Abstract
The utility model relates to a dipmeter with a function of temperature compensation, which solves the technical problem that the measuring precision of the dipmeter is decreased because a dip sensor is greatly affected by the environmental temperature. The utility model adopts the technical scheme that the dipmeter comprises a shell and a circuit board, wherein the circuit board is arranged in the shell and is provided with a CPU and a dip collecting circuit; a temperature collecting circuit and a temperature compensation module comprising a heater are additionally arranged in the circuit board in the shell; the temperature collecting circuit collects the environmental temperature signals in the shell and transmits the signals to the CPU for processing; and the CPU outputs control signals to an input end of an electric heater. The utility model has the advantages that the environmental temperature in the shell of the dipmeter is collected in real time through the temperature collecting circuit, and when the environmental temperature falls, the heater is started for heating through the control signals processed and output by the CPU to ensure that the environmental temperature is constant, thereby improving the accuracy of the dipmeter.
Description
Technical field
The utility model belongs to bridge parameter measurement field, is specifically related to be used to measure the instrument of bridge compressive strain degree, particularly has the measuring instrument that helps the control survey precision of temperature compensation.
Background technology
In the maintenance work that builds a bridge, especially for a long time be used for the bridge equipment that traffic is carried, long-time travelling owing to large-scale loading vehicles such as automobile, trains, cause the easy pressurized of bridge and form distortion, for fear of the generation of accident, slip-stick artist or maintainer need regularly bridge equipment to be checked and repaired.In the prior art, generally adopt drift indicator, principle is to measure the pressure range degree of bridge by obliquity sensor, and then the data of gathering are inputed to computer calculates, and judges the damaged condition of bridge.It is very big that but obliquity sensor is subjected to the influence of environment temperature, and the data that cause importing behind the computer are inaccurate.Prior art at this way to solve the problem is being data when the data under this temperature are become standard temperature according to fortran on computers, because transformation for mula can not generate or calculate accurately, such conversion then can cause the actual measurement levels of precision to descend greatly.
The utility model content
The utility model will solve the technical matters of the degree of accuracy decline that causes the measuring instrument measurement owing to obliquity sensor is influenced by environmental temperature, designed a kind of drift indicator with temperature compensation, consider that obliquity sensor is influenced by environmental temperature, so environment temperature being carried out constant temperature handles, guarantee under the state of constant temperature, to measure, thus the degree of accuracy of raising measuring instrument.
The technical solution adopted in the utility model is, a kind of drift indicator with temperature compensation, comprise housing in the structure of measuring instrument, be arranged on circuit board in the housing, that have CPU and inclination angle Acquisition Circuit, set up the temperature compensation module that temperature collection circuit and well heater are formed in the circuit board in housing, ambient temperature signal in the temperature collection circuit collection housing is sent to CPU and handles, and CPU outputs control signals to the input end of electric heater.
The beneficial effects of the utility model are: gather environment temperature in the measuring instrument housing in real time by temperature collection circuit; when environment temperature descends; processing output control signal by CPU heats up heater starting, guarantees ambient thermostatic switch, thereby improves the precision of measuring instrument.
Below in conjunction with accompanying drawing the utility model is elaborated.

Embodiment
Referring to Fig. 1, a kind of drift indicator with temperature compensation, comprise housing 1 in the structure of measuring instrument, be arranged on circuit board 4 in the housing 1, that have CPU and inclination angle Acquisition Circuit, set up the temperature compensation module that temperature collection circuit 2 and well heater 3 are formed in the circuit board 4 in housing 1, ambient temperature signal in the temperature collection circuit 2 collection housings 1 is sent to CPU and handles, and CPU outputs control signals to the input end of electric heater 3.
Above-mentioned inclination angle Acquisition Circuit comprises and is used to measure the axial obliquity sensor U1 of bridge, is used to measure the bridge obliquity sensor U2 radially and divider resistance, the capacity cell of peripheral matched that divider resistance is delivered to voltage division signal the input end of CPU.
Above-mentioned CPU is the C8051F350 single-chip microcomputer.
Above-mentioned temperature collection circuit 2 comprises temperature sensor U3 and peripheral matched resistance, and temperature sensor U3 gathers ambient temperature and is converted to the input end that electric signal is sent to CPU.
The model of above-mentioned obliquity sensor U1, U2 is SCA-103T.
The utility model is when concrete the use, well heater 3 be set in obliquity sensor U1, U2 around, can formerly configure standard temperature, for example be set at 30 ℃, temperature collection circuit 2 is gathered environment temperature in real time, in case be lower than 30 ℃, the CPU heater 3 that transmits control signal heats up, up to reaching 30 ℃, CPU sends control signal and stops well heater 3.So, can guarantee that the working temperature of obliquity sensor U1, U2 remains on 30 ℃ constant temperature.More than said standard temperature can set according to the temperature of different regions.
