Abstract

The present invention relates to an inclinometer for observing inclination pitch change of the earth crust, which belongs to the technical field of an inclinometer and is particularly to suitable for places of crustal inclination solid tide measurement, seismic surveillance predication, reservoir large dam landslide monitoring predication, etc. A main body part of the inclinometer is composed of a passive pendulum, an inverted pendulum, a middle pendulum plate and a machine frame, wherein an upper balance plate and a lower balance plate of the middle pendulum plate are connected with an electromagnetic driver and a sensor which is connected with a recorder by a pre-amplifier and a PID controller, and the output end of the PID controller is connected with the electromagnetic driver.

Description

The inclinator that observation earth's crust degree of tilt changes
The invention belongs to the inclination field, be specially adapted to occasions such as ground tilt tide measurement, the pre-utmost point of seismic monitoring and the forecast of reservoir dam landslide monitoring.
At present, the instrument that observation earth's crust degree of tilt changes mainly contains inclination of horizontal pendulum tiltmeter water pipe and steam bubble inclinator etc., and the common drawback of these inclinators is that sensitivity is lower, only is about one millisecond, and this precision is far from suitable from necessary requirement.
At the strong point of above-mentioned technology formerly, task of the present invention provides a kind of horizontal folding pendulum clinometer.
The present invention implements (Fig. 1) by following technical measures, one end of frame 8 with just put 1 and be connected, the other end with put 5 and be connected, the above and below of middle balance 4 is established activity balancing plate 3 and stable equilibrium plate 2 respectively, electromagnetic driver 6 is connected with balance plate 2 respectively with accurate infrared sensor 7.Accurate infrared sensor 7 is connected with prime amplifier 9 input ends, the output terminal of prime amplifier 9 is connected with the input end of PID (proportion integration differentiation) controller 10, and the output terminal of PID (proportion integration differentiation) controller 10 is connected with register system 11 and electromagnetic driver 6.
Advantage of the present invention is that (one) adopts horizontal folding pendulum and accurate infrared electronic technology, can make sensitivity improve 1-2 order of magnitude at least.(2) owing to have good symmetry in the horizontal folding pendulum design, therefore can suppress the interference that the other direction perpendicular with observing inclination direction tilts, thereby obtain stable enlargement factor.(3) adopt negative feedback electromagnetic compensation control system, can overcome the nonlinear problem of suspension and feed rod detection system in traditional horizontal pendulum method.(4) adopt negative feedback electromagnetic compensation control system, can increase range of dynamic measurement.
Description of drawings is as follows:
Accompanying drawing 1. ground tilt tide folding pendulum measuring system schematic diagrams.
The present invention is further described as follows below in conjunction with accompanying drawing:
When earth's crust run-off the straight, just putting 1 and put the 5 a certain angles that will tilt, middle balance 4 will produce (horizontal shift) balance plate 2 and also produce a horizontal shift thereupon, detect the shifted signal of middle balance 4 through accurate infrared displacement sensor 7 after, send into the input end of PID (proportion integration differentiation) controller after sending prime amplifier 9 to amplify the result of detection, (proportion integration differentiation) PID controller is regulated the working current in the solenoid, thereby the driving force that electromagnetic driver 6 is changed middle balance 4, balance just is controlled in all the time and puts in the middle of making, put perpendicular position, thus, working current in the electromagnetic driver can reflect the size that the earth's crust tilts, PID (proportion integration differentiation) controller will be when will regulating the result and sending into electromagnetic driver, also give register system, to note earth's crust tilt signals with this adjusting result.
