摘要
介绍了一种新型电压监测仪的设计原理及软件流程图。采用FLASH型16位单片机(MSP430F149)作为微处理器,能方便地进行在线系统编程;3V系统设计,降低了装置的功耗;所选单片机内部资源丰富,集成度高,外围电路简单,使得装置体积进一步缩小;嵌入的GSM模块,可通过短信传送数据;增加的USB接口,方便了装置与PC机的数据交互。
This paper introduces a new instrument for voltage monitoring. The design and flow chart of its software is included. 16-bit RISC MSP430F149 acts as the MCU. There is 60 KB flash memory which is programmable online in system. Low supply voltage (3V) makes the instrument working with low power supply. With high integration of the chip and simple periphery, the instrument becomes smaller in size. GSM module is embedded in the instrument and it makes data transmission more easily. USB interface is also included to realize the communication between PC and the instrument.
