CRIMEDISASTERS PREVENTION UNITY SYSTEM USED RADIO NETWORK

摘要

PURPOSE: A crime prevention/disaster prevention integrated system using radio network is provided to take a speedy disposal when a special subscriber transmits the emergency signal, by constructing LAN(Local Area Network) between neighbors and by linking with neighbors by radio network and to enhance the safety, economy and convenience when the subscriber uses a local loop, by linking radio network with dedicated line. CONSTITUTION: A crime prevention/disaster prevention integrated system using radio network comprises an emergency sensor(1), a signal transmitter(2), a signal receiver, a radio network relay(4), LAN(Local Area Network)(5) and a situation room(6). The subscriber constructs LAN(5) with a local loop or dedicated line. The emergency sensor(1) informs the emergency situation such as fire or thief break-in of the subscriber. The signal transmitter(2) transmits the emergency signal to the outside for asking the help. The signal receiver receives the outputted emergency signal from the signal transmitter(2) of the subscriber connected to the radio network. The radio network relay(4) transmits the emergency signal to the signal receiver and the situation room(6) according to the emergency signal. When the emergency signal is generated on the signal transmitter(2), the partner signal receiver displays the emergency signal, because the signal transmitter(2) is endowed with the characteristic address.
