Abstract
The utility model relates to a two-wire electric-control intercom for anti-theft door in the building. The two-wire electric-control intercom for anti-theft door in the building is composed of a main frame and a plurality of receiver. The main frame is composed of a code sending circuit, a receiving circuit, a timing circuit, a lock driver circuit, and a communication circuit. The circuit of each receiver is same. The circuit of each receiver is composed of a decoding circuit, a time sequence circuit, a power supply control circuit, and a communication and code sending circuit. The circuits of receivers can code, decode, emit in both-direction, and receive in both-direction. The mainframe and each receiver share with two input and output transmission lines as signal lines.
Description
The utility model relates to the automatically controlled talkback unit of antitheft door of a kind of building residence.
The automatically controlled talkback unit of existing building residence antitheft door exists in following deficiency:
1, on line is loaded down with trivial details: the on line of subscriber's extension station and main frame has five, and wherein four is that all users are public, and one is every user's special use.On line between main frame and the subscriber's extension station just reaches the N+4 root like this.N is resident family's number in this building in the formula.Suppose that certain building has 14 users, every on these lines were sat in the right seat when the on line between main frame, the extension set will reach 1 installation, maintenance of 14+4=18 root so, do not allow misconnection, missed.Therefore, the user who contacts this device installation for the first time feels that installation, maintenance is very tired.
2, unfavorable maintaining secrecy:, the certain user is abhored as long as whichever user mentions the dialogue that the mobile phone of extension set can be heard doorway and other user.
3, function is less: generally automatically controlled only unblanking.Certain this product even can only drive a lock makes same unit building and user with two doors uses inconvenience.
4, doorway machine badly often causes part fails such as button to cause fault owing to environment for use.
5, the button in a family is unsuitable for the many situations of skyscraper user.
6, the domestic market still has only a few to adopt the product of four bus systems.This is an improvement to the extension set that adopts five lines, sits in the right seat yet these four buses remain, and can not make a mistake.
