Traditional lockers usually use AC electricity. In actual use, there are problems such as high construction and wiring costs and electricity costs, and there is also the problem of being unable to draw AC electricity in the deployment scenario. In order to solve the above problems, solar cell lockers came into being.

[0003] Currently, there are two types of solar cell lockers on the market: (1) using an industrial computer based on ARM architecture and Android operating system in conjunction with a touch screen to achieve human-computer interaction. The industrial computer communicates with the control board to control the storage compartment openings, and solar panels and batteries are added to the power supply. This type of solution has high power consumption, high cost, and requires a high-power battery pack; (2) based on a single-chip computer, using buttons in conjunction with an LCD display to achieve human-computer interaction. The single-chip computer IO directly drives the control circuit to control the storage compartment openings. This solution also has high power consumption.

[0053] Embodiment 2:

[0054] The present embodiment provides a solar cell storage cabinet, including a cabinet body, a main control module, a solar module, a battery module connected to the main control module, a human-computer interaction module and a sensor module, and the solar module is also connected to the battery module; wherein the specific implementation method of the main control module, the solar module, the human-computer interaction module and the sensor module is the same as that of the first embodiment, and will not be repeated here.

[0055] Different from the first embodiment, in order to realize the charge and discharge management of multiple battery packs, the battery module in this embodiment includes a battery charge and discharge circuit and at least one battery pack, and the battery charge and discharge circuit includes a charging branch and a discharging branch that match the number of battery packs, wherein the charging branch includes a first controllable switch, and the discharging branch includes a second controllable switch and a first diode; each battery pack is connected to the solar module (specifically, connected to the solar controller in the solar module) through the first controllable switch in the matching charging branch, and is connected to the anode of the first diode in the discharging branch through the second controllable switch in the matching discharging branch, and the cathode of the first diode in the discharging branch is connected to the power interface of the main control module; the main control module controls the connection of the first controllable switch in the charging branch and the second controllable switch in the discharging branch.

[0056] In this embodiment, the discharge branch also includes a first D trigger, the main control module is connected to the input end of the first D trigger in the discharge branch, and the output end of the first D trigger controls the second controllable switch in the discharge branch, so that the main control module can control the on and off of the second controllable switch in the discharge branch by changing the output state of the first D trigger.

[0057] like Figure 5 As shown, this embodiment takes a battery module with 4 battery packs as an example to introduce a multi-battery pack charge and discharge control circuit. After each battery pack is connected, the first D trigger in each discharge branch controls the battery pack to be in a discharge state by default. At this time, the main control module is powered on. The function of the first diode in each discharge branch is to prevent the uneven voltage backflow of each battery pack. After the main control module is powered on, it establishes communication with the battery pack BMS and can read the current power of each battery pack. After obtaining the power of each battery pack, the main control module can autonomously choose to keep only one battery pack to power the main control module (by changing the output state of the first D trigger in the discharge branch of the remaining 3 battery packs, so that the discharge branch is disconnected to turn off the power supply of the battery pack), thereby improving the battery life; at the same time, after obtaining the power of each battery pack, the main control module can autonomously control the solar module through IO to charge the battery pack with lower power; when the battery pack in the discharge state is low, the main control module can switch the high-power battery pack to power the main control module, and switch the low-power battery pack to the charging circuit, thereby improving the utilization rate of solar charging and reducing the manual maintenance cost.

[0058] In summary, this embodiment realizes a multi-battery pack charging and discharging design for a solar cell storage cabinet, and can automatically switch the charging and discharging state of the battery pack according to the power of each battery pack, thereby improving the utilization rate of solar power generation, enhancing battery life, and reducing manpower maintenance costs.

[0059] Embodiment three:

[0060] The present embodiment provides a solar cell storage cabinet, comprising a cabinet body, a main control module, a solar module, a battery module connected to the main control module, a human-computer interaction module and a sensor module, and the solar module is also connected to the battery module; wherein the specific implementation method of the main control module, the solar module, the battery module, the human-computer interaction module and the sensor module is the same as that of the second embodiment, and will not be repeated here.

[0061] Different from the second embodiment, the main control module of the solar cell storage cabinet in this embodiment is provided with a first external communication interface, and the first external communication interface is used to communicate with the main control modules of other solar cell storage cabinets to cope with the situation where multiple storage cabinets are used in parallel in actual applications. By using one of the solar cell storage cabinets as the main cabinet and the other solar cell storage cabinets as sub-cabinets, and setting a main and sub-cabinet wake-up mechanism, mutual communication between the main and sub-cabinets can be achieved.

[0062] The main cabinet wake-up circuit of this embodiment is as follows: Figure 6 As shown, J38 and J39 are the first external communication interfaces of the main control modules of the main cabinet and the sub-cabinet respectively.

In the default sleep state, the main control modules of the main cabinet and the sub-cabinet detect that the WAKEUP_MAIN signal is high. When the main cabinet needs to wake up the sub-cabinet, WAKEUP_FG is set high. At this time, pin 1 of J38 of the main cabinet outputs a 12V level, and pin 2 of J39 of the sub-cabinet is also 12V. At this time, the transistor Q182 of the sub-cabinet is turned on, and the main control module of the sub-cabinet detects that the WAKEUP_MAIN signal is pulled low, thereby waking up the sub-cabinet, and the sub-cabinet establishes communication with the main cabinet; similarly, when an abnormal event occurs in the sub-cabinet, the main cabinet is also awakened through the above operations, and the main cabinet and the sub-cabinet establish communication, and the abnormal event is reported through the main cabinet.

[0063] To sum up, this embodiment realizes the wake-up design of the solar cell storage cabinet when multiple storage cabinets are used in parallel. By reserving the first external communication interface for the main control module and designing the mutual wake-up circuit between the main and auxiliary cabinets, the sleep and wake-up logic of multiple cabinets can be realized, thereby further improving the battery life and reducing the power consumption of the whole machine.
