- supervision systems described below include one or more display screens adapted to display a business plan in part or in its entirety.
- a supervision system for viewing temporally one or more operations (hereinafter activities) to achieve vis-à-vis a device under supervision.
- activities can be carried out by human operators or by computerized systems.
- devices under supervision such as satellites (eg telecommunications satellites, observation satellites) some of whose activities are generally managed in satellite control centers.
- telecommunications satellites that are geostationary are controlled in real time on the ground by operators to perform activities such as repositioning the satellite in its orbit and controlling its various devices (eg batteries, tanks).
- Some of these activities are carried out by computerized systems such as sending commands to the satellite or recovering measurements from the satellite on the ground.
- Other activities are carried out by humans such as, for example, calculating the trajectory of the satellite (ie evolution over time of the position of the satellite) in order to perform for example a "nozzle firing" to correct the position of the satellite .
- the present invention can be applied more broadly to any industrial system comprising devices under supervision (e.g., supervision of industrial processes, supervision of factories, etc.).
- FIG. 1 there is shown a prior art supervision system 100 comprising the visualization of a business plan and comprising:
- the activities 101 to be carried out as a function of time are planned by the scheduler 103 which thus generates a business plan 104.
- the scheduler 103 is often based on a planning software capable of positioning in the business plan 104 activities 101 while taking into account constraints 102 which may be time constraints but also constraints of available resources, as indicated above.
- constraints 102 which may be time constraints but also constraints of available resources, as indicated above.
- the business plan execution engine 105 is able to execute at the scheduled time by the scheduler 103 each of the scheduled tasks.
- the execution engine 105 is also able to control various applications, especially when the activities are fully automated.
- the activity plan display device 106 coupled to the execution engine 105 is able to visually represent the activity plan in a display screen, often in real time.
- FIG. 2 there is shown such a display window 1 in which three activities A-1, A-2 and A-3 are represented with A-1 preceding A-2 and A-2 preceding A-3.
- the time is also represented as well as a progress bar 1 1 1 indicating the current time and making it possible to determine which activity is being executed by the execution engine 105.
- activity A-1 is running and activities A-2 and A-3 have not yet been performed.
- the business plan 104 is shown in FIG. 2 in the form of a Gantt chart. Nevertheless, a representation in the form of a table is also common. More generally, the visual representations of activities over time can be likened to an acyclic oriented graph of the activities to be performed, represented temporally. But if the visualization of activities over time is an indispensable element of supervision, one of the main technical limitations of this approach is that it appears rather difficult to represent a business plan 104 incorporating alternatives for which the operator is led to take one or more decisions. For example, in FIG. 3A it is represented in the viewing window 1 10, a business plan 104 incorporating a conditional choice 1 12. Thus in FIG. 3A, when activity A-2 is complete, the operator must decide whether:
- the progress bar of the current time 1 1 1 can not indicate that an iterative loopback is in progress.
- the iteration loop 1 13 can be executed several times according to the circumstances, it is very difficult to know if the iteration loop 1 13 is executed and / or at which iteration it is find.
- the current time progress bar 11 may be at activity A-3, indicating that activity A-3 is executed, while perhaps the iteration loop 1 13 is running. As we can see again, this representation is quite ambiguous and even misleading for a supervisor.
- an activity belongs to one of the following two categories of tasks, of different granularity:
- steps - low-level tasks that are more refined than high-level tasks
- an activity can be associated with one or more steps.
- the activities i.e. high-level tasks required for this maneuver can be presented as follows:
- the activity (c) can be associated with the following steps (i.e. low level tasks):
- Steps (1) and (2) can be performed by a computer system while steps (3) and (4) are manual.
- the transition from a current activity to the subsequent activity is in particular as a function of time, that is to say by time constraint (so-called precedence). Nevertheless, resource constraints can also be taken into consideration.
- the transition from a current step to the subsequent step is done according to at least one predefined passage rule that does not depend on time. For example, a passing rule may depend on the value of certain parameters, logic elements, and / or the operator's opinion.
- a display system 200 adapted to visualize in time, a business plan, comprising:
- the scheduler 204 is configured to obtain a business plan 205 and a step plan 206 from at least one activity 201 and a time constraint 203.
- the constraint 203 may further depend on available resource (s), for example at the satellite or ground control equipment.
- the scheduler 204 is configured to obtain the activity plans 205 and steps 206 from activities 201 and steps 202 in addition to the constraint 203.
- the activities 201, steps 202 and constraints 203 may be provided as one or more files. For example, one or more text or XML files may be used to define the activities 201, the steps 202 and / or the constraints 203.
- the scheduler 204 is configured to obtain the activity plans 205 and steps 206 from a pre-existing business plan 104, such as those created by the scheduler 103 of FIG. 1. Indeed, a purely acyclic business plan 104 can be divided into a business plan 205 and a step plan 206 from the scheduler 204 according to the invention. Indeed, it is often possible to group a set of activities of a business plan 104 that are connected to each other and to represent them in the form of a flow of steps. This implementation may require, depending on the case, the human intervention to distinguish the activities 201 from the steps 202.
- the activity execution engine 207 is configured to execute at least one activity of the activity plan 205.
- the step execution engine 208 is configured to execute the steps of the step plan 206 sequentially.
- the step execution engine 208 is operably coupled to the activity execution engine 207 so that the steps of the step plan 206 associated with the activity that is being executed by the activity execution engine 205.
- the transition from one step to another is conditioned by at least one predefined passage rule, not based on time. This contrasts with the activities for which the execution of the next activity depends mainly on time.
- the step execution engine 208 is also configured to determine if the pass rule is observed.
- the visual display 209 is operatively coupled to the activity execution engine 207 and the step execution engine 208.
- the visual display 209 of FIG. 4 is configured to display, as a function of time, a first execution state associated with the activity plan 205, in the form of an acyclic oriented graph.
- the first execution state may indicate whether an activity of the activity plan 205 is pending, started, terminated, in error or out of time.
- an activity can be represented as a first graphic object to which graphic attributes associated with the first execution state can be assigned.
- the first graphic object may have as a graphic attribute one or a combination of the following attributes: a color, a pattern or a symbol.
- the visual display device 209 is further configured to display a second execution state associated with the step plane 206, in the form of a step flow diagram.
- a step is represented as a second graphical object that may have the same graphical attributes as the first object.
- the visual display device 209 is further configured to associate the display of the first execution state with that of the second execution state.
- the visual display device 209 may be configured to associate to the first and second graphic objects, the same indicative graphic attribute of the second execution state.
- the corresponding activity will also be shown in green to indicate that the corresponding "business" activity is running.
- the red color is assigned to a step in error, the associated activity will also be shown in red to indicate that there is an error in this business activity.
- the system 200 also comprises an event detection device 210 operatively coupled to the supervised satellite and the execution engine of steps 208.
- the event detection device 210 is configured to detect at least one event associated with the supervised satellite.
- the step execution engine 208 may also be configured to execute at least one step associated with the detected event. For example, this so-called "exceptional" step, because dependent on the occurrence of a particular event, can be executed automatically or at a predetermined date. This may be the case for steps that do not require special attention on the part of the operator and that can be executed automatically.
- the steps execution engine 208 execute automatically one or more steps of thorough diagnosis or problem solving.
- the event detection device 210 may also be functionally coupled to the scheduler 204. The scheduler 204 is then able to schedule the execution of at least an activity associated with the detected event, that is to say according to the nature of the detected event.
- the step execution engine 208 is further configured to determine whether a passing rule is observed based on at least one logic element and / or a detected event.
- a passing rule is observed based on at least one logic element and / or a detected event.
- logic element all the conditional branches for controlling the execution of a step and implying that a choice must be made on the progress of the execution of the steps of a plan of Steps 206. For example, are included:
- the system 200 also comprises a notification device 21 1 operatively coupled to the step execution engine 208 and the visual display device 209.
- the notification device 21 is configured to notify at least one operator of the system 200, information associated with at least one step.
- the notification can be made to a group of people rather than just one.
- the notification device 21 1 can be connected to an electronic mail system and / or an SMS server to which the operator is subscribed.
- the notification device 21 1 can notify the operator of the list of manual steps he is responsible for with the associated information.
- the notification device 21 1 is also configured to propose to the operator, via the visual display device 209, to give a response to the notification.
- the response may be a validation as requested in the example of step "(3) Validation of Maneuver Parameters by a Control Authority" described above as part of a satellite maneuver. north-south type.
- the answer can also be a cancellation of such a step.
- the step execution engine 208 is further configured to determine whether a passing rule is observed based on at least the response of the operator to the notification. Through this mechanism, it is possible to include humans in an automated global system. Thus, for example, in the context of the detection of one of several anomalies, it is possible to include in the system 200 a human activity, for which the operator is presented with all the possible results automatically so that it determines the correct anomaly.
- the operator has a certain time to perform these steps. On the other hand, if he does not execute one (e.g. the operator has not validated his answer), the following steps will not be executed. But since it is not necessary to use the notion of time to represent the flow of steps, the size of the second graphical object associated with the second execution state of the step plan 206 has not you do not have to be dependent on how long it runs. With regard to activities in business plan 205, it is necessary that this be the case to give an indication to the operator of the state of completion of an activity. Thus, the visual display device 209 may be further configured to represent the size of the first graphic object according to a maximum duration of the associated steps.
- the visual display device 209 is also configured to calculate the execution time of an activity taking into consideration the worst case execution. For example, if an activity is associated with three consecutive steps E-1, E-2 and E-3 such that E-1 is expected to last a maximum of 1 hour, E-2 is expected to last a maximum of 2 hours and E -3 is expected to last up to 3 hours.
- a conditional branching makes it possible to execute step E-2 if condition C1 is observed and step E-3 if condition E-3 is observed.
- the worst execution case is therefore 4 hours (i.e. 1 hour of E-1 + 3 hours of E-3).
- the visual display 209 is further configured to represent the first execution state within a first viewing window 220, the second execution state to the interior of a second viewing window 230.
- the activities A-1, A-2, A-3 and A-4 are represented by a first graphic object 222 in the form of a rectangular bar, similar to those used in the Gantt type diagrams.
- the first graphic object 222 associated with the activity A-1 has a dark gray color graphic attribute. In this example, this color tells the operator that the activity is complete.
- the first graphic object 222 associated with the activity A-2 has a light gray color graphic attribute. In this example, this color tells the operator that the activity is running.
- the first graphical objects 222 associated with the activities A-3 and A-4 have a graphical attribute of a 45-degree black hatch pattern. In this example, this pattern tells the operator that the activity is pending execution. In the example of FIG. 6, it is represented the flow of tasks associated with the execution of the activity A-2 and which starts at D and ends at F. In FIG. 6, steps E-1, E-2, E-3.1 and E-3.2 are represented by a second graphic object 231 in the form of a rounded-corner rectangle, similar to those used in the flow diagrams (ie workflow in English).
- the first graphic objects 231 associated with steps E-1 and E-2 have a dark gray color graphic attribute. In this example, this color tells the operator that the step is complete.
- the second graphic object 231 associated with the step E-3.1 has a graphic attribute of color of light gray type. In this example, this color tells the operator that the step is running.
- the first graphic object 231 associated with the step E-3.2 has a graphical attribute of the type of the black hatch pattern at 45 degrees. In this example, this pattern tells the operator that the step is pending execution.
- a third symbol 232 is used to represent a conditional branch where the condition CX is evaluated.
- the loop Iteration 233 makes it possible to represent the following iterative sequence if the condition CX is validated: ⁇ E-2 - E-3.1 ⁇ .
- the first viewing window 220 may be displayed by default and the second viewing window 230 may be displayed automatically in response to the start of a step type or following appearance of a runtime error. For example, by default, the operator only displays the viewing window 220 where activity A-2 is indicated as being running. Then, when the first step E-1 is executed, the second viewing window 230 can be automatically displayed.
- the visual display device 209 further comprises a pointing device and the second viewing window 230 is displayed in response to a signal from the pointing device following the selection of a first graphic object. in the first viewing window 220.
- the operator only displays the viewing window 220 where the activity A-2 is indicated as being running. Then, if the user uses a mouse or a graphics tablet connected to the system 200, when the latter clicks on the first graphical object representing the activity A-2, then the second viewing window 230 is displayed.
- system 200 is also configured to implement a method illustrated by all the steps described in FIG. 7 and which allows the visualization of a business plan over time, the business plan being associated with the supervision of a device, such as a satellite.
- a device such as a satellite.
- S300 we first obtain a business plan and a plan of steps according to the invention.
- S320 the business plan and the associated step plan are executed.
- S330 we display the business plan and the plan of steps, according to the invention.

- the method of displaying a business plan over time according to the invention can be stored on a computer-readable non-transitory storage medium in the form of a computer.
- computer program comprising a set of instructions executable by a computer or a processor.
- the invention has been presented as being able to be implemented in a satellite control center for the supervision of satellites, but it goes without saying that the invention can also be implemented in the supervision center of any system.
