It is emphasized that a device server is a server that is specific to a particular brand of smart device and is used to remotely control the particular brand of smart device.
The implementation of the above process needs to depend on a home wireless network, and a weak or unstable signal phenomenon often occurs in home WIFI, such as: the router is installed in the living room, and the WIFI signal in the bedroom will be unstable, and the user uses speech controller will appear the problem that control command delays in the bedroom.
Current mobile networks, particularly fifth generation mobile communication networks, have data transmission rates much higher than previous cellular networks and also have low network delays. In the future, the 5G network will not only provide services for mobile phones, but also become a general home and office network provider, and compete with wired network providers.
By setting the personal hotspot of the mobile terminal 5G mobile network, other devices, such as: and the controller can access the network resource by using the hotspot network.
On the other hand, the transmission of the control instruction has low dependence on the network speed; the control command may be set and sent through the mobile terminal APP, for example: the more popular bluetooth lamp at present, bluetooth kettle etc. are all through removing end APP and bluetooth transmission control instruction.
Fig. 3, fig. 4, and fig. 5 correspond to block diagrams of the controller, the mobile terminal, and the smart device, respectively;
the wireless communication module generally refers to a WIFI module and a Bluetooth module; bluetooth is a short-range wireless transmission technology, and WIFI accesses an external network through a router.
The system comprises a trigger module, namely a wake-up module, for detecting wake-up words, wherein the current intelligent voice equipment is provided with the wake-up module in most cases;
a voice instruction acquisition module, namely a microphone array, is usually 2 to 6 microphones in different sizes, and the microphone array usually uses a noise reduction technology to shield background noise and amplify human voice to improve the accuracy of voice recognition; some microphone arrays also have a sound source localization function, and can determine the approximate position of a speaker according to human voice, so as to shield sounds in other directions.
APP: the meaning of Application software is short for english Application, and current APPs mostly refer to third-party Application programs of smart phones.
The controller APP corresponds to a controller for configuring the controller with a network and setting other parameters related to the controller.
Smart machine APP corresponds with smart machine, and under the general condition, the smart machine APP of a brand/producer can correspond a plurality of smart machine of this brand, and smart machine APP can bind a plurality of smart machine simultaneously, carries out remote control to a plurality of smart machine.
The 5G communication module is a communication module dedicated to receiving 5G mobile network signals, such as: the 5G millimeter wave antenna module is simultaneously provided with a power amplifier and an antenna array for signal enhancement. Since the 5G mobile communication uses high frequency resources that have not been developed and utilized, the mobile terminal must use the 5G communication module instead of the current 4G communication module to receive signals of the high frequency resources.
Smart devices can be roughly divided into large devices and small devices, and large devices, such as smart air conditioners, are generally equipped with both WIFI and bluetooth, and small devices, such as: the bluetooth lamp generally only has a bluetooth communication module. For the Bluetooth lamp, the control instruction can be transmitted through a BLE4.0/5.0 protocol; for the intelligent air conditioner, the control instruction can be transmitted through Bluetooth or through a hotspot network.
Currently, most of the bluetooth modules are bluetooth 4.0 and 4.2, and the bluetooth 5.0 module adopts a BLE5.0 protocol, so that the transmission speed is greatly improved. The Bluetooth 5.0 module can support a BLE5.0 protocol and also can support a BLE4.0 protocol. When the Bluetooth 5.0 module is in communication connection with the Bluetooth 4.0 and 4.2 modules, a BLE4.0 protocol is adopted; and when the Bluetooth 5.0 module is in communication connection with another Bluetooth 5.0 module, the BLE5.0 protocol is adopted.
