Installment and Use

Which is better, electronic whiteboard or teaching all-in-one machine/smart blackboard?

Traditional interactive electronic whiteboard:

1. Ordinary electronic whiteboards need to be used in conjunction with projectors, as the projected images are not clear and the projector bulbs become dim due to prolonged use, resulting in a limited lifespan.

2. Projection requires a darkroom environment, where students can see the projected content clearly but cannot see the teacher's expression clearly.

3. Need to connect different devices such as PCs, projectors, and various cables that are messy and disorderly.

4. Students have difficulty concentrating and their classroom efficiency needs to be improved.

5. The front projection light is glaring, causing damage to the teacher's eyes and casting shadows on the screen.

Multimedia teaching all-in-one machine:

1. One piece and high integration, integrating OPSPC computer, projection system, screen, display system, audio, and multi touch into one.

2. Not affected by external light sources

3. High definition display screen, clear image, no problem of dazzling front projection light

4. Easy installation, built-in computer

5. Equipped with HDMI high-definition multimedia and other interfaces

The difference between electronic whiteboard and multimedia teaching all-in-one machine:

1. Different levels of convenience in use

The touch all-in-one machine integrates electronic whiteboard software, computer, TV, host, monitor, and audio into one, eliminating tedious wiring and only requiring one power cord connection. Nowadays, all touch all-in-one machines support WIFI function and eliminate the trouble of plugging in network cables. However, electronic whiteboards need to be connected to projectors, computers, audio systems, etc., with complex wiring and cumbersome use.

2. Different clarity

The image clarity of the teaching all-in-one machine is 4-5 times that of the projector, and even in sunlight, clear images can be enjoyed, ending the "dark age" of curtain teaching; The screen has undergone special treatment to resist scratches, corrosion, easy cleaning, and impact, and has anti reflection and scattering technology; The display is not affected by light, infrared, etc., and there is no shadow on the screen when writing.

3. Different levels of health and safety

Touch all-in-one machine is healthy, environmentally friendly, safe and reliable: zero radiation, low power consumption, no noise, which is conducive to protecting eye and body health; The TV display method avoids eye damage caused by direct sunlight from the projector when the teacher is teaching in front, and protects both the teacher and students from chalk dust.

4. Different maintenance costs

The touch all-in-one machine is easy to operate and has a long service life, with a super low operating cost compared to electronic whiteboards. The projectors used in traditional electronic whiteboards vary in quality, and after a period of use, the projector or rear projection light bulb needs to be replaced, with a cost of about 2000 to 6000 yuan per replacement, which increases the cost of using the electronic whiteboard in the later stage. And the lifespan of the touch all-in-one machine is as long as 50000 hours, with almost no other usage costs.

How to use the multimedia teaching all-in-one machine/smart blackboard used in the classroom:

Instructions for using multimedia teaching all-in-one machine (operating steps)

Step 1: The class administrator uses the key to open the blackboard.

Step 2: Press the power button on the lower right panel of the teaching all-in-one machine to synchronize the computer projection and power on.

Step 3: Carry out normal teaching work.

Step 4: Shutdown after class: Press the power button on the lower right panel of the teaching all-in-one machine, and the computer projector will shut down synchronously. Or shut down the computer through the shutdown program of the computer system. After turning off the computer, the projector will automatically shut down after sufficient cooling.

Step 5: The teacher closes the blackboard: After moving it to a certain position, pop out the bottom of the blackboard and press the lock upwards, then lock it with the key.

Other functions and usage methods of the teaching all-in-one machine

1. Play music or videos directly from the USB drive

Operation process: Connect the USB flash drive directly to the external USB interface on the right side of the all-in-one machine, set the signal source selection to "Multimedia", and use the all-in-one machine panel buttons to play sound or video.

2. Using a laptop with a projector as the output device

Operation process: Connect the laptop to the VGA input interface on the right side of the projector using a VGA cable, and then adjust the corresponding input source.

3. Using teaching all-in-one machines to carry out class entertainment activities

You can use the video playback function of this device to carry out entertainment activities. Instructions: Install the "Cool Me K Song" software and use it to download songs prepared for performance from the internet in advance; Connect an external microphone to the audio input jack of the computer (there is a 6.5 plug on the right side of the all-in-one machine), this method can only use one microphone. If you need to use two microphones, you need to install an additional amplifier device, connect the microphone to the amplifier, and then connect the output of the amplifier to the computer audio input line.

Possible problems and solutions during the use of teaching all-in-one machines

1. During the use of the computer, there may be malfunctions such as blue screens or crashes

Solution: There is a main power switch on the right rear of the teaching all-in-one machine. Find that switch, turn off the main power, turn it back on after 20 seconds, and then turn it on again using normal methods.

2. During the use of the computer, there may be inaccurate positioning of the touch screen

Solution: Use tissue paper to wipe off the dust on the inside of the frame around the all-in-one machine screen, especially the chalk dust below.

Precautions for using multimedia teaching all-in-one machine (very important):

1. Illegal shutdown is prohibited during use

2. Prohibit modifying pre-set setting parameters

3. Continuous use generally does not exceed 4 hours, and the summer time with high temperatures should be even shorter

4. It is recommended to open the class in the morning and close it at noon when frequently used, and then open it again in the afternoon and close it at the end of the class (if not used in the next class, do not open it)

Precautions for screen use:

1. Prohibit the use of sharp objects to depict or strike surfaces

2. Prohibit writing with pens other than electronic pens (such as brushes, water-based pens, etc.), and use electronic pens for writing

3. Stay away from water sources, juices, chemicals, and other water-based products

4. If you need to clean the board surface, you can first wipe it with a non dripping wet cotton cloth, and then dry it with a dry cotton cloth

5. When not using the electronic pen for a long time, the battery should be removed to avoid wasting battery power

Audio usage suggestions:

Adjust the audio volume to 2/3 of the total volume and control it through the computer (with slight modifications to the size of the audio volume field of view)

Maintenance knowledge of multimedia teaching all-in-one machine:

1. In the use of multimedia teaching all-in-one machines, the phenomenon of scratching the surface of products due to collisions between products should be avoided

2. The touch screen of the multimedia teaching all-in-one machine should not be excessively shaken in daily use, as severe shaking may cause damage to the screen.

3. It is best not to place objects on the touch screen, otherwise the pressure on the screen may be too high, which may result in slow response or insensitive touch.

4. The touch screen should be kept clean. If there is dust or dirt on the surface, it should be cleaned. When wiping, please turn off the power of the multimedia teaching all-in-one machine.

5. When cleaning the surface of the multimedia teaching all-in-one machine, use a soft cloth dipped in some petroleum ether to wipe it. Attention: During this process, do not use corrosive organic solvents such as industrial alcohol to wipe the surface of the touch screen film.

6. In the use of multimedia teaching all-in-one machines, we should pay attention to the issue of turning them on and off.
