Abstract: The present disclosure relates to a voltage measuring method, a computer device and a storage medium. The method includes: determining, by a voltage measuring device when the voltage measuring device is electrically coupled to a three-phase conductor through a voltage dividing capacitor in the voltage measuring device, a current measured voltage, the measured voltage being determined by measuring a voltage of the voltage dividing capacitor in the voltage measuring device; adjusting the coupling capacitances, and determining, by the voltage measuring device after the adjustment of the coupling capacitances, a current measured voltage; and determining, based on the measured voltage by the voltage measuring device before the adjustment of the coupling capacitances and the measured voltage by the voltage measuring device after the adjustment of the coupling capacitances, a voltage of a phase conductor of the three-phase conductor to be measured.

Abstract: A communication system, method, and device for a miniature intelligent sensor. The communication system includes a sensor, a power gateway, and a power Internet of things (IoT) server. The sensor is configured to obtain sensor data and send the sensor data to the power gateway according to a Bluetooth communication protocol. The power gateway is configured to receive the sensor data and perform protocol conversion on the sensor data to obtain protocol conversion data adapted to a message queuing telemetry transport (MQTT) protocol. The power gateway is configured to send the protocol conversion data to the power IoT server according to the MQTT protocol. The power IoT server is configured to receive the protocol conversion data and obtain server receiving data of the power IoT server according to the protocol conversion data.
