Real-time monitoring system for draining ecological flow under water resources and hydropower engineering and monitoring method thereof

Abstract

The invention discloses a real-timemonitoring system for draining ecological flow under water resources and hydropower engineering and a monitoring method thereof, wherein the monitoring system comprises a power supply source, a flow monitoring device, a data collecting device, a data transmission device and a server; the power supply source is respectively connected to the flow monitoring device, the data collecting device and the data transmission device; an output end of the flow monitoring device is connected to an input end of the data collecting device; an output end of the data collecting device is connected to an input end of the data transmission device; and the output end of the data transmission device is connected to the server. The monitoring method is to acquire the flow datum through a non-contact radar flow monitoring device and then send the information to the data collecting device according to the preset time interval; the datum received by the data collecting device are stored in the data collecting device; and the datum are remotely transmitted to the server in a mobile communication short message service (SMS) way through a GSM / GPRS communication terminal with the preset time interval, thus the time monitoring to the drainage of the ecological flow under the water resources and hydropower engineering is realized.

Description

technical field [0001] The invention belongs to the technical field of water conservancy and hydropower engineering, and in particular relates to a real-time monitoring system and method for ecological flow discharged by a water conservancy and hydropower project. Background technique [0002] With the continuous deepening of our country's understanding of ecological environment protection and the continuous improvement of management requirements, the environmental protection administrative department requires that all water conservancy and hydropower projects must release appropriate ecological flow. In order to strengthen supervision, it is also proposed to build a real-time monitoring system for ecological flow discharge. The requirements of the system require that the system can monitor the ecological flow discharged by water conservancy and hydropower projects in real time and accurately, and transmit the data to the monitoring department in real time.

AI Technical Summary

Problems solved by technology

This method is more suitable for rivers with small flow changes, but the accuracy of measurement data is poor for rivers with large flow changes

[0006] (3) Utilize the operation scheduling data of the project itself: the project operation data used in this method is sometimes not completely leaked ecological flow data, and the data is only controlled by the project scheduling unit, which cannot meet the requirements of remote real-time monitoring

[0007] To sum up, the currently adopted ecological flow monitoring methods and monitoring equipment have their own advantages and disadvantages, but none of them can meet the requirements of real-time monitoring, feedback, and monitoring, and cannot meet the needs of real-time data transmission to the monitoring department.
