A multi-configuration portable electronic device including a first body, a second body, a dual-axis hinge and at least a guiding module is provided. The dual-axis hinge has a first axis pivotally coupled to the first body and a second axis pivotally coupled to the second body. The guiding module prevents the first axis and the second axis from acting simultaneously. The guiding module includes a track disposed in the first body and a slide connected with the second body. The slide has an interaction force with the track so that the slide can move from the second body to couple with the track.

The invention discloses an electromagnetic door lock of electrical equipment. The electromagnetic door lock comprises a slider block device, a starter, a mechanical sensor and a mechanical linkage device, wherein the slider block devices is moved to a closing position along with shutoff of a door of the electrical equipment, the starter is used for providing power for switching on and switching off a switch device, the mechanical sensor is used for determining the closing position of the slider block device (20), when the slider block device is not located at the closing position, the starter is locked by the mechanical linkage device, and when the slider block device is located at the closing position, the starter is released by the mechanical linkage device, so that the switch device is located at a switch-on position. The mechanical sensor and the mechanical linkage device not only control the electromagnetic door gate in use of the electrical equipment, but lock movable components in the electromagnetic door gate in a transportation process so as to prevent the movable components from playing in the transportation process, and avoid from causing the components of the electromagnetic door lock in an abnormal state.

The invention, which relates to the technical field of industrial control, provides a method and device for detecting an abnormal attack. The method comprises the following steps that: device data ofan industrial device are obtained, wherein the device data are used for expressing the state of the industrial device within a preset period of time; the device data are inputted into an attack detection model to obtain a detection result, wherein the detection result is obtained by analyzing the device data by the attack detection model based on historical device data of the industrial device; and according to the detection result, whether the industrial device is under an abnormal attack is determined. According to the invention, the attack detection model analyzes the current device data ofthe industrial device based on the historical device data of the industrial device, whether the industrial device is under an abnormal attack is determined, and the long-time running state of the industrial device in future is predicted, so that a problem that the user can not take corresponding measures based on the predicted abnormal state because the industrial device is predicted to will havean abnormal state within short time is solved; the time length of prediction by the terminal is prolonged; and the real-time performance of the abnormal attack detection by the terminal is improved.

A battery protection system applicable to an electronic device includes a battery, a control module, a message generating module and an input interface. The control module is electrically connected to the battery for detecting if the battery is in an abnormal state. The message generating module is electrically connected to the control module for generating a battery-error warning message when the control module detects that the battery is in the abnormal state. The input interface is electrically connected to the control module for transmitting a user command to the control module after the battery-error warning message is generated, thereby enabling the control module to release the abnormal state of the battery according to the user command. A battery protection method is also provided.
