数字量转4-20mA模拟量输出的模块设计

本论文介绍了数字量转4-20mA模拟量输出的模块设计方法。随着社会的不断进步和科学技术的迅猛发展,现代工业过程控制对仪器仪表装置在速度、精度、成本等方面提出了更高的要求,使用4-20 mA电流信号传输技术成为一种发展趋势。
为了提高单片机系统的抗干扰能力,看门狗己经成为系统中不可缺少的一员,在具体实施方面,设计者应综合考虑系统资源、经济性、可靠性等多方面因素,合理制定看门狗的控制方案,提高系统的性能价格比。
本设计采用低功耗低成本芯片,实现了低成本的复杂系统的设计。此技术可以应用到国民生产的各个领域,对于保证产品质量、提高生产效率、促进科学技术的发展等方面都具有重要的作用。

The digital quantity transfers the 4-20mA simulation quantity output the module design
The present paper introduced the digital quantity transfers the 4-20mA simulation quantity output the module design method. Along with society's unceasing progress and the science and technology swift and violent development, the modern industry process control to the instrument measuring appliance installment in aspect and so on speed, precision, cost proposed a higher request, uses 4-20 mA electric current signalling technology to become one kind of development tendency.
In order to enhance the monolithic integrated circuit system the antijamming ability, watch-dog oneself after becomes in the system essential, in the concrete implementation aspect, the designer should synthesize the consideration system resources, the efficiency reliably, and so on the various factor, reasonably formulates watch-dog's control plan, enhances the system the performance price ratio.
This design uses the low power loss low cost chip, has realized the low cost complex system design. This technology may apply each domain which produces to the national, regarding the guarantee product quality, the enhancement production efficiency, promotion science and technology aspect and so on development all has the vital role.
