Application of Jizhida Intelligent RemoDAQ-83XX Series Products on Ships

With the development of society and the advancement of technology, decentralized data acquisition and communication control modules are also constantly evolving. Beijing Jizhida Intelligent Technology Co., Ltd. has developed RemoDAQ-83XX (Distributed Data Acquisition&Control Module Based on Industrial Ethernet) on the basis of the original RemoDAQ-80XX (Distributed Data Acquisition&Control Module Based on RS-485 Bus). The RemoDAQ-8300 series module is an Ethernet based data acquisition module. They provide analog input, analog output, digital input/output, timer/counter, and other functions. Using Modbus TCP as the communication protocol to facilitate connection with configuration software. Supports 10/100M Ethernet. It can be configured and tested using the RemoDAQ-8300 Series Ethernet IO Module Utility software.

R-80XX is widely used in industries such as transportation, power, railways, ships, petroleum, and coal. Wherever R-80XX can be applied, R-83XX can also be used. Due to the limited communication speed of the serial port to 115200, R-83XX supports 10/100M Ethernet compared to the serial port, which improves transmission speed and stability.

The entire plan includes an upper computer, a lower computer, and acquisition and control equipment, and requires the ability to achieve redundancy. The upper computer uses PPC-150, and configuration software is installed to connect with the lower computer's R-8187 (to achieve redundancy). The acquisition and control equipment uses R-80XX series modules.

The Implementation Scheme of R-80XX and R-8187

R-8017C is responsible for collecting signals from sensors, R-8036 collects the temperature of cylinders, R-8050 is used to monitor the status of various equipment on board, and R-8068 implements control. Once there is an alarm, the honey generator will be activated. R-8187 collects and controls R-8000 series modules through RS485, processes them and places them in fixed registers. The upper computer takes values from R-8187 through Modbus TCP protocol, and the entire redundancy is implemented by R-8187. The upper computer can print and transmit the implementation status to VDR.

Through the analysis of the entire system, the following design scheme can be extended for the R-83XX series products we are currently launching.

Implementation Plan for R-83XX

Due to the fact that the R-83XX series module itself is transmitted via Ethernet and can support multiple computers accessing it simultaneously, implementing redundancy in this architecture is very convenient. With this solution, the R-8187 programmable controller can be eliminated, and the upper computer can be directly programmed to achieve module acquisition and control. This eliminates the need to program R-8187 to control the acquisition device.
