Description
Technical field
The invention belongs to sensor technical field, relate more specifically to a kind of MULTISENSOR INTEGRATION test macro that is applicable to bridge, pylon, skyscraper health monitoring.
Background technology
Next transducer of normal conditions can only be used for surveying a kind of physical quantity, but in many applications, for can be perfect and reflect objective things and environment exactly, often need measure a large amount of physical quantitys simultaneously.The Multifunction Sensor of being made up of some kinds of sensers then is a kind of advantages of small volume and detection system of new generation that multiple function has both; It can realize the measurement function of multiple sensors simultaneously by means of physical structures different in the senser or chemical substance and the characteristic manner that has nothing in common with each other thereof with an independent cover sensing system.
The health monitoring of bridge, pylon, skyscraper is meant building from construction or construction or after the construction, the structure of being carried out, monitoring such as stressed.At present, domestic when doing similar health monitoring, each part is relatively more independent comparatively speaking, forms the cover system accomplished a cover solution in other words.
Disclosing a kind of high-accuracy vibrating wire pressure sensor at patent CN 101603868 A, mainly is the 60%-90% that the deformation film boss diameter of work on hand film is become the deformation film diameter; Described working film body has an extension to the hydraulic joint direction; Be processed with blind hole on the extension to deformation film; Be processed with internal thread or on the periphery of extension, be processed with external screw thread on the blind pore wall, realize being threaded of hydraulic joint and extension through internal thread or external screw thread, this transducer can be realized the detection of high accuracy; But can't realize the isoparametric measurement of acceleration, can not reach the purpose of composite measurement.
In order to reach composite measurement, domestic present way through the aggregation process of a plurality of separating parts, can not be accomplished timely response in time, and real-time is relatively poor.If the full-bridge strain gauge transducer is in the high speed acquisition state always, except meeting has influence on the life-span of this transducer, also can increase the weight of the energy consumption of whole system.For the long term monitoring system, can bring the loss of manpower and financial resources, and along with monitoring time, a series of variations also can take place in sensor sensitivity and accuracy.
Summary of the invention
1, the present invention wants the technical solution problem:
Main purpose of the present invention provides a kind of integrated test system that is applicable to bridge, pylon, skyscraper health monitoring, through the cooperation of each several part transducer and acquisition module in this cover system, realizes record, the analysis of real time data; And can avoid the full-bridge strain gauge transducer to be in the state of high speed acquisition always; And the problem that produces the unnecessary data of magnanimity and wear out itself; Can be widely used in various types of buildings; Can detail record, in time react some geological disaster information, be that the later stage health analysis is saved financial resources, material resources.
2, the technical scheme that the present invention adopted:
As shown in Figure 1, integrated test system comprises transducer, data acquisition unit, on-the-spot test terminal, network interface and remote client terminal.
Transducer is used to detect measurement data such as displacement, acceleration; Data acquisition unit connects transducer through wireless or wired mode; The measurement data of pick-up transducers; Sensor signal is carried out A/D conversion and amplification, shaping, convert the signal that microprocessor can read, handle to, and realize and compunication through corresponding level conversion.The on-the-spot test terminal connects data acquisition unit through wireless or wired mode, is used to store the data of data acquisition unit collection and analysis, and test jobs is monitored in real time, calculates the storage and the analysis of various engineering parameters.Network interface will pass through the data of handling at the on-the-spot test terminal and send remote client terminal to.Said remote client terminal is connected with the on-site data monitoring terminal through network; Carry out transfer of data with sharing mode or FTP mode; To being in strange land project leader person and person skilled reflection test jobs data, instant analysis data and feedback processing information.
(1) Sensor section
Transducer mainly comprises: acceleration transducer, vibrating string type sensor, full-bridge resistance strain type sensor.
Acceleration transducer is used to measure the building uniform acceleration, has characteristics such as high reliability, working stability, sensitivity, antijamming capability be strong; Vibrating string type sensor, be used to proofread and correct resistance strain type sensor since long-term place cause data drift and record building slowly sink and stressed etc. for a long time; The full-bridge resistance strain type sensor is used for measuring destructive natural calamity processes such as earthquake, and the extent of damages such as building have precision height, easy for installation, characteristics such as sensitivity is good.
The invention is not restricted to the sensor, according to actual needs, can also increase the transducer of other type, with other parameters such as detected temperatures, demeanour.

(3) course of work of transducer and data acquisition:
Vibrating string type sensor check and correction full-bridge resistance strain type sensor is owing to put drift, the sinking slowly of monitoring building and stressed that causes for a long time.Because reaction speed is relatively slow, long term monitoring numerical stability, nothing are put drift for a long time, therefore are in low speed long-term work state.
Acceleration transducer triggers and cuts out the full-bridge resistance strain type sensor, and the collection of signal is in the high speed operation state for a long time, detects the acceleration of building in real time.
Resistance strain type sensor is in treats worker's state, and whether working controlled by acceleration transducer.When measured object receives when acutely rocking, the acceleration transducer data take place sharply to change, and exceed the acceleration early warning value; And duration overtime threshold values; At once starting resistance strain-type full-bridge carries out high-speed signal acquisition, and record building engineering parameter such as displacement in whole process changes, when accekeration is lower than early warning value; And duration overtime threshold values, full-bridge resistance-strain type get into and close closed procedure.In this process, data show storage in real time, and through the magnitude of physical quantity between each acquisition module numerical value, obtain project data and curve, in the engineering staff health such as building are assessed fully.
3, the beneficial effect that the present invention produced:
Cooperation through each several part transducer and acquisition module in this system; Realize the function of integration test; And through the application of acceleration transducer, overcome the state that the full-bridge strain transducer is in high speed acquisition always, can be widely used in various types of buildings; Can detail record, in time react some geological disaster information, be that the later stage health analysis is saved financial resources, material resources.
