Description

  The present invention relates to a situation management apparatus, a situation management method, and a situation management program for managing the situation of a target such as an aircraft.

  Situation grasping systems that grasp the situation are used in various fields. In the situation grasping system, for example, data related to the current situation of the aircraft may be acquired, and a display screen may be generated from the acquired data and displayed. The operator can grasp the current state of the aircraft with reference to the display screen. In the situation grasping system, since the current aircraft situation is used later, the display screen is stored in the storage device together with the current time information, and may be read from the storage device when necessary.

  On the other hand, there may be no storage device having a sufficient storage capacity for storing all display screens. Further, when all the display screens are stored in the storage device, it becomes difficult to select a necessary display screen from a large number of display screens when read later. Therefore, when not storing all the display screens in the storage device, only the display screens determined as necessary by the operator referring to the display screens are selected and stored in the storage device.

  Conventionally, for example, in order to limit the capacity of data to be stored in a storage device, there has been a monitoring method for acquiring data according to the degree of importance or for determining the lifetime of data (see, for example, Patent Document 1).

In the method described in Patent Document 1, it is considered that the attribute information of data is rewritten and data is accumulated by dynamically managing the duplication and importance of the data. It does not take into account the situation.
JP 2005-25533 A

  In the conventional situation grasping system described above, a display screen that is a plurality of still images is stored in a storage device. Therefore, when an operator selects and displays a necessary display screen, it is difficult to select the necessary display screen and it is inconvenient to grasp the overall situation in a general manner.

  Further, when the display screen is stored in the storage device by the operator's selection operation as in the conventional case, the operator needs to constantly monitor the display screen. In addition, selecting a display screen that is always stored in the storage device under the same conditions requires excessive attention to the operator, and there is a risk that the display screen is not stored in the storage device under the same conditions.

  Therefore, an object of the present invention is to provide a situation management device, a situation management method, and a situation management program that can efficiently grasp the situation of a target in a command and control system.

  The situation management device according to the feature of the present invention is based on an input unit that inputs external data including information related to an aircraft, a condition determination unit that determines whether the external data satisfies a predetermined condition, and external data A situation screen generation unit that generates image data in which information is drawn on a map around the aircraft and a situation diagram management unit that stores image data generated based on external data that satisfies a condition in a situation diagram database together with the condition With.

  According to the present invention, the status of a target can be efficiently grasped in a command and control system.

<Status management device>
As shown in FIG. 1, the status management device 1 includes a data input unit 11 for inputting external data D1 including information on a target (hereinafter referred to as an aircraft), and whether the external data D1 satisfies a predetermined condition. A condition determining unit 14 that determines whether or not, a situation screen generating unit 12 that generates situation screen data D2 in which information is drawn on a map around the aircraft based on the external data D1, and external data D1 that satisfies the condition. And a situation diagram management unit 16 for storing the situation screen data D2 generated based on the situation diagram data D3 in the situation diagram saving database 17 together with conditions.

  In the situation management device 1, data detected by a plurality of sensors provided in the aircraft is input to the data input unit 11 as external data D1. The external data D1 input to the data input unit 11 is output to the status screen generation unit 12 and the condition determination unit 14.

  The external data D1 is the situation of the aircraft itself equipped with the sensor and the situation of other aircraft detected by the sensor, and includes, for example, “target ID”, “event type”, “position information”, “speed”, etc. Yes. “Target ID” is an identifier of an aircraft or the like (target) that is the object of information in the external data D1. For example, when the external data D1 relates to aircraft flight information, the “target ID” is an identifier of the aircraft (target), and the “event type” is an identifier indicating that the information is related to aircraft flight. “Position information” is position information (current position) such as latitude, longitude, altitude, etc. of the current aircraft (at the time of external data generation) detected by the position detection sensor. “Speed” is a speed detection sensor. The detected flight speed of the aircraft.

  Here, when the external data D1 is data relating to the aircraft itself including the sensor, the “target ID” is an identifier of the aircraft including the sensor. On the other hand, when the external data D1 is generated by an aircraft sensor detecting information on another aircraft or the like, the “target ID” is an identifier of the detected other aircraft or the like.

  The status screen generation unit 12 generates status screen data D2 based on the input external data D1, stores the generated status screen data D2 in a memory (not shown), and outputs it to the status screen display processing unit 13. To do.

  As described above, the external data D1 includes information such as the target ID, event type, position information, and speed, but the situation screen data D2 is specified by the position information as shown in FIG. A target symbol x, target position information y, target speed z, and the like are drawn on a surrounding map.

  When the status screen display processing unit 13 inputs the status screen data D2 from the status screen generation unit 12, the status screen display processing unit 13 displays it on a connected display device (not shown). This situation diagram data D2 is real-time data, and the operator can grasp the real-time situation of the aircraft specified by all the external data D1 by referring to the situation screen data D2 displayed on the display device. it can.

  When the input external data D1 satisfies a predesignated condition, the condition determination unit 14 outputs a request R, assuming that the situation diagram data D3 is to be generated. As shown in FIG. 1, the condition determination unit 14 determines whether or not the condition is satisfied and outputs a request. As shown in FIG. 1, the condition target specifying unit 14a, the reference position management unit 14b, the reference position database (reference position DB) 14c, a moving distance calculating unit 14d, a distance specifying unit 14e, a moving distance determining unit 14f, an event specifying unit 14g, and an event determining unit 14h.

  When the target ID and the reference position for specifying the target for which the situation diagram data D3 is generated are input by the operation from the operator, the reference target specifying unit 14a outputs the target ID to the reference position management unit 14b. The reference position management unit 14b associates the input target ID and the reference position and accumulates them in the reference position DB 14c.

  In the reference position DB 14c, as in the example illustrated in FIG. 3, the reference position and time are associated with the target ID. The “reference position” is position information serving as a reference for calculating the moving distance of the target, and “time” is the time when the target is present at the reference position.

  When the movement distance calculation unit 14d receives the external data D1 related to the target registered in the reference position DB 14c, the movement distance calculation unit 14d extracts the reference position of the target from the reference position DB 14c via the reference position management unit 14b and extracts the extracted reference The position is compared with the position information (current position) included in the external data D1, and a moving distance I1 that is a distance that the target has moved from the reference position is calculated. In addition, the movement distance calculation unit 14d outputs the calculated movement distance I1 to the movement distance determination unit 14f.

  When the distance I2 for specifying the timing for generating the situation diagram data D3 is input by an operation from the operator via the distance specifying unit 14e, the moving distance determination unit 14f stores the input distance I2 in a memory (not shown). )). In addition, when the movement distance determination unit 14f inputs the movement distance I1 from the movement distance calculation unit 14d, whether or not the input movement distance I1 exceeds the distance I2 stored in the memory (I1 ≧ I2). judge. When the movement distance I1 ≧ distance I2, the movement distance determination unit 14f outputs a request R for requesting generation of the situation diagram data D3 to the situation screen acquisition unit 15.

  As described above, the condition determination unit 14 can generate the situation diagram data D3 when the movement distance I1 of the target designated by the operator becomes the predetermined distance I2.

  In addition, the condition determination unit 14 can generate the situation diagram data D3 when the external data D1 is data related to a specific event.

  The event type that specifies the timing for generating the situation diagram data D3 is input by the event determination unit 14h through the event designation unit 14g by an operation from the operator, and is stored in a memory (not shown). In addition, when the external data D1 is input from the data input unit 11, the event determination unit 14h determines whether or not the event type included in the external data D1 is an event type stored in the memory. When the event type included in the external data D1 is an event type stored in the memory, the event determination unit 14f outputs a request R for requesting generation of the situation diagram data D3 to the situation screen acquisition unit 15.

  When the request screen R is input from the movement distance determination unit 14f or the event determination unit 14h, the status screen acquisition unit 15 acquires the status screen data D2 from the status screen generation unit 12 and outputs it to the status diagram management unit 16. The status screen data D2 acquired here is data generated from the external data D1 that is the target of output of the request R by the condition determination unit 14.

  The situation diagram management unit 16 generates situation diagram data D3 based on the entered situation screen data D2. The situation diagram management unit 16 additionally stores the generated situation diagram data D3 in the situation diagram storage DB 17 together with the target ID and event type, which are the conditions used in the determination by the condition determination unit 14, and stores the generated situation diagram data D3. The figure data D3 is output to the situation diagram display processing unit 18.

  The situation diagram display processing unit 18 displays the inputted situation diagram data D3 on the connected display device. This situation diagram data D3 is still image data at the time of a specific event, and is displayed on the display device and used when it becomes necessary. For example, the situation diagram display processing unit 18 displays the situation diagram data D3 on the display device at the newly generated timing. Further, the situation diagram display processing unit 18 displays the situation diagram data D3 read from the situation diagram saving DB 17 on the situation diagram management unit 16 on the display device in response to a request from the operator.

  When the request for displaying the situation diagram data D3 from the operator includes conditions such as the event type and the target ID, the situation diagram management unit 16 uses the situation diagram data D3 specified by these conditions as the situation diagram. The situation diagram data D3 read from the storage DB 17 and read by the situation diagram display processing unit 18 on the display device is displayed.

  The status management device 1 is a general computer that includes a central processing unit, a storage device, a memory, an input / output interface, and the like (not shown). A status management program (not shown) stored in the storage device is read out and executed by the central processing unit, so that the data input unit 11, the status screen generation unit 12, and the status screen display process as shown in FIG. The situation management apparatus 1 including the unit 13, the condition determination unit 14, the situation screen acquisition unit 15, the situation diagram management unit 16, and the display processing unit 18 is realized.

The event determination process to be determined will be described.

  Since the event determination process is executed, in the condition determination unit 14, the event type specified by the operator in the event specification unit 14g is stored in the memory in advance.

  When the external data D1 is input from the data input unit 11 (S21), the event determination unit 14h determines whether or not the event included in the external data D1 is an event type stored in the memory (S22).

  When the event type of the input external data D1 is an event type stored in the memory in advance (YES in S22), the event determination unit 14h outputs a request R that requests generation of the situation diagram data D3 (S23). .

<Moving distance judgment processing>
Using the flowchart shown in FIG. 5, when the external data D1 is input by the situation management apparatus 1, the condition determination unit 14 determines the movement distance of the external data D1 and determines whether to generate the situation diagram data D3. The movement distance determination process will be described.

  In the condition determining unit 14, the reference position of the target specified by the operator in the reference target specifying unit 14a is accumulated in the reference position DB 14c. Further, in the condition determination unit 14, the distance I2 that is a comparison target with the movement distance input by the operator via the distance designation unit 14e is stored in the memory.

  When the external data D1 is input from the data input unit 11 (S31), the moving distance calculation unit 14d determines whether or not the external data D1 is data relating to a predetermined target (S32). Specifically, the movement distance calculation unit 14d determines whether or not the reference position of the target ID included in the external data D1 is stored in the reference position DB 14c.

  When the data is related to the predetermined target, the movement distance calculation unit 14d extracts the reference position associated with the target ID from the reference position DB 14c (S33), and based on the reference position and the current position included in the external data D1. The movement distance I1 is calculated and output to the movement distance determination unit 14f (S34).

  The movement distance determination unit 14f determines whether or not the input movement distance I1 is greater than or equal to a predetermined distance I2 (S35).

  When the movement distance I1 is equal to or greater than the predetermined distance I2 (YES in S35), the movement distance determination unit 14f outputs a request R that requests generation of the situation diagram data D3 (S36).

<Situation diagram data management processing>
An example of a process in which the request R is output from the condition determination unit 14 and the situation diagram data D3 is generated in the situation management device 1 will be described using the flowchart shown in FIG.

  The status screen acquisition unit 15 that has input the request R (S41) acquires the status screen data D2 from the status screen generation unit 12 and outputs it to the status diagram management unit 16 (S42).

  The situation diagram management unit 16 generates situation diagram data D3 from the entered situation screen data D2, and stores the situation diagram data D3 in the situation diagram storage DB 17 together with the conditions used for the determination of the external data D1 by the condition determination unit 14. (S43).
