Description

Technical Field

[0001] The present invention relates to the technical field of data transmission, and in particular to an interference-resistant data transmission transfer station for ensuring multi-source data in a smart line. Background Art

[0002] Since high-voltage transmission lines extend for tens or even hundreds of kilometers in different environments, they are greatly affected by the geographical environment and climate in which they are located. Every year, power outages in the power grid are mainly caused by line accidents. Traditional transmission line inspections mainly rely on periodic inspections by operation and maintenance personnel. Although they can find hidden dangers in equipment, they lack detection of special environments and climates due to their own limitations. They cannot timely grasp the changes in external forces in the line corridor during the vacuum period of the inspection cycle. It is very easy for line accidents to occur before the next inspection due to lack of monitoring. Therefore, the online monitoring system for ultra-high voltage transmission lines was born.

[0003] When the online monitoring system detects the line data of the power line tower, it needs to transmit the collected data information to the remote server. However, during the transmission process, the transmitted information is incomplete due to the interference inside or outside the transfer station, and the packet loss rate is high. In order to improve the accuracy of data information transmission, it is necessary to enhance the signal strength of the transfer station so that the signal strength of the data information can be enhanced in a targeted manner during the transmission process, thereby improving the accuracy of data information transmission.

[0004] Therefore, how to provide a new type of anti-interference transfer station so that it can specifically enhance the strength of signal transmission and improve the accuracy of data information transmission is a technical problem that needs to be urgently solved by technical personnel in this field.

[0037] The following is a description of the implementation of the present invention by specific embodiments. People familiar with the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0038] In order to solve the related technical problems existing in the prior art, the embodiment of the present application provides an anti-interference data transmission transfer station to ensure multi-source data in the smart line, aiming to solve the problem of data information transmission loss and achieve the effect of improving the accuracy of data transmission. Figure 1 As shown, it specifically includes a receiving module, a processing module, a transfer module and a feedback module. The acquisition terminal at least includes a tower tilt monitoring unit, a dancing monitoring unit, an insulator sag / wind deviation monitoring unit, a video monitoring unit and a communication unit. The tower tilt monitoring unit is used to monitor the tower tilt of the transmission line, the dancing monitoring unit is used to monitor the dancing degree of the transmission line, the insulator sag / wind deviation monitoring unit is used to monitor the sag / wind deviation degree of the transmission line, the video monitoring unit is used to generate a monitoring video of the transmission line, and the communication unit is used to establish communication between the acquisition terminal and the receiving module. The line data information of the transmission line is collected through the acquisition terminal, and the receiving module is used to receive the line data information monitored by each acquisition terminal, and the line data information is transmitted to the processing module after correction by the correction module.

[0039] The correction module receives the line data information at different time nodes collected by the receiving module, corrects the line data information, and transmits the corrected line data information to the processing module.

[0040] The correction formula used by the correction module to correct the line data information is:

[0041]

[0042] Among them, f(i) represents the preset function corresponding to the line data information of different time nodes, f(p) represents the preset function corresponding to the highest line data information, f(q) represents the preset function corresponding to the lowest line data information, and n represents the line data information of n time nodes received.

[0043] For example, when receiving line swing data from the first time to the nth time, the average data of this time period is obtained by eliminating the highest and lowest values ​​and then calculating the average value, thereby realizing data correction.

[0044] The processing module includes a preprocessing unit and a calculation and correction unit. The preprocessing unit preprocesses the line data information received by the correction module, analyzes and encrypts the line data information, and sends it to the transfer module; the calculation and correction unit is used to receive the feedback results of the feedback module and perform signal enhancement processing on the transfer module.

[0045] The transfer module is used to receive the line data information that has been processed by the processing module, and form a first data signal and a second data signal, wherein the first data signal is the original data, and the second data signal is the transmission data obtained after the first data signal is transmitted in the transfer module. The transfer module includes a variety of transmission tools. When the line data information is transmitted in the transmission tool, the transmission tool is subject to internal or external interference, and the transmitted line data information will be interfered and lost. In order to compare and obtain the degree of loss of the transmission data, the feedback module is applied.

[0046] The feedback module is used to receive the first data signal and the second data signal and substitute them into the first comparison method for comparison, determine whether the line data information is interfered with and the interference intensity, and send the comparison result to the calculation correction unit in the processing module, and enhance the signal of the transfer module according to the calculated interference intensity to reduce interference to the line data information.

[0047] like Figure 2 As shown, the first comparison method includes the following steps:

[0048] S1: The feedback module forms a first data curve according to the first data signal through fitting;

[0049] S2: The feedback module forms a second data curve by fitting according to the second data signal;

[0050] S3: If the first data curve and the second data curve are completely consistent, it indicates that the line data information is not disturbed; otherwise, it indicates that the line data information is disturbed;

[0051] S4: based on the interference of the line data information, the fragmentation degree, separation degree and fractal dimension are obtained according to the fitting degree of the first data curve and the second data curve;

[0052] S5: deriving interference intensity of the line data information using a second preset algorithm.

[0053] The second preset algorithm is:

[0054] η=C1*θ1+C2*θ2+C3*θ3

[0055] Among them, η is the interference intensity of the line data information, θ1 is the fragmentation of the line data information, θ2 is the separation of the line data information, θ3 is the sub-dimension of the line data information, C1 is the preset weight of the fragmentation, C2 is the preset weight of the separation, and C3 is the preset weight of the sub-dimension.

[0056] The degree of deviation of the transmitted data from the original data is obtained by comparison, and the interference intensity of the line data information is calculated. The greater the interference intensity, the greater the degree of damage to the line data information, and the greater the degree of signal enhancement of the transfer module is required.

[0057] The calculation correction unit determines whether to perform signal amplification on the transfer module and the amplification intensity according to the comparison result and the first preset algorithm.

[0058] The first preset algorithm is:

[0059] σ=1-(F(η)) η

[0060] Among them, σ is the signal increase strength, η is the interference strength of the line data information, and F(η) is the preset function corresponding to the interference strength η.

[0061] According to the calculated signal increase strength, the signal of the transfer module is enhanced through the gain model, the signal transmission quality of the transfer station is improved, and the error of line data information transmission is reduced.

[0062] The system also includes a remote server, which receives the second data signal after the signal amplification processing in the transfer module. The remote server has functions such as data storage, historical data query, report, printing, and curve drawing, and can perform various analyses on the received line data information, and can perform qualitative and quantitative analysis and trend prediction on the state of the transmission line in operation.

[0063] It also includes a power supply module, which provides power to the receiving module, the processing module, the transfer module and the feedback module.

[0064] The tower tilt monitoring unit used in the acquisition terminal uses the latest MEMS sensor technology and wireless communication technology to conduct real-time monitoring of the two-way tilt angle (along the line direction and perpendicular to the line direction) of power towers located in unfavorable geological areas such as ice disasters, snow disasters, mudslides, landslides, and coal mine goafs. When the tower tilt angle is abnormal, the system can send the warning / alarm information to the monitoring center in time through the GSM / CDMA / GPRS or 4G network to remind the person in charge of line operation to pay attention to the line operation status and take corresponding disposal measures.

[0065] The dancing monitoring unit used in the acquisition terminal uses the latest MEMS sensor technology and wireless communication technology to monitor the conductor dancing frequency and amplitude of high-voltage transmission lines operating in harsh atmospheric environments in real time, and send the monitoring information to the remote monitoring center via GSM / CDMA / GPRS or 4G network.

[0066] The insulator sag / wind deviation monitoring unit used in the data collection terminal uses the latest sensor technology and wireless communication technology to realize real-time monitoring of the sag height and wind deviation angle of high-voltage transmission lines, and sends warning / alarm information to the monitoring center in a timely manner through the GSM / CDMA / GPRS or 4G network, reminding the person in charge of line operation to pay attention to the line operation status and take corresponding disposal measures.

[0067] The video monitoring unit used in the acquisition terminal uses advanced technologies such as digital video compression technology, embedded computer technology and 4G wireless communication technology to conduct all-weather, real-time monitoring of the operating conditions of overhead high-voltage transmission lines operating in harsh environments, allowing managers to understand the dynamic video information of the monitoring point at the first time.

[0068] The acquisition terminal also includes an insulator leakage current monitoring unit, a conductor temperature monitoring unit and a micro-meteorological monitoring unit. The insulator leakage current monitoring unit uses a leakage current acquisition device installed on the top of the insulator string to monitor the leakage current caused by pollution, moisture and other factors of the insulator in real time, and sends the monitoring information to the remote monitoring center through the GSM / CDMA / GPRS / 4G network; the conductor temperature monitoring unit uses a high-precision temperature sensor attached to the conductor to collect the conductor temperature, and sends the collected information to the monitoring center in time through the GSM / CDMA / GPRS or 4G network, thereby realizing real-time monitoring of the conductor temperature; the micro-meteorological monitoring unit can collect environmental temperature, humidity, wind speed, wind direction, and air pressure meteorological parameters in real time, and send the monitoring information to the remote monitoring center through the GSM / CDMA / GPRS or 4G network.

[0069] Although the present invention has been described in detail above by general description and specific embodiments, it is obvious to those skilled in the art that some modifications or improvements can be made to the present invention. Therefore, these modifications or improvements made without departing from the spirit of the present invention all belong to the scope of protection claimed by the present invention.
