Referring to fig. 3, the present application is applicable to a capacitive touch device 10 having a magnetic attraction function, and a capacitive touch key 320 disposed on a surface of the device where a magnetic attraction contact 310 is located. When the capacitive touch device 10 is not connected with the external device 20 in a sucking way, the capacitive touch device 10 itself realizes function control, and when the capacitive touch device is connected with the external device 20 through the magnetic contact 310, the external device 20 bears the function control task of the sucked capacitive touch device 10, namely the function control task is executed by the external device.
Referring to fig. 1, in one implementation, the present application provides a method for shielding a touch key, which is applied to a capacitive touch device connected to an external device through a magnetic contact; the method comprises the following steps:
step S110: detecting whether the capacitance value corresponding to the capacitive touch key is increased to a preset capacitance value, and if not, shielding the touch key function of the capacitive touch device.
In the process that the external equipment and the capacitive touch equipment are in suction connection through the magnetic contact, a touch key of the capacitive touch equipment is touched by non-finger foreign objects such as a plane of the external equipment, and the quantity of charge transfer caused by two actions of touching by a finger is different, so that the capacitance value variation corresponding to the touch key is different. The increment of the corresponding capacitance value when a non-finger foreign object such as a plane of the external device touches the touch key is smaller than that when a finger touches the touch key. Therefore, a trigger response threshold, namely a preset capacitance value, can be set, and the unintentional operation is filtered by detecting the capacitance value variation corresponding to the touch key, if the capacitance value corresponding to the touch key is increased to the preset capacitance value, the touch of the finger of the user can be responded, and if the corresponding capacitance value does not reach the preset capacitance value, the touch of the finger of the non-user such as a plane of the external equipment can be shielded. Therefore, the influence of incorrect response on the normal operation of the equipment caused by the suction connection with the external equipment can be prevented.
The embodiment of the application has higher recognition sensitivity, can effectively and rapidly filter out misoperation on the capacitive touch key, and ensures that the capacitive touch device can respond to the instruction of the touch key by mistake in the process of sucking the capacitive touch device and the external device.
Step S120: if yes, detecting whether the touch device is connected with the external device or not through the magnetic attraction contact of the capacitive touch device, and if yes, shielding the touch key function of the capacitive touch device.
In order to prevent misjudgment, after the capacitance value corresponding to the capacitive touch key is increased to a preset capacitance value, whether the capacitive touch device is connected with the external device or not can be detected through the magnetic contact of the capacitive touch device, so that even if the capacitive touch device and the external device are not completely attached, the attached capacitive touch device can timely shield the touch key function, the situation of false touch is effectively broken, and if the connection with the external device is not detected, a key instruction corresponding to the capacitive touch key is responded. The method comprises the steps of detecting whether a mode of connecting with external equipment exists through a magnetic attraction contact of the capacitive touch equipment, if so, detecting whether the voltage of an IO control port connected with the corresponding magnetic attraction contact changes, namely, whether a preset voltage value is reached, if so, indicating that the external equipment is connected, or detecting whether the IO control port connected with the corresponding magnetic attraction contact receives a handshake instruction sent by the external equipment, and if so, indicating that the external equipment is connected.
The shielding method of the touch key is applied to the capacitive touch device connected with the external device through the magnetic contact, and is used for detecting whether the capacitance value corresponding to the capacitive touch key is increased to a preset capacitance value or not in the adsorption connection process of the external device, and shielding the key function of the capacitive touch device if the capacitance value is not increased to the preset capacitance value. If yes, detecting whether the touch device is connected with an external device or not through a magnetic contact of the capacitive touch device, and if yes, shielding the touch key function. The embodiment of the application can combine multiple judging factors to prevent misjudgment, so that when the capacitive touch device is in contact connection with the external device through the magnetic contact, misoperation caused by external devices and other foreign objects is filtered, and meanwhile, the situation that after connection, the capacitive touch device is prevented from being influenced by mistriggering of a touch key caused by adsorption and lamination of the external device can be ensured. The application can meet the operation and use requirements of the capacitive touch equipment connected with the external equipment through the magnetic contact, so that stable information interaction transmission with strong anti-interference capability can be realized after the capacitive touch equipment and the external equipment are connected through the magnetic contact.
In a specific embodiment, the touch key function of the capacitive touch device is masked, and then comprises:
and receiving a user key instruction obtained by an external device connected with the magnetic contact.
According to the shielding method of the touch key, after the touch key function of the adsorbed capacitive touch device is shielded, the external device sends a user key instruction to the capacitive touch device, namely, the function of interaction with a user is transferred to the external device. The application is convenient for the external device to adsorb the capacitive touch device through the magnetic contact, thereby improving the stability and the effectiveness of the communication connection of the external device and the capacitive touch device, preventing the signal crosstalk of the touch key and ensuring the normal operation of the device.
In a specific embodiment, after "detecting whether the capacitance value corresponding to the capacitive touch key is increased to the preset capacitance value", the method further includes:
if the capacitance value corresponding to the capacitive touch key is increased to the preset capacitance value, detecting whether the capacitance values corresponding to the capacitive touch keys are increased at the same time, and if so, shielding the touch key function.
If not, executing the step of detecting whether the external equipment is connected or not.
In the process that the external device and the capacitive touch device are attracted through the magnetic attraction contact, namely when the external device is pressed on the capacitive touch device, the situation that the capacitance values corresponding to the capacitive touch keys are increased at the same time exists, namely the situation that the touch keys are touched at the same time is indicated. In normal operation, there is no action that a plurality of keys are pressed down simultaneously, so that even if the capacitance value corresponding to the detected capacitive touch key is increased to a preset capacitance value, in order to eliminate external interference factors and prevent erroneous judgment, whether the capacitance value corresponding to the plurality of capacitive touch keys is increased simultaneously can be detected, if yes, no response is made to shield the touch key function, if not, whether the connection with an external device is detected through the magnetic attraction contact of the capacitive touch device, if yes, the touch key function is shielded, otherwise, a key instruction corresponding to the capacitive touch key can be responded.
The embodiment of the application can further reduce the false triggering condition of the touch key on the adsorbed capacitive touch device caused by the covering action when the external device is connected with the capacitive touch device through the magnetic contact, and can improve the detection precision.
In a specific embodiment, the "detecting whether there are a plurality of capacitive touch keys corresponding to increased capacitance values" further includes:
if the increase of the capacitance values corresponding to the capacitive touch keys is not detected, whether the capacitance values corresponding to the capacitive touch keys are kept unchanged is detected within preset time, and if yes, the touch key function is shielded.
If not, executing the step of detecting whether the external equipment is connected or not.
The embodiment of the application only responds to the loosening transient state in the action of pressing the capacitive touch key, and the capacitive touch key is restored to the original value in a short time after the capacitance value corresponding to the capacitive touch key is increased. The external device is pressed down and not loosened after the capacitive touch device is adsorbed by the magnetic contact, and the capacitance value corresponding to the capacitive touch key is kept unchanged. Therefore, in the embodiment of the application, if the increase of the capacitance values corresponding to the plurality of touch keys is not detected, in order to further eliminate the misjudgment caused by external interference factors, whether the capacitance values corresponding to the capacitive touch keys are kept unchanged can be detected within a preset time, and if so, no response is made to shield the touch key function. If not, detecting whether the touch key is connected with the external device or not through the magnetic attraction contact of the capacitive touch device, if so, shielding the touch key function, and if not, responding to a key instruction of the corresponding capacitive touch key. Wherein the preset time is preferably 4s-6s.
The embodiment of the application can further reduce the false triggering condition of the touch key on the adsorbed capacitive touch device caused by the covering action when the external device is connected with the capacitive touch device through the magnetic contact, and can improve the detection precision and has stronger anti-interference capability.
Referring to fig. 3, in a specific embodiment, an infrared sensor 330 is disposed in the capacitive touch device 10, and the infrared sensor 330 is located beside the magnetic attraction contact 310 and spaced apart from the capacitive touch key area 340 by a predetermined distance;
the method further comprises the steps of:
when the infrared induction intensity sensed by the infrared sensor is detected to be greater than or equal to a preset intensity threshold value within a preset detection distance, determining that the function of the external equipment for approaching and shielding the touch key exists; otherwise, executing the step of detecting the capacitance value corresponding to the capacitive touch key.
The number of the infrared sensors 330 is at least one. The infrared sensor 330 is built in the capacitive touch device 10, and when an object is arranged on the surface of the capacitive touch device and the touch device is closer to the surface, the sensed infrared sensing intensity is stronger, so that the capacitive touch device 10 can be triggered to shield a touch key function when an external object approaches to within a preset detection distance by reasonably setting a threshold value. Wherein the preset detection distance is preferably 4cm-6cm. When the capacitive touch device 10 is connected to the external device through the magnetic contact 310, the capacitive touch device 10 is gradually close to the external device 20, and the infrared induction intensity is detected to be greater than or equal to the preset intensity threshold within the preset detection distance, it is determined that the external device 20 is close to and shields the touch key function. For example, when the infrared sensing intensity is greater than or equal to the preset threshold, the flag position 1 indicates that the external device 20 is determined to be close to shield the touch key function, and the subsequent detection step of the capacitance value corresponding to the capacitive touch key is not needed, otherwise, the subsequent relevant detection step is entered, so that misjudgment caused by external factors is prevented. The infrared sensor 330 is located beside the magnetic contact 310 and is separated from the capacitive touch key area 340 by a preset distance, so as to avoid the normal operation range of the human hand, or the infrared induction intensity caused by the operation of the human hand in the touch key area 340 is insufficient to reach the preset intensity threshold, so as to realize effective distinction.
The embodiment of the application has the advantages that the detection mode is simple and easy to realize, the program redundancy can be reduced, and whether the external equipment 20 is to be magnetically attracted to the capacitive touch equipment 10 or not can be effectively and rapidly judged, so that the touch key function is shielded in time, the additional detection process is omitted, and the detection sensitivity is improved. And simultaneously, when the external device 20 is sucked with the sucked capacitive touch device 10 through the contact, false triggering response is prevented.
In order to further explain the shielding method of the touch key according to the embodiment of the present application, as shown in fig. 2, when the capacitive touch key according to the embodiment of the present application is connected to an external device through a magnetic contact, in order to prevent the capacitive touch key on the capacitive touch device from being affected by incorrect response after being pressed by the external device, the method may be performed as follows:
step S2: and detecting whether the infrared induction intensity sensed by the infrared sensor is greater than or equal to a preset intensity threshold within a preset detection distance, if not, entering a step S4, and if so, entering a step S14.
Step S4: detecting whether the capacitance value corresponding to the capacitive touch key is increased to a preset capacitance value, if not, entering step S14, and if yes, entering step S6.
Step S6: and detecting whether the capacitance values corresponding to the capacitive touch keys are increased at the same time, if so, entering a step S14, and if not, entering a step S8.
Step S8: and detecting whether the capacitance value corresponding to the capacitive touch key is kept unchanged within a preset time, if so, entering a step S14, otherwise, entering a step S10.
Step S10: and detecting whether the capacitive touch device is connected with external equipment or not through the magnetic attraction contact of the capacitive touch device, if so, entering a step S14, and if not, entering a step S12.
Step S12: and executing the key instruction.
Step S14: shielding the touch key function.
According to the shielding method of the touch key, disclosed by the embodiment of the application, a plurality of judgment factors can be combined to prevent misjudgment, so that when the capacitive touch device is in contact connection with the external device through the magnetic contact, misoperation caused by external devices and other external objects is filtered, and meanwhile, the situation that after connection, the capacitive touch device cannot be influenced by mistriggering of the touch key caused by adsorption and lamination of the external device can be ensured. The application can meet the operation and use requirements of the capacitive touch equipment connected with the external equipment through the magnetic contact, so that stable information interaction transmission with strong anti-interference capability can be realized after the capacitive touch equipment and the external equipment are connected through the magnetic contact.
