1 Keytop Parking Guidance System (PGS) As one of the best parking guidance system suppliers, Xiamen Keytop has the most successful cases which are from different parts of the world than other China suppliers. The main function our parking guidance system (PGS) has is that helps the driver find free parking space on different layers and sectors quickly. Using LED display and LED indicator to show the real time parking information (free/occupied parking space) to the vehicle owners. Moreover, the owners or operators can monitor the real time parking information as well as collect and analyze statistic data about utilization of each car park space. What are the benefits of Parking Guidance System? PGS have been proven to cut the cutomer's time to park in half and result in a 3 5% rise in visits. Simply put, the easier it is for customers to visit, the more customers will want to return again and again. Travellers: Reduced time looking for parking, and reduced frustration.

2 Venue Operators: Increase in patronage, and customer satisfaction. Parking Operators: Increased space occupancy, and increased revenue. Environmental: Reduced air pollution, reduced congestion, reduced illegal parking. PGS Key Components: CCU: Central Control System ZCU: Zone Control System UD: Ultrasonic Detector LED Indicator: Red/Green Led Indicator LED screen: Outdoor/Indoor LED screen PGS wiring diagram How PGS Works: Firstly, UD takes use of ultrasonic wave to detect the car space to see if it

is occupied by vehicles and transfer relative command to LED Indicator which will turn from green to RED when occupied, or it will keep GREEN; meanwhile, the UD transmit its status message to ZCU

CCU 1) Specification: work temperature: 20~+80 rate voltage: AC 110~220V frequency: 50~60HZ communication: 2 RS 232 serial port(rs 232 NODE RS 232 PC) baud: RS 232 NODE:9600bps;RS 232 PC:57600bps

3 is occupied by vehicles and transfer relative command to LED Indicator which will turn from green to RED when occupied, or it will keep GREEN; meanwhile, the UD transmit its status message to ZCU immediately, and ZCU will collect and forward the information to CCU; CCU processes these data and sends the relevant command to ZCU and LED panel. 1. CCU 1) Specification: work temperature: 20~+80 rate voltage: AC 110~220V frequency: 50~60HZ communication: 2 RS 232 serial port(rs 232 NODE RS 232 PC) baud: RS 232 NODE:9600bps;RS 232 PC:57600bps distance: 1000m 2) Main function: 1. CCU main function is to inquire about the relevant ZCU data via RS232 NODE by turns and process these data; then send these processed data to PC or other relevant equipments; besides it updates the LED display s data via RS232 NODE. 2. One CCU can support 60 ZCU in max.. 2. ZCU

4 1)Specification: Size: 30*24.5*6(CM) Work temperature: Rate Voltage: DC 24V Rate current: 70mA Communication: RS 485 serial port (sensor/sensor/ccu) Baud: RS 485 B: 4800bps, RS 485 C: 9600bps Distance: 1000M 2)Main function: 1. It is to inquire about the relevant sensors status via RS485 B by turns, and forward the data to CCU by RS485 C.Meanwhile, the ZCU forwards the command of CCU to LED screen via RS485 B. 2. The RS485 B data bus can support 60 UD in max., whose addresses must not be set repeatedly.

5m Max error: 0.1m Detecting area (3.5m): 0.4sq.m Communication: RS 485 baud velocity: 4800bps, N,8,1 Available distance: 1000m 2) Main Functions: 1.

7 1) Specification: Size: dia. 100*23(mm) Weight: 113g Principle: Ultrasonic Work temperature: 20~+80 Current rating: 13mA+17mA(LED indicator) Voltage rating: DC 24V Detecting arrange 0.1~3.5m Max error: 0.1m Detecting area (3.5m): 0.4sq.m Communication: RS 485 baud velocity: 4800bps, N,8,1 Available distance: 1000m 2) Main Functions: 1. UD(ultrasonic detector) as one of the main part of parking guidance system makes use of ultrasonic detecting the parking space to get message and transfer to ZCU or other equipments by RS One parking space needs one UD which is installed in the middle of the car park space. 4. LED indicator VACANT OCCUPIED

it will turn from green to red when it occupied, or it

8 1)Main Functions and Features: 1. Install LED indicator in the front of car park space for the convenience of driver s observation. 2. Show the parking information to the driver by its color, it will turn from green to red when it occupied, or it will keep green 3. One park space needs one LED indicator. 5. LED screen 1)LED indoor screen

rate voltage: AC 110~220V frequency: 50~60HZ communication: RS 485 baud: 4800bps distance: 1000m 2)Main Functions and Features: Three digits are to show the available lots number and the arrow is to

10 rate voltage: AC 110~220V frequency: 50~60HZ communication: RS 485 baud: 4800bps distance: 1000m 2)Main Functions and Features: Three digits are to show the available lots number and the arrow is to show the direction. The led indoor screen will be installed at the crossings of car park. The outdoor led screen will be installed at the entrance of car park or other outside place. 6. Software Remark: The red one means occupied, the green one means vacant.

11 Remark: The left is led screen list and the right is the detector list. 1). Flow Statistic means total car s quantity in your appointed time Eg: From 12:00 to 13:00, there are THREE cars driving into the Car Park in

12 this hour, so it means Flow Statistic=3 2). Use Ratio = [sum (each space s use time)]/ (appointed time*total space in the Car Park) Eg: there are 5 spaces in the Car Park, today the parking spaces are only used between12:00 13:00 Space1 used time: 0.5 hour, Space2 used time: 0 hour Space3 used time: 0.6 hour, Space4 used time: 1 hour, Space5 used time: 0 hour So the Use Ratio between 12:00 13:00=( )/(1hour*5spaces)=2.1/5=42% And today s Use Ratio= ( )/(24*5spaces)=1.75% Green considered as used (occupied), Red means not used (vacant) Eg: suppose the Car Park information between12:00 13:00 is as below: Time vacant space occupied space Total space

12:01 4 1 5 12:30 3 2 5 12:33 2 3 5 12:45 5 0 5 So the Use
