Embodiment 1
[0014] Embodiment 1: The control device includes a stroke detector 1, a stroke given device 2, a speed detector 3, a speed given device 4, a DSP processor 5 and an output interface circuit 6, a stroke detector 1, and a stroke given device 2 , the speed detector 3, and the speed given device 4 are all connected to the input end of the DSP processor 5; the output end of the DSP processor is connected to the hoist power control system through the output interface circuit.
[0015] Control method: first use the position detector to detect the stroke of the coal mine hoist winch, so that the controller can control the position of the hoist; use the stroke detector to detect the stroke, use the speed detector to detect physical quantities such as lifting or lowering speed, and then use The physical quantity is collected in the signal level circuit for data sampling. After sampling, the voltage quantity is obtained, and the voltage quantity data is sent to the controller as the contro...
