Interface multiplexing device and electronic equipment

Abstract

The invention is applied in the technical field of interface design, and provides an interface multiplexing device and electronic equipment. The device comprises a multiplex interface and a switching unit, wherein the multiplex interface is used for receiving transmission signals sent by external equipment; and the switching unit is used for identifying that the transmission signals are fast Ethernet signals or differential serial signals and establishing a signal channel between the multiplex interface and a fast Ethernet signal processing unit or a differential serial signal processing unit in a panel of the electronic equipment according to the identification result. According to the device, the type of the transmission signals is automatically identified by using level difference between the fast Ethernet signals and the differential serial signals, and the signal channel between the multiplex interface and the fast Ethernet signal processing unit or the differential serial signal processing unit in the panel of the electronic equipment is established according to the identification result, so that an interface multiplexing function is realized, the problem that the available space of the panel of the conventional electronic equipment is constrained is solved, possibility is provided for miniaturization of a product, and popularization and application of the electronic equipment are facilitated.

Description

technical field [0001] The invention belongs to the technical field of interface design, in particular to an interface multiplexing device and electronic equipment. Background technique [0002] In data communications, computer networks, and distributed industrial control systems, it is often necessary to use serial communication interfaces to exchange data with external devices, and to use Fast Ethernet (FE) interfaces to connect to Ethernet. Commonly used serial communication interfaces include RS-232 interface, RS-485 interface, RS-422 interface and so on. [0003] However, with the increase of functions of electronic equipment and the reduction of product size, the usable space of the panel in the electronic equipment is getting tighter and tighter, and even cannot accommodate the serial communication interface and the Fast Ethernet interface at the same time, so that the application range of the product is limited. Limitation is not conducive to the promotion and appli...
