All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
At present, the password keyboard is generally a key type password keyboard, and belongs to a contact password keyboard. Specifically, the user is required to touch the face of the keypad and press the keys on the face of the keypad, and the key sensors below the face of the keypad convert this pressing operation into an electrical signal, thereby determining which key the user presses. However, the inventors have found that contacting a keypad, such as a push-button keypad, necessarily causes the user to contact the face of the keypad. If a user is a pathogen carrier, part of pathogens are likely to be left on the surface of the password keyboard in the contact process of the user and the surface of the password keyboard; other subsequent users are likely to take away pathogens left on the surface of the password keyboard during contact with the surface of the password keyboard; that is, the touch-tone keypad becomes a transmission medium for pathogens.
In order to solve the problem, in the embodiment of the application, a plurality of groups of correlation type photoelectric sensors which are arranged in a net shape are arranged in a preset range on the periphery above the surface of a password keyboard in advance, and if the fact that the emission light beams of target correlation type photoelectric sensors in the plurality of groups of correlation type photoelectric sensors are blocked by a target object is detected, counting of the blocking time corresponding to the target correlation type photoelectric sensors is started; when the blocking time is more than or equal to the preset time, determining a target key corresponding to a target object from the surface of the password keyboard; and generating a target key signal corresponding to the target key. Therefore, a plurality of groups of correlation type photoelectric sensors which are arranged in a net shape are arranged in a preset range above the surface of the password keyboard, and then the non-contact password keyboard can be obtained; detecting that the emission light beam of a target correlation type photoelectric sensor in a plurality of groups of correlation type photoelectric sensors is blocked for a period of time, and indicating that keys corresponding to the suspended positions of objects on the surface of the password keyboard are target keys so as to realize non-contact keys; based on this, the phenomenon that the password keyboard becomes a pathogen transmission medium is avoided.
For example, one of the scenarios in the embodiment of the present application may be applied to the scenario shown in fig. 1, where the scenario includes the contactless cryptographic keyboard 101, the processor 102, and the terminal device 103, the contactless cryptographic keyboard 101 and the processor 102 are installed on the terminal device 103, and multiple sets of correlation type photosensors disposed in a mesh shape are disposed in a preset range above and around a surface of the cryptographic keyboard in the contactless cryptographic keyboard 101. When a finger of a user hovers above a surface of a password keyboard in the contactless password keyboard 101, if the processor 102 adopts the implementation manner of the contactless password keyboard processing method provided by the embodiment of the present application, a target key signal corresponding to a target key is generated, and the processor 102 sends the target key signal to the terminal device 103.
First, in the application scenario described above, although the actions of the embodiments provided in the embodiments of the present application are described as being performed by the processor 102; however, the embodiments of the present application are not limited in terms of executing subjects as long as the actions disclosed in the embodiments provided by the embodiments of the present application are executed.
Next, the above scenario is only one example of the scenario provided in the embodiment of the present application, and the embodiment of the present application is not limited to this scenario.
The following describes in detail a specific implementation manner of the method for processing a contactless password keyboard and a related apparatus in the embodiments of the present application by using embodiments with reference to the accompanying drawings.
Exemplary method
Referring to fig. 2, a flowchart of a method for processing a contactless cryptographic keyboard in an embodiment of the present application is shown. In this embodiment, a plurality of sets of correlation type photosensors disposed in a mesh shape are preset in a preset range above the surface of the keypad, and the method may include the following steps:
step 201: and if detecting that the emission light beam of the target correlation type photoelectric sensor in the plurality of sets of correlation type photoelectric sensors is blocked by the target object, starting to count the blocking time corresponding to the target correlation type photoelectric sensor.
Because the user is bound to contact with the surface of the password keyboard due to the contact of the key-type password keyboard and the like with the password keyboard, if a certain user is a pathogen carrier, part of pathogens are likely to be left on the surface of the password keyboard in the contact process of the certain user with the surface of the password keyboard; other subsequent users are likely to take away pathogens left on the surface of the password keyboard during contact with the surface of the password keyboard; that is, the touch-tone keypad becomes a transmission medium for pathogens. Therefore, in the embodiment of the application, multiple groups of oppositely-emitting photoelectric sensors which are arranged in a net shape are arranged in a preset range above and around the surface of the password keyboard in advance, and the multiple groups of oppositely-emitting photoelectric sensors which are arranged in the net shape can distinguish each key on the surface of the password keyboard, so that whether the emission light beams of the multiple groups of oppositely-emitting photoelectric sensors are blocked by an object or not is detected subsequently, and the non-contact keys of the non-contact password keyboard are realized; and a plurality of groups of correlation type photoelectric sensors which are arranged in a net shape are arranged in a preset range above the surface of the password keyboard, so that the contact between the body of a user and the surface of the password keyboard is avoided, and the non-contact password keyboard can be obtained.
As an example, as shown in fig. 3, a top view schematic diagram of a contactless cryptographic keyboard, sets multiple sets of correlation type photosensors arranged in a horizontal and vertical intersecting manner in a preset range around a cryptographic keyboard surface, and because 16 keys, 4 × 4, are provided on the cryptographic keyboard surface, 8 sets of correlation type photosensors arranged in a horizontal and vertical intersecting manner are provided in the preset range around the cryptographic keyboard surface, specifically, a0 and a1, B0 and B1, C1 and C1, D1 and D1, W1 and W1, X1 and X1, Y1 and Y1, and Z1, where a1, B1, C1, D1, W1, X1, Y1, Z1 are transmitters of correlation type photosensors, and a1, B1, C1, D1, W1, Y1, and Z1 are receivers of correlation type photosensors.
In the embodiment of the application, in order to avoid that the distance between the plane formed by the plurality of groups of correlation type photoelectric sensors and the surface of the password keyboard is short, and a target object is easy to contact with the surface of the password keyboard, a certain distance needs to be kept between the plane formed by the correlation type photoelectric sensors and the surface of the password keyboard. Then, a distance lower limit value is preset as a preset distance, and when the distance between the plane formed by the plurality of groups of correlation type photoelectric sensors and the surface of the password keyboard is larger than or equal to the preset distance, the target object can be prevented from contacting the surface of the password keyboard. Therefore, in an optional implementation manner of the embodiment of the present application, a distance between a plane formed by the multiple sets of correlation type photoelectric sensors and the surface of the keypad is greater than or equal to a preset distance.
Based on the above description, as long as the distance between the plane formed by the plurality of groups of correlation type photoelectric sensors and the surface of the code keyboard is greater than or equal to the preset distance, the plane formed by the plurality of groups of correlation type photoelectric sensors can be parallel to the surface of the code keyboard, and can also form a certain included angle with the surface of the code keyboard, that is, a suitable included angle range is preset as the preset included angle range, and the included angle between the plane formed by the plurality of groups of correlation type photoelectric sensors and the surface of the code keyboard needs to be within the preset included angle range. Therefore, in an optional implementation manner of the embodiment of the present application, the plane that the multiple sets of correlation type photoelectric sensors constitute with the code keyboard disk surface is parallel, or the plane that the multiple sets of correlation type photoelectric sensors constitute with the included angle of the code keyboard disk surface conforms to a preset included angle range.
As an example, based on fig. 3, as shown in fig. 4, which is a schematic longitudinal section of a contactless cryptographic keyboard, 8 groups of radial photoelectric sensors are arranged in parallel with the surface of the cryptographic keyboard, 8 groups of radial photoelectric sensors are arranged at a distance d from the surface of the cryptographic keyboard, and d is greater than a preset distance d0。
It should be noted that, in a normal situation, when a light beam emitted by the opposite-emission type photoelectric sensor is not blocked by an object, an output signal of the opposite-emission type photoelectric sensor is unchanged; when an object hovers above the surface of the password keyboard, the emitted light beams of a certain group or a certain group of the multiple groups of correlation type photoelectric sensors can be blocked, namely the emitted light beams of a target correlation type photoelectric sensor in the multiple groups of correlation type photoelectric sensors are blocked, and under the condition, the output signals of the target correlation type photoelectric sensor are changed. That is, when a change in the output signal of the target opposite-type photosensor of the plurality of sets of opposite-type photosensors is detected, it indicates that the emission light beam of the target opposite-type photosensor of the plurality of sets of opposite-type photosensors is blocked by an object, which is referred to as a target object. Therefore, in an alternative implementation manner of the embodiment of the present application, the emitted light beam of the target correlation type photosensor is blocked by the target object, specifically, the output signal of the target correlation type photosensor is changed.
Wherein, the common target object can be, for example, a user finger; therefore, in an alternative implementation of this embodiment of the present application, the target object includes a finger of a user. Of course, the target object is not limited in the embodiments of the present application, and the target object may be an object other than a finger.
As an example, based on fig. 3, as shown in fig. 5, when the emission beams of the multiple sets of correlation type photosensors are not blocked by the target object, the output signals of the multiple sets of correlation type photosensors are not changed, which indicates that no target object hovers above the surface of the keypad.
As an example, based on fig. 3, as shown in fig. 6, the schematic diagram of the emission beams of the target correlation type photo sensor in the multi-group correlation type photo sensor are blocked by the target object, and the emission beams of B0 and B1, Y0 and Y1 in the 8-group correlation type photo sensor are blocked by the target object, which indicates that the target object hovers over the surface of the password keyboard at the time.
In the embodiment of the application, because the target object is hovered above the surface of the password keyboard, the time when the emission beam of the target correlation type photoelectric sensor is blocked by the target object is related to whether a user presses keys without contact; therefore, at this time, it is necessary to start counting the blocking time corresponding to the target correlation type photosensor.
Step 202: and when the blocking time is more than or equal to the preset time, determining a target key corresponding to the target object from the surface of the password keyboard.
In the embodiment of the application, only when the emission light beam of the target opposite-emission type photoelectric sensor is blocked by the target object for a period of time, that is, the target object hovers above the surface of the password keyboard for a period of time, it can be indicated that the target key corresponding to the target object is the key that the user wants to have no contact with the key. Therefore, a time threshold is preset as the preset time, only the blocking time corresponding to the target correlation type photoelectric sensor obtained through statistics is larger than or equal to the preset time, and the target key corresponding to the target object is determined to be the key which the user wants to have no contact with the key on the surface of the password keyboard.
Specifically, since each key on the surface of the keypad can be distinguished by a plurality of sets of correlation type photosensors deployed in a mesh shape, the target key corresponding to the target object may be determined, for example, by the deployment position of the target correlation type photosensors. Therefore, in an optional implementation manner of this embodiment of the present application, the step 202 may include, for example, the steps of: and analyzing the deployment position of the target correlation type photoelectric sensor, and determining the target key corresponding to the target object from the surface of the password keyboard.
As an example, on the basis of fig. 6, the deployment positions of B0 and B1, Y0 and Y1 in 8-group radial type photoelectric sensors are analyzed, and a target key "8" corresponding to a target object is determined from the surface of a 4 × 4-16-key code keypad.
Step 203: and generating a target key signal corresponding to the target key.
In this embodiment of the application, after the target key corresponding to the target object is determined in step 202, since the target key corresponding to the target object is a key that the user wishes to use as a contactless key, it is necessary to generate a key signal corresponding to the target key as the target key signal based on the target key.
In addition, in this embodiment of the application, after the target key signal corresponding to the target key is generated in step 203, it indicates that the user implements a contactless key for the target key corresponding to the target key, and then a successful contactless key for the target key may be prompted. Therefore, in an optional implementation manner of this embodiment of the present application, after the step 203, for example, a step 204 may further be included: and prompting the target key to be successfully pressed in a non-contact manner.
Through various implementation manners provided by this embodiment, multiple sets of correlation photoelectric sensors disposed in a mesh shape are set in a preset range above the surface of the password keyboard in advance, and if it is detected that an emission beam of a target correlation photoelectric sensor in the multiple sets of correlation photoelectric sensors is blocked by a target object, counting blocking time corresponding to the target correlation photoelectric sensor is started; when the blocking time is more than or equal to the preset time, determining a target key corresponding to a target object from the surface of the password keyboard; and generating a target key signal corresponding to the target key. Therefore, a plurality of groups of correlation type photoelectric sensors which are arranged in a net shape are arranged in a preset range above the surface of the password keyboard, and then the non-contact password keyboard can be obtained; detecting that the emission light beam of a target correlation type photoelectric sensor in a plurality of groups of correlation type photoelectric sensors is blocked for a period of time, and indicating that keys corresponding to the suspended positions of objects on the surface of the password keyboard are target keys so as to realize non-contact keys; based on this, the phenomenon that the password keyboard becomes a pathogen transmission medium is avoided.
