What are the routine maintenance of mathmatic model
1. The mathmatic model wire connector inspection
Wires with loose connectors will cause high temperature at the connector position and damage the mathmatic model. Poor connectors will also affect data transmission; the connectors on the monitor will be easier to loosen due to moving the monitor angle, so it is necessary to regularly check the position of the wire connector and the retraction. tight.
2. Circuit board
Dust accumulation will cause heat dissipation difficulties, so the mathmatic model should be cleaned regularly every month. Usually, a motor overload circuit breaker is installed in the circuit. The limited current of this protection device is adjustable, and an appropriate choice should be made according to the rated power of the equipment. Once the overload protector is activated, it should be determined to check whether there is a phase loss or a bad contact before pressing the reset switch.
3. Headphones and keyboard
In teaching, the use of digital language learning system must use supporting equipment—earphones and keyboards. Generally speaking, these supporting equipment are relatively easy to be damaged. The school voice room is used a lot, and it is frequently used, which is easy to cause damage, so it needs to be maintained frequently. Check and replace damaged equipment in time so as not to affect teaching.
4. Computer control part
With the development of science and technology, the normal operation of the microcomputer part and its related electronic boards has put forward higher requirements for the fluctuation of the power supply voltage, the temperature and humidity of the working environment, the vibration resistance of the installation and the interference of external high-frequency signals. To keep the fans used for ventilation and heat dissipation in the mathmatic model work normally, and use a high-precision power supply voltage regulator for power supply, these problems should be effectively solved and the mathmatic model should be checked regularly.
