Modular ship valve control system

Abstract

The invention discloses a modular ship valve control system. The modular ship valve control system comprises a valve control module and a communication module, the valve control module comprises a valve main control CPU, a digital quantity feedback acquisition interface and an analog quantity feedback acquisition interface, the digital quantity feedback acquisition interface and the analog quantity feedback acquisition interface are connected with the valve main control CPU, and the communication module comprises a communication main control CPU, and an RS485 communication interface, an 232 communication interface, an Ethernet communication interface and a CAN communication interface which are connected to the communication main control CPU; the valve main control CPU is in communication connection with the communication main control CPU so that information processed by the valve main control CPU can be subjected to communication processing through the communication main control CPU. The system has the advantages that the system is reasonable in structural composition, small in size, low in cost, rapid and stable in operation, capable of greatly improving control precision, good inuse reliability, capable of adapting to severe environments, high in response speed and capable of accurately and conveniently calculating an opening value or outputting an opening signal, modular design is adopted, modules can be used independently or used in a combined mode, different functions can be completed according to conditions, and installation and replacement are convenient.

Description

technical field [0001] The invention relates to a ship valve control device, in particular to an embedded modular valve control device, which belongs to the technical field of ship equipment. Background technique [0002] Traditionally, the ship valve state acquisition and control box is often bulky, using high-cost PLC as the information processing and control system. However, with the continuous development and progress of ship electrical automation technology, the level of ship intelligence continues to improve, and ship equipment continues to Miniaturization, intelligence, and modularization, traditional valve control equipment often cannot meet these new technical requirements. In addition, the existing technical solutions that use PLC as an information processing and control system have relatively low control accuracy, slow response speed, and reliability. The performance is also poor, especially in a harsh environment, and there are often problems that are difficult t...
