Description

Technical Field

[0001] The embodiments of the utility model relate to the technical field of power communication, and in particular to a power communication test development board and electronic equipment. Background Art

[0002] Existing data acquisition terminals cannot use a unified communication interface circuit for various communication modules, meaning they cannot adapt to communication with multiple circuits. One communication interface circuit can only connect to a specific communication module. If there are multiple different communication modules, multiple communication interface circuits must be used to implement them. This approach is complex and wastes materials.

[0003] Secondly, different remote modules have various control forms. Generally, one remote module is equipped with one terminal, and the remote module and terminal hardware are developed independently. The remote module hardware functions are simple, while the terminal hardware functions are complex. The remote module needs to be debugged after the terminal is debugged, which greatly increases the development cycle. If multiple forms of remote modules are equipped with different terminals, the development cycle will be unimaginable.

[0004] Therefore, the existing communication interface technology has the problem that a communication interface circuit can only be connected to a specific communication module and the corresponding terminal also matches the corresponding communication module, resulting in a relatively complicated implementation method and a relatively wasteful use of materials.

[0025] The power communication test development board and electronic equipment provided by the embodiment of the utility model have multiple terminal interface units set in the power communication test development board. This test development board can connect to multiple terminals and can be adapted to multiple terminal types, thus eliminating the need to set up multiple test development boards. The power communication test development board proposed in this application can be based on the different interfaces required by the communication terminal, so that multiple terminal interface units can output through a single output interface unit, thereby improving the flexibility and functionality of the matching degree between the various input terminals and terminals in a test development board, thereby improving the practicality of the test development board.

[0026] Furthermore, because multiple terminal interface units can be electrically connected to a single output interface unit, only one test development board is required to accommodate multiple telecommunication modules. This reduces the number of terminal device components, thereby lowering manufacturing costs and increasing the integration of the terminal's circuit board. Furthermore, the reduced number of circuit components shortens the terminal device's development cycle and the complexity of the terminal's hardware, enabling faster development and reduced manufacturing costs.

[0036] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the embodiments of the present invention will be described in detail below with reference to the accompanying drawings. However, those skilled in the art will appreciate that many technical details are provided in the embodiments of the present invention to help readers better understand the present application. However, even without these technical details and various variations and modifications based on the following embodiments, the technical solutions claimed in the present application can still be implemented.

[0037] Figure 1 A schematic diagram of the structure of a power communication test development board provided in one embodiment of the present utility model; Figure 2 Another structural diagram of a power communication test development board provided by an embodiment of the present utility model; Figure 3 A circuit diagram of a power communication test development board provided in one embodiment of the utility model.

[0038] refer to Figure 1 An embodiment of the utility model provides a power communication test development board, including: a development board body (not shown) and a power management unit 130, an output interface unit 140 and a plurality of terminal interface units 110 arranged on the development board body; the plurality of terminal interface units 110 are used to provide corresponding first-type interfaces to connect different types of terminals; the output interface unit 140 is connected to the plurality of terminal interface units 110, and is used to provide a second-type interface to connect to an analysis device to test the terminal; the power management unit 130 is electrically connected to the output interface unit 140 and the plurality of terminal interface units 110, respectively, and is used to supply power to the output interface unit 140 and the terminal interface unit 110.

[0039] The power communication test development board provided in the embodiments of the present invention includes multiple terminal interface units 110. This means that the test development board can connect to multiple terminals and thus accommodate multiple terminal types, eliminating the need for multiple test development boards. In other words, the power communication test development board can utilize different interfaces based on the needs of the communication terminals, allowing multiple terminal interface units 110 to output through a single output interface unit 140. This can improve the flexibility and functionality of the matching between the various input terminals and terminals in a test development board, thereby enhancing the practicality of the test development board.

[0040] Furthermore, since multiple terminal interface units 110 can be electrically connected to a single output interface unit 140, only one test development board is required to accommodate multiple remote communication modules. This reduces the number of terminal device components, thereby lowering manufacturing costs while also increasing the integration of the terminal's circuit board. Furthermore, the reduced number of circuit components shortens the terminal device's development cycle and the complexity of the terminal's hardware, enabling faster development and utilization of the terminal device while reducing manufacturing costs.

[0041] In some embodiments, the development board body may refer to a printed circuit board (PCB), which is used to place the terminal interface unit 110, the output interface unit 140, and the power management unit 130, and connect various electronic components through circuits. The development board body mainly plays the role of conduction and transmission.

[0042] In some embodiments, the terminal refers to an electric power device responsible for collecting and storing user electricity usage information data and uploading the data to the master station, such as a conventional electric power meter and an RTU (Remote Terminal Unit) device.

[0043] In some embodiments, reference Figure 2 The terminal interface unit 110 is a communication module interface unit 102. The communication module interface unit 102 is connected to the power management unit 130 and the output interface unit 140, respectively, and is used to provide an interface for connecting to the communication module to be tested. The terminal includes the communication module to be tested. Information exchange between terminals, between terminals and the master station, and between master stations is achieved through the communication module.

[0044] In some embodiments, the communication module interface unit 102 includes at least two of: a USB interface, a UART-USB unit, an I2C-USB unit, a USIM interface unit, a 100M Ethernet interface, an SDIO interface, or an I2S-USB unit.

[0045] In some embodiments, reference Figure 2 , also includes: a switching control unit 120 and a control unit 150, the switching control unit 120 is connected to multiple communication module interface units 102 respectively, and the switching control unit 120 is used to control one of the communication module interface units 102 to be connected to the output interface unit 140; the control unit 150 is connected to the switching control unit 120, and is used to provide a control signal to the switching control unit 120.

[0046] In some embodiments, reference Figure 3 The switching control unit 120 includes a load switch, and the load switch is electrically connected to each communication module interface unit 102 respectively.

[0047] In some embodiments, the load switch includes four pins: an input voltage pin, an output voltage pin, an enable pin, and a ground pin. When the enable pin of the load switch receives an enable signal from the control unit 150, the FET is turned on, thereby causing current to flow from the input pin to the output pin, and electrical energy is transferred to the downstream circuit, thereby realizing an electrical connection between the communication module interface unit 102 and the downstream output interface unit 140.

[0048] In some embodiments, reference Figure 3 The circuit may include multiple load switches, each of which is electrically connected to each power interface unit 110. When a corresponding communication module interface unit 102 needs to be connected, the control unit 150 sends an enable signal to the corresponding load switch, thereby turning on the corresponding load switch and electrically connecting the communication module interface unit 102 to the output interface unit 140.

[0049] In some embodiments, a load switch may be included, the load switch having multiple input voltage pins or multiple output voltage pins, each output voltage pin (input voltage pin) being electrically connected to a corresponding communication module interface unit. Figure 2 Taking the two communication module interface units in FIG1 as an example, the load switch includes two input pins, A1 and B1, and one output pin, Z1. When the switching control unit 120 is in the first working state, the A1 pin of the load switch is electrically connected to the Z1 pin of the load switch; when the switching control unit 120 is in the second working state, the B1 pin of the load switch is electrically connected to the Z1 pin of the load switch.

[0050] The power communication test development board includes four communication module interface units, which are electrically connected to the A1, B1, C1 and D1 input terminals of the load switch respectively; the first enable port EN1 of the control unit is electrically connected to the first enable port EN1 of the load switch, and the second enable port EN2 of the control unit is electrically connected to the second enable port EN2 of the load switch.

[0051] In some embodiments, the four communication module interface units 102 are respectively a first interface unit, a second interface unit, a third interface unit, and a fourth interface unit. The first interface unit is connected to the A1 input of the switching control unit, the second interface unit is connected to the B1 input of the switching control unit, the third interface unit is connected to the C1 input of the switching control unit, and the fourth interface unit is connected to the D1 input of the switching control unit. The control unit can issue two enable signals EN1 and EN2. For example, when the first enable signal EN1 is high and the second enable signal EN2 is high, the A1 input of the load switch is connected to the Z1 output, that is, the first interface unit is connected to the output interface unit 140, and the output interface unit 140 outputs the communication mode corresponding to the first interface unit. For example, when the first enable signal EN1 is high and the second enable signal EN2 is low, the B1 input of the load switch is connected to the Z1 output, that is, the second interface unit is connected to the output interface unit 140, and the output interface unit 140 outputs the communication mode corresponding to the second interface unit. For another example, when the first enable signal EN1 is low and the second enable signal EN2 is high, the C1 input of the load switch is connected to the Z1 output, that is, the third interface unit is connected to the output interface unit 140, and the output interface unit 140 outputs the communication mode corresponding to the third interface unit. For another example, when the first enable signal EN1 is low and the second enable signal EN2 is low, the D1 input of the load switch is connected to the Z1 output, that is, the fourth interface unit is connected to the output interface unit 140, and the output interface unit 140 outputs the communication mode corresponding to the fourth interface unit.

[0052] In some embodiments, the switching control unit can also be a mechanical switch, such as a toggle switch, a knob switch, etc. The gear position of the mechanical switch can be changed by manual operation to achieve the selection and switching of the communication module interface unit. For example, when the switching control unit is switched to the first gear position, the selection signal output by the switching control unit is the first signal (i.e., the communication mode of the first interface unit is output). When the switching control unit is switched to the second gear position, the selection signal output by the switching control unit is the second signal (i.e., the communication mode of the second interface unit is output).

[0053] In some embodiments, the terminal interface unit 110 includes at least two of the following: a concentrator acquisition terminal interface, a China Southern Power Grid concentrator acquisition terminal interface, an energy controller dedicated transformer terminal interface, a dedicated transformer acquisition terminal interface, and a converged terminal interface. By integrating multiple terminal interfaces into the power communication test and development board, it can accommodate a variety of terminal types, eliminating the need for a dedicated development board and effectively improving R&D efficiency.

[0054] In some embodiments, the output interface unit 110 includes at least two of: a USB interface, a UART-USB unit, an I2C-USB unit, a USIM interface unit, a 100M Ethernet interface, an SDIO interface, or an I2S-USB unit.

[0055] In some embodiments, the system further includes a protection unit connected to the power management unit 130 .

[0056] In some embodiments, the protection unit is a power adapter connected to the power management unit to power the unit. Debugging the communication module and terminal requires an external 220V or three-phase power source, and the high-voltage terminals are exposed, posing a safety hazard. Using an adapter to power the power management unit eliminates the exposed high-voltage terminals, significantly reducing safety risks.

[0057] Figure 3 This is an example of a specific solution. The specific circuit structure and driving principle of the relevant chip components can be found in the relevant technology and will not be described in detail here. Figure 3 The power switch is part of the power management unit. The TE-TTU T-board socket, TE-C1 T-board socket, TE-C2 T-board socket, TE-ZC3 T-board socket, TE-NC1 T-board socket, TE-NC2 T-board socket, TE-SCU T-board socket, or TE-CU T-board socket is the communication module interface unit. The USB_HUB is the output interface unit.

[0058] The power communication test development board provided by the embodiment of the present invention has multiple terminal interface units 110 provided therein. This test development board can connect to multiple terminals and thus can be adapted to multiple terminal types, eliminating the need to provide multiple test development boards. The power communication test development board proposed in this application can be based on the different interfaces required by the communication terminals, so that multiple terminal interface units 110 can output via a single output interface unit 140, thereby improving the flexibility and functionality of the matching degree between the various input terminals and terminals in a test development board, thereby improving the practicality of the test development board.

[0059] Furthermore, since multiple terminal interface units 110 can be electrically connected to a single output interface unit 140, only one test development board is required to accommodate multiple remote communication modules. This reduces the number of terminal device components, thereby lowering manufacturing costs while also increasing the integration of the terminal's circuit board. Furthermore, the reduced number of circuit components shortens the terminal device's development cycle and the complexity of the terminal's hardware, enabling faster development and reduced manufacturing costs.

Each module can be embedded in or independent of a processor in a computer device in hardware form, or stored in a computer device memory in software form, allowing the processor to call and execute the corresponding operations of each module.

[0063] The technical features of the above embodiments can be combined arbitrarily.
