“Microkernel” Technology
Powsde-RTOS is an embedded real-time multitasking operating system (ME-RTOS: Microkernel Embedded RTOS) with "microkernel" technology. It does not have the large and heavy "software baggage" of conventional software, so the system is stable and solid, and its own refinement maximizes efficiency.
Exquisite "Embedded" Technology
Powsde-RTOS has powerful functions while occupying only more than ten KB of memory. After functional expansion (for example, adding the window interface of Micro-GUI), it is only a few hundred KB. It embodies "embedded" to the fullest. It enables users to embed software into chips or electronic disks. Exquisite embedded products will win more markets, and development and upgrades are simple and easy.
Rapid Real-Time Multitask (Real-time Multitask) Features
Because the Powsde-RTOS system adopts "Microkernel Embedded Real-Time Multitask Operating System (Microkernel Embedded RTOS)", and the application layer code adopts "multi-process (Multi-process) programming", it performs exceptionally well in real-time multitasking. Task concurrent processing is easy. In terms of real-time multitask concurrent processing, it is beyond the reach of single-task operating systems or "single-process (Simplex-process) software" under multitask systems. According to the corresponding programming mode, after configuration, the system can select operating modes with respective advantages according to the number and characteristics of application tasks: absolute preemptive, task cooperative.
The system embeds "micro database management system MDBMS"
The biggest feature of the "micro database management system MDBMS (Micro-Database Manage System)" embedded in Powsde-RTOS is: it is both a "micro Micro" system and can be partially compatible with mainstream large commercial databases (such as SQL, ORACLE, SYBASE, etc.). The original data files processed by the system can be directly recognized and read into the database by mainstream large commercial databases. Therefore, in some large systems, many intermediate systems can be omitted, and data can be directly entered into the server database.
The system time has directly adopted the built-in "Julian day counting method" (JD)
Because Powsde-RTOS directly adopts the Julian (JD) day counting method (Julian day counting method or Caesar day counting method) commonly used in academia, continuous calendar and time-related scientific calculations span several billion years, without the "millennium" problem, commonly known as astronomical calendar. In various large database programs (such as SQL, ORACLE, SYBASE, etc.), there are calendar kernel programs related to this without exception. Especially in large systems that need to perform massive data analysis on the timeline, the intelligent devices composed of this system all have JD time stamps when processing pre-real-time data, thus bringing great convenience to large background systems.
The system embeds "micro graphical user interface interface POWSDE Micro-GUI"
The "micro graphical user interface interface Micro-GUI" embedded in Powsde-RTOS is 100% Chinese-ized, completely compatible with the mainstream window interface operation style and usage habits. "Windows, panels, buttons, icons", etc. are all available. It is easy to get started and operate freely for the first time, just like on the desktop system. The resolution supports 128X64, 320X240, 640X480, 800X600, 1024X768, and non-standard sizes. The color supports 2 colors, 8 colors, 16 colors, 256 colors, and 16 bits. The screen effects support: background automatic cache and recovery, saving or loading images in a data stream manner, visual animations, etc.
The system supports "dynamic skin change" technology
POWSDE Micro-GUI supports "dynamic skin change" technology, so that the interface color of industrial products can also meet the personalized or customized needs of users. It also has the "root window (Boot Window)" feature.
The system embeds "direct chip driver DCD technology"
The Powsde-RTOS system adopts "direct chip driver DCD technology (Direct Chipset Driver)" for all communication ports. It directly drives the registers of the communication port hardware chip and directly reads and writes the data stream of the communication port, instead of using the interrupt call of the BIOS system software for driving and reading and writing data. This avoids the overhead and data transfer when calling BIOS, improves the reliability of data and transmission time. It supports real-time concurrent operation of communication port data communication. At the same time, all communication ports are equipped with variable input and output buffers. The buffer is a variable circular linked list instead of a fixed-size linear linked list. Users can flexibly configure and monitor parameters such as the total capacity, number of linked nodes, and single table capacity of this circular linked list according to actual conditions.

Communication port monitoring 2
The system embeds "file transfer protocol POWSDE Micro-FTP"
The simplified "file transfer protocol FTP (File Transfer Protocol)" function embedded in the Powsde-RTOS system brings convenience and functional extension to "remote file download, remote online software upgrade".
The system communication port adopts "dynamic protocol" technology
All communication ports of the Powsde-RTOS system can adopt "dynamic protocol" switching technology. The same communication port can access external sensors or data devices from different manufacturers with different protocols. When replacing external sensors or data devices from different manufacturers with different protocols, it is only necessary to open the setting window to set different protocol codes for the external sensors or data devices under the same communication port. The same communication port can also be dynamically configured as an "uplink remote communication port" or a "downlink local communication port" according to the actual wiring.
The system adopts hierarchical dynamic user management and permission management
The Powsde-RTOS system introduces and adopts hierarchical dynamic user permission management similar to the large commercial system. Users with different permissions have completely isolated, different, and private window menus and function systems. Therefore, users need to log in like in large systems before performing any operation, and there is SOE sequence log recording, which brings convenience to the operation and management of the equipment.
The system supports "remote maintenance, online upgrade"
The Powsde-RTOS system supports "remote maintenance" and has many characteristics. It supports remote start/stop, remote parameter setting, remote file download, remote online software upgrade, remote diagnosis and other remote maintenance functions.
