System and method for accelerating MMU mapping table deployment

The invention provides a system and a method for accelerating MMU mapping table deployment. The system comprises an MMU mapping table generation device and a verification program packaging device which run on a verification program compiling server, and an MMU mapping table deployment device which runs on a target SOC; the MMU mapping table generation device is used for reading, analyzing and legality checking an MMU mapping table configuration file, and generating an MMU mapping table adaptive to the target SOC according to the MMU mapping table configuration file; the verification program packaging device analyzes an original verification program generated by compiling, obtains an MMU mapping table address specified by the verification program and maximum size information of an MMU mapping table, checks validity of the size of the MMU mapping table adapted to a target SOC, and combines and packages the generated MMU mapping table adapted to the SOC and the verification program into a new verification program containing the MMU mapping table; and the MMU mapping table deployment device analyzes the MMU mapping table adapted to the target SOC, and completes deployment of the MMU mapping table on the target SOC.

Firewall policy task automatic processing system and method

ActiveCN112787867AAvoid Duplicate Policy ConfigurationTimely communication and processingData switching networksAuto-configurationEngineering
The invention provides a firewall policy task automatic processing system and method, and relates to the technical field of process automation, and the system comprises a request processing module which is used for obtaining a policy task request sent by at least one requester, and when the policy task request is in an approved state, sending the policy task request to the requester, processing the strategy task request to obtain request strategy content contained in the strategy task request; a policy configuration module which is used for comparing the request policy content with the current configuration information of the firewall, and performing firewall policy configuration according to a comparison result to obtain a corresponding configuration result; and a configuration verification module which is used for verifying the configuration result according to the request strategy content to obtain a verification result, and sending the verification result to the requester and at least one corresponding network operation and maintenance person. The method has the beneficial effects that repeated policy configuration can be effectively avoided while automatic configuration of the firewall policy is realized, the configuration error rate of the firewall policy is reduced, and the time for network operation and maintenance personnel to execute repeated work is shortened.

Door configuration system and method

The invention discloses a door sash configuration system. The door sash configuration system comprises a motor and a controller. An angle measurement transducer is installed on the motor. The door sash configuration system further comprises a universal transducer interface and a normalization module. The input end of the universal transducer interface is connected with the angle measurement transducer, and the output end of the universal transducer interface is connected with the normalization module. The normalization module is connected to the controller. The invention further discloses a door sash configuration method. The door sash configuration method includes the following steps that firstly, the system is powered on, the angle measurement transducer measures the angle of the motor, and an angle measurement value is input to the normalization module through the universal transducer interface; secondly, a normalization angle measurement parameter table is searched for a normalization angle measurement value corresponding to the currently acquired angle measurement value through the normalization module, and the found normalization angle measurement value is input to the controller; thirdly, the controller controls the motor to rotate according to the normalization angle measurement value. According to the door sash configuration system and method, calculation cost of the system is saved, and stability of the system and further improvement in the system are facilitated.

Method and terminal for enabling iptables rule to support local time

The invention provides a method and a terminal for enabling an iptables rule to support local time. The method comprises the following steps of: initializing an operating system, and setting time of the operating system and time zone information of the operating system; acquiring the time of the operating system and the time zone information of the operating system in a user mode; configuring thetime zone information of the operating system to a kernel; setting the iptables rule of the firewall, wherein the iptables rule is a rule about expected time control, and the expected time IS set according to a time zone set by the operating system; receiving a message by means of the kernel; converting world unified time UTC in the message into the time in the time zone set by the operating system according to the configured time zone information by means of the kernel; matching the time obtained by conversion with the expected time to obtain a matching result by means of the kernel; and releasing or discarding the message according to the matching result and the iptables rule of the firewall. The method solves many problems in the prior art, greatly simplifies the use difficulty of the iptables firewall based on time control, improves the work efficiency, and reduces the probability of configuration errors.
