It is calculated by the following formula.

  When the sensor device 200 is attached to the bicycle 1, the speed sensor 210 is rotated in the direction of the arrow DR210, and the cadence sensor 220 is rotated in the direction of the arrow DR220. Thereby, the space | interval of the speed sensor 210 and the magnet 3A and the space | interval of the cadence sensor 220 and the magnet 4A are adjusted.

  By appropriately adjusting the above interval, it is possible to appropriately detect the passage of the magnet 3A by the speed sensor 210 and the passage of the magnet 4A by the cadence sensor 220.

  In the example of FIG. 2, a wireless device that wirelessly transmits information obtained by the sensor device 200 to the display device main body 100 is shown. However, the display device main body 100 and the sensor device 200 are connected by a cable. A wired type device may be used.

  FIG. 3 is a view showing a state in which the main body of the display device is attached to a fixture for fixing the display device main body to the bicycle. Moreover, FIG. 4 is a figure which shows the state after attaching a display apparatus main body to a fixing tool.

  With reference to FIGS. 3 and 4, the display device main body 100 is attached to the bicycle 1 via a fixture 300. The fixture 300 includes a fixture main body 310, a band 320, an engagement portion 330, and a rotation operation portion 340. The display device main body 100 is slid in the direction of the arrow in FIG. 3, and the engagement portion 100A in the display device main body 100 and the engagement portion 330 in the fixture 300 are engaged, whereby the display device main body 100 is fixed to the fixture 300. Mounted on.

  3 and 4, the fixture 300 is a worm gear type fixture having a rotation operation unit 340. That is, the band 320 can be tightened or loosened by rotating the rotation operation unit 340.

  The engaging portion 330 may be formed separately from the fixture main body 310 and detachable from the fixture main body 310. In this case, if the engagement tool 330 is formed in a substantially square shape and can be attached to the fixture main body 310 after being rotated by 90 °, the mounting direction of the display device main body 100 with respect to the fixture main body 310 can be appropriately changed.

  In the example shown in FIG. 5, the display device main body 100 is attached to a bar 400 (for example, a stem) extending in the front-rear direction of the bicycle 1. It is also possible to attach the main body 100.

  In the present specification, the display device main body 100 and the sensor device 200 as described above are collectively referred to as a “cycle computer”. By fixing the cycle computer to the bicycle, the driver can visually recognize various information displayed on the display device main body 100 when the bicycle is running.

  The information that can be visually recognized by the driver includes information on travel time, travel distance, time, average speed, maximum speed, and the like in addition to the information on the travel speed and cadence described above. That is, the information displayed on the display device main body 100 includes information measured by the sensor device 200 and information originally stored in the display device main body 100.

  By the way, the operation of the display device main body 100 has two modes, “auto mode” and “manual mode”. In the “auto mode”, the riding time is not measured while the bicycle is stopped. In the “manual mode”, the ride time can be manually turned ON / OFF by the rider.

  For example, when the cycle computer is attached to the bicycle for the first time, for example, it is necessary to input the tire circumference of the bicycle to which the computer is attached, the current time, etc., into the display device main body 100. The tire circumference is used to calculate a travel speed, a travel distance, and the like from the measurement result of the sensor device 200 described above.

  In the present specification, the operation for the input is referred to as “setting”, and a device for performing this setting is referred to as “setting device”.

  Next, the setting device according to the present embodiment will be described with reference to FIGS. FIG. 6 is a block diagram for explaining the function of the setting device, and FIGS. 7 and 8 are front views of the setting device. FIG. 7 shows a state where the display device main body 100 is not attached, and FIG. 8 shows a state where the display device main body is attached.

  Referring to FIG. 6, setting device 500 according to the present embodiment performs “setting” of display device main body 100 described above, and includes input unit 510, CPU 520, display control unit 530, and display. Unit 540, storage unit 550, carrier wave generation unit 560, modulation unit 570, and output unit 580. These are provided on or in the housing 590 shown in FIGS.

  As shown in FIG. 6, the display device main body 100 includes an input unit 110, a demodulation unit 120, an information determination control unit 130, a manual input unit 140, a setting management control unit 150, and a speed measurement control unit 160. Including. The input unit 110 is the same as the part that receives a signal from the sensor device 200.

  As shown in FIG. 7, the housing 590 of the setting device 500 has an attachment portion 591 for attaching the display device main body 100. As shown in FIG. 8, the display device main body 100 is engaged with the attachment portion 591. Thus, the output unit 582 of the setting device 500 and the input unit 112 (see FIG. 6) of the display device main body 100 are connected. The output unit 582 and the input unit 112 are electrodes formed on the surfaces of the setting device 500 (housing 590) and the display device main body 100, respectively.

  However, the communication between the setting device 500 and the display device main body 100 is not limited to the wired method in which the setting device 500 and the display device main body 100 are physically connected to each other as described above. It may be based on a wireless system in which the apparatus main body 100 is not physically connected to each other. In this case, the output unit 581 of the setting device 500 and the input unit 111 of the display device main body 100 are used.

  Further, a signal may be sent from one setting device 500 to a plurality of display device main bodies 100. In this case, a plurality of display device main bodies 100 can be set simultaneously.

  Referring to FIG. 6 again, input unit 510 is typically configured with buttons (see FIGS. 7 and 8) provided on housing 590 of setting device 500. In other words, predetermined information is input to the setting device 500 by pressing a button on the housing 590 which is the input unit 510.

  The predetermined information includes, for example, the current time, the tire circumference of the bicycle that fixes the display device main body 100, the type of the display device main body 100, the operation mode of the display device main body 100 (the above-described “auto mode” and “manual Mode ”), the language displayed on the display device main body 100, the unit for displaying the traveling speed and the traveling distance (km, miles, etc.), the cumulative traveling distance so far, and the like.

  CPU 520 includes an information management unit 521 and a transmission information creation unit 522. Display control unit 530 controls information to be displayed on display unit 540 based on the signal received from information management unit 521. The display unit 540 can display predetermined information input from the input unit 510. The display unit 540 is typically a liquid crystal display device formed on a housing 590 (not limited to a liquid crystal as shown in FIGS. 7 and 8), and may be a display device of another type. ).

  Storage unit 550 includes a first portion 551 and a second portion 552. The first portion 551 stores information related to the date and time (current time), and the second portion 552 stores other information (for example, “model of the display device main body 100” described above, “display on the display device main body 100”). ”Language”, “unit for displaying travel speed and travel distance”, etc.) are stored.

  When setting the display device main body 100 using the setting device 500, the information management unit 521 reads out information stored in the first portion 551 and the second portion 552 in the storage unit 550 and displays the information on the display unit 540. . The operator performs an operation of selecting an appropriate item from the “plurality of options” described above via the input unit 510 while confirming the display content on the display unit 540. That is, in the setting device 500, one of “a plurality of options” can be input from the input unit 510 as predetermined information.

  In addition, when the information regarding the date and time stored in the first portion 551 of the storage unit 550 is not accurate, it is possible to input correct date and time information via the input unit 510. Information such as “tire circumference” and “cumulative mileage so far” is directly input from the input unit 510.

  That is, the information transmitted from the setting device 500 to the display device main body 100 is typically the information (first information) originally stored in the setting device 500 and the “ Information selected from a plurality of options ”(second information) and information (third information) input from the input unit 510 when setting the display device main body 100 are included.

  More specifically, the first information originally stored in the setting device 500 is, for example, the current time, and the second information selected from the “plural choices” originally stored in the setting device 500 is For example, a unit for displaying the model of the display device main body 100, the operation mode of the display device main body 100, the language displayed on the display device main body 100, and the travel speed and travel distance. The 3rd information done is the tire circumference of the bicycle which fixes display device main part 100, and the accumulated mileage so far, for example.

  Note that the information transmitted from the setting device 500 to the display device main body 100 does not necessarily include all of the first to third information. For example, there is no first information, and the second and third information. Only the first information may be included, or the second information may not be included, and only the first and third information may be included. The third information may not be included, and the first and second information may be included. Only the information may be included. Furthermore, it may include only one of the first to third information.

  When performing communication by the above wireless method, the first to third information collected by the information management unit 521 is transmitted to the modulation unit 570 via the transmission information creation unit 522 in the CPU 520. Note that a carrier wave is sent from the carrier wave generator 560 to the modulator 570. Modulation section 570 modulates the carrier wave based on the information transmitted from CPU 520. As a result, a signal that can be transmitted to the display apparatus main body 100 via the output unit 580 is generated.

  The input unit 111 of the display device main body 100 receives the signal transmitted from the output unit 581. The signal received by the input unit 111 is demodulated by the demodulation unit 120. The information extracted by demodulation is determined by the information determination control unit 130 as to whether or not the information is damaged. If there is no damage, the information is stored in the setting management control unit 150 and the setting is completed.

  On the other hand, when performing communication using the wired system, the first to third information collected by the information management unit 521 is transmitted to the output unit 582 via the transmission information creation unit 522 in the CPU 520. The information is transmitted from the output unit 582 of the setting device 500 to the input unit 112 of the display device main body 100. Information transmitted to the input unit 112 is sent to the information determination control unit 130. The information determination control unit 130 determines whether or not information is damaged. If there is no damage, the information is stored in the setting management control unit 150, and the setting is completed in the same manner as in the wireless system.

  The setting management control unit 150 transmits predetermined information to the measurement control unit 160 based on information from the information determination control unit 130. Thereby, the setting of the display device main body 100 is completed. The measurement control unit 160 calculates a traveling speed and the like based on information input from the setting management control unit 150 at the time of setting and information measured by the sensor device 200 at the time of traveling, and is displayed on a display unit (not shown). To display.

  The display device main body 100 is provided with a manual input unit 140. The setting management control unit 150 can also capture information input from the manual input unit 140 and transmit the information to the measurement control unit 160. In this manner, the display device main body 100 can be set by inputting information from the manual input unit 140.

  Since the display device main body 100 is fixed to a bicycle, it is required to be downsized. Therefore, the manual input unit 140 provided on the display device main body 100 is inevitably simpler and smaller than the input unit 510 of the setting device 500. Therefore, inputting information from the manual input unit 140 and setting the display device main body 100 is a complicated operation for the user. If the setting of the display device main body 100 is performed by the setting device 500 according to the present embodiment, such a complicated work need not be performed.

  The setting device 500 according to the present embodiment has the following features in addition to the configuration described above. That is, setting device 500 according to the present embodiment can diagnose whether or not a predetermined function (for example, a speed display function) of display device main body 100 is normal.

  Suppose that a problem occurs in which the traveling speed is not displayed during traveling, even though the cycle computer is attached to the bicycle. In this case, possible causes include failure of the display device main body 100, failure of the sensor device 200, failure of a cable (in the case of a wired system) connecting the display device main body 100 and the sensor device 200, and the like.

  However, it is often difficult to determine the cause of this defect based only on the appearance. Therefore, if the above-described problem occurs, it is necessary to inspect the inside of the display device main body 100 regardless of whether the display device main body 100 is defective or not.

  On the other hand, the setting device 500 according to the present embodiment diagnoses whether or not the display function of the display device main body 100 is normal, so that the above-described malfunction is due to the failure of the display device main body 100 or otherwise. It is possible to easily and quickly determine whether it is caused by the problem.

  More specifically, in the state where the display device main body 100 is attached to the setting device 500 according to the present embodiment, when the input unit 510 inputs that the “diagnosis” is to be performed, the information is stored in the information management unit 521. To the transmission information creation unit 522.

  Then, the transmission information creation unit 522 creates simulation information about the traveling speed (more specifically, simulation information about the period in which the magnet 3A passes in front of the speed sensor 210) in order to perform the “diagnosis”. The data is sent to the output unit 580 via the modulation unit 570.

  If the function of the display device main body 100 is normal, the simulation information about the traveling speed sent to the output unit 580 is taken into the display device main body 100 from the input unit 110, and a predetermined speed is displayed on the display device main body 110. (This numerical value varies depending on the set tire circumference).

  Thereby, it is confirmed that the speed display function of the display device main body 100 is normal, and if there is a problem that the traveling speed is not displayed during traveling, the problem is a part other than the display device main body 100. It can be determined that this is due to a failure of the sensor device 200 or the cable connecting the display device main body 100 and the sensor device 200.

  Conversely, if no speed is displayed on the display device main body 100 despite the execution of the “diagnosis” function, it can be determined that the speed display function of the display device main body 100 is not normal.

  Thus, according to the setting device 500 according to the present embodiment, by providing the “diagnosis” function, it is diagnosed whether or not the display function of the display device main body 100 is normal, and is generated in the cycle computer. It is possible to assist in determining whether the problem is caused by a failure of the display apparatus main body 100 or a cause other than that.

  In the above example, the diagnosis of the speed display function has been described. Needless to say, the diagnosis of other information display functions such as the cadence display function can be performed in the same manner.

  The above contents are summarized as follows. That is, the setting device 500 according to the present embodiment is for setting the display device main body 100 attached to a bicycle capable of displaying predetermined information such as the traveling speed and cadence of the bicycle taken in from the outside (sensor device 200). An output unit 580 that outputs predetermined information to the display device main body 100, an input unit 510 that can input predetermined information transmitted to the display device main body 100 via the output unit 580, and an input unit And a CPU 520 as an “information processing unit” that processes predetermined information input from 510. The CPU 520 can create a predetermined simulation signal related to information taken into the display device main body 100 from the sensor device 200, and the predetermined signal is transmitted to the display device main body 100 via the output unit 580.
