Car park guidance system

CAN connects multi-color ultrasound sensors

Siemens (Germany) has developed the Sipark SSD System. The hierarchical system uses Ethernet as backbone and CAN networks to link sensors, displays, and indicators.

THE SIPARK SSD CAR PARK GUIDANCE SYSTEM is suitable for solutions with just 10 parking spaces, but can also be used for up to 15 000 cars. The PC-controlled system uses an Ethernet backbone to connect different CAN sub-networks. The CAN networks link multi-color ultrasound sensors. Up to 240 sensors can be controlled in one network. They are installed in the ceiling above each parking space. The sensors provide distinctive color-coding for up to six different types of parking spaces. Other devices communicating via CAN include the numerical displays and status indicators as well as car park display and zone guidance signs.

The overhead ultrasound sensors allow detecting the current occupation status. This means the operator always has a complete overview of how many and which parking spaces are occupied and which are free. In addition, it is possible to assign a special-zone status to certain parking spaces and reserve them for a specific group of users (e.g. handicapped drivers or VIPs) – permanently or for a certain period of time only. The dynamic direction signs, also controlled via CAN networks, lead each group of users directly to the zone reserved for them.

The park guidance system is installed for example at the airport in Munich (Germany) with over 15 000 parking spaces. Worldwide, far more than 100 000 parking spaces have been equipped with this system. Other references include a 27 parking spaces application in Lausanne (Switzerland) for the Migros supermarket and car parking with 853 spaces at the Playmobil Fun Park in Zirndorf (Germany). There are also installations in Athens (736 parking spaces), Bratislava (224), Doha in Quatar (2932), and Belgrade (1236).
