The invention provides a kind of concrete impermeability test system of automatic monitoring, it comprises: impermeability test instrument, test specimen and watch-dog; Wherein: described test specimen is installed on described impermeability test instrument; Described watch-dog, is oppositely arranged with described test specimen by support installing above described impermeability test instrument, for test specimen described in BR end face picture and preserve.
Preferably, described watch-dog comprises video camera, DVR, and the end face picture of test specimen described in described video camera BR, is saved in described DVR, and multiple video camera may correspond to a DVR, cost-saving.
Preferably, described surface of test piece is coated with and meets water color shifting ink layer.Because concrete intrinsic colour is darker, after infiltration, color change is not clearly, when seeping water fewer, whether very difficult resolution there occurs infiltration, smears after meeting water color shifting ink, surface of test piece has just started as white, after infiltration, meet water color shifting ink bleach, expose concrete color, color change is obvious, just can judge when seeping water less.
Preferably, the thickness of described chance water color shifting ink layer is 0.5mm.
Preferably, described impermeability test system also comprises monitor terminal, and described monitor terminal is connected by wire signal or wireless signal with described watch-dog; Described end face picture is also uploaded to described monitor terminal for timing by described watch-dog.Staff checks the progress of test figure and test by monitor terminal.
Preferably, described monitor terminal is mounted with gray level image recognition system, reads the half-tone information of described end face picture for timing.Without the need to people for judging whether infiltration, ensure that the accuracy of test figure, decreasing the workload of staff simultaneously.
Preferably, described monitor terminal also comprises SMS platform, for described half-tone information is sent to mobile terminal with the form of note.Staff need not observe before monitor terminal, and the note namely by receiving understands test process and test findings, takes appropriate measures in time.
Preferably, the end region of described test specimen is divided into neighboring area and zone line; Described half-tone information comprises neighboring area half-tone information and zone line half-tone information.When infiltration occurs in neighboring area, illustrate do not have good seal, need to reseal test specimen, zone line is region of normally seeping water, and explanation is that concrete seeps water.
Preferably, described periphery infiltration region is from the annular region between the annulus and the edge of described test specimen of the edge 30mm of described test specimen; Described zone line is the border circular areas of the annulus inside of edge 30mm from described test specimen.
Compared to prior art, the present invention has the following advantages:
(1) the concrete impermeability test system of automatic monitoring provided by the invention, watch-dog installed by original impermeability test instrument, automatically impermeability test process is monitored by watch-dog, and record is carried out to test figure, within 24 hours, treat at the scene without the need to staff, and staff can be switched by video, observe the working condition of multiple stage test instrument simultaneously, decrease the workload of staff, cost compare is low simultaneously;
(2) watch-dog can the overall process of keeping records test, if staff fails to observe in time the time that infiltration occurs, can again observe infiltration situation and result under accurate recording by playback.

Embodiment
Elaborate to embodiments of the invention below, the present embodiment is implemented under premised on technical solution of the present invention, give detailed embodiment and concrete operating process, but protection scope of the present invention is not limited to following embodiment.
embodiment 1:
The present embodiment describes the concrete impermeability test system of automatic monitoring of the present invention in detail, as shown in Figure 1, it comprises impermeability test instrument 1, test specimen 2, watch-dog 3 and monitor terminal 4, watch-dog 3 comprises interconnective video camera 31 and DVR 32, and DVR 32 is connected by wire signal or wireless signal with monitor terminal; Wherein: every six test specimens 2 are installed on an impermeability test instrument 1, watch-dog is installed on the upper end of test specimen 2 by support 4, video camera 31 and test specimen 2 are oppositely arranged, for the end face picture of BR test specimen 2, and its timing is saved in DVR 32, DVR 32 is by picture uploading in monitor terminal 4, and staff checks picture by monitor terminal 4, learns test process and test findings.
