Step S100, when it is detected that the electrical connector is connected to a power supply device, determine the type of the connected power supply device;

Step S200: Control on/off between the power supply device and the load of the outdoor device according to the determined type of the power supply device.

In this embodiment, the outdoor equipment may be a doorbell, a surveillance camera, a speaker, or other outdoor equipment. The outdoor equipment can also be provided with an electrical connector, the electrical connector can be electrically connected with the power supply device, and the electrical connector can be a USB interface, specifically a Type-C interface, a mini USB interface, a Type-A interface, a Type-B interface or Other electrical connectors that can realize charging can be implemented, and the electrical connectors at least have a power input port and a power output port. The power input port of the electrical connector is used to connect the power supply equipment, and the power output port is used to connect to the outdoor equipment load, that is, the outdoor equipment load is connected to the power output of the power supply equipment through the power output port and the power input port of the electrical connector. . The electrical connector can be connected to different power supply devices, such as solar panels, power adapters, mobile power supplies, etc., that is, the power supply devices in this embodiment, such as the power adapter and the solar panel, can share a Type-C interface at the input end, so When one of the two exists, all power supply paths are the same, and both can supply power to the load in the outdoor equipment; when working, the power adapter and the mobile power supply can provide stable power to the outdoor equipment load. The solar panel can convert sunlight energy into DC power through the photovoltaic effect of solar cells and output it to the outdoor equipment through the power input port of the electrical connector to supply power to the outdoor equipment load in the outdoor equipment. It can be understood that the electric energy that the solar panel can generate is limited, and the electric energy generated by the solar panel will also fluctuate due to the weather and the intensity of sunlight. In addition, limited by the area of the solar panel, the power of the solar panel will not be too large, the solar panel cannot support the outdoor equipment load power supply for a long time, the outdoor equipment load will lose power, cannot work normally, and even cause data will be lost.

For this reason, this embodiment controls whether to directly supply power to the outdoor equipment load by controlling the on/off of the electrical connection between the power supply equipment and the outdoor equipment load. When the power input port and the power output port of the control electrical connector are electrically connected, The power supply equipment can be electrically connected to the outdoor equipment load through the power input port and power output port of the electrical connector, that is, an electrical connection is established between the power supply equipment and the outdoor equipment load, so that the power supply equipment can supply power to the outdoor equipment load. On the contrary, when the power input port and the power output port of the control electrical connector are electrically disconnected, a current loop cannot be formed between the power supply equipment and the outdoor equipment load, so that the power supply equipment cannot directly supply power to the outdoor equipment load, that is, the power supply equipment. The electrical connection to the outdoor equipment load is broken.

By detecting the type of power supply equipment connected to the power input port of the electrical connector, it is determined whether the type of the power supply equipment is a solar panel, a power adapter or a mobile power supply. Specifically, the current voltage value of the electrical connector connected to the external device can be detected, and the current power supply device type of the peripheral device can be identified according to the current voltage value and the preset mapping relationship between different voltage values and different interface types. It should be noted that when different power supply devices are connected to the electrical connector, the voltage values detected by the voltage detection circuit will be different. Therefore, in this embodiment, the corresponding relationship between each type of power supply device and the voltage value may be pre-defined, and the type of the power supply device to be connected may be determined based on the mapping relationship subsequently. In a specific embodiment, the electrical connector may be provided with a device type identification terminal, and the type of the connected power supply device may be determined according to the level of the device type identification terminal or the different voltage values. According to the detected power supply equipment type, it is determined whether the connected power supply equipment is a device that can directly supply power to the outdoor equipment load. The power supply equipment connected to the power input port of the connector directly supplies power to the load of the outdoor equipment. Otherwise, the electrical connection between the power input port and the power output port of the electrical connector is controlled to be disconnected. At this time, the power input port of the electrical connector is connected. The power supply equipment does not directly supply power to the outdoor equipment load.

The present invention determines the type of power supply equipment connected to the power input port of the electrical connector when it is detected that the power supply equipment is connected to the electrical connector, and controls the relationship between the power supply equipment and the outdoor equipment load according to the detected type of power supply equipment. The on/off time is used to disconnect the electrical connection between the power supply equipment and the outdoor equipment load when it is detected that the type of the connected power supply equipment is a device that cannot directly supply power to the outdoor equipment load. The invention solves the problem that when the power supply equipment is insufficient to support the power supply to the outdoor equipment load, the outdoor equipment load is directly powered off, and even data is lost in severe cases.

Referring to FIG. 2, in an embodiment, when it is detected that a power supply device is connected to the electrical connector, the step of determining the type of the connected power supply device specifically includes:

Step S110, when receiving the first sign signal, determine that the type of power supply equipment connected to the electrical connector is a solar panel;

In this embodiment, the solar panel is provided with a pull-down resistor, the pull-down resistor is connected to the device type identification lead port of the electrical connector, and the pull-down resistor is connected to the power supply control circuit of the outdoor equipment. When the solar panel is connected to the power input port of the electrical connector, a low-level signal is output, and when the first marking signal is received, it indicates that the type of power supply equipment connected to the power input port is a solar panel. On the contrary, when the mobile power supply or the power adapter is connected to the power input port of the electrical connector, since the pull-down resistor is not set, the low-level signal will not be output. When the first marking signal is used, it indicates that the type of power supply device connected to the power input port is a mobile power supply or a power adapter.

Referring to FIG. 3 , in an embodiment, the controlling of the power supply equipment on/off between the outdoor equipment loads according to the determined power supply equipment type includes:

Step S210, when it is determined that the type of power supply equipment connected to the electrical connector is a solar panel, control the electrical connection between the electrical connector and the load of the outdoor equipment to be disconnected;

Step S220, when it is determined that the type of power supply equipment connected to the electrical connector is a mobile power supply or a power adapter, control the electrical connection between the electrical connector and the outdoor equipment load to supply power to the outdoor equipment load .

In this embodiment, the power supply of the solar panel is unstable, so the solar panel is defined as a power supply device that cannot directly supply power to the outdoor equipment load, while the power output of the power adapter and the mobile power supply is relatively stable. And the power supply equipment that the mobile power supply directly supplies power to the outdoor equipment load. When it is determined that the type of power supply equipment to be connected is a mobile power supply or a power adapter, the control power input port and the power output port are electrically connected, and the mobile power supply or the power adapter can be electrically connected to the load of the outdoor equipment through the power input port and the power output port. , so that the power supply equipment can supply power to the outdoor equipment load. When it is determined that the type of power supply equipment to be connected is a solar panel, the electrical connection between the control power input port and the power output port is disconnected, and a current loop cannot be formed between the solar panel and the outdoor equipment load, so that the solar panel cannot directly supply Power supply to outdoor equipment loads.

4 , in an embodiment, the outdoor equipment further includes an energy storage system, and the energy storage system is respectively connected to the electrical connector and the outdoor equipment load; the outdoor equipment power supply control method further includes:

Step S300, when it is determined that a power supply device is connected to the electrical connector, control the energy storage system to store the electrical energy output by the power supply device.

In this embodiment, in the outdoor equipment, according to the different power supply equipment to be connected, an energy storage system can be selected, or an energy storage system can be selected not to be set up. into the energy storage system, or not into the energy storage system. For example, when the type of the connected power supply device is a power adapter, the energy storage system may not be set, and when the type of the connected power supply device is a mobile power supply or a solar panel, the energy storage system may be set. The energy storage system is directly connected to the power input port. When a power supply device is connected, the energy storage system can store the electrical energy provided by the power supply device. At this time, the power supply device can be one of solar panels, mobile power supplies and power adapters. one or more combinations.

Wherein, the energy storage system includes:

A charging chip and an energy storage battery, the input end of the charging chip is connected with the power input port of the electrical connector, and the output end of the charging chip is connected with the energy storage battery.

The charging chip is used to convert the electric energy output by the power supply equipment into the electric energy required by the outdoor equipment and then output it to the energy storage battery for storage. Specifically, the charging chip can perform DC-DC conversion, filtering, etc. on the electrical energy connected to the power input end of the electrical connector. The charging chip can adjust the power and charging voltage during charging, so that the charging of the energy storage battery can be in different stages. Optionally, the charging process of the charging chip includes but is not limited to a pre-charging stage, a constant-current charging stage, and a constant-voltage charging stage. The pre-charge phase is used to pre-charge (recovery) fully discharged battery cells. Precharging is usually done when the battery voltage is below around 3V. In the constant current charging stage, when the battery voltage rises to a predetermined charging threshold, such as 3V, the power is increased to perform constant current charging. In the constant current charging stage, the battery voltage gradually increases with the constant current charging process.

In a specific embodiment, the outdoor equipment is provided with an energy storage system, and when it is determined that the electrical connector is connected to a power supply device, the energy storage/working state of the energy storage system is controlled according to the type of the power supply device. Specifically, when it is determined that the type of power supply equipment connected to the electrical connector is a power adapter/mobile power supply, the power supply equipment is controlled to charge the energy storage system and simultaneously supply power to the outdoor equipment load. When it is determined that the type of power supply equipment connected to the electrical connector is When the type of power supply equipment is solar panel, control the solar panel to supply energy only to the energy storage system, and control the energy storage system to work at the same time to supply energy for the outdoor equipment load, that is, the electric energy when the outdoor equipment load is working is provided by the energy storage system .

5 , in one embodiment, the method for controlling power supply for outdoor equipment further includes:

Step S410, when it is determined that the type of power supply equipment connected to the electrical connector is a solar panel, detect the power stored in the energy storage system;

Step S420, when the power stored in the energy storage system is greater than or equal to a first power threshold, control the electrical connection between the electrical connector and the load of the outdoor equipment, so as to control the solar panel to supply the power to the outdoor equipment. Power supply to outdoor equipment loads.

In this embodiment, when the type of the connected power supply equipment is a solar panel, the solar panel preferentially provides power to the energy storage system, and the stored power in the energy storage system is relatively sufficient (greater than or equal to the first power threshold), or When the solar panel charges the energy storage system, so that the power stored in the energy storage system is relatively sufficient (greater than or equal to the first power threshold), the power input port and the power output port are controlled to be electrically connected, so that the solar energy The solar panel can provide electrical energy to the outdoor equipment load. At this time, the solar panel can continue to provide electrical energy to the energy storage system, and also provide electrical energy to the outdoor equipment load. When the energy storage system is fully charged, the energy storage system can stop receiving the output of the solar panel. The energy storage system closes its own charging function, and the solar panel only provides power to the outdoor equipment load. The first power threshold may be set to any value from 95% to 100%. It can be understood that when the power stored by the energy storage system is greater than or equal to the first power threshold, the power of the solar panel can also be detected, and whether the solar panel can provide stable power is determined according to the current power of the solar panel. To the outdoor equipment load, if it is, control the power connection between the power input port and the power output port; otherwise, it means that the power of the solar panel is less than the power required by the outdoor equipment load, that is, the energy storage system is charging or supplying power at the same time. The outdoor equipment load power supply can only maintain one of them. At this time, the energy storage system is given priority to supply power, that is, the control power input port is electrically disconnected from the power output port. In this embodiment, the power of the solar panel may be determined by detecting the current light intensity by an ambient light sensor, or by detecting the current output power of the solar panel by a power meter. For example, when the light is strong and the power is high, the solar panel can be controlled to supply power to the outdoor equipment load and the energy storage system at the same time. When the light is weak and the power is low, the solar panel can be controlled. The panels only supply power to the energy storage system.

Referring to FIG. 6, in one embodiment, the method for controlling power supply for outdoor equipment further includes:

Step S510, when it is determined that the type of power supply equipment connected to the electrical connector is a solar panel, detect the amount of electricity stored in the energy storage system;

Step S520 , when the detected electricity stored in the energy storage system is less than a minimum working electricity threshold, control the energy storage system to stop supplying power to the outdoor equipment load.

It can be understood that, when the type of power supply equipment connected to the electrical connector is a solar panel, in order to ensure stable power supply of the outdoor equipment load, this embodiment preferentially controls the energy storage system to supply power to the outdoor equipment load. However, in practical applications, the power of the energy storage system may be too low to support power supply to outdoor equipment loads. In order to ensure that the load of the outdoor equipment will not be powered down because the power of the energy storage system is too low, or even lose data in severe cases, in this embodiment, the power stored in the energy storage system can be determined first. When the load cannot work normally, when the power of the energy storage system is lower than the minimum working power threshold, that is, the power of the energy storage system is insufficient, the power supply of the energy storage system is given priority, and the power supply function of the energy storage system to the outdoor equipment load is turned off to prevent the outdoor equipment from supplying power. The load further consumes the power of the energy storage system. Specifically, when it is detected that the electrical connector is connected to the power supply device, for example, the power supply device is inserted into the Type-C interface of the outdoor device, the power of the energy storage system is detected, and the power of the energy storage system is compared with the minimum working power threshold. right. When the power stored by the energy system is less than the minimum working power threshold, the energy storage system only receives the power of the solar panel, and does not transmit power to the outdoor equipment load. load power supply. Since the solar panel only supplies power to the energy storage system, it will not be cut off frequently. The solar panel charges the energy storage system instead of supplying power to the outdoor equipment load, which can improve the battery life of the energy storage system. Wherein, the minimum working power threshold is the minimum power required for the outdoor equipment load to work normally, and when the outdoor equipment load is lower than the minimum working power threshold, it cannot work normally.

Referring to FIG. 6, in one embodiment, the method for controlling power supply for outdoor equipment further includes:

Step S530: When the detected electricity stored in the energy storage system is greater than or equal to a second electricity threshold, control the energy storage system to supply power to the outdoor equipment load.

In this embodiment, the power of the solar panel cannot maintain the simultaneous power supply of the outdoor equipment load and the energy storage system. When it is determined that the power of the energy storage system is greater than or equal to the second power threshold, the energy storage system can turn off or maintain its own charging function, and at the same time control the energy storage system to supply power to the outdoor equipment load, and continuously judge the power of the energy storage system :

When the power of the energy storage system is less than the second preset power threshold, the energy storage system is controlled to start its own charging function, and at the same time, the energy storage system is controlled to stop supplying power to the outdoor equipment load, and the energy storage system starts charging at this time;

When the power of the energy storage system is greater than or equal to the second preset power threshold, the energy storage system is controlled to supply power to the outdoor equipment load until the power of the energy storage system is less than the second preset power threshold. Among them, the second preset power threshold value indicates the power value of the energy storage system that is about to reach the minimum working power threshold, so as to prevent the energy storage system from continuing to charge the outdoor equipment load when the energy storage system reaches the minimum working power threshold, resulting in the energy storage system due to low power As a result, the load of the outdoor equipment is directly powered off. And when the power of the energy storage system is less than the second preset power threshold, the microcontroller in the outdoor equipment load can be triggered to store data, so as to prevent system data loss due to instantaneous power failure. Wherein, the second power threshold is greater than the second preset power threshold.

7 , in one embodiment, the method for controlling power supply for outdoor equipment further includes:

Step S610, when it is determined that the type of power supply equipment connected to the electrical connector is a solar panel, detect the power of the solar panel;

Step S620, when it is determined that the power of the solar cell panel is greater than or equal to a first power threshold, control the electrical connector to be electrically connected to the outdoor equipment load.

In this embodiment, the output voltage and current of the solar energy obtained by the solar panel after photoelectric conversion are non-linear. With the change of sunshine conditions, the solar panel can output high-power electric energy after photoelectric conversion, that is, in the sunshine When sufficient, the solar panel can absorb more solar energy and convert it into charging electric energy to the greatest extent, so that the power of the solar panel can maintain the load of outdoor equipment and the energy storage system at the same time. When the power of the solar panel is sufficient (greater than or equal to the first power threshold) to supply power to the energy storage system and the outdoor equipment load at the same time, the power input port and the power output port may be controlled to be electrically connected to Make the solar power panel supply power to the outdoor equipment load, and once the power of the solar panel is less than the first power threshold, the electrical connection between the power input port and the power output port is controlled to be disconnected, and the power supply equipment connected to the power input port is only Charge energy storage systems without directly powering outdoor equipment loads.

Among them, the power can be judged by the output power. When the power of the connected solar panel is less than the power required by the outdoor equipment load, that is, the solar panel is not enough to supply power for the outdoor equipment load, and the energy storage system needs to further Supplementary power supply for outdoor equipment loads. In order to prevent the load of the outdoor equipment from continuing to lose the power of the energy storage system when the power of the energy storage system is at a low level, thus causing the load of the outdoor equipment to fail to work normally, in this embodiment, the power of the solar panel may be lower than that required by the load of the outdoor equipment. When the power of the outdoor equipment is equal to the power of the energy storage system, the outdoor equipment load and the power supply path of the energy storage system are dynamically adjusted based on the power of the energy storage system, so as to balance the power of the outdoor equipment load and the energy storage system. If the power of the solar panel is greater than or equal to the power required by the outdoor equipment load, it means that the current solar panel is sufficient to supply power to the outdoor equipment load. Power on. In a specific embodiment, when the power of the solar panel is exactly equal to the current required by the load of the outdoor equipment, that is, the solar panel cannot supply power to the load of the outdoor equipment and the energy storage system at the same time, the current energy of the energy storage system and the current outdoor equipment can be further combined. The load power is allocated to the power supply path to balance the power of the energy storage system and the power demand of the outdoor equipment load, so that both the outdoor equipment load and the energy storage system can work normally.

The present invention also provides an outdoor equipment power supply control system, comprising a processor, a memory, and an outdoor equipment power supply control program stored on the memory and running on the processor, wherein the outdoor equipment power supply control program is The steps of implementing the above-mentioned method for controlling the power supply of outdoor equipment when executed by the processor are described.

On the contrary, when the system power supply detection control circuit 10 controls the power supply input port VBUS_5V and the power supply access port VBUS_5V_P to be electrically disconnected, a current loop cannot be formed between the power supply equipment and the outdoor equipment load, so that the power supply equipment cannot directly supply power to the outdoor equipment load. .
