Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Referring to fig. 1, an embodiment of the present invention includes:

an intercom system with a hoistway lighting control function comprises an intercom, a lighting switch, a hoistway lighting relay 3 and a hoistway lighting lamp 4.

The interphone comprises an interphone main machine 11 and an interphone sub-machine 12, and the lighting switch comprises a machine room well lighting switch 21 and a pit well lighting switch 22.

The intercom host computer 11, computer lab well lighting switch 21 and well lighting relay 3 correspond and set up in the computer lab, the intercom parasite aircraft 12 corresponds with pit well lighting switch 22 and sets up in the pit, well light 4 corresponds and sets up in the elevator well.

The talkback main unit 11 and the talkback sub unit 12 are correspondingly connected through the communication line 5.

The intercom main machine 11 is correspondingly connected with a coil of the hoistway lighting relay 3, and the machine room hoistway lighting switch 21 is correspondingly connected with a contact of the hoistway lighting relay 3.

The intercom slave unit 12 is correspondingly connected with the pit hoistway lighting switch 22.

The machine room well lighting switch 21, the well lighting relay 3 and the well lighting lamp 4 correspondingly form a well lighting loop.
