Further, described fixed speed signal producer is provided with independent power supply.
Further, described independent power supply is a solar cell.
Further, described system also comprises the phonetic warning unit, and the alarm signal mouth of itself and described Vehicle Controller links.
Further, described restricting signal producer is arranged on school gate, school bus station, doorway, sub-district.
Further, described school bus is a pure electric vehicle.
The utlity model has the technical characterstic of identification intelligentization, under the prerequisite that improves school bus safety, make school bus automation and intelligent level be further enhanced, can not make vehicle ' the hypervelocity phenomenon occur because of the carelessness of chaufeur, can significantly reduce even stop the school bus traffic accident that, overspeed of vehicle bad because of light etc. is former thereby lead to.
Description of drawings
Fig. 1 is the utility model structured flowchart.
The specific embodiment
Development along with the school bus technology; school bus is progressively to high safety; high environmental protection; high automation; high monitoring property direction develops; school bus progressively be improved to pure electric vehicle; because battery-driven car adopts the mode of electronic circuit; be easy to automatic guidance; it is simple to have operating mode; monitor mode is simple; system integration degree advantages of higher; school bus is a pure electric vehicle in the present embodiment; but the protection domain of the utility model claim is not restricted to the scope that present embodiment is narrated, and the school bus speed of a motor vehicle autonomous cruise speed system that the utility model has the light illuminance transducer can be applicable to existing fuel oil vehicle; the combustion gas vehicle; the school bus of various ways such as electronic vehicle.
As shown in Figure 1, a kind of school bus speed of a motor vehicle autonomous cruise speed system that has the light illuminance transducer of the utility model, school bus is a pure electric vehicle, and the school bus speed of a motor vehicle autonomous cruise speed system that has the light illuminance transducer comprises school bus central controller, Vehicle Controller, restricting signal producer, phonetic warning unit and light illuminance transducer.Wherein:
The school bus central controller is used to receive the speed of a motor vehicle control signal that Vehicle Controller sends, the moving velocity of control school bus.The signal input part of school bus central controller and the signal output part of Vehicle Controller link, receive speed of a motor vehicle control signal after, the feed circuit of school bus central controller direct control school bus, depowering output, road speed slows down.
Vehicle Controller is arranged on the school bus, and it is the data processing center of total system, is provided with little process chip in it, and Vehicle Controller comprises signal receiving unit, control unit.
Signal receiving unit, the signal input part of its signal output part and control unit links, and is used to receive the restricting signal that the restricting signal producer is sent.
Control unit, the signal receiving end of its signal output part and school bus central controller links, be used to receive and the restricting signal imported of processing signals receiving element, restricting signal be converted into speed of a motor vehicle control signal, and speed of a motor vehicle control signal is transferred to the school bus central controller.
The restricting signal producer is arranged on the place that needs speed limit in the school bus running route, as is arranged on positions such as school gate, school bus station, doorway, sub-district, the mode by wireless signal to its be provided with the place around send restricting signal.
The phonetic warning unit, be arranged in the operator's compartment on the school bus, the alarm signal mouth of its signal input part and Vehicle Controller links, be specially: the alarm signal mouth of its signal input part and control unit links, after control unit monitors restricting signal, to phonetic warning unit output phonetic warning signal, the phonetic warning unit sends the caution voice to chaufeur, slows down, takes in a reef with alerting drivers.Simultaneously, the signal input part of phonetic warning unit also links with the alarm signal mouth of school bus central controller, is used to play the alarm signal that the school bus central controller is sent.
The light illuminance transducer, the signal receiving end of its signal output part and school bus central controller links, the light illuminance transducer is used for monitoring in real time the outer light intensity of school bus, and pilot signal is transferred to the school bus central controller, after the school bus central controller receives speed of a motor vehicle control signal, by analysis, the feed circuit of direct control school bus, the output of adjusting power is with the control road speed.When car UV light abundance, the school bus central controller will can not controlled the speed of a motor vehicle because of the reason of light; When the car UV light is not enough, after the real-time pilot signal of light illuminance transducer passes to the school bus central controller, through computing, the school bus central controller will draw and the present corresponding safety traffic speed of Illumination intensity, and then the school bus central controller can not surpass this moving velocity will control school bus and travel the time, to reach the effect of safety control.Meanwhile, the school bus central controller will be carried alerting signal to the phonetic warning unit, and prompting chaufeur car UV light is darker, slows down moving velocity, takes care.
The restricting signal producer adopts independent power supply power supply (not shown), and with reliability and the continuation that guarantees its work, in the present embodiment, this independent power supply is a solar cell, and it comprises corresponding solar cell plate and storage battery.
During work, school bus carrying student on fixed course with safety, speed is travelled efficiently, when school bus approaches school gate, the school bus station, during near positions such as doorway, sub-district, as these positions 500 in the time, signal receiving unit has received the restricting signal that the restricting signal producer sends, signal receiving unit imports this restricting signal immediately to control unit into, control unit is converted into speed of a motor vehicle control signal with restricting signal, and speed of a motor vehicle control signal is transferred to the school bus central controller, the feed circuit of school bus central controller direct control school bus, depowering output, slowly reduce road speed, until arriving school gate, the school bus station, speed during positions such as doorway, sub-district should be reduced to below 20 kilometers/hour.When the light illuminance transducer detected car UV light deficiency, pilot signal was transferred to the school bus central controller, thereby the control school bus travels with corresponding safety speed.
The pilot signal of light illuminance transducer also can be used for the comprehensive adjustment to school bus Lighting Systems such as the outer Lighting System of automobile, intraoral illumination system, gauge panel Lighting Systems, change or carry out car tunnel etc. at weather, the light illuminance transducer also can be used for monitoring timely, and by the school bus central controller timely head lamp is opened automatically, with the school bus room light open, the bias light brightness of adjusting apparatus dial plate etc., to reduce the time that steerman is handled, increase travel safety.
