Construction tunnel safety protection method based on wireless sensor network and a monitoring system thereof

Abstract

The invention belongs to the field of construction safety monitoring and wireless communication and discloses a construction tunnel safety protection method based on a wireless sensor network and a monitoring system thereof. The method is as follows: by acquiring environment, work amount and locating data of personnel in a tunnel, realizing alarming services of six types of dangerous situations and corresponding safety protection means, calling a protection plan to take protection measures on key parts of the system when emergent (dangerous) events occur, and with the purpose of guaranteeing personal safety, releasing a control command. The system comprises a wireless sensor network based on industrial wireless communication standard WIA-PA, a positioning network and a mobile network. If the dangerous situation develops further, the system exchanges data with a remote mobile server by a 3G network, leads a community security system into the range of a construction tunnel safety protection system, and provides united rescue of communities and disaster control services. The invention is used for tunnel construction safety monitoring, and a computer or 3G mobile equipment can obtain construction site information at any time; and the installation of the WIA-PA wireless network is flexible, and the formed safety protection system and sensing early-warning network make contribution to solving the problem of tunnel safety construction fundamentally.

Description

technical field [0001] The invention relates to the field of tunnel construction safety monitoring and wireless communication, in particular to a sensor network-based tunnel safety protection method and monitoring system. Background technique [0002] With the rapid development of my country's economy, the number of tunnel construction projects is increasing day by day, and the problems of tunnel construction safety and tunnel safety operation are becoming more and more prominent. Tunnel construction safety is a complex system engineering, any link in the middle may lead to huge accidents if not done well. [0003] At present, with the progress of construction, the amount of monitored environment will continue to increase. There will be disadvantages if the wired monitoring method is used: 1) the wiring will be very complicated, which will increase the difficulty of construction, and the variety of lines in the tunnel will increase the possibility of accidents; 2) the wired...
