Abstract

The invention belongs to the flow monitoring technical field and in particular relates to a stream flow monitoring device and a stream flow computing method. The stream flow monitoring device comprises a flow velocity measurement module, a water level measurement module, a microprocessor module, a storage module, a keyboard display module, a GPRS (General Packet Radio Service) module and a power supply module, wherein the flow velocity measurement module adopts an ultrasonic transducer and adopts an ultrasonic velocity difference method to calculate the stream flow velocity; the water level measurement module adopts the ultrasonic transducer to calculate the water level and then calculates the cross section area of a stream channel, so as to calculate the stream flow; and the GPRS module can realize remote data transmission and further realize real-time control. According to the stream flow monitoring device, the stream flow can be monitored in real time and remote data transmission can be realized, the stream flow monitoring device has the advantages that no contact measurement is adopted, installation is simple, little influence on equipment is caused, the accuracy is high and remote transmission can be realized, and is very suitable for monitoring the stream flow of small hydropower stations in mountainous areas of China.

Description

technical field [0001] The invention belongs to the technical field of flow monitoring, in particular to a river flow monitoring device and a river flow calculation method. Background technique [0002] Small hydropower is widely distributed in mountainous areas far away from large power grids due to its small scale, simple engineering, short construction period, quick returns, full use of natural resources, and good ecological benefits. It is an important part of rural energy in my country. In the process of small hydropower generation, river flow is an important factor affecting the benefits of small hydropower generation. Accurate and real-time monitoring of river flow can take timely measures in wet / dry seasons to ensure the effective power supply of small hydropower, and it is also the key to rationalize rural electricity consumption. link. Therefore, real-time monitoring of river flow in the process of small hydropower generation is of great significance to control th...
