The Intelligent Distributed Control System connects all the intelligent NC severs for all single machines on a production line, by way of field bus or industrial Ethernet, using PLC and IPC as main control units, to achieve centralized automatic control and intelligent monitoring for the whole production line.
Principle Functions for theIntelligent Distributed Control System：
Secure Startup Function: One-key startup, sequential startup,step-down startup,linkage control, etc. All this functions contribute to a safer and more reliable startup of the machines for a production line.
Automatic Coordination of Equipment Workload: System will adjust the feeding frequency for primary crusher automatically based on the inventory situations; and the subsequent machines will adjust their own workload automatically according to the primary crusher workload. Thus the system can adjust the working mode for the whole production line automatically and flexibly. In a result, waste of electricity power can be eliminated and production cost can be reduced.
Real Time Monitoring on Production Status: Real time monitoring on the equipment working status, product output, warehouse inventory, etc., specifically including main motor current, equipment workload, bearing temperature, liner abrasion, belt conveyor output, hydraulic pressure, travel of spindle, oil temperature, machine vibration, spindle speed, material level for warehouse, position of unloading belt, warehouse input/output/inventory, arc gate state, stock for the loading bins, and so on. All these data is the foundation for further intelligent functions such as automatic control, fault prognosis, fault diagnosis, big data analysis etc., of the IoT management system.
Video Surveillance Function: It means video surveillance for critical monitoring points for the whole production field as needed, including feeding ports for the crushers, surge bins, discharge openings for the crushers, the central control room, the warehouses, loading area, as well as the surrounding environment, so that the operator in the control room can grasp the overall situations and equipment working status outside visually, comprehensively, and conveniently via the big TV screen in the control room.
Parameter Setting Function: The safe operating range for the parameters of the equipment can be set up as needed in advance, to support functions like fault prognosis, auto-shutdown, linkage control, etc. There are two general lines for each kind of parameter. The“Upper-Limit”and “Lower-Limit”are for common kinds of alarm, and the machine will not be stopped upon this kind of alarms; While the “Maximum-Limit”and “Minimum-Limit”are for severe alarms, and the machine will be stopped immediately with warnings under such circumstances.
Fault Diagnosis Function: Problems like electrical circuit fault, bearing damage, hammer fracture, liner wearing, iron-pass, overload, belt slip, fault of hydraulic and lubrication system, abnormal warehouse inventory, abnormal material level for the bins, etc., can all be discovered by the system and warnings can be released in time for a timely maintenance and repair, so that the breakdown times and time can both be highly reduced in a result.
Remote Communication Function: Via the embedded module device that developed by Unitoon Technology, all the data collected in the field can be uploaded to the cloud service platform in real time, which is the precondition for remote monitoring of the equipment status and production activity.
