Problems solved by technology

[0002] There are 3 sets of scrap steel trolleys in the stainless steel company, which are currently operated manually and are not equipped with positioning detection devices
Manual operation requires manual real-time observation of the running position of the car. The distance and angle of the trolley to be observed at the operating site, the stop position of the trolley is inaccurate, and sometimes the phenomenon of road blocking occurs, causing great damage to the equipment
[0003] The trolley positioning generally uses laser detection. The advantage of laser technology is accurate positioning, but relatively speaking, the cost is relatively high. The laser is in the same direction as the trolley. The site needs an open place that cannot block the laser, and the stainless steel site does not have the conditions

Abstract

The invention discloses an automatic positioning control system and control method for a steelmaking scrap steel platform car. The system comprises a platform car, a transmission motor, a supporting cable, a winding drum, a heavy hammer, an encoder, a PLC control unit and an operation box. The method comprises the following steps that: the platform car advances and retreats through the transmission motor, the platform car drives the winding drum to unwind a cable during advancing, and the heavy hammer controls the winding drum to wind the cable during the retreating of the platform car; the encoder collects cable unwinding and winding signals and transmits the signals to the PLC control unit; the PLC control unit calculates the running distance of the platform car by using a piecewise calibration function, segments the running range of the platform car to obtain the corresponding relationship between the output length of each section of the supporting cable and the actual position of the platform car, determines a corresponding correction coefficient; and finally the output lengths of the all sections of supporting cable are integrated, and the positioning control of the platform car is completed through the operation box. The method has the advantages of low investment cost and strong anti-interference capability, and can reduce the labor intensity of workers, shorten the operation time of the platform car and improve production benefits with production precision requirements met.

Description

technical field [0001] The invention belongs to the field of steelmaking automation control, and in particular relates to an automatic positioning control system and a control method for a steelmaking scrap steel platform vehicle. Background technique [0002] There are 3 sets of steel scrap trolleys in the stainless steel company, which are currently operated manually without positioning detection devices. Manual operation requires manual real-time observation of the running position of the trolley. The distance and angle of the trolley to be observed at the operating site is inaccurate. The stop position of the trolley is not accurate. [0003] Laser detection is generally used for trolley positioning. The advantage of laser technology is accurate positioning, but relatively speaking, the cost is relatively high. The laser is in the same direction as the trolley. The site needs an open location that cannot block the laser, and the stainless steel site does not have the con...
