Abstract

The invention provides a control method and a system for an accident rescue deduction terminal, and relates to the technical field of accident rescue deduction terminal control. The method comprises the steps of receiving an urgent treatment plan sent by a server through an independent priority communication channel, forcedly suspending a low-priority interface rendering task currently executed by a main rendering thread when the urgent treatment plan is received, preferentially displaying the urgent treatment plan on the top layer of a screen through a preset simplified interface, providing an operation confirmation button decoupled from the main rendering thread through the simplified interface, generating a confirmation instruction when the operation confirmation button is triggered, and sending the confirmation instruction to an AR device of a rescue unit through the priority communication channel so as to drive the AR device to execute a recommended treatment plan. The method aims to solve the problem that system resources are tense and command terminal interfaces are blocked due to sudden environmental changes, so that a commander is influenced to rapidly issue key instructions, and immediate response and execution of the instructions are ensured.

Description

Accident rescue deduction terminal control method and system Technical Field The invention relates to the technical field of accident rescue deduction terminal control, in particular to an accident rescue deduction terminal control method and system. Background In the field of modern emergency management and training, in order to improve the capability of coping with emergencies, in particular to complex and high-risk environments such as ports, an advanced simulation deduction system is introduced. These systems typically incorporate a variety of front-end technologies, such as Augmented Reality (AR) technology, which can superimpose virtual information into the real world, allowing trained personnel to obtain an immersive experience, geographic Information Systems (GISs) providing accurate geospatial data and situational displays, and intelligent reckoning mechanisms that can simulate the process of accident development, plus a communication platform that ensures real-time transfer of information. The combination of these techniques aims to provide a highly realistic training environment for rescue workers, thereby effectively improving their actual combat command and operational capabilities. However, in practical applications, such systems, when faced with extreme, abrupt and rapidly changing complex scenarios, may be severely challenged by the response capability of their control terminals and the fluency of human-machine interaction, thereby affecting the effectiveness of the training. When external environmental factors (such as wind direction and wind speed) change drastically, the accident evolution calculation model needs to be calculated again intensively, and the GIS interface is driven to perform large-scale and high-complexity graphic rendering so as to display the dynamic change of the accident situation (such as dangerous gas diffusion cloud cluster) in real time and realistically. This process can momentarily take up a significant amount of processor and graphics processing resources of the control terminal. However, existing control methods fail to effectively prioritize and manage resources for different tasks, resulting in a system that devotes a vast majority of resources to background simulation computations and foreground situation visualization rendering. The resource allocation strategy reduces the priority of the interactive interface for responding to the operation of the user, thereby causing the phenomena of interface response delay, inaccurate touch input and even no response. This results in that at the most critical moment of the accident development, when the commander needs to immediately redeploy rescue forces or plan an evacuation route through operations of clicking, dragging, etc., the operation instructions thereof cannot be timely and accurately received and executed by the system. Finally, the system sacrifices the instantaneity and the effectiveness of command control while pursuing the authenticity of situation presentation, so that a commander cannot effectively intervene when facing emergency conditions, and the original purpose of deducting the system for improving the emergency command capability is fundamentally overcome. Disclosure of Invention The invention aims to provide an accident rescue deduction terminal control method and system, which aim to solve the problems that in port accident rescue deduction, when sudden environmental changes cause system resources to be tense and command terminal interfaces to be blocked, a commander is influenced to rapidly issue key instructions, when the system detects emergency threat, a preset emergency disposal scheme is actively generated and pushed, and the operation of the commander is simplified into one-key confirmation, so that the instant response and execution of the instructions are ensured. In a first aspect, the present invention provides a control method for an accident rescue deduction terminal, including the following steps: s1, receiving an emergency treatment plan sent by a server through an independent priority communication channel, wherein the emergency treatment plan comprises a recommended treatment plan generated for a rescue unit determined to face emergency threat; s2, when an urgent treatment plan is received, forcibly suspending a low-priority interface rendering task currently executed by the main rendering thread, and preferentially displaying the urgent treatment plan on the top layer of a screen through a preset simplified interface; And S3, when the confirmation button is triggered, generating a confirmation instruction, and sending the confirmation instruction to the AR equipment of the rescue unit through the priority communication channel so as to drive the AR equipment to execute the recommended treatment scheme. According to the accident rescue deduction terminal control method provided by the invention, in port accident rescue deduction, when the system detects the emergency threat c
