Multi-point water flow temperature synchronous measurement system for warm drainage model

Abstract

The invention provides a multi-point water flow temperature synchronous measurement system for a warm drainage model. The system comprises an acquisition module and a plurality of digital temperature measurement cables connected with the acquisition module, wherein each digital temperature measurement cable is connected with a plurality of temperature measurement cable connectors; the cable connectors are connected with temperature measurement rods with encapsulated digital temperature sensors; the acquisition module acquires temperature signals measured by the digital temperature sensors in the temperature measurement rods through the temperature measurement cable; and the collected temperature signals are transmitted to a computer through an isolated communication convertor for real-time data analysis. The embodiment of the invention measures water temperature by adopting the digital temperature sensors, can greatly reduce use of cables in multi-point water temperature measurement due to the fact that the plurality of digital temperature sensors are connected to one digital temperature measurement cable, has the characteristics of convenient connection, economical application and the like, and can measure and display the temperature of each temperature measurement rod in real time, so that measuring personnel can conveniently perform real-time data analysis on the measured multi-point water temperature.

Description

technical field [0001] The invention relates to water flow temperature measurement, in particular to a computer-controlled multi-point water flow temperature synchronous measurement system for warm drainage models. Background technique [0002] The warm water discharge model test is a special form of the physical model test of water conservancy scientific research. It mainly studies the temperature field of the surface warm water diffusion near the intake and discharge outlets of thermal / nuclear power plants, the vertical temperature rise distribution of the characteristic flow, and the impact of warm water discharge on the ecological environment. influences. It can provide a theoretical basis for thermal / nuclear power plant water environment monitoring, environmental impact assessment, effective management of warm water discharge and ecosystem protection. [0003] Water flow temperature measurement is an important parameter of warm drainage model test and also a parameter ...
