Description

Technical Field

[0001] This utility model relates to the field of interface testing, and in particular to an automated interface switching device. Background Technology

[0002] With the continuous upgrading of computer hardware and the constant changes in office scenarios, the types and brands of external devices are also constantly increasing. The requirements for the scalability and stability of external computer devices are also becoming increasingly stringent. Therefore, it is usually necessary to test the computer's system hardware compatibility to determine whether the computer's software and hardware compatibility is normal and whether the computer can adapt to different models of external devices and external expansion devices.

[0003] Due to the large workload of computer hardware testing and the large number of tests conducted daily, each computer needs to perform compatibility tests on different brands and types of external expansion devices, such as verifying the plug-in and unplugging functions of all different models of external devices and verifying their interchangeability. Manual testing involves a lot of repetitive work, which can easily lead to fatigue and slackness.

[0004] In addition, existing compatibility testing equipment is usually large in size and complex to operate, requiring a significant learning curve to master. Utility Model Content

[0005] In view of the problems existing in the prior art, this utility model proposes an automated interface switching device, which mainly solves the problem of the lack of equipment with simple structure and compatibility testing for different types of interfaces.

[0006] To achieve the above and other objectives, the technical solution adopted by this utility model is as follows.

[0007] This application provides an interface automatic switching device, the device comprising: a first side having a plurality of relatively independent first interfaces, wherein at least two of the first interfaces are of the same type; a second side having a plurality of relatively independent second interfaces, wherein at least two of the second interfaces are of the same type; and a switching module disposed between the first side and the second side to selectively connect the first interfaces and second interfaces of the same type in the first side and the second side.

[0008] Beneficial effects:

[0009] 1. Flexible input / output switching to adapt to simultaneous testing of multiple types of devices: This application sets multiple relatively independent interfaces on the first and second sides of the device, with at least two interfaces of the same type. Combined with the selective connection function of the switching module, it solves the problem of low compatibility verification efficiency caused by the single interface and inability to flexibly adapt to multiple external devices in traditional test equipment. Through the independent layout of the interfaces and the dynamic control of the switching module, free switching of input / output directions can be achieved, and simultaneous access testing of multiple types of peripherals can be supported, significantly improving the test coverage and efficiency.

[0010] 2. Meets the integrated requirements of plug-in / plug-out testing and interface switching testing: The device has two or more interfaces of the same type on one side, and the on / off control between interfaces is realized through a switching module. This solves the problems of repetitive labor, cumbersome operation, and low testing efficiency caused by the need for manual plugging and unplugging of peripherals in existing tests. This design can simulate the insertion and removal process of peripherals without physical plugging and unplugging. The plug-in / plug-out function verification and interface switching test are completed through automated switching, which greatly reduces labor costs and improves the consistency and accuracy of testing.

[0011] In summary, this solution systematically solves the core problems of low efficiency, complex operation, and bulky equipment in peripheral compatibility testing by optimizing interface redundancy configuration and dynamic switching, realizing the automation and efficiency of the testing process, and has significant technological progress and application value.

[0012] In one embodiment of this application, the device further includes a control side, which is provided with a control interface. One end of the control interface is connected to the switching module, and the other end is connected to the test terminal. A connection can be established with the test terminal through the control interface to receive test commands from the test terminal. The control interface can be configured to adapt to different test terminal types, meeting the connection requirements of different terminals.

[0013] In one embodiment of this application, the first interface includes: a USB interface, a Type-C interface, an HDMI interface, and an RJ45 interface. The interface type is not limited to these; it can be expanded to include the interface types of external devices to be tested, exhibiting strong scalability and compatibility with various conventional interface types to meet the differentiated testing needs of different vendors' equipment.

[0014] In one embodiment of this application, the second interface includes: a USB interface, a Type-C interface, an HDMI interface, and an RJ45 interface. Corresponding to the interface type of the first interface, it can also be expanded to accommodate the interface types of external devices to be tested, ensuring compatibility with various conventional interface types. Of course, customized interface expansion settings can also be implemented to meet the differentiated testing needs of different external devices.

[0015] In one embodiment of this application, the control interface includes a Type-C interface and a Wi-Fi interface. The control interface provides both Type-C and Wi-Fi connection methods. It can be directly connected to a computer via Type-C, allowing the computer to perform testing and control, controlling the switching module to open and close the interface and perform switching actions. Of course, wireless connection is also supported, enabling the connection between the test terminal and the device in scenarios where wiring is inconvenient, thus enhancing operability.

The first interface is connected one-to-one with the input of each 1-to-2 splitter, and the second interface is connected one-to-one with the output of each 2-to-1 multiplexer. The two outputs of each 1-to-2 splitter are respectively connected to the inputs of different 2-to-1 multiplexers corresponding to the same type of interface. Each 1-to-2 splitter connects to two first interfaces of the same type on the first side, and each 2-to-1 multiplexer connects to two interfaces of the same type on the second side. Four signal paths are formed through the 1-to-2 splitters and 2-to-1 multiplexers, enabling connection between any two interfaces of the same type on both sides. The opening and closing of the signal paths can be controlled by a test terminal, simultaneously meeting the testing requirements for interface plugging / unplugging and switching. The structure is simple and the operation is convenient. Beneficial effects: This application achieves miniaturization and ease of operation through modular design and unified chip control. By cross-connecting the one-to-two splitter unit and the two-to-one selector unit of the switching module, both units can use the same chip. Based on unified chip control of the data transmission path, it solves the problems of large size, complex structure, and high learning cost of traditional compatibility testing equipment. This design simplifies the hardware architecture and supports device miniaturization and plug-and-play functionality.

[0023] The following specific examples illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. This utility model can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of this utility model. It should be noted that, unless otherwise specified, the following embodiments and features can be combined with each other.

[0024] It should be noted that the illustrations provided in the following embodiments are only schematic representations of the basic concept of the present invention. Therefore, the drawings only show the components related to the present invention and are not drawn according to the number, shape and size of the components in actual implementation. In actual implementation, the form, quantity and proportion of each component can be arbitrarily changed, and the layout of the components may also be more complex.

[0025] The inventors discovered that in system hardware compatibility testing, a large number of machines are tested daily, and each computer needs to undergo compatibility tests with different brands and types of external expansion devices. This includes verifying the plug-and-play functionality and interchangeability of external devices with different signal strengths. Furthermore, current methods for system hardware compatibility testing, which involve repeatedly plugging and unplugging and swapping different peripherals, are prone to fatigue and complacency. For example, using the same USB flash drive to perform copy tests in different USB ports to check speed is necessary. Similar tests are also required using different brands of USB flash drives, and similar tests are needed for Type-C, HDMI, and other interfaces. The tests are repetitive and monotonous, easily leading to human error, and manual testing is costly.

[0026] In addition, most existing testing equipment is complex in structure and large in size, requiring a significant learning curve for newly trained testers, which can greatly affect testing progress and efficiency.

[0027] Based on the problems existing in the above-mentioned related technologies, this application provides an interface automatic switching device. The technical solution of this application will be described in detail below with reference to specific embodiments.

[0028] Please see Figure 1 , Figure 1 This is a schematic diagram of an interface automation switching device according to an embodiment of this application. The device includes: a first side 01, a second side 02, and a switching module 03. The first side 01 is provided with eight relatively independent first interfaces, each first interface being divided into four groups, and each group containing two first interfaces of the same type. Specifically, USB_1 and USB_2 form the first group, TYPE-C_1 and TYPE-C_2 form the second group, HDMI_1 and HDMI_2 form the third group, and RJ45_1 and RJ45_2 form the fourth group. The second side 02 is also provided with eight relatively independent second interfaces, each second interface being divided into four groups, each group containing two second interfaces of the same type. USB_1 and USB_2 form the first group, TYPE-C_1 and TYPE-C_2 form the second group, HDMI_1 and HDMI_2 form the third group, and RJ45_1 and RJ45_2 form the fourth group, so that the interfaces of the first side 01 and the second side 02 correspond to each other. A switching module 03 is positioned between the first side 01 and the second side 02. Each first interface and second interface is connected to the switching module 03. The switching module can selectively activate any two interfaces of the same type on the first side 01 and the second side 02. Since the interfaces on the first side 01 and the second side 02 are symmetrically arranged (i.e., the interface combination on the first side 01 is the same as the interface combination on the second side 02), the first side 01 can be selected as the input side and the second side 02 as the output side (e.g., ...). Figure 1 As shown), the second side 02 can also be selected as the input side and the first side as the output side 01. Figure 1 (Not shown in the image). Alternatively, one of the two identical first interfaces on the first side 01 can be selected as an input interface, and the other as an output interface. By utilizing the setting that there are at least two identical interfaces on the first side 01 and the second side 02, bidirectional input / output and interface switching function verification can be achieved. Taking the example that the first side 01 and the second side 02 respectively contain a USB_1 interface and a USB_2 interface, the USB_1 interface on the first side 01 can be selectively connected to the USB_1 interface or the USB_2 interface on the second side 02, or connected sequentially to the USB_1 interface and the USB_2 interface on the second side 02 to achieve interface switching test.

[0029] In one embodiment, the number of first interfaces and second interfaces corresponds. Of course, the specific types of first and second interfaces can be increased or decreased according to the requirements of the external device structure to be tested; this is not limited here. For example, each type of first or second interface is provided in pairs, enabling bidirectional input and switching through a paired structure on both sides.

[0030] In one embodiment, both interface switching and the testing process can be completed by the test terminal. The device of this application connects to the test terminal in use, providing the test terminal with various interfaces for connecting external devices, and can accept switch signals from the test terminal to switch between the data channels formed by the first interface and the second interface. The test terminal here can be a computer, such as a laptop or desktop computer. The device of this application establishes a connection with the test terminal via a TYPE-C interface or a WIFI interface to facilitate subsequent interface plug-in / plug-out tests, switching tests, etc.

[0031] like Figure 1 As shown, the switching module 03 includes four 1-to-2 splitters and four 2-to-1 multiplexers. Each 1-to-2 splitter includes one input and two outputs, and each 2-to-1 multiplexer includes one output and two inputs. A first interface is connected to the input of each 1-to-2 splitter, and a second interface is connected to the output of each 2-to-1 multiplexer. The two outputs of each 1-to-2 splitter are connected to the inputs of different 2-to-1 multiplexers corresponding to the same type of interface. Specifically, each first interface connects to one 1-to-2 splitter, which splits the data input from the external device into two paths for transmission. These two data paths enter two 2-to-1 multiplexers, and each 2-to-1 multiplexer connects to one second interface. Two 1-to-2 splitters corresponding to the same type of first interfaces and two 2-to-1 multiplexers corresponding to the same type of second interfaces are cross-connected. For an example, please refer to [link to example]. Figure 2 Taking a first side 01 and a second side 02 each containing two HDMI ports as an example, the two HDMI ports on the first side 01 are connected to the inputs of two 1-to-2 splitter units, and the two HDMI ports on the second side 02 are connected to the outputs of two 2-to-1 selector units. Each 1-to-2 splitter unit's two outputs are connected to one input of a different 2-to-1 selector unit, thus forming a cross-connection. The opening and closing of the formed cross-connection path can be controlled by the test terminal to selectively connect the corresponding data channel and perform the corresponding test. The specific number of 1-to-2 splitter units and 2-to-1 selector units included in the switching module 03 can be determined according to the interface type to be tested or the actual test efficiency requirements; no limit is imposed here.

[0032] In one embodiment, the 1-to-2 splitter unit and the 2-to-1 multiplexer unit can be implemented using the same chip. One input of the 1-to-2 splitter unit can be used as an output, while the corresponding two outputs can be used as inputs. In this case, the 1-to-2 splitter unit becomes a 2-to-1 multiplexer unit, which can meet the requirements of bidirectional input and switching. For example, the 1-to-2 splitter unit and the 2-to-1 multiplexer unit can be implemented using the ASW3642 chip. Of course, other chips can also be selected according to actual needs, and there is no limitation here.

[0033] In one embodiment, such as Figure 1As shown, both the first side 01 and the second side 02 are equipped with DC interfaces, which can be connected to an external power source to provide low-voltage DC power to the device, ensuring the normal operation of the switching module 03. Alternatively, a DC power supply unit can be installed within the device to achieve self-powering, meeting the need for immediate use and ensuring normal operation even without an external power source. The switching module 03 can supply power to the 1-to-2 splitter and the 2-to-1 selector units via the DC power supply unit. The DC power supply unit can be integrated into the device or an external power source can be used. If an external power source is used, the first or second interface can include a DC interface. The DC power supply unit can supply 5V, but it can also be adapted according to actual application requirements; no restrictions are imposed here.

[0034] In one embodiment, the device may also include a switch to connect or disconnect the DC power supply unit. The switch can be an inductive switch, a DIP switch, etc., and can be configured and adjusted according to actual application requirements. Alternatively, after connecting to a test terminal, the test terminal can control the on / off state of the corresponding switch.

[0035] In one embodiment, the device may further include a housing, which may be made of aluminum alloy to enhance reliability. The switching unit is placed inside the housing for sealing and isolation, preventing moisture, dust, etc., from contacting the switching unit. The interfaces on the first side 01 and the second side 02 may also be located on the housing, with the interfaces exposed to facilitate connection to corresponding external devices. The specific shape and size of the housing can be set and adjusted according to actual application requirements, and are not limited here.

[0036] Based on the technical solutions of the embodiments of this application above, multiple types of interfaces can be set on both the first and second sides, which is compatible with various types of peripheral interfaces; and the number of interfaces can be increased or decreased as needed, with strong scalability; each type of interface is provided in more than two, and the switching module can be controlled by the test terminal to realize the switching between interfaces of the same type, meeting the switching test requirements. At the same time, the switching module can also control the connection and disconnection between the interfaces on both sides to realize the plug-in test requirements. That is, the technical solution of this application can simultaneously meet the requirements of self-switching test and plug-in test, reduce manual intervention, reduce labor costs, and improve test efficiency; the device of this application is also provided with a control interface, which can be connected to the test terminal via TYPE-C or WIFI, and can be automatically controlled by the software of the test terminal, reducing manual switching and disconnection. The switching module features a cross-connected 1-to-2 splitter and 2-to-1 selector unit, enabling four data transmission channels between interfaces of the same type. Both the splitter and selector units utilize the same chip, allowing selection of either the first or second side as the input. Simultaneous data transmission from the first to the second side and vice versa provides bidirectional input and output, meeting the testing needs of multiple devices. Each side has at least two identical interfaces, replacing the physical plug-and-play functionality of the computer. The computer controls the opening and closing of the data transmission channels, enabling corresponding plug-and-play functions. The device includes a DC power supply unit, providing self-powered operation and plug-and-play functionality. Testing is controlled by the testing terminal, simplifying operation, reducing learning costs, and offering a simple and convenient structure.

[0037] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model.
