In the foregoing, the field monitoring platform, the field control platform and the data acquisition networking device are respectively communicated with the master station control module; the data acquisition networking device is used for transmitting the unit data to an external data server and/or a wireless terminal (the dotted line in fig. 1 indicates an external electrical connection relationship), the unit data can be data from a master station control module, 7 can also be data from a field monitoring platform and a field control platform, and certainly can be both the data and the data, and the utility model discloses do not limit this; the field monitoring platform and the field control platform are provided with visual human-computer interaction interfaces. Through the design, complicated and redundant measuring instruments are not needed, and effective monitoring and control can be carried out on the states, gating phases and detection curves of monitoring signals in real time through a visual human-computer interaction interface, so that the field application of operators is greatly facilitated. Particularly, different detection and rejection conditions can be embodied in different expression forms, real-time data can be associated with 3D visual simulation, and the management and control platform can be further provided with a fault expert diagnosis library for assisting operators to quickly search and solve the electrical fault of the system.

On the basis of the framework, the specific concept is a mode of distributed acquisition and centralized management, so that the high speed, stability and reliability of system data transmission can be ensured.
With regard to the specific communication modes of the aforementioned components, as shown in fig. 2, the present invention provides the following implementation references:
(1) the control module is internally communicated through an EtherCAT protocol, namely, the EtherCAT industrial Ethernet bus technology is adopted to realize the communication of all distributed I/O of the automatic bottom layer and the servo drive communication, the EtherCAT network-to-bottom is realized, the protocol processing is directly communicated to an I/O layer, any lower layer sub-bus is not needed, and no gateway delay is needed, and the single bus system can cover all equipment, so that the complex and high-speed control task of the equipment can be completed through the simplest network structure.
Regarding EtherCAT bus technology, EtherCAT (ethernet Control automation technology) is an open architecture, ethernet-based field bus system, and CAT is an abbreviation of the prefix of Control automation technology (Control automation technology). EtherCAT achieves a new height in network performance. The refresh period for 1000 distributed I/O data is only 30 mus, including the terminal cycle time. Up to 1486 bytes of process data, which corresponds almost to 12000 digital quantities of I/O, can be exchanged via an ethernet frame. And the transmission of this amount of data takes only 300 mus. Communication with 100 servo axes only takes 100 mus. During this time, settings and control data may be provided to all axes and their actual positions and states reported. The distributed clock technique ensures that the synchronization time between these axes deviates less than 1 microsecond.
By utilizing the excellent performance of the EtherCAT technology, a control method which cannot be realized by a traditional field bus system can be realized. Thus, a super high speed control loop can also be formed by the bus. Functions that the conventional electronic control system needs to be supported by local dedicated hardware can now be mapped in software, and huge bandwidth resources enable state data and any data to be transmitted in parallel. The EtherCAT technology enables the communication technology to be matched with modern high-performance IPC, a bus system is no longer the bottleneck of a control concept, and meanwhile data transmission of distributed I/O exceeds the performance which can only be realized by a local I/O interface.
This network performance advantage is evident in small controllers with relatively moderate computational power. The high speed loop of EtherCAT can be completed between two control loops. Thus, the controller always has the latest input data available, with minimal delay in output addressing. The response behavior of the controller is significantly improved without the need to enhance its own computational power.
(2) The master station control module communicates with the field monitoring platform, the field control platform and the data acquisition networking device through an ADS protocol to realize data acquisition, uploading, writing, issuing and monitoring. In order to make the data acquisition and transmission and the man-machine interaction efficient and stable, the communication between the IPC control layer and the man-machine interaction platform (namely the monitoring layer and the upper layer) can adopt an ADS communication protocol based on TCP/IP; the ADS communication protocol (automation device specification) of Beckhoff, as the transport layer of the system, was developed for data exchange between different software modules, such as communication between NC and PLC. The protocol provides a way to communicate with any variable of the control software program using other tools, such as the need to communicate with another PC or device, the ADS protocol is used over TCP/IP, which means that all data is available from the desired location in the communication network, and the communication protocol can complete one communication in a very short time (<10ms), thus being sufficient to ensure the efficiency and real-time of data information monitoring. In addition, in a possible implementation mode, by combining the actual layout and the equipment structure of the tobacco enterprise workshop, the master station control module can be respectively communicated with the field monitoring platform, the field control platform and the data acquisition networking device through an ADS (automatic dependent surveillance system) protocol through a switch, so that the efficiency and the stability of network bus transmission are ensured.
(3) The data acquisition networking device is communicated with an external data server through a TCP/IP protocol, namely, a stable and reliable mature network protocol can be used for exchanging with a site outside the system during implementation, and the design has the advantage that good and diverse external expansibility can be provided for the system conveniently.
(4) The data acquisition networking device can also carry out data interaction with an external remote terminal through mainstream wireless communication technologies such as 4G, 5G, WIFI, GPS and the like, and in the remote interaction process, external equipment reads unit-related parameter data in the machine treasure, such as but not limited to material consumption, quality alarm, equipment shutdown alarm, production data, machine speed, parameter adjustment of a quality detection system, production typesetting data, real-time data of a comprehensive test bench and the like, so that an operator can be clear at a glance on the production condition. For example, the APP in the mobile intelligent terminal of an operator and a manager pushes the state of a packaging production line, equipment fault information and the like, so that the purposes of remote monitoring, diagnosis and the like are achieved.
The aforementioned data acquisition networking device may specifically function to acquire, in real time, the operation parameters of the master station control module (which may also include the two monitoring platforms), and related information such as underlying data according to a preset policy, and unidirectionally transmit the information to an external data server and/or a wireless terminal. As mentioned above, the design framework of the system also takes the performance of outward expansion into consideration, so that the data can be docked to auxiliary connection equipment related to cigarette packet packaging by means of the data acquisition networking device in combination with the practical requirements of cigarette packet packaging operation.
Specifically, the data acquisition networking device is also provided with a plurality of communication interfaces which are in butt joint with external auxiliary networking equipment, and the system and an external system are interconnected and intercommunicated by utilizing the TCP/IP protocol. Wherein the auxiliary connection equipment comprises one or more of the following: a Manufacturing Execution System (MES), a comprehensive test platform, and a logistics System. And the system is in butt joint with an MES system, directly uploads related information such as quality information, rejection information, equipment alarm information, consumption information and the like of the single machine equipment to the MSE system, and then the related information is processed by the MES system and sent to related personnel terminals. The cigarette testing platform is connected with the comprehensive testing platform, an operator only needs to place the cigarettes into the testing platform, the testing platform automatically measures the cigarettes, measured data (index data such as cigarette weight, length, circumference, suction resistance and the like) can be transmitted to the intelligent management platform in real time, and the operator can timely calibrate equipment according to the data so as to meet production requirements. With the commodity circulation butt joint, this intelligent system of operating personnel accessible calls former auxiliary material to the commodity circulation in real time, and after calling, the automatic storage system of commodity circulation dispatches AGV pay-off dolly automatically, retrieves the empty auxiliary material tray of unit, then sends the former auxiliary material tray of commodity circulation allotment to call the auxiliary material unit to realize the automation of former auxiliary material and distribute.
The one-way is to reduce intrusion and influence of external equipment on the system while ensuring external expansibility, and the data acquisition networking device can receive and transmit relevant data from the inside of the system, but the data acquisition networking device does not send data to the bottom layer of the IPC control layer, so that the data acquisition networking device is used as a one-way data isolation device to ensure the safety of the data at the bottom layer of the system.
Based on the above concept, in a preferred implementation, the data collection networking device may include a Ceres robot. As the data acquisition networking device of the edge computing layer, the data acquisition networking device can be realized by adopting the existing intelligent hardware-Ceres robot in actual operation, the data robot can realize the functions of data acquisition, data analysis, data classification, data access, data transmission, data interface management, interaction and the like in an integrated mode, and meanwhile, the robot integrates the advanced communication technologies of Internet + mobile interaction and the like, so that the integration and the data interaction with a tobacco enterprise management system can be effectively enhanced. That is to say, the main effect of the machine treasure is as a bridge for data acquisition and equipment bottom layer data exchange, IPC bottom layer data can be sent to the machine treasure in real time according to user requirements through program compiling, protocol matching and parameter setting, and a data processor, an MES and the like can continuously refresh data from the machine treasure.
Furthermore, to the utility model provides a tobacco bale packagine machine group control system's safety control demand, in the embodiment of a preferred aforesaid control assembly can also including locate in the main electric cabinet, and with master station control module electricity signal connection's safety controller, safety controller has multichannel IO passageway. Therefore, the system integrates automatic control, servo control (each station execution end) and safety control, integrally improves the reliability and compatibility of the system, and can reduce the error of the packaging unit in continuous production to minimum. In actual operation, a safety controller such as TwinSAFE may be employed to achieve plant-related safe operation control; moreover, for the same purpose, it can be considered that all the terminal modules of the main electric control cabinet and the sub electric control cabinet can have self-diagnosis functions, so that the safety and maintainability of the system can be further improved.
As mentioned in the foregoing, foreign equipment suppliers use dedicated software languages to program, which greatly hinders the deep mastering and technical iteration of technicians in our country, therefore the present invention proposes in a better implementation manner that the control assembly is compatible with a plurality of universal programming languages, which can include ST structure text programming languages based on IEC61131-3 standard, that is, the present invention discloses a control software that can use simple and modular standard structures, so that technicians in our country can quickly and efficiently program corresponding control processes for their own actual needs. Accordingly, the present invention further provides a software system reference that is today relatively mature and easy to use, i.e., the control component may be configured with a TwinCAT software system. This twinCAT system possesses multinuclear multithread processing technique, and every second can handle twenty thousand data points to have the high compatible characteristic of preferred, with the utility model discloses an original intention complements each other.
Synthesize the distribution I/O design and aforementioned control software system of above-mentioned net on end, the utility model provides a can replace traditional "MICRO II" type electrical system's special parts through software algorithm to this reduce system cost improves the system stability, realizes the quick update iteration of part key function.

In other words, the system can realize the control requirement of the traditional foreign system by a structural framework of master-slave network communication and by a software programming mode and a standardized industrial control product, and greatly saves special hardware adopted in the foreign existing control system, for example, motion signals of acquired key components can be directly sent to a master station control module through each I/O slave station through an Ethernet for processing and feeding back action instructions.
In combination with actual components of the existing packaging unit, the unit adopts three absolute value encoders to determine the phase of the machine, so that the mechanical phase and the electrical phase of the machine are accurately matched without error, the control precision and the performance of the machine are improved to the maximum extent, and the quality detection of each item of the machine is ensured to be accurately completed. After the binary code measured by the absolute value encoder is converted into an angle due to the high precision of the absolute value encoder (the error of each circle is one thousandth), the error between the main motor and the rest of motors is low, the accuracy of each station connecting rod mechanism and the accuracy of the rotating speed between the motors are guaranteed, and the accuracy of conveying and cutting lengths of original and auxiliary materials is guaranteed. Therefore, the absolute encoder is used for carrying out real-time following speed measurement on the transmission of the main motor of the machine, and the most reasonable matching between electromechanics is ensured.
However, in the conventional electric control system, the binary code acquired by the encoder needs to be transmitted to a dedicated encoder board card provided by a foreign equipment supplier, and then converted into an angle and speed signal through hardware processing of the encoder board card, and then sent to the CPU to control the movement of key parts of the equipment.
