The utility model relates to a sound reading device of a digital caliper, which consists of a joint 1, a data line 2, a data acquisition and conversion chip 3, a logic judgment chip 4, a voice chip 5, a D/A converter 6, a signal amplifier 7, and a loudspeaker 8. A battery 9 and a casing 10 are formed. The device collects data from the digital caliper interface and transmits it to the data acquisition and conversion chip 3. The chip 3 converts the data into decimal data and transmits it to the logic judgment chip 4. The chip 4 judges and processes the received value: it is a fixed value within a certain period of time. , the data is output to the voice chip 5; the data is not output in a continuously changing state; the chip 5 converts the data into a voice signal and outputs it to the D/A converter, and the D/A converter converts the digital signal into an analog signal and outputs it to the signal amplifier , the signal is amplified and output to the speaker for sound, and the system is powered by batteries. The scope of application of the digital caliper is expanded, and the visually impaired or blind can be used to improve the measurement speed, accuracy and efficiency.
Description
Technical field
The utility model relates to a kind of sound reading device of digital display calliper; Specifically application data collection conversion chip and logic determines chip are defined as the output data of digital display calliper measurement data and convert decimal data to; And be the device of analoging sound signal by speech chip, D/A conversion and loudspeaker etc. with digital data conversion, belong to field of measuring technique.
Background technology
Change in modern times in the production, measurement is a very important link.Modern manufacturing industry is to be based upon on the basis of standardization and interchangeability; Interchangeability means zero, parts must have certain precision; And precision measures out precision zero, parts that the height of measuring accuracy is directly connected to by survey instruments such as measurer, amount appearance.Because digital display calliper itself, in use have only when display panel could accurate reading during to the user.Therefore the user can't directly face display screen under a lot of situation, can't reading or owing to the vision reason causes reading error.The occasion that this external light is darker is used and user during as amblyopia or blind person, and reading is difficulty even can't reading relatively also, and misreads easily.Will cause like this measuring and deviation occurs and efficiency of measurement is low.
The utility model content
To above-mentioned deficiency, the utility model provides a kind of sound reading device of digital display calliper, has guaranteed the accuracy of measuring accuracy, has improved efficiency of measurement, and has enlarged the use occasion of digital display calliper, and be convenient to amblyope and blind person's use.
The utility model is realized through following technology:
A kind of sound reading device of digital display calliper, device is made up of joint 1, data line 2, data acquisition and conversion chip 3, logic determines chip 4, speech chip 5, D/A converter 6, signal amplifier 7, loudspeaker 8, battery 9, case 10 etc.Joint is inserted in the interface on the digital display calliper; Through data line 2 data are sent to data acquisition and conversion chip 3; Data acquisition, conversion chip 3 convert measurement data decimal system measurement data to and are sent to logic determines chip 4; The measurement numerical value of 4 pairs of receptions of logic determines chip carries out judgment processing: when data when in the regular hour scope when the steady state value, data are outputed to speech chip 5; When data are in continuous variable condition, output data not; Speech chip 5 outputs to D/A converter 6 after converting measurement data to voice signal; D/A converter outputs to signal amplifier 7 after digital signal is converted into simulating signal; After signal amplifier amplifies, output to loudspeaker 8, and send corresponding sound, system is by battery 9 power supplies.Except that joint, all other parts are installed in the case 10, and case is connected fixing with screw with the preset threaded hole in the digital display calliper vernier back side.
The sound reading device of this digital display calliper can improve the application scenario of digital display calliper greatly, makes crowds such as amblyopia or blind person can use digital display calliper, and improves measured speed and accuracy, increases work efficiency.
