How does KEYTOP parking system works:
ultrasonic detector is installed right above each parking space to collect real-time parking status.Meanwhile,ultrasonic detector will send commands to LED indictor to control its color change,turn red when parking space is occupied,turn green when vacant.ZCU will scan the detectors which is under its control to collect data,then send to CCU.CCU will send commands to LED display after data processing to show the vacant parking space quantity.
