Embodiment
Below in conjunction with accompanying drawing, the present invention is described in further details.
The object of the invention is to design a kind of large regions supervisory system integrating oscillatory type energy collecting device, energy-storage travelling wave tube, signal launching and receiving equipment.This system is used for the auxiliary monitoring of oversize vehicle in region, to a certain degree can greatly strengthen security protection ability.
The object of the present invention is achieved like this:
Designed monitor network is primarily of multiple node, several points of base stations, a dominant base and a computing machine composition.Node is the part of whole monitor network core the most, its involving vibrations formula energy collecting device, energy-storage travelling wave tube and sender unit, is responsible for monitoring and the output of signal; Point base station connects several node, and it is responsible for the signalman that receiving node sends and it is again exported, and plays transfer effect; Dominant base is connected with all points of base stations, is responsible for receiving and integrating all signals, and transmits it to computing machine; The analysis and treament of signal is completed by computing machine, and last monitoring situation just can intuitively show on computers.
Energy collecting system designed by the present invention is oscillatory type electromagnetic energy gathering-device.Designed oscillatory type energy collecting device is primarily of three blocks of magnet and coil composition.Wherein two pieces of fixed magnets are fixed on upper and lower end parts, and to be that polarity is contrary install and can freely activity for middle moving magnet and upper and lower fixed magnet.When being subject to extraneous vibration, the meeting of reciprocating vibration of moving magnet produces induction current in coil, is stored among energy-storage travelling wave tube finally by voltage doubling rectifing circuit, reaches the object of collection of energy.
Composition graphs 1 ~ 5, the present invention devises a kind of self-powered border supervisory system.Its monitor network is designed to tree-network topology structure, has the advantages such as structure is simple, cost is low, nodes expansion is convenient, flexible, searching link paths is more convenient.
Fig. 1 is monitor network schematic diagram of the present invention.Node can be collected vibration signal and store energy of vibration, and generally, the energy harvester in node can be collected extraneous micro-vibration and is stored among energy-storage travelling wave tube.When oversize vehicle passes through, vibration signal reaches monitoring critical value, and sender unit sends invasion signal, realizes the first step of monitoring.Because wireless transmission distance is limited, therefore point base station set up essential.Point base station receives and identifies the signal from leaf node, subsequently respective signal is emitted to base station, the transfer of settling signal.Base station is the root of tree-network topology structure, and it receives and arranges the signal from all points of base stations, is connected with computing machine.Computing machine primary responsibility signal transacting, by display, the monitoring situation of node coverage areas can have a simple and clear displaying.
