The distance detection module is arranged to detect a distance between an object located in the sensing area and the non-contact key to generate a distance signal and transmit the distance signal to the signal processing module.
The signal processing module is arranged to generate a key control signal based on the distance signal.
The at least one key unit further each comprises a housing. The sensing area expansion module is fixed on an inner surface of a top portion of the housing, the distance detection module is arranged in the housing and opposite to the sensing area expansion module, and the signal processing module is arranged inside or outside the housing.
The sensing area expansion module comprises a lens, wherein the lens comprises a plane and a concave arc surface opposite to the plane, and the plane is fixed on an inner surface of the housing.

A distance signal is obtained via the distance detection module in the non-contact sensing key, where the distance signal is used to indicate a distance between an object located in a sensing area and the non-contact key.
A key control signal is generated based on the distance signal.
Throughout this specification the word "comprise", or variations such as "comprises" or "comprising", will be understood to imply the inclusion of a stated element, integer or step, or group of elements, integers or steps, but not the exclusion of any other element, integer or step, or group of elements, integers or steps.

FIG. 2 is a structural schematic diagram illustrating another non-contact key according to Embodiment one of the present invention;
FIG. 3 is a structural schematic diagram illustrating a non-contact key according to Embodiment two of the present invention; and

The present disclosure is described below in conjunction with the drawings and embodiments. Only parts not all of structures related to the present disclosure are illustrated in the drawings.
Embodiment one
This embodiment of the present invention provides a non-contact key. FIG.1 is a structural schematic diagram illustrating the non-contact key according to Embodiment one of the present invention. With reference to FIG. 1, the non-contact key includes at least one key unit. The at
2A least one key unit includes a sensing area expansion module 10, a distance detection module 20 and a signal processing module 30, and the distance detection module 20 is connected with the signal processing module 30.
In an embodiment, the sensing area expansion module 10 is configured to adjust a sensing area of the distance detection module 20.
The distance detection module 20 is configured to detect a distance between an object located within the sensing area and the non-contact key, to generate a distance signal, and to transmit the distance signal to the signal processing module 30.
The signal processing module 30 is configured to generate a key control signal based on the distance signal.
In an embodiment, the non-contact key includes at least one key unit. The at least one key unit includes the sensing area expansion module 10, the distance detection module 20 and the signal processing module 30. The distance detection module 20 is connected with the signal processing module 30. The sensing area expansion module 10 is configured to adjust the sensing area of the distance detection module 20, and the distance detection module 20 is configured to detect the distance from the object located within the sensing area to the non-contact key. The sensing area is a spatial range where the distance detection module 20 in the key unit can detect the object. For example, when the sensing area expansion module 10 enlarges the sensing area of the distance detection module 20, with reference to FIG. 1, the !0 sensing area expansion module 10 being capable of increasing the sensing area of the distance detection module 20 is reflected in that a sensing area b when the sensing area expansion module 10 is not set is enlarged to a sensing area a after the sensing area expansion module 10 is set, that is, a size of a light area is adjusted, thereby adjusting the sensing area. The sensing area expansion module 10 may also be configured to narrow the sensing area of the distance detection module 20, which is set according to actual conditions. When detecting an object located within the sensing area, the distance detection module 20 is further configured to generate the distance signal based on the distance from the object within the sensing area to the non-contact key. The distance detection module 20 is in communication connection with the signal processing module 30. The distance detection module 20 can transmit the distance signal to the signal processing module 30, and the signal processing module 30 generates the key control signal based on the distance signal to control the key. The distance detection module 20 and the signal processing module 30 may be connected in a wired manner or in a wireless manner, which is not limited herein. The arrangement of the sensing area expansion module 10 in this embodiment of the present invention realizes adjustment of the sensing area of the key. In addition, the non-contact key realized by proximity capacitive sensing requires that a proximity distance of a detected object is relatively less, making this type of keys not easy to control, and more likely to be misoperated by environmental interference. While, the distance detection module 20 provided by this embodiment of the present application can realize long-distance monitoring of the object, enlarging the sensing area of the key, enhancing anti-interference ability of the key, and improving using efficiency of the key.
In an embodiment, the distance detection module 20 includes a time-of-flight sensor. The time-of-flight sensor measures time required for an object to travel through a medium, that is, the time is usually a measure of time elapsed between the moment when the time-of-flight sensor emits a wave pulse and the moment when the wave pulse after reflected by the object returns to the time-of-flight sensor. A distance between the time-of-flight sensor and the object can be measured by converting the time into distance. The time-of-flight sensor can accurately detect objects with 3 mm resolution in a range from 0 mm to 100 mm or more. The distance detection module 20 meets the requirements of enlarging the sensing area of the key, enhancing the anti-interference ability of the key, and improving the using efficiency of the key.
In an embodiment, with reference to FIG. 1, the at least one key unit further includes a housing 40, the sensing area expansion module 10 is fixed on an inner surface of a top portion of the housing 40, the distance detection module 20 is arranged in the housing 40 and opposite to the sensing area expansion module 10, and the signal processing module 30 is arranged in the housing 40.
In an embodiment, FIG. 2 is a structural schematic diagram illustrating another non-contact key according to Embodiment one of the present invention. With reference to FIG. 2, the key unit further includes a housing 40, the sensing area expansion module 10 is fixed on the inner surface of the top portion of the housing 40, the distance detection module 20 is arranged in the housing 40 and opposite to the sensing area expansion module 10, and the signal processing module 30 is arranged outside the housing 40.
In an embodiment, each key unit further includes the housing 40 to form a package structure of a key. The sensing area expansion module 10 in the key unit is fixed on the inner surface of the top portion of the housing 40, and the distance detection module 20 is arranged in the housing 40 and opposite to the sensing area expansion module 10. The signal processing module 30 may be arranged in a cavity of the housing 40, or the signal processing module 30 may be arranged outside the housing 40 and processes the distance signal collected by the distance detection module 20. In an embodiment, each of the at least one key unit is in one-to-one correspondence with a respective signal processing module 30.
In an embodiment, with reference to FIG. 1, the sensing area expansion module 10 includes a lens 11. The lens includes a plane and a concave arc surface opposite to the plane. The plane is fixed on the inner surface of the housing 40. A focal length of the lens 11 is adjusted by adjusting a material and / or a radian radius of the lens 11 so as to adjust the size of the light area. The less the focal length of the lens 11 is, the greater a divergence angle of the light through the lens 11 is, thereby enlarging a range of the sensing area, that is, the lens 11 is a concave lens. In another solution provided by the present embodiment, the focal length of the lens 11 is adjusted by adjusting the material and / or the radian radius of the lens 11 so as to reduce the size of the light area. The lens 11 includes a plane and a convex arc surface that are oppositely arranged. The plane is fixed on the inner surface of the housing 40, that is, the lens 11is aconvexlens.
In an embodiment, with reference to FIG. 1, the at least one key unit further includes a key state feedback module 50. The key state feedback module 50 is arranged on an outer side of the housing 40 and configured to feed back a key state signal. The key state signal includes at least one of a no-object-approaching indication signal, an object-approaching indication signal, an !0 object-entering-the-sensing-area indication signal, and a sensing-success indication signal. The signal processing module 30 is connected with the key state feedback module 50, and the signal processing module 30 is further configured to output a control signal to the key state feedback module 50 based on the distance signal and a combination of a preset sensing distance and preset sensing time. In an embodiment, the key state feedback module 50 includes a display device and / or a voice device to visually and / or acoustically feed back a sensing state of the key unit to the object.
Exemplarily, the key state feedback module 50 is an indicator light. When the key unit does not sense the object for a long time, the indicator light indicates, in a form of a breathing lamp, an indication signal that no object approaches, and the key unit is in a standby state. When the distance detection module 20 of the key unit detects that an object approaches, the indicator light displays, in a dimply lighting form, an indication signal that the object approaches. When the distance detection module 20 of the key unit detects that an object enters the sensing area, the indicator light indicates, in a quickly flashing form, an indication signal that the object enters the sensing area. When the distance detection module 20 of the key unit confirms success of sensing, the indicator indicates, in a constant lighting form, an indication signal that the sensing is successful.
In an embodiment, a sensing distance of each key unit may be arranged separately.
In an embodiment, the sensing distance of the each key unit may be designed separately. After collecting the distance signal of the object, the distance detection module 20 transmits the distance signal of the object to the signal processing module 30. The signal processing module 30 compares a distance corresponding to the received distance signal of the object with the preset sensing distance. If the preset sensing distance is greater than the distance corresponding to the received distance signal of the object, it determines that the sensing of the key unit is successful.
In another solution provided by the present embodiment, the sensing distance of the key unit is adjustable, and parameters of a product may be fixed after leaving a factory. The sensing distance of the object may be designed separately by setting different preset sensing distances via the signal processing module 30. The sensing distance of the key may be increased in an occasion where a key interval is relatively large, and the sensing distance of the key may be reduced in an occasion where the key interval is relatively small. The sensing distance of the key may be increased in an occasion where the elderly and children operate more, and the sensing distance may be reduced in crowded occasions such as office buildings. The sensing !0 distance may also be parameterized. After the product is put into service, users can make adjustments according to use situations. The design is humanized and can provide users with more effective services.
In an embodiment, sensing time of the each key unit may be arranged separately. The signal processing module 30 sets different preset sensing time to realize separate design of the sensing time for the each key unit.
In another solution provided by the present embodiment, the sensing time of the key unit is adjustable, and parameters of the product may be fixed after leaving the factory. In an occasion where a required efficiency is relatively high, a threshold value of the sensing time, that is, the preset sensing time, may be designed to be slightly less, and in an occasion where space environment is harsh and easy to be interfered, the threshold value of the sensing time, that is, the preset sensing time, may be designed to be slightly greater. The sensing time may also be parameterized. After the product is put into service, users can make adjustments according to use situations. The design is humanized and can provide the users with more effective services.
In an embodiment, the key unit may be designed to reduce sensing time of this confirmation when it is detected that a distance corresponding to a distance signal of an object is much less than a set value of the preset sensing distance. For example, in a case where the set value of the preset sensing distance is 10 mm and the set value of the preset sensing time is 700 ms, if it is detected that the distance of the object is 5 mm, the sensing time exceeding 500 ms can be considered as a valid signal without reaching 700 ms. This embodiment of the present invention improves environmental adaptability and anti-interference ability of the key unit. In addition, the design is humanized and can provide the users with more effective services.
This embodiment of the present invention provides a non-contact key that includes at least one key unit. The at least one key unit includes a sensing area expansion module, a distance detection module and a signal processing module, and the distance detection module is connected with the signal processing module. The sensing area expansion module is configured to enlarge a sensing area of the distance detection module. The distance detection module is configured to detect a distance from an object located within the sensing area to the non-contact key, to generate a distance signal, and to transmit the distance signal to the signal processing module. The signal processing module is configured to generate a key control signal based on the distance signal. The technical solution provided by this embodiment of the present invention !0 enhances the anti-interference ability of the key, improves the using efficiency of the key, and enlarges the sensing area of the key by arranging the sensing area expansion module. The separately designed sensing distance and / or sensing time improves the environmental adaptability and anti-interference ability of the key unit. In addition, the design is humanized and can provide the users with more effective services.

The key control method can be performed by the signal processing module. FIG. 4 is a flowchart illustrating the key control method according to Embodiment three of the present invention. With reference to FIG. 4, the key control method includes steps S10 and S20.
In step S10, a distance signal is obtained via the distance detection module in the non-contact key, where the distance signal is used to indicate a distance from an object located within a sensing area to the non-contact key.
In an embodiment, the non-contact key includes at least one key unit. The key unit includes a sensing area expansion module, a distance detection module and a signal processing module, and the distance detection module is connected with the signal processing module. The sensing area expansion module is configured to adjust the sensing area of the distance detection module. The distance detection module is configured to detect the distance from the object located within the sensing area to the non-contact key and generate the distance signal. The distance signal is used to indicate the distance from the object located within the sensing area to the non-contact key.
In step S20, a key control signal is generated based on the distance signal.
In an embodiment, the distance detection module is connected with the signal processing module. The distance detection module detects the distance from the object located within the sensing area to the non-contact key, generates the distance signal, and transmits the distance signal to the signal processing module. Then the signal processing module generates the key control signal based on the distance signal.
In an embodiment, the key control signal being generated based on the distance signal including the following content.
In a case where it is determined that a distance corresponding to the distance signal is less than or equal to a preset distance, a first control signal is generated when it is determined that the sensing time of the object reaches the preset time, so as to instruct a target device to perform an action corresponding to the first control signal, where the preset distance is less than a preset sensing distance, and the preset time is less than preset sensing time.
In a case where it is determined that the distance corresponding to the distance signal is less than or equal to the preset sensing distance and greater than the preset distance, the first control signal is generated when it is determined that the sensing time of the object reaches the preset sensing time.
In a case where it is determined that the distance corresponding to the distance signal is greater than the preset sensing distance, a second control signal is generated, so as to instruct the target !0 device to maintain an original action.
Exemplarily, a set value of the preset sensing distance is 10 mm, the set value of the preset sensing time is 700 ms, and the preset distance is 5 mm. If it is detected that the distance corresponding to the distance signal of the object is 3 mm, that is, the distance corresponding to the distance signal is less than or equal to the preset distance, the signal processing module can generate the first control signal when it is determined that the sensing time of the object reaches the preset time of 500 ms, so as to instruct the target device to perform a corresponding action without reaching the preset sensing time of 700 ms. If it is detected that the distance corresponding to the distance signal of the object is 8 mm, that is, the distance corresponding to the distance signal is less than or equal to the preset sensing distance and greater than the preset distance, the signal processing module can generate the first control signal only when the sensing time of the object reaches the preset sensing time of 700 ms, so as to instruct the target device to perform the corresponding action. If it is detected that the distance corresponding to the distance signal of the object is 12 mm, that is, when the distance corresponding to the distance signal of the object is greater than the preset sensing distance, the signal processing module generates the second control signal, so as to instruct the target device to maintain the original action.
The technical solution provided by this embodiment of the present invention can reduce sensing time of this confirmation when it is detected that the distance corresponding to the distance signal of the object is much less than the set value of the preset sensing distance, thereby improving environmental adaptability and anti-interference ability of the key. In addition, the design is humanized and can provide the users with more effective services.
