Label information is passed to computer 31 and given birth on backstage by the communication modes such as net, bluetooth, Zigbee, WLAN or RS232, RS485
At account, it is preferable if be whole kilometrage label, system meeting automatic trigger mileage correction at the label, to reduce mileage
Correct frequency, if having disease by intelligent recognition at this computer 31 can automatic marking, that is, control vehicle-mounted reader fixed
Defect information is written in the label of position, in order to later period check.If travelling process of passing through tunnel structure size changes location, mark can be passed through
Prior notice cruising inspection system is signed, cruising inspection system reaches the position and changes light-source brightness, exposure parameter automatically, to change image scape
Deep effect, shooting clear image.Preferably, vehicle-mounted reader is based on RFID technique.The tunnel cruising inspection system of the present embodiment passes through
Positioning device 35 is read or write-in positioning label, can carry out the mileage correction of the label of disease point, mobile platform 2 of detecting a flaw, convenient
The reinspection in later period, while mileage correction also improves the accuracy of disease point location, has reached the quasi- technology effect of inspection positioning
Fruit.
More preferably, computer 31, display 32, synchronization encoders 33, data collector 34, tunnel inspection image collector
Setting 1, positioning device 35, detachable be set to is detected a flaw on mobile platform 2 respectively.The tunnel cruising inspection system of the present embodiment uses can
The modularized design of detachable improves the convenience of system convenient for can individually store, transport.
Now the course of work of the present embodiment is illustrated:
Tunnel cruising inspection system overall workflow is as follows:
S1: vehicle driving enters tunnel area, starts to detect；
S2: synchronization encoders 33 are advanced with double track inspection car from triggering clock cycle signal, and simultaneously by signal
It is sent to CCD industrial camera and light source controller, makes its synchronous working, and complete an image after the fixed distance of traveling
Acquisition；
S3: in double track inspection car driving process, whole kilometer mark is carried out by RFID location system, in tunnel change in size
By RFID label tag prior notice computer 31, tunnel cruising inspection system reaches the position and changes light-source brightness, exposure ginseng automatically at place
Number, thus change image depth effect, shooting clear image
S4: data collector 34 acquires image real-time perfoming, and synchronization encoders 33 is combined to carry out corresponding image
Pass through various communication modes after numbering: on the communication modes such as Ethernet, bluetooth, Zigbee, WLAN or RS232, RS485
It is transmitted to computer 31；
S5: intelligent identifying system realizes percolating water identification by topography's gray scale difference opposite sex feature in computer 31,
It realizes that pipeline falls off by linear gradation otherness feature and waits automatic identification functions.For the disease point that identification obtains, pass through
Corresponding information is written at positioning label in RFID positioning device 35, checks convenient for the later period；
S6: the tunnel image call by identifying and marking disease point is passed through algorithm for synchronization 6 by computer 31
The image that a CCD camera 11 obtains, which is spliced, shows complete tunnel liner image with more intuitive.
The tunnel inspection image collecting device 1 of the present embodiment is being detected a flaw on mobile platform 2 by setting, and coupled computer
31, display 32, synchronization encoders 33, data collector 34, carry out the sync pulse jamming in tunnel, disease recognition, splicing in real time with
Display, wherein the image tractability that the tunnel inspection image collecting device 1 based on embodiment 1 acquires improves tunnel inspection
The recognition speed of system and splicing speed, so that the real-time display at scene can be realized, user can by the content of real-time display into
The in-situ processing of row inspection notifies that relevant department is handled in time, substantially increases tunnel inspection timeliness, reaches
It is high-efficient, detection time is short, accuracy is high, the technical effect of missing inspection is less likely to occur.
Embodiments of the present invention are explained in detail above in conjunction with attached drawing, but the present invention is not limited to above-mentioned implementations
Mode.Even if to the present invention, various changes can be made, if these variations belong to the model of the claims in the present invention and its equivalent technologies
Within enclosing, then still fall within the protection scope of the present invention.
