personnel often need to carry different types of testing equipment, increasing their workload. When testing equipment is inconvenient to carry, the module may even need to be disassembled and returned to the power supply station or sent to the metering center for testing. This prolongs the time cycle for module fault identification and reduces problem-solving efficiency. Furthermore, directly replacing the module with a new one presents new challenges in the disposal and classification of the disassembled module.

[0003] There are generally two approaches to detecting different types of HPLC carrier modules. One approach uses integrated detection equipment, such as a detection station capable of detecting multiple carrier modules. This station has workstations for various types of carrier modules, and the equipment is often integrated as a workbench. This type of equipment is mostly used for centralized detection of disassembled carrier modules. The other approach uses dedicated detectors. These detectors are often designed for a single type of carrier module, or even just a specific type from a particular manufacturer, making them easy to miniaturize and port. However, given the wide variety of carrier modules, these detectors struggle to handle situations with diverse field equipment. Summary of the Invention

[0004] The purpose of this invention is to provide a multi-compatible HPLC carrier module testing device to solve the problem that existing portable detectors, which are easy to miniaturize, cannot cope with the wide variety of field equipment.

[0005] To achieve the above objectives, the present invention provides a multi-compatible HPLC carrier module testing device, including a testing station, the testing station comprising a first, second, third, and fourth interface; the first interface is used to connect to the low-voltage interface of the concentrator carrier communication module; the second interface is used to connect to the low-voltage interface of the single-phase carrier communication module, and also to connect to the low-voltage interface of the three-phase carrier communication module; the third interface is used as the high-voltage interface of the single-phase carrier communication module; the fourth interface is used to connect to the high-voltage interface of the concentrator carrier communication module, and also to connect to the high-voltage interface of the three-phase carrier communication module. The relative positions of the first and fourth interfaces are consistent with the relative positions of the low-voltage and high-voltage interfaces on the concentrator carrier communication module; the relative positions of the second and third interfaces are consistent with the relative positions of the low-voltage and high-voltage interfaces on the single-phase carrier communication module; the relative positions of the second and fourth interfaces are consistent with the relative positions of the low-voltage and high-voltage interfaces on the three-phase carrier communication module.

[0006] Furthermore, it also includes a housing; the housing is a box structure, including a box handle and a box door; the surface of the box is provided with a groove for placing an identification device for identifying the identity of the HPLC carrier module under test, various interfaces of the test station, and an opening for installing an antenna for wireless communication testing of the HPLC carrier module; the box door is used to cover the groove and various interfaces when closed; the interior of the box contains test circuits and components for testing the HPLC carrier module.

[0007] Furthermore, the test components for testing the HPLC carrier module include a test board; the tests performed on the test board include power adaptability testing, chip ID testing, carrier module ID testing, carrier communication testing, carrier module program version testing, wireless communication testing, and supercapacitor charge / discharge testing of the HPLC carrier module.

[0008] Furthermore, there are two or more test stations, each of which includes the first, second, third and fourth interfaces, and each has a separate test channel for transmitting data when testing the HPLC carrier module connected to that test station.

[0009] Furthermore, each test station corresponds to a different set of test channels. The test channel corresponding to each test station is used to transmit data when testing the HPLC carrier module connected to that test station.

[0010] Furthermore, the test station includes a test station adapter board and a test station mounting board; the first, second, third and fourth interfaces are set on the test station adapter board; The test station adapter plate is installed on the back of the test station mounting plate. The test station mounting plate is provided with openings of different sizes that match the first, second, third and fourth interfaces on the test station adapter plate. The test station mounting plate is used to guide the interface of the HPLC carrier module to be tested, and connects to the corresponding interface of the carrier module on the test station adapter plate through the openings. The test station adapter board is connected to the test board via a ribbon cable. After the HPLC carrier module under test is connected to the corresponding interface on the test station adapter board, the test board transmits the test data of the HPLC carrier module.

[0011] Furthermore, the tests performed on the test board also include dual-mode wireless communication tests on the dual-mode HPLC carrier module.

[0012] Furthermore, the tests performed on the test board also include static power consumption tests and dynamic power consumption tests on the HPLC carrier module.

[0013] Furthermore, a human-machine interface is provided on the surface of the enclosure; the enclosure door is also used to cover the human-machine interface when closed.

[0014] Furthermore, the interior of the box also contains a label generating component for producing labels corresponding to the test results; the surface of the box is also provided with openings for installing the label generating component.

[0015] The above-described technical solution of this invention provides a multi-compatible HPLC carrier module testing device. Compared with existing HPLC carrier module testing devices, its advantages include: multiplexing connections between the low-voltage interfaces of the single-phase carrier communication module and the three-phase carrier communication module, and between the high-voltage interfaces of the concentrator carrier communication module and the three-phase carrier communication module, are achieved through the second and fourth interfaces of the testing station. This eliminates the need to reserve a separate connection position for each interface of each type of HPLC carrier module, ensuring that a single testing station can be compatible with the testing of these three types of HPLC carrier modules. Furthermore, the relative positions of these two interfaces are limited by the relative positions of the low-voltage and high-voltage interfaces on the three-phase carrier communication module. The relative positions of the first and fourth interfaces are limited by the relative positions of the weak and strong electrical interfaces on the concentrator carrier communication module, and the relative positions of the second and third interfaces are limited by the relative positions of the weak and strong electrical interfaces on the single-phase carrier communication module. Therefore, the distance between each pair of the first, second, third, and fourth interfaces is the same as or approximately the distance between the weak and strong electrical interfaces of a single HPLC carrier module. In other words, the area required for a single test station on the test device is approximately the same as the distance between the weak and strong electrical interfaces of a single HPLC carrier module. This improves the integration between the interfaces on the test station and effectively reduces the area occupied by a single test station on the test device. Therefore, it is convenient to realize the miniaturization and portability of multi-compatible HPLC carrier module test devices. Attached Figure Description

Detailed Implementation

[0017] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0018] Implementation of Multi-Compatible HPLC Carrier Module Testing Device This embodiment presents a technical solution for a multi-compatible HPLC carrier module testing device. By sharing an interface, it achieves a high degree of interface integration on the testing station. With fewer interfaces, it ensures that the testing station can be compatible with three different HPLC carrier modules. While ensuring the multi-compatibility of the testing device, it effectively reduces the space occupied by the testing station, making it easier to achieve miniaturization and portability of the multi-compatible HPLC carrier module testing device.

[0019] The multi-compatible HPLC carrier module testing device in this embodiment includes a testing station, wherein the testing station includes a first, second, third, and fourth interface; the first interface is used to connect to the low-voltage interface of the concentrator carrier communication module; the second interface is used to connect to the low-voltage interface of the single-phase carrier communication module, and is also used to connect to the low-voltage interface of the three-phase carrier communication module; the third interface is used as the high-voltage interface of the single-phase carrier communication module; the fourth interface is used to connect to the high-voltage interface of the concentrator carrier communication module, and is also used to connect to the high-voltage interface of the three-phase carrier communication module. The relative positions of the first and fourth interfaces are consistent with the relative positions of the low-voltage and high-voltage interfaces on the concentrator carrier communication module; the relative positions of the second and third interfaces are consistent with the relative positions of the low-voltage and high-voltage interfaces on the single-phase carrier communication module; the relative positions of the second and fourth interfaces are consistent with the relative positions of the low-voltage and high-voltage interfaces on the three-phase carrier communication module.

[0020] Therefore, the three sets of six types of interfaces—concentrator carrier communication module, single-phase carrier communication module, and three-phase carrier communication module—can be connected through the four interfaces of a single test station on the HPLC carrier module testing device. The second and fourth interfaces of the test station respectively realize the multiplexing connection of the low-voltage interface between the single-phase carrier communication module and the three-phase carrier communication module, and the high-voltage interface between the concentrator carrier communication module and the three-phase carrier communication module. This eliminates the need to reserve a separate connection position for each interface of each type of HPLC carrier module, ensuring that a single test station can be compatible with the testing of these three types of HPLC carrier modules. Furthermore, the relative positions of these two interfaces are determined by the relative positions of the low-voltage and high-voltage interfaces on the three-phase carrier communication module. Positional constraints; simultaneously, the relative positions of the first and fourth interfaces are constrained by the relative positions of the low-voltage and high-voltage interfaces on the concentrator carrier communication module, and the relative positions of the second and third interfaces are constrained by the relative positions of the low-voltage and high-voltage interfaces on the single-phase carrier communication module. Therefore, the distance between each pair of the first, second, third, and fourth interfaces is the same as or approximately the distance between the low-voltage and high-voltage interfaces of a single HPLC carrier module. In other words, the area required for a single test station on the test device is approximately the same as the distance between the low-voltage and high-voltage interfaces of a single HPLC carrier module, thereby improving the integration between interfaces on the test station and effectively reducing the area occupied by a single test station on the test device. Therefore, it is convenient to realize the miniaturization and portability of multi-compatible HPLC carrier module test devices.

[0021] In this embodiment, there are two or more test stations. Each test station includes the first, second, third, and fourth interfaces described above, and each has a dedicated test channel for transmitting data during the testing of the HPLC carrier module connected to that test station. This allows for simultaneous testing of different HPLC carrier modules at different stations, with each station able to test independently without interference. The number of active test stations does not affect testing efficiency. When there are many HPLC carrier modules to be tested, this improves the testing efficiency of the tested HPLC carrier modules and reduces the total time required to complete the testing of all carrier modules. The interfaces of each test station are distributed on the station panel.

[0022] In other embodiments, if testing efficiency is not considered and only size reduction is taken into account, only one testing station containing the first, second, third and fourth interfaces mentioned above can be set up. This setting can minimize the size of the testing device.

[0023] In addition, to ensure the relative independence of data channels when testing each type of HPLC carrier module, different test stations each correspond to a different set of test channels. Each test station's corresponding test channel is used to transmit data during the testing of the HPLC carrier module connected to that station; for example, test station 1, test station 2, and test station 3 have different channels, allowing each station to test independently. For the same station, different analytes share the same test channel to improve efficiency. Different test stations have their own independent set of channels; for each test station, when testing each type of HPLC carrier module, the shared interface uses the system's channel to transmit test data. That is, for each test station, the shared interface uses the same channel. Single-phase and three-phase carrier modules share a low-voltage interface, i.e., the second interface. Because the low-voltage interface definitions for single-phase and three-phase carrier modules are completely consistent according to the specifications, the same definition can be used for testing and data transmission. Similarly, the three-phase carrier module and the concentrator module share the same high-voltage interface, namely the fourth interface. According to the specifications, the high-voltage interface definitions of the three-phase and concentrator carrier modules are completely consistent, so the same definition can be used for testing and data transmission.

[0024] In one embodiment of this implementation, the testing device is provided with a total of 3 testing stations, namely: Figure 1The test station includes stations 1, 2, and 3; the first, second, third, and fourth interfaces of the test station are all plug-in connectors, facilitating compatibility with existing HPLC carrier module connectors. Specifically, the first, second, third, and fourth interfaces are four double-row female plug-in connectors, conforming to the State Grid specifications. In other embodiments, the first, second, third, and fourth interfaces can be adapted to other structures, as long as they match the interface of the HPLC carrier module and comply with relevant specifications. (Refer to...) Figure 1 A perspective view of the HPLC carrier module installation structure (each station has one type of HPLC carrier module installed). At station 1, the concentrator carrier module is installed on the upper side of station 1, and its connector is connected to the first interface 1 and the fourth interface 4 on the test station. As shown in station 2, the three-phase carrier module is installed on the lower left side of station 2, and its connector is connected to the second interface 2 and the fourth interface 4 on the test station. As shown in station 3, the single-phase carrier module is installed in the middle right side of station 3, and its connector is connected to the second interface 2 and the third interface 3 on the test station.

[0025] In this embodiment, the aforementioned multi-compatible HPLC carrier module testing device further includes a housing (i.e., a box shell); the housing is a box structure, including a box handle and a box door; the surface of the box is provided with a groove for placing a device for identifying the identity of the HPLC carrier module under test, various interfaces of the testing station, and an opening for installing an external antenna for wireless communication testing of the HPLC carrier module; the box door is used to cover the groove for placing the barcode scanner and the various interfaces of the testing station when closed; the interior of the box contains test circuits and components for testing the HPLC carrier module.

[0026] Therefore, by integrating the testing device into a portable case with a handle, it is convenient for testing personnel to carry the equipment to the field for module testing. Furthermore, the test circuits and components that do not need to come into contact with the outside are placed inside the case, while the identification device, test station, and antenna body or reserved position that need to interact with the outside are set on the surface of the case. The case cover covers the corresponding positions of the identification device and test station, ensuring the integration of the necessary functional components of the testing device, while preventing the identification device from falling out of the testing device or the interface on the test station from being affected by the external environment during the carrying process.

[0027] In addition, to facilitate testing operations, a human-machine interface is provided on the surface of the enclosure; the enclosure door is also used to cover the human-machine interface when closed. In one embodiment, the human-machine interface is a touch-screen all-in-one display (also referred to as a touch screen, display screen, or monitor); in other embodiments, other human-machine interfaces may be used, and no limitation is made here.

[0028] Furthermore, in this embodiment, the box also includes a label generating component for producing labels corresponding to the test results; the surface of the box also has openings for mounting the label generating component. Using the label generating component inside the box, labels corresponding to the test results can be directly produced after the test, facilitating rapid marking of faulty modules. In one embodiment, the label generating component is implemented using a printer; in other embodiments, other devices capable of generating labels can also be used.

[0029] In one embodiment, refer to Figure 2 and Figure 3 The aforementioned identification device is a wireless barcode scanner (which is more convenient to operate than a wired barcode scanner and does not require a hole to be reserved on the housing for the communication cable of the identification device). This corresponds to the case where the identity identifier of the HPLC carrier module being tested is a QR code or barcode. In other embodiments, other identification devices can also be used, as long as they match the identity identifier of the HPLC carrier module being tested.

[0030] Specifically, in this embodiment, the test component for testing the HPLC carrier module includes a test board; the tests performed on the test board include power adaptability testing, chip ID testing, carrier module ID testing, carrier communication testing, carrier module program version testing, wireless communication testing, and supercapacitor charge / discharge testing of the HPLC carrier module. In one embodiment, refer to... Figure 4 The test board includes a base plate and a core test module. The base plate provides basic power supply and a carrier interface, and mainly performs basic tests on whether communication and carrier functions are normal (i.e., power adaptability test and carrier communication test). The base plate also has an antenna interface, which can test whether the wireless module communication is normal (i.e., perform wireless communication test). The test module performs data processing and calculation, and performs chip ID test, carrier module ID test, carrier module program version test, and supercapacitor charge and discharge test functions, as well as data processing.

[0031] Figure 4 In this context, the carrier interface is the interface used for power line carrier communication with the carrier module under test, for example... Figure 1 The second and fourth interfaces are shown in the attached diagram; the power supply interface provides 220V voltage to the test board, please refer to the appendix. Figure 7 220V comes from the circuit breaker; the antenna interface is used to connect to the external antenna of the enclosure, mainly for testing the wireless communication function of the carrier module under test; XS1 is the network interface, refer to the appendix. Figure 7 The XS301 to XS305 are all adapter board ribbon interfaces used to connect to the test adapter board behind each workstation, so as to realize the connection between the test boards.

[0032] The test board in this embodiment also supports dual-mode testing, meaning that the tests performed by the test board also include dual-mode wireless communication testing of the dual-mode HPLC carrier module. The dual-mode wireless communication testing of the dual-mode HPLC carrier module is implemented through the test modules within the test board.

[0033] Furthermore, to further integrate the testing functions of the test board and meet more diverse testing needs, the tests performed on the test board also include static power consumption testing and dynamic power consumption testing of the HPLC carrier module. Both static and dynamic power consumption tests of the dual-mode HPLC carrier module are implemented through the test modules within the test board.

[0034] The detailed description of the functions implemented by the aforementioned test board is as follows: (1) Power supply adaptability test: The substrate provides three working voltages: 11V, 12V and 24V. The HPLC carrier module is tested to see if it is working properly.

[0035] (2) Chip ID detection: After recalling the chip ID, the chip ID is verified by MDS; the chip here refers to the chip of the module under test, which is mainly used for data storage and communication.

[0036] (3) Module ID detection: The HPLC carrier module ID is compared with the module silkscreen barcode.

[0037] (4) Program version test: Compare the version information of the HPLC carrier module with the filing information.

[0038] (5) Static power consumption test: Real-time monitoring of the 12V voltage and current of the HPLC carrier module to analyze static power consumption.

[0039] (6) Dynamic power consumption test: Real-time monitoring of the 12V voltage and current of the HPLC carrier module to analyze dynamic power consumption.

[0040] (7) Carrier communication test: The test results show that the internal attenuation of the main equipment is 20dB and the communication channel attenuation is 40dB. The test results show that the physical layer data frame transmission and reception are tested. This test item supports the testing of multiple interconnected HPLC carrier modules. During this process, multiple tests can be completed at the same time (pin level, 232 communication serial port, anti-attenuation, communication success rate, interchangeability, protocol consistency, long and short message tests can all be performed, all of which are existing test items).

[0041] (8) Dual-mode wireless communication test: Communicate with the HPLC carrier module through the dual-mode wireless channel (read module ID, complete network interaction, etc.) to test whether the dual-mode wireless communication function of the dual-mode HPLC carrier module is normal.

[0042] (9) Supercapacitor charge and discharge test: Power on the HPLC carrier module under test and charge the capacitor for 15 minutes (the specific charging time can be configured). After charging is completed, the module is powered off and then a power outage event is reported within 90 seconds.

[0043] In summary, in a specific embodiment, the testing procedure of the above-mentioned multi-compatible HPLC carrier module testing device is roughly as follows: 1) Connect the power supply to the equipment, open the cover, and insert the test sample (i.e., the HPLC carrier module to be tested) into the test station; the test device in this embodiment supports various versions of concentrators, single-phase and three-phase HPLC carrier communication modules of the State Grid, and supports dual-mode testing; 2) Take out the barcode scanner to scan the barcodes of the test items at the test station in sequence, click the start test button on the touch screen, select the corresponding test items, and test the test items through the test board; 3) Wait for the test to complete, click the corresponding button on the touch screen to print the label corresponding to the test result, and paste the label on the tested item.

[0044] Reference Figure 5 and Figure 6 In this embodiment, the testing station includes a testing station adapter plate and a testing station mounting plate; such as Figure 5 As shown, the first, second, third, and fourth interfaces of the test station are all located on the test station adapter board; The test station adapter plate is installed on the back of the test station mounting plate, such as... Figure 6 As shown, the test station mounting plate is provided with openings of different sizes that match the first, second, third, and fourth interfaces on the test station adapter plate, which are also the first, second, third, and fourth interface installation guides. The test station mounting plate is used to guide the interface of the HPLC carrier module under test to connect to the corresponding interface of the carrier module on the test station adapter plate through the above-mentioned openings (interface installation guides). The test station adapter board connects to the test board via a ribbon cable. After the HPLC carrier module under test is connected to the corresponding interface on the test station adapter board, the test board transmits the test data for that HPLC carrier module. Thus, the HPLC sample under test can be guided and installed on the test station adapter board through openings in the mounting plate.

[0045] like Figure 7As shown, test stations 1, 2, and 3 are connected to XS301, XS302, and XS303 respectively, which is a specific example of the test station adapter board being connected to the test board via ribbon cables. The power socket, circuit breaker, and power supply constitute the power circuit for the test board, monitor, industrial computer, and printer. The test board communicates with the industrial computer via a network cable, and is connected to the test station adapter board via a ribbon cable. The device under test (DUT) is mounted on the test station adapter board via the test station mounting plate. The wireless test module on the test board extends an antenna device to perform wireless communication testing of the DUT, thus forming a test communication circuit. Specifically, Figure 7 In the diagram, SPQ1 represents Adapter 1, which is the power adapter for the monitor; SPQ2 represents Adapter 2, which is the power adapter for the industrial computer; UR represents a combined power supply, used to convert voltage, such as converting 220V power to 24V; CS1 represents... Figure 4 The test board; PZCZ indicates a triangular socket; QF1 indicates a circuit breaker; XT indicates a terminal block.

[0046] Additionally, refer to Figure 8 The label generating component (e.g., a label printer) inside the box, which is used to produce labels corresponding to the test results, has its label output outlet, indicator lights, and power reset button located on the surface of one side of the box. The rest of the label generating component is mostly embedded inside the box.

[0047] In one specific embodiment, the test board, test station adapter board, industrial computer, printer, display, wireless barcode scanner, and test station mounting plate are all integrated into the housing (box) of the test device, wherein the display, test station, and barcode scanner are located on the front of the box, and the layout of the three is not limited to... Figure 3 As shown; the electrical interfaces (including power interface, network cable interface, and USB interface) of the embedded printer and testing device are located on the left side of the housing. The number and type of electrical interfaces are not limited to... Figure 8 As shown in the diagram; the antenna is mounted on top of the housing; the test board, industrial control computer, circuit breaker, combined power supply and other test circuit electrical components (i.e. test circuits and components used to test the HPLC carrier module) are installed inside the housing; the industrial control computer is mainly used to install the host computer software, and the circuit breaker is used to control the power on and off of the entire test device, and is the main switch of the test device.

[0048] It should be understood that the above-described specific embodiments of the present invention are merely illustrative or explanatory of the principles of the present invention, and do not constitute a limitation thereof.
