Abstract

The invention relates to sludge drying monitoring system and method based on a wireless sensor network. The system comprises an oxygen sensor, a temperature sensor, a humidity sensor, wireless sensor network equipment, a power supply unit and computer application software. The method is realized through the sensors and the computer application software. After being started, the system is capable of acquiring oxygen, temperature and humidity signals in a sludge drying device and remotely sending data back to a monitoring center, thereby facilitating the master of parameters in a sludge drying process in real time. The sludge drying monitoring system and method have the advantages that the wireless sensor network facilitates in-situ wiring; and in-situ monitoring is strong in representativeness, thus facilitating the monitoring in the whole process and the comprehensive master of the dynamic change of sludge drying.

Description

technical field [0001] The invention relates to a system and method for monitoring sludge drying based on a wireless sensor network, in particular to a system and a method for monitoring parameters in a sludge drying process using a wireless sensor network. Background technique [0002] Sludge drying refers to the process of removing most of the water content from sludge and is an important step in the sludge management system. The volume of sludge is greatly reduced by drying, and the dried product is stable, odorless and pathogen-free, and can be used as fertilizer, soil conditioner, alternative energy, etc. In the sludge drying process, temperature, humidity and oxygen content are important parameters of the drying process, and comprehensive acquisition of these parameters plays an important role in improving the sludge drying process. Although there are some methods to obtain the parameters in the sludge drying process, due to the method of sampling and analysis, there ...
