Problems solved by technology

Cloud services have the following disadvantages: 1. User data is stored in the cloud server, which is easy to be hacked or leaked by the staff, and the security is poor; 2. The cloud server is interrupted by regular and unpredictable factors, and the stability is poor; 3. The display terminal is stuck or even has no picture caused by network delays and interruptions; 4. The cost of long-term rental cloud services is high
However, the short-range wireless communication module first established in this patent is only used to transmit the key information to establish another communication connection, and fails to make full use of the first established short-range wireless communication connection.

Embodiment 1

[0055] see figure 1 , a multi-protocol handheld terminal control method for display terminals, comprising the following steps:

[0056] According to the hardware configuration of the handheld terminal (mobile phone, tablet) and the display terminal, confirm the first wireless communication protocol, and the first wireless communication protocol is used to transmit the control command of the handheld terminal to the display terminal.

[0057] Since Bluetooth is a standard configuration of handheld terminals and display terminals, and is suitable for transmitting control commands with a small amount of data, it is generally confirmed that Bluetooth is the first wireless communication protocol. When both the display terminal and the handheld terminal support wireless communication protocols such as NFC, NFC may also be selected as the first wireless communication protocol.

[0058] The control commands include device control commands and image material control commands. The dev...

Embodiment 2

[0064] Two terminals that establish a Bluetooth connection can freely view the service information and characteristic value information of the other Bluetooth module, and obtain some terminal information by reading the readable characteristic value, and try to write data to the writable characteristic value. Therefore, it is necessary to restrict the objects connected by the Bluetooth of the display terminal to ensure the security of the Bluetooth communication. Existing Bluetooth connections can optionally be set with a pairing code to limit who the Bluetooth connects to. When pairing is not set, the Bluetooth connection is directly established between terminals. If pairing is set, the user will be asked whether to pair through a pop-up window, and then the user will manually enter the pairing code for pairing, and the Bluetooth connection will be established after the pairing is successful. However, the pop-up window is easy to be intercepted, and there are still certain se...

Embodiment 3

[0071] Further, a user password is also set in the security verification mechanism. In the initial state, no user password is set by default. After the user sets or modifies the user password on the handheld terminal, the handheld terminal will send a verification code to the display terminal (if the user password is set for the first time, the verification code at this time is the first verification code. If the password is changed, Then the verification code at this time is the second verification code) and the user password after setting or modification, and the display terminal saves the user password after the verification is successful.

[0072] In this embodiment, a multi-protocol method for controlling a display terminal by a handheld terminal according to the present invention is presented on the handheld terminal in the form of an APP. The user sets the user password through the APP on the handheld terminal A and informs the display terminal B of the user password. ...

Abstract

The invention relates to a method for controlling a display terminal by a multi-protocol handheld terminal, wherein the method comprises the following steps: confirming a first wireless communicationprotocol according to hardware configuration of the handheld terminal and the display terminal, wherein the first wireless communication protocol is used for transmitting a control command of the handheld terminal to the display terminal; confirming a second wireless communication protocol; enabling the handheld terminal to transmit image data to the display terminal through the second wireless communication protocol; and if the first wireless communication protocol is different from the second wireless communication protocol, enabling the handheld terminal to transmit configuration information required by pairing connection of the second wireless communication protocol to the display terminal through the first wireless communication protocol.

Description

technical field [0001] The invention relates to a multi-protocol hand-held terminal-to-display terminal control method and device, belonging to the field of the Internet of Things. Background technique [0002] Display terminals usually use LCD screens or ink screens as display screens. The image data formats displayed on the two screens are different, and the required data transfer rates are also different. LCD screens consume a lot of power, require high data transmission rates, and support many types of wireless communication protocols (WiFi, Bluetooth, NFC, etc.); ink screens consume little power and require low data transmission rates, and usually only support Bluetooth protocols. [0003] The prior art basically realizes the control and data transmission of the display terminal through the following two methods. One is to upload the data resources to the cloud server, and the user controls the display terminal to access the cloud through the handheld terminal to obta...
