To Haomei LB series asphalt mixing plant, the control system consists of two DELL business machines or self-developed control system, the next bit of the core system from the S7300PLC equipped with 16-bit AD module + high-speed transmission module heavy signal acquisition, to ensure the ingredients accuracy. For the construction of highways, airports, dams and other places. With a user-friendly interface, improved production data management, query and other functions. Production and ingredients process with real-time display of various data and animation display equipment operation and ingredients workflow. With the characteristics of easy access to the operation, simple and convenient, friendly man-machine interface, reliable operation, high precision ingredients. There are three parts in the whole control system of hot mix asphalt plant.

1. The computer control system

The computer is the man-machine dialogue of the whole control system, mainly realize the start and stop control of the equipment (issue control command), real-time monitoring equipment running status (including the production ingredients dynamic display, the real-time data and the amount of feed material, valve stroke display ...), data management (user rights management), recipe management, production management (production parameters, control parameters, ingredients parameters), production reports (daily production reports, comprehensive production reports), production records management, storage production data and query print various reports. The Computer control system mainly includes computer, display device, UPS, printer, serial card and so on.

2. The strong power cabinet

The strong cabinet adopt standard cabinet model with strong anti-interference ability. Distribution cabinet mainly install air circuit breakers, contactors, thermal relays, frequency converters, transformer trough terminals and other components. The door board is equipped with temperature controller, commutation switch and so on. Strong electrical appliances according to user needs to configure the import, joint venture or domestic brand products. Circuit design and selection meet the electrical standards, device installation and layout are reasonable, alignment is neat and easy to maintain.

3. Operator Station

My company console using human design style. Computer, monitor, control panel, printer and other components on the host part of the panel, the button is installed in the control panel of the protruding part of the table, the surface etching the panel logo which is intuitive and durable.
