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...

Abstract

A three-stage speed given mine hoist control method and device, the stroke detector, stroke giver, speed detector, and speed giver of the control device are all connected to the input end of a DSP processor; the DSP processor The output terminal of the hoist is connected with the hoist power control system through the output interface circuit. The control method uses the position detector to detect the stroke of the coal mine hoist winch, so that the controller can control the position of the hoist; the stroke detector is used to detect the stroke, and the speed detector is used to detect physical quantities such as lifting or lowering speed, and then the detected physical quantity Data sampling is carried out at the signal level loop summary, and the voltage data obtained after sampling is sent to the controller as the control basis. Advantages: This device adopts the three-stage speed given hoist control method with feedback within the stroke, which has fast lifting speed, high control precision, simple structure and convenient operation.

Description

technical field [0001] The invention relates to a mine hoist control device, in particular to a three-stage speed-given mine hoist control method and device based on in-stroke feedback. Background technique [0002] The hoist is responsible for the lifting of minerals, the up and down of personnel, the transportation of materials and equipment in the mine, and plays a very critical role in mine production. To control the running speed of the hoist, there must be a reliable control reference signal determined according to the speed requirement, that is, the "speed given signal" in the adjustment system, in order to ensure safe and accurate completion of the lifting task. At present, domestic hoists Most of the power braking and speed regulating systems use time given v=f(t), and the given reference is a function of time (the deceleration point is still given by a set stroke). As far as the time setting method is concerned, when there is a static error in the actual speed con...
