Abstract

An electrostatic warning module attached to electronic equipment, which includes a power supply, a signal amplifying device, a triode and an alarm; the signal amplifying device is an operational amplifier, the power supply supplies power to the operational amplifier, and the positive The phase input terminal is electrically connected to the electronic device, the inverting input terminal of the operational amplifier is connected to the negative pole of the power supply, the output terminal of the operational amplifier is connected to the base of the triode, and the collector of the triode is connected to the positive pole of the power supply through the alarm The emitter is connected to the negative pole of the power supply. When the amount of static electricity carried by the human body or objects is too small to pose a threat to electronic equipment, the operational amplifier does not respond; if the static electricity is large, the operational amplifier outputs a high level. By turning on the triode, the siren sounds as a warning of excessive static electricity. The static electricity warning module can detect excessive static electricity that is harmful to electronic equipment, and sends a warning through an alarm to remind operators to pay attention, thereby improving the safety of 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...
