An automatic positioning control system and control method for steelmaking scrap steel platform truck

Abstract

The invention discloses an automatic positioning control system and a control method for a scrap steel platform car for steelmaking. The system includes a flat car, a transmission motor, a pallet, a reel, a weight, an encoder, a PLC control unit, and an operation box. The method is as follows: The car advances and retreats through the transmission motor. The platform car drives the reel to unwind when it is moving forward, and the heavy hammer controls the reel to unwind when it is back. The encoder collects the release and roll signals and transmits them to the PLC control unit. The PLC control unit uses the segmental calibration function to calculate the running distance of the platform vehicle, divides the platform vehicle’s operating range into segments, and obtains the output length of each section of the pallet and the actual position of the platform vehicle. The corresponding relationship, determine the corresponding correction coefficient, and finally integrate the output length of each section of the pallet, and complete the positioning control of the platform vehicle through the operation box. The invention has low input cost and strong anti-interference ability. While meeting the requirements of production precision, the invention reduces the labor intensity of workers, shortens the operating time of the platform vehicle and improves production efficiency.

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...

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
