[0002] As the construction of automated dry bulk ports accelerates, various sensors, 3D laser scanning imaging, and multi-site cloud monitoring devices of different manufacturers and brands are deployed in the loading and unloading areas of dry bulk terminals. The data collection of these devices is currently processed mainly by modifying the PLC communication protocols of products of different manufacturers and brands, thereby unifying the protocols and facilitating data collection. The secondary modification of the PLC communication protocols of different products increases its complexity, affects the integrity and consistency of the data, and greatly increases the additional development and testing costs of port automation investment and construction, increases the risk of potential communication transmission system failures, and leads to reduced dry bulk loading and unloading efficiency and economic losses.

[0003] In order to solve the data island problem caused by incompatible communication protocols between products and the difficulty of modifying the original PLC communication protocol at the current stage of the port, this patent applies the middleware concept to develop a device that is compatible with multiple PLC communication protocols - an integrated data processor, which breaks the key barrier of data islands and does not require secondary modifications to the original PLC communication protocol. With this patented product, the real-time data of the automated dry bulk loading and unloading site can be fully collected and processed, which improves the decision-making accuracy of the background PC intelligent terminal and reduces the economic investment cost.
