Embodiment 1
[0020] An adaptive fuzzy data upload method based on NB-IoT, comprising the following steps:
[0021] S1. The uploading terminal sends to the NB-iot base station or server to establish a communication connection, and calculates the connection request time and successful connection time when the pre-transmission data communication connection is made; establishes and stores the data to be transmitted, the connection request time, the successful connection time and the data to be transmitted. The correspondence between the corresponding connection points;
[0022] S2. Perform the difference operation between the connection time and the connection success time to obtain the connection time interval;
[0023] S3. Fuzzy the time interval corresponding to Mx1, Mx2, ....Mxn; specifically:
[0024] The set composed of time intervals is set as the universe of discourse U, and there are m fuzzy subsets on U (that is, m models), constitute a standard model, that is, the fuzzy language ...

[0031] The adaptive fuzzy data upload method based on NB-IoT provides an adaptive fuzzy data upload method. When a large number of smart gas meters have data to upload, the proposed adaptive fuzzy data upload method can calculate the data transmission in real time. The difference between the predicted connection time and the time of successful connection is the key point of data uploading. When batch data needs to be uploaded, the proposed algorithm can effectively realize the intelligent gas data uploading in batches and time. Correct remote transmission. figure 1 The different segment definition intervals are 0≤X<1 hour, 1≤X<2 hours, 2≤X<3 hours, 3≤X<4 hours, 4≤X<5 hours, 5≤X<6 hours, 6≤X<7 hours, 7≤X<8 hours; the corresponding constants are 0.1, 0.2, 0.3, 0.4, 0.5, 0.6, 0.7, 0.8.
[0032] The rectangular line is the step signal waveform, the result of the PID algorithm processing, and the fuzzy algorithm is the output result of the control algorithm proposed in this paper....
