Abstract

The utility model provides a data collector of resiliometer which is a non-contact data collector matched with an instrument for non-destructive measurement of the strength of concrete in the construction industry. The utility model comprises a resiliometer shell, a guide rod, a calibration board and a slide block, wherein, a linear array CCD displacement sensor is arranged above the calibration board; a data signal output end of the linear array CCD displacement sensor is connected with a singlechip. The linear array CCD is converted through a photoelectric signal, and achieves one dimension scanning and signal output of a detected target; the size of the output signal of the CCD is proportional to the received light intensity; therefore, the slide block on the guide rod forms a wedge concave wave shape in the output signal of the linear array CCD, the signal is sent to the singlechip which only needs to calculate the number of element and the relative positions thereof occupied by the wedge concave wave shape in the output signal of the whole linear array CCD, and then whether the slide block moves and the relative displacement of the slide block can be received.

Description

The reisilometer data collector

Affiliated technical field

The utility model provides a kind of reisilometer data collector, and particularly a kind of non-contact data harvester belongs to a kind of data collector of matching with the instrument of noninvasive measurement concrete strength of being used in the building trade.

Background technology

The direct-reading reisilometer has been widely used in measuring concrete intensity at present, write down each measuring point acts on sliding block resilience on the reisilometer guide rod when ram hammer maximal value, on request each concrete is surveyed part and will survey 10 districts, each is surveyed the district will select 16 measuring points, workload of data collection is very heavy, inefficiency, and make mistakes easily.For addressing this problem, it is that " 88210311.3 " name is called the technology appearance of " concrete crushing strength instrument for evaluating " that the patent No. is arranged, its technical scheme is that slide potentiometer is installed on reisilometer, the sliding reed of this slide potentiometer and the pointer of reisilometer combine as a whole, the axial reisilometer needle pivot of potentiometer resistance wire coil is installed, and the simulating signal extension line of slide potentiometer connects computing machine.This technical scheme has had very big progress than the collecting method of direct-reading reisilometer, has reduced workload effectively.But, because the slide potentiometer that it has adopted the pointer of sliding reed and reisilometer to combine as a whole, and reed length service time one of slide potentiometer will be become flexible, increased the resistance of former reisilometer slide block, cause bigger systematic error, cause the signal of being defeated by computing machine inaccurate, gather the data distortion.Because being hit, slide block carries out damped motion after the collision in addition, so the reed life-span of slide potentiometer is limited.For addressing these problems, state architectural design research institute is in the utility model patent of having applied for " reisilometer of band electron showing value device ", the patent No. is " 01220127.8 ", the principle of this technology is by measuring the time of slide block by length-specific more than two sections, and the applied acceleration computing formula calculates its displacement.But requiring the friction force whole process between slide block and the guide rod must be desired constant, accomplishes and be difficult to control in the actual manufacture process, thereby has certain error, even if proofread and correct but because its discreteness also must all will be carried out its poor practicability at every turn.

Summary of the invention

The purpose of this utility model is to provide a kind of and the matching used non-contact data harvester of reisilometer, the data accuracy rate height that this data collector is simple to operate, systematic error is very little, gather, and the good stability of system is practical.

The purpose of this utility model is finished by following technical proposals: this reisilometer data collector comprises resiliometer casing, guide rod, scaleplate, slide block, the line array CCD displacement transducer that one length in pixels is no less than 20mm is housed above scaleplate, the data output signal of line array CCD displacement transducer flows to portable monolithic machine system and handles, shows and store, Single Chip Microcomputer (SCM) system links to each other with computing machine by USB interface, the data transfer of storage can be pass by, computing machine according to the relevant standard of country calculate, the form processing.

Principle of work of the present utility model is as follows: when the slide block on the reisilometer guide rod is hit motion, the line array CCD displacement transducer that is equipped with above scaleplate is changed by photosignal, realization is to measured target (slide block that is hit on the guide rod) one-dimensional scanning and signal output, because the size of CCD displacement transducer output signal is directly proportional with the institute receiving light power, video part pixel output signal voltage amplitude is less, and non-video part pixel output signal voltage amplitude is bigger.Therefore, slide block on the guide rod forms a wedge shape depression waveform in the output signal of line array CCD, this signal is defeated by single-chip microcomputer, as long as single-chip microcomputer counts wedge shape depression waveform shared unit number and relative position thereof in the output signal of whole line array CCD, whether the position that just can draw slide block has taken place to move and relative shift, single-chip microcomputer is stored in this result in the code specified memory territory, and show shift value, single-chip microcomputer passes through USB interface, can give computing machine data transfer easily whenever and wherever possible, according to country, industry or user, data processing is carried out in requirement, form printings etc. form concrete strength " survey report " form of standard.

Reisilometer data collector provided by the utility model has following advantage:

1, because the data acquisition parts do not contact with the unit under test of reisilometer, do not increase any resistance of reisilometer slide block, kept the measuring accuracy of former reisilometer constant.

2, the data of Cai Jiing are accurate, and measuring accuracy can reach micron order, and the good stability of system, long service life.

3, installation, easy to use, the user can install and use the notebook data harvester on any reisilometer, once revise when the single-chip microcomputer display processing system only needs just dress, calibrate the displacement of being measured and get final product, the user can self-correcting, practical, therefore also saved cost of use and maintenance cost for the user.
