These modules are connected via wires or signal transmission lines to form a complete system architecture.

[0028] The main control unit 1 is the core control component of the entire system. Its input terminal is connected to an external signal source via a signal line, and its output terminal is connected to the first switching module 2 via a control signal line. The main control unit 1 contains a microprocessor and memory, used to receive operating mode data from the external signal source and generate control signals according to preset logic. The first switching module 2 uses a dual-channel switch as its core component. Its fixed end is bolted to the output terminal of the load interface module 5. The first channel end is connected to the first detection unit 3 by soldering, and the second channel end is connected to the second detection unit 4 by soldering. The dual-channel switch has an internal electromagnetic drive mechanism. When the main control unit 1 outputs a control signal, the electromagnetic drive mechanism moves the switching contacts, thereby selectively connecting the load interface module 5 to either the first detection unit 3 or the second detection unit 4.

[0029] The first detection unit 3 includes a first voltage detection circuit and a first current detection circuit, and the second detection unit 4 includes a second voltage detection circuit and a second current detection circuit. The input terminals of both the first voltage detection circuit and the first current detection circuit are connected to the first channel terminal of the first switching module 2 via wires, and the input terminals of both the second voltage detection circuit and the second current detection circuit are connected to the second channel terminal of the first switching module 2 via wires. The first voltage detection circuit acquires the output voltage of the load interface module 5 through a voltage divider resistor network, and the first current detection circuit acquires the output current of the load interface module 5 through a current transformer. The second voltage detection circuit and the second current detection circuit employ a similar principle, but their circuit parameters are optimized to suit different types of load characteristics. The output terminals of the first detection unit 3 and the second detection unit 4 are connected to the input terminals of the main control unit 1 via signal lines, respectively, to transmit the acquired data to the main control unit 1 for processing.

[0030] The environmental sensing module 6 includes a temperature sensor and a light intensity sensor. The temperature sensor uses a thermistor as its core component, reflecting changes in ambient temperature by measuring changes in resistance. The light intensity sensor uses a photodiode as its core component, measuring light intensity through photoelectric conversion. The temperature and light intensity sensors are connected to the control terminal of the second switching module via an I2C bus. The input terminals of the second switching module are connected to the output terminals of the first detection unit 3 and the second detection unit 4 via signal lines, respectively. The output terminals are connected to the display panel 7 via ribbon cables. The display panel 7 uses an LCD screen as its display medium, which can intuitively present the system's operating status and detection data. The environmental sensing module 6 collects environmental data and controls the second switching module to selectively transmit data from either the first detection unit 3 or the second detection unit 4 to the display panel 7.

[0031] The short-range communication unit 8 communicates with external devices via wireless radio frequency technology. Its antenna is connected to the output of the third switching module via an SMA interface to ensure reliable signal transmission. The control terminal of the third switching module is connected to the environmental sensing module 6 via a signal line, and its input terminals are connected to the output terminals of the first detection unit 3 and the second detection unit 4 via signal lines. Its output terminal is connected to the short-range communication unit 8 via a signal line. Based on the data collected by the environmental sensing module 6, the third switching module selectively transmits data from the first detection unit 3 or the second detection unit 4 to the short-range communication unit 8, enabling real-time communication with external devices.

[0032] Alarm unit 9 is connected to main control unit 1 via a relay.

Remote communication unit 10 uses a 4G module to communicate with the cloud server. Its SIM card slot is fixed to the module housing with a clip for easy replacement and maintenance. The input terminal of remote communication unit 10 is connected to the output terminal of main control unit 1 via a signal line, used to upload the system's operating status and detection data to the cloud server.

[0033] The system operates as follows: The main control unit 1 receives operating mode data from an external signal source via a signal line and generates a control signal based on preset logic. This control signal is then transmitted to the first switching module 2 via the control signal line. Upon receiving the control signal, the first switching module 2 uses an electromagnetic drive mechanism to move the switching contacts, selectively connecting the load interface module 5 to either the first detection unit 3 or the second detection unit 4. The first detection unit 3 and the second detection unit 4 respectively collect the operating parameters of the load interface module 5 and transmit the collected data to the main control unit 1 for processing via the signal line. The main control unit 1 determines whether the operating mode needs adjustment based on the processing results and dynamically adjusts the first switching module 2 via the control signal line.

[0034] The environmental sensing module 6 collects environmental data through temperature and light intensity sensors and transmits the collected data to the second switching module via an I2C bus. The second switching module selectively transmits data from either the first detection unit 3 or the second detection unit 4 to the display panel 7 based on the environmental data. The display panel 7 displays the system's operating status and detection data on an LCD screen. Simultaneously, the environmental sensing module 6 transmits the collected data to the third switching module via a signal line. The third switching module selectively transmits data from either the first detection unit 3 or the second detection unit 4 to the short-range communication unit 8 based on the environmental data, enabling real-time communication with external devices.

[0035] When the main control unit 1 detects an abnormal operating state, it outputs a trigger signal and transmits it to the alarm unit 9 via a signal line. The alarm unit 9 then activates the alarm device via a relay. The remote communication unit 10 receives the operating status and detection data transmitted by the main control unit 1 via a signal line and uploads the data to the cloud server via a 4G module, enabling remote monitoring and management.

[0036] The above describes in detail the connection relationships, positional relationships, and mutual cooperation relationships between the various modules of this system, as well as the system's operation process. Through the above implementation method, this system can dynamically switch detection units under different operating modes to meet the efficient control requirements of various types of loads, while improving the system's intelligence level and security.

[0037] To enable those skilled in the art to fully understand and implement this utility model, the specific implementation principle of this utility model is further supplemented below with a specific application scenario.

[0038] In new energy power generation scenarios, inverter power supply control systems are widely used to convert direct current (DC) generated by photovoltaic panels into alternating current (AC) and supply power to loads. The following describes the operation steps and implementation principles of a high-efficiency inverter power supply control system based on multi-mode switching in this scenario.

[0039] First, upon system startup, the main control unit 1 receives operating mode data from an external signal source via a signal line. This data may originate from the central controller of the photovoltaic power generation system, indicating the currently required operating mode, such as constant voltage mode or constant current mode. The main control unit 1 generates a control signal based on preset logic and transmits it to the first switching module 2 via the control signal line. Upon receiving the control signal, the first switching module 2 activates its internal electromagnetic drive mechanism, moving the switching contacts to selectively connect the load interface module 5 to either the first detection unit 3 or the second detection unit 4. This process ensures that the system can dynamically switch detection units according to different load characteristics, thereby adapting to different operating mode requirements.

[0040] Next, the first detection unit 3 and the second detection unit 4 collect the operating parameters of the load interface module 5. The first voltage detection circuit and the first current detection circuit achieve accurate acquisition of the output voltage and current of the load interface module 5 through a voltage divider resistor network and a current transformer, while the second voltage detection circuit and the second current detection circuit are optimized for different types of load characteristics. The collected data is transmitted to the main control unit 1 for processing via signal lines. The microprocessor inside the main control unit 1 analyzes the received data in real time to determine whether the operating mode needs to be adjusted. If adjustment is required, the main control unit 1 will generate a control signal again and dynamically adjust the first switching module 2 through the control signal line to ensure that the load operating state is always within the optimal range.

[0041] Meanwhile, the environmental sensing module 6 collects environmental data through temperature and light intensity sensors. The temperature sensor uses a thermistor as its core component, reflecting changes in ambient temperature by measuring changes in resistance. The light intensity sensor uses a photodiode as its core component, measuring light intensity through photoelectric conversion. The collected environmental data is transmitted to the second switching module via an I2C bus. The second switching module selectively transmits data from either the first detection unit 3 or the second detection unit 4 to the display panel 7 based on the environmental data. The display panel 7 visually presents the system's operating status and detection data on an LCD screen, facilitating real-time monitoring by operators. For example, in low light intensity conditions, the system may automatically switch to constant current mode to maintain stable load operation, while the display panel 7 displays the current operating mode and environmental parameters.

[0042] Furthermore, the short-range communication unit 8 communicates with external devices via radio frequency technology. The third switching module selectively transmits data from either the first detection unit 3 or the second detection unit 4 to the short-range communication unit 8 based on data collected by the environmental sensing module 6, enabling real-time communication with external devices. For example, when the ambient temperature is too high, the system can send an alarm message to a nearby monitoring terminal via the short-range communication unit 8 to remind operators to take cooling measures. The remote communication unit 10 uploads the system's operating status and detection data to a cloud server via a 4G module, enabling remote monitoring and management. This two-layer communication mechanism not only improves the system's scalability but also enhances its security.

[0043] When the main control unit 1 detects an abnormal operating state, such as when the load current exceeds the safe range, it outputs a trigger signal that is transmitted to the alarm unit 9 via a signal line. The alarm unit 9 then activates the alarm device via a relay, emitting an audible and visual alarm signal to alert the operator to take timely action. Simultaneously, the remote communication unit 10 uploads the abnormal data to the cloud server for subsequent analysis and troubleshooting.

[0044] Through the above steps, this system can achieve efficient and intelligent inverter power supply control in complex new energy power generation scenarios. The system dynamically switches detection units to adapt to different load characteristics through the coordinated operation of the main control unit 1, the first switching module 2, the first detection unit 3, and the second detection unit 4. The introduction of the environmental sensing module 6 and the display panel 7 enhances the system's intelligence level. The setting of the alarm unit 9 and the remote communication unit 10 enhances the system's security and scalability. The above description is only a preferred embodiment of this utility model and is not intended to limit this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
