Description

Technical Field

[0001] The present invention relates to the technical field of data processing, and particularly to a port control device and method, a storage medium, and a terminal. Background Art

[0002] As more and more multimedia devices are connected to in-vehicle entertainment systems, users' requirements for the access ports in in-vehicle entertainment systems are also increasing.

[0003] Currently, some CPUs on the market have only one USB port, but some users hope that the in-vehicle computer can support two USB ports. This requires extending the USB to two paths through a USB HUB (port expansion device). However, there is a problem with the ports after expansion through the USB HUB. Since the current Apple mobile phone interconnection requires the use of an OTG interface, after expanding the USB port through the USB HUB, it will no longer be an OTG interface, and users can no longer use Apple mobile phone interconnection. Since the current market share of Apple mobile phones is relatively large, this will bring great inconvenience to users and even affect their choice of buying a car. Summary of the Invention

At this time, the first data signal subsequently sent by the processing module will be output through the first output end and the fifth path terminal of the second path conversion module. Since the transmission of the first data signal passes through the USB port expansion module, at this time, the first data signal can meet the dual-channel USB port transmission.

[0021] In addition, the first path conversion module closes the second path terminal and opens the first path terminal based on the second control signal; the second path conversion module closes the fourth path terminal and opens the third path terminal based on the second control signal. At this time, the second data signal subsequently sent by the processing module is only output through the fifth path terminal of the second path conversion module. Since the transmission of the second data signal does not pass through the USB port expansion module, at this time, the second data signal can meet the single-channel OTG port or USB port transmission.

[0022] In the port control method of the technical solution of the present invention, based on the first control signal, the first path end of the first path conversion module is closed and the second path end of the first path conversion module is opened; based on the first control signal, the third path end of the second path conversion module is closed and the fourth path end of the second path conversion module is opened, and the third path end is connected to the first path end; and a USB port expansion module is provided, the input end of the USB port expansion module is connected to the second path end, and the second output end of the USB port expansion module is connected to the fourth path end. At this time, the first data signal sent subsequently will be output through the first output end and the fifth path end of the second path conversion module. Since the transmission of the first data signal passes through the USB port expansion module, the first data signal can meet the dual-channel USB port transmission at this time.

[0023] In addition, based on the second control signal, the second path end of the first path conversion module is closed and the first path end of the first path conversion module is opened; based on the second control signal, the fourth path end of the second path conversion module is closed and the third path end of the second path conversion module is opened. At this time, the second data signal sent subsequently is only output through the fifth path end of the second path conversion module. Since the transmission of the second data signal does not pass through the USB port expansion module, the second data signal can meet the single-channel OTG port or USB port transmission at this time.

[0039] First, before step S101, it further includes: select the first instruction signal or the second instruction signal; send the first instruction signal or the second instruction signal.

[0040] In this embodiment, the processing module on the in-vehicle device generates an option interface for the first instruction signal and the second instruction signal, and the user selects the first instruction signal or the second instruction signal through the touch screen module on the in-vehicle device; after the user selects the first instruction signal or the second instruction signal, the first instruction signal or the second instruction signal is sent through the processing module on the in-vehicle device.

[0041] In this embodiment, the first instruction signal is a dual-USB port mode, and the second instruction signal is a single-OTG port mode.

[0042] In the specific implementation of step S101, the control module receives the first instruction signal and sends a first control signal after receiving the first instruction signal.

[0043] In the specific implementation of steps S102 and S103, based on the first control signal, the first path end of the first path conversion module is closed and the second path end of the first path conversion module is opened; based on the first control signal, the third path end of the second path conversion module is closed and the fourth path end of the second path conversion module is opened, and the third path end is connected to the first path end.
