Embodiment
As shown in Figure 1, a kind of ancient building Environmental Protection System based on wireless sensor network, comprises wireless sensor network, wireless communication module and remote monitoring and controlling system.Be distributed in the various kinds of sensors node inside and outside ancient building and aggregation node composition wireless sensor network.As shown in Figure 2, sensor node place is provided with processor module, sensor assembly, wireless communication module and power module, the processor module at sensor node place is connected with power module with the sensor assembly at sensor node place, wireless communication module respectively, controls other modules work.Aggregation node place is also provided with aggregation node processor module, aggregation node communication module and aggregation node power module, and aggregation node processor module is connected with aggregation node power module with aggregation node communication module respectively.The present invention, in order to reduce power consumption as far as possible, extends service time of battery, and wireless sensor network adopts LEACH Routing Protocol.
Sensor node comprise be arranged on ancient building indoor temperature sensor, humidity sensor, photosensitive sensor, heat sensitive sensor, control flow of the people inductor etc., be arranged on shockproof, theft-proof sensor outside ancient building etc., for measuring different environmental coefficients.Processor module is the nucleus module at sensor node place, for performing instruction, carrying out treatment and analysis to sampled data.Sensor assembly is connected with processor module, power module respectively.For ancient building internal and external environment data of sampling, and give processor module by sampling data transmitting.
Wireless sensor network adopts LEACH Routing Protocol, and cluster head random-selection node in a circulating manner, is evenly distributed to the energy load of whole network in each sensor node, thus reaches the energy resource consumption of reduction network, raising overall network life span.
As shown in Figure 3, described leader cluster node manages a bunch inner sensor node and will carry out data fusion.The LEACH continuous restructuring procedure to perform bunch of circulation in operational process, each bunch of restructuring procedure can describe by the concept of bout.Each bout can be divided into two stages: bunch establishment stage and transmission data stabilization sub stage.Bunch process of establishing can be divided into 4 stages: the selection of leader cluster node, the broadcast of leader cluster node, the foundation of leader cluster node and the generation of scheduling mechanism.
The number of times that leader cluster node sum required in the selection gist network of leader cluster node and up to now each node have become leader cluster node decides.Concrete selection way is: a value between each sensor node Stochastic choice 0-1.If selected value is less than some threshold values, so this node becomes leader cluster node.
After selected leader cluster node, inform whole network by broadcast.
Other nodes in network according to the signal intensity of the information of reception determine subordinate bunch, and notify corresponding leader cluster node, the foundation to complete bunch.
Leader cluster node adopt TDMA mode be bunch in each peer distribution transmit the time point of data to it.
In stabilization sub stage, the data of collection are sent to leader cluster node by sensor node.Leader cluster node to bunch in the data that gather of all nodes carry out information fusion after send aggregation node to again, this is a kind of reasonable working model of less message volume.After stabilization sub stage continues for some time, the establishment stage that network reenters bunch, carries out bunch reconstruct of second leg, constantly circulates, and each bunch adopts different CDMA codes to carry out the interference communicating to reduce other bunch of interior nodes.
Aggregation node is set up communication by communication and sensor node and is connected, receive to sensor node and send data, sensor node receives the control command of aggregation node transmission by wireless communication module, and control command is transferred to processor module treatment and analysis; Sensor node, by the environmental parameter of wireless communication module by sampling, is sent to aggregation node sensor node, by multi-hop relay mode, Monitoring Data is transferred to aggregation node.Aggregation node by wireless communication module, is connected to Internet network and monitor with Long-distance Control and connect, rearward monitor supervision platform reception and transmission data.
Remote monitoring and controlling system, is made up of PC, ancient building environmental parameter storehouse and warning system, PC is provided with the watchdog routine of writing by C language.System is by the data analysis process of long-range sampling; show with graphic interface, and data are backed up, when data in the data just obtained and storehouse carry out trigger alarm device when exception appears in contrast; staff is reminded to note, to take necessary protection.
The ancient building environmental structure health of multiple monitored area is responsible in a monitoring station, an aggregation node is settled in each monitored area, data are sent to aggregation node by LEACH Routing Protocol by the data of collection by sensor node, aggregation node by simple data processing again by valid data timely by wireless communication module long-range send to Internet, remote monitoring center just can monitor required data, and observing environment conversion at any time.The present invention effectively can overcome the shortcoming of traditional structure health monitoring systems, wireless sensor node is arranged on the key position of buildings, the structural health conditions of Real-Time Monitoring buildings, finds early and locates buildings damage, reducing unnecessary personnel's economic loss.
