Embodiment 1

[0037] figure 1 It is a schematic diagram of a data communication method provided by an embodiment of the present invention, and the method includes the following steps:

[0038] S101: Identify the target type of the pre-installed LoRaWAN communication module.

[0039] A data communication method provided by an embodiment of the present invention is applied to a main control module of a smart watch. The main control module may be a CPU (Central Processing Unit, central processing unit) or an MCU (Microcontroller Unit, micro control unit) in the smart meter.

[0040] When the smart meter is powered on, the main control module identifies the target type of the pre-installed LoRaWAN communication module. The power-on can be the first time the smart meter is powered on, or it can be powered on after the LoRaWAN communication module is replaced.

[0041]When identifying the target type of the pre-installed LoRaWAN communication module, the LoRaWAN communication module can be trig...

Embodiment 2

[0053] Communication in this embodiment of the present invention may include at least one of the following communications: communication during network access, communication during service data transmission, and communication during network status detection.

[0054] On the basis of the foregoing embodiments, invoking the LoRaWAN communication module to communicate with the server according to the set of target command symbols described in the embodiments of the present invention includes:

[0055] Determine the first command character of the network access connection request in the target command character set, and send the first command character to the LoRaWAN communication module, so that the LoRaWAN communication module sends the network access connection request to the server.

[0056] The smart watch can only communicate with the server for business data after the network connection is successful, so before the business data communication with the server, ensure that the...

Embodiment 3

[0079]In order to ensure that business communication can be carried out normally, on the basis of the above-mentioned embodiments, in a data communication method provided by the embodiment of the present invention, the LoRaWAN communication module is called to communicate with the server according to the set of target command symbols include:

[0080] Determine the second command symbol for checking the network status in the target command symbol set, and send the second command symbol to the LoRaWAN communication module, so that the LoRaWAN communication module sends a request for checking the network status to the server.

[0081] If the current network status does not meet the conditions for business communication, it may cause data transmission failure or data loss during business communication, which will affect subsequent operations. It is necessary to check the current network status after the network connection is successful and before conducting business communication...

Abstract

The invention discloses a data communication method and device. The method includes: identifying the target type of a pre-installed LoRaWAN communication module; For each command character set, determine the target command character set corresponding to the LoRaWAN communication module of the target type; according to the target command character set, call the LoRaWAN communication module to communicate with the server. If the LoRaWAN communication module in the smart meter is damaged in the data communication method provided by the present invention, the replaced LoRaWAN communication module can match the existing main control module, thus ensuring the normal communication between the smart meter and the server, Moreover, the main control module does not need to be replaced, and the maintenance of the smart meter is simple and the cost is reduced.

Description

technical field [0001] The invention relates to the technical field of the Internet of Things, in particular to a data communication method and device. Background technique [0002] LPWAN (Low Power Wide Area Network, low-power wide area network), as an Internet of Things access technology that has only been commercialized in recent years, has begun to take shape in some regions in Europe and the United States, and the industrial chain has basically taken shape, while it is still in its infancy in China. It can be said that the development trend that LPWAN will make a big difference in the field of Internet of Things is a foregone conclusion. At present, LPWAN is mainly used in the smart watch industry in China. At present, the large-scale application in the Chinese market is mainly in the long-range (Long Range) technology, and the application of LoRa technology mainly includes LoRa modules, gateways and other devices and thus Form the services provided, etc. The LoRaWAN ...
