A CDMA-Based Soil-Quality Monitoring System for Mineland Reclamation

International audienceAfter the mining of mineral resource, mineland resources utilization became increasingly complicated. Soil and planting information can be used as the indicators to evaluate mineland reclamation level. In order to obtain the soil and planting information in real time, a CDMA-based soil-quality monitoring system was developed to wirelessly monitor air/soil environment and plant image in remote or local area. As a system test, a monitoring system equipping one network camera and four sensors including air temperature, relative humidity, soil temperature, and soil water content was deployed at a national mineland reclamation demonstration in Fuxin, Liaoning and communicated with a remote server in Beijing using CDMA service with IPsec-based VPN connection. Via a one-year testing, the CDMA-based soil-quality monitoring system as a dynamic infrastructure and available tool showed a good performance for mineland reclamation quality evaluate
