Description
Technical field
The utility model relates to a kind of system and method that is used to measure the displacement of side slope crack, belongs to slope and land slide disaster remote real time monitoring field.
Background technology
The crack that produces before the open-pit slope landslide is the position of sliding mass change in displacement maximum, becomes us and monitors the simplest of landslide and effective means, usually changes when reaching 4-5cm/ hour when the crack, in 24 hours the generation of landslide will be arranged.
At present domestic to the monitoring in crack occurring mainly by manually finishing before the open-pit slope landslide, by distance with two point of fixity between ruler measurement side slope crack, measure the displacement of side slope crack, not only precision is low but also have the monitoring of certain risk, particularly night very difficult; Automatic monitoring system sensor complex in the past relies on the GPRS network transmission signals, need pay communication expense operating cost height, needs fixed power source that difficulty is installed; Therefore need a kind of suitable Production of Strip Mine environment, operating cost is low, mounting arrangements is easy, need not fixed power source, do not rely on GPRS network, can long distance wireless the crack delta data be transferred to monitoring computer, computer monitoring software forms change curve automatically, for the utility system of prediction landslide reference.
Summary of the invention
The present invention utilizes stay-supported displacement transducer technology and Zigbee radio network technique to form the long-range monitoring system of freely moving of slope displacement just for overcoming the above problems.System is transmitted by on-the-spot displacement data collection and monitoring center's receiving and analyzing two parts are formed, it is characterized in that: the stay-supported displacement transducer (1) that on-the-spot displacement data is gathered translator unit is connected to analogue collection module (2) input end, analogue collection module (2) output terminal is connected to Zigebee wireless transmitter module (3), solar powered module (4) is partly powered for collection in worksite, the Zigebee wireless receiving module (5) of monitoring center's receiving and analyzing part is connected to computing machine (6), the MCGS configuration software is installed on the computing machine, finishes the curve display of displacement data.
Stay-supported displacement transducer (1) is to be fixed on 6 meters long angle bar (10) upward to be connected with spud pile (7) when mounted, is in the stable group in crack, and the sensor measurement stay cord is connected by the 1 meter long connection cord and the group's spud pile (9) that slides after pulling out fracture width.Arrange that like this distance between two spud piles reaches 7 meters at least, can improve the relative variation precision of measuring the crack displacement.
The displacement of side slope crack is the variation that comprises level and vertical two direction of motion, also want the measuring vertical direction to what the measurement in side slope crack should be measured horizontal direction, so just make the complexity of the measurement change of crack displacement, be not easy to measure and analyze, find a kind of vertical change that promptly comprises of similar daily measurement to comprise the measurement means that level changes again, will make to measure and oversimplify, we have selected the stay-supported displacement transducer for this reason.
The stay-supported displacement transducer can convert mechanical displacement to electric signal gageable, linear ratio.When testee produces displacement, spur coupled pull rope, pull rope drives the sensor gear train and sensing element rotates synchronously; Reverse when mobile when displacement, the revolving gear of sensor internal is the automatic drawing back pull rope, and stretches at pull rope and to keep its tension force constant in the receipts process, thus export one with the directly proportional electric signal of testee amount of movement.Sensor steel cable winding displacement mode adopts automatically evenly winding displacement, assurance to have higher independent linearity precision and long sensor serviceable life.
The simplification that the application of stay-supported displacement transducer becomes problem, the stay-supported displacement transducer passes through flexible, the steel wire length that can pull out and withdraw changes, convert electric signal gageable, linear ratio to, be fixed on the elongation of the flexible steel wire on both sides, crack, be promptly to comprise the variation that horizontal shift also comprises perpendicular displacement, so just make simple and clear that the displacement measurement in crack becomes.
The displacement data that the stay-supported displacement sensor arrives, need long distance wireless to be transferred on the computing machine of surface mine office building and store analysis, wireless transmission has partly adopted the Zigebee wireless sensor network, the Zigbee wireless network module can be extremely low power consumption realize communication distance far away, for in-site measurement is partly realized the solar powered condition that improved, make in-site measurement partly have removable performance, satisfied the requirement at surface mine scene, replace the GPRS communication modes of slope monitoring system in the past, saved daily network communication expense.
The MCGS configuration software is installed on the monitoring computer, the data of each sensor are stored analysis, produce data variation curve intuitively automatically, reference during for our analysis of slope crack state and variation tendency.
