It is to be understood that the data so used may be interchanged where appropriate such that the embodiments of the invention described herein may be implemented in sequences other than those illustrated or otherwise described herein.

Example 1
In accordance with an embodiment of the present invention, there is provided a method embodiment of identifying knob operation, it being noted that the steps shown in the flowchart of the figures may be performed in a computer system, such as a set of computer executable instructions, and, although a logical order is shown in the flowchart, in some cases, the steps shown or described may be performed in an order other than that shown or described herein.
FIG. 1 is a flowchart of a method of identifying knob operation, as shown in FIG. 1, according to an embodiment of the invention, the method comprising the steps of:
step S102, detecting the inductance of all coils on the wire controller every preset time period in the process of installing or detaching the knob on the wire controller, and obtaining the total inductance of all coils on the wire controller.
Specifically, in the above steps, the knob is placed on the wire controller panel; the knob is taken off from the panel of the wire controller, the total inductance of the coil is the inductance of all induction coils on the knob, the wire controller detects the inductance of each induction coil once every preset time period, and the total inductance of the coils is calculated.
It should be noted that, when the knob is mounted on the wire controller panel, the inductance of each coil will change when the knob is rotated to different positions, but the sum of the inductances of all coils is within a certain range (the difference between the sums at different positions is caused by the incomplete symmetry of the circuit layout and the incomplete flush of the assembly of each coil).
In an alternative embodiment, the preset time period may be 100ms.
Step S104, judging whether the total inductance of the coil meets the preset condition.
Specifically, in the above step, the preset condition may be used to determine an operation state of the knob, where the operation state at least includes: an installing state, an uninstalling state, an installed state and an uninstalled state; and calculating the total inductance of all coils on the wire controller according to the detected inductance of each coil.
Step S106, determining the current operation state of the knob according to the judgment result, wherein the operation state at least comprises: an installing state, an uninstalling state, an installed state and an uninstalled state.
Specifically, in the above steps, after the total coil inductance of all the coils on the current wire controller is obtained, determining the current operation state of the knob according to the preset condition satisfied by the total coil inductance, so as to determine whether the rotation operation of the knob is effective operation according to the current operation state of the knob.
As can be seen from the above, in the above embodiment of the present application, during the process of installing or dismantling the knob on the wire controller, the inductance of all the coils on the wire controller is detected by the preset time period, and the operation state of the current knob is determined according to the total inductance of the coils of the current wire controller, so as to determine whether the rotation operation of the knob is effective operation according to the current operation state of the knob, and only when the current operation state of the knob is the installed state, the rotation operation of the knob is determined to be effective operation, thereby achieving the purpose of identifying the current operation state of the knob during the installation and dismantling of the knob, and determining whether the rotation operation of the knob is effective operation according to the operation state, thereby achieving the technical effect of reducing the misoperation caused by the installation and dismantling of the knob, and further solving the technical problem of misoperation of the existing rotation button for controlling electrical equipment during the installation and dismantling of the knob.
In an alternative embodiment, before determining whether the total inductance of the coil meets the preset condition, the method may further include the steps of:
step 101, recording the maximum value and the minimum value of the total inductance of all coils on the wire controller by rotating the knob for one circle.
In an alternative embodiment, the preset conditions include at least any one of the following:
the total inductance of the coil on the current detected wire controller is larger than the maximum value, the total inductance of the coil on the current detected wire controller is between the minimum value and the maximum value, and the absolute value of the difference value between the total inductance of the coil on the current detected wire controller and the total inductance of the coils on the last detected wire controller is larger than a preset threshold value, wherein the preset threshold value is larger than the difference value between the maximum value and the minimum value.
The preset threshold may be a preset difference value greater than a maximum coil total inductance value of the wire controller and a minimum coil total inductance value of the wire controller.
In an alternative embodiment, as shown in fig. 2, according to the determination result, determining the current operating state of the knob may include the following steps:
step 202, if the total inductance of the coil on the wire controller detected currently is greater than the maximum value, determining that the current operating state of the knob is a disassembled state;
Step 204, if the total inductance of the coil on the wire controller detected currently is between the minimum value and the maximum value, determining that the current operation state of the knob is an installed state;
in step 206, if the absolute value of the difference between the total inductance of the coils on the currently detected wire controller and the total inductance of the coils on the last detected wire controller is greater than a preset threshold, determining that the current operating state of the knob is in the installation state and/or in the removal state.
Specifically, in the above steps, the maximum value is the maximum total inductance value of the total inductance values of all coils on the wire controller recorded by rotating the knob one circle; the minimum value is the minimum total inductance value in the total inductance values of all coils on the wire controller through rotating the knob for one circle; after detecting the current total inductance of all coils on the wire controller and calculating to obtain the current total inductance of the coils of the wire controller, judging a preset condition met by the current total inductance of the coils of the wire controller, and if the current total inductance of the coils of the wire controller is greater than the maximum total inductance of the wire controller, considering the current operating state of the knob to be a disassembled state; if the current total inductance of the coil of the wire controller is between the minimum total inductance and the maximum total inductance of the wire controller, determining that the current operating state of the knob is an installed state; and if the absolute value of the difference value between the current coil total inductance of the wire controller and the coil total inductance of all coils on the wire controller detected last time is larger than a preset threshold value, determining that the current operating state of the knob is in an installing state and/or in a detaching state.
When the knob is detached from the wire controller, the inductance of the coil is changed by no object in front of the coil, so that the sum of the inductances of all the coils is larger than that of the knob when the knob is mounted.
In an alternative embodiment, the maximum value may be a maximum total inductance value of the wire controller plus the first error value, and the minimum value may be a minimum total inductance value of the wire controller minus the second error value.
In an alternative embodiment, as shown in fig. 3, after determining, according to the determination result, the current operating state of the knob, the method may further include the following steps:
step 302, if the current operating state of the knob is the installed state, determining that the current rotating operation of the knob is a normal rotating operation;
step 304, if the current operating state of the knob is any one of the following states: the current rotation operation of the knob is determined to be an ineffective rotation operation in the mounting state, the dismounting state and the dismounted state.
Specifically, in the above step, if the operation state in which the knob is currently located is the installed state, the knob is considered to be installed on the panel of the wire controller, and the current rotation operation of the knob is determined as the normal rotation operation; if the current operating state of the knob is any one of the mounting state, the dismounting state and the dismounted state, the knob is not on the wire controller panel, and the current rotating operation of the knob is determined to be an ineffective rotating operation.
With the above embodiment, it is possible to prevent the knob from being erroneously recognized as a rotating operation during the mounting or dismounting.
In an alternative embodiment, as shown in fig. 4, after determining that the operation state in which the knob is currently located is the installed state, the method may further include the steps of:
step 402, judging whether the difference between the total inductance of all coils on the wire controller detected last time and the total inductance of all coils on the wire controller detected currently is larger than a preset threshold, wherein the preset threshold is larger than the difference between the maximum value and the minimum value;
step 404, if the difference between the total inductance of all coils on the last detected wire controller and the total inductance of all coils on the current detected wire controller is greater than a preset threshold, determining that the current operating state of the knob is the state just installed.
Specifically, in the step, the preset threshold may be a preset difference value greater than a maximum coil total inductance value of the wire controller and a minimum coil total inductance value of the wire controller; after the current operating state of the knob is determined to be the installed state, judging whether the difference value between the total coil inductance of all coils on the wire controller detected last time and the total coil inductance of all coils on the wire controller detected currently is larger than a preset threshold value, and if the difference value between the total coil inductance of all coils on the wire controller detected last time and the total coil inductance of all coils on the wire controller detected currently is larger than the preset threshold value, determining that the current operating state of the knob is the state just installed.
In an alternative embodiment, as shown in fig. 5, after determining that the operation state in which the knob is currently in the just-installed state, the method may further include the steps of:
step 502, determining the current rotation operation of the knob within a preset time as an ineffective rotation operation;
and 504, after the preset time is over, determining the current rotation operation of the knob as a normal rotation operation.
Specifically, in the above steps, after it is determined that the operation state in which the knob is currently in the state of just being mounted, counting is started from this moment, the detected knob rotation operation is regarded as invalid in a time counted less than a preset time (a typical value may be 2S), and when the counted time is greater than the preset time, the normal detection knob rotation operation is started.
By the embodiment, misoperation caused by knob shaking generated immediately after the knob is mounted on the panel of the wire controller can be prevented.
The above-described embodiment may be described in connection with fig. 6 as a preferred implementation, fig. 6 is a flow chart of a preferred method of identifying knob operation in accordance with an embodiment of the present invention; as shown in fig. 6, the method comprises the following steps:
in step S602, the maximum value Hb and Hs of the sum of the inductance of all the coils when the knob is mounted on the wire controller is recorded.
Specifically, in the above steps, when the knob is mounted on the wire controller panel, the inductance of each coil is changed when the knob is rotated to different positions, but the total of the inductances of all coils is within a certain range (the difference in the total is due to the incomplete symmetry of the circuit layout of each coil and the incomplete flush of the assembly), the maximum value Hb and the minimum value Hs of the total of the inductances of all coils can be recorded by one rotation.
In step S604, the sum Hn of the inductance values of all coils after the knob is detached from the wire controller is recorded, wherein Hn > hb+h1> Hs-H2.
Specifically, in the above steps, when the knob is detached from the wire controller, since there is no object in front of the coil to change the inductance of the coil, the sum of the inductance of all coils is larger than that at the time of knob mounting, and is recorded as Hn, where Hn > hb+h1> Hs-H2, through the test.
In step S606, the wire controller detects the inductance of each induction coil once every T1 time, and calculates the sum of the inductances of all coils as h, and the sum of the electric quantities of all coils detected last time as hL.
Specifically, in the above steps, the wire controller detects the inductance of each induction coil once every T1 (typically 100 ms) time, and calculates the sum of the inductances of all coils as h, and the sum of the inductances of all coils detected last time as hL.
Step S608, it is determined whether H > hb+h1 is satisfied.
Specifically, in the above step, it is judged whether the sum of all coil inductance amounts currently detected is H satisfying H > hb+h1; if H > Hb+H2 is satisfied, then step S610 is performed; otherwise, step S612 is performed.
In step S610, it is determined that the knob is not on the line controller panel, and at this time, the knob rotation operation is not detected.
Specifically, in the above step, if the sum of all the coil inductance amounts currently detected is H satisfying H > hb+h1, it is considered that the knob is not above the wire controller panel (i.e., the knob has been detached), at which time the knob rotation operation is not detected.
Step S612, it is determined whether |h-hL| > hc and h > Hb are satisfied.
Specifically, in the above step, if the sum of all the coil inductance amounts currently detected is H, which does not satisfy H > hb+h1, it is determined whether H satisfies |h-hl| > hc and H > Hb, and if so, step S614 is performed, and otherwise, step S616 is performed.
In step S614, it is determined that the knob is being attached or detached, and the detected knob operation is regarded as invalid.
Specifically, in the above steps, if |h-hl| > Hc and h > Hb (where Hc > Hb-Hs) are considered to be the knob being attached or detached, the difference between the sum of inductance values of all coils detected twice is greater than Hb-Hs because the distance between the copper sheet on the knob and the coil varies during the attachment and detachment of the knob. The knob rotation operation detected at this time is regarded as invalid, preventing the process of attaching or detaching the knob from being erroneously recognized as a rotation operation.
Step S616, judging whether hL-h > hc and Hb is greater than or equal to h and greater than or equal to Hs are satisfied.
Specifically, in the above step, if h does not satisfy |h-hl| > hc and h > Hb, it is determined whether h satisfies hL-h > hc and Hb is greater than or equal to h is greater than or equal to Hs, and if so, step S622 is performed; otherwise, step S618 is performed.
Step S618, judging whether Hb+H21 is more than or equal to H is more than or equal to Hs-H2.
Specifically, in the above step, if H does not satisfy hL-H > hc and Hb is greater than or equal to H is greater than or equal to Hs, judging whether H satisfies Hb+H2 is greater than or equal to H is greater than or equal to Hs-H2; if so, executing step S620; otherwise, step S606 is performed.
In step S620, the knob is determined to be above the line controller panel, and the knob operation is normally detected.
Specifically, in the above steps, if H satisfies Hb+H21.gtoreq.h.gtoreq.Hs-H2, the knob is considered to be on the wire controller panel (i.e. the knob is mounted on the wire controller), and at this time, the knob rotating operation is normally detected. Wherein H1 and H2 are both less than Hs, and Hn > Hb+H2 > Hs-H2.
Preferably, H1 and H2 may be h1=h2= (Hb-Hs) 50%.
Step S622, determining that the knob has just been installed, and starting timing from that point on.
Specifically, in the above step, if hL-h > Hc and hb.gtoreq.h.gtoreq.hs are satisfied, it is considered that the knob has just been installed and the time is counted from this moment.
In step S624, it is determined whether the timer is greater than the time T2.
Specifically, in the above step, it is determined whether the timer is greater than the time T2, and if the timer is greater than T2, step S606 is performed; otherwise, step S626 is performed.
In step S626, the detected knob operation is regarded as invalid.
Specifically, in the above steps, the detected knob rotation operation is regarded as invalid in a time of less than the time T2 (typically 2S), preventing malfunction caused by knob shake generated immediately after the knob is mounted on the drive-by-wire panel, and starting the normal detection knob rotation operation after the time is greater than the time T2.
Through the embodiment, the program algorithm processing can avoid misoperation of the knob in the process of mounting and dismounting.

As can be seen from the above, in the above embodiment of the present application, during the process of installing or dismantling the knob on the wire controller, the inductance of all the coils on the wire controller is detected by the preset time period, and the operation state of the current knob is determined according to the total inductance of the coils of the current wire controller, so as to determine whether the rotation operation of the knob is effective operation according to the current operation state of the knob, and only when the current operation state of the knob is the installed state, the rotation operation of the knob is determined to be effective operation, thereby achieving the purpose of identifying the current operation state of the knob during the installation and dismantling of the knob, and determining whether the rotation operation of the knob is effective operation according to the operation state, thereby achieving the technical effect of reducing the misoperation caused by the installation and dismantling of the knob, and further solving the technical problem of misoperation of the existing rotation button for controlling electrical equipment during the installation and dismantling of the knob.
