Abstract
The utility model discloses a kind of I/O module based on multiplex roles application, comprise a main structure body, this main structure body comprises input interface and output interface, and arranges expansion interface respectively in described main structure body both sides, described expansion interface one or more groups data transmission link external; Any connection RS422, CAN, the communication interfaces such as USB, only need provide communications protocol support on software, what increase the connected mode of module and other master controllers has multiple connected mode, meets the interactive correspondence mode of different external connection equipment or device, easy to use and flexible, structure is simply effective, is convenient to use in different field large-scale promotion.
Description
Technical field
The utility model relates to I/O module designing technique, is specifically related to a kind of I/O module based on multiplex roles application.
Background technology
I/O module and input/output module, for the print pin inputed or outputed carried when single-chip microcomputer run out after also need a kind of module of using during more print pin, object to be in order to the print pin number increasing input, export.
Traditional can only be connected on the exclusive application element thereof of manufacturer by proprietary connected mode.This mode just result in the underaction of connected mode, and versatility is deteriorated.Especially the comprehensive using forestland of most certificate or signal element at present, the I/O module of single face can not meet this demand.
Summary of the invention
The purpose of this utility model is to provide a kind of I/O module based on multiplex roles application.
According to one side of the present utility model, provide a kind of I/O module based on multiplex roles application, comprise a main structure body, this main structure body comprises input interface and output interface, and in described main structure body both sides, expansion interface is set respectively, described expansion interface one or more groups data transmission link external.
Especially, one or more groups RS series interfaces of described data line route, CAN interface, USB interface guide and connect.
Especially, described RS series interfaces comprises RS422 or/and RS232.
The beneficial effects of the utility model are: the I/O module based on multiplex roles application that the utility model provides connects RS422 arbitrarily, CAN, the communication interfaces such as USB, only need provide communications protocol support on software, what increase the connected mode of module and other master controllers has multiple connected mode, meets the interactive correspondence mode of different external connection equipment or device, easy to use and flexible, structure is simply effective, is convenient to use in different field large-scale promotion.
Accompanying drawing explanation
Fig. 1 is the structural representation of the I/O module based on multiplex roles application;
Fig. 2 is the another structural representation of the I/O module based on multiplex roles application.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Fig. 1 and Fig. 2 show schematically show according to a kind of I/O module based on multiplex roles application of the present utility model.
Embodiment 1:
As shown in Figure 1, comprise a main structure body, this main structure body comprises input interface and output interface, and arranges expansion interface respectively in described main structure body both sides, described expansion interface one or more groups data transmission link external.
One or more groups RS series interfaces of described data line route, CAN interface, USB interface guide and connect.Described RS series interfaces comprises RS422 or/and RS232.
Embodiment 2:
A kind of I/O module based on multiplex roles application that the present embodiment provides, as shown in Figure 2: comprise a main structure body, this main structure body comprises input interface and output interface, and any input interface and/or input interface are arranged expansion interface, described expansion interface one or more groups data transmission link external.One or more groups RS series interfaces of described data line route, CAN interface, USB interface guide and connect.Described RS series interfaces comprises RS422 or/and RS232.
Principle of work:
1, RS422 is connected arbitrarily, the communication interfaces such as CAN, USB;
2, only need provide communications protocol support on software, what increase the connected mode of module and other master controllers has multiple connected mode, meets the interactive correspondence mode of different external connection equipment or device;
3, easy to use and flexible, structure is simply effective, is convenient to use in different field large-scale promotion.
Finally should be noted that; above embodiment is only in order to illustrate the technical solution of the utility model; but not the restriction to the utility model protection domain; although done to explain to the utility model with reference to preferred embodiment; those of ordinary skill in the art is to be understood that; can modify to the technical solution of the utility model or equivalent replacement, and not depart from essence and the scope of technical solutions of the utility model.
