This application discloses a security protection method and related products. The method includes: identifying abnormal behavior in the data to be processed corresponding to a target vehicle based on a preset security rule base and a pre-trained anomaly recognition model to obtain a security recognition result; if the security recognition result indicates a first anomaly level, then performing local security protection on the target vehicle according to a local protection strategy; if the security recognition result indicates a second anomaly level, then obtaining the collaborative protection strategy sent by the cloud platform corresponding to the target vehicle, and performing collaborative security protection with other vehicles according to the collaborative protection strategy. This improves the security of the entire vehicle-to-everything (V2X) environment.

This invention relates to the field of automated copper billet casting technology, and particularly to a method and system for controlling the drawing of copper billets based on temperature monitoring. The method includes: real-time acquisition of temperature data sequences from heat exchange monitoring points in each cooling mold; elimination of measurement drift caused by high-temperature moisture environment based on dynamic baseline calibration; generation of a primary abnormal signal for any cooling mold when the temperature at a single point exceeds a preset safety threshold and the duration reaches a first critical time threshold; statistical analysis of the production number and quantity of the abnormal cooling molds based on the distribution of the primary abnormal signals during the drawing process; generation of a secondary linkage control signal based on the production number if the number of primary abnormal signals in a single cooling mold is multiple or exceeds a preset proportion; and sending an emergency stop control signal to the traction machine in response to the secondary linkage control signal. This invention effectively solves the risk of copper billet quality defects and equipment damage caused by temperature runaway.

The utility model belongs to the technical field of network security protection, and particularly relates to an automatic network disconnection device for computer network security protection, which comprises a software mainboard, a bastion host linkage network disconnection module electrically installed at the top of the software mainboard, an anti-DDoS system module electrically installed on one side of the bastion host linkage network disconnection module, and an anti-DDoS system module electrically installed on the other side of the software mainboard. The bottom of the software mainboard is fixedly provided with a hardware mainboard, the top of the hardware mainboard is electrically provided with a PCI slot, a bastion host is linked with a network disconnection module to terminate a session and isolate a server during abnormal login, and then an anti-DDoS system module is utilized to enable the quantity to exceed a threshold value to automatically switch and clean nodes. According to the method, the server can be isolated when the computer network logs in abnormally, so that the security protection efficiency of the computer network is improved, then the RJ-45 interface is controlled to be switched on and off through the PCI slot, then physical isolation of the internal network and the external network is achieved through the partition card, the computer network can be quickly and physically blocked, and thus the security of computer network protection is improved.

This application relates to a data encryption method, a risky data processing method, an apparatus, a computer device, and a storage medium. The method includes: acquiring application source code data; compiling the application source code data to obtain first application compiled data; replacing the signature encryption public key in the first application compiled data with a simulated public key to obtain second application compiled data. If a data encryption request is received, the method acquires the data to be processed corresponding to the data encryption request, restores the second application compiled data to the first application compiled data, and performs encryption and signature processing on the data to be processed based on the signature encryption public key in the first application compiled data to obtain encrypted signature data. This method can reduce the risk of leakage of the signature encryption public key, as well as information leakage and resource loss to the platform and users, and improve the efficiency of information security protection.

The utility model discloses a protective device for a photovoltaic inverter, which comprises a protective shell and a plurality of protective plates, and the plurality of protective plates are respectively clamped and mounted on two sides, the rear end and the top of the protective shell and are used for safety protection of a photovoltaic inverter body in the protective shell. The front end of the protection plate is provided with a plurality of fin plates, and the plurality of fin plates are arranged in parallel and at intervals, and are used for increasing the contact area between the protection plate and hot air emitted by a photovoltaic inverter body installed in the protection housing. A plurality of fin plates are arranged on the inner side of each protection plate, so that the contact area between the protection plates and hot air emitted by a photovoltaic inverter body installed in the protection shell is increased through the plurality of fin plates, and water cooling liquid output by a water cooling mechanism fully dissipates heat of high temperature generated by operation of the photovoltaic inverter body. And the operation efficiency of the photovoltaic inverter is improved.
