[0020] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.
[0021] like Figure 1 As shown, the module for simultaneous wireless upgrades of multiple photovoltaic protocol converters according to this invention includes a network receiving unit and a storage control unit. The network receiving unit is connected to a host computer via a network to remotely receive upgrade packages sent by the host computer. The network receiving unit is a smartphone or tablet with Bluetooth functionality and contains a 4G or 5G network module. In this embodiment, the network receiving unit is a smartphone with a photovoltaic management APP installed. This APP has functions such as device search, connection management, firmware download, upgrade package distribution, and upgrade status monitoring. Both the photovoltaic management APP and the smartphone are existing technologies and will not be described in detail here.
[0022] like Figure 1 As shown, the storage control unit is connected to the network receiving unit. The storage control unit has at least one serial port. The storage control unit is connected to the photovoltaic protocol converter in a one-to-one correspondence through the serial port. The storage control unit is used to receive the upgrade package from the host computer through the network receiving unit and send the upgrade package to each photovoltaic protocol converter through serial port IAP upgrade to upgrade all photovoltaic protocol converters. The storage control unit also feeds back the upgrade result of each photovoltaic protocol converter to the network receiving unit.
[0023] like Figure 1 As shown, in this embodiment, the storage control unit contains a chip U1 with model number MH2103ARPT6, and the Bluetooth module contains a chip U2 with model number N32G430C8L7. Both chips U1 and U2 have peripheral circuits that enable them to operate, which are existing technologies and will not be described in detail here.
[0024] Chip U1 is connected to chip U2. Chip U1 communicates with the network receiving unit via Bluetooth through chip U2. The specific connection structure between chip U1 and chip U2 can be found in their technical manuals and is existing technology, so it will not be described in detail here.
[0025] like Figure 1As shown, the lithium battery of the storage control unit is adapted and connected to chips U1 and U2 to provide power to them. Chip U1 is adapted and connected to the power module via a voltage detection module, which is used to detect the power level of the power module.
[0026] like Figure 2 As shown, the voltage detection module contains a PMOS transistor Q1. The positive terminal of the lithium battery is connected to the source of PMOS transistor Q1. The drain of PMOS transistor Q1 is connected to one end of resistor R4. The other end of resistor R4 is connected to one end of resistor R5, and the other end of resistor R5 is grounded. One end of resistor R4, connected to resistor R5, is connected to chip U1. Chip U1 is connected to the gate of PMOS transistor Q1 via an adapter connection, used to send a voltage test enable signal TEST_EN to the gate of PMOS transistor Q1. When PMOS transistor Q1 is turned on, one end of resistor R4, connected to resistor R5, generates a voltage sampling signal ADC, which is sent to chip U1. The gate of PMOS transistor Q1 is connected to one end of resistor R2. The other end of resistor R2 is connected to both resistor R1 and the collector of transistor Q2. The other end of resistor R1 is connected to the source of PMOS transistor Q1. The emitter of transistor Q2 is grounded, and the base of transistor Q2 is connected to one end of resistor R3, the other end of resistor R3 being grounded. The base of transistor Q2 is connected to chip U1 to receive the voltage test enable signal TEST_EN. By detecting the battery voltage, it ensures that the battery has sufficient charge to power the storage control unit when an upgrade is needed, avoiding the risk of power outages during upgrades. Furthermore, by using the switching action of PMOS transistor Q1 to detect the battery voltage only when an upgrade is required, the overall circuit power consumption is significantly reduced.
[0027] like Figure 3 As shown, when an upgrade is needed, the latest program is input into the upper-level machine (cloud server). The upper-level machine sends the program to the smartphone APP via 4G or 5G network. The staff connects the smartphone to the storage control unit via Bluetooth. The chip U1 has built-in Flash and SRAM to form a minimal operating system. The smartphone APP sends the upgrade program to the minimal operating system formed by the chip U1 via Bluetooth. The upgrade is sent to each photovoltaic protocol converter via serial port IAP to upgrade all photovoltaic protocol converters. The chip U1 also receives the upgrade result information from the photovoltaic protocol converter and transmits the upgrade result information to the APP via Bluetooth. The APP then feeds back to the host computer.
[0028] This invention relates to a module for simultaneous wireless upgrades of multiple photovoltaic protocol converters, enabling efficient and stable concurrent upgrades of multiple devices. This method not only improves upgrade efficiency and stability but also enhances user experience, demonstrating broad application prospects and promotional value.
