Automated Parking Systems See how the Internet of Things has made
this industrial infrastructure application a reality
Modern automated parking complexes commonly include integrated electromechanical transmission control, security control, detection systems and automated placement. The systems can fully support vehicle measurement, image analysis, electronic payment scanning, and automatic retrieval.
In an automated parking complex, drivers need only park at an entry pallet or port. Images of the car are captured and transmitted to a controller where dimensions of the car are read and the license plate recorded. Meanwhile, the driver pays by card and the system provides authorization, possibly via voice recognition. Once sensors have verified the entry pallet or cabin is empty of occupants, the process of automatic moving and parking will be initiated. The car will be moved by an elevator or a carousel system up to the storage floors and parked into an appropriate space with security guarantee.
To command and coordinate all the controllers and subsystems, automated parking systems require precise control, robust and reliable networking, and secured system maintenance.
Conventionally, the electromechanic systems driving the automatic parking and retrieval process are controlled by a PLC (programmable logic controller), with which parking attendants direct the system using a control panel at the entrance. The PLC is a closed system based on a unique programming language, and is often situated in a remote location, presenting inconvenience when data is to be read from the PLC unit via an HMI device linked by an RS-485 serial cable.
Using an Internet of Things (IoT) gateway to connect with the PLC, however, sensors and other edge devices, field data can be retrieved, analyzed and stored to the cloud. This allows the parking system to be monitored and controlled from a remote control center in real time, providing considerable benefits to the management and efficiency of the parking systems.
The IoT gateway links the PLC with the PC-based monitoring control system, allowing PLC data to be read and basic repair and maintenance tasks executed by way of a handheld panel or other mobile device linked to the network via 3G/WiFi or other Ethernet connection.
As IoT gateways continually upload the PLC data to local servers and the cloud, operating status from multiple towers can be remotely monitored in real time, alerting admin to problems which can be alleviated in a timely manner. Risk of system failure and the requirements of onsite maintenance are thus minimized, improving efficiency and reducing maintenance costs.
Further, with cloud computing enabled by IoT technology, new applications can be developed to increase value-added services. A smart city parking system can be developed that enables drivers to locate nearby parking vacancies through a GPS/web-based mobile device accessing cloud information.
Since automated parking garages represent a significant investment, connection of existing PLC systems and equipment to external facilities requires a reliable, cost-effective IoT solution. A favorable IoT solution must make it easy to upload field data to the cloud with no need to abandon established assets, all with minimum additional investment, reduced maintenance burden and cost, and maximized ROI.
ADLINK's Matrix MXE-200i and MXE-100i IoT gateways, based on the Intel® IoT Gateway platform, offer an excellent choice of computing power. Combining the advantages of the Wind River Intelligent Device Platform XT, McAfee Embedded Control, and ADLINK's SEMA Cloud, the MXE-200i and MXE-100i provide pre-integrated, pre-validated hard-and-software building blocks that deliver all the necessary computing, communication, connectivity, security, and manageability capabilities to establish an industrial-grade cloud-based IoT application.
In an automated parking system environment, the MXE-200i can be installed at the entrance of the parking complex, connecting to payment card readers and camera sensors reading plate numbers and vehicle dimensions. The MXE-200i, powered by the Intel® AtomTM processor E3845 or E3826, offers flexible and rich I/O and enable primary image processing and analytics before transmitting results to the local MXE-5400 server. This server gathers data from all gateways for local intelligent applications and forwards application-specific data to the cloud.
Once a vehicle's dimensions are determined by this system, a vehicle can be assigned to the nearest spot of minimally appropriate size. This intelligent approach increases efficiency of space utilization and is just one example of the benefits intelligent systems can deliver.
The MXE-100i connects to and collects data from the PLC, which is then transmitted in PC-based formats to the local server. Accordingly, data concerning the operating state of the automated parking system enables real-time monitoring, reducing the need for onsite visits and thus reducing maintenance costs and increasing efficiency.
The ADLINK-Intel IoT solution for automated parking systems presents an application-ready platform, enabling system integrators to quickly develop and deploy IoT applications, enabling real time, remote facility monitoring and advanced cloud services without affecting legacy infrastructure. Increases in capital investment for the parking facility are minimal while resulting benefits are considerable, including reduced maintenance costs and enhanced operational efficiency.
System integrators and service providers for automated parking systems can use the ADLINK IoT solution to gain a significant edge in market competitiveness and speed their solutions to market.
