Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a remote monitoring apparatus for managing various equipments in a building from a remote location, and more particularly to a remote monitoring apparatus for collecting operation information of the equipments via a public line.

[0002]

2. Description of the Related Art In a general building, equipment such as an elevator, an air conditioner, a water tank, and a crime prevention machine, which are indispensable for people to safely and comfortably work in the building, are installed. If even one of these various equipments fails, the safety and comfort of the building will be significantly impaired, and in some circumstances people's activities may be virtually impossible. Therefore, in order to prevent such a failure of the equipment from occurring abruptly, it is required to detect a minor malfunction or malfunction at an early stage and take appropriate measures.

A remote monitoring device is known as a conventional technique satisfying the above-mentioned requirements. The remote monitoring device is composed of a monitoring terminal installed in each building to be monitored and an information center that normally monitors a plurality of buildings.
The monitoring terminal keeps recording the operation information of the equipment in the building 24 hours a day. The information center periodically collects the operation information recorded by the monitoring terminals via a predetermined communication line.
For equipments that have been analyzed and found to have malfunctions or malfunctions, prediction of failure occurrence and instructions for appropriate measures will be given, while more detailed cause analysis will be performed for equipments that have recently failed.

In a general remote monitoring device, it is usual to use a public telephone line as the communication line. Therefore, both the building where the monitoring terminal is installed and the information center prepare public telephone lines, and at least the building side notifies the information center side in advance of the telephone number dedicated to access the monitoring terminal. . The information center has a unique information storage means for storing unique information for each monitoring terminal together with this access-dedicated telephone number. The access-destination monitoring terminal for which operation information is to be collected and analyzed has this unique information. It is selected by referring to the storage means. Therefore, the order in which the information center tries to access the monitoring terminals depends on the order in which the unique information of each monitoring terminal is stored in the unique information storage means in the information center.

[0005]

By the way, when a plurality of monitoring terminals are installed in the same building, it is usual to collectively store the unique information group in the unique information storage means in the information center. Is. In this case, the above unique information group is
It is continuously stored in the unique information storage means. Therefore, when trying to collect the operation information of the equipment from a plurality of monitoring terminals installed in the same building, the order in which the information center tries to access is continuous.

On the other hand, it is useless to provide a large number of public telephone lines only for collecting and analyzing operation information. Therefore, even if a plurality of monitoring terminals are installed on the building side, the number of lines is less than the number of installations. Often, only a few public telephone lines, for example, are prepared for access only. On the other hand, the information center side usually prepares a large number of public telephone lines so that the operation information of the equipment can be collected from a large number of monitoring terminals at the same time.

From the above, when the information center attempts to access a plurality of monitoring terminals installed in the same building and having less than the number of allocated public lines, the order is , Will generally be continuous.

However, since it is not possible to access a plurality of parties at the same time on a normal public telephone line, if there are a plurality of monitoring terminals installed in the same building where the above-mentioned conditions overlap, the access procedure from the information center However, there is a problem in that the efficiency of collecting the operation information of the equipment is reduced as well as being complicated. For example, of a plurality of monitoring terminals installed in the same building, immediately after the access to the first monitoring terminal stored in the earliest unique information storage means in the information center is started, An information center having a large number of public telephone lines immediately uses another line to access a second monitoring terminal installed in the same building, which is stored next to the unique information storage means. Try to start. At this time, if only a common telephone line is assigned to all the monitoring terminals including the first one on the building side, the second monitoring terminal cannot be connected to the busy state. . In the above case, the conventional technique repeatedly attempts to access the above busy line from the information center at regular intervals until the collection of the operation information from the first monitoring terminal is completed. As a result, the access procedure is complicated and the efficiency of collecting operation information from each monitoring terminal is reduced.

Therefore, a first object of the present invention is to provide a remote monitoring apparatus capable of accessing each monitoring terminal in an optimum access sequence according to the contents of the unique information storage means in the information center. To do.

A second object of the present invention is to provide a remote monitoring device in which the collection efficiency of operation information from each monitoring terminal device is improved as compared with the conventional one.

A third object of the present invention is to provide a remote monitoring device in which the access procedure for each monitoring terminal is simplified as compared with the conventional one.

In the prior art, when trying to access each monitoring terminal device from the information center 1 in the registration order of each specific information in the specific information file 4, for example, the first monitoring terminal device 201a corresponding to the specific information A1 is accessed. Immediately after starting access to the second monitoring terminal 202a corresponding to the unique information A2, an attempt is immediately made to access the second monitoring terminal 202a. However, a common telephone line is assigned to the monitoring terminals 201a and 202a. Therefore, the access to the second monitoring terminal device 202a always fails, and the telephone line is repeatedly accessed.

Therefore, in the present embodiment, the access order setting means provided in the information center 1 uses the unique information file 4 described above.
During the access to each of a pair of monitoring terminals that are accessed via a common public line in which corresponding unique information is stored before and after, access via a public line different from this common public line The access order is set based on the unique information file 4 so that the other monitored terminals can be accessed.

FIG. 4 is a diagram showing an example of an intermediate file generated by the access order setting means 3 provided in the embodiment of FIG. 1 based on the unique information file of FIG. The three types of intermediate files 5a, 5b, and 5c shown in FIG. 4 include the unique information A1 in the intermediate file 5a and the unique information A2 in the intermediate file 5b for each unique information forming the unique information file 4 described above. , The unique information A3 to the intermediate file 5c, the unique information B1 to the intermediate file 5a,
It is obtained by cyclically allocating the unique information B2-1 to the intermediate file 5b, the unique information B2-2 to the intermediate file 5c, and so on, based on the registration order in the unique information file 4.

FIG. 5 is a diagram showing an example of an access order file generated by the access order setting means 3 provided in the embodiment of FIG. 1 based on the intermediate file of FIG.

It is obtained by connecting a, 5b and 5c.

The access sequence setting means 3 in the processing section 1c of the information center 1 checks the unique information of all the equipment in the unique information file 4 stored in the unique information storage means 1d, and makes a common public. It is confirmed whether or not there is a monitoring terminal device to which a line is assigned, or whether or not there is a monitoring terminal device that monitors a plurality of facility devices. If there is a monitoring terminal device to which a common public line is assigned, the maximum number of monitoring terminal devices sharing the same public line is obtained. Further, when there is a monitoring terminal device that monitors a plurality of equipment devices, the maximum number of the equipment devices connected to the same monitoring terminal device is obtained. For example, when the number of monitoring terminals to which a common public line is assigned is the maximum in the building 2a in FIG. 1 as in the present embodiment, the maximum number of monitoring terminals required by the above is =
It becomes 3. It should be noted that the building 2b in FIG. 1 has a monitoring terminal device that monitors two elevators, but since the number of facility devices connected to the monitoring terminal device is three, the maximum number of facility devices = 3. Become.

After this, the larger value of the maximum number of the monitoring terminals per building and the maximum number of the equipment connected to the monitoring terminals per building, whichever is larger, is determined. Each unique information in the unique information file is allocated to the same number of intermediate files. Alternatively, the communication performed by the communication unit that can be used by the information center 1 always starts asynchronously and ends asynchronously. Therefore, in order to avoid duplication of the communication line for the monitoring terminal device sharing the public line, The maximum number of monitoring terminals per building obtained in accordance with the above, or the maximum number of equipment connected to the monitoring terminals per building, whichever is larger Allocate each unique information in the information file.

Hereinafter, for the maximum number of monitoring terminals per building and the maximum number of equipments connected to the monitoring terminal per building, whichever is larger, the same number of intermediate files A case where each unique information in the unique information file is sequentially allocated will be described.

As described above, the maximum number of monitoring terminals per building in this embodiment = 3, and the maximum number of equipment connected to the monitoring terminals per building = 3. , The number of intermediate files for dividing and outputting each unique information in the unique information file 4 = 3. Therefore, as shown in FIGS. 3 and 4, each unique information in the unique information file 4 is cyclically allocated to the three types of intermediate files 5a, 5b, 5c based on the registration order. After all the unique information is allocated to each of the intermediate files 5a, 5b, 5c, the unique information registered at the end of the intermediate file 5a and the unique information registered at the beginning of the intermediate file 5b are consecutive as described above. The intermediate files 5a and 5b are linked together as described above, and the intermediate file 5c is linked so that the unique information registered at the end of the intermediate file 5b and the unique information registered at the beginning of the intermediate file 5c are continuous. By doing so, the access sequence file 6 shown in FIG. 5 is generated and stored in the unique information storage means 1d. As described above, the monitoring terminal 201 installed from the information center 1 to each of the buildings 2a to 2n shown in FIG.
The access to a, 202a, ..., 201n, 202n is sequentially executed according to the registration order of each unique information in the access order file 6 thus obtained. As a result, corresponding unique information is sequentially stored in the unique information file 4 of the information center 1, and a pair of monitoring terminals accessed via a common public line, for example, a monitor to which the same public line 20a is assigned. During access to each of the combined monitoring terminals such as the terminal 201a (specific information A1) and the monitoring terminal 202a (specific information A2), access is made via a public line different from the common public line (20a). Access to other monitoring terminals will be performed.

It should be noted that the monitoring terminals to which the same public line is assigned are preset with priorities according to a predetermined access order, and in the case of the building 2a in FIG.
For example, it is the monitoring terminal 201a, the monitoring terminal 202a, and the monitoring terminal 203a. Therefore, the monitoring terminal 20 is in the order according to the access order file 6.
When accessing 2a, the incoming call prohibition setting is made in advance for the monitoring terminal device 201a having a higher priority, and then the access to the target monitoring terminal device 202a is started. Similarly, when accessing the monitoring terminal device 203a, the monitoring terminal device 2 having a higher priority is previously in advance.
After making incoming call prohibition settings for 01a and 202a, access to the target monitoring terminal 203a is started.
