Description

Technical Field

[0001] The present invention relates to the field of wireless control technology, and in particular to a wireless indication system and a control method. Background Art

[0002] With the continuous advancement of technology, wireless pointing tools are also developing in a variety of ways. Laser pointers can provide precise instructions at a distance, while presentation mice can provide instructions while controlling the presentation content, which improves the interactivity of teaching. In the field of education, wireless pointing tools have become a must-have tool for many teachers in classroom teaching. They are not only used to indicate key information on the big screen, but also help students better understand and remember the teaching content.

[0003] However, although wireless pointing tools are already quite common in teaching, they still have some obvious drawbacks. When teachers are sitting and giving lectures, they may feel uncomfortable using laser pointers due to the limitations of their body posture. Maintaining this posture for a long time may cause muscle fatigue and discomfort. The pointing range of laser pointers is usually limited. If the classroom is too large or the screen is too high, the pointing effect of laser pointers may be greatly reduced. Summary of the invention

[0090] The embodiment of the present invention further provides a control method of a wireless indication tool, which is applied to the wireless indication system, and includes:

[0091] Powering on the receiver and placing the receiver in a pairing state;

[0092] and searching for a matching device to be matched within a preset time threshold, and obtaining a pairing signal of the device to be matched; the device to be matched includes a presentation pen or a presentation mouse;

[0093] The device identification is acquired based on the pairing signal, and pairing is performed based on the device identification to establish a connection between the receiver and the device to be matched.

[0094] Please refer to Figure 7 , Figure 7A schematic flow chart of a control method for a wireless indicating tool provided by an embodiment of the present invention.

[0095] In this embodiment, the receiver is powered on, that is, the receiver is plugged into the terminal device, and then it starts searching for nearby devices. Pairing can be accepted within the next preset time (the default setting is 1 minute) until the pairing is completed or the countdown ends, and the pairing mode ends; the presentation device, that is, the presentation mouse or presentation pen, turns on the switch, presses the pairing button, and then starts searching for nearby devices. The next 20 seconds are in pairing mode until the pairing is completed or the countdown ends, and the pairing mode ends; when the presentation device and the receiver both enter the pairing mode, they will search for devices with each other. When the transmitter searches for the receiver, it will immediately send a pairing request to the receiver and reduce its own transmission power; when the receiver in pairing mode receives the pairing request data from the transmitter, it will then reduce its own transmission power and start parsing and verifying the data; if the receiver verifies the data successfully, it will reply to the presentation device that the pairing process can be entered. If the data verification fails, the pairing mode ends;

[0096] In this embodiment, because both the presentation device and the receiving end will reduce their own transmission power in the above process, the presentation device needs to be close to the receiver. It is precisely because of this unique pairing method that a unique and non-replicable connection is established between the two, avoiding the risk of information leakage;

[0097] In this embodiment, after receiving the pairing data allowing entry, the presentation device starts to send its own device information in a directional manner;

[0098] In this embodiment, the receiver receives the device information of the presentation device and verifies the authenticity of the device. If the verification fails, the message is discarded without any response. After the verification succeeds, the receiver interprets the data as a valid device and sends its own device information to the presentation device in a directional manner.

[0099] In this embodiment, after receiving the receiver device information, the speaker device verifies the authenticity of the device. If the verification fails, the pairing is terminated. If the verification succeeds, the speaker device verifies the receiver message successfully and sends a pairing confirmation message to the receiver. If the sending is successful, the receiver address and other information are saved, and the sending end completes the pairing.

[0100] In this embodiment, the receiver receives the pairing confirmation message and determines whether pairing has been established with the type of presentation device. If the same type of sending end device information is saved in the receiver, this pairing will overwrite the device information of the previous same type of presentation device (maintaining the principle that only one presentation device of the same type can be saved to avoid confusion), and the receiver pairing is completed.

[0101] In this embodiment, when the presentation pen is paired with the receiver, the presentation pen receiver is powered on, that is, the switch is turned on, and the pairing key is pressed, that is, the function switch key and the page down key are pressed. At this time, the indicator light of the presentation pen lights up green and flashes quickly, indicating that it enters the pairing state; bring the presentation pen close to the receiver, the green light flashes slowly and then goes out, indicating that the pairing is successful. If the indicator light stops after 20 seconds, it means that the pairing has failed.

[0102] In this embodiment, when the presentation mouse is paired with the receiver, the presentation mouse is powered on and the pairing key is pressed, that is, the function switch key and the screenshot function key are pressed at the same time. At this time, the indicator light turns blue and flashes quickly, indicating that the pairing state has been entered; the presentation mouse is brought close to the receiver, the blue light flashes slowly and then goes out, indicating that the pairing is successful. If the indicator light stops after 20 seconds, it means that the pairing has failed.

[0103] In this embodiment, after the connection between the receiver and the device to be matched is established, the method further includes: switching the connection of the presentation device based on the device identifier, specifically:

[0104] Acquire a current device instruction based on the receiver, and parse the current device instruction to acquire a device identifier;

[0105] It is determined whether the device identifier is consistent with the current matching identifier. If they are consistent, the current device instruction is processed based on the current matching identifier. Otherwise, the device identifier is saved and the current device instruction is processed based on the instruction identifier.

[0106] Please refer to Figure 8 , Figure 8 A schematic diagram of a speech device switching process improved in an embodiment of the present invention.

[0107] In this embodiment, the sending end (speech pen or speech mouse) generates instructions by pressing keys; the sending end checks whether the device identification of the receiving end (receiver), that is, flag information, is currently saved. If the flag information is saved, it will be packaged with the key instruction and sent to the receiving end; if the sending end does not save the flag information of the receiving end, this will be the first time for the sending end to communicate with the receiving end. At this time, the sending end will package the request flag message with the key instruction information and send it to the receiving end;

[0108] In this embodiment, the receiver determines whether it has a saved device identification, where the device identification is flag information, which indicates a flag that is currently working with the sender. When the sender and the receiver have not communicated for more than 500ms, the flag of the receiver will be cleared, which also means that different sender devices can establish a connection with the receiver.

[0109] In this embodiment, when the receiver has flag information, the sending device communicating with the receiver cannot be replaced. At this time, it is only necessary to determine whether the two flags are consistent, that is, to determine whether the device identifier is consistent with the current matching identifier. If they are consistent, the key message can be processed, otherwise the key message will be discarded.

[0110] In this embodiment, when the receiver has no flag information, the receiver has not yet established a connection with any sender. In this case, the key message can be processed, and the receiver will generate a new flag information and send it back to the sender.

[0111] In this embodiment, when the sending end receives the flag message, it only needs to save it and generate a timer. If no data is received or no key message is generated within 500ms, the flag message can be cleared.

[0112] In this embodiment, if the receiver does not receive a message from the sender including the flag within 500ms of generating the flag information, the receiver releases the flag information.

[0113] In this embodiment, when the first binding key data interaction has not occurred between the sender and the receiver, the intelligent judgment process ensures that the receiver can also process the first key instruction sent by the sender, thereby ensuring the timeliness of the receiver's response; it is also because the sender and the receiver generate and destroy flag information in an orderly manner that the orderliness of alternating use between different sending devices is ensured.

[0114] In this embodiment, after establishing a connection between the receiver and the device to be matched, a device instruction of the device to be matched is received, and a screen projection operation is performed based on the device instruction.

[0115] In this embodiment, a connection is established between the receiver and the device to be matched. If the presentation device connected to the receiver is a presentation mouse, the terminal device is controlled to perform screen projection through the one-touch screen projection key of the presentation mouse.

[0116] Please refer to Fig. 9 , Fig. 9 A schematic diagram of a screen projection operation process provided in an embodiment of the present invention.

[0117] In this embodiment, the speech pen mouse control software monitors the USB data of the speech mouse connected to the computer in real time. When the speech mouse presses the "wireless speech mouse screen projection button", the speech pen mouse control software receives the one-key screen projection command and first determines whether the "wireless screen projection transmitter" is in the startup state. If it is started, a one-key screen projection command is sent to the "wireless screen projection transmitter" (here, interprocess communication (IPC) is used); if it is not started, first determine whether the system has installed the "wireless screen projection transmitter"; if it is already installed, start the "wireless screen projection transmitter" and pop up the corresponding prompt; if it is not installed, a corresponding prompt pops up to prompt the user to install the "wireless screen projection transmitter" and then exit.

[0118] In this embodiment, after receiving the one-key screen projection command, the "wireless screen projection transmitter" determines whether it is connected to the "wireless screen projection receiver"; if it is in the connected state, it determines whether it is currently in the screen projection state; the connection state refers to whether the "wireless screen projection transmitter" has established a connection with the "wireless screen projection receiver"; if it is in the non-screen projection state, the "wireless screen projection transmitter" will initiate screen projection to the "wireless screen projection receiver" at this time; if it is in the screen projection state, the "wireless screen projection transmitter" will initiate the stop of screen projection to the "wireless screen projection receiver";

[0119] When the connection status is not connected, the "Wireless Screen Projection Transmitter" cannot perform the screen projection operation, so a list of "Wireless Screen Projection Receiver" devices in the local area network pops up, and the user selects the target "Wireless Screen Projection Receiver" to be projected; after the user selects a "Wireless Screen Projection Receiver", the "Wireless Screen Projection Transmitter" tries to connect to the "Wireless Screen Projection Receiver" device selected by the user. After the connection is successful, the "Wireless Screen Projection Transmitter" initiates screen projection to the "Wireless Screen Projection Receiver". Regardless of whether the connection is successful or the projection is successful, the "Wireless Screen Projection Transmitter" will send the status to the "Presentation Pen and Mouse Control Software" for prompts.

[0120] In this embodiment, a receiver is used to connect the presentation pen and presentation mouse to achieve seamless switching between the presentation pen and presentation mouse, and the user can change the control tool at any time during the presentation. The receiver can intelligently identify and process commands from different devices based on the device identification, improving the efficiency of switching between tools. And through fast and intelligent pairing and command parsing, users can maintain efficiency in the presentation and reduce time delays and usage troubles caused by switching tools. Whether turning pages or performing other functions, the receiver can respond quickly to improve the fluency of the presentation.
