Description

Technical Field

[0001] The invention belongs to the technical field of debuggers, and in particular relates to an integrated multi-interface debugger based on USB conversion. Background Art

[0002] With the development of the Internet of Things and information technology, IT developers and on-site operation and maintenance personnel are increasingly exposed to hardware devices in their daily work, and there are various types of different devices and human-computer interaction interfaces. In order to meet the development and on-site operation and maintenance debugging work, the staff needs to prepare different debuggers for different device interfaces to connect the working PC with the target hardware device, mainly to complete the docking on the physical interface and the conversion of communication level signals.

[0003] There are three main types of debuggers available on the market. The first type is a connection cable, which only provides a physical interface between a personal PC and a target device. It can be directly connected without level conversion, such as a serial cable, an Ethernet cable, etc. The second type is a connection cable based on USB conversion, which converts the physical interface and communication level and can be directly connected, but the interface is relatively simple, such as a USB to serial cable and a USB to RS485 cable. The third type is a USB-based converter, which converts the physical interface and communication level, but does not have an integrated docking cable and cannot be directly connected.

[0004] However, the three debuggers currently have some problems and shortcomings. The first is that with the miniaturization of PCs, some previous communication interfaces have been gradually replaced, such as the DB9 serial port and the RJ45 network port, resulting in the physical interface on one end of the connection cable no longer being compatible; the second is that although it is based on the currently popular USB port for conversion, its function is relatively simple, and different device interfaces require different debuggers; the third is based on USB conversion, integrating a variety of adapters, but there is no integrated cable, and it cannot be directly connected and used. In short, none of the three debuggers have achieved multi-interface and integrated universality. Therefore, how to overcome the shortcomings of the existing technology is an urgent problem to be solved in the field of debugger technology. Summary of the invention

[0005] The purpose of the present invention is to solve the deficiencies of the prior art and to provide an integrated multi-interface debugger based on USB conversion, which integrates an integrated cable, meets the device debugging requirements of most hardware, improves work efficiency and user experience, and is easy to promote and apply.
