Specific embodiment

As Figure 1-Figure 5, a kind of outer hung type myopia prevention device, including main board 1, core is respectively equipped with main board 1 Module, range finder module, time block, reminding module, charging module and stuck-module.

Nucleus module includes single-chip microcomputer 4, using STC15W single-chip microcomputers as the control section of single unit system, has been foretold with C Into programming, with STC-ISP softwares write-in single-chip microcomputer.Single-chip microcomputer 4 connects range finder module, time block, prompting mould respectively Block, charging module.

Range finder module uses infrared distance measurement mode, including RF transmitter 6, infrared receiver 8 and stopping means 5, stopping means 5 is limiter, adjustment RF transmitter 6, the detecting distance of infrared receiver 8.

Time block includes timer 3, timing button and timing indicator 9, in order to reduce the weight of whole device, can set Meter was the time timer of radix with 10 minutes, often by a timing button, the corresponding red LED timing indicator of timing button It is bright once, timing increase by 10 minutes, regularly terminate rear reminding module send point-like laser prompting timing terminate.

Reminding module includes point-like laser transmitter 7, its red light spot signal stabilization, will not dissipate, and in any light Can ensure clear under line.

Charging module includes battery 10 and USB charging inlets 2, and battery uses compact lithium cell, using USB charging modes, Compact lithium cell is directly connected on single-chip microcomputer 4.Vcc, GND, D+, D- pin of USB interface connect respectively 5V, GND, Tx and Rx。

5th pin and the 7th pin of microprocessor U1, i.e. single-chip microcomputer 4 are connected to LED light, output digit signals, when drawing Indicator lamp is bright during pin low level, and R6 and R8 is current-limiting resistance, and protection LED is not over rated operational current.14th pin connects To infrared receiving terminal output end, numeral input judges whether to receive corresponding pulses signal, and the 15th pin is connected to laser lamp, output Data signal, when pin low level, indicator lamp is bright, and R7 is current-limiting resistance, and protection laser lamp is not over rated operational current. 16th pin is connected to infrared transmitting tube, exports digital modulation pulse signal, and R9 is current-limiting resistance, protects infrared emission spot not Rated operational current can be exceeded, RP1 can adjust infrared transmitting tube brightness.
