Abstract
The novel track deviation warning method based on geographical coordinate that the invention discloses a kind of.Suitable for track deviation warning function of the mobile device in predetermined region, its essence is a kind of methods that quick and precisely reflection smart machine positions in real time.Method includes：1）The acquisition of predetermined geographic coordinate and fence area；2）The anchor point fence in predetermined region is obtained according to equipment geographical coordinate；3) real-time geographic coordinate is judged whether in fence area, so that it is determined that whether equipment deviates from presumptive area.Compared to the conventional method for directly obtaining and determining from third party's map to deviate track, the compatible a variety of satellite positioning coordinate systems of this method, and without under the premise of downloading a large amount of offline map data and integrated third party's map SDK, realize more rapidly, more acurrate track deviation warning function, equipment vast resources is saved, the therefrom of third party's map SDK is breached.
Description
Technical field
The present invention relates to the running fix field of smart machine and intelligent monitoring development field, in particular to a kind of intelligence is set
The alarm method of standby motion track deviation, so that the autonomous correcting function of smart machine can be realized.
Background technique
Currently, digital earth technology becomes better and approaching perfection day by day, it is raw that various extraordinary Intelligent mobile equipments is widely used in daily life
It produces in environment, such as intelligent inspection robot and instantly burning hot unmanned.This is to geo-location, path planning, and geography
More stringent requirements are proposed for fence area inspection technology.Following problem be exactly single large and complete geographic positioning technology without
Method meets diversified application scenarios.How the planning of light quickly and accurately realizing route and track deviation warning, become not
Avoidable technical problem.
Traditional method, mainly integrated third party's map SDK, such as Amap, Baidu map etc. are getting equipment
After GPS coordinate, determine whether equipment deviates presumptive area by inquiry network or prepackage offline map.This method exists as follows
Problem：
1）It is limited to third party SDK, is not available other satellite navigation systems, such as domestic dipper system, Russian Glonass
With European Galileo satellite navigation system；
2）Integrated third party SDK, has operating system and clearly limits, be unable to satisfy the work requirements of dedicated embedded mini system,
And increase system operation expense；
3）There is delay in network inquiry, in network signal difference, be unable to satisfy real-time response function；
4）Inquiry offline map then needs to download the off-line data packet of big file, for the equipment set to running track, exists
Design excessively, reduces response efficiency.
Summary of the invention
For overcome the deficiencies in the prior art, the present invention provides a kind of novel track deviation warning based on geographical coordinate
Method realizes the track deviation warning strategy of more quick, more accurate and low operation expense.
The present invention claims the goal systems of processing need to meet condition：Device hardware includes satellite positioning mould group, and system branch
Hold real-time query current geographic coordinate.
The technical solution adopted by the present invention to solve the technical problems is：
1）Equipment generates multistage geography fence according to algorithm by the track geographical coordinate point prestored, is cached to using local；
2）The real-time geographic coordinate of system queries gets anchor point fence area by comparing trajectory coordinates；
3）Pass through algorithm, it may be determined that real-time geographic coordinate is whether in anchor point fence area, therefore, it is determined that whether equipment has been sent out
Track deviation is given birth to.
The beneficial effects of the invention are as follows：Mobile device fast and accurately can determine whether to have occurred track and be deviated into,
And then certain correction is made to route or mobile posture.A kind of novel track deviation warning side based on geographical coordinate of the present invention
Method breaches single satellite navigation system compared to conventional method, gets rid of the limitation of operating system platform, reduces and is
The complexity of system has saved the operation expense of system.
Detailed description of the invention
Present invention will be further explained below with reference to the attached drawings and examples.
Fig. 1：Track regions fence schematic diagram of the invention.
Fig. 2：Geography of the invention（GPS）Position schematic diagram.
Fig. 3：Bias determining schematic diagram of the invention.
Specific embodiment
Below in conjunction with drawings and examples, the present invention will be described in further detail.It should be appreciated that described herein
Specific examples are only used to explain the present invention, is not intended to limit the present invention.
The novel track deviation warning method based on geographical coordinate that the present invention discloses a kind of, as shown in Figure 1：Equipment prestores
Trajectory coordinates point A (lngA, latA), B (lngB, latB), C (lngC, latC), D (lngD, latD), according to maximum deflection difference value
X generates geographic area fence.
The novel track deviation warning method based on geographical coordinate that the present invention discloses a kind of, Fig. 2 illustrate equipment in GPS
Positioning system obtains the process for being currently located fence：When equipment real time GPS coordinate is X1, trajectory coordinates point is prestored by comparison
A, B, C, D, it is known that current geography fence region recently is the corresponding fence area A to B anchor point A；When equipment real time GPS coordinate is
When X2, trajectory coordinates point A, B, C, D are prestored by comparison, it is known that current geography fence region recently is corresponding B to the C of anchor point B
Fence area.
The novel track deviation warning method based on geographical coordinate that the present invention discloses a kind of, Fig. 3 is illustrated to exist in equipment
After GPS positioning system gets fence area, determine equipment real time GPS whether the process in fence area.According to ray method
It is found that the ray and polygon drawn have odd number intersection point, such as point X2 (lng2, lat2) when point is in polygonal internal;When
For point in outside of polygon, the ray and polygon drawn have even number intersection point, such as point X1 (lng1, lat1), X3 (lng3,
lat3)。
Through the invention, a kind of novel track deviation warning method based on geographical coordinate, it is more to be compatible with GPS, Beidou etc.
Kind global position system coordinate, gets rid of limitation of third party's map SDK to operating system platform, significantly reduces the complexity of system
Degree, has expanded the application scenarios of embedded custom-built system, has promoted exploitation and production efficiency.
Superior embodiment of the invention has shown and described in above description, as previously described, it should be understood that the present invention is not office
Be limited to form disclosed herein, should not be regarded as an exclusion of other examples, and can be used for various other combinations, modification and
Environment, and can be changed within that scope of the inventive concept describe herein by the above teachings or related fields of technology or knowledge
It is dynamic.And changes and modifications made by those skilled in the art do not depart from the spirit and scope of the present invention, then it all should be appended by the present invention
In scope of protection of the claims.
