FPGA (Field Programmable Gate Array) based angle and distance reminding device

Abstract

The invention discloses an FPGA (Field Programmable Gate Array) based angle and distance reminding device. The FPGA based angle and distance reminding device comprises an FPGA processor, a tilt angle sensor, an infrared distance sensor, an image sensor, a storage unit, a voice unit, a display unit and a power supply module; the image sensor is used for performing the human face recognition and determining the positions of human eyes; the display unit is used for displaying a deviation value of a numerical value of the actual angle and distance and a standard value; the power supply module is used for supplying the power for the integral device; the FPGA processor is used for receiving the human eye position information detected through the image sensor and transmitting the information to the infrared distance sensor, receiving the tilt angle information of an electronic product and the information of the distance between the human eyes and the electronic product, performing comparison on the information and standard data pre-stored in the storage unit when the tilt angle variation and the distance variation are maintained within an allowed range and displaying a final deviation result on the display unit, wherein the tilt angle information of the electronic product is detected through the tilt angle sensor and the information of the distance between the human eyes and the electronic product is detected through the infrared distance sensor; the voice unit is used for giving an audible alarm when the deviation value exceeds the allowed range.

Description

technical field [0001] The invention relates to an FPGA-based angle and distance reminding device, which belongs to the field of electronic appliances. Background technique [0002] According to the data of the International Telecommunication Union, the number of mobile phone service subscribers in the world is currently 6.8 billion. Due to the popularity of smart phones, the number of people who keep their heads down and focus on mobile phones is growing. According to experts, long-term "lower head" is the most likely to cause cervical spondylosis, and it will bring a series of symptoms, including dizziness, nausea, cataplexy, skin numbness on the back of the neck, arm pain, finger numbness, etc., and even lead to high blood pressure, heart disease, etc. Symptoms that seem to have nothing to do with the cervical spine, such as diseases, visual disturbances, breast pain, and swallowing disorders. [0003] Most of the smart phones or PAD electronic devices currently on the m...

Problems solved by technology

[0004] In order to overcome the lack of existing electronic products in reading text, watching video, and processing documents, the equipment that monitors and reminds the actual distance and inclination angle from the human eye to electronic devices such as mobile phones, PADs, and monitors cannot effectively intervene and remind users to adjust their posture. , can not effectively help users maintain the correct distance and angle when operating electronic equipment such as mobile phones, PADs, and displays. The present invention provides an FPGA-based angle and distance reminder device
