Description

Technical Field

[0001] The present invention relates to the technical field of television control, and more specifically, to a television control system based on the Internet of Things. Background Art

[0002] With the rapid development of science and technology, the Internet of Things technology has penetrated into every corner of people's lives. Among them, the rise and popularization of smart home devices is a clear sign of this technological wave. Smart homes use the Internet of Things technology to achieve the interconnection of home devices and provide users with a more convenient and intelligent home environment. In this context, the intelligent development of televisions, as the central device for home entertainment and information acquisition, is particularly noteworthy.

[0003] Traditional TV control methods, such as using physical buttons or infrared remote controls, are intuitive but inconvenient. Physical remote controls are easy to lose, and the TV's operating interface is often complex, making it difficult for the elderly and children who are not familiar with electronic devices to use. In addition, as TV functions continue to increase, the number of buttons on traditional remote controls has also increased, further complicating the operation.

[0004] In order to simplify the operation, remote control methods have emerged, allowing users to control the TV through mobile devices such as smartphones. However, existing remote control applications are often designed too complicated, with the interface full of various function buttons and complex combination operations. Although this design provides rich functions, it also sacrifices ease of use. Even young people who are familiar with electronic devices need to spend time figuring out how to use these applications, and it is even more difficult for the elderly and children. When using these applications, they often make accidental touches, causing the TV status to change unexpectedly, seriously affecting the user experience.

[0005] Therefore, although remote control has brought more possibilities to smart TVs, its usability and user experience still need to be improved. Especially under the current trend of interconnection of smart home devices, how to design a smart TV control solution that is both feature-rich and easy to operate has become an urgent problem to be solved. This requires in-depth analysis of user habits and combining the latest interactive design concepts to create a smart TV control experience that truly meets user needs.

[0006] Therefore, in order to solve the above technical problems, the present invention proposes a television control system based on the Internet of Things. Summary of the invention

[0007] In view of the deficiencies in the prior art, an object of the present invention is to provide a television control system based on the Internet of Things.

[0008] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a television control system based on the Internet of Things, comprising a mobile terminal and a television terminal, which are connected via a connection module;

[0009] The adjustment module is set in the mobile terminal. The adjustment module includes two input methods, which can be selected on the page to enter the corresponding page. Both input methods are used to generate control instructions according to the user's operation; there is an entrance to the adjustment module in the mobile terminal, which is respectively provided with handwriting and micro-motion adjustment methods;

[0010] The control module is arranged in the TV terminal and is used to control the TV according to the control instructions;

[0011] The connection module includes a pairing unit and a transmission unit, and the pairing unit is used to establish a connection between the mobile terminal and the TV terminal;

[0012] The transmission unit includes a transceiver unit arranged in the mobile terminal and the TV terminal;

[0013] The transceiver unit uses a data transmission module and can transmit through a Wi-Fi network. The Wi-Fi modules installed in mobile phones and TVs at the factory can realize data transmission between the two.

[0014] Furthermore, one of the input methods of the adjustment module is realized through a handwriting input unit. In this case, the mobile terminal is required to have a touch screen recognition function. The handwriting input unit contains an image recognition program. The image recognition program is used to identify the content input by the user, and after determining whether the content meets the requirements, prompt it and send it to the TV end through the transmission unit.

[0015] Furthermore, the user input content can be customized by inputting the corresponding symbol and the corresponding operation in the handwriting input unit in advance, and then drawing the symbol in the handwriting input unit can complete the corresponding operation;

[0016] It is more flexible, easier to use, and has a lower usage threshold. After completing a command operation, the mobile terminal will vibrate to prompt, and the vibration function is mainly realized by the vibration motor in the mobile terminal.

[0017] Furthermore, another input method of the adjustment module is realized through the micro-motion control unit. In this case, the mobile terminal needs to have a three-axis gyroscope function. The three-axis gyroscope is composed of three independent gyroscopes, which measure the angular velocity of the object around the X-axis, Y-axis and Z-axis respectively. It works based on the principle of conservation of angular momentum. When the three-axis gyroscope is subjected to an external torque, its rotation axis will change. By measuring this change, the angular velocity and direction of rotation of the object can be calculated. It is a common device in the mobile terminal and will not be described in detail in this article. The micro-motion control unit includes a displacement recognition program for monitoring the deflection of the three-axis gyroscope in the mobile terminal. The displacement recognition program monitors the amount of angular displacement of each axis according to the gyroscope, and converts the detected movement trajectory into a control signal and sends it to the TV terminal through the transmission unit;

[0018] Among them, the mobile terminal will vibrate to prompt after completing a command operation. The vibration function is mainly realized by the vibration motor in the mobile terminal.

[0019] Furthermore, the micro-motion control unit has the function of adjusting the recognition sensitivity of the three-axis gyroscope in each direction;

[0020] Prevent accidental touches when they are not necessary, improve the user experience, and avoid judging irrelevant or unintentional shaking as meaningful operations.

[0021] Furthermore, the displacement identification program will only identify the amount of angular displacement of the three-axis gyroscope once within 1 second;

[0022] In order to avoid repeated adjustment instructions due to accidental touches, each identical instruction will only be triggered once within 1S.

[0023] Furthermore, the control signal is a default value set at the factory, and a function of modifying the movement trajectory and the corresponding control signal is provided in the micro-motion control unit.

[0024] Furthermore, the control module is used to operate the TV end according to the received instructions. If the received instructions cannot be recognized, the control module controls the TV end to broadcast an error prompt, prompting the user that the operation cannot find the corresponding instruction.

[0025] Further, according to any one of the television control systems based on the Internet of Things, the pairing unit includes the following pairing method:

[0026] a: The mobile terminal and the TV terminal are connected to the same local area network;

[0027] b: Both the mobile terminal and the TV terminal obtain an IP address (Internet Protocol address) from the router through the DHCP protocol to identify themselves;

[0028] c: The TV generates a random digital pairing code and displays it, and then broadcasts the digital pairing code in the LAN through the LAN service discovery protocol mDNS;

[0029] d: The user enters the digital pairing code on the mobile terminal for verification, and then sends an HTTP request containing the pairing code information to the TV terminal IP address (Internet Protocol address);

[0030] e: The TV receives this request and parses it to obtain the pairing code information. If they are consistent, the authentication is successful. The TV stores the information of the mobile device and returns a response containing confirmation of successful pairing. After the response is received by the mobile device, the mobile device and the TV establish a long connection. The mobile device can start sending control commands to the TV until the user actively chooses to disconnect. This long connection uses WebSocket (a full-duplex communication protocol) based on TCP (Transmission Control Protocol) to establish a full-duplex connection between the TV and the mobile smart device to ensure that the commands can be accurately transmitted.

[0031] If the mobile terminal has already established a connection with the TV terminal, there is no need to verify the digital pairing code.

[0032] Furthermore, the transmission unit transmits signals through transceiver units arranged in the mobile terminal and the TV terminal. After the mobile terminal generates a control instruction, it sends the instruction to the TV terminal through the HTTP protocol. At the same time, the TV terminal also synchronizes its own state to the mobile terminal.

[0033] When in sleep or shutdown mode, the mobile terminal will be notified of the current status of the TV.

[0034] Compared with the prior art, the present invention has the following beneficial effects:

[0035] 1. In the present invention, the handwriting input unit provided in the mobile terminal allows the user to complete the corresponding operation by simply drawing a simple picture on the page, which is very friendly to some elderly people with poor eyesight. In addition, some symbols can be customized according to the user's usage habits. A combined operation can be achieved through these symbols. The young people at home or the corresponding personnel can customize it in advance, which is convenient for the elderly and children to operate, thereby solving the problem that the current wireless operation equipment has high requirements for users and is difficult to use.

[0036] 2. In the present invention, the micro-motion control unit arranged in the mobile terminal allows the user to complete the operation only by deflecting the position of the mobile terminal. This is of great help to the elderly and children who are not accustomed to using smart devices, or the elderly with poor eyesight. There is no need to click or draw, and the desired operation can be completed through micro-motion, which is more convenient and easy to use. DETAILED DESCRIPTION

[0037] The present invention provides a television control system based on the Internet of Things, including a mobile terminal and a television terminal, which are connected via a connection module;

[0038] This mobile terminal is an application that can be installed on mobile devices such as mobile phones. On the mobile terminal, users are allowed to use handwriting control and micro-control to operate the TV to achieve functions such as changing channels, adjusting volume, calling out menus, etc. The solution is applicable to smart TVs and mobile smart devices using the Android operating system (Android operating system).

[0039] The adjustment module is arranged in the mobile terminal. The adjustment module includes two input modes, both of which are used to generate control instructions according to the user's operation. There is an entrance to the adjustment module in the mobile terminal, which is respectively provided with two adjustment modes, namely handwriting and micro-motion, and can be selected on the page to enter the corresponding page;

[0040] The control module is arranged in the TV terminal and is used to control the TV according to the control instructions;

[0041] The connection module includes a pairing unit and a transmission unit, and the pairing unit is used to establish a connection between the mobile terminal and the TV terminal;

[0042] The transmission unit includes a transceiver unit arranged in the mobile terminal and the television terminal;

[0043] The transceiver unit uses a data transmission module, which can be transmitted through the Wi-Fi network (wireless network communication technology, hereinafter referred to as Wi-Fi). Through the Wi-Fi module installed in the mobile phone and TV at the factory, data transmission between the two can be achieved;

[0044] When controlling the TV through the mobile terminal, you need to establish a connection between the TV and the mobile terminal. First, you need to pair the mobile terminal and the TV.

[0045] Here is how to pair your mobile device with your TV:

[0046] a: The mobile terminal and the TV terminal are connected to the same local area network;

[0047] b: Both the mobile terminal and the TV terminal obtain an IP address (Internet Protocol address) from the router through the DHCP protocol (Dynamic Host Configuration Protocol, hereinafter referred to as DHCP protocol) to identify themselves;

[0048] c: The TV generates a random digital pairing code and displays it, and then broadcasts the digital pairing code in the LAN through the LAN service discovery protocol mDNS (Multicast DNS, a network protocol that is mainly used to enable hosts in the LAN to discover and communicate with each other without a traditional DNS server, hereinafter referred to as mDNS);

[0049] d: The user enters the digital pairing code on the mobile terminal for verification, and then sends an HTTP (Hypertext Transfer Protocol, hereinafter referred to as HTTP protocol) request containing the pairing code information to the TV terminal IP address (Internet Protocol address);

[0050] e: The TV receives the request and parses it to obtain the pairing code information. If they match, the authentication is successful. The TV stores the mobile device information and returns a response that confirms the pairing success.

[0051] After the response is received by the mobile device, a long connection is established between the mobile device and the TV, and the mobile device can start sending control commands to the TV until the user actively chooses to disconnect. The long connection uses WebSocket (a full-duplex communication protocol) based on TCP (Transmission Control Protocol) to establish a full-duplex connection between the TV and the mobile smart device to ensure that the commands can be accurately transmitted;

[0052] If the mobile terminal has established a connection with the TV terminal, there is no need to verify the digital pairing code;

[0053] The transmission unit transmits signals through the transceiver units set in the mobile terminal and the TV terminal. After the mobile terminal generates a control command, it sends the command to the TV terminal through the HTTP protocol. At the same time, the TV terminal will also synchronize its own status to the mobile terminal. For example, when the TV terminal is in sleep or shutdown state, the mobile terminal is prompted with the status of the TV terminal at this time.

[0054] The specific instructions are as follows:

[0055] After the mobile smart device obtains the instruction content through identification and analysis, it sends the instruction to the TV through the HTTP protocol. To this end, first of all, both need to be connected to the same local area network, in the actual environment, that is, connected to the same Wi-Fi network. Then, both obtain an IP address (Internet Protocol address) from the router through the DHCP protocol to identify themselves. After the mobile smart device determines the instruction to control the TV through identification and analysis, it sends a POST (POST is a request method in the HTTP protocol, mainly used to submit data to the server) request to the TV. The HTTP server on the TV receives this request and parses it, obtains the instruction carried by the request and performs the operation.

[0056] The above description is how the mobile device communicates with the TV under normal use. For the first pairing, in order to ensure security and pairing accuracy, when pairing for the first time, the TV will give a randomly generated digital pairing code and start the local area network service discovery protocol mDNS to broadcast its services (including its pairing code) in the local area network; at the same time, the mobile terminal also uses mDNS to discover the TV service in the local area network, and the user enters the pairing code in the mobile terminal window for authentication. If the TV address is found, the mobile device will send an HTTP request containing the pairing code information to its IP address (Internet Protocol address). The TV receives this request and parses it to obtain the pairing code information. If it is consistent, the authentication is successful. The TV stores the information of the mobile device and returns a response containing confirmation of successful pairing. After the response is received by the mobile device, the mobile device and the TV establish a long connection. The mobile device can start sending control commands to the TV until the user actively chooses to disconnect. The long connection uses WebSocket (a full-duplex communication protocol) based on TCP (Transmission Control Protocol) to establish a full-duplex connection between the TV and the mobile smart device to ensure that the command can be accurately transmitted.

[0057] It should be noted that one of the input modes of the adjustment module is implemented through a handwriting input unit. In this case, the mobile terminal needs to have a touch screen recognition function. The handwriting input unit contains an image recognition program. The image recognition program is used to recognize the content input by the user, and after determining whether the content meets the requirements, it prompts and sends it to the TV terminal through the transmission unit;

[0058] It is worth noting that the user input content can be customized, by inputting the corresponding symbol and corresponding operation in the handwriting input unit in advance, and then drawing the symbol in the handwriting input unit to complete the corresponding operation;

[0059] This is more flexible, easier to use, and has a lower threshold for use. After completing a command operation, the mobile terminal will vibrate to prompt, and the vibration function is mainly realized by the vibration motor in the mobile terminal;

[0060] The handwriting input unit set in the mobile terminal allows users to complete the corresponding operation by simply drawing a simple picture on the page, which is very friendly to some elderly people with poor eyesight. In addition, some symbols can be customized according to the user's usage habits. Through these symbols, a combined operation can be achieved, which can be customized in advance by the young people or relevant personnel in the family, making it easier for the elderly and children to operate.

[0061] It should be noted that another input method of the adjustment module is realized through the micro-control unit, in which case the mobile terminal needs to have a three-axis gyroscope function;

[0062] The three-axis gyroscope is composed of three independent gyroscopes, which measure the angular velocity of an object around the X-axis, Y-axis, and Z-axis respectively. It works based on the principle of conservation of angular momentum. When the three-axis gyroscope is subjected to external torque, its rotation axis will change. By measuring this change, the angular velocity and direction of the object's rotation can be calculated. It is a common device in mobile terminals and will not be described in detail in this article.

[0063] The micro-motion control unit includes a displacement recognition program for monitoring the deflection of the three-axis gyroscope in the mobile terminal. The displacement recognition program monitors the amount of angular displacement of each axis according to the gyroscope, and converts the detected movement trajectory into a control signal and sends it to the TV terminal through the transmission unit;

[0064] Among them, after completing a command operation, the mobile terminal will vibrate to prompt, and the vibration function is mainly realized by the vibration motor in the mobile terminal;

[0065] It is worth noting that the micro-control unit has the function of adjusting the recognition sensitivity of the three-axis gyroscope in each direction;

[0066] Prevent accidental touches when they are not needed, improve the user experience, and avoid judging irrelevant or unintentional shaking as meaningful operations;

[0067] The displacement recognition program will only recognize the angular displacement of the three-axis gyroscope once within 1 second. In order to avoid repeated adjustment instructions due to false triggering, each identical instruction will only be triggered once within 1 second.

[0068] The control signal is the default value set by the factory. The function of modifying the movement trajectory and the corresponding control signal is set in the micro-motion control unit, so as to adjust the control command according to the actual situation of the user;

[0069] The control module is used to operate the TV terminal according to the received instructions. If the received instructions cannot be recognized, the control module controls the TV terminal to broadcast an error prompt, prompting the user that the operation cannot find the corresponding instruction;

[0070] Through the above, the micro-motion control unit set in the mobile terminal allows the user to complete the operation only by deflecting the position of the mobile terminal. It is of great help to the elderly and children who are not accustomed to using smart devices, or the elderly with poor eyesight. There is no need to click and draw, and the desired operation can be completed through micro-motion, which is more convenient and easy to use.

[0071] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any form. Any ordinary technician in the industry can smoothly implement the present invention as described above. However, any equivalent changes, modifications and evolutions made by technicians familiar with the profession without departing from the scope of the technical solution of the present invention using the technical content disclosed above are all equivalent embodiments of the present invention. At the same time, any equivalent changes, modifications and evolutions made to the above embodiments based on the essential technology of the present invention are still within the protection scope of the technical solution of the present invention.
