一連の動作を行なっていた。In this conventional security terminal device, when transmission to a monitoring center is required, the telephone line is switched to the device side by line switching means, and the telephone line is closed by line opening / closing means to capture the telephone line. After that, a transmission is performed to the monitoring center, and when the transmission is completed, a series of operations are performed such as releasing the telephone line, switching the telephone line to the telephone side, and returning the telephone line to the telephone side.
【０００５】また、監視センターが応答しないなど送信

It is also a long time line, regardless of is閉結(disabled pending shape
State) often occurs. In this case, the exchange forcibly cuts off the current supply to the telephone line, and then intermittently supplies current to the telephone line to check whether the telephone line has been opened.
When it is detected that the telephone line has been opened, the current supply is restarted.

て設定されるようにするとよい。According to the security terminal device of the present invention, when the telephone line is closed by the line opening / closing means to send a signal corresponding to the abnormality detected by the abnormality detecting means to the monitoring center, the telephone is detected by the line current detecting means. The current supply to the line is monitored, and if the current supply cannot be detected by the line current detecting means, the telephone line is opened while the telephone line is switched to the device side, and the opening of the telephone line is detected by the exchange. After the telephone line is opened until a predetermined time set in the control means elapses with reference to the time when the current supply is resumed, the telephone line is closed again. By performing the above control, the exchange restarts the current supply to the telephone line. After confirming that the current supply has been resumed, a signal corresponding to the abnormality detected by the sensor is transmitted to the monitoring center. In the security terminal device of the present invention, it is desirable to further provide an incoming call detecting means for detecting a call signal to the telephone line on the side of the exchange rather than the line switching means. In this case, when the abnormality detecting means detects the abnormality, the control means uses the telephone line because the calling signal is not detected by the incoming call detecting means and the current supply is not detected by the line current detecting means. After confirming that the telephone line has not been switched, the line switching means switches the telephone line to the signal transmitting / receiving means side, the line opening / closing means closes the telephone line on the signal transmitting / receiving means side, and the line current detecting means switches to the telephone line. Monitoring of the current supply from. As a result of monitoring the current supply, if it is confirmed that the current supply is detected by the line current detection means, the control means causes the selection signal transmission means to transmit a selection signal for selecting the monitoring center from the selection signal transmission means to the exchange. After that, the signal transmission / reception means is caused to transmit a signal corresponding to the abnormality detected by the abnormality detection means. On the other hand, when the current supply by the line current detecting means confirms that it is not detected, the control means, line switching hands
Switch the telephone line to the signal transmitting / receiving means side
Further, after the telephone line is opened for a certain period of time by the line opening / closing means, the telephone line is closed and a current supply monitoring operation for monitoring the current supply is performed.
When the current supply is detected, the selection signal is transmitted from the selection signal transmission means to connect the monitoring center to the telephone line, and then the signal transmission / reception means transmits a signal corresponding to the abnormality detected by the abnormality detection means via the telephone line. To do. The fixed time for releasing the telephone line may be set in accordance with the interval at which the exchange monitors the telephone line for on-hook when there is an invalid hold.

記載の警備端末装置。2. The system according to claim 1, further comprising: an incoming call detecting unit provided on the exchange side than the line switching unit and detecting a call signal to the telephone line, wherein the control unit detects that the abnormality detecting unit detects an abnormality. After confirming that the telephone signal is not used because the calling signal is not detected by the incoming detection means and that the current supply is not detected by the line current detection means,
The line switching means switches the telephone line to the signal transmitting / receiving means side, the line opening / closing means closes the telephone line on the signal transmitting / receiving means side, and the line current detecting means switches the telephone line to the telephone line. When the line current detecting means confirms that the current supply has been detected, the selection signal for causing the exchange to select the monitoring center is transmitted from the selection signal transmitting means to the exchange. After sending the signal, the signal transmission / reception means is caused to transmit a signal corresponding to the abnormality detected by the abnormality detection means.On the other hand, if the line current detection means confirms that the current supply is not detected, The line switching means
Therefore, the telephone line is switched to the signal transmitting / receiving means.
