Description

Technical Field

[0001] The present invention relates to a multi-modal DC power high-speed switch supporting artificial intelligence technology. Compared with traditional electromagnetic switches, this high-speed power switch supports dual CAN bus communications, and relay elements are not used for power devices. Therefore, the switching action response time is at least one order of magnitude faster than that of traditional high-power relay electromagnetic switches, and it completely changes the situation of information islands in DC power switches, becoming a key special component used in electric vehicles and artificial intelligence robots. It can be widely applied to various large mobile electronic devices, and can also be used as the main switch of the lithium battery power supply of electric vehicles or as a high-speed zero-leakage protector with high power. Background Art

[0002] Basically, traditional DC circuit breakers all use contact relay elements. Since the magnetic force generated by the current needs to overcome the reaction spring before the armature can move, three prominent problems are brought about: First, the switching action time of traditional DC circuit breakers is mostly limited to the millisecond level, and the switching action cannot be fast; second, there is arcing and electro-corrosion phenomenon on the contacts of the relay, and over time, adhesion will occur between the moving and fixed contacts of the relay; third, the explosion and combustion action time of the DC power lithium battery pack also occurs within a millisecond instant. Therefore, it is very necessary to prevent problems before they occur and quickly cut off the DC power in high-power mobile electronic devices using lithium battery packs.

[0003] The main design intention of the present invention is mainly to solve the problem of rapid on-off in the case of large DC current. Accordingly, the present invention proposes a design scheme that is the most economical and optimal for the whole system according to the theory of systems engineering, and incidentally solves the heat dissipation and leakage problems of contactless MOS transistors. The wonderful thing is that the main body skeleton combines the explosion-proof junction box and the power switch into one, with four groups of highly sensitive digital current sensors and two-way digital temperature sensors inside. The execution component abandons the traditional electromagnetic circuit and adopts contactless high-speed MOS devices, and the switching action time is shortened to the microsecond level. Therefore, the safety of devices powered by lithium batteries can be greatly improved; on the other hand, the present invention not only supports the discharge operation of the lithium battery pack but also can charge the lithium battery pack, thus greatly expanding the practicality of this high-speed power switch.

[0004] It can be said that the multi-modal DC power high-speed switch supporting artificial intelligence technology proposed by the present invention is no longer a single switch component, but also hides unexpected black technologies. Because its fast response ability shows that it can cut off the power supply of the lithium battery pack in an extremely short time to protect the safety of personnel and equipment, and there is no electromagnetic arcing phenomenon during the instant of the switching action, so the electro-corrosion phenomenon between contacts will not occur. This not only extends the service life of the high-speed switch, but also has a faster action and higher reliability than traditional protection devices with electromagnetic tripping.

[0005] More importantly, this high-speed power switch can also replace the conventional zero-point leakage protector. Since there is an input digital current transformer and three output digital current transformers inside the circuit, the switch can detect whether the input current and the output current in the circuit are balanced with high sensitivity, so as to closely monitor the balance state of the total current and accurately judge whether there is a leakage phenomenon in the system. If there is no leakage, the vector sum of the total current is zero; if there is a leakage or a tiny leakage current appears, the balance of the total current vector sum will be broken, and the high-speed power switch of the lithium battery will quickly cut off the power supply to prevent the risk of electric shock or fire caused by the explosion of the lithium battery with an ultra-fast speed to prevent problems before they occur, thus achieving the purpose of zero-point leakage protection. Obviously, the multi-modal DC power high-speed switch supporting artificial intelligence technology can be widely used in large mobile electronic devices and can effectively reduce the incidence of electrical accidents.

[0006] Especially valuable is that in the current era when artificial intelligence technology is in the ascendant, this DC power high-speed switch adopts a dual CAN bus communication method. Its CAN interface power supply is powered by a third party or another battery pack, so there is no need to worry about the power supply problem after the DC power supply is cut off; the dual CAN buses include: one is a CAN bus for standard 8-bit data packets, which communicates with the internal microprocessor; the other is an extended 64-bit data packet CAN FD bus, which can communicate with the upper computer through networking, thus ensuring that the power switch also becomes a node of local area network communication. Through API (Application Programming Interface) interaction, it can also be upgraded to an intelligent general robot with deep learning ability and scalability under multi-modal algorithms. Even the health status of the lithium battery pack can be sent to the upper computer through the CAN FD bus, and an analysis report of the remaining battery capacity (SOC) and power factor analysis report can be provided to the customer in a timely manner. Each power on and off has a real-time record and cause analysis. Especially when there is a system leakage, the leakage information or power-off reason information can be uploaded in time through the CAN bus, thus opening up a particularly valuable innovation field in the new energy market and the digital civilization era.

[0007] In the multi-modal DC power high-speed switch described above, all the components selected are domesticated. Even the core microcontroller chip is the domestic ESP32-S3, which is a chip with a 32-bit LX7 dual-core processor using the Xtensa architecture, with a maximum main frequency of 240MHz, integrated with an ultra-low-power co-processor (ULP), supporting AI acceleration and inference capabilities. In the DeepSeek mode, the resident code in the ESP32-S3 can be rewritten online through the standard CAN interface, and its AI model can be converted into the format of an embedded device, thus upgrading its DC power high-speed switch fantastically into a node post on the information superhighway.

For this purpose, an interface API circuit for interaction between software and hardware and a logic conversion interface circuit for dual CAN buses are also designed; The power driver chip, power power device and high-frequency transformer cooperate to convert the input DC voltage into the working voltage required by the PCB circuit board online; On the described explosion-proof junction box, there is a wiring plug on each side. After the external connection passes through the wiring plug, the connection is locked by screwing the screw through the wiring screw fixing hole. Among the 6 wiring plugs, two wiring plugs are defined as DC inputs, two wiring plugs are defined as DC outputs, and two wiring plugs are respectively defined as the connection ports for the standard CAN bus and the extended CAN FD bus. The wiring plugs connected to the standard CAN bus and the extended CAN FD bus are engraved with internal threads of the wiring plug, and then connected to the external threads of the CAN plug on the four-core CAN bus plug; There are sealing ridges on the upper cover plate, and there is a middle frame embedding groove on the hexagonal middle frame. During installation, first inject strong sealing glue into the middle frame embedding groove, and the sealing ridge (1-3) of the upper cover plate (1) just presses into the middle frame embedding groove; Seven light-emitting diode indicators are placed at the central position of the upper cover plate to centrally indicate the operating conditions of the high-speed switch; There are hexagonal reinforcing ribs on the bottom plate, and there is a junction box groove on the explosion-proof junction box.

This equipotential line is connected to the explosion-proof junction box and then grounded at a single point uniformly, thus completely eliminating the circulating current impact caused by accidental multiple grounding.

[0019] Furthermore, the hexagonal middle frame (2) and the explosion-proof junction box (3) are both made of aluminum alloy material and are subjected to metal anodizing post-treatment.

Among them, when the light-emitting diode is lit, it is valid, and when it is extinguished, the state fails.

[0021] Furthermore, the model of the AI microprocessor (5-1) supported on the PCB circuit board (5) is ESP32-S3, which is a domestic high-performance dual-core processor using QFN56 packaging, supports Bluetooth and WiFi functions, and uses a low-power supply method.

It realizes the operations of digging holes, slotting, and building walls through the central separation hole (3-6) of the junction box to overcome the influence of distributed capacitance and induced static electricity. Beneficial effects

[0025] The multi-modal DC power high-speed switch supporting artificial intelligence technology proposed by the present invention has the following remarkable beneficial effects: 1. In the topological space design of the multi-modal DC power high-speed switch supporting artificial intelligence technology, the explosion-proof junction box and the power switch are actually combined into one and form the main body skeleton part, thus smoothly solving the following five problems: First, the wiring problem of the cable; second, the connection problem existing in the interface between the dual CAN bus and the switch; third, solving the heat dissipation problem of high-power MOS devices under high-power conditions. The most obvious way is that the PCB circuit board solves its heat dissipation problem under high current by the MOS tube soldered on the PCB circuit board leaning against the hexagonal middle frame of the aluminum profile; fourth, the junction box supports the equipotential wiring channel, thus completely eliminating the possibility of accidental multiple grounding of the system and the influence of the potential difference caused by multiple grounding on the induced circulating current, because it allows multiple DC electrical equipment to be grounded at a single point uniformly after passing through the junction box, thus greatly increasing the reliability of the system against electric leakage; fifth, the junction box is designed with an explosion-proof multi-channel outlet, thus facilitating the multi-modal upgrade under artificial intelligence technology and greatly expanding the application range of the multi-modal DC power high-speed switch.

[0026] 2. More importantly, by integrating dual CAN buses into the high-speed power switch, the technological upgrade of the power switch of the present invention by artificial intelligence technology is strengthened. Among them, one CAN bus for standard eight-bit data packets communicates with the internal microprocessor; the other is an extended CAN FD bus for 64-bit data packets, which can communicate with the host computer through networking, thus ensuring that the high-speed power switch also becomes a node for local area network communication. Through API (Application Programming Interface) interaction, it can be upgraded to an intelligent general-purpose robot with deep learning capabilities and scalability under multi-modal algorithms. Even the health status of the lithium battery pack can be published to the host computer through the CAN FD bus, and an analysis report on the remaining power (SOC) and power factor analysis report can be provided to the customer in a timely manner. Especially when there is a system leakage, the leakage information or power-off reason information can be transmitted in a timely manner through the CAN bus, thus opening up a particularly valuable innovation field when the new energy market and the digital civilization era are approaching.

[0027] 3. The multi-modal DC power high-speed switch supporting artificial intelligence technology is no longer a single switch component, and it also hides completely unexpected black technologies. Because its microsecond-level fast response ability indicates that it can cut off the power supply within an extremely short time, which is faster and more reliable than the protection device with electromagnetic tripping. Therefore, it is particularly suitable for power switching of new energy lithium battery packs to protect the safety of personnel and electrical equipment.

[0028] 4. More importantly, the operating current of this high-speed power switch reaches the level of hundreds of amperes, so it can replace the conventional high-power zero-point leakage protector. Since there is an input digital current transformer and three output digital current transformers inside the circuit, it can detect whether the input current and output current in the circuit are balanced with extremely high sensitivity, and closely monitor the balance state of the on-line current, so as to accurately judge whether there is a leakage phenomenon in the system. If there is no leakage, the vector sum of the current is zero; if there is a leakage or a small leakage current, the current balance will be broken, and the power switch will quickly respond to cut off the power supply, preventing the risk of electric shock or fire caused by lithium battery explosion with a precautionary speed, thus achieving the purpose of zero-point leakage protection. Obviously, the multi-modal DC power high-speed switch supporting artificial intelligence technology can be widely applied to large mobile devices such as electric vehicles, and can effectively reduce the incidence of accidental electrical accidents.

[0029] 5. In the multi-modal DC power high-speed switch supporting artificial intelligence technology, due to the existence of three output digital current transformers, it shows that this multi-modal DC power high-speed switch supporting artificial intelligence technology can also group and partition the output power supply, thus further promoting the intelligent management level of system power consumption.

[0030] 6. Particularly importantly, all components in the multimodal DC power high-speed switch supporting artificial intelligence technology are domesticated. Even the core microcontroller chip is the ESP32-S3, a domestic chip supporting AI accelerated inference ability. In the DeepSeek mode, through the standard CAN interface, the resident code in the ESP32-S3 can be rewritten online, or its AI model can be converted into the format of an embedded device, thus upgrading its DC power high-speed switch fantastically into a node post on the information highway.

[0031] 7. The multimodal DC power high-speed switch supporting artificial intelligence technology adopts a dual CAN layout, so it supports the power supply and distribution system of a large-scale container local area network under the new energy system. It should be particularly stated that this switch supports the management of distributed container energy storage power stations. By means of simple on-off operations, electrical energy can be stored (charged) when the power demand is low and released (discharged) during peak hours to cut the peak load of the power system and reduce the power cost.

[0032] 8. Since the actuator of the multimodal DC power high-speed switch supporting artificial intelligence technology abandons the traditional electromagnetic circuit and adopts contactless high-speed MOS devices, there is no electromagnetic arcing phenomenon at the moment of switch action, and thus no electrocorrosion between contacts occurs. Therefore, the service life of the high-speed switch is extended extremely well.

[0033] The above is the preferred implementation of the present invention. In this specification, the principle and implementation of the present invention are elaborated through specific examples, which are only used to help engineers and technicians in this field understand the core idea of the present invention and should not be misinterpreted as a limitation of the present invention. Those skilled in the art understand that all changes made to the present invention in form and detail without departing from the spirit and scope of the present invention defined by the appended claims are within the protection scope of the present invention.
