The network control system of injection machine equipment
Technical field
The utility model relates to a kind of control technology of injection machine equipment, particularly a kind of network control system of injection machine equipment.
Background technology
The injection machine apparatus control system of present industrial application is used two kinds of controllers: based on the specific PLC controller with based on the PLC controller of PC, the same characteristic features of two kinds of controllers is that every equipment must possess independently IO interface (the various states of the real-time collecting device operation of input/output port: comprise temperature, position, pressure, switch or the like, and calculate back output control signal corresponding to corresponding relays, solenoid valve or motor etc.), and every equipment must dispose independently central processing system (CPU, RAM, ROM or the like) and man-machine interface.There are several significant disadvantages in this: one, every injection machine all needs to dispose independently IO interface, PLC controller, human-computer interaction interface, causes complex structure, and hardware cost increases, and floor area increases simultaneously; Two, when many injection machines are worked simultaneously, need a plurality of technician to operate, cause the business wage cost up, can't unify operation at a personal-machine interactive interface place by a technician at the human-computer interaction interface place, control inconvenience, need more human resources; Three, owing to human-computer interface system in the injection machine operational process is in dormant state substantially,, cause the waste of tangible resource so hardware resource can not utilize efficiently
The utility model content
The purpose of this utility model is to overcome the deficiency that prior art exists, and provides a kind of simple in structure, controls conveniently, cost is low, the network control system of the injection machine equipment that operational efficiency is high.
The purpose of this utility model is achieved through the following technical solutions: a kind of network control system of injection machine equipment, comprise a human-computer interaction interface, controller, a plurality of IO interface, described human-computer interaction interface is connected with controller, described controller is connected with a plurality of IO interface by network simultaneously, and each IO interface is connected with an injection machine respectively.
Described controller is based on Industrial PC.
Described IO interface is the distributed I/O interface.
Described network is an Industrial Ethernet; Described Industrial Ethernet specifically can be by gigabit bidirectional linked list bus and connects.
The interface of described Industrial Ethernet can be connected with each distributed I/O interface by switch.
Described IO interface is connected with control port on each injection machine equipment.
The utility model has following advantage with respect to prior art:
(1) simple and reasonable for structure; The network control system of this injection machine equipment utilizes one to be connected to network based on Industrial PC as controller and by a human-computer interaction interface, can realize controlling simultaneously the effect of many injection machine work, total system is with respect to the version of an existing machine one control, its assembly reduces, structure is greatly simplified, integrated level is higher, thereby the reduction of relevant hardware cost, and economic benefit is obvious.
(2) control conveniently; Native system can be realized centralized control, utilizing controller can control the duty of many injection machines easily, operates easier; Simultaneously can reduce the Control work personnel, save human resources with respect to prior art.
(3) controller of native system is to design based on Industrial PC, speed of development based on the processor of PC is very rapid, therefore utilize and to realize high speed multitasking ability, can realize high-precision injection machine control simultaneously in the raising computing velocity based on the technical grade controller of PC; Software and hardware can be upgraded easily simultaneously, so this control system can keep higher execution efficient, the required cost of system update is lower.
