Description

Technical Field

[0001] This utility model relates to the technical field of communication module testing devices, specifically to a dual-mode communication module testing device for power line HPLC and HRF. Background Technology

[0002] HPLC technology is a high-speed power line communication technology that uses power lines as the communication medium for data transmission. Due to the high prevalence and wide coverage of power lines, it is extremely convenient and widely used in the field of power communication. HRF technology is an electromagnetic wave communication technology that is widely used in the communication field. It features long communication distance, strong anti-interference ability, high communication speed, and strong real-time performance. Combining HPLC and HRF technologies can achieve complementary advantages to meet the needs of smart grid construction. It has unique advantages in terms of in-depth application, minute-level data acquisition, service carrying capacity, and power outage reporting.

[0003] Existing power line HPLC and HRF dual-mode communication module testing devices generate HPLC and HPR signals respectively through HPLC and HRF signal transmitters, which are transmitted to the module under test (DUT) via a test base plate. Simultaneously, the device receives signals returned from the DUT to evaluate its performance. While this method enables the device to test dual-mode communication modules, it requires clamping and fixing the module during testing. During clamping, the position of the test interface is fixed and needs adjustment based on the testing location to ensure accurate testing of the RF interface performance. This results in poor flexibility during use. Utility Model Content

Four insertion posts 7 are arranged at the four corners of the bottom of the detection plate 6. The design of the electric slide rails 1 on the upright plate 5 facilitates the coarse adjustment of the position of the horizontal plate 2, so that the limiting plate 7 can be placed directly above the detection groove 21.

[0019] like Figures 1-6 As shown, in this embodiment, the upright plate 5 is screwed to the base box 3, the electric slide rail 1 is screwed to the upright plate 5, the horizontal plate 2 is screwed to the sliding block of the electric slide rail 1, and the hydraulic cylinder 4 is screwed to the horizontal plate 2.
