Description

Technical Field

[0001] The present application relates to the field of power technology, and more particularly to a method and system for testing an HDC dual-mode module product based on a balun circuit. Background Art

[0002] HPLC (High-speed Power Line Communications) high-speed power line carrier communication technology relies on line reliability for its operation. Additionally, the high impedance of the line can cause poor communication at its stations. HRF (High-speed RadioFrequency) high-speed wireless communication technology is affected by the environment, and reasons such as weather and building blockages can cause frame loss of channel data. To overcome the above problems, HDC (High-speed Dual-mode Communications), that is, HPLC+HRF dual-mode communication technology, has become an important promotion direction for the construction of new power systems.

[0003] To reduce the failure rate of the dual-mode communication unit, it needs to be comprehensively detected. Since the function of HRF is added to the function of HPLC, an additional link needs to be added to the product test plan. To improve production efficiency, it is increasingly valuable to test the two sets of functions in one workstation. However, due to limited fixture space, the HPLC carrier signal can easily cross the attenuator and couple through wires or space, making it difficult to accurately measure the anti-attenuation performance of the dual-mode module against communication signals.

[0023] Hereinafter, exemplary embodiments according to the present application will be described in detail with reference to the drawings. It should be understood that the specific embodiments described herein are only a part of the embodiments of the present application, and the present application is not limited by the exemplary embodiments described herein.

[0024] As Figure 1 shown, a method for testing an HDC dual-mode module product based on a balun circuit according to an embodiment of the present application includes step S1 and step S2.

[0025] In step S1, the barcode information of all HDC dual-mode modules to be tested is scanned and entered into the host computer system, and multiple HDC dual-mode modules to be tested are respectively docked with the corresponding modules in the detection tooling.

[0026] Scan the barcode information of all HDC dual-mode modules to be tested through a barcode scanner, and then input the scanned barcode information into the host computer system; the detection tooling includes a test box, a companion test box, an HPLC signal attenuator, and a radio frequency attenuator. There are multiple test bottom plates in the test box, and the test bottom plate includes a balun circuit A; there is a companion test bottom plate and a companion test module in the companion test box, and the companion test bottom plate includes a balun circuit B; the multiple HDC dual-mode modules to be tested are respectively communicatively connected to the multiple test bottom plates, the multiple test bottom plates are connected to the HPLC signal attenuator via coaxial signal lines, the HPLC signal attenuator is connected to the companion test bottom plate via a coaxial signal line, and the companion test module is communicatively connected to the companion test bottom plate; the balun circuit A of the test bottom plate is used to convert the HPLC differential signal of the HDC dual-mode module to be tested into a single-ended signal or convert the HPLC single-ended signal into a differential signal, and the balun circuit B of the companion test bottom plate is used to convert the HPLC single-ended signal of the HDC dual-mode module to be tested into a differential signal or convert the HPLC differential signal into a single-ended signal. After the HPLC signal is converted by the balun circuits of the test bottom plate and the companion test bottom plate, it is attenuated to different degrees by the HPLC signal attenuator, and the HPLC signal anti-attenuation performance of the HDC dual-mode module to be tested can be accurately measured; the test bottom plate is communicatively connected to the host computer, and the companion test bottom plate is communicatively connected to the host computer; the radio frequency attenuator is used for the attenuation of the HRF signal, and the HPLC signal attenuator and the radio frequency attenuator are adjustable attenuators, and the attenuation value can be adjusted according to the host computer instruction to accurately measure the anti-attenuation performance of the HDC dual-mode module.

[0027] In step S2, multiple HDC dual-mode modules to be tested enter the corresponding test modes according to the received test commands, and send the received test data to the host computer. The host computer obtains the detection results of each HDC dual-mode module to be tested according to the verification results of the test data; among them, the test modes include single-channel reception test, single-channel transmission test, dual-channel reception test, and dual-channel transmission test; the test data includes HPLC data and HRF data.

[0028] The host computer sends test commands to multiple test bottom plates through the network port. The test bottom plates receive the test commands and forward them to the corresponding HDC dual-mode modules to be tested. After the HDC dual-mode modules to be tested parse the commands, they enter the corresponding test modes. The test modes include single-channel reception test, single-channel transmission test, dual-channel reception test, and dual-channel transmission test; the host computer controls the closing or opening of the HPLC or HRF communication channels of the HDC dual-mode modules to be tested through the test commands, and performs the HPLC channel reception and transmission function test or the HRF channel reception and transmission function test once, or performs the HPLC+HRF dual-channel reception and transmission function test at the same time;

[0029] After the HDC dual-mode module to be tested enters the corresponding test mode, the host computer sends a control command to the accompanying test module, so that the accompanying test module sends test data to multiple HDC dual-mode modules to be tested according to the control command;

[0030] The host computer sends a control command to the accompanying test module through the accompanying test backplane.

The attenuated HPLC test data is transmitted to the HDC dual-mode module to be tested through the test backplane, and the attenuated HRF test data is transmitted to the HDC dual-mode module to be tested through the flat antenna; while the accompanying test module sends test data to multiple HDC dual-mode modules to be tested, it sends the test data to the host computer through the accompanying test backplane via the network port, so that the host computer uses this test data as the standard data to verify other received test data;

[0031] After receiving the test data, multiple HDC dual-mode modules to be tested determine the data forwarding method according to the current test mode, and send the test data to the host computer according to the data forwarding method. Specifically:

[0032] If the current test mode is single-channel reception test or dual-channel reception test, the HDC dual-mode module to be tested directly sends the test data to the host computer through the test backplane via the network port;

[0033] If the current test mode is single-channel transmission test or dual-channel transmission test, the HDC dual-mode module to be tested attenuates the test data through the HPLC signal attenuator or radio frequency attenuator and then sends it to the accompanying test module, so that the accompanying test module sends the test data to the host computer through the accompanying test backplane via the network port;

[0034] After receiving the test data from multiple HDC dual-mode modules to be tested, the host computer verifies the multiple test data with the above standard data, and obtains the detection results of each HDC dual-mode module to be tested based on the verification results.
