Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a security terminal device.

[0002]

2. Description of the Related Art In recent years, security terminals are often provided on buildings such as buildings in order to quickly detect abnormalities in facilities such as fire and intrusion and minimize damage.

[0003] As shown in FIG. 3, such a security terminal device 1 has a sensor 2 for detecting an abnormality in the facility such as a fire or an intrusion, and also has a security center via a communication line 3. When the sensor 2 detects an abnormality, it notifies the security center 4 immediately.

[0004] A technique relating to the operation check of the sensor in the security terminal device is described in Japanese Patent Application Laid-Open No. 6-84085. FIG. 4 is a diagram described in the above publication, in which the security terminal device 10 includes a sensor 11, a sensor operation detection unit 12, and a signal transmission unit 13, and is not illustrated via a communication line 14. Connected to a security center. With this configuration, when the sensor 11 detects an abnormality, the sensor 11 is in an open state as indicated by an arrow A in the figure. When the sensor operation detecting unit 12 detects this abnormality, an abnormal signal is issued, and the abnormal signal is reported to the security center via the signal transmitting unit 13 and the communication line 14.

The security terminal device 10 further includes a pseudo abnormal signal control unit 15, a relay 16, a relay contact 16a, and an abnormal signal detection test unit 17. Pseudo abnormal signal control unit 1
5 transmits a pseudo abnormal signal to the relay 16 and the abnormal signal detection test unit 17 at predetermined intervals. Relay 16
Receives the pseudo-abnormal signal, the contact 16a is opened as shown by the arrow B in the drawing, and the same circuit state as when the sensor 11 detects the abnormality is created.

With this configuration, an abnormal signal detection test section 1
7 receives the pseudo-abnormal signal from the pseudo-abnormal signal control unit 15 and checks whether or not the sensor operation detecting unit 12 detects the opening of the contact 16a. In this case, when circuit open is detected in response to the pseudo abnormal signal, it is confirmed that the operation is normal. At the time of a malfunction, a malfunction signal is sent from the signal sending unit 13.

[0007]

However, the conventional security terminal device 10 has a problem that the operation can be checked only in an online state connected to the security center via the communication line 14. Therefore, for example, when the security terminal device 10 is installed, if it is desired to check the operation of the sensor, the operation cannot be performed only by the contractor. Connection state (online state).

The present invention has been made in view of the above circumstances, and has as its object to provide a security terminal device capable of checking the operation of a sensor even when it is offline.

[0009]

According to a first aspect of the present invention, there is provided a security terminal device, wherein a sensor for detecting an abnormality in the equipment, a sensor operation display section for displaying an operation state of the sensor, and a communication line. A security terminal device having an online operation management unit for displaying the operation status of the sensor on the sensor operation display unit when online, which is connected to the security center via the security terminal, wherein the security terminal device is connected to the security center. Offline when you are not connected to
An off-line operation management unit for displaying the operation status of the sensor on the sensor operation display unit, and a sensor operation display key for driving the off-line operation management unit are provided. In the security terminal device according to claim 2,
2. The security terminal device according to claim 1, wherein the sensor operation display key is configured to be able to drive the online operation management unit when online.

According to the first aspect of the present invention, when the sensor operation display key is depressed during offline operation, the offline operation management unit is driven, and the sensor operation display unit displays the operation status of the sensor. That is, the operation check of the sensor is achieved even when the device is offline. According to the second aspect of the present invention, the operation check of the sensor is achieved by pressing the sensor operation display key both online and offline. That is, the sensor operation can be checked by the same operation both online and offline, and the operability is good.
