Embodiment Construction

[0048] Specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0049] like figure 1 As shown, the DC motor control system of the present embodiment includes a processor 01, a driver 02, an extended position proximity switch 12, a received position proximity switch 13 and a current sensor 11, wherein:

[0050] The processor 01 is used to receive the acquisition signal, and form a control signal and an alarm signal according to the built-in control strategy;

[0051] The driver 02 is used to receive the control signal, form a corresponding electric power signal and output it to the DC bus;

[0052] The current sensor 11 is used to collect the current change signal of the DC bus that outputs the electric power signal and transmit it to the processor;

[0053] The proximity switch 12 is extended to the position, and is used to generate a trigger signal when the actuator 04 is extended to the position, and t...

Abstract

The safe and reliable DC motor control system of the present invention includes a processor, a driver, an extended position proximity switch, a received position proximity switch and a current sensor, wherein: the processor is used to receive acquisition signals and form control signals and alarms according to built-in control strategies signal; the driver is used to receive the control signal and form the corresponding electric power signal to output to the DC bus; the current sensor is used to collect the current change signal of the DC bus that outputs the electric power signal and transmit it to the processor; The trigger signal is generated when the actuator reaches the position and sent to the processor; the proximity switch is used to generate a trigger signal when the actuator receives the position and is sent to the processor; the driver drives the connected DC motor to drive the actuator to form a linear motion. Provides six types of real-time data that can be used for intelligent judgment with preset data. A control method is also provided.

Description

technical field [0001] The invention relates to an electromechanical control system and a control method, in particular to a control system and a control method of an electric motor. Background technique [0002] The DC motor is used as the power to drive the actuator to perform linear motion through the conversion mechanism, which is a common method for DC motors. Compared with the hydraulic system drive, the DC motor drive method is cleaner, and can be easily disassembled with the actuator, and there will be no problems such as oil intake and oil pollution caused by the disassembly of the hydraulic pipeline. It is suitable for use in The power is not large or the actuator has to be disassembled and used. The DC motor receives the power signal of the driver through the DC bus to generate movement. Usually, two in-position sensors are set at the two limit positions of the actuator driven by the DC motor, and two in-position sensors are set. When the action is in place, the ...
