Description
Technical Field
The application relates to the field of delay jitter elimination, in particular to a method, a device, a terminal and a storage medium for universal dynamic delay jitter elimination.
Background
The anti-shake is generally used for a mechanical elastic switch or a hot plug connector, and when the mechanical switch is opened, closed or the connector performs plug action, the system cannot effectively judge the high/low level state of the signal, namely the metastable state, for a period of time before the state of the signal is stable due to the instability of the manual operation and the instability of contacts of the mechanical elastic switch/connector. Taking the connector as an example, when the connector is plugged in, the signal will not immediately stabilize, and at the moment of plugging in, a series of jitters will accompany, which will lead to erroneous judgment of the signal state by the system. In order to avoid this, i.e. to correctly identify the plugging action of the mechanical spring switch and the connector, the jitter of the signal has to be handled.
The state machine is generally used for eliminating jitter, when the state transition and delay are carried out when the new state is detected to be different from the old state, the new state is detected after the delay, if the state is still unchanged, the state change is determined to be effective change, and the old state is assigned to be the new state and is output to the system.
Taking key operation as an example: the key operation can be divided into 4 states, namely a key press operation S0, a key press operation S1, a stable press operation S2, and a key release operation S3. Assume that the level is 0 when the key is pressed and 1 when not pressed. A key initial state S0, which indicates that no key is pressed, and S0 is maintained; when the key is pressed, the state goes to the state S1.
First, the initial state of the key is S0, and when an input of 1 is detected, it means that no key is pressed, and S0 is held. When the key input is 0, the key is pressed, and after the delay time, if the input is detected to be still 0, the state S1 is shifted; after the state S1 is shifted, the input is still 0 after the delay time is passed, and the S2 is continuously shifted; similarly, after the state S2 is shifted, the input is still 0 after the delay time is elapsed, and the state S3 is shifted, that is, the fact that the key is pressed is indicated, and the message can be transmitted to the system. In this process, any state detects an input of 1, indicating that the key operation was just disturbed, and not actually a key operation, the state switches back to S0. In the S3 state, the input is detected as high, i.e., there is a key release operation, and the state switches back to S0.
In the state transition process of S1-S3, each state needs to be delayed, and the delay processing of jitter elimination is generally 10ms or 20ms. The choice of the delay time is very important, if the delay time is too short, the state machine needs to judge for many times; if the delay time is too long, the judgment efficiency is low. However, on one hand, the current delay time is generally determined empirically, and on the other hand, different application scenes have different jitter elimination requirements, and accordingly, the state machine needs to configure a jitter elimination module for each application scene, so that the workload of a developer is increased.

Detailed Description
In order to better understand the aspects of the present application, the present application will be described in further detail with reference to the accompanying drawings and detailed description. It will be apparent that the described embodiments are only some, but not all, embodiments of the application. All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to be within the scope of the application.
Example 1
In the scene that the mechanical elastic switch or the hot plug connector and the like need to remove the tremble, a state machine is generally used for completing the tremble removal, when the fact that a new state is different from an old state is detected, state transition is carried out, time delay is carried out, the fact that the new state is detected after the time delay is carried out, if the state is still unchanged, the state change is determined to be effective change, and the old state is assigned to be the new state and is output to a system.
Taking key operation as an example: the key operation can be divided into 4 states, namely a key press operation S0, a key press operation S1, a stable press operation S2, and a key release operation S3. Assume that the level is 0 when the key is pressed and 1 when not pressed. A key initial state S0, which indicates that no key is pressed, and S0 is maintained; when the key is pressed, the state goes to the state S1.
First, the initial state of the key is S0, and when an input of 1 is detected, it means that no key is pressed, and S0 is held. When the key input is 0, the key is pressed, and after the delay time, if the input is detected to be still 0, the state S1 is shifted; after the state S1 is shifted, the input is still 0 after the delay time is passed, and the S2 is continuously shifted; similarly, after the state S2 is shifted, the input is still 0 after the delay time is elapsed, and the state S3 is shifted, that is, the fact that the key is pressed is indicated, and the message can be transmitted to the system. In this process, any state detects an input of 1, indicating that the key operation was just disturbed, and not actually a key operation, the state switches back to S0. In the S3 state, the input is detected as high, i.e., there is a key release operation, and the state switches back to S0.
In the state transition process of S1-S3, each state needs to be delayed, and the delay processing of jitter elimination is generally 10ms or 20ms. The choice of the delay time is very important, if the delay time is too short, the state machine needs to judge for many times; if the delay time is too long, the judgment efficiency is low. However, on one hand, the current delay time is generally determined empirically, and on the other hand, different application scenes have different jitter elimination requirements, and accordingly, the state machine needs to configure a jitter elimination module for each application scene, so that the workload of a developer is increased.
Therefore, the present embodiment provides a general dynamic delay jitter elimination method, which can dynamically adjust jitter elimination delay time of each operation, and can be suitable for various application scenarios by using one jitter elimination module.
Fig. 1 is a flow chart of a general dynamic delay jitter elimination method according to the embodiment, which includes the following steps.
S101, detecting whether the operation is a false operation.
I.e. detecting whether the operation is a disturbing operation or a normal operation, a disturbing operation, i.e. a fake operation, for example a key operation, the time of which is detected after the state S1 after a delay time as an input becomes 1, the operation being a disturbing operation, i.e. a fake operation. If the state goes to S3, the operation is normal.
S102, when the fake operation is detected, recording the fake operation times.
Note that the number of pseudo operations recorded is the number of accumulation. For example, if the first operation is a false operation, the number of times of the false operation is recorded as 1, and if the second operation is still a false operation, the number of times of the false operation is recorded as 1, that is, the number of times of the false operation is recorded as 2.
S103, adjusting the jitter elimination delay time of the next operation according to the recorded false operation times, and performing jitter elimination processing based on the adjusted jitter elimination delay time in the next operation.
If the false operation is met, the jitter elimination delay time of the next operation is timely adjusted, the accuracy of the next judgment is improved, and false detection is avoided.
According to the universal dynamic delay jitter elimination method provided by the embodiment, when false operation is detected, the false operation times are recorded, the jitter elimination delay time of the next operation is adjusted according to the recorded false operation times, and jitter elimination processing is performed based on the adjusted jitter elimination delay time in the next operation. The application can adjust the jitter elimination delay time according to the false operation times, so that the jitter elimination delay time is more reasonable, the judgment of a plurality of times is avoided, and the judgment accuracy is ensured; meanwhile, one jitter elimination module can be used for adapting to different application scenes, and the workload of developers is reduced.
Example two
Considering that the probability that the next false operation still occurs is still relatively high after a certain detection of the false operation, the embodiment adjusts the jitter-elimination delay time of the next operation according to the recorded number of false operations, and the adjusted jitter-elimination delay time is prolonged before adjustment.
Specifically, the debounce delay time for the next operation is calculated by the following formula:
delay n+1 =delay n + delay n *delaycounter/N
wherein, delay n Delay time for the jitter elimination of the nth operation n+1 The delay time is the jitter elimination delay time of the n+1th operation, the delay is the recorded false operation times, and N is the number of states experienced in the operation process.
For example, the key operation is performed through four states S0, S1, S2, and S3, so N is 4 in the above formula during the key operation. Of course, in other scenarios, the value of N is adjusted according to the number of states experienced by a particular operational process.
It should be noted that an initial value of the debounce delay time, i.e. the debounce delay time delay of the first operation, needs to be preset before detection 1 。
Still taking the key operation as an example, if the first operation is a false operation, recording the number of false operations as 1, and further calculating the jitter-elimination delay time of the second operation 2 =delay 1 + delay 1 *1/4. If the second operation is still a false operation, recording the number of times of the false operation as 2, and further calculating the jitter-elimination delay time delay of the third operation 3 =delay 2 + delay 2 *2/4。
Fig. 2 is a flow chart of a general dynamic delay jitter elimination method according to the embodiment, which includes the following steps.
S201, detecting whether the operation is a false operation.
S202, when the fake operation is detected, recording the fake operation times.
S203, delay according to the formula n+1 =delay n + delay n * The delycounter/N calculates the debounce delay time for the next operation.
The general dynamic delay jitter elimination method provided by the embodiment records the false operation times when the false operation is detected, and based on the formula delay according to the recorded false operation times n+1 =delay n + delay n * The delycounter/N adjusts the jitter elimination delay time of the next operation, and the jitter elimination processing is carried out based on the adjusted jitter elimination delay time in the next operation. The application can adjust the jitter elimination delay time according to the false operation times, so that the jitter elimination delay time is more reasonable, the judgment of a plurality of times is avoided, and the judgment accuracy is ensured; meanwhile, one jitter elimination module can be used for adapting to different application scenes, and the workload of developers is reduced.
Example III
After the normal operation is detected, the probability of the next normal operation is larger, so that the recorded false operation times are cleared in time after the normal operation is detected, and the jitter elimination delay time of the next operation is correspondingly adjusted to be the initial jitter elimination delay time, namely, the recording of the false operation times and the adjustment of the jitter elimination delay time are carried out again.
Fig. 3 is a flow chart of a general dynamic delay jitter elimination method according to the embodiment, which includes the following steps.
S301, detecting whether the operation is a false operation.
S302, when the fake operation is detected, recording the fake operation times.
S303, delay according to the formula n+1 =delay n + delay n * The delycounter/N calculates the debounce delay time for the next operation.
Wherein, delay n Delay time for the jitter elimination of the nth operation n+1 The delay time is the jitter elimination delay time of the n+1th operation, the delay is the recorded false operation times, and N is the number of states experienced in the operation process.
S304, after the false operation is detected, when the normal operation is detected once, the recorded false operation times are cleared.
S305, when the recorded false operation times are zero, setting the jitter elimination delay time of the next operation as the initial jitter elimination delay time.
It should be noted that, except when the recorded number of false operations is zero, that is, when the previous false operation is changed to the normal operation of the previous time, the jitter-elimination delay time of the next operation is set to be the initial jitter-elimination delay time, otherwise, the jitter is eliminated according to the formula n+1 =delay n + delay n * The delycounter/N calculates the debounce delay time for the next operation.
The general dynamic delay jitter elimination method provided by the embodiment records the false operation times when the false operation is detected, and based on the formula delay according to the recorded false operation times n+1 =delay n + delay n * The delycounter/N adjusts the jitter elimination delay time of the next operation, and the jitter elimination processing is carried out based on the adjusted jitter elimination delay time in the next operation. In addition, after the false operation is changed into normal operation, the recorded false operation times are cleared in time, andthe jitter elimination delay time of the next operation is set as the initial jitter elimination delay time, so that the state detection efficiency is improved. The application can adjust the jitter elimination delay time according to the false operation times, so that the jitter elimination delay time is more reasonable, the judgment of a plurality of times is avoided, and the judgment accuracy is ensured; meanwhile, one jitter elimination module can be used for adapting to different application scenes, and the workload of developers is reduced.
Example IV
In order to solve the problems that the delay time is generally determined empirically and different application scenes have different jitter elimination requirements, and accordingly, a state machine needs to configure a jitter elimination module for each application scene and increase the workload of developers, the embodiment provides a universal dynamic delay jitter elimination device which can dynamically adjust the jitter elimination delay time of each operation and can be suitable for various application scenes by using one jitter elimination module.
