Description
Technical Field
[0001] This utility model relates to the field of industrial production material supply technology, and in particular to a central material supply system using a bus control system. Background Technology
[0002] In the field of centralized material supply in industrial production, the centralized material supply control system is the core equipment for realizing automated material conveying and distribution, and its stable operation directly affects production efficiency.
[0003] The existing central material supply control system has a significant structural design flaw: the signal from each conveying point needs to be connected to the main PLC control module via an independent cable. This connection method results in the need to lay a large number of cables during system construction, which not only increases material costs and construction complexity, but also significantly increases the probability of cable breaks during construction due to the large number of cables and the long laying distance, thus affecting the system installation quality.
[0004] Furthermore, due to the large number of cables and their complex connections, when a system malfunctions, technicians find it difficult to quickly locate the fault. They need to check a large number of cables and connection nodes one by one, which makes the subsequent troubleshooting work time-consuming and laborious, seriously affecting the speed of production recovery and causing unnecessary losses to the company.
[0005] Therefore, there is an urgent need for a central material supply control system that can reduce cable usage, simplify connection structure, and facilitate fault diagnosis in order to solve the above-mentioned problems of existing technology. Utility Model Content

Each bus module has a unique communication address. Each bus module is connected to a splitter, the splitter is connected to the line server, the line server is connected to the touch screen controller, and the bus modules are connected to each other via power lines and communication lines based on the RS485 protocol.
[0008] Furthermore, the splitter has a signal input terminal and a signal output terminal. The signal input terminal is connected to the signal output interface of the corresponding bus module, and the signal output terminal is connected to the signal input interface of the line server.
[0009] Furthermore, it also includes feeding equipment and material dispensing equipment. The feeding equipment includes a central fan, a separate material suction machine, a dryer, and a storage tank. The material dispensing equipment includes an injection molding machine. The bus module is connected to the central fan, the separate material suction machine, the dryer, the storage tank, and the injection molding machine, respectively.
[0010] Furthermore, it also includes multiple material shut-off valves, which are installed on the conveying pipeline connecting the material supply equipment and the material consumption equipment, and the bus module is connected to the material shut-off valves.
[0011] Furthermore, the power lines are connected to the bus module, the splitter, and the line server, respectively, and the communication lines are connected to the bus module, the splitter, and the line server, respectively.
[0012] Furthermore, the touchscreen controller is equipped with a human-machine interface.
[0013] The beneficial effects of this utility model are as follows: by arranging only power and communication cables between each site and using RS485 communication for signal transmission, the amount of cables used is greatly reduced, thereby reducing the possibility of wire breakage caused by numerous cables during construction and simplifying the troubleshooting process later.

[0016] Reference Figure 1 The present invention proposes a central feeding system using a bus control system, comprising a touch screen controller 1, at least one line server 2, multiple distributors 3, and multiple bus modules 4. The specific technical solution is as follows:
[0017] Bus module 4 is the lowest level of the system structure. Each bus module 4 has a unique communication address, which ensures that each module is unique in signal transmission and avoids confusion. Each bus module 4 is connected to a splitter 3, the splitter 3 is connected to the line server 2, and the line server 2 is connected to the touch screen controller 1, forming a complete link from the bottom-level signal acquisition to the upper-level human-machine interaction.
[0018] Each bus module 4 is connected by two cables: a power cable 5 and a communication cable 6 based on the RS485 protocol. The power cable 5 connects to the bus module 4, the splitter 3, and the line server 2, providing power to each component; the communication cable 6 connects to the bus module 4, the splitter 3, and the line server 2, enabling signal transmission between the components.
[0019] The splitter 3 has a signal input terminal and a signal output terminal. Its signal input terminal is connected to the signal output interface of the corresponding bus module 4, and its signal output terminal is connected to the signal input interface of the line server 2. Through this structure, the splitter 3 can centrally transmit the signals collected by the bus module 4 from each station to the line server 2, realizing the orderly aggregation of signals.
[0020] The system also includes feeding equipment and dispensing equipment. The feeding equipment includes a central fan 7, a separate suction feeder 8, a dryer 9, and a storage tank 10. The dispensing equipment includes an injection molding machine 11. The bus module 4 is connected to the central fan 7, the separate suction feeder 8, the dryer 9, the storage tank 10, and the injection molding machine 11, respectively. It can directly acquire the operating signals of these devices and send control commands to them. In addition, the system also includes multiple shut-off valves 12. The shut-off valves 12 are installed on the conveying pipes 13 connecting the feeding equipment and the dispensing equipment. The bus module 4 is connected to the shut-off valves 12. By controlling the opening and closing state of the shut-off valves 12, the flow of material in the conveying pipes 13 can be adjusted.
[0021] The touch screen controller 1 is equipped with a human-machine interface. Operators can observe the equipment operation status of each bus module 4 corresponding station through the interface. They can also input control commands through the interface. The commands are transmitted to the line server 2 through the touch screen controller 1 and then distributed to the corresponding bus module 4 through the splitter 3, so as to realize remote control of each device.
[0022] With the above structure, this system can realize signal transmission and control of multiple stations with only a small number of cables. Compared with traditional systems, it greatly reduces the amount of cables used, reduces the risk of cable breakage during construction, and because each bus module 4 has a unique communication address, the faulty station can be quickly located in case of failure, which significantly improves the practicality and maintenance efficiency of the system.
[0023] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
