Description

Technical Field

[0001] The present application relates to the technical field of power distribution cabinets, and in particular to a power distribution cabinet based on near field communication. Background Art

[0002] A distribution cabinet is a general term for motor control centers. Distribution cabinets are used in applications with dispersed loads and a small number of circuits, while motor control centers are used in applications with concentrated loads and a large number of circuits.

[0025] Embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although certain embodiments of the present disclosure are shown in the accompanying drawings, it should be understood that the present disclosure can be implemented in various forms and should not be construed as limited to the embodiments described herein. Rather, these embodiments are provided to provide a more thorough and complete understanding of the present disclosure. It should be understood that the drawings and embodiments of the present disclosure are for illustrative purposes only and are not intended to limit the scope of protection of the present disclosure.

[0026] It should also be noted that, for ease of description, only the parts related to the invention are shown in the drawings. In the absence of conflict, the embodiments and features in the embodiments of the present disclosure may be combined with each other.

[0027] It should be noted that the concepts of "first" and "second" mentioned in this disclosure are only used to distinguish different devices, modules or units, and are not used to limit the order or interdependence of the functions performed by these devices, modules or units.

[0028] It should be noted that the modifications of "one" and "multiple" mentioned in the present disclosure are illustrative rather than restrictive, and those skilled in the art should understand that unless otherwise clearly indicated in the context, they should be understood as "one or more".

[0029] The names of the messages or information exchanged between multiple devices in the embodiments of the present disclosure are only used for illustrative purposes and are not used to limit the scope of these messages or information.

[0030] The present disclosure will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments.

[0031] Reference Figures 1 to 3 As shown, the power distribution cabinet 100 based on near-field communication of the present application includes: a cabinet body 101 , a cabinet door 102 , an electronic door lock 103 , a first type of near-field tag 104 , a second type of near-field tag 105 , and a controller 107 .

[0032] The cabinet 101 is formed with a cabinet space for accommodating electrical components; the cabinet door 102 is rotatably connected to the cabinet 101 to open or close the cabinet space; an electronic door lock 103 is fixed to the cabinet door 102 to lock the relative position of the cabinet door 102 and the cabinet 101; a first-type near-field tag 104 is electrically connected to the electronic door lock 103 to send a lock or unlock signal to the electronic door lock 103; wherein the first-type near-field tag 104 is fixedly mounted on the inner side of the cabinet door 102. The first-type near-field tag 104 and the second-type near-field tag 105 are both NFC tags.

[0033] Reference Figure 1 As shown, controller 107 is electrically connected to first-type near-field tag 104 and second-type near-field tag 105, respectively. Controller 107 is fixed to the inside of cabinet door 102. Controller 107 is used to implement control functions and may include a single-chip microcomputer and remote communication capabilities. Its functions and implementation techniques are well known in the art and will not be elaborated upon here.

[0034] The plurality of first-type proximity tags 104 are positioned at different locations on the cabinet door 102. This provides the advantage of exchanging distance information with different first-type proximity tags 104 to unlock the door based on the movement trajectory of the mobile terminal 108. In other words, if a user interacts with each of the first-type proximity tags 104 using the NFC function of the mobile terminal 108 in a predetermined order, the user is deemed to have permission to unlock the door.

[0035] The NFC-based distribution cabinet 100 includes an odd number of first-type NFC tags 104 ; and the first-type NFC tags 104 are offset relative to the cabinet door 102 so that a symmetrical sequence is not generated, thereby affecting the accuracy of door opening and unlocking.

[0036] Reference Figure 1 As shown, as a specific solution, the electronic door lock 103 and the controller 107 are arranged between the two first-type near-field tags 104. This can make the connection between the electronic door lock 103 and the controller 107 and the first-type near-field tags 104 as short as possible.

[0037] Reference Figures 1 to 3 As shown, the second type of near-field tag 105 is installed on the inner wall of the cabinet 101; wherein, the distribution cabinet 100 based on near-field communication includes multiple second type of near-field tags 105; the second type of near-field tag 105 is set on the side wall of the cabinet 101 opposite to the cabinet door 102.

[0038] Reference Figure 3As shown, a part of the NFC tags (first type near-field tags 104) of the present application can be moved on the cabinet door 102, thereby forming a moving coordinate system, and another part of the NFC tags (second type near-field tags 105) are fixed, so that the movement of the cabinet door 102 can be known, which also helps to control the locking timing of the electronic door lock 103.

[0039] The improvement of the present application lies in the locations where the first type of near-field tag 104 and the second type of near-field tag 105 are arranged. The present application does not rely on specific software and control methods.

[0040] The above descriptions are merely some preferred embodiments of the present disclosure and illustrate the underlying technical principles. Those skilled in the art should understand that the scope of the invention encompassed by the embodiments of the present disclosure is not limited to technical solutions formed by specific combinations of the aforementioned technical features. It also encompasses other technical solutions formed by any combination of the aforementioned technical features or their equivalents, without departing from the aforementioned inventive concept. For example, a technical solution formed by replacing the aforementioned features with (but not limited to) technical features with similar functions disclosed in the embodiments of the present disclosure.
