The intelligent peripheral of the present invention will be described in detail with reference to fig. 1-19.
In this embodiment, the intelligent peripheral includes: communication subassembly, rectifier circuit Unit, steady voltage Unit, bluetooth Unit, MCU (Microcontroller Unit, little the control Unit) and input Unit, the communication subassembly includes NFC (Near field communication) Unit, MCU respectively with the NFC Unit, rectifier circuit Unit, steady voltage Unit, the input Unit is connected, the input of rectifier circuit Unit, the output respectively with the NFC Unit, steady voltage Unit connection, the intelligence peripheral hardware is through the NFC Unit with radio frequency signal conversion for the electric current, utilize rectifier circuit Unit and steady voltage Unit to rectify the electric current respectively, supply power to MCU after the steady voltage to be connected with intelligent terminal through the communication subassembly.
The intelligent peripheral of this embodiment converts the radio frequency signal that intelligent terminal sent into the electric current power supply through the NFC unit and accomplishes the MCU and other components power supply to intelligent peripheral (for example to bluetooth unit power supply). Meanwhile, the NFC unit can be used as a communication unit, or the powered Bluetooth unit can be used as a communication device of an intelligent peripheral to communicate with other intelligent terminals.
In this embodiment, the radio frequency signal sent by the smart terminal refers to a 13.56MHZ radio frequency signal used in the NFC unit communication.
In this embodiment, the smart terminal is a mobile phone and other devices having NFC devices.
In this embodiment, establish to any one of game controller, the cell-phone shell of controlling in the area, the peripheral hardware of the cell-phone shell of NFC power supply, the luminous cell-phone shell outside intelligence.
The intelligent peripheral of the present invention is described in detail below by taking an example in which the intelligent terminal is a mobile phone and the intelligent peripheral is a game controller.
In this embodiment, when the mobile phone does not sense the NFC tag, the frequency or the intensity of the radio frequency signal sent by the smart terminal is usually insufficient by default due to energy saving considerations, and at this time, the power of the electrical signal converted by the NFC unit is too low to be used for activating or supplying the external device. Therefore, the NFC unit comprises a maintaining circuit which comprises a coil and an NFC label, and when the mobile phone is in contact with the intelligent peripheral, the mobile phone senses the NFC label, so that the mobile phone is triggered to send out a stable radio frequency signal with enough power to obtain current capable of being used by the intelligent peripheral.
In this embodiment, the maintaining circuit is a part of the NFC unit, and in other embodiments, the maintaining circuit may be a separate module (such as an NFC tag sticker) having a chip of an NFC tag and a coil. In this embodiment, the reversing block 13 and the handle rotating member 7 are circular, and in other embodiments, the reversing block 13 and the handle rotating member 7 may also be in other shapes, which is not limited herein.
In this embodiment, in order to convert the radio frequency signal transmitted by the mobile phone into an electric current, the NFC unit further comprises at least one resonant antenna or a conversion coil, through which the radio frequency signal is converted into an electric current. Wherein the coil of the maintaining circuit can also be used to convert the radio frequency signal of the handset into a current.
In this embodiment, the rectifier circuit unit receives the alternating current transmitted by the NFC unit and converts the alternating current into direct current through the rectifier circuit unit; the rectifier circuit unit comprises a full-bridge rectifier circuit and an N voltage doubling rectifier circuit, wherein N is not less than 1.
In this embodiment, since the NFC unit includes a plurality of antennas or coils for converting energy, the collected signal strength may be different according to the distance sequence from the region transmitting the signal, and the voltages of the electrical signals converted by different antennas or coils may also be different. A rectifying circuit unit is required to perform different processes according to the voltage output from the antenna or the coil. According to the voltage condition, the rectification is carried out by one of full-wave rectification and voltage-doubling rectification or a combination mode of the full-wave rectification and the voltage-doubling rectification. Wherein, the full-wave rectification has high energy conversion rate and small voltage change (for example, half-wave has energy conversion efficiency of less than 50%); the voltage doubling rectification can amplify the voltage of the electric signal, so that the loss of the electric signal is small under high voltage. Since the electrical signals are attenuated in sequence, the electrical signals with higher voltage may not be subjected to voltage doubling rectification.
The electric signals output by the antennas or the coils are rectified by the rectifying circuit unit, and then the rectified electric signals are output in a parallel connection mode.
The rectified electrical signals may have different voltages or currents (for example, the voltages and currents may be different between the voltage-doubling rectified voltage and the voltage-doubling rectified non-voltage-doubling rectified voltage). Therefore, the voltage output by the rectifying circuit unit may not be stable, and the voltage stabilization processing by the voltage stabilization unit is required.
In this embodiment, the voltage stabilizing unit includes a DC-DC circuit and/or an LDO circuit, and the DC-DC circuit is connected to the rectifying circuit unit and the MCU respectively. The LDO circuit can be connected with the DC-DC circuit or directly connected with the rectifying circuit unit.
The DC-DC circuit can output low-voltage high-current electric signals, and the electric signals can reduce load loss and provide voltage required by the intelligent peripheral for working so as to ensure the normal working of the intelligent peripheral. If the working voltage of the chip of the intelligent peripheral is 1.8V, the DC-DC circuit can output 1.8V voltage, so that the requirement of the working voltage of the intelligent peripheral is met, and more stable and sufficient current guarantee can be provided.
In the embodiment, the DC-DC circuit comprises a DC-DC chip and a peripheral element circuit, and the unstable voltage output by the rectifying circuit unit is converted into stable voltage and current output through the DC-DC circuit, so that the loss of the intelligent peripheral is reduced.
In this embodiment, the LDO circuit is composed of a circuit including an LDO chip and peripheral components, and is intended to output a voltage linearly to a device requiring a small power supply ripple and requiring high accuracy of an electric signal, such as a rocker of a controller in an intelligent peripheral device, which is collected by an ADC.
In this embodiment, the LDO circuit may be directly connected to the rectifier circuit unit or connected to the rectifier circuit unit through a DC-DC circuit. The difference is that the LDO circuit is a consumable element, and the conversion efficiency of the electric signal is low after the LDO circuit is directly connected with the rectifying circuit unit; when the electric signal is transmitted to the LDO circuit after being subjected to voltage stabilization by the DC-DC unit, the conversion efficiency of the LDO circuit is high.
In this embodiment, the intelligent peripheral receives an input signal through the input unit. The input unit comprises at least one of a key and/or a rocker, a gyroscope and other devices used for inputting information to the MCU, and is respectively connected with the MCU and the voltage stabilizing unit and supplies power to the input unit through the voltage stabilizing unit.
In a specific embodiment, the input unit comprises a rocker and a key, wherein the rocker is connected with the LDO circuit, and power is supplied to the rocker through the LDO circuit; the keys and the rocker are respectively connected with the MCU, and the MCU finishes the acquisition action of input signals through devices such as IO, GPIO, ADC, SPI, I2C, UART and the like.
In this embodiment, the intelligent peripheral includes a display unit, the display unit is respectively connected to the MCU and the DC-DC circuit, and the MCU displays the operating state of the intelligent peripheral through the display unit.

And the Bluetooth unit can be used as a communication unit of the intelligent peripheral and the terminal, so that the purpose of using the intelligent peripheral as an input device (NFC power supply and Bluetooth communication) of the intelligent terminal is achieved.
In other embodiments, the communication components may also include infrared, WiFi, and other devices capable of communicating with a cell phone.
In the above embodiments, one or more of the communication module, the MCU, the rectifier circuit unit, the voltage regulator unit, and the input unit may be integrated in one SOC (i.e., the above units are replaced by SOCs having the same function), or may be separately or in combination provided in a plurality of different SOCs.
In this embodiment, the NFC unit itself may serve as a communication unit, and the intelligent peripheral performs data communication with the mobile phone through an NFC protocol; since the data transmitted by the NFC unit are typically NDEF and non-NDEF data, which cannot be directly recognized by the game or APP as handling data (non-input), the received NFC data can be converted into input operation signals which can be recognized by games or APP through the mobile phone, such as HID key values, touch (such as multi-touch) operation signals and the like, for example, an input operation ticket signal is described as a signal input by an HID (human interface device) device of a game controller, a keyboard, a touch device and the like, NFC (near field communication) data is converted into an HID data format type and reported to the HID device, the HID data is processed into a corresponding standard HID signal transmission application layer by a mobile phone, and the data is converted into a touch signal format which can be recognized by an intelligent terminal (for example, an android mobile phone can be converted into a Motionvent, coordinate and the like format, the touch signal format is processed through an InputManager inputEvent, a sensory, a monkey or Framework layer, and finally a corresponding touch signal Motion Event is received through an OntouchListener and an onTouch layer in the application layer).
