Description

  The present invention relates to control of a control display system placed in a control station such as an aircraft.

  Conventionally, in the status display of a control device that monitors a flying object such as an aircraft, viewpoint control such as setting of a display range and a display center position has been manually performed by an operator. In the above control display system, the alert generated when the target mode changes is displayed with a fixed priority for each type of alert. Alert messages with the same priority are displayed in the order of alert occurrence.

JP 2002-24862 A

In the above conventional control device, the display range and the display mode are not individually changed for each flying object. For example, a flying object with a high degree of attention and a flying object with a low degree of attention are displayed uniformly. Therefore, it was difficult for the observer watching the situation display screen to distinguish the flying object with a high degree of attention from the other.
In addition, even if a high-attention alert that needs to be recognized quickly by the observer, the alert was displayed in the order of alert occurrence based on only a fixed priority, so that a high-profile flying object is I couldn't figure out alerts with higher priority than others.

The present invention has been made to solve the above problems, and provides a control display system, a control display method, and a control display program capable of causing an appropriate display mode according to the degree of attention of a monitoring target. Objective.
Furthermore, another object of the present invention is to provide a control display system, a control display method, and a control display program capable of rearranging and displaying the order of alerts in descending order of importance.

In order to solve the above problems, the present invention employs the following means.
In the reference example of the present invention , information acquisition means for acquiring a target to be monitored and attribute information of the target, and viewpoint control conditions that are information on the target attribute information and the display mode of the target are preliminarily set. Control condition storage means stored in association with each other, and attribute information matching the target attribute information acquired by the information acquisition means is detected from the control condition storage means, and is associated with the detected attribute information. Viewpoint control means for extracting the viewpoint control conditions, and display means for displaying a result of the target viewpoint control based on the viewpoint control conditions extracted by the viewpoint control means. A control display system is provided.

According to the reference example of the present invention , when a target to be monitored is detected, a viewpoint control condition corresponding to the target attribute information is extracted from the control condition storage unit, and the viewpoint control condition is determined. A screen subjected to viewpoint control is displayed on the display means. Therefore, the display mode can be varied according to the target attribute information. Thus, for example, by defining viewpoint control conditions suitable for the movement status and type of the target, the target is displayed on the display means in an appropriate display mode according to the movement status and type. It becomes possible to make it. For example, for a target with a high degree of attention, in other words, for a target with a high degree of urgency, by defining a condition of viewpoint control that displays the movement of the target in detail, the degree of attention of the target and the degree of urgency Etc. can be recognized.
The target attribute information includes at least one of information related to the movement of the target and information related to the type of the target.

  The control display system includes information comparison means for comparing the attribute information of the target acquired from the information acquisition means with the attribute information of the target in the past, and comparing whether or not the attribute information has changed. When the attribute information is changed, the viewpoint control unit may extract the viewpoint control condition.

  Thus, since the information comparison means for comparing the current attribute information of the target with the past attribute information is provided, it can be determined whether or not the target has moved. Thereby, it is possible to perform viewpoint control corresponding to the movement only on the moved target or the like. As a result, it is possible to notify the supervisor of the approaching state of the target.

  In the control display system, the target attribute information may be set in multiple stages in the viewpoint control condition storage unit.

  In this way, by setting the target attribute information in multiple stages, for example, it is possible to set appropriate viewpoint control conditions respectively corresponding to the detailed attribute information of the target type and movement status. As a result, fine viewpoint control according to target attribute information can be performed.

Storing present invention, an information acquisition means for acquiring the attribute information of the target and the target to be monitored, and the attribute information of the target, the alert priority level is the order of the alert messages and is associated with and alert priority storage means being, and alert generating means for generating the alert message including a fixed priority information uniquely determined on the attribute information and the target of the target, before Symbol goal of the alert message The alert priority obtained by detecting attribute information matching the attribute information from the alert priority storage means, extracting the alert priority associated with the detected attribute information, and extracting the fixed priority of the alert message by comprising the alert control means for changing, and display means for displaying an alert message based on the alert priority issued extracted in Providing control display system characterized.

  According to the present invention, for example, when the detected object approaches within a certain range, an alert message is generated, and the alert message is rearranged based on the priority in the alert message. Alerts with a high degree of importance such that the target target is approaching the neighborhood can be displayed higher than other alert messages. This makes it easier for the monitor to find important alert messages, and allows the monitor to recognize alerts with a higher degree of urgency.

  The control display system may display the number of messages that are not displayed in addition to the alert message displayed by the alert display means.

  In this way, when there is an alert message other than the alert message currently displayed by the alert display means, the current alert message can be displayed and the number of remaining alert messages can be displayed on the screen. The monitor can grasp the occurrence status of the alert message.

  According to the present invention, the first process of acquiring the target to be monitored and the attribute information of the target is associated in advance with the target attribute information and the viewpoint control condition that is information relating to the display mode of the target. A second process of detecting attribute information that matches the target attribute information acquired in the first process, and extracting a viewpoint control condition associated with the detected attribute information; And a third process of displaying a result of the target viewpoint control extracted based on the viewpoint control conditions extracted in two processes.

  Embodiments of a control display system, method, and control control program according to the present invention will be described below with reference to the drawings in the order of [first embodiment] and [second embodiment].

[First Embodiment]
FIG. 1 is a functional block diagram showing a schematic configuration of a control display system according to the present embodiment.
As shown in FIG. 1, the control display system 10 according to the present embodiment includes an information acquisition unit (information acquisition unit) 1, a target database 2, a control condition storage unit (control condition storage unit) 3, and a viewpoint control unit (viewpoint). A control unit 4, a status display client unit 5, a display unit (display unit) 9, and an information comparison unit (information comparison unit) 11 are provided as main components.

  In the control display system 10, the information acquisition unit 1 targets an object automatically input by an operator or automatically input by radar detection, assigns a target number that is an identification number unique to the target, and sets the target type, course Get attribute information such as speed, position. The target number and target attribute information are output to the information comparison unit 11. Specifically, when the target input by the operator is a flying object, the information acquisition unit 1 sets the target number of the flying object as 100, and acquires attribute information such as the position speed and position information of the target number 100. The attribute information associated with the target number 100 is output to the information comparison unit 11.

The information comparison unit 11 acquires the past attribute information of the target number input from the information acquisition unit 1 from the target database 2 and compares them, thereby comparing the attribute information of the target number input from the information acquisition unit 1 It is determined whether or not has changed. As a result of this determination, if there is a change in the attribute information, for example, if a target has been newly added, or if the target has moved, this target number is output to the viewpoint control unit 4 The attribute information input from the information acquisition unit 1 is stored in the target database 2 in association with the target number. On the other hand, if the attribute information has not changed as a result of the determination, the attribute information and the target number are associated with each other and stored in the target database 2 without outputting the target number to the viewpoint control unit 4.
As a result, the target database 2 stores the attribute information history acquired by the information acquisition unit 1 in association with each target number.

  The control condition storage unit 3 stores target attribute information and viewpoint control conditions in association with each other. Specifically, a condition is stored so that when the attention level of the target is higher than others as judged from the attribute information, the display mode of the target is different from others. For example, the attribute information that “the target type is an aircraft and the distance from the point A is within a certain range” includes a viewpoint such as “the display center is the point A and the display range is 70 km”. Control conditions are associated. FIG. 2 is an example of definitions of viewpoint control conditions stored in the control condition storage unit 3. The viewpoint control condition can be set by combining a plurality of conditions such as target attribute information (in multiple stages).

  In FIG. 2, “the center of the status display is set to the target position” only when the condition of the target type is aircraft, the nationality of the target is other than Japan, and the target altitude is 3000 feet or less. It shows that the viewpoint is controlled. In this way, since a plurality of conditions can be combined, when there is a change in an important aspect that the monitor should pay particular attention to, the viewpoint can be controlled and an important change in the aspect can be displayed to the monitor. it can. If the viewpoint control conditions cannot be set in multiple stages and there are a large number of aircraft, a plurality of targets coincide with the viewpoint control conditions. As a result, the viewpoint of the display screen is frequently switched, and the display screen becomes difficult for the observer. For this reason, setting viewpoint control conditions in multiple stages is effective for making the supervisor recognize the target. The definition of multi-stage viewpoint control conditions is described in XML, for example.

  When the target number is input from the information comparison unit 11, the viewpoint control unit 4 reads the latest attribute information associated with the target number from the target database 2. Subsequently, attribute information that matches the read attribute information is detected from the control condition storage unit 3, and a viewpoint control condition associated with the detected attribute information is extracted. Then, the viewpoint control unit 4 outputs the extracted viewpoint control conditions to the status display client unit 5.

  Specifically, when acquiring the notification of the target number 100 from the information comparison unit 11, the viewpoint control unit 4 reads the attribute information associated with the target number 100 from the target database 2. At this time, for example, when “flying object” is registered as the target type and position information is registered as the predicted landing position, is attribute information matching this attribute information registered in the control condition storage unit 3? Determine whether or not. As a result, for example, when there is attribute information that “the target type is a flying object and the expected landing position has been found”, the control condition storage unit sets the viewpoint control condition associated with this attribute information. 3 and outputs the viewpoint control condition to the status display client unit 5.

The status display client unit 5 performs processing for switching viewpoint display based on the viewpoint control condition acquired from the viewpoint control unit 4, and outputs the processed result to the display unit 9.
For example, when information on the viewpoint control condition “moving the viewpoint angle from left to right” is input, such viewpoint control processing is performed on the screen display of the control device, and the result is displayed. To the unit 9.

Next, the operation of the control display system according to the present embodiment will be described with reference to FIG.
When information of an object input by a monitor or detected by a radar or the like is input to the information acquisition unit 1, a target number is assigned to the object in the information acquisition unit 1, and the target type, course, Attribute information such as speed and position is output to the information comparison means 11 in association with the target number. In the information comparison unit 11, past (for example, previous) attribute information of the target number input from the information acquisition unit 1 is read from the target database 2 and stored in the target database 2 with the latest attribute information input this time. The past attribute information that has been stored is compared (step SA1 in FIG. 3).

  If the attribute information is different as a result of the comparison, the target number is notified to the viewpoint control unit 4, and the viewpoint control unit 4 notifies the target number whose attribute information has changed (step SA2). On the other hand, if the attribute results are not different as a result of the comparison, step SA1 is repeated. Subsequently, the viewpoint control unit 4 compares the attribute information that matches the attribute information read from the target database 2 in the control condition storage unit 3 (step SA3). As a result of the comparison, if it is determined that the attribute information matching the attribute information read from the target database 2 is in the control condition storage unit 3, the viewpoint control condition associated with the attribute information is extracted. Then, the extracted viewpoint control conditions are output to the status display client unit 5, and processing for switching the viewpoint display based on the viewpoint control conditions is performed (step SA4). The screen result subjected to the viewpoint control is output to the display unit 5 of the control display system (step SA5), and then this process ends. As a result of the comparison, if it is determined that there is no matching attribute information in the control condition storage unit 3, the present process is terminated without doing anything.

  An example of viewpoint control is shown in FIGS. For example, as shown in FIG. 4, when a screen in which a target flies is displayed from the front of the screen, the target is switched to a screen in which the target appears to fly from the right side to the left side of the screen. When the viewpoint control condition is input to the situation display client unit 5, the situation display client unit 5 creates a screen so that the target flies from the right side to the left side as shown in FIG. It is displayed on the display unit 9. As a result, the target display screen is switched from FIG. 4 to FIG. 5.

  As described above, according to the control display system according to the present embodiment, the viewpoint control of the control display system is performed according to the change in the detected target state such as the target type, the target course, the speed, and the position. Do. When performing viewpoint control, multiple conditions for controlling the display center position, display range, etc. are registered depending on the situation, so the situation in which the moving object is approaching the neighborhood is imminent. When this occurs, the viewpoint of the status display can be automatically changed based on these conditions. Thereby, it becomes possible to make the supervisor of the control device recognize the target degree of urgency.

  In the present embodiment, the target attribute information acquired by the information acquisition unit 1 is compared with the previous target attribute information, and the viewpoint control unit 4 is notified only when the attribute information is different. However, it is not limited to this. For example, the target attribute information acquired by the information acquisition unit 1 may be directly notified to the viewpoint control unit 4 as it is without comparing the target attribute information with the previous attribute information.

  In this embodiment, viewpoint control conditions are stored in advance in the control condition storage unit. However, this condition may allow a supervisor of the control display system to change a predetermined viewpoint control condition. However, it is good also as a monitoring person inputting manually. Such a setting can be arbitrarily performed by the user.

  In the example of the viewpoint control condition in the present embodiment, the condition is narrowed down using the logical product “AND”, but the present invention is not limited to this. For example, a condition can be defined using a logical “or” that matches more conditions. Specifically, the viewpoint control may be performed when a target such as an aircraft does not exist at all and a certain target is detected.

  In the present embodiment, the target object is a moving object, but the present invention is not limited to this. For example, an object that has not moved may be targeted.

[Second Embodiment]
Next, a second embodiment of the present invention will be described with reference to FIG.
As shown in FIG. 6, the control display system of the present embodiment is different from the first embodiment in that alert information is generated instead of the viewpoint control unit, control condition storage unit, and status display client unit. Alert generation unit (alert generation unit) 6, alert priority storage unit (alert priority storage unit) 7 storing alert priority associated with target attribute information, and target attribute information An alert control unit (alert control means) 8 that determines the display order of alerts according to the priority of alerts, an alert display client unit 12 that displays alert messages, and an undisplayed alert message database 13 are provided. . Hereinafter, the control display system of the present embodiment will not be described with respect to the points common to the first embodiment, and different points will be mainly described.

The alert generation unit 6 receives a target number from the information comparison unit 11 and information indicating a target state. When the target number is input, the alert generation unit 6 assigns a fixed priority uniquely determined to the target, and generates an alert message including the priority based on the target state. The alert message is a notification that informs the supervisor of the target state, and includes information on the target number, the target state, and the priority. Here, the priority given to the target information is set higher than the priority given to the system side described later. The alert priority indicates the priority in the case of displaying an alert. The smaller the priority value, the higher the priority.
The alert message is generated, for example, as “target number 100 priority: medium“ detect target of target number 100 ””. When a new target is detected, the distance from a certain point is within a certain range. There are alert messages according to multiple situations.

In addition, information indicating that a system error has occurred is input to the alert generator 6 from the system side. When such information is input, the alert generator 6 gives a fixed priority uniquely determined for the system error and generates an alert message including the priority.
The alert message generated in this way is output to the alert control unit 8.

When the alert control unit 8 acquires the alert message from the alert generation unit 6, the alert control unit 8 reads the latest attribute information associated with the target number from the target database 2. Subsequently, the attribute information that matches the read attribute information is detected, and the alert priority associated with the detected attribute information is extracted from the alert priority storage unit 7 (details will be described later). Then, the alert control unit 8 changes the priority of the alert message to the extracted alert priority, rearranges the display order of the alert messages that have already been generated but are not displayed, and stores them in the undisplayed alert message database 13. Store. The alert display client unit 12 outputs the alert message having the highest priority and the number of undisplayed alert messages to the display unit 9 according to the alert update instruction of the supervisor.

  Specifically, the alert control unit 8 reads the attribute information associated with the target number 100 from the target database 2 when acquiring the alert message notification of the target number 100 from the alert generating unit 6. At this time, for example, when “flying object” is registered as the target type and position information is registered as the predicted landing position, attribute information that matches the attribute information is registered in the alert priority storage unit 7. It is determined whether or not. As a result, for example, if there is attribute information that “the target type is a flying object and the expected landing position has been found” and the alert priority at that time is set to 1 (highest), The priority of the alert message is changed to alert priority 1 set in the alert priority storage unit 7. Then, alert messages that have already been generated but are not displayed are read from the undisplayed alert message database 13, the display order of the alerts is rearranged in descending order of alert priority, and stored in the undisplayed alert message database 13. The alert display client unit 12 outputs the alert message having the highest priority and the number of undisplayed alert messages to the display unit 9 according to the alert update instruction of the supervisor.

  The alert priority storage unit 7 stores target attribute information and alert priority in association with each other. Specifically, alert priority is given and stored on condition of attribute information such as target type, altitude, arrival position, speed, direction, and the like. For example, when the target attribute information is “the target type is a flying object and the predicted landing position is known”, information that sets the priority to 1 (highest) is stored. In addition, alert priority such as 2 (normal) is stored in the target attribute information “type of target is unknown”. FIG. 7 is an example of the definition of alert priority stored in the alert priority storage unit 7. For example, such a definition is described in XML or the like.

Next, the operation of the control display system according to the present embodiment will be described with reference to FIGS. FIG. 8 is an operational flow for generating a hidden alert database based on the alert priority based on the generated alert.
When the information input by the observer and the information of the object detected by the radar is input to the information acquisition unit 1, the information acquisition unit 1 assigns a target number to the object, and sets the target type, course, Attribute information such as speed and position is output to the information comparison means 11 in association with the target number. In the information comparison unit 11, the past (for example, previous) attribute information of the target acquired from the information acquisition unit 1 is read from the target database 2 and stored in the target database 2 with the latest attribute information input this time. The past attribute information is compared (step SB1 in FIG. 8).

If the attribute information is different as a result of the comparison, the target number or the like is notified to the alert generation unit 6, and the alert generation unit 6 generates an alert message of the target number. The generated alert message is output to the alert control unit 8. The alert control unit 8 reads the attribute information associated with the corresponding target number from the target database 2 (step SB2). On the other hand, if the attribute information is not different as a result of the comparison, step SB1 is repeated.

  Subsequently, target attribute information associated with the target number that matches the extracted target number is extracted from the target database 2 (step SB3). Furthermore, it is determined whether or not the attribute information corresponding to the alert priority control condition that matches the extracted target attribute information exists in the alert priority storage means (step SB4). As a result of the determination, there is matching attribute information. In this case, the alert priority read from the alert priority storage unit 7 is given. (Step SB5) On the other hand, if there is no matching attribute information as a result of the determination, the fixed alert priority assigned by the alert generation unit 6 is left unchanged, and the priority is not changed (Step SB6). Next, from the hidden alert message database 13, the number of the hidden alert messages and the number of the hidden alert messages is read out, including the new alert messages, sorted in descending order of the alert priority, and the number of the hidden alert messages is increased by 1, This is stored in the undisplayed alert message database 13 (step SB7), and this process is terminated.

  Next, an operation flow for displaying an alert message will be described with reference to FIG. When an undisplayed alert message is generated, the alert display client unit 12 displays the number of undisplayed messages on the display unit 9 (step SC1 in FIG. 9). It is determined whether or not there is a display update instruction request from the monitor (step SC2). If there is no request, nothing is done and the process returns to the beginning. If there is a request, the alert messages are read from the undisplayed alert message database 13 arranged in descending order of alert priority, and displayed on the display unit 9 (step SC3). Further, the number of undisplayed alert messages is reduced by 1 and displayed on the display unit 9, and the number of undisplayed alert messages is stored in the undisplayed alert database 13 (step SC4). It is determined whether or not all undisplayed alert messages have been displayed. If all are displayed, this processing is terminated. If an undisplayed message remains, the process returns to the beginning (step SC5).

  As described above, according to the control display system according to the present embodiment, the order in which the alert messages are displayed is determined according to the content of the alert, and the alert message having a high priority is preferentially displayed. It becomes possible to rearrange. This makes it possible for the supervisor of the control display system to easily recognize an alert message with a high degree of urgency such as a dynamic object approaching the vicinity.

  In the present embodiment, the target attribute information acquired by the information acquisition unit 1 is compared with the previous target attribute information, and the alert generation unit 6 is notified only when the attribute information is different. However, it is not limited to this. For example, all the target attribute information acquired by the information acquisition unit 1 may be directly notified to the alert generation unit 6 without comparing the target attribute information with the previous attribute information.

  In this embodiment, the alert priority storage unit stores the alert priority in advance. However, this priority may be changed by the monitor of the control display system, or the monitor may manually change the priority. It is good also as inputting with. Such a setting can be arbitrarily performed by the user.
