Operating procedure and operation principle:
Intelligent electric energy meter 1 described in the utility model is supervised from the anti-breaking method for electrically of electricity consumption dual power supply, process chip according to voltage
The Data Detection surveying device a7 and voltage monitor b feedback switches the power supply mode of electric energy meter 1.
Described intelligent electric energy meter 1 feeds back electricity from the anti-breaking method for electrically of electricity consumption dual power supply, voltage check device a to process chip
The numerical value in source, voltage check device b feeds back the magnitude of voltage of battery to control device, and process chip is generated by pulse generator and continues
The available pulse signal of electric apparatus coil, when not being connected to pulse signal, the normally opened contact of relay disconnects the coil of relay, connects
To after pulse signal, the normally opened contact of relay can close, method particularly includes:
(1) when power supply normal power supply, control device sends signal, electric energy meter to the coil of relay a9 and relay c8
1 power supply is directly connected to power supply, and accumulator a4 is also powered for electric energy meter 1 simultaneously；
(2) when voltage accumulator a4 is detected when electric energy meter 1 normal power supply but voltage check device b low to setting value
When, process chip sends signal to relay d5, and accumulator a4 and power on make accumulator a4 be electrically charged, voltage detecting
Device b detects accumulator a4 full of reaching after rated voltage, and process chip will stop sending signal to relay d5；
(3) when unexpected power failure, when the fed back values that process chip detects voltage check device a are 0, process chip is held
Continue and send signal to the coil of relay a9, and to relay while stopping stopping sending signal to the coil of relay c8
The coil of d5 sends signal, only retains seamless the powering for electric energy meter 1 of accumulator a4；
(4) when the electric quantity consumption of accumulator a4 is larger, when voltage falls to setting value, process chip is according to voltage check device
The data of a feedback stops sending signal to the coil of relay a9, and sends signal to the coil of relay b2 simultaneously, makes electric power storage
Pond b3 powers for electric energy meter 1；

Carry out the replacing of problem investigation and accumulator b3.
Described intelligent electric energy meter 1 has a power failure suddenly from the anti-breaking method for electrically of electricity consumption dual power supply, step (2) and restores electricity again
When, when process chip gets power up by voltage check device a and powers, process chip still keeps to relay a9
With the coil power supply of relay d5, the magnitude of voltage feeding back to process chip accumulator a4 up to voltage check device b reaches specified
During voltage, process chip continues to send signal to the coil of relay a9, and is stopping stopping sending to the coil of relay d5
While signal, the coil to relay c8 sends signal.After so that power up is powered, power supply charges first to accumulator a4, with
When power for electric energy meter 1, after accumulator a4 is fully charged, then switch to power supply directly power supply it is ensured that accumulator a4 has in real time
Electricity, even if can switch in next power-off.
From the anti-breaking method for electrically of electricity consumption dual power supply, step (3) is switched to after accumulator b3 powers described intelligent electric energy meter 1,
Power supply recovers again, when process chip gets power up by voltage check device a and powers, process chip stop to
While the coil of relay b2 stops sending signal, the coil to relay a9 and relay d5 sends signal, until voltage
When detection means b feeds back to the magnitude of voltage of process chip accumulator a4 and reaches rated voltage, process chip continues to relay a9
Coil send signal, and while stopping stopping sending signal to the coil of relay d5, the coil to relay c8 is sent out
Go out signal.
