Description

Technical Field

[0001] The present application relates to the technical field of repeater deployment, and in particular to an intelligent deployment method and system for repeaters based on the Internet of Things. Background Art

[0002] A repeater is a wireless signal relay product, mainly used for signal amplification and transmission in telecommunication networks to enhance signal coverage and signal quality. A repeater receives signals from base stations or transmitters, amplifies them, filters them, and then retransmits them, thereby achieving extended signal coverage. It is crucial to install and configure repeater equipment into the communication network according to certain plans and designs. This process aims to solve the signal coverage problem in a specific area through the signal amplification function of the repeater, and improve the overall coverage quality and user experience of the network. At present, the deployment of repeaters is usually based on the isolation and gain of the antenna. Since different users have different requirements for data transmission, the deployment of repeaters based on the isolation and gain of the antenna does not fully improve the user experience. Therefore, there are still defects in improving the user experience through the deployment of repeaters. Summary of the invention

[0051] Preferably, if the number of data areas covered by the repeater is not one, the step of obtaining the speed requirement values ​​and speed safety values ​​of all covered data areas to obtain the advantageous deployment position is specifically as follows:

[0052] Obtain speed demand values ​​and speed safety values ​​of all covered areas, and select the highest speed demand value and speed safety value as reference speed demand value and reference speed safety value respectively;

[0073] Figure 2 It is a module connection diagram of an embodiment of the repeater intelligent deployment system based on the Internet of Things of the present invention. DETAILED DESCRIPTION

[0074] Below is a combination of the embodiments and Figure 1-Figure 2 The present invention is further described in detail, but the embodiments of the present invention are not limited thereto.

[0075] The present invention discloses a method for intelligent deployment of repeater stations based on the Internet of Things, which specifically includes the following steps:

[0076] Step S1, obtaining the deployment range of the repeater, dividing the deployment range into regions according to the main data types transmitted, and obtaining multiple data regions.

[0077] The types of data transmitted in different areas are different. For example, hospitals mainly transmit patient information, scientific research institutions mainly transmit scientific research data, and community users transmit personal privacy data.

[0078] Step S2, obtaining the distance between the data area and the base station, and determining the number range of repeater stations around the data area according to the antenna isolation of the repeater stations.

[0079] Step S3, obtaining the communication demand conditions of the main data types in the data area, and determining the initial deployment number of repeaters in the data area according to the communication demand conditions and the range of the number of repeaters.

[0080] Step S4, obtaining the coverage of the repeater, forming a repeater layout diagram according to the initial deployment quantity of all data areas, and obtaining the initial deployment position of the repeater.

[0081] Step S5, adjusting the initial deployment position according to the base station signal strength to obtain a dominant deployment position.

[0082] Step S6, obtaining the environmental conditions of the advantageous deployment position, adjusting the advantageous deployment position according to the environmental conditions and obtaining the optimal deployment position.

[0083] In actual use, repeater deployment refers to the process of installing and configuring repeater equipment into the communication network according to a certain plan and design. This process aims to solve the signal coverage problem in a specific area through the signal amplification function of the repeater, and improve the overall coverage quality and user experience of the network. However, different data transmission requirements are different. Uniform deployment according to antenna isolation will form the same user experience in different areas and different users, but it cannot meet the communication needs of users in all areas very well. This not only consumes a lot of resources but also does not produce good results, resulting in a waste of resources. For example, in some areas, such as scientific research areas, data focuses more on security. Some data is more important and cannot be fault-tolerant, so more attention is paid to the stability of data transmission. For some timely data, such as stock trading, the data changes in real time, so what is more needed is the data transmission speed. A slightly slower speed can easily lead to transaction failure.

[0084] The steps of obtaining the distance between the data area and the base station and determining the number of repeaters around the data area according to the antenna isolation of the repeaters are as follows:

[0085] Step S21, obtaining the base station signal strength of the data area, and obtaining the minimum number of repeaters around the data area according to the base station signal strength.

[0086] Step S22, obtaining the area size of the data area, and obtaining the maximum number of repeaters in the data area according to the antenna isolation distance of the repeaters.

[0087] Step S23: if the maximum number of repeaters is not less than the minimum number of repeaters, a range of the number of repeaters is obtained according to the maximum number of repeaters and the minimum number of repeaters.

[0088] Step S24: If the maximum number of repeaters is less than the minimum number of repeaters, the range of the number of repeaters is 0-the minimum number of repeaters.

[0089] In actual use, in order to prevent self-excitation and interference of signals and ensure the stability and performance of the communication system, antenna isolation is required for repeaters. The number of repeaters that can be deployed is determined based on the existing isolation calculation method, because too many repeaters will cause self-excitation. In order to achieve a wide coverage range and strong coverage signal, too few repeaters will not meet the signal requirements. Therefore, the number of repeaters should not be too many or too few. The number range of repeaters is obtained based on the isolation and signal requirements of the repeaters, so as to facilitate the subsequent deployment of repeaters.

[0090] The steps of obtaining the communication demand of the main data types in the data area and determining the initial deployment number of repeaters in the data area according to the communication demand and the range of the number of repeaters are as follows:

[0091] Step S31, extracting the confidentiality BJ of the main data types, and finding the security requirement value AX according to the association curve between the preset confidentiality BJ and the security requirement value of data transmission.

[0092] Step S32, obtaining the user's speed requirement value AS for the main data type.

[0093] Step S33, extracting historical data from the main data types, and obtaining an average interval duration CC of continuous use of the historical data.

[0094] Step S34, statistics the severity of the consequences caused by unstable transmission CY, according to the stability demand correlation function The stable demand value AW is calculated, where , is the scaling factor and is greater than 0.

[0095] Some data needs to be transmitted stably, such as video and voice. If the transmission is unstable, it will cause freezes. If some monitoring data is not transmitted continuously, it will also affect the monitoring results. The shorter the average interval between continuous use of data, the faster the transmission is needed. The more serious the consequences of unstable transmission, the more stable transmission is needed. For example, unstable video transmission will only result in a poor viewing experience, and unstable GPS positioning during rescue can easily lead to rescue failures and loss of life.

[0096] Step S35, according to the deployment quantity correlation function The estimated deployment quantity ST is calculated, where , is the scaling factor and is greater than 0.

[0097] Step S36: If the estimated deployment quantity is within the range of the number of repeater stations, the estimated deployment quantity is used as the deployment quantity of repeater stations.

[0098] Step S37: If the expected deployment number is not within the repeater number range, the number closest to the expected deployment number in the repeater number range is used as the initial deployment number of repeaters.

[0099] In actual use, data with high confidentiality requires more security of data transmission, so the security requirement value of the user is obtained according to the confidentiality of the data. Data transmission security requirements usually do not directly affect the number of repeater deployments, but the data speed requirements and data stability requirements are related to the number of deployments. When the data transmission speed requirements are high, the number of repeater deployments needs to be increased to ensure the continuity and strength of the signal, thereby reducing signal attenuation and transmission delay. Especially in long distances or complex terrain conditions, increasing the number of repeaters can more effectively relay and amplify the signal to meet the needs of high-speed data transmission. To ensure the stability of data transmission, the number of repeater deployments needs to be appropriately increased to form redundant coverage and backup links. In this way, even if a repeater fails or the signal is interrupted, other repeaters can continue to provide stable signal transmission services. Therefore, the number of repeaters required in the area is determined according to the data speed requirements and stability requirements. When the required repeater is not within the number range, the closest data is selected as the number of deployments. For example, the number of repeaters ranges from 3 to 5. According to the signal requirements, 6 repeaters need to be installed. Exceeding the number range will easily cause self-excitation and interference, which will have a significant impact on data transmission. Therefore, 5 repeaters are selected as the number of deployment. If only 1 repeater is required, it will be difficult to meet the signal requirements, so 3 repeaters are selected as the number of deployment.

[0100] The steps for extracting the confidentiality BJ of the main data types are as follows:

[0101] Step S311, extracting historical data of the main data types, and determining whether the historical data is public data. If the historical data is public data, the confidentiality level BJ=0.

[0102] Step S312: If the historical data is not public data, the number of visitors BF is obtained according to the access permission.

[0103] Step S313, obtaining the average loss BS caused by the leakage of historical data, and determining the number BG of application entities included in the historical data.

[0104] Step S314, according to the confidentiality correlation function The density BJ is calculated, where , , is the scaling factor and is greater than 0.

[0105] In actual use, the higher the confidentiality of the data, the higher the security of data transmission. If the data is public data, the confidentiality of the data is 0. For example, the temperature and other information of the meteorological station are public, so these data are not confidential. The fewer people who are allowed to access the data, the higher the confidentiality of the data. For example, the number of people who access scientific research data and some corporate core data is only a few internal people. The fewer the number of people who access, the higher the confidentiality level of the accessed data. The transmission of some state secret data requires attention to the security of data transmission, and the confidentiality and security of the data are determined according to the loss of data transmission leakage. For example, the transmission security of state secret data needs to be higher than the security of personal medical record information transmission. At the same time, the more application subjects are included, the more information content the data involves, the higher the confidentiality, and the more secure transmission is needed.

[0106] The steps for obtaining the user's speed requirement value AS for the main data types are as follows:

[0107] Step S321, obtaining the function of the main data type, and determining whether the data transmission speed directly affects the realization of the function.

[0108] Step S322: If the data transmission speed directly affects the function realization, the required data transmission speed is obtained, and the speed requirement value AS is obtained according to a preset positive correlation curve between the required speed and the speed requirement value.

[0109] Step S323: If the data transmission speed does not directly affect the effect realization, the proportional coefficient CB between the transmission speed and the effect is obtained by statistics.

[0110] Step S324, obtain the data validity time CX of the main data type, and associate the function according to the speed requirement Calculate the speed requirement value AS, where , is the scaling factor and is greater than 0.

[0111] In actual use, the transmission speed of some data will directly affect whether the final effect will be achieved. For example, during stock trading, slow data transmission will easily lead to stock trading failure. If the transmission speed directly affects the effect, the faster the required transmission speed, the higher the speed requirement. Some data does not affect the effect, but it will affect the effect of the effect. For example, in fault monitoring, slow data transmission will lead to a later time to discover the fault, affecting the time for timely repair of the fault. The larger the ratio coefficient between transmission speed and effect, the greater the impact of data transmission speed on the effect, the greater the speed requirement, and the shorter the effective time of data, the faster the transmission is needed, otherwise the data received by the user will be invalid, affecting the effect of the data.

[0112] The steps of obtaining the coverage of the repeater, forming a repeater layout diagram according to the initial deployment quantity of all data areas, and obtaining the initial deployment position of the repeater are as follows:

[0113] Step S41, according to the communication quality correlation function The communication quality requirement value DX is calculated, where , , is the scaling factor and is greater than 0.

[0114] Step S42: sort the data areas from high to low according to the communication quality requirement value DX and label them respectively.

[0115] Step S43, the number of repeaters in the first data area is preferentially determined according to the initial deployment number and the best signal position is selected to obtain a first area layout diagram.

[0116] Step S44: Check whether the repeater in the first data area covers the second data area according to the first area layout diagram.

[0117] Step S45: If the repeater in the first data area does not cover the second data area, then according to the initial deployment quantity of the second data area, the best installation position is selected to obtain the second area layout diagram.

[0118] Step S46: If the repeater in the first data area covers the second data area, the coverage area is obtained, and the second deployment quantity of the second data area is adjusted according to the coverage area.

[0119] Step S47, according to the second deployment quantity and antenna isolation requirements, select the best signal position that does not affect the first data area and obtain a second area layout map.

[0120] Step S48, after acquiring all the regional layout diagrams, they are combined to form a repeater layout diagram, and the initial deployment range of each repeater is obtained.

[0121] In actual use, during the deployment of repeaters in different areas, the repeaters are prone to overlapping coverage. At this time, priority is given to areas with higher communication quality requirements. For example, priority is given to the deployment in the military area. After three repeaters are deployed, one of the repeaters covers the scientific research area. When deploying in the scientific research area, if the scientific research area covered by the repeater is large, you can consider reducing the number of repeaters in the scientific research area to save repeater resources. At the same time, according to the location selection of the repeater in the military area, choose a location that does not interfere with the previous repeater for deployment. The deployment of repeaters in all areas takes into account the deployment of the previous area, effectively saving resources and reducing mutual interference between repeaters, and finally obtaining a repeater layout diagram.

[0122] The steps of adjusting the initial deployment position according to the base station signal strength to obtain the advantageous deployment position are specifically as follows:

[0123] Step S51, determining whether the number of data areas covered by the repeater is one, if the number of data areas covered by the repeater is one, extracting the speed requirement value and speed safety value corresponding to the data area.

[0124] Step S52, according to the initial deployment position, the moving range distance is set, and the adjustment range of the repeater is obtained according to the moving range distance and recorded as the initial deployment range.

[0125] Step S53, selecting a location that meets the repeater deployment requirements within the initial range and recording it as a candidate deployment location.

[0126] For some areas with severe electromagnetic interference, inability to meet power supply, and non-compliance with laws and regulations, repeater deployment is not possible, so they need to be removed and locations that meet deployment requirements should be selected.

[0127] Step S54, obtaining the distance EL between the candidate deployment position and the signal source, obtaining the shielding area EM on the transmission path of the candidate deployment position, and calculating the distance EL between the candidate deployment position and the signal source according to the position speed function. The position speed value ES is calculated, where , is the scaling factor and is greater than 0.

[0128] Step S55, obtaining the interference degree of the to-be-selected deployment location, and obtaining the location safety value EA according to the association curve between the preset interference degree and the location safety value.

[0129] Step S56, selecting a candidate deployment position whose position speed value reaches the speed requirement value and whose position safety value reaches the safety requirement value as the advantageous deployment position.

[0130] Step S57: If the number of data areas covered by the repeater is not one, the speed requirement values ​​and speed safety values ​​of all covered data areas are obtained to obtain an advantageous deployment position.

[0131] In actual use, after the initial position is determined according to the number of repeaters, the position of the repeaters needs to be adjusted according to the needs of different data areas to maximize the effect of the repeaters. If the area covered by the repeater has only one data area, only the corresponding data area needs to be considered. When increasing the data transmission speed, the repeater should be deployed close to the base station or signal transmission source to reduce the attenuation of the signal during transmission, thereby increasing the received signal strength and thus increasing the data transmission speed. At the same time, avoid tall buildings, trees and other obstructions on the signal transmission path to reduce the multipath effect and attenuation of the signal and ensure the linearity and efficiency of signal transmission. When considering data transmission security, the deployment of the repeater should be as far away as possible from other potential interference sources such as wireless communication equipment, radar, high-voltage lines, etc., to reduce the impact of electromagnetic interference on data transmission security. According to the data transmission needs of the area, select a suitable location as the advantageous deployment location.

[0132] If the number of data areas covered by the repeater is not one, the steps of obtaining the speed requirement values ​​and speed safety values ​​of all covered data areas and obtaining the advantageous deployment position are as follows:

[0133] Step S571, obtaining speed requirement values ​​and speed safety values ​​of all covered areas, and selecting the highest speed requirement value and speed safety value as reference speed requirement value and reference speed safety value, respectively.

[0134] Step S572, calculate the position safety value and position speed value of the candidate deployment position, and select the candidate deployment position that meets the reference speed requirement value and the reference speed safety value as the advantageous deployment position.

[0135] Step S573: If the candidate deployment position does not reach the reference speed requirement value and the reference speed safety value, the coverage area of ​​the covered data area is obtained, and the data area with the largest coverage area is selected as the main data area.

[0136] Step S574, select a candidate deployment position whose position safety value and position speed value respectively reach the speed requirement value and speed safety value of the main data area as the advantageous deployment position.

[0137] In actual use, if the area covered by the repeater station is more than one data area, it is necessary to consider multiple data areas and select the maximum speed requirement value and the maximum speed safety value as a reference for location selection, so that all data areas covered by the repeater station can be satisfied. If there is no location that can fully satisfy all areas, try to satisfy the main covered data areas.

[0138] The steps of obtaining the environment conditions of the advantageous deployment position, adjusting the advantageous deployment position according to the environment conditions, and obtaining the optimal deployment position are as follows:

[0139] Step S61, obtaining the environmental conditions of the advantageous deployment location, the environmental conditions including the location temperature, location humidity and location wind speed.
