Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is further described in detail with reference to the accompanying drawings.
In order to realize the relative direction positioning between the intelligent devices by using software without additionally adding hardware, so that the relative positioning has universality, the devices of different manufacturers can realize interoperation and mutual compatibility, and the innovative application of the intelligent devices is explored on the basis of the interoperation and the compatibility, the embodiment of the invention provides a sound (preferably ultrasonic) based relative direction identification scheme between the intelligent devices, the hardware is not required to be additionally added, the software can be used for realizing the relative direction identification between the two intelligent devices, and the positioning result is accurate and reliable. First, an intelligent device (intelligent device) refers to any device, apparatus or machine having computing processing capabilities.
Fig. 1 is an exemplary flowchart of a method for determining a relative angle between smart devices according to the present invention. The method is applicable to a first intelligent device which comprises a first sound detection module and a second sound detection module. The first sound detection module and the second sound detection module are fixedly installed in the first intelligent device. For example, the first sound detection module may be implemented as one microphone or a set of microphone arrays arranged in the first smart device. Likewise, the second sound detection module may be implemented as one microphone or a set of microphone arrays arranged in the first smart device different from the first sound detection module.
As shown in fig. 1, the method includes:
step 101: enabling the first sound detection module to detect a first sound signal sent by the second intelligent device and directly reaching the first sound detection module, and enabling the second sound detection module to detect a second sound signal sent by the second intelligent device and directly reaching the second sound detection module, wherein the first sound signal and the second sound signal are sent by the second intelligent device at the same time.
Here, the second smart device may emit one sound signal or emit a plurality of sound signals at the same time.
Such as: when the second intelligent device sends out a sound signal, the first sound detection module and the second sound detection module in the first intelligent device respectively detect the sound signal. Wherein: the detection signal, which is detected by the first sound detection module and is directly transmitted to the first sound detection module, is determined as a first sound signal; the detection signal detected by the second sound detection module, which is the sound signal that reaches the first sound detection module, is determined as the second sound signal.
For another example, when the second smart device emits multiple sound signals simultaneously, such as an ultrasonic signal and an audible sound signal. A first sound detection module in the first smart device is adapted to detect ultrasonic signals and a second sound detection module is adapted to detect audible sound signals. The first sound detection module detects the ultrasonic signal, and the second sound detection module detects the audible sound signal. Wherein: the detection signal, which is detected by the first sound detection module and through which the ultrasonic signal reaches the first sound detection module, is determined as a first sound signal; the detection signal detected by the second sound detection module, at which the audible sound signal reaches the second sound detection module, is determined to be a second sound signal.
In other words, the first sound signal and the second sound signal may be respective detection signals of the first sound detection module and the second sound detection module for the same sound signal emitted by the second smart device. Or, the first sound signal and the second sound signal may be respective detection signals of different sound signals emitted by the first sound detection module and the second sound detection module simultaneously for the second smart device.
Step 102: a time difference between the moment of reception of the first sound signal and the moment of reception of the second sound signal is determined.
Here, the first smart device (e.g., a CPU in the first smart device) may record the reception timing of the first sound signal and the reception timing of the second sound signal, and calculate a time difference between the two.
Step 103: and determining a relative angle between the first intelligent device and the second intelligent device based on the distance between the first sound detection module and the second sound detection module and the time difference.
For example, step 103 may be performed by the CPU of the first smart device.
In one embodimentDetermining the relative angle between the first smart device and the second smart device in step 103 includes: based on
Determining theta; wherein arcsin is an arcsine function, D is t × c, t is the time difference, c is the propagation speed of sound, and D is the distance between the first sound detection module and the second sound detection module; determining a relative angle between a first smart device and a second smart device based on θ
Wherein
The value of the time difference determined in step 102 may be a positive number or a negative number. When the value of the time difference is positive, the receiving time of the second sound signal is earlier than the receiving time of the first sound signal, so that the relative angle phi between the first intelligent device and the second intelligent device is generally an acute angle; when the value of the time difference is negative, the receiving time of the first sound signal is earlier than the receiving time of the second sound signal, so the relative angle phi between the first smart device and the second smart device is generally obtuse.
In an embodiment of the present invention, the first sound signal is a signal that is directly transmitted to the first sound detection module from the second smart device, and the second sound signal is a signal that is directly transmitted to the second sound detection module from the second smart device. In fact, either the first sound detection module or the second sound detection module may receive a signal that is emitted from the second smart device and is not direct (e.g., a reflection or multiple emissions past an obstacle). Therefore, how to determine the direct signal from the received multiple signals has a significant meaning.
The applicant found that: typically, the received signal stream (steam) of each sound detection module comprises a direct channel and a reflected channel. The direct channel can be determined simply and conveniently according to the following principle: the signal strength of the direct channel is typically strongest among all the signals detected by the sound detection module. Thus, in one embodiment, the method further comprises: the method comprises the steps that a first sound detection module receives sound signals with the intensity larger than a preset threshold value in a preset time window in sound signal streams of second intelligent equipment, and the sound signals are determined to be the first sound signals; and determining that the sound signal with the intensity larger than the preset threshold value in the preset time window in the sound signal stream of the second intelligent device is received by the second sound detection module as the second sound signal.
Fig. 4 is a first exemplary diagram of determining a pair of direct signals according to the present invention. In fig. 4, the sound signal stream detected by the first sound detection module is steam1, the steam1 contains a plurality of pulse signals varying along time (T), and the threshold value of the predetermined signal strength is T. It can be seen that the signal strength of the pulse signal 50 in steam1 is greater than the threshold value T over the range of time window 90. The sound signal stream detected by the second sound detection module is steam2, the steam2 contains a plurality of pulse signals varying along time (T), and the threshold value of the predetermined signal strength is also T. It can be seen that the signal strength of the pulse signal 60 in steam2 is greater than the threshold value T over the range of time window 90. Thus, the pulse signal 50 is determined to be the first sound signal; the pulse signal 60 is a second sound signal.
In addition, the applicant has also found that: the direct channel can be accurately determined by comprehensively considering the following two principles: principle (1), among all signals detected by the sound detection module, the signal strength of the direct channel is generally strongest; principle (2), joint discrimination: the distance difference d converted from the arrival time difference of two direct channel signals (the first sound signal and the second sound signal) should not be larger than the distance between the first sound detection module and the second sound detection module.
Thus, in one embodiment, the method further comprises: determining sound signals with the intensity larger than a preset threshold value in a sound signal stream of second intelligent equipment detected by a first sound detection module to form a first candidate signal set; determining sound signals with the intensity larger than the preset threshold value in the sound signal flow of the second intelligent device detected by the second sound detection module to form a second candidate signal set; determining a respective time difference between a time of receipt of each sound signal in the first candidate signal set and a time of receipt of each sound signal in the second candidate signal set; and determining a pair of sound signals with the time difference smaller than M as the first sound signal and the second sound signal, wherein M is (D/c), D is the distance between the first sound detection module and the second sound detection module, and c is the propagation speed of sound.
Fig. 5 is a second exemplary diagram illustrating the determination of a pair of direct signals according to the present invention. In fig. 5, the sound signal stream detected by the first sound detection module is steam1, the steam1 contains a plurality of pulse signals varying along time (T), and the threshold value of the predetermined signal strength is T. It can be seen that in steam1, the signal strength of the pulse signal 50 is greater than the threshold value T, and therefore the first set of candidate signals contains the pulse signal 50. The sound signal stream detected by the second sound detection module is steam2, the steam1 contains a plurality of pulse signals varying along time (T), and the threshold value of the predetermined signal strength is also T. It can be seen that in steam2, the signal strength of both pulse signal 60 and pulse signal 70 is greater than the threshold value T, and therefore the second set of candidate signals includes pulse signal 60 and pulse signal 70. Furthermore, a time difference d1 between the reception instants of the pulse signal 50 in the first candidate signal set and the pulse signal 60 in the second candidate signal set is determined, and a time difference d2 between the reception instants of the pulse signal 50 in the first candidate signal set and the pulse signal 70 in the second candidate signal set is determined. Assuming that D1 is smaller than M and D2 is larger than M, where M ═ D/c, D is the distance between the first and second sound detection modules, and c is the propagation speed of sound. Therefore, the pulse signal 50 of the pair of sound signals related to d1 is determined as the first sound signal, and the pulse signal 60 of the pair of sound signals is determined as the second sound signal.
Preferably, the first and second sound signals are ultrasonic waves having a code division multiple access format and contain a media access control address (MAC) of the second smart device. Accordingly, the first smart device can accurately identify the source of the sound signal based on the MAC address of the second smart device contained in the sound signal. When a plurality of sound sources emitting sound signals exist in the environment, the first intelligent device can accurately determine the relative angle with the sound source by using two direct signals from the same sound source without being interfered by other sound sources based on the extraction of the MAC address in the sound signals.
The embodiment of the invention also provides a relative angle determination method between the intelligent devices. The method is applicable to a first intelligent device, wherein the first intelligent device comprises a first sound detection module and a second sound detection module, and the method comprises the following steps: determining a first moment when an ultrasonic signal sent by second intelligent equipment directly reaches a first sound detection module; determining a second moment when the ultrasonic signal directly reaches the second sound detection module; determining a time difference between the first time and the second time; and determining a relative angle between the first intelligent device and the second intelligent device based on the distance between the first sound detection module and the second sound detection module and the time difference.
In one embodiment, the determining the relative angle between the first smart device and the second smart device comprises: based on
Determining theta; wherein arcsin is an arcsine function, D is t × c, t is the time difference, c is the propagation speed of sound, and D is the distance between the first sound detection module and the second sound detection module; determining a relative angle between a first smart device and a second smart device based on θ
Wherein
In one embodiment, the method further comprises at least one of the following processes:
(1) determining the ultrasonic signal with the intensity larger than a preset threshold value in a preset time window in the ultrasonic signal stream of the second intelligent device received by the first sound detection module as the ultrasonic signal directly reaching the first sound detection module, and determining the time of receiving the ultrasonic signal directly reaching the first sound detection module as the first time; and determining the ultrasonic signal with the intensity larger than the preset threshold value in the preset time window in the ultrasonic signal flow of the second intelligent device received by the second sound detection module as the ultrasonic signal of the direct second sound detection module, and determining the time of receiving the ultrasonic signal of the direct second sound detection module as the second time.
(2) Determining ultrasonic signals with the intensity larger than a preset threshold value in ultrasonic signal streams of the second intelligent device detected by the first sound detection module to form a first candidate signal set; determining the ultrasonic signals with the intensity larger than the preset threshold value in the ultrasonic signal flow of the second intelligent device detected by the second sound detection module to form a second candidate signal set; determining a respective time difference between the time of receipt of each ultrasonic signal in the first candidate signal set and the time of receipt of each ultrasonic signal in the second candidate signal set; and determining the receiving time of the pair of ultrasonic signals with the time difference smaller than M as the first time and the second time, wherein M is (D/c), D is the distance between the first sound detection module and the second sound detection module, and c is the propagation speed of sound.
The principle and calculation process of the relative positioning of the present invention are exemplarily explained as follows. Fig. 2 is a schematic diagram illustrating the principle of relative angle determination between smart devices according to the present invention. FIG. 3 is a schematic diagram of the calculation of relative angles between smart devices according to the present invention.
As shown in fig. 2, a microphone a1 disposed at the bottom of smart device a emits an ultrasonic signal containing the MAC address of smart device a, and smart device B (not shown in fig. 2) has two microphones, microphone B1 and microphone B2, respectively, disposed at a distance. Wherein: the microphone b1 receives the direct signal L1 of the ultrasonic signal, and the microphone b2 receives the direct signal L2 of the ultrasonic signal. The ultrasonic signals reach the indirect signals of the microphone b1 and the microphone b2 after being transmitted by the obstacles, and do not participate in the subsequent relative angle calculation.
Due to intelligenceThe energy equipment is small, especially when two intelligent equipments are far away, so the direct signal L1、L2Can be considered as parallel lines. As shown in FIG. 3, L1、L2Direct signals (not signals reflected by obstacles) received by the microphone B1 and the microphone B2 of the smart device B, respectively; d is the distance between microphone b1 and microphone b 2. For example, if the microphone B1 and the microphone B2 are respectively disposed at the upper and lower ends of the smart device B, D may be the length of the smart device B; d is L1And L2Using a correlation algorithm of the signals, the direct signal L can be determined1Relative to the direct signal L2D may be calculated based on the delay time difference t, where d is t × c, and c is the propagation speed of sound in a medium (such as air); theta is an auxiliary angle, wherein
Therefore, the relative angle of the intelligent device A and the intelligent device B can be calculated
Wherein
Preferably, smart device a and smart device B may be implemented as at least one of: a smart phone; a tablet computer; a smart watch; a smart bracelet; an intelligent sound box; a smart television; an intelligent earphone; smart robots, and the like. The first sound detection module and the second sound detection module may be arranged at a plurality of locations of the smart device.
Fig. 6 is a schematic diagram of a first exemplary arrangement of a first sound detection module and a second sound detection module in a smart device according to the present invention. In fig. 6, the first sound detection module 18 and the second sound detection module 19 are respectively disposed at both ends of the smart device in the length direction, and thus the length D of the smart device can be directly determined as the distance between the first sound detection module 18 and the second sound detection module 19. Fig. 7 is a schematic diagram of a second exemplary arrangement of a first sound detection module and a second sound detection module in a smart device according to the present invention. In fig. 7, the first sound detection module 18 and the second sound detection module 19 are respectively disposed at both ends of the smart device in the width direction, and thus the width D of the smart device can be directly determined as the distance between the first sound detection module 18 and the second sound detection module 19.
The above exemplary descriptions have been provided for the arrangement of the first sound detection module and the second sound detection module in the smart device, and those skilled in the art will appreciate that such descriptions are merely exemplary and are not intended to limit the scope of the embodiments of the present invention.
In fact, currently, a smart device usually has two sets of microphones, and the two sets of microphones can be applied to the embodiment of the present invention as the first sound detection module and the second sound detection module without changing the smart device in terms of hardware. The following describes a typical example of calculating a relative angle between smart devices using ultrasound based on an embodiment of the present invention.
Fig. 8 is a schematic diagram of the relative positioning of a first smart device and a second smart device in accordance with the present invention. FIG. 10 is a flowchart illustrating an exemplary process for relative positioning between smart devices according to the present invention. In fig. 7, respective processing paths of two combined microphones detecting sound signals are illustrated, in which an Analog-to-Digital Converter (ADC) is a device converting an Analog signal of a continuous variable into a discrete Digital signal; a band-pass filter (BPF) is a device that allows waves of a particular frequency band to pass while shielding other frequency bands. The ultrasonic-based relative direction identification step between two intelligent devices comprises the following steps:
the first step is as follows: the first smart device transmits a location signal in ultrasound format containing the Mac address of the smart device 1. The second step is that: and the two groups of microphones of the second intelligent device respectively detect the positioning signals, resolve the Mac address from the respective detected positioning signals, and confirm that the respective detected positioning signals originate from the same sound source based on the Mac address. The third step: the second intelligent device detects two positioning signals respectively based on two groups of microphones contained in the second intelligent deviceThe time difference between the two direct signals calculates the distance difference d between the two direct signals. The fourth step: second smart device computing
The incident angle of the signal
I.e. the relative angle of the first smart device and the second smart device, where D is the distance between the two sets of microphones in the second smart device. The fifth step: the second intelligent device displays the relative angle on the display interface of the second intelligent device
Thereby prompting the user for the relative orientation of the first smart device. For example, fig. 9 is a schematic diagram showing relative angles in an interface of a smart device according to the present invention.
For example, assume that in the environment shown in fig. 8, the first smart device is embodied as a smart speaker and the first smart device is embodied as a smart phone. The method comprises the following steps: the intelligent sound box transmits an ultrasonic signal, wherein the ultrasonic signal comprises a Mac address of the intelligent sound box and is a signal based on a CDMA (code division multiple access) technical framework. Step two: the two sets of microphone arrays of the smart phone receive the ultrasonic signals and solve a Mac address of the smart sound box, and meanwhile, the smart phone solves a distance difference d between two direct signals of the two sets of microphone arrays. Wherein: suppose that in the respective received signal streams stream1 and stream2 of the two groups of microphone arrays, there are direct signals whose signal intensity peaks are greater than the threshold value T, respectively, and thus the principle 1 is satisfied; further assume the arrival time difference of the two direct signals
Calculating d corresponding to the Δ t, wherein
The two sets of microphone distances D are known (i.e. the handset length), assuming 0.145m, and D < D is visible, thus satisfying principle 2. Therefore, the two direct signals can be selected to calculate the relative angle, where d is 0.014 (m). Step three: smartphone computing
Then the angle of incidence of the signal
The smart phone displays an angle of 84.4 degrees on a display screen of the smart phone, namely the smart sound box is in the direction of 84.4 degrees of the smart phone.
By using the identification method of the relative direction between the two intelligent devices, the relative distance between the two intelligent devices can be further obtained. The following scenario is envisaged: the system comprises at least two intelligent devices, wherein at least one intelligent device a is used for transmitting an ultrasonic positioning signal, and the ultrasonic positioning signal contains the MAC address of the intelligent device a; and the intelligent equipment b is used for receiving the ultrasonic positioning signal, resolving the incident angle of the signal and calculating the relative distance between the intelligent equipment b and the intelligent equipment a after further movement.
In order to meet the requirements of controlling cost, quickly arranging and using a mobile terminal to realize accurate positioning of indoor personnel in a small-space application scene, the invention also provides an indoor positioning method and system with simple small-space arrangement. The indoor positioning system includes a plurality of smart devices arranged indoors as a sound source and a positioned mobile terminal for receiving the sound. Each sound source has a respective deployment location for transmitting a sound-formatted (preferably ultrasonic) location signal containing the MAC address of the smart device.
And the positioned mobile terminal receives and calculates the incident angle of each direct positioning signal so as to obtain the relative position of the positioning request user, and the relative position is corresponding to the cloud indoor map, so that the position sharing of each positioning request user in an indoor environment is realized.
Based on the above description, the embodiment of the present invention further provides a technical solution for implementing intelligent ticket counting based on the above relative angle calculation manner.
Fig. 11 is a structural view of the ticket counter of the present invention. Preferably, the deployment position of the vote counting device is fixed, so that a user can conveniently position the intelligent equipment to realize voting.
As shown in fig. 11, the ticket counting apparatus includes:
the first sound detection module is used for detecting a first sound signal which is directly transmitted from the intelligent equipment to the first sound detection module;
the second sound detection module is used for detecting a second sound signal which is directly transmitted from the intelligent equipment to the second sound detection module; wherein the first sound signal and the second sound signal are emitted by the smart device simultaneously;
an angle determining module, configured to determine a time difference between a receiving time of the first sound signal and a receiving time of the second sound signal; determining a relative angle between the ticket counting device and the intelligent device based on the distance between the first sound detection module and the second sound detection module and the time difference;
and the vote counting module is used for determining the preset angle range to which the relative angle belongs and determining the voting result corresponding to the preset angle range to which the relative angle belongs.
The intelligent device is a voting device of the user. The smart device may emit a sound signal (preferably an ultrasound signal) as a sound source. For example, the smart device may be implemented as a sound generating device such as a smart phone, a personal digital assistant, a tablet computer, a smart speaker, or a smart television. More preferably, the smart device is implemented as a smartphone, personal digital assistant, tablet computer, or other mobile-suitable device.
And informing the voting users of the association relationship between the preset angle range and the voting result in advance. For example, the vote counting device may send a notification message to all the voting users' smart devices in a group (e.g., via wireless communication, WI-FI communication, bluetooth communication, infrared communication, etc.) in advance, where the notification message includes an association relationship between the predetermined angle range and the voting result.
For example, assume that there are 3 predetermined angular ranges, respectively [0 degrees, 45 degrees ], (45 degrees, 90 degrees ], and (90 degrees, 180 degrees ]. where, the voting result corresponding to [0 degree, 45 degrees ] is "approved", "the voting result corresponding to (45 degrees, 90 degrees) is" disclaimed ", and the voting result corresponding to (90 degrees, 180 degrees) is" objected ". "Please note: voting result "approve" corresponding to [0 degree, 45 degrees ]; (45 degrees, 90 degrees.) the corresponding voting result is "disclaimer"; (90 degrees, 180 degrees.) the corresponding voting results are "against". accordingly, after each voting user views the notification message, then, the voting users can express the voting results of themselves by fiddling with the direction of the intelligent equipment to meet the corresponding angle range.
In one embodiment, N predetermined angle ranges are preset in the vote counting module, and each predetermined angle range corresponds to a respective voting result, where N is a positive integer of at least 2.
