The invention discloses an OpenAPI conversion
system and method based on a multi-
Modbus bus protocol, and the
system comprises the steps: employing an independent
processing mechanism of each module,and building a connection state with manufacturer equipment through a
serial port communication module, a TCP communication module, and a
data access module under a plurality of
Modbus protocols; achieving conversion between manufacturer data and upper-layer application
system data through the
data conversion module, so that
data conversion does not need to be carried out again when a third-partysystem is in
butt joint; adapting different-end storage
modes of a manufacturer through self-defined
data type codes; using a
Modbus protocol analysis module to monitor the connection state with equipment of a manufacturer in real time, and automatically reestabihsing a connection when a connection fault occurs. According to the invention, through configuration, the Modbus
standard protocol is adapted to perform unified deployment, a plurality of Modbus TCP / IP
bus devices and a plurality of Modbus serial
bus devices can be supported at the same time, and
secondary development is reduced to themaximum extent or even avoided;
data acquisition is reported in a unified manner, and
data consistency is kept; and by effectively filtering the reported data, the
data processing pressure of the upper application system is reduced.
