The invention relates to measurement technology and is designed to measure and control the angular deviation of the object from the vertical position.Known dipmeter, consisting of housing, gaskets, suspension, two conductive plates, the dielectric strip and two lateral electrodes 
Known dipmeter, selected as a prototype, which includes a housing made in the form of a tube with a liquid and an air bubble, two pairs of piezoelectric transducers, two acoustic damper, a generator of electrical pulses and measuring device 
Known ustroystva vertical (gravity vector), due to the destabilizing influence of such environmental factors as the influence of acoustic and temperature fields. This limits the scope of use of the devices and reduces their reliability.The aim of the invention is to improve the accuracy of measurement of the angles of inclination of the object from the vertical position.This is achieved by dipmeter containing ring vukobrat, interacts with the elements of writing and reading and the associated generator survey, block coding and computing, is further provided with a lever-arm balance, mounted concentric with zvukoprovodnost, two polarizers are mounted on the ends of the rocker and interacting with zvukoprovodnost located on it reflecting load, the output is galvanically connected with zvukoprovodnost recording, the input connected to the reference input of block coding and computing, and with the output of the generator survey, sumprabum made of magnetostrictive material, and the polarizers are mounted for movement along the perimeter of Zvukovaya, the findings of the first and second elements read through the respective amplifiers-shapers reader connected to the alarm input is in block coding and computing; in Fig.3 timing chart showing the operation of the dipmeter.Dipmeter (Fig. 1) contains O-shaped (annular) magnetostrictive sumprod 1 with radius R, the acoustic absorber 2, reflecting the load 3, the lead-rocker 4, balance 5, the hinge 6, the first and second polarizers 7,8, first and second focusing elements 9,10 reading, the generator 11 of the survey, the amplifier 12 entries, the first and second amplifiers, shapers 13,14 reading unit 15 coding and computing, bus 16 control n-bus 17, data and m-bus 18 of the sign of the slope.Ring sumprod 1 is divided into two equal parts (branches) of acoustic absorber 2 and the reflecting load 3, electrically connected to the output of the amplifier 12 entries. On both sides of the acoustic absorber 2 on the branches of Zvukovaya 1 fixed lumped elements 9,10 reading. Their findings through the first and second amplifiers, shapers 13,14 reading connected respectively to the first and second signal inputs of the block 15 coding and computing. His first and second groups of outputs connected to bus 17 and data bus 18 of the sign of the slope.The reference input unit 15 coding and calculations connected with the howling and second branches of Zvukovaya 1 is fixed with the possibility of moving the first and second polarizers 7,8, which are placed on the T-shaped leash-rocker 4 balance 5 and has a kinematic connection with the axial center of Zvukovaya 1 through the hinge 6.Dipmeter works as follows. Initially it is in the initial state (Fig.1). Bus 16 control signal "Enable", which translates dipmeter in operation. Start the generator 11 of the survey, generating a rectangular videospussy with repetition frequency fop1/Top(Fig.3.a). These signals are sent to the reference input unit 15 coding and computing (Fig.2) and place it in its original state counters 29,30 and RS-flip-flop 36.Simultaneously, the signal generator 11 of the survey are held to the input of the amplifier 12 entries. At its output produces a corresponding current signal, which takes place on Wednesday magnetostrictive Zvukovaya 1 and excites under the polarizers 7,8 elastic waves torsion due to magnetomechanical conversion. Elastic waves in the next moment begin to spread in both directions from the polarizers 7 and 8 along the branches of the ring Zvukovaya 1 with wave velocity swirl Vkr.Spreading to the sides of the first and second focusing elements is tervala time (Fig.3 b,C):
T1= T3= (1) where l1,l3the distance from the polarizers 7.8 to lumped elements 9,10 read on envelope Zvukovaya determining the angular deviation of the balance-of-5 from the direction of the gravity vector.Other elastic waves propagate along the branches of Zvukovaya 1 in the direction of the reflecting load 3 reach her, reflected without changing the shape and phase of the wave and spread to the sides lumped elements 9,10 reading around and read through the total time intervals (Fig.3 b,the angular deviation of the object from the vertical:
T2= T4= (2) where l2,l4the distance from the polarizers 7.8 to reflect the load 3 on the envelope Zvukovaya.The induced analog signals read on the conclusions of lumped elements 9,10 reading due to magnetoelastic conversion arrive at the inputs of the respective amplifiers, shapers 13,14 read where it is converted into a rectangular videospussy reading (Fig.3 d,e), which switches the counting triggers 19-22 block 15 coding and computation of dipmeter (Fig.2, figs.3 e,f,and K). Their signals appear logical elements 23, 24 and run izmerit with sampling frequency fo1/T0(Fig.3 C,l).A counting pulse generators 25,26 are direct inputs of the counters 29, 30 and accumulate, forming at the end of the conversion cycle n-bit codes of the relative values of the angle of inclination of the object from the vertical |l2l4|/0,01745 R,
N1= (T2-T1)fo= 2 fo(3)
N2= (T4-T3)fo= 2 fo(4)
The slice signal triggers 21,22 through logical element OR 27 starts the one-shot 28 (Fig.3 m,n), which sets the initial state triggers 19-22. With outputs of counters 29,30 codes (3), (4) pass on the digital inputs of the Comparators 31 and the switch 33.The comparator 31 produces a bitwise comparison of these codes and generates m-bit character code angle:
N3hN1N2, (5) through which the logical element OR 32 control inputs of the switch 33.As a result, the inputs of vicites 34 with the outputs of the counters 29, 30 enter codes (3), (4) in an unambiguous manner that allows you to calculate the result code of the angular deviation of the object current value:
Nx= N1-N 2 fo< / BR>(6)
Calculated codes (5), (6) with the output unit 15 coding and computing are on the bus 17 is learn the overflow bit of the grid one (or both) of the counters 29, 30 in their output transfer signal is formed (Fig.3 l), which passes through the logical element OR 35 and switches RS-flip-flop 36 in one state. A signal is generated "Error" (Fig.3) informing about the unreliability calculated codes (5), (6) the tires on the 17 and 18 of the dipmeter.In the next moment elastic waves, bypassing elements 9,10 read, reach acoustic absorber 2 and dissipate their energy. The conversion cycle of the dipmeter is completed, it is prepared for the next conversion cycle, which is performed according to the above.The use of ferromagnetic Zvukovaya and excitation of elastic waves swirl increases the accuracy of measurement of the angles of inclination of the object as increased resistance to the effects of acoustic and temperature fields, simplifying the structure of the device, increases its reliability.

SUBSTANCE: in particular, the invention relates to transport construction and can be used at automation, for example of earth-moving machines intended to construct a road bed, as well as to arrange bases and pavements of automobile roads. A horizontal noise-proof pendulum angle meter with high sensitivity with regard to a useful signal and dampened by forces proportional to its "absolute speed", which differs by the fact that a horizontal pendulum consists of a laminated set of circular thin plates one end of which is fixed on the axis, and the other one is fixed on an unbalanced plank, which is placed in a closed tight housing made in the form of a cylinder, the axis of which coincides with the pendulum axis, fully filled with a damping liquid, mounted on the plate so that one side of the housing is installed on the plate in a hinged manner, and the other side is attached to the plate by means of an adjustment bolt, by means of which constant angle value α is set, closed by a tight cover in which there are holes with protective plugs, and a converter of useful angle β to an electric signal. As a result, the proposed device has high sensitivity with regard to the useful signal and an increased oscillation period, as well as at action of interference in the form of pulse horizontal acceleration acting in the swing plane of the pendulum; the latter obtains inconsiderable false deviation β that is damped quickly as a result of damping of the pendulum relative to "liquid heavy balanced body".
