=== Basic configuration of apparatus ===
FIG. 1 is an external view of a portable process schedule management apparatus according to an embodiment of the present invention. The portable process schedule management device 1 is a wristwatch type equipped with a band 2 to be worn on an arm, and the basic structure and configuration is a liquid crystal display (LCD) 4 on the front surface of a case 3 as a dial. It is the same as the digital wristwatch provided. On the side surface of the case 3, a plurality of buttons 5 for operating the portable process schedule management device (hereinafter, list computer) 1 are arranged.

  FIG. 2 shows a display pattern of the LCD 4. Icon pattern 41 for dedicated display of specific characters and figures, 7-segment pattern 42 for displaying numbers, and two large and small dot matrix patterns (43a, 43b) for bitmap display of text and figures Is arranged.

  FIG. 3 shows a functional block configuration of the list computer 1. The hardware configuration of the wrist computer is the same as that of a so-called “outdoor watch” wristwatch equipped with various sensors (29 to 32) and displaying information such as temperature, atmospheric pressure, altitude, and direction. A computer main body including the MPU 20, the RAM 21, and the ROM 22 is used as a controller, and various programs executed by the MPU 20 and font data are stored in the ROM 22. In addition, a flash memory 34 is incorporated as an external storage.

  The oscillation circuit 23 and the frequency dividing circuit 24 are circuits that generate clocks having various frequencies, and generate a reference clock for operating the MPU 20 and a clock related to a time measuring function such as a time display and a stopwatch. The display control unit 25 displays various types of information on the LCD 4 in accordance with instructions from the MPU 20, and the operation control unit 26 inputs operation signals from the operation buttons 5 to the MPU 20. The sound control unit 28 drives the speaker 27 in accordance with an instruction from the MPU 20 and outputs sound such as an alarm sound.

  Furthermore, in addition to the atmospheric pressure sensor 29, the temperature sensor 30, and the azimuth sensor 31, in addition to the atmospheric pressure sensor 29, the temperature sensor 30, and the direction sensor 31, vibrations associated with walking are provided in order to realize a function (outdoor function) for providing users with various information intended for outdoor use. A sensor 32 for detection is provided. In this embodiment, the acceleration sensor 32 is employed. And the signal which each sensor (29-32) outputs is digital data (atmospheric pressure data, temperature data, azimuth | direction data) in the A / D conversion circuit (33a-33d) corresponding to each sensor (29-32). , Vibration data) and input to the MPU 20.

  The MPU 20 executes a predetermined program stored in the ROM 22 in response to an operation signal from the operation control unit 26, writes the execution result of the program into the RAM 21, and reads out the written data from the RAM 21. To do. The MPU 20 also stores various data from the A / D conversion circuits (33a to 33d) connected to the sensors (29 to 32) in the RAM 21 so that they can be read out while being updated at every sampling opportunity.

  Further, necessary information is generated at any time based on the stored various data and stored in the RAM 21. For example, the altitude is calculated based on the atmospheric pressure data from the atmospheric pressure sensor 29 from the relationship between the atmospheric pressure and the altitude stored in advance, and the calculation result is stored.

  The list computer 1 also has a pedometer function, stores the step length input by the user in the flash memory 34, and the MPU 20 analyzes vibration data from the acceleration sensor 32 to extract vibrations associated with walking. The number of steps is counted based on the vibration, or the walking distance is calculated by multiplying the number of steps by the step length. Then, the walking distance starting from the time when the user performs a predetermined operation input is calculated, and the calculation result is updated and stored in the RAM 21.

  Furthermore, the list computer 1 has a function of communicating with an external information processing apparatus such as a personal computer (PC), and includes a communication interface (IF) 35 as a configuration therefor. The MPU 20 transfers various data to the information processing apparatus and receives various data from the information processing apparatus via the communication IF 35.

  The communication IF 35 and the external information processing apparatus may be connected directly or may be connected via an intermediate device called a cradle. In this embodiment, the communication IF 35 communicates with the cradle by a radio signal using radio waves or infrared rays.

  4A and 4B show a list computer 1 mounted on the cradle 50 and a schematic configuration of an internal circuit of the cradle 50. FIG. The cradle 50 includes a wireless communication IF 51 for communicating with the communication IF 35 of the list computer 1 by a wireless signal, and a general-purpose communication IF 52 for communicating with the information processing apparatus using a protocol according to a general-purpose communication standard. A controller 53 having a RAM and a ROM interprets signals having different protocols transmitted and received via both communication IFs (41, 42) and performs mutual conversion. Note that the cradle 50 and the information processing apparatus are connected to each other via, for example, a cable 55 having connectors 54 conforming to the USB standard at both ends. With such a configuration, the MPU 20 of the list computer 1 communicates with an external information processing apparatus indirectly via the communication IF 35. Then, the MPU 20 stores the data transferred from the external information processing apparatus via the communication IF 35 in the flash memory 34, or transfers the data in the flash memory 34 to the external information communication apparatus.

  The list computer 1 having the above configuration displays information related to the outdoor function and the clock function, received data, execution results of information processing, and the like on the LCD 4 and outputs an alarm sound from the speaker 27 under the control of the MPU 20. Or

  Further, the list computer 1 stores information on the climbing and trekking schedule (reference schedule information) created in advance by the user, and updates the schedule from time to time while comparing it with the actual process. It has a schedule management function that presents the contents of the latest schedule to the user. In addition, according to the schedule management function of the present embodiment, there is also provided a function for assisting the user in safely climbing or trekking by reliably checking the difference between the reference schedule and the actual process.

=== Reference schedule information ===
The flash memory 34 stores reference schedule information as information for realizing the schedule management function. FIG. 5 shows the data structure of the reference schedule information 60. In this embodiment, a plurality of waypoints Pk (k = 1, 2, 3,..., N−1) are set in the middle of the departure point P0 and the destination point Pn. In this figure, a mountain climbing schedule is shown. As information about each point 61, a name 62 and an altitude 63 are included, and a distance 64 between each point and a scheduled walking time 65 are also described. Has been. For example, P0 and P1 have a distance of 2400 m (distance between points), and the scheduled walking time is 55 minutes.

  Of course, the data structure and description contents of the reference schedule information 60 can be changed as appropriate. For example, the point-to-point distance 64 may be described as a distance from the departure point P0, or a break time at each point 61 may be described in addition to the scheduled walking time 65. Instead of the scheduled walking time 65 between the points, it is possible to describe the cumulative walking scheduled time from the departure point P0, or to describe the scheduled departure time and the estimated arrival time of each point 61. At least the distance 64 between each point can be specified, and at the stage where the scheduled departure time of the departure point P0 or the actual departure time is specified, the estimated arrival time of each subsequent point 61 can be specified. That's fine.

=== Input of reference schedule information ===
The reference schedule information shown in FIG. 5 may be stored in the list computer 1 from the beginning. In addition, although it takes time, it is possible to input text and numerical values using the operation buttons 5. However, in this embodiment, the reference schedule information 60 is input from an external information processing apparatus using a communication function provided as a standard in the list computer 1.

  For example, with a PC as an information processing device, software for editing the reference schedule information 60 is installed in the PC. The user edits the reference schedule information 60 using the PC and creates a file in a predetermined format. To do. Then, the file is transferred to the flash memory 34 and stored. The MPU 20 recognizes a file in a predetermined format as the reference schedule information 60.

  Alternatively, the reference schedule information 60 may be prepared on a Web server so that it can be downloaded. In this case, the PC need only have a browser installed, and it is not necessary to install editing software for the reference schedule information 60.

=== Setting the standard schedule ===
In order to make the contents of the reference schedule information 60 correspond to the time in the actual process, it is first necessary to define the scheduled arrival time of each point 61. In this embodiment, since the estimated arrival time is not described in the reference schedule information 60, the estimated arrival time of each point is added to the reference schedule information 60 based on the actual departure time and the estimated walking time 65 between the points. Is to be added.

  In order to add the estimated arrival time to the initial reference schedule information 60, the user performs a predetermined operation input at the departure point and performs an operation for instructing that the current point is the departure point P0. FIG. 6 shows the transition of the display state of the LCD 4 in accordance with the input of the departure point instruction. In the time display state (A) which is a basic display state, a predetermined operation button 5 for calling a screen corresponding to various functions is pressed to display a screen related to the schedule management function (schedule management screen). When other buttons 5 are pressed in this display state, various information related to the schedule (current location, next location, estimated arrival time of the next location, time until arrival, distance, altitude, etc.) are sequentially recalled. Can be displayed. Various information related to the schedule management function can also be input by operating the predetermined button 5.

  When displaying the schedule management screen, the MPU 20 displays information about the departure point P0, and each time a predetermined operation input is received, the point is sequentially advanced to P1, P2,..., And information about each point is displayed. Here, when the information of the departure point P0 is displayed, “P0” 45 indicating that the departure point is small is displayed in a state where the current time 44 is displayed in the time display 7-segment pattern (42a, 42b). The area is displayed in the dot matrix pattern area (sub-dot pattern area) 43b, and the name 46 is displayed in the dot matrix pattern area (main dot pattern area) 43a. It should be noted that the departure time 47 is not input until the current location instruction is input.

  When the user depresses the predetermined button 5 at the time of departure and indicates that the current point is the departure point P0, the MPU 20 acquires the time at the input time by storing it in the RAM 32, etc. It is displayed on the name 46 of the main dot pattern area 43a (B).

  Further, according to the scheduled walking time 65 between the points included in the reference schedule information 60, the estimated arrival time at each point is calculated, and the reference schedule information is updated by associating the estimated arrival time with each point. The basic schedule information is stored in the flash memory 34. FIG. 7 shows the data structure of the reference schedule information 60b with the estimated arrival time 66 appended thereto.

=== Generation of the latest schedule information ===
In the same manner as when the user is at the departure point P0, the MPU 20 performs an instruction input (current point input) indicating that the user has arrived at the point 61 at each point 61. Recognize which point is listed between and which point. That is, when the user displays a specific point on the schedule management screen and indicates that the point is the current point, the MPU 20 sets a flag indicating that the point has arrived. If two consecutive points have arrived and have not arrived, it can be specified that the current position is between the two points.

  Each time the MPU 20 receives an input of the current location at each location, the MPU 20 generates the latest schedule information in which the content of the reference schedule information 60b is changed according to the actual process. FIGS. 8A to 8C show the transition of the screen displayed on the LCD 4 in the process of generating the latest schedule. When the user starts walking from the departure point P0 and comes to the first waypoint P1, the user operates the list computer 1 to call the schedule management screen. The calling screen displays the departure point “P0” display 45, its name 46, and the departure time 47 previously input at the departure point P0 with the current time 44 displayed (A). . Here, a predetermined operation input is performed to display information of the first waypoint P1 (B). On this display screen, “P1” 45, which is the first waypoint, and its name 46 are displayed, and the arrival schedule for P1 described in the reference schedule information 60b with the estimated arrival time is added. Time 47a is displayed. In this state, the user can confirm the difference from the original scheduled arrival time from the current time 44 displayed on the same screen. When the current point input indicating that it is the transit point P1 is performed by pressing the predetermined button 5, the MPU 20 acquires this input time and displays the actual arrival time 47b instead of the estimated arrival time (C). Based on the time 47b and the scheduled walking time 65 between the points included in the reference schedule information 60b, the estimated arrival time of each point 61 after the next waypoint P2 is calculated, and the estimated arrival time 66 The latest schedule information that associates with each point 61 is generated.

  FIG. 9 shows an outline of the latest schedule information 70 generated. In this example, the difference ΔTw73 between the scheduled walking time 65 between the points included in the reference schedule information 60b and the time actually taken and the time difference ΔTp74 between the estimated arrival time of the waypoint P1 are calculated, and these time differences ( ΔTw73, ΔTp74) are also included in the latest schedule information 70. For the point P1, a “done” flag indicating that the current point has been input is set.

  The contents of the latest schedule information can be appropriately displayed on the schedule management screen according to a predetermined operation input by the user. FIG. 10 shows a display example of each time difference (ΔTw, ΔTp). Here, since the first waypoint P1 is instructed, the same time difference is displayed in both the state (A) displaying ΔTw (48a) and the state (B) displaying ΔTp (48b).

  The user performs the same operation as the operation at the route point P1 at the next route point P2, and displays the estimated arrival time of P2 together with the name. FIGS. 11A and 11B show transition of the display state of the LCD 4 when the second waypoint P2 is input at the current point. In the state (A) in which the information about the waypoint P2 is first displayed, the estimated arrival time 47a is described in the latest schedule information 70 generated at the time when the current point of the previous waypoint P1 is input. The estimated arrival time 47a corresponding to the route point P2, and the user compares the estimated arrival time 47a displayed on the same screen with the current time 44, so that the estimated walking time between the points and the actual walking time are The difference can be confirmed. Then, when a current point input operation is performed to indicate that the current point is P2, the arrival time at this point is calculated as the arrival time of the actual via point P2, and the latest schedule information is updated. . Further, the designated time 47b is displayed together with the name 46 of P2 (B).

  FIG. 12 shows an outline of the latest schedule information updated at the waypoint P2. A difference ΔTw between the estimated walking time corresponding to the waypoint P2 and the actual walking time and a difference ΔTp between the estimated arrival time in the reference schedule information are appended. Then, when the user performs a predetermined operation, the MPU 20 acquires these time differences (ΔTw, ΔTp) and, as shown in FIG. 13, a specific difference ΔTw with the scheduled walking time between P1 and P2. (A) or the difference ΔTp from the estimated arrival time in the reference schedule information (B).

=== Modification of Latest Schedule Information ===
If the standard schedule information includes the estimated arrival time from the beginning, the original standard schedule information and the first latest schedule information that has changed the estimated arrival time of each point based on the actual departure time will not be overwritten, Thereafter, at each waypoint, either the reference schedule information or the first latest schedule information may be selected and displayed as a comparison target with the actual arrival time. Thereby, the user can confirm the difference between the schedule and the current state based on either the time or the scheduled walking time between points.

  14A and 14B illustrate the initial reference schedule information 60c and the first latest schedule information 70b, respectively. For example, when the departure time of the return bus is determined at the destination point, it is assumed that the reference schedule information 60c is compared with the current state. When there are accommodations at both the destination point and the waypoint, and when the accommodation point is determined by predicting the arrival point by sunset, the estimated arrival time 71b in the first latest schedule information 70b and the current state are obtained. Comparison is assumed.

=== Via-point arrival forecast function ===
The basic information processing and operation procedure of the process schedule management function has been described above. However, this basic information processing is based on the premise that the user performs an operation of reliably instructing the current location at each waypoint. That is, if the user does not reliably perform an operation for indicating the current location at each location, the difference between the reference schedule and the current status cannot be presented correctly. In view of this, the list computer 1 according to the present embodiment also includes a via point arrival prediction function for notifying each point when the point is approached so that the current point input operation is surely performed at each point. In the present embodiment, the waypoint arrival forecast function is realized by the clock function and the outdoor function provided in the list computer 1.

  FIG. 15 shows the flow of information processing related to the point arrival forecast function. The time difference t, the walking distance difference d, and the altitude difference h, which are numerical values defining a predetermined range for determining the timing for outputting the forecast, are stored in the ROM 22 or the flash memory 34 in advance or by user input. ing. It is assumed that the user gives an instruction that there is a current point at a certain point Pk (k = s, 1, 2,... E). When this instruction is input, the MPU 20 acquires the time at the input time by storing it in the RAM 32 (s2 → s3). Further, the scheduled walking time 65 between the points included in the reference schedule information 60b is acquired, and the latest schedule information 70 is generated (s4, s5).

  Next, for the next point Pk + 1, the estimated arrival time 66 of the next point Pk + 1 described in the latest schedule information 70, the inter-point distance D (k + 1) 64 to the next point Pk + 1, and the reference schedule information 60b The included elevation H (k + 1) 63 is acquired (s6 to s8). Then, by the pedometer function, the measurement of the walking distance D, the monitoring of the time T, and the monitoring of the altitude H are started from the point Pk (s9 to s11).

  The MPU 20 measures the inter-point distance D (k + 1) 64 to the next point Pk + 1 within a predetermined time difference t within which the difference between the current time T and the estimated arrival time T (k + 1) 66 of the next point Pk + 1 acquired previously is defined. If the difference in walking distance D is within a predetermined distance difference d and the difference between the altitude H (k + 1) 63 of the next point Pk + 1 and the current altitude H is within a predetermined altitude difference h, an alarm sound is output from the speaker. 27, a voice is output from the terminal 27, or predetermined information is displayed and output on the LCD 4, etc., so as to output a forecast (s12 → s15, s12 → s13 → s15) that the vehicle will soon arrive at the next point. , S12 → s13 → s14 → s15). As for the difference between the altitude of the next point and the current altitude, an absolute value is adopted because there is climbing and descending.

  The user is conscious of inputting the current location at the next location because a forecast to that effect is output when the location is near the next transit location in this way. Therefore, it is possible to reliably perform the current point input without forgetting. FIG. 16 shows the display output state of the point arrival forecast. (A)-(C) respectively correspond to the state of the forecast display based on the time difference t, the forecast display based on the walking distance difference d, and the forecast display based on the altitude difference h. A time 49a, a distance 49b, and an altitude 49c to the next point 45 are displayed together with the name 46 of the next point.

<About altitude>
Since the altitude is calculated at an altitude of 0 m when the pressure is 1 atm, an error occurs in the calculated altitude if the atmospheric pressure changes due to weather or the like even at the same altitude. Therefore, instead of outputting the point arrival forecast based on the absolute altitude, the point arrival forecast may be output based on the altitude difference from the current point. FIG. 17 shows the information processing part of the point arrival forecast based on the altitude difference. Similar to the flow of information processing shown in FIG. 13, when an instruction input of the current location is input in a state (s1) where a predetermined numerical range h for the altitude difference is set, the MPU The altitude based on the data is set as the reference altitude (s2 → s21). Further, an altitude difference ΔH between the current point Pk and the next point Pk + 1 is calculated based on the altitude information included in the reference schedule information (s22, s23). Then, the difference Δh between the altitude calculated at each sampling opportunity and the reference altitude is monitored, and the difference (ΔH−Δh) between the altitude difference Δh and the altitude difference ΔH based on the reference schedule information is within a predetermined range Δh. The point arrival forecast is output. As a result, the forecast can be accurately output as long as the atmospheric pressure does not change drastically in a short time.

<About altitude correction>
As described above, since the altitude is calculated based on the atmospheric pressure, it is inevitable that a certain amount of error occurs. However, the list computer 1 of the present embodiment has a process schedule management function, and stores reference schedule information (60, 60b) including accurate elevation information 63 of each point in order to realize the function. is doing. Then, by using this accurate altitude information 63, it is possible to correct the altitude based on the atmospheric pressure.

  Specifically, the user inputs the current location at each location in order to use the process schedule management function. Therefore, when there is a current point input at a certain point, the MPU 20 acquires the altitude 63 of this point 61 in the travel schedule information 60b, and calculates the altitude value calculated based on the atmospheric pressure data from the atmospheric pressure sensor 29. The altitude is corrected in accordance with the value of the altitude 63. As a result, the altitude is corrected at each point, the correct altitude can be confirmed during the journey, and when a point arrival forecast is output based on the altitude, a forecast can be output at a more accurate timing. it can.

=== Other Embodiments ===
<About point arrival forecast output>
In the point arrival forecast function in the above embodiment, in addition to the time, when either the walking distance or the altitude falls within a predetermined range with respect to the corresponding information (distance between points, altitude) in the reference schedule information 60b, the forecast is issued. Since it is output, even if the walking speed is too fast, a forecast is surely output before reaching the waypoint, and it is possible to prevent the user from forgetting to input the current point at the waypoint. Of course, if the forecast is output at an earlier time with some margin with respect to the estimated arrival time, only the forecast output based on the time may be used. Therefore, even if the forecast is not output based on all the conditions of time, walking distance, and altitude, there is no big problem even if the forecast is output based on any one of the conditions.

  However, there is a possibility that if the forecast is issued too early, you will forget the fact of the forecast before you arrive at the current location. Moreover, it can be said that it is preferable to output the forecast by combining any of the time, the walking distance, and the altitude for the purpose of making the user confirm the difference from the latest schedule.

<Setting of point arrival forecast output timing>
As mentioned above, there is a problem that the forecast is issued too early. And if the point arrival forecast is output based on the difference in altitude and the difference between the distance between the points and the walking distance, the forecast is output at an appropriate timing unless the estimated walking time between the current point and the next point is taken into account. Sometimes it becomes impossible. Therefore, for the difference in altitude from the altitude or the difference between the distance between points and the walking distance, the predetermined range value (h, d) for defining the output timing of the forecast is not set uniformly, and the forecast is output. Even when determining based on the difference in altitude or the difference between the distance between points and the walking distance, it may be set so that a forecast is output a predetermined time before the scheduled arrival time at the next point. That is, a predetermined range of values (h, d) for determining the timing for outputting the forecast may be set individually for each of the two points before and after.

  For example, based on the reference schedule information 60b shown in FIG. 7, at the stage of departure from the departure point 1P0, the estimated arrival time of the next waypoint P1 is 6:04, and a forecast is output five minutes before this In this case, the forecast output time t is set to 5 minutes. First, based on the reference schedule information 60b, the elevation difference ΔH = 1540-1240 = 300 m between the departure point “P0” and the next point “P1” A distance ΔD = 2400 m and a scheduled walking time T = 55 minutes are acquired.

  Next, the altitude difference ΔH and the point-to-point distance ΔD are divided by the walking time T, and the value is multiplied by the previous forecast output time t = 5 minutes. Thereby, the altitude difference h = t × ΔH / T that is a numerical range for outputting a forecast a predetermined time t before the estimated arrival time at P1, and the difference between the distance between points and the walking distance d = t × ΔD / T is required. The MPU 20 monitors the altitude and the walking distance, and when the altitude difference from the altitude of the waypoint P1 becomes d, and the difference between the distance between the departure point P0 and the waypoint P1 and the walking distance becomes d. A forecast is output when Similarly, every time the current location input is received and the latest schedule information is generated, h and d are set so that the time is 5 minutes before the scheduled arrival time at the next location. In this way, by setting the movement distance per predetermined time t, that is, the altitude change and the walking distance individually between the points, it is possible to issue a forecast at an appropriate timing.
