Description
Technical field
A kind of survey instrument of the utility model is specifically related to a kind of pipe diameter measuring device based on photographic process, is used for measuring the pipeline diameter of various different sizes.
Background technology
Along with the high speed development of various state-of-the-art technologys, modern urban construction is constantly carried out, and various urban pipe network can be described as the vitals that maintain city operations, has been penetrated into each corner in city.And along with the step of urban development, urban pipe network is also constantly newly-built and transform, and such as the deficiency of the municipal drainage ability that constantly cruelly spills in recent years, need to transform and install additional modern control technology to existing unwatering system; Need to install transformation of the measurement instruments such as calorimeter and heating pipeline etc. additional in order to change the method by heat metering that heat supply popularizes rapidly by the irrationality of area metering.And in the process of transforming, because many pipelines are of the remote past, the reasons such as wiring complexity and managerial confusion are difficult to find the initial parameter of pipeline, such as data such as calibers.
And tackle at present this above-mentioned situation, the method for mainly taking is to use in the pipeline well instrument such as tape measure to carry out in-site measurement, record on the spot by manpower, the data of manual record is added up after the measurement again and files, again by the statistics construction.Can there be many problems in such mode of operation, such as use the instrument such as tape measure to caliber measurement waste time and energy, need human cost large; Manually measurement data is recorded and may go wrong; Manual record added up file is wasted time and energy equally and Input Process also might go wrong, these problems all can affect the duration of a project, and improve construction cost, have increased the uncertainty in the work progress.
The utility model content
The purpose of this utility model provides a kind of pipe diameter measuring device based on photographic process, can conveniently measure the pipeline diameter of various different sizes, and can automatically record, add up and store the caliber data that record, when improving measurement accuracy, reduce human resources, reduced labour cost.
Concrete technical scheme of the present utility model is as follows: based on the pipe diameter measuring device of photographic process, comprise survey instrument part and data analysis processing section, described survey instrument partly comprises crossbeam, gage beam, camera and the standard metre bar that is used for calibration, wherein camera is installed on the crossbeam, two gage beams are parallel to each other and lay respectively at the both sides of camera, and two gage beams are connected with beam vertical, the shooting direction of camera and gage beam to stretch out direction consistent; Described data analysis processing section comprises data correction module, analysis and control module and data memory module, carries out data between each module and transmits; The data analysis processing section is controlled camera and is carried out data with the image storage unit of camera and transmit, and simultaneously data analysis processing section operates to realize the input of steering order and the demonstration output of measurement data by the user.
In the described survey instrument part, be respectively equipped with fixing gauge point at two gage beams, can guarantee when measuring different pipelines, pipeline center is constant to the distance of camera, in the situation that this distance remains unchanged, camera focus also remains unchanged, the size of the pipeline that camera is taken on measure-alike photo is directly proportional with the pipeline physical size, guarantees the accuracy of data measured.
The beneficial effects of the utility model:
The survey instrument part, since about two gage beams be parallel to each other and perpendicular with crossbeam, therefore when two gage beams block respectively the pipeline section two ends, crossbeam length between two gage beams is the pipeline section diameter, then can calculate the measurement size of unit sizes representative on the photo by the photo of under the identical parameters facilities, taking standard metre bar, again by drawing the duct survey size with mutually comparing of photo.This survey instrument part-structure is simple, easy and simple to handle, and workload is little, and measurement data can be preserved with the photo form, is not easy to produce mistake.
The data analysis processing section, this part reads first calibration photo and pipeline photo, width in the record calibration photo between the two measuring arm again by the actual range between the two measuring arm in the input calibration photo, namely can be regarded as to get the conversion factor of size and actual, measured dimension in the calibration photo; After determining conversion factor, by the size of mark pipeline in practical photograph, can calculate the measurement size of pipeline; After calculating the measurement size of pipeline, compare by the built-in steel pipe caliber of data correction module and software series size and to revise, can draw the physical size of pipeline; Last input channel information, record are also preserved the data that record, and the while is generating tube track data table automatically, and data can be derived.Analyze and calculate pipe diameter by this data analysis processing section, can be so that the data that record to be accurate, statistics is convenient, and is easy to preserve, and therefore can reduce the generation of mistake.

Embodiment
As shown in Figure 1, pipe diameter measuring device based on photographic process, comprise survey instrument part and data analysis processing section, described survey instrument partly comprises crossbeam 1, gage beam 2, camera 3 and the standard metre bar 4 that is used for calibration, as shown in Figure 2, wherein camera 3 is installed on the crossbeam 1, and two gage beams 2 are parallel to each other and lay respectively at the both sides of camera 3, and two gage beams 2 and 1 vertical connection of crossbeam, the shooting direction of camera 3 and gage beam 2 to stretch out direction consistent; Described data analysis processing section comprises data correction module, analysis and control module and data memory module, carries out data between each module and transmits; The data analysis processing section is controlled camera 3 and is carried out data with the image storage unit of camera 3 and transmit, and simultaneously data analysis processing section operates to realize the input of steering order and the demonstration output of measurement data by the user.
