The device provided by the invention can be used for overcoming the defects such as the low signal intensity, the instability, the short the test spacing and the like for the wireless sensor 2 in the complex working condition, improving the stability of the wireless signal in the process of long distance transmission and spanning of an obstacle, and broadening the application area of the wireless sensor 2.
Description
Technical field:
The present invention relates to a kind of transferring device that strengthens the wireless senser signal, belong to structure monitoring and detection range.
Background technology:
Wireless transmission develops along with the leap of digital radio technology rapidly in recent years; Digital radio technology has solved the strong noise problem of wireless signal; Add that wireless broad band technology has improved the transmission rate of wireless transmission greatly, make wireless transmission method show one's promises gradually in structure detection and health monitoring field.Yet, because wireless signal decay gradually along with the increase of distance, so the measuring distance of wireless senser is very limited; And barrier tends to stop or shield propagation of wireless signal midway, and the authenticity that this has had a strong impact on wireless signal has hindered the application and the popularization of wireless senser.
Summary of the invention:
The objective of the invention is to solve above-mentioned wireless senser and meet the loss of signal strength in the obstacle transmission; And wireless signal strength attenuation problem in the long distance test; Strengthen the transmission signals of wireless senser, strengthen the ability of wireless senser across obstacle and the ability of remote transmission signal.
For realizing above-mentioned purpose; The technical scheme that the present invention adopts is: between wireless senser 2 and signal sampler 1, set up signal transferring device 3; This signal transferring device 3 can be accepted the wireless signal of wireless senser 1 emission; And data are carried out interior processing, and signal is strengthened, again signal is transferred to signal sampler 1.
Described signal transferring device 3 mainly is made up of five parts such as signal picker 4, processing amplifier 5, signal projector 6, frequency conversion channel 7 and mains switches 8.Signal picker 4 is used to receive the signal of wireless senser 2 emissions; Signal processor 5 is used to receive signal and signal is carried out lossless process; Increase signal strength signal intensity; Through signal projector 6 wireless signal is retransferred to signal sampler 1 sample frequency of frequency conversion channel 7 adjustable signal transferring devices 3 again.
Described signal relay means 3 has multichannel, can receive the signal of one or more wireless senser 2 emissions simultaneously, and signal is handled respectively, transfers to signal sampler 1 again, guarantees that signalling channel is corresponding one by one.
The present invention can unite use with various types of wireless sensers, monitoring and the wireless signal that detects the wireless senser emission.
The invention has the advantages that:
1. the present invention has changed the transmission route of wireless senser signal, therefore can carry out preliminary treatment to wireless signal at data transfer phase.
2. the present invention has compensated the strength retrogression of wireless signal in transmission through signalization transferring device 3 between wireless senser 2 and signal sampler 1, has increased the distance of wireless senser acquired signal.
3. the present invention has the multichannel frequency conversion function, therefore can cooperate a plurality of wireless sensers to unite use.

Embodiment
Specify embodiments of the invention below in conjunction with accompanying drawing.
As shown in Figure 1; Use wireless senser 2 to carry out in the ground vibration test in the open air; When open-air complicated topographical conditions, when perhaps measuring distance is longer, often has barrier between wireless senser 2 and the signal sampler 1 and stop propagation of wireless signal; Perhaps since measuring distance is long cause between Acquisition Instrument 1 and the wireless senser 2 signal a little less than, even signal terminating; At this moment, on the high slope between signal sampler 1 and the wireless senser 2, set up signal transferring device 3, signal transferring device 3 is responsible for accepting the wireless signal of wireless senser 2 emissions on the one hand, and signal is carried out inter-process and reinforcement, is forwarded to Acquisition Instrument 1 again.When wireless senser 2 distance signal Acquisition Instruments 1 are far away (measuring distance greater than or approach the full test distance of wireless senser), by wireless signal constantly decay along with the increase of distance of wireless senser 2 emissions, signal is very weak or cuts off when reaching Acquisition Instrument 1; The data acquisition failure; If between wireless senser 2 and signal sampler 1, set up a signal transferring device 3, possess the function that receives signal, gains in strength and transmit, therefore can be through signal transferring device 3 UNICOM's wireless sensers 2 and Acquisition Instrument 1; In the test; Wireless signal is launched through wireless senser 2, is at first accepted by signal transferring device 3, through after the interior processing; Be transmitted to signal sampler 1 once more, guaranteed the intensity and the continuity of signal.
As shown in Figure 2, be another embodiment of the present invention, in the dynamic characteristics that detects building structure; Because the inner shear wall of building structure is more, wireless signal receives shielding serious, when adopting wireless senser 2 to test between between the levels or the next door; The very weak or phenomenons such as discontinuous even interruption of signal often occur, therefore can signal transferring device 3 be positioned over the higher position between wireless senser 2 and the signal sampler 1, perhaps be positioned over a certain penetrating place of both homonymies; In the test; Wireless signal is launched through wireless senser 2, is at first accepted by signal transferring device 3, through after the interior processing; Be transmitted to signal sampler 1 once more, guaranteed the intensity and the continuity of signal.
