Description

Technical Field

[0001] The present invention relates to the technical field of port terminal concrete structure and steel structure monitoring, and in particular to a multi-parameter synchronous automatic monitoring system and method for a port terminal. Background Art

[0002] Temperature control during concrete pouring is crucial to the quality of concrete pouring, especially for large-volume concrete pouring. During concrete pouring, if the internal temperature is not well controlled, temperature cracks will appear, affecting the quality of concrete. In severe cases, the concrete structure will be scrapped and need to be dismantled and rebuilt. At the same time, ambient temperature is also a key indicator that affects the test of mechanical properties such as stress and strain. Temperature compensation needs to be made according to temperature data during testing to reduce test errors. For steel structures serving in marine environments, chloride ion erosion can cause rapid corrosion and damage to steel structures, which can lead to catastrophic accidents in severe cases. Therefore, in order to prevent the corrosion of steel structures in marine environments, steel structures in the fields of docks, offshore platforms, and cross-sea bridges often use electrochemical principles to prevent metal corrosion to prevent or slow down the corrosion of steel structures, such as welding and installing anode blocks on steel structures to prevent or slow down the corrosion of steel structures by consuming anode blocks, which is called sacrificial anode cathodic protection. For dock structures serving on silty coasts, mud siltation can lead to safety issues such as ship stranding and increased load on dock structures causing structural damage. Therefore, it is also crucial to monitor the depth of dock siltation. In order to ensure the berthing needs of ships and the safety of the wharf structure, it is necessary to detect the siltation status at the front of the wharf or the slope.

[0003] The most common and direct method for evaluating the cathodic protection effect of sacrificial anodes is to obtain the cathodic protection potential through on-site manual detection, and evaluate the cathodic protection effect level according to the magnitude of the potential; the current method for detecting the depth of silt accumulation at the dock is for staff to take a small boat with a probe to the corresponding point of the dock for testing, record the water depth, and then compare it with the design value to determine the state of the silt.

[0004] However, the manual detection method mainly relies on the detection personnel and divers to collect the protection potential data on site using a multimeter and a reference electrode. This method is time-consuming and laborious, and is greatly affected by environmental factors such as wind and waves, and has certain risks. At the same time, more than 90% of the steel structures serving in the marine environment are generally covered by marine plankton, and it is difficult to obtain the protection potential on site. At the same time, the on-site detection method cannot obtain the protection potential data in real time, the timeliness is poor, and the protection potential level cannot be evaluated in real time, and timely warning cannot be given. Therefore, the corrosion state of the steel piles cannot be well grasped and treatment measures cannot be taken in time. The working efficiency and automation level of this manual detection method are too low, and it is too inconvenient to implement in bad weather, which is not conducive to the monitoring and cleaning of the silt state, and it is impossible to achieve advance forecast and status warning. Therefore, it is urgent to design a multi-parameter synchronous automatic monitoring system and method for port terminals to solve the above problems. Summary of the invention
