资料介绍

智能水表为供水公司实时掌握用户用水情况和解决抄表困难问题提供了重要支撑,但传统的光电直读智能水表存在功耗高,电路复杂,体积庞大,长期稳定性差等问题;通过对水表关键技术研究分析,提出了一种基于三维矩阵电路读取字轮码盘的水表设计方案,它采用STM8L051超低功耗单片机为控制核心的分离式Mbus通讯电路设计思路,有效解决了智能水表功耗高和长期稳定性得不到保障问题,使智能水表小型化;实验数据表明,依据三维矩阵电路设计的光电直读智能水表通讯稳定,功耗低,采集效率高,长效工作稳定可靠。

Intelligent water meter provides an important support for water supply companies to grasp the situation of water users and solve the difficulty of meter reading.However,the traditional photoelectric direct reading intelligent water meter has many problems,such as high power consumption,complex circuit,huge volume,poor long-term stability and so on.Through the research and analysis of the key technology of water meter,a design scheme of water meter based on three-dimensional matrix circuit reading wheel code plate is put forward.It adopts the design idea of separated Mbus communication circuit with STM8 L051 ultra-low power consumption single chip microcomputer as the control core,which effectively solves the problems of high power consumption and long-term stability of intelligent water meter.The intelligent water meter is miniaturized.The experimental data show that the optoelectronic direct reading intelligent water meter designed according to the three-dimensional matrix circuit has stable communication,low power consumption,high acquisition efficiency and long-term stability and reliability.
