Abstract

The invention discloses a special motor control system for an intelligent channel system and a control method. The motor control system comprises a main control circuit, a motor driving circuit, peripheral equipment and a detection module, wherein the main control circuit comprises a DSP (Digital Signal Processor) and an FPGA (Field Programmable Gate Array) processor; the motor driving circuit comprises a driving module and a semi-axle circuit; the peripheral equipment is connected with the FPGA processor by a third I / O isolation module, and comprises an infrared sensing module, an access module and a clutch module; and the detection module comprises a temperature sensor, a current detection module and a position detection module. According to the invention, by monitoring for the position, speed and current of a motor, adoption of a closed-loop feedback technology with a high-resolution encoder as well as optimization of speed setting and a acceleration curve, the starting speed is high, the stoppage is smooth, and the mechanical noise is reduced, so that the special motor control system can be applicable to occasions with very-frequent passage.

Description

technical field [0001] The invention relates to the technical field of motor control, in particular to a motor control system and a control method dedicated to an intelligent channel system. Background technique [0002] Traditional gates usually use AC motors or DC brushed motors. The power supply of AC motors is generally 220V strong electricity, which poses safety hazards to gates and has a slow response speed; the carbon brushes of DC brushed motors are vulnerable parts. , limited service life, not suitable for very frequent traffic occasions. The DC brushless motor can effectively avoid the above problems, but for the unique application of the gate, it is necessary to develop a special motor control system for the gate. Contents of the invention [0003] In order to overcome the deficiencies of the prior art, one of the objectives of the present invention is to provide a motor control system dedicated to the intelligent channel system, which monitors the position, sp...
