Detailed Description
The following detailed description of specific embodiments of the present disclosure is provided in connection with the accompanying drawings. It should be understood that the detailed description and specific examples, while indicating the present disclosure, are given by way of illustration and explanation only, not limitation.
The embodiment of the disclosure can be applied to a limited space, and the detection device identifies the direction of the detected device when the detection device and the detected device are in a moving or static scene. For example, application scenarios include, but are not limited to, robot hunting, drone orientation, virtual barrier to sweeper, and balance car following.
Example one
Referring to fig. 1, fig. 1 is a flowchart illustrating a wireless positioning method according to an embodiment of the disclosure. The method is applied to the detected equipment, and as shown in fig. 1, the wireless positioning method comprises the following steps:
s11, generating detected request information when a preset trigger event is determined to occur;
and S12, sending detected request information to the detecting device, wherein the detected request information is used for requesting the detecting device to locate the detected device.
Specifically, the detected device may generate and send detected request information to the detecting device when a preset trigger event occurs, where the detected request information may include a synchronization signal, status flag bit information, and the like, and is used to request the detecting device to locate the detected device. The preset trigger event may be that the detected device moves, and/or the detected device reaches a preset period duration. Illustratively, the detected device is in a moving state, and when the position of the detected device changes, the detected device generates detected request information; or, when the detected device is in a static state, the detected device generates detected request information in a period of 5s, which is used for requesting the detecting device to locate the detected device.
Optionally, the probed request information comprises first identification information of the probed device, and the first identification information may be a feature code of the probed device, such as a serial number of the probed device. When the feature code is coded and modulated, the modulation and coding modes for carrying the feature code include, but are not limited to, physical layer technologies corresponding to communication technologies such as WIFI, BT, ZIGBEE, and LTE, and different physical layer technologies are applied, and the transmission periods corresponding to the detected request information are also different. Because the first identification information of the detected equipment has unique identification, that is, the first identification information of different detected equipment is also different, when a plurality of detected equipment sends detected request information in a limited space, the detection equipment can conveniently identify the identity of the detected equipment by receiving the detected request information carrying the first identification information of the detected equipment, and the accuracy of matching the positioning information is improved.
In one possible implementation, before the detected device sends the detected request information to the detecting device, it is determined whether the communication mode between the detected device and the detecting device is a one-to-one communication mode. The determination of the two-party communication mode can be negotiated by a higher-level communication protocol, for example, a negotiation protocol of a transmission frame content domain, or an initial configuration layer is configured through a WEB page, a button and the like, and the selection result of the communication mode is reflected by the configuration difference of the status bit on a wireless frame. Illustratively, the status BIT0 is 1, which indicates that the communication mode between the probed device and the probing device is a one-to-one communication mode, then second identification information of the probing device is obtained, where the second identification information may be a feature code of the probing device, such as a serial number of the probing device, and then the scrambling operation is performed on the first identification information according to the second identification information to obtain the probed request information including the scrambled first identification information; the status BIT0 is 0, which indicates that the communication mode between the detected device and the detecting device is one-to-many communication mode, and no scrambling operation is performed on the first identification information. The second identification information of the detecting device has unique identification, that is, the second identification information of different detecting devices is also different, so that after the detected request information sent by the detected device is subjected to scrambling operation by the second identification information of a certain detecting device, the detected request information of the obtained scrambled first identification information can only be descrambled and identified by the detecting device, and the confidentiality of communication between the detected device and the detecting device is ensured.
By adopting the method, when a preset trigger event occurs, the detected equipment can actively send the detected request information to request the detection equipment to position the detected equipment, and when the two-party communication mode is one-to-one communication, the second identification information of the detection equipment is used for scrambling the first identification information of the detected equipment, so that the accuracy of information matching in the positioning process is enhanced, the method has simple steps and is easy to operate, and the efficiency of the positioning process of the detected equipment can be effectively improved.
Example two
Referring to fig. 2, fig. 2 is a flowchart of a wireless positioning method according to an embodiment of the disclosure. The method is applied to a detection device with an antenna, wherein the antenna has a plurality of detection directions, and as shown in fig. 2, the wireless positioning method comprises the following steps:
s21, receiving the detected request information sent by the detected device;
the detection device receives detected request information sent by the detected device, wherein the detected request information is used for requesting the detection device to locate the detected device. In particular, the detection device has an antenna for transmitting and receiving signals, for example a directional antenna, which has one or several detection directions in which the antenna has a high ability to transmit and receive electromagnetic waves. It should be noted that the detection direction of the directional antenna may coincide with the visual direction of the directional antenna, or there may be a certain angle, and the detection device may rotate according to the detection direction of the directional antenna, or may receive the surrounding signal through its own rotation.
Optionally, before receiving the probed device sent probed request information, determining whether the communication mode between the probing device and the probed device is a one-to-one communication mode. If the communication mode between the detecting device and the detected device is a one-to-one communication mode, determining second identification information of the detecting device, where the second identification information may be a feature code of the detecting device, such as a serial number of the detecting device, and then, after receiving detected request information sent by the detected device, descrambling scrambled first identification information included in the detected request information according to the second identification information to obtain first identification information of the detected device, so as to determine the identity of the detected device.
S22, counting the signal strength of the detected request information received in each detection direction in the coverage of the antenna;
specifically, the detection device polls and receives the detected request information in each detection direction within the coverage of the antenna by using the antenna, and counts the signal strength of the detected request information correspondingly received in each detection direction of the antenna. The counted Signal Strength value of the detected request information may be a value of RSSI (Received Signal Strength Indication) used for determining link quality on the wireless transmission layer, or a value of RSCP (Received Signal Code Power) of a signature Code in the first identification information of the detected device Received on the physical channel, or a value of other related parameters such as a critical parameter RSRP (Reference Signal Receiving Power) representing wireless Signal Strength.
It should be noted that, which related parameter of the signal strength of the detected request information is specifically selected as the statistical target, may be selected according to different communication technologies used in the actual implementation process of the wireless positioning method, and the number of times that the detected device sends the detected request information is not less than the number of times that the antenna polls the detected request information in each detection direction within the coverage range of the receiving antenna, so as to ensure that the antenna can receive the detected request information sent by the detected device at least once in each detection direction. For example, the detected device is an object a, the detecting device is an object B, the antenna of the object B has 6 detecting directions, and the object B polls the 6 detecting directions to receive the detected request information sent by the object a, so as to complete the statistics of the signal strength in each detecting direction. In order to enable the object B to receive the detected request information sent by the object a in 6 detection directions, the object a needs to send the detected request information at least 6 times.
And S23, determining the position information of the detected device according to the signal intensity.
In a possible implementation manner, after counting the signal strength of the detected request information received corresponding to each detection direction of the antenna, the direction with the strongest signal strength of the detected request information is marked as a target direction, and the location information of the detected device is determined according to the target direction.
Specifically, the antenna of the detection device polls different detection directions to receive the detected request information sent by the detected device, and marks an included angle between the direction in which the signal of the detected request information is strongest and the visual direction of the antenna, where the included angle is the target direction. For example, determining the orientation of the probed device based on the target direction may be performed by: the antenna is provided with i detection directions, and the maximum radiation directions of the i antennas respectively form clockwise included angles a with the visual direction of the antenna1、a2、a3……aiCorresponding to the i probing directions, the signal strength of the received probed request information is calculated to be r1、r2、r3……riThen vector (∑ r)i*sin(ai),∑ri*cos(ai) Angle) is indicative of the orientation of the device being detected relative to the visual direction of the antenna. For example, when the maximum radiation directions of the four antennas respectively form clockwise included angles of 0 °, 90 °, 180 ° and 270 ° with the visual direction of the antenna, the statistical signal strengths of the received detected request information corresponding to the four detection directions are respectively R1、R2、R3And R4Vector (R) obtained by calculation according to the above-described orientation determining method2-R4,R1-R3) The angle of (a) represents the orientation of the detected device relative to the visual direction of the antenna.
The marking process of the target direction is carried out in real time and is continuously updated along with the detected request information received each time. Therefore, if the clockwise included angle between the target direction and the antenna visual direction is α after the detected request information is received in the first antenna polling detection direction, the process of determining the direction of the detected device is as follows: and if the clockwise included angle between the target direction and the visual direction of the antenna is beta, continuing to rotate the visual direction of the antenna of the detection equipment to the clockwise direction, and then carrying out the third time of polling detection of the antenna to receive the detected request information and mark the current target direction. And repeating the process of receiving the detected request information in the antenna iterative polling detection direction until the target direction is consistent with the visual direction of the antenna.
The method can determine the position of the detected equipment, and can specifically calculate the distance according to the attenuation condition of the signal intensity of the detected request information for more accurate positioning result.
EXAMPLE III
The embodiment of the disclosure also provides a method for interaction between the detected device and the detecting device. Referring to fig. 3, fig. 3 is a schematic diagram of interaction between a detected device and a detecting device according to an embodiment of the present disclosure. As shown in fig. 3, the method comprises the steps of:
s31, when the detected device determines that a preset trigger event occurs, generating detected request information;
s32, determining a communication mode between the detected device and the detecting device;
s33, the detected device sends detected request information to the detecting device;
s34, the detection device receives the detected request information sent by the detected device;
s35, the detection device counts the signal strength of the detected request information received in each detection direction in the coverage of the antenna;
and S36, the detection device determines the position information of the detected device according to the signal intensity.
In the process of interaction between the detection device and the detected device, firstly, the detected device generates detected request information when a preset trigger event is determined to occur, correspondingly processes the detected request information according to a communication mode under the condition that the communication mode between the detected device and the detection device is determined, and finally sends the detected request information to the detection device. Illustratively, the probed request information comprises first identification information of the probed device, the first identification information is scrambled according to second identification information of the probing device when the probed device and the probing device are in a one-to-one communication mode, and the probed request information is not processed when the probed device and the probing device are in a one-to-many communication mode. After receiving the detected request information sent by the detected device, the detecting device counts the signal strength of the detected request information received in each detection direction within the coverage area of the antenna, and determines the position information of the detected device according to the signal strength, so as to realize the positioning of the detected device. Optionally, when the detected device and the detecting device are in a one-to-one communication mode, the detecting device needs to descramble the received scrambled first identification information of the detected request information according to the second identification information to obtain the first identification information of the detected device, so that the detecting device can identify the identity of the detected device conveniently.
It should be noted that, in the antenna positioning system, each communication node device may be a probe device or a device to be probed, or a certain communication node device is both a probe device and a device to be probed.
The interaction process between the detected equipment and the detecting equipment is carried out, the detected equipment and the detecting equipment cooperate with each other through the interaction process, the position information of the detected equipment can be analyzed and determined according to the signal strength received by the antenna at different detection angles, the method is simple to operate, and the efficiency of the positioning process of the detected equipment can be effectively improved.
