In the present specification, the sizes of the respective portions shown in the drawings are not drawn in an actual proportional relationship for the convenience of description.
Fig. 1 and 2 are connection diagrams of devices included in the system for intelligent remote control and charging of the present invention.
As shown in fig. 1 and 2, the system includes a terminal device 11, a remote control transmission device 12, a remote control reception device 13, and a mobile device 21.
The terminal equipment at least comprises a USB interface and is loaded with a microprocessor, so that some simple control functions can be realized, but the terminal equipment without a controllable screen is not provided. For example, the intelligent desk lamp can control the on-off of the desk lamp and the light intensity of the light through a built-in chip; the intelligent fan can control the rotating speed and the orientation of the fan through the built-in chip.
Preferably, the remote control transmitting device is a device capable of transmitting at least 2.4GHz wireless radio frequency signals. Specifically, the remote control transmitting device comprises a 2.4GHz radio frequency transmitting chip, a 4.2V battery, an LDO battery chip with a 3.3V output and a transmitting antenna. The 2.4GHz radio frequency transmitting chip has a singlechip function, can be programmed, and is provided with a plurality of input and output ports and at least one input key; the 4.2V battery can provide a working power supply for the remote control transmitting equipment; the LDO battery chip with 3.3V output is used for converting 4.2V battery voltage into 3.3V voltage required by a 2.4GHz radio frequency transmitting chip, and the transmitting antenna is used for transmitting 2.4GHz wireless radio frequency signals.
Preferably, the remote control receiving device is a device which can receive at least 2.4GHz wireless radio frequency signals and at least has one connectable USB interface. Specifically, the remote control receiving device comprises a 2.4GHz radio frequency receiving chip, a 5V level-to-3.3V conversion chip and a receiving antenna. Wherein, the 2.4GHz radio frequency receiving chip has the function of a singlechip, can be programmed and is provided with a plurality of input and output ports,
the output port of the remote control device can be connected with a USB interface, and remote control signals received by the 2.4GHz radio frequency receiving chip are output to a control single chip of the terminal device; the conversion chip is used for converting the 5V level out of 3.3V, and the receiving antenna is used for receiving 2.4GHz wireless radio frequency signals.
The mobile device is various electronic devices having at least one port connectable to the USB interface, including but not limited to smart phones, tablet computers, e-book readers, portable notebooks, desktop computers, and the like.
The intelligent remote control and charging system comprises two connection modes.
As shown in the left side of fig. 1, a USB interface of a terminal device is connected to a remote control receiving device, the remote control receiving device is connected to a remote control transmitting device in a wireless manner, and a working mode corresponding to the connection mode is a remote control mode;
as shown by the dotted line on the right of fig. 1, the same USB interface of the terminal device is connected to the mobile device to charge the mobile device, and the operating mode corresponding to the connection mode is a charging mode.
It should be noted that the remote control transmitting device 12 and the mobile device 14 may be different devices or the same device, but the device requirements and the connection requirements are satisfied at the same time. That is, for the current USB interface, if the working mode corresponding to the interface connection mode is the remote control mode, the remote control transmitting device may also be a mobile device, and wirelessly pairs with the remote control receiving device, and transmits a 2.4GHz wireless radio frequency signal to the remote control receiving device connected to the USB interface, and in addition, since the USB interface is already connected to the remote control receiving device, it is impossible to connect to the mobile device or the remote control transmitting device to charge the mobile device or the remote control transmitting device.
If at least one USB interface is configured on the terminal equipment, all the configured interfaces meet the requirement that the remote control receiving equipment can be accessed to further carry out remote control on the terminal equipment, and the function that the external mobile equipment can be connected to charge the mobile equipment is also met. When any one USB interface is externally connected with one device, the terminal device can judge the current device externally connected with the USB interface, and then judges which working mode is started.
The flow of the working method of the two connection modes is shown in fig. 3:
s31, judging the current working mode of the USB interface of the terminal equipment;
s32, if the current working mode of the USB interface is a charging mode, charging the mobile equipment connected with the USB interface through the USB interface;
and S33, if the current working mode of the USB interface is the remote control mode, the USB interface receives the remote control signal input by the remote control receiving equipment connected with the USB interface, and inputs the remote control signal into the micro control unit of the terminal equipment for decoding, and the terminal equipment executes corresponding operation according to the decoded remote control instruction.
In step S32, if the current operating mode of the USB interface is the charging mode, the mobile device connected to the USB interface is the USB interface, and the USB interface needs to output and charge the mobile device. In a specific application process, when a function of receiving a remote control signal is required to be realized in a remote control working mode, a circuit, which is often input to a terminal device micro control unit through a USB interface, can obtain a weak remote control signal after remote transmission in a corresponding manner of reducing a resistance value, so that a purpose of increasing a remote control distance is realized. However, if the USB interface capable of implementing the remote control mode operation is simply connected to the mobile device to implement the function of charging the mobile device, the current may be too strong to cause unnecessary damage to the mobile device.
Therefore, in order to realize the functions of charging the external mobile device and receiving the remote control signal of the external remote control receiving device on the same USB interface, the USB interface needs to be improved. Namely, when the USB interface works in the charging mode, a resistor path is additionally arranged at the front end of the USB interface, namely, in a circuit between the terminal device micro-control unit and the USB interface, so that the current input to the USB interface is regulated and controlled, and the charging safety of the external mobile device is effectively protected.
Preferably, the added resistance value should meet the configuration requirement of the charging port of the external mobile device operating system.
In step S33, if the current operating mode of the USB interface is the remote control mode, the device connected to the USB interface is a remote control receiving device, and the remote control receiving device receives a remote control signal sent by a wireless signal; the remote control receiving device sends the remote control signal to a micro control unit in the terminal equipment; and the terminal equipment executes corresponding operation according to a remote control instruction obtained by decoding the remote control signal by the micro control unit.
Specifically, the remote control signal is generated by a remote control transmitting device, and the specific process of generating the remote control signal includes:
the remote control transmitting equipment reads the key value which is pressed currently;
and the remote control transmitting device modulates the key value to 2.4GHz through a built-in radio frequency transmitting chip to generate a remote control signal.
That is, any key value of the current remote control transmitting device corresponds to a corresponding remote control instruction, and after the key value pressed currently is read by the remote control transmitting device, the remote control transmitting device modulates the key value pressed currently to 2.4GHz through a built-in radio frequency transmitting chip to generate a remote control signal for the terminal device. Specifically, in the remote control transmitting device, the remote control instruction corresponding to any key value is implemented through the following operation processes:
the remote control transmitting equipment and a remote control receiving device connected with the current USB interface are paired one to one through a software program;
programming a radio frequency transmitting chip arranged in the remote control transmitting equipment, giving a remote control instruction corresponding to a key value of a key on the remote control transmitting equipment, and storing the corresponding relation between the remote control instruction and the key value into a micro control unit of the terminal equipment.
Through the operation method, any key on the remote control transmitting equipment is manually set with a corresponding remote control instruction corresponding to the control information of the terminal equipment, if the current key is pressed, the key value of the key is modulated to 2.4GHz to generate a remote control signal, the remote control information is transmitted and input to a micro control unit of the terminal equipment through a USB interface after being received by the remote control receiving equipment, the micro control unit decodes the received remote control information according to the corresponding relation between the control instruction and the key value stored inside, namely, the key value with the modulation frequency of 2.4GHz is converted into the remote control instruction corresponding to the key value, and the terminal equipment identifies the remote control instruction and executes the operation required by the remote control instruction.
In particular, a simple example of an application is an intelligent desk lamp, which comprises a USB interface. The outside of the USB interface can be externally connected with a mobile phone, so that the function of charging the mobile phone connected with the USB interface by the intelligent desk lamp is realized, namely a charging working mode; in addition, the USB interface can also be externally connected with a remote control receiving device, and the USB interface receives remote control information sent by the remote control receiving device, transmits the remote control information to a micro control unit of the desk lamp for decoding, acquires a remote control instruction and executes corresponding operation. In this specific operation example, if it is assumed that there are only 3 keys on the remote control transmitting device paired with the remote control receiving device, the key values of the 3 keys are: "1", "2" and "3". By programming a built-in radio frequency transmitting chip in the remote control transmitting device, the remote control instruction corresponding to the key value '1' is 'off', the remote control instruction corresponding to the key value '2' is 'on', the remote control instruction corresponding to the key value '3' is 'light intensity change', and meanwhile, the corresponding relation between the remote control instruction and the key value is manually stored in a micro control unit of the terminal equipment. When a key corresponding to the key value "1" is pressed, the remote control transmitting device modulates the key value "1" to 2.4GHz to generate a remote control signal, and transmits the remote control signal to the remote control receiving device in a wireless radio frequency transmission mode, after the remote control receiving device receives the remote control signal, the remote control signal is transmitted to a micro control unit of the desk lamp through a USB interface, the micro control unit decodes the remote control signal according to the corresponding relation between the key value stored in the micro control unit and a control instruction, decodes the key value "1" into a corresponding remote control instruction "off", and executes the operation of turning off the lamp.
Namely, according to the working process of the remote control mode, the remote control transmitting device and the remote control receiving device can be applied to different terminal equipment, so that the utilization rate of resources is improved, and the universality is high.
Preferably, the terminal device may determine whether an additional resistor path is needed at one end of the USB interface located at the terminal device by determining a specific operating mode of the current USB interface. If the current working mode of the USB interface is judged to be the remote control mode, a resistance channel additionally arranged on the current USB interface is closed; and when the current working mode of the USB interface is judged to be the charging mode, opening a resistance channel additionally arranged on the current USB.

the remote control module is used for connecting the USB interface of the terminal equipment with the remote control receiving equipment and receiving a remote control signal sent by a wireless signal by the remote control receiving equipment; the remote control receiving equipment sends the remote control signal to a micro control unit in the terminal equipment; the terminal equipment executes corresponding operation according to an instruction obtained by the micro control unit decoding the remote control signal;
and the charging module is used for connecting the USB interface of the terminal equipment with the mobile equipment and charging the mobile equipment, wherein the USB interface is the same interface as the interface in the remote control mode, and the USB interface is positioned at one end of the terminal equipment and is additionally provided with a resistor channel.
Preferably, the above system further comprises a remote control transmitting device, and the remote control module 41 comprises:
a reading sub-module 411, configured to enable the remote transmitting device to read a currently pressed key value;
and the modulation submodule 412 is configured to enable the remote control transmitting device to modulate the key value to 2.4GHz through a built-in radio frequency transmitting chip, so as to generate a remote control signal.
Preferably, the reading sub-module 411 includes:
a pairing submodule 4111, configured to pair the remote control transmitting device and the remote control receiving device in a one-to-one manner through software;
the instruction generating sub-module 4112 is configured to program a radio frequency transmitting chip built in the remote control transmitting device, assign a remote control instruction corresponding to a key value of a key on the remote control transmitting device, and store a correspondence between the remote control instruction and the key value in a micro control unit of the terminal device.
Preferably, the charging module is added with a resistor which conforms to the charging port configuration of the mobile device operating system.
Preferably, the system further comprises a judging module 43:
and the judging module is used for enabling the terminal equipment to judge the current USB interface using module, if the current using module is the remote control module, the resistance channel additionally arranged on the current USB interface is closed, otherwise, the resistance channel is opened.
From the above description, it can be seen that, through the implementation technology of the present invention, the same USB interface on the terminal device can not only realize the function of charging the mobile device, but also realize the function of remotely controlling the terminal device through the external remote control receiving device in cooperation with the remote control transmitting device.
