Description
Technical field
The present invention relates to a kind of intelligent electric executer control systems, and in particular to a kind of high-precision control intelligent electric
Dynamic actuator control system.
Background technology
Existing intelligent electric executer adjustment control method is by the current position of given control signal and actuator
Signal is compared, and when error is more than certain value, driving motor acts, and motor control is disconnected when error is less than certain value makes electricity
Machine stops, however different capacity motor inertia is different, and inertia is larger when especially power is larger, therefore cannot reach higher
Control accuracy.
General AC motor brake mostly uses reversing braking, that is, to the reverse drive of one short time of motor when stopping, allows
Motor stops, but this mode of braking braking effect is unreliable, and consistency is poor, is damaged to motor big.
AC power can not be often provided in some remote districts, but direct current can be provided by solar power generation
Source, it is therefore desirable to which Electric Actuator power supply uses direct current supply.To realize that Electric Actuator can be powered using DC power supply, need
Redesign internal control system.
Invention content
In order to solve the above technical problem, the present invention provides a kind of controls of high-precision control intelligent electric executer to be

Brake units, display unit and remote control signal conversion unit are connect with main control unit, electric-motor drive unit and motor brake list
Member is connect with direct current generator, and electric-motor drive unit is connect with motor brake unit, the directly external direct current of electric-motor drive unit
Source, power conversion unit external direct current power supply.
DC power supply is solar powered DC power supply.
It is a based on ARM Cortex-M that the main control unit, which uses STM32F103C8T6 microcontrollers, STM32F103C8T6,
32 microcontrollers of kernel STM32 series, program storage capacity are 64KB, and operating temperature is -40 °C ~ 85 °C, can
Adapt to most of environment.
The knob of intelligent electric executer is mounted on operation panel, to be carried out to intelligent electric executer
Parameter setting and the manual operation of open and close valve, knob detection unit is to detect knob position, to obtain corresponding ginseng
Number；Torque test unit is detecting torque；Valve position detection unit is detecting valve position；Remote control signal conversion unit receives control
Signal simultaneously converts the control signal received；Electric-motor drive unit is controlled by main control unit, drives direct current generator；Motor is stopped
Vehicle unit is controlled by main control unit, realizes direct current generator braking.
Display unit uses touch screen, display unit to cannot be only used for showing, also can carry out manual setting by it.
Above system directly uses DC power supply to power, and in control, realizes motor braking by motor brake unit, no
Need inverter that DC power supply is become AC power, it is simple in structure, efficient, save cost for user.
The above is only a preferred embodiment of the present invention, it is noted that for the ordinary skill people of the art
For member, without departing from the technical principles of the invention, several improvement and deformations can also be made, these improvement and deformations
Also it should be regarded as protection scope of the present invention.
