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

InactiveCN102042030AOvercome problemsChange the situation of "only monitoring but not monitoring"Mining devicesNetwork topologiesSecurity systemServer
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.

Mobile robot path planning method used in intensive storage zone

ActiveCN102830702AReduce time spentSolve the problem of safety collision avoidancePosition/course control in two dimensionsDynamic planningSimulation
The invention relates to a mobile robot path planning method used in an intensive storage zone. The mobile robot path planning method is technically characterized by comprising the following steps: step 1, an initialized net type path diagram is set up by a scheduling layer server; step 2, a cargo storage task is divided into an empty trunk cargo searching subtask and a loading delivering subtask by the scheduling layer server; step 3, a dynamic planning path of the mobile robot is established by the scheduling layer server and a dynamic planning path of the mobile robot is sent to the mobile server; step 4: the mobile robot executes the corresponding subtask; step 5: the mobile robot sends a state report of the mobile robot to the scheduling layer server; and step 6, the scheduling layer server updates the current position, the load state, and a weight related to an original starting point and a target point of the mobile robot. By dividing every task into the empty trunk cargo searching subtask and the loading delivering subtask, according to the planning paths of different subtasks, the complexity of a safety collision prevention operation of a plurality of mobile robots is reduced, and the instantaneity and the effectiveness of the system are improved.
