BACKGROUND OF THE INVENTION
The present invention relates to a traffic collection system that allows a traffic collector to freely select and acquire a plurality of pieces of traffic information desired to be acquired from each terminal, and more specifically, each of a plurality of maintenance systems. The present invention relates to a traffic collection system that collects traffic elements each measured by a plurality of data measuring devices in response to a traffic collection request issued by a traffic collector, and edits the collected traffic elements to generate traffic data.
[0002]
[Prior art]
A conventional traffic collection system will be described with reference to FIG. In FIG. 2, when a traffic collector issues a traffic collection start notification including a traffic item (fixed), a measurement cycle, and the number of measurements from the input device 12 in the maintenance system 11, the traffic collection start notification is communicated from the input device 12. It is transmitted to the receiving device 22 of the device 21. When receiving the traffic collection activation notification, the reception device 22 supplies this notification to the collection device 23. The collection device 23 makes a traffic collection request to each of the plurality of data measurement / editing devices 24, 25, and 26 in order to collect a predetermined traffic item based on the received traffic collection start notification.
[0003]
That is, when the collection device 23 is instructed about the measurement cycle and the number of measurements based on the received traffic collection start notification, the collection device 23 issues a traffic collection request instruction 1 to each of the plurality of data measurement / editing devices 24, 25, 26. Issue a traffic collection request to each data measurement / editing device.
[0004]
A plurality of data measuring / editing devices 24, 25, and 26 accumulate the traffic collected for each measurement period, extract the difference of the traffic collected for each period, and edit the traffic generated during the measurement period. To do. The traffic generated during each measurement cycle is returned to the collection device 23 from each of the plurality of data measurement / editing devices 24, 25, 26. The collection device 23 activates a transmission device 27 to transmit a signal to the maintenance system 11 and transmits traffic data from the transmission device 27 to the output device 13 of the maintenance system 11.
[0005]
Next, a case where a plurality of traffic collection activation notifications are generated at the same time and request instructions 1, 2, and 3 are issued will be described. Specifically, for example, the request instruction 1 requests traffic collection of 10 times at a measurement cycle of 2 minutes, and the request instruction 2 requests traffic collection of 12 times at a measurement cycle of 10 minutes. Yes, it is assumed that the request instruction 3 requests 24 times of traffic collection at a measurement period of 60 minutes.

When the request instruction 1 is generated, the request instruction 1 is notified from the input device 12 of the maintenance system 11 to the receiving device 22, and further notified from the receiving device 22 to the collecting device 23. In order to collect the traffic, the collection device 23 notifies the plurality of data measurement / editing devices 24, 25, and 26 of the request instruction 1 to perform traffic measurement notification.
[0007]
When receiving the request instruction 1, the plurality of data measuring / editing devices 24, 25, and 26 start traffic measurement and secure a storage area for accumulating collected data for 10 times. Data collected at 2-minute intervals is accumulated in this storage area. Further, when the collected data is accumulated in the storage area, each of the data measuring / editing devices 24, 25, and 26 calculates the difference between the data collected in the previous cycle (2 minutes before) and the data collected in the current cycle. This calculated difference data is traffic (for example, the number of signals) generated in 2 minutes. This process is performed by each of the plurality of data measuring / editing devices 24, 25, and 26, and traffic data is collected for each traffic item type and returned to the collecting device 23. The collection device 23 transmits the traffic data to the output device 13 of the maintenance system 11 via the transmission device 27 and notifies the maintenance system 11 of the traffic data.
[0008]
When the request instructions 2 and 3 occur simultaneously in parallel with the request instruction 1 described above, the plurality of data measuring / editing devices 24, 25, and 26 receive the respective request instructions and measure the request instruction 1. A process of securing a storage area for 10 times, a storage area for 12 times of measurement of request instruction 2, and a storage area for 24 times of measurement of request instruction 3 and collecting traffic at each measurement cycle It will be done in parallel.
[0009]
[Problems to be solved by the invention]
The above-described conventional traffic collection system is a method of collecting traffic data periodically, and accumulates all information in the storage area and collects information determined in advance by the system from the maintenance system. There is a time lag between the traffic data when the user wants the traffic data and the traffic data actually received by the user, and it is difficult to always obtain the current traffic data.
