The invention discloses a remote monitoring system based on an LoRa technique for a base station machine room, and belongs to the technical field of remote monitoring. The system includes LoRa collecting equipment, an LoRa collector node, a cloud-side server and a monitoring terminal; the LoRa collecting equipment collects environmental data of the machine room, and sends the data to the LoRa collector node; the LoRa collector node transmits a data package to the cloud-side server for storage through a wireless communication network module, and the monitoring terminal remotely accesses the cloud-side server through the internet to check real-time data, send polling tasks to polling staff on the basis of a caution hint and receive polling feedback lists uploaded by the polling staff. According to the remote monitoring system based on the LoRa technique for the base station machine room, the environmental data, such as power distribution, temperature, humidity, the amount of suspended dust particles, smoke granularity, light intensity, of the base station machine room can be remotely monitored, the polling tasks are published to the polling staff through the terminal, maintenance andrepair can be conducted in time, and the communication quality is ensured.
