The first embodiment will be described with reference to FIGS.

FIG. 1 is a diagram illustrating an example of a configuration of an airport 610 in which the moving object monitoring apparatus 100 according to this embodiment monitors an aircraft 621 (an example of a moving object).
The airport 610 has a runway 611. Both ends of the runway 611 are referred to as a start end 612 and a termination end 613. The aircraft 621 is assumed to move from the start end 612 side toward the end end 613 side. That is, the take-off aircraft 621 accelerates and takes off from the vicinity of the start end 612 toward the end 613, and the landing aircraft 621 departs near the start end 612 and decelerates to the end 613 to land. Therefore, when the runway 611 is used in the reverse direction due to the wind direction or the like, the names of the start end 612 and the end end 613 are reversed. A line segment that is the center of the runway 611 in the longitudinal direction is referred to as a center line 614.

There are a large number of aircrafts 621 in the vicinity of the runway 611. The aircraft 621 existing in the vicinity of the runway 611 can be broadly divided into a departure aircraft, an arrival aircraft, and a crossing aircraft. The departure aircraft is an aircraft 621 taking off from the airport 610, an aircraft 621 waiting on a taxiway near the runway 611, an aircraft 621 moving to the runway 611, an aircraft 621 accelerating for takeoff, and taking off. An aircraft 621 floating on the runway 611, an aircraft 621 flying on an extension line of the runway 611, and the like. The arrival aircraft is an aircraft 621 landing at the airport 610. In preparation for landing, the aircraft 621 is descending toward the runway 611 with the extended line of the runway 611, and is landing on the runway 611. An aircraft 621, an aircraft 621 landing on a runway 611, an aircraft 621 decelerating to stop, an aircraft 621 moving on the ground from the runway 611 toward the taxiway, and the like. The crossing machine is an aircraft 621 that crosses the runway 611 to move to the other side of the runway 611 instead of entering the runway 611 for takeoff or landing, and waits on a taxiway near the runway 611. An aircraft 621 that is crossing the runway 611, an aircraft 621 that has moved across to the other taxiway, and the like.
Thus, there are a large number of aircrafts 621 moving for various purposes near the runway 611. By appropriately guiding these aircraft 621, the utilization efficiency of the runway 611 can be improved and the number of arrivals and departures of the aircraft 621 can be increased.

  The airport 610 includes a moving body detection device that detects the position of the aircraft 621 by an airport surface detection radar or a multilateration system (not shown).

The moving body data stored in the moving body storage unit 120 includes not only the position and flight number of the aircraft 621 but also information such as the moving speed and state (whether it is a departure aircraft or an arrival aircraft). These pieces of information may be configured to be detected and output by the mobile object detection device, or the mobile object input unit 110 may calculate the moving speed from the position of the aircraft 621 or refer to the flight plan for the aircraft 621. It is also possible to obtain the state of and add to the mobile data.
The mobile body display unit 130 uses the display device 901 to plot the position of the aircraft 621 on the map of the airport 610 based on the mobile body data stored in the mobile body storage unit 120 in a format that is easy for the controller to understand. indicate.

  The block generation rule storage unit 140 stores block generation rule data in advance using the magnetic disk device 920. Block generation rule data is data representing a block generation rule. The block generation rule is a rule for generating an occupied block of the aircraft 621 based on information such as the position of the aircraft 621. The occupied block is data representing an area occupied by the aircraft 621. The mobile monitoring apparatus 100 generates information for appropriately guiding the aircraft 621 by determining the overlap of the occupied blocks.

Using the CPU 911, the block generation unit 150 inputs the mobile body data stored in the mobile body storage unit 120 and the block generation rule data stored in the block generation rule storage unit 140.

And give a warning sound or a message.

FIG. 5 is a flowchart showing an example of the flow of the block generation process S400 in this embodiment.
In the block generation process S400, the block generation unit 150 generates an occupied block of the aircraft 621 for the runway 611. When there are a plurality of runways 611 in the airport 610, the block generation unit 150 generates an occupied block for each runway 611. The block generation process S400 includes a state determination step S410, an arrival machine block generation process S420, a departure machine block generation process S430, and a crossing machine block generation process S440.

  In the state determination step S410, the block generation unit 150 uses the CPU 911 to acquire mobile body data for one aircraft 621 from the mobile body data stored in the mobile body storage unit 120. The block generation unit 150 uses the CPU 911 to determine whether the aircraft 621 is an arrival aircraft arriving at the runway 611 or a departure aircraft departing from the runway 611 based on the acquired moving body data. It is determined whether the aircraft is crossing the runway 611 or irrelevant to the runway 611 (such as an aircraft that does not cross the runway 611 and takes off and landing on another runway). If it is determined that the aircraft is an arrival aircraft, the process proceeds to arrival aircraft block generation processing S420. If it is determined that the aircraft is a departure aircraft, the flow advances to departure aircraft block generation processing S430. When it determines with a crossing machine, it progresses to crossing machine block production | generation process S440. If it is determined that they are irrelevant, the block generation process S400 is terminated.

  In the arrival unit block generation process S420, the block generation unit 150 uses the CPU 911 to acquire block generation rule data for the arrival unit from the block generation rule data stored in the block generation rule storage unit 140. Using the CPU 911, the block generation unit 150 generates an occupied block of the aircraft 621 based on the block generation rule represented by the acquired block generation rule data and the mobile body data acquired in the state determination step S410. Thereafter, the block generation process S400 is terminated.

  In the departure machine block generation process S430, the block generation unit 150 uses the CPU 911 to acquire block generation rule data for the departure machine from the block generation rule data stored in the block generation rule storage unit 140. Using the CPU 911, the block generation unit 150 generates an occupied block of the aircraft 621 based on the block generation rule represented by the acquired block generation rule data and the mobile body data acquired in the state determination step S410. Thereafter, the block generation process S400 is terminated.

  In the crossing block generation processing S440, the block generation unit 150 uses the CPU 911 to acquire block generation rule data for the crossing from the block generation rule data stored in the block generation rule storage unit 140. Using the CPU 911, the block generation unit 150 generates an occupied block of the aircraft 621 based on the block generation rule represented by the acquired block generation rule data and the mobile body data acquired in the state determination step S410. Thereafter, the block generation process S400 is terminated.

FIG. 6 is a flowchart showing an example of the flow of the arrival unit block generation process S420 in this embodiment.
The arrival machine block generation process S420 includes a start distance determination step S421, an occupied block generation step S422, a fully occupied block generation step S424, a departure distance determination step S426, and a forward occupied block generation step S427.

In the start distance determination step S421, the block generation unit 150 uses the CPU 911 to calculate the plane distance d between the aircraft 621 and the start end 612 of the runway 611 based on the moving body data acquired in the state determination step S410. To do. The block generation unit 150 uses the CPU 911 to acquire two threshold values D ₁ and D ₂ (where 0 <D ₁ <D ₂ ) from the block generation rule data stored in the block generation rule storage unit 140. The block generation unit 150 uses the CPU 911 to compare the calculated plane distance d with the two threshold values D ₁ and D ₂ .
If the plane distance d is the threshold value D ₂ or terminates the arriving aircraft block generation processing S420. That is, the occupation block of the aircraft 621 is not generated. This is because it is not necessary to occupy the runway 611 because the aircraft 621 is still sufficiently away from the runway 611.
If the plane distance d is a threshold value _{D 1} or more and less than the threshold value _{D 2,} the process proceeds to occupy scheduled block generating step S422.
If the plane distance d is less than 0 or more and the threshold D _1, the process proceeds to all occupied already block generating step S424.
When the plane distance d is less than 0, the process proceeds to the separation distance determination step S426. The plane distance d is positive in the direction from the start end 612 toward the outside of the runway 611. That is, the case where the plane distance d is less than 0 means the case where the aircraft 621 is on the runway 611 or the runway 611. Note that here, only the aircraft 621 that is about to land on the runway 611 is targeted, so even if it is above the runway 611, it is within the range of the height that is landing, and the far runway 611 is far away. Aircraft 621 flying over the sky and aircraft 621 trying to stop landing and leave are excluded.

  In the occupancy planned block generation step S422, the block generation unit 150 uses the CPU 911 to generate an occupancy planned block that covers the entire range from the start end 612 to the end 613 of the runway 611. The occupation block is an occupation block that is generated mainly for the purpose of monitoring the other aircraft 621 and does not have the effect of eliminating the other aircraft 621 among the occupied blocks. The block storage unit 160 uses the magnetic disk device 920 to store the planned occupation block generated by the block generation unit 150. Thereafter, the arrival machine block generation process S420 is terminated.

  In the all-occupied block generation step S424, the block generation unit 150 uses the CPU 911 to generate an occupied block that covers the entire area from the start end 612 to the end 613 of the runway 611. The occupied block is an occupied block having an effect of excluding other aircraft 621 among the occupied blocks. The block storage unit 160 stores the occupied blocks generated by the block generation unit 150 using the magnetic disk device 920. Thereafter, the arrival machine block generation process S420 is terminated.

In the separation distance determination step S426, the block generation unit 150 uses the CPU 911 to calculate the distance w between the aircraft 621 and the center line 614 of the airport 610 based on the moving body data acquired in the state determination step S410. To do. Block generating unit 150, by using the CPU 911, the block generation stored data block generation rule storage unit 140 is stored, and acquires the threshold value _{W 1.} Block generating unit 150, by using the CPU 911, compares the distance w which calculated with a threshold value _{W 1} acquired.
If the distance w is the threshold value W ₁ or terminates the arriving aircraft block generation processing S420. That is, the occupation block of the aircraft 621 is not generated. This is to release the runway 611 when the aircraft 621 has landed on the runway 611 and is sufficiently away from the runway 611.
If the distance w is smaller than the threshold W _1, the process proceeds to the front occupied already block generating step S427.

  In the forward occupied block generation step S427, the block generation unit 150 uses the CPU 911 to acquire the current position of the aircraft 621 based on the moving body data acquired in the state determination step S410. The block generation unit 150 uses the CPU 911 to generate an occupied block ranging from the acquired current position of the aircraft 621 to the end 613 of the runway 611. The block storage unit 160 stores the occupied blocks generated by the block generation unit 150 using the magnetic disk device 920. Thereafter, the arrival machine block generation process S420 is terminated.

FIG. 7 is a diagram illustrating an example of the occupied block 511 generated by the block generation unit 150 in the arrival unit block generation processing S420 in this embodiment.
If the plane distance d is less than the threshold _{D 1} or more and the threshold _{D 2} between the starting end 612 of the aircraft 621 and the runway 611, the block generator 150, in occupancy schedule block generating step S422, from the beginning 612 of runway 611 An occupancy planned block 511 that covers the entire area up to the end 613 is generated. Thereby, it will be in the state which monitors whether the other aircraft 621 exists in the full range of the runway 611 which the aircraft 621 is going to land from now on.
When there is a block occupied by another aircraft 621 on the runway 611, the alerting unit 180 alerts the controller, and the controller determines whether to stop the landing of the aircraft 621. For example, if another aircraft 621 having an occupied block on the runway 611 is an arrival aircraft that has already landed on the runway 611 and will soon depart from the runway 611, the controller will execute the landing of the aircraft 621. to decide.

  In this way, the mobile monitoring device 100 does not mechanically determine whether or not to stop the landing of the aircraft 621, but it is left to the controller to make a flexible operation, and the use of the runway 611 is possible. Efficiency can be increased. Also, in situations where the controller's judgment is necessary, the alerting unit 180 alerts the controller's attention, so that it is possible to prevent an accident from being overlooked by the controller. Furthermore, since the controller can concentrate on the determination of the situation where the alerting unit 180 has attracted attention, the controller can make a more appropriate determination, and the use efficiency of the runway 611 can be improved.

FIG. 8 is a diagram illustrating an example of the occupied block 521 generated by the block generation unit 150 in the arrival unit block generation processing S420 in this embodiment.

As a result, the aircraft 621 is excluded from the entire range of the runway 611 to be landed.
When there is a block occupied by another aircraft 621 on the runway 611, the alerting unit 180 alerts the controller, and the controller determines whether to stop the landing of the aircraft 621. The alerting unit 180 also alerts the other aircraft 621 side. When it is determined that the landing of the aircraft 621 is performed, the controller removes the other aircraft 621 from the runway 611 promptly.

FIG. 9 is a diagram showing an example of the occupied block 521 generated by the block generation unit 150 in the arrival unit block generation processing S420 in this embodiment.
When the aircraft 621 enters the runway 611 beyond the start end 612 of the runway 611 and the plane distance d between the aircraft 621 and the start end 612 of the runway 611 becomes negative, the block generator 150 In the occupied block generation step S427, an occupied block 521 that covers the range from the current position of the aircraft 621 to the end 613 of the runway 611 is generated. As a result, the other aircraft 621 is excluded from the front of the aircraft 621, but the other aircraft 621 is allowed to enter behind the aircraft 621.

FIG. 10 is a diagram illustrating an example of the occupied block 521 generated by the block generation unit 150 in the arrival unit block generation processing S420 in this embodiment.
Similarly, when the aircraft 621 has landed on the runway 611 and is decelerating, the block generation unit 150 covers the range from the current position of the aircraft 621 to the end 613 of the runway 611 in the forward occupied block generation step S427. An occupied block 521 is generated.

FIG. 11 is a diagram illustrating an example of the occupied block 521 generated by the block generation unit 150 in the arrival unit block generation processing S420 in this embodiment.
Aircraft 621 is sufficiently decelerated after landing, even if you are trying to leave the runway 611, if the distance w is less than the threshold value W ₁ between the center line 614 of the aircraft 621 and the runway 611, still The block generation unit 150 generates the occupied block 521 that covers the range from the current position of the aircraft 621 to the end 613 of the runway 611 in the forward occupied block generation step S427.

FIG. 12 is a diagram illustrating an example in which the block generation unit 150 does not generate an occupied block in the arrival unit block generation processing S420 in this embodiment.
Aircraft 621 is completely disengaged from the runway 611, if the distance w between the center line 614 of the aircraft 621 and the runway 611 becomes the threshold value _{W 1} or more, the block generator 150, the occupied block of aircraft 621 Do not generate.

FIG. 13 is a flowchart showing an example of the flow of the departure machine block generation process S430 in this embodiment.
The departure machine block generation process S430 includes an approach distance determination step S431, an occupied planned block generation step S432, a speed determination step S433, a forward occupied planned block generation step S434, a rear occupied block generation step S435, and a forward occupied block generation step S436. Have.

In the approach distance determination step S431, the block generation unit 150 uses the CPU 911 to calculate the distance w between the aircraft 621 and the center line 614 of the runway 611 based on the moving body data acquired in the state determination step S410. To do. Using the CPU 911, the block generation unit 150 acquires two threshold values W ₂ and W ₃ (W ₂ <W ₃ ) from the block generation rule data stored in the block generation rule storage unit 140. The block generation unit 150 uses the CPU 911 to compare the calculated distance w with the two threshold values W ₂ and W ₃ .
If the distance w is the threshold value W ₃ or ends the departing aircraft block generation processing S430. That is, the occupation block of the aircraft 621 is not generated. This is because it is not necessary to occupy the runway 611 because the aircraft 621 is still sufficiently away from the runway 611.
If the distance w is less than the threshold _{W 2} or more and the threshold _{W 3} being proceeds to occupy scheduled block generating step S432.
If the distance w is less than the threshold _{W 2} proceeds to the speed determination step S433.

  In the occupation-scheduled block generation step S432, the block generation unit 150 uses the CPU 911 to calculate the position on the runway 611 that the aircraft 621 is about to enter based on the moving body data acquired in the state determination step S410. The block generation unit 150 uses the CPU 911 to generate an occupation-scheduled block that covers a predetermined area before and after the calculated position. The block storage unit 160 uses the magnetic disk device 920 to store the planned occupation block generated by the block generation unit 150. Thereafter, the departure machine block generation process S430 is terminated.

In the speed determination step S433, the block generation unit 150 uses the CPU 911 to acquire the speed v of the aircraft 621 based on the moving body data acquired in the state determination step S410. The block generation unit 150 uses the CPU 911 to acquire the threshold value V ₁ from the block generation rule data stored in the block generation rule storage unit 140. Block generating unit 150, by using the CPU 911, compares the velocity v obtained with the threshold value _{V 1} obtained.
If the speed v is less than the threshold value V _1, the process proceeds to the front occupancy schedule block generating step S434.
If the speed v is the threshold value V ₁ or more, the process proceeds to the front occupied already block generating step S436.

In the forward occupancy planned block generation step S434, the block generation unit 150 uses the CPU 911 to acquire the current position of the aircraft 621 based on the moving body data acquired in the state determination step S410. Using the CPU 911, the block generation unit 150 generates an occupation-scheduled block having a range from the acquired current position of the aircraft 621 to the end 613 of the runway 611. The block storage unit 160 uses the magnetic disk device 920 to store the planned occupation block generated by the block generation unit 150.
In the backward occupied block generation step S435, the block generation unit 150 uses the CPU 911 to complete the occupation from the start end 612 of the runway 611 to the current position of the aircraft 621 acquired in the forward occupied block generation step S434. Generate a block. The block storage unit 160 stores the occupied blocks generated by the block generation unit 150 using the magnetic disk device 920. Thereafter, the departure machine block generation process S430 is terminated.

  In the forward occupied block generation step S436, the block generation unit 150 uses the CPU 911 to acquire the current position of the aircraft 621 based on the moving body data acquired in the state determination step S410. The block generation unit 150 uses the CPU 911 to generate an occupied block ranging from the acquired current position of the aircraft 621 to the end 613 of the runway 611. The block storage unit 160 stores the occupied blocks generated by the block generation unit 150 using the magnetic disk device 920. Thereafter, the departure machine block generation process S430 is terminated.

FIG. 14 is a diagram illustrating an example of the occupied block 512 generated by the block generation unit 150 in the departure block generation processing S430 in this embodiment.
Aircraft 621 approaches the runway 611 for takeoff, when the distance w between the center line 614 of the aircraft 621 and the runway 611 is less than the threshold value _{W 2} or more and the threshold _{W 3,} the block generator 150, occupies In the scheduled block generating step S432, an occupied scheduled block 512 that covers the range before and after the position on the runway 611 that the aircraft 621 is about to enter is generated. Thereby, it will be in the state which monitors whether there exists an occupation block of the other aircraft 621 in the position where the aircraft 621 is going to approach.
For example, when there is another aircraft 621 landing on the runway 611, if the other aircraft 621 is closer to the start end 612 than the position where the aircraft 621 is about to enter, the occupied block of the other aircraft 621 and the aircraft Since the 621 occupation schedule block 512 overlaps, the alerting unit 180 alerts the controller. For example, the controller instructs the aircraft 621 to wait for another aircraft 621 to pass.
On the other hand, if the other aircraft 621 is closer to the terminal 613 than the position where the aircraft 621 is about to enter, the occupied block of the other aircraft 621 and the planned occupied block 512 of the aircraft 621 will not overlap. The awakening unit 180 does not alert the controller. The controller allows the aircraft 621 to enter the runway 611. Accordingly, the aircraft 621 can enter the runway 611 and prepare for takeoff without waiting for the arrival aircraft to leave the runway 611, so that the use efficiency of the runway 611 is increased.

FIG. 15 is a diagram illustrating an example of the occupied block 513 and the occupied block 522 generated by the block generation unit 150 in the departure block generation processing S430 in this embodiment.
Aircraft 621 is further approaching the runway 611, if the distance between the center line 614 of the aircraft 621 and the runway 611 is less than the threshold value _{W 2,} the block generator 150, in front occupancy schedule block generating step S434 The block 513 that occupies the area from the current position of the aircraft 621 to the end 613 of the runway 611 is generated, and the range from the start end 612 of the runway 611 to the current position of the aircraft 621 is generated in the rear occupied block generation step S435. The occupied block 522 is generated. Accordingly, it is monitored whether there is another aircraft 621 in front of the aircraft 621, and the other aircraft 621 is excluded from the rear of the aircraft 621.
For example, when there is another aircraft 621 landing on the runway 611, if the other aircraft 621 is on the terminal 613 side, the occupied block of the other aircraft 621 and the planned occupied block 512 of the aircraft 621 overlap. The alerting unit 180 alerts the controller. For example, the controller instructs an aircraft 621 ready for takeoff to wait until another aircraft 621 leaves the runway 611.

FIG. 16 is a diagram illustrating an example of the occupied block 513 and the occupied block 522 generated by the block generation unit 150 in the departure block generation processing S430 in this embodiment.
Although aircraft 621 is accelerating for takeoff, still, a medium speed can be stopped immediately, when the velocity v of the aircraft 621 is less than the threshold value V _1, the block generator 150, in front of the aircraft 621 The occupied block 513 and the occupied block 522 are generated behind.
For example, if there is another aircraft 621 on the taxiway trying to take off from the runway 611 following the aircraft 621, the occupied block 512 of the other aircraft 621 and the occupied block 522 of the aircraft 621 overlap. The awakening unit 180 alerts the controller. The controller instructs, for example, another aircraft 621 to wait for entering the runway 611.

FIG. 17 is a diagram illustrating an example of the occupied block 523 generated by the block generation unit 150 in the departure machine block generation processing S430 in this embodiment.
Aircraft 621 is further accelerated, if the speed v of the aircraft 621 is the threshold value _{V 1} or more, the block generator 150, the occupancy already block 523 in a range from the current position of the aircraft 621 to the end 613 of runway 611 Generate. As a result, the other aircraft 621 is excluded from the front of the aircraft 621, but the other aircraft 621 is allowed to enter behind the aircraft 621.
For example, if there is another aircraft 621 on the taxiway trying to take off from the runway 611 following the aircraft 621, the scheduled block 512 of the other aircraft 621 and the occupied block 523 of the aircraft 621 do not overlap. The alerting unit 180 does not alert the controller. The controller allows other aircraft 621 to enter the runway 611. Thus, since the other aircraft 621 can enter the runway 611 and prepare for takeoff without waiting for the departure aircraft to take off, the use efficiency of the runway 611 is increased.

FIG. 18 is a diagram showing an example of the occupied block 523 generated by the block generation unit 150 in the departure machine block generation processing S430 in this embodiment.
Even if the aircraft 621 further accelerates and takes off, if the aircraft 621 is still on the runway 611, the block generator 150 occupies a range from the current position of the aircraft 621 to the end 613 of the runway 611. Block 523 is generated. As a result, the majority of the runway 611 is allowed to enter the other aircraft 621, but the other aircraft 621 is excluded from immediately below where the aircraft 621 passes.

FIG. 19 is a diagram illustrating an example of the case where the block generation unit 150 does not generate an occupied block in the departure machine block generation processing S430 in this embodiment.
When the aircraft 621 takes off and exceeds the end 613 of the runway 611, the block generation unit 150 does not generate an occupied block. As a result, the runway 611 is completely released, and another aircraft 621 is allowed to enter.

FIG. 20 is a flowchart showing an example of the flow of the crossing machine block generation processing S440 in this embodiment.
The crossing machine block generation process S440 includes an approach distance determination step S441, an occupied planned block generation step S442, and a rear occupied block generation step S443.

In the approach distance determination step S441, the block generation unit 150 uses the CPU 911 to calculate the distance w between the aircraft 621 and the center line 614 of the runway 611 based on the moving body data acquired in the state determination step S410. To do. In addition, the case where the aircraft 621 approaches the runway 611 trying to cross the runway 611 and the case where the aircraft 621 crosses the runway 611 and then moves away from the runway 611 are distinguished by the sign of the distance w. It shall be. That is, when the distance w is positive, it indicates that the aircraft 621 is about to cross the runway 611 and approaches the runway 611. When the distance w is negative, after the aircraft 621 crosses the runway 611, It represents that it is moving away from the runway 611. Using the CPU 911, the block generation unit 150 uses the block generation rule data stored in the block generation rule storage unit 140 to calculate three threshold values W ₁ , W ₂ , W ₃ (where 0 <W ₁ , 0 <W ₂ <W _3. ). Note that these threshold values may be the same as or different from those of the arrival aircraft and the departure aircraft. The block generation unit 150 uses the CPU 911 to compare the calculated distance w with the threshold value −W ₁ and the threshold values W ₂ and W _{3 obtained} by inverting the sign of the threshold value W ₁ .
If the distance w is less than the threshold _{W 2} or more and _{W 3} being proceeds to occupy scheduled block generating step S442.
If the distance w is greater than or equal to the threshold −W ₁ and less than the threshold W ₂ , the process proceeds to the backward occupied block generation step S 443.
In other cases, the crossing block generation processing S440 is terminated. That is, the block generation unit 150 does not generate an occupied block of the aircraft 621. This is because the aircraft 621 that is about to cross the runway 611 is still sufficiently away from the runway 611, or the aircraft 621 that has crossed the runway 611 is sufficiently away from the runway 611. It is because it is not necessary to occupy.

  In the planned occupation block generation step S442, the block generation unit 150 uses the CPU 911 to calculate the position on the runway 611 that the aircraft 621 is about to cross based on the moving body data acquired in the state determination step S410. The block generation unit 150 uses the CPU 911 to generate an occupation-scheduled block that covers a predetermined area before and after the calculated position. The block storage unit 160 uses the magnetic disk device 920 to store the planned occupation block generated by the block generation unit 150. Thereafter, the crossing block generation process S440 is terminated.

  In the backward occupied block generation step S443, the block generation unit 150 uses the CPU 911 to acquire the current position of the aircraft 621 based on the moving body data acquired in the state determination step S410. The block generation unit 150 uses the CPU 911 to generate an occupied block having a range from the start end 612 of the runway 611 to the acquired current position of the aircraft 621. The block storage unit 160 stores the occupied blocks generated by the block generation unit 150 using the magnetic disk device 920. Thereafter, the crossing block generation process S440 is terminated.

FIG. 21 is a diagram illustrating an example of the occupation-scheduled block 514 generated by the block generation unit 150 in the crossing block generation processing S440 in this embodiment.
If the aircraft 621 approaches the runway 611 to traverse the runway 611, the distance w between the center line 614 of the aircraft 621 and the runway 611 is less than the threshold value _{W 2} or more and the threshold _{W 3,} block generation In the occupation block generation step S442, the unit 150 generates the occupation block 514 that covers the range before and after the position on the runway 611 that the aircraft 621 is about to cross. As a result, the aircraft 621 monitors whether there is an occupied block of another aircraft 621 at a position where the aircraft 621 is about to cross.

FIG. 22 is a diagram illustrating an example of the occupied block 524 generated by the block generation unit 150 in the crossing block generation processing S440 in this embodiment.
When the aircraft 621 further approaches the runway 611 and the distance w between the aircraft 621 and the center line 614 of the runway 611 is greater than or equal to the threshold −W ₁ and less than the threshold W ₂ , the block generation unit 150 determines the runway An occupied block 524 ranging from the start end 612 of 611 to the current position of the aircraft 621 is generated. As a result, the other aircraft 621 is excluded from the start end 612 side of the aircraft 621.

FIG. 23 is a diagram illustrating an example of a case where the block generation unit 150 does not generate an occupied block in the crossing block generation processing S440 in this embodiment.
When the aircraft 621 leaves the runway 611 across the runway 611 and the distance w between the aircraft 621 and the center line 614 of the runway 611 is less than the threshold −W ₁ , the block generation unit 150 occupies Do not generate blocks.

  As described above, the block generation unit 150 generates an occupied block such as an occupied block or an occupied block based on the state / position / speed of the aircraft 621. The types and ranges of the occupied blocks of the aircraft 621 generated by the block generation unit 150 are not limited to those described above, and the block generation unit 150 may be configured to generate other types and ranges of occupied blocks. Good. Moreover, the structure which determines the kind and range of the occupation block which the block generation part 150 produces | generates based on the block production | generation rule data memorize | stored by the block production | generation rule memory | storage part 140 may be sufficient. Then, by updating the block generation rule data stored in the block generation rule storage unit 140, the type and range of the occupied blocks generated by the block generation unit 150 can be changed, and the mobile object monitoring apparatus 100 can be flexibly configured. Can be used.

FIG. 24 is a flowchart showing an example of the flow of the overlap determination process S450 in this embodiment.
In the overlap determination process S450, the moving object monitoring apparatus 100 determines the overlap of the occupied blocks and alerts the controller. The duplication determination process S450 includes a moving body selection step S451, an occupied block selection step S452, an overlap determination step S453, an occupied block repetition step S454, an alerting step S455, and a moving body repetition step S456.

  In the moving body selection step S451, the duplication determination unit 170 uses the CPU 911 to select the aircraft 621 one by one from the aircrafts 621 in which the block storage unit 160 stores the occupied blocks. The overlap determination unit 170 uses the CPU 911 to acquire the occupied block stored in the block storage unit 160 for the selected aircraft 621. When there is one occupied block stored in the block storage unit 160 for the selected aircraft 621, the duplication determination unit 170 uses the CPU 911 to set the acquired range of the occupied block as the duplication determination range. When there are a plurality of occupied blocks stored in the block storage unit 160 for the selected aircraft 621, the overlap determination unit 170 uses the CPU 911 to set a range belonging to at least one of the plurality of occupied blocks as the overlap determination range.

  In the occupied block selection step S452, the duplication determination unit 170 uses the CPU 911 to select the occupied blocks of the aircraft 621 other than the aircraft 621 selected in the moving object selection step S451 from the occupied blocks stored in the block storage unit 160. Select one by one.

In the overlap determination step S453, the overlap determination unit 170 uses the CPU 911 to determine whether there is overlap between the overlap determination range acquired in the moving object selection step S451 and the occupied block selected in the occupied block selection step S452. Determine whether or not.
If it is determined that there is no overlap, the process proceeds to the occupied block repetition step S454.
When it determines with duplication, it progresses to alerting process S455.

In the occupied block repetition step S454, the duplication determination unit 170 determines whether or not all the occupied blocks to be selected in the occupied block selection step S452 have been selected using the CPU 911.
If it is determined that there is an occupied block that has not yet been selected, the process returns to the occupied block selection step S452 to select the next occupied block.
If it is determined that all occupied blocks have been selected, the process proceeds to the moving object repetition step S456.

  In the alerting step S455, the alerting unit 180 uses the display device 901 to alert the controller, for example, by displaying an alerting message for the aircraft 621 selected in the moving object selection step S451.

In the moving body repetition step S456, the overlap determination unit 170 uses the CPU 911 to determine whether or not all the aircrafts 621 to be selected in the moving body selection step S451 have been selected.
If it is determined that there is an aircraft 621 that has not yet been selected, the process returns to the moving body selection step S451, and the next aircraft 621 is selected.
If it is determined that all the aircrafts 621 have been selected, the duplication determination process S450 ends.

FIG. 25 is a diagram showing an example of a screen displayed by the display device 901 in this embodiment.
On the display device 901, the moving body display unit 130 displays, for example, a map of the airport 610, the position of the aircraft 621, and the like. Further, on the display device 901, the alerting unit 180 displays, for example, an alerting message. The alerting unit 180 displays an alerting message so that the relationship with the aircraft 621 to which the controller should be alerted can be understood using, for example, blowing. In addition, the alerting unit 180 displays an alerting message so as to easily attract the attention of the controller, for example, by increasing the size of characters or changing the display color.
Note that the alerting unit 180 not only displays an alert message for the aircraft 621 in which the occupied blocks of the other aircraft 621 overlap with the occupied blocks, but also the occupied blocks of the other aircraft 621 are already occupied. The configuration may be such that an alert message is displayed for the aircraft 621 that overlaps the block. In that case, in order to express the difference in the alert level, the size and the display color of the character for displaying the alert message may be changed.

FIG. 26 is a diagram showing an example of a combination of aircrafts 621 in which the alerting unit 180 in this embodiment alerts the controller.
In this figure, “x” indicates a case where the alerting unit 180 alerts the controller of the aircraft A due to the presence of the aircraft B. “O” indicates a case where the alerting unit 180 does not alert the controller for the aircraft A due to the presence of the aircraft B.
For arriving aircraft "under final approach" indicates the case where a plane distance d is a threshold value D ₁ or more and less than the threshold D ₂ between the starting end 612 of the aircraft 621 and the runway 611. “During landing” indicates a case where the plane distance d is less than the threshold value D ₁ and the distance w between the aircraft 621 and the center line 614 of the runway 611 is less than the threshold value W ₁ .
For the starting motor and cross machine as "entry wait" shows that a distance w between the center line 614 of the aircraft 621 and the runway 611 is lower than the threshold value W ₂ or more and the threshold W _3. “Preparing” for the departure aircraft indicates a case where the distance w is less than the threshold value W ₂ and the speed v of the aircraft 621 is less than the threshold value V ₁ . By "during takeoff" indicates the case where the velocity v of the aircraft 621 is the threshold value V ₁ or d. “Crossing” for the crossing machine indicates a case where the distance w is greater than or equal to the threshold −W ₁ and less than the threshold W ₂ .
“A → B” indicates that the aircraft A is closer to the start end 612 than the aircraft B. Conversely, “B → A” indicates that the aircraft A is closer to the terminal 613 than the aircraft B.

  If the aircraft B is an arrival aircraft and is in the final approach, and if it is a departure aircraft or a crossing aircraft and is waiting to enter, the block generation unit 150 generates an occupied block for the aircraft B, but has already been occupied. Since the block is not generated, the alerting unit 180 does not alert the controller about the aircraft A.

When the aircraft A is closer to the terminal 613 than the aircraft B, and the aircraft B is landing on the arrival aircraft and taking off on the departure aircraft, the block generation unit 150 generates on the terminal 613 side of the aircraft B Since the occupied block and the occupied block of the aircraft A overlap, the alerting unit 180 alerts the controller about the aircraft A.
When the aircraft A is closer to the start end 612 than the aircraft B, and the aircraft B is preparing at the departure aircraft and crossing at the crossing aircraft, the block generation unit 150 is on the start end 612 side of the aircraft B. Since the occupied block generated at the same time and the occupied block of the aircraft A overlap, the alerting unit 180 alerts the controller about the aircraft A.

  When the aircraft A is closer to the start end 612 than the aircraft B, and the aircraft B is landing on the arrival aircraft and taking off on the departure aircraft, the block generation unit 150 moves to the end 613 side of the aircraft B. Generate an occupied block. When the aircraft A is in the final approach or landing at the arrival aircraft and is preparing or taking off at the departure aircraft, the block generation unit 150 generates an occupation block on the terminal 613 side of the aircraft A. In duplicate, the alerting unit 180 alerts the controller about the aircraft A. When the aircraft A is waiting to enter with the departure or crossing aircraft and is crossing with the crossing aircraft, the block generation unit 150 does not generate the occupation blocks on the terminal 613 side of the aircraft A, so the occupation blocks do not overlap, The alerting unit 180 does not alert the controller about the aircraft A.

  When the aircraft A is closer to the end 613 than the aircraft B, and the aircraft B is preparing at the departure aircraft and crossing at the crossing aircraft, the block generation unit 150 is closer to the start end 612 side of the aircraft B. Generate an occupied block. When the aircraft A is preparing on the departure aircraft and crossing on the crossing aircraft, the alerting unit 180 generates an occupied block on the start end 612 side of the aircraft A. Therefore, the occupied blocks overlap and the alerting unit 180 is overlapped. Calls the controller's attention about Aircraft A. When aircraft A is landing on the arrival aircraft, is waiting to enter the departure aircraft or crossing aircraft, and is taking off on the departure aircraft, the alerting unit 180 does not generate an occupied block on the start end 612 side of aircraft A. The occupied blocks do not overlap, and the alerting unit 180 does not alert the controller about the aircraft A.

  In this way, based on the overlapping of the occupied blocks, the alerting unit 180 alerts the controller, and finely sets whether or not to alert the controller by combining the states of the two aircrafts 621. be able to.

The mobile body monitoring device 100 in this embodiment includes a processing device (CPU 911) that processes data, a block generation unit 150, a duplication determination unit 170, and an alerting unit 180.

  According to the mobile object monitoring apparatus 100 in this embodiment, when it is determined whether or not the occupied blocks generated by the block generation unit 150 for a plurality of mobile objects are duplicated, the monitor should be alerted And the case where it is not so can be discriminated appropriately. As a result, the possibility that the monitor overlooks that the plurality of moving bodies have reached the predetermined positional relationship is reduced, and the monitor can make an appropriate situation determination by reducing the duty of care of the monitor. it can.

  In the moving object monitoring apparatus 100 according to this embodiment, the block generation unit 150 uses the processing device to determine the current state of the moving object when the moving object is an aircraft 621 that is running on the runway 611. Assuming that the moving body occupies the area from the position to the end 613 of the runway 611, an occupied block is generated.

  According to the moving body monitoring apparatus 100 in this embodiment, when the moving body is running on the runway 611 for takeoff or landing, a portion corresponding to the moving direction of the moving body in the runway 611 is moved to the moving body. Since it is an occupied block, it is possible to alert the observer when another moving object enters or attempts to enter the area. In addition, the portion of the runway 611 that corresponds to the direction opposite to the moving direction of the moving object is not a block occupied by the moving object, so even if another moving object enters the area, alert the observer. It is possible to allow other mobile objects to enter. Thereby, the use efficiency of the runway 611 can be improved.

  In the moving object monitoring apparatus 100 according to this embodiment, the block generation unit 150 uses the processing device to enter the moving object when the moving object is an aircraft 621 that is about to enter the runway 611. An occupied block is generated on the assumption that the moving body occupies the area on the runway 611 that is about to be occupied.

  According to the moving body monitoring apparatus 100 in this embodiment, when the moving body is going to enter the runway 611, the portion of the runway 611 where the moving body is about to enter is the occupied block of the moving body. Therefore, before the moving body enters the runway 611, it is possible to alert the observer.

  In the moving object monitoring apparatus 100 according to this embodiment, the block generation unit 150 uses the processing device to start the end 612 of the runway 611 when the moving object is the aircraft 621 that has entered the runway 611. To the current position of the moving body, the occupied block is generated assuming that the moving body occupies the area.

  According to the moving body monitoring apparatus 100 in this embodiment, when the moving body enters the runway 611, the other moving bodies of the runway 611 slide in the direction toward the moving body. Since the portion is the occupied block of the moving object, the supervisor can be alerted when there is another moving object that is moving toward the moving object.

In the moving object monitoring apparatus 100 according to this embodiment, the block generation unit 150 uses the processing device as the occupied block, the occupied block representing the area actually occupied by the moving object, and the movement Generate a block to occupy that represents the area the body is going to occupy.
When the duplication determination unit 170 determines that the occupied block for one moving object and the occupied block for another moving object overlap using the processing device, the attention calling unit 180 The above-mentioned observer is alerted to the other moving object.

  According to the mobile object monitoring apparatus 100 in this embodiment, when the occupied blocks of two mobile objects overlap, the two mobile objects are not sympathetically alerted, but the area is occupied first. It is possible to give priority to a moving object and alert the observer about the moving object to be occupied later. Thereby, the supervisor can make a more appropriate situation determination.

The mobile object monitoring device 100 in this embodiment can be realized by a computer having a processing device (CPU 911) for processing data executing a computer program that causes the computer to operate as the mobile object monitoring device 100.
According to the computer program that implements the moving object monitoring apparatus 100 in this embodiment, the occupant's attention is determined by determining whether the occupied blocks generated by the block generation unit 150 for a plurality of moving objects overlap. It is possible to appropriately distinguish between the case where it should be evoked and the case where it should not be. As a result, the possibility that the monitor overlooks that the plurality of moving bodies have reached the predetermined positional relationship is reduced, and the monitor can make an appropriate situation determination by reducing the duty of care of the monitor. A movable mobile monitoring device 100 can be realized.

A moving body monitoring method in which the moving body monitoring apparatus 100 in this embodiment monitors a plurality of moving bodies (aircraft 621) includes the following steps.
The processing device (CPU 911) generates, for each of the plurality of moving objects, an occupied block that represents an area occupied by the moving object.
The processing apparatus determines whether or not a plurality of occupied blocks generated for the plurality of moving objects overlap.
When the processing device determines that the plurality of occupied blocks are overlapping, it alerts the supervisor.

  According to the mobile object monitoring method in this embodiment, by determining whether or not the occupied blocks generated for a plurality of mobile objects are duplicated, it is possible to call the supervisor's attention and not to It can be discriminated appropriately. As a result, the possibility that the monitor overlooks that the plurality of moving bodies have reached the predetermined positional relationship is reduced, and the monitor can make an appropriate situation determination by reducing the duty of care of the monitor. it can.

The moving body monitoring device 100 described above allows the controller to respond to the situation even when aircrafts 621 with different purposes, such as departure aircraft, arrival aircraft, and runway crossing aircraft, request to enter the runway 611 at the same time. Support the controller's decision so that it can make an accurate decision in a short time.
The moving body monitoring device 100 generates, as an occupancy block, a portion that cannot be entered on the runway 611 according to the position of the moving aircraft 621 on the airport ground surface, and uses the generated occupancy block for the runway 611. Monitor occupancy. Another aircraft 621 cannot enter the occupied block. When another aircraft 621 enters the occupied block, the moving object monitoring apparatus 100 determines that the state is the alerting state and provides alerting to the controller.
The moving body monitoring apparatus 100 expands and contracts the size of the occupied block in accordance with the movement of the aircraft 621. For example, when the aircraft 621 is an arrival aircraft, the mobile monitoring device 100 generates an occupied block over the entire runway 611 scheduled to land from a certain time before landing, and another scheduled departure aircraft or runway crossing aircraft enters. The situation is impossible. After the arrival aircraft has landed, the moving object monitoring apparatus 100 reduces the occupied block in accordance with the movement of the aircraft 621. By eliminating the occupied block at the position where the other aircraft 621 is about to enter, the other aircraft 621 can enter the runway 611.

Since the occupied block is generated in accordance with the movement of the aircraft 621, it is possible to systematically determine whether or not the occupied block can be entered.
Since the occupied block is reduced in accordance with the movement of the aircraft 621, the runway 611 can be used efficiently without creating an inaccessible state.
As a result, the controller may perform tasks such as situation judgment for the minimum necessary alert state. In addition, the controller can permit the landing to the runway 611, the takeoff from the runway 611, and the crossing of the runway 611 as much as possible, so that the use of the runway 611 is made more efficient and the number of takeoff and landing aircraft is increased. It becomes possible.

Embodiment 2. FIG.
The second embodiment will be described with reference to FIGS.
In addition, about the part which is common in Embodiment 1, the same code | symbol is attached | subjected and description is abbreviate | omitted.

In this embodiment, a plurality of types are provided for the occupied blocks of the aircraft 621. Depending on the type of the other aircraft 621, the occupied block for determining the overlap with the occupied block of the other aircraft 621 is properly used. For example, the block generation unit 150 generates an occupied block for an arrival aircraft and an occupied block for a departure aircraft for an aircraft 621. When the other aircraft 621 is the arrival aircraft, the overlap determination unit 170 determines the overlap between the occupied block of the other aircraft 621 and the occupied block for the arrival aircraft of the aircraft 621, and the other aircraft 621 is the departure aircraft. If it is, the overlap determination unit 170 determines the overlap between the occupied block of another aircraft 621 and the occupied block for the departure aircraft of the aircraft 621.
Thereby, since the moving body monitoring apparatus 100 can set more finely the classification | category with the case where a controller is alerted and the case where it is not alerted, only when it really needs to alert a controller If the officer's attention is to be raised and the controller's attention needs to be raised, the controller's attention can be definitely raised.

FIG. 27 is a flowchart showing an example of the flow of the arrival unit block generation process S420 in this embodiment.
The arrival machine block generation process S420 includes a partial target block generation process S423 in addition to the processes described in the first embodiment.

In the start distance determination step S421, the block generation unit 150 uses the CPU 911 to determine three threshold values D ₁ , D ₂ , D ₃ (however, 0 based on the block generation rule data stored in the block generation rule storage unit 140) <D ₁ <D ₃ <D _2. ) The block generation unit 150 uses the CPU 911 to compare the calculated plane distance d with the three threshold values D ₁ , D ₂ , and D ₃ .
If the plane distance d is the threshold value D ₂ or terminates the arriving aircraft block generation processing S420.
If the plane distance d is a threshold value _{D 3} or more and less than the threshold value _{D 2,} the process proceeds to occupy scheduled block generating step S422.
If the plane distance d is smaller than the threshold _{D 1} or more and the threshold _{D 3,} the process proceeds to some target block generation step S423.
If the plane distance d is less than 0 or more and the threshold D _1, the process proceeds to all occupied already block generating step S424.
When the plane distance d is less than 0, the process proceeds to the separation distance determination step S426.

  In the partial target block generation step S423, the block generation unit 150 uses the CPU 911 to generate an occupied block that covers only the starting aircraft and the crossing aircraft in the range from the start end 612 to the end 613 of the runway 611. . The block storage unit 160 stores the occupied blocks generated by the block generation unit 150 using the magnetic disk device 920. Thereafter, the arrival machine block generation process S420 is terminated.

FIG. 28 is a diagram illustrating an example of the partial target occupied block 531 generated by the block generation unit 150 in the arrival unit block generation processing S420 in this embodiment.
The partially-occupied block 531 is an occupied block that serves as a basis for the overlap determination for the departure aircraft and the crossing aircraft but does not serve as a basis for the overlap determination for the arrival aircraft.
If the plane distance d between trying to land on the runway 611 and to which the aircraft 621 and the starting end 612 of the runway 611 is less than the threshold value _{D 1} or more and the threshold _{D 3,} the block generator 150, all of the runway 611 A partially-occupied block 531 having a range of is generated.

  Thus, when the aircraft 621 is an arrival aircraft, an intermediate stage is provided between the final approaching state and the landing state. In the intermediate stage, the departure aircraft and the crossing aircraft are excluded from the runway 611, but the arrival aircraft are not excluded. This is because at this time, the arrival aircraft on the runway 611 is another aircraft 621 that has landed on the runway 611 before the aircraft 621, so that it can be expected to immediately leave the runway 611. Accordingly, the landing interval of the aircraft 621 can be shortened while preventing another aircraft 621 from entering the runway 611, so that the utilization efficiency of the runway 611 can be increased.

FIG. 29 is a flowchart showing an example of a flow of the crossing machine block generation processing S440 in this embodiment.
The crossing block generation process S440 includes a partial target block generation process S444 instead of the rear occupied block generation process S443 described in the first embodiment.

If the distance w between the aircraft 621 and the center line 614 of the runway 611 is greater than or equal to the threshold −W ₁ and less than the threshold W _{2 in the} approach distance determination step S441, the process proceeds to a partial target block generation step S444.

  In the partial target block generation step S444, the block generation unit 150 uses the CPU 911 to acquire the current position of the aircraft 621 based on the moving body data acquired in the state determination step S410. The block generation unit 150 uses the CPU 911 to generate an occupied block that covers only the arrival aircraft and the departure aircraft in the range from the starting end 612 of the runway 611 to the acquired current position of the aircraft 621. The block storage unit 160 uses the magnetic disk device 920 to store the generated occupied block. Thereafter, the crossing block generation process S440 is terminated.

FIG. 30 is a diagram illustrating an example of the partial target occupied block 534 generated by the block generation unit 150 in the arrival unit block generation processing S420 in this embodiment.
The partially-occupied block 534 is an occupied block that serves as a basis for the overlap determination for the arrival aircraft and the departure aircraft, but does not serve as a basis for the overlap determination for the crossing aircraft.
When the distance d between the aircraft 621 about to cross the runway 611 and the center line 614 of the runway 611 is greater than or equal to the threshold −W ₁ and less than the threshold W ₂ , the block generation unit 150 performs the runway 611. A partially-occupied block 534 is generated in a range from the starting end 612 to the current position of the aircraft 621. As a result, the arrival aircraft and the departure aircraft are excluded from the start end 612 side of the aircraft 621, but the crossing aircraft is not excluded. Accordingly, multiple aircraft 621 can cross the same runway 611 simultaneously.

  Next, the overlap determination processing S450 will be described with reference to FIG.

In the occupied block selection step S452, the duplication determination unit 170 uses the CPU 911 to select the occupied blocks of the aircraft 621 other than the aircraft 621 selected in the moving object selection step S451 from the occupied blocks stored in the block storage unit 160. Then, the occupied blocks including the type of the aircraft 621 selected in the moving body selection step S451 are selected one by one.
For example, if the aircraft 621 selected in the moving body selection step S451 is an arrival aircraft, the duplication determination unit 170 selects an occupied block that does not limit the target from among the occupied blocks stored in the block storage unit 160. The partial target occupied block that includes the arrival aircraft is selected, but the partial target occupied block that does not include the arrival aircraft is not selected.

  Accordingly, when the occupied block of the aircraft 621 overlaps with the occupied block of another aircraft 621 that does not limit the target or the partially targeted occupied block of another aircraft 621 that includes the type of the aircraft 621, The alerting unit 180 alerts the controller about the aircraft 621.

FIG. 31 is a diagram illustrating an example of a combination of aircrafts 621 in which the alerting unit 180 in this embodiment alerts the controller.
For arriving aircraft "under final approach" is the plane distance d between the starting end 612 of the aircraft 621 and the runway 611 shows the case of a threshold value D ₃ or more and less than the threshold D _2. The "intermediate stage" indicates the case where the plane distance d is less than the threshold D ₁ or more and the threshold D _2.

  When the aircraft B is an arriving aircraft and is in an intermediate stage, the block generation unit 150 generates an occupied block for the departure aircraft and the crossing aircraft for the aircraft B, so that the aircraft A is a departure aircraft or a crossing aircraft. For example, the alerting unit 180 alerts the controller about the aircraft A. If the aircraft A is an arrival aircraft, the alerting unit 180 does not alert the controller about the aircraft A.

  When the aircraft B is a crossing aircraft and is crossing, the block generation unit 150 generates an occupied block for the arrival aircraft and the departure aircraft for the aircraft B. The awakening unit 180 does not alert the controller about the aircraft A.

  In this way, by changing the occupied block for determining overlap according to the type of the aircraft 621, whether or not to alert the controller can be set more appropriately.

In the moving object monitoring apparatus 100 in this embodiment, the block generation unit 150 uses the processing device (CPU 911) to generate occupied blocks representing different areas for each type of other moving object (aircraft 621). .
If the occupancy block for another moving body and the occupancy block for the type of the other moving body overlap for one moving body using the processing device, the duplication determination unit 180 When 170 judges, it alerts the said monitor about said other moving body.

  According to the mobile object monitoring apparatus 100 in this embodiment, different occupancy blocks are generated depending on the type of other mobile object that is a partner to be alerted, so that detailed settings according to the type of mobile object are made. And, more appropriately, alert the observer.

  According to the mobile monitoring apparatus 100 described above, fine monitoring can be performed by providing added value to the occupied block such as setting of the monitoring target of the occupied block.

  The mobile body monitoring device 100 inputs aircraft data (mobile body data). The aircraft data holds the flight name, position, altitude, speed, and the like of the aircraft 621. The moving body monitoring apparatus 100 determines whether the aircraft 621 is a departure aircraft, an arrival aircraft, or a runway crossing aircraft based on the aircraft data. The mobile monitoring apparatus 100 generates block information (occupied block) according to the position of the aircraft 621, and adds a block target to be monitored to the generated block information. The moving body monitoring apparatus 100 realizes monitoring of the aircraft 621 on the runway 611 by monitoring the overlap of the block information based on the generated block information. The block information is, for example, a set of a numerical value representing the start point of the occupied block and a numerical value representing the end point depending on the distance from the start end 612, regarding the runway 611 as a one-dimensional line segment.

For the arrival aircraft, the status is defined as follows according to the distance d from the start end 612 of the runway 611 scheduled to land. The mobile monitoring apparatus 100 determines a block range on the runway 611 and an aircraft 621 to be blocked according to the status.
-During the final approach: When the distance d from the start end 612 of the runway 611 being approached is a certain value (threshold value D ₃ ) or more. The block range is the entire runway 611. There is no block target.
· Runway occupancy (intermediate stage): If the distance d from the starting end 612 of the runway 611 in approach are apart a predetermined value (threshold value D ₁₎ or more. The block range is the entire runway 611. Blocks are departure aircraft and runway crossing aircraft.
Landing state (landing): When the distance d from the start end 612 of the approaching runway 611 is less than a certain value (threshold value D ₁ ). The block range is the entire runway 611. Block types are all types.
Landing state (landing): When the arrival aircraft is on the runway 611. The block range is from the position of the arrival aircraft to the end 613 of the runway 611. Block types are all types.
When the distance w between the arrival aircraft and the center line 614 of the runway 611 exceeds a certain value (threshold value W ₁ ), the moving object monitoring apparatus 100 determines that the vehicle has left the runway 611 and deletes the occupied block. To do.
The threshold values D ₁ , D ₃ , W ₁ can be arbitrarily set as parameters. Similarly, the block target can be arbitrarily set as a parameter.

For the departure aircraft, the status is defined as follows according to the distance w from the runway 611 scheduled to take off, the approach state to the runway 611, and the like. The mobile monitoring apparatus 100 determines a block range on the runway 611 and an aircraft 621 to be blocked according to the status.
Runway pre-occupied state (waiting for approach): When the distance w from the intersection with the taxiway adjacent to the runway 611 scheduled to take off is equal to or greater than a certain value (threshold value W ₂ ). The block range is around the intersection. There is no block target.
-Runway occupation state (in preparation): When the departure aircraft exists on the runway 611. The block range is from the start 612 of the runway 611 to the position of the departure machine. Block types are all types.
-Takeoff run state (during takeoff): When the departure aircraft exists on the runway 611, the speed v is equal to or greater than a certain value (threshold value V ₁ ), and the acceleration a is equal to or greater than a certain value. The block range is from the position of the departure machine to the end 613 of the runway 611. Block types are all types.
When the distance w between the departure aircraft and the center line 614 of the runway 611 exceeds a certain value (threshold value W ₁ ), the moving body monitoring device 100 suspends takeoff and leaves the runway 611. Is determined, and the occupied block is erased.
The threshold values W ₁ and W ₂ can be arbitrarily set as parameters. Similarly, the block target can be arbitrarily set as a parameter.

Regarding the runway crossing machine, the status is defined as follows according to the distance w from the runway crossing location of the runway 611 to be crossed, the approach state to the runway 611, and the like. The mobile monitoring apparatus 100 determines a block range on the runway 611 and an aircraft 621 to be blocked according to the status.
State before crossing the runway (waiting for approach): When the minimum distance w between the position of the candidate aircraft 621 crossing the runway 611 and the runway 611 is within a certain value (threshold value W ₃ ). The block range is the planned crossing part (guidance width). Blocks are departure aircraft and runway crossing aircraft.
-Runway crossing state (crossing): When the minimum distance w between the position of the candidate aircraft 621 crossing the runway 611 and the runway 611 is within a certain value (threshold value W ₂ ). The block range is from the start 612 of the runway 611 to the position where the aircraft 621 entered. Block targets are departure and arrival aircraft.
When the minimum distance w between the position of the crossing machine and the runway 611 is equal to or greater than a certain value (threshold value W ₁ ), the moving object monitoring apparatus 100 determines that the crossing has ended and deletes the occupied block.
The threshold values W ₁ , W ₂ and W ₃ can be arbitrarily set as parameters. Similarly, the block target can be arbitrarily set as a parameter.

  Based on the occupancy block (block range and block target) generated as described above and the status (arrival aircraft, departure aircraft, or runway crossing aircraft) of each aircraft 621, the mobile monitoring device 100 occupies the runway. Monitor. When the occupied block of the aircraft 621 overlaps with the occupied block of the other aircraft 621 and the block target of the occupied block of the other aircraft 621 matches the aircraft 621, the moving object monitoring apparatus 100 matches the aircraft 621. It is determined that the state is an alert state, and alert information is provided to the controller.

For example, if there are arrival aircraft in the final approach and departure aircraft in the runway occupation state, the block range (entire range) of the occupation block of the arrival aircraft and the block range (starting end 612 side) of the occupation block of the departure aircraft Are overlapping. Since the departure target is not included in the block target (none) of the occupancy block of the arrival aircraft, the moving object monitoring apparatus 100 determines that the state is not an alert state for the departure aircraft. In addition, since the arrival target is included in the block targets (all types) of the occupied block of the departure aircraft, the moving object monitoring apparatus 100 determines that the state is an alerting state for the arrival aircraft.
Thereafter, when the arrival aircraft approaches the runway 611 and becomes the runway occupation state, the block range does not change, and the block target of the occupied block of the arrival aircraft changes to the departure aircraft or the runway crossing machine. It is determined that the departure aircraft has been alerted.

Also, for example, if there is a runway occupying state (waiting for takeoff) and a runway crossing machine in a state before the runway crossing that is going to cross the terminal 613 side more than that, Since the block range (starting end 612 side) does not overlap with the block range (scheduled crossing portion) of the occupied block of the runway crossing machine, the moving object monitoring apparatus 100 determines that the state is not an alert state.
After that, when the runway crossing machine enters the runway 611 and enters the state of crossing the runway, the block range of the occupied block of the runway crossing machine changes to the start end 612 side, and the block ranges overlap. Since the block target (all types) of the occupied block of the departure aircraft includes the runway crossing machine, the moving object monitoring apparatus 100 determines that the state is an alert state for the runway crossing machine. Moreover, since the departure object is included in the block target (arrival aircraft or departure aircraft) of the occupation block of the runway crossing machine, the moving object monitoring apparatus 100 determines that the departure aircraft is also in an alert state.

  Further, for example, when there are an arrival aircraft A in the runway occupation state and an arrival aircraft B in the landing state, the block range (entire range) of the occupation block of the arrival aircraft A and the block range of the occupation block of the arrival aircraft B ( The end 613 side). Since the arrival target is not included in the block target (departure machine or runway crossing machine) of the occupancy block of the arrival machine A, the moving object monitoring apparatus 100 determines that it is not in the alert state for the arrival machine B. Moreover, since the arrival target is included in the block objects (all types) of the occupied block of the arrival aircraft B, the mobile monitoring device 100 determines that the arrival aircraft A is in an alert state.

As described above, by making it possible to set the block target with parameters, it is possible to suppress the alerting to the minimum necessary. For example, if the preceding landing aircraft is in the landing state (landing state) on the runway 611 and the subsequent aircraft approaches the runway 611, the mobile object monitoring device 100 does not alert the controller, so It does not occur and the load on the controller can be reduced.
In addition, it is possible to minimize warnings by generating occupancy blocks flexibly according to the position and state of arrival aircraft, departure aircraft, and runway crossing aircraft. Furthermore, by making the block range settable by parameters, it becomes possible to set the block range according to the controller's business method. As a result, alerting can be minimized, and by supporting the controller, the number of takeoffs from the runway 611, the number of landings on the runway 611, and the number of crossings of the runway 611 can be maximized. The utilization efficiency of the runway 611 can be increased.
