In the power generation and consumption process, if the specific standby power consumption or the working power consumption of the household appliance can be monitored, a reference can be provided for saving the power consumption of the household user. Meanwhile, with the enhancement of safety consciousness of people, higher requirements are placed on household safety electricity utilization. In traditional power consumption process, the user can not look over electric power data in real time, can not in time handle when leading to the potential safety hazards such as voltage anomaly or overcurrent, causes the power consumption incident, consequently, through the control to the domestic power consumption condition, also can provide the guarantee for the power consumption safety.
At present, most electric energy monitoring equipment used by families are electric meters, but the electric meters are arranged in outdoor electric meter boxes, and users cannot conveniently check the electric energy monitoring equipment. Although many of the electric meters are also smart meters, have a communication function, and can conveniently check electric energy data if the electric meters can be in communication connection with the smart meters, the electric meters are managed by an electric power company, and individual users cannot realize the communication connection with the electric power company. Therefore, in order to monitor the household power consumption and conveniently check the power data, a new power monitoring device needs to be installed in the household.

However, these devices that send out an alarm signal to the mobile phone or to the outside are often connected to the home network through WiFi or other methods, and when a dangerous situation occurs, the monitoring system needs to immediately cut off the power supply of the home, and in this situation, the home network cannot work due to power failure, and therefore, the device cannot send out an alarm signal to the outside. For example, patent document CN111965403A is a wireless mobile phone connected to a terminal computing device, and cannot send an alarm message in case of emergency power failure.
In consideration of the above problems, the power supply gateway still supplies electric energy to the acquisition terminal after the household emergency power failure, so that the acquisition terminal still can work, and the acquisition terminal has a mobile communication function, can still communicate with the outside even under the condition that the household network cannot be connected, and ensures that an alarm signal can still be sent out under the emergency condition.

The invention can also preset the charging standard of the electric charge, can automatically convert the electric charge of the current month according to the electricity consumption, and is convenient for users to intuitively know the electric charge condition of the current month.
The household power consumption monitoring system can be used for persistently storing electric energy data such as electric quantity, power, voltage, current and the like of household power consumption, so that a user can check historical power consumption conditions, the power consumption conditions and the power supply conditions are conveniently tracked and compared, power consumption awareness and safety power consumption awareness can be improved, power cost and expense can be reduced, a problem electric appliance can be found in advance, and a hidden danger disaster can be avoided.

Example 1:
referring to fig. 1, the visualized home power information monitoring system provided by the embodiment includes a power supply gateway 1, an acquisition terminal 2, and a display terminal 3.
The power supply gateway 1 is a household intelligent electric meter or an intelligent circuit breaker with a communication function, can acquire power consumption data or power supply data such as voltage, current, frequency, power factor, power consumption and the like, and can also control the on-off of power supply in a household in a manual or remote mode. The communication function of the power supply gateway 1 is RS485 protocol, and the communication protocol supports DL/T645-2007.
Although many electric meters installed by each household for charging electric quantity have a communication function, the household users cannot connect the electric meters, so that the power supply gateway 1, preferably a guide rail type device, can be newly installed at the total input end of indoor power supply, and can be conveniently installed in an indoor distribution box and is conveniently connected with a power supply cable.
The acquisition terminal 2 is in communication connection with the power supply gateway 1 through an RS485 protocol and used for acquiring electric energy data from the power supply gateway 1, and the connection between the acquisition terminal 2 and the power supply gateway 1 can be realized through an RVVP signal cable. The acquisition terminal 2 of the embodiment is realized by adopting an MCU singlechip. For a part of single-chip microcomputers which cannot directly process RS485 signals, RS485 to TTL modules can be adopted to convert the RS485 signals into TTL signals.
The acquisition terminal 2 of the embodiment also has a WiFi communication function, and can directly access a home WiFi network. Certainly, for some singlechips which do not support wireless transmission, the singlechips can be accessed to a home local area network or the internet through a wired network.
The display terminal 3 is in communication connection with the acquisition terminal 2, a user can check real-time electric energy data by operating the display terminal 3 to access the acquisition terminal 2 through a browser, and the electric energy data are displayed on a screen of the display terminal 3. The display terminal 3 may be an electronic device having display and network connection functions, such as a computer or a mobile phone.
The charging standard of the electricity charge is arranged in the acquisition terminal 2, and the electricity consumption can be automatically converted into the electricity charge, so that the electricity consumption cost of a user is more visual.
The user can set the acquisition terminal 2 through the display terminal 3, and the setting options comprise data acquisition frequency, data acquisition type, electric charge charging standard, network setting and the like.
According to the embodiment, the real-time electricity consumption information of a family can be checked through a computer or a mobile phone, the electricity consumption and the electricity charge information can be tracked, the electricity consumption power of the electric appliance can be obtained according to the power difference before and after the electric appliance is turned off and started, the electricity can be saved, the electricity charge cost is reduced, the electric appliance with problems can be found in advance, and the hidden danger disaster is avoided.
Example 2:
compared with the embodiment 1, the visualized household electric energy information monitoring system provided by the embodiment is improved as follows: the power supply gateway 1 also has the functions of alarming and automatically cutting off power supply.
The built-in buzzer of power supply gateway 1 of the embodiment can send out sound alarm signals, and when abnormal conditions such as overvoltage, undervoltage and overcurrent are detected in power supply, the buzzer can send out alarm sound to remind people in a room to notice. When dangerous voltage or dangerous current are detected, the power supply gateway 1 can send out more urgent alarm sound, and simultaneously cuts off power supply immediately, so that power utilization danger is avoided.
Similarly, the acquisition terminal 2 acquires the electric energy data of the power supply gateway 1 in real time, and when monitoring abnormal conditions such as overvoltage, undervoltage and overcurrent, alarm information can be sent to a preset mobile phone number or a mobile phone APP through a network to remind a user of paying attention.
Furthermore, the acquisition terminal 2 supports 2G, 3G, 4G and other mobile public network communication functions, the power supply gateway 1 can output a dc power supply, and the output dc power supply provides electric energy for the acquisition terminal 2.
In a home environment, network communication depends on network devices such as an exchanger and a modem, but after the power supply gateway 1 cuts off power supply, the network devices also cannot work due to power failure, and at this time, the acquisition terminal 2 cannot communicate with the outside through a home network.
When the embodiment works, after the power supply gateway 1 cuts off the power supply in an emergency, the power supply gateway can still work due to the fact that the power supply gateway is connected with an outdoor power supply line, and meanwhile, the acquisition terminal 2 connected with the power supply gateway can also work. At this time, when the acquisition terminal 2 detects that the home network cannot be connected, the acquisition terminal is automatically switched to the mobile network, so that the network communication is ensured to be normal, and an alarm signal under the emergency condition can be sent out.
