Description
Technical field
This utility model is specifically related to a kind of numeric type potentiometer.
Background technology
Along with Power Electronic Technique with control the developing rapidly of technology, potentiometer plays very important application in various industrial applications, as converter or current transformer control motor run time, its given speed is typically realized by Potentiometric devices.
Traditional resistor-type potentiometer changes the size of resistance by the knob on potentiometer, thus changes the current potential between Interposer contact and 0V joint.But, the resistive type potentiometer of the most traditional knob, the output current potential of potentiometer is difficult to accurately regulate, and causes control process the most loaded down with trivial details, and controls result pole inaccuracy；Meanwhile, traditional resistance potentiometer can not realize the amplitude limit of current potential, may cause the abnormal operation occurred due to artificial maloperation, jeopardize the safety of control system or life.
Utility model content
The purpose of this utility model is to provide a kind of current potential that exports can accurately control and numeric type potentiometer safe and reliable to operation.
This numeric type potentiometer that this utility model provides, including input module and control module；Input module and control module are sequentially connected in series；Input module is connected with control module, for providing input control signal to control module, it is achieved the operation to numeric type potentiometer, thus the output current potential of controlling potential device；Control module is for receiving the control signal of input module, and exports corresponding electrical potential information.
Described numeric type potentiometer also includes analog output module；Analog output module is connected with control module, for receiving the electrical potential information of control module, and exports corresponding current potential.
Described numeric type potentiometer also includes reseting module, and reseting module is connected with controller, is used for providing reset signal to numeric type potentiometer, and is resetted by numeric type potentiometer.
Described input module is button.
Described reseting module is button.
The button of described input module includes that level adds button and level subtracts button, and level adds button for controlling the rising of output level, and level subtracts button for controlling the decline of output level.
The model of described controller is CPU222CN.
The model of described analog output module is EM232.
This numeric type potentiometer that this utility model provides, uses the form of digital circuit and controller to realize the function of potentiometer, and therefore this utility model is capable of exporting the accurately control of current potential and amplitude limit controls, thus realizes the safe and stable operation of potentiometer；Additionally, this utility model uses general, ripe, stable industrial control unit (ICU) and industrial drives module to complete, therefore this utility model function-stable, reliability is high, can utilize the most easily or embed in other ripe industrial control systems.
Accompanying drawing explanation
Fig. 1 is the functional block diagram of first embodiment of the present utility model.
Fig. 2 is the functional block diagram of the second embodiment of the present utility model.
Detailed description of the invention
Being illustrated in figure 1 the functional block diagram of first embodiment of the present utility model: in this embodiment, numeric type potentiometer includes that level adds button, level subtracts button, SR, control module and analog output module；Level adds button, level subtracts button and SR is all connected in the digital-quantity input interface of control module, for providing the control signal of potentiometer；Control module receives the signal of load button by digital-quantity input interface, and is exported by analog output module by corresponding level information, thus ensure that the operation of numeric type potentiometer.The model of control module is CPU222CN, and the model of analog output module is EM232.
Being illustrated in figure 2 the functional block diagram of the second embodiment of the present utility model: in this embodiment, numeric type potentiometer includes that level adds button, level subtracts button, SR and control module；Level adds button, level subtracts button and SR is all connected in the digital-quantity input interface of control module, for providing the control signal of potentiometer；Control module receives the signal of load button by digital-quantity input interface, and exports corresponding level information；Now, control module is connected with target device by network, and therefore level signal directly can be exported to target device by control module by network.
When this utility model is specifically used, control module is changed by level corresponding in detection digital-quantity input interface, thus judges pressing and unclamping of button, thus realizes increase and the minimizing of output level；In addition, this utility model is as hardware platform, additionally it is possible to implement function such as: the level transformation period of control module monitoring digital-quantity input interface, and once level persistently changes, then control module control output level persistently changes, thus quickly changes output level；And, pass through control module, moreover it is possible to realize all types of defencive functions, such as output level amplitude limit etc..
