Meteorological element distributed monitoring system

Abstract

The invention relates to a meteorological element distributed monitoring system. A communication device is arranged between a meteorological element sensor and an upper computer, the communication device receives the detecting signals output by the sensor, the detecting signals comprise an analog signal, a serial signal, a digital pulse signal, etc., the detecting signals then transform into CAN bus data, and the communication device is connected and communicated with the upper computer by using the CAN bus, thereby realizing the arbitrary choices of the distance range, high efficient transmission and the types and quantity of the sensor of the meteorological element information. The meteorological element distributed monitoring system of the invention is less influenced by the scene interference and has strong commonality, which can be used in the distributed modularization and networking monitor of the meteorological element of ship plane and various warehouses in complicated and poor environment, the choices of the quantity and the position of the monitoring spots are flexible, and the invention is characterized by accurate monitoring and reliable operation.

Description

technical field [0001] The invention belongs to the technical field of marine meteorological monitoring, and in particular relates to a monitoring system for signal collection and communication of ship meteorological element sensors. Background technique [0002] As an important part of the measurement system, marine meteorological element sensors have made great progress in the field of marine meteorological observation. At present, such meteorological element measurement sensors mainly include: wind speed, wind direction sensor, temperature, humidity, atmospheric pressure, rainfall, visibility, cloud base height and other meteorological element parameters. At present, the output signals of such sensors mainly have the following forms: serial digital signal RS232 / RS485, parallel BCD code signal, digital pulse signal, analog current signal (4-20mA) and voltage signal (1-5V), etc. This type of signal mainly has the following disadvantages: low signal transmission rate, short...
