Embodiment Construction

[0016] combine figure 2 , image 3 , Figure 4 The present invention is described further:

[0017] A new type of ultrasonic thickness gauge with voice reading function, which consists of two parts: a host and a probe. The probe part is divided into an ultrasonic pulse transmitting probe and an ultrasonic pulse receiving probe; the host part is composed of a CPU central processing unit, a power conversion circuit, an ultrasonic thickness measuring circuit, a voice circuit, a memory circuit, and a USB universal serial bus interface circuit.

[0018] The CPU central processing unit U5 is a 51 series single-chip microcomputer of ATMEL Company, and the model is AT89C51. The 8 pins P0.0~P0.7 of the P0 port are used as the data bus of the entire system, and at the same time pass through the address latch U6, the model is 74LS373, and the 74LS373 is output through the ALE pin during off-chip addressing, and the latch The addresses P0.0-P0.7 are used as the lower 8 bits A0-A7 of ...

Abstract

An ultrasonic thickness gauge with voice reading function is used in the field of non-destructive testing. It includes two parts, the host and the probe. The probe part is the ultrasonic pulse transmitting unit and the receiving unit. The host part includes a CPU, an ultrasonic transmitting circuit, a signal receiving and amplifying circuit, a thickness wave forming circuit, a memory circuit, a counter circuit, a display circuit and a keyboard. , memory circuit is used for storing thickness value, is characterized in that: also be provided with the voice circuit that is connected with CPU, USB universal serial bus interface circuit; USB interface circuit is made up of the USB interface integrated circuit with parallel bus and CPU connection, voice circuit It is used to realize the voice reporting; the CPU controls the ultrasonic thickness measuring circuit, and the thickness value of the measured object is obtained through calculation and processing, which can be displayed, and the measurement data can also be read out by the CPU controlling the voice circuit. All measurement data are finally uploaded to the PC through the USB interface for data analysis and collection. The instrument is practical.

Description

technical field [0001] "An ultrasonic thickness gauge with voice reading function" is an ultrasonic thickness measuring instrument with voice pronunciation reading and storage functions of measurement data, which can be widely used in the field of non-destructive testing. Background technique [0002] Ultrasonic thickness measurement is a mature inspection technology in the industrial field. Its biggest advantages are safety, convenience, reliability, accuracy and high precision during detection. Such as figure 1 As shown in the structural block diagram of the existing ultrasonic thickness gauges at home and abroad, the current ultrasonic thickness gauges at home and abroad are mainly composed of two parts: the host and the probe. The host circuit includes an ultrasonic transmitting circuit, an ultrasonic signal receiving and amplifying circuit, a thickness wave forming circuit, a counter circuit, a liquid crystal display circuit and a keyboard. When working, the high-volt...
