Abstract
The invention discloses a soft soil layered settlement magnetic ring and a settlement monitoring method. The soft soil layered settlement magnetic ring mainly comprises a secondary controller, a power source, a reed switch and a wireless transmitting/receiving module. Information is alternatively transmitted through nodes of the soft soil layered settlement magnetic ring, so that measurement information can be prevented from being restricted by the measurement distance in an underground complex environment, and then soft soil layered settlement can be automatically and precisely monitored.
Description
Technical field
The present invention relates to fields of measurement, a kind of weak soil layering settlement magnetic ring and Monitoring method of the subsidence.
Background technology
Building skyscraper, highway and high-speed railway on soft soil foundation, due to the effect of being under pressure, soft soil foundation can occur compression, may result in settlement of foundation time serious.Therefore, before building, roadbed is accurately measured significant.
At present, the method that weak soil deep soil settlement survey uses is mainly: at underground embedment sedimentation conduit and sedimentation magnet ring before measuring, during measurement, the gauge head of internally installed magnetic sensors is put into sedimentation conduit, when running into external magnetic field, reception system will be connected, then transfer information to ground and be converted into displacement.Being limited to the environmental condition that underground is special, directly transfer information to ground and become abnormal difficult under soil layer, this causes steel ruler sedimentometer the most still to occupy the leading position of weak soil deep soil settlement survey, hinders the development of weak soil delaminating deposition automatic monitoring.
Summary of the invention
The difficulty transmitted for above-mentioned metrical information, it is an object of the invention to provide a kind of weak soil layering settlement magnetic ring and Monitoring method of the subsidence, it is achieved accurately monitor the automatization of weak soil delaminating deposition.
The sedimentation magnet ring of the present invention mainly includes secondary control device, power supply, tongue tube and wirless transmitting and receiving module.Described power supply powers to sedimentation components and parts within magnet ring, and as a kind of optimal technical scheme of the design, described secondary control device selects the MSP430 single-chip microcomputer of super low-power consumption.
Measuring before weak soil delaminating deposition, at ground punching and bury sedimentation conduit and described sedimentation magnet ring underground, such as, buried sedimentation magnet ring 1a, sedimentation magnet ring 1b, sedimentation magnet ring 1c underground, sedimentation MSP430 single-chip microcomputer within magnet ring is in the sleep state of super low-power consumption.
When measuring beginning, driven by motor gauge head declines in sedimentation conduit, is one block of annular magnet inside described gauge head；When gauge head drops near sedimentation magnet ring 1a, annular magnet within gauge head triggers sedimentation tongue tube action within magnet ring 1a and exports the pulse signal of a change, this pulse signal can activate described secondary control device and work at once, wirless transmitting and receiving module described in control transmits signals to the wireless receiving module on ground, master controller gathers displacement sensor for pull rope voltage this moment after receiving signal, and the displacement being converted to correspondence shows, after described secondary control device completes work in a dormant state on a liquid crystal display；Gauge head continues to decline, when dropping near sedimentation magnet ring 1b, sedimentation tongue tube action one pulse signal of output within magnet ring 1b can be triggered, this pulse signal can activate sedimentation secondary control device within magnet ring 1b and work at once, control wirless transmitting and receiving module and transmit signals to sedimentation wirless transmitting and receiving module within magnet ring 1a, this wirless transmitting and receiving module can be by described signal wireless transmit to the receiving terminal on ground, and receiving terminal receives such as above-mentioned flow process conversion display displacement after signal；Same aforesaid operations, when gauge head drops near sedimentation magnet ring 1c, sedimentation tongue tube magnet ring 1c within triggers signal and can pass to successively settle magnet ring 1b, settle magnet ring 1a, and then is delivered to ground and is converted into displacement and shows.
When driven by motor gauge head rises, measure once sedimentation magnet ring position further according to above-mentioned measuring method, finally take twice measurement result meansigma methods.
The present invention passes through node alternate transport information, it is possible to make metrical information in the complex environment of underground the most tested span from restriction, and then realize the automatization of weak soil delaminating deposition is accurately monitored.

Detailed description of the invention
Below in conjunction with accompanying drawing, the invention will be further described.
As it is shown in figure 1, the sedimentation magnet ring of the present invention mainly includes secondary control device, power supply, tongue tube and wirless transmitting and receiving module composition.Described power supply powers to sedimentation components and parts within magnet ring, and as a kind of optimal technical scheme of the design, described secondary control device selects the MSP430 single-chip microcomputer of super low-power consumption.
Such as Fig. 2, shown in 3,4, before measuring weak soil delaminating deposition, at ground punching and bury sedimentation conduit 2 and described sedimentation magnet ring underground, such as, having buried sedimentation magnet ring 1a, sedimentation magnet ring 1b, sedimentation magnet ring 1c underground, sedimentation MSP430 single-chip microcomputer within magnet ring is in the sleep state of super low-power consumption；
When measuring beginning, motor 4 drives gauge head 3 to decline in sedimentation conduit 2, and described gauge head 3 is internal is one block of annular magnet；When gauge head 3 drops near sedimentation magnet ring 1a, annular magnet within gauge head 3 triggers sedimentation tongue tube action within magnet ring 1a and exports the pulse signal of a change, this pulse signal can activate described secondary control device and work at once, wirless transmitting and receiving module described in control transmits signals to the wireless receiving module on ground, master controller gathers displacement sensor for pull rope voltage this moment after receiving signal, and the displacement being converted to correspondence shows, after described secondary control device completes work in a dormant state on a liquid crystal display；Gauge head 3 continues to decline, when dropping near sedimentation magnet ring 1b, sedimentation tongue tube action one pulse signal of output within magnet ring 1b can be triggered, this pulse signal can activate sedimentation secondary control device within magnet ring 1b and work at once, control wirless transmitting and receiving module and transmit signals to sedimentation wirless transmitting and receiving module within magnet ring 1a, this wirless transmitting and receiving module can be by described signal wireless transmit to the receiving terminal on ground, and receiving terminal receives such as above-mentioned flow process conversion display displacement after signal；Same aforesaid operations, when gauge head 3 drops near sedimentation magnet ring 1c, sedimentation tongue tube magnet ring 1c within triggers signal and can pass to successively settle magnet ring 1b, settle magnet ring 1a, and then is delivered to ground and is converted into displacement and shows.When driven by motor gauge head rises, measure once sedimentation magnet ring position further according to above-mentioned measuring method, finally take twice measurement result meansigma methods.
The present invention passes through node alternate transport information, it is possible to make metrical information in the complex environment of underground the most tested span from restriction, and then realize the automatization of weak soil delaminating deposition is accurately monitored.
