Description

Technical Field

[0001] The present invention relates to the monitoring and evaluation of the soil corrosion environment of buried pipelines and grounding grids. Specifically, it relates to an intelligent monitor that is suitable for long-term real-time measurement of the corrosion environment parameters of the soil environment where buried pipelines are located and can remotely transmit data. Technical Background

[0002] Buried pipelines and grounding grids are located in the soil for a long time. China has a vast territory, with various climate environments such as the northwest desert environment, the northeast alpine environment, the southern humid and hot environment, and the seaside salt spray environment. The urban underground space has various harsh corrosion environments such as strong acids, strong alkalis, high humidity, and waterlogging. It can be seen that buried pipelines and grounding grids are involved in various complex soil environments. In order to evaluate the corrosiveness of the soil environment of buried pipelines, it is necessary to measure the main soil corrosion environment parameters that affect pipeline corrosion. These parameters mainly include soil resistivity, temperature, humidity (water content), pH (acidity and alkalinity), redox potential, soil oxygen content, salt content, microorganisms, porosity, etc. Among them, the monitoring technologies for temperature, humidity (water content), and pH (acidity and alkalinity) are relatively mature. Soil resistivity generally uses hand-held detection instruments, and instruments for real-time online monitoring of soil resistivity are rarely seen.

[0003] At present, the automatic acquisition technology of the cathodic protection potential of buried pipelines has been widely applied. However, an intelligent monitor that can simultaneously integrate multiple parameters, conduct real-time online monitoring, and automatically collect and transmit data through the Internet of Things has not been seen yet. There are some automatic acquisition products for temperature, humidity, salt content, pH, conductivity, etc. in the agricultural field on the market, but these products are not suitable for soil monitoring in the buried pipeline environment and do not have online monitoring of soil resistivity. Summary of the Invention

[0004] The present invention has developed an intelligent monitor that integrates multiple parameters (temperature, humidity (water content), pH (acidity and alkalinity), and soil resistivity), conducts real-time online monitoring, and automatically collects and transmits data through the Internet of Things.

[0005] The problems to be solved by the present invention are achieved as follows: The temperature, humidity, and pH are monitored using direct-insert probes, which are suitable for soil environment monitoring; the soil resistivity is monitored using the four-electrode method, which complies with national industry standards.

[0006] The beneficial effects of the present invention are: 1. It has optimized a multi-parameter soil environment intelligent monitor suitable for the soil environment, filling the market and technical gaps in the online monitoring of the soil corrosion environment of buried pipelines; 2. The sensor uses a direct-insert probe, which is convenient for maintenance and replacement. Brief Description of the Drawings

Connect the 9, 10, and 11 probe cables to the monitor respectively. The solar panel 1 is supported and fixed by the bracket 2 and the solar panel column 3. The storage battery 4 is fixed under the solar panel. The antenna 5 is a disc antenna and is glued to the back of the solar panel.
