The present invention relates to a data processing device, a data processing method, and a program.

For example, in an air traffic control system, as for aircraft position information, it is necessary for the air traffic controller to grasp the latest information, and there is a demand for accumulating as much historical information as historical information for future use. In a system that stores data with such characteristics in a database, if a large amount of data occurs in a short time or if the system is in a degraded state due to a failure, etc., the writing process to the database will not catch up with the reference. The data may be out of date. As a result, for example, the controller may not be able to refer to the latest flight data (aircraft position information). In order to be able to always refer to the latest information and history information, it is necessary to configure a large-scale system from the viewpoint of ensuring performance and redundancy, which increases the cost.

In Patent Document 1, in order to avoid the above problem, in a device that controls the order of writing to a database by a queue, when the system is under heavy load, data is fetched from the end of the queue and written to the database, so that the latest information is constantly updated. Techniques for making reference available are described.

Japanese Patent Application Laid-Open No. 2004-242242 describes a technology that controls registration in a queue that receives a control message when a congestion state is detected in a system that performs congestion control that effectively controls congestion of a service network. Has been done.
In Patent Document 3, the pending elapsed time from the start of individual pending transactions of a transaction held in a queue of a transaction processing device is monitored, and an event occurs when the transaction reaches a preset pending limit time. A technique for notifying a terminal device of a transaction and suppressing the transaction is described.

Hereinafter, a data processing device, a data processing method, and a program according to an embodiment of the present invention will be described with reference to the drawings.

FIG. 1 is a diagram showing a configuration of a data processing device according to the present embodiment.
The data processing device 100 is a device that writes the data received from the plurality of sensor units 200 into a database and outputs the data stored in the database so that the operator US can refer to the data.

The sensor unit 200 includes a sensor, a storage unit that stores a sensor ID (IDentification) of its own device, and a transmission unit that adds the sensor ID to sensor data sensed (detected) by the sensor and transmits the sensor data to the data processing device 100. Prepare Sensing is measuring, detecting, or collecting. The sensor ID is identification information that identifies each sensor unit 200. In the present embodiment, a case will be described as an example where the sensor unit 200 includes a radar mounted on each aircraft, a GPS (Global Positioning System), and the like. The sensor data in the present embodiment includes position information of the aircraft and an occurrence time when the position information is sensed. The position information includes latitude, longitude, and altitude.

The data processing device 100 includes a data receiving unit 11, a database writing control device 12, a data writing unit 13, a storage device 14, a data reading unit 15, and a data output control unit 16.

The data receiving unit 11 receives sensor data from each sensor unit 200 and outputs a write request including the received sensor data to the database write control device 12.

The database writing control device 12 controls the writing order of the sensor data received by the data receiving unit 11 to the database by a queue. The database write control device 12 includes a load status detection unit 121, a data write determination information storage unit 122, a data write determination unit 123, a queue registration unit 124, a queue storage unit 125, and a queue extraction unit 126. , Is provided.

The load status detection unit 121 detects the load status of the system at predetermined time intervals. The system load status is, for example, the load on the data processing device 100. For example, the load status detection unit 121 detects, as the load status, the retention rate of the queue stored in the queue storage unit 125 and the usage rate of the CPU (Central Processing Unit). The load status detection unit 121 may also detect, as the load status, the usage status of an I/O (Input/Output) resource, an instruction input by a command operation of the system user, and the like. The load condition detection material can be set by the system user according to the system characteristics. The load status detection unit 121 rewrites and updates the data write determination information stored in the data write determination information storage unit 122 based on the detected load status.

The data write determination information storage unit 122 stores data write determination information which is a standard for the data write determination unit 123 to determine whether or not to write data and which is a standard for specifying data to be written. .. The data write determination information stores the time management table for determination indicating the time of occurrence of the sensor data previously written in the queue, and the time interval for writing the sensor data during high load according to each distance from each of multiple points. There is an important base coordinate management table and a system load status management table showing the load status of the system.

The data write determination unit 123 determines whether to write the acquired sensor data in the database based on the data write determination information stored in the data write determination information storage unit 122. The acquired sensor data is the sensor data included in the write request input from the data receiving unit 11. For example, when the load on the data processing device 100 detected by the load status detection unit 121 is equal to or higher than a predetermined threshold, the data writing determination unit 123 queues the sensor data for each sensor ID according to the data writing determination information. Is determined. That is, when the detected load is equal to or higher than the predetermined threshold value, the data writing determination unit 123 queues the data when the time interval indicated by the data writing determination information has elapsed from the generation time of the previously written data. It is determined that the sensor data to be written is written. At this time, the data write determination unit 123 determines whether or not to write the sensor data in the queue, based on the minimum value of the time intervals corresponding to the position information indicated by the sensor data and the distances between the points. If the data write determination unit 123 determines to write the sensor data, it outputs a write request to the queue registration unit 124. On the other hand, when the data writing determination unit 123 determines that the sensor data is not written, the data writing determination unit 123 discards the sensor data.

When the write request is input from the data write determination unit 123, the queue registration unit 124, of the queues stored in the queue storage unit 125, the queue corresponding to the sensor ID indicated by the sensor data included in the write request. Add the sensor data by writing it at the end of. Then, the queue registration unit 124 outputs a retrieval request including the sensor ID of the added sensor data to the queue retrieval unit 126.
The queue storage unit 125 is a storage area for temporarily storing sensor data by a queue that exists for each sensor ID.

When the retrieval request is input from the queue registration unit 124, the queue retrieval unit 126 retrieves one sensor data from the head of the queue corresponding to the sensor ID included in the retrieval request. Then, the queue extraction unit 126 outputs a data write request including the extracted sensor data to the data writing unit 13.

When the data writing request is input from the queue extracting unit 126, the data writing unit 13 writes the sensor data included in the data writing request into the database stored in the storage device 14. After that, the data writing unit 13 outputs a reading request including the sensor ID of the written sensor data to the data reading unit 15.
The storage device 14 stores a database that stores sensor data for each sensor ID.

When the reading request is input from the data writing unit 13, the data reading unit 15 reads the sensor data of the sensor ID included in the reading request from the database stored in the storage device 14. Then, the data reading unit 15 outputs the read sensor data to the data output control unit 16.

The data output control unit 16 executes the data reference program using the input sensor data, and generates display data to be displayed on the display 300. Then, the data output control unit 16 outputs the generated display data to the display 300. The data reference program is a program that processes sensor data and generates display data to be displayed on the display 300. The display data is, for example, data for displaying a graph or a track map.

The display 300 is a display device that displays the display data input from the data output control unit 16. The operator US can refer to the information displayed on the display 300 to confirm the movement route of the aircraft based on the sensor data.

FIG. 2 is a schematic diagram showing an example of the sensor data according to the present embodiment.
As shown in the figure, the sensor data includes a sensor ID, coordinate data, and an occurrence time. The coordinate data is position information indicating latitude, longitude, and altitude. The occurrence time is the time when the position information is sensed.

FIG. 3 is a schematic diagram showing a data configuration and a data example of the determination time management table according to the present embodiment.
As illustrated, the determination time management table is a table that stores the sensor ID and the last processed data generation time in association with each other. The last processed data generation time is the generation time of the sensor data written in the queue last time.

FIG. 4 is a schematic diagram showing the data structure and data example of the important base coordinate management table according to this embodiment.
As shown in the figure, the important base coordinate management table is a table that stores position information and writing time intervals in association with each other. The position information includes a spot name and coordinates. The spot name is the name of the spot. The point is, for example, an important base or the like. The coordinates are position information indicating the latitude, longitude, and altitude of the corresponding point with coordinate data. The writing time interval is a time interval for writing the sensor data at the time of high load according to each distance to the corresponding point. In the example shown in the figure, the writing time intervals are set so that the distance to the point is within 10 km, within 50 km, within 100 km, and outside 100 km.

The important base coordinate management table allows the system user to set the writing time interval for each point according to the distance to the point. For example, the writing time interval can be set shorter at an important point, and the writing time interval can be set longer at an unimportant point. As a result, it becomes possible to write in the queue more frequently at important bases, and to write to the queue at a certain time interval at points that are not so important.

In the illustrated example, at the point C, the write time interval is 60 seconds within the 10 km range, 120 seconds within the 50 km range, 300 seconds within the 100 km range, and 300 seconds outside the 100 km range. At airport B, which is more important than point C, the write time interval is 30 seconds within 10 km, 60 seconds within 50 km, 120 seconds within 100 km, and 300 seconds outside 100 km, which is shorter than point C. At airports A and F, which are important bases, the writing time intervals are 10 seconds within 10 km, 30 seconds within 50 km, 60 seconds within 100 km, and 120 seconds outside 100 km. short.

FIG. 5 is a schematic diagram showing the data structure and data example of the system load status management table according to the present embodiment.
As shown in the figure, the system load status management table includes a queue retention rate, a CPU utilization rate, a retention rate threshold value, and a utilization rate threshold value. The queue retention rate is the retention rate of the queue detected by the load status detection unit 121. The CPU usage rate is the CPU usage rate detected by the load status detection unit 121. The retention rate threshold value is a threshold value of the queue retention rate that is determined to be high load. The usage rate threshold is a threshold value of the CPU usage rate that is determined to be high load. The retention rate threshold value and the usage rate threshold value can be set by the system user. In the illustrated example, the queue retention rate is 80%, which is greater than the retention rate threshold of 70%. The CPU usage rate is 78%, which is larger than the usage rate threshold value of 70%. Therefore, in this example, the data write determination unit 123 determines that the system load situation is high.

FIG. 6 is a schematic diagram showing an example of the data structure of the queue according to the present embodiment.
As shown in the figure, the queue storage unit 125 stores a pair of queue control information 410 and queue 420 for each sensor ID. The queue control information 410 includes a sensor ID 411 and a head position pointer 412. The head position pointer 412 is a pointer that points to the head sensor data 421-1 to be retrieved by the corresponding queue 420. The head position pointer 412 is updated as the sensor data is added by the queue registration unit 124 and the sensor data is fetched by the queue fetch unit 126. Each sensor data 421 stored in the queue 420 has a pointer pointing to the immediately preceding sensor data 421 and the immediately following sensor data 421. The latest sensor data 422 is added to the end of the queue 420.

FIG. 7 is a diagram showing a hardware configuration of the data processing device according to the present embodiment.
As shown in this figure, the data processing device 100 includes hardware such as a CPU (Central Processing Unit) 101, a ROM (Read Only Memory) 102, a RAM (Random Access Memory) 103, a mass storage device 104, and a communication module 105. It is a computer equipped with.

FIG. 8 is a flowchart showing the flow of data processing according to this embodiment.
The data processing device 100 executes the data processing shown in the figure when the sensor data is received from the sensor unit 200.

First, the data write determination unit 123 reads the data write determination information stored in the data write determination information storage unit 122, and determines the load status of the system based on the read data write determination information (step S101). ..

Subsequently, the data write determination unit 123 determines whether or not the load status of the system is high load (step S102). More specifically, the data write determination unit 123 loads a high load when the queue retention rate in the read system load status management table is equal to or higher than the stay rate threshold value or when the CPU usage rate is equal to or higher than the usage rate threshold value. Judge that there is. When the system load condition is not high (normal) (step S102; NO), the data write determination unit 123 proceeds to the process of step S108 and writes the sensor data received unconditionally to the queue. Process as.

On the other hand, when the system load condition is high (step S102; YES), the data writing determination unit 123 is based on the read coordinates of each point in the important base coordinate management table and the coordinate data indicated by the sensor data. , The distance between the aircraft (sensor unit 200) and each point is calculated. Then, the data writing determination unit 123 reads out and obtains the writing time interval corresponding to the calculated distance to each point from the important site coordinate management table (step S103). For example, in the data example shown in FIG. 4, when the distance between the point “airport A” and the aircraft is 45 km, the writing time interval of the sensor data is 30 seconds.

Subsequently, the data writing determination unit 123 selects the minimum value from the writing time intervals obtained for each point (step S104). Then, the data write determination unit 123 reads the last processed data generation time corresponding to the sensor ID of the received sensor data from the determination time management table. Then, the data writing determination unit 123 compares the occurrence time indicated by the received current sensor data with the read previous process data occurrence time (step S105). Then, the data write determination unit 123 determines whether or not the generation time indicated by the current sensor data has passed the write time interval from the previous processed data generation time (step S106). When the writing time interval has not elapsed (step S106; NO), the data writing determination unit 123 discards the sensor data received as the non-writing target and ends the process.

On the other hand, when the write time interval has elapsed (step S106; YES), the data write determination unit 123 calculates the difference between the generation time of the received sensor data and the reception time of receiving the sensor data ( Step S107). This time difference is effective information when a lag occurs due to staying during data transmission/reception between the sensor unit 200 and the data receiving unit 11, and can be output as additional information of the aircraft position on the display 300. The data writing determination unit 123 adds the calculated time difference to the sensor data.

After that, the data writing determination unit 123 updates the determination time management table by rewriting the last processed data generation time corresponding to the sensor ID of the received sensor data to the generation time included in the received sensor data (step S108). ).

Then, the data write determination unit 123 outputs a write request to the queue registration unit 124. The queue registration unit 124 adds the sensor data included in the input write request to the end of the queue 420 of the corresponding sensor ID (step S109). More specifically, the queue registration unit 124 determines whether or not the queue 420 corresponding to the sensor ID included in the sensor data already exists in the queue storage unit 125. If the queue 420 corresponding to the sensor ID does not exist, the queue registration unit 124 creates a pair of the corresponding queue control information 410 and the queue 420, and writes the sensor data in the created queue 420. After that, the queue registration unit 124 transmits a retrieval request including the sensor ID of the added sensor data to the queue retrieval unit 126. On the other hand, when the queue 420 corresponding to the sensor ID exists, the queue registration unit 124 writes the sensor data at the end of the queue 420 and adds the sensor data to the queue, and the queue extraction request including the sensor ID of the added sensor data is taken out. It is output to the unit 126.

The queue retrieving unit 126 retrieves the sensor data 421-1 from the head of the queue 420 according to the retrieval request input from the queue registering unit 124. Then, the queue extracting unit 126 rewrites and updates the head position pointer 412 so as to point to the next sensor data 421-2. After that, the queue extracting unit 126 outputs a write request including the extracted sensor data to the data writing unit 13. When the writing request is input from the queue extracting unit 126, the data writing unit 13 writes the sensor data included in the writing request into the database stored in the storage device 14 (step S110). After that, the data writing unit 13 outputs a reading request including the sensor ID of the written sensor data to the data reading unit 15.

When the reading request is input from the data writing unit 13, the data reading unit 15 reads the sensor data of the sensor ID included in the reading request from the database stored in the storage device 14. Then, the data reading unit 15 outputs the read sensor data to the data output control unit 16. The data output control unit 16 uses the input sensor data to generate display data to be displayed on the display 300, and outputs the generated display data to the display 300 to update the display on the display 300 (step S111). Then, the process ends.

FIG. 9 is an image diagram showing an example of display data according to the present embodiment.
The display data illustrated in the figure is a history of aircraft position information, that is, a movement route of the aircraft.
FIG. 9A shows a history of aircraft position information when the load condition is normal (not high load). As shown in the figure, when the load condition is normal, the data processing device 100 writes all the received sensor data in the database, so that it is possible to display all the position information at the time points P1 to P7. ..

FIG. 9B shows a history of aircraft position information when the load condition is high in the related technology described above. This figure exemplifies a case where the load condition becomes high at time P4. As shown in the figure, in the related technology, since the position information at the time points P5 to P7 after the time point P4 when the load condition becomes high load is not written in the database, it is not possible to refer to the history of the position information during that time. ..

FIG. 9C shows a history of position information of the aircraft when the load condition is high load in the present invention. This figure exemplifies a case where the load condition becomes high at time P4. As shown in the figure, when the load status is high, the data processing apparatus 100 thins out the sensor data and writes it in the database. Therefore, the position information at the time point after the time P4 when the load status becomes high load Can be referred to. In the illustrated example, the data processing device 100 discards the sensor data at the time points P5 and P7 without writing the data in the database, and writes the sensor data at the time point P6 in the database. That is, in the present invention, when the load condition is high, it becomes possible to refer to the position information at the time point P6, which could not be referred to by the related technology. Therefore, the data processing device 100 according to the present embodiment can know the movement route of the aircraft in more detail than the related technology even when the load condition is high. In addition, the data processing apparatus 100 can properly prevent the sensor data to be thinned out to prevent the queue from being accumulated even when the load is high and prevent the performance deterioration from the data reception to the data reference.

If the sensor data includes a time difference between the generation time and the reception time, the data output control unit 16 may include the time difference in the display data. For example, the data output control unit 16 may display the time difference corresponding to each position information neighborhood as additional information. As a result, the operator US can know the time lag (time difference) from the generation time of the sensor data to the reception time, the time when the data processing device 100 has a high load, and the like.

As described above, the data processing device 100 according to the present embodiment stores the data in the queue storage unit 125 that temporarily stores the data in the queue, the load status detection unit 121 that detects the load on the own device, and the data when the load is high. A data write determination information storage unit 122 that stores information serving as a reference for writing, and a data write determination unit that determines whether to write data in the queue according to the reference when the detected load is equal to or greater than a predetermined threshold value. 123, a queue registration unit that writes the data determined to be written into the queue, and a queue extraction unit 126 that extracts the data from the queue in order to write the data in the database.

With such a configuration, the data processing device 100 does not write unnecessary data to the queue and writes only necessary data to the queue when the load is high. Therefore, the data is appropriately thinned to obtain both the latest information and the history information. Can be referred to at any time. Further, the data processing device 100 can prevent the data from staying in the queue in advance and prevent the performance from deteriorating due to the delay from the reception of the data to the reference of the data.

Further, the data write determination information storage unit 122 stores a time interval for writing data, and when the detected load is equal to or higher than a predetermined threshold, the data write determination information storage unit 122 generates the time when the previously written data occurs. It is determined that the data is written to the queue when the time interval has passed from. With such a configuration, the data processing device 100 can write data at time intervals with a high load.

Further, the data includes position information, the data writing determination information storage unit 122 stores the time interval according to the distance from the predetermined point, and the data writing determination unit 123 determines the position information and the point indicated by the data. Whether or not to write data to the queue is determined based on the time interval according to the distance from the. With such a configuration, it is possible to prevent necessary data from being lost even when the load is high, for example, by shortening the write time interval as the location gets closer to the important base.

In addition, the data writing determination information storage unit 122 stores the time interval corresponding to each distance from each of the plurality of points, and the data writing determination unit 123 determines the position information indicated by the data and the distance between the points. Based on the minimum value of the time intervals, it is determined whether or not to write the data in the queue. With such a configuration, for example, by shortening the writing time interval at an important point and lengthening the writing time interval at an unimportant point to some extent, unnecessary data can be appropriately thinned out at high load, and only necessary data can be written. it can.

The load is the retention rate in the queue or the usage rate of the central processing unit in the data processing apparatus 100. As a result, when the retention rate in the queue becomes high, or when the usage rate of the central processing unit becomes high, the data to be written in the queue is thinned out to retain the data in the queue, or The applied load can be reduced.

The data is the data sensed by the sensor, the queue exists for each sensor unit 200, and the data write determination unit 123 determines whether or not the data is written in the queue for each sensor unit 200. With such a configuration, it is possible to thin out the data to be written for each sensor unit 200.

Although one embodiment of the present invention has been described above, the present invention is not limited to the above embodiment, and various modifications can be made without departing from the spirit of the present invention.

For example, in the above-described embodiment, the queue extracting unit 126 and the data reading unit 15 execute the process after receiving the request. However, the present invention is not limited to this, and the queue extracting unit 126 and the data reading unit 15 are regularly activated to execute the process. 14 may be polled.

Further, in the above-described embodiment, a case has been described in which the number of storage devices 14 that store the database is one.

Further, in the above-described embodiment, the case where the data write determination information serving as the reference for writing data at the time of high load is the time interval for writing data has been described, but the present invention is not limited to this, and for example, the position information included in data is Other criteria, such as writing data when it is within a predetermined range from a predetermined point, may be used. The data write determination information can be freely set by the system user.
