DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a remote monitoring device for converting first monitoring information received from a monitoring terminal into second monitoring information and retransmitting the same to the receiving terminal, and a remote monitoring system having the remote monitoring device. is there.

[0002]

2. Description of the Related Art In a remote monitoring system for a building or a house, a monitoring terminal installed at a monitored location detects an abnormality when a sensor connected to the monitoring terminal detects an abnormality such as intrusion of a suspicious person or a fire. Anomaly information to be notified is issued to a remote monitoring device connected by a communication line such as a public telephone line network, and a camera linked with a sensor captures an image of a monitored location and transmits the captured image information. The monitoring center where the remote monitoring device is installed receives monitoring information such as abnormal information and image information from the monitoring terminal, records the monitoring information, and dispatches security personnel to the monitored location where the abnormality has occurred. We are making arrangements.

[0003]

As a method of dispatching security personnel, a monitoring terminal that has detected an abnormality sends abnormality information and location information indicating the location of the building where the abnormality has occurred to a receiving terminal carried by the security personnel. A method in which a remote monitoring device that transmits or receives abnormal information and position information retransmits the abnormal information and position information to a receiving terminal carried by security personnel is disclosed in JP-A-10-23.
1075. However, this method does not transmit image information notifying the current situation of the monitored location.
In addition, software for displaying location information on a map and a large amount of map data are installed in advance on the receiving terminal carried by security personnel, or GPS (Global Posisioning S
ystem) and a receiving terminal connected to it must be deployed, which costs more than the receiving terminal.

When the remote monitoring device attempts to resend the image information received from the monitoring terminal to the receiving terminal in order to give a large amount of information to the security personnel, when the remote monitoring device transmits the image information to the remote monitoring device, If the bandwidth of the communication line connecting the remote monitoring device and the receiving terminal cannot be ensured due to the performance of the equipment, the amount of image information received by the remote monitoring device will take a long time to transfer and the display time will increase. There is a problem. The present invention solves this problem by providing security personnel with a great deal of information about the monitored location so that the security personnel can grasp the status of the monitored location and more quickly arrive at the monitored location. The purpose is to:
