Embodiment
The present invention is described in further detail below in conjunction with accompanying drawing.
It is the intelligent management system that is used for big-and-middle-sized parking lot (Fig. 1) that main body constituted by inlet control module, parking stall measure module, parking stall statistics and bootstrap module, control of export module and host computer that the present invention is one.The microcontroller of inlet control module, parking stall measure module, parking stall statistics and bootstrap module, control of export module adopts 16 single-chip microcomputers, and its inside is integrated with the CAN controller; The parking stall measure module is made up of switching value detection chip UP1 and peripheral circuit thereof, can detect the situation that takies of 22 parking stalls.
The inlet control module is arranged in the Entrance place among the present invention, form by video camera, inlet road, hurdle machine and parking space information display screen, camera-scanning begins to scan car plate when having car to enter, read vehicle license plate information, when reading successfully, give an order and lift to inlet road, hurdle machine control railing, send the CAN message simultaneously, keep supplying a machine testing, vehicle enters the parking lot; Increase manual mode simultaneously in order to avoid the identification car plate is enabled when makeing mistakes.The parking space information display screen is used for showing in real time parking position information of park (Fig. 2).
The parking stall statistics realizes automatic guidance function with bootstrap module by the guide plate that control is distributed in each intersection, realizes the layering guiding by different intersections.The use information of each regional parking stall that the parking stall measure module of utilizing parking stall statistics and bootstrap module is detected is controlled the working condition of guide plate indication, intersection in the parking lot, when there is free parking stall in the zone that leads to a certain direction, the corresponding blinker that points in this regional guide plate is bright, show position, empty parking stall simultaneously, the user selects the parking area of oneself by the indication of guide plate.
The parking stall measure module is by areal distribution, and have or not car, the vehicle that are used for parking stall in the surveyed area enter the state that leaves with vehicle, and sends corresponding C AN message.All there are a sensor and a pilot lamp in each parking stall.When a certain parking stall was sky, pilot lamp was bright, showed this parking stall for empty, and the guide user is stopped; When sensing detection when having vehicle to sail the parking stall into, the parking stall measure module detects the status information of parking stall, and forms corresponding C AN message and send on the bus, pilot lamp goes out; When vehicle sailed out of the parking stall, the parking stall measure module detected the status information of parking stall, and formed corresponding C AN message and send on the bus, and pilot lamp is bright.The parking stall measure module is periodically gathered the status information on each parking stall in the region, and collection result is used with bootstrap module for host computer and parking stall statistics, and host computer carries out statistical management with this parking space information to the parking lot.
Host computer places Garage Administration, main realize management and monitors the whole running state monitoring of leading position and management system, timely alert notice managerial personnel processing when making a mistake.
The control of export module places the exit in parking lot, is mainly used in the library management that of vehicle.Vehicle sails the outlet fixed area into, video camera scans and reads license board information to vehicle, be transferred to the host computer statistics of charging, after subscriber payment finishes, host computer sends control command, the control of export module receives control signal driving outlet road, hurdle machine and lifts, and the user drives to roll away from the parking lot.
Parking stall bootstrap module among the present invention can be made up of switching value detection chip UP1 and peripheral circuit thereof.UP1 is the core parts of this circuit, and it can adopt MC33993 model or other similar chip (Fig. 3).UP1 comprises 8 road programmable switch amount detection port and 14 tunnel low-end switch detection port, and wherein 8 road programmable switch amount detection port are that low-end switch inserts by software setting, and the switching value detection chip is communicated by letter by the SPI communication interface with microcontroller.Described switching value detection chip UP1, it is X6, X7 that the low-end switch amount detects mouth, the relevant pin of SPI communication is X2, X5, X3 and X4, the chip grounding pin is X1, chip+5V power pins is X8, chip+24V level pin is X11, and analog quantity multichannel output pin is X10, and the look-at-me output pin is X10;
The annexation of each pin of UP1 is: low-end switch signal SL0, SL1 link to each other with X6, X7 pin respectively, filter capacitor C3, C4 be attempted by respectively X6, X7 pin and+5V power supply ground GND between; UP1 communicates by letter by the SPI communication interface with microcontroller, and relevant pin is X2, X3, X4 and X5; The X10 pin of UP1 links to each other with the analog quantity input interface AN03 of microcontroller, and by capacitor C 5 ground connection; The X10 pin links to each other with micro controller I/O mouth PA6; Filter capacitor C6 is connected between power positive end VPWR and the power supply negative terminal VPWR-.
The vehicle parking flow process is among the present invention: distinguish when vehicle sails the fixing shooting of inlet into, video camera detects vehicle and reads license board information, sends CAN message driving road, hurdle machine and lifts railing; The user utilizes the parking stall automated induction systems in parking lot to search out the parking stall, finishes parking work; When vehicle leaves the parking lot, the fixing shooting district of at first stopping, video camera is discerned automatically, the keeper calculates parking fee according to license board information and toll rate then, treat that the user pays the fees and confirms after, railing lifts, vehicle leaves the parking lot (see figure 3).
The content that is not described in detail in this instructions belongs to this area professional and technical personnel's known prior art.
