Description
Technical field
The utility model relates to a kind of odometer, more particularly, relates to a kind of walking odometer.
Background technology
How many steps, common passometer can only show left, and can not inform the length of distance, can not indicate the orientation of departure place.And the utility model utilizes the gps satellite location technology, dynamically measures and demonstrate the length of the arbitrary curve distance that the carrier experiences, and also can inform the distance and bearing of user between starting point intuitively.The people that it is particularly suitable for outdoor exercises use, no matter be walking, run, by bike or take the journey motion, though distance length, no matter also speed speed can both reach identical measuring accuracy.
The utility model content
Technical problem to be solved in the utility model provides a kind of portable mileage and measures and the departure place indicating device, where the path length that is experienced can both be accurately measured and demonstrate no matter go to, the walking odometer of the azimuth-range of the departure place of setting before the user can also be told simultaneously.
In order to solve the problems of the technologies described above, the utility model has adopted following technical scheme: the utility model comprises shell, display screen, button, thumb wheel, the circuit board that is installed on enclosure and battery; GPS module, chip microprocessor, mu balanced circuit and charging circuit also are installed on the circuit board; Also be equipped with on the circuit board with LCDs backlight, pushbutton switch and thumbwheel switch, battery is wired on the circuit board; Circuit board and battery are installed in enclosure, and the window that the display screen of installing on it sees through the shell front reveals; Button is contained on the shell, directly contacts with pushbutton switch on the circuit board, and the axle of thumb wheel is inserted in the axis hole of thumbwheel switch, and the thumb wheel edge exposes shell.
The utility model principle of work is as follows: the GPS module constantly receives the positioning signal that comes from gps satellite, and produces serial data output; Chip microprocessor receives this serial data and analyzes and just can obtain current earth surface coordinate data; The state of the continuous review button switch of microprocessor, after finding that pushbutton switch is pressed, microprocessor just is kept at current coordinate data in its inner storer, as " departure place "; The GPS module is constantly sent new coordinate data, and microprocessor is also constantly received new coordinate data, and the data of preserving before constantly following compare and calculate, and constantly refresh accumulative mileage and orientation, departure place, range information; Microprocessor is also constantly checked the state of thumbwheel switch, and decides which result of demonstration according to its state.Pushbutton switch is the back lighting that is used for opening or close LCDs.Whole device is powered by battery.The corresponding software of operation carries out data processing, mathematical operation and control button and display device in the microprocessor.
When the utility model uses, click START button and just set positions at that time can be " departure place ", after this just constantly receive the new coordinate data that comes from gps satellite, and the continuous cumulative length that calculates the distance that is experienced, also calculate simultaneously azimuth-range, and show with literal in real time from the departure place.
The beneficial effects of the utility model: volume small volume and less weight, use easy to operately, can constantly receive the new coordinate data that comes from gps satellite, and constantly calculate the cumulative length of the distance that is experienced, also calculate simultaneously azimuth-range, and show with literal in real time from the departure place.It can be used for the outdoor exercises quantitative statistics, also can prevent to get lost in the unfamiliar place or wander away.
