Problems solved by technology

[0004] However, the above-mentioned devices also have deficiencies. For example, the tables and chairs for preventing myopia are inconvenient to move, and it is difficult to meet the simultaneous use of students, schools and families; the correction belt restricts the user's activities; Portable; at the same time, this kind of contact device is not easy to form a habit, and it is easy to return to an incorrect posture without the device; infrared rays need to emit and receive devices; light control is limited by the location and environment, etc.
In addition, some devices also have problems such as complex structure, high cost, and easy misjudgment.

Abstract

The invention discloses a method and a device for preventing myopia based on ibeacon. The method comprises steps of: obtaining, by a receiving module, a broadcast signal frame sent by an iBeacon module, and acquiring an RSSI value therein; calculating an instantaneous distance between the iBeacon module and the receiving module according to the RSSI value and the intensity of the signal received by the receiving module; sampling and recording the instantaneous distance value in a first predetermined time interval, and calculating the distance average value in the first predetermined time interval; according to the height of a monitored person and the heights of the table and the chair, obtaining a first recommended distance value by calculation; and issuing alarm information according to the absolute value of the difference between the distance average value and the first recommended distance value, the alarm information being different according to the magnitude of the absolute value.The method and the device have the advantages of simple structure, convenient operation and easy carrying, and can appropriately remind the monitored person to prevent the occurrence of myopia.

Description

technical field [0001] The invention relates to the technical field of myopia prevention, in particular to a myopia prevention reminder method and device based on an ibeacon device. Background technique [0002] Myopia has become a "national disease" in my country. According to the "National Vision Health" white paper released on June 6, 2016, it is pointed out that among the people over the age of 5 in my country, 1 out of every 3 people is myopic. Among the total population over the age of 5, the proportion of myopia is 35.16% to 39.21%, and the total number of patients with myopia is between 437 million and 487 million. Among them, the proportion of high myopia is between 2.33% and 2.47%. The total population of China is as high as 29 million to 30.4 million. The white paper also pointed out that if effective policy interventions cannot be adopted, it is estimated that by 2020, the incidence of myopia among the population over 5 years old in my country will increase to 5...
