Embodiment Construction

[0019] combine figure 2 , image 3 , Figure 4 The present invention is described further:

[0020] 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.

[0021] 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

A ultrasonic thickness gage with voice fetching function is used in non - destructive testing field, comprising principal machine and probe parts which is ultrasonic wave impulse transmitting unit and receiving unit and principal machine part consists of CPU, ultrasonic wave transmitting circuit, thickness wave forming circuit, counter circuit, display circuit and keyboard, with its properties: voice circuit and storage circuit both linked to CPU and USB general purpose serial bus interface circuit are added; USB interface circuit is consisted of USB interface integrated circuit with parallel bus and CPU linking together; CPU is used to receive signal sent by other circuits, and creates controlling signal to control them; CPU controls ultrasonic ultrasonic thickness circuit and calculates thickness value of object tested, the result can be shown or read by CPU controlling control voice circuit and put out by CPU to be stored in storage then uploaded to PU for data collection and analysis. It has excellent practicability.

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...
