This invention discloses a HART circuit and a method for determining the status of its field interface. The HART circuit includes: a control interface, an adjustable power supply module, a first HART module, an isolation module, and a field interface. The first HART module is connected to the control interface and is used to generate a first control signal when a first interrogation signal is input to the control interface. The adjustable power supply module is connected to both the control interface and the first HART module, and is used to output a first power signal to the control interface and modulate the first power signal into a first HART signal in response to the first control signal. The first end of the isolation module is connected to the control interface, and the isolation module is used to isolate the signal at its first end and couple it to its second end. The field interface is connected to the second end of the isolation module. This invention enables bidirectional communication between the control room and the production site, diversifies the application scenarios of the communication function of the HART circuit, and optimizes the performance of the HART circuit.

This invention discloses a levitation control method, equipment, and medium for conventional maglev trains, belonging to the field of maglev transportation control technology. The method constructs a control framework based on a dynamic model of the levitation system and introduces an online residual estimation and compensation mechanism to compensate for track irregularities, aerodynamic disturbances, and unmodeled dynamics under complex operating conditions. A lightweight data-driven model obtained through cloud-based large-scale model knowledge distillation is deployed in the onboard edge computing unit to model the temporal characteristics of system state, track features, and external environmental information, estimating disturbance residuals in real time and generating compensating control quantities that are superimposed on the control input. Simultaneously, the cloud continuously optimizes model parameters based on historical operating data and issues updates, achieving iterative optimization of the control strategy. This invention can significantly improve the stability, dynamic response performance, and operational safety of the maglev train levitation system under high-speed operating conditions.

This application provides a program execution method, apparatus, processor, chip, and electronic device. The method includes: determining a program to be executed; transmitting program information of the program to a security device, so that the security device matches the program with a whitelist based on the program information; receiving a matching result transmitted by the security device; if the matching result indicates that the program matches the whitelist, executing the program; if the matching result indicates that the program does not match the whitelist, starting a security container and executing the program within the security container. This application can ensure the security of the computer system while avoiding the high false alarm rate of the whitelist mechanism and improving the flexibility of program execution under the whitelist mechanism, thereby achieving program execution while balancing security and flexibility.
