Modular data logger for wireless building automation
The TinyBox TBa53 can be integrated into a control cabinet as a DIN rail device, thus forming the basis for a system solution which can be implemented quickly. The TQ minimodule TQMa53, a high-performance Cortex-A8 module, is used in the process.
The data logger or the gateway makes a wide range of interfaces available to the user on the carrier board, such as RS232, 2x CAN (electrically isolated), 2x USB 2.0 and 2x Ethernet. To enhance it, an SD card interface accessible from the outside was installed.
In addition to the standard interfaces, the board is expandable via two expansion module plug-in connectors. These are of the same design and offer different interfaces (2x UART/SPI/I2C/USB/GPIO). Any number of expansion modules can be implemented on the basis of these interfaces.
Wireless solutions such as UMTS/GPRS, Wi-Fi as well as Bluetooth are planned in addition to the RS232 and RS485 expansion modules already available. Furthermore, various I/O features can be implemented on the expansion modules as well via the available interfaces.
Building automation company CoreNetiX is currently developing an expansion card on the basis of the CNX100 wireless radio module, operating in the 868 MHz frequency band. It offers a wireless BACnet access as well as a mesh network protocol stack which, thanks to its AES128 encryption, is also suitable for security-related applications. This serves as a basis for a BACnet implementation, optimized for embedded systems, which now allows the wireless integration of terminals into a BACnet environment as well.
A gateway constitutes the link between the wireless network and the wired world. In addition, it provides management systems with access to the BACnet devices in the wireless network.
Typical areas of application for the TinyBox TBa53 with long-term availability are multi-hop, mesh network solutions for applications in the sectors of building automation, smart metering, smart home, security & monitoring, industrial automation, process control as well as service management.
