The Instrument Of Measuring And Reporting The Ice-Length And Its System

This paper introduces the status of the measuring of the ice' s length in our country and abroad and indicates the shortage, then shows the research object-the instrument of measuring the length of ice and its system. The system uses the different inductive characteristics of water and ice, the integrated encoding and decoding characteristics, and the circuit of string, and realizes a new method of measuring the length of ice.The article mainly narrates the system in two parts. Firstly, it describes the hardware including the sensor, collecting and processing circuit, and the display circuit. Secondly, it presents the system' s software composed of the main program, the second interrupt program, and the communication interrupt program, and discuss the status of RAM.The system can be widely applied to the measuring of the length of ice in the channel, river, reservoir, the lake, and so on. The system can provide the credible data for the water conservancy system, is promising in the prospect of market.
