[0030] According to the applicant's research, the Internet of Things meter based on NB-IoT technology generally works in PSM mode when it is designed with low power consumption. In the technology, the data report does not adopt the peak shift method, and does not provide a solution to the problem of continuous invalid reporting and high power consumption. The meter sends data when the network is normal, but does not provide a processing method for data transmission failure, and Start the network access process every time the network is abnormal, and continue the network access operation if the network access fails. This method does not resend the data when the network is normal but the data transmission fails, and the success rate of the data transmission of the IoT table cannot be guaranteed. When the network is abnormal, frequent network access operations increase power consumption, making the power consumption of the meter not low enough. In order to solve the above problem...

Abstract

The invention provides a meter design method, device and system design method based on NB‑IoT Internet of Things, and relates to the technical field of Internet of Things data transmission. The meter design method includes: the meter determines the reporting cycle and the start time of the reporting cycle through a discrete algorithm; the meter starts reporting data to the meter data transmission system when the start time of the reporting cycle arrives, and the meter has reporting failure information When the time comes, the attached network status judgment strategy is automatically enabled to maintain the network, the delay strategy is automatically enabled to extend the reporting cycle, and the retransmission mechanism is used to re-report the reported data; the meter receives and reports failure information based on the meter data transmission system The issued report cycle start time modification instruction modifies the report cycle start time. The method improves the success rate of reporting by retransmitting data, modifying the start time of the reporting period or extending the reporting period according to the specific situation of the report, thereby reducing the power consumption of the meter for data reporting due to retransmission.

Description

technical field [0001] The present invention relates to the technical field of Internet of Things data transmission, in particular, to a meter design method, device and system design method based on NB-IoT Internet of Things. Background technique [0002] The full name of NB-IoT is narrowband Internet of Things (Narrow Band Internet of Things), which is a kind of low power wide area network (LPWAN). Features such as wide coverage, multiple connections, low cost, low power consumption, and excellent architecture. At present, based on NB-IOT Internet of Things smart water and gas meters, according to the technical characteristics of NB-IOT, the PSM mode is used for data reporting. PSM (Power Saving Mode) is a power saving mode. When the terminal enters the PSM state, the transceiver signal will be turned off. It does not listen to paging on the wireless side, does not have any message interaction with the network (network status is maintained), and is in the most power-saving...
