Description
Technical field
The present invention relates to a kind of electric control system of Hydraulic Experimental Platform, suitable for machinery field.
Background technology
The important content of electromechanical integration includes hydraulic transmission technology, and Hydraulic Experimental Platform be then in order to study, produce and
Develop Hydraulic Elements and the important experimental facilities of hydraulic system.It is formed in the Hydraulic Experimental Platform equipment for being engaged in hydraulic test in the past
It immobilizes, and control mode is simply unique, the degree of automation is low, does not possess scalability.With the development of science and technology,
With hydraulic transmission technology study and produce deepen continuously, it is higher and higher to the equipment requirement of Hydraulic Experimental Platform.Therefore, it is badly in need of
Develop a set of high degree of automation, control it is reliable and stable and expansible, there is the electrical control system of mechanical-electrical-hydraulic integration
System.
Hydraulic Experimental Platform include 2 parts of electrical control cabinet and hydraulic running device, electrical control cabinet using to after
Electric appliance carries out remote control, due to the defects of service life of relay is short, control is inaccurate, with hydraulic system research and answers
More deep, the electrical control cabinet realized using relay this at present cannot increasingly meet Hydraulic Experimental Platform
Requirement of experiment.
The content of the invention
The present invention proposes a kind of electric control system of Hydraulic Experimental Platform, is not only able to realize what is be remotely monitored and controlled
Purpose also has the function of audio alert, report output etc., realizes the automation control of Hydraulic Experimental Platform system.
The technical solution adopted in the present invention is：
The control system is made of host computer, computer and slave computer, PLC, by computer to test parameters such as pressure, displacements
Carry out data sampling and processing, display etc..
In the electric control system, the pressure data that pressure sensor measures first passes around AD conversion, is converted into number
Amount is then sent to PLC, and the displacement of hydraulic cylinder after AD conversion similarly by being sent to PLC, while PLC can also be collected
Close to the quantity of state of switch.
Overload alarm function has also been devised in the control system, when some sensor measurement data beyond limitation model
It encloses, system then can export a control signal by PLC, control alarm, remind the faulty generation of staff.
The control system can also monitor the operating status of experimental bench field device and current displacement situation, pressure in real time
Power size and the operating status of oil circuit etc., control system also have simple self diagnostic capability, it is ensured that whole system safely may be used
The operation leaned on.
The beneficial effects of the invention are as follows：The Hydraulic Experimental Platform Control System Design is reasonable, and the selection of hardware is just right, soft
The design of part can also meet the requirements, is workable, is powerful, and the spot sensor data detected are coincide with actual, right
Also accurately and timely, entire Hydraulic Experimental Platform system run all right is reliable, and monitoring effect is fine for the control of motor, relay etc..
Description of the drawings
Fig. 1 is the control system the general frame of the present invention.
Fig. 2 is the PLC control system composition figure of the present invention.
Fig. 3 is the upper computer software composition frame chart of the present invention.
Fig. 4 is the system failure display figure of the present invention.
Specific embodiment
The invention will be further described with reference to the accompanying drawings and examples.
Such as Fig. 1, programmable logic controller (PLC) (PLC) is a kind of electronic system for performing digital operation, main to apply
In industrial production, it using microprocessor as core, combine computer technology, automated control technology and the communication technology in
One, because PLC has small, strong antijamming capability, powerful, program is simple, agile and all-purpose and easy to maintain etc. special
Point, and PLC is caused to become one of controller being most widely used in the control of current industrial automation process.
It is the automatic control system of core fundamentally instead of traditional relay control system using PLC.Traditional
The realization principle of relay control system is that entire control logic is realized by wiring, and the control of PLC control system is patrolled
It collects and all embodies in a program, control principle and control process are described by program language, with reference to the digital quantity or mould of PLC
Analog quantity inputs, so as to change the output quantity of PLC.
Control system is made of host computer, computer and slave computer, PLC.By computer to test parameters such as pressure, displacements
Carry out data sampling and processing, display etc..In experimentation, computer can also according to setting value and the value of feedback of sensor,
Executing agency is controlled, realizes monitoring, tracking and control of the control system to experimental bench.
Such as Fig. 2, the pressure data that pressure sensor measures first passes around AD conversion, is converted into digital quantity and is then sent to
PLC；The displacement of hydraulic cylinder after AD conversion similarly by being sent to PLC；PLC can also collect the shape close to switch simultaneously
State amount.PLC can export controlled quentity controlled variable, since the controlled quentity controlled variable of PLC outputs is digital quantity, so needing first to carry out DA conversions, then
Remove control solenoid directional control valve.
Such as Fig. 3, using development platform of the Configuration software WinCC as upper computer software, upper computer software is mainly used to reality
Existing human-computer dialogue.Upper computer software mainly includes following content.
1. button part：Upper computer software has some buttons, for being operated to executing agency, the start and stop including water pump
Deng；2. overview part：There is entire experimental bench system in overview part a introduction and description substantially, understands convenient for staff；
3. the interface of interface portion upper computer software includes subscriber administration interface, monitoring interface, alert interface, trend interface, filing circle
The contents such as face and report printing interface.Subscriber administration interface help user to input/output port be configured management and it is right
Relevant parameter is configured；Monitoring interface includes vision signal of some experimental benches etc.；Trend interface is used to show sensor
Continuous output understands the dynamic changing process of parameter convenient for staff.
Such as Fig. 4, overload alarm function has also been devised in system, when some sensor measurement data beyond limitation model
It encloses, system can then export a control signal by PLC, and control alarm (being herein buzzer warning) reminds staff
Faulty generation.System can also monitor in real time experimental bench field device operating status and current displacement situation, pressure it is big
Small and oil circuit operating status etc..Control system also has simple self diagnostic capability, it is ensured that whole system is safe and reliable
Operation.
