Detailed Description
The technical solutions in the embodiments of the present invention are clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments of the present invention without making any creative effort, shall fall within the protection scope of the present invention.
Embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.
The embodiment provides a space-time internet of things-based equipment detection and control system. Fig. 1 is a structural diagram of a space-time internet of things based device detection and control system according to this embodiment. As shown in fig. 1, the space-time internet of things based equipment detection and control system includes: a plurality of devices and a control platform.
The equipment in this embodiment can be for the smart machine that possesses the voice interaction function, like smart audio amplifier, smart mobile phone, intelligent wrist-watch etc. have smallness smart audio amplifier, tianmao eidolon etc. in the existing market. Certainly, the device in this embodiment may also be an intelligent device capable of recognizing the wake-up signal, where the wake-up signal may be not only a voice signal, such as different wake-up words "small degree", "little love classmate", and the like, but also an externally input signal (such as a key provided by the device itself), where the device in this embodiment is woken up through the input information, and the wake-up signal may also be a signal sent by another home internet of things device, such as a wake-up signal sent by a smart phone, a smart wearable device, and the like. Therefore, the device in this embodiment is not limited as long as the device capable of recognizing the wake-up signal to execute the corresponding function can be identified.
Taking the smart speaker as an example, the smart speaker has a powerful voice recognition function, and can perform various operations through voice interaction with a user. At present, a family purchases a plurality of intelligent devices, and in many cases, when facing a living environment of a Chinese family and having a plurality of sound boxes in the family, the situation that a plurality of sound boxes answer at the same time by shouting a sentence of awakening words often appears. Meanwhile, due to the fact that the distances between the sound box device and the user are different, the sound box far away from the user often has poor receiving effect when receiving the voice instruction, so that the voice recognition is wrong, and as a result, a plurality of sound boxes which are awakened up all start to execute the instruction to play sound, but the sound boxes far away generally execute wrong instructions. At this time, the user should send a stop instruction to the smart device executing the wrong instruction again, which causes a cumbersome or inconvenient use and poor interaction experience.
To solve the above technical problem, the present embodiment provides a space-time internet of things-based device detection and control system. Wherein:
each device is used for respectively acquiring a wake-up signal; determining time information for acquiring the wake-up signal; sending a wake-up request to the control platform, the wake-up request comprising: identification information and time information;
the control platform is used for receiving a plurality of awakening requests and determining the equipment to be awakened, and the equipment to be awakened comprises: the equipment corresponding to the identification information with the earliest time information; sending a wake-up instruction to the equipment to be woken up;
and the equipment to be awakened is used for receiving the awakening instruction and executing the awakening operation.
The equipment detection and control system based on the space-time internet of things can be applied to the scene where multiple intelligent sound boxes coexist, the control platform can rapidly select an intelligent box which is most likely to be awakened by a user according to time information, the condition that voice interaction is disordered due to the fact that multiple intelligent sound boxes are awakened simultaneously is avoided, the efficiency and the quality of the voice interaction are improved, and user experience is better.
In this embodiment, the time information may be a timestamp. After each device receives and recognizes the wake-up signal, the timestamp of the wake-up word can be determined and obtained, and the timestamp is used as time information and sent to the control platform. The identification information is a serial number or an MAC address of the device, the device can be uniquely identified, and each device carries respective identification information when sending the wake-up request. Therefore, the control platform can determine the device which acquires the wake-up signal firstly according to the sequence of the timestamps, namely the device corresponding to the identification information with the earliest time information, and sends a wake-up instruction to the corresponding device according to the identification information to execute the wake-up operation. The control platform is a server and is communicated with a plurality of devices simultaneously, and normal awakening of each device is guaranteed.
As an optional implementation manner in this embodiment, each device is further configured to perform time synchronization with the control platform. The control platform can accurately judge the equipment with the earliest time for receiving the wake-up signal according to the time information reported by each equipment.
As an optional implementation manner in this embodiment, the multiple devices are further configured to receive the wake-up signal at preset intervals before acquiring the wake-up signal. In a home, when there are a plurality of devices to be woken up, a user can perform a device for a time interval in which each device receives a wake-up signal. For example, the mini-speaker detects whether a wake-up signal is received every 10 minutes, the tianmao puck detects whether a wake-up signal is received every 20 minutes, and the air purifier detects whether a wake-up signal is received every 1 hour. Thereby power consumption can be saved.
As an optional implementation manner in this embodiment, each device is further configured to obtain distance information between a location where the wake-up signal is sent and each device; the wake-up request further comprises: and (4) distance information. The device to be woken up further comprises: and the equipment corresponding to the identification information with the shortest distance information. When the positions of a plurality of devices are different from the position of a user sending a wake-up signal, the device closest to the user can be determined to be the device which the user wants to wake up most, so that the control platform can determine the device corresponding to the identification information with the shortest distance information if the time information is the same or the difference is not much after receiving the wake-up request; sending the awakening instruction to equipment corresponding to the identification information with the shortest distance information; and the equipment corresponding to the identification information with the shortest distance information is used for receiving the awakening instruction and executing the awakening operation. From this, control platform can also select out the intelligence that the user most probably awakens up according to distance information fast, avoids because many intelligent audio amplifier awaken up the chaotic condition of voice interaction that brings simultaneously, improves voice interaction's efficiency and quality, and user experience is better.
The embodiment also provides a space-time internet of things-based equipment detection and control method.
