Technical Field

Background

In the monitoring industry, wireless cameras are more and more favored by customers due to the convenience of field installation and construction. The wireless camera is responsible for acquiring images/information, and the images/information is transmitted to network nodes such as a network video recorder or a wireless router by adopting a wireless technology, so that the deployment is very convenient.

If the connection quality is continuously poor, abnormal loss of images/information or even connection failure may be caused, at this time, the user may restart the device, and if the problem cannot be solved after the restart, maintenance personnel are required to adjust the antenna position of the wireless camera, which is high in maintenance cost and low in efficiency, especially under the condition that the installation position of the wireless camera is complex.

The following several specific embodiments may be combined with each other, and details of the same or similar concepts or processes may not be repeated in some embodiments. Embodiments of the present application will be described below with reference to the accompanying drawings.

An embodiment of the present invention provides an application environment for executing a method for adjusting a position of an antenna, and referring to fig. 1, the application environment includes: a first device 101 and a second device 102. The first device 101 and the second device 102 are connected via a Network, the first device 101 is an image capturing device, such as a camera, and the second device 102 is a Network node, such as a Network Video Recorder (NVR), a router, and the like. In the present application, the first device and the second device may communicate with each other through any communication method, including, but not limited to, 3GPP (3rd Generation Partnership Project), 4GPP (4rd Generation Partnership Project), 5GPP (5rd Generation Partnership Project), LTE (Long Term Evolution), WIMAX (World Interoperability for Microwave Access), TCP/IP (Transmission Control Protocol/Internet Protocol), UDP (User data Protocol), and short-range wireless Transmission methods based on bluetooth and near-field infrared Transmission standards.

It should be noted that, in the embodiment of the present invention, a first device and a second device are exemplified to communicate with each other. However, in practical applications, a plurality of first devices may communicate with one second device at the same time, and may be set according to practical requirements, which is not limited in the embodiment of the present invention.

Fig. 2 shows a structural architecture of the image capturing apparatus. Image acquisition devices include, but are not limited to: the antenna comprises a power supply unit, a wireless detection unit, an algorithm processing unit, an antenna adjusting unit and an antenna.

A power supply unit: for providing electrical power for the operation of other units.

A wireless detection unit: the system is used for detecting the (wireless) signal strength of the image acquisition equipment and the network node and providing the signal strength to the algorithm processing unit.

An algorithm processing unit: and comparing the signal intensity provided by the wireless detection unit with a preset threshold, if the signal intensity is greater than or equal to the threshold, keeping the position of the antenna of the image acquisition equipment unchanged, and if the signal intensity is less than the threshold, providing an adjustment instruction to the antenna adjustment unit.

The antenna adjusting unit drives the antenna to adjust the position through the motor according to the adjusting instruction provided by the algorithm processing unit; the motor includes, but is not limited to, a stepping motor, a dc brush motor, a brushless servo motor, and the like.

Further, a method for adjusting the position of an antenna may be performed in the above application environment, as shown in fig. 3, where the method includes:

step S301, when the connection between the image acquisition equipment and the network node is completed, detecting whether the field range of the image acquisition equipment is changed or not to obtain a first detection result;

the video range is a scene range observable by the image acquisition equipment, the field of view represents the maximum range observable by the lens, and is generally expressed in an angle, and the larger the field of view is, the larger the observation range is. For example, some lenses have a field of view of 50 degrees, and some lenses have a field of view of 58 degrees, and the latter lenses can observe a larger scene range at the same distance than the former lenses.

Further, when detecting whether the field range of the image changes, an image can be acquired when the initialization of the image acquisition device is completed, and then the image is compared with the latest image, if the similarity exceeds the similarity threshold, the field range is judged not to change, otherwise, the field range is judged to change. The latest image may be an image acquired by the image acquisition device under normal conditions, for example, an image acquired by the image acquisition device when a power-off instruction is received, or an image acquired when a restart instruction is received.

Or, when detecting whether the field range of the image changes, it may also be determined whether the field range of the image changes by detecting whether related parameters of the image capturing device change when the initialization of the image capturing device is completed, where the related parameters include, but are not limited to, a shooting angle (which may be measured by a compass), and a focal length. For example, the shooting angle of the image capturing device before power off is "west 268 °" and the focal length is 15mm, and after the image capturing device is powered on, the shooting angle is "west 152 °" and the focal length is 68mm, it can be determined that the field range is changed.

It should be noted that, in addition to the above method, other methods may be adopted to detect whether the image field range changes, and in practical application, the method may be set according to practical requirements, which is not limited in this embodiment of the present invention.

Further, in the embodiment of the present invention, the change of the field range of the image capturing device mainly means that the physical location of the image capturing device is changed under an objective condition, for example, when a certain user originally places a camera in a living room and later places the camera in a bedroom, the field range of the camera is changed. However, the reason that the field range is changed under the subjective condition, for example, the zoom aggregation of the camera is adjusted by the user (because the zoom aggregation is adjusted by the user actively, the camera may be adjusted correspondingly according to the instruction of the user), and the like, is not within the description scope of the embodiment of the present invention.

Step S302, the position of the antenna of the image acquisition device is adjusted based on the first detection result.

In the embodiment of the invention, when the connection between the image acquisition equipment and the network node is completed, whether the field range of the image acquisition equipment is changed or not is detected to obtain a first detection result, and then the position of the antenna of the image acquisition equipment is adjusted based on the first detection result. Like this, whether the physical position through field of view scope detection image acquisition equipment changes, then carries out automatically regulated to the position of antenna according to the testing result to the problem that the position of antenna needs artifical the regulation among the prior art has been solved, the maintenance cost that has significantly reduced has improved maintenance efficiency.

In another embodiment, the steps of a method for adjusting the position of an antenna shown in fig. 3 are described in detail.

specifically, in a normal situation, the image capturing device and the network node are in a connected state, but in an abnormal situation, when the image capturing device and the network node are not connected, it is necessary to establish the connection between the image capturing device and the network node, for example, at least one of the image capturing device and the network node is in a power-off state, or at least one of the image capturing device and the network node is in an initialization state based on a start instruction, a restart instruction, and the like, and of course, other states are also possible, which is not limited in this embodiment of the present invention.

When the connection between the image acquisition equipment and the network node is completed, the image acquisition equipment and the network node can perform data interaction. At this time, whether the field of view range of the image acquisition device changes is detected, so as to obtain a first detection result, wherein the first detection result comprises: no change, or, a change.

Further, when detecting whether the field range of the image changes, an image can be acquired when the initialization of the image acquisition device is completed, and then the image is compared with the latest image, if the similarity exceeds the similarity threshold, the field range is judged not to change, otherwise, the field range is judged to change. The latest image may be an image acquired by the image acquisition device under normal conditions, for example, an image acquired by the image acquisition device when receiving a power-off instruction, or an image acquired when receiving a restart instruction.

If the first detection result is that the physical position of the image acquisition device is not changed, determining that whether the position of the antenna needs to be adjusted is further determined, and if so, determining the position needing to be adjusted and adjusting the antenna to the position; if not, then no adjustment to the position of the antenna is required.

In an embodiment of the present invention, when the first detection result is that no change has occurred, as shown in fig. 4, step S302 includes:

step S401, acquiring N signal strengths of the antenna which are ranked at the front according to the signal strength before the image acquisition equipment is powered off, and determining the maximum first target signal strength in the N signal strengths; n is a positive integer;

step S402, determining a first position corresponding to the first target signal strength;

step S403, adjust the antenna to the first position.

Specifically, when the image capturing device is initialized based on a start instruction, a restart instruction, and the like, power is required to be turned off and then turned on, so that when the image capturing device is turned on and initialized and the field range is not changed, N (N is a positive integer) signal intensities of the antenna before the image capturing device is turned off can be obtained based on the stored signal intensity distribution information, and then the maximum first target signal intensity among the N signal intensities is determined. The signal intensity distribution information is generated and stored by the image acquisition device before power failure, and the specific generation mode will be described in detail later. The signal strength distribution information records the signal strength of the antenna at different positions.

For example, the stored signal strength distribution information records the signal strengths (denoted as S) corresponding to the antennas at 5 positions (denoted as P): P1-S1, P2-S2, P3-S3, P4-S4 and P5-S5, wherein S1> S3> S2> S5> S4, and if N is 3, 3 signal intensities with the top rank are selected from S1-S5: s1, S3, S2, and the maximum value S1 among the 3 signal intensities is taken as the first target signal intensity.

After the first target signal strength is determined, a first position corresponding to the first target signal strength is determined based on the signal strength distribution information, and then the antenna is adjusted to the first position. For example, in the above example, if the position corresponding to S1 is determined to be P1, the antenna may be adjusted to P1.

It should be noted that, in practical application, the value of N may be set according to actual requirements, and this is not limited in the embodiment of the present invention.

If the first detection result is that the physical position of the image acquisition device changes, it can be determined that the physical position of the image acquisition device changes, and at this time, the position of the antenna which needs to be adjusted needs to be further determined, and then the position of the antenna is adjusted.

In an embodiment of the present invention, when the first detection result is changed, as shown in fig. 5, step S302 includes:

step S501, obtaining M signal strengths of the antenna which are ranked at the top before the image acquisition equipment is powered off based on the stored signal strength distribution information, and determining the minimum second target signal strength in the M signal strengths; m is a positive integer;

step S502, detecting whether the second target signal intensity exceeds a first signal intensity threshold value to obtain a second detection result;

step S503, adjusting the position of the antenna based on the second detection.

Specifically, when it is detected that the field of view range changes, M (M is a positive integer) signal strengths of the antennas ranked higher before the image capturing device is powered off may be obtained based on the stored signal strength distribution information, and then a second target signal strength that is the smallest among the M signal strengths may be determined.

For example, the stored signal strength distribution information records the signal strengths of the antenna corresponding to 4 positions: P6-S6, P7-S7, P8-S8 and P9-S9, wherein S7> S8> S6> S9, and if M is 3, 3 signal intensities with the top rank are selected from S6-S9: after S7, S8, and S6, the minimum value S6 among the 3 signal intensities is set as the second target signal intensity.

After the second target signal strength is determined, whether the second target signal strength exceeds the first signal strength threshold value is detected, so that a second detection result is obtained, and then the position of the antenna is adjusted based on the second detection result. Wherein the second detection result comprises: the first signal strength threshold is exceeded or the first signal strength threshold is not exceeded.

It should be noted that, in practical application, the value of M may be set according to practical requirements, and the embodiment of the present invention is not limited to this.

In an embodiment of the present invention, when the second detection result is over, as shown in fig. 6, step S503 includes:

step S601, sequencing the M signal strengths, and determining the maximum third target signal strength in the M signal strengths;

step S602, determining a second position corresponding to the third target signal strength;

step S603, adjust the antenna to the second position.

Specifically, when the second detection result exceeds the first signal strength threshold, the M signal strengths are sorted, a third target signal strength which is the largest of the M signal strengths is determined, a second position corresponding to the third target signal strength is determined based on the signal strength distribution information, and then the antenna is adjusted to the second position. For example, after determining S6, S7, and S8, the three signal strengths are sorted to determine the maximum signal strength S7 as the third target signal strength, then the position corresponding to S7 is determined as P7 based on the signal strength distribution information, and then the position of the antenna is adjusted to P7.

In an embodiment of the present invention, when the second detection result is not more than the second detection result, as shown in fig. 7, step S503 includes:

step S701, acquiring current signal strengths of the antenna at all adjustable positions, and generating current signal strength distribution information based on the current signal strengths;

step S702, determining the maximum current signal intensity in the current signal intensity distribution information, and determining a third position corresponding to the current signal intensity;

step S703, adjust the antenna to a third position.

Specifically, when the second detection result is that the first signal strength threshold is not exceeded, a signal strength search procedure is started for obtaining respective current signal strengths of the antenna at all adjustable positions, and then current signal strength distribution information is generated based on the respective current signal strengths. The adjustable position of the antenna is any position which can be reached by the antenna through automatic adjustment.

For example, an antenna of a certain image capturing device may reach 180 positions through automatic adjustment, and then after a signal strength search procedure is started, current signal strengths corresponding to the 180 positions may be acquired, so as to generate current signal strength distribution information including the 180 current signal strengths. The current signal strength distribution information records each position and the current signal strength corresponding to each position.

And after the current signal intensity distribution information is generated, determining the maximum current signal intensity and a third position corresponding to the maximum current signal intensity, and adjusting the antenna to the third position.

For example, an antenna of a certain image capturing device has 180 adjustable positions, which are respectively P1 to P180, and current signal strengths corresponding to the 180 adjustable positions, which are respectively S1 to S180, are obtained through a signal strength search program, where P1 corresponds to S1, P2 corresponds to S2, and so on, P180 corresponds to S180, and the maximum current signal strength in S1 to S180 is determined as S128 through comparison, then the position P128 corresponding to S128 is taken as a third position, and then the antenna is adjusted to P128.

For convenience of understanding, fig. 8 shows a complete flowchart of each step, wherein the detailed description of each step may refer to the foregoing embodiment, and is not repeated herein to avoid repetition.

In one embodiment of the present invention, as shown in fig. 9, step S701 includes:

step S901, acquiring a zero position of an antenna, and adjusting the antenna to the zero position;

step S902, adjusting the position of the antenna from the zero position until the antenna returns to the zero position again, recording the current signal intensity of the antenna at each adjustable position, and generating the mapping relation between each adjustable position and the corresponding current signal intensity;

step S903, generating current signal strength distribution information based on each current signal strength, and storing the current signal strength distribution information and the mapping relation.

The antenna of the image acquisition equipment is provided with a preset zero point position, the zero point position is used for marking the starting point of the antenna position in the signal strength searching process, then the antenna is adjusted from the zero point position, and the antenna returns to the zero point position after passing through each adjustable position. Wherein the zero position may be any of all adjustable positions. The zero point position is the same as the starting point principle of the playground runway, any point on the runway can be used as the starting point, the runway starts to move along the runway from the starting point, the motion track returns to the starting point to form a circle, and the motion track is formed into a circle as long as the runway starts to move along the runway from the starting point to return to the starting point.

Specifically, when obtaining the current signal strengths of the antenna at all adjustable positions, the null position of the antenna may be obtained first, the antenna is adjusted to the null position, then the position of the antenna is adjusted from the null position, and the adjustment is performed along all adjustable positions until the antenna returns to the null position again, meanwhile, in the process of adjusting the position of the antenna, the current signal strength corresponding to the antenna at each adjustable position is recorded in real time, a mapping relationship between each adjustable position and the corresponding current signal strength is generated, then current signal strength distribution information is generated based on each current signal strength, and the current signal strength distribution information and the mapping relationship are stored, so that the image acquisition device is used after the initialization is completed (step S302).

For example, the antenna of a certain image acquisition device has 10 adjustable positions: P1-P10, wherein P1 is the zero position. Assuming that the current position of the antenna is P6, after the signal strength search procedure is started, first obtaining a zero position P1 of the antenna, then adjusting the antenna position from P6 to P1, at this time obtaining and recording a current signal strength S1 corresponding to the antenna at the P1 position, after the recording is completed, adjusting the antenna from the P1 position to the P2 position, obtaining and recording a current signal strength S2 corresponding to the antenna at the P2 position, and so on until obtaining S1-S10 through the recording, and when the antenna is readjusted back to the P1, the signal strength search procedure is ended. Then P1 is mapped with S1, P2 is mapped with S2, and so on until the mapping of P10 and S10 is completed. Then, current signal strength distribution information is generated based on S1 to S10, for example, as shown in the signal strength distribution diagram of fig. 10, the horizontal axis of the signal strength distribution diagram is the position of the antenna, and the vertical axis is the signal strength. And then storing the signal intensity distribution graph and the mapping relation.

It should be noted that, when mapping the current signal strength with the adjustable position, the current signal strength may be mapped with the corresponding adjustable position immediately after recording one current signal strength, for example, after recording S1, S1 is mapped with P1; or mapping may be performed after all the current signal strengths corresponding to each adjustable position are recorded, for example, after the recording of S1 to S10 is completed, mapping S1 to S10 with P1 to P10, respectively; of course, the mapping may also be performed in other manners, and may be set according to actual requirements in actual applications, which is not limited in this embodiment of the present invention.

Further, the signal strength distribution information may be in a distribution diagram form, or in other forms, and may be set according to actual requirements in practical applications, which is not limited in this embodiment of the present invention.

In an embodiment of the present invention, as shown in fig. 11, the determining of the maximum current signal strength in the current signal strength distribution information in step S903 includes:

step 1101, determining T current signal strengths with the top rank from the current signal strength distribution information; t is a positive integer;

step S1102, detecting whether T current signal strengths exceed a second signal strength threshold;

step S1103, if the T current signal strengths all exceed the second signal strength threshold value, determining the maximum value of the T current signal strengths;

step S1104, if K current signal strengths among the T current signal strengths exceed a second signal strength threshold, determining a maximum value among the K current signal strengths; k is a positive integer less than T;

step S1105, if the T current signal strengths do not exceed the second signal strength threshold, replacing K with T, repeatedly executing the steps of obtaining each current signal strength of the antenna at all adjustable positions, and generating current signal strength distribution information based on each current signal strength; and determining the maximum current signal strength based on the current signal strength distribution information until the maximum current signal strength is determined.

Specifically, after the current signal strength distribution information is generated, T current signal strengths ranked at the top in size (T is a positive integer) may be determined from the current signal strength distribution information, and then it may be detected whether the T current signal strengths respectively exceed the second signal strength threshold.

If the T current signal strengths all exceed the second signal strength threshold, then the maximum value of the T current signal strengths may be determined.

If K (a positive integer less than T) of the T current signal strengths exceed the second signal strength, then the maximum of the K current signal strengths is determined.

If the T current signal strengths do not exceed the second signal strength threshold, it is determined that the T current signal strengths are weak and the connection quality with the network node is poor, and at this time, the signal strength search procedure needs to be restarted, specifically, K is used to replace T, and then steps S701 to S702 are repeatedly executed until the maximum current signal strength exceeding the second signal strength threshold is determined.

As shown in fig. 12, step S1102 includes:

step S1201, determining the maximum value of the T current signal strengths as a first candidate signal strength;

step S1202, detecting whether the first candidate signal strength is less than a second signal strength threshold within a preset time period;

step S1203, if yes, determining a current signal strength one bit behind the first candidate signal strength as a second candidate signal strength, and taking the second candidate signal strength as the current first candidate signal strength;

step S1204, repeatedly performing detection on whether the first candidate signal strength is smaller than a second signal strength threshold within a preset time period; if yes, determining the current signal strength one bit behind the first candidate signal strength as a second candidate signal strength, and taking the second candidate signal strength as the current first candidate signal strength until the T current signal strengths are all detected.

Specifically, when detecting whether T current signal strengths respectively exceed the second signal strength threshold, a maximum value of the T current signal strengths may be determined as a first candidate signal strength, and then it is detected whether the first candidate signal strength is smaller than the second signal strength threshold within a preset time period. The first candidate signal strength may be detected based on an average value of the first candidate signal strength in a preset time period, or may be detected in other manners, and may be set according to actual requirements in actual applications, which is not limited in this embodiment of the present invention.

If so, determining the current signal strength one bit behind the first candidate signal strength, taking the current signal strength as a second candidate signal strength, and adjusting the antenna from the position corresponding to the first candidate signal strength to the position corresponding to the second candidate signal strength. At this time, the second candidate signal strength is regarded as the current first candidate signal strength, and steps S1202 to S1203 are repeatedly executed until all the T current signal strengths are detected.

If not, the position of the antenna is kept unchanged until the preset time period is ended, then the current signal strength one bit behind the first candidate signal strength is determined and is used as the second candidate signal strength, and the position of the antenna corresponding to the first candidate signal strength is adjusted to the position corresponding to the second candidate signal strength. At this time, the second candidate signal strength is regarded as the current first candidate signal strength, and steps S1202 to S1203 are repeatedly executed until all the T current signal strengths are detected.

For example, assuming that T is 5, the 5 current signal strengths determined from the current signal strength distribution information are: s1, S2, S3, S4, S5, the respective current signal strength magnitudes being sorted as: s3> S4> S2> S5> S1. At this time, the position of the antenna is adjusted to the position P3 corresponding to S3, if the average value of S3 within 10 minutes exceeds the second signal strength threshold, the position P4 corresponding to S4 is determined after 10 minutes, if the average value of S4 within 10 minutes exceeds the second signal strength threshold, the position of the antenna is adjusted to the position P2 corresponding to S2, and so on, if the average value of S1 within 10 minutes exceeds the second signal strength threshold, it is stated that all 5 current signal strengths exceed the second signal strength, and at this time, S3 is taken as the maximum current signal strength.

If only three signal strengths of S3, S4 and S2 of S1, S2, S3, S4 and S5 exceed the second signal threshold, S3 is taken as the maximum current signal strength, and K is set to 3, so that T is replaced by K when steps S1101 to S1102 are subsequently executed.

If all of S1, S2, S3, S4, and S5 are smaller than the second signal strength threshold, it indicates that none of the selected T current signal strengths meets the requirement, at this time, K set before is acquired, K is used to replace T, and then steps S1101 to S1102 are executed again.

Further, when it is detected that the physical position of the image acquisition device is not changed, the strongest signal strength can be determined based on the stored signal strength distribution information after the connection between the image acquisition device and the network node is completed, and the antenna can be adjusted based on the strongest signal strength.

Furthermore, when the physical position of the image acquisition device is detected to be changed, a signal strength searching program can be started to acquire the signal strengths corresponding to all adjustable positions of the antenna, signal strength distribution information is generated and stored, the current strongest signal strength is determined based on the generated signal strength distribution information, and the position of the antenna is adjusted to the position corresponding to the current strongest signal strength, so that the connection quality is further ensured.
