Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.
A safety protection device for electric bicycle, its structural diagram is shown in figure 1, including fixed distance infrared sensor, camera, switch detection module, controller and alarm. The fixed-distance infrared sensor is arranged on the periphery of the electric bicycle and used for detecting objects around the electric bicycle; the camera sets up in electric bicycle's handlebar the place ahead for gather road both sides information and traffic signal lamp information, switch detection module is used for detecting electric bicycle on-off state, and the controller is used for handling the signal of gathering, and the alarm is used for sending out the police dispatch newspaper. The output ends of the fixed-distance infrared sensor, the camera and the switch detection module are respectively connected with the input end of the controller, and the output end of the controller is respectively connected with the controlled end of the speed controller on the electric bicycle and the input end of the alarm.
The fixed distance infrared sensors are arranged on the periphery of the electric bicycle and are used for detecting whether objects are in the fixed distance around the electric bicycle. When the electric bicycle is in the driving process, and the distance between the surrounding objects and the electric bicycle is smaller than the set distance of the fixed distance sensor, the fixed distance infrared sensor sends a control signal to the controller, the controller sends a control instruction to the alarm, and the alarm gives an alarm to prompt a driver to drive carefully. The utility model discloses the model of the fixed distance infrared sensor who uses in is VL6180XV0 NR.
The camera sets up the place ahead at electric bicycle handlebar for gather road both sides information and crossing traffic signal lamp condition, the information transmission of collection gives the controller, the information that the controller gathered the camera is compared with the information of storage, when electric bicycle traveles and gets into the motorway or makes a dash across the red light, send the warning through the alarm, remind the navigating mate to get into the motorway or made a dash across the red light, need in time park, guarantee safe driving. The model of the camera used in the utility model is AHD-ST-01.
The switch detection module comprises a gravity sensor and a gyroscope. The output ends of the gravity sensor and the gyroscope are respectively connected with the input end of the controller. The gravity sensor is arranged below the seat and used for detecting whether a person sits on the seat, and the gyroscopes are respectively arranged at the front and the rear wheel hubs of the electric bicycle and used for detecting the postures of the front and the rear wheel hubs. Switch detection module when two states above, still can detect electric bicycle's switch simultaneously and open, when detecting that the seat has sat down, electric bicycle's switch has opened and electric bicycle's the unanimous three condition in the gesture of wheel hub is satisfied simultaneously around, the controller sends control command for speed controller, and at this moment, rotation speed controller, electric motor car just can start, can effectively prevent electric bicycle's mistake and start, has ensured the personnel's of riding safety. The utility model discloses the model of gravity sensor who uses in is WSH-5, and the model of the gyroscope of use is ADIS16405, and the model that the controller adopted is AT89S52 singlechip, and its circuit diagram is shown in FIG. 2.
The utility model discloses well distance infrared sensor, the camera, gravity sensor and gyroscope are the finished product of purchasing on the market, wherein distance infrared sensor's output is connected in the P10 end of singlechip, the P11 end at the singlechip is connected to the output of camera, gravity sensor's output is connected in the P16 end of singlechip, the P17 end at the singlechip is connected to the output of gyroscope, the controlled end of speed controller on electric bicycle is connected to the P20 end of singlechip. And the singlechip receives and processes signals of the fixed-distance infrared sensor, the camera, the gravity sensor and the gyroscope, and sends a control instruction to the speed controller according to the acquired signals.
The utility model discloses when electric bicycle starts, navigating mate sits on the seat, opens the switch, after two wheel hub's state unanimity around detecting, just can start electric bicycle, rotation rate controller this moment, electric bicycle moves ahead, at the in-process of traveling, state around fixed distance infrared sensor and the camera real-time detection electric motor car to can give navigating mate with dangerous state suggestion, remind navigating mate to drive carefully, guarantee driving safety.
