Further, the settlement sensor 334 of the integrated gauge head 33 is made from eddy induction type sensor, internal
Be provided with magnetic sensors, make its run into sedimentation magnet ring 34 when, magnetic sensors produce signal, and when away from sedimentation magnet ring 34 when
The blackout.The settlement sensor 334 is connected with signal cable 44, and its settlement sensor 334 gathers and by signal electricity
Cable 44 transmits the location triggered signal of output settlement point.The output signal of the settlement sensor 334 passes through on signal cable 44
It is transmitted to master controller；The signal cable 44 is embedded with steel ruler and signal wire, and steel ruler is used to bearing sensor and steel ruler itself
Weight, signal wire are used for the output signal for transmitting settlement sensor 334.
Monitoring principle of the present invention is as follows：
After the present invention is connected to measurement Monitoring instruction or is timed measurement, settlement measurement, data acquisition and control are carried out first
Molding block sends control signals to motor control module, drives dragging motor 28 and drives integrated gauge head 33 descending.Lower limit
Whether the integrated gauge head 33 of the detection of switch 359 reaches sedimentation and the bottom position of tipping tube 36, if integrated gauge head 33 has arrived
Up to bottom position, then dragging motor 28 and integrated gauge head 33 stop descending.
Integrated gauge head 33 was delayed in bottom after stopping a period of time, and dragging motor 28 drives integrated gauge head 33 up,
Rotary encoder 23 is used to detect the distance that integrated gauge head 33 is passed by sedimentation and tipping tube 36 are managed.
The position of the detection sedimentation magnet ring 34 of settlement sensor 334 of integrated gauge head 33, when integrated gauge head 33 is by heavy
When dropping magnet ring 34, settlement sensor 334 sends signal, and data acquisition records position now, respectively P1, P with control module
2、…、Pn.After being measured, settlement sensor 334 rests on the mouth of pipe.It can be calculated according to the position of each sedimentation magnet ring 34
Its relative to benchmark sedimentation magnet ring 34, i.e. it is each sedimentation and the bottom position of tipping tube 36 installation settle magnet ring I 341 away from
From L i=Pi-P1, because the position of benchmark sedimentation magnet ring I 341 has almost no change, therefore, distance L i change reflects
The sedimentation of each sedimentation place aspect of magnet ring 34.
When settlement sensor 334 detects the sedimentation magnet ring 34 of specified quantity, or the detection sedimentation sensing of rotary encoder 23
After the Top Runby of device 334 reaches setting value, or upper limit position switch 358 detects the integrated gauge head of gauge head 33, the band of dragging motor 28
Movement and motor-driven integrative gauge head 33 stops up, completion settlement measurement process.
Data acquisition preserves this settlement measurement data into memory 17 with control module, subsequently into inclination measurement mistake
Journey.
Inclination measurement process is identical with the descending control process of the gauge head of settlement measurement process.
Data acquisition sends control signals to motor control module with control module, drives dragging motor 28 and drives one
It is descending to change gauge head 33.Lower position switch 359 detects whether integrated gauge head 33 reaches sedimentation and the bottom position of tipping tube 36, if
Integrated gauge head 33 has arrived at bottom position, then dragging motor 28 and integrated gauge head 33 stop operating.
Integrated gauge head 33 was delayed in bottom after stopping a period of time, and dragging motor 28 drives integrated gauge head 33 up,
Rotary encoder 23 is used to detect the distance that integrated gauge head 33 is passed by sedimentation and tipping tube 36 are managed, when integrated gauge head 33
After being up to the gauge length of setpoint distance, dragging motor 28 and integrated gauge head 33 stop it is up, it is stable according to the short time of setting
Afterwards, inclination sensor 332 measures angle of inclination.Then, dragging motor 28 drives integrated gauge head 33 to continue up, up 1
Stop after gauge length, then measure, so circulate repeated measurement angle of inclination.
After the integrated out-hole run of gauge head 33 points reach setting measuring point number, i.e. several setting gauge lengths, dragging motor
28 and integrated gauge head 33, positive stroke inclination measurement terminate.Then, dragging motor 28 and up enter of integrated gauge head 33 are changed
Into position-limit mechanism 35, reversing motor position switch 27 starts the rotation of the opposite direction of rotating reversing motor 26, carries out revesal
Inclination measurement.Revesal inclination measurement is identical with the control process of positive stroke inclination measurement, after the completion of revesal inclination measurement, most
Integrated gauge head 33 is up eventually and is parked in commutation position-limit mechanism 35.Data acquisition preserves this inclination measurement number with control module
According into memory 17.
The data acquisition of master controller completes sedimentation and inclined data acquisition and monitoring with control module, and will measure number
Stored, analyzed and processed and exported according to by being connected, being uploaded to Surveillance center's PC main frames 3 with internet by GPRS, master control
Device processed is subjected to the control command of Surveillance center's PC main frames 3, and realize only needs to sedimentation and inclined data acquisition and monitoring, manager
The measurement data uploaded on Surveillance center's PC main frames 3 to the device analyzes and processes.
The foregoing is only presently preferred embodiments of the present invention, be not intended to limit the invention, it is all the present invention spirit and
Within principle, any modification, equivalent substitution and improvements made etc., it should be included in the scope of the protection.
