Bidirectional transmission converter

Abstract

A bidirectional transmission converter belongs to electric technique field, which uses fixed telephone as carrier, adds three electric circuits as remote-control emission, remote-control receive, and program control circuit on relative keys of base, to realize bidirectional transmission between communication network and remote-control signal. The invention can be engaged with former guard door, which can use mobile phone or fixed phone to automatically control door, wherein when there is open signal, the invention can send a plurality of mobile phone or fixed phone signals to the phone carried by user, to improve safety of guard door. And the invention has low cost, with wide application, clock report and automatic door open functions or the like.

Problems solved by technology

[0003] Judging from the current situation of the market, most of the door locks for security doors are general-purpose mechanical pin locks, which have low performance in operation and security. Obviously, it is difficult to adapt to the performance requirements of social development. Some automatic lock class anti-theft doors have gradually appeared. Although the performance has been greatly improved, many unsatisfactory points are still exposed, mainly in the following aspects: or the door opening method using a mobile phone as a key cannot be realized; or Although it can be realized, it cannot notify users outside in time when there is an extraordinary event; or although it can be notified, it cannot notify multiple users, and the performance is not advanced enough; or although the above objectives can be achieved, the cost is high; or the installation inconvenient wait

One of the main reasons for the above phenomenon is the lack of a bidirectional transmission converter between the communication network system and the remote control network system with comprehensive functions, advanced performance and low cost.
