Abstract

The invention discloses an Internet of things oil fume monitoring system based on an NB-IoT technology. The system comprises several node monitoring boxes, a cloud platform and a network based on theNB-IoT technology. The node monitoring boxes are connected to the cloud platform through the network based on the NB-IoT technology. By using the Internet of things oil fume monitoring system based onthe NB-IoT technology, the cost of an entire oil fume monitoring process can be greatly reduced through the NB-IoT technology. The power consumption of an NB-IoT terminal module is low and a cell isused to provide power, which can not be realized in the prior art. Compared with the mode of using commercial power in the prior art, the mode in the invention can be used to save power consumption cost. In a data transmission portion, the NB-IoT technology is more rapid and stable than GPRS.

Description

technical field [0001] The invention relates to the technical field of oil fume monitoring, in particular to an Internet of Things oil fume monitoring system based on NB-IoT technology. Background technique [0002] The existing oil fume monitoring system uses the oil fume concentration detector to monitor the oil fume concentration information in the oil fume exhaust gas in real time, the working condition sensor collects the operating status of the purifier and the fan, and the oil fume monitoring host uploads the data to the monitoring center through the transmission network, which mainly has the following disadvantages : [0003] 1. GPRS network problem: [0004] a) Packet loss will occur in GPRS, resulting in the loss of transmitted data, and accurate monitoring cannot be realized. [0005] b) The actual rate is lower than the theoretical value. [0006] c) There is a transfer delay, GPRS packets send data in different directions, and finally reach the same destinati...
