Tips to design your own Parking Guidance System project

Parking Guidance Systems (PGS) have been proven to cut the customer's time-to-park in half and results in a 3‐5% rise in visits. The easier it is for customers to visit, the more frequently customers will return.

More and more car park operators realize the importance of installing a PGS in their car park, so when a client asks your advice, how do you design a parking guidance solution that most suits their requirements? Here are some tips that can help. 

Suppose the project has 1200 parking spaces, 3 levels.

First, we need to know the PGS diagram:

We know that a parking guidance system mainly consists of:

  • CCU: Central Control Unit (With Software)
  • ZCU: Zone Control Unit
  • UD: Forward Mounting Ultrasonic Detector
  • LED screen: Outdoor/Indoor LED screen

The next step is to decide how many of the above apparatus are required for this project.

CCU: The main function of CCU is to establish the relevant ZCU data by turns, it processes this data and then sends the processed data to the server or other relevant equipment. CCU has built in management software, usually, a project needs one CCU.

ZCU: The main function of the ZCU is to establish the relevant sensors’ status via RS485-B by turns, and forwards the data (refer to Connection explanation) to CCU by RS485. Meanwhile, the ZCU forwards the command of CCU to LED screen via RS485-B. Theoretically, one ZCU can support 60 sensors, there are 1,200 parking space in this project, so 20 ZCU's will be required.

UD (Utrasonic Detector): These are installed at the front of each parking space detecting the occupancy in order to relay this message to the ZCU. The built-in led indicator will change from green to red when the parking space is occupied. One parking space needs one UD, so 1200 sensors are required.

LED indoor display: LED indoor display will be installed at the crossings or the entrance to display real time parking information to the drivers.

The arrow will show the direction to the drivers and the three digits will tell the drivers how many parking spaces are available. 

A professional engineer will design the indoor led display quantity accordingly to the car park layout. There is a simple way to work out an estimated led display quantity:

Parking Space Qty ÷ 40= indoor display QTY.

So in this project approximately 1200÷40=30 pieces of indoor displays are required.

LED outdoor display: The LED outdoor display will be installed at the outdoor entrance to show information about the whole car park to the drivers. There is one entrance in this project, so one outdoor display (with 3 led panels) is required.
