Abstract
The invention, which belongs to the industrial control system technology field, discloses a spherical graphite production line centralization control system. By using a traditional single distributed spherical graphite production equipment control box, in a production field, on-site conductive graphite particles are easy to damage an electrical part and hurt operation personnel. The system of the invention, which is arranged concentratedly and individually, comprises: a PC machine, an industrial router and a plurality of control cabinets. A plurality of control cabinets form parallel connection. The PC machine is connected with the industrial router through Ethernet. The each control cabinet comprises: a main and an auxiliary small size PLCs, a touch screen and a frequency converter. The main PLC comprises: an analog input and output module and an Ethernet module. The auxiliary PLC comprises: the analog input and output module. The main PLC is connected with the industrial router through the Ethernet. The main PLC is connected with the auxiliary PLC and the frequency converter respectively through an RS485 bus. The main PLC is connected with the touch screen through an RS232 bus. Equipment maintenance difficulty, equipment costs and maintenance costs can be reduced. The device and the operation personnel can be avoided to be damaged and hurt.
Description
Technical field
The invention belongs to the industrial control system technical field, especially relevant with a kind of graphite spheroidization production line control system.
Background technology
The production of graphite spheroidization is that blocky graphite or the bigger dag of granularity are broken into the fine granularity spherical graphite particle about 30 microns.In the graphite spheroidization production scene, have a large amount of motors to need control, according to arts demand, the start and stop of motor have strict requirement in proper order.And the equipment blower fan need be realized the start and stop control of motor through soft initiator, and main frame, classification will be adjusted motor speed in real time according to arts demand, and the aperture of valve needs adjustment at any time.Manual control is all adopted in traditional disintegrating apparatus control, and every comminutor is established a control box separately, and all operations all need the operating personnel scene of being distributed to could realize that process concatenation all needs operating personnel rule of thumb to adjust.Some data in process of production will be leaned on manual record.Contain more conductive particle in the air of graphite ball-type production scene, cause control in-box electric appliance spoilage very high, also can damage the healthy of operator.The concentrated control system that medium-and-large-sized PLC forms, cost is very high, and the PLC program is complicated, and is also very high to field maintemance personnel requirement, is not suitable for the commercial application of graphite spheroidization production equipment.
Summary of the invention
The object of the invention is exactly to overcome that the electrical damage rate in the production scene that the graphite spheroidization production equipment control box of traditional single decentralized exists is high, operating personnel are healthy vulnerable, provides that a kind of cost is cheap relatively, security of operation, graphite spheroidization production line centralized control system easy and simple to handle.
For this reason; The present invention adopts following technical scheme: graphite spheroidization production line centralized control system; It is characterized in that: described centralized control system comprises PC; Industry router and a plurality of switch board; A plurality of switch board parallel connections; Be connected through Ethernet between PC and the industrial router; Each switch board comprises the master; Secondary two small PLCs; Touch-screen and frequency converter; Main PLC comprises analog quantity input/output module and ethernet module; Secondary PLC comprises the analog quantity input/output module; Main PLC is connected with industrial router through Ethernet; Main PLC and secondary PLC; Connect through the RS485 bus respectively between the frequency converter, be connected through the RS232 bus between main PLC and the touch-screen.
When the present invention uses; The quantity of switch board is corresponding with composition graphite spheroidization Production Line amount of equipment; Be connected with data acquisition executing agency by data wire with secondary PLC according to main PLC; By the exchanges data of analog quantity input/output module realization with datagram number collection executing agency; Data acquisition executing agency is according to the strong and weak automatic execution instruction of the signal of telecommunication; The data acquisition system that secondary PLC receives is to main PLC; Main PLC is unified to carry out exchanges data by its ethernet module and PC; Frequency converter is connected with the motor of graphite spheroidization production equipment, and frequency converter is realized the control to electric motor starting according to the instruction that main PLC sends.In graphite spheroidization production scene, establish the pulpit separately, all switch boards all are placed in the pulpit, are connected through cable with field apparatus, have avoided some to produce the field and have contained the conduction problem that dust brought.
As to technique scheme replenish and perfect, the present invention also comprises following additional technical feature.
Described centralized control system also comprises printer, and printer is connected through data line with PC.
Use the present invention can reach following beneficial effect: the function through major and minor two small PLCs combination realization Medium PLC, reduced the plant maintenance difficulty, reduced equipment cost and maintenance cost; Control system is concentrated and is isolated setting with production equipment, avoids system device and operating personnel to receive the graphite particle damage of production scene.
