The V1 + and V1- signals of FIG. 3 are directly connected to the MCU 110. The central control unit (MCU) 110 measures and calculates voltage values input to V1 + and V1-, Estimate the value.

Each of the pair of input power lines N and L is connected to a voltage input terminal of the central control unit (MCU) 110 via an inductor, a resistor and a capacitor in order to measure an input voltage.

Referring again to FIG. 3, the current measurement circuit block 140 among the hardware structures of the power measurement control adapter 100 will be described below.

An electronic device which uses a shunt resistor 142 mounted on one of the power output N and L lines of a household socket outlet and connected to I1 + and I1- of the central control unit (MCU) 110 at both ends of the shunt resistor 142 It has a function to measure the amount of current consumed by the product.

The voltage and current measurement block ESP430CE1B is included in the central control unit (MCU)

Referring to FIG. 5, a Bluetooth communication block is shown.

The Bluetooth module is used as communication means for transmitting the measured power value measured by the power measurement control adapter 100 to the user's smartphone T1. The Bluetooth module of the developed power measurement control adapter has a built-in Serial Protocol Profile in the Bluetooth module 112, and the UART communication is used in the central control unit (MCU) 110 of the power measurement control adapter 100 board, / RTI > Reference numeral 114 denotes a Bluetooth (BT) antenna.

The data format between the central control unit (MCU) 110 and the smartphone is described separately.

If you change the Bluetooth module in order to reduce the communication distance with the smart phone (T1) and the cost of the Bluetooth module, you should select the module that includes the serial profile protocol in the Bluetooth module.

The power supply / power supply control block will be described with reference to FIG.

The basic operation power of the IC parts such as the central control unit (MCU) 110 and the Bluetooth module 112 in the power measurement control adapter 100 board is 3.3 V and in the power measurement control adapter 100 board, (80V to 250V) as an input to the AC-DC converter 150 and generates a 5V power source. The 3.3V power source is obtained by using the LDO regulator 160 again. When an overload occurs in the electronic product E1 connected to the power measurement control adapter 100 board or when the temperature of the power measurement control adapter 100 board excessively rises, the central control unit (MCU) The power supply to the electronic product E1 is blocked by controlling the relay component 170 mounted on the control adapter 100 board.

And also functions to cut off or supply power to the used electronic product E1 according to the operation time set by the user.

The SW driver ported to the power measurement control adapter 100 is largely divided into three parts.

- main  driver

The main driver sets an ESP module in a central control unit (MCU) 110 for setting a main register value in the central control unit (MCU) 110 and measuring power when power is supplied to the power measurement control adapter 100. When the main register and the ESP module are set, the measurement start command is transmitted to the ESP module, and the central control unit (MCU) 110 enters the low power mode.

When the flag is changed by the ESP interrupt handler in the low power mode, the power measurement value saved by the ESP interrupt is changed to the unit of Watt that can be known by the user, and the cumulative power amount and the accumulated power amount in the unit of 30 minutes are stored in the flash memory, Calculate the temperature on the control adapter board.

In addition, when a predetermined time is reached according to the timer setting value designated by the user, the power measurement control adapter 100 functions to apply or cut off the power supply to the electronic product E1 connected thereto.

- ESP  Interrupt Handler

The ESP module is a power measurement module implemented as a one chip in a central control unit (MCU) 110 and performs power measurement according to a user-set environment setting value. The currently developed power measurement control adapter performs power measurement every 1 second based on the power frequency 60 Hz. When the ESP HW module completes the power measurement, it generates an interrupt to enable the ESP interrupt handler. The interrupt handler stores the measured result in the buffer and changes the flag to notify the main driver that the power measurement is completed.

- UART  Interrupt Handler

The power measurement control adapter 100 communicates with the user's smartphone T1 via the Bluetooth interface and the Bluetooth module 112 transmits data to and from the smartphone T1 via the central control unit . The communication protocol used at this time is the UART protocol. The UART of the central control unit (MCU) 110 generates an interrupt if there is received data in units of 1 byte, the UART interrupt handler stores the received data in the buffer, and when the predetermined message in communication format with the smart phone (T1) So that the central control unit (MCU) 110 can know that the received message has arrived.

Referring to FIG. 7, a software driver flow chart can be seen.

An interrupt handler is executed for ESP data and UART data processing, respectively. The driver starts the measurement and sets the central control unit 110 to the low power mode and the central control unit 110 receives the process measurement data and the process UART.

A single message can be sent up to three times, including all retransmissions. The control software assigns a serial number to the message to be transmitted. The drive generates a response message with the serial number of the message received by the control software. That is, the serial numbers of the request message and the response message must be the same. If the serial number of the received response message is not the same as that of the immediately preceding request message, the control software ignores the received message.
