Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hierarchical information collection / distribution system, and more particularly to a system suitable for collection / distribution of disaster information and the like.

[0002]

2. Description of the Related Art Conventionally, the situation of rivers, coasts, roads, harbors, dams, etc. has been grasped, and disaster prevention and expansion have been prevented.
In order to further support recovery, there is an information collection and distribution system having a hierarchical structure as shown in FIG.

[0003] This conventional information collection / distribution system uses information collected from various information collection devices 61 installed at necessary places such as rivers, coasts, roads, ports, dams, etc., to be grasped, in a predetermined administrative division unit or The data is collected by the intermediate stations 62-1 to 62-n installed in the monitoring section units via a dedicated line or a public line.

[0004] Each of the middle-level stations 62-1 to 62-n performs necessary tally processing and the like, and transmits the data to, for example, an upper-level station 63 installed in each prefecture via a dedicated line or a public line. At 63, the current situation of each area and the situation grasp target, and the expansion or contraction situation of the disaster are predicted.

[0005] Here, if a place where any countermeasure is to be taken is found, necessary instruction information is sent to the middle station which controls the pertinent area and the lower station 64 belonging to the lower order of the middle station. It distributes, and also distributes instructions such as rescue to the middle and lower stations in the adjacent area.

In this case, each of the intermediate stations 62-1 to 62-n
Is installed in an administrative organization such as a civil engineering office, for example.

[0007]

However, in a simple pyramid-type information collection and distribution system as shown in FIG. 10, if a failure occurs in the upper station 63, it covers all areas. Situation can no longer be ascertained, and the situation can only be ascertained on a median station basis. There is a problem that the middle office cannot be contacted.

[0008] Further, if a failure occurs in the leased line or public line connecting the upper station and the middle station, the information collected by the middle station is not transmitted to the upper station. There is a problem that it is not possible to grasp the current situation of a certain area, and it is impossible to predict the expansion or reduction of disasters.

[0009] These problems can be avoided by providing a plurality of lines connecting each middle station and the upper station, one as a normal line and the other as a backup line. However, since it is necessary to secure a backup line even in a normal state where no disaster occurs, there is a problem that the entire facility becomes excessive and the maintenance cost increases, which is not preferable.

[0010] The present invention provides a hierarchical information collection system capable of grasping the overall situation and the situation in an adjacent area with the minimum necessary equipment even when a failure occurs in a line or the like or when a failure occurs in each device. The purpose is to provide a distribution system.

[0011]

In order to achieve the above object, according to the present invention, predetermined information is collected from a plurality of monitored objects, transmitted to a higher-level device via a communication line, and transmitted from a higher-level device. In a hierarchical information collection / distribution system including a plurality of lower devices that receive a processing result of collected information via a communication line, a plurality of lower devices provided in a hierarchy between each lower device and a higher device are represented. A representative device, a first collection / distribution path for directly transmitting / receiving information between each lower-level device and the higher-level device, and collection information of the lower-level device under the control of the representative device and information from the higher-level device collected by the representative device. And a second collection / distribution route for distributing to a lower-level device via a communication device.

According to a second aspect of the present invention, in the first aspect of the present invention, when a processing result from a higher-level device is not received within a predetermined time within the representative device, a lower-level device under the jurisdiction of the representative device. A means for transmitting an unreceived message to the apparatus is provided.

According to a third aspect of the present invention, in the first aspect of the present invention, the representative device has a part of the function of the higher-level device. The function is performed on behalf of.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, an embodiment of a hierarchical information collection and distribution system according to the present invention will be described in detail with reference to the accompanying drawings.

FIG. 1 is a system configuration diagram showing an embodiment of the present invention.

The information collected from various information collecting devices 11 installed at necessary places such as rivers, coasts, roads, ports, dams, etc. to be monitored is transmitted to a central station installed in predetermined administrative divisions or monitoring divisions. At 12-1 to 12-n, the data is collected via a dedicated line or a public line, and each of the intermediate stations 12-1 to 12-n is collected.
n to perform necessary tallying processing and the like, and transmit the result to a higher-level station 13 installed in, for example, a prefectural or national unit via a dedicated line or a public line.

Then, the upper station 13 predicts the current situation of each area and the situation to be grasped, and the situation of expansion or contraction of disasters. If a place where any countermeasure is to be taken is found, the corresponding area is identified. Necessary instruction information is distributed to the middle office under the jurisdiction and the lower office 15 belonging to the lower office.

Furthermore, instructions are provided to deliver instructions such as rescue to the middle and lower stations in the adjacent area, and furthermore, representative middle stations 14-1 to 14-1 representing a plurality of middle stations.
4-m (m <n) are installed, and each middle station 12-1 to 12-12
-N and the upper-level station 13 directly transmit and receive disaster information and the like via the first collection / distribution route a, and
-1 to 14-m collect the collected information of the middle stations under the jurisdiction and the information from the upper station 13 as representative middle stations 14-1 to 14-m.
Are collected and distributed to the middle-level station via a second collection and distribution route b passing through.

In this case, each of the intermediate stations 12-1 to 12-n

12-n is set for each prefecture, and the subordinate station 15 is set for each administrative organization such as a civil engineering office.

Incidentally, the hierarchical information collection and distribution system of this embodiment differs from the conventional configuration in that the representative middle station is 14-
It is characterized in that a second collection and delivery route b via 1 to 14-m is provided. In this case, each of the intermediate stations 12-1 to 12-n
Is transmitted in parallel to both the first collection and distribution route a and the second collection and distribution route b. Similarly, the information distributed from the upper station 13 is the first collection and distribution route a and the second collection and distribution route a. The data is distributed in parallel to both collection and distribution routes b.

Like the upper station 13, the representative middle stations 14-1 to 14-m have a function of summarizing the information of the monitoring targets collected by the middle stations under their control, and expanding the disaster based on the sum result. Alternatively, it has a part of the function of the upper station 13 such as a function of predicting reduction and a function of transmitting the tally result to a middle station under its jurisdiction at predetermined time intervals.

FIG. 2 is a block diagram showing a schematic configuration of the middle station 12-n (or representative middle station 14-m) and the upper station (or representative middle station) 13. In FIG. 2, a middle station 12-n (or a representative middle station 14-m) includes an information collection and distribution device 121 that sequentially stores various types of disaster information collected by the information collection device 11 in a disaster information database 122, and an operator. And a router 1 for transmitting and receiving information between the information display terminal 123 and a higher-level station 13 via a communication line.

Further, the upper station 13 stores disaster information and the like received from the middle station 12-n (or the representative middle station) via the router 135 in the disaster information database 132 according to the monitoring target area and sequentially stores them. At the same time, an information collection / distribution device 131 that periodically or irregularly distributes various instructions and information on the aggregation result to the intermediate station (or representative intermediate station) 12-n at predetermined time intervals, and all the intermediate stations An information processing device 133 that performs a tallying process on collected monitoring target information and stores a tallying result.
And an information display terminal 134 for displaying on the screen the disaster status and the like in the area designated according to the instruction from the operator.

FIG. 3A shows the middle station 12-1 and the upper station 1
FIG. 7 is an explanatory diagram showing a backup system in the case where a failure has occurred in a first collection and delivery route a connecting to No. 3;

As shown by the broken line, when a failure occurs in the first collection / distribution path a connecting the middle station 12-1 and the higher station 13, the information collected by the middle station 12-1 is representative. Station 1
The information is aggregated with the information of the middle station 12-2 under the same jurisdiction and transmitted to the upper station 13 via the second collection / distribution route b via 4-1.

The upper station 13 with respect to the middle station 12-1
Is distributed to the middle station 12-1 via the second centralized distribution path b via the representative middle station 14-1.

Therefore, in the upper station 13, the middle station 12
Therefore, even if a failure occurs in the direct line between the central station 12-1 and the central station 12, the information collected by the intermediate station 12-1 can be reliably received, and the disaster situation in the area can be grasped.

FIG. 3B is an explanatory diagram showing a backup system in the case where a failure has occurred in the second collection / distribution path b connecting the representative middle station 14-1 and the upper station 13.

As shown by the broken line, the representative middle station 14-
In the event that a failure has occurred in the first collection / distribution route a connecting between the central station 1 and the upper station 13, the information collected by the representative middle station 14-1 is transferred to the first collection / delivery via one middle station 12-1. The information is aggregated with the information of the middle station 12-1 and transmitted to the upper station 13 via the route a. Also, the upper station 1 with respect to the representative middle station 14-1
3 is distributed to the representative middle station 14-1 via the middle station 12-1.

Therefore, even when a fault occurs in the line with the representative middle station 14-1, the upper station 13 reliably receives the information collected by the representative middle station 14-1. It is possible to grasp the disaster situation of the whole area.

Also, even if any failure or failure occurs in the representative middle station 14-1 itself, the upper station 13 is controlled by the middle station 12-1, 12-12 under the control of the representative middle station 14-1.
It is possible to aggregate the disaster information of No. 2 and distribute the situation in the adjacent area.

FIG. 3C shows a second collection / distribution route b connecting the representative middle station 14-1 and the upper station 13, and the middle station 12-1.
FIG. 9 is an explanatory diagram showing a backup system in the case where a failure has occurred in both of the first collection and delivery route a connecting the network and the upper station 13.

As shown by the broken line, the representative middle station 14-
When a fault occurs in both the second concentrating and distributing path b connecting the first station and the upper station 13 and the first concentrating and distributing path a connecting the middle station 12-1 and the higher station 13, the middle station 12 -1 and the information collected by the representative middle station 14-1 are transmitted to the upper station 13 via the first collection / distribution route a via the other middle station 12-2. Also, instruction information and the like from the upper station 13 to the representative middle station 14-1 and the middle station 12-1 are distributed via the middle station 12-2.

Therefore, even if a failure occurs in the line between the representative middle station 14-1 and the middle station 12-1, the upper middle station 13 will not be able to operate the representative middle station 14-1 and the middle station 14-1. Bureau 12
-1 can surely receive the collected information and grasp the disaster situation of the whole area.

Also, even if any failure or failure occurs in the higher-level station 13 itself, the representative middle-level station 14-1 checks the status of the neighboring area with the middle-level stations 12-1 and 12-2 under its jurisdiction. Can be delivered.

FIG. 4 shows a case where a failure has occurred in the information collecting and distributing device 121 inside the middle station and the representative middle station, and reference is made to information such as a disaster situation in an area under the jurisdiction of the middle station and the representative middle station. It is explanatory drawing which shows the backup system in the case where it becomes impossible.

When a failure occurs in the information collection and distribution device 121 and the information display terminal 123 is operable, the disaster information collected by the upper station 13 is referred to by a route indicated by a thick solid line, and the entire area or the adjacent area is referred to. You can grasp the disaster situation in the area.

Similarly, in FIG. 5, a failure occurs in the information collecting and distributing device 131 and the information processing device 133 in the upper station 13, and it becomes impossible to refer to information such as a disaster situation in an area under the jurisdiction of the upper station 13. If the information display terminal 134 is operable, the disaster information collected by the middle station (or representative middle station) 12-1 along the route indicated by the thick solid line in FIG. You can grasp the disaster situation at the unit or the representative middle station.

Therefore, according to the above configuration, even if a failure occurs in a line or the like, the overall situation and the situation in an adjacent area can be grasped with the minimum necessary facilities.

By the way, in the above configuration, the upper station 13 or the representative middle stations 14-1 to 14-m collects information collected from the representative middle station and the middle station under the jurisdiction, or the lower station, and totals the information. It has a function to periodically transmit the result, but if any trouble occurs in the upper station itself or the representative middle station itself, the representative middle station and the middle station under its jurisdiction, or the lower station, It is not possible to grasp the processing result from the host.

In such a case, the representative middle station and the middle station under the jurisdiction, or the person in charge of the lower station need to make an inquiry to the upper level each time, and the burden on the person in charge increases. In particular, the occurrence of such a burden at the time of the occurrence of a disaster undesirably hinders other communication work.

Therefore, a process as shown in FIG. 6 is added to the representative middle station or the middle station. In other words, when it is in a state of waiting for reception from an upper station (step 601), it is determined whether or not a processing result from an upper station of the own station is received within a predetermined time interval (step 602). If not, a retransmission request for the latest totaling result is transmitted to the higher order (the upper intermediate station for the representative middle station, the upper intermediate station for the middle station) (step 603).

If there is no response from the higher order despite the retransmission request (step 604), a non-received message is created (step 605), and then a filing process is performed (step 606). A display request is sent to the display terminal of the station for display (step 607), and is transmitted to a lower station under the jurisdiction (a middle station if the representative middle station, a lower station if the middle station) (step 607). 6
08).

However, if the latest total result can be received in response to the retransmission request, or if the latest total result has been received within a predetermined time interval, the retransmission request is not made and the process immediately proceeds to the filing process. .

In the lower station receiving the unreceived message,
As shown in FIG. 7, in the reception waiting state (step 70).
1) If the latest total result or unreceived message is received from the host, filing processing of the received information is performed (step 702), and a display request is sent to the display terminal of the own station to be displayed (step 703). .

When the received message is the latest counting result, for example, a display terminal screen 801 as shown in FIG.
Is displayed in the information display area 802, and a message 804 indicating “regular reception is normal” is displayed in the reception state display area 803.

However, when the received message is an unreceived message, for example, nothing is displayed in the information display area 802 of the display terminal screen 801 as shown in FIG. Has not been received. "

In the case where information such as the result of the aggregation, which is periodically transmitted from the upper station of the own station, cannot be received within a predetermined time interval, an unreceived message is transmitted to the lower station under the jurisdiction. By displaying the information, it is not necessary for a lower station to perform an inquiry operation by a person in charge of a higher order, and the burden on the person in charge is reduced.

[0049]

As described above, according to the present invention, even when a failure occurs in a line or the like or when a failure occurs in each device, the entire situation and the situation in an adjacent area can be grasped with the minimum necessary facilities. can do.

When the information such as the result of the summation periodically transmitted from the upper station of the own station cannot be received within a predetermined time interval, the unreceived message is transmitted to the lower station under the jurisdiction to be displayed. As a result, there is no need to perform inquiries by the person in charge of the higher order in the lower station,
The burden on the person in charge can be reduced.
