Embodiment Construction

[0047] The technical solution of the automatic external defibrillator and its display screen brightness adjustment method and device will be described in detail below in conjunction with specific embodiments and accompanying drawings, so as to make it more clear.

[0048] like figure 1 As shown, in one embodiment, a method for adjusting the brightness of a display screen includes the following steps:

[0049] Step S110, collecting ambient light intensity values ​​at a preset frequency.

[0050] In this embodiment, the brightness of ambient light is collected at a preset frequency to find changes in the brightness of the environment, and the brightness is represented by illuminance. Illuminance is a measure of brightness, the unit is lumens / square meter, that is, lux (lux), which indicates the luminous flux received by the unit area of ​​the surface of the subject. The frequency of collecting light intensity values ​​may be preset, such as 1 second / time. Collecting illuminan...

Abstract

The invention provides an automatic external defibrillator, and a display screen brightness adjusting method and apparatus thereof. Illuminance value of an environment is acquired according to a preset frequency, a comparison is made between the illuminance value and a current brightness of a display screen, continuous frequency or time when the illuminance value does not match the current brightness is counted, whether the continuous frequency or the time exceeds a predetermined value is determined, and if so, the current brightness of the display screen is adjusted to match the illuminance value, and the brightness of the display screen is automatically adjusted according to the illuminance of the environment, such that the operation is simplified, the efficiency is improved, at the same time, whether the continuous frequency or the time exceeds a predetermined value when the illuminance value exceeds the predetermined value is calculated as a brightness adjusting condition, and the determination accuracy and stability are improved.

Description

technical field [0001] The invention relates to display technology, in particular to an automatic external defibrillator and a method and device for adjusting brightness of a display screen thereof. Background technique [0002] An automatic external defibrillator (Automatic External Defibrillator, AED) is a portable medical device that can diagnose ventricular fibrillation and deliver electric shocks to correct the patient's heart rate. [0003] The screen brightness of the display of traditional AED equipment is either a fixed value or needs to be manually adjusted by the user. It is inconvenient to view when the ambient light brightness is high or low. Delay in defibrillation can have serious consequences. Contents of the invention [0004] Based on this, it is necessary to provide an automatic external defibrillator capable of simplifying operations and a method and device for adjusting the brightness of the display screen of the automatic external defibrillator for t...
