Principle and typical architecture of an industrial FPGA system
An FPGA system сconsists of a power supply, a CPU, and several analog and digital I / O modules that can control, execute, and monitor complex machine variables; The FPGA is designed for multiple I / O configurations and is expandable.
Temperature range, excellent electrical noise suppression performance, shock resistance.
The FPGA system includes power, control and communication modules, as well as various analog input, analog output, digital input and digital output modules.
Recommendations for the design of industrial FPGA systems and the main problems
To obtain a suitable FPGA system design, designers must consider many different system requirements, including accuracy, bandwidth, and input range. Analog input type and range: for thermocouple and RTD, it can be as low as 10 mV; for drive controllers it can be as high as 10 V or 4 mA to 20 mA in process control systems.
- Current. Analog Output Type and Range: Typically includes 5V, 10V, 0V to 5V, 0V to 10V, 4mA to 20mA, and 0mA to 20mA. Out of range is sometimes required.
- I / O module resolution and accuracy: 12 to 16 bit typical range, 0.1% industrial temperature accuracy. Connect to different fieldbuses.
- Insulation: between power modules of the system and low-power electronic devices, between input and output, between inputs and outputs and the central control unit, the insulation level is from 1 kV to 2.5 kV.
- Analog Input Output and Input Power Protection: Voltage or current failure conditions and EMC considerations including surges, fast transients and ESD. As the size of printed circuit boards decreases, energy efficiency, temperature control and heat dissipation will become increasingly important issues for miniature devices.
In addition, more channels or nodes need to be placed in the same space, which requires a high-density system. Therefore, the size of the device needs to be reduced. This means that the body is smaller, which brings in electricity.
Power management and heat dissipation problems, so a smart power management solution through integrated dynamic power management is needed.
In the past, implementing this type of I / O system required a large number of high-performance discrete components, resulting in a large and expensive system. Recently, advances in integration technology have allowed system designers to apply them.
Use a smaller size, lower power consumption, cheaper solutions, and its performance is comparable to that of large-scale systems. For continuous technical progress it is necessary that both the continuous advancement of these sets of solutions. It also improves its performance and diagnostic capabilities.
