MICROCONTROLLER STAND FOR STUDYING AND RESEARCHING THE OPERATION ALGORITHMS OF SMART ELECTRICITY METERS Russian patent published in 2022 - IPC G09B23/18 G06F3/14 

FIELD: electrical engineering.

SUBSTANCE: invention relates to the field of electrical engineering, electronics and radio engineering and can be used for educational laboratory work and scientific research in this area. The microcontroller stand for studying and researching the algorithms of the SEM operation contains: computer 1, the first MCU 2, the second MCU 3, the third MCU 4, the first DAC 5, the second DAC 6, the programmer 7, the display unit 8, the fourth MCU 9, the signal generator 10 (two-channel), the first radio module 11, the second radio module 12. The signal generator 10 is a signal generator of various forms and is intended for specialists who calibrate instrumentation. Radio modules 11 and 12 ISM ranges are produced by many companies. Computer 1 is connected via digital interfaces, such as USB interface, to the first MCU 2, the second MCU 3, the third MCU 4 and the fourth MCU 9. The first DAC 5 and the second DAC 6 are connected to the digital outputs of the first MCU 2 and the second MCU 3, respectively. the outputs of which are connected, respectively, to the first and second inputs of the multichannel ADC built into the microcontroller of the third MCU 4, the digital outputs of the third MCU 4 are connected to the display unit 8. The output of the programmer is equipped with a connector that allows it to be connected to the programming inputs of any of the four MCUs, digital output the first MKU 2 is connected to the digital input of the fourth MKU 5 and is designed to synchronize the operation of these MKU. The first MCU 2 and the second MCU 3, as well as the two-channel signal generator 10 are designed to generate signals that simulate the signals of voltage and current sensors. The third MKU 4 is designed to simulate the microprocessor core of the SEM. The first 11 and second 12 radio modules, as well as the fourth MCU 5 are designed to exchange information or, in the simplest case, only to transfer the results of information processing from the third MCU 4 via the ISM radio channel to the fourth MCU 5, which is designed to simulate a data collection device from the ISEE.

EFFECT: expansion of functionality that allows you to study and explore the algorithms of modern smart electricity meters (SEM) and data exchange using microcontroller-controlled radio modules ISM ranges.
