Technical field
The present invention relates to automation field, relate to a kind of actuator control system in particular.
Background technology
Actuator (final controlling element) is receiving control information apply the device of control action to controll plant in automation equipment.It act as the control signal receiving controller and export, and controls controll plant according to this control signal.
The pin assignment of the controller of current actuator is nervous, thus can not realize the expansion of other functions.
Summary of the invention
In view of this, the present invention openly provides a kind of actuator control system, to realize the Function Extension of controller.
For achieving the above object, the invention provides following technical scheme:
A kind of actuator control system, comprising:
Controller;
Be connected with the output pin of described controller actuator, for receiving the control signal that described controller exports, and controls controll plant according to described control signal;
The A/D converter be connected with the input pin of described controller, described A/D converter comprises multiple input pin;
The multiple control circuits be connected with described A/D input pin, for passing through described A/D converter to described controller input control signal.
Preferably, described controller is STC89C58RD single-chip microcomputer.
Preferably, described A/D converter is the A/D converter of MCP3204 model.
Preferably, described control circuit is key scanning circuit.
Through as shown from the above technical solution, the present invention openly provides a kind of actuator control system.This control system comprises controller, the actuator be connected with controller output pin, is connected with controller input pin, and has the A/D converter of multiple input pin and the multi-channel control circuit that is connected with multiple input pins of described A/D converter.The input pin of A/D converter to controller by having multiple input pin in the present invention is expanded, thus enables controller receive the different control signals of multiple control circuit output, expands the functional realiey of controller.
Accompanying drawing explanation
In order to be illustrated more clearly in the embodiment of the present invention or technical scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only embodiments of the invention, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to the accompanying drawing provided.
Fig. 1 has gone out the structural representation of an embodiment of a kind of actuator control system of the present invention.
Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, be clearly and completely described the technical scheme in the embodiment of the present invention, obviously, described embodiment is only the present invention's part embodiment, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtained under creative work prerequisite, belong to the scope of protection of the invention.

It should be noted that, described controller is STC89C58RD single-chip microcomputer.Described A/D converter is the A/D converter of MCP3204 model.
As known from the above: the present invention openly provides a kind of actuator control system.This control system comprises controller, the actuator be connected with controller output pin, is connected with controller input pin, and has the A/D converter of multiple input pin and the multi-channel control circuit that is connected with multiple input pins of described A/D converter.The input pin of A/D converter to controller by having multiple input pin in the present invention is expanded, thus enables controller receive the different control signals of multiple control circuit output, expands the functional realiey of controller.
Finally, also it should be noted that, in this article, the such as relational terms of first and second grades and so on is only used for an entity or operation to separate with another entity or operational zone, and not necessarily requires or imply the relation that there is any this reality between these entities or operation or sequentially.And, term " comprises ", " comprising " or its any other variant are intended to contain comprising of nonexcludability, thus make to comprise the process of a series of key element, method, article or equipment and not only comprise those key elements, but also comprise other key elements clearly do not listed, or also comprise by the intrinsic key element of this process, method, article or equipment.When not more restrictions, the key element limited by statement " comprising ... ", and be not precluded within process, method, article or the equipment comprising described key element and also there is other identical element.
In this instructions, each embodiment adopts the mode of going forward one by one to describe, and what each embodiment stressed is the difference with other embodiments, between each embodiment identical similar portion mutually see.
To the above-mentioned explanation of the disclosed embodiments, professional and technical personnel in the field are realized or uses the application.To be apparent for those skilled in the art to the multiple amendment of these embodiments, General Principle as defined herein when not departing from the spirit or scope of the application, can realize in other embodiments.Therefore, the application can not be restricted to these embodiments shown in this article, but will meet the widest scope consistent with principle disclosed herein and features of novelty.
