Automatic optometric head printing base and mobile intelligent terminal charging management method based on same

Abstract

The invention provides an automatic optometric head printing base and a mobile intelligent terminal charging management method based on the same. The printing base comprises a printing base shell and a printer and a printing control circuit which are integrated in the printing base shell, the printing base further comprises a microcontroller, a wireless communication module and a charging module, the microcontroller is in bidirectional connection with the wireless communication module, a first output end of the microcontroller is connected with the control input end of the charging module, and the output end of the charging module is connected with the charging input end of a mobile intelligent terminal of an automatic optometric head; a second output end of the microcontroller is connected with the input end of the printing control circuit, and the output end of the printing control circuit is connected with the printer. The automatic optometric head printing base is simple in structure and low in production cost, the problem that an optometry table is untidy due to charging of the mobile intelligent terminal is effectively solved, a battery of the mobile intelligent terminal can be further protected through the automatic optometric head printing base, and the service life of the battery of the mobile intelligent terminal is prolonged.

Description

technical field [0001] The invention relates to the field of ophthalmic optical inspection instruments, in particular to an automatic optometry head printing seat and a charging management method for a mobile intelligent terminal based on the printing seat. Background technique [0002] The automatic optometry head is a precision instrument for objective optometry of human eyes. It can detect the degree of refractive error of the eyes, including myopia, hyperopia, astigmatism, binocular vision balance, phoria, vision fusion, stereopsis and other visual functions. Provides prescription data for vision testing and prescription of the eye. [0003] The automatic optometry head includes the following parts: optometry head host, printing seat, mobile intelligent terminal and power adapter. The smart mobile terminal is usually used as the control box of the automatic optometry head and placed on the optometry table. The smart mobile terminal is usually a tablet computer. The pow...

Problems solved by technology

If there is no AC socket on the optometry table, the junction box must be placed near the optometry table, which is extremely inconvenient to use, and the workplace appears messy and irregular

[0005] And when charging the tablet computer, the following two conditions also have a great impact on the battery life, one is when the battery power of the tablet computer is not used to a certain value lower than the battery power, it is charged; the second is that the battery is fully charged When the tablet is powered on but the adapter plug is not unplugged, the battery will continue to be charged when the tablet is working, shortening the battery life

Today's tablet computers are all-in-one machines, and it is difficult to open the back cover without special tools. Forcing the cover will only damage the tablet casing

The replacement of the battery can only be performed by the maintenance personnel of the manufacturer, and the user cannot replace it

Therefore, the battery life affects the normal use of the tablet computer, that is, after the battery cannot be charged, the charger can only be used to supply power for the tablet computer, and the convenience of placing the tablet computer at any position is lost.
