The invention provides a battle tracking system and method aiming at firefighters at a fire scene. The system comprises shoe bodies, position labels and a fire fighting commanding system, wherein each shoe body is provided with a micro control unit, a GPS module, an inertial navigation system module, a label identifying module, an environment induction sensing module, an alarming module, a communication module and a power supply in the position of the heel of a sole; the label identifying modules are used for identifying the position labels in a building through scanning and obtaining the three-dimensional absolute coordinate values of the positions where the labels are placed; the shoe bodies are communicated with the fire fighting commanding system for data transfer through the communication modules. The battle tracking system has the benefits as follows: the positioning system is combined with the special shoes of firefighters, so that the real-time position tracking of battle firefighters at the fire scene and the real-time detection monitoring on the fire scene disaster situation can be implemented, and the real-time positions of firefighters and the fire scene disaster situation can be fed back to commanders through the communication modules in time, therefore, the commanders can control the overall situation conveniently, the safety of people's lives and properties can be guaranteed furthest, and the fire damage is reduced.

The invention discloses a method for acquiring traffic information through mobile terminals, belonging to the technical field of communication. The method comprises the following steps: using a network side traffic information extraction server to extract one or more than one mobile terminal in the network as the selected mobile terminal according to preset rules; continuously extracting positioninformation of the selected mobile terminal, and tracking the position of the selected mobile terminal; and determining traffic information of the area of the terminal by using the network side traffic information extraction server according to the motion conditions of the tracked mobile terminal. In such a way, the invention can effectively utilize the 3G network and the mobile terminals in the 3G network to extract the traffic information. Meanwhile, the invention does not need to add a new hardware module to the mobile terminal so as to lower the initial input for traffic information acquisition, and can be used for acquiring accurate traffic information by means of precise positioning and sufficient terminal samples.

The invention discloses an unmanned ship event triggering hierarchical cooperative control system, which comprises a distributed event triggering state observation module, a position tracking control module, a communication network, an unmanned ship and a target ship. The distributed event triggering state observation module is used for monitoring an adjacent unmanned ship in real time, and when the position information of the neighbor ship is updated, triggering the unmanned ship to observe the position and speed information of the target ship, and comprises a first event triggering unit and a distributed observation unit, and the position tracking control module is used for estimating the position, angle and speed tracking error of the target ship and triggering the unmanned ship to track the target ship. The the position tracking control module comprises a tracking control unit, a third event triggering unit and a reduced-order distributed observation unit, the distributed observation unit and the tracking control unit are designed in a layered mode, independence of all layers is achieved, through cooperation of all the layers, the complexity of the multi-unmanned-ship target tracking problem is effectively reduced, and the expansibility of the multi-unmanned-ship target tracking control system is improved.
