Description

Technical Field

[0001] The utility model belongs to the field of water conservancy equipment, and in particular relates to an MCU device for improving the data collection efficiency of dam safety monitoring based on multi-network switching. Background Art

[0002] With the development of the Internet of Things era, traditional manual inspections are unable to monitor dam safety in a timely manner. The Internet of Things and big data technologies are used to realize online monitoring of dam safety and maintain the safe operation of the dam.

[0003] The reservoir dam safety monitoring system is based on the reservoir dam structure safety monitoring information collection terminal MCU as the core. MCU is the English abbreviation of microcontroller, which integrates the computer's CPU, RAM, ROM, timer counter and various I / O interfaces on a chip to form a chip-level computer. Through wired or wireless transmission, the data collected by the front-end monitoring sensors installed on the reservoir dam are collected into the MCU, and the MCU is uploaded to the remote platform through 4G and the Internet network. Managers can view the operating status of the dam in real time through the platform. At present, there are many dam safety monitoring terminal MCU products in China.

[0004] The collection process of MCU equipment used for dam safety monitoring is generally as follows: the front end uses a sinusoidal sensor to collect the real-time seepage volume, seepage pressure, crack value and other parameters of the reservoir, and the data is transmitted to the terminal MCU device. The MCU terminal EMCU will analyze and store the collected sinusoidal signals, and after edge computing, the valid data will be reported to the dam safety monitoring management platform via 4G or 5G signals.

[0005] The above solution uses 4G or 5G signal single IoT transmission. Reservoirs are generally located in remote areas. Once the signal coverage in the area is poor, it will cause disconnection and data transmission failure. Some MCUs have multiple transmission interfaces, but in actual use, the network port will be occupied, causing disconnection. Utility Model Content
