Abstract
The utility model relates to a planeness measuring instrument for measuring the planeness of the surface of a measuring object. The planeness measuring instrument is composed of a small angle transducer, an electricity box and a connecting cable. Because a microcomputer minimum system is led in, the planeness measuring instrument can realize the integration of measuring and assessing; the measuring value on each measuring point can be automatically input, and various discriminating, correcting and processing are carried out by the microcomputer system. The measuring result can be immediately assessed and displayed according to the diagonal method or the rotary method. The utility model has the advantages of high speed, convenient operation, low cost and convenience for carrying. The planeness detection instrument is suitable for using in production fields and metrological services.
Description
The utility model belongs to non-electricity measure geometric sense amount instrument.
In the prior art, the measuring method of flatness mainly is to record angle of inclination value between each measuring point with level meter or electrolevel, manually evaluates calculating then.This measuring method data processing is complicated, time-consuming.The measuring system that applying electronic computing machine and electrolevel combine (measuring system that is combined by HP-85A computing machine and 432B-49 electrolevel as company of the United States Federal) is arranged in recent years, but cost an arm and a leg, volume is big, be unsuitable for the production scene and use.
The purpose of this utility model provides a kind of novel measurement of planeness instrument, to overcome the deficiencies in the prior art.
The utility model is made up of electronic box (1), low-angle sensor (2) and cable (3) as shown in Figure 1.Wherein electronic box (1) is by Z80CPU, 6KEPROM, 2KR,AM5 eight a hop count sign indicating number display, and the microcomputer minimum system that printer interface, 16 key boards are formed is partly formed in conjunction with analogue amplifier, analog to digital converter, stabilized voltage supply etc.(2) 1 of low-angle sensors, all can of resistance-type, condenser type or inductance type.
The utility model is worked under the special-purpose watchdog routine control of a cover, and all programs and form all are solidificated in the EPROM, therefore can measure once start.Low-angle sensor (2) places on the tested plane during measurement, and its electric quantity change is by in cable (3) the input electronic box (1), electric signal through analogue amplifier amplify and analog to digital converter convert digital quantity to after input microcomputer minimum system handle.Wherein the analogue amplifier input end has an analog switch that controlled by CPU, can make the input end swinging earth when automatic zero adjustment.Analog to digital converter is looked selected transducer range, can adopt 8 ADCO809 chip or 3 1/2 14433 chips, and stabilized voltage supply is directly by the 220V AC-powered.
The utility model is carried out finite point sampling pitch method and is measured on measuring method, divide diagonal line pattern and two kinds of patterns of layouting of closed grid pattern, choose on keyboard with the man-machine conversation mode, and insert data such as measuring point number and bridge plate length, by the pattern requirement of layouting sensor is shifted onto between each measuring point in turn then, instrument is promptly adopted into measured value automatically, and carries out various differentiations, correction and processing by microsystem, among the RAM that restores.Evaluate calculating with diagonal method or rotary process to depositing data in immediately after measuring end.At last, deliver to the microwriter printing by the nixie display display result or by printer interface.
Fig. 2 is the electronic box panel layout, and as shown in the figure, being provided with of keyboard is directly relevant with the function of instrument, and wherein " C " is that digital modifications key, " Z " are rotary process evaluation display key for diagonal method evaluation display key, " H ", and " ↓ " is execute key.
The utility model compared with prior art has the following advantages:
1. microcomputer minimum system and various electronics (device) element attach together in electronic box (1), make compact integral structure, and be cheap, easy to carry, is particularly suitable for the production scene and uses.
2. owing to introduce the microcomputer minimum system, make instrument have functions such as self diagnosis, automatic zero adjustment, sensor gamma correction, closed permissible error judgement, improved measuring accuracy, reduced requirement to sensor and analogue amplifier, and make the instrument reliable operation, easy and simple to handle, measuring speed is fast.
Claims (1)
1, a kind of instrument that is used for the Measuring Object surface planarity, it is characterized in that Z80CPU, EPROM, RAM, nixie display, keyboard, printer interface, analog to digital converter and other numerals and analog device attach together in electronic box [1], and be connected with low-angle sensor [2] with cable [3], form a complete surveying instrument.
