Embodiment 1

[0037] The invention relates to a safe evacuation system for underground caverns. By sensing the real-time distribution of personnel during the evacuation process, the optimal evacuation path is calculated, and based on this, the evacuation guidance device is used to guide the evacuation, so as to improve the efficiency of evacuation and reduce the evacuation time. Casualties and other major losses occurred.

[0038] according to image 3 As can be seen, a kind of underground cavern group safety inspection method based on radio frequency identification (RFID), its steps are:

[0039] 1) Determine the evacuation network A of the underground caverns: establish the building information model (BIM) of the underground caverns, the information model is drawn by AUTODESK REVIT according to the actual three-dimensional layout of the underground caverns, and the evacuation network is abstracted according to the information model, mainly in the The underground cavern passage is used as...

Embodiment 2

[0045] according to figure 1 , figure 2 It can be seen that a safety inspection system for underground caverns based on radio frequency identification (RFID) consists of a computing system 1, a storage system 2, an indicating system 3, an evacuation network system 4, an induction system 5, a lighting indicating device 6, a radio frequency The identification (RFID) position 7 is composed of 7, and its connection relationship is: the storage system 2 is connected with the radio frequency identification (RFID) position 7 and the evacuation network system 4 respectively, and the evacuation network map is stored in the storage system, wherein the nodes of the evacuation network map represent the wireless network. The radio frequency identification (RFID) position 7; the induction system 5 is connected with the storage system 2 and the computing system 1 respectively, the induction system determines the location of the evacuated personnel, and updates the real-time position of the...

Embodiment 3

[0048] according to Figure 4 It can be seen that, a safety inspection method for underground caverns based on radio frequency identification, according to the method of the present invention, the following demonstration experiment is designed. The evacuation road network system of an underground cavern group is as follows: Figure 4 shown, where R i Indicates the gathering place of people in the underground cavern group, and the real-time position of the evacuated people determined by the sensor system, E i Indicates the evacuation exit of underground caverns. Determine the starting position of the evacuated personnel according to the induction system 5, such as Figure 4 R i Indicates that the shortest path of the evacuation scheme is calculated according to the Dijkstra algorithm in computing system 1, and an optimal evacuation scheme is generated for each gathering place, as shown in Table 1.

[0049] Table 1 The shortest path is the target evacuation path set and evacua...

Abstract

The invention discloses an underground cavern group security inspection method and system based on wireless radio frequency recognition. The security inspection method comprises the following steps of(1) establishing an underground cavern building information model, and constructing an underground cavern group dispersing road network system; (2) arranging a wireless radio frequency recognizing and sensing device at each dispersing road network node, and enabling a sensing system to sense real-time position of dispersing staff in a real-time manner; (3) according to the dispersing road networksystem and a wireless radio frequency recognizing and sensing system, determining the real-time position of the dispersing staff, and calculating a dispersing route of the dispersing staff by a calculating system; and (4) according to the shortest dispersing route of the dispersing staff calculated by the calculating system, outputting the shortest dispersing route to an indicating system. A storage system is connected with a wireless radio frequency identification position and a dispersing network system; the sensing system is connected with the storage system and the calculating system; andthe indicating system is connected with the calculating system and an illumination indicating device. The underground cavern group security inspection device is simple in structure, accurate positioning and targeted guiding of the dispersing staff are realized, and the dispersing efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of evacuation and rescue, and more specifically relates to a safety inspection method for underground caverns based on RFID, and also relates to a safe evacuation indication system for underground caverns, which is suitable for the real-time distribution of personnel during the induction evacuation process, The optimal evacuation path is calculated, and based on this, the evacuation guidance device conducts evacuation guidance, which improves the efficiency of evacuation and reduces the evacuation time, avoiding major losses such as casualties. Background technique [0002] The total amount of hydropower projects in my country is large, and there are many large-scale hydropower projects under construction. The underground plant of hydropower projects is the basic building of hydropower projects. It has problems such as large area, poor lighting conditions, and many risk factors, which lead to safety accidents...
