Extensible data acquisition device of ship power station

Abstract

The invention discloses an extensible data acquisition device of a ship power station. In the device, the outputs of a voltage sampling circuit and a current sampling circuit are respectively connected with an electric energy metering chip, the output of the electric energy metering chip is connected with a singlechip, the output of the singlechip is respectively connected with a 232 communication module, a 485 communication module and a CAN (Controller Area Network) communication module, the electric energy metering chip is connected with a first power supply module, and the singlechip is connected with a second power supply module which is respectively connected with the 232 communication module, the 485 communication module and the CAN communication module. The invention effectively avoids phase deviation, has the function of error report and the advantages of accurate data measurement, greater error tolerance, flexibility, expansibility and stability, high reliability and integrated level, and convenient maintenance, and effectively saves ship space.

Description

technical field [0001] The invention relates to a data acquisition device of a ship power station management system, which is used for collecting electric parameters of generators in the ship power station management system. Background technique [0002] The data acquisition work of the ship power station management system is a crucial link in the management system, which is directly related to whether the management system can correctly and effectively control the generator set. With the expansion of the scale of modern ships, the number of generator sets is also increasing, which requires the data acquisition device to collect the power parameters of all operating units conveniently and reliably. [0003] There are many types of ships in our country, the scale is different, and the number of units on the ship is also different. At present, the data acquisition device is designed according to the number of generator sets in the ship. A single single-chip computer completes ...

Problems solved by technology

[0003] There are many types of ships in our country, the scale is different, and the number of units on the ship is also different. At present, the data acquisition device is designed according to the number of generator sets in the ship. A single single-chip computer completes the power parameter acquisition and control of all generator sets. Therefore, , the data acquisition device is only suitable for a specific ship, and its versatility is not high. Once a failure occurs, the entire system will be paralyzed

On the other hand, the voltage and current signals of the power grid are connected to the device after passing through ordinary current transformers and micro current transformers. More devices are used, the device is large in size, and takes up a larger engine room space. The more units on the ship, the The data acquisition unit will take up more space
