Description
[technical field]
The utility model relates to electrical equipment, particularly relates to a kind of multiplex roles magnetic rotation type potentiometer.
[background technology]
Be applied to the turn knob potentiometer rotating regulation and control at present and can be divided into mechanical type, resistance-type, condenser type, induction etc., wherein mechanical type and resistance-type mostly are turning axle and contact with rotary body, this mode requires high for design accuracy, measuring accuracy is low, and easily wear-out life is shorter, is applicable to some more and lower occasion is required to measuring accuracy.Condenser type and electromagnetic type are generally turning axle and rotary body noncontact, therefore long service life, but measurement by capacitance precision is low, larger by such environmental effects.
[utility model content]
The purpose of this utility model is to provide a kind of multiplex roles magnetic rotation type potentiometer, is intended to solve potentiometer life-span short problem.
The utility model realizes like this, a kind of multiplex roles magnetic rotation type potentiometer, this potentiometer combines primarily of sensor, control module, output module, and described sensor is connected with described control module one end, and the described control module other end connects described output module.
Further technical scheme of the present utility model is: described sensor mainly comprises bipolar magnet and Hall element, and described bipolar magnet is arranged on described Hall element.
Further technical scheme of the present utility model is: described bipolar magnet is cylindrical knob.
Further technical scheme of the present utility model is: described control module combines primarily of filtering circuit and MCU.
Further technical scheme of the present utility model is: described output module comprises multiple output interface.
Further technical scheme of the present utility model is: described output interface mainly comprises: USB interface, RS485 interface, RS232 interface, CAN.
The beneficial effects of the utility model are: potentiometer of the present utility model is based on electromagnetic induction principle and communication interface technique, there are high precision 360 ° of scopes measure, long service life, long distance of signal transmission, antijamming capability is strong, the turn knob potentiometer that power consumption is lower, this utility model has polytype interface simultaneously, greatly facilitates the routine use of people.
Accompanying drawing explanation
Fig. 1 is a kind of multiplex roles magnetic rotation type potentiometer system structural drawing that the utility model embodiment provides.
[embodiment]
Fig. 1, show the system construction drawing of a kind of multiplex roles magnetic rotation type potentiometer that the utility model provides, this potentiometer is primarily of sensor 1, control module 2, output module 3 combines, described sensor 1 is connected with described control module 2 one end, it is fast that described control module 2 other end connects described output mould, described sensor 1 mainly comprises bipolar magnet and Hall element, described bipolar magnet is arranged on described Hall element, further technical scheme of the present utility model is: described bipolar magnet is cylindrical knob, further technical scheme of the present utility model is: described control module 2 combines primarily of filtering circuit and MCU, further technical scheme of the present utility model is: described output module 3 comprises multiple output interface, further technical scheme of the present utility model is: described output interface mainly comprises: USB interface, RS485 interface, RS232 interface, CAN, this utility model forms primarily of three parts: sensor 1 part, control module 2 and output module 3 form, and wherein sensor 1 module adopts the sensor based on hall principle, is made up of rotation bipolar magnet and hall sensing device.Rotary pole and the noncontact of hall sensing device, wherein hall sensing device is small package integrated device, exportable digital signal and simulating signal; Control module 2 is made up of filtering circuit and MCU control unit, and filtering circuit carries out filtering to power circuit and analog output signal, and digital signal can directly be processed by low-power consumption MCU unit.Output module 3 can outputting analog signal and digital signal; Wherein analog signal output can be voltage signal can be also current signal, and digital signal is transmitted by RS485 and USB interface; In the program, bipolar magnet is fixed in rotating shaft, just to hall sensing device, and both noncontacts.Hall sensing device can sense the rotation of bipolar magnet, can the position of rotation of accurately perception bipolar magnet within the scope of 360 °, and exporting different analog voltage signals or digital signal according to the position of rotation of magnet, digital signal is directly transferred to MCU by I2C interface; The signal of sensor 1 carries out dissection process in MCU, then can outputting analog signal or digital signal through output processing circuit, and exports through different interfaces; Simulating signal adopts voltage signal and current signal to export, digital signal can pass through USB interface, RS485 interface, RS232 interface, the output of CAN interface, this signal transmission form has long transmission distance, the features such as antijamming capability is strong, therefore the placement of this knob is relatively more flexible, and the scope of application is wider.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., all should be included within protection domain of the present utility model.
