Specific embodiment
The specific embodiment of the present invention is illustrated below in conjunction with the accompanying drawings：
The invention provides a kind of slew gear control circuit and control method.Main purpose is as follows：
Control slew gear range of movement, wherein control circuit includes：Infrared emission pipe detects circuit, step motor drive
Circuit.The thin slice that infrared emission pipe real-time monitoring rotating mechanism side is installed, under normal operation, thin slice will not be by infrared emission
Pipe is detected.When rotating mechanism rotates to threshold value to a direction, infrared emission pipe holding wire is pulled low, and single-chip microcomputer is detected
Trailing edge, into interruption, Single-chip Controlling motor stops continuing to rotate to this direction, has ensured rotating mechanism mechanical part
Stable operation.
