2results about How to "Fast correction" patented technology

This utility model discloses a tool for locally bending and leveling angle steel, including a worktable, a pad fixedly connected to the top of the worktable, and a hammer placed above the pad. The tool also includes a driving device mounted on top of the hammer. This utility model relates to the field of metal processing technology. Through the cooperation of a support rod, a fixing frame, and a reciprocating assembly, the fixing assembly secures the angle steel to the top of the worktable. Driven by the reciprocating assembly, the hammer repeatedly strikes the bent area of ​​the angle steel, thereby straightening it. This device occupies little space and accelerates the straightening process. It solves the problems of hydraulic straightening machines, which, while providing good leveling results, are large, heavy, inconvenient to move, and expensive. They are only suitable for overall straightening of large batches of large-sized angle steel, and for small-area, localized bending and leveling, they are cumbersome to operate, energy-intensive, and lack flexibility.

A CAN bus urea quality sensor concentration correction system and method are disclosed. The CAN bus urea quality sensor concentration correction system includes a urea quality sensor body and a quality concentration probe disposed at the lower end of the urea quality sensor body. The quality concentration probe has a emitting surface and a reflective surface spaced apart from the emitting surface. The CAN signal interface of the urea quality sensor body is electrically connected to a USB-CAN analyzer via a CAN bus. The serial port of the USB-CAN analyzer is electrically connected to the serial port of a host computer. This invention corrects the distance between the emitting and reflective plates of the urea quality sensor through closed-loop compensation data fitting, making the urea concentration measured in a standard urea solution at room temperature more accurate. By integrating concentration measurement data under other temperature and concentration conditions through a large amount of experimental data, the measurement accuracy of the ultrasonic probe product is significantly improved. No additional components are required, and the correction speed is fast, exhibiting high correction accuracy and practicality.
