Abstract

The application discloses a self-adaptive fuzzy data uploading method based on NB-IoT. A data uploading time point of equipment is an optimization control object and a reference input is a data uploading time point of the current equipment; error comparison is carried out on a communication result and original data; when an error signal e occurs, an error signal e is selected as an input quantityof a fuzzy controller; fuzzy quantization is carried out on an accurate quantity of an error signal to form a fuzzy quantity; the fuzzy quantity of the error e can be expressed by a corresponding fuzzy language and thus a subset E of the fuzzy language set of the error e is obtained; fuzzy decision making is performed on the E (fuzzy vector) and a fuzzy control rule R (fuzzy relationship) according to a reasoning synthesis rule to obtain a fuzzy control quantity U. In order to apply accurate control to a controlled object, the fuzzy quantity U needs to be subjected to non-fuzzy processing to be converted into an accurate quantity, and after an accurate digital quantity is obtained, a data uploading point of the equipment is modified, so that an optimal uploading time point is finally foundthrough loop optimization.

Description

technical field

[0001] The invention relates to the technical field of data collection, in particular to an NB-IoT-based adaptive fuzzy data upload method. Background technique

[0002] At present, IC card gas meters occupy the main position in smart gas meters. According to incomplete statistics, the national IC card gas meter market has more than 5000×104 units. The IC card gas meter can realize the prepayment function, but the IC card gas meter has its own disadvantages: users need to go to the gas business hall to purchase gas, and users need to queue for a long time to complete the gas purchase during the peak period of gas purchase. For gas companies, there are also problems such as information lag and supply and marketing gaps that are difficult to control. In response to such problems, this paper proposes the design of a wireless remote gas meter based on NB-IoT to solve the problems of information lag and difficult control of supply and marketing gaps.
