Dam monitoring terminal based on LORA Internet of Things

Abstract

The invention discloses a dam monitoring terminal based on the LORA Internet of Things. The dam monitoring terminal comprises a sensor, a central control module and a LORA communication module. The sensor is used for detecting the water pressure and / or osmotic pressure of a dam. The central control module is used for collecting dam parameters collected by the sensor, controlling the dam monitoringterminal and performing wireless communication with a remote upper computer through the LORA communication module. The LORA, NB-IOT and 3G / 4G / 5G wireless communication are adopted in the invention, the equipment point selection is convenient, the wiring is not needed, the construction and later maintenance cost is effectively reduced, meanwhile, the terminal is compatible with multiple communication modes and can be freely switched in any scene. A centralized control gateway has rich communication interfaces, and various networking modes are supported. The terminal supports an air pressure correction algorithm, so that the data acquisition precision is effectively improved, the Bluetooth APP / PC wireless debugging and setting are supported, the system maintenance is facilitated, the low-power-consumption design is adopted, and the time of sustainable power supply is larger than or equal to 5 years.

Description

technical field [0001] The present invention relates to monitoring equipment, in particular to a dam parameter measurement using LORA Internet of Things technology, which provides one-stop distributed Security monitoring terminal. Background technique [0002] At present, water security and water crisis have become prominent factors restricting my country's social and economic development. The reservoir project is of great significance to the flood control and irrigation of the downstream towns, and has played a huge role in promoting the local economic development, and its status is extremely important. After the dam is completed and impounded, seepage occurs in the dam body, dam foundation and dam abutment due to the effect of the reservoir water level, which is detrimental to the safety of the dam, but it is unavoidable. Effective monitoring of dam seepage will play an important role in dam safety precautions. According to foreign statistics, the accidents caused by da...
