This application provides a control method, device, smart glasses, medium, and program product for smart glasses. The control method includes: periodically acquiring eye-tracking images of the wearer according to a default cycle using an eye-tracking device during the wearing of the smart glasses; determining the wearer's eye usage data based on the eye-tracking images; adjusting the acquisition cycle of the eye-tracking images based on the eye usage data; and providing eye health reminders. By combining real-time eye usage information with eye health reminders, it is beneficial to improve the eye habits of smart glasses wearers and enhance eye protection. Simultaneously, by dynamically adjusting the acquisition cycle of the eye-tracking images based on eye usage information, eye-tracking image acquisition can be performed at a lower frequency when eye usage is healthy, thereby reducing the power consumption of eye monitoring.

The application introduces a roadside traffic signal data acquisition and processing system and method, wherein the roadside traffic signal data acquisition and processing system comprises: a traffic signal controller for controlling the traffic light at the road intersection; and a signal protocol conversion device for acquiring the data of the traffic signal controller and sending the acquired data to a data center. The signal protocol conversion device comprises a voltage acquisition unit for acquiring the voltage data in the traffic signal controller and a pulse detection unit for acquiring the pulse data in the traffic signal controller, and the voltage acquisition unit and the pulse detection unit are connected with the traffic signal controller respectively. Based on the above system design, the roadside traffic signal data acquisition and processing method designed by the application has the advantages of wide voltage acquisition range, high acquisition frequency, short processing time, wide adaptability and high reliability.
