Embodiment
As shown in the figure, a kind of intelligent parking system based on the sectional type pid control algorithm, described intelligent parking system comprises central controller, infrared ray sensor, state sensor and the wireless output module that is arranged in the garage, described central controller is connected with infrared ray sensor, state sensor and the output module of being connected respectively, and described state sensor is arranged on the parking stall; Described intelligent parking system also comprises the photoelectric sensor that is arranged on the vehicle body, wireless receiving module, singlechip controller and PID regulator, described singlechip controller respectively with the PID regulator, photoelectric sensor is connected with wireless receiving module, described singlechip controller adopts auspicious Sa R8C38A processor, described garage road-center is provided with an illuminated centerline that is made of LED, be provided with the stop sign line on the described parking stall, reversing markings and state sensor, described stop sign line is an isolychn that is made of LED, and described photoelectric sensor is arranged on the dolly bottom.
Road center in the garage in the utility model adds that road center line that white led lamps makes is as the tracking line of dolly navigation.On each parking stall, be provided with stop sign line and state sensor, the stop sign line is used for the control dolly and stops in the position of appointment, state sensor is used for the sign parking stall and whether is in idle condition and its status data real-time update is reached CCC, and then guides dolly to go to the Parking Stall of idle condition.Other carry photoelectric sensor below dolly, it is in one line that sensor becomes, the luminescent road center line that forms for detection of the LED on ground.The route safety traffic that dolly is guided according to central controller.The tracking of dolly travels and adopts the sectional type pid control algorithm, and under the guide of central control unit, the dolly tracking advances like this, finishes the safe and intelligent parking service.
To establish an infrared ray sensor in each fork on the road.Described infrared ray sensor is the diffuse reflectance infrared sensor, wireless output module is controlled by central processing unit, just can be by the diffuse reflectance infrared sensor senses when dolly is passed by the intersection, and little truck position reached central processing unit, central processing unit can be calculated this intersection according to parking space state, and whether needs are turned, and by wireless receiving module steering order being reached dolly, dolly judges whether and will turn according to instruction again.
The dolly line walking then relies on the singlechip controller on the dolly, and the singlechip controller of native system adopts auspicious Sa R8C38A processor.Roadside information has vehicle-mounted photoelectric sensor collection, directly reaches single-chip microcomputer, and through the processing output control signal of PID regulator, the direction of control dolly is travelled dolly all the time along center line.When going to the fork in the road, the instruction that sensor is sent according to central processing unit judges whether to turn in this fork in the road.
On each parking stall, all be provided with stop sign line and reversing markings, these two markings are all on the parking stall, but because its position on the parking stall is different, the result who therefore detects will be different, provide different instructions according to different as a result dollies again.
The utility model calls different PID according to different road conditions, such as the PID that then can call special disposal right angle bend when running into the right angle detour, then can call different PID according to the radian size of different bends again when running into bend.Just can guarantee so on any road conditions, can both guarantee that dolly can draw correct enforcement order.Sectional type PID improves Security of the system, reliability.
