The automatic alarm protection function of the electric zoom lens is mainly realized through the built-in sensor and control card. Specifically, when the lens has abnormal conditions during use, such as mechanical failure, overheating, etc., the sensor will detect these abnormalities and transmit signals to the control card. The control card determines whether an automatic alarm needs to be triggered based on the preset alarm threshold and protection strategy. If an alarm is required, the control card will output an alarm signal to remind the user that there is a problem with the lens.
In addition, in order to protect the lens from mechanical failure, the electric zoom lens also adopts automatic alarm protection technology. When the lens encounters resistance or abnormal conditions during zooming or focusing, the control card will immediately stop the lens and output an alarm signal. This protection technology can effectively reduce the impact and friction on the lens and extend the service life of the lens.
The automatic alarm protection function of the electric zoom lens is based on the cooperation of the sensor and the control card. These devices monitor the status and usage of the lens and trigger automatic alarms when needed, thus protecting the lens and avoiding mechanical failure.
