Description

Technical Field

[0001] This invention relates to the field of wireless communication technology, and is a wireless communication device, control method, terminal equipment, and storage medium suitable for long-distance communication. Background Technology

[0002] Wireless communication technology primarily utilizes the free propagation of electromagnetic waves in space to achieve communication. It has risen to become one of the core tools in the modern communication field, evolving through several stages from early radio wave transmission to contemporary high-frequency broadband networks. In long-distance communication, wireless communication technology, by eliminating the need for physical cables, greatly simplifies and expands network architecture, an advantage particularly evident in complex terrain or remote areas. Furthermore, compared to wired technologies, wireless communication exhibits greater flexibility and scalability, more readily adapting to evolving and diverse communication needs.

[0003] In diverse environments, network transmission needs vary significantly, directly impacting the efficiency and reliability of information exchange and data transmission across various sectors. The oil and mining industry, in particular, is characterized by complex geographical environments, vast operating areas, and harsh working conditions. Currently, industrial-grade bridge technology supports communication distances up to 20 kilometers and boasts bandwidth capabilities of up to 4804 Mbps. This feature perfectly matches the characteristics of the operating area, enabling long-distance, high-bandwidth communication. However, the directional antenna radiation angle of the bridge is limited, requiring operators to manually adjust the alignment angle between the bridge and the base station antennas on-site to ensure effective signal transmission. When the bridge's directional antenna is outside the base station's antenna radiation range, the signal strength fluctuates, or even drops completely.

[0004] In the prior art, invention patent CN106912083A discloses a routing method for wireless sensor networks suitable for large-scale outdoor environments. However, when the directional antenna is not aligned, leading to a decrease in signal quality, the routing method may need to select a longer path or more relay nodes to ensure data transmission, thereby reducing routing efficiency. Invention patent CN103167598B discloses a long-distance communication method and device. This method increases the communication coverage in scenarios such as ground-to-air communication systems, but limitations in communication connectivity still exist in the outdoor environments of the oil and mining industries. Summary of the Invention

[0005] This invention provides a wireless communication device, control method, terminal equipment, and storage medium suitable for long-distance communication, overcoming the shortcomings of the prior art. It can effectively solve the communication problems of existing wireless communication devices in complex environmental conditions such as long-distance field operations in the oil and mining industry.

[0007] The second technical solution of the present invention is achieved through the following measures: a wireless communication control method suitable for long distances, comprising: By analyzing the signal curve, we can revert to the optimal signal point and save the azimuth and pitch angles of the optimal point so that we can quickly restore the optimal signal point position when the boom is retracted due to wind. A quality structure array is established. The array is scanned and sorted across the entire range from the start of the connection signal to the disappearance of the connection signal. A sorting algorithm is used to find the point with the best signal quality. Then, the pan-tilt unit rotates to the point with the best signal quality to conduct communication.

[0008] The following are further optimizations and / or improvements to the second technical solution of the above invention: The scanned signal quality curve can be fitted to a quasi-normal distribution function, and the extreme points of this function distribution can be used to determine the signal strength.

[0009] The system can sort and calculate all recorded signal quality arrays, and only record points with negative slope signs to quickly find the best signal point, thereby controlling the rapid adjustment of the attitude of the wireless communication device.

[0010] By monitoring and analyzing the changing trends of signal strength in real time, the location of the signal point with the best signal quality can be accurately identified, enabling wireless communication devices to quickly adjust their orientation, including antenna angle and direction, and dynamically optimize the signal transmission path.

[0011] When extreme weather conditions are detected, the operation of raising and lowering the communication pole can be triggered.

[0012] The third technical solution of the present invention is achieved through the following measures: a terminal device, including a memory and a processor, wherein the memory stores a program that can run on the processor, and the processor executes the program to implement the above-mentioned wireless communication control method applicable to long distances.

[0013] The fourth technical solution of the present invention is achieved by the following measures: a storage medium storing one or more programs, which can be executed by one or more processors to realize the above-mentioned wireless communication control method applicable to long distances.

Targeting high-cost industries like oil drilling, this invention effectively solves key network communication problems at the lowest cost. Compared to traditional solutions that require numerous relay stations or rely on cumbersome manual adjustments, this invention employs an intelligent adjustment strategy, maintaining not only efficient and stable communication quality but also significantly reducing hardware investment and subsequent maintenance costs, bringing tangible economic benefits to oil companies.

It solves the problem of directional antennas on wireless bridges finding the radiation range of directional antennas on base stations, enabling automatic calibration of long-distance wireless communication devices in the field. Attached Figure Description

[0015] Figure 1 This is a signal quality scan curve of a wireless communication device according to an embodiment of the present invention. Detailed Implementation

[0016] The present invention is not limited to the following embodiments, and specific implementation methods can be determined according to the technical solutions and actual conditions of the present invention.

[0017] The present invention will be further described below with reference to embodiments: Example 1: The wireless communication device suitable for long distances includes an electric pan-tilt unit, a high-precision three-dimensional electronic compass module, a multi-functional meteorological monitor, and a network bridge system; Among them, the electric pan-tilt unit is used to support and securely install the high-precision electronic compass module, multi-functional meteorological monitoring instrument and network bridge system, and intelligently control the lifting operation of the device to adapt to severe weather conditions, while precisely adjusting the device's attitude to optimize the radiation range for finding and locking base station signals. Among them, the high-precision three-dimensional electronic compass module has high-precision measurement capabilities, which is used to acquire the azimuth and elevation angle information of the current device in real time, and calculate the accurate local geodetic coordinates, providing key data for the precise positioning of the device; The multi-functional meteorological monitor integrates sensors for temperature, humidity, air pressure, wind speed, and wind direction to comprehensively monitor current environmental meteorological conditions. Upon detecting extreme weather conditions, the monitor triggers a motorized pan-tilt unit to raise and lower the communication pole, ensuring the physical safety of the communication equipment and maintaining communication continuity. The bridge system is designed for efficient and stable communication with the base station, possessing anti-interference capabilities and long-distance transmission capabilities. It ensures a high-quality communication link under complex electromagnetic environments and long-distance transmission conditions, improving the reliability and efficiency of wireless communication. In this embodiment, the bridge system is a high-performance industrial-grade bridge system.

[0018] In practical applications, the electronic compass acquires the transmission direction (far-end azimuth), horizontal direction angle (far-end horizontal angle), elevation angle, and geodetic coordinates of the remote base station's transmitting antenna. A high-precision three-dimensional electronic compass mounted on the pan-tilt unit acquires the current azimuth, elevation angle, and geodetic coordinates of the wireless communication device. The point azimuth and elevation angles between the near and far ends are obtained using the geodetic coordinates; this point elevation angle serves as the initial elevation angle of the pan-tilt unit.

[0019] In this embodiment, the data frame format of the electronic compass and Maike Sensing is shown in Table 1. The serial port standard is as follows: 8 data bits, 1 stop bit, no parity, default speed 9600; data format: hexadecimal; identifier: fixed at 0x68; data length: the length from the data length to the checksum (including the checksum); address code: the address of the acquisition module, default is 0x00; data field: varies according to the different contents and lengths of the command word; checksum: the sum of data length, address code, command word and data field, without considering carry.

[0020] Based on the far-end azimuth, horizontal angle, and elevation angle, the point azimuth and elevation angles are used to determine if an impossible connection exists. If a connection is impossible, an alarm is triggered, and a connection failure message is sent. If a connection is possible, the minimum azimuth, minimum elevation, maximum azimuth, and maximum elevation angles required for the local PTZ are calculated, and the optimal estimated azimuth and elevation angles are pre-calculated. The minimum azimuth angle is also the difference azimuth and elevation angle at this point. If there is no far-end azimuth data for the base station, and the near-end PTZ is arbitrarily adjusted: Near-far azimuth angle = Near-far azimuth angle + Near-far horizontal coverage angle / 2; The near-far azimuth angle ends = MIN[azimuth angle obtained from compass - (near-far azimuth angle + near-far horizontal coverage angle / 2), azimuth angle obtained from compass - (near-far azimuth angle - near-far horizontal coverage angle / 2)] - starting to be considered close to the signal reception starting point, until (near-far azimuth angle - near-far horizontal coverage angle / 2).

[0021] Data recording and signal connection establishment are performed with a 5-second establishment time. Rotation steps begin in 0.1-degree increments, meaning the total number of steps is the near-end horizontal coverage angle multiplied by 10, with each step taking 5 seconds. Alternatively, scanning can be performed in 1-degree increments, with a 10-second connection establishment time. The signal strength, signal quality, and signal-to-noise ratio are recorded for each step. After the scan ends, the optimal value is retrieved, and a second scan is performed using the azimuth angle recorded by the electronic compass at that time, moving 5 degrees to the left and right, with each step taking 0.1 degrees. The scanned values ​​are recorded. Finally, the maximum and minimum values ​​are located and recorded, and scanning is performed using the azimuth angle recorded by the electronic compass, moving 1 degree to the left and right, with each step taking 0.1 degrees. When the maximum value is reached, the scan stops or the position is directly rotated to the azimuth angle in the structure array.

[0022] In this embodiment, to prevent mechanical damage to the device caused by rapid rotation of the electric gimbal, this invention proposes a gimbal rotation control algorithm. Several speeds from the gimbal speed table are selected and recursively calculated to find the optimal rotation speed for reaching the optimal signal position. In the coarse adjustment stage, the gimbal rotation speed is adjusted first, starting with the pitch angle. The pitch adjustment algorithm uses a difference angle; if it is less than or equal to 1 degree, no adjustment is made; if it is greater than 1 degree, the speed of gimbal speed number 7 (1 degree per second) is used to adjust it to the desired position. Then, the horizontal angle is adjusted. The pitch is adjusted to the corresponding angle, and then the horizontal rotation is started, adjusting the angle to achieve the optimal horizontal value. The horizontal and pitch angles can be adjusted quickly. The pitch angle at the far end is preset to a downward tilt of 5 degrees, and the gimbal at the near end rotates directly to the calculated pitch angle for the initial search. Take the current azimuth angle of the electronic compass. The difference angle = electronic compass azimuth angle - near / far azimuth angle. A positive value indicates right turn, and a negative value indicates left turn. Multiply the difference angle by 100 to convert it to 0.1 degrees. Then divide the difference angle by the value of 10 seconds. Search the speed control table for the speed number closest to this value and reduce it by three levels. Rotate for 10 seconds, then repeat the difference calculation. When the speed level is less than or equal to 7 (i.e., the rotation speed is 1 degree per second), start recording the connection quality data for each time to search for the optimal communication quality angle. Repeat the above difference calculation, and directly use speed level 5 (0.4 degrees per second) to calculate the required duration and control the rotation. When the timer expires, calculate again. If the difference angle is less than 1 degree (i.e., multiply the difference angle by 100, which equals 0.1 degrees), multiply the current angle by 100 to get 0.1 degrees for calculation.

[0023] Using the gimbal rotation speed meter, the rotation speed is a near-integer value ending in 5, with a 6-digit floating-point interval between any two numbers. This makes mathematical calculations relatively convenient for any angle difference. Imagine the speed range is reduced by six levels, meaning the theoretical speed is calculated at 10-second intervals. Then, find the largest number ending in 5 in the gimbal speed meter, use that number to calculate the rotation time, and round it down.

[0024] If the angle difference is 224 degrees, the closest speed value from the gimbal speed table is 17.125 degrees / second. The time required at this speed is 13.08029 seconds. Assuming the timer is set to 13 seconds, the rotation angle after 13 seconds at this speed is 222.625 degrees, which is 1.375 degrees different from the target rotation angle.

[0025] If the angle difference is 170 degrees, the closest speed value from the gimbal speed table is 11.75 degrees / second. At this speed, the required time is 14.468085 seconds. Assuming the timer is set to 14 seconds, at this speed, the rotation angle after 14 seconds is 164.5 degrees, which is 5.5 degrees different from the target rotation angle.

[0026] If the angle difference is 116 degrees, the closest speed value from the gimbal speed table is 6.375 degrees / second. At this speed, the required time is 18.19607843 seconds. Assuming the timer is set to 18 seconds, at this speed, the rotation angle after 18 seconds is 114.75 degrees, which is 1.25 degrees different from the target rotation angle.

[0027] If the angle difference is 6.3 degrees, then the closest speed value from the gimbal speed table is 1 degree / second. Therefore, the time required at this speed is 6.3 seconds. Assuming the timer is set to 6 seconds, the rotation angle after 6 seconds at this speed is 6 degrees, and the difference between this and the target rotation angle is 0.3 degrees.

[0028] Therefore, the maximum difference in rotation angle from the target is 5.5 degrees. Communication distances of 5 km, 10 km, and 20 km are designed between the base station's wireless bridge and the well site wireless communication device. Calculations are then performed based on deviations of 3 degrees and 5 degrees from the straight-line connection point of the base station's wireless bridge.

[0029] When the deviation is 3 degrees over 5 kilometers: sin(3)X5X1000=261.67978 meters, when the deviation is 5 degrees over 5 kilometers: 435.7787 meters; when the deviation is 3 degrees over 10 kilometers: 523.35956 meters, when the deviation is 5 degrees over 10 kilometers: 871.5574 meters; when the deviation is 3 degrees over 20 kilometers: 1046.7191 meters, when the deviation is 5 degrees over 20 kilometers: 1743.11485 meters.

[0030] The deviation increases with distance, exceeding 1 kilometer at distances over 20 kilometers. Even at 5 kilometers, the deviation is already close to 300 meters. Therefore, a signal search angle of ±3 degrees can be considered. The angle difference for gimbal rotation is retained at 3 degrees before calculating rotation speed and time, as terrain and other environmental factors effectively reduce the optimal signal quality when searching for targets.

[0031] The pan-tilt unit (PTZ) is then fine-tuned within ±3 degrees. On one hand, upon reaching approximately 3 degrees, the PTZ rotation is stopped for 10 seconds to check the signal connection of the nearby wireless bridge. If there is no connection, the PTZ is rotated in 0.4-degree increments (rotation speed 5). If the target adjustment angle is not yet reached, the increments are increased to accelerate the adjustment until a signal connection is detected on the wireless bridge. On the other hand, upon reaching approximately 3 degrees, the PTZ rotation is stopped for 10 seconds to check the wireless bridge signal connection, then the PTZ is rotated in 0.1-degree increments. Each increment is followed by a 5-second pause to check and record the signal quality. Each 0.1-degree change takes 6 seconds. With 60 checkpoints (±3 degrees, or 6 degrees in total), each checkpoint takes 6 seconds, totaling 360 seconds (6 minutes). This is the maximum time required, considering that even at a theoretically optimal alignment angle of ±3 degrees, the signal quality is not yet at its best. Simultaneously, the signal quality information of continuous points is saved, and the slope is calculated and saved sequentially for the two points before and after.

[0032] exist Figure 1 In the signal curve diagram shown, if the slope is negative for 5 consecutive points, it can be considered as monotonically decreasing. The 5 points are used to consider that 1, 2, 3, 5, 7, and 11 are prime numbers. There may be unstable signal between points 1 and 5. If it is monotonically decreasing, stop the current rotation direction and change to the opposite direction to search for signal quality.

[0033] If five consecutive points show a positive slope, it can be considered monotonically increasing, and the gimbal continues recording the detected signal quality in the current direction. If, during the monotonically increasing process, five consecutive points show a negative slope, it can be considered a normal distribution. At this point, the gimbal rotation angle has exceeded the angle of the optimal signal quality position. The recorded slope array can then be checked to find the slope closest to 0, indicating the optimal signal quality position. While the slope of a normal distribution is 0, in reality, it's impossible to find a point with a slope of 0. The characteristic of a normal distribution is precisely the transition from monotonically increasing to monotonically decreasing, so the sign of the slope changes from positive to negative between two adjacent points in one process. This process adjusts the gimbal to the correct position in one go, without needing to sort or search the recorded array, thus enabling the wireless communication device to quickly adjust its posture to the optimal signal state.

[0034] This embodiment creatively designs a high-performance long-distance wireless communication device. This device possesses powerful signal transmission and reception capabilities, effectively overcoming signal attenuation problems under complex terrain and harsh weather conditions, ensuring the stability and reliability of data communication in field operations such as oil drilling. This embodiment targets high-cost industries such as oil drilling, effectively solving key network communication issues at the lowest cost. Compared to traditional solutions that require numerous relay stations or rely on cumbersome manual adjustments, this embodiment employs an intelligent adjustment strategy, maintaining not only efficient and stable communication quality but also significantly reducing hardware investment and subsequent maintenance costs, bringing tangible economic benefits to oil companies. This embodiment focuses on the oil and mining industry, solving the problem of how to achieve efficient and stable long-distance wireless communication transmission in this sector. A wireless communication device is designed using an electric pan-tilt unit, a high-precision electronic compass, an outdoor industrial-grade network bridge, and a multi-functional weather instrument. An attitude control method for the wireless communication device is proposed, solving the problem of the wireless network bridge's directional antenna finding the radiation range of the base station's directional antenna, and achieving automatic calibration of the long-distance wireless communication device in the field.

[0035] Example 2: This example provides a wireless communication control method suitable for long distances, including: By analyzing the signal curve, we can revert to the optimal signal point and save the azimuth and pitch angles of the optimal point so that we can quickly restore the optimal signal point position when the boom is retracted due to wind. When the terrain is complex, under full far-end radiation angle conditions, as the scanning of the far-end wireless bridge signal occurs, the signal quality fluctuates within the signal radiation range due to various terrain factors as the rotation angle changes. Therefore, in this embodiment, a quality structure array is established, and the array is scanned and sorted across the entire range from the initial connection signal to its disappearance. A sorting algorithm is used to find the point with the best signal quality, and then the pan-tilt unit rotates to the point with the best signal quality for communication.

[0036] However, scanning the entire signal range takes a long time, potentially several hours. To address this, in this embodiment, the scanned signal quality curve is fitted to a near-normal distribution function, and the extreme points of this distribution are used to determine signal strength. Whether monotonically increasing or decreasing, if the curve is not near an extreme point, the product of the slopes is positive. Therefore, when the sign of the slope changes, the position of the last value taken is the inflection point of the normal distribution slope. In this embodiment, the receiveable signal quality is as follows: Figure 1As shown, this curve exhibits a normal distribution overall. In this embodiment, in order to enable the PTZ to adjust quickly and find the best signal point of the network, the present invention divides the signal quality curve into a monotonically increasing curve, a monotonically decreasing curve, and a normally distributed curve. The causes of these three curves are as follows: (1) Monotonically increasing curve. Regardless of the installation direction of the remote wireless bridge and the terrain, the signal quality received during the rotation of the PTZ becomes better and better, and gets closer and closer to the optimal signal quality directional angle. (2) Monotonically decreasing curve. The installation direction of the remote wireless bridge is not directly facing the near end, and there is a certain angular deviation. At the same time, due to the influence of the terrain, the PTZ has missed the optimal alignment point when it rotates, causing the signal quality to become worse and worse when the PTZ is theoretically close to the alignment point. At this time, it is necessary to immediately change the rotation direction and rotate the PTZ at a certain rotation speed to find the optimal signal quality directional angle. (3) Normal distribution curve. The curve changes from a monotonically increasing curve to a monotonically decreasing curve, indicating that the PTZ missed the optimal alignment angle during the rotation and needs to be rotated in the opposite direction to the optimal angle. In this embodiment, the normal distribution curve is key to finding the optimal angle value.

[0037] In this embodiment, the signal quality arrays of all records are sorted and calculated, and only the points with negative slope signs are recorded to quickly find the best signal point, thereby controlling the rapid adjustment of the attitude of the wireless communication device.

[0038] In this embodiment, by monitoring and analyzing the changing trend of signal strength in real time, the location of the signal point with the best signal quality is accurately identified, enabling the wireless communication device to quickly adjust its posture, including antenna angle and direction, and dynamically optimize the signal transmission path. This can significantly improve communication efficiency and quality.

[0039] In this embodiment, when extreme weather conditions are detected, the multi-functional weather monitor triggers the electric pan-tilt assembly to raise and lower the communication pole, thereby ensuring the physical safety of the communication equipment and the continuity of communication.

[0040] In this embodiment, the general formula for estimating wind pressure based on wind speed is used. The density of air and the acceleration due to gravity vary with latitude and altitude. Theoretically, at the same wind speed and temperature, the wind pressure is lower on plateaus than on plains. Based on Table 2, wind speed and wind force level, taking a gale of force 8 as an example, and using the maximum value of 20.7 m / s, we get... According to the parameters of an industrial-grade wireless bridge, its area is 0.0576m². 2 wind resistance The motorized pan-tilt unit has torque parameters of 23 N·m for pitch and 12.18 N·m for horizontal. With the motorized pan-tilt reaching 100mm from the top of the platform, and considering the outdoor wireless bridge specifications, the distance from the pan-tilt to the bridge's center of gravity is approximately 250mm, or 0.25 meters. Therefore, the pitch torque of this motorized pan-tilt is sufficient to support the operation of the industrial wireless bridge under gale-force winds (level 8).

[0041] This embodiment proposes an adaptive adjustment strategy based on the slope of a fitted signal quality curve. By monitoring and analyzing the changing trend of signal strength in real time, this strategy can accurately identify the location of the signal point with optimal signal quality. This intelligent adjustment mechanism enables wireless communication devices to quickly adjust their orientation, including antenna angle and direction, thereby dynamically optimizing the signal transmission path and significantly improving communication efficiency and quality. This embodiment targets high-cost industries such as oil drilling, effectively solving key network communication problems in a cost-effective manner. Compared to traditional solutions that require adding a large number of relay stations or rely on cumbersome manual debugging, this embodiment adopts an intelligent adjustment strategy that not only maintains efficient and stable communication quality but also significantly reduces hardware investment and subsequent maintenance costs, bringing tangible economic benefits to oil companies.
