With the vigorous development of shipbuilding industry, the application of large span and large tonnage shipbuilding beam gantry crane is more and more widely. In view of the working conditions and control technical requirements of this kind of crane, the requirements for its electrical control performance, speed adjustment accuracy, safety and reliability are higher and higher. With the increasing development of electrical control technology, frequency conversion speed regulation, encoder deviation correction and PLC complex operation are gradually applied in large span and large tonnage cranes. The following is a systematic description of the design scheme of mg300t * 46m double girder gantry crane electrical system.

ABB Inverter supports Modbus RTU protocol when it works normally. As a slave station of Modbus RTU, Siemens 300plc of monitoring center system supports PROFIBUS DP protocol. As a master station of DP, the two protocols are different, so data exchange can not be realized by direct communication. Data exchange between different protocols can only be realized by a third-party protocol conversion module. In this case, the general serial port to profibusdp gateway pm-160 developed and produced by Shanghai Sibo Automation Technology Co., Ltd. is used to realize the conversion of ModbusRTU protocol to profibusdp protocol, so as to realize the real-time monitoring and control of ABB inverter output frequency, start stop, forward and reverse parameters through Siemens 300plc, Ensure that the monitoring center system can monitor the status of ABB Inverter remotely and control the start and stop of inverter.Most of the stacking shapes of robots need robot engineers to go to the site to program and debug according to the requirements of stacking shapes. Each stacking shape needs an independent program, which is time-consuming and laborious. And the requirements for debugging personnel are high, people without programming skills can not complete debugging. As a standard or semi-standard equipment company, it needs a set of standard palletizing procedures, and it can complete palletizing debugging without professional robot engineers.

In recent years, with the development of automation control technology, computer technology, communication, network and other technologies, the field of information interaction and communication is rapidly covering from the field equipment layer of the factory to all levels of control and management. Therefore, more and more factory automation systems adopt the system structure of device bus, distributed control and centralized information management. This structure greatly reduces the project investment, effectively enhances the development and maintainability of the system, and shortens the design and development cycle. Allen Bradley's ControlLogix System is a high-tech product developed in accordance with this development direction. It provides complete processor specifications, powerful supporting function modules and tool software, and is suitable for various applications of medium to large-scale systems.

The automation control system used in PVC production line of the plant is the concrete application of Allen Bradley ControlLogix System, ControlNet, DeviceNet, flex I / O, remote I / O (Rio) and other new technologies. The system integrates program control, process control and working condition monitoring, and realizes the computer monitoring and control of the whole workshop process line.
