Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of earthquake emergency management, and particularly relates to a MATLAB-based earthquake evacuation emergency resource allocation management platform. BACKGROUND

[0002] The MATLAB-based earthquake evacuation emergency resource allocation management platform is a scientific decision support system developed by using a MATLAB programming environment and related toolboxes, and aims to solve the problems of emergency resource allocation and evacuation management after an earthquake disaster by mathematical modeling, optimization algorithms and visualization technology.

[0003] The core goals of the platform are as follows:

[0004] Optimized resource allocation: under the condition of limited resources (such as medical supplies, rescue teams, shelter capacity, etc.), the optimal allocation scheme is quickly calculated;

[0005] Evacuation path planning: providing safe and efficient shortest evacuation paths for disaster-affected people;

[0006] Dynamic decision support: dynamically adjusting strategies according to real-time disaster data (such as aftershocks, road damage);

[0007] In the process of building the above platform, a large amount of earthquake information needs to be collected, including a seismic intensity sensor, which monitors the magnitude, focal depth and ground acceleration (P / S wave detection) in real time, and is used to trigger emergency response. However, the traditional seismic intensity sensor lacks a related clamping fixing structure, which causes it to be easily disturbed by external interference, such as collapsed buildings, during the monitoring of seismic intensity in the earthquake site, thereby causing large errors in the monitored related data and affecting the earthquake evacuation emergency resource allocation of the platform. SUMMARY

[0031] The present application will be further described below in conjunction with the embodiments.

[0032] Embodiment 1:

[0033] Reference Figures 1-4 ​For the first embodiment of the application, a MATLAB-based earthquake evacuation emergency resource allocation management platform is disclosed, comprising a background data center 1 and a plurality of sensors 2 connected to the background data center 1, further comprising a support seat 4 fixedly installed on both sides of the plurality of sensors 2, two clamping plates 41 are arranged on the side of the two support seats 4 facing each other, two telescopic rods 42 are vertically and fixedly installed on the side of the two clamping plates 41 away from each other, springs 43 are installed between the corresponding support seat 4 and the distal end of the four telescopic rods 42, and the two clamping plates 41 are connected to the main pull rope 44 on the distal end away from each other, the rotating assembly comprises a gear 31 rotatably installed on the top of the sensor 2, two L-shaped racks 32 are meshingly installed on both sides of the gear 31, and the distal end of the two L-shaped racks 32 is connected to the auxiliary pull rope 34, and the end of the two auxiliary pull ropes 34 is connected to the corresponding main pull rope 44.

[0034] Embodiment 2

[0035] Reference Figures 1-4 For the second embodiment of the application, the difference between this embodiment and the first embodiment is that the top of the sensor 2 is provided with an installation cavity, the gear 32 is rotatably installed in the installation cavity, the upper cavity opening of the installation cavity is fixedly installed with a cover plate, the top center of the gear 32 is vertically fixedly installed with a knob 33, the knob 33 is arranged above the cover plate, the top of the two L-shaped racks 32 is fixedly installed with a limiting block, and the lower bottom of the cover plate is provided with a limiting groove for facilitating the reciprocating sliding of the limiting block.

[0036] The two support seats 4 are internally provided with installation cavities, and the top of the two support seats 4 is provided with an opening penetrating the installation cavity, the upper cavity opening of the opening is rotatably installed with a first fixed pulley, the installation cavity is rotatably installed with a second fixed pulley, the distal end of the two auxiliary pull ropes 34 is respectively wound around the corresponding first fixed pulley, and the corresponding installation cavity is penetrated from the corresponding opening, and is fixedly connected with the corresponding main pull rope 44, and the two main pull ropes 44 are respectively wound around the corresponding second fixed pulley and fixedly connected with the corresponding clamping plate 41.

[0037] The rest of the structure is the same as that of embodiment 1.

[0038] The working process of the application is as follows:

[0039] First, rotate the knob 33, and then drive the gear 31 to rotate, so as to meshingly drive the two L-shaped racks 32 to move in the direction of approaching each other, so as to respectively pull the corresponding auxiliary pull rope 34 and the main pull rope 44, and finally pull the corresponding clamping plate 41 to fit the corresponding support seat 4 more closely, so that the distance between the two clamping plates 41 is increased, and the two springs 43 on the side of the two clamping plates 41 away from each other are forced to compress, so as to obtain the elastic recovery force.

[0040] Secondly, place the sensor 2 on the appropriate surface of the placed object, and loosen the knob 33. Through the elastic reset of the two springs 43, the corresponding clamping plates 41 are pushed to move towards each other, and finally are extruded and fitted on both sides of the placed object, thereby completing the temporary fixation of the sensor 2 and the placed object;

[0042] The earthquake intensity sensor (such as MEMS accelerometer) outputs real-time data through RS-485 / Modbus or IoT wireless module (LoRa / NB-IoT), and the serialport or tcpclient object directly reads the serial / network data stream. The MATLAB signal processing toolbox (lowpass, waveletDenoise) calculates the intensity: converts the acceleration data into modified Mercalli intensity (MMI);

[0049] Evacuation demand: the higher the intensity → the more estimated casualties (grey prediction model);

[0050] Road passability: relationship between intensity and road damage probability (Monte Carlo simulation);

[0051] Optimization model solution

[0052] Use mixed integer linear programming (MILP) or genetic algorithm (GA) to dynamically allocate resources;

[0053] Output instruction type

[0056] Control signals are generated by MATLAB to drive the following devices:

[0057] Electronic sign: update evacuation direction (through GPIO or HTTP instruction);

[0058] Drone scheduling: send waypoint coordinates to the flight control system (MAVLink protocol).
