Description

  The present invention relates to a bicycle environmental protection contribution measuring device that is used by being mounted on a bicycle and measures the contribution of environmental protection.

Conventionally, the rotational speed of a wheel is measured by a magnet attached to a spoke of a wheel and a sensor attached to a fork, and the travel distance and speed of the bicycle are obtained from the rotational speed and a preset wheel diameter or circumference. A cycle computer for displaying is known (see, for example, Patent Document 1).
In addition, due to environmental considerations in recent years, it is also possible to understand how much load is placed on the environment by moving in a car or riding an elevator in daily life by converting it to a CO ₂ emission value. It is known (see, for example, Patent Document 2).

Bicycles are re-recognized by the fact that they can move only by their own power, unlike transportation systems that emit CO ₂ , such as cars, buses, and trains. If moved by the bicycle, and that can reduce the CO ₂ at the time of moving the same distance in a car, it is increasing even companies and municipalities for reducing reduce the amount of CO ₂ as an eco points representing environmental contribution. Eco-points can be used as a substitute for currency within the community, and environmental considerations are promoted through the motivation of eco-points.

However, there are concerns about illegally earning eco-points. For example, the travel distance of the bicycle measured by the method described in Patent Document 1 is derived only by the rotation of the wheel. Is stored in the memory of the cycle computer. When converted to the eco point with the distance actually there is a problem that can be fraudulently acquiring the reduction eco point CO ₂ using a machine for discharging the CO _2.

A processing unit 120 that performs determination of whether or not the vehicle has moved, eco-point calculation processing, and the like is provided.

Here, the eco point is a numerical value representing the degree of contribution to environmental protection in relation to the travel distance of the bicycle. A unit eco point representing the degree of environmental protection contribution per unit travel distance of the bicycle is stored in the RAM 116 as setting data. An eco point corresponding to the travel distance is calculated by multiplying the travel distance of the bicycle by the unit eco point.
The processing unit 120 executes a program stored in the ROM 115, thereby moving the moving distance / speed calculating unit 102, the current position calculating unit 103, the GPS distance / speed calculating unit 104, the effective moving distance determining unit 105, and an initial value setting unit. 106, an eco point calculation unit 107, an effective movement distance counting unit 108, and a GPS reception control unit 118.

The GPS receiving unit 101, the current position calculating unit 103, the GPS distance / speed calculating unit 104, and the GPS reception control unit 118 constitute a GPS receiver.
The wheel rotation speed detection unit 100 constitutes a wheel rotation speed detection unit, the movement distance / speed calculation unit 102 constitutes a movement distance calculation unit, the ROM 115 and the RAM 116 constitute storage means, and the GPS reception control unit 118 The GPS control means is configured. The GPS reception unit 101, the current position calculation unit 103, the GPS distance / speed calculation unit 104, and the GPS reception control unit 118 constitute a GPS information calculation unit. The current position calculation unit 103 and the GPS distance / speed calculation unit 104 constitute a GPS calculation unit. Further, the effective movement distance determination unit 105, the initial value setting unit 106, the eco point calculation unit 107, and the effective movement distance counting unit 108 constitute an eco point calculation unit.

  As shown in FIG. 2, the wheel rotation speed detection unit 100 includes a magnet 100b attached to the spoke 201 of the bicycle wheel and a reed switch 100a attached to the fork 200 of the vehicle body. When the wheel rotates and the magnet 100b approaches the reed switch 100 below a predetermined distance, the reed switch 100 is turned on and a rotation signal is output. When the magnet 100b moves away from the reed switch 100 by a predetermined distance or more, the reed switch 100 is turned off. It is configured to be. The measuring device main body 117 is detachably attached to the handle portion of the bicycle.

FIG. 4 is a flowchart of the bicycle environmental protection contribution measuring apparatus according to the embodiment of the present invention, and mainly shows the processing of the processing unit 120.
In FIG. 4, the processing unit 120 of the measuring apparatus main body 117 determines the operation mode designated by the input unit 114 (step S1). If the operation mode is the initial value setting mode, the user can Alternatively, the circumference data related to the circumference of the wheel such as the diameter and the unit eco point (the number of eco points per unit travel distance of the bicycle) are input to the initial value setting unit 106 via the input unit 114 (steps S12 and S13). ). This value is stored in the RAM 116 as setting data.

When the mode is the measurement mode, the user operates the input unit 114 to give a measurement start instruction and starts measurement (step S2).
In the GPS receiver, the GPS receiver 101 starts measurement upon receiving a measurement start instruction from the input unit 114, obtains the current position by the current position calculator 103 based on the received GPS position information (step S3), and GPS The distance / speed calculation unit 104 calculates the travel distance and speed of the bicycle obtained by the GPS function (step S4).
On the other hand, when detecting the rotation pulse generated by the rotation of the wheel (step S5), the wheel rotation speed detection unit 100 inputs a rotation signal corresponding to the detected rotation pulse to the movement distance / speed calculation unit 102. The travel distance / speed calculation unit 102 obtains the travel distance and speed of the bicycle per predetermined time based on the circumference data preset in the RAM 116 (step S6).

  In the effective travel distance determination unit 105, the travel distance and speed of the bicycle determined by the travel distance / speed calculation unit 102 at a predetermined time from the number of rotations of the wheels, and the travel distance of the bicycle determined at the GPS receiver side at the predetermined time. And the moving speed is compared to perform an effective moving distance determination process (step S7). If the difference between the two is equal to or smaller than a predetermined determination value, it is determined that the bicycle is truly moving, and the wheel rotation speed detection unit It is determined that the travel distance obtained from the rotation signal from 100 is valid, and the cumulative travel distance up to the present time is calculated by adding to the travel distance so far stored in the RAM 116 by the effective travel distance counting unit 108. (Steps S8 and S10). The movement distance calculated by the effective movement distance counting unit 108 is displayed on the display unit 113 by driving the display driving circuit 112 under the control of the processing unit 120 (step S11).

On the other hand, when the difference between the two is larger than the predetermined determination value, it is determined that the bicycle has not moved, and the movement distance obtained from the wheel rotation signal is determined to be an illegally obtained value and measured this time. The travel distance of the bicycle is set to 0 (step S9).
The determination value for determining whether or not the bicycle has truly moved as described above is stored in advance in the ROM 115 as data.
The determination value may be a difference in moving distance per unit time. The determination value may be an instantaneous speed value. Moreover, the said determination value is good also as a moving average value for every fixed area length. The determination can be made based on at least one of these determination values.
In addition, at least one of these determination values is adopted, and the movement is determined to be true when the fluctuation of the period of the detection signal output from the wheel rotation speed detection unit 100 is equal to or greater than a predetermined value. Also good. In the case of true movement, the period of the detection signal generally fluctuates within a predetermined range. If the fluctuation range is equal to or less than the coincidence value, there is a possibility that the wheel is rotated using a machine or the like. is there.

When the user arrives at the destination, the user presses the measurement end button of the input unit 114 (step S14). The total effective moving distance from the start to the end of measurement and the eco point value corresponding to the effective distance are calculated and displayed on the display means 113 (step S15). The total effective travel distance and eco point value are stored in the RAM 116.
The RAM 116 stores the movement distance per unit time measured from the GPS position data and obtained by the GPS distance / speed calculation unit 104 from the measurement start to the measurement end in the RAM 116 together with the measurement time. Similarly, the movement distance and measurement time per unit time obtained by the movement distance / speed calculation unit 102 are stored. The former is the travel distance measured by the GPS function, and the latter is the travel distance measured based on the number of rotations of the bicycle wheel.

  After the measurement is completed, the user removes the measuring device main body 117 from the bicycle main body and connects it to the dedicated terminal device 300 shown in FIG. The eco point card 302 is inserted into the card insertion slot 301 of the dedicated terminal device 300. The measurement device 117 is set to the data output mode, the dedicated terminal device 300 is operated, and the respective movement distances and measurement times calculated from the signals obtained from the measurement device 117 by the GPS receiver 101 and the wheel rotation detector 100. Is transmitted to the dedicated terminal 300 via the data communication unit 109 and the data cable 302 (steps S16 and S17).

The dedicated terminal 300 compares the two types of travel distances with the measurement time, determines whether the travel was on a bicycle, adds only the distance determined to be travel on a bicycle, calculates the effective travel distance, and converts it to an eco point. .
Here, the determination of whether or not the movement is by bicycle and the conversion to the eco-point are performed by the measuring device main body 117 and also by the dedicated terminal 300 side. It is preferable to carry out at 300 (mainly in the store). In this case, the effective travel distance and the eco point displayed on the measuring device main body 117 are only a guide.

Further, when the store lends the measuring device main body 117 itself, since the value determined by the measuring device main body 117 is reliable, the determination at the dedicated terminal 300 is not necessary.
The effective travel distance converted into the eco point in the dedicated terminal 300 is deleted from the measurement apparatus main body 117 after the measurement data is output in order to prevent reuse (S18, S19).
The eco points calculated by the dedicated terminal 300 as described above are stored in the dedicated point card 302 and used.

On the other hand, when the moving speed of the bicycle obtained by the wheel rotation speed detection unit 100 reaches 0 for a certain time, it is determined that the bicycle has stopped, and at least the GPS receiving unit 101 in the GPS receiver is driven intermittently. Switch. After that, when the moving speed obtained by the wheel rotation speed detection unit 100 becomes other than 0 again, the driving of the GPS receiving unit 101 is returned to the continuous driving.
That is, when the movement distance / speed calculation unit 102 detects that the bicycle movement speed obtained from the rotation signal detected by the wheel rotation number detection unit 100 has reached zero for a predetermined time, at least the operation of the GPS reception unit 101 is performed. The GPS reception control unit 118 is instructed to control the intermittent operation. In response to the intermittent operation control instruction, the GPS reception control unit 118 controls the GPS reception unit 101 to intermittently perform a reception operation at a predetermined period.

Thereafter, when the moving distance / speed calculating unit 102 detects that the moving speed of the bicycle obtained from the rotation signal detected by the wheel rotation number detecting unit 100 is other than 0, at least the operation of the GPS receiving unit 101 is continued. The GPS reception control unit 118 is instructed to control the operation. In response to the continuous operation control instruction, the GPS reception control unit 118 controls the GPS reception unit 101 to continuously perform the reception operation.
Thereby, it is possible to reduce waste of power consumption by the GPS reception function.

  As described above, according to the bicycle environment protection contribution measuring apparatus according to the embodiment of the present invention, the wheel rotation speed detection unit 100 detects the rotation of the bicycle wheel and outputs a corresponding rotation signal. The moving distance / speed calculating unit 102 calculates the moving distance of the bicycle in a predetermined time based on the rotation signal and the wheel circumference data set in the RAM. The GPS receiving unit 101 receives GPS position information, the current position calculating unit 103 calculates the current position from the GPS position information, and the GPS distance / speed calculating unit 104 calculates a moving distance at a predetermined time based on the GPS position information. . When the difference between the movement distance calculated by the movement distance / speed calculation unit 102 and the movement distance calculated by the GPS distance / speed calculation unit 104 is within a predetermined range, the eco point calculation unit 107 An accumulated eco point is calculated by obtaining an eco point corresponding to the calculated moving distance.

  Therefore, since it can be determined whether or not the bicycle has truly moved by using the GPS function, when a person turns the wheel illegally using a machine or the like without actually riding the bicycle, It can be determined that the user is not riding a bicycle. Therefore, in this case, since the eco point is not added, it is possible to prevent the eco point from being illegally obtained and to calculate an accurate eco point.

  Various modifications can be made to the above-described embodiment. For example, an interface for performing data communication via a mobile phone is provided, and the movement distance and position information stored in the RAM 116 are transmitted to a dedicated server (not shown) via the interface and the mobile phone (not shown). Then, the server may be configured to calculate an effective travel distance and convert it to an eco point. Even in this case, the user can connect the point card to the dedicated terminal and store the eco point.

  The present invention can be used for various environmental protection contribution measuring devices for bicycles that calculate eco points according to the travel distance of the bicycle.
