Specific embodiment
A step of the invention is described in detail below in conjunction with the accompanying drawings.
As shown in figure 1, the elevator cage position detecting device and elevator track deformation detecting device are used as data
The signal input part of collecting circuit board, the data acquisition circuit plate is that the data with A/D translation functions of autonomous Design are adopted
Collector plate, because there are two tracks underground, therefore needs two data collecting circuit boards；The data acquisition circuit plate is total with CAN
Line is connected with OSD video combining circuits, and the input of OSD video combining circuits can connect a camera, for showing underground ring
The information such as run location, the measuring point of rail fault position, the current time of border image and current elevator cage；OSD is regarded
The output end of frequency combiner circuit is connected with video cassette recorder, and video cassette recorder can receive the image letter of other multi-path cameras
Number, a piece of detachable RAM card is included in video cassette recorder, after every subsystem end-of-job, RAM card is taken out by staff
Read video data.Miniscope is used for observing system real-time working video and carries out video playback, and the system is by lithium electricity
Pond powers.
After whole detecting system is started working, the runner of elevator cage position detecting device is first close to track, so
The signal pulse gathered by Hall sensor before removing elevator cage position detecting device manually afterwards.With elevator
Decline, the Hall sensor on runner can constantly produce the signal pulse, signal pulse to be received by data acquisition circuit plate,
And the number of pulses for currently being gathered is recorded, the run location of real-time elevator can be conversed.
While elevator declines, elevator track deformation apparatus also work at the same time.When track is undeformed and is broken,
Guide wheel on elevator will not produce vibrations and displacement, and the irony baffle plate on guide wheel bearing would not be moved；Opposite, if operation
When track occurs in that larger deformation and fracture, the guide wheel on elevator is bound to produce skew, so as to the iron on dynamic bearing
Matter baffle plate is moved together so that eddy current displacement sensor increases or reduce with the distance of irony baffle plate, current vortex displacement sensing
The size of current that device sends can also increase or reduce.Data acquisition circuit plate can judge that elevator is worked as by the change size of electric current
The weight of the running track deformation degree of front position, if deformation degree exceeds prescribed limit, operation is judged to by the location point
Rail fault point, and the depth of the location point is preserved and is sent on OSD video combining circuit plates.
While elevator declines, borehole wall environment and rail fault point display device also in real-time working, small-sized display
Screen will normally show taken the photograph borehole wall picture.Multiple AV cameras are responsible for shooting environment picture comprehensive in the borehole wall, then regard
Frequency video recorder stores into SD card captured picture.Each camera take the photograph picture be finally integrated into a screen show
Show, wherein there is the signal input part of camera all the way as OSD video combining circuit plates, and OSD video combining circuits plate can be by
The picture that the position of rail fault point that data acquisition circuit plate is gathered, the parameter synthesis of track deformation are taken the photograph to the road camera
In face.
