All technical characteristics in the invention can be interactively combined on the premise of not conflicting with each other.
Referring to fig. 1-2, the invention discloses a WIFI intercom device based on a micro-loudspeaker platform, which comprises a plurality of intercom devices, wherein the intercom devices are identical in structure, each intercom device comprises a micro-loudspeaker platform and a cloud platform, three kinds of basic information are configured on the micro-loudspeaker platform, and the three kinds of basic information comprise WIFI information, added friends and group chat groups. And after the configuration is finished, waiting for the access of the host, if the access of the host is successful, storing the account information into the host, facilitating the server to read information from the memory space for account login, if the access of the host is unsuccessful, reading the pre-configuration information by the micro-loudspeaker platform, facilitating the server to read information from the memory space for account login, recognizing the voice received by the micro-loudspeaker platform by the server, and distributing the voice to other talkback equipment through the WIFI docking cloud platform according to the recognized information.
In the above embodiments, the intercom device includes a mobile phone, a communication device containing WIFI or CAT 1. The communication device of CAT1 is designed for the internet of things device requiring medium and low bandwidth, and is considered to be a technology for promoting the next generation cellular I0T part. The host comprises a mobile phone, a computer and terminal equipment containing NFC. The talkback equipment can talkback a plurality of other talkback equipment and also can freely match with the group members to talkback, thereby realizing a many-to-many talkback matching mode, providing convenient service for the catering industry, satisfying various catering requirements of customers in a short time, in multiple directions and by the mobilization of a plurality of persons, and saving a lot of manpower and material resources for enterprises.
Further, the basic information of the micro-loudspeaker platform configuration comprises three modes, wherein the three modes comprise direct configuration, NFC configuration, wired configuration and pre-configuration:
referring to fig. 3, before the basic information of the micro loudspeaker platform is configured, the intercom device is powered on first and starts to initialize, including the initialization of external devices such as an ADC, a key, memory management and FreeRTSO, and further, a WIFI chip is adopted for the main control of the intercom device, and the WIFI chip is provided with a 2M internal flash, so that the memory space can be managed, and the resource application is more sufficient to the maximum extent.
Referring to fig. 4, after the intercom device is powered on, through operations such as initialization and memory management, basic information for logging in a server to perform group friend function management needs to be configured, the intercom device waits whether a host of NFC is connected, and if no host of NFC is connected, the intercom device waits for wired access. If a host of the NFC is accessed, and a user logs in the micro loudspeaker platform at a mobile phone end, the host of the NFC can automatically transmit an account, a password, a friend queue, grouping information and the like of the user into the intercom device for storage, only once configuration is needed, and the information can be read from a memory space for logging in next time.
When the micro loudspeaker platform adopts the NFC configuration mode successfully, the server logs in the micro loudspeaker platform according to the configuration information, and if the configuration is unsuccessful or the connection time exceeds, the micro loudspeaker platform is replaced with a wired configuration mode, referring to fig. 5, the wired configuration mode is consistent with the NFC configuration mode, and all the accounts, passwords, friend queues, grouping information and the like of the user need to be automatically transmitted to the intercom device and stored. When the wired configuration mode is successfully configured, the server logs in the micro loudspeaker platform according to the configuration information, when the configuration is unsuccessful or the connection is waited for overtime, the wired configuration mode is replaced by the pre-configuration mode, the pre-configuration mode is a WIFI connection mode, referring to fig. 6, the information of the pre-configuration mode comprises the configuration information of the micro loudspeaker platform which is delivered from a factory and the information of the previous micro loudspeaker platform which is successfully configured, when the pre-configuration mode is successfully configured, referring to fig. 7, the server logs in the micro loudspeaker platform according to the configuration information.

The data processing stage comprises four threads, wherein the four threads comprise key events, voice data acquisition, voice coding compression uploading and voice decoding playing, and the four threads are as follows:
thread 1: and in the key event, each key of the intercom device is used as an independent thread, the state of the key is monitored in real time, when the key is pressed down, an internal system of the intercom device performs software filtering on the key to judge the state of the key, and then different functions are executed.
Power key: and long pressing for 3-5 seconds, starting/shutting down the equipment, short pressing for 1 time in the starting state, and awakening with low power consumption.
Volume +: increase the volume
Volume-: volume reduction
The talkback key-press: pressing the key to not release, starting talkback, releasing the key and finishing talkback.
Thread 2: voice data acquisition, when the button of talkbacking presses down, the ADC of WIFI chip can gather the waveform of miaow head sampling, and the WIFI chip carries out software filtering to the data of gathering.
Thread 3: and voice coding compression and uploading, wherein after the filtered data is received, the thread creates an encoder to encode and compress the data, and meanwhile, the compressed data and the client information are created to a server while being compressed, and the server distributes the data according to the instruction of the input information.
Thread 4: and voice coding and playing, namely after the equipment receives a voice packet distributed by the server, creating a decoder, decoding the data, transmitting the decoded data to an operational amplifier circuit, and playing the voice through a loudspeaker.
When the method is implemented specifically, the talkback equipment has two awakening modes including voice awakening and key awakening, the voice awakening mode is that the microphone receives a specified word to awaken the talkback equipment, the specified word such as the code or name of a specified service person can awaken the talkback equipment, and the key awakening mode is that the talkback equipment is awakened by pressing down the microphone within 1S in a short time. After the equipment is awakened, the microphone starts to collect sound, the voice is compressed into a data packet through opus and is uploaded to the server for processing, the server identifies the voice packet and distributes the voice packet to other talkback equipment through the WIFI docking cloud platform according to the identified information, the other talkback equipment receives the information through the loudspeaker or the earphone, and the transmitted words can be received through the oups decoding.
The invention has the beneficial effects that: the intercom device can realize the function of intercom of a plurality of people or intercom of appointed personnel through the design of software and hardware, can be applied to catering and security industries, has wider application range and strong practicability and compatibility, can avoid zero-distance contact of users, can enjoy specific private services in the catering industry to protect the privacy of the users as much as possible, can also select to mobilize a plurality of service personnel in a short time to meet the requirements of the users, improves the service efficiency and meets the experience of the users.
