[0002] Smart factory management is an innovative factory management solution that aims to achieve comprehensive monitoring and optimization of factory equipment, production processes and energy consumption by integrating multiple advanced technologies and modules. Smart factory management involves multiple controls, mainly the control of factory equipment. In the existing smart factory management control, the master control system often controls the factory equipment after data analysis. However, in fact, a single control method will cause all data to be put into the master control for processing, which will increase the burden on the master control system and bring inconvenience to equipment control. Similarly, other single equipment control methods are difficult to adapt to all scenarios, resulting in inaccurate control solutions, reducing the benefits brought by equipment operation or increasing costs during factory operation.

[0011] Preferably, the step of obtaining the decision-making experience of the operator and confirming the controller from the master control system and the operator is specifically: Determine whether the operator has the authority to view the necessary information.

[0017] Figure 1 It is a schematic diagram of specific steps of an embodiment of a control method for smart factory affairs of the present invention.

[0018] Figure 2 It is a module connection diagram of an embodiment of a control system for smart factory affairs of the present invention. DETAILED DESCRIPTION

[0019] Below is a combination of the embodiments and Figure 1-Figure 2 The present invention is further described in detail, but the embodiments of the present invention are not limited thereto.

[0020] The present invention discloses a control method for smart factory affairs, which specifically comprises the following steps: Step S1, collecting data of machinery and equipment in the factory and recording it as equipment data, and storing the equipment data.

[0021] Different machines and devices store the data generated during operation in a unified manner in the memory.

[0022] Step S2, extracting parameter data from the device data, obtaining the device that needs to be adjusted according to the parameter data and recording it as the adjusted device.

[0023] Step S3, extracting necessary information for adjusting the operation of the equipment from the equipment data, obtaining the equipment corresponding to the necessary information and recording it as an associated equipment.

[0024] Step S4, obtaining the sensitivity of the necessary information, judging whether to open the data transmission channel between the associated device and the adjustment device according to the sensitivity of the necessary information, and obtaining a transmission judgment result.

[0025] Step S5, obtaining the usage rate of the necessary information, and confirming the controller from the adjustment equipment, the master control system and the operator in combination with the transmission judgment result.

[0026] Step S6, obtaining the corresponding decision given by the controller and using it as the control decision, and the machine equipment executes the control decision.

[0027] The controller makes the corresponding decision, and the machine equipment executes the decision. For example, if the controller is the adjustment equipment, then the adjustment equipment obtains the required data from other equipment and adjusts the parameters according to the required data. For example, the previous machine equipment shapes the product, and the adjustment equipment needs to polish the product at this time. Then the product size is obtained according to the shaping size of the previous equipment, and the polishing parameters are adjusted to suit the product size. If the controller is an operator, the control decision is executed according to the operator's manual operation. If the controller is the master control system, the plan is executed according to the control instructions sent by the master control system.

[0028] In actual use, there are many machines and equipment in the factory, and the control methods of these equipment are also diverse. The equipment can be self-controlled, controlled by the master control system, or controlled by human operation. Different control methods have their own advantages and disadvantages. For the factory's machinery and equipment, using a single control method to control the machinery and equipment is not conducive to the convenient operation of the equipment. Selecting different controllers in different situations and executing corresponding control decisions is conducive to improving the accuracy of machine control and improving the efficiency of machine equipment operation. For example, when the equipment is automatically controlled, some data is needed for judgment, so as to give a control plan. However, due to the high sensitivity of some data, the equipment cannot call the required data. At this time, the equipment cannot achieve automatic control, and other control methods need to be selected to reduce the risk of data leakage.

[0029] Extract parameter data from the device data, obtain the device that needs to be adjusted according to the parameter data and record it as the steps for adjusting the device, specifically: Step S21, obtaining the operation process of the factory affairs, searching for the equipment corresponding to the operation process according to the operation process, and forming an equipment flow chart.

[0030] Step S22, obtaining production requirements, and setting standard parameters of different equipment according to the production requirements and the equipment flow chart.

[0031] Step S23, extracting the real-time parameters of the equipment operation in the equipment data, comparing the standard parameters with the real-time parameters of the corresponding equipment, and obtaining the parameter difference value.

[0032] Step S24, screening out devices that need to adjust parameters according to the parameter difference values ​​to form an adjustment device set.

[0033] The parameter difference value threshold is set according to the allowable error of different devices. When the parameter difference value of the device reaches the parameter difference value threshold, it is determined that the device needs to be adjusted.

[0034] Step S25, setting the adjustment priorities of different devices, and selecting the adjustment device with the highest adjustment priority as the adjustment device.

[0035] Set the device adjustment priority according to the impact of not adjusting the device. The higher the impact of the device, the greater the adjustment priority.

[0036] In actual use, there are many machines and equipment in the factory, each of which has its own functions. These machines and equipment are interrelated, and one move affects the whole body. Therefore, the equipment needs to be controlled and adjusted during operation. The operation of the equipment usually has a standard process, and it can be adjusted according to production needs to obtain the standard parameters that the equipment should be set. For example, in a popsicle manufacturing plant, the sizes of popsicles are different, and the sizes of the packaging bags produced during the packaging process are different. At the same time, the intervals for sealing the packaging after packaging are different, and the time intervals for staying during the packaging process are also different. According to the changes in production needs, the specific parameters that need to be set for the equipment can be known. If the real-time parameters and standard parameters are within the standard error, no adjustment is required. If they are not within the standard error, the equipment needs to be adjusted. After adjusting the equipment with the best priority level, update the equipment data.

[0037] The steps of extracting the necessary information for adjusting the operation of the equipment from the equipment data, obtaining the equipment corresponding to the necessary information and recording it as the associated equipment are as follows: Step S31, obtaining reference information of the adjustment device in the process of adjusting parameters, and dividing the type of the reference information into device reference data type and non-device reference data type according to the judgment basis of whether the reference information is obtained through device data.

[0038] Adjusting equipment parameters is not blind adjustment, but needs to be based on certain data. For example, when the transmission speed of the popsicle is 1 meter per second, the packaging frequency of the packaging equipment is 1 second per time. When the transmission speed of the popsicle is 2 meters per second, the packaging frequency of the packaging equipment needs to be changed, otherwise the popsicle cannot be accurately packaged. At this time, the reference information of the packaging equipment is the data of the transmission equipment of the popsicle.

[0039] Step S32, extracting device data that conforms to the device reference data type from the device data and recording it as necessary information, obtaining the device corresponding to the necessary information and recording it as an associated device.

[0040] In actual use, the machines and equipment in the factory are interrelated. Deviations or adjustments in the operation of some equipment will cause parameter adjustments of other equipment. The parameter adjustment of the equipment also needs to consider the operating parameters of other equipment to better achieve the collaborative work between the factory machines and equipment. Some data does not rely on other equipment to obtain, so it is considered that it can be obtained directly and has no association with other equipment. Information associated with other equipment is recorded as necessary information, which is conducive to the transmission of subsequent data.

[0041] The steps of obtaining the sensitivity of the necessary information, judging whether to open the data transmission channel between the associated device and the adjustment device according to the sensitivity of the necessary information, and obtaining the transmission judgment result are specifically as follows: Step S41, obtaining the sensitivity of the necessary information, obtaining the transmission environment data, and determining the sensitivity threshold according to the transmission environment data.

[0042] The sensitivity of the required information can be evaluated by its information entropy or its availability. Data with high information entropy usually contains more uncertainty and complexity, and therefore has higher sensitivity. Data availability refers to the accessibility and integrity of data. Data with high availability is usually easier to access and use, and therefore may have higher sensitivity.

[0043] Step S42, determining whether the sensitivity of the necessary information is greater than a sensitivity threshold. If it is greater than the sensitivity threshold, the data transmission channel between the associated device and the adjustment device is not opened, and a transmission determination result is obtained.

[0044] Step S43: If it is not greater than the sensitivity threshold, determine whether the device data of the associated device and the adjustment device are compatible.

[0045] Step S44: If they are not compatible, the data transmission channel between the associated device and the adjustment device is not opened, and a transmission judgment result is obtained.

[0046] Step S45: If compatible, the data transmission channel between the associated device and the adjustment device is opened, and a transmission judgment result is obtained.

[0047] In actual use, in some controls such as distributed control, there are often data islands, and data cannot be transmitted and shared between different devices. Sharing data between devices has advantages and disadvantages, and data islands do not always bring negative effects. Obviously, data sharing between devices can achieve automatic control of devices, and the response speed will be faster than the control of the total system. However, data sharing between devices will also increase the risk of data loss and leakage. Therefore, whether to open the transmission channel between the associated device and the adjustment device depends on the actual situation. If the data sensitivity is high, the transmission channel will not be opened, and data cannot be shared between devices, reducing the negative consequences of data leakage. If the data sensitivity is not high, it is necessary to determine whether the data of the two devices are compatible. If not, it will also increase the burden of data processing on the device, and it is more likely that the device will not be able to process the data after receiving it. Therefore, not sharing data is beneficial to the operation of factory affairs.

[0048] The steps of obtaining the sensitivity of the necessary information, obtaining the transmission environment data, and determining the sensitivity threshold according to the transmission environment data are as follows: Step S411, acquiring transmission environment data, where the transmission environment data includes basic transmission environment data and personnel transmission environment data.

[0049] Step S412: The basic transmission environment data includes the leakage frequency of the necessary information and the attack frequency of the data transmission channel.

[0050] Step S413, obtaining a first transmission security value according to the leakage frequency of the necessary information and the attack frequency of the data transmission channel.

[0051] The weight ratios of the leakage frequency and the frequency of the data transmission channel being attacked are respectively set, and the first transmission safety value is calculated according to the leakage frequency, the frequency of the data transmission channel being attacked and the corresponding weight ratios.

[0052] Step S414: the personnel transmission environment data includes an operator distribution map and operator authority, and a second transmission safety value is obtained according to the operator distribution map and the operator authority.

[0053] Step S415, superimposing the first transmission security value and the second transmission security value to obtain a transmission security value, and searching a preset transmission security value-sensitivity threshold table to obtain a corresponding sensitivity threshold.

[0054] In actual use, on the one hand, data leakage is related to the security settings of the data transmission channel, such as whether the network is stable, whether there is a firewall, etc. The higher the leakage frequency, the less secure the transmission channel settings are. The higher the frequency of attacks on the data transmission channel, the greater the risk of data theft, so the basic transmission risk is higher. The transmission security value-sensitivity threshold table sets the acceptable sensitivity thresholds corresponding to different transmission security values. The higher the transmission security value, the higher the corresponding sensitivity threshold, because the transmission is safer, so highly sensitive data can be transmitted. The lower the transmission security value, the lower the corresponding sensitivity. Since the risk of data leakage is greater, in order to reduce the negative consequences of data leakage, only some data with lower sensitivity can be transmitted.

[0055] The step of obtaining the second transmission safety value according to the operator distribution map and the operator authority is specifically as follows: Step S4141, judging whether the operator has the authority to view the necessary information according to the operator's authority, if the operator has the authority to view the necessary information, obtaining the factory layout diagram.

[0056] Step S4142, confirming the operator's visual range area according to the factory layout diagram and the operator distribution diagram, and obtaining the operator's visual range area.

[0057] Due to the factory layout, machinery and equipment will block the operator's line of sight to a certain extent. Therefore, based on the factory layout and the layout of the operators, the area that the operator can see in the factory, that is, the operator's line of sight area, can be obtained.

[0058] Step S4143, obtaining the presentation position after the necessary information is transmitted, searching for an operator with a presentation position in the visual area and recording the operator as the first operator.

[0059] After the necessary information is transmitted, it will be presented on a display screen or other location for the operator to view. If the presentation location is within the field of view of operators of other devices, the operators of other devices may also see the necessary information.

[0060] Step S4144, obtaining the presentation area after the necessary information is transmitted, and setting the viewing distance threshold according to the presentation area.

[0061] Human vision is limited, and information cannot be read beyond a certain distance range. Therefore, based on the size of the presented area and the distance ratio checked on the eye chart, the farthest distance for viewing the necessary information is determined and set as the viewing distance threshold.

[0062] Step S4145, extracting the operation position of the first operator according to the operator distribution map, calculating the distance between the operation position and the presentation position and recording it as the actual distance.

[0063] Step S4146, find the first person whose actual distance is not greater than the viewing distance threshold and record him as the viewing person, and count the number of viewing people.

[0064] Step S4147: If the operator does not have the authority to view the required information, the number of viewers is 0.

[0065] Step S4148, forming a correlation curve between the number of viewers and the transmission security value based on the historical leakage data, and finding the transmission security value corresponding to the number of viewers based on the correlation curve and recording it as the second transmission security value.

[0066] A correlation curve is formed based on the frequency of data leakage and the number of viewers in the historical leakage data. The higher the frequency of data leakage, the lower the transmission security value. Therefore, a correlation curve is formed between the number of viewers and the transmission security value.

[0067] In actual use, data leakage is not only caused by basic transmission equipment such as transmission networks, but also by human data leakage. If the operator does not have the right to view the required information, the required information cannot be displayed, so the number of viewers is 0. If the operator has the right to view the required information, the required information will be displayed, and other operators may be able to view the required information. The number of operators who can see the required information is determined based on the operator's line of sight. The more operators there are, the greater the risk of data leakage.

[0068] Obtain the usage rate of the necessary information, and combine the transmission judgment results to confirm the steps of the controller from the adjustment equipment, the master control system and the operator, specifically: Step S51: If the transmission judgment result is that the data transmission channel between the associated device and the adjustment device is not opened, it is confirmed that the adjustment device has no control right.

[0069] If the data transmission channel between the associated device and the adjustment device is not opened, the adjustment device cannot autonomously generate a control plan through the device data of the associated device, so the adjustment device has no control.

[0070] Step S52, obtaining the ratio of the number of machines and equipment that use the necessary information to the total number of machines and equipment and recording it as the machine and equipment utilization rate.

[0071] For adjusting equipment, essential information is information that must be used, and this information may also be information that other equipment must use. Count the ratio of all equipment that use essential information to the total number of equipment in the factory.

[0072] Step S53, obtaining the ratio of the number of regulating devices using the necessary information to the total number of regulating devices and recording it as the regulating device utilization rate.

[0073] During the use of machinery and equipment in the factory, some machinery and equipment do not need parameter adjustment temporarily. The ratio of the number of equipment that needs to be adjusted and uses necessary information to the total number of adjusted equipment is counted.

[0074] Step S54, respectively set the usage weight ratios of the machine equipment usage rate and the adjustment equipment usage rate, and calculate the usage rate of the necessary information according to the machine equipment usage rate, the adjustment equipment usage rate and the corresponding usage weight ratios.

[0075] Step S55, obtaining the decision-making experience of the operator, and confirming the controller from the master control system and the operator.

[0076] Step S56: if the transmission determination result is to open the data transmission channel between the associated device and the adjustment device, then determine whether the usage rate reaches a preset usage rate threshold.

[0077] Step S57: If the preset usage rate threshold is not reached, confirm that the adjustment device is the controller.

[0078] Step S58: If the preset utilization rate threshold is reached, it is confirmed that the adjustment device has no control authority, and the controller is confirmed from the master control system and the operator.

[0079] In actual use, the automatic control of the equipment only controls the equipment itself according to the required information, without considering the operation of other equipment. Since the master control system can control all equipment, it can consider the operation of the equipment in the entire factory more comprehensively when making control decisions. If the usage rate of the necessary information is high and reaches the usage threshold, more machines and equipment can be adjusted in the master control system according to the information, or the operator can coordinate and control more equipment through the necessary information, which speeds up the subsequent equipment adjustment. If the usage rate of the necessary information is low, for example, only device B uses information A, and the data transmission channel is open, then it is obvious that information A is directly transmitted to device B, which can respond to equipment control more quickly. At this time, the adjustment device is directly controlled.

[0080] Obtain the decision-making experience of operators and confirm the steps of the controller from the master control system and operators, specifically: Step S551, determining whether the operator has the authority to view the necessary information. If the operator does not have the authority to view the necessary information, it is confirmed that the operator has no control authority and the master control system is the controller.

[0081] If the operator does not have the authority to view the necessary information, the operator cannot provide a control plan, so control can only be carried out by the master control system.

[0082] Step S552, if the operator has the authority to view the necessary information, the operator's operation accuracy is obtained, the average difference between the actual energy consumption after the operator's operation and the optimal energy consumption is counted, and the decision experience value is obtained according to the operation accuracy and the average difference.

[0083] Different operations will bring different energy consumption. The optimal solution will give the optimal energy consumption. The difference between the actual energy consumption after the operator's operation and the optimal energy consumption corresponding to this operation is counted, and the average difference of each operation is calculated to get the average difference. The weight ratio of the operation accuracy and the average difference is set respectively, and the decision experience value is calculated based on the operation accuracy, the average difference and the corresponding weight ratio.

[0084] Step S553, setting a decision experience value threshold, determining whether the operator's decision experience value reaches the decision experience value threshold, if not, confirming that the operator has no control authority, and the master control system is the controller.

[0085] Step S554: if reached, the cost of adjusting the equipment process is obtained, and the controller is confirmed based on the cost.

[0086] In actual use, the control of the master control system and the operator have their own advantages and disadvantages, and the operator needs to have a certain amount of experience to give accurate control. Therefore, when the operator's decision-making experience value does not reach the threshold, it will be more accurate for the master control system to control. When the operator's decision-making experience value reaches the threshold, the controller is confirmed based on the cost.

[0087] If it is reached, the cost of adjusting the equipment process is obtained, and the steps of the controller are confirmed according to the cost, which are as follows: Step S5541, obtaining the number of operation steps, average operation time and operation difficulty in the process of adjusting the device.

[0088] The parameter adjustment process of different adjustment devices has operation steps, and the operation difficulty is obtained according to the average operation accuracy of the operator. The higher the average accuracy, the lower the operation difficulty. At the same time, the average operation time of the operator is counted.

[0089] Step S5542, calculating the operation cost according to the number of operation steps, average operation time and operation difficulty.

[0090] The weight ratios of the number of operation steps, average operation time, and operation difficulty are set respectively, and the operation cost is calculated according to the number of operation steps, average operation time, operation difficulty, and the corresponding weight ratios.

[0091] Step S5543, obtaining historical adjustment data of the adjustment device, extracting historical adjustment data of the same type as the adjustment process of the adjustment device, and counting the average thinking time and calculation plan time of operators in the same type of historical adjustment data.

[0092] The adjustment of different devices involves different contents and different factors to be considered. Therefore, the length of time to think about the control scheme before control is also different. At the same time, some control schemes involve calculation content, and the calculation time is also different. The calculation scheme time refers to the calculation time of the calculation content in the scheme.

[0093] Step S5544, obtain the mental cost of the decision-making process based on the average thinking time and the calculation plan time, and add the operation cost to obtain the adjustment cost.

[0094] The weight ratios of the average thinking time and the solution calculation time are set respectively, and the mental cost is calculated according to the average thinking time, solution calculation time and the corresponding weight ratios.

[0095] Step S5545, setting an adjustment cost threshold. If the adjustment cost reaches the adjustment cost threshold, the master control system is confirmed as the controller.

[0096] Step S5546: If the adjustment cost does not reach the adjustment cost threshold, the operator is confirmed to be the controller.

[0097] In actual use, manual control can be more flexible according to the actual situation, which is more flexible than the control of the master control system. However, when the control requires high mental and operating costs, the operator will be burdened with heavy equipment control, so it is more convenient to control the equipment by the master control system.

[0098] A control system for smart factory affairs, by applying the control method for smart factory affairs as described above, comprises: The data storage module collects data from machines and equipment in the factory and records it as equipment data, and stores the equipment data.

[0099] The device adjustment module extracts parameter data from the device data, obtains the device that needs to be adjusted according to the parameter data and records it as the adjusted device.

[0100] The associated equipment module extracts the necessary information for adjusting the operation of the equipment from the equipment data, obtains the equipment corresponding to the necessary information and records it as the associated equipment.

[0101] The transmission judgment module obtains the sensitivity of the necessary information, judges whether to open the data transmission channel between the associated device and the adjustment device according to the sensitivity of the necessary information, and obtains the transmission judgment result.

[0102] The control confirmation module obtains the usage rate of the necessary information and confirms the controller from the adjustment equipment, the master control system and the operator in combination with the transmission judgment result.

[0103] The execution decision module obtains the corresponding decision given by the controller and uses it as the control decision, and the machine equipment executes the control decision.

[0104] The implementation principle of this system is as follows: first, the data of the machine equipment in the factory is collected and stored according to the data storage module, and recorded as equipment data at the same time. The parameter data in the equipment data is extracted by the adjustment equipment module, and the equipment to be adjusted is obtained according to the parameter data and recorded as the adjustment equipment. Then, the necessary information for the operation of the adjustment equipment is extracted from the equipment data through the associated equipment module, and the equipment corresponding to the necessary information is obtained and recorded as the associated equipment. The transmission judgment module obtains the sensitivity of the necessary information, and at the same time confirms the sensitivity threshold according to the security of the transmission channel. According to the sensitivity threshold, it is determined whether to open the data transmission channel between the associated equipment and the adjustment equipment, and obtains the transmission judgment result. The control confirmation module obtains the usage rate of the necessary information and confirms the controller from the adjustment equipment, the master control system and the operator in combination with the transmission judgment result. In the process of confirming the controller, it is necessary to consider whether the operation data transmission channel is open, whether the operator has the authority to view the necessary information, the usage rate of the necessary information, and the operating cost and mental cost that the operator needs to pay to control the equipment. Finally, the execution decision module obtains the corresponding decision given by the controller and uses it as the control decision, and the machine equipment executes the control decision.

[0105] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
