Abstract

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.

Description

Integrated crime prevention and disaster prevention system using wireless network {CRIME, DISASTERS PREVENTION UNITY SYSTEM USED RADIO NETWORK}

The present invention relates to a crime prevention and disaster prevention device that informs it when an external invasion or fire occurs to prevent property loss and accidents, and in particular, establishes an emergency communication network by radio waves between neighbors and sends a help request signal in case of emergency. The present invention relates to a crime prevention and disaster prevention integrated device using a wireless network system.

Currently, a number of crime prevention and disaster prevention devices have been disclosed that connect emergency signals such as homes and offices and signal destinations such as police departments and security service providers to transmit emergency signals in case of an emergency.

In recent years, security and disaster prevention apparatuses using modems, which are data communication devices, which function to receive digital signals from computers and convert them into analog signals for transmission over telephone lines in accordance with the general use of the Internet, have also been disclosed.

In this manner, a modem is divided into a dial-up modem based on a switched line such as a general telephone and a leased line modem for a leased line.

However, such a crime prevention and disaster prevention device has a problem in that the response time due to the movement of the police department or security company is delayed when the distance between the emergency signal transmitter and the emergency signal receiver is relatively far.

In addition, since the means for transmitting the emergency signal is connected by wire, there is no means for transmitting the emergency signal when the trunk line is cut by an intruder, so that it is impossible to cope with the threat of personal injury or safety accident.

In addition, in the case of using the leased line, while providing convenience and safety to the user, there is a problem in that the subscriber has to pay a small monthly fee to add a burden to the user.

The present invention is to solve this problem, to establish a local area network between neighbors living in the near area, and to be connected to the wireless network so that both trunk lines and leased lines can be used to make a quick action when sending an emergency signal from a particular subscriber The purpose is to provide an integrated security and disaster prevention system using a wireless network.

Another object of the present invention is to provide a security and disaster prevention integrated system using a wireless network that can implement the convenience and safety of the leased line at the same level at a low price even when using the trunk line by connecting the wireless network to the leased line. .

The present invention for achieving the above object is to install an emergency detector, a signal transmitter and a signal receiver in each of the subscribers located in close proximity to the wireless network to enable mutual transmission of emergency signals in case of emergency, the information detected by the emergency detector The signal transmitted from the signal transmitter according to the present invention is characterized in that it is transmitted by the wireless network repeater to the near subscriber and the operating room subscribed to the wireless network through a compromised signal path of trunk lines or leased lines.

Hereinafter, a security and disaster prevention integrated system using a wireless network according to the present invention will be described according to the embodiment shown in the accompanying drawings.

1 is a block diagram illustrating a security and disaster prevention integrated system according to the present invention, assuming that a limited number of wireless network subscribers (hereinafter, abbreviated as "subscribers") of a certain area is n, each subscriber is a trunk line Alternatively, a local area network (5) may be established by a dedicated line, and each subscriber may detect an unexpected situation such as an external intrusion or fire, and detect and notify the user of the emergency detector (1). A signal transmitter (2) for transmitting an emergency signal to the outside for a user's request for help by a signal sensed from the signal receiver, and a signal receiver for receiving an emergency signal transmitted from a signal transmitter (2) of a user joined to the same wireless network. (3) will be installed.

It also comprises a signal receiver 3 of other subscribers and a wireless network repeater 4 which transmits an emergency signal to the situation room according to the emergency signal transmitted from the signal transmitter 2 of the specific subscriber. At this time, the wireless network repeater 4 is connected to the dedicated line to ensure the maximum safety even for the trunk line users.

On the other hand, the frequency of the signal transmitter 2 and the signal receiver 3 is unified, but the signal transmitter 2 is assigned a unique address so that when the emergency signal is generated in the signal transmitter 2, the signal receiver 3 of the other party It should be displayed on the screen so that the subscriber who sent the emergency signal can be easily identified. At this time, it is preferable that the signal transmitter 2 is installed in a portable device, for example, a watch, so that the user can always carry it, so that a quick response can be made in an emergency.

FIG. 2 illustrates an embodiment of an integrated crime prevention and disaster prevention system of the present invention, and establishes a local area network between wireless network subscribers located in a predetermined neighborhood, and each subscriber is associated with an operation room 6.

In other words, assuming that the local area network is composed of n subscribers, if the subscriber 1 operates the signal transmitter 2 when a thief intrudes or a fire occurs in the subscriber 1's house, the wireless network repeater 4 ) Transmits an emergency signal to subscribers 2 to n, and also transmits an emergency signal to the situation room 6 by negotiating a signal path.

At this time, when the trunk line of the subscriber 1 is cut, conventionally, there was no means for delivering an emergency signal to a police department or a security company. The wireless network repeater 4 transmits the signal path of the leased line to the situation room 6 so that the emergency signal transmission can be assured. In addition, the police station or the security company through the situation room 6 as described above. Other subscribers living in close proximity will also be able to help eliminate the risk quickly.

In addition, when using a conventional leased line, each subscriber had a burden of paying a small monthly fee. However, in the state of constructing the wireless network of the present invention, the monthly rate is set by connecting a plurality of trunk line subscribers to one leased line. By dividing and paying the same, the burden on subscribers can be minimized.

As described above, according to the present invention, by connecting a wireless network system to a dedicated line, the current trunk line terminal is searched in real time, and the situation control is controlled in the same concept as the dedicated line, thereby real-time processing in case of theft, topic, and other similarities. Becomes possible.
