In the aspect of monitoring accuracy, the activity density of people is accurately detected based on a human body infrared sensor and the like, and equipment parameters are adjusted in combination with multiple factors, so that the monitoring equipment adapts to different scenes, accurate information is provided for security, management and the like, and scientific decision making is assisted.

An access control system includes a bolt configured to be fixed to an interior part of a housing, a latch configured to engage the bolt when the bolt is fixed to the housing, and an access door to the housing that is in the closed position. The access control system is configured to detect, using one or more sensors, when the latch is within a predetermined proximity of the bolt, and in response to the detection that the latch is not within the predetermined proximity of the bolt, determine whether an authorized credential was received through a communication interface to open the latch, and when the authorized credential was received, record an authorized opening of the latch to a memory device, and when the authorized credential was not received, record an unauthorized opening of the latch to the memory device and enter an alert state.

The invention provides an operation method of a warehouse access control system. The method includes: touring a plurality of images captured by a plurality of monitors; judging the biological characteristics of the unverified person and generating a judgment result; switching the state of the warehouse based on the judgment result; judging the state of the warehouse; detecting an image captured by the monitor; detecting whether any human is in the image captured by the monitor; if there is a human being in at least one of the images captured by the monitor and if the warehouse is in an alert state, an alert is given. Generally speaking, the warehouse access control system and the operation method thereof provided by the invention not only improve the safety of the warehouse, but also prevent suspicious persons from stealing properties in the warehouse.

A prompt information display method is performed by a computer device. The method includes: displaying a picture of a virtual environment, and the virtual environment comprising the first virtual object and at least one second virtual object; and updating the virtual environment picture with alert prompt information of the second virtual object for the first virtual object, the alert prompt information being configured for indicating an alert state type and an alert state progress of the second virtual object, the alert state progress being configured for controlling switching between different alert state types indicating different reactions of the second virtual object to the first virtual object. The foregoing method can enable a user to quickly obtain and learn a state change of a virtual object, thereby improving information obtaining efficiency, and further improving human-computer interaction efficiency.

A guidance device for a vertical takeoff and landing aircraft includes: a detection unit that acquires the location of each aircraft in a control area; a guidance route setting unit; a virtual exclusive area setting unit that sets a virtual exclusive area around each aircraft; a control area state management unit; and a communication unit. When a distance between virtual exclusive areas is less than or equal to a warning state threshold, the state of the control area is set to an alert state, and warning information is transmitted. When the virtual exclusive areas overlap with each other, or when the distance therebetween is less than or equal to an emergency state threshold, the state of the control area is set to an emergency state, and the communication unit transmits, to an aircraft deviating largely from the guidance route, information indicating that the aircraft is designated as an uncontrolled aircraft.

The invention provides an optimization method and device for memory overflow of a springboard machine, equipment and a medium, the springboard machine comprises two TCP connections for parallel data copying, and the optimization method comprises the following steps: establishing an observer monitoring mechanism between the two TCP connections for parallel data copying; the observer monitors a data reading event of two TCP connections; when it is detected that connection of any end completes data transmission, the observer enters a warning state; and in the warning state, if the surviving TCP connection does not read the data within the preset timeout time, the observer actively closes the corresponding two TCP connections, and the idle connection is timely closed through a monitoring mechanism, so that the connection resource accumulation is prevented, the normal operation of the springboard machine on the server is ensured, and the user experience feeling is good.

The invention discloses a multi-parameter combined early warning method and system for landslide disasters, particularly relates to the technical field of landslide monitoring and early warning, and is used for solving the problem that the early warning accuracy and reliability are insufficient due to the fact that an existing early warning method is difficult to effectively fuse deep resistivity and geomagnetic field abnormal information directly related to a landslide instability mechanism. The method comprises the following steps: firstly, synchronously acquiring earth surface displacement, rock-soil mass mechanical and hydrological triggering, resistivity and geomagnetic field data, judging an early warning ring state based on the earth surface displacement and the triggering data, and when entering the early warning ring state, analyzing distribution evolution characteristics of the resistivity and the geomagnetic field data in a landslide mass space range; according to the method, parameters representing spatial focusing performance of each abnormal area are extracted, then a resistivity and geomagnetic field spatial collaborative focusing signal triggered by a landslide mass internal damage accumulation or sliding surface forming process is identified, and finally, a combined early warning instruction is generated according to the intensity and the continuous range of the signal in combination with the grade of an early warning ring state.
