While home automation first put the Internet of Things concept into the technology mainstream, industrial IoT is where this nascent high-tech sector’s growth truly lies. Companies of all sizes, spanning many different industries, hope to gain a competitive advantage using a variety of IoT applications.
A typical industrial IoT scenario involves data from sensors embedded inside equipment that communicates with a small gateway computer connected to the Internet. A remote data analyst or engineer uses this information in a myriad of ways. The ultimate goal of the application could be optimizing performance by detecting either hardware breakdowns or simply inefficient operation.
Frankly, this is only one of many different possibilities. Let’s dive into some reasons why the time for industrial IoT is today.
The TS-ADC24 can provide up to 8 MB/s of ADC data, but the ISA (PC/104) bus on most systems is limited to 2 MB/s bandwidth or less. So one might conclude that the TS-ADC24 is over-designed. However, the TS-ADC24 itself does not require the long ISA strobe times that typical PC/104 systems use, and a well-designed PC/104 system such as the TS-8100-4740 featuring a Spartan 6 FPGA can actually exceed 2MB/s for sustained bursts. This translates into sampling 4 ADC channels at 250 kHz or even 500 kHz. This is possible due to standard functionality in the FPGA including customizable bus timing, user DMA, and an embedded processor. With extra engineering, 1000 kHz would be possible, but this article explores what can be accomplished by a typical C programmer who does not want to venture into the realm of FPGA development.
