Referring to fig. 3, the present invention is suitable for a capacitive touch device 10 having a magnetic attraction function and a capacitive touch key 320 disposed on a surface of the device where the magnetic attraction contact 310 is located. When the capacitive touch device 10 is not attracted to the external device 20, the capacitive touch device 10 itself implements function control, and after the capacitive touch device is connected to the external device 20 through the magnetic attraction contact 310, the external device 20 undertakes a function control task of the attracted capacitive touch device 10, that is, the function control task is executed by the external device.
Referring to fig. 1, in one embodiment, the present invention provides a shielding method for 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: and 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 equipment.
In the process that the external equipment and the capacitive touch equipment are attracted through the magnetic attraction contact, the touch key of the capacitive touch equipment is touched by non-finger foreign objects such as the plane of the external equipment, and the quantity of electric charge transferred is different from that caused by two actions of being touched by a finger, so that the capacitance value variation corresponding to the touch key is different. When a non-finger foreign object such as a plane of the external device touches the touch key, the corresponding capacitance increment is smaller than that when a finger touches the touch key. Therefore, a trigger response threshold value, namely a preset capacitance value, can be set, the non-directional operation can be 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 can be responded by the finger of the user, and if the corresponding capacitance value does not reach the preset capacitance value, the touch can be shielded by the touch of the non-user fingers such as the plane of the external equipment. Therefore, the influence of false response on the normal work of the equipment can be prevented when the external equipment is sucked and connected.
The embodiment of the invention has higher identification sensitivity, can effectively and quickly filter the misoperation of the capacitive touch key, and ensures that the instruction of the touch key is responded by mistake in the suction connection process of the capacitive touch equipment and the external equipment.
Step S120: and if so, detecting whether the connection with the external equipment exists or not through a magnetic attraction contact of the capacitive touch equipment, and if so, shielding the touch key function of the capacitive touch equipment.
In order to prevent misjudgment, after the capacitance value corresponding to the capacitive touch key is increased to the preset capacitance value, whether the capacitive touch key is connected with the external equipment or not can be detected through the magnetic attraction contact of the capacitive touch equipment, so that even if the capacitive touch key and the external equipment are not completely attached to each other, the adsorbed capacitive touch equipment can be detected to be connected with the external equipment through the magnetic attraction contact, the touch key function can be shielded in time, the condition of mistouch is effectively isolated, and if the capacitive touch key is not detected to be connected with the external equipment, the key instruction corresponding to the capacitive touch key is responded. Whether a mode of being connected with external equipment exists is detected through the magnetic attraction contact of the capacitive touch equipment, if yes, whether the voltage of an IO control port connected with the corresponding magnetic attraction contact changes can be detected, namely whether a preset voltage value is reached, if yes, connection of the external equipment is indicated, or whether a handshake instruction sent by the external equipment is received by the IO control port connected with the corresponding magnetic attraction contact is detected, and if yes, connection of the external equipment is indicated.
The shielding method of the touch key is applied to the capacitive touch equipment connected with the external equipment through the magnetic attraction contact, detects whether the capacitance value corresponding to the capacitive touch key is increased to a preset capacitance value or not in the process of the adsorption connection with the external equipment, and shields the key function of the capacitive touch equipment if the capacitance value is not increased to the preset capacitance value. If yes, detecting whether the touch key is connected with the external equipment or not through a magnetic attraction contact of the capacitive touch equipment, and if yes, shielding the touch key function. The embodiment of the invention can combine various judgment factors to prevent misjudgment, thereby filtering the misoperation caused by external equipment and other external objects when the capacitive touch equipment is in contact connection with the external equipment through the magnetic attraction contact, and simultaneously ensuring that the capacitive touch equipment cannot be influenced by the normal use of the equipment due to the fact that the touch key is triggered by mistake caused by the adsorption and adhesion of the external equipment after connection. The invention can meet the operation and use requirements of the capacitive touch equipment for connecting the external equipment through the magnetic attraction contact, so that the capacitive touch equipment and the external equipment can realize stable information interaction transmission with strong anti-interference capability after being connected through the magnetic attraction contact.
In a specific embodiment, shielding the touch key function of the capacitive touch device, then comprises:
and receiving a user key instruction acquired by the external equipment connected with the magnetic contact.
According to the shielding method of the touch key provided by the embodiment of the invention, after the touch key function of the adsorbed capacitive touch equipment is shielded, the external equipment sends a user key instruction to the capacitive touch equipment, namely, the function of interaction with a user is transferred to the external equipment. The invention is convenient for the external equipment to adsorb the capacitive touch equipment through the magnetic attraction contact, thereby improving the stability and effectiveness of the external equipment and the capacitive touch equipment during communication connection, preventing the signal interference of the touch keys and ensuring the normal operation of the equipment.
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 a 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 plurality of capacitive touch keys are increased at the same time exists, namely the plurality of touch keys are touched at the same time. And in normal operation, the action that a plurality of keys are pressed simultaneously does not exist, therefore, even if the capacitance value corresponding to the capacitive touch key is detected to be increased to the preset capacitance value, in order to eliminate external interference factors to prevent misjudgment, whether the capacitance values corresponding to the capacitive touch keys are increased simultaneously can be detected through detecting, if yes, no response is made to shield the touch key function, if not, whether the capacitive touch key is connected with external equipment can be detected through the magnetic attraction contact of the capacitive touch equipment, if yes, the touch key function is shielded, otherwise, the key instruction corresponding to the capacitive touch key can be responded.
The embodiment of the invention can further reduce the false triggering condition of the touch key on the absorbed capacitive touch equipment caused by the pressing action of the external equipment when the external equipment is connected with the capacitive touch equipment through the magnetic attraction contact, and can improve the detection precision.
In a specific embodiment, "detecting whether capacitance values corresponding to a plurality of capacitive touch keys increase at the same time" further includes:
if the capacitance values corresponding to the plurality of capacitive touch keys are not detected to be increased at the same time, whether the capacitance values corresponding to the capacitive touch keys are kept unchanged or not is detected within a 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 invention only responds to the releasing transient state in the action of pressing and releasing the capacitive touch key, and shows that the capacitance value corresponding to the capacitive touch key is increased and then is restored to the original value in a short time. And the external equipment is not loosened by pressing after adsorbing the capacitive touch equipment through the magnetic attraction contact, and the capacitance value corresponding to the capacitive touch key is kept unchanged. Therefore, in the embodiment of the present invention, if it is not detected that the capacitance values corresponding to the plurality of touch keys are increased at the same time, in order to further exclude external interference factors and prevent erroneous determination, it may be detected whether the capacitance values corresponding to the capacitive touch keys remain unchanged within a preset time, and if so, no response is made to shield the touch key function. If not, detecting whether the capacitive touch device is connected with the external device or not through the magnetic contact of the capacitive touch device, if so, shielding the touch key function, and if not, responding to the key instruction of the corresponding capacitive touch key. Wherein the preset time is preferably 4s-6 s.
The embodiment of the invention can further reduce the false triggering condition of the touch key on the absorbed capacitive touch equipment caused by the overlapping action of the external equipment when the external equipment is connected with the capacitive touch equipment through the magnetic attraction contact, and can improve the detection precision and have 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 is separated from the capacitive touch key area 340 by a preset distance;
the method further comprises the following steps:
when the fact that the infrared induction intensity sensed by the infrared sensor is larger than or equal to a preset intensity threshold value is detected within a preset detection distance, the fact that an external device approaches and a touch key function is shielded is determined; 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 disposed in the capacitive touch device 10, and when there is an object on the surface of the capacitive touch device and the object is closer to the surface, the sensed infrared sensing intensity is stronger, so that the threshold value is reasonably set, and the capacitive touch device 10 is triggered to shield the touch key function when the external object is close to the preset detection distance. Wherein the preset detection distance is preferably 4cm-6 cm. When the capacitive touch device 10 is attracted to the external device through the magnetic attraction contact 310, the attracted capacitive touch device 10 gradually approaches the external device 20 and detects that the infrared induction intensity is greater than or equal to the preset intensity threshold within the preset detection distance, it is determined that the external device 20 approaches and shields the touch key function. For example, when the infrared induction intensity is greater than or equal to the preset threshold, the flag position 1 indicates that the external device 20 is determined to approach to shield the touch key function, a subsequent detection step of a capacitance value corresponding to the capacitive touch key is not required, otherwise, a subsequent related detection step is performed, so that misjudgment caused by external factors is prevented. The infrared sensor 330 is located beside the magnetic attraction contact 310 and separated from the capacitive touch key area 340 by a preset distance to avoid the normal operation range of the human hand, or the infrared induction intensity caused by the operation of the human hand on the touch key area 340 is not enough to reach a preset intensity threshold, so as to realize effective distinction.
The detection method of the embodiment of the invention is simple and easy to realize, can reduce program redundancy, and can effectively and quickly judge whether the external equipment 20 is to be adsorbed by the magnetic attraction contact of the capacitive touch equipment 10, thereby shielding the touch key function in time, saving an additional detection process and improving the detection sensitivity. Meanwhile, when the external device 20 is connected with the absorbed capacitive touch device 10 through a contact, false triggering response is prevented.
To further explain the shielding method of the touch key according to the embodiment of the present invention, as shown in fig. 2, when the capacitive touch key is connected to the external device through the magnetic attraction contact, in order to prevent the capacitive touch key on the capacitive touch device from being pressed by the external device and causing an incorrect response to affect the normal use, the method may be performed according to the following steps:
step S2: and detecting whether the infrared induction intensity sensed by the infrared inductor is greater than or equal to a preset intensity threshold value within a preset detection distance, if not, entering step S4, and if so, entering 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 so, entering step S6.
Step S6: whether the capacitance values corresponding to the plurality of capacitive touch keys are increased at the same time is detected, if so, the step S14 is executed, and if not, the step S8 is executed.
Step S8: and detecting whether the capacitance value corresponding to the capacitive touch key is kept unchanged within a preset time, if so, entering step S14, and otherwise, entering step S10.
Step S10: whether the capacitive touch device is connected with an external device or not is detected through the magnetic contact of the capacitive touch device, if so, the step S14 is executed, and if not, the step S12 is executed.
Step S12: and executing the key instruction.
Step S14: and shielding the touch key function.
The shielding method of the touch key provided by the embodiment of the invention can be combined with various judgment factors to prevent misjudgment, so that when the capacitive touch equipment is in contact connection with the external equipment through the magnetic attraction contact, misoperations caused by external equipment and other objects are filtered, and meanwhile, the condition that the normal use of the equipment is influenced due to the fact that the capacitive touch equipment is mistakenly triggered because of being adsorbed and attached by the external equipment can be avoided. The invention can meet the operation and use requirements of the capacitive touch equipment for connecting the external equipment through the magnetic attraction contact, so that the capacitive touch equipment and the external equipment can realize stable information interaction transmission with strong anti-interference capability after being connected through the magnetic attraction contact.
