Existing lighting control systems usually use AC power as the sole power source and achieve basic control of lighting equipment through time switches, photosensors, or remote communication modules. Its core goal is to reduce energy consumption while meeting lighting needs.

However, in the process of using existing technologies, the inventors found that traditional lighting control systems have at least the following problems:

[0033] In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the present invention will be briefly introduced below in conjunction with the drawings and the description of the embodiments or the prior art. Obviously, the following description of the structure of the drawings is only some embodiments of the present invention. For those skilled in the art, other drawings can be obtained based on these drawings without creative work. It should be noted that the description of these embodiments is used to help understand the present invention, but does not constitute a limitation of the present invention.

[0034] Example 1:

[0035] This embodiment discloses a multi-energy storage control system, such as Figure 1As shown, the multi-energy storage control system includes a main control module, a first power conversion module, a new energy conversion module, an energy storage module, a boost drive module, a second power conversion module and a lighting module; the lighting module is provided with two power input terminals, the power input terminal of the first power conversion module and the power input terminal of the second power conversion module are both connected to the external power grid, the power input terminal of the new energy conversion module is connected to the new energy power supply terminal, the power output terminal of the first power conversion module and the power output terminal of the new energy conversion module are both connected to one power input terminal of the lighting module through the energy storage module and the boost drive module in sequence, and the power output terminal of the second power conversion module is connected to the other power input terminal of the lighting module; the controlled terminal of the first power conversion module, the controlled terminal of the energy storage module, the controlled terminal of the boost drive module and the controlled terminal of the second power conversion module are all connected to the main control module;

[0036] During a preset peak power consumption period, the main control module controls the boost drive module to operate so that the boost drive module performs a DC (Direct Current) / DC boost conversion on the power supply voltage of the energy storage module and then provides power support to the lighting module;

[0037] During a preset low-power consumption period, the main control module controls the operation of the second power conversion module so that the second power conversion module performs AC (Alternating Current) / DC conversion on the power supply voltage of the external power grid and then provides power support to the lighting module; at the same time, the main control module controls the operation of the first power conversion module so that the first power conversion module performs AC / DC conversion on the power supply voltage of the external power grid and then charges the energy storage module.

[0038] Specifically, in this embodiment, if the peak power consumption period is set to 18:00-24:00 every day (18:00 is the lighting time for the lamp, and 24:00 is the battery charging time for the lamp, and the charging time is controllable), during the peak power consumption period, the energy storage module is preferentially used to supply power to the lighting module. Staggering the peak electricity price can reduce the peak power load of the power grid, and the peak load is filled to save energy and protect the environment. If the low power consumption period is set to 00:00-7:00 every day, during the low power consumption period, the external power grid is preferentially used to supply power to the lighting module to achieve lighting, and the energy storage module is charged through the external power grid. The use of valley charging can reduce electricity costs, and the peak load is filled to save energy and protect the environment.

[0039] Furthermore, in this embodiment, during preset peak power consumption periods, the energy storage module is detected for abnormalities. If the energy storage module is in an abnormal state, the second power conversion module is controlled to operate, thereby performing AC / DC conversion on the power supply voltage from the external power grid and then providing power to the lighting module. Specifically, when the energy storage module's stored energy level falls below 10% or the battery pack used for energy storage experiences an abnormality, the lighting module automatically switches to AC power, i.e., power is supplied to the lighting module via the external power grid, while the energy storage module is automatically controlled to not charge, thereby ensuring stable lighting.

[0040] In this embodiment, Figure 2 As shown, the main control module uses the GD32F303RCT6 main controller U38 and its peripheral circuits. The GD32F303RCT6 main controller U38 is a high-performance single-chip microcomputer based on the ARM Cortex-M3 core. It has a built-in digital-to-analog converter that can convert digital signals into analog signals for driving various analog circuits or interfaces. Its operating efficiency is close to that of the STM32F3 series, but with lower power consumption, support for dynamic voltage regulation, and a rich set of peripheral interfaces, making it suitable for industrial control and communication scenarios.

[0041] Specifically, in this embodiment, the peripheral circuit of the main controller U38 includes an operation indication module, a communication module, a program burning module, a debugging module, a storage module and a clock module.

[0042] The operation indicator module includes a light-emitting diode (LED) D5 and a resistor (R41) connected to the main controller (U38). The LED (D5) illuminates when the main control module is operating, providing an operational indication. The communication module includes a communication port (U45) that can be connected to the communication terminal of the energy storage module. This port is isolated from the main controller (U38) via a π122U31 digital isolation chip (U44) to protect the main controller (U38). The program burning module utilizes the burning port (J7), and the debugging module utilizes the debugging serial port (J9), allowing users to program and debug the main controller (U38).

[0043] In this embodiment, the energy storage module includes a battery pack, a battery monitoring module, a battery management module and a battery voltage conversion module. The battery pack is connected to the battery management module via the battery monitoring module. The battery pack is also connected to the power input end of the battery voltage conversion module. The power output end of the battery voltage conversion module is the output end of the energy storage module.

[0044] like Figure 3As shown, the battery monitoring module adopts the SH3673520 battery monitor U4 and its peripheral circuits. The battery monitoring module is responsible for directly interacting with the analog signal of the battery pack, and is used to measure the voltage of a single cell in the battery pack (usually with an accuracy of ±1mV), measure the charge and discharge current through an external shunt resistor or Hall sensor, monitor the cell temperature of the battery pack through a thermistor, and achieve voltage balance between cells through resistor discharge.

[0045] like Figure 4 As shown, the battery management module uses an AT32L021 microcontroller U5 and its peripheral circuits. The peripheral circuits of the microcontroller U5 include a communication port J12, a debug port J10, and a burning port J11. This type of microcontroller U5 is an ultra-low-power ARM Cortex-M0+ core MCU launched by Arteli Technology. It has a main frequency of 48MHz, integrates 64KB Flash and 8KB SRAM, supports a wide voltage supply of 1.8~3.6V, and has a static power consumption of as low as 0.5μA (sleep mode). It includes hardware CRC acceleration, a 12-bit 1Msps ADC, multiple sets of USART / I2C / SPI interfaces, and a segment code LCD driver. It is suitable for smart homes, IoT terminals, wearable devices, and low-power scenarios powered by batteries, combining high performance and energy saving advantages. During implementation, the microcontroller U5 reads the battery status information from the battery monitoring module and sends this information to the main control module through the communication port J12, so that the main control module can remotely monitor and manage the energy storage module. In this embodiment, the battery management module is used to read the raw data collected by the battery monitoring module and can calculate the battery pack's SOC (State of Charge, also known as remaining capacity) and assess its SOH (State of Health), thereby providing fault protection for the battery pack in the event of overvoltage (OV), undervoltage (UV), overcurrent (OC), short circuit (SC), and abnormal temperature. In this embodiment, a dynamic voltage algorithm fuel gauge is used to calculate the battery pack's SOC. This gauge can calculate the SOC of a lithium battery based solely on the battery voltage. During use, the difference between the battery voltage and the battery's open-circuit voltage is used to estimate the SOC increment or decrement. The resulting dynamic voltage information can effectively simulate the behavior of the lithium batteries in the battery pack, thereby determining the SOC (%) and performing conversion between charge capacity (Wh) and discharge capacity (Wh).

[0046] like Figure 5 The figure shows the circuit schematic of the battery voltage conversion module, which uses the HXL1509-3.3 DC / DC buck converter, which helps save circuit board space and has an external shutdown function, and can enter standby mode through logic level control.

[0047] In this embodiment, the battery monitoring module can periodically scan multiple channels for synchronous sampling. It supports synchronous acquisition of multiple voltage / current signals (more than 4 battery cells) to avoid measurement errors caused by time difference (typical cycle 1s to 100ms), and performs temperature monitoring through an integrated temperature sensor to prevent thermal runaway. During implementation, the collected data of the battery monitoring module is sent to the battery management module, and the battery management module runs the SOC / SOH algorithm SOC estimation method to perform SOC estimation. If the SOC is unbalanced, the passive balancing function of the battery monitoring module can be activated, and the single cell voltage can be balanced through energy-consuming resistors. By setting the minimum SOC threshold to prevent overcharging / over-discharging, the battery can be adaptively charged and discharged, which is suitable for the development needs of smart cities.

[0048] After long-term technical demonstration and project operation tests, the design of energy storage lighting for road peak shaving and valley filling has multiple battery charging modes. When the battery voltage is low, the constant voltage charging mode is adopted. When the single battery (battery pack uses 8 single batteries connected in series) reaches 3V, the constant current charging mode is adopted. When the voltage reaches 90% of the fully charged voltage, the floating charging mode is adopted. This does not affect the battery charging and discharging performance and life, and ensures the lighting of important areas such as tunnels, urban traffic and bridges.

[0049] In this embodiment, the battery pack used for peak shaving and valley filling energy storage lighting uses a lithium iron phosphate battery cell series battery pack, which has an extremely high safety factor, supports high-power discharge and a wider operating temperature range, is highly safe, has a long service life, has low raw material costs (does not contain any heavy metals and rare metals), charges quickly, and has a wide operating temperature range (-15°C to +55°C).

[0050] like Figure 6 The figure shows a schematic circuit diagram of the new energy conversion module, which includes a new energy interface CN6 connected to the new energy power supply terminal. Its output terminal is connected to the energy storage module to provide new energy power support to the energy storage module. In this embodiment, the new energy source can be an external DC clean energy source such as solar energy, wind energy, etc., which is not limited here.

[0051] In this embodiment, Figure 7As shown, the boost driver module uses a Hi5000 constant current driver U48 to form a boost constant current driver module. It should be noted that the Hi5000 constant current driver U48 is a flicker-free LED constant current driver with a simple peripheral circuit and a wide dimming ratio. It can achieve a high-precision constant current effect, with an output current constant current accuracy of ≤±3%, a load regulation rate of <±0.5%, and a stable power supply output. It can meet the application requirements of a wide input and output voltage and dimming without flicker throughout the entire process. The boost constant current driver module supports buck, boost, and buck-boost topologies and is suitable for LED constant current lighting applications with an input voltage range of 6.5-75V. It has a deep dimming depth, good low-brightness load regulation and consistency, and also has undervoltage protection, temperature protection, reverse connection protection, and mains switching functions.

[0052] In this embodiment, Figure 8 As shown, the multi-energy storage control system also includes a lighting brightness adjustment module, the controlled end of the lighting brightness adjustment module is connected to the main control module, the power input end of the lighting brightness adjustment module is connected to the power output end of the boost driver module and / or the power output end of the second power conversion module, and the power output end of the lighting brightness adjustment module is connected to the lighting module. Specifically, in this embodiment, a light source interface CN4 for installing the lighting module is provided. The lighting brightness adjustment module includes a GP8101-F50-N-SW type voltage converter U41. Pin 3 of the voltage converter U41 is connected to the main control module through a resistor R76, pin 4 is connected to the output voltage of the boost driver module and / or the second power conversion module, pin 5 is grounded, pin 6 is connected to the power input pin of the light source interface CN4, pin 6 is also grounded through a capacitor C69 and a TVS diode D26, pin 7 is grounded through a resistor R80 and a capacitor C68, and pin 8 is connected to the junction of the resistor R80 and the capacitor C68. The GP8101-F50-N-SW voltage converter U41 has built-in filtering and driving circuits, and has a stable output, making it suitable for scenarios requiring analog voltage control, such as lighting dimming in this embodiment.

[0053] like Figure 8 As shown, the multi-energy storage control system also includes a backup power supply module, which includes a backup battery interface CN2 connected to the light source interface CN4 and a backup battery charging control module. The controlled end of the backup battery charging control module is connected to the main control module, and the main control module is used to charge the backup battery connected to the backup battery interface CN2 by controlling the backup battery charging control module.

[0054] In this embodiment, Figure 9As shown, the multi-energy storage control system also includes an energy storage discharge drive module, the controlled end of the energy storage discharge drive module is connected to the main control module, the power input end of the energy storage discharge drive module is connected to the power output end of the energy storage module, and the power output end of the energy storage discharge drive module is connected to the second power conversion module. In this embodiment, the energy storage discharge drive module includes a transistor Q16 and a P-type MOS transistor Q6. The base of the transistor Q16 is connected to the main control module through a resistor R58, the emitter of the transistor Q16 is grounded, the collector of the transistor Q16 is connected to the gate of the P-type MOS transistor Q6 through a resistor R57, the drain of the P-type MOS transistor Q6 is connected to the power output end of the energy storage module, the source of the P-type MOS transistor Q6 is connected to the gate of the P-type MOS transistor Q6 through a resistor R59 and a TVS diode D9 respectively, and the source of the P-type MOS transistor Q6 is the power output end of the energy storage discharge drive module and is connected to the second power conversion module. The main control module can realize power supply control of the energy storage module and the second power conversion module through the energy storage and discharge driving module, thereby realizing power supply control of the lighting module.

[0055] In this embodiment, Figure 10As shown, the multi-energy storage control system further includes a power grid data acquisition module and an isolation module. The signal acquisition end of the power grid data acquisition module is connected to the external power grid, and the signal output end of the power grid data acquisition module is connected to the main control module through the isolation module. In this embodiment, the power grid data acquisition module adopts the BL0942 type power metering chip U50 and its peripheral circuits. The power metering chip U50 has a built-in clock and is calibration-free. It is suitable for applications such as single-phase multi-function power meters, smart sockets and smart home appliances, and has a high cost-effectiveness. At the same time, the power metering chip U50 integrates two high-precision Sigma-Delta ADCs, analog circuit modules such as reference voltage and power management, and digital signal processing circuits for processing electrical parameters such as active power and effective values ​​of current and voltage. The BL0942 type power metering chip U50 is used for power grid data acquisition, which can realize high-precision real-time monitoring of parameters such as grid voltage, current, active power, reactive power, power factor and electric energy. It has the advantages of strong anti-interference ability, fast response speed and high integration, which helps to improve the accuracy and reliability of power grid energy efficiency management, and provide stable and accurate data support for scenarios such as smart meters, electricity consumption monitoring, and load analysis, thereby realizing comprehensive optimization of power usage status. The isolation module adopts the π122U31 type digital isolation chip U49, which can realize the electrical isolation between the main control module and the power grid data acquisition module and ensure the complete transmission of the signal, and can effectively prevent the high-voltage side from interfering with or damaging the main control module, thereby improving the system's anti-interference ability and safety; at the same time, the chip supports high-speed, low-latency data communication, ensuring the accuracy and real-time performance of the metering data during the isolated transmission process, thereby enhancing the overall stability and reliability of the system.

In this embodiment, the communication module adopts any one of a 4G (fourth generation mobile communication machine technology) module, a Zigbee (purple bee) module, and a GPRS (General Packet Radio Service) transceiver module, or any combination thereof. In this embodiment, the communication module adopts a UMA603 multi-mode wireless communication module, which can support a maximum downlink rate of 10Mbps and a maximum uplink rate of 5Mbps, and has a compact size, complete functions, and high cost performance.

[0057] In this embodiment, Figure 11 This is a circuit schematic diagram of a third power conversion module that can perform DC / DC step-down conversion on the power supply voltage of the energy storage module. It can convert the output voltage of the energy storage module into a +12V voltage for charging the backup battery and a 3.3V voltage for use by the main control module, thereby providing power support to the main control module and other modules.

[0058] This embodiment can realize the coordinated switching of energy storage power supply and mains power supply, improve energy utilization efficiency and operation economy, and support multi-energy power supply. Specifically, during the implementation of this embodiment, by setting a main control module, a boost drive module, an energy storage module, a dual-path power conversion module (composed of a first power conversion module and a second power conversion module) and a lighting module, dynamic switching control of the energy storage path and the mains power path is realized. During peak power consumption periods, the main control module controls the energy storage module to supply power to the lighting system via the boost drive module, effectively avoiding peak electricity prices. During low power consumption periods, the main control module controls the second power conversion module to supply power to the lighting via the mains, and controls the first power conversion module to charge the energy storage module, realizing peak-valley staggered charging. In addition, by setting a new energy conversion module, the present invention can simultaneously supply power to the energy storage module through new energy, and has a wider range of applications. Based on this, the energy management efficiency of this embodiment is high, which effectively solves the problems of uneven grid load, high electricity costs and lack of flexible management of energy storage paths in the prior art.
