an automatic door

Abstract

The invention provides an automatic door. The automatic door comprises a door frame, a door fan movably connected with the door frame, and a driving unit for driving the door fan to move, and further comprises a light-emitting unit, a sensing unit and a control unit, wherein the light-emitting unit emits visible light; the light emitted by the light-emitting unit faces to a direction entering the automatic door and forms an included angle of 30-90 degrees with the horizontal direction; the sensing unit receives the light emitted by the light-emitting unit and sends out a signal; and the control unit controls the driving unit to drive the door fan to move according to the signal sent out by the sensing unit. The automatic door works in a way of sensing the visible light, the automatic door can be opened when the visible light enters the sensing range of the automatic door, and the automatic door is not closed within the sensing range, so that injury caused by mistaken closing is avoided; the used visible light is clean energy, so that no damage is caused; and the visible light can supply lighting, so that the utilization rate of resource is improved.

Description

technical field [0001] The invention belongs to the control field, and in particular relates to an automatic door. Background technique [0002] Nowadays, the degree of automation and informatization is getting higher and higher. With the development of society, the advancement of science and technology and the gradual improvement of people's living standards, various automatic control systems that are convenient for life have begun to enter people's lives, and the automatic door system is one of them. one. The automatic doors of traditional buildings or shopping malls are automatically opened and closed through infrared induction systems, which have certain requirements on the height of people. When children approach the automatic doors, the automatic doors may not work, or when children follow adults through the automatic doors Due to the premature closing of the automatic door, the situation of entrapment and injury of children occurs. [0003] Therefore, the existing a...

The automatic doors of traditional buildings or shopping malls are automatically opened and closed through infrared induction systems, which have certain requirements on the height of people. When children approach the automatic doors, the automatic doors may not work, or when children follow adults through the automatic doors Trapped child due to premature closing of automatic door

[0003] Therefore, the existing automatic doors have factors of unstable work, which may cause injuries. However, the infrared induction method used more now has no conclusions about whether the infrared radiation will cause harm to people. A safer method is needed. The way to achieve the effect of the existing automatic door controlled by infrared sensor
