The rotary encoder is connected with the single-chip computer controller which is connected with the digital potentiometer, the serial communication receiving end, the serial communication transmitting end and the display driver, and the display driver is connected with the LED display. Controlling signals of a remote controlling device are transmitted to the single-chip computer controller through the serial communication receiving end, and the rated voltage ratio of the digital potentiometer is controlled by the single-chip computer controller. The numerical value signals is provided for the display driver by the single-chip computer controller, displayed by means of the LED display, and transmitted to the remote controlling device by the single-chip computer controller through the serial communication transmitting end, and thereby remote interaction controlling is realized.
Description
Technical field
The utility model belongs to technical field of electronic equipment, particularly is applicable to the technical field of electronic product.
Background technology
The simulation potentiometer is a kind of adjustable electronic component, and it is rotated by a resistive element and one or sliding system is formed.When adding a voltage between two fixed contacts of resistive element, by rotating or sliding system changes the position of contact on resistive element, between moving contact and fixed contact, just can obtain one and become the voltage that necessarily concerns with the moving contact position.It is to use as voltage divider mostly, is connected with the amplifier of fixed gain, as long as change the voltage ratio of voltage divider, can change the output voltage of amplifier, referring to accompanying drawing 1; Continual renovation along with science and technology, digital regulation resistance has been born, it is a kind of solid-state potentiometer, it is different fully with operation principle, structure, the profile of traditional simulation potentiometer, it has cancelled movable part, be a semiconductor integrated circuit, its advantage is promptly to have kept the function of simulation potentiometer not have noise again, and extremely long working life is arranged.Referring to accompanying drawing 2.But, digital regulation resistance does not promptly have remote control function, there is not the numerical value display system yet, can not be connected and be controlled by control appliance with remote control equipment, can not timely its value corresponding be shown, therefore, in the scientific and technological epoch of present high speed development, just the demand in market can not have been satisfied.
The utility model content
The utility model is intended to overcome the prior art defective, on existing digital regulation resistance basis, add singlechip controller, rotary encoder, light-emitting diode display, display driver and serial communication receiving port and serial communication transmit port, form a kind of novel potentiometer with remote interaction control and Presentation Function.
The purpose of this utility model is achieved through the following technical solutions: a kind of novel potentiometer with remote interaction control and Presentation Function comprises: provide the rotary encoder of voltage ratio signal to singlechip controller, the singlechip controller and the digital regulation resistance of control signal is provided to digital regulation resistance; It is characterized in that: this novel potentiometer with remote interaction control and Presentation Function also comprises light-emitting diode display and the display driver thereof that serial communication receiving terminal and serial communication transmitting terminal and responsible numerical value show; Wherein, rotary encoder links to each other with singlechip controller, and singlechip controller links to each other with serial communication transmitting terminal and display driver with digital regulation resistance and serial communication receiving terminal respectively, and display driver links to each other with light-emitting diode display.
Remote control equipment is connected with the serial communication transmitting terminal with the serial communication receiving terminal of this device, control signal from remote control equipment just can be delivered to singlechip controller to signal by the serial communication receiving terminal, come the size of control figure potentiometer voltage ratio by singlechip controller, simultaneously singlechip controller offers display driver with the magnitude numerical value signal of voltage ratio and shows by light-emitting diode display, by the serial communication transmitting terminal, singlechip controller sends to remote control equipment with numerical signal, and then has realized remote interaction control; When not needing Long-distance Control, can provide the voltage ratio signal to singlechip controller by rotary encoder, come the size of control figure potentiometer voltage ratio by singlechip controller; Simultaneously singlechip controller offers display driver with the magnitude numerical value signal of voltage ratio and shows by light-emitting diode display.
Compared with prior art, the invention has the beneficial effects as follows: on the basis that keeps the digital regulation resistance function, increased remote interaction control and Presentation Function, made that use, debugging and management are more flexible.
