Technical field
The present invention relates to the control technology of belt conveyer, specifically a kind of intelligence controlling device of the belt conveyer based on PLC.
Background technology
Belt conveyer has become the main transportation device of raw coal transportation system under the coal mine because it has that long distance is carried continuously, operational throughput is large, reliable, efficient is high, is easy to the advantage such as automation.At present, along with developing rapidly of high-yield and high-efficiency mine, no matter existing belt conveyer is the requirement that principal parameter or drive ability all can not satisfy high-yield and high-efficiency, thereby it must be to maximization, long distance, high belt speed, large conveying quantity, high-power, intelligent direction development.In order to realize belt conveyer to above-mentioned future development, need to carry out Based Intelligent Control to the various piece of belt conveyer.Be necessary to invent a kind of device that specially belt conveyer is carried out Based Intelligent Control for this reason.Yet there is no at present a kind of like this device.
Summary of the invention
The present invention there is no a kind of problem of specially belt conveyer being carried out the device of Based Intelligent Control at present in order to solve, and a kind of intelligence controlling device of the belt conveyer based on PLC is provided.
The present invention adopts following technical scheme to realize: the intelligence controlling device based on the belt conveyer of PLC comprises main control part and controlled part; Described main control part comprises PLC controller, HMI equipment, industrial computer, PROFIBUS-DP bus and MPI(Multi Point Interface, multipoint interface) network; Described controlled part comprises frequency converter, belt conveyer power distribution protection circuit, belt conveyer general protective circuit, belt conveying owner's motor, belt conveyer front and back equipment running control circuit, belt conveyer brake control circuit, belt of belt conveyor tensioning control circuit, belt conveyer belt conveyer scale control circuit and Reducer in Belt Conveyor control circuit; Wherein, the mouth of HMI equipment is connected with the input end of PLC controller by the PROFIBUS-DP bus; The mouth of industrial computer is connected with the input end of PLC controller by the MPI network; The input end of the input end of frequency converter, belt conveyer power distribution protection circuit, the input end of belt conveyer general protective circuit all are connected by the mouth of PROFIBUS-DP bus with the PLC controller; The input end of equipment running control circuit, the input end of belt conveyer brake control circuit, the input end of belt of belt conveyor tensioning control circuit, the input end of belt conveyer belt conveyer scale control circuit, the input end of Reducer in Belt Conveyor control circuit all are connected by the mouth of MPI network with the PLC controller before and after the input end of belt conveying owner's motor, the belt conveyer.
During work, equipment running control circuit, belt conveyer brake control circuit, belt of belt conveyor tensioning control circuit, belt conveyer belt conveyer scale control circuit, Reducer in Belt Conveyor control circuit all are installed on the belt conveyer before and after frequency converter, belt conveyer power distribution protection circuit, belt conveyer general protective circuit, belt conveying owner's motor, the belt conveyer.The specific works process is as follows: the user programmes by industrial computer, and industrial computer is inputted programming instruction by the MPI network to the PLC controller.The user is by the HMI operate, and HMI equipment passes through the PROFIBUS-DP bus to PLC controller input operation instruction.The PLC controller carries out Based Intelligent Control to frequency converter, belt conveyer power distribution protection circuit, belt conveyer general protective circuit according to programming instruction and operating order respectively by the PROFIBUS-DP bus.The PLC controller carries out Based Intelligent Control to equipment running control circuit, belt conveyer brake control circuit, belt of belt conveyor tensioning control circuit, belt conveyer belt conveyer scale control circuit, Reducer in Belt Conveyor control circuit before and after belt conveying owner motor, the belt conveyer according to programming instruction and user's operation respectively by the MPI network.Based on said process, the intelligence controlling device of the belt conveyer based on PLC of the present invention is by adopting brand new, realized the various piece of belt conveyer is carried out Based Intelligent Control, and then realized that belt conveyer is to maximization, long distance, high belt speed, large conveying quantity, high-power, intelligent direction development.Simultaneously, the intelligence controlling device of the belt conveyer based on PLC of the present invention carries out Based Intelligent Control by the various piece to belt conveyer, has improved the reliability of belt conveyer, and has significantly reduced productive costs.
The present invention efficiently solves and there is no at present a kind of problem of specially belt conveyer being carried out the device of Based Intelligent Control, is applicable to the Based Intelligent Control of belt conveyer.
