Embodiment 1
The embodiment of the present invention provides a kind of control intelligent electric energy meter closing switch method, as shown in Figure 1, it is long-range to can be applied to user
The scene for manipulating the combined floodgate of intelligent electric meter, as shown in Fig. 2, this method comprises the following steps：
Step S1：Judge whether the relay of intelligent electric meter is off.
In the embodiment of the present invention, when intelligent electric energy meter close a floodgate allow in the case of, i.e., in the case where relay disconnects,
It could carry out subsequent detection.In circuit as shown in Figure 3, K1 is relay, and U9 is relay driving chip, in the present embodiment
The chip model used is WS4680QE, but is not limited thereto.MCU (Microcontroller Unit, microcontroller)
Relay disconnection and closure are controlled by operating U9.
Step S2：When the relay of intelligent electric energy meter is off, the outlet voltage value of relay is obtained.
In the embodiment of the present invention, circuit as shown in Figure 3, inductance L1, resistance R36, R37, R38, R39, R40, R41, R43
And capacitance C42 forms front end resistor voltage divider circuit, carrying out partial pressure to the inlet wire terminal voltage of relay gives MCU progress AD samplings.
Resistance R51, R52, R53, R54, R26, R23 and capacitance C100 form rear end resistor voltage divider circuit, by the leading-out terminal electricity of relay
Pressure carries out partial pressure and gives MCU and sampled.MCU is sampled according to the end of incoming cables sample voltage value of relay and the leading-out terminal of relay
Voltage value calculates the outlet voltage value of true relay.
Step S3：Judge that the user being connected with relay whether there is according to outlet voltage value and predetermined voltage threshold
Power generation behavior.As shown in figure 4, step S3 is specifically included：
Step S31：Judge whether leading-out terminal voltage value is more than predetermined voltage threshold.
In the embodiment of the present invention, by the way that predetermined voltage threshold is arranged, the outlet voltage value of relay is detected to judge to use
Family whether there is power generation behavior.
Step S32：When outlet voltage value is more than predetermined voltage threshold, judge that the user being connected with relay exists
Power generation behavior is forbidden sending switching signal to relay.In the embodiment of the present invention, when outlet voltage value is more than predeterminated voltage threshold
When value, illustrate that user may cannot send switching signal to relay in this case with electrical power generators, prevents and power grid
It is electrically connected together, might have voltage or phase is different, cause short circuit.
Step S33：When outlet voltage value is not more than default outlet voltage value, there is no the rows of power generation by judgement user
For.In the embodiment of the present invention, when outlet voltage value is not more than predetermined voltage threshold, subscribers' line connection is normal, continues to examine
Survey the impedance value of subscribers' line.
S3 can determine that user whether there is power generation behavior through the above steps, continue to execute step S4 to detect user's line
The impedance value on road.
Step S4：When judging user there are when power generation behavior, the impedance value for the subscribers' line being connected with relay is detected.
In the embodiment of the present invention, as shown in figure 3, resistance R46, R47, R48, R49 form current limliting bleeder circuit, signal source is provided to user
Load is detected, and is changed the end of incoming cables of relay and the ratio of outlet voltage and the resistance value of sampling resistor eventually by MCU
Calculate the load of user, the i.e. impedance value of subscribers' line.
Step S5：According to the magnitude relationship of impedance value and default impedance threshold, record breaker is from closed state to disconnection
Two interval times of the state to closed state.Impedance threshold is preset in the embodiment of the present invention, and there are two threshold value, i.e., first is default
Value, the second preset value, wherein first preset value is more than the second preset value.According to default impedance threshold and circuit-breaker status pair
It should be related to and the magnitude relationship of impedance value and default impedance threshold, judge breaker is opened or closed state.As shown in figure 5,
Step S5 is specifically included：
Step S51：Judge the magnitude relationship of impedance value and the first preset value, the second preset value.
Step S52：When impedance value is less than the second preset value, judgement breaker is in closed state, when impedance value is more than
When the first preset value, judgement breaker is off.In the embodiment of the present invention, impedance refers to the total load resistance of consumer electronics
Anti-, when impedance value is more than 200k Ω, judgement breaker is off；When impedance value is less than 20k Ω, breaker is judged
In closed state, user load impedance under normal circumstances is much smaller than 20k, if breaker disconnects, the subscribers' line of connection is just
It will disconnect, impedance will be very big.In the embodiment of the present invention, using 20k, 200k Ω as preset value, it is not limited thereto, at other
In embodiment, other numerical value can be arranged as required to.
Step S53：Record first interval time of the breaker from closed state to off-state, and from off-state to
Second interval time of closed state.In the embodiment of the present invention, the first interval time from closed state to off-state, from disconnected
Open state but is not limited sequentially to the second interval time of closed state with this.S5 is executed the step, open circuit can be obtained
Interval time between the state and state of device, next proceed to step S6.
Step S6：Judge whether two interval times are respectively less than preset time value.When being arranged default in the embodiment of the present invention
Between require be to ensure to have malfunction.
Step S7：When two interval times being respectively less than preset time value, switching signal is sent out to relay, drives relay
Device is closed.
When detect breaker from closed state to off-state again to closed state, and interval time is respectively less than 60s, then
Judgement is that user closes a floodgate in operating breaker, therefore, sends out combined floodgate order to relay, restores customer power supply.
Control intelligent electric energy meter closing switch method provided in an embodiment of the present invention is in combined floodgate permission state in intelligent electric energy meter
When (relay disconnection), by being detected to subscribers' line voltage, judgement user in the case of no power generation behavior, to
The circuit-breaker status at family is detected, and to judge operation of the user to breaker, is eliminated artificial manipulation intelligent electric meter and is closed a floodgate
When it cannot be determined whether there is the security risk of bringing of the conflict of power grid, while ensuring the personal safety of user, and meet
Simultaneously the user experience is improved for the installation environment of various intelligent electric meters.
