[0002] The handheld operating terminal is a ground maintenance device for a certain airborne equipment. It communicates with the airborne equipment via an Ethernet interface and is used for functions such as door control, video mounting control, ground maintenance and inspection, online upgrades of airborne equipment, data download, and data parsing. After production, the handheld operating terminal requires functional testing. Due to its wide application and large market demand, traditional testing terminals can only test one handheld operating terminal at a time, resulting in low testing efficiency and significant pressure to meet delivery deadlines. Therefore, it is necessary to develop specialized automated testing equipment to achieve rapid testing of the handheld operating terminal.

[0016] The present application will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, only the parts relevant to the invention are shown in the accompanying drawings.

[0017] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0018] Please refer to Figure 1 This application provides a testing system for simultaneously testing multiple handheld operating terminals, including a test terminal, a USB expansion module, and an Ethernet-to-USB protocol processing unit. The Ethernet-to-USB protocol processing unit includes a USB interface and an Ethernet interface. One end of the USB expansion module is connected to the test terminal, and the other end has several interfaces, each of which is connected to a USB interface of the Ethernet-to-USB protocol processing unit. The Ethernet interface of the Ethernet-to-USB protocol processing unit is connected to the handheld operating terminal under test. The Ethernet-to-USB protocol processing unit is used to convert the Ethernet protocol into the USB protocol.

[0019] Specifically, the test terminal supports LCD screen and touch screen operation, the software interface of the test terminal supports the testing requirements of the functions and performance of handheld operating terminals, and the test terminal is mainly used for inputting test parameters and displaying the final test results.

[0020] Specifically, the USB expansion module uses a USB hub. Since test terminals typically only have 1-2 USB ports, this is insufficient to meet the requirement of simultaneously connecting multiple handheld terminals for testing. By setting up a USB hub, the test terminal's built-in USB port serves as the Host USB, and the multiple ports extended by the USB hub serve as Device USBs; the test terminal acts as the uplink port for USB communication, and the ports extended by the USB hub act as the downlink ports for USB communication. The number of ports extended by the USB hub can be adjusted according to the number of handheld terminals to be tested simultaneously; optionally, the USB hub can extend to 4 ports, numbered 1, 2, 3, and 4, thus creating 4 independent ports through 4 different port numbers.

[0021] Specifically, during testing, the Ethernet-to-USB protocol processing unit receives the test command from the test module, reframes the test command, and sends it to the handheld operating terminal. Upon receiving the reframed test signal, the handheld operating terminal analyzes and executes the corresponding command. Finally, the handheld operating terminal reports the execution result to the Ethernet-to-USB protocol processing unit via Ethernet. The Ethernet-to-USB protocol processing unit deframes the received execution result data frame and reports it to the test terminal via the USB interface.

[0022] Working Principle: A USB expansion module connects one test terminal to multiple handheld operating terminals, allowing one test terminal to send commands to simultaneously test multiple handheld test terminals, improving testing efficiency. The Ethernet-to-USB protocol processing unit converts the Ethernet protocol to the USB protocol, eliminating the IP and MAC addresses present in Ethernet data frames. During testing, the Ethernet-to-USB protocol processing unit converts Ethernet data frames to USB data frames, connecting upstream to a USB hub. The application layer distinguishes between these frames using the USB hub's port number, thus resolving IP conflict issues. The testing system provided in this application for simultaneously testing multiple handheld operating terminals has the advantages of simultaneously testing multiple handheld operating terminals and avoiding IP conflicts during testing.

[0023] In a preferred embodiment, an Ethernet PHY chip is further provided between the Ethernet protocol to USB protocol processing unit and the handheld operating terminal. One end of the Ethernet PHY chip is connected to the Ethernet interface of the Ethernet protocol to USB protocol processing unit, and the other end of the Ethernet PHY chip is connected to the handheld operating terminal.

[0024] Specifically, the Ethernet PHY chip is used to send and receive Ethernet data frames.

[0025] In a preferred embodiment, a network transformer is further provided between the Ethernet PHY chip and the handheld operating terminal. One end of the network transformer is connected to the Ethernet PHY chip, and the other end of the network transformer is connected to the handheld operating terminal through an RJ45 port.

[0026] Specifically, by setting up the network transformer, on the one hand, it ensures that when connected to different network ports, they will not affect each other's devices; on the other hand, it can also enhance the signal and isolate the Ethernet PHY chip from the outside, thereby improving anti-interference capabilities.

[0027] In a preferred embodiment, the Ethernet protocol to USB protocol processing unit includes a microprocessor, an Ethernet interface circuit, a USB interface circuit, a reset circuit, and a software protocol conversion circuit.

[0028] In a preferred embodiment, the USB interface of the Ethernet protocol to USB protocol processing unit supports the USB 2.0 protocol and is used to implement USB communication functions.

[0029] In a preferred embodiment, the Ethernet interface of the Ethernet-to-USB protocol processing unit supports the TCP / IP protocol.

[0030] Specifically, the Ethernet to USB protocol processing unit expands the hardware with 10 / 100M Ethernet and USB interfaces, and supports TCP / IP and USB 2.0 protocols in software, enabling speeds up to 480Mbps to meet communication requirements.

[0031] In a preferred embodiment, the Ethernet PHY chip is an 88E1111 chip.
