Daily maintenance of interactive whiteboard (new favorite in the classroom)

Beijing hosted the Olympic Games in 2008, Shanghai hosted the World Expo in 2010... These series of major milestones that have occurred or are about to happen have made every Chinese feel that globalization is not a distant fairy tale, but a tangible story. Reality that can be obtained. In order to prevent children from losing at the starting line in the era of globalization, quality education for infants and children has been gradually strengthened in recent years, and teaching methods have been continuously reformed to meet the needs of children's growth. At the same time, in order to stimulate children's curiosity and creativity, interactive smart whiteboards are increasingly being used in preschool education, primary and secondary schools as an auxiliary device for multimedia teaching.

The interactive intelligent electronic whiteboard is combined with the existing multimedia teaching equipment, which does not waste the existing resources of the school, but also can effectively combine the multimedia equipment and devices such as computers, physical exhibition stands, projectors and campus networks to make what is presented in the classroom The content immediately becomes an editable dynamic resource. The finger is the mouse. You can easily write on the electronic whiteboard, draw pictures and control computer programs. You can also search for related subjects online, conduct popular science demonstrations or virtual outdoor excursions, and maximize assistance The role of teaching is to truly realize the modernization of multimedia classroom teaching. Its powerful interactive function has fundamentally changed the traditional way of teaching only by teachers and passively listening by students, providing great convenience for the interaction and participation of teachers and students in the teaching process, and learning has become more fun.

　　 But, as a teacher or parent, have you ever cared about the environmental protection of interactive smart whiteboards? In your daily close contact with interactive smart whiteboards, have you considered that they pose a threat to the health of teachers and children?

At present, the education industry generally adopts front-projection interactive smart whiteboards, which are divided into four camps: resistance pressure sensitivity, electromagnetic induction, infrared matrix and ultrasonic based on the realization principle. From the two standards of environmental protection and ease of use of technology, comprehensive inspection The resistance pressure sensitive interactive smart whiteboard is more popular. This is because the resistive pressure sensitive interactive smart whiteboard uses advanced pressure sensitive technology, without any dust and electromagnetic radiation, and can be touched and slapped with confidence. In this way, there is no choking chalk dust in the classroom, and it will not be like a computer and other equipment. That produces radiation; and its positioning is accurate. Teachers don’t need to change any blackboard writing habits. They can use it freely. They don’t have to bow their heads and be busy operating multimedia devices as before, while struggling to copy exercises on the blackboard. They can teach in a healthier and more comfortable way. The health of teachers and classmates is very good.

　　The resistance pressure sensitive interactive smart whiteboard is a large-size interactive touch system designed for business meetings, industry applications, education, training and other places. Just connect it to your computer and projector, you can use your fingers to write on the projection screen and operate the computer easily. When no object touches the surface of the whiteboard, the two conductive films can have repulsion without pressure. When you tap the writing film on the surface of the whiteboard with your finger, the two conductive films are connected together at the point where you click, and the voltage of the current passing through the conductive film will change, which is read by the detection circuit. Of course, this voltage is related to the touch point. The location is related. According to the voltage read from the horizontal and vertical directions, it can be converted to the X and Y coordinate position of the touch point, and then the actual coordinate value of the finger on the whiteboard plane can be obtained. The processing chip on the circuit transmits the data to the computer through the communication cable, and then realizes the mouse operation function through the driver of the operating system layer. In the same industry, the resistance pressure sensitive whiteboard products are the earliest on the market, and the product maturity is high. The market share of all types of interactive whiteboards has exceeded 70%.

Speaking of resistive pressure sensitive interactive smart whiteboards, we cannot fail to mention the representative brand of this camp-Canadian SMART company, which is the world's first interactive smart whiteboard manufacturer. It has been Focusing on the field of interactive smart whiteboards, with mature technology, all of its whiteboard products have passed the most stringent EU RoHS certification and Canadian CSA certification to ensure product safety, environmental protection and no radiation. At the same time, SMART has also obtained the WQC World Teaching Aid Association quality license certification, which is known for its high standards and strict requirements, with its high-quality and efficient product performance, low-energy environmental protection design concept, and strong after-sales support system. The impact will not cause any damage to the product. In addition, the product is made of RoHS-certified green environmental protection materials, coated with polyester materials, and compatible with water-based markers, which not only optimizes the projection effect, but also effectively protects the vision of teachers and students, and truly cares for the health of teachers and students. Therefore, SMART whiteboard products have been widely used in domestic key primary and secondary schools and training institutions.

　　 Children are the hope of parents and the hope of the country. The all-round improvement of teaching level is an indispensable ladder to a better future, and the foundation of this ladder is a healthy body. In a happy classroom composed of teachers and children, please be sure to keep environmental protection concepts and environmentally friendly teaching equipment with them for a long time to create a healthy and happy teaching environment for them.

Daily maintenance

　　 1. Avoid hitting the interactive whiteboard with hard objects

　　2. If you need to clean the board surface, you can wipe it with a damp cotton cloth without dripping water, and then wipe the board surface with a dry cloth

　　 daily use

　　 1. It is strongly recommended that users read the manual carefully before use and watch the attached "Interactive Whiteboard Quick Training Course".

　　2. When writing with an interactive whiteboard pen, please use a little more force.

　　3. It may be inconvenient to use the interactive whiteboard marker to click or double-click at the beginning. Please do appropriate exercises in advance. Practice makes perfect.

　　 4. When facing students, please stand on the side of the interactive whiteboard to prevent the projector beam from irradiating your eyes.

　　 5. When students use the interactive whiteboard, please instruct them how to use it.

　　6. Warn students not to look directly at the beam emitted by the projector.
