Description

Radar system for school bus

Technical field

The utility model particularly relates to a kind of radar system for being suitble to be installed in school bus about a kind of Radar Technology field System.

Background technique

The school bus used in student goes to school, classes are over is generally picked, since school bus car body volume is longer and larger, and working as will stop Pull in it is middle traveling or shifting vehicle when, often can because of school bus car body volume relationship and block driver and be intended to advance or move the sight of vehicle (i.e. so-called visual dead angle), and driver can not prevent in time and reacts unexpected generation.

Therefore, it is improved on radar system and its component as how being installed on school bus, and then is effectively improved Aforementioned problem, actually the purpose of this utility model.

Specific embodiment

It please refers to Fig.1 to Fig.3, is suitble to be installed in a school bus for one kind disclosed by the utility model first preferred embodiment 10 radar system 20, and the radar system 20 includes:

One host 30 is installed among the school bus 10.

Two radars 40, protrusion setting is located at the same long side of one of the school bus 10 car door 11 respectively, it is preferable that this two If a radar 40 is using ground as benchmark face, it is respectively positioned on the identical height of the same long side of 10 car body of school bus；And two thunders It is electrically connected up to 40 in the host 30, and any radar 40 has the monitoring source 41 of a plane one-way.However it is single Monitoring source 41 is relatively also easy to produce detecting blind sector, and so-called detecting blind sector is exactly the range that each radar installations can not detect, Therefore, if barrier enters detecting blind sector, because radar detecting is less than so be unable to reach warning function, if improvement is detectd The problem of surveying blind sector can be in a manner of increasing monitoring source 41, for example, by using the monitoring of multiple monitoring sources or array type There is dead detecting angle in source, the detection zone for improving known radar device.

And it is noted that using the long side of 10 car body of school bus as benchmark face, and any radar 40 and the school bus The long side of 10 car bodies forms a tilt angle (schema is not marked), and makes the vacation in the monitoring source 41 perpendicular to any radar 40 Idea line L1, L2 extends towards the direction of the long side far from the school bus 10, and then intersects and form an imaginary angle theta₁.In addition, Any radar 40 and ground also form a pitching angle theta₂。

And radar system 20 disclosed in the utility model first preferred embodiment, the effect of being reached be In:

One has effects that warn the monitoring for being convenient for judgement with sharp driver respectively.Referring again to Fig. 1, i.e., when the host 30 when switching to a monitoring pattern (not shown), generate a radar start signal and be transmitted separately to two radars 40 to Start two radars 40, at this point, signal caused by the monitoring source 41 of two radars 40 is made to can be used to monitor whether Personnel or foreign object are covered or are covered, and then respectively corresponding alarm signal is back to the host 30 again, and driver is allowed to be able to To be convenient for judgement personnel or foreign object currently it is by alarm signal caused by the host 30 (such as: buzzer or warning cresset) The no periphery positioned at the school bus 10, and then driver is reminded to pay attention to the generation simultaneously effectively to prevent an accident.

Secondly, tool intersection kenel solid space monitoring network, the traveling to the emergent stopping school bus.Described in brought forward, Since two radars 40 are the relationship being obliquely installed compared to the long side of 10 car body of school bus, so that two radars 40 These imaginary normal L1, the L2 in monitoring source 41 extend towards the direction of the long side far from the school bus 10 and intersect and form this Imaginary angle theta₁, and the imagination angle theta₁Angle between 30 degree to 150 degree, and be based on the imagination angle theta₁Covered Region deviding is one first imaginary area；In addition, any radar 40 and ground are formed by the pitching angle referring again to Fig. 3 θ₂Angle between 70 degree to 110 degree, and be based on the pitching angle theta₂The region deviding covered is one second imaginary area. The first imaginary area and second imaginary area's institute's intersection for being defined as a result, based on two radars 40 and form a solid space Monitoring network.

Described in brought forward, and supervised when thering is personnel or foreign object to be formed by the solid space by the monitoring source 41 of two radars 40 When survey grid network is covered or covered, corresponding urgency signal (not shown) will be generated and be back to the host 30, and the host 30 generated according to the urgency signal urgent alarm signal (such as: buzzer or warning cresset)；Then, driver is according to the master Urgent alarm signal caused by machine 30 and stop moving the school bus 10 immediately, until personnel or foreign object are supervised far from the solid space After survey grid network, the school bus 10 can be just continued to move to, thus the serious unexpected generation of prevention.And it is noted that this two These imaginations normal L1, the L2 in the monitoring source 41 of a radar 40 intersect and form the preferred imagination angle theta₁Angle is between 50 It spends between 130 degree, and any radar 40 and ground are formed by the pitching angle theta₂Optimized angle between 80 degree to 100 Between degree；It is highly preferred that its angle of the optimum range of scanning signal produced by the monitoring source 41 of any radar 40 is 90 degree.

Referring to Fig. 4, being suitble to be installed in a school bus 10A for another kind disclosed by the second preferred embodiment of the utility model Radar system 20A, and radar system 20A primary structure is same as aforementioned first preferred embodiment substantially, and it includes have installing A host 30A and four radar 40A in the school bus 10, and the difference is that:

These radars 40A is electrically connected in host 30A, and protrusion setting is located at school bus 10A two sides respectively The intersection on side；And any radar 40A has the monitoring source 41A of a curved surface polytropism, implies that the monitoring of any radar 40A The field angle of scanning signal caused by the 41A of source is between 5 degree to 355 degree.

Referring to Fig. 5, being that another is suitble to be installed in a school bus 10B disclosed by the utility model third preferred embodiment Radar system 20B, and radar system 20B primary structure is same as aforementioned first preferred embodiment substantially, and it includes have installing A host 30B and six radar 40B in school bus 10B, and the difference is that:

These radars 40B is electrically connected in host 30B；Setting is protruded respectively in two radar 40B systems therein Positioned at the same long side of school bus 10B, another two radar 40B protrude the front side edge that setting is located at school bus 10B respectively, remain Back side edge of the setting relative to the front side edge of school bus 10B is protruded respectively in remaining two radar 40B systems.

Finally, must illustrate again, all clearly to know in those skilled in the art, these are described in detail and this reality With novel cited embodiment, the effect for only being suitable for illustrating structure, method, process of the utility model etc. and its being reached, Rather than to limit the utility model application protection scope scope, other equivalent elements, component, object, structure, device, The substitution or variation of method or process, the application protection scope that also should be the utility model are covered.
