Description of the Invention The present invention pertains to water meters and thermal energy meters, and more particularly to a method of signal transmission and calculation of a vortex electronic water meter and a thermal energy meter.
BACKGROUND OF THE INVENTION Currently, most of the large-diameter and small-caliber smart water meters and heat energy meters used in various places are manufactured using mechanical transmission or ultrasonic waves, and the measurement is based on rotating gears meshing to form decimal and periodical launches. Ultrasonic signals to achieve the purpose of measurement, the structure of these tables are more complex, or measurement accuracy is low, or measurement of low flow sensitivity is not enough.
Summary of the Invention In order to solve the above problems, the invention provides a solution which can make the structure of the smart water meter and the heat energy meter simple and reliable, and the measurement accuracy is greatly improved. 
The invention is realized by incorporating one or more vortex meter movements made of metal or non-metal into a cylindrical case body made of metal or non-metal. The core is embedded in one or more rotating shaft bases and rotating shaft rings made of wear-resistant material in the center of the two rectifying brackets. The rotating shaft ring has an inverted cone shape for the inner hole and is installed in the middle of two rectifying brackets. One or more signal-trigger magnets or metal sheets are fixed to a plurality of blades of a turbine.
When tap water flows through the inventive device, the kinetic energy of the tap water will drive the turbine to rotate, and the signal triggering magnet fixed on the turbine blade will periodically trigger the magneto-sensitive element fixed in the empty pipe joint, and the magneto-sensitive element will The electric pulse signal is sent out to the outside and a circuit controller composed of a computer chip (MCU) uses the pulse signals to calculate the amount of water flowing through the device represented by each pulse signal, and the flow represented by each pulse signal is generated. The accumulated amount of tap water of the present invention is the cumulative amount of tap water to be metered by the invention.
When the invention is in use, when there is water or other liquid flowing through the present invention, the turbine of the inner movement of the invention can measure the rotation of the turbine or rotate a certain degree each time it rotates or turns a certain angle. The time required, and the time required for the rotation of the turbine or a certain angle to be measured is recorded in the memory of the microcontroller (MCU) and replaced with the memory stored in the microcontroller (MCU) last time. The time, then, through the MCU chip of the present invention, the amount of fluid measured during each rotation or rotation of a specified angle of the stored turbine can be found from the base table data memory.
