Description

  The present invention relates to a handwritten information input support device.

  A mission computer system is installed in a rotorcraft for missions such as vigilance. The mission computer generates a mission log using sensor information from sensors attached to the aircraft, and records the mission log in a recording device provided in the aircraft. The mission computer calculates the flight specifications of the aircraft based on the detection data from the body sensor and stores it in the mission log. The flight specifications are the position, posture, speed, acceleration, altitude, etc. of the aircraft. The mission log also stores specifications of radar waves radiated from the radar sensor, flight specifications of the target when the target is detected, and details of operations performed by the pilot. The operation content refers to a command or information input to a pointing device or apparatus. The mission computer leaves data such as these flight specifications in the mission log for all events that occurred during the flight.

  A read-only analysis device provided in the mission computer system or the ground facility will later perform post-mortem analysis on all events that occurred during the flight using this mission log. The pilot summarizes the results of the flight operations while referring to this mission log as a report.

  During the mission flight, the pilot notes on the paper on the board attached to the leg with a pencil, etc. as an annotation that he noticed the event. Annotations are annotations and comments that have been noticed by the pilot, such as handwritten characters, symbols and diagrams. When the pilot is notified from the mission computer system that the target has been found, the pilot notes the appearance features of the target as annotations. This annotation is information that the system system cannot directly record as data, and is left as supplementary information on paper by the human system.

  Further, depending on the event that has occurred, the required flight specifications, operation details, or changed flight specifications are different. It is preset in the mission computer that what flight specifications and operation details are recorded for which event. When creating a report, the pilot works to associate the mission logs with annotations while recalling the situation by combining the mission logs launched from the system analysis function or analysis device with the annotations written by him. I do.

  Usually, annotations that are entered as time passes and annotations that are entered when a characteristic event that has been set in advance on a rotary wing aircraft system occurs are the boards attached to the legs by the pilot. The situation of these scenes is held by handwriting on the upper paper and used for later judgments.

  After the system is finished, the pilot organizes, grasps, analyzes, etc. about the passage of time, the events that occurred during the flight, and annotations as post-mortem analysis, and reports the obtained information to the concerned parties. In the situation where the time to create a report is unlimited, there is not much problem in the work from the end of the flight to the report creation.

2. Description of the Related Art Conventionally, a measuring apparatus with a comment input function that includes comment input means for inputting an arbitrary comment as sound or an image is known (see Patent Document 1). The measuring device described in Patent Document 1 has a measuring means for measuring a blood glucose level, displays a blood concentration value as measurement data, and stores date / time information and measurement data in association with each other. This measuring device displays a message asking whether or not it is necessary to input a comment, and the patient can input the comment by voice. Regarding the board used for handwriting input, there is an electronic knee board for flight service that can be installed on the lap by a pilot or on-board operator to electronically record or output various aircraft data. (See Patent Document 2). A portable information terminal device fixing method for fixing a portable information terminal device to an operator's thigh is also known (see Patent Document 3).

  However, under the circumstances where the pilot must carry out work such as organizing these items immediately after returning home and create a report, the time that the pilot can spend on the work is limited. Furthermore, if the post-analysis takes too much time, the information becomes obsolete.

  Conventionally, system records and human records have been separated, and there is no relationship between these system records and human records, so annotations that are only written by the pilot are stored in the system records. Can not be recorded as. The mission log has a data format in which numerical values of specification data, abbreviations indicating operation contents and situations of human devices are listed in a state where each event is collected. Mission logs do not have enough data format for people to read them.

  For this reason, when the pilot prepares a report, it is necessary for a person to match the annotation and the mission log one by one. When the pilot has written a plurality of annotations, the pilot must find out the event corresponding to each annotation from a column of numerical values and abbreviations. It takes time to compare and contrast annotations and mission logs. If the annotation has been written many times or if the number of written papers is large, human error may occur in the process of copying the original annotation to the report.

  In the prior art described above, when an event occurs, an annotation for this event cannot be stored as data in the system system in association with the mission log at the time of event occurrence.

  SUMMARY OF THE INVENTION In view of the above problems, an object of the present invention is to provide a handwritten information input support device capable of storing input information handwritten by a pilot in an aircraft storage device in association with an event log. And

  In order to solve such a problem, according to one aspect of the present invention, an event log is generated for an event collected during a flight using a storage device, sensors, and sensor information from the sensors.

The interface unit outputs the writing information. The handwritten information input support is characterized in that the handwritten information is stored in the storage device by the computer at the same time that the handwritten information is output to the computer. Apparatus is provided.

  According to the present invention, input information handwritten by a pilot can be stored in association with an event log stored in an aircraft storage device.

  Hereinafter, a handwritten information input support apparatus according to an embodiment of the present invention will be described with reference to FIGS. 1 to 3. In the drawings, the same portions are denoted by the same reference numerals, and redundant description is omitted.

  The handwritten information input support device according to the present embodiment is an annotation input support device for a pilot. This annotation input support device has a touch pad, which is a touch-type pen input device, and generates annotation information data by converting annotations written on paper with the operator holding paper on the touch pad. Written information data is sent to a rotary wing aircraft system.

  The pilot performs the flight work with the annotation input support device attached to the leg in the cockpit, and inputs the annotation by hand through paper. The annotation input support device is connected to the mission computer system of the rotary wing aircraft by a signal cable, and the annotation input support device and this mission computer system are brought online in the aircraft.

  The rotary wing aircraft includes a recording device for recording a mission log (event log), sensors attached to the airframe, and a mission computer (computer). Sensors include instruments and devices that detect data for calculating flight parameters such as position, attitude, speed, acceleration, and altitude, indicating the latitude and longitude of the aircraft, and radar waves that emit target waves. And a radar sensor that receives and detects a radar wave reflected by an object. The mission computer is mainly composed of a signal processing device. Using the sensor information from the sensors, the flight specifications of the target, such as its flight specifications, target position, attitude, speed, acceleration, and altitude. In addition, the history of the radar wave specifications and the operations performed by the pilot is recorded in the recording device.

  FIG. 1 is a diagram illustrating a configuration example of an airframe mounting system including an annotation input support device. FIG. 2 is a perspective view showing the appearance of the annotation input support apparatus. The annotation input support device 1 includes a board-like device main body 2 having a rectangular plane shape, a handwriting input unit 4 provided on the device main body 2 and having a touch pad 3, an interface circuit (not shown), and a switch, And a signal cable 5 connected to the interface circuit. The annotation input support device 1 can exchange data with the information recording unit 6 via the signal cable 5.

  The information recording unit 6 is a part of a mission computer and includes a signal processing device 7 and a recording device 8. The information recording unit 6 records the writing information, which is input information written to the annotation input support device 1, in the recording device 8 in association with the mission log calculated when the writing information is handwritten by the operator. I have to.

  The signal processing device 7 performs a signal processing calculation using sensor information necessary for each event and calculates a mission log. A system-side interface circuit (not shown) is connected to the signal processing device 7. The system-side interface circuit notifies the handwriting input unit 4 of control information indicating that the signal processing device 7 is ready to accept annotations input from the handwriting input unit 4. The signal processing device 7 can exchange data with the handwriting input unit 4 via the system side interface circuit and the signal cable 5.

  For the signal processing device 7, a DSP, a microprocessor, a ROM, and a RAM are used. The recording device 8 is a recording medium such as an external recording device or a magnetic disk device provided in the machine body. The recording device 8 is specifically a card-type recording medium or storage medium.

  The apparatus body 2 is attached to the pilot's kneecap from above the clothes by a belt (not shown). A clip 9 is provided at the end of the apparatus main body 2, and the end of the paper 10 is fastened on the upper surface of the handwriting input unit 4 by the clip 9. A rectangular opening is formed in the upper surface of the main body 2 of the apparatus, and the touch pad 3 is visible through the opening.

  The touch pad 3 has a detection surface, and a sheet-like protection member 11 is mounted on the detection surface. When writing is performed on the paper 10 using a writing instrument such as a pencil or a pen, the touch pad 3 detects the pressing force applied to the detection surface via the protection member 11, and detects a contact portion between the writing instrument and the paper 10. Corresponding coordinate values are detected, and coordinate data of coordinates of one point or a plurality of points are output. A memory buffer and an interface circuit (not shown) are provided on the output side of the touch pad 3.

  This interface circuit provides a control signal between the information recording unit 6 and a notification process for outputting a notification that the handwriting input is completed to the information recording unit 6 when a switch provided in the handwriting input unit 4 is pressed. Interface processing for transmitting / receiving and coordinate data from the touch pad 3 are converted into writing information, stored in a memory buffer, and output to the information recording unit 6. The interface circuit is configured to detect pressing of the switch, and notifies the control message signal indicating that the annotation input operation is completed from the pilot side to the information recording unit 6 side. When this switch is pressed, the interface circuit also outputs the writing information of the memory buffer to the information recording unit 6. A CPU, ROM, or RAM is used for this interface circuit.

  When the information recording unit 6 receives an input completion notification from the interface circuit, the information recording unit 6 associates the annotation information with the occurrence event and stores them in the recording device 8. Alternatively, when receiving an input completion notification from the interface circuit, the information recording unit 6 stores the annotation information in the recording device 8 in association with the system time information.

  In the annotation input support device 1, the writing pressure applied by the writing tool and the handwriting of the contact portion of the writing tool with the paper 10 are detected, and the writing information input to the writing surface is detected as writing information, and this writing information is recorded as information. Part 6 is recorded. The paper 10 can be fixed to the writing surface of the handwriting input unit 4. The writing surface is realized by the touch pad 3 or the like, and the portion for fixing the paper 10 is realized by a clip-shaped plate or stick that presses the paper 10 against the writing surface.

  In addition, a post-analysis function is implemented in the system, or an analysis device dedicated to reading a mission log is provided in a facility on the ground. The system or analysis device reads a mission log, which is a history of radar specifications and a history of motion specifications, from this recording device 8, converts this mission log into information data that can be read by humans, and prints the converted data. It is designed to output.

  Next, the operation of the annotation input support apparatus 1 according to this embodiment will be described using the flowchart shown in FIG. FIG. 3 is a flowchart showing a sequence from the annotation input performed by the annotation input support apparatus 1 to the annotation recording to the recording apparatus 6. Instructions and annotations are input to the annotation input support device 1 using a writing instrument.

  The pilot fixes the paper 10 to the handwriting input unit 4 (step S1), activates the annotation input support device 1 using a button or the like (not shown), and the state of the annotation input support device 1 can be detected as input data. To. When an arbitrary time or event occurs in this state, the pilot writes an annotation on the paper 10 by hand. An annotation such as a character string, a symbol, or a handwritten drawing is written on the paper 10, and the same input information as the character string, symbol, or handwritten drawing written on the paper 10 is taken into the annotation input support apparatus 1.

  When the handwriting input unit 4 detects the input of the annotation (step S2), the writing information is transferred to the information recording unit 6. As an example, after the operator finishes writing the annotation, when the annotation input completion switch is pressed to instruct the annotation input device 1 to complete the annotation input, the handwriting input unit 4 detects this pressing and displays an annotation input completion message. Information is notified to the information recording unit 6 (step S3). Upon receipt of this message, the information recording unit 6 reads the written information and holds the input annotation as an image (step S4). Thereby, the annotation is recorded together with the mission log in the recording device 8.

  As an example, when an event of discovery of a target occurs, the information recording unit 6 records the specifications of the radar wave, the position and speed of the target. After being discovered, the position and speed of the target are continuously recorded in the recording device 8 as one of the mission logs. When the image of the target is captured, the pilot inputs to the annotation input support apparatus 1 that he / she has noticed the radar information that changes from moment to moment. This annotation is recorded in association with the mission log as soon as the pilot inputs it.

  When an event that the target has disappeared is obtained, the information recording unit 6 does not record the position and speed of the target in the mission log thereafter. When this shadow disappears, the pilot writes in the annotation input support apparatus 1 that the tracking is stopped. At the same time as writing information is recorded in the system, an annotation is entered to indicate that it has been canceled and the target has been noticed, and this annotation is recorded in association with the mission log.

  When the mission computer detects that a ship that is not allowed to pass through the alert sea area is navigating, the pilot supports the annotation input of the outline of the ship, dirt on the ship, or the number of people on board. A handwritten input is made to the device 1. Simultaneously with this handwritten input, annotations such as the outline, dirt, number of people, etc. are recorded in association with the mission log.

  In this way, when an event occurs, such as when a shadow is captured, when the shadow disappears, or when a target is visually recognized, the pilot supports annotation input for annotations about these events. While writing with a pencil or the like on the paper clipped to the apparatus 1, this annotation is immediately recorded as data in the system.

  Therefore, the annotation input support device 1 records the annotation input by handwriting as the system information simultaneously with the writing operation on the paper. Annotation entered by the human system for the event at the time of occurrence of the event is also stored in the system system, and this storage can be performed simultaneously with the occurrence of the event.

  After the rotorcraft returns to the base, the mission computer system or analysis device performs a post-analysis of the mission log. This system or apparatus converts the mission log into information data in a form that can be seen by humans, and outputs it. By referring to this information data, the pilot creates a report.

  The information obtained by writing on paper on the spot by the human system can be taken into the system system at the same time as writing on the paper. The information input by the system system and the information input by the human system are now available. Associated with the information. This eliminates the need to compare and summarize the mission log and memo when creating a report. It is no longer necessary for humans to coordinate annotations for multiple events with the mission log. Each event and annotations about these events can be stored in association with each other accurately.

  Also, by printing out the mission log, all events that occurred during the flight and annotations about these events can be referenced directly. For example, when a plurality of ships are discovered, annotations such as the characteristics of the ships and the situation at the time of discovery can be acquired immediately after returning for each of these ships.

  In addition, since it is not necessary for the operator to compare and compare the written annotation with the mission log, the time required for the comparison operation can be saved and the work efficiency can be improved. Since there is no human error such as mistakes in annotations, the accuracy of the report contents after the mission can be expected. After returning to the pilot, the pilot can quickly sort out the work and create a report quickly. Obsolete information is also prevented.

  Moreover, since the protective member 11 is provided, even when a pilot performs writing input using a writing tool with a sharp tip, the surface of the writing surface is not damaged. In particular, when the aircraft is shaken and a large inertial force is applied to the aircraft, a large writing pressure may be applied to the surface of the touch pad 3, but since the protective member 11 is provided, the writing surface may be damaged. Is prevented. Instead of the protective member 11, the touch pad 3 whose writing surface itself is protected may be used.

  Further, according to the annotation input support device 1, it is possible to register an annotation in the system even in a narrow space such as a pilot seat. Information written on the paper 10 can be recorded in the system simultaneously with writing by an input device called the annotation input support device 1. Since the annotation input support device 1 has a small shape, it is possible to input the annotation of the pilot without troublesome operation of instruments and the like in the cockpit.

  Further, in order to position the wrist with respect to the apparatus main body 2, the apparatus main body 2 may be formed with a recess for placing the wrist. In this way, the posture of the part ahead of the wrist being written can be maintained correctly.

A transport unit (not shown) that transports the paper on the writing surface, a roll paper take-up unit (not shown) that winds up the transported roll paper, a drive unit (not shown) that drives the roll paper supply unit and the roll paper take-up unit, And a control unit (not shown) that controls driving of the drive unit. This control unit controls driving based on the timing at which the interface unit outputs the writing information to the mission computer. A microprocessor, ROM, and RAM are used for the control unit.

  With such a configuration, when the operator writes down on the paper 10 and then presses the reset switch, the control unit outputs the writing information to the information recording unit 6 and notifies the drive unit of the reset signal. . When the drive unit drives the roll paper supply unit and the roll paper take-up unit, the roll paper is transported by a distance longer than the vertical length of the writing surface of the touch pad 3. As a result, the white paper surface is again set on the writing surface.

  According to the annotation input support device according to this modified example, the trouble of replacing the memo paper becomes unnecessary, and the possibility of losing the opportunity of writing input that can be caused by the work of replacing the paper is eliminated.
