Specific embodiment
A specific embodiment of the invention is made further detailed below against attached drawing by the description to optimum embodiment
Thin explanation.
Production line overhauls defense controls system, the PLC controller including production equipment, for controlling production equipment and adopting
The various state parameters for collecting production equipment further include master controller, maintenance signal acquisition Transmission system, maintenance signal acquisition transmission
System is transferred in master controller for will overhaul signal, master controller according to the presence or absence of maintenance signal judge at this time whether needs
Arrestment, if there is arrestment operation, master controller issues equipment start-stop control signal into PLC controller, PLC controller
According to the start and stop work of the start-up and shut-down control signal control production equipment received, automatically stopped by acquisition inspecting state signal
Only equipment is run, and can be effectively reduced and be thought that operation bring can not the property estimated and the error for avoiding manual operation from occurring.
In a preferred embodiment, maintenance signal acquiring system includes personnel's card swiping device, computer server, people
The identity card of member's card swiping device service personnel for identification, and given by the identity information that ethernet communication mode will test
Enter into computer server, inspection is judged whether it is according to service personnel's information in preset server by computer server
Signal is repaired, if so, issuing enable signal to master controller, master controller issues stopping control signal extremely after receiving the signal
In PLC controller, PLC controller is out of service according to control signal control equipment.By existing between PLC controller and equipment
Field control cable connection.
Programmable logic controller (PLC) PLC be control core, PLC setting with low-voltage distribution room in, PLC controller and master control
It is connected between device processed using the Ethernet of high transfer rate, ensure that the smooth communication of input and output between controller and PLC.Knot
The electrical equipment applicable cases of alloying pipe workshop, it is contemplated that spare part needed for producing and network communication situation, logic control list
Member selects SIEMENS PLC S7-300 series.
Field Force's card swiping device connects computer system server, the confirmation maintenance of computer server by Ethernet
Personnel still maintenance when, computer server by after judging identity information for maintenance personal after background process by signal issue to
Master controller, master controller issue signal to the logic control system of production equipment (PLC), using being distributed long-range control
Device communication realizes data transmission by control cable, and the signal that equipment will be forbidden to run is transferred to PLC, is executed automatically by PLC
Order.
PLC controller is connect by Ethernet with host computer.Host computer acquires PLC internal signal, according to each of setting
The corresponding program of kind of situation, executes fully automatic operation, these programs are according to presetting.The operating condition of every equipment can be upper
It is set in the WINCC picture of position machine.Host computer shows the data information that PLC controller uploads by WINCC picture.
WINCC monitored picture further include: the starting of flowing water built-in unit, operation, halted state are shown.PLC controller and device senses
Device connection, device sensor are used for the running state parameter of detection device.The data that PLC controller uploads include inside PLC
Status data and the various external datas that are detected by sensor, sensor selects to use according to the actual situation.
PLC judges whether system components are in normal operating conditions by collecting the data of each working state of system.
When detecting production equipment failure, PLC will be carried out according to the failure that detects and current working condition corresponding protection and
Warning note, fault cues are in the fault diagnosis picture of man-machine interface.
Remote control signal can also be sent to PLC, and PLC transfers instruction repertorie and give executing agency after receiving instruction,
PLC controls lower production equipment and starts starting operation, if monitoring production equipment still in inspecting state by computer server
Constantly, production run equipment can not start operation, and PLC controller forbids equipment to work, and have inspection on the cast tube assembly line at this time
Personnel are repaired to overhaul；Service personnel confirms that maintenance finishes when all going well, and swiping the card again can be just to host computer signal after determining
Normal starting device operation, resumes production.
