1) Description 
  Parking  guidance system is a indicating system of guiding the driver to the parking  places successfully.Generally,it’s an intelligent parking guidance system in  parking lot that guide the drivers to park into the empty spaces, use  intelligent control system to detect the parking spaces,show the available  parking spaces through display screens;the driver can park easily through the  information.
  2)System structure
  1.  Ultrasonic detection system:
  Install the ultrasonic probe in the upper right of  the car,and set the detecting distance and address.The ultrasonic probe  detecting distance can be set from1.5-3.0,total 4levels(the specific distance  can be set according to client needs),data transmission mode use RS485 bus,a  bus is recommend to connect max up to 25 ultrasonic detectors. 
  2.Data acquisition system
  Four  ultrasonic detection system connect to one parking spaces controller,each  parking spaces controller is connected via CAN bus to form a regional data  acquisition system,and send the regional parking data to the data processing  center(PC or parking spaces display).Parking spaces controller address can be  set to any address of 0-63,prohibit repeat setting. Four ultrasonic detection  system can be divided into four regional model, convenient for user to install  flexibly according to the actual working environment.
  3.Parking spaces output display system 
  Install  a parking spaces display to show the parking empty information at each regional  or each main road,and according to each regional area parking spaces  number,with the flashing arrow,intelligently guide the driver to the area with  more packing spaces to park,to promote the   parking places reasonable distribution of parking lot.
  3)System function
  
      - Guide parking easily,fast parking,save time,reduce  fuel consumption
- Statistic parking lot utilization,rational  allocation of resources,increase the parking lot operational efficiency.
- Enhance the parking management level,improve the  image of property management.
- Reduce the human resources investment cost of  property management.
 
    
    Ultrasonic parking detector UD32-R 
     
     1)Introduction
  The  parking detector uses the principle of ultrasonic distance measurement, use the   ultrasonic transmitter, the object  reflection, after receiving the echo time difference to measure the parking  garage current situation. RS485 communication bus design, anti-interference  ability, an RS485 bus can connect up to 25 parking spaces detectors. Industrial  design can be adapted to a variety of harsh environments, and it plays a  guiding role as safe parking of city vehicles.
