Problems solved by technology

[0002] In daily activities, the human body and many objects will generate static electricity. If the human body or object with excessive static electricity is close to or touches the electronic equipment, electrostatic discharge will be generated between the human body or the object and the casing of the electronic equipment, resulting in a decrease in the sensitivity of the electronic equipment or even It is possible to break down the components in the electronic equipment and cause damage to the electronic equipment
However, there is currently no device that warns users of the presence of excessive static electricity around electronic equipment.

Abstract

A static warning module is attached to an electronic equipment, including a power supply, a signal amplification device, a triode and an alarm. The power supply supplies power to the signal amplification device, the positive-phase input end of the signal amplification device is electrically connected with the electronic equipment, the negative phase input end of the signal amplification device is connected with the negative electrode of the power supply, the output end of the signal amplification device is connected with the base electrode of the triode, the collecting anode of the triode is connected with the positive electrode of the power supply through the alarm and the emitter is connected with the negative electrode of the power supply. The static warning module can detect the excessive static electricity with damages on the electronic equipment and remind the operator to notice by issuing warnings through the alarm, thus improving the security of the electronic equipment.

Description

technical field [0001] The invention relates to an electrostatic warning module. Background technique [0002] In daily activities, the human body and many objects will generate static electricity. If the human body or object with excessive static electricity is close to or touches the electronic equipment, electrostatic discharge will occur between the human body or the object and the casing of the electronic equipment, resulting in a decrease in the sensitivity of the electronic equipment or even It is possible to break down the components in the electronic equipment and cause damage to the electronic equipment. However, there is currently no device for alerting users to the presence of excessive static electricity around electronic equipment. Contents of the invention [0003] In view of the above, it is necessary to provide an electrostatic warning module that can issue a warning when a human body or object with excessive static electricity approaches or touches an el...
