This non-provisional patent application claims priority under 35 USC. § 119 from Chinese Patent Application No.202111117678.4 filed on Sep. 23, 2021, the entire content of which is incorporated herein by reference.

TECHNICAL FIELD

The disclosure relates to sensor technology, in particular to a synchronous joystick sensor, a controller, and a synchronous processing method.

BACKGROUND

Joystick sensors are commonly used in electronic products such as game controllers and consumer drone controllers. The joystick generally includes a joystick, a joystick arm that rotates according to the tilting operation of the joystick (containing upper joystick arm and a lower joystick arm arranged perpendicular to each other) and a variable resistance component that detects the amount of rotation of the joystick arm. The variable resistance component will output a corresponding output signal according to the amount of rotation of the joystick arm. At the same time, a reset component is provided under the joystick arm to ensure the joystick and joystick arm to reset automatically. The joystick sensor can be restored to a original state under the action of the reset component when the operation applied to the joystick is ended.

However, the above-mentioned variable resistance components usually use external force to move the brush on the carbon resistor to produce different resistance values on the circuit board. If a metal with greater elasticity is used as the brush, the brush wears quickly and has a short service life. If a metal with less elasticity is used as a brush, the problem of poor contact and failure between the brush and the carbon resistor is likely to occur. And if a high-hardness carbon resistor is used, the brush will wear out quickly and cause greater electronic noise. If a low-hardness carbon resistor is used, the carbon powder on the carbon resistor will be quickly worn off by the brush, and the carbon powder will stick to the brush, which affects the electronic performance of the brush and makes the potentiometer appear abnormal function. Therefore, the typical potentiometer generally has defects of short service life and poor performance.

In addition, the existing circuit boards are generally bulky and the reset assembly structure is complex, which leads to an increase in the gap between the joystick sensor components and the structure is not tight, which affects the direction operation experience of the joystick sensor, and also causes the joystick to swing and the rotation of the variable resistance components not be synchronized well, and the control accuracy is low.

Therefore, there is room for promotion in joystick sensor technology.

This embodiment provides a controller, including the synchronous joystick sensor of Embodiment 1 or Embodiment 2, which has the advantages of long service life, miniaturization, good synchronization, and automatic reset sensitivity.

This embodiment provides a synchronization processing method for a synchronized joystick sensor, as shown inFIG.13, including the following steps.

In step S1, determining whether the electronic signal set output by the piezoelectric ceramic component7of the synchronous joystick sensor in Embodiment2is received; when it is not received, it means that the joystick is not pushed, and the joystick is in an upright state, and maintaining an upright state.

In step S2, when the electronic signal set is received, determining whether the first electronic signal output by the first magnetic induction element213or the second electronic signal output by the second magnetic induction element223is received while the electronic signal set is received.

In step S3, when the first electronic signal output by the first magnetic induction element213or the second electronic signal output by the second magnetic induction element223is received at the same time as the electronic signal set is received, determining the first electronic signal output by the first magnetic induction element213or the second electronic signal output by the second magnetic induction element223to be the detection output signal of the synchronous joystick sensor and output the detection output signal. In detail, when the first electronic signal output by the first magnetic induction element213or the second electronic signal output by the second magnetic induction element223is received at the same time as the electronic signal set is received, it indicates that the swing of the joystick and the magnetic induction element is sensed and the swing has synchronization, so no correction is needed. The first electronic signal output by the first magnetic induction element213or the second electronic signal output by the second magnetic induction element223is used as the detection output signal of the synchronous joystick sensor and output.

In step S4when the first electric signal output by the first magnetic induction element213or the second electric signal output by the second magnetic induction element223is not received when the electric signal set is received, the electronic signal set is input to a first trained neural network model to calculate a pushing force direction and a pushing force value of a pushing force acting on the joystick1corresponding to the electronic signal set; the input of the first neural network model is the electronic signal set, the output is the direction and value of the pushing force acting on the joystick1corresponding to the electronic signal set. Preferably, the first neural network model is a basis function neural network model (BF) neural network model, an radial basis function neural network model (RBF) neural network model, and the like. It is understood that, when the first electric signal output by the first magnetic induction element213or the second electric signal output by the second magnetic induction element223is not received while the electric signal set is received, it means that the magnetic induction element starts to swing when the joystick is forced to swing, if the swing is not sensed for immediately, it is possible that the sensing of the magnetic induction element has a lag, and there is no synchronization. When the magnetic induction element output the electronic signals, the joystick has already swung a certain angle, so it needs to be corrected at this time.

In step S5, determining the first electronic signal or the second electronic signal that needs to be supplemented according to the pushing force direction, and input the pushing force value into a second trained neural network model or a third trained neural network model to calculate the first electronic signal or the second electronic signal that needs to be supplemented output, the first electronic signal or the second electronic signal that needs to be supplemented output is used as the detection output signal of the synchronous joystick sensor and output; the input of the second neural network model is the pushing force value, and the output is the first electronic signal that needs to be supplemented; the input of the third neural network model is the pushing force value, and the output is the second electronic signal that needs to be supplemented. That is to say, there is first determined whether the swing direction of the joystick is the first direction or the second direction according to the pushing force direction, if it is the first direction, there is then input the pushing force value into the second neural network model, and output the first electronic signal that needs to be supplemented. If it is the second direction, the pushing force value is input to the trained third neural network model, and the second electronic signal that needs to be supplemented is output. Preferably, the second neural network model and the third neural network model are BF neural network models, RBF neural network models, and the like.

In the step S6, determining whether the first electronic signal output by the first magnetic induction element213or the second electronic signal output by the second magnetic induction element223is received. When the first electronic signal output by the first magnetic induction element213or the second electronic signal output by the second magnetic induction element223is not received, it means that it is still in the hysteresis stage, maintain the current status, and continue to use the first electronic signal or the second electronic signal need to be supplemented as the detection output signal of the synchronous joystick sensor and output the first electronic signal or the second electronic signal need to be supplemented.

In the step S7, when the first electronic signal output by the first magnetic induction element213or the second electronic signal output by the second magnetic induction element223is received, the first electronic signal output by the first magnetic induction element213or the second magnetic induction element223is used as the detection output signal of the synchronous joystick sensor and output, so as to replace the first electronic signal or the second electronic signal need to be supplementary output by the synchronous joystick sensor when the first magnetic induction element213or the second electronic signal output by the second magnetic induction element223is not received. The signal actually detected by the first or second magnetic induction element is used as the output to end the hysteresis correction process, because the signal predicted by the neural network is used to as the output signal of the synchronous joystick sensor during the lag time, the blank output of the lag process is filled, and the synchronization is improved.
