| titleOfInvention | LORA-based single-channel synchronous information acquisition system and method |
| abstract | The invention discloses a single-channel synchronous information acquisition system and method based on LORA, the system is used for synchronously acquiring data of each sensor in an electric power system, and comprises 1 LORA gateway and at least 1 LORA sensor, the LORA gateway and the LORA sensor both adopt single-channel node type LORA chips, and the LORA gateway is used for triggering synchronous acquisition of the LORA sensors and receiving sampling data uploaded by each sensor; the LORA sensor is used for receiving a synchronous acquisition instruction of the LORA gateway, acquiring data and sending sampling data to the gateway; the synchronous acquisition method comprises the following steps: and triggering synchronous sampling of each LORA sensor by using a leading awakening mechanism provided by the LORA, and sequentially uploading data by each sensor according to a set rule. The invention solves the problems that the traditional polling type wireless acquisition scheme based on the LORA technology can not realize synchronous acquisition of sensors and the polling period is long, and simultaneously avoids the problems of high cost and large power consumption of a multichannel gateway type node LORA chip. |
