For the deficiencies in the prior art, the purpose of this utility model is to provide one can realize efficient step control, the reactor automatic charging control system of reliable communicating between control system and between control system and production equipment, comprise PLC central controller, described reactor automatic charging control system also comprises operation site host computer, control center's host computer, frequency converter controller, weighing instrument, remote site, PLC central controller and operation site host computer, control center's host computer, frequency converter controller, weighing instrument, remote site respectively network communication connects.
Further, described PLC central controller is connected by EtherNet network communication with between operation site host computer and control center's host computer.
Further, described PLC central controller is connected by ControlNet network communication with remote site.
Further, described PLC central controller is connected by DeviceNet network communication with between frequency converter controller and weighing instrument.
In sum, the beneficial effects of the utility model are: a kind of reactor automatic charging control system of the present utility model, by the optimal design of system hardware equipment and the improvement of communication mode, to realize between control system and reliable communicating between control system and production equipment, cooperation between operation site, remote site, control center, efficient step control, is suitable for chemical industry reactor automatic charging and uses.
Accompanying drawing explanation
Fig. 1 is the new structure schematic diagram of this practical a kind of reactor automatic charging control system.
In figure, 1, PLC central controller, 2, operation site host computer, 3, control center's host computer, 4, frequency converter controller, 5, weighing instrument, 6, remote site.
Embodiment
Below in conjunction with accompanying drawing and embodiment, the utility model is further described:
As shown in Figure 1, reactor automatic charging control system, comprise PLC central controller 1, also comprise operation site host computer 2, control center's host computer 3, frequency converter controller 4, weighing instrument 5, remote site 6, PLC central controller 1 and operation site host computer 2, control center's host computer 3, frequency converter controller 4, weighing instrument 5, remote site 6 respectively network communication are connected.
Adopt RockwellControlLogix series of PLC as PLC central controller 1, on-the-spot each remote site 6 adopts FlexI/O to be connected with PLC central controller 1 by ControlNet, frequency converter controller 4, weighing instrument 5 all by DeviceNet with the mode of network and PLC central controller 1 communication, PLC central controller 1 is connected by EtherNet network communication with between operation site host computer 2 and control center's host computer 3.The transmission of network can ensure the accurate and stable of data.There is not analog signals and gather unstable situation.
ControlNet network is a kind of high speed deterministic network, for there being the information transmission of the application scenario of rigors to the time.It controls and message transmission service in real time for peer-to-peer communications provides.It tells communication link as between controller and I/O equipment, combines the ability of existing various network.
ControlNet is applicable to system system determinacy and repeatability being had to important requirement, thus ensures reliably, the synchronous and real-time control performance coordinated.The determinacy of system is used for reliably predicting when submit data to and repeatablely ensure that the delivery time constantly not to be networked or from the impact of net equipment.These features are selected the controller update time of I/O and associated from satisfied application needs by user and are further improved.
The equipment of bottom, by the network of an opening, is connected with workshop level controller by DeviceNet network, without the need to by rigid line by them and I/O model calling.Worldwide 150 Duo Jia dealer actively support that open type DeviceNet sellers association (ODVA) is based on the network of CAN technology.
The network of this 64 nodes, branched line, allows user to go the connection of the equipment connected within 500M with a cable, greatly saves the expense of wire, and convenient installation.
DeviceNet is the network schemer based on the producer/consumer, and this is go-go network technology, and this pattern makes control data arrive each unit of operation simultaneously, more effectively can utilize the bandwidth of network.
The producer/consumer's pattern can significantly reduce network communication amount simultaneously, because the message that its enable state switches sends, responds faster to make.Meanwhile, periodic message sends, to provide better determinacy.Peer-to-peer communications permission data and status information again equipment room exchange, and these advantages are as responded faster, and better determinacy, the dirigibility of enhancing, all these can produce higher throughput rate.
Employing cost performance is high, the DeviceNet network that versatility is good.Powerful network function can ensure that system is quick, stable, run efficiently.
Central Control Room arranges two computing machines as control center's host computer 3, and the dynamic menu that operating personnel design by RSViewSE, curve, form conveniently understand field conditions, very clear to the operating mode of whole plant area.Efficiency is improved greatly.
Arrange a PanelViewPlus as operation site host computer 2 at the scene, operating personnel can directly carry out monitoring and operating at the scene.
Each remote site 6 forms distributed site jointly, and adopt the distributed I/OFLEXI/O of Rockwell company, each website is made up of ControlNet network adapter and I/O module.Network adapter connects central control station with by ControlNet, and adapter sends the data of on-the-spot I/O to cpu, and cpu, by being exported to output module by action command after routine processes, completes field control again.
For a person skilled in the art, according to above technical scheme and design, other various corresponding change and distortion can be made, and all these change and distortion all should belong within the protection domain of the utility model claim.
