Intewell is an industrial embedded real-time operating system independently developed by Kedong Software, which has the characteristics of high real-time, determinism, high security, high reliability, and virtualization. The Intewell system originated from the "Tao" operating system that was born in 1990. It has a history of more than 30 years. It has been tested in various harsh environments and is widely used in industrial control, intelligent manufacturing, automotive electronics, rail transit, and aerospace. , robotics, automation, energy and electricity, medical equipment and other fields. The Intewell operating system adopts a microkernel structure design, which has a high degree of modularity, and can be customized according to the needs of application scenarios.
Intewell-Win is a real-time extension of Windows and one of the product forms of Intewell-H. Based on a multi-core processor, the system realizes the parallel operation of Windows applications and real-time applications, and the Windows system and Intewell real-time system are safely isolated, which is compatible with the rich ecology of Windows and ensures the real-time performance and determinism of real-time system tasks.

09. Support Modbus, CANopen, EtherCAT and other industrial bus protocols;
10. Support industrial control software Codesys, MaVIEW, etc. based on IEC61131-3 standard programming;
Kedong Software Intewell-win system performance data
Test requirements:
Running the intewell-Win operating system on a certain brand of Core i5 industrial computer hardware platform, under the 250us task cycle, the bus task timing jitter is required to be within 5% (12.5us).
Real-time load test conditions:
The two RTOSs respectively run the Ethercat master station to drive 21 EtherCAT bus servos of a certain brand with a 250us scan cycle.
Non-real-time load test conditions:
BurnInTest sets CPU load (50%), Disk load (100%), RAM load (50%), Network load (50%), VideoPlay-back load (50%), 2D load (50%) and 3D load (50%) %).
Actual test data:
Test conclusion:
The timing jitter of the bus task is within 5% of the task cycle, and the test data requirements in the most stringent test scenarios above are passed, and the test results basically meet the test requirements.
Intewell-Win application field

Intewell-Win application case
Case 1: Building a software-defined control automation production line based on Intewell-Win
Business pain points:
An automated production line requires 13 workstation PLCs and 1 master PLC for real-time logic control and motion control of equipment, and additional industrial computers for HMI interface and visual inspection. The network is complex, there are many devices, and development, operation and maintenance are difficult. big.
solution:
Intewell-Win is applied to the transformation project of the smart factory product line. Based on the edge controller hardware, 13 RTOSs are virtualized in the real-time part, and 13 PLC applications are run respectively to control the slave stations of the equipment under different stations, software-defined Control automated production lines, high integration, simplified and reliable network.
value of customer:
1) One controller replaces multiple PLC devices and industrial computers, simplifying wiring and reducing hardware costs;
2) Multiple RTOSs are provided through virtualization on the real-time side to meet the needs of multiple different control tasks;
3) RTOS applications realize data interaction through shared memory, which is efficient, stable and reliable.
