Abstract
The utility model discloses a digital odometer device for a bicycle. The digital odometer device comprises a singlechip microcomputer, a keyboard, a liquid crystal display and a wheel rotating speed acquisition device, wherein the wheel rotating speed acquisition device comprises a transmitting phototube, a receiving phototube and an aluminum plate arranged on a rotating shaft of bicycle wheels; the aluminum plate is uniformly distributed with a plurality of small holes along the same circumference; the transmitting phototube and the receiving phototube are respectively arranged at two sides of the aluminum plate; the receiving phototube is used for receiving signals transmitted by the transmitting phototube through all the small holes in the aluminum plate; and the keyboard, the liquid crystal display, the transmitting phototube and the receiving phototube are respectively connected with the singlechip microcomputer. The digital odometer device disclosed by the utility model has the advantages of simple structure, low cost, distinct display, stability and reliability and the like.
Description
Technical field
The utility model relates to the bicycle odometer device, is specifically related to a kind of easy bicycle numeral mileometer device.
Background technology
Bicycle odometer helps the sporter to carry out the motion of moderate exercise or capacity, to reach the optimum efficiency of exercise through reasonably calculating the bicycle running milimeter number.The bicycle odometer majority of selling in the market is mechanical, and the too loaded down with trivial details and mileage value that calculated of its installing/dismounting has too much error.
Summary of the invention
To the defective or the deficiency of prior art, the purpose of the utility model is to provide a kind of automaticity height, measures bicycle numeral mileometer device accurately.
In order to realize above-mentioned task, the utility model adopts following technical scheme to be achieved:
A kind of bicycle numeral mileometer device; It is characterized in that; Comprise single-chip microcomputer, keyboard, LCD and vehicle wheel rotational speed harvester; Said vehicle wheel rotational speed harvester comprises emission phototube, receives photoelectric tube and is installed on the aluminium dish in the cycle wheel rotating shaft, and the same circumference in said aluminium dish upper edge is evenly distributed with a plurality of apertures, said emission phototube with receive the both sides that photoelectric tube is installed on the aluminium dish respectively; And receive photoelectric tube and receive the signal that emission phototube is launched through each aperture on the aluminium dish, said keyboard, LCD, emission phototube and reception photoelectric tube are connected with single-chip microcomputer respectively.
Said single-chip microcomputer adopts the AT89S51 single-chip microcomputer.
Said LCD adopts the SMC1602 LCD.
Said keyboard adopts 4 * 4 keyboards.
After the bicycle numeral mileometer device of the utility model is selected the vehicle of bicycle through keyboard; Under selected vehicle pattern, carry out the collection of signal emission and signal by photoelectric tube; The data that collect are sent into single-chip microcomputer and are handled; Single-chip microcomputer calculates mileage, and shows the mileage of surveying by LCD MODULE.This Design of device has simple in structure, and is with low cost, clear display, advantage such as reliable and stable.
Description of drawings
Fig. 1 is the structural representation of the utility model;
Fig. 2 is the structural representation of the aluminium dish of the utility model.
Below in conjunction with accompanying drawing and embodiment the further explain of doing to the utility model.
Embodiment
With reference to figure 1 and Fig. 2; The bicycle numeral mileometer device of the utility model comprises single-chip microcomputer, keyboard, LCD and vehicle wheel rotational speed harvester; Said vehicle wheel rotational speed harvester comprises emission phototube 2, receives photoelectric tube 3 and is installed on the aluminium dish 1 in the cycle wheel rotating shaft; The same circumference in said aluminium dish 1 upper edge is evenly distributed with a plurality of apertures; Said emission phototube 2 is installed on the both sides of aluminium dish 1 respectively with reception photoelectric tube 3, and receives the signal that photoelectric tube 3 is launched through the reception of the aperture on the aluminium dish 1 emission phototube 2, and said keyboard, LCD, emission phototube 2 and reception photoelectric tube 3 are connected with single-chip microcomputer respectively.Wherein single-chip microcomputer adopts the AT89S51 single-chip microcomputer, and LCD adopts the SMC1602 LCD, and keyboard adopts 4 * 4 keyboards.
After device is selected the vehicle of bicycle through keyboard; Under selected vehicle pattern, carry out the signal emission by emission phototube 2; Receive photoelectric tube 3 receives emission phototube 2 through each aperture on the aluminium dish 1 signal; Accept photoelectric tube 3 and the signal that collects is sent into single-chip microcomputer handle, single-chip microcomputer calculates mileage, and by mileage that liquid crystal display displays is surveyed.
The aluminium dish 1 that is evenly distributed with a plurality of apertures around in the vehicle wheel rotational speed harvester is contained on the axle of bicycle front-wheel; Rotation along with aluminium dish 1; Emission phototube 2 light also pass through or obstructed small holes thereupon; The power that reception photoelectric tube 3 is sensed light changes with the form output of electric signal, and the different speed of a motor vehicle will become the pulse signal of different frequency, and the P3.0 mouth that signal is linked into single-chip microcomputer calculates the bicycle mileage.
SMC1602 LCD, RS wherein connect the P2.0 mouth of single-chip microcomputer, and RW meets P2.1, and E meets P2.2, and D0-D7 connects the P1 mouth of single-chip microcomputer, can realize showing mileage number through program.
8 pins that 4 * 4 keyboards are drawn connect the P0 mouth of single-chip microcomputer, and as output terminal, the I/O mouth that alignment connect can be selected the model of bicycle tyre through keyboard then as input with the I/O mouth of the single-chip microcomputer that column rule connect.
Used electronic devices and components are commercially available known product in the device of the utility model, and those skilled in the art can realize the connection of each electronic devices and components according to the application's technique effect.
