Description

Technical Field

[0001] This invention relates to the field of automatic control technology, and in particular to a method for setting up a sensing device, a control method, and a refrigeration device. Background Technology

[0002] Devices configured with a cabinet and a door, particularly the upright freezers provided in the prior art, typically have a sensor and a cooperating device between the door and the cabinet. The device is opened by transmitting signals between these two devices. However, with the increasing popularity of devices that can open from different directions, especially with the development of side-by-side refrigerators, the existing method of simply placing sensors and cooperating devices on one side of the door and cabinet is insufficient to achieve the desired effect. Current technology only triggers the refrigerator when one side of the door is opened; when the user switches to the other side, no signal exchange occurs between the sensor and the cooperating device, thus failing to trigger the refrigerator. Therefore, providing a sensing device setting method, control method, and sensing system for bidirectional symmetrical door opening devices, so that the refrigerator responds when the user opens the door from different directions, has become an urgent technical problem to be solved. Summary of the Invention

[0003] One of the objectives of this invention is to provide a sensing device setting method to solve the technical problems of trigger failure and inability to trigger in a cascading manner when the sensing device setting method is applied to a bidirectional symmetrical door opening device in the prior art.

[0004] One of the objectives of this invention is to provide a method for controlling a sensing device.

[0005] One of the objectives of this invention is to provide a refrigeration device.

[0006] To achieve one of the above-mentioned objectives, one embodiment of the present invention provides a sensing device setting method applied to a bidirectional symmetrical door opening device, comprising: configuring multiple sets of centrally symmetrical and linearly arranged distance sensing elements in the symmetrical door opening direction of the cabinet or door; configuring triggering conditions for each set of distance sensing elements and corresponding control commands after triggering, wherein the triggering conditions include Boolean operation relationships for each set of distance sensing elements; wherein the Boolean operation relationship for the first set of distance sensing elements farther from the center point is OR, and the Boolean operation relationship for the second set of distance sensing elements closer to the center point is S.

[0007] As a further improvement of one embodiment of the present invention, the method further includes: configuring the control commands corresponding to the first group of distance sensing elements to be different from the control commands corresponding to the second group of distance sensing elements.

[0008] As a further improvement of one embodiment of the present invention, the method further includes: setting the center line of the crossbeam or vertical beam of the housing as the center symmetry line of the distance sensing element.

[0009] As a further improvement of one embodiment of the present invention, the method further includes: a distance sensing element disposed on the central symmetry line.

[0010] To achieve one of the above-mentioned objectives, one embodiment of the present invention provides a sensing device control method applied to a bidirectional symmetrical door opening device, comprising: receiving signals from a first group of distance sensing elements, determining whether the first group of distance sensing elements meets a trigger condition, and if so, executing a preset control command corresponding to the first group of distance sensing elements; and receiving signals from a second group of distance sensing elements, determining whether the second group of distance sensing elements meets a trigger condition, and if so, executing a preset control command corresponding to the second group of distance sensing elements; wherein the first group of distance sensing elements and the second group of distance sensing elements are symmetrically arranged in a straight line in the symmetrical door opening direction of the cabinet or door, and the trigger condition includes a Boolean operation relationship for each group of distance sensing elements, wherein the Boolean operation relationship for the first group of distance sensing elements farther from the center point is OR, and the Boolean operation relationship for the second group of distance sensing elements closer to the center point is S.

[0011] As a further improvement of one embodiment of the present invention, the distance sensing element is configured to be symmetrical about the center line of the crossbeam or vertical beam of the housing.

[0012] As a further improvement of one embodiment of the present invention, the method further includes: when a signal is received from a third distance sensing element, executing a preset control command corresponding to the third distance sensing element; wherein the third distance sensing element is disposed on the central symmetry line.

[0013] To achieve one of the above-mentioned objectives, one embodiment of the present invention provides a refrigeration device, comprising: a cabinet and a door, the cabinet and the door being configured to implement bidirectional symmetrical opening; a sensing device, the sensing device comprising multiple sets of centrally symmetrical distance sensing elements arranged in a straight line along the symmetrical opening direction of the cabinet or the door, wherein the distance between the first set of distance sensing elements and the center point is greater than the distance between the second set of distance sensing elements and the center point; and a control unit, the control unit being configured to execute a preset control command corresponding to each set of sensing elements meeting a trigger condition, the trigger condition including a Boolean operation relationship of each set of distance sensing elements, wherein the Boolean operation relationship of the first set of distance sensing elements is OR, and the Boolean operation relationship of the second set of distance sensing elements is AND.

[0014] As a further improvement of one embodiment of the present invention, the control unit includes a communication unit, a judgment unit, and an execution unit that are electrically connected in sequence. The communication unit is connected to the plurality of distance sensing elements respectively. The judgment unit is used to determine whether each group of distance sensing elements meets the triggering condition. The execution unit is used to execute a preset control command. The cooling device also includes a lighting device and a cooling fan that are electrically connected to the execution unit.

[0015] As a further improvement of one embodiment of the present invention, the plurality of distance sensing elements are disposed on the crossbeams or vertical beams of the housing, and are configured to be symmetrical about the center line of the crossbeams or vertical beams. A third distance sensing element electrically connected to the communication unit is also disposed on the center line of the symmetrical arrangement. The distance sensing element is configured as a magnetic switch.

[0016] Compared with the prior art, the sensing device setting method provided by the present invention sets multiple sets of distance sensing elements at one of the door body and the cabinet body, and configures the distance sensing elements to have special positional relationships and triggering logic, so as to achieve the effect that opening the door from both sides can trigger the bidirectional symmetrical door opening device to execute the corresponding control commands respectively. At the same time, since at least two sets of distance sensing elements are configured to have different positional relationships relative to the center point, the technical effect of hierarchical triggering of control commands is further realized.

[0023] The present invention will now be described in detail with reference to the specific embodiments shown in the accompanying drawings. However, these embodiments do not limit the present invention, and any structural, methodological, or functional modifications made by those skilled in the art based on these embodiments are included within the scope of protection of the present invention.

[0024] It should be noted that the term "comprising" or any other variation thereof is intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, apparatus, or apparatus. Furthermore, the terms "first," "second," "third," "fourth," "fifth," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0025] One embodiment of the present invention provides a refrigeration device, such as... Figure 1 As shown, the refrigeration device includes a sensing device 300 and a control unit 400. The control unit 400 is electrically connected to the sensing device 300 to control the sensing device 300 and / or receive signals from the sensing device 300. The control can be defined as controlling the sensing device 300 to start or stop sensing or detecting external parameters, or controlling the sensing device 300 to start or stop sending or acquiring data or parameters to the control unit 400. The receiving can be defined as the control unit 400 actively acquiring signals pre-stored by the sensing device 300, or the control unit 400 passively receiving signals transmitted from the sensing device 300.

[0026] Furthermore, the sensing device 300 specifically includes multiple sets of distance sensing elements. Here, "multiple sets" can be defined as including at least two sets of distance sensing elements, each set including at least two independently arranged distance sensing elements, thereby meeting the need to place it at different locations within the refrigeration equipment. Specifically, taking the sensing device 300 including two sets of distance sensing elements as an example, the sensing device 300 includes a first set of distance sensing elements 31 and a second set of distance sensing elements 32, and the first set of distance sensing elements 31 and the second set of distance sensing elements 32 are respectively connected to the control unit 400 to output signals to the control unit 400. The signal here has different definitions depending on the configuration of the distance sensing elements. For example, in an embodiment where the distance sensing element is configured to detect the distance value between its location and a relative object by transmitting and receiving one or more of infrared signals, acoustic signals, and other detection signals, the signal can be defined as the distance value, or it can be defined as a judgment result generated when the distance value is greater than a preset distance value; when the distance sensing element is configured as a switching element capable of generating binary codes, the signal can be configured as an on signal and an off signal.

[0027] Correspondingly, the control unit 400 is configured to execute a preset control command when the distance sensing element meets the trigger condition. The trigger condition is defined as the condition that the signal should meet when the corresponding control command is to be executed. When the signal has different definitions, the trigger condition referred to here can also have different definitions. Specifically, when the signal is defined as a judgment result generated based on a distance value, the trigger condition can be defined as one or more of several judgment results. When the signal is defined as a distance value, the trigger condition can be defined as a judgment step with a preset distance value. When the signal is defined as binary code, the trigger condition can be defined as one of a conduction signal and a cutoff signal, or one of the digits 1 and 0.

[0028] In this embodiment, the triggering condition further includes the determination of the signal combination generated by different sensing elements within each group of sensing elements. The triggering condition includes the Boolean operation relationship of each group of distance sensing elements, wherein the Boolean operation relationship of the first group of distance sensing elements 31 is OR, and the Boolean operation relationship of the second group of distance sensing elements 32 is AND. Abstractly speaking, when one of the several distance sensing elements in the first group of distance sensing elements 31 is triggered, the first group of distance sensing elements 31 is considered to satisfy the triggering condition; when all of the several distance sensing elements in the second group of distance sensing elements 32 are triggered, the second group of distance sensing elements 32 is considered to satisfy the triggering condition.

[0029] Specifically, taking the first group of distance sensing elements 31, which includes a first distance sensing element 311 and a second distance sensing element 312, and the second group of distance sensing elements 32, which includes a fourth distance sensing element 321 and a fifth distance sensing element 322, as an example, when the first group of distance sensing elements 31 meets the trigger condition, the control unit 400 receives a signal from at least one of the first distance sensing element 311 and the second distance sensing element 312, or a signal that meets the preset requirements. When the second group of distance sensing elements 32 meets the trigger condition, the control unit 400 simultaneously receives signals from both the fourth distance sensing element 321 and the fifth distance sensing element 322, or a signal that meets the preset requirements. It should be noted here that "receiving a signal" refers to an implementation where the distance sensing unit is configured to emit a signal only when the preset requirements are met.

[0030] At the structural design level, combined with Figure 1 and Figure 2As shown, the multiple sets of distance sensing elements included in the sensing device 300 are actually configured in this embodiment to be arranged in a straight line along the direction of the double doors on the cabinet 200 or the door 100 and are centrally symmetrical. The cabinet 200 and the door 100 are essential structures of the refrigeration equipment. The cabinet 200 and the door 100 are configured to implement bidirectional symmetrical opening. The door 100 can be selectively connected to the cabinet 200 by a rotational axis. When the cabinet 200 is arranged vertically, the direction of rotation of the door 100 can be configured to selectively open from top to bottom and from bottom to top, or selectively open from left to right and from right to left. Of course, the closing method and other combinations formed by the above opening and closing methods are readily conceived by those skilled in the art according to the embodiments provided by this invention.

[0031] The aforementioned arrangement along a straight line does not actually limit all distance sensing elements in the sensing device 300 to be on the same straight line. The distance sensing elements can be configured to oscillate discretely on both sides of a certain straight line, achieving the same desired technical effect. Furthermore, the term "central symmetry" does not mean that the pattern formed by connecting adjacent distance sensing elements must be strictly centrally symmetrical. In this embodiment, the distance sensing elements only need to be approximately evenly distributed on both sides of the same straight line, and symmetrical along a vertical or approximately vertical axis of symmetry, or along a center of symmetry (or center point) formed by the axis of symmetry and the same straight line. Various technical solutions derived from this can be anticipated.

[0032] In this embodiment, more specifically, the distance between the first group of distance sensing elements 31 and the center point is greater than the distance between the second group of distance sensing elements 32 and the center point. In the embodiment where the first group of distance sensing elements 31 and the second group of distance sensing elements 32 each have two distance sensing elements, the above scheme can also be interpreted as the distance between the first distance sensing element 311 and the second distance sensing element 312, which are symmetrically arranged with each other, is greater than the distance between the fourth distance sensing element 321 and the fifth distance sensing element 322, which are symmetrically arranged with each other.

[0033] Under this configuration, on the one hand, the feature of "multiple distance sensing elements being disposed on the housing 200 or the door 100" will be explained. The first distance sensing element 311 can be disposed on... Figure 2The distance sensing element can be located at the first position 311a of the housing or at the first position 311b of the door. It only needs to be configured to send and receive sensing signals to the other side to generate data to achieve the expected technical effect. At the same time, although this embodiment limits the multiple sets of distance sensing elements to be arranged in a straight line and at least each set of distance sensing elements forms a central symmetry, the distance sensing elements are actually set on the door 100 or the housing 200, which does not affect the realization of the expected technical effect of the present invention. In another embodiment, the first distance sensing element 311 and the second distance sensing element 312 are respectively disposed at the first position 311a and the second position 312a of the cabinet, and the fourth distance sensing element 321 and the fifth distance sensing element 322 are respectively disposed at the fourth position 321b and the fifth position 322b of the door; and in yet another embodiment, the first distance sensing element 311 and the fourth distance sensing element 321 are respectively disposed at the first position 311b and the fourth position 321b of the door, and the second distance sensing element 312 and the fifth distance sensing element 322 are respectively disposed at the second position 312a and the fifth position 322a of the cabinet.

[0034] On the other hand, the feature of "multiple sets of distance sensing elements arranged in a symmetrical opening direction" is explained. The definition of the symmetrical opening direction actually depends on the direction in which the door 100 opens. During the opening process, the door 100 rotates with the side connected to the housing 200 as the axis of rotation. The relative movement between the door 100 and the housing 200 creates a relative distance. During this process, the distance between the door 100 and the housing 200 near the axis of rotation remains approximately constant. Extending along the symmetrical opening direction from the axis of rotation, the farther away from the axis of rotation, the greater the distance between the corresponding positions on the door 100 and the housing 200. Ultimately, this results in the phenomenon that the spacing between the corresponding positions of the door 100 and the housing 200 in the symmetrical opening direction is not equal everywhere. The distance sensing element in this embodiment is set in this direction.

[0035] Continue as Figure 1As shown, the control unit 400 specifically includes a communication unit 41, a judgment unit 42, and an execution unit 43, which are electrically connected in sequence. The communication unit 41 is connected to the sensing device 300 and is specifically configured to be connected to multiple sets of distance sensing elements. The judgment unit 42 is used to further determine whether the distance sensing element meets the trigger condition based on the signal received by the communication unit 41 from the sensing device 300. The execution unit 43 is used to receive the judgment result from the judgment unit 42 and finally decide whether to execute the preset control command. In the refrigeration equipment provided by the present invention, a lighting device 21 and a refrigeration fan 22 are also specifically included. They are used to provide lighting for the refrigeration equipment when the cabinet 200 is opened through the door 100, and to provide refrigeration function for the refrigeration equipment when the cabinet 200 is closed by the door 100. The lighting device 21 and the refrigeration fan 22 are electrically connected to the execution unit 43 and are turned on and off by the preset control command executed by the execution unit 43.

[0036] Of course, the present invention is not limited to the above-described configuration of functions and connections. This is only a technical solution adapted to the usage scenario. In other embodiments, the execution unit 43 can also be connected to other devices in the refrigeration equipment, such as electrically driven drawers, bottle holders, or other storage devices that automatically extend and / or lift, or a mist generating device installed to prevent moisture loss from food inside the cabinet 200 after the door 100 is opened. At the same time, the specific control method for executing preset control commands to control devices in the refrigeration equipment or other devices outside the refrigeration equipment is not limited in the present invention. It can be applying high or low levels to the enable terminal of the control module in the device, or switching the electrical energy supplied to the device on and off.

[0037] In addition, such as Figure 1 As shown, in this embodiment, the sensing device 300 may further include a separately provided third distance sensing element 33. Unlike the first group of distance sensing elements 31 and the second group of distance sensing elements 32, the third distance sensing element 33 is separately provided and can be configured to have special functions, such as user detection or facial recognition. Alternatively, it can be configured to have the same function as the first group of distance sensing elements 31 and the second group of distance sensing elements 32—controlling other devices in the cooling equipment. When the third distance sensing element 33 meets the trigger condition, the execution unit 43 receives signals transmitted sequentially through the communication unit 41 and the judgment unit 42, and then executes a preset corresponding control command.

[0038] The control unit 400 may further include a separately provided storage unit 44. When the execution unit 43 receives the judgment result from the judgment unit 42, it retrieves the preset control command stored in the storage unit 44 and outputs the execution command to peripheral devices such as the lighting device 21 and the cooling fan 22, thereby achieving the control effect. Of course, in other embodiments, the storage unit 44 may be integrated with the execution unit 43. Alternatively, the communication unit 41, the judgment unit 42, the execution unit 43, and the storage unit 44 may all be integrated. The division of departments here is only for the convenience of functional description and does not limit the structural arrangement.

[0039] At the structural design level, such as Figure 2 As shown, in this embodiment, multiple sets of distance sensing elements are disposed on the horizontal or vertical beams of the housing 200, and configured with the center line of the horizontal or vertical beam as the central symmetry line. The third distance sensing element 33 is correspondingly disposed on this central symmetry line. In this way, the user can configure the control command corresponding to the rotation of the door 100 to the middle position to achieve the expected technical effect. It is worth noting that the horizontal or vertical beams mentioned here still depend on the rotation direction of the door 100 and the housing 200. When the housing 200 is arranged vertically and the door 100 is configured to open selectively from left to right and from right to left, the multiple sets of distance sensing elements are disposed on the horizontal beams of the housing 200; when the housing 200 is arranged vertically and the door 100 is configured to open selectively from top to bottom and from bottom to top, the multiple sets of distance sensing elements are disposed on the vertical beams of the housing 200.

[0040] In addition, the concepts of the center line and the central symmetry line, as mentioned above, do not strictly limit the multiple sets of distance sensing elements to mirror symmetry, axial symmetry, and central symmetry. Complete mirror symmetry is only a preferred implementation method, which can make the signal output more regular. At the same time, it should be understood that in the embodiment where the door 100 rotates to open around a hinge or other device with a certain volume or an extended length in the bi-directional symmetrical opening direction, the so-called center line in the preferred embodiment is configured as the axis of symmetry perpendicular to the bi-directional symmetrical opening direction, which is the remaining part of the horizontal or vertical beam after excluding the hinge or other device.

[0041] Furthermore, the multiple sets of distance sensing elements described in this invention can be specifically configured as magnetic switches. The magnetic switches include a switching element for outputting closing and opening signals to the communication unit 41, and a magnetic element for generating a magnetic field to affect the switching on and off of the switching element. When the magnetic element approaches the switching element, the generated magnetic field causes the reed inside the switching element to close, thus turning the switching element on. When the magnetic element moves away from the switching element to a certain preset distance, the reed of the switching element loses the influence of the magnetic field and separates, thus turning the switching element off. Using the above principle, those skilled in the art can configure different preset distances according to usage needs and adjust the sensitivity of the magnetic switches to enable preset control commands to be executed in different relative position states of the door 100 and the housing 200.

[0042] In terms of specific arrangements, Figure 2 Taking the illustrated embodiment as an example, the first position 311a, second position 312a, third position 33a, fourth position 321a, and fifth position 322a of the housing described above can be further interpreted as the first switching element 311a of the first distance sensing element 311, the second switching element 312a of the second distance sensing element 312, the third switching element 33a of the third distance sensing element 33, the fourth switching element 321a of the fourth distance sensing element 321, and the fifth switching element 322a of the fifth distance sensing element 322. 2a. Correspondingly, the first position 311b, the second position 312b, the third position 33b, the fourth position 321b, and the fifth position 322b of the door body mentioned above can be further interpreted as the first magnetic element 311b of the first distance sensing element 311, the second magnetic element 312b of the second distance sensing element 312, the third magnetic element 33b of the third distance sensing element 33, the fourth magnetic element 321b of the fourth distance sensing element 321, and the fifth magnetic element 322b of the fifth distance sensing element 322.

[0043] Of course, on the one hand, the positional relationship of the aforementioned switching element and magnetic element on the housing 200 and door 100 can be interchanged or formed in different combinations, as long as the switching element is configured to be connected to the communication unit 41 and the positions of the switching element and magnetic element correspond to each other; on the other hand, the independent arrangement of magnetic elements is not a necessary technical feature of the present invention. The function of the magnetic element is to adjust the opening and closing action of the switching element, so it can be arranged as a strip extending along the symmetrical opening direction on the door 100 or housing 200, which can also achieve the expected technical effect. The embodiment shown in this embodiment, which sets the magnetic elements independently, is only a preferred embodiment, which can avoid mutual interference between magnetic fields and has a higher degree of accuracy.

[0044] Continue to Figure 2The bidirectional symmetrical door configuration between the door 100 and the housing 200 shown in the figure is described in detail. This invention provides an exemplary embodiment in which the door 100 includes a door shell, a door frame, a door liner, and a foam layer filling the cavity formed by the above structures to give the refrigeration equipment strong insulation performance. The housing 200 includes a crossbeam, a vertical beam, and at least one refrigeration chamber enclosed by the above structures. In an embodiment where the housing 200 is arranged vertically and the door 100 can be selectively opened from right to left and from left to right, multiple sets of distance sensing elements are disposed at the crossbeam 20, and the door liner 10 corresponding to the crossbeam 20 may be provided with… The crossbeam 20 is equipped with a cooperating device corresponding to the multiple sets of distance sensing elements. The crossbeam 20 includes an opening side 201 and a hinge side 202. The door liner 10 includes a door rotating side 101 and a door fixed side 102. The door liner 10 is selectively pivotally connected to the hinge side 202 of the crossbeam 20 through the door fixed side 102. By rotating, a gap is created between the door rotating side 101 and the opening side 201. The user can enter the front of the box 200 through this gap to retrieve items. At the same time, the opening side 201 and the door rotating side 101 can also be selectively pivotally connected. The door fixed side 102 and the hinge side 202 are in a corresponding contact and relative limiting relationship, thereby creating a gap sufficient for the user to pass through during rotation.

[0045] Specifically, in this embodiment, a first switch element 311a, a fourth switch element 321a, a third switch element 33a, a fifth switch element 322a, and a second switch element 312a are sequentially arranged on the crossbeam 20 in the direction extending from the opening side 201 to the hinge side 202. A first magnetic element 311b, a fourth magnetic element 321b, a third magnetic element 33b, a fifth magnetic element 322b, and a second magnetic element 312b are sequentially arranged on the door liner 10 in the direction extending from the door rotating side 101 to the door fixed side 102. Thus, when the user holds the door rotating side 101 and opens the refrigeration device from right to left, the spacing of the mating structure of the first distance sensing element 311 is greater than that of the fourth distance sensing element 321, the third distance sensing element 33, the fifth distance sensing element 322, and the second distance sensing element 312. Correspondingly, when the user holds the door fixed side 102 and opens the refrigeration device from left to right, the size relationship of the above-mentioned spacing of the mating structures of different distance sensing elements is reversed.

[0046] Continuing, the Boolean operation relationship between the first distance sensing element 311 and the second distance sensing element 312 is configured as OR. Since one of the first distance sensing element 311 and the second distance sensing element 312 will always meet the signal transmission condition first, regardless of which direction the user opens the cooling device, the control command corresponding to the first set of distance sensing elements 31 can be triggered and executed under the expected state. In this embodiment, that is, the lighting device 21 is lit when the door 100 is opened at a small angle. At the same time, the Boolean operation relationship between the fourth distance sensing element 321 and the fifth distance sensing element 322 is configured as AND. Since one of the fourth distance sensing element 321 and the fifth distance sensing element 322 will always meet the signal transmission condition later, regardless of which direction the user opens the cooling device, it must be opened to a larger angle to trigger the execution of the control command corresponding to the second set of distance sensing elements 32. In this embodiment, that is, the cooling fan stops cooling when the door 100 is opened to a larger angle.

[0047] It should be emphasized here that, on the one hand, in this embodiment, the first set of distance sensing elements 31 is used to trigger the lighting device 21 to provide lighting when the door is opened at a small angle, and the second set of distance sensing elements 32 is used to stop the cooling fan 22 to save energy when the door is opened at a large angle. However, the specific functions can be replaced according to user needs. For example, when the refrigeration equipment is configured to have an automatic door opening function, when the small angle required by the first set of distance sensing elements 31 is met, the door opening motor can be driven to apply a torsional force to the door 100 and the housing 200, thereby helping the user to open the door; on the other hand, the definition of the large angle is as follows: Figure 2 Taking the right-to-left door opening embodiment as an example, the door 100 needs to rotate until the fifth distance sensing element 322 (the distance sensing element farther from the opening side 201 of the box 200) generates a disconnect signal before the preset control command corresponding to the second set of distance sensing elements 32 can be triggered. On the other hand, the embodiment described in this invention, which configures the Boolean operation relationship of the first set of distance sensing elements 31 as OR and the Boolean operation relationship of the second set of distance sensing elements 32 as AND, can be adjusted according to the needs of those skilled in the art. For example, in the bidirectional symmetrical door opening process, an embodiment is needed that triggers the preset control command when the door 100 is fully open or even forms a 90° angle with the box 200. In this case, the Boolean operation relationship of the first set of distance sensing elements 31 can be configured as AND.

[0048] Furthermore, the present invention provides a method for setting up a sensing device applied to a bidirectional symmetrical door opening device, such as... Figure 3 As shown, it includes:

[0049] Step 51: Configure multiple sets of centrally symmetrical and linearly arranged distance sensing elements in the symmetrical opening direction of the cabinet or door;

[0050] The symmetrical door opening direction, the central symmetry, and the linear arrangement mentioned above have all been explained in the preceding text and will not be elaborated upon again. However, the term "configuration" mainly refers to the method of setting up multiple sets of distance sensing elements. This invention does not limit the setting method; it can be achieved by gluing, structural limiting, and screwing. In this embodiment, since the distance sensing element is configured as a magnetic switch in the detailed embodiment, the magnetic element can be embedded in one side of the door 100 or the box 200, and blind holes are provided at intervals on the box 200 and the door 100. The switch element is then screwed into the blind holes. This ensures aesthetics while keeping at least the side of the switch element used for sensing exposed outside the box 200 or the door 100, resulting in a more sensitive sensing effect.

[0051] Step 52: Configure the trigger conditions for each group of distance sensing elements and the corresponding control commands after triggering.

[0052] In this invention, the triggering condition is configured to include at least the Boolean operation relationship of each group of distance sensing elements, and the Boolean operation relationship of the first group of distance sensing elements 31 that is farther from the center point is configured to be OR, and the Boolean operation relationship of the second group of distance sensing elements 32 that is closer to the center point is configured to be AND. The definitions of the first group of distance sensing elements 31, the second group of distance sensing elements 32, and the center point mentioned here are as described above. Boolean operations actually refer to the relationships of sum, or, not, equivalence, true, and false between different distance sensing elements in a single group. At the programming level, these relationships can also include not equal to, less than, greater than, less than or equal to, greater than or equal to, and XOR. In this embodiment, since a magnetic switch is used as the distance sensing element, and the magnetic switch is only used to output on and off signals, i.e., 1 and 0 signals, the technical solution provided by this invention only needs to include at least "sum" and "or" operations. Of course, in other embodiments of this invention, the distance sensing element is configured as an infrared distance sensor or an ultrasonic distance sensor that outputs a specific distance value. In this case, the Boolean operations can also include comparing the distance value output by each sensor with a preset distance value, thereby generating operations such as "greater than," "less than," "greater than or equal to," "less than or equal to," and "equal to." Those skilled in the art can obtain inspiration from this invention.

[0053] The control command is a selective output of different control signals after verifying whether the signal output by the distance sensing element satisfies a preset Boolean operation relationship. The form of this control signal is not limited. When the Boolean operation involves only two signals, 1 and 0, the output result is also only two, so the control command is configured to trigger or not trigger. When there are multiple types of Boolean operation objects, the output result may also be multiple, thus the control command can be configured to adjust between set levels. Furthermore, the control commands triggered for each group of distance sensing elements can be configured to be the same or different. Specifically, in this embodiment, the control commands corresponding to the first group of distance sensing elements 31 and the second group of distance sensing elements 32 can be configured to be different, thus achieving diversified functions.

[0054] In the above-described method of the present invention, the multiple sets of distance sensing elements can be set on the housing 200 and the door 100 at any position that satisfies the conditions of symmetrical door opening direction, central symmetry, and linear arrangement. Of course, this embodiment provides a specific setting method that uses the center line of the horizontal or vertical beam of the housing as the center symmetry line of the distance sensing element, which can achieve the technical effect of optimizing the neatness of the output signal of the distance sensing element and assisting the equipment or device to more accurately judge the opening degree of the door 100.

[0055] Furthermore, for the purpose of expanding functionality, an independent distance sensing element, namely the third distance sensing element 33 mentioned above, can also be provided on the central symmetry line. This allows for the configuration of corresponding functions when the door 100 is opened to the middle angle. In this embodiment, the functions corresponding to any of the aforementioned distance sensing elements are not specifically limited. All functions related to the opening angles of the door 100 and the housing 200 can be programmed and burned into either the execution unit 43 or the storage unit 44. In this embodiment, the programming and burning process should at least include a main program and an interrupt program that cooperates with the main program to output control commands. The main program should be configured to include at least a trigger condition judgment statement with Boolean operations and a loop statement. The interrupt program should at least include a result output statement for executing control commands.

[0056] In conjunction with the above-described extensions and limitations of the setting method provided in this embodiment, another embodiment of the present invention specifically provides a refined implementation method, such as... Figure 4 As shown, it includes:

[0057] Step 501: Set the center line of the crossbeam or vertical beam of the housing 200 as the center symmetry line of the distance sensing element;

[0058] Step 502: Set a distance sensing element on the central symmetry line;

[0059] Step 511: Configure multiple sets of centrally symmetrical and linearly arranged distance sensing elements in the symmetrical door opening direction of the cabinet;

[0060] Step 521: Configure the trigger conditions for each group of distance sensing elements and the corresponding control commands after triggering.

[0061] Based on the foregoing explanation, the technical effects produced by the steps of this detailed implementation method are expected and will not be repeated here.

[0062] Furthermore, the present invention provides a sensing device control method applied to a bidirectional symmetrical door opening device, such as... Figure 5 As shown, it includes:

[0063] Step 61: Receive the signal from the first group of distance sensing elements 31, determine whether the first group of distance sensing elements 31 meets the triggering condition, and if so, execute the preset control command corresponding to the first group of sensing elements 31.

[0064] Step 62: Receive the signal from the second group of distance sensing elements 32, determine whether the second group of distance sensing elements 32 meets the triggering conditions, and if so, execute the preset control command corresponding to the second group of distance sensing elements 32.

[0065] The first group of sensing elements and the second group of sensing elements are symmetrically arranged in a straight line in the symmetrical opening direction of the box or door. The triggering condition specifically includes the Boolean operation relationship of each group of distance sensing elements. The Boolean operation relationship of the first group of distance sensing elements 31, which is farther away from the center point, is OR, and the Boolean operation relationship of the second group of distance sensing elements 32, which is closer to the center point, is AND.

[0066] First, it should be noted that, regardless of whether it is the first group of distance sensing elements 31 or the second group of distance sensing elements 32, if the triggering condition is not met, the subsequent steps can be configured not to execute the corresponding preset control commands, so that the device cooperating with the execution unit 43 remains in its original working state. In this embodiment, considering that the door 100 and the cabinet 200 must also have a closed state in addition to the open state, in the closed state, control commands such as restarting the cooling fan 22 and turning off the lighting device 21, which are the opposite of those in the open state, should be executed in sequence, thus forming a control process that is more in line with the user's operating logic. Therefore, step 61 can also specifically include: if not, then execute the control command that is the opposite of the preset control command corresponding to the first group of sensing elements 31; step 62 can also specifically include: if not, then execute the control command that is the opposite of the preset control command corresponding to the second group of sensing elements 32.

[0067] Meanwhile, the order of steps 61 and 62 is not specifically limited in this invention. The content of step 61 is placed before the content of step 62 in the description because in this embodiment, the first group of distance sensing elements 31 is configured to be triggered before the second group of distance sensing elements 32. Therefore, this arrangement is made for the convenience of explanation. Those skilled in the art will understand that if the triggering order of the first group of distance sensing elements 31 and the second group of distance sensing elements 32 changes due to changes in position arrangement and control logic, the above order can be adjusted adaptively.

[0068] The following section further explains the signals, Boolean operations, and control commands at the device level, defining... Figure 2 In the multiple groups of distance sensing elements shown, the signal output by the distance sensing element located to the left of the center line is LS(i), and the signal output by the distance sensing element located to the right of the center line is RS(i), where i = 1, 2, ..., n, representing the group to which the distance sensing element belongs. There are a total of n groups of distance sensing elements. In the embodiment where the distance sensing elements are configured to output a conduction signal 1 and a cutoff signal 0, the signals satisfy:

[0069]

[0070] Wherein, l(i) represents the distance represented by the current position of the distance sensing element, specifically the distance between the magnetic element and the switching element, and L(0) represents the preset on / off distance. When the distance l(i) between the magnetic element and the switching element is greater than the on / off distance L(0), the distance sensing elements LS(i) and RS(i) output a 0 signal, and otherwise output a 1 signal.

[0071] Applying the above formula to this embodiment, we can obtain that the signals output by the second distance sensing element 312 and the first distance sensing element 311 of the first group of distance sensing elements 31 are LS(1) and RS(1) respectively, and the signals output by the fifth distance sensing element 322 and the fourth distance sensing element 321 of the second group of distance sensing elements 32 are LS(2) and RS(2) respectively. Applying the Boolean operation relationship described above to the above distance sensing elements, we can obtain that the first group of distance sensing elements 31 satisfies:

[0072] S(1) = LS(1)·RS(1);

[0073] Meanwhile, the second set of distance sensing elements 32 satisfies:

[0074] S(2) = LS(2) + RS(2);

[0075] Wherein, S(1) and S(2) are the final judgment results output by the first group of distance sensing elements 31 and the second group of distance sensing elements 32, respectively, and the judgment result can be abstractly defined as S(i). After receiving the judgment result, the execution unit 43 performs the preset control command action corresponding to the first group of distance sensing elements 31 (in this embodiment, turning on the lighting device 21) when S(1) = 0, that is, when at least one of the distance sensing elements is in the off state; when S(1) = 1, that is, when both distance sensing elements are in the closed state, it performs the opposite action to the above control command (in this embodiment, turning off the lighting device 21); similarly, when S(2) = 0, that is, when both distance sensing elements are in the off state, it performs the preset control action corresponding to the second group of distance sensing elements 32 (in this embodiment, stopping the operation of the cooling fan 22); when S(2) ≠ 0, that is, when as long as one distance sensing element is in the closed state, it performs the opposite action to the above control command (in this embodiment, driving the cooling fan 22 to work).

[0076] When the above process is extended to a total of n groups of distance sensing elements, the output judgment result S(i) can be further configured to satisfy:

[0077]

[0078] Wherein, Δx(i) represents the distance between the two distance sensing elements located at the farthest distance in the i-th group of distance sensing elements. Specifically, Δx(1) is defined as the distance between the first distance sensing element 311 and the second distance sensing element 312 in the first group of distance sensing elements 31, and Δx(2) is defined as the distance between the fourth distance sensing element 321 and the fifth sensing element 322 in the second group of distance sensing elements 32. X represents the preset distance. When Δx(i) is greater than the preset distance X, the Boolean operation relationship is configured as OR, and when Δx(i) is less than the preset distance X, the Boolean operation relationship is configured as AND.

[0079] Continuing, the distance sensing element is configured to be symmetrical about the center line of the crossbeam or vertical beam of the housing 200. In this embodiment, the preset spacing X can be configured to have a quantitative relationship with the spacing between the center line and the rotation axis.

[0080] In an embodiment where a third distance sensing element 33 is provided on the central line of symmetry, the control method further includes:

[0081] Step 61: Receive the signal from the first group of distance sensing elements 31, determine whether the first group of distance sensing elements 31 meets the triggering condition, and if so, execute the preset control command corresponding to the first group of sensing elements 31.

[0082] Step 62: Receive the signal from the second group of distance sensing elements 32, determine whether the second group of distance sensing elements 32 meets the triggering condition, and if so, execute the preset control command corresponding to the second group of distance sensing elements 32.

[0083] Step 63: When a signal is received from the third distance sensing element 33, execute the preset control command corresponding to the third distance sensing element.

[0084] That is, the third distance sensing element 33 is only provided on the central symmetry line, so there is no Boolean operation relationship. After receiving the signal, the communication unit 41 can forward the signal to the execution unit 43 through the judgment unit 42 and directly execute the corresponding control command.

[0085] In summary, the sensing device setting method provided by the present invention, by setting multiple sets of distance sensing elements at one of the door body 100 and the box body 200, and configuring the distance sensing elements to have special positional relationships and triggering logic, achieves the effect that opening the door from both sides can trigger the bidirectional symmetrical door opening device to execute the corresponding control commands respectively. At the same time, since at least two sets of distance sensing elements are configured to have different positional relationships relative to the center point, the technical effect of hierarchical triggering of control commands is further realized.
