一种节省电量的超声波热量表的设计与实现

为了延长超声波热量表的使用周期,设计了一种能够自动降低功耗的超声波热量表。该设备采用智能测量频率技术,即根据检测到的流速情况调节检测频率,从而达到降低功耗,延长电池寿命的目的,此外还简单介绍了专门设计的数据采集模块、模数转换器、时钟模块和串口模块。

The Development of the Ultrasonic Heat Meter with Managing Electric Energy Function

It introduces the principle that the intelligent measurement frequency technology can change the measurement interval when the empty pipe in flow sensor（ or the heat carrier liquid is static for a long time）,presents a novel ultrasonic heat meter to automatically reduce power consumption. Reducing the test frequency can reduce the power consumption and extend the battery life. It describes the detail about data acquisition module,AD converter,clock module and a serial port module. The results show that the ultrasonic heat meter plays a key role in reducing energy consumption and the promotion of green environmental protection.
