Telephone incoming call prompt automatic switching method and telephone set

Abstract

The invention discloses a method for automatically switching incoming call prompt mode of a telephone. The method comprises: firstly, realtime detecting whether a telephone set is called, and starting a human body signal detection device when detecting that the telephone set is called; secondly, detecting whether a human being is in a detection range by the human body detection device, and changing the incoming call prompt mode of the telephone set according to the detection result. When the human body signal detection device detects a human being is in the detection range, the incoming call prompt mode of the telephone set is switched to one that can be seen or felt by the user to prevent influencing other people, such as an LED light emission mode or a vibration mode. Otherwise, the incoming call prompt mode is switched to a ring mode to remind the called user. Based on the method, the invention also provides a telephone set having a function for automatically switching the incomingcall prompt mode, which has simple structure and low cost, fully represents the humanized design requirement for telephone set product, and can be widely used in a plurality of occasions.

Description

technical field [0001] The invention belongs to the technical field of communication equipment, and in particular relates to a method capable of realizing automatic conversion of a telephone call prompt mode and a telephone set using the method. Background technique [0002] The human body has a constant body temperature, generally around 37 degrees, and emits infrared rays with a specific wavelength of about 10 μm. The infrared detector works by detecting the infrared rays emitted by the human body around 10 μm. The 10μm infrared rays emitted by the human body are enhanced by the Fresnel filter and then gathered on the infrared sensing source. Infrared induction sources usually use pyroelectric elements, which will lose their charge balance when they receive changes in the infrared radiation temperature of the human body, release charges to the outside, and then convert them into voltage signals for output, so that the presence of the human body can be detected. And send o...

Problems solved by technology

If you use the ringtone reminder method in offices, places with many people and dense telephone calls, it will often affect the normal work of others because the ringtones are very noisy.

And if LED, vibration and other user can see or feel the incoming call reminder, when the called user is not in his seat, but discusses the problem at the seat of his colleagues, it is likely to miss the call
