When explaining the main operation and operation principle of the emergency bell system of the underground parking lot according to the present invention configured as described above in detail.

First, an application program generating an emergency call signal to the user terminal 10 is downloaded from a web server such as Google Market, Apple Store, etc. through a communication network (data communication) or downloaded and installed through a memory device such as USB.

Thereafter, the app APP of the user terminal 10 is executed according to the user's execution command or the wakeup signal received from the wakeup signal generator 20, and the emergency bell unit 40 is activated while the short range wireless communication function is activated. And it is switched to a state capable of transmitting and receiving data with the integrated management server 50.

At this time, the app (App) of the user terminal 10 may be displayed a variety of icons that can handle the emergency situation. For example, as shown in FIG. 5, the bell pressing icon may be displayed with the phrase “Do you want to ring the emergency bell?”, And when the user touches the bell pressing icon, the system generates an emergency signal and generates a Bluetooth signal. By using the short-range wireless communication function such as automatically connected to the surrounding emergency bell unit 40 and transmits as a beacon signal or BLE communication signal, the icon during positioning with the phrase "emergency bell ringing" may be displayed.

When an emergency occurrence signal is generated from the user terminal 10, the emergency bell units 40 located at a distance capable of wireless communication therewith receive an emergency occurrence signal through respective short range wireless communication devices 41, Based on this, an emergency occurrence signal is generated and notified to the integrated management server 50, and at the same time, the camera 44 is controlled to obtain surrounding surveillance image information and transmitted to the integrated management server 50.

In this process, the emergency call signal receiving unit 51 of the integrated management server 50 receives a signal transmitted from the emergency situation occurrence notification unit 43 of the emergency bell unit 40 and transmits it to the emergency signal generation unit 52. The emergency signal generator 52 automatically generates an emergency signal and transmits the emergency signal to the emergency signal transmitter 53. The emergency signal transmitter 53 transmits an emergency signal to a terminal carried by a manager or worker. Send a signal.

In addition, the positioning unit 57 uses the measured value of the RSSI value measuring unit 49 to determine the exact position of the user terminal 10, and uses the position tracking unit 54 as the location information of the user terminal 10. And the location tracking unit 54 tracks the location of the user terminal 10 and transmits the location to the camera controller 56, and the camera controller 56 captures the photographing position of the camera 44 based on the tracked location information. Control in real time.

Subsequently, the image captured by the camera 44 is signal-processed by the image acquisition unit 45 to generate surveillance image information, and the generated surveillance image information is stored in the image storage unit 55.

At this time, the three emergency bell units 40, 40-1 and 40-n respectively measure the received electric field strength (RSSI) of the signal received from the corresponding user terminal 10 to determine the individual emergency bell unit (40). After calculating the distance with (40-1) and (40-n), the coordinate value can be obtained, and the moving path can be identified and tracked.

In this case, the integrated management server 50 can quickly confirm the emergency occurrence place based on the location information of the location positioning unit 57 and the location tracking unit 54, and monitors the surveillance image automatically transmitted in real time. You can quickly respond by dispatching a manager or worker (guards) to the location while displaying on the screen.

Meanwhile, the emergency signal generation signal transmission mode of the user terminal 10 may be switched when the user presses a preset button on the user terminal 10.

In addition, the emergency bell unit 40 may check the presence or absence of the emergency situation. That is, the emergency bell unit 40 may release the emergency notification mode upon receiving the emergency release command signal from the integrated management server 50 or the like.

In addition, the integrated management server 50 lights and flashes or lights the LED light source module 61 installed on the emergency occurrence place and the movement path based on the location information of the location positioning part 57 and the location tracking part 54. Dimming control enables quicker and more effective identification of the emergency location.

In addition, when the emergency call signal is generated from the user terminal 10, the integrated management server 50 controls the electric switch 80 to operate the door or shutter for opening and closing the doorway in the parking lot to close and block the doorway in the parking lot. This can prevent criminals from escaping.

On the other hand, the parking position register 58 is usually the received electric field strength (RSSI) value of the emergency bell unit 40, 40-1 (40-n) according to the parking position registration response reply through the app of the user terminal 10 The periphery of the emergency bell unit 40 which transmits the maximum value can be registered as a parking position.

That is, by using the marker information of the emergency bell unit 40 can be registered and updated with the current location information of the user terminal 10.

For example, as shown in FIG. 6, a registration icon may be displayed along with the phrase, "Do you want to register the current location as a parking location?", And when the user touches the registration icon, the parking location registration signal is generated. After using the short-range wireless communication function such as Bluetooth automatically connected to the surrounding emergency bell unit 40 and transmits as a beacon signal or BLE communication signal, parking with the phrase "registered parking position is B1A07 B1A07 basement." A location icon can be displayed so you can easily see where your vehicle is parked.

On the other hand, the present invention is not limited by the above-described embodiments and the accompanying drawings, and various modifications and applications that are not illustrated within the scope not departing from the technical spirit of the present invention, as well as of each component It is apparent to those skilled in the art that the present invention may be widely applied by changing to other embodiments equivalent to substitution.
