Embodiment approach

[0042] As an embodiment of the present invention, the specific operation steps of the safety alarm device are as follows:

[0043] Step 1: Pull up the two movable seats 6 on the top along the slide rails of the fixed seat 3. At this time, the slider 13 in the movable groove 10 compresses the spring 12 on the connecting rod 11, and then adjusts and places the cloud desktop smart phone Between the clips 7, the movable seat 6 is released at this time, the spring 12 returns to its original state and then the cloud desktop smartphone is clamped on the movable seat 6;

[0044] Step 2: At this time, when watching the learning video through the smart phone on the cloud table, measure the distance between the learner and the mobile phone through the ultrasonic sensor 9 on the support rod 8. When the distance is less than 30 cm, the control alarm will pass after one minute after an early warning. The ultrasonic sensor 9 measures the distance again. If the measured distance is still less...

Abstract

The invention relates to a cloud desktop smart phone safety alarm device for mobile learning, which comprises a base, a support frame, a fixed seat and a movable seat, and is characterized in that thesupport frame is mounted at the top of the base, the fixed seat is rotatably mounted at the top end of the support frame, the movable seats are slidably mounted at the tops and bottoms of two ends ofthe fixed seat; clamping buckles are mounted on the top side of the top movable seat and the bottom side of the bottom movable seat; when a learner watches a learning video through a cloud desktop smart phone, the distance between the learner and the smart phone is measured through an ultrasonic sensor on a supporting rod, when the distance is smaller than 30 cm, the alarm is controlled to give an early warning, the distance is measured again through the ultrasonic sensor one minute later, and if the measured distance is still smaller than 30 cm, the distance between the cloud desktop smart phone and the eyes is adjusted to be larger than 30 cm, and the eyes of the student are protected.

Description

technical field [0001] The invention relates to the technical field of cloud desktop smart phones, in particular to a cloud desktop security alarm device for mobile learning smart phones. Background technique [0002] Cloud desktop is a service that uses cloud computing to provide virtual Windows desktops and applications. Users can break through the limitations of time, place, terminal, and application, access to cloud desktop office anytime, anywhere, and combine cloud desktop with smart phones.
