Transfer trolley positioning calibration device and calibration method thereof

Abstract

The invention belongs to the technical field of metal smelting, and particularly relates to a position calibration device of a transfer trolley for high-temperature melt. A calibration element group is arranged in a calibration section of a transfer path, the calibration element group comprises a positioning block and a communication tag which are adjacently arranged, and a proximity switch and a reader-writer are correspondingly arranged on the transfer trolley; if within the limited time range, the positioning system and the calibration system respectively collect signals to position the transfer trolley, whether positioning of the positioning system and the calibration system is matched or not is compared, and if yes, positioning of the transfer trolley is updated; and if not, the positioning system is corrected by taking the calibration system as the standard, and the positioning of the transfer trolley is updated. A positioning component different from an original signal acquisition mode is additionally arranged on a road section where the transfer trolley needs to be stopped accurately to calibrate an original positioning system, so that positioning errors of the transfer trolley caused by interference of foreign matters to the positioning system can be avoided, and use of the original positioning system is not affected; the function of accurately stopping the transfer trolley in place can be achieved at low cost on the basis of an existing positioning system.

Description

technical field [0001] The invention belongs to the technical field of metal smelting, and in particular relates to a position calibration device and a calibration method of a transfer vehicle for high-temperature melt. Background technique [0002] In the prior art, the slag ladle containing slag is usually transported by electric rail flat car. By setting calibration blocks between the tracks and photoelectric switches at the bottom of the transfer car, the position of the transfer car is collected when the transfer car moves to the calibration block. Information, and then control the start and stop of turnouts and transfer vehicles to realize the transfer of materials. In practical applications, other objects blocking the photoelectric switch will also trigger the collection of position information, causing the transfer vehicle's position information to be confused, causing the transfer vehicle to continue driving after passing the original stop position, or stop before r...

Problems solved by technology

In practical applications, other objects blocking the photoelectric switch will also trigger the collection of position information, causing the transfer vehicle's position information to be confused, causing the transfer vehicle to continue driving after passing the original stop position, or stop before reaching the target position, affecting production Efficiency, there are security risks

[0003] Chinese patent CN109099924A discloses a high-precision positioning algorithm for the driving of an electroplating production line. Three sensors are installed on the driving for simple addition and subtraction counting when running left and right to complete the most basic slot positioning. An RFID reader is also installed on the driving When the vehicle moves to the top of each slot, the card reader can read the RFID card installed above the slot, and each card has a unique ID number; before the vehicle moves, according to the RFID card reader The collected information corrects the sensor count. After the driving movement is over, check whether the driving vehicle has moved to the target position according to the information collected by the RFID card reader. However, during the driving movement process, only the sensor positioning is used, so that it can only be obtained when the driving stops. Accurate position, it cannot be accurately positioned during the driving process

In addition, the distance between the smelting furnace and the cooling area of ​​the high-temperature melt is relatively long, that is, the transfer path of the high-temperature melt transfer vehicle is long, and the long-term positioning system on the transfer path is expensive and difficult to maintain
