Description
Technical Field
The utility model relates to a test equipment field, concretely relates to USB3.0 opens short circuit test equipment.
Background
Whether the normal transmission data test of the USB3.0, USB2.0 interface, connecting wire and other low-speed, full-speed, high-speed and USB3.0 ultra-high speed signals in the equipment such as PC mainboard, notebook computer, wire rod, USB3.0, USB2.0 concentrator detects normally, the traditional USB test equipment almost adopts the equipment that connects PC equipment or connects through USB3.0 concentrator and has USB2.0 and USB3.0 functions, the cable connection interface enumerates the test equipment, the test time is longer, the operation is more tedious and the test result can only be judged by people, the production test efficiency is low, and the stability is poorer.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a USB3.0 opens short circuit test equipment for USB3.0 among the solution prior art opens short circuit test equipment problem.
The utility model provides a USB3.0 opens short circuit test equipment, including controller, switch module and three interface, three interface is USB2.0&3.0HOST, USB2.0&3.0DEVICE and USB3.0-B interface respectively, USB2.0&3.0HOST, USB2.0&3.0DEVICE all connect the switch module, switch module connection director, USB3.0-B interface is connected to the controller.
Further, the controller is also connected with an LED.
Further, the controller is STM32F103C8T 6.
Adopt above-mentioned the utility model discloses technical scheme's beneficial effect is:
the utility model discloses USB3.0 opens short circuit test equipment and carries out signal detection and judges whether normal to the USB interface, and the interface automatic test, the test result directly shows at operation interface, does not need the user to make a judgement result by oneself; the method has the advantages that the USB3.0 and the USB2.0 are automatically detected, and a universal USB 3.0/USB2.0 Host Controller can be supported; and displaying the test result after the test is completed: PASS or FAIL, and record the test state of the port, after the test is finished, automatically generate a test log record file and a result receipt file.
Drawings
FIG. 1 is a schematic structural view of a USB3.0 open/short circuit test device of the present invention;
Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention.
As shown in FIG. 1, the utility model provides a USB3.0 opens short circuit test equipment, including controller, switch module and three interface, three interface is USB2.0&3.0HOST, USB2.0&3.0DEVICE and USB3.0-B interface respectively, USB2.0&3.0HOST, USB2.0&3.0DEVICE all connect the switch module, switch module connection director, USB3.0-B interface is connected to the controller. The working flow of the embodiment is as follows; the user connects the USB open-short circuit test Device to the USB port (USB Host) of the Device to be tested, enumerates in the Device manager of the operating system, and detects the enumerated Device (USB Device) and the USB port under the system by matching with the test program, wherein in the USB connection relationship of the Device to be tested in the prior art, USB3.0 comprises SS channels, HS channels, FS channels and LS channels, wherein the SS channels and the Non-SS channels are relatively independent. When testing the USB function, the SS channel and the Non-SS channel need to be tested respectively; the method realizes the functional test of the USB equipment type, the working mode and the open and short circuit of the data transmission interface.
Preferably, the controller is further connected with an LED, and the LED display screen displays the test result: PASS or FAIL.
Specifically, the controller is STM32F103C8T 6.
To sum up, the utility model discloses USB3.0 opens short circuit test equipment and carries out signal detection and judge whether normal to the USB interface, and the interface is automatic to be tested, and the test result directly shows at operation interface, does not need the user to make a judgement result by oneself; the method has the advantages that the USB3.0 and the USB2.0 are automatically detected, and a universal USB 3.0/USB2.0 Host Controller can be supported; and displaying the test result after the test is completed: PASS or FAIL, and record the test state of the port, after the test is finished, automatically generate a test log record file and a result receipt file.
Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention, and not to limit the same; although the present invention has been described in detail with reference to the foregoing embodiments, it should be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some or all of the technical features may be equivalently replaced; such modifications and substitutions do not depart from the spirit and scope of the present invention.
