Description

Description and application of the electronically

controlled lecture desk The lecture desk provides with all Facilities a central control system around the process and implementation to be able to optimally organize a lecture.

The desk is shown in Figure 1 on a scale of 1: 4.

With the development of the lecture desk, three goals are achieved: 1. The substitute for blackboard and chalk.

2. Increasing the educational value of a lecture through increasing the number of previous processing levels (memory function) from until he two to -Fiinf.

To relieve the lecturer. Improved lotivation for training.

Re1: When the lecture is called up, all previous secondary activities no longer apply including writing often complicated, time-consuming reaction equations etc.

The available lecture time can be economically timed can be used more cheaply.

: The previous processing levels have so far been essentially limited to the auditory and visual.

The gain in lecture time means that it is repeated again of the lecture, which increases the number of previous processing levels increased from two to four. In addition, there is the processing level of spatial thinking. As, for example, the course of chemical reactions to the spatial imagination is bound, the representation is in a three-dimensional image for a better Understanding is essential.

Re3: The lecturer receives the omission of the writing and the Sideline activities take considerable relief. A better focus on what is to be presented Text is possible. An improved motivation for training is to be expected. Finally the lecturer no longer breathes in the dust of the chalk.

Description of the fields of the lecture desk: 1. Start field, switch on of the Gesaltanlage by means of the switch lock 2.Switch on the television monitor (10 x 4 head) 3. Room acoustics control panel 4. Display of lighting conditions through lamps 5. Adjustment of the desk height according to the body size 6. Control panel for lighting and dimming 7. itikrofone 8. normal time clock and lecture time clock 9. alfa-numeric Display, shows code of the lecture, lecture sequence and picture number.

10. Alarm field, emergency switch for electricity, gas, fire, etc.

11. Control of the large monitor.

12. Deletion device of the code pad 13. Control panel for further required Investments.

14. "" "" "15." "" "" 16. Image selection forwards, backwards, automatically, repeat.

17. Filing of the lecture manuscript.

18.Lighting 19. Code pad, digits 0 to 9.

Function of the lecture desk: 1. Switching on at the field 1. After switching on The monitor prompts you to enter the code.

2. Enter the lecture code and the lecture number on the field 19, the corresponding lecture appears on the monitor, in field 9 the corresponding Number shown.

3. Select the appropriate picture with field 16.

4. All other functions can be accessed using the other control panels can be set according to the requirements.

5. Switch off at field 1 of the device.

Description of Figure 2: 1. Electronically controlled lecture desk (Figure 1) sends data and code to central computer 2. central computer 3. program creation, Data entry, monitoring 4. Data storage 5. Lecture hall 6. Lecture hall 7 ektor 8. Other systems, acoustics, lighting, alarm equipment, etc.

Option: Control by means of a central computer and central memory Function: The central computer manages the memory in which the required data are stored. By entering the appropriate code and the lecture number The correct data is displayed on the large-screen projector at one of the consoles and at the same time at the desk. By pressing the buttons on the control panel 16, the Process controlled.

The data is entered centrally, as is function monitoring of the calculator.

The decisive disadvantages of this concept are: extensive maintenance work, Large memory requirements, staff required, computer failure blocked all Lecture operations, high acquisition costs (computer, memory, cabling, room and staffing requirements).

Advantages: Every lecture is always available.

Description of Figure 3: 1. Electronically controlled lecture desk (figure) 2nd microprocessor with corresponding peripherals.

3. Storage e.g. cassette, floppy disk, etc.

4. Storage and transmission medium e.g. B. Cassette 5. Programming 6. Centrally available program creation 7. Large screen projector 8. Other systems, such as acoustics, lighting, alarms, etc.

9. Archive 2. Possible: Control by means of a microprocessor - each Unit individually - available in every lecture hall.

Function: Each unit is "intelligent", ie. has a microprocessor system, the necessary control commands on the one hand from the lecturer via the corresponding Control panels of the desk (16.19) and of the storage medium, which is initially in a reader inserted (cassette, floppy, disk, etc. received). The lectures are in one Archive stored and transferred to the storage medium with a programming device. At the beginning the appropriate cassette is inserted.

This achieves the greatest possible flexibility, as each system is independent works and lectures can be changed without interfering with an overall system. There is also no need for time-consuming cable processing or monitoring of a Central computer and memory.

Archiving in cassettes is cheaper than in central storage.

A combination of 1st and 2nd is possible for large systems.
