Abstract
The utility model discloses a PLC (programmable logic controller) control system of a reach stacker. The PLC control system comprises a PLC master station and a plurality of distributed IO (input/output) modules connected with the PLC master station, wherein each distributed IO module is connected with the PLC master station through a CAN (controller area network) bus and can carry out signal transmission. The PLC control system provided by the utility model has the advantages that wiring harnesses disperse on the distributed IO modules, and wiring harnesses entering a control cabinet are obviously reduced, so that the wiring is structured, and the maintenance is convenient; and in addition, cables are saved, and the speed and the stability of the system are greatly improved.
Description
Technical field
The utility model relates to a kind of PLC control system, and the PLC control system is hung in particularly a kind of front.
Background technology
Present homemade front is hung the PLC control system and is generally adopted central controlled mode.Because execution is hung in the front and detecting element is many, causes system handles efficient not high, wire harness is too concentrated, is difficult to wiring.Bring very big inconvenience for like this operation and maintenance of equipment.
The utility model content
The purpose of this utility model provides the high front of a kind of stability and hangs the PLC control system.
The PLC control system is hung in this front that the utility model provides, comprise PLC main website and some distributed I/O modules that is attached thereto, described distributed I/O module comprises vehicle frame head IO module, vehicle frame afterbody IO module and operator's compartment IO module, vehicle frame head IO module links to each other with the PLC main website by the CAN bus, is used for the acquisition of signal and the control of change speed gear box, hydraulic pressure main valve, pitching valve piece and head car light; Vehicle frame afterbody IO module links to each other with the PLC main website by the CAN bus, is used for the acquisition of signal and the control of jib valve piece, length angular transducer and afterbody car light; Operator's compartment IO module links to each other with the PLC main website by the CAN bus, is used for the acquisition of signal and the data exchange of direction machine, control chair and telltale.
Wire harness of the present utility model is distributed on the distributed I/O module, and the wire harness of control of access cabinet obviously reduces, and it is regular, easy to maintenance to connect up.In addition, the utility model has greatly improved the speed of system when saving cable, significantly improved the stability of system.
Description of drawings
Fig. 1 is a functional block diagram of the present utility model.
Fig. 2 is a kind of specific embodiment layout of the present utility model.
The specific embodiment
As shown in Figure 1, the utility model adopts the mode of a main website and some distributed I/O modules to realize that the front hangs the optimization of PLC control system.The utility model comprises PLC main website, three distributed I/O modules, suspender controller and telltales, and adopts CAN total wire joint main website and each distributed I/O module, carries out data exchange.
The PLC main website comprises the vehicle frame controller, and this controller is placed in the vehicle frame control housing, is used for collection, analyzing and testing signal and the action of control car load.
The distributed I/O module comprises vehicle frame head IO module, vehicle frame afterbody IO module and operator's compartment IO module.Vehicle frame head IO module links to each other with the PLC main website by the CAN bus, is used for the acquisition of signal and the control of change speed gear box, hydraulic pressure main valve, pitching valve piece and head car light; Vehicle frame afterbody IO module links to each other with the PLC main website by the CAN bus, is used for the acquisition of signal and the control of jib valve piece, length angular transducer and afterbody car light; Operator's compartment IO module links to each other with the PLC main website by the CAN bus, is used for the acquisition of signal and the data exchange of direction machine, control chair and telltale.This distributed I/O module is an outsourcing piece, because it is arranged on the outer vehicle frame of control housing, can select the high IO module of degree of protection and antidetonation grade for use.
As shown in Figure 2, the front hung be divided into five parts, vehicle frame head, vehicle frame afterbody, vehicle frame middle part, driver's cab and suspender are arranged master controller, the other parts distributed I/O on vehicle frame middle part and suspender.Suspender controller 1 is installed on the suspender, and operator's compartment IO module 2 is installed in the operator's compartment, and vehicle frame afterbody IO module 3 is installed in the vehicle frame afterbody, and vehicle frame controller 4 is installed in the vehicle frame control housing, and vehicle frame head IO module 5 is installed in the vehicle frame head.
Claims (1)
