Description

Antenna adjustment method and device for multi-input multi-output microwave system

Technical field

The invention belongs to the technical field of microwave antennas, and in particular relates to an antenna adjusting method and device for a multi-input multi-output microwave system.

Background technique

Microwave technology is a wireless transmission method for transmitting data through space. It does not need to lay fiber or cable. It has obvious engineering advantages in cities, remote areas or special areas (such as rivers). Microwave technology is convenient for networking and usage. Flexible, business opening time is short; with the development of microwave technology, the cost of microwave equipment is gradually reduced, so the use of microwave technology is more and more extensive.

Digital microwave (Digital Microwave is a system that transmits PDH (Quasi-Synchronous Digital Hierarchy) and SDH (Synchronous Digital Hierarchy) signals wirelessly. Digital microwave system is generally made up of indoor units (Indoor Unit, IDU) and outdoor unit (Outdoor Unit, ODU) is composed of two parts. The ODU is connected to the indoor unit IDU through an intermediate frequency cable. The ODU is generally installed on an iron tower. The ODU is connected to an antenna, and the radio frequency signal is transmitted through the antenna.

In order to cope with the rapid development of wireless communication transmission bandwidth, such as the next generation of mobile communication technology and mobile Internet, the development of higher wireless transmission capacity system technology is imminent. MIMO (Multiple Input Multiple Output, multiple input and output technology, as a technology that can greatly improve system transmission capacity and signal quality, is considered to be one of the most important technologies for achieving high-speed communication in the future. MIMO technology refers to the technology of spatial diversity and time diversity using multi-transmitting and multi-receiving antennas. It uses discrete multi-antennas, which can effectively decompose the communication link into many parallel sub-channels, thereby greatly increasing the capacity. MIMO technology is beginning to be used in digital microwave systems.

In a MIMO microwave system, each site includes a plurality of ODUs, each of which has an antenna, and the ODUs in the same site are in an indefinite shape, such as a linear arrangement or a square arrangement. The arrangement and placement angle of the antenna directly affects the channel matrix of MIMO, which affects the communication performance of the MIMO microwave system. Therefore, in order to ensure the communication performance of the MIMO microwave system, it is necessary to keep the angles of the antennas on the respective ODUs in the same site consistent, thereby avoiding MIMO channel matrix distortion.

The existing digital microwave communication system is a point-to-point communication system, including a local site and a peer site. There is only one ODU in both sites. When the microwave is deployed, the transmission frequency and the local end of the ODU are configured. The receiving frequency of the site is the same, and the RSSI of the ODU of the local station is detected. (Receive Signal Strength Indicator The received signal strength indication) indicates the value of the port to guide the adjustment of the antenna. Specifically, the voltage value of the RSSI port is read by the voltmeter, and the voltage power comparison table is used to derive the received power, and the antenna is adjusted to maximize the received power value. Similarly, the local station ODU is used as the transmitting end, and the antenna of the opposite station can also be adjusted. However, this adjustment method can only be used to perform signal communication between two stations. The antenna of the local station can be adjusted by receiving the amplitude of the signal sent by the opposite station, and only the adjustment of the transmitting and receiving antennas between the two stations can be supported. . Since this adjustment method is only for the two-site microwave antenna communication system, it cannot be applied to the adjustment of the angles of multiple antennas in the same site in the MIMO microwave system.

In the start of the existing MIMO microwave system, the angle of the antenna is generally adjusted by the existing technology through signal communication between the two stations. When the angle adjustment of all the antennas of the MIMO station is completed, the MIMO signal is debugged. . There may be cases where the angle adjustment of individual antennas is not suitable, which is inconsistent with the designed MIMO channel environment, which causes distortion of the MIMO channel matrix. At this time, we need to adopt a simple and efficient method to find antennas with inconsistent angles.

In the maintenance of the MIMO microwave system, if the performance of the MIMO station is deteriorated, it may be that the angle of an antenna of the MIMO station changes, causing the MIMO channel matrix to be distorted. At this time, we want to find the antenna to be rectified as soon as possible.

Embodiments of the invention

The present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It is understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

In order to explain the technical solution described in the present invention, the following description will be made by way of specific embodiments.

Embodiment 1:

FIG. 1 is a flowchart of a method for adjusting an antenna of a multiple input multiple output microwave system according to a first embodiment of the present invention. For convenience of description, only parts related to the embodiment of the present invention are shown.

The antenna adjustment method of the multiple input multiple output microwave system provided by the implementation of the present invention is applied to a multiple input multiple output microwave system, and the system includes four outdoor units, which are first to fourth units respectively, and only one antenna of the outdoor unit The antenna adjustment method of the other three outdoor units is inconsistent. The antenna adjustment method in this embodiment includes the following steps:

Step S101: Configure the second outdoor unit to be in a transmitting state, configure the first outdoor unit and the third outdoor unit to be in a receiving state, and configure other outdoor units to be in a non-transmitting state, wherein the antenna of the first outdoor unit and the antenna of the second outdoor unit The distance between them is equal to the distance between the antenna of the third outdoor unit and the antenna of the second outdoor unit.

In the MIMO microwave system, the local site and the peer site both include multiple ODUs, one antenna on each ODU, and spatial diversity and time diversity for the local site and the opposite site using discrete multiple antennas. The communication link can be effectively decomposed into many parallel subchannels, thereby greatly increasing the capacity. The precondition for implementing the embodiment is that the antennas of only one of the four outdoor units are inconsistent with the antenna angles of the other outdoor units, and it is necessary to find an inconsistent outdoor unit and adjust the antenna.

In this step, in the same site, such as the local site or the peer site, the distances of adjacent ODUs are equal. Figure 2 shows an arrangement of ODUs. It is assumed that the four ODUs are arranged in a square of 2*2, respectively. It is the first outdoor unit 1, the second outdoor unit 2, the third outdoor unit 3, and the first outdoor unit 4. The antenna of only one of the four ODUs is placed incorrectly. In this embodiment, an ODU is first configured to be in a transmit state, and the two ODUs are configured to receive states. Since the four ODUs are equivalent, it is assumed that the second outdoor unit 2 is in a transmitting state, and second. The outdoor unit 2 and the third outdoor unit 3 are in a receiving state, and the other outdoor units are placed in a non-transmitting state, that is, the fourth outdoor unit 4. The distance between the antenna of the first outdoor unit 1 and the antenna of the second outdoor unit 2 is equal to the distance between the antenna of the third outdoor unit 3 and the antenna of the second outdoor unit 2. Specifically, when the second outdoor unit 2 is configured to be in a transmitting state, the sending frequency and the transmitting power of the second outdoor unit 2 may be configured on the network management device, and the first outdoor unit 1 and the third outdoor unit 3 are configured to be in a receiving state. The step does not limit the working state of the fourth outdoor unit 4, and as long as it is not in the transmitting state, the result of this step is not affected.

Step S102: Determine whether a difference between a microwave signal power value received by the first outdoor unit and a microwave signal power value received by the third outdoor unit is greater than a certain threshold.

Because the main lobe signal of the antenna on the ODU in the same site is toward the opposite end, the ODU will not receive the main lobe signal sent by the ODU antenna at the same site, but the side lobe signal will be uniformly radiated to the surroundings, and the surrounding ODU can receive To the sidelobe signal. Specifically, as shown in FIG. 2, the second outdoor unit 2 is configured to be in a transmitting state, and after the first outdoor unit 1 and the third outdoor unit 3 are configured to receive the state, the antenna of the first outdoor unit 1 and the third outdoor unit 3 The antenna can receive a uniform sidelobe signal radiated by the antenna of the second outdoor unit 2. This embodiment does not limit the size of the transmission power as long as the side lobe signals received by the first outdoor unit 1 and the third outdoor unit 3 are sufficiently large.

Here, the power value of the microwave signal received by the first outdoor unit 1 and the third outdoor unit 3 can be obtained by reading the voltage value of the RSSI interface of the outdoor unit and converting it into a power value. As a preferred implementation manner, the present implementation The network management unit is connected to each outdoor unit. The power value received by the outdoor unit can be uploaded to the network management system through the network. Therefore, the received microwave signal power value is displayed on the network management interface and can be directly read. In this step, it is required to determine whether the difference between the power values of the microwave signals received by the first outdoor unit 1 and the third outdoor unit 3 is greater than a certain threshold, and the threshold is related to the configured transmit power. In the case of normal radiation, the threshold is Can be set to 5dB.

Step S103: If the determination is no, the antenna of the fourth outdoor unit is adjusted such that the antenna angle of the fourth outdoor unit and the other outdoor units are the same.

Since the distance between the antenna of the first outdoor unit 1 and the antenna of the second outdoor unit 2 and the distance between the antenna of the third outdoor unit 3 and the antenna of the second outdoor unit 2 are equal, if the first outdoor unit 1 and The difference between the microwave signal power values received by the third outdoor unit 3 through the antenna is less than the threshold, that is, within a certain range, such as between 0 and 5 dB, indicating the antenna of the first outdoor unit 1 and the third outdoor unit. The arrangement angle of the antenna of the third outdoor unit 2 is the same as that of the second outdoor unit 2, and the antennas of the first outdoor unit 1, the second outdoor unit 2, and the third outdoor unit 3 are not required to be adjusted, which is in accordance with the microwave design. It is required that the antenna angle of the fourth outdoor unit 4 is not correct because the antenna angles of the one of the four outdoor units are inconsistent. Therefore, in this step, the antenna of the fourth outdoor unit needs to be adjusted, so that the fourth outdoor The unit has the same angle as the antenna of other outdoor units.

The antenna adjustment method of the MIMO system provided by this embodiment considers an ideal situation. The angles of the antennas of the three outdoor units are exactly the same. In this case, only the antenna of another outdoor unit can be adjusted. . In this embodiment, the power values of the side lobe microwave signals received by the outdoor unit are used to determine whether the antenna angles are consistent. This method is simple and efficient, and is convenient for quickly finding an outdoor unit with inconsistent antenna angles in the microwave deployment.

Embodiment 2:

FIG. 3 is a flowchart of a method for adjusting an antenna of a multiple input multiple output microwave system according to a second embodiment of the present invention. For the convenience of description, only parts related to the embodiment of the present invention are shown.

The implementation basis of the embodiment is that the multi-input multi-output microwave system includes four outdoor units, which are respectively the first unit to the fourth unit, and only one of the antennas of the outdoor unit has an antenna angle different from that of the other three outdoor units. The antenna adjustment method in the embodiment includes the following steps:

Step S301, configuring the second outdoor unit to be in a transmitting state, configuring the first outdoor unit and the third outdoor unit to be in a receiving state, and configuring other outdoor units to be in a non-transmitting state, wherein the antenna of the first outdoor unit and the antenna of the second outdoor unit The distance between the distance is equal to the distance between the antenna of the third outdoor unit and the antenna of the second outdoor unit;

Step S302: Determine whether a difference between the microwave signal power value received by the first outdoor unit and the microwave signal power value received by the third outdoor unit is greater than a certain threshold.

The above steps S201 and S202 are the same as steps S101 and S1 02 in the first embodiment, and are not described herein again.

Step S303: If the determination is no, the antenna of the fourth outdoor unit is adjusted such that the antenna angle of the fourth outdoor unit and the other outdoor units are the same.

When it is determined that the difference between the microwave signal power value received by the first outdoor unit 1 and the microwave signal power value received by the third outdoor unit 3 is within the threshold range, indicating the first outdoor unit to the first The antenna angles of the three outdoor units are the same. In this case, the angle of the antenna of the fourth outdoor unit needs to be adjusted so as to be consistent with the antenna angles of other outdoor units. As a specific preferred antenna adjustment scheme, the method for adjusting an antenna of a fourth outdoor unit is specifically as follows:

S3031: The first outdoor unit is configured to be in a transmitting state, the second outdoor unit and the fourth outdoor unit are configured to be in a receiving state, and the other outdoor units are configured to be in a non-transmitting state;

S3032: Adjust an antenna of the fourth outdoor unit such that a difference between a microwave signal power value received by the second outdoor unit and a microwave signal power value received by the fourth outdoor unit is within the threshold range.

In the embodiment, when the angle of the fourth outdoor unit is adjusted, the fourth unit is configured to receive the state, and the other two outdoor units that have been adjusted in the angle are configured as the transmitting state and the receiving device, and the fourth outdoor unit is adjusted. The antenna is such that the difference between the received microwave signal power values of the two outdoor units in the receiving state is within the threshold range, so that the antenna angle of the fourth outdoor unit is consistent with the antenna angles of the other outdoor units.

Step S304, if the determination is yes, configuring the first outdoor unit to be in a transmitting state, configuring the second outdoor unit and the fourth outdoor unit to be in a receiving state, and configuring other outdoor units to be in a non-transmitting state, wherein the antenna of the second outdoor unit The distance between the antenna and the antenna of the first outdoor unit is equal to the distance between the antenna of the fourth outdoor unit and the antenna of the first outdoor unit.

If the difference between the microwave signal power value received by the first outdoor unit and the microwave signal power value received by the third outdoor unit is greater than the threshold, indicating that an outdoor unit exists in the first outdoor unit to the third outdoor unit The angle of the antenna is inconsistent with that of the other antennas, and the angle of the antenna of the fourth outdoor unit is correct. Therefore, it is necessary to continue to determine the outdoor unit in which the antenna angles of the first outdoor unit to the third outdoor unit are inconsistent. The outdoor unit is in a transmitting state, and the second outdoor unit and the fourth outdoor unit are configured to be in a receiving state.

Step S305: determining whether a difference between a microwave signal power value received by the second outdoor unit and a microwave signal power value received by the fourth outdoor unit is greater than a certain threshold;
