Angle valve

It has been widely used in ports, shipyards and other places because of its flexible and flexible steam exhaust muffler, easy to use, but how to effectively manage and accurately locate the wheel crane has always been a difficult problem. In order to improve the operation efficiency and save the operation cost of the port container yard, it is necessary to develop a set of high expansibility, high reliability and high intelligence management, scheduling, positioning, calibration and monitoring system of all relevant equipment in port container yard. The main technical parameters of the system are as follows: static positioning accuracy of 2cm, dynamic microporous muffler position accuracy of 5cm; using optimization algorithm to automatically generate cabin location map; using optimization algorithm to automatically discharge equipment operation box list; installing identification device on equipment spreader to automatically identify container number and generate yard location information; combined with GIS technology, 3D square is adopted Dynamic display of yard information. With the development of computer technology, great changes have taken place in the field of industrial control. The traditional control system with PLC as the core can not meet the needs of increasingly intelligent and distributed control. A stable, open, cheap and platform independent control platform is urgently needed to fill the gap of middleware. The industrial control platform based on middleware meets the requirements characteristic.
