Description

The present invention relates to an emergency call device that makes an emergency call to an emergency call receiving organization such as a police station, a fire station, or the Japan Coast Guard.

An emergency call device that calls the special number (110, 119, 118), which is the telephone number of the reception system (hereinafter referred to as the command stand) of emergency call reception organizations such as police stations, fire departments, and maritime security agencies. In, when an emergency call factor such as a traffic accident or a fire occurs, the telephone line is captured and an emergency call is made.

For example, in the case of a fire reporting device, when a fire reporting factor occurs, a call is made to 119, which is the telephone number of the fire command stand, and after the fire command stand responds, a built-in voice message is transmitted, and after transmission, a telephone line is sent. To disconnect. After that, it waits for a reverse call (call back) from the fire command stand for a certain period of time, and when there is a reverse call, it answers and talks with the dedicated telephone connected to the fire alarm device, and disconnects the line after the call ends. do.

By the way, in the case of an emergency call to the command stand, response notification and end-of-call notification are not performed by reversing the polarity of the line from the command stand (see Patent Document 1). For this reason, the fire alarm device responds (calls) to the reverse communication with a dedicated telephone, so it waits for an incoming call from the command stand for a certain period of time after the line is disconnected, and when there is no incoming call for a certain period of time, the command stand answers. Judge that it is not.

FIG. 1 is a diagram showing a configuration of an emergency call system including an emergency call device according to an embodiment of the present invention. In this figure, the same parts as those in FIG. 5 are designated by the same reference numerals as those in FIG.

This emergency call system is provided by an emergency call device 1 that calls an analog telephone line of a telephone network 4 to make an emergency call to a command stand 5, an emergency call dedicated telephone 2 and a general telephone 3 connected to the emergency call device 1. Become. The telephone network 4 is a PSTN, and the analog telephone line is a line for which a caller ID notification service (number display service) is contracted. The emergency call dedicated telephone 2 and the general telephone 3 share a telephone line.

The command stand 5 is a reception system of a police station, a fire station, or the Japan Coast Guard, and the special numbers, which are telephone numbers, are 110, 119, and 118, respectively. The emergency call device 1 has a function of calling 110, 119, or 118 to make a call.

The emergency call dedicated telephone 2 is a dedicated telephone for making a call with the command stand 5. The general telephone 3 is a telephone (including a business phone, a facsimile machine, etc.) that can be used while the emergency call device 1 is on standby. The general telephone 3 can also make a call to the command stand 5 to make a call.

The emergency call device 1 includes a line control unit 11, an emergency call dedicated telephone call route control unit 12, a general telephone call route control unit 13, and a control unit 14 that controls each of these units.

The line control unit 11 is connected to the subscriber line of the telephone network 4, and performs connection control with the telephone network 4, incoming call detection, dial signal transmission, and the like. The emergency call dedicated telephone call route control unit 12 controls the call route between the emergency call dedicated telephone 2 and the line control unit 11. The general telephone call route control unit 13 controls the call route between the general telephone 3 and the line control unit 11.

Let the emergency call device 1 execute FIGS. 3 and 4). Further, the control unit 14 functions as an incoming call signal determination means and an incoming call display control means according to the present invention.

<Operation of the emergency call device while waiting for reverse communication>
The emergency call device 1 makes a call to the command stand 5, and after the response of the command stand 5, transmits a built-in voice message, and after the transmission, disconnects the telephone line. After that, it waits for a reverse communication from the command stand 5 for a certain period of time. FIG. 2 is a flowchart showing the operation of the emergency call device 1 when an incoming call is detected while waiting for reverse communication. This flow is executed by the control unit 14 in response to the incoming call detection by the line control unit 11.

The control unit 14 analyzes the incoming signal (step ST1) and determines whether or not it is an IR signal (step ST2). Here, the IR signal is a normal ringing signal, and the telephone usually rings when it receives it. If it is determined to be an IR signal (step ST2: Yes), the emergency call dedicated telephone call route control unit 12 is controlled to ring the emergency call dedicated telephone 2 (step ST3), and then, as shown in this figure. End the flow that has been done. Here, depending on the setting, both the emergency call dedicated telephone 2 and the general telephone 3 can be ringed in step ST3.

If it is determined that it is not an IR signal (step ST2: No), it is determined whether it is a CAR signal (step ST4). Here, the CAR signal is an information terminal activation signal (number display incoming signal) sent before the caller's telephone number is notified by the caller's telephone number notification service, and when the telephone receives this signal. Capture the line and receive the caller's phone number. If it is determined that the signal is a CAR signal (step ST4: Yes), the general telephone call route control unit 13 is controlled to ring the general telephone 3 (step ST5), and then the flow shown in this figure is shown. To end. When it is determined that the signal is not a CAR signal (step ST4: No), that is, when the incoming signal is neither an IR signal nor a CAR signal, the flow shown in this figure is terminated as it is.

<Operation when there is reverse communication while waiting for reverse communication>
FIG. 3 is a sequence diagram showing an example of the operation of the emergency call device according to the embodiment of the present invention. This operation is an example when there is a reverse communication while waiting for a reverse communication.

The emergency call device 1 dials a special number when a report factor (in the case of a fire report device, a fire occurs) occurs (procedure S1). That is, a special dial signal is transmitted to the telephone network 4. The telephone network 4 that has detected the special number transmits an incoming signal to the command stand 5 (procedure S2). When the command stand 5 responds (procedure S3), the telephone network 4 transmits a response to the emergency call device 1 (procedure S4). The emergency call device 1 transmits a message (procedure S5), and after transmission, disconnects the line (procedures S6 and S7). The emergency call device 1 waits for a reverse communication from the command stand 5 for a certain period of time after the line is disconnected.

The command stand 5 performs reverse communication to the telephone network 4 (procedure S8), and the telephone network 4 transmits an IR signal as an incoming signal to the emergency call device 1 (procedure S9). Since the incoming call signal is an IR signal, the emergency call device 1 rings the emergency call dedicated telephone 2 (procedure S10). By the off-hook of the emergency call dedicated telephone 2, the response is notified to the command stand 5 via the emergency call device 1 and the telephone network 4 (procedures S11 to S13), and a reverse communication call is made with the command stand 5 (procedure S14). ). After that, when the reverse communication call ends, the line is disconnected from the emergency call dedicated telephone 2 (procedures S15 to S17). The reverse communication operation of the above procedures S8 to S17 is repeated until the command stand 5 disconnects the line.

The emergency call device 1 waits for a reverse communication from the command stand 5 for a certain period of time after the line is disconnected. The command stand 5 performs reverse communication to the telephone network 4 while the emergency call device 1 is waiting for reverse communication (procedure S18), and the telephone network 4 transmits an IR signal as an incoming signal to the emergency call device 1 (procedure S18). Procedure S19). Since the incoming call signal is an IR signal, the emergency call device 1 rings the emergency call dedicated telephone 2 (procedure S20). After that, the same procedure as the above-mentioned procedures S11 to S17 is executed.

<Operation when there is a general incoming call while waiting for reverse communication>
