Data collection method and data collection system for hydrologic monitoring

Abstract

The invention relates to the technical field of hydrologic monitoring equipment, in particular to a data collection method and a data collection system for hydrologic monitoring. The data collection method for hydrologic monitoring comprises the steps that before fish lead is placed in water, communicating connection confirmation and time confirmation are performed on an upper computer and monitoring equipment; after the fish lead is placed in the water, the upper computer performs timekeeping synchronously, the monitoring equipment starts data information collection, and collected data information is saved piece by piece according to a time order; and after the fish lead is taken out of the water, the upper computer stops timekeeping, the monitoring equipment uploads the collected data information to the upper computer, the upper computer sorts out the data information with reference to collection time, and the sort-out data information is saved into the upper computer. The data collection method and the data collection system for hydrologic monitoring are used for realizing barrier-free point-to-point transmission of the data information collected underwater by the monitoring equipment; and the method and the system are accurate, reliable and free of a complicated maintenance workload.

Description

technical field [0001] The invention relates to the technical field of data acquisition, in particular to a data acquisition method and a data acquisition system for hydrological monitoring. Background technique [0002] In the existing hydrological monitoring practice, it has always been difficult to accurately and effectively transmit the data information collected by the monitoring equipment to the host computer on the shore. There are two traditional solutions, one is to use wired connection to transmit , but there are many inconveniences in the wired connection, especially the pulley assembly on the lead fish cableway, which is prone to problems such as poor contact, rusty underwater cables, too far away, too weak signal, and intermittent signal lights; It adopts the method of sound wave and wireless communication for transmission, that is, a communication module for underwater and water conversion is installed on the shore. One end of the module goes deep into the wate...

[0002] In the existing hydrological monitoring practice, it has always been difficult to accurately and effectively transmit the data information collected by the monitoring equipment to the host computer on the shore. There are two traditional solutions, one is to use wired connection to transmit , but there are many inconveniences in the wired connection, especially the pulley assembly on the lead fish cableway, which is prone to problems such as poor contact, rusty underwater cables, too far away, too weak signal, and intermittent signal lights; It adopts the method of sound wave and wireless communication for transmission, that is, a communication module for underwater and water conversion is installed on the shore. One end of the module goes deep into the water to receive underwater sound wave signals, and the other end extends out of the water for air wireless transmission. The data is transmitted to the host computer. This method also has many problems. For example, the communication module used for underwater and underwater conversion will be destroyed when the flood strikes, and when the sediment content is high, there will be great interference in the underwater acoustic communication. , Especially the acoustic wave communication with a long underwater distance is more obviously interfered, and the maintenance of the whole equipment is more difficult
