Technical field:
The utility model relates to supporting experiment (instruction) equipment technical field of teaching, refers in particular to the model actual training device that a kind of student of confession practises programming and can obtain the practical operation sight.
Background technology:
Known, teaching can make the student deepen institute and gain knowledge in conjunction with real training, improves manipulative ability.For study programming (as the programming of PLC programming, DDC controller), real training is then even more important.At present, the actual training device that is used to programme is limited, as be used to feed water and the programming exercise apparatus of the programmed control of unwatering system then lacks, and can not allow the student directly carry out operation practice with the feedwater and the unwatering system of actual field, thereby also just influence the grasp of student to being gained knowledge.
The utility model content:
The purpose of this utility model is to provide a kind of student of convenience the exercise of programming, and can obtain the real simulation of control procedure, strengthens the supply and drain water system model actual training device of training entertaining.
For achieving the above object, the utility model adopts following technical scheme:
Supply and drain water system model actual training device, this device comprises a support, feed-tank, discharge casing, make-up pump, unwatering pump are installed on support and join a control box, the field control system of DDC controller, power supply and relay is housed in the control box, input/output control signal all is coupled on the terminals of field controller, by to downloading to controller behind the DDC controller programming, realize feedwater and pumping monitoring and control; The feed-tank liquid level sensor is housed in the feed-tank, and the discharge casing liquid level sensor is housed in the discharge casing.
Above-mentioned support bottom has roller.
This device is provided with manual control and automatic control mode.
The supply and drain water system model actual training device that the utility model provides, it is simple in structure, and volume is small and exquisite, makes things convenient for student's exercise of programming, and can obtain the true dynamic similation of control procedure, reaches the theory and combining actual teaching, excites the enjoyment of student's learning controller programming.
Description of drawings:
Accompanying drawing 1 is a structural representation of the present utility model;
Accompanying drawing 2 is the electrical panel figure of the utility model one embodiment.
Embodiment:
Understand for the juror can be had purpose, feature and the function of the utility model further, lift preferred embodiment now and cooperate graphic being described in detail as follows:
See also shown in Figure 1, it is the structural representation of the preferred embodiment of the utility model, the utility model is relevant a kind of supply and drain water system model actual training device, this device comprises a support 10, feed-tank 51 is installed on support 10, discharge casing 52, make-up pump 53, unwatering pump 54 and join a control box 20, DDC controller 21 is housed in the control box 20, the field control system of power supply and relay, input/output control signal all is coupled on the terminals of field controller, by to downloading to controller behind the DDC controller programming, realize monitoring and control to feedwater and draining; The feed-tank liquid level sensor is housed in the feed-tank, and the discharge casing liquid level sensor is housed in the discharge casing.
Support 10 bottoms have roller 11, are convenient to move and the real training operation.Device is provided with manually and automatic mode, satisfies the real training requirement, allows the more understanding knowledge of student.Support 10 is an inverted T-shaped, and control box 20 is installed in side before the erect plate, and feed-tank 51, discharge casing 52, make-up pump 53 and unwatering pump 54 etc. are installed in side after the erect plate.
Embodiment:
Consult shown in Figure 2ly, the supply and drain water system model equipment possesses two kinds of functions of feedwater demonstration and draining demonstration, is selected by a button; Device also is furnished with a total air switch controlling models and powers on, and has the power light indication; DDC controller 21 is installed on the front panel.
When front panel button was selected the feedwater demo mode, system promptly possessed to water function.Two feed pumps all have the automatic/hand mode of operation and select; During automatic mode, the startup of feed pump stops to control (by the feed-tank level sensor monitors) by DDC controller 21 according to the water level situation, when the elevated tank water level arrives low-water level, starts feed pump, when the elevated tank water level is higher than high water stage, stop feed pump.In like manner, when front panel button was selected the draining demo mode, system promptly possessed drain function.Two unwatering pumps all have the automatic/hand mode of operation and select; During automatic mode, the startup of unwatering pump stops to control (by the discharge casing level sensor monitors) by DDC controller 21 according to the water level situation, when the low flush tank water level arrives low-water level, stops unwatering pump, when the low flush tank water level is higher than high water stage, start unwatering pump.During manual mode, corresponding feed pump or unwatering pump are not subjected to 21 controls of DDC controller, are started/are stopped by the startup on the control panel/stop button control.Two water pump the using and the reserved, when a water pump fault, No. two water pumps of automated system operation.
The native system core controller is selected Excel 50 controllers of Honeywell company for use, and the Excel50 controller itself has the input of 4 way switch amounts, the output of 6 way switch amounts, the input of 8 tunnel analog quantitys, the output of 4 tunnel analog quantitys.
The switching value that system detects comprise two give (row) water pump mode of operation, running status and fault alarm etc. are set, the analog quantity of system's detection is the water level of feed-tank.
System can adopt two kinds of control models to comprise automatic mode and manual mode.During automatic control mode, all devices starts/stops the control by DDC, and controlled condition is judged system's operation with closed ring according to the relevant environment condition that DDC gathers.Manually during control model, the startup of every equipment/stop to control separately by electrical control startup, stop button cashier's office in a shop, equipment has nothing to do with the control of DDC controller, and automatic mode need be worked out the DDC control program.
The utility model mainly provides a kind of actual training device, remedy the existing defective that lacks similar device with this, to satisfy the requirement of practice teaching, promote teaching, carry out DDC controller experiment (instruction) teaching applicable to ordinary higher learning school, professional colleges and all kinds of skills trainings center, the DDC controller that is fit to various brands carries out the programming Control training of various simulation real processes; This model also can be used as in the building automatic teaching demonstration system one by control subsystem.
