They are prone to electrochemical corrosion in corrosive environments such as soil and groundwater, which can lead to safety accidents such as leaks and ruptures. Therefore, it is necessary to accurately monitor their cathodic protection potential and corrosion rate to ensure operational safety. The traditional decentralized monitoring schemes currently used in the industry have obvious defects. First, the existing devices collect data in a scattered manner. The cathodic protection potential relies on manual on-site measurement, and the corrosion rate requires periodic sampling or single-point detection, which is inefficient, results in discontinuous data, and lacks unified integration and verification, leading to insufficient accuracy. At the same time, the existing devices are inconvenient to maintain and power supply. The equipment is mostly deployed in remote areas and requires regular on-site maintenance. The mains power supply is limited, and ordinary batteries have short battery life, which can easily lead to monitoring interruptions.

This enables integrated monitoring of cathodic protection data and corrosion rate. Furthermore, the continuous power supply from the solar panel and battery, along with the real-time transmission from the communication module and the data acquisition instrument, facilitates the provision of stable energy to the equipment and the transmission of analyzed data to the monitoring center.

[0016] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.
[0017] Example 1: See Figures 1 to 3 This invention discloses an integrated remote monitoring device for cathodic protection data and corrosion rate, comprising a pile body 1, a pile plate 2 fixed to the pile body 1 and buried underground, a first window 3 opened in the middle of the pile body 1, and a wiring plate 4 installed in the first window 3. A wiring port is provided at the bottom of the pile body 1, through which multiple detection lines are connected. A second window 5 is provided on the pile body 1, allowing for quick opening of a portion of the pile body 1 during subsequent maintenance of the data acquisition instrument 7. The hinged window plate at the second window 5 provides good sealing when closed, preventing rainwater from entering the pile body 1. The second window 5 is located directly above the first window 3, and a detection mechanism for analyzing the data transmitted from the detection lines is installed inside the second window 5. This detection mechanism facilitates the analysis of the data transmitted from the detection lines, enabling the analysis of cathodic protection data and corrosion rate, and transmitting the information to the backend via a communication module. An auxiliary box 6 is installed on the top of the pile body 1, protecting the internal auxiliary mechanism and reducing the impact of collisions. Damage to the structure; the auxiliary box 6 is equipped with an auxiliary mechanism for detecting the periphery of the pile body 1. The detection mechanism includes a data acquisition instrument 7 (AK-CJ-1) installed in the second window 5. The data acquisition instrument 7 can collect, preprocess, store and upload monitoring data of various sensors or monitoring modules of the detection pile in conjunction with the communication module. At the same time, it can receive remote commands to realize remote control and status monitoring of the equipment. The upper end of the data acquisition instrument 7 is connected to a battery 9 through a sealed insulating joint. The battery 9 supplies power to the electronic components inside the pile body 1 and stores the electrical energy absorbed and converted by the solar panel 10. The lower end of the data acquisition instrument 7 is connected to a lightning protection plate 8 through a sealed insulating joint. The lightning protection plate 8 conducts the overvoltage and overcurrent generated by lightning strikes to the ground in the manner of discharge, current diversion and voltage limiting, thereby protecting the electrical components, communication modules and sensors inside the detection pile from damage by lightning strikes. The periphery of the lightning protection plate 8 is abutted against the inner wall of the pile body 1 through a conductive plate, and the lightning protection plate 8 is connected to a ground wire for guiding excess current to the ground.
[0018] In this invention, the auxiliary mechanism includes a solar panel 10 installed at the rear end of the auxiliary box 6. The solar panel 10 facilitates the conversion of solar energy into electrical energy, providing continuous DC power to equipment such as the pile body 1, data acquisition instrument 7, and lightning protection plate 8. The solar panel 10 is connected to the battery 9. A Beidou positioning module 11 is installed on one side of the inner wall of the auxiliary box 6. An electronic level detector 12 (HW-008 electronic digital display tilt meter) is installed at the bottom of the auxiliary box 6 to detect the balance of the pile body 1. The electronic level detector 12 facilitates the inspection of whether the pile body 1 is tilting, preventing the pile body 1 from collapsing due to tilting, which would lead to increased maintenance costs and interruption of data detection. Furthermore, the auxiliary box 6 is equipped with a temperature sensor, a humidity sensor, and a communication module. The temperature and humidity sensors can monitor the area near the pile body 1 in real time. The detection line... The system includes a detection contact 17 connected to the pipeline, a long-term reference electrode 15 buried underground, and a polarization probe 16. The detection contact 17 facilitates the detection of pipeline corrosion rate. The long-term reference electrode 15 provides a stable potential reference, which, together with the polarization probe 16 and corrosion sensor, accurately measures the corrosion potential and cathodic protection potential of the monitored metal body, and determines the corrosion status and protection effect of the metal components. A cylindrical sealing block 14 is installed between the wiring port and the first window 3. The sealing block 14 prevents underground moisture and soil from entering the pile body 1. The detection line passes through the sealing block 14, and a desiccant chamber 13 is placed at the lower end of the wiring plate 4. The desiccant in the desiccant chamber 13 absorbs the moisture inside the pile body 1, ensuring that the inside of the pile body 1 is dry and preventing water vapor from being generated inside the pile body 1 due to temperature from damaging the wiring plate 4.
[0019] Working principle: When using this invention, the device is first firmly buried in the ground near the pipeline to be monitored through the pile plate 2. The detection lines led out from the wiring port at the bottom of the pile body 1 are respectively connected to the detection contact 17 on the surface of the pipeline, the long-term reference electrode 15 buried in the soil, and the polarization probe 16, to ensure that each detection element forms an effective electrical connection with the pipeline and the soil environment being monitored. The detection lines pass through the cylindrical sealing block 14 into the interior of the pile body 1 and are neatly wired on the wiring plate 4 in the first window 3. The desiccant chamber 13 at the lower end of the wiring plate 4 can continuously absorb the moisture inside the pile body 1, keep the internal environment dry, and avoid corrosion of the wiring terminals. When the device is started, the long-term reference electrode 15 buried underground provides a stable potential reference. The polarization probe 16 and the detection contact 17 work together to collect key data such as the cathodic protection potential and corrosion rate of the pipeline in real time. The original electrical signal is transmitted to the detection mechanism in the second window 5 through the detection line. The data first passes through the lightning protection plate 8. The lightning protection plate 8 is in close contact with the inner wall of the pile body 1 through the conductive plate on the periphery. With the help of the ground wire, any possible lightning overcurrent or stray current is safely guided to the ground, effectively protecting the subsequent electronic components from damage. The signal after lightning protection enters the data acquisition instrument 7. The data acquisition instrument 7 performs preprocessing such as amplification, filtering, and A / D conversion on the received analog signal. After converting it into a digital signal, it is analyzed and calculated to obtain the cathodic protection effect parameters and real-time corrosion rate data of the pipeline. Meanwhile, the solar panel 10 at the rear of the auxiliary box 6 converts solar energy into electrical energy under sunlight and stores it in the battery 9, providing a continuous and stable power supply for the data acquisition instrument 7, the Beidou positioning module 11, the electronic level detector 12, and various sensors. The temperature and humidity sensors inside the auxiliary box 6 monitor the temperature and humidity changes of the environment around the pile 1 in real time, while the electronic level detector 12 constantly detects the tilt angle of the pile 1 to ensure that the device itself is in a stable working posture. When abnormal temperature and humidity are detected or the tilt of the pile 1 exceeds the set threshold, the data acquisition instrument 7 will package these abnormal status information together with the cathodic protection and corrosion rate data through the communication module, and combine them with the accurate geographical location information obtained by the Beidou positioning module 11 to remotely transmit them to the monitoring center backend system. After receiving the data, the monitoring center can intuitively display the pipeline corrosion status, cathodic protection system operating parameters, device geographical location and surrounding environmental parameters at each monitoring point on the terminal device, realizing all-weather, remote and real-time monitoring of pipeline corrosion risks. Staff can conveniently perform daily inspections and maintenance on the junction box 4 and data acquisition instrument 7 through the first window 3 and the second window 5 to ensure the long-term stable operation of the device and provide reliable data support for the safe operation of the pipeline.
[0020] Example 2: See Figure 4 and Figure 5 A transfer channel 18 is provided on the outer side of the inner wall of the desiccant chamber 13. A storage chamber 21 is provided on the upper end of the transfer channel 18 on the inner wall of the desiccant chamber 13, and a discharge chamber 20 is provided on the lower end of the transfer channel 18 on the inner wall of the desiccant chamber 13. Transfer guide wheels 19 are rotatably connected to the transfer channel 18, the discharge chamber 20, and the storage chamber 21. The transfer guide wheels 19 are driven to rotate by a drive motor provided in the inner wall of the desiccant chamber 13. The distance between adjacent transfer guide wheels 19 is smaller than the diameter of the desiccant, so that the transfer guide wheels 19 can drive the desiccant to move its position inside the transfer channel 18 during rotation. The testing facility is equipped with moisture-proof and corrosion-proof modules. The dehumidification module calculates the desiccant's moisture absorption capacity and saturation state in real time based on parameters such as the desiccant's adsorption characteristics and ambient temperature and humidity. Once the desiccant is detected to be close to saturation, the rotation mechanism is automatically triggered. The corrosion prevention module cleans and standardizes historical corrosion data, uses an exponential smoothing algorithm to predict short-term corrosion rates, and corrects for these rates by incorporating environmental factors such as cathodic protection effectiveness, soil temperature, humidity, and pH. Based on the prediction results, it further calculates the corrosion loss of the pipeline wall thickness over future periods and establishes a tiered early warning mechanism.

After receiving the replacement command, the rotation module drives the motor to rotate the transfer guide wheel 19. During the rotation of the transfer guide wheel 19, the transfer guide wheel 19 at the storage bin 21 position moves the desiccant inside the transfer channel 18 to the storage bin 21 position, and the transfer guide wheel 19 at the discharge bin 20 position moves the desiccant inside the discharge bin 20 to the transfer channel 18 position. The transfer guide wheel 19 stops after rotating a set number of times.

This is the maximum corrosion rate allowed by the industry. when When a long-term early warning is triggered, an "orange warning notification" is sent to the operation and maintenance department and pipeline management personnel, along with a "remaining wall thickness prediction report" (including the current wall thickness, the estimated time to reach the safety lower limit, and the corrosion development trend), so that pipeline operation and maintenance personnel can take targeted measures. This represents the initial wall thickness of the pipe. This is the lower limit of the safe wall thickness; Preprocessing: The collected data is sorted according to the collection time, and corresponding items collected at the same time are processed. averaging the data and standard deviation The calculation, and the mean obtained from the calculation. and standard deviation Collect data fluctuation range for corresponding items The system is configured to compare the collected data for a given item with its fluctuation range, mark data outside the fluctuation range as outliers, and record the number of outliers. ,like If the collected data is abnormal, the data will be re-tested; if If outliers are removed, the mean of the remaining corresponding test data after outlier removal is calculated.
