Based on a triple modular redundant architecture, it ensures reliability through hardware voting, adapts to analog and digital signal processing, and supports high-speed bus communication. It features high fault tolerance, strong computing capability, and adaptability to harsh industrial environments, allowing online maintenance and expansion. It is widely used in automation systems of industries such as petroleum, chemical engineering, and electric power.
Product Features
High Reliability: The triple modular redundant structure design endows it with excellent fault tolerance. Even if any one channel fails, the system can still operate normally, and there will be no system failure due to a single point of failure. In industries such as petrochemicals that have extremely high safety requirements, even if some hardware fails, the continuity and safety of the production process can be guaranteed, effectively reducing the risk of production accidents caused by system failures.
Powerful Computing Capacity: Adopting advanced microprocessor technology, it has high-speed data processing capability and can quickly respond to complex control tasks and a large number of data computing needs. In high-speed automated production lines, it can process a large amount of equipment status data in real time and quickly make control decisions, ensuring the efficient and stable operation of the production line.
Good Environmental Adaptability: The shell is designed to be sturdy and durable, and the internal circuit has undergone special treatment, which can adapt to harsh industrial environments such as high temperature, high humidity, and strong electromagnetic interference. It can work stably whether in oil extraction facilities in deserts or humid offshore oil platforms, ensuring the reliable operation of industrial control systems.
Easy Maintenance and Expansion: The standardized design makes its installation, maintenance and upgrade extremely convenient. It supports online plugging and replacement of faulty modules, and faulty modules can be repaired or replaced without interrupting the system operation, which greatly reduces system downtime. At the same time, the module has good expandability, and related functional modules can be flexibly added or reduced according to actual needs to meet the requirements of industrial control systems of different scales and complexities.
Working Principle
Operation based on Triple-Modular Redundant (TMR) architecture: The AI2361 adopts an advanced triple-modular redundant structure, containing three independent and identical processing channels. Each channel can independently execute the control program and process input data. Taking digital input as an example, the three channels receive digital signals from field devices simultaneously, and then a hardware voting mechanism compares and judges these signals. If the results of two or more of the three channels are consistent, this result is recognized as a valid output, thus effectively avoiding the impact of single-point faults on the system.
Analog signal processing flow: For analog input signals, the front-end signal conditioning circuit first performs preprocessing such as filtering and amplification on the signals from field sensors to ensure the stability and accuracy of the signals. The preprocessed signals are transmitted to the three processing channels respectively. The analog-to-digital converter (ADC) in each channel converts the analog signals into digital signals, and then the digital signals enter the microprocessor of each channel for arithmetic processing. Finally, through the median selection algorithm, the median value is selected from the processed results of the three channels as the final analog output result. This method further improves the reliability and accuracy of analog processing.
Cooperative working mechanism with other modules: It communicates with other modules through a high-speed and reliable internal bus (such as TRIBUS). When interacting with input and output modules, it obtains real-time status data of field devices from the input module, processes it, and then sends control signals to the output module to drive the actuator to act. At the same time, it also cooperates with the communication module to transmit internal system data to external monitoring systems or other related devices, realizing remote monitoring and data sharing.
Application Fields
Oil and Gas Industry: It is used in building Safety Instrumented Systems (SIS) and Process Control Systems (PCS) in links such as oil extraction, transportation, and natural gas processing. For example, it conducts real-time monitoring and control of various equipment on oil drilling platforms to ensure their safe and stable operation; in natural gas transmission pipelines, it precisely controls parameters like pressure and flow to guarantee the safety and reliability of the transmission process.
Chemical Industry: It is widely applied in key links of chemical production processes, including reaction control, distillation tower control, and material transportation control. Through accurate monitoring and control of various process parameters, it ensures the efficiency, stability, and safety of chemical production processes, preventing safety accidents and quality issues caused by improper control.
Power Industry: It plays an important role in unit control of power plants, automated monitoring of substations, and dispatching management of power grids. For instance, it coordinates and controls equipment such as boilers and steam turbines in thermal power plants to achieve optimized operation of the power generation process; in substations, it monitors the operating status of electrical equipment in real-time, promptly detecting and addressing potential faults.
Industrial Automated Production Lines: It is used for the overall control and scheduling of automated production lines, realizing the collaborative work of equipment and the automated operation of production processes. In automated production lines of industries such as automobile manufacturing and electronic equipment production, it ensures precise control and efficient connection of each production link, improving production efficiency and product quality.
