In this embodiment, the dual-power electricity charging method includes the following steps:
step S10: and monitoring the supply voltage of a supply line in the power grid.
It should be noted that, the execution body of the method of the embodiment may be a dual-power-supply electricity charging device for charging an electric energy meter, or other dual-power-supply electricity charging systems including the dual-power-supply electricity charging device capable of implementing the same or similar functions. The dual power charging method provided in this embodiment and the following embodiments will be specifically described with a dual power charging system (hereinafter referred to as a system).
It should be appreciated that the power supply line may be a line in the power grid that delivers and distributes electrical energy, such as: a mains supply line and a generator supply line. The mains supply line and the generator supply line can both transmit electric energy to the power utilization line so as to supply power for users.
It will be appreciated that the supply voltage may be a line voltage or a phase voltage at the supply point, as shown in fig. 3, for example, the system may collect a voltage value at the supply point when the a-channel of the mains supply line delivers power to the a-channel of the utility line.
In specific implementation, the utility power and the generator can both supply power, and the utility power is supplied to the power utilization line through the utility power supply line, and the generator is supplied to the power utilization line through the generator supply line, so that the user is supplied with power. When a user uses electricity, the system can monitor the voltage values of each line in the electricity consumption line, the commercial power supply line and the generator supply line in the power grid and check whether the voltage values of each line change.
Step S20: and when the fluctuation of the power supply voltage is monitored, acquiring the current power supply state of the power grid.
It should be noted that the power supply state may be a mains supply power supply and a generator power supply, when the system detects that the electric energy of the power line is the electric energy transmitted from the mains supply line, it is indicated that the electric network uses the mains supply to supply power at this time, and when the system detects that the electric energy of the power line is the electric energy transmitted from the generator power supply line, it is indicated that the electric network uses the generator to supply power at this time.
It should be understood that the system monitors the power supply voltage values of each channel of each power supply line in the power grid and the change situation of the power supply voltage values, when the power supply voltage value of a certain channel in the power supply line is monitored to have larger fluctuation, the power supply state in the power grid is about to be switched at the moment, and the current power supply state of the power grid needs to be acquired at the moment, so that the power supply state of the power grid about to be switched is judged.
In the specific implementation, when the utility power is used for supplying power in the power grid, the system detects that the voltage value of the utility power supply line tends to be stable at the moment, and monitors the voltage value of the power supply line continuously, when the utility power fails, a worker uses the generator for generating power as emergency power supply, and the system can monitor that the voltage values of the utility power supply line and the generator power supply line in the power grid have larger fluctuation at the moment, which indicates that the power supply state of the power grid is about to be switched at the moment, so that the current power supply state of the power grid needs to be acquired.
Step S30: and sending a charging mode switching signal to a target electric energy meter according to the current power supply state so as to enable the target electric energy meter to switch the charging mode and charge according to the switched charging mode.
It should be noted that, the target electric energy meter may be an electric energy meter corresponding to each user in the power grid, and if the power supply of the utility power is switched to the power supply of the generator in the power grid at this time, the target electric energy meter may be an electric energy meter corresponding to all users switched to the power supply of the generator in the current power grid.
It should be understood that the charging mode switching signal may be a signal sent by the system to the electric energy meter corresponding to the current power supply state of the power grid when the power supply state of the power grid is detected to change, and after receiving the signal, the target electric energy meter may switch the charging mode to the charging mode corresponding to the current power supply state, and perform charging of the electricity price through the charging mode corresponding to the current power supply state. The utility power supply and the generator power supply have different corresponding electricity prices, so that charging modes corresponding to different power supply states in the power grid are different, and when the power supply state of the power grid changes, the corresponding charging modes also need to be switched, so that the electric energy meter can charge the utility power supply state and the generator power supply state at the same time.
It can be understood that when the system can switch the charging mode in an automatic switching or manual switching manner, when the charging mode switching mode is set to be automatic switching, the system can automatically switch the charging mode according to the switching condition of mains supply and generator supply, when the charging mode switching mode is set to be manual switching, the charging mode of the electric energy meter can be remotely switched through the charging mode set by software, in addition, when the system detects that a new electric energy meter exists in the power grid, in order to ensure the unification of the charging mode switching modes of the electric energy meter in the power grid, a synchronous command can be sent to the target electric energy meter corresponding to the current power supply state and the new electric energy meter, so that the charging mode of the new electric energy meter is synchronized to the charging mode switching mode of the target electric energy meter.
In a specific implementation, as shown in fig. 3, the system may monitor the supply voltages of the utility power supply lines AN, BN and CN and the generator supply lines a ', B ' N ' or C ' N ' in the power grid, when the power grid is in the utility power supply state or the generator supply state, the supply voltage of the corresponding supply line is relatively stable, when the utility power fails, the generator emergency supply is used or the generator supply is converted into the utility power supply, the supply voltage of the supply line in the power grid will fluctuate greatly, which indicates that the power supply state of the power grid is about to be switched, at this time, the current supply state of the power grid needs to be acquired, for example, the voltage value of the channel AN for transmitting the electric energy to the power utilization line in the utility power supply line is detected to be about to be 0, and the supply voltage value of the channel a ' N ' for transmitting the electric energy to the power utilization line in the power generator supply line in the power supply line is increased, which indicates that the current supply state in the power grid is about to be converted from the utility power supply to the generator supply.
Further, as another implementation manner, in order to monitor the operation condition of the electric energy meter, the step S30 of this embodiment may further include: and monitoring the current running state of the target electric energy meter, and recording the current alarm state of the target electric energy meter when the running state is in a preset alarm state, wherein the preset alarm state is at least one of an open cover state, an open cover state and a phase failure state.
In a specific implementation, when the power supply state of the power grid is monitored to be mains supply, the mains power generation state indicator lamp is controlled to be normally on and displayed in red; when the power supply state of the power grid is monitored to supply power to the generator, the generator power generation state indicator lamp is controlled to be normally on and displayed in red; when the system is in an alarm state of opening the upper cover, opening the end cover or breaking the equal, the alarm lamp is controlled to flash for alarm; when the system works normally, the power supply lamp is normally on and is displayed green, and when the current alarm state of the electric energy meter is monitored to be in an alarm state of opening the upper cover, opening the end cover or being in an equal alarm state of failure, the current alarm state of the electric energy meter is recorded.
The embodiment discloses monitor the power supply voltage of power supply line in the electric wire netting, when monitoring that power supply voltage fluctuates, obtain the current power supply state of electric wire netting, send the charging mode switching signal to target electric energy meter according to current power supply state, so that target electric energy meter charges mode switching and charge according to the charging mode after switching, compared with the mode that the prior art uses the power consumption of individual statistics user electricity generation of generator, and charge according to the price of electricity corresponding to the generator electricity generation, because this embodiment can be through detecting the power supply voltage of power supply line in the electric wire netting, and send charging mode switching signal to the electric energy meter according to the current power supply state of electric wire netting when power supply voltage changes, thereby can make the electric energy meter switch charging mode according to the current power supply state of electric wire netting, the problem that the electric energy meter can not charge according to the charging mode that the generator supplies electricity corresponding when using the generator to supply electricity is solved, user experience has been improved.
Referring to fig. 4, fig. 4 is a flow chart of a second embodiment of the dual power charging method according to the present invention.
Based on the first embodiment, in order to detect whether the power supply state of the power grid is switched, in this embodiment, after step S20, the method further includes:
step S201: and when the current power supply state is mains supply, switching the power supply state into a generator power supply.
When the fluctuation of the power supply voltage of the power grid is monitored, the power supply state of the power grid is indicated to be switched, and the current power supply state of the power grid can be obtained at the moment, so that the power supply state of the power grid can be switched according to the current power supply state. For example, when the utility power fails, the utility power supply line is powered by the generator to generate power as emergency power supply, so as to ensure the power consumption of the user, at this time, the voltage value of the channel powered by the utility power supply line for the power consumption line tends to be 0, and when the utility power supply line is powered by the generator, the voltage value of the channel powered by the power consumption line for the power supply line of the generator increases, at this time, the power supply state of the power grid can be switched from the utility power supply to the power supply of the generator.
Step S202: first voltage data of a mains supply line and second voltage data of a generator supply line are collected.
It should be understood that the first voltage data may be larger voltage data in a mains supply line channel acquired after the power supply state of the power grid is switched from mains supply to generator supply, for example, voltage data of two channels of the mains supply lines a and B are acquired, and the voltage data of the two channels are compared to obtain the voltage data of the larger channel and then recorded as the first voltage data U1.
It can be understood that the second voltage data may be larger voltage data in the power supply line channel of the generator, which is collected after the power supply state of the power grid is switched from the mains supply to the power supply of the generator, for example, the voltage data of two channels of the power supply line a 'and B' of the generator are collected, and the voltage data of the two channels are compared to obtain the voltage data of the larger channel and then recorded as the second voltage data U2.
In a specific implementation, since the power supply state of the power grid is switched from mains supply to generator supply at this time, the voltage data of the mains supply line after switching will be smaller than the voltage data of the generator supply line, i.e. U1< U2.
Step S203: judging whether the power supply state is successfully switched to power supply of the generator or not according to the first voltage data, the second voltage data and a preset switching threshold value.
It should be noted that, the preset switching threshold may be a reference value for determining whether the switching is completed when the power supply state of the power grid is switched, and the preset switching threshold may be changed according to the actual situation, which is not limited in this embodiment, for example, the preset switching threshold is set to 50%.
It can be understood that the system can determine whether the power supply state of the power grid is switched according to the voltage data of the mains supply line, the voltage data of the generator supply line and the preset switching threshold value, which are collected after the power supply state is switched, for example: when (U2-U1)/U2 is more than 50%, the current power supply state of the power grid supplies power for the generator, and the power supply state switching of the power grid is completed.
In a specific implementation, when the mains supply fails or other special conditions occur, the generator is required to generate power, when the power supply state of the power grid is switched, the voltage values of the mains supply power supply line and the generator power supply line are greatly fluctuated, if the current power supply state is required to be switched from the mains supply power supply state to the generator power supply state at this time, in order to detect whether the power supply state is switched, voltage data of the switched mains supply power supply line and the generator power supply line can be collected, and whether the switching is completed can be judged according to a preset switching threshold value.
Further, as another implementation manner, in order to detect whether the power grid is switched from the generator power supply state to the mains power supply state, after the step S20, the method further includes: when the current power supply state is the power supply of the generator, the power supply state is switched to the mains supply; collecting third voltage data of a generator power supply line and fourth voltage data of a mains supply line; judging whether the power supply state is successfully switched to mains supply according to the third voltage data, the fourth voltage data and a preset switching threshold value.
According to the embodiment, the power supply state of the power grid to be switched is judged according to the obtained current power supply state of the power grid, the power supply state is switched, the voltage data of the mains supply power supply line and the generator power supply line are compared with the preset switching threshold value after the collected power supply state is switched, whether the power supply state of the power grid is switched is judged according to the comparison result, so that the electric energy meter can charge according to the charging mode corresponding to the power supply of the generator when the power supply state is switched to the power supply of the generator, and user experience is improved.
Referring to fig. 5, fig. 5 is a flow chart of a third embodiment of the dual power charging method according to the present invention.
Based on the above embodiments, in order to send a corresponding charging mode to the electric energy meter when the power supply state is switched, in this embodiment, before step S10, the method further includes:
step S01: and configuring a corresponding communication module for the target electric energy meter, wherein the communication module is an RS485 communication module, an RF communication module or a PLC communication module.
It should be noted that, the communication module may implement communication between the system and the electric energy meter, and the system may send, to the electric energy meter through the communication module corresponding to the electric energy meter, a charging mode corresponding to the current power supply state in the power grid. The corresponding communication module may be configured for the electric energy meter according to specific situations, for example: because the PLC communication module can adopt the electric wires of the power grid without additional wiring, but the transmission cost is higher and the transmission distance is limited when the power grid environment is poorer, the electric energy meter in the place where the power grid is dense can be configured as the PLC communication module.
Step S02: and when the configuration is completed, carrying out data interaction with the target electric energy meter based on the communication module, and judging whether the communication module and the target electric energy meter normally communicate or not according to a data interaction result.
