Abstract

PROBLEM TO BE SOLVED: To monitor a system by means of sufficiently following the occurrence of abnormality by cutting connection with a first terminal and taking priority over a monitor job with a second terminal when sensor information of high priority is received from the second monitor terminal while sensor information is received from the first monitor terminal. SOLUTION: In a center-side monitor station 1, priority is previously decided based on a sensor means. When the center-side monitor station 1 receives an emergency button sensor from a monitor terminal 3-n while sensor information informing that a visitor arrives at a police box is received from a monitor terminal 3-1, the priority of the emergency button sensor and that of the visitor sensor are judged. Since the priority of the emergency button sensor is higher than that of the visitor sensor, the center-side monitor a station 1 cuts connection with the monitor terminal 3-1 transmitting visitor sensor information, executes connection with the monitor terminal 3-n transmitting the emergency button sensor and recognizes the situation of the monitor terminal 3-n.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to voice / image communication by receiving sensor information of low priority in a center side monitoring station which receives sensor information, voice and image data information from a plurality of monitoring terminals. The present invention relates to a remote monitoring device that arbitrarily switches to voice / image communication with a monitoring terminal that transmits sensor information with high priority even when receiving sensor information with high priority.

2. Description of the Related Art A conventional monitoring device is disclosed in Japanese Patent Laid-Open No. 7-
As disclosed in Japanese Patent No. 319538, the status monitoring means monitors the status of a plurality of devices constituting the equipment, and the status storage means stores the data representing the abnormal status together with priority information, and the voice message selecting means. It is known that each time a confirmation signal is received, voice message data for abnormal state notification is selected in order from the highest priority stored in the state storage means, and the voice message notification means notifies this as a voice message. There is.

[0003]

As described above, in the conventional monitoring device, when a plurality of devices simultaneously notify an abnormal condition, the next abnormal condition is notified after the message for notifying one abnormal condition is completed. I had to do it.
Therefore, even if priority is decided, once notification of a low-level abnormal message is started, even if an emergency abnormal condition occurs, a high-level message cannot be notified unless one voice message ends. ,
In some cases, it was not possible to carry out monitoring sufficiently following the occurrence of an abnormality.

[0004]

The present invention is to solve these problems, and sensor information, voice and image from a plurality of monitoring terminals installed at a distance via an ISDN network. In a remote monitoring device composed of a center-side monitoring station that receives information such as data and performs monitoring, by giving priority to sensor information, the center-side monitoring station causes the first monitoring terminal to send a sensor with a low priority. When receiving information from the second monitoring terminal and receiving sensor information having a higher priority than this while receiving information and performing monitoring work, the connection of voice and image with the first monitoring terminal is interrupted and the second monitoring is performed. (EN) Provided is a remote monitoring device that prioritizes a voice and image monitoring work with a terminal.

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a block diagram of a remote monitoring apparatus showing an embodiment of the present invention, and FIG. 2 is a flow chart explaining the operation of the remote monitoring apparatus showing an embodiment of the present invention. In FIG. 1, a remote monitoring device of the present invention is a monitoring terminal installed at a remote place for monitoring the situation on the monitoring side, here, 1 to N monitoring terminals 3-1 to 3-N. Say. The center-side monitoring station 1 for managing information from these monitoring terminals, and the monitoring terminal 3-
1, 3-N and the center-side monitoring station 1 are connected by an ISDN line 2, and voice data and image data are transferred via this ISDN line 2. Furthermore, this monitoring terminal 3-
When 1 and 3-N are installed in the police box, a visitor sensor, a call button sensor, an emergency button sensor, a presence / absence button sensor, a public relations guidance button sensor, etc. are installed. It is possible to transfer from the terminals 3-1 and 3-N to the center side monitoring station 1 by using the subaddress of the ISDN line 2 or a packet communication means (not shown). As described above, a plurality of sensor means are provided according to the application, but these sensor means also require treatment according to their urgency. It is different to notify the center-side monitoring station 1 urgently with a sensor for notifying that a visitor has arrived at the police box and an emergency button sensor, and it is necessary to set a priority according to the contents. The operation will be described with reference to FIGS. 1 and 2. When the priority is determined in advance in the center side monitoring station 1 based on the sensor means, the monitoring terminal 3-1 detects that a visitor has arrived as shown in FIG. 2A (step 10). , Center side monitoring station 1
Can be notified (step 11). When the center-side monitoring station 1 receives from the monitoring terminal 3-1 sensor information indicating that a visitor has come to the police box, if an emergency button sensor is received from the monitoring terminal 3-N (step 20), the emergency button The priority of the sensor and the visitor sensor is determined (step 21). Here, the emergency button sensor has a higher priority than the visitor sensor, so
The center-side monitoring station 1 suspends the connection with the monitoring terminal 3-1 transmitting the visitor sensor information (step 22) and connects with the monitoring terminal 3-N transmitting the emergency button sensor ( In step 23), the status of the monitoring terminal 3-N is confirmed.

[0006]

As described above, according to the present invention, the priority is given to the sensor information so that the priority is given to the sensor information even when the voice / image communication is performed by receiving the sensor information from a certain monitoring terminal. If there is a monitoring terminal that is sending highly accurate sensor information, you can immediately make a voice and image communication connection with this monitoring terminal,
Realize accurate and speedy remote monitoring work.
