For above-mentioned application scenarios, the embodiment of the present invention provides a kind of method for controlling equipment, as shown in Figure 1, this method
Specifically comprise the following steps:
Step 100, according to the position and the distance between acquisition position for issuing audio controls from all acquisition positions
At least one target position of middle determination；
Step 101, the first voice signal is determined according to the voice signal that at least one described target location is got, with

Make the accuracy of order.
Executing subject in the embodiment of the present invention can be server, be also possible to controller；
Smart home device can be intelligent air condition, intelligent electric cooker, intelligent refrigerator, intelligent TV set etc..
It should be noted that can be arranged in the embodiment of the present invention more in order to preferably collect audio controls
User often movable region, such as sofa, the head of a bed etc. in a room can be set in a voice collector, each voice collector
At position, voice collector also can be set on smart home device.
Correspondingly, when multiple voice collectors being arranged in a room receiver can be installed on smart home device, to connect
Receive the collected voice signal of each voice collector.
Due to being provided with multiple voice collectors, in order to distinguish each voice collector, then it needs to be determined that voice collector
Location information.
The location information of voice collector can be determined according to following three kinds of modes:
Mode one is based on mobile device (mobile phone, glasses, wrist-watch etc.), sweeping robot etc., passes through built-in SLAM
(Simultaneous Localization And Mapping, synchronous positioning are schemed with foundation) positioning device and range sensor
Determine the relative position of voice collector, to establish the three-dimensional coordinate system of voice collector location information, and by this three
Dimension space coordinate system stores in the server.
For example, mobile phone is close to each voice collector, when the distance between mobile phone and voice collector are less than threshold value,
Signal is converted by the relative position information for the voice collector that SLAM positioning device determines, then passes through Wi-Fi
The signal that (Wireless-Fidelity, Wireless Fidelity) is converted into is sent to the receiver connecting with intelligent appliance equipment, connects
It receives device and sends the signal to server, server is according to each signal stored in each signal and server received
With the binding relationship of relative position, the three-dimensional coordinate system of voice collector location information is established.
It should be noted that the different corresponding signals of relative position information are different.
Mode two, the location information that voice collector is determined according to infrared sensor or camera, and by determining voice
The location information storage of collector is in the server.
For example, infrared sensor is mounted in intelligent appliance equipment, room information is then realized by principle of reflection
It obtains, server establishes three-dimensional coordinate system according to voice collector location information in the room got.
Mode three installs voice collector in fixed position, and installation site information is stored in service after installing
In device.
The location information i.e. acquisition position information of voice collector, by acquisition position information storage in the server with
Afterwards, server is determined from all acquisition positions according to the distance between the position and acquisition position that issue audio controls
Target position.
In an implementation, the distance between position and the acquisition position for issuing audio controls, can be according to voice control
It is determined at the time of signal reaches at all acquisition positions.
Specifically, a timer can be set at each acquisition position, the voice collector at the acquisition position is adopted
After collecting voice signal, then at the time of triggering the timer record and receive the voice signal, collected voice control is believed
Number and record at the time of be sent to server so that server is according to determining sending audio controls at the time of receiving
The distance between position and acquisition position.
For example, have 4 voice collectors, voice collector 1, voice collector 2, voice collector 3, voice collector 4,
Voice collector 1 corresponds to the corresponding acquisition position 2 of acquisition position 1, voice collector 2, voice collector 3 corresponding acquisition position 3, language
Sound collector 4 corresponds to acquisition position 4, and user A issues audio controls, when the audio controls reach voice collector 1
At the time of it is minimum, reach it is maximum at the time of voice collector 2, it is equal at the time of reaching voice collector 3 with voice collector 4,
Between at the time of reaching voice collector 1 and at the time of arrival voice collector 2, it is determined that issue the position of audio controls
It is most short to set the distance between acquisition position 1, the distance between acquisition position 2 longest, with acquisition position 3 and and acquisition position
4 are equidistant.
What needs to be explained here is that when determining the distance between the position for issuing audio controls and acquisition position, language
Sound control signal can also be wake-up signal.
If user can be used one section of wake-up word and wake up the intelligence for example, smart home device is in a dormant state
Home equipment can store wake-up word in server, when the voice messaging is sent to clothes by voice collector for example, " he, golden shellfish "
When business device, server, which is resolved in voice messaging, has " golden shellfish " this wake-up word, then server sets corresponding smart home
It is standby to wake up.Server is when waking up smart home device, at the time of arrival at each voice collector according to the wake-up word, determines
Issue the distance between the position for waking up word and acquisition position.
After the distance between the position for issuing audio controls and acquisition position has been determined, selected from all acquisition positions
Select target position.
Wherein, target position can be one, or multiple.
Preferably, if target position is one, distance is issued into the nearest acquisition position in audio controls position
As target position；
If target position has multiple, multiple target positions can be selected from all acquisition positions according to actual needs
It sets.
For example, if there are two target positions, by distance issue the nearest acquisition position in audio controls position with
And acquisition position the two positions close apart from sending audio controls position time are as target position.
After target position determines, determine that the first voice is believed according to the voice signal that determining target location is got
Number, and the second voice signal is determined according to the voice signal got at the acquisition position in addition to target position.
In an implementation, if there is a target position, then using the collected voice signal of the target location as first
Voice signal, if there is multiple target positions, then using the average value of the collected voice signal of multiple target locations as
One voice signal.
Using the average value of the voice signal got at the acquisition position in addition to target position as the second voice signal.
For example, have 4 voice collectors, voice collector 1, voice collector 2, voice collector 3, voice collector 4,
Voice collector 1 corresponds to the corresponding acquisition position 2 of acquisition position 1, voice collector 2, voice collector 3 corresponding acquisition position 3, language
Sound collector 4 corresponds to acquisition position 4, and determining target position is acquisition position 1, then by the collected voice of voice collector 1
Signal is as the first voice signal, by voice collector 2, voice collector 3, the collected voice signal of voice collector 4
Average value is as the second voice signal.
After first voice signal and the second voice signal determine, the second voice signal is filtered out from the first voice signal,
The corresponding control command of the voice signal after filtering out is controlled into smart home device again.
In embodiments of the present invention, since the first voice signal is nearest in the position that distance issues audio controls
It is got at acquisition position, so the intensity of audio controls is most strong in the first voice signal, but the first voice signal
In can also include some noise signals, such as other users issue control other smart home devices audio controls,
In order to improve the accuracy of the control command parsed, so needing to filter out the noise signal in the first voice signal.
Since the second voice signal is adopting in addition to the nearest acquisition position in the position that distance issues audio controls
The average value for the voice signal that Ji Weizhichu is got so the second voice signal is noise signal, that is, is needed from first
The signal filtered out in voice signal.
In an implementation, the method the second voice signal filtered out from the first voice signal, can be by the first voice signal
It is added with the reverse phase voice signal of the second voice signal.
Here the reverse phase voice signal of the second voice signal is, opposite in phase identical as the second voice signal amplitude
Voice signal.
By the second voice signal after being filtered out in the first voice signal, according to the corresponding control of voice signal after filtering out
Command control device.
Server parses the voice signal after filtering out, the control that will be stored in the voice messaging and server in voice signal
Order is compared, and obtains corresponding control command, then controls equipment according to the control command；If the voice after filtering out is believed
Number parsing failure, that is, the control command stored in the voice messaging and server in the voice signal after filtering out is compared
Clock synchronization cannot obtain corresponding control command, and server can push parsing failure news to user at this time.
In specific implementation, first the voice signal after filtering out can be amplified, then to amplified voice signal into
Row parsing, obtains corresponding control command, finally controls equipment according to the control command.
As shown in Fig. 2, for a kind of flow diagram for the complete method for controlling equipment of the embodiment of the present invention.
Step 200 determines the voice collector nearest apart from user according to the word that wakes up that user issues；
Step 201, using the collected voice signal of the voice collector nearest apart from user as the first voice signal；
It is step 202, other voice collectors in addition to the voice collector nearest apart from user distance are collected
The average value of voice signal is as the second voice signal；
Step 203 filters out the second voice signal from the first voice signal, obtains third voice signal；
Step 204 amplifies third voice signal；
Step 205, the amplified third voice signal of parsing；
Step 206 judges to parse whether third voice signal succeeds, if so, thening follow the steps 207, otherwise exit；
Step 207 controls equipment according to control command obtained after parsing.
