Abstract

The invention belongs to the heat meter technical field and relates to a low-power consumption intelligent ultrasonic heat meter. The low-power consumption intelligent ultrasonic heat meter includes an MCU as well as a liquid crystal display circuit, an infrared communication circuit, a button, a voltage conversion circuit, a voltage detection circuit, a valve, a time-to-digital converter and an MBUS communication circuit which are separately connected with the MCU; the time-to-digital converter is a TDC-GP21 time-to-digital converter; the time-to-digital converter is connected with a thermistor and an ultrasonic transducer. The EFM32TG840 and the TDC-GP21 both have the advantage of low power consumption, and therefore, the power consumption of the whole device is lower, the service life of the battery of the heat meter can be prolonged, and the demand cost of the whole heat meter for the battery can be decreased indirectly; and the TSS721A is a transceiver integrated chip for an instrument bus, and power demand of the TSS721A for a slave is not increased, and the bus can be connected in a non-polar manner, and background charging and management can be facilitated.

Description

technical field [0001] The invention relates to the technical field of heat meters, in particular to an intelligent ultrasonic heat meter with low power consumption. Background technique [0002] With the improvement of the quality of life and people's requirements for living comfort, building construction in northern my country will generally promote heat meters to households for heating supply in winter. Since 2009, heating reform has been carried out in northern my country, and it has achieved remarkable results so far. It is expected that billing by heat will be an important direction of heating reform in the north in the next few years. The heat meter is a key component in the heating system, which is responsible for the calculation, recording and data transmission of heat. Ultrasonic heat meters are gradually replacing mechanical heat meters and become the first choice for heating and heating metering solutions in the north because of their non-contact parts and high...
