[0022] At present, the display screens of common smart meters with screens and IoT smart meters on the market are always in a normally bright state, which invisibly increases the operating power consumption of the meters.

[0023] The patent with authorization announcement number CN206710480U and patent name "A low-power smart meter" introduces a low-power smart meter using an electronic ink screen. Although the electronic ink screen does not need to be powered when the displayed information is not changed, the effect of reducing energy consumption can be achieved. However, the meter in the patent still needs to update information periodically. When updating the information, the electronic ink screen needs to be powered, which increases power consumption.

[0024] Based on this, an exemplary embodiment of the present application provides a low-power IoT electric meter, which is provided with an electronic ink screen and an infrared sensing module. The infrared sensing module can monitor the surrounding working conditions. When a human body approaches, the infrared sensing module can detect the changes in infrared rays radiated by the human body and output a signal to the main control board. The main control board controls the ink screen to display real-time metering data. When the human body leaves the meter, the infrared sensing module can detect the changes in infrared rays radiated by the human body and output a signal to the main control board. The main control board controls the closing of the ink screen. In this way, the meter can control the display and closing of the ink screen according to whether someone is viewing the meter. When there is no one around, the ink screen is always in a closed state to reduce the power consumption of the meter.

[0025] An exemplary embodiment of the present application provides a low-power IoT electric meter, such as Figures 1 to 3As shown, the low-power IoT electric meter includes a housing 100, a cover plate is provided on the top of the housing 100, a wiring terminal 210 is provided at the lower end of the housing 100, and a main control board 201, a metering module 202, a display module 203, a storage module 205 and an infrared sensing module 204 are provided in the housing 100.

Compared with the currently used black and white LCD screen, the ink screen has lower power consumption and can display three colors of red, white and black, and can better display different types of information such as measurement, alarm, time, etc. The infrared sensing module 204 can monitor the surrounding working conditions. When a human body approaches, the infrared sensing module 204 can detect the changes in infrared rays radiated by the human body and output a signal to the main control board 201. The main control board 201 controls the ink screen to display real-time metering data. When the human body leaves the meter, the infrared sensing module 204 can detect the changes in infrared rays radiated by the human body and output a signal to the main control board 201. The main control board 201 controls to close the ink screen. In this way, the meter can control the display and closing of the ink screen according to whether someone is checking the meter. When there is no one around, the ink screen is always in a closed state to reduce the power consumption of the meter.

The current transformer is used to measure the power consumption of the user.

[0030] like Figure 4 As shown, during normal operation of the meter, the display screen is off by default, and the infrared sensing module 204 can detect in real time whether there is a person approaching; when a person approaches, the infrared sensing module 204 can detect the change of infrared rays radiated by the human body and output a signal to the main control board 201, and the main control board 201 can control the display screen to display real-time metering data; when the person leaves or the preset display time is reached, the main control board 201 controls the display screen to turn off and does not display content to save energy.

[0031] In one embodiment, the electric meter also includes a communication module 206, and the communication module 206 is disposed on the second partition 102, and the communication module 206 is electrically connected to the main control board 201. The communication module 206 communicates with the main control board 201 via SPI or UART, and the communication module 206 is used for the electric meter to communicate with the power host or other external devices. For example, communication can be achieved through carrier communication, Bluetooth, WiFi or 4G / 5G. In order to meet the needs of different scenarios, the communication module 206 can be a combination of one or more of the above communication methods. For example, the communication module 206 can be a Bluetooth or WiFi communication module or have both Bluetooth and WiFi communication modules. Electric power workers can remotely control the display and extinction of the display screen through the communication module 206. Figure 5 As shown, during normal operation of the meter, the display screen is off by default; when the communication module 206 receives an instruction for the display screen to display real-time data, the communication module 206 outputs the instruction to the main control board 201, and the main control board 201 controls the display screen to display real-time metering information; when the preset display time is reached, the main control board 201 controls the display screen to turn off to save energy.
