[0020] The present invention is further described in detail below in conjunction with examples, but the embodiments of the present invention are not limited thereto.

[0021] See also Figure 1 As shown, a one-household-one-code optoelectronic advantage integrated intelligent control system includes:

[0022] The intelligent light control module is used to control the solar photovoltaic power system by using the light intensity. According to the preset light intensity, when the light intensity is greater than the preset value, the solar photovoltaic power system is connected to the power storage device to charge the power storage device; when the light intensity is less than the preset value, the solar photovoltaic power system is disconnected from the power storage device. That is, the intelligent light control module is automatically adjusted according to the light intensity, and its set critical value can be adjusted according to the actual situation.

[0023] The intelligent time control module is used to charge the power storage device with the mains during the off-peak period, and to cut off the charging connection between the power storage device and the mains during the non-off-peak period. The electricity price is the lowest during the off-peak period, and the photovoltaic power generation system can only generate electricity during the day. When the light intensity reaches a certain level during the day, the solar photovoltaic power system is connected. This intelligent time control module is set according to the off-peak period of the mains, and the time period of the intelligent time control module is set and adjusted with reference to the off-peak period determined by each power department.

[0024] The intelligent capacity control module is used to automatically cut off the charging connection between the solar photovoltaic power supply system and the power storage device, or cut off the charging connection between the mains and the power storage device, or simultaneously cut off the connection between the solar photovoltaic power supply system and the mains and the power storage device when the power storage device is fully charged; and is used to automatically cut off the connection between the power storage device and the power consumption device when the power storage device is discharged to a preset value, so as to protect the power storage device.

[0025] The intelligent monitoring module is used to monitor the intelligent light control module, the intelligent time control module and the intelligent capacity control module. When an abnormal situation is detected, an alarm message is issued, and the connection between the abnormal module and other modules and the system and the device is cut off at the same time. It includes monitoring whether each photovoltaic panel is blocked. When the blocking range is detected to exceed the preset blocking warning value, the monitoring module sends an alarm message to the management terminal; and when the photovoltaic panel is accidentally damaged, the monitoring module sends an alarm message to the management terminal, including the location and number of the blocked photovoltaic panel or the damaged photovoltaic panel; it also includes lightning monitoring. When thunderstorms and other disaster weather are detected, the photovoltaic system and the mains power are automatically disconnected from the power storage device. And the power storage device is monitored. When the components of the power storage device are damaged, the operation of the capacity control module will be abnormal. Therefore, the monitoring of the power storage device can be achieved by monitoring the intelligent capacity control module. When the intelligent time control module controls the mains power to charge the power storage device, the intelligent time control module is monitored, and an alarm message is issued when an abnormal power outage is detected.

[0026] The password lock is used to manage one account password for one user. After entering the account password, you can enter the backend management to adjust the set values ​​of the intelligent light control module, intelligent time control module and intelligent capacity control module, and use digital means to record the information of each link of the system from manufacturing to use, which is convenient for problem tracing and product maintenance, and is also beneficial to system security.

[0027] In summary, the one-household-one-code optoelectronic advantage integrated intelligent control system of the present invention maximizes the advantages of municipal power and photovoltaic power generation, making their advantages complementary. It can not only reduce electricity costs, but also is beneficial to the stability of the power grid and ensures high-efficiency output of the energy system.
