Except purpose described above, feature and advantage, the present invention also has other purpose, feature and advantage.The below is with reference to figure, and the present invention is further detailed explanation.
Description of drawings
The accompanying drawing that consists of the application's a part is used to provide a further understanding of the present invention, and illustrative examples of the present invention and explanation thereof are used for explaining the present invention, do not consist of improper restriction of the present invention.In the accompanying drawings:
Fig. 1 is the composition structural representation block diagram of the preferred embodiment of the present invention.
Embodiment
Below in conjunction with accompanying drawing embodiments of the invention are elaborated, but the multitude of different ways that the present invention can be defined by the claims and cover is implemented.
Referring to Fig. 1, Vehicle Driving Cycle stitch seam leans out line supervisory system of the present invention comprises:
1, position detecting device for the current line truck position that obtains vehicle by the GPS module, and is analyzed the current longitude and latitude that obtains vehicle.
In the present embodiment, position detecting device links to each other with GPS module in the vehicle by com interface.
2, circuit identifying unit, for the distance between the line segment of the current longitude and latitude that calculates vehicle and Vehicle Driving Cycle circuit, and whether judging distance is less than or equal to the width of the line segment of vehicle line.
In the present embodiment, the circuit identifying unit links to each other with the line segment memory module; Store several line segments that form vehicle line in the line segment memory module.The circuit identifying unit also carries out corresponding distance calculating one by one at the front segment data that reads vehicle line from the line segment memory module of calculating distance.
3, warning device is used for during greater than the width of the line segment of vehicle line, sending warning in distance.
In the present embodiment, warning device comprises alerting signal generating unit and the loudspeaker that links to each other with the alerting signal generating unit and GPRS module.The alerting signal generating unit can carry out by loudspeaker the prompting of sound, and the prompting driver needs to travel according to given line when vehicle in front has been offset circuit.Loudspeaker can be special the outfit, also can share with the loudspeaker of vehicle.The GPRS module is used for to monitoring system alarming, by the GPRS module, can carry out the GPRS network warning or carry out the warning of SMS short message, use GPRS can be connected to monitor supervision platform, carry out the network alarming of monitor supervision platform, and the current line truck position information of vehicle is reported together; Also can use SMS to send the alarming short message breath to the mobile phone of appointment.
The principle of work of present embodiment is:
A) vehicle line is divided into several line segments, and N line segment of registration, the endpoint location of corresponding line segment and the information such as width of line segment are existed in the line segment memory module.In 2 modes of determining a line segment, carry out the segmentation of circuit, a circuit can have a plurality of line segments.
B) position detecting device utilizes the current longitude and latitude of the vehicle that position detecting device obtains, the circuit identifying unit reads the segment data of vehicle line from the line segment memory module, calculate the current longitude and latitude of vehicle and the distance of article one line segment, such as the length of this distance within this line width or equal this line width, then judge in the online road of vehicle in front, otherwise proceed the calculating of current point and next line segment distance, as all line segments calculate complete do not have yet less than line width apart from length, then judge outside the online road of vehicle in front.
Circular is as follows: the end points of supposing certain line segment is A, B, and current Vehicle Driving Cycle point is P, then the earth is regarded as a circle, and AB, PA, PB are fan-shaped arc length, calculate respectively the length of AB, PA and PB; Have three kinds of situations this moment, and the one, AB=PA+PB, P point judge in circuit on the AB line; The 2nd, AB, PA and PB are leg-of-mutton 3 limits, and the angle of AB and PA, PB is all less than 90 degree, then P is height corresponding on the leg-of-mutton AB of the calculating limit with the AB distance, utilize Heron's formula and triangle area formula, can calculate on the AB limit corresponding height, can judge relatively that according to this length and line width this point is whether in circuit; The 3rd, AB, PA and PB are leg-of-mutton 3 limits, and wherein arbitrary angle of AB and PA, PB greater than 90 the degree, then the distance of P and AB is a leg-of-mutton length of side, if the angle of AB and PA is greater than 90 degree, then the distance of P and AB is PA, otherwise is PB, judges with the second situation.
C) for preventing GPS drift, set enter continuously same line segment more than 5 seconds just identification enter this line segment, set equally continuous 5 seconds and go out this line segment, assert line segment and notify warning device.
Vehicle Driving Cycle stitch seam leans out line supervisory system of the present invention, simple in structure, easy to use, can use the longitude and latitude that from the GPS module, obtains and the circuit of presetting in advance, judge whether current driving route departs from given line; When searching the deviated line dataway operation, can filtering a large amount of unnecessary data, save with map on the circuit work of contrasting, and point and the time of can very fast finding departing from circuit; When vehicle generation circuit departs from, provide alert service, comprise the driver is carried out voice reminder and to monitoring system alarming.
The above is the preferred embodiments of the present invention only, is not limited to the present invention, and for a person skilled in the art, the present invention can have various modifications and variations.Within the spirit and principles in the present invention all, any modification of doing, be equal to replacement, improvement etc., all should be included within protection scope of the present invention.
