DDS155, single phase electric energy smart monitor is a fully digital energy consumption intelligent monitor developed by our company. It adopts MCU chip with high integration and high reliability. With the metering function of the electric energy meter, it can also monitor the electrical load, electricity consumption, grid voltage, grid frequency, ambient temperature, load current and load power consumption. And the related data is transmitted to the back-end server or the smart Internet cloud through WiFi, and the user understands and analyzes the power consumption through the mobile APP or a specific device.
The single phase electric energy smart monitor adopts 4P rail type installation, which is small in size, good in stability and high in measurement accuracy, it can be widely used in home, urban infrastructures. At the same time, Chinese new energy automobile industry is developing rapidly, and the charging pile industry is rising, this equipment fully meets the energy metering and volume requirements.
The DDS155 single phase electric energy smart monitor integrates the WIFI wireless module. The hardware integrates the MAC, the baseband chip, the RF transceiver unit, and the power amplifier; The built-in low-power operation mechanism can effectively realize the low-power operation of the module; Support the WiFi protocol and the TCP/IP protocol, and the users only need simple configuration to realize the networking function of the power monitor device to realize real-time data monitoring, cloud monitoring, and remote device control.
1. Main Functions and Features.
1.1 Energy monitoring
It can monitor active total energy, voltage, current, active power, reactive power, power factor, grid frequency and ambient temperature.
1.2 Wireless transmission medium: WiFi
The WiFi wireless transmission module is used as a medium for data transmission, integrated on the single-phase energy intelligent monitor PCB board, and with the home wireless WiFi or a specific WiFi device, the data is transmitted to the intelligent Internet cloud through the networked WiFi device, and the user passes Mobile apps or specific facilities to understand and analyze power usage.
1.3 data transmission mode: data transmission has active upload and passive reception
Active upload: The single-phase energy intelligent monitor can pack the important data that the user cares about and then send it out through the WiFi medium at a certain interval (default 3s, time can be set). (packaged data: active total energy, voltage, current, active power, reactive power, power factor, status word)
Passive reception: The background terminal can directly send a reading command to the single-phase energy intelligent monitor. The single-phase energy intelligent monitor passively transmits data, and the communication medium between them is also completed by WiFi.
1.4 WiFi Reset
In order to ensure the stable data transmission of the single phase electric energy smart monitor and prevent the WIFI module from transmitting the plunger, the timing hardware control reset is added, and the reset interval time can be set to be stable for a long time without failure and without maintenance.
5, energy metering
The single-phase energy intelligent monitor can accurately measure the active energy and display the power, voltage, current and current power from time to time.
