[Abstract]:The comprehensive parameter tester of buzzer is an intelligent instrument specially designed for the separation equipment of piezoelectric ceramic buzzer, which can directly display the resonant frequency and equivalent resistance value of piezoelectric ceramic buzzer. The instrument expands the function of the same kind of instrument, and the user can set the relevant parameters according to the need, at the same time, the equivalent resistance and resonant frequency can be separated by four qualified grades and the resonant frequency by three steps. The sorting results are displayed directly and output synchronously through the interface to facilitate the sorting of products. In this paper, the overall design scheme of the buzzer comprehensive parameter tester is given, the design of the hardware circuit of the system is described in detail, the design method and thought of the software system are described in detail. The reliability design and anti-interference technology used in hardware and software design of the system are summarized, the testing process of the system is explained through the debugging of the prototype, and the realization of the buzzer comprehensive parameter tester is verified by an example. The paper also summarizes the research work, finds out the shortcomings, and gives the direction of further research. This instrument adopts the principle of constant pressure method as stipulated in SJ2780-87 "General Technical conditions of piezoelectric Ceramics buzzer". After analyzing the function and principle of the testing device, the main components of the tester are put forward: constant voltage source, signal conditioning, "charge balance" type A / D integral, range selection, sorting interface, STC89C58RD single chip microcomputer circuit, etc. The software is mainly written in assembly language. This instrument has the characteristics of high testing speed, high precision, high stability, high reliability, visual display, simple operation, and all parameters are automatically measured and processed by the instrument. It is suitable for fast automatic test of buzzer on test equipment, and can also be used for quality inspection department. After the enterprise trial, the functional performance meets the design requirements and has been approved by the enterprise.
