Description

Digital recording apparatus for automatic recording of emergency calls {Digital recording apparatus of emergency-telephone}

The present invention relates to a technology for recording / playing an emergency telephone call, and more specifically,

The present invention relates to a digital recording device for automatically recording an emergency call for automatically recording a call through an emergency call in an emergency situation on a highway or an exclusive road.

1 is a schematic diagram showing a call recording method of a conventional emergency telephone. When the handset of emergency telephones 100a and 100b installed on a road such as a highway or a dedicated road is lifted, the optical transmission apparatus 101 in a business office and an optical transmission apparatus in a branch office are shown. The line card 103 of the main exchanger 118 and the trunk card 104 via 102 are connected to the main exchange line card 105 of the main exchanger 118 and the sub-exchange line card of the subsidiary exchanger 119. A telephone ring occurs at the reception desk phone 115 through the 106 and the digital line card 107, and the operator picks up the handset of the reception desk phone 108 to make a call.

At this time, the caller presses the record button of the recorder 109 to record the contents of the call with the other party for later playback.

However, in recent years, the recording contents recorded by the conventional analog recorder 109 are not very secure and can be easily played by anyone, and the recording of the recording contents on the magnetic tape reduces the risk of data loss and retrieval of specific data. There is a problem that is difficult.

The present invention converts and stores the contents of an emergency call in a digital state, and digitally records an emergency call for the purpose of pursuing security, ease of retrieval, ease of storage, and sharing through a network. It is an object to provide a recording device.

Hereinafter, a preferred embodiment of the present invention together with an exemplary drawing will be described in more detail.

The present invention, as shown in Figure 2, for the emergency telephone (20a) and the reception desk on the road through the optical transmission device (1) (2) and the main exchange 18 and the sub-exchange 19 of the office and branch office A digital recording apparatus for automatically recording an emergency call capable of recording contents of a call between telephones (8), wherein a call with one or more emergency telephones (20a) and (20b) through said reception desk telephone (8) Maintenance computer 15 for compressing and storing the contents of calls of various channels input from analog-to-digital converter 17 during calls with analog-to-digital converter 17 and emergency telephones 20a and 20b for converting voice into a digital state. Consists of Here, the emergency call is installed on the up and down line of the road, respectively, the emergency call installed on the up line or the down line serves as a normal terminal, and the other emergency call is also performed as a base station.

The maintenance computer 15 is preferably provided with a call function for transmitting and receiving data with the outside.

In the figure, 3 is the main switch line card, 4 is the main switch trunk card, 5 is the main switch line card, 6 is the auxiliary switch trunk card, 7 is the digital line card, 10 is the CPU card, 11 is the operating computer, 12 The printer is the printer for the operating computer, the host controller for the self-diagnosis, the line card for the auxiliary switch, 14 the maintenance computer, and the printer for the maintenance computer.

The digital recording device for automatically recording an emergency call of the present invention is a method of recording using a maintenance computer 15 instead of a conventional analog recorder, between the reception desk phone 8 and the maintenance computer 15. After the analog-to-digital converter 17 is connected, the analog voice is converted into a digital voice to automatically record and store the contents of the call of several channels at the same time when the call with the emergency call is made to facilitate the retrieval and movement security of data.

In other words, when picking up the handset of emergency telephones 20a and 20b, such as a highway or a vehicle-only road, the line card of the main exchanger 18 via the optical transmission device 1 in the business office and the optical transmission device 2 in the branch office ( 3) and trunk card (4) connected to the main exchange line card (5) of the main exchanger 18 and through the sub-exchange line card (6) and digital line card (7) of the sub-exchange 19 (8) rings and the operator picks up the handset of the reception desk phone 8 to make a call.

In addition, the call sound according to the call with the emergency call is converted from the analog voice to the digital voice through the analog-to-digital converter 7 and sent to the maintenance computer 15. The maintenance computer 15 automatically detects a call tone and starts recording, and automatically stops at the end of the call.

In addition, the contents of the call can be compressed and stored as a file by the algorithm in the computer, and the file can be decompressed at the time of playback. You can increase the number and record the call content of multiple channels at the same time. On the other hand, since the maintenance computer 15 is provided with a communication function with the outside, only the person authorized by the network can share data in the maintenance computer 15 to quickly cope with an emergency situation.

Here, as an example of a compression method for compressing the call content, if the call contents of two emergency telephones are separately input into one stereo channel, the maintenance computer 15 is separated into each stereo sound by a built-in program. do. The waveform of each channel's conversation is converted from the stereo sound sampled at 44.1KHz to the mono volume of 11.025KHz sampling, and the file size is converted from the 44.1KHz sampling sound to the sample volume of 11.025KHz. Is reduced to 1/4 the size of the normal state. Of course, in normal programs, normal sound does not come out even when played back.

In addition, the conventional analog recorder is difficult to search for the contents of the call and is not easy to move and store.However, unlike the conventional recorder, the emergency call digital recording device searches and reproduces and deletes the data by making the database of the call contents by call time. It is easy and the contents of the call are in a file, so it is easy to move and store the call.

In addition, the conventional analog recorder can record only one call at a time, and it was difficult to play when recording. However, the multi-tasking is supported in the recording method of digitizing the call. Even if the contents are input at the same time, each file can be recorded and saved as well as other call contents can be played during recording.

In particular, by allowing each user to access the program with a password, by combining and modifying the value of the individual character code of each password to generate a unique recognition code to play only by a specific user, the security system is maintained.

Preferably, by providing a communication function with the outside of the maintenance computer 15, it is possible to share the call file contained in each computer in the network environment, and to be able to cope quickly after management and reference collectively centrally.

According to the present invention, by converting the contents of the call with the emergency call to digital and compressed and stored in the maintenance computer, it is possible to obtain the ease of storing the call contents, ease of search, security, etc., and maximize the storage efficiency of the memory. In addition, it can not only record the conversation of several channels at the same time, but also increase the sharing and utilization of the data using the network.

Although the present invention has been described in detail only with respect to the embodiments described, it will be apparent to those skilled in the art that various modifications and changes are possible within the technical idea of the present invention, and such modifications and modifications belong to the appended utility model registration claims. will be.
