Multi-device serial communication technology enables data exchange between the system and multiple peripheral devices through serial interfaces. Its design is based on serial communication protocols such as UART or RS-232, and utilizes hardware interrupts and buffer management to coordinate concurrent access, thereby improving communication efficiency. The advantages of this approach are simplified hardware connections, reduced power consumption, and enhanced anti-interference capabilities. It is suitable for the harsh environment of satellites. Through logical address allocation and error detection mechanisms, the system can reliably transmit commands and telemetry data, supporting mission-critical operations.

The present invention provided by various embodiments will be described in detail below with reference to the accompanying drawings. To better understand the purpose of the present invention, the present invention will be described in further detail below.

[0064] Please see Figure 1 The present invention provides a configuration method for a multi-device polling communication system based on a UART controller, comprising:

[0065] Step 1: Collect serial communication parameters and initial status information of multiple devices through the UART controller hardware interface, obtain device type identifier, data buffer address, communication cycle parameters and initial status flag, and store the collected data in a temporary configuration buffer;

[0066] Step 2: Initialize the main configuration structure array using the device parameters in the temporary configuration buffer. The main configuration structure includes fields for device name, data receive buffer pointer, power-on wait time, data receive cycle, wait strategy, data receive function and parsing function. A configuration version management mechanism records structure changes.

[0067] Step 3: Initialize the slave device status structure array based on the device parameters in the master configuration structure. The slave device status structure includes the device name, data content identifier, data receive buffer pointer, timestamp, data packet status and sending status fields. The time series prediction mechanism builds a prediction model based on historical status data.

[0068] Step 4: Set the serial port communication parameters of each device using the communication cycle and waiting policy parameters in the main configuration structure. The policy distribution mechanism allocates differentiated configurations based on the device type identifier.

[0069] Step 5: Execute polling scheduling, use the periodic parameters and priority algorithm defined in the main configuration structure to access each device, the UART controller receives data from the serial port to the position specified by the data receive buffer pointer, and calls the data receive function and parsing function to process the data;

[0070] Step 6: Update the device status structure. After data parsing is complete, adjust the timestamp and data packet status, monitor the sending status, and use the status consistency verification algorithm to verify the status data. This completes the centralized control and status tracking of multi-device serial communication.

[0071] The UART controller hardware interface is used to collect serial communication parameters and initial status information from multiple devices, obtaining device type identifiers, data buffer addresses, communication cycle parameters, and initial status flags. The collected data is then stored in a temporary configuration buffer. Specifically, the UART controller is accessed via memory-mapped registers to obtain the current values ​​of each device's configuration registers. These register values ​​are then transferred via DMA to a double-buffered temporary configuration area. A CRC check is performed on the data in the temporary configuration area, and finally, data that passes the CRC check is stored in the temporary configuration buffer.

[0072] The main configuration structure array is initialized using device parameters from the temporary configuration buffer. The main configuration structure includes fields for device name, data receive buffer pointer, power-on wait time, data receive cycle, wait strategy, data receive function, and parsing function. A configuration version management mechanism records structure changes. Specifically, a configuration version management table is created, containing the configuration version number and update timestamp for each device. Pointer swapping is used to load the data from the temporary configuration buffer into the runtime environment. The version number in the configuration version management table is compared with the current runtime version number, and the result of the version number comparison determines whether to allocate an independent configuration segment for the device type.

[0073] The slave device state structure array is initialized based on the device parameters in the master configuration structure. Each slave device state structure includes the device name, data content identifier, data receive buffer pointer, timestamp, data packet status, and transmission status fields. A time series prediction mechanism builds a prediction model based on historical state data. Specifically, a five-state machine model is constructed, encompassing initialization, ready, transmission, verification, and completion states. A corresponding state machine instance is created for each device instance. A time series prediction algorithm processes historical communication data to generate device state change trend predictions, and system resources are pre-allocated based on these predictions.

[0074] The application's main configuration structure sets the serial port communication parameters for each device using the communication cycle and waiting policy parameters. The policy distribution mechanism allocates differentiated configurations based on the device type identifier. Specifically, it parses the device type identifier, matches it with a predefined policy template, uses bit-field encoding technology to process differentiated parameters, compresses storage space, retrieves device-specific configuration parameters by querying the configuration table, and adjusts the policy parameters according to changes in the device's state during runtime.

[0075] The system executes a polling schedule, accessing each device using the periodic parameters and priority algorithm defined in the main configuration structure. The UART controller receives data from the serial port to the specified position in the data receive buffer pointer, and calls the data receive function and parsing function to process the data. Specifically, it uses the periodic parameters in the main configuration structure to generate a device access sequence, adjusts the polling interval according to the importance of the device and the urgency of the data, applies an interrupt mask to handle device access conflicts, and executes the data receive function and parsing function to process the received data.

[0076] The process involves updating the device state structure, adjusting timestamps and data packet states after data parsing, monitoring transmission status, and using a state consistency verification algorithm to validate state data. This enables centralized control and state tracking of multi-device serial communication. Specifically, it performs hash verification on the parsed data to verify state data integrity, compares the current state with the updated state, modifies only changed state fields, synchronizes the state update sequence of multiple devices using timestamps, and provides the updated state data for use in the next round of scheduling.

[0080] Perform CRC check on the data in the temporary configuration area;

[0081] Data that passes the CRC check is stored in a temporary configuration buffer.

[0082] In step 1, this invention accesses the UART controller via memory-mapped registers to directly read the current values ​​of each device's configuration registers, achieving efficient acquisition of hardware parameters. Subsequently, the acquired register values ​​are transferred via DMA and stored in a temporary configuration area with a double-buffered structure, leveraging DMA's direct memory access feature to reduce CPU overhead. A CRC check is performed on the data in the temporary configuration area to verify data integrity. Finally, data that passes the CRC check is stored in a temporary configuration buffer, providing a reliable data foundation for subsequent configuration initialization. These steps are logically connected, from hardware interface acquisition to data storage, ensuring the accuracy and efficiency of parameter acquisition.

[0086] Compare the version number in the configuration version management table with the currently running version number;

[0087] The decision on whether to assign a separate configuration segment to the device type is based on the version number comparison result.

[0088] In step 2 of this invention, a configuration version management table is created, and the configuration version number and update timestamp of each device are written to achieve configuration history tracking. Pointer swapping technology is used to load data from the temporary configuration buffer into the runtime environment, enabling rapid configuration switching through pointer operations without data copying. The version number in the configuration version management table is compared with the current running version number to identify configuration changes. Based on the version number comparison result, a decision is made on whether to allocate an independent configuration segment for the device type, thereby supporting dynamic configuration management. This step forms a complete process for version control and configuration loading, enhancing system adaptability and maintainability.

A policy distribution mechanism dynamically adjusts parameter configurations, eliminating the risk of configuration errors caused by manual intervention. An intelligent polling scheduling algorithm adaptively adjusts the access order based on device importance and data urgency, effectively preventing device access conflicts in conjunction with an interrupt masking mechanism. Furthermore, through a configuration-state linkage design, state synchronization is automatically triggered when a configuration update is detected, achieving collaborative management of parameters and states.
