Description

Technical Field

[0001] A DC current sensor is an important device for measuring the current in a DC circuit, which can convert a DC current signal into a measurable electrical signal. The present invention relates to an amorphous alloy DC current sensor based on artificial intelligence, which is mainly used for precise current detection of battery circuits. Since the present invention uses an amorphous alloy iron core sheet material, and the sheet is wound into an iron core body in the form of an Archimedean spiral, it is small in size and has no openings in the structure. It can be widely used in load management and energy-saving control of fixed or mobile DC equipment, and has universal demonstration significance. Background Art

[0002] The amorphous alloy DC current sensor based on artificial intelligence is an innovative product that keeps up with the requirements of the times. It has the following six characteristics: 1. Conventional current sensors all use non-oriented cold-rolled silicon steel sheets as the core body, which have obvious crystallization characteristics, while the present invention uses a high-permeability amorphous alloy sheet with a disordered structure, which has extremely small no-load loss and significant energy-saving effect; 2. The amorphous alloy body sheet has the characteristics of a polishable mirror surface and scratch-resistant additive material, and is wound in the form of an Archimedean spiral. It has a small volume, small iron loss, and excellent magnetic properties. 3. The core bodies of conventional current sensors are all open feedback type, and the Hall element is installed in the air gap of the magnetic ring. The air gap is the area where the magnetic field intensity changes most significantly in the magnetic ring, but the existence of the air gap will inevitably reduce the accuracy of current detection. The amorphous alloy body described in the present invention has no openings and belongs to closed-loop feedback. Therefore, the detection accuracy is higher than that of the open core body. 4. The current sensor supports artificial intelligence technology from the bottom layer. Its core chip adopts the 32-bit LX7 dual-core processor chip of Xtensa architecture with a maximum main frequency of 240MHz. It integrates an ultra-low power coprocessor (ULP) and supports AI accelerated reasoning capabilities. In DeepSeek mode, the resident code in ESP32-S3 can be rewritten online through the standard API interface, and its AI model can be converted into the format of embedded devices.

[0003] 5. The current sensor has two Hall elements, thereby providing the hardware configuration required for the fault-tolerant algorithm; in addition, it also has a temperature sensor, which can transmit a temperature alarm signal to the core control chip when a large current causes a sharp fluctuation in the wire or ambient temperature.

[0004] Sixth, the current sensor is unique in three-dimensional design, and the convenience of installation and reliability of detection are fully considered in topological space. Six external input and output interfaces are added, and the system also supports standard CAN and extended CAN local area bus and 2.4G wireless WiFi local area network or Zigbee wireless local area network. Therefore, this highly operational amorphous alloy current sensor device can be widely used in various electronic circuits and is suitable for multi-dimensional application scenarios.

[0005] In summary, traditional current sensors obviously have many shortcomings and are far behind the requirements of keeping pace with the times. First, the volume cannot be reduced under the condition that the core body is made of cold-rolled silicon steel sheets, especially when the technical specifications of the current sensor vary depending on the application scenario, resulting in too large a change in volume; secondly, this type of current sensor faces considerable iron loss when detecting from milliamperes to thousands of amperes; and thirdly, the function is relatively simple, that is, it only has one function of converting the current signal into a measurable electrical signal; while the amorphous alloy body current sensor has extremely small iron loss and its volume can be reduced by an order of magnitude based on the original cold-rolled silicon steel sheet; more importantly, the current sensor is no longer a simple current sensor. With the support of artificial intelligence technology, it has further evolved into an AI embedded device and become an information node in artificial intelligence technology under a diversified use environment.

It can rewrite the resident code in ESP32-S3 online and convert its AI model into the format of embedded devices, which is more suitable for IoT applications; In order to further adapt to the development of the Internet of Things, the hexagonal junction box allows six external signal inputs or outputs, including a four-core standard CAN socket, a four-core extended CAN FD socket, and a socket with a 2.4G antenna, so it also supports 2.4G wireless WiFi LAN or Zigbee wireless LAN. In addition, the remaining connection interfaces of the hexagonal junction box also support the operation of equipotential bodies; The central part of the hexagonal junction box is provided with a central circular hole of the junction box, and six external wiring screw locking holes are provided around the central circular hole of the junction box.
