Description

Technical Field

[0001] The utility model relates to the technical field related to electric energy meters, and in particular to an infrared start-up structure of an electric energy meter. Background Art

[0002] Existing smart energy meters require battery power to maintain the normal operation of their RTC real-time clocks before on-site installation or during a power outage. Therefore, reducing battery power consumption during this period of battery power supply is an important issue in the current design of smart energy meters. At present, the mainstream approach is to put the smart meter in a sleep state during the battery power supply period to reduce the overall power consumption of the system, and then wake up the system through external power-on and query buttons. This not only increases the complexity of the circuit, but also increases power consumption due to the need to maintain the system in a sleep state. Utility Model Content

[0015] In a preferred solution, one pin of the first transistor is connected to a third resistor, and the other pin is connected in parallel to a second diode and a fourth resistor.

[0016] In a preferred solution, a fifth resistor is connected in parallel to one side of the second transistor.

[0017] In a preferred solution, a sixth resistor and a third transistor are connected in series on one side of the first diode; and a seventh resistor is connected in parallel on one side of the third transistor.

[0031] Embodiment 1

[0032] Attached Figure 1 , 2 The utility model discloses an infrared power-on structure for an electric energy meter, comprising an electric energy meter body 1, an RTC real-time clock module 2, an infrared sensor 3 and a power-on locking module 4;

[0033] The electric energy meter body 1 is respectively connected to the RTC real-time clock module 2, the infrared sensor 3 and the power-on locking module 4, and supplies power to them;

[0034] The RTC real-time clock module 2 is used to track and record the current date and time of the electric energy meter body 1;

[0035] The infrared sensor 3 is used to detect whether an infrared signal is irradiated onto the electric energy meter body 1;

[0036] The power-on locking module 4 controls the power supply start of the electric energy meter body 1 according to the signal received by the infrared sensor 3;

[0037] The power-on locking module 4 is controlled by an infrared power-on circuit.

[0038] In order to prevent the use of the electric energy meter body 1 from being affected by a power outage of the external power supply, the power supply of the electric energy meter body 1 includes a power supply battery, and the power supply battery is used as a backup power supply.

[0039] In order to realize the operation of the power-on locking module 4, the infrared power-on circuit includes an LED lamp 5, a capacitor 6, a first resistor 7, a first transistor 8, a first diode 9, a second transistor 10 and a second resistor 11;

[0040] The LED lamp 5, the first resistor 7, the first transistor 8, the first diode 9, the second transistor 10 and the second resistor 11 are sequentially arranged in series;

[0041] The capacitor 6 is arranged in parallel on one side of the LED lamp 5;

[0042] The other end of the second resistor 11 is connected to the electric energy meter body 1 .

[0043] One pin of the first transistor 8 is connected to a third resistor 12 , and the other pin is connected in parallel to a second diode 13 and a fourth resistor 14 .

[0044] A fifth resistor 15 is connected in parallel to one side of the second transistor 10 .

[0045] A sixth resistor 16 and a third transistor 17 are connected in series on one side of the first diode 9 ; a seventh resistor 18 is connected in parallel on one side of the third transistor 17 .

[0046] The first resistor 7 is 2.4 kΩ; the second resistor 11 is 1 MΩ; the third resistor 12 is 100 kΩ; the fourth resistor 14 is 5.1 kΩ; the fifth resistor 15 is 10 kΩ; the sixth resistor 16 is 3 kΩ; and the seventh resistor 18 is 10 kΩ.

[0047] When the electric energy meter body 1 is powered by a battery, except for the infrared sensor 3 and the RTC real-time clock module 2, all other circuits of the system are closed. The infrared sensor 3 detects whether there is an infrared signal irradiating the electric energy meter body 1. When an infrared signal is detected, the infrared sensor 3 transmits the signal to the power-on locking module 4, controls the power management system of the electric energy meter body 1 to turn on the power, and starts the main functional modules of the equipment, so that the electric energy meter body 1 enters a normal working state.

[0048] An infrared power-on structure of an electric energy meter of the present application is designed with an electric energy meter body 1, an RTC real-time clock module 2, an infrared sensor 3 and a power-on locking module 4. Since the infrared sensor 3 sends a trigger signal only when it needs to be powered on and does not consume electric energy in the standby state, ultra-low power consumption is conveniently and simply achieved without additional hardware costs. By using the infrared sensor 3 as the power-on mechanism of the electric energy meter body 1, no additional hardware costs and additional circuit designs are required. This design also has high reliability. Since the infrared signal is used as the trigger signal, the problem of false triggering that may be caused by physical buttons is avoided. In addition, due to the working principle of the infrared sensor 3, it can work normally under various environmental conditions without the need for specific environmental conditions.
