--- Based on Model KJD5 Programmable Controller |
Model KJ161 Mine-used Monitoring and Control System for Belt Conveyor Based on Model KJD5 Programmable Controller, suitable for coal mine underground and surface severe environment, can be used as single electric-control device for belt conveyor of heavy loading and long distance, and the multiple single systems can be networked as centralized control system for multi-belt. It can be networked with Integrated Mine Wide Automation System. |

|
 |
The system has 4 operating modes of centralized control, automatic control, manual control and program control. |
|
The system has functions of voice announcement for start, dotting liaison and voice communication along belt conveyor line. |
|
The system has functions of multi-point drive, soft start and power balance control. |
|
The system can realize interlocking function between belt conveyors and between belt conveyor and coal feeder, and realize start/stop control in normal sequence. |
|
The system can realize optimized control of coal feeder and coal feeding, and controls of divided mining, divided storage and divided transportation. |
|
The system can realize automatic adjustment of belt tension. |
|
The system has multiple protection devices for stop and locking for emergency, slippage (over-speed), misalignment, longitudinal tearing, coal stacking (blockage), full bunker, overtemping sprinkling, smoke and low limit of tension, realizing automatic stop, location display and sound alarming for fault. |
|
The system has functions of detection and call for display of location of misalignment and emergency stop, belt speed, motor current, motor temperature, roller temperature, belt tension and coal level of bunker. |
|
The system is programmable, and points of input and output of the system are extendable, meeting special requirements of users. |
|
Build a network by self, the system can realize centralized control for multiple belt conveyors. |
|
The system can be networked with monitoring and control system of whole mine or factory. |
