Abstract

The invention discloses a terminal for water level detecting. The terminal comprises a central processor, an RS485 interface, an AD converter, an ultrasonic water level gauge, a FLASH storage and an RCT real-time clock. The RS485 interface, the FLASH storage and the RCT real-time clock are all connected with the central processor. The AD converter is connected with the RS485 interface. The ultrasonic water level gauge is connected with the AD converter. According to the principle, the terminal cannot be polluted by a water body, detecting results are accurate, and remote control can be achieved.

Description

technical field [0001] The invention relates to the field of water level monitoring, in particular to a terminal for water level detection. Background technique [0002] In the water level data acquisition system and hydrological automatic measurement and reporting system, it is usually necessary to measure the water level of rivers, lakes, reservoirs, estuaries, channels, ship locks and various hydraulic structures to realize the monitoring of the hydrological system. However, we hope that this kind of monitoring can realize the collection of sensor data, upload it to the central station through various communication networking modes, and the central station will perform model calculations based on the collected data to provide early warning services. The central station then performs remote recruitment testing, remote configuration, and remote maintenance on the remote control terminal. Rivers, lakes, reservoirs and estuaries are the most common ways for us to get drinkin...
