Abstract

The invention provides an LoRa temperature and humidity collection system, and the system comprises a server; an LoRa gateway which is connected with the server. A plurality of LoRa temperature and humidity collection modules and the LoRa gateway form a star-shaped network. The LoRa gateway and the LoRa temperature and humidity collection modules query whether the connection between the LoRa gateway and the LoRa temperature and humidity collection modules is normal or not through a link querying mechanism and a heartbeat querying mechanism, and an alarm signal is outputted when the connectionis abnormal. The beneficial effects of the invention are that the start-shaped network structure is formed through the LoRa wireless networking technology; the system is advantageous in long communication distance, low power consumption, strong anti-interference capability and flexible networking; the system can achieve the transparent bidirectional transmission of the temperature and humidity data between multiple devices; the system is suitable for the collection of temperature and humidity data of a machine room, a warehouse, a smart home, the Internet of Things, and an intelligent power grid; the system guarantees the obtaining of the working state of each temperature and humidity collection module in real time via LoRa through adding the link querying mechanism and the heartbeat mechanism, and guarantees the timely discovery of a module with a fault.

Description

technical field [0001] The invention relates to the technical field of temperature and humidity collection devices, in particular to a LoRa temperature and humidity collection system. Background technique [0002] In the prior art, the USR-SENS-WSD temperature and humidity data acquisition module is commonly used when collecting temperature and humidity.
