Abstract

The utility model relates to an anti-theft and anti-robbing remote-controlling cipher safe which is composed of a safe body, an electronic device in the safe body and an accompanying controller. A radio signal is used for communication and control, and a safe machine is provided with a coded signal generator and an emission return circuit which is used for the generation, the modulation and the amplification of a carrier frequencies signal. When the distance between a mobile and the safe machine exceeds a safety distance which is set, the receiving device of the mobile sends out to alarm and buzz in order to remind the master of the safe to warn. When the cipher safe is found to be stolen and robbed, the mobile sends out a coded signal to cause the receiving device of the safe machine to emit sound for alarming and generate high voltage with 10 to 15 kV after the receiving device receives the coded signal so that an evildoer loses motion ability in short time. The utility model has the advantage of high safety, and is an ideal safe for people storing valuable articles.
