Abstract
The invention discloses a pipeline entrance station non-contact temperature measuring system based on the narrow band internet of things technology. The system comprises a rock wool heat preservationlayer wrapping the exterior of a pipeline wall inside a pipeline entrance station, a protecting layer wrapping the rock wool heat preservation layer, a plurality of pipe wall temperature sensors annularly arranged at the outer wall of the pipeline and arranged inside the rock wool heat preservation layer, an environment temperature sensor fixed outside the protecting layer and provided with a ZigBee transceiving module, and a collector provided with a ZigBee master transceiving module and an NB-loT transceiving module, wherein each pipe wall temperature sensor is fixedly provided with a ZigBeetransceiving module, the ZigBee master transceiving module and the ZigBee transceiving modules on the sensors form a local area network; the ZigBee master transceiving module is connected with an external cloud server through the NB-loT transceiving module. Non-contact type temperature measurement on the pipeline can be achieved.
Description
technical field [0001] The invention belongs to the technical field of narrowband Internet of things, in particular to a non-contact temperature measurement system for pipeline entry and exit stations based on narrowband Internet of things technology. Background technique [0002] Since the distance between the stations in the pipeline transportation is relatively long, and the external environment of the pipeline is very harsh, it is necessary to preheat the medium at each station (ie, the pipeline entry and exit station), and in order to keep the medium in the pipeline at a certain temperature , it is necessary to detect the temperature of the pipeline after preheating. The traditional temperature measurement method is to directly measure the temperature of the medium in the pipeline. This method needs to open holes in the pipeline, which will cause leakage and other accidents, which will affect the strength of the pipeline. Moreover, the cost of this temperature measureme...
