Research and application on a voice broadcast measure system;

Design of voice broadcast intelligent resistance measurement instrument based on singlechip;

The range finder voice broadcast feature.

The hardware takes two pieces of SPCE061A as the central proces- sors,which control collect and processing of the date,the dis- play,speech broadcast and other functions.

By using speech function of the Sunplus SPCE061A microprocessor and digital temperature sensor DS18B20, The system realized intelligent temperature gather, speech broadcast and temperature control function.

This paper introduce a multifunctional digital frequency meter with the function of voice prompt,which uses 16 bits single-chip computer SPCE061A produced by Sunplus as kernel components and FPGA technology.

It measures temperature,humidity,light intensity,concentration of harmful gas(including gas,cigarettes,alcohol) and other environmental parameters in real-time,with infrared remote control,liquid crystal display(LCD),voice broadcasting and real-time remind functions.

The structure Analogue weighting sensor + A/D converter + MCU + Voice chip + D/A converter + Speaker is basically adapted in the current electronic voice broadcast weighting systems in which the circuits are complex,the manufacturing costs high and the working reliability poor.
