BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a remote monitoring device, and more particularly to a remote monitoring device for monitoring terminal devices installed in a plurality of buildings via telephone lines.

0002

[Prior Art] Conventional remote monitoring devices include, for example,
As described in Publication No. 9-242260, terminal devices are provided in each of a plurality of buildings where equipment such as air conditioning equipment and elevators are installed, and these terminal devices are provided to service companies etc. via telephone lines. It is now monitored by a central monitoring device.

[0003] The above-mentioned terminal device is electrically connected to the equipment, and when an abnormality occurs in the equipment,
A building code representing a specific building and equipment information representing the status of equipment are transmitted as output signals to the central monitoring device via a telephone line. After receiving this output signal, the central monitoring device temporarily stores the output signal in a reception buffer, and then stores the terminal information including the building code, equipment name, status name, etc., stored in the storage device based on the output signal, and the previous Read the receiving equipment information and compare the equipment information with the previous receiving equipment information. As a result of the comparison, equipment whose status has changed from 0 to 1 is stored in the storage device as having an abnormality, and output means, such as a display device and a printing device, indicate the name of the equipment in which the abnormality has occurred and the name of the abnormal state. , outputs bill code, etc. The monitor in the central monitoring device looks at these displays and contacts the necessary department, and if necessary, service personnel go to the building where the abnormality has occurred to carry out repair work. Equipment whose status has changed from 1 to 0 due to repair is stored in the storage device as having recovered from the abnormal condition, and the name of the recovered device, recovery status name, building code, etc. are displayed on the display device and printing device. is output.

[0004] For example, when installing a new terminal device in a newly constructed building, it is important to check whether this terminal device can correctly detect abnormal signals from the equipment and send output signals to the central monitoring device. It is necessary to check whether the terminal information related to the newly installed terminal device registered in the storage device in the central monitoring device matches the building code, equipment name, etc. For this reason, the test start time, test end time, and building code are registered as test setting information in the central monitoring device, and the test settings of the terminal information are used by the central monitoring device's scheduling function from the test start time to the test end time. Set flag. When the central monitoring device receives the test alarm signal transmitted from the newly installed terminal device, it reads the terminal information from the storage device, compares this terminal information with the test alarm signal, and then records the comparison result. The results are stored in a storage device and printed out using a printing device, and the monitor then contacts the on-site inspector by phone to confirm the results.

[0005]

[Problems to be Solved by the Invention] However, in the above-mentioned conventional remote monitoring device, when a test alarm is issued for the terminal device as described above, the central monitoring device receives a large number of messages from the terminal device in a short period of time. Because of the number of transmissions, it took a considerable amount of time for processing within the central monitoring device. For this reason, even if an output signal is received from another terminal device during a test of the terminal device, the processing of this output signal is delayed, resulting in a problem that there is also a delay in responding to the occurrence of an abnormality. Ta.

The present invention has been made in view of the actual situation in the prior art, and its purpose is to enable the internal processing of the central monitoring device to be carried out in a short time even when a terminal device test notification is issued. Our goal is to provide a remote monitoring device that can
