Embodiment

[0020] see figure 1 , the present invention is based on the Lora spread spectrum wireless long-distance environmental monitoring system, which includes an on-site data acquisition part, an intermediate data server part and an upper-end application display part. The on-site data acquisition part consists of a water level monitoring subsystem, a temperature detection subsystem, and a gas detection subsystem. It is composed of two subsystems, mainly collecting the temperature, water level, and gas information inside the cable trench and shaft, and sending them to the nearest Lora / 4G gateway device after sorting out, and the Lora / 4G gateway device forwards the received information to the remote intermediate data server part, The cloud server of the intermediate data server part includes data storage, data management, data analysis and early warning modules, and the intermediate data server part communicates with the upper-end application display part.

Abstract

The invention relates to an environmental monitoring device for a power communication system, and in particular relates to a monitoring system for ensuring optical cables in a cable trench and a vertical shaft to work safely and reliably. The environmental monitoring system based on Lora spread-spectrum wireless long-distance comprises a field data acquisition part, an intermediate data server part and an upper-end application display part; the field data acquisition part is composed of three sub-systems comprising a water-level monitoring sub-system, a temperature detection sub-system and a gas detection sub-system, mainly acquires temperature, water-level and gas information in the cable trench and the vertical shaft, and sends the temperature, water-level and gas information to the nearest Lora/4G gateway equipment after sorting out the temperature, water-level and gas information; the Lora/4G gateway equipment forwards the received information to the remote intermediate data serverpart; the cloud server of the intermediate data server part comprises data storage, data management and data analysis and early-warning modules; and the intermediate data server part and the upper-end application display part are in communication connection. The problem that the traditional wired communication mode is not reliable any longer when the environment of the cable trench is changed canbe solved.

Description

technical field [0001] The invention relates to an environment monitoring system, in particular to a wireless long-distance environment monitoring system based on Lora spread spectrum. Background technique [0002] Power system communication is an indispensable and important part of the power system, the basis of power grid dispatching automation and production management modernization, and an important technical means to ensure the safe, economical and stable operation of the power grid. As a bridge, the communication optical cable provides a reliable transmission channel for the protection, security control, automation, dispatching telephone, administrative telephone, comprehensive data, conference TV and other services of power production and operation management. Protecting optical cables from damage is of great significance to the safe operation of power grids. [0003] With the increasing investment in national power infrastructure year by year, the length of power tu...
