It is necessary to realize the 1/2 blanking when designing the 4-1/2 digital voltmeter based on ICL7135 chip. The traditional digital voltmeter meters achieve the function by using the single-chip microcomputer program control. A new design should be considered when circuits are designed without the single-chip microcomputer. This paper combines the blanking terminal of the CD4511 decoding chip with the output signal of the A/D chip to design a complex logic gate circuit for realizing the blanking function. Experiment has been done to verify that the design of the complex logic gate circuit is feasible and it can guarantee the realization of the 1/2 blanking.

The thesis presents a set of design scheme of grating displacement measuring system by taking SCM (Single Chip Microcomputer) as the core component. It describes the system design principle and the design process of software and hardware in details, i.e. realizing standard TTL level signal output through the processing of grating output signal amplification, sub-dividing, modulation and driving, so that grating output signal could match the numerical control system. It turns out that the designed grating displacement measuring system is able to satisfy the requirement of high-speed sampling and storage and feasible to be used for the measurement of actual grating displacement. The system has a simple and compact structure and a lower price, and owns favorable practical performance.

The display of ordinary voltmeter is not clear enough, the measurement range is narrow and the anti-interference ability is weak. This paper studies the design and Simulation of voltage measurement system based on ADC0809. Combined with the actual production situation, using the function that ADC0809 has 8 analog inputs and can convert the analog input into digital display, this paper designs the circuit with single chip microcomputer chip AT89S51. Combined with the working principle of a / D converter and DC digital voltmeter composed of them, the voltage measurement of 0-10V is realized in this paper. The experimental results show that the measurement system has the advantages of accurate reading, wide measurement range and micro power consumption.
