Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial applications]

The present invention relates to a pedometer, and more particularly to a pedometer provided with a walking determination unit that determines whether or not a signal is considered to be a walking state when a signal regarded as walking is input by determining whether or not the signal continuously enters. It is.

[Prior art]

The counting of the number of steps by a pedometer is generally performed by detecting the vertical acceleration of a human body with a sensor such as a pendulum or an acceleration sensor. However, since many of the vertical accelerations are generated by actions other than walking, the count value becomes larger than the actual number of steps. Therefore, in order to prevent a motion other than walking from being counted as a walking motion, whether the vehicle is in a walking state depending on whether a signal regarded as walking at the start of counting continuously enters or is due to another motion. Provide a determination unit for determining, and only when a signal continuously enters, it considers that it is in a walking state and performs counting, and when a signal does not continuously enter, as an operation other than walking,
A signal which does not count this signal is provided.

[Problems to be solved by the invention]

However, in the above pedometer, the counting display of the number of steps is not advanced until it is determined that the walking operation is performed, and after the determination, the counting is started in a state in which the number of steps being determined is added at once. Therefore, from the viewpoint of the user, the number of steps is not counted in the initial stage of walking, where the operation is most frequently checked, so that the operation is often recognized as a malfunction or failure. In order to prevent this, the count display was advanced even during the above-mentioned determination, and in some cases, the count display was returned to the original state when it was not determined that the user was walking. Many people think that they are malfunctioning because they are subtracted, and this is also a frequent claim. The present invention has been made in view of such a point, and an object of the present invention is to be able to accurately count the number of steps and also to easily recognize an operation state and to misunderstand a user. There is no pedometer to provide.

[Means for Solving the Problems]

Thus, the present invention provides a walking determination unit that determines whether or not a walking state is determined by whether a signal regarded as walking continuously enters a predetermined number of times, and counts the number of signals regarded as walking during this determination operation. A pre-count display section to be displayed;
And a main count display unit for displaying the number of signals regarded as walking when it is determined that the user is in a walking state as a determined number of steps. [Operation] According to the present invention, the number of steps is displayed on the pre-count display section during the determination of whether or not the user is walking. During this time, even if the display of the main count display section does not advance, the user may malfunction. It is not misunderstood. [Embodiment] Hereinafter, the present invention will be described in detail with reference to the illustrated embodiment. This pedometer is used by being mounted on a user's waist or the like, and detects a vertical acceleration caused by walking. Sensor 11 that amplifies the output of sensor 11
2. It comprises a filter 13 for removing noise, a step counting circuit 14, and a display unit 15. The step count circuit 14 includes an A / D converter 21, an operation unit 23, a step pulse determination unit 22, and a continuous / stop determination unit 24.
The continuity / stop determination unit 24 includes a pre-count unit 25 and a main count unit 26. 31 in the figure
Is a mode changeover switch for changing the display mode to, for example, a walking distance or a calorie consumption in addition to the number of steps, 32 is a reset switch, and 33 is a constant setting switch for inputting a stride length or the like. As shown in FIG. 3, the display unit 15 is constituted by a liquid crystal display. In addition to the main count display unit 16 for displaying the number of steps by numbers, a plurality of bar-type displays are arranged in a line. Pre-count display section lined up
17 are provided. The description of the display of the walking distance and the calorie consumption is omitted. In operation, when the signal output from the sensor 11 is considered to be generated by walking in the step count pulse determination unit 22, this signal enters the continuous / stop determination unit 24,
After the pre-count, the process proceeds to the main count. That is, while setting the pre-count value to 0,
For a short time after a certain signal is input, a dead zone time Tmask for disabling the reception of the next signal is set to the initial setting value Tmask1, and then a walking signal is awaited. The time t from rise to fall is the maximum value Tmax and the minimum value of the walking pulse judgment width
It is determined whether it is within Tmin, and if it is determined that the user is walking, one step is displayed on the pre-count display unit 17 (FIG. 3B). And the dead zone time Tmask for a while
After passing through, it is determined whether or not the pre-count value has become larger than the predetermined value N1, and if not, the next signal is waited for. Then, when the signal of the second step is input, this time is displayed on the pre-count display section 17 to indicate that it is the second step (C in FIG. 3), and this is repeated to set the pre-count value to N1 (5 in FIG. 3). If it becomes larger, the main count display section 16 starts the display of 0 steps up to N1 + 1 (here, 6). If the pre-count value does not reach N1 + 1 and the next signal does not enter even after the walking end determination time Tstop has elapsed after the input of a certain signal, the pre-count value is set to 0.
And the display of the main count display section 16 remains at 0. The pre-count display section 6 has a configuration in which a plurality of bar-shaped displays are arranged in a line as described above, and the bar-shaped displays that are lit as the count progresses are sequentially shifted. After the display on the unit 16 is started, by continuing the display on the pre-count display unit 17, the above-described operation mode is switched, and the display on the main count display unit 16 becomes something other than the number of steps. Also,
This is so that the user can determine whether or not counting is in progress. It goes without saying that bar-type displays may be stacked vertically to form a bar graph. Then, if the walking is stopped, the main count display unit 16 leaves the display when detecting this,
By turning off the display of the pre-count display section 17, it is possible to inform the user that the stop of walking has been detected. As shown in FIG. 4, the pre-count display section 17 may display numerical values similarly to the main count display section 16. The display space is small. In this case, it is preferable that the display of the pre-count display section 17 disappears when the step count display on the main count display section 16 is started after the elapse of the walking determination period. While the main count display section 16 accumulates the number of steps, the pre-count display section
17 is displayed from 1 for each walking period, so that the user does not have any complexity in checking the number of steps.

【The invention's effect】

As described above, in the present invention, the number of steps is displayed on the pre-count display section during the determination of whether or not the user is walking. Therefore, it is possible to lengthen the period of the walking determination and perform more accurate step counting.
