Description

TECHNICAL FIELD

[0002] The elevator light curtain is a light type elevator door safety protection device, which is suitable for various elevators such as passenger elevators, freight elevators, etc. It is used to protect the safety of passengers entering and leaving the elevator. The device forms a dense infrared protection light curtain through the infrared emitter and receiver installed on both sides of the elevator car door, as well as the corresponding power box and special flexible cable and other components. When any object enters this light curtain area and blocks the light, the control system will immediately output an open door signal to stop the elevator car door from closing and reverse to open, thereby avoiding the occurrence of elevator trapping accidents. The working principle of the elevator light curtain is based on the photoelectric sensing principle. There are multiple infrared emitter tubes in the emitter, which are opened in turn under the control of the micro control unit to continuously scan the car door area from top to bottom. At the same time, the multiple infrared receiving tubes in the receiver correspondingly receive the light emitted by these emitter tubes. When any one of the light beams is blocked, the light curtain will judge that there is an obstruction and output an interrupt signal. After receiving this signal by the control system, the open door action will be triggered immediately to ensure the safety of passengers. After the production of the elevator light curtain is completed, its performance needs to be tested.
