Abstract
The utility model provides an auxiliary experimental teaching aid for teaching ''Principles of Open-Loop Control System'' in a module of ''Technology & Design II''. In figure 1, a front (2) of a model is made of transparent materials. When a time-delay circuit (3) is not in use and a switch (5) is pressed, an automatic door is opened and a power on/off indicator lamp (4) is on simultaneously and the power on/off indicator lamp (4) is off after the door is opened. The automatic door is closed after the switch (5) is pressed again, the power on/off indicator lamp (4) is on simultaneously, and the power on/off indictor lamp (4) is off after the door is closed. When the time-delay circuit (3) is in use and the switch (5) is pressed, the automatic door is opened and then is closed automatically and the power on/off indicator lamp (4) is on simultaneously and the power on/off indicator lamp (4) is off after the door is closed. Thus, the demonstration purpose is achieved.
Description
Affiliated technical field:
The utility model relates to the special-purpose teaching aid of a kind of regular senior secondary school current techique course.
Background technology:
At present, because the current techique course is senior middle school's compulsory course that China newly opens, also there is not to be used for satisfying the machinery control teaching aid that teaching is used about the test of open loop control principle.
Summary of the invention:
This utility model provides a kind of and makes things convenient in current techique course " technology and the design II " module, about the ancillary test teaching aid of the teaching of research " open-loop control system principle ".On original automatically-controlled door model, electronic control system changed into and use the control of four blade changed course relay, change the face material of automatically-controlled door model into transparent material, increase its intuitive with this.Demonstrate the principle of work of open-loop control system with this.
The technical scheme that its technical matters that solves the utility model adopts is:
A kind of automatically-controlled door model, this model comprise the transparent panel in model front and delay circuit fixed thereon, and four blade changed course relay, power on/off pilot lamp are fixed on the model side, and two-way switch is fixed on the model end face.
The beneficial effects of the utility model are: this teaching aid is in teaching process, and the student can probe into test easily and fast, and is simple in structure, easy to operate.
Description of drawings:
Fig. 1 is a schematic diagram of the present utility model.
1 is four blade changed course relay among Fig. 1, the 2nd, and model front transparent panel, the 3rd, delay circuit, the 4th, power on/off pilot lamp, the 5th, two-way switch.
Embodiment:
Below in conjunction with drawings and Examples the utility model is further specified.
In Fig. 1, the automatically-controlled door model comprises the transparent panel 2 in model front and delay circuit 3 fixed thereon, and four blade changed course relay 1, power on/off pilot lamp 4 are fixed on the model side, and two-way switch 5 is fixed on the model end face.When not using delay circuit 3, when pressing switch 5, automatically-controlled door is opened, and power on/off pilot lamp 4 is lighted simultaneously, and door is opened back power on/off pilot lamp 4 and extinguished.Automatically-controlled door is closed during at this moment again by a switch 5, and power on/off pilot lamp 4 is lighted simultaneously, and door is closed back power on/off pilot lamp 4 and extinguished.When using delay circuit 3, when pressing switch 5, after opening, automatically-controlled door closes automatically, and power on/off pilot lamp 4 is lighted simultaneously, and door is closed back power on/off pilot lamp 4 and is extinguished, and reaches the purpose of demonstration.
Claims (1)
1. automatically-controlled door model, it is characterized in that: this model comprises the transparent panel (2) in model front and delay circuit (3) fixed thereon, four blade changed course relay (1), power on/off pilot lamp (4) are fixed on the model side, and two-way switch (5) is fixed on the model end face.
