  Hereinafter, embodiments of a data measuring device will be described with reference to the accompanying drawings.

  First, the configuration of the data measuring device 1 will be described with reference to the drawings.

  As shown in FIG. 1, the data measuring device 1 includes an input unit 2, a GPS (Global Positioning System) receiving unit 3, a map data storage unit 4, a storage unit 5, a processing unit 6, and an output unit 7. It is configured to be movable together (for example, to be moved together with the moving body 11 by being mounted on the moving body 11). In the following, the moving body 11 will be described by taking an automobile as an example.

  As an example, the input unit 2 includes an A / D converter (not shown), and is a speed sensor 12 as an example of a mounted device mounted on a mobile body 11 (hereinafter also referred to as “automobile 11”). A speed signal (an example of a signal generated on the moving body, which is an example of a signal generated on the moving body, which is an analog signal indicating a temporal change in the speed of the automobile 11) S1 is input and subjected to A / D conversion (sampling). Speed data D1 is output as data. The input unit 2 is a fuel consumption signal output from a fuel consumption sensor 13 as another example of a mounted device mounted on the automobile 11 (an example of a signal generated on a moving body. (Analog signal indicating the time change) of S2 and A / D conversion (sampling) to output fuel consumption data D2 as other measurement data.

  The GPS receiving unit 3 is based on the time data received from a plurality of GPS satellites (not shown) and the time data Dt output from its own clock (internal clock). The current position of the data measuring device 1 (that is, the current position of the automobile 11) is specified from the calculated distances, and position data Dpo indicating the current position (latitude and longitude) is output. To do. The GPS receiver 3 also outputs the time data Dt as well as the position data Dpo.

  As an example, the map data storage unit 4 is composed of a semiconductor memory such as a RAM or a ROM, or a HDD (Hard Disk Drive), and includes at least a region (a central region or a region including a region where the data measuring device 1 is assumed to be used. Map data Dmap of East Japan etc. is stored in advance. The storage unit 5 includes a RAM, a ROM, and the like, and stores an operation program of the processing unit 6 and the like. The storage unit 5 also functions as a work memory for the processing unit 6.

  The processing unit 6 includes a CPU (not shown), and is selected from a measurement mode that executes detection processing and data measurement processing, and an output mode that executes specific map data creation processing and specific map data output processing. Operate in one of the specified modes. This mode switching is specified by the processing unit 6 based on a switch state (on state or off state) of a mode selection switch (not shown). In this example, the output unit 7 includes a display device such as a liquid crystal display as an example, and is configured as a display unit (hereinafter also referred to as “display unit 7”). The display unit 7 includes a map (a specific map described later) including a place where the measurement data (speed data D1 and fuel consumption data D2) are measured, and an identification symbol M (FIGS. 3, 4, and 5) indicating the place. This measurement data is displayed on the screen.

  Next, the operation of the data measuring device 1 will be described. As an example, as shown in FIG. 2, the automobile 11 equipped with the data measuring device 1 travels on the road A, then turns right on the road A and travels on the road B, and then turns left on the road B. The operation when traveling on the road C will be described as an example.

  In the data measuring device 1, the input unit 2 inputs the speed signal S1 output from the speed sensor 12 and the fuel efficiency signal S2 output from the fuel efficiency sensor 13, and converts them into speed data D1 and fuel efficiency data D2, respectively. Output to unit 6. Further, the GPS receiving unit 3 outputs position data Dpo indicating the current position of the data measuring device 1 (that is, the current position of the automobile 11) and time data Dt to the processing unit 6.

  In this state, the processing unit 6 set to the measurement mode performs the detection process while inputting the speed data D1. In this detection process, the processing unit 6 calculates the absolute value (absolute value of acceleration) of the change amount per unit time of the speed of the automobile 11 indicated by the speed data D1, and the absolute value of this change amount is specified in advance. It is detected whether or not the threshold value is exceeded. Further, when detecting that the absolute value of the calculated change amount is equal to or greater than the threshold value in this detection process (when the measurement start trigger condition is satisfied), the processing unit 6 executes the data measurement process. To do.

  In this data measurement process, the processing unit 6 specifies the time t when the absolute value of the calculated change amount is equal to or greater than the threshold based on the time data Dt output from the GPS receiving unit 3, and this time Speed data D1 and fuel consumption data D2 as measurement data input within a period T having a predetermined length including t are stored in the storage unit 5 in association with the time t. Further, the processing unit 6 uses the position data Dpo input from the GPS receiving unit 3 at this time t as position data indicating the location where the automobile 11 has passed at this time t, similarly to the speed data D1 and the fuel consumption data D2 described above. And stored in the storage unit 5 in association with the time t. In this case, as the time associated with the measurement data and the position data, the measurement start time that is the start of the period T can be used instead of the time t.

  In this example, as an example, the acceleration at the time of deceleration in the road A before the intersection with the road B (the place P1 that has passed at the time t1) is equal to or greater than the threshold, and the road B to the road C from the intersection of the road C and the road C. It is assumed that the acceleration at the time of acceleration immediately after entering (place P2 that has passed at time t2) is equal to or greater than a threshold value.

  In the detection process, the processing unit 6 detects that the absolute value of the change amount per unit time of the speed of the automobile 11 at the place P1 is equal to or greater than the threshold value, and executes the data measurement process. In the data measurement process, the processing unit 6 associates the speed data D1 and the fuel consumption data D2 (before and after the time t1) in the period T1 having a predetermined length including the time t1 in association with the time t1 that has passed the place P1. Speed data D1 and fuel consumption data D2) are stored in the storage unit 5 as measurement data, and position data Dpo indicating the location P1 is stored in the storage unit 5 as position data Dpo1.

  In the detection process, the processing unit 6 detects that the absolute value of the change amount per unit time of the speed of the automobile 11 at the place P2 is equal to or greater than the threshold, performs the data measurement process, Similarly to the time P1, the speed data D1 and the fuel consumption data D2 (speeds before and after the time t2) input within the period T2 having a predetermined length including the time t2 in association with the time t2 passing through the place P2. Data D1 and fuel consumption data D2) are stored in the storage unit 5 as measurement data, and position data Dpo indicating the location P2 is stored in the storage unit 5 as position data Dpo2.

  In this manner, in the data measuring apparatus 1, the processing unit 6 set in the measurement mode performs measurement data (speed data D1 and fuel consumption data D2) at the locations P1 and P2 and position data Dpo1 at the locations P1 and P2. , Dpo2 are stored in the storage unit 5 in association with times t1 and t2 when the automobile 11 passes through the places P1 and P2.

  When the output mode is set subsequent to the measurement mode, the processing unit 6 first executes specific map data creation processing. In this specific map data creation process, for example, the processing unit 6 first measures the measurement data (speed data D1 and fuel consumption data D2) at time t1 stored in the processing unit 6 and the position of the place P1 at this time t1. Data Dpo1 is read from the storage unit 5 together with time t1.

  Next, the processing unit 6 creates specific map data Dsp1 for a specific map including the place P1 indicated by the position data Dpo1 with reference to the map data Dmap stored in advance in the map data storage unit 4 ( (Created based on the position data Dpo1 and the map data Dmap previously stored in the map data storage unit 4) and stored in the storage unit 5.

  Specifically, as an example, the processing unit 6 includes a place P1 indicated by the position data Dpo1 and a predetermined planar shape and area (in this example, FIG. As shown in FIG. 2, the area AR has a rectangular planar shape and a size that can be displayed on the screen 7 a) in accordance with the screen 7 a of the display device as the display unit 7 formed in a rectangle as shown in FIG. 4. Is generated as the specific map data Dsp1 and stored in the storage unit 5.

  Further, when the processing unit 6 creates the specific map data Dsp1 including the place P1 indicated by the position data Dpo1 that has passed at one time t1 in this way, the created specific map data Dsp1 uses the other measurement data as the measurement data. It is determined whether or not the other measured place P is included. As a result of the determination, when another place P is included, the specific map data Dsp1 is stored as the specific map data Dsp including the place P1 and the other place P. On the other hand, when the other place P is not included, it is stored as specific map data Dsp including only the place P1. Thereby, specific map data creation processing is completed.

  In this example, as shown in FIG. 2, the specific map data Dsp1 including the location P1 also includes other locations P (location P2 in this example). Therefore, the processing unit 6 stores the specific map data Dsp1 in the location P1. , P2 is stored in the storage unit 5 as specific map data Dsp.

  Following this specific map data creation processing, the processing unit 6 executes specific map data output processing. In the specific map data output process, the processing unit 6 first reads the specific map data Dsp1 stored in the storage unit 5 and outputs the specific map data Dsp1 to the display unit 7 to be indicated by the specific map data Dsp1. A specific map image (a map image in the area AR including the roads A, B, and C) is displayed on the screen 7a of the display unit 7 as shown in FIG. Further, as shown in the figure, the processing unit 6 has an identification symbol M (in this example, indicating each location P1, P2 at the position on the specific map of each location P1, P2 included in the specific map data Dsp1. As an example, a serial number (a numeric value “1” for the location P1 and a numeric value “2” for the location P2) indicating the location surrounded by the inverted triangle symbol (mark) is displayed in an overlapping manner.

  Next, the processing unit 6 determines whether or not a specific place P among the places P included in the specific map data Dsp1 displayed on the screen 7a is selected by the operator, and the specific place P is selected. When it is determined that the measurement has been performed, the measurement data (speed data D1 and fuel consumption data D2) measured at the selected place P is reduced and displayed at a position close to the place P (near the place P) on the screen 7a.

  Specifically, in this example, when one of the two places P1 and P2 displayed on the screen 7a is selected as a specific place by the operator, the processing unit 6 selects the place P1. 4, as shown in FIG. 4, a position close to the identification symbol M (a symbol in which the numerical value “1” is surrounded by an inverted triangle) indicating the location P 1, that is, the location P 1 on the specific map. The waveform W1 of the speed data D1 and the waveform W2 of the fuel consumption data D2 included in the period T1 including the time t1 are reduced and displayed at a close position (in association with the place P1).

  In this case, since the driver of the automobile 11 performs braking in preparation for the right turn to the road B at the place P1, as shown in FIG. 4, the time t1 passing through the place P1 as the waveform W1 of the speed data D1. The waveform indicating that the speed has been decelerated from high speed to low speed before and after is reduced and the accelerator is returned in accordance with braking (because the fuel is cut in the automobile 11 when the accelerator is returned). ) As a waveform W2 of the fuel consumption data D2, a waveform indicating that the fuel consumption has improved before and after the time t1 is reduced and displayed. For example, the processing unit 6 is displayed when the identification symbol M associated with the displayed measurement data is selected again, or when another identification symbol M is selected as will be described later. The display of the measured data is ended.

  In this example, when the other place P2 of the two places P1 and P2 displayed on the screen 7a is selected as a specific place, the processing unit 6 indicates that the place P2 has been selected. And the display of the measurement data measured at the place P1 is terminated, and as shown in FIG. 5, it is close to an identification symbol M (a symbol in which the numerical value “2” is surrounded by an inverted triangle) indicating the place P2. The waveform W1 of the speed data D1 and the waveform W2 of the fuel consumption data D2 included in the period T1 including the time t2 are reduced and displayed at a position, that is, a position close to the place P2 on the specific map (in association with the place P2) .

  In this case, since the driver of the automobile 11 depresses the accelerator and accelerates the automobile 11 at the place P2 after entering the road C, the place P2 is set as a waveform W1 of the speed data D1 as shown in FIG. The waveform indicating that the speed has been accelerated from low to high before and after the passing time t2 is displayed in a reduced size, and the fuel consumption has decreased before and after the time t2 as the waveform W2 of the fuel consumption data D2 due to the depression of the accelerator. The waveform indicating is reduced and displayed.

  In addition, as a structure which selects each place P1, P2 by an operator, the structure which comprises the screen 7a with a touch panel and touches each identification symbol M which shows the places P1, P2 with a finger | toe can also be employ | adopted. In addition, it is possible to adopt a configuration in which each identification symbol M indicating the locations P1 and P2 is designated and selected using a pointing device such as a mouse, or a numerical value indicating each location is input from a keyboard or the like. It is also possible to adopt a configuration that does this.

  Thus, in this data measuring device 1, each of the waveforms W1 and W2 of the speed data D1 and the fuel consumption data D2 (both measured data) within the period T1 including the time t1 that has passed the place P1 is an identification symbol indicating the place P1. It is associated with M (position information) and displayed on the screen 7a of the display unit 7 together with a specific map (map information) including the place P1. Further, the waveforms W1 and W2 of the speed data D1 and the fuel consumption data D2 (both measured data) in the period T2 including the time t2 when passing the place P2 are associated with the identification symbol M (position information) indicating the place P2. These are displayed on the screen 7a of the display unit 7 together with a specific map (map information) including the place P2.

  Therefore, according to the data measuring apparatus 1, the operator can move the car at any position in the specific map due to the presence of the identification symbol M indicating the places P1 and P2 displayed on the specific map displayed on the screen 7a. The absolute value of the change amount per unit time of the 11 speeds is equal to or greater than the threshold value, so that it is possible to reliably grasp whether the speed data D1 and the fuel consumption data D2 (measurement data) have been measured, and the locations P1, P2 Based on the speed data D1 and the fuel consumption data D2 associated with this identification symbol M displayed together with the identification symbol M indicating, the contents of the measurement data (changes in speed and fuel consumption) at each of the locations P1 and P2 are assured. Can grasp.

  Further, in the data measuring apparatus 1, the processing unit 6 displays the specific map on the screen 7a of the display unit 7, and the place P1 where the measurement data (speed data D1 and fuel consumption data D2) included in the specific map is measured. , P2 indicates the identification symbol M associated with the measurement data, and when the identification symbol M is selected, the measurement data associated with the selected identification symbol M is reduced and displayed on the display unit 7.

  Therefore, according to this data measuring device 1, even when there are many places P where measured data (speed data D1 and fuel consumption data D2) are measured in the specific map displayed on the screen 7a. The location where the measurement data is measured can be reliably grasped, and only the measurement data (speed data D1 and fuel consumption data D2) measured at the location P to be confirmed are selected on the screen 7a (selected on the screen 7a). Therefore, the contents of the measurement data can be reliably grasped.

  Moreover, according to this data measuring device 1, since the process part 6 employ | adopts the structure which displays the measurement data reduced, the area | region on the specific map covered with the displayed measurement data can be decreased. (In other words, more areas can be displayed.) Thus, even in a state where the measurement data is displayed, the position on the specific map of the place P where the measurement data is measured, and this place A map around P can be grasped sufficiently.

  Moreover, in this data measuring device 1, the structure which the process part 6 reduces and displays measurement data is employ | adopted. For this reason, even if the measurement data measured at each place P is simultaneously displayed on the screen 7a when the number of places P where the measurement data (speed data D1 and fuel consumption data D2) in the specific map are measured is small, It is possible to reliably identify which measurement data is measured at which place P. Therefore, in such a case, an operation of selecting any one of the identification symbols M displayed at each location P included in the specific map is omitted, and the identification symbols M are placed in the vicinity of all the identification symbols M. It is also possible to adopt a configuration for displaying the associated measurement data.

  In the above example, the identification symbol M associated with the measurement data is added to the locations P1 and P2 where the measurement data (speed data D1 and fuel consumption data D2) included in the specific map displayed on the screen 7a is measured. When the identification symbol M is selected, the measurement data associated with the selected identification symbol M is displayed on the display unit 7 in a reduced manner. However, it is associated with the selected identification symbol M. It is also possible to employ a configuration in which the measured data is displayed over the entire area or almost the entire area of the display unit 7. According to this configuration, the content of the measurement data can be confirmed in more detail. Further, it is also possible to adopt a configuration in which measurement data is displayed in the entire area or almost the entire area of the display unit 7 by instructing the entire area display in the operation unit in the reduced display state.

  In the data measurement apparatus 1 described above, the automobile is described as an example of the moving body 11 that moves together. However, in addition to the automobile, the moving body is mounted (attached) to a moving body such as a bicycle or a person. The signal generated on the moving body may be measured while moving together. As an example, when it is configured to move with a person as a moving body, a configuration is adopted in which the data measurement device 1 is attached to a person together with a blood pressure sensor and a pulse sensor, and the blood pressure data and pulse data of the person are measured as measurement data. You can also.

  Also in this configuration, the data measuring device 1 is the same as when mounted in the automobile, for example, the processing unit 6 indicates that the blood pressure value of the person indicated by the blood pressure data at the time of walking is equal to or greater than a predetermined threshold value. Is detected, the processing unit 6 executes a data measurement process, and the measurement data input within a period including the time when the threshold value is exceeded is stored in the storage unit 5 in association with this time. Let In addition, the processing unit 6 associates the position data Dpo input from the GPS receiving unit 3 at this time as position data indicating the place where the person has passed at this time in the same manner as the above measurement data. Store in the storage unit 5.

  Therefore, according to this data measuring apparatus 1, the operator can predetermine the blood pressure value at any location P due to the presence of the identification symbol M indicating the location P displayed on the specific map displayed on the screen 7a. The measured value (blood pressure data and pulse data) can be surely grasped when the threshold value is exceeded, and is associated with the identification symbol M displayed together with the identification symbol M indicating the place P. Based on the measurement data (blood pressure data and pulse data), it is possible to reliably grasp the contents of the measurement data at each location P (the changes in blood pressure and pulse).

  In the above example, the data measuring device 1 measures a signal related to the moving body itself on which the data measuring device 1 is mounted (attached) as a signal generated on the moving body. As the signal generated on the moving body, the data measuring apparatus 1 is mounted on the automobile or the bicycle, and the data measuring apparatus 1 generates a signal related to the person (person is also a moving body) riding on the moving body. A configuration for measuring can also be adopted.

  In the above-described example, the output unit 7 is configured as a display unit including a display device. However, the output unit 7 is configured as an interface unit for communicating with an external device, and the created specific map data Dsp is stored in the places P1, P1. A configuration in which measurement data associated with the identification symbol M (positional information) indicating P2 is output to an external device can also be employed. In addition, it is configured as an interface unit to which an external memory such as a removable medium is connected, and the created specific map data Dsp is stored in the external memory together with measurement data associated with identification symbols M (position information) indicating the locations P1 and P2. It is also possible to adopt a configuration for storing in the memory.

  In this configuration, an external device (a device having a display unit) is associated with the specific map data Dsp and the identification symbol M (position information) indicating the locations P1 and P2 via the interface unit or the external memory. By acquiring the measurement data and executing the same process as the specific map data creation process and the specific map data output process described above, the measurement data is specified on the screen of the display unit in a state associated with the position data. Can be displayed with a map. Therefore, in the above example, the operator can detect the speed of the car at any location in the specific map due to the presence of the identification symbol indicating the location displayed on the specific map displayed on the display screen of the external device. The absolute value of the amount of change per unit time is greater than or equal to the threshold value, so that it is possible to reliably grasp whether the measurement data has been measured, and it is associated with this identification symbol displayed together with the identification symbol indicating the location Based on the measurement data (speed data and fuel consumption data), the contents of the measurement data (changes in speed and fuel consumption) at each location can be reliably grasped.
