Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to an emergency call apparatus and method,

The present invention relates to an emergency communication apparatus and method, and more particularly, to an emergency communication apparatus and method in which when an emergency situation occurs in a room or an elevator in a specific area, an occupant receives an external interphone provided in the management room without a series of procedures, The mobile phone number of the corresponding manager registered through the wireless connection device (a modem built in the 4G or 3G wireless access device) connected to the existing CO line PSTN telephone through the emergency call device or replacing the CO line with the emergency call device To an emergency communication device and a method for notifying an emergency situation and requesting a structure of the emergency communication device.

An elevator emergency call device and method is disclosed in Patent Registration No. 10-0859756. When an elevator is abruptly stopped or a power failure occurs or an error occurs during operation, an emergency call button in the elevator is pressed to make an external telephone call Thereby making it possible to quickly structure and cope with it.

The elevator emergency call device is provided with an interphone function and a telephone connection function in one terminal, so that when an emergency situation occurs in the elevator car, it is possible to communicate with an interphone of a security room or a management room, It is possible not only to quickly cope with an emergency but also to prevent the misuse of the emergency call operation by being performed only when the connection with the external telephone meets a certain condition. In an emergency communication device for use in an emergency situation in a power failure and a failure situation of an elevator, an underground parking lot, and the like, most emergency communication devices use a method of making a call using a PSTN (general telephone line).

In the case where the emergency call is made using the PSTN, when the coloring is set in the incoming telephone, the emergency call device can not determine whether the called party has received the telephone, Multi Frequency) tone, for example, '1', so that the called party is aware that the call is received. In addition, when the called party first hangs up, Busy Tone is transmitted to the emergency call device, so that it is generally configured to detect the call and terminate the call.

However, the above-mentioned prior art has the following problems.

1. Acknowledgment of call connection

When a called party receives a call, a broadcast message requesting a DTMF to notify the caller is continuously transmitted, so that there is a trouble in the call of the called party.

If the emergency call device uses a 3G or 4G mobile telephone network instead of a PSTN trunk, DTMF transmission is not possible when the mobile phone receives a DTMF transmission within the same network because the DTMF transmission is not possible within the same network. (According to the 3GPP standard, since the same voice codec is used in voice communication between mobile phones in the same network, the coding process for DTMF transmission is omitted.) However, 3G / There is no problem with DTMF transmission since different voice codecs can be used in 4G terminal and heterogeneous network communication).

2. Busy Tone Recognition Problem at the end of a call due to termination of an incoming call

When the call is terminated by the incoming call, the emergency call device recognizes the busy tone interval and normally terminates the call (hook-off operation in the ordinary telephone). However, the distance between the place where the emergency call is installed and the telephone station, The waveform of Busy Tone changes according to different conditions such as manufacturer and type, which implies possibility of malfunction.

If the call is not terminated normally by Busy Tone for the above reasons (Hook off as in normal phone), the emergency call device will continue to send Busy Tone. So that further calls can not be made. Also, in case of the emergency communication device installed in the elevator, the passengers trapped in the elevator hear the busy tone continuously, which may increase anxiety.

However, the emergency call device of the elevator of the existing elevator operating section is connected to the interphone and the PSTN trunk line telephone with a maximum of 2 channels. However, when there is no person in charge of the management room, the emergency call device It did not provide wired / wireless integration.
