The following is a description of the operation principle and functions of the various blocks of the creation, such as the circuit diagram of the creation shown in the fifth and sixth figures. According to the AC-DC power supply circuit 41 of the fifth figure, JP1 is the live line of the socket (L). The input point, JP2 is the input point of the negative line (N) of the socket, JP3 is the input point of the socket ground (G), R1 and R3 take the AC power from the fire line P1, C2 and MOV1 are the power noise filtering and bursting For wave absorption protection, after D1 rectification, L1 and C4 are again composed of filter and DC high voltage power storage. U1 is AC to DC switching regulator IC. The ratio of resistance values of R2 and R5 can be used to obtain U1 turn. The voltage value of 6.3V DC is stored on C5. In the fifth figure, D2, D3, C1 and L2 are the necessary parts for the conversion IC U1. U3 is a linear regulator IC, which can stabilize the output. The 5V operating voltage is fixed for use by other parties, while C6, C7 and D4 reconfirm the 5V voltage regulation, while 6.3V is used to provide the relay K1 of the zero-crossing relay (RELAY) control circuit 42.

The zero-crossing relay (RELAY) control circuit 42 is mainly used to make a zero-crossing relay (RELAY) control, which is to ensure that when the contact of the switching relay is connected, there must be no voltage at both ends of the current contact, that is, what we call " At the time of zero crossing, the power supply can be connected to the load, or the power supply can be cut off from the load. The so-called load here is the electrical appliance plugged into the socket to make the power supply start the surge. The current limit starts at the minimum and no spark is generated. At the same time, it is also ensured that the power is turned off when the power is turned off and at the lowest voltage.

In the fifth figure, JP5 and JP6 are the sockets of the creation. The plug of the electrical appliance is inserted between JP5 and JP6. In the figure, TR1 and relay (RELAY) 1 are the power control signals from the MCU control circuit 44 microprocessor. The relay K1 is controlled by the relay (RELAY) 1 signal, the triac Q2 is controlled by the TR1 signal, and the mechanical contacts of K1 and the semiconductor contacts of the Q2 controller (Triac) are connected together. Therefore, through the timing of TR1 and relay (RELAY) 1, that is, the context of the action can achieve the above purpose, as explained below: when the power is put into the socket, first make TR1 HI, and turn on through R22 and Q3. The U5 zero-crossing control IC will also conduct when the current AC voltage (ie, both ends of the K1 contact) is zero, triggering the Q2 controller (Triac) to conduct during the zero-crossing period (approximately 1V of voltage drop) In other words, the voltage of JP5 will be fully charged from the zero degree of the AC sine wave type. After 20msec, relay The RELAY 1 signal also becomes HI. After R23, Q4 is turned on, and the relay of K1 is operated to make the mechanical contact of K1 closed. At this time, the Q2 controller is completely short-circuited at both ends, and the 1V voltage is turned on on the controller. Drop, also becomes 0V, after 200msec (make sure the relay contacts have been closed stably), then the TR1 signal becomes LOW, and Q3, U5 and Q2 are turned off. At this time, the power of the K1 is separately supplied to the load.

When the power supply is cut off from the socket: first make TR1 HI, let Q3, U5 and Q2 turn on. After 20msec, make relay (RELAY) 1 LOW, turn off Q4 and K1, after 100msec (make sure the relay contacts are stable) Then, let TR1 be LOW, and let Q3, U5 and Q2 be turned off. At this time, Q2矽 control will turn off the power during zero crossing. In the figure, R7 and C10 provide a 6.3V DC power supply for the K1 coil, which allows K1 to have enough power to make K1 generate suction when it is ON, and when it is sucked, the voltage will drop, so that K1 can save power.

The above measuring and converting circuit 43 mainly measures two signals, such as a power supply voltage and a consumed current, and the power supply voltage is from P1, and is divided by R8, R9 and R20, that is, the voltage signal of R20, which is proportional to the power supply. The voltage of P1, and the current of the socket will return to the negative terminal (N) of the plug via R17, which is P2 in the figure, so the voltage across R17 (very small resistance value, such as 1mΩ) is measured, that is, proportional to the current The current consumed by the load, R13, R14 in the figure is to measure the small voltage signal at both ends of R17 to the measuring IC U4, the power of U4 is from Q1, and the MCU control circuit 44 can control the ON and OFF of Q1 to provide Or cut off the U4 working power supply, U4 can directly measure the above voltage signal, and current signal, and the conversion can be extended to derive power, frequency, power factor and accumulated real power and virtual work and other power information.

In the figure, X1 is a quartz oscillator. With C17 and C18, the working time base signal required by U4 can be generated. At the same time, signals such as digital control signals SI, SO, SCK, ADE-CS and IRQ and MCU control circuit 44 micro processing IC are provided. The U2 connection control, in other words, the U2 processor IC commands and controls the U4 power measurement IC through these control signal lines, and reads various power information, and stores it in the memory inside U2.

As shown in the sixth figure, the MCU control circuit of the MCU control circuit 44 has a microprocessor IC U2 and includes a program, a memory, a control interface, a communication interface, etc., and the power source thereof is from the AC-DC power supply circuit 41. 5V, controlled by control line TR1 and relay (RELAY) 1, zero-crossing relay (RELAY) control circuit 42, to achieve zero-crossing non-sparking power ON and OFF control, in the sixth figure, T1 is the thermistor It is installed near P2 and the negative pole (N) of the plug. If there is poor contact, the temperature will rise and the lower resistance will be reduced. When the threshold is exceeded, the power relay (RELAY) will be turned off actively to ensure safety. . Through the above mentioned SI, SO, SCK, ADE-CA and IRQ signals, the self-measurement and conversion circuit 43 obtains the current power data, and stores the data in the memory inside U2 itself, and can also borrow The LED light number display and the two key switch states on the key reading circuit 45 are read by KEY1 and KEY2, responding to the requirements of the panel operation. On the other hand, through the five signal lines of LEDC1~LEDC5, five different color LEDs are controlled and combined into a strip shape, which can be individually or collectively lit, or the PWM wavelength ratio can be used to adjust the brightness of the LED. LED C6, LED C7 control line, corresponding to the KEY1 and KEY2 message indication. Finally, U4 can also be converted to Zigbee via the Zigbee communication circuit 46 via the RXD-IN and TXD-OUT signal lines. The wireless signal is connected to an external control platform, and the measurement data is returned and controlled and controlled by the control platform. In the figure, J1 is the U2 program burning interface, by which the content of the U2 internal execution program can be modified.

The LED signal display and button reading circuit 45 is the operation interface of the creation, including three buttons and eight LED indicators. For example, in the sixth figure, the SW1 system is designed to be used as a Zigbee network connection button, that is, when it is used for the first time. At the same time, it must be paired with the control platform (such as Gateway). For example, if the control platform is turned on and the pairing is enabled, then SW1 is pressed, and the SW1 signal informs the Zigbee of the Zigbee communication circuit 46 via the ZB-KEY signal line. The module IC U7 performs the pairing work, so that the creation and control platform completes the networking operation. If the connection is successful, the LD8 corresponding to the LED under this button will light up and continue, if the receiving signal is bad, the signal is broken. The indicator will flash.

In addition, SW2 is the power control button. When each press, the power supply status of the power socket is changed. In the sixth figure, the LED corresponding to the button is lit (electrically) or extinguished (powered off). .

In addition, SW3 is a timing function button. The timing function can be set to be turned on or off from the control platform. It can also be directly operated on this creation. Each time the button is pressed, the conversion timing function is turned on or off. At the same time, the corresponding LD4 is turned on or off to indicate that the timing function is turned on or off.

In the sixth picture, there are finally 5 LEDs, LD1 (green), LD2 (yellow-green), LD3 (yellow), LD4 (red-yellow), and LD5 (red). Take this creation as an example. LD1~LD5 respectively represent 50W, 200W, 500W, 1000W and 1500W, and one of the LEDs lights up in time to represent the overload tripping power set at the moment. If 1000W is set, then point Bright LD4, after 2 seconds, alternately illuminate 0~5 LEDs from LD1 for 3 seconds. In other words, this creation will measure the power value of LD1, LD2, LD3 and LD4 by about 60% according to the current measured power value, for example, 800W [800W-500W=300W, 300W/(1000-500)W= 60%], Yuyi, if the measured value is 1200W, LD4 is fully bright, and also makes LD5 light about 40% brightness [1200W-1000W=200W, 200W/(1500-1000)W=40%] However, because it exceeds the set 1000W, after a few seconds, it will trip, that is, the power relay (RELAY) is cut off, so that the socket power supply is turned off to ensure safety. At this time, LD4 will flash, indicating that it is in the overload protection trip state until Re-press the power switch or release it by the control platform.

In the sixth figure, the Zigbee communication circuit 46 is the communication interface of the creation of the external control platform. The internal control is mainly controlled by the Zigbee module ICU7. Since the power supply of the module is 3.3V, the U6 regulator IC is designed. , from the 5V to obtain a stable 3.3V supply U7.

In the figure, J2 is the U7 program burning interface, by which the content of the U7 internal execution program can be changed. In addition, U7 communicates with the MCU control circuit 44 by the two communication signal lines of RXD-IN and TXD-OUT. In other words, U7 converts the communication signal of U2 to the external control platform from the digital logic signal into The radio wave is converted into a logic signal by the Zigbee module of the control platform to achieve the purpose of wireless connection.

The disclosures of the above embodiments are merely illustrative of the main techniques of the present invention, and are not intended to limit the technical scope of the present invention, and should be considered as a simple application or an easy change or replacement based on the prior art. The technical scope of the case is reasonable.
