Description
Technical field
The present invention is to be related to a kind of inclination monitoring early warning system, is to be related to one kind for foundation pit enclosure structure wall specifically
Body or the fixed wireless inclination monitoring early warning system of deep soil lateral displacement belong to Geotechnical Monitoring technology neck
Domain.
Background technique
In recent years, large- and-medium size cities population steeply rises, and land resources utilization is more nervous, to meet public and civilian setting
The construction demand applied, such as subway station, underground parking, the civilian warehouse in underground, to improve the deep basal pit of land utilization ratio
Engineering is able to broad development.Due to the mismanagement of increase and the construction of scale, occur not during Construction of Deep Excavation Engineering
Few accident, causes huge economic loss and casualties, not only delays the duration, and causes undesirable social shadow
It rings.
Field monitoring is a kind of important means for perceiving supporting construction and ambient enviroment response in work progress in time,
In, the lateral displacement of deep soil or wall is one common, safe for evaluating deep footing groove enclosing structure and the periphery soil body
The important indicator of situation.The existing monitoring in China standardizes still by the way of artificial on-site land survey, and major defect is not only to consume
Biggish manpower and material resources are taken, and the period acquired is longer, real-time is poor；Data processing later uses the side of manual transcription
Formula, inefficiency cause monitoring and warning to be likely to lag behind accident.In addition, if encountering severe geological environment or weather
Condition, manual measurement are faced with huge risk again.
In view of the above problems, the experts and scholars for being largely engaged in geotechnical engineering study this, especially it is wireless from
Dynamicization monitoring aspect achieves more progress.As Chinese patent 201320653237.0 discloses a kind of fixed wireless depth of threadiness
Hole inclinometer and deep hole inclination measurement system, the basic of the device are constituted by multiple deviational survey unit mounted on top in measured hole, deviational survey
Unit connects device on well by a RS485 bus, and device can carry out data processing, the reception of measurement data and hair on well
It send；Similar principles have Chinese patent 201110133738.1；Chinese patent 200910039248.8 discloses one kind wirelessly certainly
Dynamic dual-axis inclinometer, principle are will to connect one with the inclinometer that measurement sensor is formed based on mems accelerometer can control
The motor system that the component is run up and down realizes component operation up and down in inclimation measuring duct in conjunction with automatic time controller, with
Continuously measure the stratum lateral displacement of two orthogonal horizontals (X, Y) in entire soil layer, data transmission be based on GSM or
GPRS network realizes the wireless automatic of monitoring；Similar also Chinese patent 201710180368.4 discloses one kind and is used for

201610852476.7 disclose a kind of method of real-time for underground deep layer earth horizontal displacement, between inclinometer group
Communication mode is to connect to realize by cable, if the measurement for interrupting lower part inclinometer group is transmitted work by part cable Joint failure
Make, and the cost of later maintenance is larger, on the other hand, the lateral displacement calculation formula of the invention assumes that bottom is fixed point, this
And the certain deviation of physical presence.To sum up, there are still many technological deficiencies for technology disclosed in above-mentioned patent.On the one hand, mesh
Preceding existing wireless automatic monitoring device, can not achieve full Wireless, as device on deviational survey unit and well connection still
For wired forms, power supply also mostly uses wired mode, so that installation is complicated, mounting condition is limited, and later maintenance cost is higher,
Once the damage for wired connection occur can not repair in time in measurement；On the other hand, cost is higher, is not easy to make on a large scale
With；In addition, the measuring result error that existing measurement method and computational accuracy obtain is big, there is the wind that not would know that measured deviation
Danger is not able to satisfy effective monitoring and warning demand immediately.
With the development of technology with the raising of monitoring requirements, monitoring technology must towards automation, real time implementation, long-range,
Wireless penetration and intelligent and develop.In recent years, wireless sensor network technology (WSN) and MEMS (MEMS) by feat of its
Itself unique advantage influences rapidly and is gradually applied to hypogee monitoring field, passes through combination in view of the above technical problems
WSN and MEMS technology provide that a kind of monitoring deviation ratio is low, early warning is sensitive, it is fixed wireless for multi-party short range and remotely to monitor
Inclination monitoring early warning system, low in cost, install convenient, by great application and promotion prospect.
