Description

Technical Field

[0001] This utility model belongs to the field of power supply reading and writing technology, specifically relating to a power supply wireless communication reading and writing device. Background Technology

[0002] In the production and testing of electronic products such as servers and communication equipment, it is often necessary to configure parameters, read status, and debug the functions of the internal power modules. Currently, the industry generally uses wired communication methods. (See [link to relevant documentation]). Figure 1 For example, physical cables, such as those using I2C bus or UART interfaces, connect the test equipment to the management interface on the power supply module under test (DPDT) for data reading and writing. However, in certain testing scenarios, such as when the entire device is placed in a high or low temperature test chamber, an electromagnetic shielding room, or a compact integrated cabinet, the DPDT is located in a physically enclosed or inaccessible space. In these situations, connecting via physical cables becomes extremely difficult, not only due to cumbersome wiring and inconvenient operation, but also because cables may break the seal of the test chamber, affecting the accuracy of the test environment. Utility Model Content

[0011] Preferably, in the power supply wireless communication read / write device, the first wireless communication module is connected to the power supply device under test via an I2C interface.

[0012] The present invention, by adopting the above technical solution, has at least the following beneficial effects:

[0013] It is understood that the power supply wireless communication read / write device disclosed in this utility model includes: a first wireless communication module, whose data interaction port is electrically connected to the interface of the power supply device under test; a second wireless communication module, whose data interaction port is electrically connected to the interface of a test terminal; the first wireless communication module and the second wireless communication module are wirelessly connected, so that the test terminal can realize data interaction with the power supply device under test through the second wireless communication module and the first wireless communication module. It is understood that the technical solution disclosed in this utility model, through two wireless communication modules, can realize wireless communication between the power supply device under test and the test terminal, and has the advantages of simple operation, strong versatility, and plug-and-play functionality.

[0014] It should be understood that the above general description and the following detailed description are exemplary and explanatory only, and do not limit the present invention. Attached Figure Description

[0020] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0021] Figure 2 This is a schematic block diagram illustrating a power supply wireless communication read / write device according to an exemplary embodiment of this utility model. See also: Figure 2 A power supply wireless communication read / write device is provided, comprising:

[0022] The first wireless communication module 102 has its data interaction port electrically connected to the interface of the power supply device under test 101;

[0023] The second wireless communication module 103 has its data interaction port electrically connected to the interface of the test terminal 104;

[0024] The first wireless communication module 102 is wirelessly connected to the second wireless communication module 103, so that the test terminal 104 can interact with the power supply device under test 101 through the second wireless communication module 103 and the first wireless communication module 102.

[0025] In practice, during the R&D and production testing of electronic products, the power supply device under test (DPDT) 101 is often placed entirely within a sealed space with specific environmental conditions, while the test terminal 104, typically a computer or main control development board with dedicated testing software installed, is located outside the sealed space. In this situation, connecting the DPDT 101 and the test terminal 104 via physical cables is not only cumbersome but also requires the cables to pass through pre-drilled holes in the test chamber, potentially compromising the chamber's airtightness and thus affecting the accuracy of environmental testing.

[0026] The power supply wireless communication read / write device shown in this utility model can perform communication pairing after the first wireless communication module 102 and the second wireless communication module 103 are both connected to the corresponding devices. After pairing is completed, a two-way wireless data transmission channel is established between the two.

[0027] Specifically, the first wireless communication module 102 is used to directly convert the physical layer electrical signals (e.g., high / low level changes) received from the interface of the power supply device under test 101 into a specific format wireless communication signal and transmit it. Correspondingly, the second wireless communication module 103 is responsible for receiving the wireless communication signal, accurately restoring it to the same physical layer electrical signal as the original signal, and then outputting it to the test terminal 104. The reverse data transmission process follows the same principle, that is, the electrical signal emitted from the test terminal 104 is transmitted without distortion to the interface of the power supply device under test 101 via the second wireless communication module 103, the wireless data transmission channel, and the first wireless communication module 102. Throughout the transmission process, the two wireless communication modules only perform physical layer relay forwarding of the signal. Due to this transparent transmission mechanism that does not resolve protocols, this system can seamlessly support any existing test software and tools that use standard physical interfaces, thus achieving plug-and-play functionality.

[0028] It should be noted that in the aforementioned power wireless communication read / write device, both the first wireless communication module 102 and the second wireless communication module 103 are Bluetooth modules.

[0029] It should be noted that in the aforementioned power wireless communication read / write device, the second wireless communication module 103 is connected to the test terminal 104 via a USB interface.

[0030] It should be noted that in the aforementioned power wireless communication read / write device, the first wireless communication module 102 is connected to the power supply device 101 under test via an I2C interface.

[0031] In practical application, see Figure 3 The circuit schematic of the Bluetooth module is shown, in which the Bluetooth chip HC05 transmits and receives data through the TXD and RXD ports. Figure 4 The diagram shows the power supply circuit for the Bluetooth module, which provides power to the Bluetooth module.

Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model.
