[0003] The current automatic operation system lacks corresponding node control function and data protection function, and the node control function can indeed cause the specific device and specific link of slow operation progress to be found in time, thereby slowing down the overall operation progress, and the lack of data protection function can cause enterprise data to be leaked, and the network security in the control process has certain risks, therefore, designing an automatic operation system with data protection function and node control function is a technical problem to be solved by the person skilled in the art. SUMMARY

[0004] In view of the deficiencies of the prior art, the present application provides an automatic operation integrated control system, which solves the problems raised in the background art.

[0005] To achieve the above purpose, the present application is realized by the following technical scheme: an automatic operation integrated control system, comprising a maintenance station client, a server data center, a data supervision platform, a master station, a total control touch screen, a first slave station, a second slave station, a third slave station, a fourth slave station, a fifth slave station, an unloading device, a cleaning center, an automatic warehouse filling and distributing machine, a flat storage machine, an out-of-warehouse machine, an I / O module and a coupler, the ports of the master station are respectively in communication with the ports of the maintenance station client, the server data center and the data supervision platform, the port of the master station is in communication with the port of the total control touch screen, the ports of the master station are respectively in communication with the ports of the I / O module and the coupler, the ports of the master station are respectively in communication with the ports of the first slave station, the second slave station, the third slave station, the fourth slave station and the fifth slave station, the port of the first slave station is in communication with the port of the unloading device, the port of the second slave station is in communication with the port of the cleaning center, the port of the third slave station is in communication with the port of the automatic warehouse filling and distributing machine, the port of the fourth slave station is in communication with the port of the flat storage machine, and the port of the fifth slave station is in communication with the port of the out-of-warehouse machine.

[0006] The interconnection and interworking between the terminals of automatic unloading machines, centralized cleaning centers, automatic distributing machines, automatic out-of-warehouse machines and the like are realized; integrated control algorithms, collaborative control optimization methods and design human-computer interaction interfaces are researched, centralized control systems, video communication systems, operation monitoring systems and early warning information systems are constructed, fault handling strategies are proposed, integrated control of the operation line is realized, and the system is efficiently and reliably operated;

[0007] The internal centralized control system of the operation line has multiple single machines, and most of the single machines are controlled by PLC. In order to meet the requirements of automatic in-and-out-of-warehouse, some devices have an upper computer operating system, and some single instruments do not have an upper computer but only have a control component. Therefore, the central control system adopts an upper computer-upper computer and a lower computer-lower computer communication mode to ensure stable operation of device communication.

[0008] The maintenance station client is used for device maintenance personnel to operate, remotely monitor system operation, query device fault records, configure parameters and debug programs. The server data center undertakes data storage, processing and management tasks, and aggregates data uploaded by the master station and each module. The data supervision platform performs real-time monitoring, analysis and supervision on system data, establishes a basic node, and alarms in case of abnormality. The I / O module is responsible for collecting on-site device on-off signals and analog signals, and outputting control signals. The coupler is used for signal conversion and transmission adaptation. The master station serves as the core control unit of the system, coordinates and manages each slave station, receives upper platform instructions, distributes tasks to slave stations, aggregates slave station data and uploads them. The total control touch screen is a field operation interaction interface. The operator can check the real-time state of the system and device parameters, switch modes, start and stop devices, etc. through it. The first slave station, the second slave station, the third slave station, the fourth slave station and the fifth slave station are responsible for controlling unloading equipment, cleaning centers, automatic warehouse filling and distributing machines, flat warehouse machines and out-of-warehouse machines in turn. The unloading equipment is used to perform unloading operations. The cleaning center performs cleaning operations on raw grain. The automatic warehouse filling and distributing machine is used for warehouse filling and distributing operations of raw grain. The flat warehouse machine is used for flat warehouse processing of raw grain. The out-of-warehouse machine is used to transport raw grain.

[0009] Further, when the data supervision platform supervises, the data supervision platform establishes a basic node for the first slave station, the second slave station, the third slave station, the fourth slave station and the fifth slave station respectively, each basic node corresponds to a work flow stage of an equipment, the basic nodes of the unloading equipment corresponding to the first slave station are in turn transportation start, arrival target point, start unloading, unloading reaching 50% and complete unloading, the basic nodes of the cleaning center corresponding to the second slave station are in turn setting screening specification, setting screening air pressure, determining conveying speed, starting cleaning, cleaning reaching 50% and completing cleaning, the basic nodes of the automatic warehousing distributor corresponding to the third slave station are in turn setting conveying amount, setting warehousing volume, starting conveying, conveying reaching 50% and completing distribution, the basic nodes of the flat warehouse machine corresponding to the fourth slave station are in turn scanning flat warehouse range, path planning, starting flat warehouse, flat warehouse reaching 50% and completing flat warehouse, and the basic nodes of the warehouse outlet machine corresponding to the fifth slave station are in turn setting warehouse outlet amount, setting grain outlet speed, starting grain outlet, grain outlet reaching 50% and completing warehouse outlet;

[0010] When the first slave station, the second slave station, the third slave station, the fourth slave station and the fifth slave station execute any one basic node, the executed basic node content is marked as feedback information and is uniformly transmitted to the master station, the master station transmits the feedback information to the data supervision platform, the data supervision platform establishes a work flow progress table, and the data supervision platform inputs the received feedback information into the work flow progress table for data display.

[0011] The data supervision platform sets a total flow control process, the total flow control process monitors the time interval of each basic node of each slave station in real time, judges whether the flow progress is slow, and executes an execution node refinement program if the flow progress is slow.

[0012] Further, the judgment content of the total flow control process is as follows:

[0013] The total process control process acquires and marks the time of each basic node in real time, the total process control process calculates the time interval between each basic node in each slave station, the total process control process calculates the time interval between each basic node between the slaves, the total process control process saves the calculation result to the server data center, the total process control process recalculates the interval average value of the interval time between the basic nodes each time the interval time between the basic nodes is saved, the total process control process sets the first warning threshold and the second warning threshold, if the newly saved time interval of the basic node divided by the interval average value is lower than the first warning threshold or the newly saved time interval of the basic node divided by the interval average value of the previous three times is lower than the second threshold, it represents that the time interval of the basic node is too long, the process progress is slow, and the first warning threshold represents that the time interval of the basic node is too long, and the second warning threshold represents that the time interval of the basic node is too long in the whole process of the time period from the basic node to the previous three basic nodes, and the data supervision platform executes node refinement program to analyze the specific time point of slow process progress.

[0014] Further, when the node refinement program is executed, the data supervision platform marks the basic node of the triggered program and the two adjacent basic nodes before and after as a refinement area, the data supervision platform sets a third warning threshold, the data supervision platform sets a plurality of secondary nodes in the refinement area, the number of secondary nodes ranges from 4 to 100, the data supervision platform issues the secondary nodes to the corresponding slave station, and the slave station equally divides the refinement area according to the number of secondary nodes.

[0015] After the equal division is completed, the refinement area determines the specific time point of slow process progress and improves the display weight W of the specific time point of slow process progress.

[0016] Further, the display weight adjustment process of the specific time point of slow process progress is as follows:

[0017] The data supervision platform acquires the number of secondary nodes in the slave station corresponding to the specific time point of slow process progress and marks it as k, the data supervision platform sets a weight factor w, and the data supervision platform calculates the display weight W of the specific time point of slow process progress according to the formula The greater the value of k represents the more content needs to be displayed, so the marginal effect needs to be used to limit the display weight W to avoid occupying too much area and losing the rest of the information, and the weight factor w is the initial value of the display weight W to avoid too small display area to achieve the warning effect.

[0018] Further, the determination process of the specific time point of slow process progress is as follows:

[0019] The trigger node refinement procedure corresponds to the slave station recording the time of each secondary node again in real time and saving to the server data center through the master station, the data supervision platform calculates the interval time between the newly saved secondary nodes in real time, if the time interval difference ratio between each secondary node is less than the third warning threshold, it represents that the number of added secondary nodes is not enough, and it cannot accurately locate the slow progress time point, the data supervision platform inserts new secondary nodes between each secondary node, and recalculates the time interval difference ratio between each secondary node after inserting new secondary nodes until any one time interval difference ratio is greater than or equal to the third warning threshold or reaches the upper limit of the number of secondary nodes, if any one time interval difference ratio is greater than or equal to the third warning threshold, the data supervision platform marks the secondary node triggering the third warning threshold as the specific time point of slow progress, if the number of secondary nodes reaches the upper limit, the data supervision platform selects the secondary node with the longest time interval to mark as the specific time point of slow progress, and the data supervision platform increases the display weight W of the specific time point of slow progress.

[0020] Further, the data supervision platform establishes a key library, which is composed of a plurality of different keys, and arranges the plurality of keys into an array, with the first reference as the horizontal coordinate and the second reference as the vertical coordinate, and the numerical range of the first reference and the second reference being 0-9. By knowing the specific values of the first reference and the second reference, the corresponding key can be determined.

[0021] The data supervision platform determines the value of the first reference based on the instruction time issued by the first slave station, the second slave station, the third slave station, the fourth slave station and the fifth slave station, and determines the value of the second reference based on the time of completing the corresponding work of the equipment in each slave station. The time of completing the work includes the time of completing each basic node, and the recorded instruction time and the time of completing the corresponding work of the instruction are both transmitted in plaintext, and all the time of transmitting in plaintext is saved to the server data center. The data communication between the maintenance station client, the server data center, the data supervision platform, the master station, each slave station and the corresponding equipment of the slave station is encrypted through the key library.

[0022] Further, the first reference determination process is as follows:

[0023] The data supervision platform retrieves the time corresponding to the issued instruction from the server data center, and the data supervision platform extracts the last value of the hour, minute and second in the time and adds them up, and takes the last value after addition as the first reference.

[0024] Further, the second reference determination process is as follows:

[0025] The data supervision platform calls the time of job completion from the server data center, extracts the last value of the time of completion of each basic node, subtracts the absolute value of all extracted last values, and marks the last value of the absolute value as the second reference.

[0026] Further, the data supervision platform sets a protection mechanism for all encrypted data, and when any device uses a key in the key library to decrypt the encrypted data, the data supervision platform limits the number of decryption times, and after exceeding the number of decryption times, the decrypted data is automatically destroyed, avoiding the use of the exhaustive method to force crack the encrypted data.

[0027] The present application has the following beneficial effects:

[0028] 1. By setting the basic node and the secondary node, the fine control of each job flow can be realized, and the slow progress of the device or the time point can be found in time, which can help the enterprise to optimize the job flow, and the display weight can be set to preferentially display the local progress of the slow progress, and the attention of the enterprise can be improved in time.

[0029] 2. By setting the array key, the specific key is determined by the time in different states, which can effectively improve the security of the data and avoid data leakage, and even if the key is intercepted, the protection mechanism can also avoid the force cracking of the encrypted data.

[0030] Of course, any product implementing the present application does not necessarily need to achieve all the advantages described above. BRIEF DESCRIPTION OF DRAWINGS

[0034] Embodiment one

[0035] See also Figure 1 The present invention provides a technical solution: an integrated control system for an entire automated operation line, comprising a maintenance station client, a server data center, a data monitoring platform, a master station, a master control touch screen, a first slave station, a second slave station, a third slave station, a fourth slave station, a fifth slave station, grain unloading equipment, a cleaning center, an automatic loading and distributing machine, a flattening machine, a warehouse discharge machine, an I / O module, and a coupler.

[0036] The maintenance station client is used by equipment maintenance personnel to remotely monitor system operation, query equipment fault records, configure parameters and debug programs, facilitate timely response and processing of equipment maintenance needs, and ensure stable system operation. The server data center undertakes data storage, processing and management tasks, summarizes data uploaded by the main station and each module, provides data support for system analysis and decision-making, realizes long-term retention and traceability of production data, and helps optimize production processes. The data supervision platform monitors, analyzes and supervises system data in real time, establishes basic nodes, and alarms in case of abnormalities. It is used to control production quality, ensure production compliance, and assist managers in grasping the overall operation status. The I / O module is responsible for collecting switch and analog signals of field equipment and outputting control signals. The coupler is used for signal conversion and transmission adaptation to ensure stable signal interaction between the main station and external equipment. The master station serves as the core control unit of the system, coordinates and manages each slave station, receives instructions from the upper platform, assigns tasks to the slave station, summarizes the slave station data and uploads it, so as to realize centralized control and scheduling of the entire line operation. The master control touch screen is the on-site operation interactive interface, through which the operator can view the real-time status of the system, equipment parameters, perform mode switching, equipment start and stop and other operations, which is convenient for rapid on-site intervention and control. The first slave station, the second slave station, the third slave station, the fourth slave station and the fifth slave station are responsible for controlling the unloading equipment, the cleaning center, the automatic loading and spreading machine, the flattening machine and the outbound machine in turn. The unloading equipment is used to perform unloading operations, and the cleaning center cleans the raw grain to avoid impurities in the raw grain. The automatic loading and spreading machine is used for loading and spreading operations of the raw grain, the flattening machine is used for flattening the raw grain, which also helps in subsequent outbound operations, and the outbound machine is used to transport the raw grain.

[0037] The data supervision platform establishes a basic node for the first slave station, the second slave station, the third slave station, the fourth slave station and the fifth slave station when the data supervision platform supervises, each basic node corresponds to a work flow stage of an equipment, the basic nodes of the unloading equipment corresponding to the first slave station are in turn transportation start, arrival at target point, start unloading, unloading reaching 50% and completion of unloading, the basic nodes of the cleaning center corresponding to the second slave station are in turn setting screening specification, setting screening air pressure, determining conveying speed, starting cleaning, cleaning reaching 50% and completion of cleaning, the basic nodes of the automatic warehousing material distribution machine corresponding to the third slave station are in turn setting conveying amount, setting warehousing volume, starting conveying, conveying reaching 50% and completion of material distribution, the basic nodes of the flat warehouse machine corresponding to the fourth slave station are in turn scanning flat warehouse range, path planning, starting flat warehouse, flat warehouse reaching 50% and completion of flat warehouse, and the basic nodes of the warehouse outlet machine corresponding to the fifth slave station are in turn setting warehouse outlet amount, setting grain outlet speed, starting grain outlet, grain outlet reaching 50% and completion of warehouse outlet;

[0038] When the first slave station, the second slave station, the third slave station, the fourth slave station and the fifth slave station execute any one basic node, the content of the executed basic node is marked as feedback information and is uniformly transmitted to the master station, the master station transmits the feedback information to the data supervision platform, the data supervision platform establishes a work flow progress table, and the data supervision platform inputs the received feedback information into the work flow progress table for data display.

[0039] The data supervision platform sets a total flow control process, the total flow control process monitors the time interval of each basic node of each slave station in real time, judges whether the flow progress is slow, and executes an execution node refinement program if the flow progress is slow.

[0040] The judgment content of the total flow control process is as follows:

[0041] The total process control process acquires and marks the time of each basic node in real time, and the total process control process calculates the time interval between each basic node in each slave station, and the total process control process calculates the time interval between each basic node between the slaves, and the total process control process saves the calculation result to the server data center, and the total process control process recalculates the interval average of the interval time each time the time interval between the basic nodes is saved, and the total process control process sets the first warning threshold 95% and the second warning threshold 85%, respectively. If the newly saved basic node time interval divided by the interval average is lower than the first warning threshold, or the newly saved basic node time interval divided by the interval average of the previous three times is lower than the second threshold, it represents that the time interval of the basic node is too long, and the process progress is slow. Below the first warning threshold represents that the time interval of the basic node is too long, and below the second warning threshold represents that the time interval of the basic node is too long in the overall process of the time period from the basic node to the previous three basic nodes. In any case, it represents that the progress of the basic node is slow, and needs to be warned and improve the supervision attention, and the data supervision platform executes the node refinement program to analyze the specific time point of slow process progress.

[0042] Wherein, when the node refinement program is executed, the data supervision platform marks the basic node of the triggered program and the two adjacent basic nodes before and after as a refinement area, the data supervision platform sets a third warning threshold of 10%, and the data supervision platform sets a plurality of secondary nodes in the refinement area, the number of secondary nodes ranges from 4 to 100, and 4 is the initial number of secondary nodes. The data supervision platform issues the secondary nodes to the corresponding slave station, and the slave station equally divides the refinement area according to the number of secondary nodes;

[0043] After the equal division is completed, the refinement area determines the specific time point of slow process progress and increases the display weight W of the specific time point of slow process progress. By setting the basic node and the secondary node, the fine control of each job process can be realized, and the slow progress of the equipment or the time point can be found in time, which can help the enterprise to optimize the job process. Setting the display weight can preferentially display the local progress of the slow progress, and timely warning can improve the attention of the enterprise.

[0044] Wherein, the display weight adjustment process of the specific time point of slow process progress is as follows:

[0045] The data supervision platform acquires the number of secondary nodes in the slave station corresponding to the specific time point of slow process progress, marks it as k, sets the weight factor w as 0.1, and calculates the display weight W of the specific time point of slow process progress according to the formula The greater the value of the display weight W of the specific time point of slow progress of the process is, the more content needs to be displayed, so the marginal effect is used to limit the display weight W to avoid occupying too much area and causing the loss of remaining information. The weight factor w is the initial value of the display weight W to avoid a too small display area that cannot achieve the warning effect.

[0046] The specific time point of slow progress of the process is determined as follows:

[0047] The slave station corresponding to the trigger node refinement program records the time of each secondary node again in real time and saves it to the server data center through the master station. The data monitoring platform calculates the interval time between the newly saved secondary nodes in real time. If the time interval difference ratio between each secondary node is less than the third warning threshold, it means that the number of added secondary nodes is not enough to accurately locate the slow progress time point. The data monitoring platform inserts new secondary nodes between each secondary node, for example, the original number of secondary nodes is n, and after adding new secondary nodes, the number is 2n-1. After adding new secondary nodes, the time interval difference ratio between each secondary node is recalculated until any time interval difference ratio is greater than or equal to the third warning threshold or reaches the upper limit of the number of secondary nodes. If any time interval difference ratio is greater than or equal to the third warning threshold, the data monitoring platform marks the secondary node of the third warning threshold as the specific time point of slow progress of the process. If the number of secondary nodes reaches the upper limit, the data monitoring platform selects the secondary node with the longest time interval as the specific time point of slow progress of the process. The data monitoring platform increases the display weight W of the specific time point of slow progress of the process.

[0048] The data monitoring platform establishes a key library, which is composed of a plurality of different keys. The data monitoring platform arranges the plurality of keys into an array, with the first reference as the horizontal coordinate and the second reference as the vertical coordinate. The value range of the first reference and the second reference is 0-9. The specific value of the first reference and the second reference can determine the corresponding key.

[0049] The data supervision platform determines the first reference value according to the instruction time issued by the first slave station, the second slave station, the third slave station, the fourth slave station and the fifth slave station, and determines the second reference value according to the time of completing the corresponding work of the instruction of each slave station, and the time of completing the work includes the time of completing the work of each basic node; the issued instruction time and the time of completing the corresponding work of the instruction are both transmitted in plaintext, and all the time of transmitting in plaintext is saved to the server data center; the data communication between the maintenance station client, the server data center, the data supervision platform, the master station, each slave station and the corresponding device of the slave station is encrypted through the key library, the specific key is determined by setting the array key and using the time in different states, so that the security of the data can be effectively improved, and data leakage can be avoided; even if the key is intercepted, the protection mechanism can also avoid the encrypted data from being brute-forced.

[0050] The first reference determination process is as follows:

[0051] The data supervision platform retrieves the corresponding time of the issued instruction from the server data center, the data supervision platform extracts the last value of the hour, minute and second in the time and adds them, and the last value after addition is marked as the first reference.

[0052] The second reference determination process is as follows:

[0053] The data supervision platform retrieves the time of completing the work from the server data center, the data supervision platform extracts the last value of the time of completing the work of each basic node, the data supervision platform subtracts all the extracted last values to obtain the absolute value, and the last value after extracting the absolute value is marked as the second reference.

[0054] The data supervision platform sets a protection mechanism for all the encrypted data, and when any device uses the key in the key library to decrypt the encrypted data, the data supervision platform limits the number of decryption to 3 times, and after the number of decryption is exceeded, the decrypted data is automatically damaged to avoid using the exhaustive method to brute-force the encrypted data.

[0058] The total control touch screen carries the operation detection system and the man-machine interface, the operation detection system and the man-machine interface are composed of operation picture, monitoring picture and display picture, each slave station is matched with corresponding monitoring camera, the monitoring picture monitors the overall operation situation in the operation line through the monitoring camera and sensor, the system operation picture of each slave station is provided by corresponding device, each device can also be controlled on the page of the total control touch screen, the display picture uses digital twin technology to build three-dimensional model of the operation line, sensors for feeding back device execution information are installed in each corresponding device of the slave station, according to the execution information fed back by each execution device of the operation line operation device, real-time synchronization is carried out to the three-dimensional model, visual display is carried out, the three-dimensional model not only can real-time display the working state of various devices in each module, but also can modularize each component, when each module fails, the fault information can be displayed, the fault module can be accurately positioned through the fault early warning information, and the three-dimensional model is also displayed;

[0059] The fault early warning system accesses the control system of the master station through I / O module and coupler, the fault early warning man-machine interface has a separate module to display early warning information, which is convenient for managers to know the device fault situation in time, according to the service life of the device running times and running time provided by the device manufacturer, a device life cycle management database is established, the device life cycle management database is saved in the server data center, the background can real-time view the life state of each running device, and the device state can be real-time displayed on the three-dimensional model in the future:

[0060] In the control system of the master station and the slave station, the information received by the master station from the slave station is shown in Table 1 as follows:

[0061] Table 1: Running state and signal parameter table

[0062]

[0063] Wherein, each slave corresponding single machine equipment is equipped with work mode knob and emergency stop reset button, work module includes three kinds of local mode, automatic mode and remote mode, in local mode, single machine can be automatically operated and manually operated, in automatic and remote mode, it is taken over by central control system, in automatic mode, it waits for central control system instruction to run system, in remote mode, manual signal is sent by central control system to realize manual operation, after fault handling, single machine can be reset by reset button, equipment working state, each single machine module needs to feedback central control system equipment working state, when equipment is 0, it indicates that single machine is in idle standby state, 1 indicates that single machine equipment is in automatic operation, 2 indicates that single machine equipment is in fault, there is alarm signal inside, 3 indicates that single machine emergency stop button triggers emergency stop state, equipment fault signal, single machine equipment needs to detect internal devices, such as dust removal fan power supply detection fault, hydraulic butterfly valve opening and closing detection fault, hydraulic rod initial and initial position detection fault, all internal devices of single machine need to have sensor signal feedback, such as telescopic mechanism needs to have initial position and initial position detection, motor needs to have locked-rotor detection and speed detection, equipment material conveying needs to have material flow detection, single machine system module needs to feedback total running time and running times of each execution component according to equipment running condition, such as proximity switch use time, axial flow fan running time, hydraulic valve on-off times and other information.
