[0002] Suspended pole tower assembly is the most common construction method in my country's iron tower assembly projects. The information transmission system that ensures construction safety and efficiency is particularly important. As an important tool to ensure construction safety and efficiency, the reliable monitoring and accurate transmission of information such as safety hazards during the construction process by the information transmission system has become a technical problem that needs to be solved urgently. Considering that the construction process is relatively complex, information transmission is easily affected by mechanical and electrical noise signals, and traditional manual monitoring is difficult to obtain the working status of each part of the tower assembly system in real time and comprehensively. In addition, the existing monitoring system does not fully consider the actual needs of the suspended pole tower assembly project in terms of data communication technology and upper and lower computer design, especially the communication needs, power consumption needs and data transmission requirements between upper and lower computers at the tower assembly construction site. Therefore, it is difficult for the existing information transmission system to ensure accurate information transmission during the construction of the suspended pole tower assembly.

[0090] In order to make the purpose, technical solutions and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not intended to limit the present application. In addition, the technical features involved in each embodiment of the present application described below can be combined with each other as long as they do not conflict with each other.

[0091] The terms "including" or "having" and any variations thereof in the specification, claims or drawings of the present application are intended to cover non-exclusive inclusions. For example, a process, method, system, product or device including a series of steps or units is not limited to the listed steps or units, but may optionally include steps or units not listed, or may optionally include other steps or units inherent to these processes, methods, products or devices.

[0092] As described in the background technology section of the specification, the existing monitoring system has not fully considered the actual needs of the suspended pole holding tower assembly project in terms of data communication technology, upper and lower computer design, etc., especially the communication needs, power consumption requirements and data transmission requirements between the upper and lower computers at the tower assembly construction site. Therefore, it is difficult for the existing information transmission system to ensure accurate information transmission during the construction of the suspended pole holding tower assembly. In view of this, the present application proposes a method and system for processing and transmitting monitoring data for the construction site of a suspended pole holding tower assembly, the purpose of which is to solve the technical problem that information transmission during the construction of the suspended pole holding tower assembly is easily affected by noise signals, and the existing monitoring system is difficult to obtain the working status of each part of the tower assembly in real time and comprehensively, and it is difficult to ensure accurate information transmission, at least to ensure accurate information transmission during the construction of the suspended pole holding tower assembly.

[0093] refer to Figure 1 An embodiment of the present application proposes a method for processing and transmitting data for monitoring the construction site of a suspended pole tower assembly. The method may mainly include the following four steps.

[0094] Step 1: The upper computer receives the monitoring data collected by the lower computer at the construction site of the suspended pole tower assembly based on a preset serial port data transceiver process; the monitoring data includes one or more of tension data, inclination data, and distance data between the pole and the tower body.

[0095] In some embodiments, more specifically, a serial port data transceiver program is designed for data collected by sensors of the lower computer including the tension, inclination, height, distance between the pole and the tower body, etc. at the construction site of the suspended pole tower assembly and then transmitted to the upper computer. Then, the upper computer receives the above data collected at the construction site through the preset serial port data transceiver program. The design ideas of the serial port data transceiver program include the following.

[0096] (1) First, use the serial port wired transmission method to realize data transmission between the upper and lower computers.

[0097] In order to ensure that the data transmission rate is suitable for the data transmission characteristics of the monitoring system and prevent the data transmission rate from being too fast to cause data packet loss or too slow to cause the real-time monitoring to decrease, the serial port configuration is selected: baud rate 115200, data bits 8 bits, stop bit 1 bit, no parity check.

[0098] (2) The serial port data of the host computer is sent and received using the sequence interrupt (i.e., priority interrupt) operation mode.

[0099] When a higher priority task arrives, if the host computer is executing a lower priority task, the serial port will trigger an interrupt and give priority to the higher priority task. The serial port data receiving and sending program is divided into two parts: receiving interrupt mode and sending interrupt mode.

[0100] (3)Reference Figure 2 , when the serial port receives the data from each sensor, it will immediately enter the receiving interrupt mode and wait for the data to be transmitted. In order to determine whether the server has the receiving conditions, it is necessary to determine whether the server has sent a data receiving instruction. After successfully receiving the data, in order to avoid the host computer's misoperation of the interrupt flag, the interrupt flag should be cleared after the data is received. After clearing the interrupt flag, in order to ensure the accuracy of the received data, the IP of the uploaded data must be verified. If the data address matches the acquisition instruction IP issued by the host computer, the reception is executed; otherwise, the waiting reception state is re-entered. After confirming that the received data is correct, the host computer stores it in the buffer for subsequent processing. To prevent data loss caused by buffer overflow, the program should check the storage capacity of the buffer. If the data volume is too large, clear the buffer and then store it.

[0101] (4)Reference Figure 3 When the host computer sends information to each sensor, the serial port enters the sending interrupt mode according to the priority. When the serial port sends an interrupt, it is necessary to determine whether the server has sent a data receiving instruction to determine whether the server has the receiving conditions. After successfully receiving the data, clear the interrupt flag to prevent the host computer from being continuously interrupted. When the server successfully sends the instruction, if the sending buffer is not empty, repeat the data to prevent the buffer from having residual data that has not been sent successfully.

[0102] The present application designs a serial port interrupt receiving and sending program (including receiving interrupt process and sending interrupt process) based on the priority interrupt (sequence interrupt) operation mode, which further realizes the accurate sending and receiving of host computer data.

[0103] Step 2: Based on the compensation angle theory, the distance data between the pole and the tower body received by the host computer is corrected. In some embodiments, more specifically, the specific process of step 2 includes the following.

[0104] (1) First, a coordinate system is established on the tower body. The x-axis of the pole tilt sensor output is set to the horizontal line direction, and the y-axis is set to the line direction. The function expression of the tilt angle is obtained from the monitoring mechanism of the pole tilt sensor:

[0105]

[0106] In the above formula, Sx , S y They represent the monitoring signals of the x-axis and y-axis output by the pole tilt sensor, respectively. m Indicates the output sensitivity coefficient of the pole tilt sensor.

[0107] (2) Further, the inclination angle θ of the pole in the transverse direction and the along-line direction is obtained: x ,θ y The function expressions are:

[0108]

[0109] (3) Based on the geometric relationship of the tower top view interface, the functional expression of the distance L between the pole and the tower body is calculated as:

[0110] L x '=0.5D+htanθ x -lsinθ x

[0111] L y '=0.5D+htanθ y -lsinθ y

[0112] In the above formula, L x ' and L y ' represents the distance from the tower body in two directions of the pole, D represents the width of the tower body at the top, h represents the height difference between the pole top and the tower body, and l represents the total length of the pole.

[0113] The compensation angle theory is used to construct the distance model between the pole and the tower body. The compensation inclination angle is introduced to obtain the corrected function expression of the distance between the pole and the tower body:

[0114] L x =0.5D+htan(θ x +θ0)-lsin(θ x +θ0)

[0115] L y =0.5D+htan(θ y +θ0)-lsin(θ y +θ0)

[0116] In the above formula, L x , L y They respectively represent the distance between the pole and the tower in the horizontal direction and the distance between the pole and the tower in the along-line direction after error correction, θ0 represents the compensation inclination angle. The above functional relationship expressions and parameter values ​​are determined by the compensation angle theory.

[0117] The present application corrects the distance data between the pole and the tower body received by the host computer based on the compensation angle theory, thereby obtaining more accurate monitoring data.

[0118] Step 3: Perform waveform analysis on the corrected distance data between the pole and the tower body, as well as the tension data and inclination data received by the host computer, and perform noise reduction processing through the reorganization filtering algorithm to improve the accuracy of the transmission signal. Figure 4 In some embodiments, more specifically, the specific process of step 3 includes the following.

[0119] (1) First, the data received from the host computer is analyzed for waveform and the corresponding function expression is obtained:

[0120] F(t)=f1(t)+α1(t)

[0121] θ(t)=f2(t)+α2(t)

[0122] L(t)=f3(t)+α3(t)

[0123] In the above formula, F(t), θ(t) and L(t) respectively represent the original tension signal, original inclination signal, and original distance signal between the bracket and the tower body obtained after waveform analysis, f1(t), f2(t) and f3(t) respectively represent the construction site noise signals with Gaussian distribution obtained after waveform analysis, α1(t), α2(t) and α3(t) respectively represent the noisy signals obtained after waveform analysis.

[0124] (2) The discrete noise cardinality, recombined signal cardinality, and signal combination structure are determined by the recombinant filtering algorithm to obtain a more accurate functional expression of tension, inclination angle, and distance between the pole and the tower:

[0125] ∫F(t)φ(t)dt=∫f1(t)(φ(t)+u(t))dt+∫α1(t)(φ(t)+u(t))dt

[0126] ∫θ(t)φ(t)dt=∫f2(t)(φ(t)+u(t))dt+∫α2(t)(φ(t)+u(t))dt

[0127] ∫L(t)φ(t)dt=∫f3(t)(φ(t)+u(t))dt+∫α3(t)(φ(t)+u(t))dt

[0128] In the above formula, φ(t) is the discrete noise cardinality, u(t) is the recombined signal cardinality, ∫F(t)φ(t)dt, ∫θ(t)φ(t)dt and ∫L(t)φ(t)dt represent the tension signal, inclination signal and distance signal between the pole and the tower body after noise reduction processing respectively. The above function expressions and parameter values ​​are determined by the recombined filtering algorithm.

[0129] This application starts from the actual construction situation and determines the discrete noise cardinality, recombined signal cardinality and signal combination structure based on the recombination filtering algorithm, and denoises the monitoring data to make the monitoring accuracy more in line with the actual project and further realize the accurate processing and transmission of data.

[0130] Step 4: Remotely transmit the monitoring data obtained after the noise reduction process. In some embodiments, specifically, for the accurate signal obtained after the recombinant filtering, the 5G DTUWH-G508tf device, Quectel RM500Q device and SIMComSIM8200G device are selected as the remote data transmission basic module of the monitoring system, and a remote data transmission function module including data processing, anti-static and power management is designed to transmit the entire remote data.

[0131] More specifically, refer to Figure 5 and Figure 6 , the remote data transmission basic module includes 5G DTUWH-G508tf device, Quectel RM500Q device and SIMCom SIM8200G device. This basic module can meet the design principle of low power consumption of the monitoring system and realize the remote and stable transmission of tower monitoring data. The 5G DTUWH-G508tf device mainly uses the public network of the operator to provide users with the wireless data transmission required by wireless terminal devices. The DTU (Data Terminal Unit) technology mainly converts the serial port or Ethernet data on site into wireless data, and transmits the data to the remote server through the built-in communication network (such as 4G, 5G and NB-IoT, etc.). When sending data, the Quectel RM500Q device encapsulates and modulates the data of the main device into a 5G wireless signal, and then sends it to the 5G base station through the antenna to realize remote upload of data. The SIMCom SIM8200G device can perform baseband processing of the received 5G wireless signal in the module, including demodulation and decoding, and convert the wireless signal into a digital data format to ensure that the system can recognize the format of the signal.

[0132] The remote data transmission function module includes a data processing module, an anti-static module and a power management module. This function module can meet the design requirements of efficient data processing of the monitoring system and safe and stable operation of the system, and realize the remote and stable transmission of tower monitoring data. As the transmission center of remote data, the WH-G508tf module can meet the functional requirements of data processing and data communication. The WH-G508tf module is powered by a 12V rated voltage to ensure the working performance of the WH-G508tf module. Based on this premise, the outer loop circuit of the data processing module can be designed. The anti-static module design can prevent damage to the circuit caused by human static electricity, and avoid damage to the circuit due to repeated plugging and unplugging of the SIM card in actual engineering.

[0133] refer to Figure 7 , the implementation steps of 5G DTU technology are as follows: First, the data transmission process can be carried out under closed network conditions. Except for the operators holding the equipment on site, no one else can use the data transmission function of the pole tower construction through the network. Then, according to the HTTP and other protocol formats, the transparent transmission mode is selected as the transmission mode. The transparent transmission mode data is sent through the network layer without data processing. After the receiving end receives the data, it is used directly without parsing. The transparent transmission mode supports two-way communication. Not only can the data of the on-site equipment be sent to the server, but the server can also send instructions or data back to the on-site equipment through the transparent transmission mode.

[0134] This application takes into account factors such as data transmission packet loss, data processing rate and network coverage, and designs a remote data transmission module based on 5G communication technology, thereby reducing the packet loss rate of communication data, enhancing the communication data transmission capabilities of the pole tower assembly construction site, and realizing remote and accurate transmission of tower assembly site data.

[0135] Another embodiment of the present application provides a suspended pole tower assembly construction site monitoring data processing and transmission system, and the data processing and transmission system may mainly include the following four parts.

[0136] The data collection and reception module is used to enable the upper computer to receive the monitoring data collected by the lower computer at the construction site of the suspended pole tower assembly based on the preset serial port data transmission and reception process; the monitoring data includes one or more of tension data, inclination data, and distance data between the pole and the tower body.

[0137] The pole-tower distance data correction module is used to correct the pole-tower distance data received by the host computer based on the compensation angle theory.

[0138] The reorganization filtering algorithm noise reduction module is used to perform waveform analysis on the corrected distance data between the pole and the tower body and the tension data and inclination data received by the host computer, and perform noise reduction processing through the reorganization filtering algorithm.

[0139] The remote transmission module is used to remotely transmit the monitoring data obtained after noise reduction processing.

[0140] This application performs serial data transmission and reception interruption operations based on a preset serial data transmission and reception process, achieving accurate transmission and reception of host computer data. Based on the actual construction situation, the noise reduction processing is performed through the reorganization filtering algorithm, so that the monitoring accuracy is more in line with the actual project, and the influence of noise signals on the construction site is overcome, and the accurate processing and transmission of construction monitoring data is achieved, providing a safer guarantee for the tower assembly construction process.

[0141] For the design principles of the serial port data receiving and sending process, the design principles of the pole and tower distance data correction module, the design principles of the reorganization filter algorithm noise reduction module, and the specific technical details of the composition structure of the remote transmission module and the corresponding technical effects, please refer to the aforementioned implementation example of the suspended pole tower assembly construction site monitoring data processing and transmission method, which will not be repeated here.

[0142] This application was tested in a pumped storage power station transmission project in a certain place. Taking the 24# iron tower used in actual engineering as an example, the tower type is 5B 1-ZBC1K, and the total length of the boom is 28m. When the 6th to 8th sections are lifted, the tension of the guy wire, the tension of the lifting rope, the inclination angle of the boom, the height of the hanging piece, and the distance between the boom and the tower body are compared with the theoretical values ​​and the monitored values. The lifting method adopts the single lifting method. Among them, the distance between the boom and the tower body is determined according to the supporting rope binding position and the inclination angle of the boom in the construction plan. In order to verify the accuracy of the system, all parameters are strictly carried out according to the construction plan during the construction process. The comparison of the actual measurement value and the system monitoring value at a certain moment is shown in Table 1.

[0143] Table 1 Comparison of system measurement data and calculation data

[0144]

[0145] As can be seen from Table 1, the average error between the actual field measurement value and the system monitoring value of each parameter is small, all between 4% and 5%, and the smaller the error, the more accurate the data transmission. The method and system for accurate transmission of wireless intelligent monitoring information for suspended pole tower construction are well applied in engineering practice, and the error value meets the engineering requirements. It can be concluded that the proposed method and system for accurate transmission of wireless intelligent monitoring information for suspended pole tower construction is reasonably designed and has high transmission accuracy.

[0146] In summary, the purpose of this application is to solve the technical problem of how to achieve all-round, accurate and real-time transmission of monitoring information at the construction site of a suspended pole-holding tower assembly, so as to improve the safety and efficiency during the construction process. During the construction process, information transmission is easily affected by noise signals, and it is difficult for the existing monitoring system to obtain the working status of each part of the tower assembly in real time and comprehensively, and it is difficult to ensure reliable monitoring and accurate transmission. In response to the above technical problems, this application provides a precise transmission method and system to perform data reception and transmission processing and data transmission at the construction site, overcome the influence of noise signals at the construction site, achieve all-round, accurate and real-time transmission of monitoring information at the construction site of a suspended pole-holding tower assembly, and improve the safety and efficiency during the construction process.
