Description

Technical Field

[0001] The present invention relates to the technical field of energy management, and in particular to a gateway-type energy management system. Background Art

[0002] The energy management system is a comprehensive system widely used in industries, construction, transportation and other fields. It is used to monitor, control and manage the generation, transmission, distribution and use of energy. Its main goal is to achieve efficient use of energy, reduce energy consumption, optimize energy costs and improve the sustainability of energy use.

[0003] With the popularization of new energy vehicles and the large-scale deployment of charging piles, as well as the increasing number of household appliances, the electricity usage situation has become more complicated and the demand for electricity has increased. It is inevitable that the power supply will be insufficient, which will not only lead to inefficient electricity use, but may also cause power outages due to excessive electricity use, or even fire accidents caused by overheating of the lines.

[0004] At present, the functions of energy management systems on the market are relatively simple. For example, the energy manager of a charging pile mainly measures the total incoming current value, communicates with the charging pile by wired or wireless means, and sends the available power of the charging pile according to the preset total incoming capacity and real-time power consumption, so as to achieve the function of managing power consumption.

[0005] This technology currently on the market may seem simple, but it actually has the following major shortcomings: 1. It has a single function and only reads the total incoming current. When the device consumes a lot of power, the manager cannot improve the charging efficiency; 2. When the home is equipped with energy storage devices, it cannot coordinate the power usage of the energy storage devices well; for relatively large charging stations, the energy manager is not sufficient to coordinate a large number of charging piles, which will lead to low operating efficiency of the entire station. Summary of the invention

[0006] The purpose of the present invention is to provide a gateway-type energy management system to solve the problems raised in the above background technology: 1. The function is single and only reads the total incoming current. When the equipment consumes a lot of power, the manager cannot improve the charging efficiency; 2. When the family is equipped with energy storage equipment, it is impossible to coordinate the power use of the energy storage equipment well; for relatively large charging stations, the energy manager is not enough to coordinate a large number of charging piles, which will lead to low operating efficiency of the entire station.

[0007] In order to solve the above technical problems, the present invention provides the following technical solutions: a gateway-type energy management system, comprising a microprocessor circuit, an LTE circuit, a WiFi circuit, a Zigbee circuit, an Ethernet circuit, an RS485 circuit, and a power management circuit, wherein the Ethernet circuit, the WiFi circuit, and the LTE circuit are used to communicate with the platform, and one of them is selected according to the on-site situation; The RS485 circuit is used to communicate with the external electrical parameter acquisition module and the circuit switch module; The WiFi circuit and Zigbee circuit are used to communicate with charging piles and smart appliances; The microprocessor circuit is used for communication data processing, power usage habit analysis, and coordination of the working status of each module.

[0008] Preferably, the microprocessor circuit adopts RV1126, and the LTE circuit adopts EG800.

[0009] Preferably, the WiFi circuit adopts CYW43438.

[0010] Preferably, the Zigbee circuit adopts ESP32-H2.

[0011] Preferably, the Ethernet circuit adopts YT8512H.

[0012] Preferably, the RS485 circuit adopts SP3485.

[0013] Preferably, the power management circuit adopts G2257.

[0014] Compared with the prior art, the beneficial effects achieved by the present invention are: First, the present invention has multiple communication modes and multi-protocol analysis, can connect to more devices, and has more flexible power control.

[0015] Second, the powerful processor performance of the present invention can better handle the communication data of multi-device networking, and can also analyze power usage habits through AI to coordinate power usage plans more intelligently.

[0016] Third, the present invention can ensure that electricity always operates within a relatively economical threshold through the coordination of electricity consumption of multiple devices, thereby reducing losses while ensuring safe electricity use, and saving energy and protecting the environment.

[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0019] See also Figure 1 and Figure 2 , a gateway type energy management system, including a microprocessor circuit, an LTE circuit, a WiFi circuit, a Zigbee circuit, an Ethernet circuit, an RS485 circuit, and a power management circuit, characterized in that: the Ethernet circuit, the WiFi circuit, and the LTE circuit are used to communicate with the platform, and one of them is selected according to the on-site situation; The RS485 circuit is used to communicate with the external electrical parameter acquisition module and the circuit switch module; The WiFi circuit and Zigbee circuit are used to communicate with charging piles and smart appliances; The microprocessor circuit is used for communication data processing, power usage habit analysis, and coordination of the working status of each module.

[0020] In this embodiment, a larger and more detailed energy management function can be implemented through the gateway-type energy management system. The gateway-type management system can optimize electricity consumption and improve electricity efficiency. Compared with the traditional energy manager with a single function, the gateway-type energy manager uses a variety of communication methods to network all electrical equipment, which can better coordinate electricity priorities, and conduct data analysis based on daily electricity usage habits, shut down low-priority electrical equipment, and ensure electricity consumption for high-priority electrical equipment, thereby greatly improving electricity efficiency, reducing losses, and saving energy and protecting the environment.

[0021] Specifically, the microprocessor circuit adopts RV1126, and the LTE circuit adopts EG800.

[0022] In this embodiment, RV1126 is a high-performance, low-power embedded processor based on the RISC-V architecture. It adopts advanced multi-core architecture and very long instruction word processing technology, can achieve efficient parallel computing and data processing, and provide excellent performance. Advanced process and power management technology can reduce power consumption while ensuring high performance and extend the battery life of the device. The LTE circuit EG800 module has built-in rich network protocols and integrates multiple industrial standard interfaces, which is more compatible with this case.

[0023] Specifically, the WiFi circuit uses CYW43438.

[0024] In this embodiment, the WiFi connectivity function is implemented by using a chip of the model CYW43438, which combines the functions of 2.4 GHz WLAN IEEE 802.11 b / g / n MAC / baseband / radio and Bluetooth 4.2.

[0025] Specifically, the Zigbee circuit uses ESP32-H2.

[0026] In this embodiment, ESP32-H2 not only supports Bluetooth 5 (LE), but also adds support for IEEE 802.15.4 technology, thereby supporting the Zigbee protocol. It has a complete security mechanism, including secure boot, flash encryption, and digital signature, providing reliable and secure connection performance for IoT devices.

[0027] Specifically, the Ethernet circuit adopts YT8512H.

[0028] In this embodiment, YT8512H is a low-power single-port 10 / 100 Mbps Ethernet PHY (physical layer) chip, which provides complete physical layer functions based on CAT5 twisted pair, suitable for application and industrial environment, with a wide temperature range (-50℃ to 125℃) and stable performance.

[0029] Specifically, the RS485 circuit adopts SP3485.

[0030] In this embodiment, in the RS485 communication circuit, SP3485 is used as an RS485 transceiver chip. In the application, the SP3485 chip realizes the connection between the microcontroller and other devices and the RS485 communication network. Since RS485 communication is half-duplex communication, data cannot be received at the same time when it is sent. Therefore, SP3485 is very suitable as an RS485 transceiver.

[0031] Specifically, the power management circuit adopts G2257.

[0032] In this embodiment, G2257 has control interfaces such as ENx and VFBx for realizing configuration and control of power management functions. Due to its wide input and output voltage range and flexible output configuration, it is suitable for a variety of power management applications and has high adaptability to this device.
