Abstract

1. TECHNICAL FIELD OF THE INVENTION

Cell system

2. The technical problem to be solved by the invention

In a cellular system composed of a central monitoring controller and a plurality of non-relaying devices, the central monitoring control unit and the unmanned relay device may perform data communication to register and change programs and data in a wired / wireless manner.

3. Summary of the Solution of the Invention

In a cellular system having a central monitoring controller and a plurality of unmanned relay devices, the main program of the relay controller may be changed so that the central monitoring controller may check various alarms and statuses generated by the unmanned relay device. In addition, it improves the operation program of the relay controller to register and change the system ID in the central control unit. In addition, the automatic call number can be registered in the central monitoring controller, and the change can be made immediately upon changing the telephone number, and the central monitoring controller can be called through wireless and wired when an alarm occurs.

4. Important uses of the invention

In the cellular system, the central monitoring control unit and the unmanned relay device perform data communication in a wired / wireless manner to register and change programs and data.
