[0002] With the rapid development of science and technology, industrial automation has become the core driving force of modern manufacturing, greatly improving production efficiency, product quality and production flexibility. In this process, the distributed control system (DCS), as a key component in the field of industrial automation, undertakes the task of monitoring, controlling and optimizing complex production processes. Through its distributed architecture, the DCS system distributes control functions to multiple controllers, and the controllers communicate and collaborate through the network to achieve precise control of the entire production process.

[0003] However, with the continuous improvement of industrial automation level, production systems are becoming increasingly complex, and the software logic carried by DCS controllers is becoming increasingly large and complex.

During the restart process, the trusted computing module records and verifies the following key information in real time: System call sequence; Key variables and memory states; Process and module loading status; Network interface and communication status; Compare and verify the key variables and memory status, process and module loading status, network interface and communication status with historical normal status or preset safety benchmarks to ensure the accuracy and safety of the restart process; After the restart is completed, the software's operating status is verified by comparing the system status and data integrity before and after the restart; if the status is abnormal, an alarm message is issued and an attempt is made to restore the software to the target version status.

[0007] Furthermore, the monitoring indicators of the operating status of the DCS controller software include system performance monitoring indicators, system health monitoring indicators, safety monitoring indicators, and real-time and stability monitoring indicators.

[0008] Further, the performing of integrity check on the hardware and software of the DCS controller includes: Use the security mechanism of the trusted computing module to verify the software code, check the hardware connection status, and verify the consistency between the current version of the software and the target version; The target version is the original version of the software.

[0009] Furthermore, the security mechanism includes digital signcryption verification or hash comparison.

[0010] Further, the restart process includes: Trigger a restart signal to restart the software; The trusted computing module logs specific operating events of the DCS controller software system in real time.

[0014] In a fourth aspect, the present invention provides a computer program product, wherein the computer program product includes computer instructions, and the computer instructions instruct a computer to execute the above-mentioned DCS controller software restart method based on trusted computing.

[0015] In a fifth aspect, the present invention provides a DCS controller software restart system based on trusted computing, comprising: An integrity check module is used to monitor the running status of the DCS controller software in real time; a trusted computing module is integrated in the DCS controller; the trusted computing module is used to monitor and verify the running status of the DCS controller software; The restart module is used to perform integrity checks on the hardware and software of the DCS controller when the trusted computing module receives a target instruction, wherein the target instruction includes a software abnormality instruction and a software restart instruction.

The real-time monitoring function of the trusted computing module can timely discover potential problems or abnormal states in the DCS controller software, such as memory leaks, dead loops, etc. Once these problems are detected, the module will respond quickly and trigger the target process through a restart instruction, thereby effectively avoiding the occurrence of system crashes or instability. This proactive monitoring and response mechanism significantly improves the stability and reliability of the DCS control system. The trusted computing module not only monitors the software running status, but also performs hardware and software integrity checks. This step ensures that the DCS controller is not illegally tampered with or implanted with malicious code before restarting, thereby effectively preventing potential security threats. When the trusted computing module receives the restart instruction, it automatically executes a series of orderly steps to ensure the safety and smoothness of the restart process. First, an integrity check is performed to ensure that the hardware and software are in a normal state; then a restart operation is performed; and finally, the software running state is verified to ensure that the system has resumed normal operation. This process not only shortens the fault recovery time, but also reduces additional problems that may be caused by improper restarting, and improves the efficiency and accuracy of fault handling. Through real-time monitoring and intelligent restart mechanisms, the technical solution makes the maintenance of the DCS controller simpler and more efficient. Maintenance personnel can locate the root cause of the problem more quickly and reduce downtime caused by software failures. At the same time, because the system can automatically perform some recovery operations, it also reduces the reliance on manual intervention, optionally reducing maintenance costs and time costs. Through real-time monitoring and intelligent restart mechanisms, DCS controllers can better adapt to complex and changing operating environments. Whether it is a short-term anomaly caused by external interference or a long-term accumulated error of the software itself, the system can detect and handle it in time, thereby enhancing the system's adaptability and fault tolerance. This capability is essential to ensure the continuity and stability of industrial automation production.

[0017] Optionally, the DCS controller software restart method of trusted computing introduces an integrity check step for the DCS controller hardware and software; the software code is verified by the built-in security mechanism of the trusted computing module to ensure that the software code has not been tampered with or implanted with malicious code before and after the restart. It can effectively prevent the software from being illegally modified, thereby protecting the system from malicious attacks and data leakage risks. By monitoring the connection status of hardware devices, signal transmission quality and other parameters, hardware failures or connection problems can be discovered and solved in a timely manner to avoid system instability or data loss caused by hardware failures. This helps to ensure that the DCS controller can run stably and reliably after restart. By comparing the current software version with the preset fixed version, it can be ensured that there is no unexpected version change or downgrade of the software during the restart process; by recording in detail any problems, anomalies or errors found during the inspection process, it can provide a strong basis for subsequent troubleshooting and repair. This helps to quickly locate the root cause of the problem, reduce troubleshooting time, and improve the maintainability and availability of the system. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. The components of the embodiments of the present invention described and marked in the drawings here can be arranged and designed in various different configurations.

[0022] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the invention claimed for protection, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0023] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, it need not be optionally defined and explained in subsequent drawings.

[0024] The present invention is described in detail below in conjunction with the accompanying drawings: See also Figure 1 The present invention discloses a DCS controller software restart method based on trusted computing, comprising the following steps: S1, real-time monitoring of the running status of the DCS controller software. The DCS controller software is integrated with a trusted computing module; the trusted computing module is used to monitor and verify the running status of the DCS controller software; After the DCS controller software is started, the trusted computing module immediately enters the working state and begins to monitor the software running status of the controller in real time, including key indicators such as memory usage, CPU usage, and network communication status.

[0025] S2, when the trusted computing module receives the target instruction, it performs integrity check on the hardware and software of the DCS controller, and the target instruction includes: software abnormality instruction and software restart instruction.

[0026] When the DCS controller software is abnormal (such as software crash, slow response, etc.), or receives an external preset restart instruction, the trusted computing module will receive the restart instruction. The restart instruction includes software abnormality instruction and software restart instruction. The software abnormality instruction is automatically generated by the trusted computing module based on the monitoring results, while the software restart instruction is triggered by the system administrator through the remote operation interface or the preset timed task.

[0027] The integrity check of the DCS controller hardware and software includes: using the advanced security mechanism built into the trusted computing module to verify the software code. Among them, the security mechanism includes digital signature verification and hash comparison. In terms of digital signature verification, the software developer attaches an authoritative digital signature to the DCS controller software when releasing it, and the trusted computing module uses the corresponding public key to perform strict verification to ensure the legitimacy of the software source and the state that it has not been tampered with. Hash comparison is to calculate the hash value of the software code and accurately compare it with the pre-stored hash value of the original software version, so as to effectively detect whether the software has been illegally modified during storage and operation.

[0028] At the same time, the hardware connection status is carefully checked, including whether the hardware interfaces are connected normally, such as whether the communication lines between the controller and the sensor and actuator are unobstructed, whether the hardware module is powered normally, etc. Ensure the stability and reliability of the hardware foundation to provide a solid guarantee for the normal operation of the software.

[0029] S3, after confirming that the integrity of the hardware and software is normal, the trusted computing module automatically triggers the restart process.

[0030] When the integrity check of both hardware and software passes and no abnormalities are found, the trusted computing module will perform a software restart operation. First, the trusted computing module will save the key information of the current software status (such as configuration parameters, operating status, etc.), then safely shut down the DCS controller software, and restart it.

[0031] During the restart process, the trusted computing module records and verifies the following key information in real time: System call sequence; Key variables and memory states; Process and module loading status; Network interface and communication status; The key variables and memory status, process and module loading status, network interface and communication status are compared and verified with historical normal status or preset safety benchmarks to ensure the accuracy and safety of the restart process.

[0032] After the restart is complete, verify the software running status to ensure that the software is running normally. That is, after the restart is completed, verify the software running status by comparing the system status and data integrity before and after the restart; if the status is abnormal, issue an alarm message and try to restore the software to the target version status.

[0033] After the software restart is complete, the trusted computing module will monitor and verify the software's operating status again. This includes checking whether the software has been successfully started, whether each functional module is running normally, whether key performance indicators meet the requirements, etc. This ensures that the software can run normally and stably after the restart, and avoids system anomalies or failures caused by improper restart operations.

[0034] An embodiment of the present invention shows a specific implementation process of a DCS controller software restart method based on trusted computing. The method monitors and verifies the running status of the controller in real time through a trusted computing module integrated in the DCS controller software, ensuring that the restart operation can be performed safely and reliably when restart is required, thereby maintaining the stability and security of the system; specifically, the following steps are included: Monitor the running status of DCS controller software in real time.

[0035] Monitoring indicators include system performance monitoring indicators (such as CPU usage, memory occupancy), system health monitoring indicators (such as disk space, network communication status), security monitoring indicators (such as security logs, firewall status) and real-time and stability monitoring indicators (such as response time, fault recovery time).

[0036] As a core component, the trusted computing module is responsible for monitoring and verifying the operating status of the DCS controller software to ensure data accuracy and system security.

[0037] Restart command reception.

[0038] When receiving a software exception instruction or a software restart instruction, the trusted computing module prepares to perform preparatory work before restarting. Restart instruction types include software exception instructions (automatically generated by the trusted computing module based on monitoring results) and software restart instructions (triggered by the system administrator or preset tasks).

[0039] Integrity check.

[0040] Use digital signature verification or hash comparison and other technical means to verify the software code of the DCS controller to ensure that the software has not been tampered with. Check the hardware connection status to ensure that all hardware devices are in a normal connection state. Verify the fixed version to ensure that the software version meets the preset requirements to avoid compatibility issues caused by inconsistent versions. Record the inspection results to provide a basis for subsequent analysis and troubleshooting.

[0041] The software restarts.

[0042] After confirming that the hardware and software integrity are normal, the restart signal is triggered. The trusted computing module records and verifies the status of the DCS controller software in real time during the restart process to ensure a smooth restart process.

[0043] Verify after reboot.

[0044] After the restart is complete, the trusted computing module verifies the system status and data integrity again. By comparing key indicators before and after the restart (such as system configuration, operating parameters, data integrity, etc.), it ensures that the software has returned to normal operation. If the verification fails, it re-enters the monitoring phase for troubleshooting and processing.

[0045] An embodiment of the present invention provides an electronic device that integrates a DCS controller software restart method based on trusted computing. The electronic device implements real-time monitoring, integrity check, safe restart, and post-restart status verification of the DCS controller software running status through a built-in memory, a processor, and a computer program stored and running on the processor, thereby ensuring the high availability and security of the DCS system.
