Said WSN router is responsible for the wireless data frame routing forwarding.According to this system's actual application environment and scope, an amount of WSN router is set up the WSN backbone network, is responsible for the data interaction between WSN telegon and the WSN collector.The WSN backbone network of being set up by the WSN router covers all the WSN collectors in this subnet, and the communication link from maintenance, selfreparing is provided.
Said WSN collector is battery-powered, is responsible for the data acquisition of connected various kinds of sensors and uploads, is responsible for this monitoring point sensing data analysis and the alarm condition indication.The WSN collector adopts the low power dissipation design scheme, is responsible for field data and collects, and each collector has a plurality of data acquisition channels, can connect a plurality of transducers.And support two big types of transducers simultaneously: a kind of is type vibration wire interface sensor (comprising stress, displacement, counter-force meter, interstitial hydraulic pressure meter, earth pressure gauge etc.); Another kind is the analog quantity interface sensor, mainly comprises (temperature sensor, humidity sensor).
The WSN collector is as shown in Figure 7 to the flow process of sensor data acquisition, and the flow process that the WSN collector is gathered voltage data is as shown in Figure 8, and the WSN collector is as shown in Figure 9 to the flow process of temperature data acquisition.
A kind of building engineering structure safe construction real-time monitoring system comprises the radio sensing network of data-oriented acquisition tasks, and implementation step is following:
The WSN telegon distributes a unique time slot at the first time of all WSN router and the WSN collector is all identical treats during building network in a system cycle of acquiescence;
To the user visual operation-interface is provided, treat that networks are completed after, the difference of the transducer that connects according to collector defines different acquisition tasks, can set the collection period of different task; Or the collector that will connect different sensors is defined as a task groups, can define a plurality of task groups simultaneously, then to cycle of its data acquisition of individual task settings, and the operating time section through visual each task of interface setting;
After the WSN telegon gets access to the parameter of all above-mentioned nodes; Start the time slot allocation mechanism of oriented mission; At first calculate the system cycle of a broad sense according to the cycle parameter value of different task; This system cycle satisfies the collection demand of different task, the collector work that in this system cycle, has once, the collector work that has is repeatedly;
The said new system cycle that calculates also only is kept in the WSN telegon, the default system cycling when adding all nodes in the network still according to initial adding network.At ensuing former default system in the cycle; Each collector all will be communicated by letter once with telegon; Telegon can pass to each collector in the network to parameters such as the system cycle that recomputated, the time slot that belongs to this node, effective time sections; Collector will be transformed into activity pattern from resting state according to the parameter that receives in one's own time slot, accomplish data acquisition and communication work.WSN telegon, WSN router are also preserved the all-network parameter of its child node simultaneously;
In the network operation stage, WSN telegon, WSN router and WSN collector all can carry out network according to the network parameter of preserving separately about father node, child node and connect and the maintenance of breaking off.
In the radio sensing network performing step of data-oriented acquisition tasks:
The division of said data acquisition task, the network parameter of different task are arranged on the WEB server at data monitoring management center and accomplish, and parameter sends to the WSN telegon through ether (3G or GPRS) network after being provided with and accomplishing;
The time slot of said data-oriented acquisition tasks is redistributed by WSN telegon application layer and is realized;
The network of described data-oriented acquisition tasks is set up, network operation is accomplished by the network layer of WSN telegon, WSN router and WSN collector
Described data acquisition task is accomplished by the application layer of WSN collector;
The real-time security monitoring system of a kind of building engineering structure also comprises the data monitoring management platform that customization building-site threedimensional model is provided, and mainly comprises 4 modules: generation module, configuration module, memory module, display module.
Generation module, the default action interface that system at first can provide according to system generates the threedimensional model of an acquiescence.
Configuration module, according to situation on the spot, the user can pass through patterned configuration interface, and relevant parameter is set, and is used for the displaying in later stage with this.
Memory module is used to preserve user configured parameter, so that for different users, can customize targetedly, is user-friendly to.
Display module, according to user's setting, loading configuration file is showed the Information Monitoring of three-dimensional job location.
Implementation step is following:
The Flash control that exploitation has special function.Flash loads the picture of building-site, through reading the XML file of configuration, dynamically generates the nodes such as telegon, router and collector in the threedimensional model, and is as shown in Figure 4.
Load Flash by foreground Web.The user can get into configuration status through clicking Design Mode, and then, Flash obtains all on-the-spot parameters through calling WebService, resolves the XML file that generates, and loads Flash by the page.After the user selects node corresponding, can freely be dragged to any position (this position can be placed according to physical location) in the threedimensional model, remember the coordinate of each node then by Flash; After the user has disposed all nodes; Click and preserve, the form of each nodal information of preserving, send to WebService and preserve with the XML file by Flash; Like this; Next time, the user got into when checking, the Web front page layout can be showed actual building-site according to user configured information dynamic load node corresponding.
The three-dimensional model diagram of being made by 3Dax can be customized according to the environment at scene by the user, uploads to central server through information management platform then.The user can revise this model arbitrarily, generates different effects thereby reach to different users, amplifies, dwindles threedimensional model through the variation at visual angle simultaneously, is illustrated in fig. 5 shown below.
The transducer reported data is carried out data processing and analysis to administrative center by background server.The user is provided with the sensitive information of oneself relatively paying close attention to through the Web information management platform, and the Flash regular check in case the desired value that data reach critical value or reach setting occurs, will be reported to the police with the form of animation.In addition, through to lot of data analysis and contrast, can predict the variation that the job location may take place future, thereby give warning function in advance, prevent trouble before it happens.
Above said be specific embodiment of the present invention and the know-why used, if the change of doing according to conception of the present invention, when the function that it produced does not exceed spiritual that specification and accompanying drawing contain yet, must belong to protection scope of the present invention.
