Abstract
The invention discloses a height reminding method based on GPS; a front road surface height condition is acquired through a GPS positioning system, and the method includes the following steps: a, pre-setting a distance reminding scope; b, when a target reminder appears at a front road surface, determining whether the target reminder is on a driving route, and if the target reminder is on the driving route, executing a step c, otherwise executing a step h; c, acquiring height information and position m information by a GPS map; d, positioning a current position n by the GPS positioning system, and reading current height information and position information by the GPS map; e, calculating the distance between the m and the n and the height of the target reminder to the current position; f, determining whether the distance between the m and the n is less than the preset distance, and if the distance is less than the preset distance, executing a step g, otherwise executing the step h; g, carrying out voice broadcast of the distance and the height of the target reminder to the current position; and h, allowing voice broadcast not to be performed.
Description
[technical field]
The present invention relates to a kind of height based reminding method based on GPS.
[background technology]
A kind of time-honored vehicles from traveling, in the middle of bicycle evolution, in order to reduce expending of foot-operated fatigue and muscle power, thus start to occur multi-speed bicycle, particularly current a lot of mountain bikes on the market all have multi-stage transmission mechanism, can realize multi-change speed function.Existing multi-speed bicycle is all utilize manually to carry out speed change switching; the following problem of these multi-speed bicycle ubiquities: cyclist is in ride otherwise be completely cured and manually shift gears the adjustment speed of a motor vehicle according to road conditions; often there will be gearshift time more late situation; owing to forgetting; to have little time or special road conditions may cause speed change excessively late for opportunity, cause speed change smooth or damage speed change system.
The car-mounted orientator used on the market at present, has the function of navigation, location, how this positioning function is applied to obstacle height, and in position reminding aspect, can carry out speed change in advance to facilitate cyclist and prepare, be the problem to be solved in the present invention.
[summary of the invention]
Fundamental purpose of the present invention is to provide a kind of height based reminding method, for providing slope, the bridge equal altitudes on pavement behavior and road surface in advance from travelling fan, facilitating cyclist to carry out speed change in advance and preparing.
In order to achieve the above object, the invention provides a kind of height based reminding method based on GPS, obtain road surface ahead height situation by GPS positioning system, comprise the following steps:
A. preset distance reminds scope;
B. when target reminder appears in road surface ahead, judge target reminder whether on travel route, if on travel route, then perform step c, otherwise perform step h;
C. its elevation information and position m information thereof is obtained by GPS map;
D.GPS positioning system positions current location n, reads present level information and positional information by GPS map;
E. distance between m, n and target reminder is calculated to the height of current location;
F. judge whether the distance between m, n is less than the distance preset, and if so, then performs step g, otherwise perform step h;
G. to the height of current location, voice broadcast is carried out to above-mentioned distance and this target reminder;
H. voice broadcast is not carried out.
Especially, the elevation information of target reminder is indicated in described GPS map.
Compared with prior art, the present invention is based on the height based reminding method of GPS, GPS positioning system is utilized to combine with GPS map, the elevation information of the barrier such as slope, bridge is forecast in predetermined distance range, make cyclist can carry out speed change in advance to prepare, prevent from having little time or special road conditions cause speed change excessively late for opportunity, cause speed change smooth or damage the situations such as speed change system.
[accompanying drawing explanation]
Fig. 1 is the functional-block diagram of the height based reminding method that the present invention is based on GPS.
[embodiment]
Refer to shown in Fig. 1, the present invention is based on the height based reminding method of GPS, for obtaining road surface ahead height situation by GPS positioning system, indicate the elevation information of target reminder in described GPS map, the method comprises the following steps:
Step 10: preset distance reminds scope; Cyclist before the use can according to actual needs, and being set in advance in distance how far has during target reminder and carry out voice reminder, and such as, can be set in advance within the scope of 100m and carry out voice broadcast, described target reminder is slope, bridge etc.
Step 20: when target reminder appears in road surface ahead, obtains its elevation information and position m information by GPS map; When slope or bridge appear in front, obtain slope or the sea level elevation of bridge and the geographic coordinate of this slope or bridge by GPS map.
Step 30: judge target reminder that front occurs whether on travel route, if on travel route, perform step 40, otherwise perform step 80.
Step 40:GPS positioning system positions current location n, reads present level information and positional information by GPS map; GPS positioning system obtains current geographical location information and sea level elevation.
Step 50: obtain distance between m, n and target reminder to the height of current location; By the difference of GPS map calculation target reminder and current location sea level elevation between the two, namely target reminder is to the height of current location.
Step 60: judge whether the distance between m, n is less than the distance preset, if so, then performs step 70, otherwise, perform step 80.
Step 70: to the height of current location, voice broadcast is carried out to above-mentioned distance and this target reminder
Step 80: do not carry out voice broadcast.
The above; be only the specific embodiment of the present invention, but protection scope of the present invention is not limited thereto, is anyly familiar with those skilled in the art in the technical scope that the present invention discloses; change can be expected easily or replace, all should be encompassed within protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion with the protection domain of claim.
