Abstract

The invention discloses a numerical-control phreatic water evaporation automatic water supplementing and monitoring device, which comprises a water level balancer, a Markov bottle, a data acquisition system and a remote monitoring terminal. The bottom portion of the Markov bottle is communicated with the bottom portion of the water level balancer through a communicating pipe; the Markov bottle is internally provided with a water level sensor; the pipeline of the communicating pipe is provided with a water supplementing pump; the water supplementing pump is connected with a water supplementing controller; the water level sensor is connected with an input interface of the water supplementing controller; and the water supplementing controller is also connected with a radio transmitting station. When phreatic water evaporates, the water level balancer and the water level in the Markov bottle decline synchronously; the water level sensor monitors change of the water level; the water supplementing controller controls the water supplementing pump to supplement water to the Markov bottle according to the received water level data to enable the phreatic water level to keep unchanged; meanwhile, the radio transmitting station sends the water level data to the data acquisition system; and finally, collection and monitoring of the phreatic water evaporation data are realized through a remote monitoring server.

Description

technical field [0001] The invention relates to the technical field of hydrological measurement, in particular to a numerically controlled submersible evaporation automatic water replenishment monitoring device. Background technique [0002] Experimental fields such as the study of hydrogeological parameters usually involve observation experiments of phreatic evaporation. At present, a monitoring system composed of a subterranean lysimeter connected with a Malinois bottle is widely used in the measurement of phreatic evaporation experiments. The system realizes the constant pressure automatic control of the water level, and the experimental operation method is relatively simple, but it takes a certain amount of labor costs in the links of water replenishment and data collection, and in the process of manual observation and data collection, there will be data omissions and incorrect readings. Errors, calculation errors and other phenomena affect the reliability of the experim...
