Gantry crane control system solutions

gantry crane actuator work required frequent start, braking and reversing, thus requiring its electronic control system has high security and reliability. Traditional electric control system, due to consider the complex inter-agency working condition interlock and protection alarm, using a lot of time relays and relay, the control cabinet wiring is very complicated, to commissioning and maintenance inconvenience. Adopts PLC as controller, you can replace the PLC timer time relay, with the software programming to achieve inter-agency and multi-interlock protection alarm. Greatly reduces the intermediate relay, making it simple to design the system to improve the electrical control reliability. In addition, the PLC can also be achieved through the control of the inverter and the complex process requirements.  bridge gantry crane  PLC main control functions are: to accept the master controller speed control signal to control the crane walking, lifting movement and speed control. (A) safety interlock and protection of newspaper and other signal processing. (2) lifting, running gear synchronization control (3) hoists detection and closed-loop control (4) Auxiliary systems and power distribution system monitoring 1.3.2 crane monitoring system as microelectronics, computer and control technology continues to push New, PLC has developed into a versatile, intelligent integrated controller. their application not only to achieve automatic control of the production process, but also constitutes a real-time network for industrial environments, allowing the system to a single PLC control extends to large industrial networks dispersion devices, PLC link communication network, to achieve a large number of high-speed data transmission and management, through the SCADA / HMI SCADA management software enables the operation of the  hoist crane  intelligent management SCADA management software's main functions are: ( 1) Online functions: real-time display operating status, graphic simulation, user-friendly interface for easy operation. (2) failure alarm (3) Automatic monitoring interlock function (4) historical maintenance data records (5) operating statistics and records (6) help function (7) System Report: The system can achieve fault statistics and print reports, operational reports , repetitive failure rate and other relevant data reports.
