Description

Intelligent distribution box and signal transmission method Technical Field

[0001] The present invention belongs to the technical field of intelligent distribution boxes, and particularly relates to an intelligent distribution box and a signal transmission method. Background Art

[0002] As more and more electrical appliances enter the consumer market, while bringing convenience to consumers' lives, they also pose safety hazards. How to proactively ensure electricity safety has become a topic of widespread concern in society. The existing method usually solves this problem through circuit breakers. Circuit breakers automatically trip to protect the circuit when a short circuit, overload, etc. occur in the circuit. However, when a short circuit or overload occurs in the circuit, the safety hazard already exists, and the circuit breaker tripping cannot eliminate this hazard. Therefore, an intelligent distribution box has emerged, which connects the traditional circuit breaker to a central processing unit through a data cable. The central processing unit analyzes the circuit data for proactive protection. This solution provides better protection for electricity safety in terms of technical thinking. Technical issues

[0003] However, in actual cases, a distribution box usually contains multiple electrical components including circuit breakers. Each electrical component needs to be data connected at the same time as the electrical connection. In order to avoid the circuit being too complicated, the data connection between adjacent electrical components is carried out in series. The disadvantage is that as long as there is a poor contact or disconnection in the connection method of one electrical component, the data information of all subsequent electrical components will not be able to be returned to the central processing unit, that is, the central processing unit cannot provide protection for electrical components without data information. Therefore, how to ensure the stable and reliable data transmission between each electrical component and the central processing unit has become a technical problem that technical personnel in this field urgently need to solve. Technical Solutions

[0004] Based on the above technical problems, the present invention proposes an intelligent distribution box. By designing a new structure of various electrical components including circuit breakers, the concave end surface connected to the guide rail can be connected to the circuit board embedded with power lines and data lines installed in the groove of the guide rail, so that each electrical component can independently feed back circuit data to the central processor, ensuring power safety.

[0005] In order to achieve the above technical objectives, the present invention adopts the following technical solutions.

[0006] An intelligent distribution box includes multiple electrical components, the electrical components including at least a common power supply module for providing electronic circuit working power to each electrical component, a main input intelligent circuit breaker for connecting to an external strong power source and distributing an internal strong power source; at least one branch intelligent circuit breaker connected to the main input intelligent circuit breaker; a central processing unit connected to the main input intelligent circuit breaker and the branch intelligent circuit breaker, for receiving and processing circuit data fed back by the main input intelligent circuit breaker and the branch intelligent circuit breaker, and sending execution instructions to the main input intelligent circuit breaker and the branch intelligent circuit breaker; and at least one standard guide rail fixed in the distribution box for mounting the electrical components. The box is characterized by comprising:

[0007] At least one PCB circuit board is mounted in the groove of the standard guide rail, and is embedded with a plurality of printed parallel wires, including at least one set of power lines and one set of data lines, for realizing parallel connection between circuits and / or data lines between various electrical components;

[0008] Elastic contacts, used to connect various electrical components and printed parallel conductors on the PCB circuit board;

[0009] An open slot is located on the guide rail slot where each electrical component is connected to the standard guide rail, and is used to allow one end of the elastic contact to be connected to the interior of each electrical component, and then the other end to pass through the open slot to contact the printed parallel wires on the PCB circuit board;

[0010] The processor is installed inside each electrical component and is used to transmit the processed circuit data in each electrical component to the central processing unit through the data line, and to process the instructions issued by the central processing unit and pass them to each electrical component.

[0011] Furthermore, the intelligent distribution box also includes a plastic support plate installed in the groove of the standard guide rail to provide support for the PCB circuit board.

[0012] Furthermore, a connector is provided at each end of the PCB circuit board, and the circuit on the connector completely corresponds to the printed parallel wires on the PCB circuit board, and is used to connect the printed parallel wires of the two PCB circuit boards.

[0013] Furthermore, it also includes a plug, which is connected to the connector to achieve communication between PCB circuit boards in the same row.

[0014] Furthermore, when there are at least two rows of standard guide rails for placing electrical components in the intelligent distribution box, it also includes a flexible wire row, which is connected to the connector to achieve connectivity between the rows of PCB circuit boards.

[0015] Furthermore, the intelligent distribution box also includes a network communication module, which is connected to the central processing unit and is used for the central processing unit to transmit circuit data to the outside and receive external instructions.

[0016] Furthermore, the circuit data includes at least current data, voltage data, temperature data, and working status data.

[0017] A signal transmission method for an intelligent distribution box, applied to an intelligent circuit breaker, includes:

[0018] Transmit its own circuit data to the central processing unit in real time;

[0019] Receives control instructions from the central processing unit and performs corresponding actions according to the control instructions.

[0020] Furthermore, the control instructions include at least an opening instruction and a closing instruction; and the executing corresponding actions include at least executing an opening action and executing a closing action.

[0021] A signal transmission method for an intelligent distribution box, applied on a central processing unit, comprises:

[0022] Receive circuit data fed back by each electrical component and transmit the circuit data of each electrical component to an external control terminal;

[0023] And, receiving the control instruction sent by the external control terminal, and sending the control instruction to the corresponding electrical component. Beneficial effects

[0024] The beneficial effects of the present invention lie in the following: by designing a PCB circuit board that allows electrical circuits and data lines to be embedded within it and placed within the grooves of a standard guide rail, the structure of electrical components such as circuit breakers is redesigned, with grooves cut into the concave end surfaces (guide rail grooves) where they connect to the guide rails, allowing elastic contacts to connect to the PCB circuit board through the grooves after connection to the circuit breaker or other electrical component. Furthermore, a processor for data processing is added to each electrical component, allowing a common power supply module to provide power to each electrical component, and circuit data from each electrical component is processed by the processor and fed back to a central processing unit via a data line. When the central processing unit determines that a particular electrical component may pose a safety hazard, it issues a control command such as opening or closing the circuit. Each electrical component exchanges data with the central processing unit via the PCB circuit board, and the parallel connections do not affect each other, ensuring stable and reliable connections and ensuring electrical safety. Furthermore, when a distribution box contains multiple rows of circuit breaker circuits, the PCB circuit boards in each row can be connected in series via connectors and flexible cable strips, ensuring that all circuit breakers in the entire distribution box can independently exchange data with the central processing unit. Moreover, the central processing unit can also transmit data to the external control end through the network communication module and receive instructions issued by the external control end to control various electrical components, so as to provide multiple security guarantees for data analysis and processing. Alternatively, the external control end can directly issue forced control instructions to the central processing unit to control the operation of various electrical components, thereby multiple protections for electricity safety.

Best Mode for Carrying Out the Invention

[0035] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. 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 making creative efforts are within the scope of protection of the present invention.

[0036] The structures, proportions, sizes, etc. illustrated in the drawings of this specification are only used to match the contents disclosed in the specification so that people familiar with this technology can understand and read them. They are not used to limit the conditions for the implementation of the present invention and therefore have no substantial technical significance. Any modification of the structure, change in the proportional relationship or adjustment of the size should still fall within the scope of the technical content disclosed by the present invention without affecting the efficacy and purpose of the present invention. At the same time, the terms such as "upper", "lower", "left", "right", "front", "back", "middle" and "one" quoted in this specification are only for the convenience of description and are not used to limit the scope of the implementation of the present invention. Changes or adjustments in their relative relationships should also be regarded as the scope of the implementation of the present invention without substantially changing the technical content.

[0037] It should be noted that the full English name of PCB circuit board is: Printed Circuit Board, also called printed circuit board or printed circuit board, which is a component frequently used by technicians in the electrical field.

[0038] As shown in Figure 1-2.

[0039] An intelligent power distribution box includes multiple electrical components, including at least a common power supply module 2 for providing electronic circuit power to each electrical component, a main input intelligent circuit breaker 3 for connecting to an external strong power source and distributing internal strong power; at least one branch intelligent circuit breaker 4 connected to the main input intelligent circuit breaker 3; a central processing unit (not shown) connected to the main input intelligent circuit breaker 3 and the branch intelligent circuit breaker 4, for receiving and processing circuit data fed back by the main input intelligent circuit breaker 3 and the branch intelligent circuit breaker 4, and sending execution instructions to the main input intelligent circuit breaker 3 and the branch intelligent circuit breaker 4; and at least one standard guide rail 1 fixed in the power distribution box for mounting electrical components.

[0040] It should be noted that a network communication module (not shown) is further included, which is connected to the central processing unit and is used for the central processing unit to transmit circuit data to the outside and receive external instructions.

[0041] It should be noted that the standard guide rail 1 is a metal rail commonly used in distribution boxes for installing electrical components such as circuit breakers. Its size is usually standard and is well known to those skilled in the art. The common power supply module 2 provides power for the operation of each electrical component, generally a DC power supply. One end of the main input intelligent circuit breaker 3 is connected to the external AC power supply, and then the power is distributed to each branch intelligent circuit breaker 4. Each branch intelligent circuit breaker 4 is usually directly connected to the load; the central processing unit is usually a chip, and it and the network communication module are usually installed in an electrical box.

[0042] It should be further explained that in a specific implementation, there is no distinction between main input and branch circuits for circuit breakers. External lines are directly connected to each circuit breaker, or there is only one circuit breaker in the distribution box, which is also applicable to this solution.

[0043] An intelligent distribution box further includes at least one PCB circuit board 5, which is mounted in a groove of a standard guide rail 1 and has a plurality of printed parallel wires embedded therein, including at least one set of power lines and one set of data lines, for realizing parallel connection between circuits and / or data lines between various electrical components;

[0044] It should be noted that the PCB circuit boards 5 typically utilize standard dimensions and are provided with a connector 9 at each end. As shown in FIG3 , the wiring on the connector 9 completely corresponds to the printed parallel conductors on the PCB circuit boards 5. Therefore, in one embodiment, when the length range of the electrical components mounted on the standard guide rail 1 exceeds the length of the PCB circuit boards 5, connectivity between the PCB circuit boards in the same row can be achieved by connecting the connector 9 and the plug 11. Of course, another possibility is that, in one embodiment, the distribution box is equipped with several rows of standard guide rails 1, each of which is equipped with electrical components that need to be connected. Then, a flexible cable row 10 can be used to connect the PCB circuit boards 5 on each row of standard guide rails 1 in series, thereby ensuring that all electrical components connected to the PCB circuit boards 5 can communicate with the central processing unit.

[0045] It should be noted that the intelligent distribution box further includes a plastic support plate 8 , as shown in FIG4 , which is installed in the groove of the standard guide rail 1 to provide support for the PCB circuit board 5 .

[0046] As shown in Figure 5-7.

[0047] Elastic contact pieces 6, used to connect various electrical components and printed parallel wires on the PCB circuit board;

[0048] It should be noted that the number of elastic contacts 6 is usually equal to the total number of circuits and / or data lines on the PCB circuit board 5. For example, in one embodiment, if two power lines and four data lines are embedded on the PCB circuit board 5, then there should also be six elastic contacts on the electrical device.

[0049] It should be further explained that, as shown in Figure 6B, the elastic contact 6 is in state ① during installation. When the electrical component is installed on the standard guide rail 1, the elastic contact 6 is compressed and presents state ②. At this time, the elastic contact 6 and the PCB circuit board 5 are tightly fitted. The elastic pressure of the elastic contact 6 itself ensures that the electrical component and the PCB circuit board 5 can always maintain circuit connectivity.

[0050] An opening slot 7 is located on the guide rail slot where each electrical component is connected to the standard guide rail, and is used to allow one end of the elastic contact piece 6 to be connected to the interior of each electrical component, and then the other end to pass through the opening slot to contact the printed parallel wires on the PCB circuit board;

[0051] It should be noted that, under normal circumstances, the concave end surface where the electrical component is connected to the standard guide rail 1 is called a guide rail groove. There is no groove on the guide rail groove of the existing electrical component. In order to enable the electrical component to be connected to the PCB circuit board 5 located on the standard guide rail 1, it is necessary to open an open groove 7 on the concave end surface where the electrical component is connected to the standard guide rail 1. That is, traditional electrical components cannot be used in this solution. Under normal circumstances, the number of open grooves 7 corresponds to the number of elastic contact pieces 6. For example, in one embodiment, an electrical component is equipped with 6 elastic contact pieces, then it should have 6 open grooves 7. Of course, according to the needs of use, a long groove can be directly opened on the electrical component for installing and passing 6 elastic contacts, or 2 long grooves can be opened according to the power line and data line.

[0052] It should be noted that, in order to be applied to this solution, all electrical device modules installed in this solution need to have opening slots 7 and elastic contacts 6 installed to achieve circuit connection and data exchange, such as circuit breakers, controllers, switches, etc.

[0053] The processor (not shown) is installed inside each electrical component and is used to transmit the processed circuit data in each electrical component to the central processor through the data line, and to process the instructions issued by the central processor and transmit them to each electrical component.

[0054] It should be noted that, in one embodiment, the processor is mainly installed inside the main input intelligent circuit breaker 3 and the branch intelligent circuit breaker 4, and is a data conversion unit for each circuit breaker to exchange data with the central processor. It has at least encoding and decoding capabilities, and encodes all circuit data such as current data, voltage data, temperature data, working status data, etc. in each circuit breaker and transmits them to the central processor. At the same time, the processor can decode digital instructions issued by the central processor and control each circuit breaker to perform related actions according to the control instructions.

[0055] As shown in Figure 8.

[0056] A signal transmission method for an intelligent distribution box, applied to an intelligent circuit breaker, includes:

[0057] Step m1: transmit its own circuit data to the central processing unit in real time;

[0058] Step m2: Receive the control instruction sent by the central processing unit and execute the corresponding action according to the control instruction.

[0059] Furthermore, the control instructions include at least an opening instruction and a closing instruction; and the executing corresponding actions include at least executing an opening action and executing a closing action.
