Site potential safety hazard control Markov network analysis system

Abstract

The invention provides a site potential safety hazard control Markov network analysis system which comprises a mobile terminal and a cloud server, the mobile terminal comprises a positioning and navigation module used for acquiring geographic position information and providing a navigation function; an identification module used for carrying out identity identification on the construction site potential hazard object to be acquired; a data acquisition module used for carrying out data acquisition on each characteristic sample of the site potential hazard object; a data submitting module used for submitting the acquired characteristic sample data to the cloud server; the cloud server comprises a matrix management module used for establishing a Markov potential hazard analysis matrix for each control object on the site based on the prior knowledge, and a network model management module used for generating a Markov potential hazard analysis network model according to the Markov potentialhazard analysis matrix to carry out the network traversing and calculation on the risk state of each facility on the site. According to the invention, the accident risk caused by the potential hazardof the site can be accurately evaluated, and the required cost is low.

Description

technical field [0001] The invention relates to the technical field of construction site safety hazard management, in particular to a Markov network analysis system for construction site safety hazard management and control. Background technique [0002] In the application field of construction site safety hazard analysis, it is necessary to analyze the construction site safety hazards and carry out early warning analysis of safety hazards in the construction process, so as to identify key safety factors that may cause safety accidents, and facilitate the construction site. Control. [0003] The current related technologies mainly include the following: [0004] The patent with the publication number CN205540184U discloses a construction site safety monitoring and management system, which discloses a construction site monitoring unit and a monitoring management terminal, wherein the data processor of the construction site monitoring unit is connected to the construction sit...

Problems solved by technology

Then connect to the background server through the communication server. The background server has both printing and sound and light alarm effects, but its disadvantage is that it only alarms when a single element exceeds the threshold.

[0005] The patent with the publication number CN204887033U discloses a central office device that can collect the information of supervisors. This technology designs a central office device for the attendance statistics of construction site supervisors, which is convenient for the company to manage and dispatch supervisors. , but its shortcoming is that it only focuses on the management and scheduling of supervisors, and does not involve the management and control of hidden dangers on the construction site.

[0006] The patent with the publication number of CN101521805A discloses a construction site helmet on-site detection system and method. This technology designs a video algorithm to check whether workers have put on the helmet. This technology involves personnel safety, but is limited to Detection of whether the helmet has been worn

[0007] The patent with the publication number CN204679777U discloses a construction site safety information collector. This technology designs a device for collecting tower crane operation information and dust emission information. The disadvantage is that this method is limited to tower crane operation information. collection and collection of dust

[0009] The patent with the publication number TW201334721A discloses a construction site helmet that combines physiological and activity signals. This technology designs a helmet with a communication function, but its disadvantage is that it is only used to monitor the fatigue state of workers

That is to say, the current related technologies have relatively large functional limitations, and cannot realize big data analysis on the management and control of construction site safety hazards, early warning analysis of safety hazards in the construction process, and key safety issues that may lead to safety accidents. elements to discriminate
