At the same time, it can trigger the repeater to output multiple working voltages of 5V / 9V / 15V, completing the linkage test of interface reversible plug compatibility and multi-level PD fast charging function, comprehensively covering the test scenarios of repeater interface and protocol function, and solving the problem of insufficient test coverage in the past.

The simulated load test module achieves high-precision continuously adjustable current output, ensuring the accuracy of load testing; at the same time, it realizes accurate acquisition of multi-dimensional electrical parameters, fully meeting the needs of refined electrical performance testing of repeaters under all operating conditions.

[0019] 5. Achieve fully automated closed-loop testing, improving testing efficiency and data reliability. With the control module at its core, the system enables automatic issuance of test commands, automatic execution of test actions, and real-time acquisition and processing of test data. The entire testing process requires no manual intervention, significantly improving testing efficiency.

[0030] The following is combined Figures 1 to 9 The present application will be further described in detail with reference to specific embodiments.

[0031] Combination Figure 1 , Figure 2 As shown, the control module 5 of this application includes an MCU control board and peripheral circuits connected to the MCU control board. The MCU control board of the control module 5 is connected to the analog telephone test module 1, the Type-C double-sided test module 2, the PD trigger module 3, and the analog load test module 4, respectively.

[0032] Furthermore, in combination Figures 1 to 3 As shown, the Type-C double-sided test module 2 of this application includes a first-sided test circuit, a second-sided test circuit, and a power supply test circuit.

[0033] The first test circuit has an input terminal connected to a first DC power supply, a control terminal connected to control module 5, and an output terminal connected to repeater 6. This first test circuit simulates the correct insertion condition of the Type-C interface of repeater 6 based on a first control signal output from control module 5. The second test circuit has an input terminal connected to the first DC power supply, a control terminal connected to control module 5, and an output terminal connected to repeater 6. This second test circuit simulates the reverse insertion condition of the Type-C interface of repeater 6 based on a second control signal output from control module 5. The power supply test circuit has an input terminal connected to the first DC power supply, a control terminal connected to control module 5, and an output terminal connected to repeater 6. This power supply test circuit powers on or off repeater 6 based on a third control signal output from control module 5.

[0034] Specifically, the power supply test circuit includes a current acquisition unit, an optocoupler isolation unit, and a first switching unit. The input terminal of the current acquisition unit is connected to a first DC power supply, its communication terminal is connected to the control module 5, and its output terminal is connected to both the input terminal of the optocoupler isolation unit and the input terminal of the first switching unit. The control terminal of the optocoupler isolation unit is connected to the control module 5, and its output terminal is connected to the control terminal of the first switching unit. The output terminal of the first switching unit is used to connect to a repeater 6.

[0035] As an example, see reference Figures 1 to 3 As shown, the first-side test circuit of the Type-C double-sided test module 2 of this application includes a first-side relay RL51, the second-side test circuit includes a second-side relay RL52, the current acquisition unit includes a current acquisition chip U53, the optocoupler isolation unit includes an optocoupler U50, and the first switching unit includes a field-effect transistor U51. The Type-C double-sided test module 2 of this application also includes a first connector PD_CONN, a second connector P51, a third connector TYPE_C_F, and a fourth connector P52.

[0036] In this embodiment, pin NO5 of the first relay RL51 is connected to pin A5 of the third connector TYPE_C_F, wherein the third connector TYPE_C_F is used to connect to the first DC power supply; in this application, the first DC power supply is a 45W power adapter. Pin -8 of the first relay RL51 is connected to the second connector P51 via pin 2. Figure 2Pin 1 of the P7 terminal of the MCU control board in control module 5. Pin 6 (Com6) of the first relay RL51 is connected to pin 2 of the first connector PD_CONN, which is used to connect to the PSU port of the repeater 6 under test. Pin 1+ of the first relay RL51 is used to connect to the second DC power supply +24V.

[0037] Pin NO5 of the second relay RL52 is connected to pin A5 of the third connector TYPE_C_F. Pin -8 of the second relay RL52 is connected to pin 3 of the second connector P51. Figure 2 Pin 8 of the P9 terminal on the MCU control board. Pin 6 (Com6) of the second relay RL52 is connected to pin 3 of the first connector PD_CONN. Pin 1 (1+) of the second relay RL52 is used to connect to the second DC power supply +24V.

[0038] Pins 5 (SCL) and 6 (SDA) of the current acquisition chip U53 are connected to pins 2 and 3 of the fourth connector P52, respectively; the fourth connector P52 is connected to terminal P20 of the MCU control board of control module 5. Pin 1 (IN+) of the current acquisition chip U53 is connected to pins A4 and B4 of the third connector TYPE_C_F. The connection between pins 1 (IN+) and 2 (IN-) of the current acquisition chip U53 is connected to pin 4 of optocoupler U50 and the source (S) of field-effect transistor U51, respectively. Pin 1 of optocoupler U50 is connected to the second DC power supply +24V through resistor R51. Pin 2 of optocoupler U50 is connected to pin 7 of terminal P9 of the MCU control board through pin 4 of the second connector P51. Pin 3 of optocoupler U50 is connected to the gate (G) of field-effect transistor U51. The drain (D) of field-effect transistor U51 is connected to pin 1 of the first connector PD_CONN.

[0039] The principle of the Type-C double-sided test module 2 in this application is as follows: When repeater 6 needs to be tested, simulating the correct insertion condition of the Type-C interface, the MCU control board of control module 5 sends a low-level control signal to pin 8-8 of the first relay RL51 through pin 1 of terminal P7. This energizes the coil of the first relay RL51, causing pins 5 (NO5) and 6 (Com6) to engage and conduct. At this time, pin A5 of the third connector TYPE_C_F (connecting to the 45W power adapter) is connected to the PSU port of repeater 6 through pins 5 (NO5) and 6 (Com6) of the first relay RL51, and then through pin 2 of the first connector PD_CONN, thus simulating the power path when the Type-C interface is correctly inserted. Similarly, when it is necessary to simulate the reverse insertion condition, the MCU control board sends a low-level control signal to pin 8-8 of the second relay RL52 through pin 8 of the P9 terminal, so that pin 5 NO5 and pin 6 Com6 of the second relay RL52 are engaged. Pin A5 of the third connector TYPE_C_F is connected to pin 3 of the first connector PD_CONN through the second relay RL52 to realize the reverse insertion simulation.

[0040] For the power supply and power-off control of repeater 6: The current acquisition chip U53 monitors the current flowing through pins A4 and B4 of the third connector TYPE_C_F in real time, and transmits the data to the MCU control board of the control module 5 via pins SCL (pin 5) and SDA (pin 6) through the fourth connector P52. When the MCU control board needs to supply power to repeater 6, it sends a control signal to pin 2 of optocoupler U50 through pin 7 of its P9 terminal. The internal LED of optocoupler U50 conducts, causing the phototransistor between pins 3 and 4 to conduct, which in turn drives the gate G of field-effect transistor U51 to a high level. Field-effect transistor U51 conducts, and the current monitored by the current acquisition chip U50 supplies power to repeater 6 through the source S and drain D of field-effect transistor U51 via pin 1 of the first connector PD_CONN. When power is off, the MCU control board stops sending control signals, optocoupler U50 is turned off, field-effect transistor U51 is turned off, and the power supply path is disconnected. The control module 5 controls the on / off state of the field-effect transistor U51 by controlling the conduction and cutoff of the optocoupler U50, thereby realizing the on / off control of the power supply to the repeater 6.

[0041] The Type-C double-sided test module 2 of this application can not only accurately simulate the forward and reverse insertion conditions of the Type-C interface, but also monitor the power supply current in real time, providing reliable hardware support for the interface performance test of the repeater 6.

[0042] Furthermore, in combination Figure 1 , Figure 2 and Figure 4 As shown, the PD trigger module 3 of this application includes a PD trigger circuit and a PD voltage setting circuit.

The voltage setting terminal of the PD trigger circuit is connected to the output terminal of the PD voltage setting circuit, and the control terminal of the PD voltage setting circuit is connected to the control module 5. The PD voltage setting circuit receives the voltage control signal output by the control module 5 and outputs the corresponding voltage setting signal according to the voltage control signal. The PD trigger circuit triggers repeater 6 to output the corresponding PD operating voltage according to the voltage setting signal.

[0044] Specifically, the PD voltage setting circuit includes a first signal relay RLY61, a second signal relay RLY62, a third signal relay RLY63, and a voltage configuration unit. The control terminal of the first signal relay is connected to the control module 5. The first terminal of the first signal relay is connected to both the voltage setting terminal of the PD trigger circuit and the common switch terminal of the voltage configuration unit.

[0075] The working principle of the simulated telephone test module 1 in this application is as follows: Control module 5 controls the activation and deactivation of each analog relay (such as the first analog relay K27, the second analog relay K25, and the third analog relay K26) by outputting high and low level signals.

During this process, the voltage acquisition modules (AC voltage acquisition module and DC voltage acquisition module) acquire the AC and DC voltages of the RJ11 interface in real time through connector J75 (21st connector) and transmit the acquired data to control module 5. Control module 5, combined with preset test logic, determines whether the voltage parameters of repeater 6 under different simulated operating conditions meet the standards, thus realizing intelligent testing of the telephone interface function of repeater 6. Simultaneously, through the connection with the host computer via connector RJ11-PC1 (25th connector), the test data can be uploaded to the host computer for further analysis, storage, and report generation, improving the level of intelligent test management.
