As today's computing environment becomes increasingly complex and is subjected to ongoing change, the need to capture and analyze the data is quickly becoming a very real need to closely monitor conditions in the data acquisition industry.
A typical data acquisition system collects the data from various sites and makes it available in a central location for subsequent processing. Examples of use include simple electronic gathering of data from oil wells to remote operation of an unmanned oil or gas platform. Other typical applications might be storage tank farm management, water/steam injection, pipeline management, metering stations, steam generator and compressor stations, etc.
In the past, remote management of sensor data has taken the form of manual operations. This approach limits the capability and efficiency of data acquisition systems. In addition, manual operations require experienced, and highly skilled operators.
On the other hand, the worldwide familiarity, and availability of Ethernet, along with its potential performance levels, has prompted increased consideration of Ethernet as a feasible communications technology for process control based data acquisition tasks. A TCP/IP based communications network would allow a wide variety of sensors, actuators, and other devices to be connected and managed over the network. In this network, sensors could be easily added to or removed from the system.
Responding to these trends, Sena is providing a TCP/IP-based Data Acquisition solution to collect the data from various process-control based devices and manage over the network.
The HelloDevice SS110 offers cost-effective network connectivity for the controller unit at the oil wells locations using TCP socket services, allowing them to be connected to the local network equipment. Each terminal unit has a variety of oil well measurement sensor and controllers attached to it. Through the ADSL network link, sensors and controllers at the individual oil well locations are now available to the district monitoring stations and the national management center.
The HelloDevice SS110 is featured with an industry standard RJ45 connector for RS232/422/485 based sensor connections and another RJ-45 socket for Ethernet connectivity. Full support for RS232 and RS422 control lines is available to make the HelloDevice SS110 compatible with sensor applications that require hardware and software handshaking.
Dynamic DNS feature of the SS110 allow controllers to be accessed over DSL-based broadband network or conventional LAN environment through the 10/100 Mbps Ethernet interface. On the other hand customer added a wireless LAN PC card into the PCMCIA slot of the 'HelloDevice SS110'. Powerful security features such as SSL, TLS, 3DES data encryption, and RC4 algorithm encouraging sensors to share the data with remote host securely.
