Calibration method and system for proximity sensor

Abstract

The invention relates to a calibration method and system for a proximity sensor. The method comprises the following steps: after a calibration command is received, calibrating the proximity sensor according to calibration data stored in terminal equipment; after calibration, acquiring currently generated calibration data and judging whether the calibration time is longer than a threshold value or not; and if so, updating the calibration data stored in the terminal equipment according to the currently generated calibration data . According to the method and system provided by the invention, whether the calibration data is stored or not is judged according to the calibration time. When the calibration time of the proximity sensor is relatively long, the original calibration data is replaced by the currently generated calibration data to realize update of the calibration data so as to provide the calibration data which is more suitable for a terminal equipment using environment, so that the calibration time next time is shortened, the response speed of the proximity sensor is improved, and the user experience is improved.

Description

technical field [0001] The invention relates to the technical field of equipment debugging, in particular to a calibration method and system for a proximity sensor. Background technique [0002] For a terminal device with a touch screen (such as a capacitive touch screen mobile phone), it is easy to cause misoperation due to the user's touch. For example, when using a mobile phone to make a call, it is easy to cause misoperation due to the touch of a human face. Therefore, in order to solve such problems, proximity sensors have appeared on some terminal devices at present. When an object is detected approaching the terminal device, the terminal device is triggered to take corresponding protection actions to avoid misoperation. The proximity sensor includes an infrared transmitter and multiple infrared receivers. The infrared light emitted by the infrared transmitter is reflected by the object and then received by the infrared receiver. Therefore, it can be judged whether the...

Problems solved by technology

Calibration is performed every time the proximity sensor is turned on in the terminal device. However, the calibration work cannot be done overnight and takes time to perform. Currently, the calibration work of the proximity sensor is based on the calibration data saved in the engineering mode. In fact, the proximity sensor It is often disturbed by environmental factors such as oil pollution. If each calibration work is based on the calibration data saved in the engineering mode, the calibration time will be longer, the status reporting time of the proximity sensor will also be longer, and the user experience will be worse.
