[0055] As shown in Figure 1 the metering system metering design circuit Figure OneIn one embodiment, the power supply part circuit includes: when the mains power supply, the system power VMCU is provided by VCC_5V of the mains, and when the power supply is off, the system power VMCU is automatically switched to be provided by the battery VBAT_IN because the voltage of VCC_5V is 0; the power failure detection part circuit includes: when the mains power supply, the voltage value of VHH is 12V, and after being divided, the voltage is connected to the LVD detection pin of the anti-theft power monitoring MCU including the SOC chip; the SOC chip identifies that the current is in the mains state; when the power supply is off, the voltage of VHH rapidly drops to 0V, the LVD detection pin has no voltage value, the system is identified as the power failure state, and enters the low-power consumption mode; the anti-theft power monitoring MCU system main chip circuit includes: the chip is an integrated SOC chip, and a high-precision low-power consumption metering module EMU is integrated in the chip, which provides the system with operation ability and metering sampling ability; compared with the separated MCU+metering chip mode, the chip scheme can better reduce the power consumption of the power failure metering and save the hardware cost; the metering sampling part circuit includes: the voltage sampling circuit is input to the V1+ sampling channel of the SOC chip for signal analysis after the voltage signal is scaled by the voltage dividing resistor; the live wire current sampling circuit is input to the I1- and I1+ sampling channels of the SOC chip for current signal analysis after the signal is scaled by the manganese copper shunt; the zero line current sampling circuit is input to the I2+ sampling channel of the SOC chip for current signal analysis after the signal is scaled by the current transformer;

[0056] The operation logic of the electric energy metering system includes: when the mains power supply is off, the system circuit detects that the voltage of VHH is reduced to the threshold of the power failure detection register in the SOC chip, and the system enters the low-power consumption mode; when the metering time granularity Tm is equal to 0, it indicates that the system is in the low-power consumption high-precision metering mode, the metering module EMU of the SOC chip is configured in the low-power consumption working mode (including the 32KHZ working frequency mode) and continuously metered; when the metering time granularity Tm is not equal to 0, the SOC chip is configured to be woken up according to the metering time granularity Tm, at this time, the main frequency of the SOC chip uses the low-frequency mode of the low-power consumption working mode, and the metering module EMU is configured in the low-power consumption working mode, the values of the live wire current and the zero line current are sampled by the EMU, the EMU module is turned off, and the SOC chip enters the Sleep super low-power consumption sleep mode;

[0057] The system power consumption Psys is metered according to the following formula:

[0058] If the metering time granularity Tm=0, Psys=Prun; (Prun is the low-power consumption metering mode of the SOC chip);

[0063] If the maximum voltage Umax is not equal to 0,

[0064] If the maximum voltage Umax is equal to 0,

[0065] When Ib(t)>Ia(t):

[0066] If the maximum voltage Umax is not equal to 0,

[0067] If the maximum voltage Umax is equal to 0,

[0068] Wherein, Un is the working voltage; if the live line metering channel current Ia(t)< the zero line metering channel current Ib(t), and the zero line metering channel current Ib(t)< the starting current Is(t): no electric energy metering is performed; through the system power consumption Psys metering formula and the electric energy Energy metering formula operation, the smaller the metering time granularity Tm is, the longer the time that the electric meter is in the low-power metering mode is; the more continuous the sampling time of the metering channel is, the more accurate the accuracy is, and at the same time, the power consumption is also greater, so that the accuracy and power consumption adjustment effect is realized.

[0093] As shown in Figure 1 the metering system metering design circuit Figure OneIn one embodiment, the power supply part circuit includes: when the mains power supply, the system power VMCU is provided by VCC_5V of the mains, and when the power supply is off, the system power VMCU is automatically switched to be provided by the battery VBAT_IN because the voltage of VCC_5V is 0; the power failure detection part circuit includes: when the mains power supply, the voltage value of VHH is 12V, and after being divided, the voltage is connected to the LVD detection pin of the anti-theft power monitoring MCU including the SOC chip; the SOC chip identifies that the current is in the mains state; when the power supply is off, the voltage of VHH rapidly drops to 0V, the LVD detection pin has no voltage value, the system is identified as the power failure state, and enters the low-power consumption mode; the anti-theft power monitoring MCU system main chip circuit includes: the chip is an integrated SOC chip, and a high-precision low-power consumption metering module EMU is integrated in the chip, which provides the system with operation ability and metering sampling ability; compared with the separated MCU+metering chip mode, the chip scheme can better reduce the power consumption of the power failure metering and save the hardware cost; the metering sampling part circuit includes: the voltage sampling circuit is input to the V1+ sampling channel of the SOC chip for signal analysis after the voltage signal is scaled by the voltage dividing resistor; the live wire current sampling circuit is input to the I1- and I1+ sampling channels of the SOC chip for current signal analysis after the signal is scaled by the manganese copper shunt; the zero line current sampling circuit is input to the I2+ sampling channel of the SOC chip for current signal analysis after the signal is scaled by the current transformer;

[0095] The system power consumption Psys metering formula is as follows:

[0096] If the metering time granularity Tm=0, Psys=Prun; (Prun is the low-power consumption metering mode of the SOC chip);

[0104] If the maximum voltage Umax is not equal to 0,

[0105] If the maximum voltage Umax is equal to 0,

[0106] Wherein, Un is the working voltage; if the live line metering channel current Ia(t)< the zero line metering channel current Ib(t), and the zero line metering channel current Ib(t)< the starting current Is(t): no electric energy metering is performed; through the system power consumption Psys metering formula and the electric energy Energy metering formula operation, the smaller the metering time granularity Tm is, the longer the time that the electric meter is in the low-power metering mode is; the more continuous the sampling time of the metering channel is, the more accurate the accuracy is, and at the same time, the power consumption is also greater, so that the accuracy and power consumption adjustment effect is realized.
