Working Principle
When the device is connected to an industrial automation system, it first receives analog signals from various sensors (such as temperature sensors, pressure sensors, flow sensors, etc.) and digital signals from devices such as switches and relays through input interfaces. For analog signals, the internal signal conditioning circuit of the device performs preprocessing such as filtering, amplification, and linearization to eliminate noise and interference in the signals, making them meet the input requirements of the A/D converter, which then converts the analog signals into digital signals. Digital signals are directly processed by level conversion and isolation circuits before being transmitted to the core control unit.
The core control unit is typically composed of high-performance microprocessors or FPGAs, which perform real-time analysis and calculation on the input digital signals based on the control logic and algorithms preset by users through configuration software, as well as the set parameters of system operation. For example, in a temperature control system, the core control unit compares the current temperature detection value with the set temperature value. If there is a deviation, it calculates the control quantity to be output according to the preset control algorithm (such as the PID control algorithm).
If the calculated control quantity is an analog quantity, it is converted into an analog control signal by the D/A converter, amplified by the output drive circuit, and then transmitted to actuators such as control valves and frequency converters to achieve equipment adjustment. If it is a digital quantity, it directly drives relays, contactors, and other devices through digital output channels to control the start/stop or status switching of equipment. Throughout the operation process, the device interacts with the upper-level control system or other devices in real time through the communication interface according to the selected industrial communication protocol, uploading equipment operation status information and receiving control commands and parameter adjustment information, thus realizing closed-loop control and intelligent management of the industrial automation system.
