Description

A kind of multi-standard interface system

Technical field

It the utility model is related to a kind of interface circuit design technical field, and in particular to a kind of multi-standard interface system.

Background technology

Collecting device external interface generally has the demand of connection unlike signal attribute interface equipment, limited in physical connector In the case of, the quantity that can flexibly connect various criterion interface signal is to evaluate the important finger of collecting device using flexible Mark, but existing collecting device majority designs corresponding communication interface for physical interface, is running into a variety of things because needing to design Then need to carry a variety of collecting devices in the case of reason interface, it has not been convenient to onsite application.

The content of the invention

Goal of the invention：The utility model purpose is in view of the shortcomings of the prior art, there is provided a kind of multi-standard interface system, Various criterion interface can flexibly be connected.

Technical scheme：Multi-standard interface system described in the utility model, including processor, interface controller, N number of physics connect Mouthful, M communication interface of processor is configured as supporting the signaling interface of several agreement；The interface controller includes control Logic circuit, signal rows selection circuit, signal column select circuit, signal switching matrix circuit, the output interface of processor and control The driving port of logic circuit processed is connected, and control logic circuit is respectively connected with signal rows selection circuit, signal column select circuit For generating row selection signal, array selecting signal, signal switching matrix circuit is configured as M × N number of path, signal rows selection electricity Road, signal column select circuit are connected with signal switching matrix circuit for selecting M × N according to row selection signal, array selecting signal In physical interface described in corresponding communication and the signaling interface.

Above-mentioned technical proposal is further improved, the signal rows selection circuit corresponds to M communication interface and selected provided with M row Signal, the signal column select circuit correspond to N number of physical interface and are provided with N number of array selecting signal, and M, N are >=2 integer.

Further, M communication interface of the processor is configured as supporting the signaling interface of N kind agreements, and M is >=N Integer.

Further, the agreement that M communication interface of the processor is supported according to the physical interface is configured as Support the signaling interface of one or more of agreements in CAN BUS, RS485, RS232, RS422.

Beneficial effect：Compared with prior art, the utility model has the advantage of：Processor of the present utility model is according to thing Manage the interface attributes control interface controller connection respective communication interface signal of interfacing device.Control logic circuit is according to place The signal behavior requirement that reason device is sent sends a control signal to signal rows selection circuit, signal column select circuit, signal rows selection Circuit connects the signaling interface of respective protocol, signal column select circuit root according to row selection signal control signal switching matrix circuit Corresponding physical interface is connected according to array selecting signal control signal switching matrix circuit, realizes different attribute communication interface signal extremely The physical connection of physical interface, reach the purpose that port flexibly uses.The equipment that physical interface connects unlike signal attribute, such as pass Sensor, actuator etc..
