Description

A control system for thin tobacco shred production line

technical field

The technical solution to be protected by the utility model relates to a control system for a thin tobacco shred production line. the

Background technique

The shredded tobacco production line is a production process from flakes to shredded tobacco. The production processes include storage, humidification, shredding, sorting, dehumidification and boxing. the

Because the equipment layout of the production line is relatively scattered and the control is complicated, the traditional control mode is that the control unit and the execution unit are installed in one or several control cabinets, and then the motor, field control unit and equipment are connected to the control cabinet through cables. Inside the cabinet. Although the components of this control mode are concentrated first, there are disadvantages such as a huge amount of connecting wires, a long installation period, many fault points, difficult maintenance, and inconvenient expansion in the later stage. the

In terms of network, due to the poor compatibility of the field bus ProfiBus and its short transmission distance, the number of stations that can be accommodated and the transmission speed are limited. If the management and field control are placed in the same network, it will be very difficult to implement. Slow, unable to achieve long-distance data sharing, and will affect the security of on-site control data. the

Utility model content

The technical problem to be solved by the utility model is to provide a tobacco thin shred production line control system to achieve remote operation and monitoring of the production line, remote sharing of real-time data and creation of a database for production process data in view of the deficiencies of the prior art the goal of. the

In order to solve the above-mentioned technical problems, the technical solution of the utility model is a control system for a tobacco thin shred production line, which is characterized in that the control system includes a PLC main controller, a router, a monitoring operation station, and a substation. The main controller is connected with at least two monitoring operation stations through the communication module, ProfiNET bus and router, and the PLC main controller is connected with the sub-stations controlled by the monitoring operation station through the CPU communication port and the ProfiBus bus. the

The monitoring operation station is a monitoring computer or server, and communicates with the router through the Siemens industrial communication card CP1613A2. the

Described sub-station is provided with communication module, and the model of communication module is Siemens S7 ET200S. the

A control system for a thin tobacco shred production line. Due to the adoption of the above structure, the system adopts a control mode combining a communication module and a ProfiBus field bus. The on-site equipment is divided into different functional blocks according to their functions. Each functional block has a substation. All the control and execution units in this block are in the substation. Each substation is hung on the ProfiBus bus and connected through the network. Go to the communication module of the PLC main controller to communicate with the PLC main controller. The control system has simple structure, convenient maintenance, less wire consumption and greatly reduced installation period of the control system. the

Description of drawings

Below in conjunction with accompanying drawing and specific embodiment the utility model is described in further detail;

Fig. 1 is the structural block diagram of the control system of the utility model tobacco thin shred production line;

In Fig. 1, 1. PLC master controller; 2. router; 3. monitoring operation station; 4. substation. the

Detailed ways

As shown in Figure 1, a kind of control system of tobacco thin shred production line, described control system comprises PLC main controller 1, router 2, monitoring operation station 3, substation 4, PLC main controller 1 passes communication module 5, ProfiNET The bus and router 2 are connected to two monitoring and operating stations 3, and the PLC main controller 1 is connected to the substation 4 controlled by the monitoring and operating station 3 through the CPU communication port and the ProfiBus bus. the

For the on-site control part, the system adopts the control mode combining the communication module and the ProfiBus field bus. The on-site equipment is divided into different functional blocks according to their functions. Each functional block is equipped with a substation 4. All control and execution units in this block are in the substation 4, and each substation 4 is hung on the ProfiBus bus. , connected to the communication module 5 of PLC main controller 1 through the network, and communicate with PLC, the communication module 5 adopts Siemens S7 series CPU 414-2DP with communication port, and the communication module of each substation 4 adopts S7 ET200S. the

For the management part, the system’s operation of the production line, the processing of working parameters, control parameters and database data are all completed through the management network ProfiNET. The ProfiNET network has the advantages of fast speed, simple interface, long transmission distance and compatibility with InterNet, etc. Advantages, therefore, the remote operation and monitoring of the production line and the remote sharing of real-time data can be realized, and, with the support of the industrial control software WinCC, a huge database can also be established for the historical data of the production process to ensure the quality of the product Trends, failure causes and past production status are analyzed and evaluated. the

The configuration of the management layer is: the S7 series communication module CP443-1 is connected to the PLC main controller 1, and the monitoring computer or server of each substation 4 is connected to the router through the Siemens industrial communication card CP1613A2, and the configuration of the monitoring computer or server The software is WinCC+SQLServer. the

The utility model has been exemplarily described above in conjunction with the accompanying drawings. Obviously, the specific implementation of the utility model is not limited by the above-mentioned method, as long as various improvements of the method concept and technical solutions of the utility model are adopted, or the utility model can be directly implemented without improvement.
