Detailed Description
The utility model is described in detail below with reference to the figures and the specific embodiments.
Referring to fig. 1 to 3, the present invention provides an IOT intelligent keyboard, including: the keyboard IC module, the wireless connection module and the keyboard interface module. The keyboard IC module is connected with the wireless connection module and the keyboard interface module. The wireless connection module and the IOT network realize bidirectional data communication through UART communication. The wireless connection module is responsible for and IOT network, and mutual processing as master control host device, realizes two-way data communication through the UART communication between the two to realize keyboard function and BLE & WIFI function. The keyboard IC module is used as a slave device to be responsible for processing the keyboard part.
When the power-on is started, USB enumeration is detected, and if the USB slave equipment can be normally identified by the host, a wired keyboard working mode is entered. And if the host does not recognize the USB equipment, the wireless keyboard mode is switched to. After initializing the related interface, starting the timing scanning keyboard, uploading the key value obtained by scanning and the keyboard state to the instruction of the wireless connection module through the UART interface, immediately waking up the keyboard to start working, and repeating the steps. The keyboard can be quickly paired with a host in a Bluetooth mode, a wifi mode or a USB mode and the like, and is adaptive to various operating systems such as windows, Android, MacOS, and harmony OS. Under two modes of wired connection and wireless connection, the keyboard can receive instructions and information from an IOT system while having the functions of the traditional keyboard.
The user can manage the keyboard at the IOT cloud, for example, group control is carried out on the keyboard on line, the hot key function of the keyboard is reconfigured, or the keyboard is closed/opened, and the like, so that the safety of the network system is effectively guaranteed.
The wireless connection module is BLE & WIFI module, and the chip model that BLE & WIFI module adopted is OPL 1200. OPL1200 is a low-power consumption wireless SOC with excellent performance, integrates BLE5.0 and IEEE802.11b protocol stacks, and meets the wireless communication requirement of a keyboard.
The chip model of the keyboard IC module is CH 546. The embedded USB controller of CH546 and USB transceiver support USB-Device equipment mode, support USB2.0 full speed 12Mbps or low-speed 1.5Mbps, support the biggest 64 byte data package, built-in FIFO, support DMA, provide abundant interface resource simultaneously, including 1 set of asynchronous serial ports, 2 way PWM and 8 passageway electric capacity touch button, other include 1 way principal and subordinate SPI, 8 way 12 bit ADC, support voltage comparison, built-in 3 sets of timers and 1 way signal are caught, support 44 GPIO at most, satisfy the user demand of keyboard function.
Referring to fig. 4 to 6, the present invention further includes a power module, which includes: the USB power supply circuit is connected with the keyboard IC module, the lithium battery charging and detecting circuit is connected with the lithium battery and the voltage stabilizing circuit, and the voltage stabilizing circuit is connected with the keyboard IC module and the wireless connection module. Through the configuration lithium cell for the keyboard has power saving, portable characteristics, portable use.
Referring to fig. 7, the keyboard IC module is connected to a keyboard indicator light to display various operating states of the keyboard.
In summary, the keyboard IC module and the wireless connection module enable the keyboard to be quickly paired with the host computer through bluetooth, wifi or USB and the like, so as to adapt to various operating systems, and in both wired connection mode and wireless connection mode, the keyboard can receive instructions and information from the IOT system while having the functions of the traditional keyboard, thereby meeting the requirements of the current IOT network.
