Description of drawings
Fig. 1 is hardware connection diagram of the present utility model.
Below in conjunction with drawings and Examples particular content of the present utility model is done explanation in further detail.
Embodiment
Below provide specific embodiment of the utility model, need to prove that the utility model is not limited to following specific embodiment, all equivalents of doing on present techniques scheme basis all fall into protection domain of the present utility model.
Defer to technique scheme, as shown in Figure 1, a kind of parking garage pilot device for parking, comprise single-chip microcomputer, PC and microcontroller, this device also comprises infrared reflection photoelectric tube group, ultrasonic sensor, outdoor display screen, indoor display screen and guiding lamp, wherein, infrared reflection photoelectric tube group links to each other with single-chip microcomputer by A/D converter, ultrasonic sensor links to each other with microcontroller, single-chip microcomputer links to each other with PC respectively with microcontroller, also be connected with indoor display screen and guiding lamp on the microcontroller, also be connected with outdoor display screen on the PC.
Infrared reflection photoelectric tube group is two infrared reflection photoelectric tubes, be designated as photoelectric tube 1 and photoelectric tube 2, be installed in each place, gateway, parking lot, when passing through photoelectric tube 2 again through photoelectric tube 1 in the ban, expression has vehicle to enter, after the infrared reflection photoelectric tube passed to single-chip microcomputer with signal, the interrupt service routine of single-chip microcomputer can call and subtract counting, namely allowed the available parking places number that shows subtract 1.Equally, when car comes out from the parking lot, can pass through photoelectric tube 1 again by photoelectric tube 2 earlier, the interrupt service routine of single-chip microcomputer can call and add counting, and namely available parking space number adds 1.
Ultrasonic sensor adopts the SRF05 ultrasonic sensor, installs one above each parking stall, is used on the unloading lot detection whether vehicle parking being arranged.Ultrasonic sensor utilizes the time difference after ultrasound wave emission, testee reflection, echo receive to measure tested distance.When no car, the time difference is long; When car was arranged, the time difference was short.Judge with this whether car is arranged.
Microcontroller adopts Samsung based on the ARM920T microprocessor of ARM company, but its highest travelling speed can reach 203MHz.This microprocessor has: independently 16KB instruction Cache and 16KB Data Cache, and MMU supports the lcd controller of TFT, nand flash memory controller, 3 road UART, 4 road DMA, the Timer of 4 road band PWM, I/O mouth, RTC, 8 tunnel 10 ADC, Touch Screen interface, IIC-BUS interface, the IIS-BUS interface, 2 usb hosts, 1 USB device, SD main frame and MMC interface, 2 road SPI.It has abundant I/O interface, can satisfy needs of the present utility model fully.
Single-chip microcomputer adopts the STC89C52 single-chip microcomputer.STC89C52 has comprised 8 bit CPUs, sheet internal oscillator, 8K bytes Flash, 512 byte RAM, 2 16 bit timing devices, counter, interrupt structure, I/O interface etc.
PC adopts the industrial computer of present market main flow, i.e. the enhancement mode personal computer of Jia Guing, stable performance.
Outdoor display screen and indoor display screen all adopt dot matrix LED display screen.Indoor display screen is installed in fork important in the parking lot, shows arrow points and the last parking stall of each subregion number, and outdoor display screen is installed in the Entrance place, is used for showing total parking stall situation in the parking lot.
Guiding lamp adopts high brightness, and the red LED lamp of low-power consumption and green LED lamp are installed one group of red LED lamp and green LED lamp above each parking stall, be respectively applied to indicate the parking stall to take and idle state.
If the gateway in the parking lot of same position, then only needs to install the photoelectric tube group of two infrared reflections, namely can carry out the counting of parking stall number.If having is the parking lot that outlet and entrance separate, an infrared reflection photoelectric tube group then is installed in the porch, an infrared reflection photoelectric tube group also is installed in the exit, when car enters from entrance, then the available parking places number subtracts 1, when car was gone out from outlet, then available parking stall number subtracted 1.By the RS232 interface of single-chip microcomputer, the available parking stall counting number information that obtains is delivered in the PC by the RS232 communication simultaneously, handled.
When vehicle enters into inside, parking lot, it enters the parking stall and with after stopping, ultrasonic sensor is given microprocessor with the ultrasonic signal that reflects by the RS485 bus and is handled, computing time is poor, to judge whether the parking stall is occupied, all parking space information after will handling then are passed to PC by the RS232 bus, pass to indoor display screen by the RS485 bus.Whether microprocessor can occupied according to each parking stall, and the parking stall guiding lamp is controlled, if namely this parking stall is occupied, then red parking stall guiding lamp is bright, if this parking stall is unoccupied, then green parking stall guiding lamp is bright.
After single-chip microcomputer imports the detected parking stall of infrared reflection photoelectric tube group number into PC, be not this parking stall sum information directly to be delivered to outdoor display screen show, but the hysteresis parking space information that will obtain by ultrasonic sensor therewith the parking stall information of counting carry out feedback modifiers, to improve the accuracy of available parking stall number.For example, when whole parking lot only remains last parking stall, if the instantaneity that does not have the infrared reflection photoelectric tube that vehicle number is detected, may many cars that sail into, have only one can park, other can only sail out of or disorderly stop.Infrared reflection photoelectric tube group and ultrasonic sensor are used, and have remedied the deficiency of the parking stall measure system that only uses ultrasonic detector.
