Multimedia broadcasting device with human sensor

Abstract

A multimedia broadcasting device with a human body sensor comprises a display, a driver, a power supply, a control module, a power switching module and a sensing circuit, and the sensing circuit comprises a sensing chip, a battery, a capacitor, a first DC / DC module, a second DC / DC module, a signal output end and a common grounding unit, wherein the signal output end is used for outputting control signals. The multimedia broadcasting device with the human body sensor keeps the sensing function of the human body sensor, the appearance of the device is unaffected by installation of the human body sensor, and the human body sensor is suitable for being installed on the front surface of the device. Particularly, by the aid of the sensing circuit, energy consumption is reduced when the multimedia broadcasting device is in a standby state, standby current is about 10 microamperes, and the standby power consumption of the multimedia broadcasting device is further reduced.

Description

technical field [0001] The invention relates to a device with a human body sensor, and also relates to a multimedia broadcasting device with a human body sensor. Background technique [0002] With the development and progress of society, the consumption of resources is becoming more and more serious. Therefore, resources have been raised to a new level of attention by people. Therefore, the country and society have been advocating low-carbon life production, and the electric energy in it saving is particularly important. [0003] Nowadays, people have various ways of entertainment. Audio-visual equipment, especially video equipment, is often used by people. When watching and listening, people will leave suddenly, and these devices are still consuming power. This is true in mobile audio-visual equipment The performance is particularly prominent, such as the audio-visual programs installed in taxis for passengers. [0004] Human body sensing devices are also installed on som...
