Embodiment Construction

[0018] The temperature and humidity monitoring system of the present invention includes several temperature and humidity sensors TS, several industrial hubs HUB, programmable controller PLC and man-machine interface HMI.

[0019] A temperature and humidity sensor TS is installed in each cabin of the ship to be monitored, and 3 to 5 similar cabins are divided into one area, each area is equipped with an RS485 bus, and each temperature and humidity sensor TS in each area will collect the temperature and humidity The information is transmitted to the industrial hub HUB through the RS485 bus in this area.

[0020] Each industrial hub HUB is connected to no more than four RS485 buses. The industrial hub HUB integrates at least four digital signals into one digital signal and transmits it to the programmable controller PLC.

[0021] The programmable controller PLC further includes several communication modules and a central processing unit CPU, and the number of communication module...

Abstract

The invention discloses a marine temperature and humidity monitoring system. The system comprises a plurality of temperature and humidity sensors, a plurality of industrial concentrators, a programmable controller and a human-computer interface, the industrial concentrators integrate a plurality of digital signals into one digital signal and sends the digital signal to a communication module in the programmable controller, interference caused by the fact that multiple signals are directly connected to the communication module is avoided, and the programmable controller and the human-computer interface are connected in a wired mode and have a self-adaptive function. The temperature and humidity monitoring system provided by the invention has the advantages of vibration resistance, wide monitoring range, simple communication, convenient wiring and the like, and can work normally under extreme conditions of marine navigation.

Description

technical field [0001] The invention belongs to the technical field of temperature and humidity monitoring, in particular to a marine temperature and humidity monitoring system. Background technique [0002] With the development of ship automation and large-scale, the requirements for reliable operation of electronic and intelligent equipment used in ships are getting higher and higher. Ambient temperature and humidity are important factors affecting the reliable operation of electronic and intelligent equipment. When sailing at sea, the humidity is high and the temperature changes greatly. The environmental monitoring of each important cabin on the ship can only be determined through regular inspections, and real-time monitoring cannot be carried out. [0003] In order to discover the impact of temperature and humidity on the normal operation of equipment in time, it is necessary to monitor the room temperature and humidity of each cabin in real time. The temperature and h...
