[0002] Intelligent plant is an innovative factory management solution, aiming to achieve comprehensive monitoring and optimization of factory equipment, production processes, and energy consumption by integrating a variety of advanced technologies and modules. There are various controls in intelligent plant, mainly the control of factory equipment. In the existing control of intelligent plant, after data analysis, the central control system usually realizes the control of factory equipment. However, in fact, a single control method will cause all data to be processed by the central control, increasing the burden on the central control system and bringing inconvenience to equipment control.

[0074] Figure 1 is a schematic diagram of the specific steps of an embodiment of a control method for intelligent factory services according to the present invention.

[0075] Figure 2 is a schematic diagram of the module connection of an embodiment of a control system for intelligent factory services according to the present invention. DETAILED DESCRIPTION OF THE INVENTION

[0076] The following will further elaborate on the present invention in conjunction with embodiments, but the implementation manners of the present invention are not limited thereto. Figure 1 - Figure 2

[0077] The present invention discloses a control method for intelligent factory operations, which specifically includes the following steps:

[0078] Step S1: Collect data of machine equipment in the factory and record it as equipment data, and store the equipment data.

[0079] Data generated during the operation of different machine equipment is uniformly stored in a memory.

[0080] Step S2: Extract parameter data from the equipment data, and obtain the equipment that needs to be adjusted based on the parameter data and record it as the adjustment equipment.

[0081] Step S3: Extract the necessary information for the operation of the adjustment equipment from the equipment data, and obtain the equipment corresponding to the necessary information and record it as the associated equipment.

[0082] Step S4: Obtain the sensitivity of the necessary information, and determine whether to open the data transmission channel between the associated equipment and the adjustment equipment based on the sensitivity of the necessary information, and obtain a transmission judgment result.

[0083] Step S5: Obtain the usage rate of the necessary information, and confirm the controller from the adjustment equipment, the total control system, and the operator in combination with the transmission judgment result.

[0084] Step S6: Obtain the corresponding decision given by the controller as the control decision, and the machine equipment executes the control decision.

[0085] The controller gives 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 by itself 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 obtain the product size according to the shaping size of the previous equipment and adjust the polishing parameters suitable for the product size. If the controller is the operator, it is executed according to the control decision manually operated by the operator. If the controller is the total control system, it is executed according to the control instruction execution plan sent by the total control system.

[0086] In actual operation, there are many machines and equipment in the factory, and the control methods of these devices are also diverse. The equipment can be self-controlled, or it can be controlled by a master control system, or it can be controlled manually. Different control methods have their own advantages and disadvantages. For the machines and equipment in the factory, using a single control method to control the machines and equipment is not conducive to the convenient operation of the equipment. Selecting different controllers and executing corresponding control decisions in different situations is beneficial to improving the accuracy of machine control and the efficiency of the operation of the machines and equipment. For example, when the equipment is automatically controlled, some data is required for judgment to give a control plan. However, due to the high sensitivity of some data, the equipment cannot call the required data, so the equipment cannot achieve automatic control at this time, and other control methods need to be selected to reduce the risk of data leakage.

[0087] The steps of extracting parameter data from the equipment data and obtaining the equipment to be adjusted based on the parameter data and recording it as the adjusted equipment are specifically as follows:

[0088] Step S21: Obtain the operation process of the factory facilities, and find the equipment corresponding to the operation process according to the operation process to form an equipment flow chart.

[0089] Step S22: Obtain the production requirements, and set the standard parameters of different equipment according to the production requirements and the equipment flow chart.

[0090] Step S23: Extract the real-time parameters of the equipment operation in the equipment data, compare the standard parameters with the real-time parameters of the corresponding equipment, and obtain the parameter difference value.

[0091] Step S24: Screen the equipment that needs to adjust the parameters according to the parameter difference value to form a set of adjusted equipment.

[0092] Set the threshold value of the parameter difference value according to the allowable error of different equipment. When the parameter difference value of the equipment reaches the threshold value of the parameter difference value, it is judged that the equipment needs to be adjusted.

[0093] Step S25: Set the adjustment priorities of different equipment, and select the equipment with the highest adjustment priority level in the adjustment priorities as the adjusted equipment.

[0094] Set the adjustment priorities of the equipment according to the impact degree of the equipment not being adjusted. The higher the impact degree of the equipment, the greater the adjustment priority.

[0095] In actual operation, there are many machines and equipment in the factory. Each machine and equipment has its own specific function, and these machines and equipment are interrelated. A minor change can have a major impact. Therefore, during the operation process, it is necessary to control and adjust the equipment. The operation of the equipment usually also has a standard process and can be adjusted according to production requirements to obtain the standard parameters that the equipment should be set. For example, in an ice cream stick manufacturing factory, the sizes of the ice cream sticks are different. During the packaging process, the sizes of the packaging bags produced are different. At the same time, the intervals for sealing the packages after packaging are different, and the time intervals for staying during the packaging process are also different. According to the changes in production requirements, the specific parameters that the equipment needs to be set can be obtained. If the real-time parameters are within the standard error range of the standard parameters, no adjustment is required. If not, the equipment needs to be adjusted. After adjusting the equipment with the highest priority, the equipment data is updated.

[0096] The step 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 is specifically as follows:

[0097] Step S31, obtain the reference information during the process of adjusting the parameters of the adjusting equipment. According to the judgment basis of whether the reference information is obtained through the equipment data, the types of reference information are divided into equipment reference data types and non-equipment reference data types.

[0098] Adjusting the equipment parameters is not a blind adjustment and requires certain data. For example, when the transmission speed of the ice cream sticks is 1 m / s, the packaging frequency of the packaging equipment is 1 time / s. When the transmission speed of the ice cream sticks is 2 m / s, the packaging frequency of the packaging equipment needs to be changed. Otherwise, the ice cream sticks cannot be accurately packaged. At this time, the reference information of the packaging equipment is the data of the transmission equipment of the ice cream sticks.

[0099] Step S32, extract the equipment data that conforms to the equipment reference data type from the equipment data and record it as the necessary information, and obtain the equipment corresponding to the necessary information and record it as the associated equipment.

[0100] In actual operation, the machines and equipment in the factory are interrelated. If there are deviations or adjustments in the operation of some equipment, it will cause parameter adjustments of other equipment. When adjusting the parameters of the adjusting equipment, it is also necessary to consider the operation parameters of other equipment to better achieve the coordinated operation of the factory's machines and equipment. And some data that is not obtained relying on other equipment is considered to be directly obtained and has no association with other equipment. The information associated with other equipment is recorded as the necessary information, which is beneficial to subsequent data transmission.

[0101] The step of obtaining the sensitivity of the necessary information, judging whether to open the data transmission channel between the associated equipment and the adjusting equipment according to the sensitivity of the necessary information, and obtaining the transmission judgment result is specifically as follows:

[0102] Step S41: Obtain the sensitivity of the essential information, obtain the transmission environment data, and determine the sensitivity threshold according to the transmission environment data.

[0103] The sensitivity of the essential information can be evaluated by the information entropy of the essential information or the availability of the essential information. Data with high information entropy usually contains more uncertainty and complexity, so it has higher sensitivity. The availability of data refers to the accessibility and integrity of the data. Data with high availability is usually easier to access and use, so it may have higher sensitivity.

[0104] Step S42: Determine whether the sensitivity of the essential information is greater than the sensitivity threshold. If it is greater than the sensitivity threshold, do not open the data transmission channel between the associated device and the adjustment device, and obtain the transmission judgment result.

[0105] Step S43: If it is not greater than the sensitivity threshold, determine whether the device data of the associated device and the adjustment device is compatible.

[0106] Step S44: If it is not compatible, do not open the data transmission channel between the associated device and the adjustment device, and obtain the transmission judgment result.

[0107] Step S45: If it is compatible, open the data transmission channel between the associated device and the adjustment device, and obtain the transmission judgment result.

[0108] In practical applications, in some controls such as distributed control, there are often situations of data islands, and data cannot be transmitted and shared between different devices. There are advantages and disadvantages to data sharing between devices. Not all cases of data islands bring negative effects. Obviously, when data is shared between devices to achieve automatic device control, 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 is determined according to the actual situation. If the sensitivity of the data is high, the transmission channel is not opened, and data cannot be shared between devices, reducing the negative consequences brought by data leakage. If the data sensitivity is not high, it is necessary to determine whether the data of the two devices is compatible. If it is not compatible, it will also increase the data processing burden on the device, and it is more likely that the device cannot process the received data. Therefore, not sharing data is beneficial to the operation of the factory facilities.

[0109] The steps of obtaining the sensitivity of the essential information, obtaining the transmission environment data, and determining the sensitivity threshold according to the transmission environment data are specifically as follows:

[0110] Step S411: Obtain the transmission environment data. The transmission environment data includes basic transmission environment data and personnel transmission environment data.

[0111] Step S412. The basic transmission environment data includes the leakage frequency of the essential information and the attack frequency of the data transmission channel.

[0112] Step S413. Obtain the first transmission security value based on the leakage frequency of the essential information and the attack frequency of the data transmission channel.

[0113] Respectively set the weight ratios of the leakage frequency and the attack frequency of the data transmission channel, and calculate the first transmission security value according to the leakage frequency, the attack frequency of the data transmission channel, and the corresponding weight ratios.

[0114] Step S414. The personnel transmission environment data includes the operator distribution map and the operator permissions. Obtain the second transmission security value according to the operator distribution map and the operator permissions.

[0115] Step S415. Superimpose the first transmission security value and the second transmission security value to obtain the transmission security value, and find the corresponding sensitivity threshold according to the preset transmission security value - sensitivity threshold table.

[0116] In practical applications, on the one hand, the leakage of data is related to the security settings of the data transmission channel. For example, whether the network is stable, whether there is a firewall, etc. The higher the leakage frequency, the less secure the transmission channel settings. The higher the attack frequency of the data transmission channel, the higher the risk of data being stolen. Therefore, the basic transmission risk is relatively high. 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 relatively secure, so high - sensitivity data can be transmitted. The lower the transmission security value, the lower the corresponding sensitivity. Since the risk of data leakage is relatively large, in order to reduce the negative consequences brought by data leakage, only some data with lower sensitivity can be transmitted.

[0117] The step of obtaining the second transmission security value according to the operator distribution map and the operator permissions is specifically as follows:

[0118] Step S4141. Judge whether the operator has the permission to view the essential information according to the operator permissions. If the operator has the permission to view the essential information, obtain the factory layout map.

[0119] Step S4142. According to the factory layout map and the operator distribution map, confirm the line - of - sight range area of the operator to obtain the line - of - sight area of the operator.

[0120] Due to the reason of the factory layout, the machinery and equipment will have a certain block on the operator's line of sight. Therefore, according to the factory layout and the layout of the operators, the area that the operator can see in the factory, that is, the line - of - sight area of the operator, can be obtained.

[0121] Step S4143: Obtain the presentation position after the transmission of the essential information, and find the operator within the line-of-sight area with the presentation position and record them as the first personnel.

[0122] After the essential information is transmitted, it will be presented at positions such as on the display screen for the operator to view. If the presentation position is within the line-of-sight area of the operator of other devices, the operator of other devices may also see the essential information.

[0123] Step S4144: Obtain the presentation area after the transmission of the essential information, and set the viewing distance threshold according to the presentation area.

[0124] Human vision is limited, and information cannot be read beyond a certain distance range. Therefore, according to the size of the presented area and the distance ratio checked by the visual acuity chart, determine the maximum distance to view the essential information and set it as the viewing distance threshold.

[0125] Step S4145: Extract the operation position of the first personnel according to the operator distribution map, calculate the distance between the operation position and the presentation position and record it as the actual distance.

[0126] Step S4146: Find the first personnel whose actual distance is not greater than the viewing distance threshold and record them as the viewing personnel, and count the number of viewing personnel.

[0127] Step S4147: If the operator does not have the permission to view the essential information, the number of viewing personnel is 0.

[0128] Step S4148: Form an association curve between the number of viewing personnel and the transmission security value according to the historical leakage data, and find the transmission security value corresponding to the number of viewing personnel according to the association curve and record it as the second transmission security value.

[0129] According to the historical leakage data, form an association curve between the data leakage frequency and the number of viewing personnel. Among them, the higher the data leakage frequency, the lower the transmission security value. Therefore, form an association curve between the number of viewing personnel and the transmission security value.

[0130] In actual application, the leakage of data is not only due to basic transmission equipment such as the transmission network, but also the situation of human data leakage. If the operator has no right to view the essential information, the essential information cannot be displayed, so the number of viewing personnel is 0. If the operator has the right to view the essential information, the essential information will be displayed, and at this time, the rest of the operators may all be able to view the essential information. According to the line of sight of the operator, confirm the number of operators who can see the essential information. The more the number of operators, the greater the risk of data leakage.

[0131] Steps to obtain the usage rate of the essential information and confirm the controller from the adjustment device, the total control system, and the operator in combination with the transmission judgment result are as follows:

[0132] Step S51, if the transmission judgment result is not to open the data transmission channel between the associated device and the adjustment device, it is confirmed that the adjustment device has no control right.

[0133] If the data transmission channel between the associated device and the adjustment device is not opened, the adjustment device cannot independently generate a control scheme through the device data of the associated device. Therefore, the adjustment device has no control right.

[0134] Step S52, obtain the ratio of the number of machine devices using the essential information to the total number of machine devices and record it as the machine device utilization rate.

[0135] For the adjustment device, the essential information is the information that must be used, and this information may also be the information that other machine devices must use. Statistically calculate the ratio of the number of machine devices using the essential information in the factory to the total number of machine devices.

[0136] Step S53, obtain the ratio of the number of adjustment devices using the essential information to the total number of adjustment devices and record it as the adjustment device utilization rate.

[0137] During the use of the machine devices in the factory, some machine devices do not need to be parameter-adjusted temporarily. Statistically calculate the ratio of the number of devices that need to be adjusted and use the essential information to the total number of adjustment devices.

[0138] Step S54, respectively set the weight ratios of the machine device utilization rate and the adjustment device utilization rate, and calculate the utilization rate of the essential information based on the machine device utilization rate, the adjustment device utilization rate, and the corresponding weight ratios.

[0139] Step S55, obtain the decision-making experience of the operator, and confirm the controller from the total control system and the operator.

[0140] Step S56, if the transmission judgment result is to open the data transmission channel between the associated device and the adjustment device, then judge whether the utilization rate reaches the preset utilization rate threshold.

[0141] Step S57, if it does not reach the preset utilization rate threshold, confirm that the adjustment device is the controller.

[0142] Step S58, if it reaches the preset utilization rate threshold, confirm that the adjustment device has no control right, and confirm the controller from the total control system and the operator.

[0143] In actual operation, the automatic control of the equipment only performs single control of the equipment itself based on the required information, without considering the operation of other equipment. Since the total 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 utilization rate of the essential information is relatively high and reaches the utilization rate threshold, more machine equipment can be adjusted in the total control system based on this information, or the operator can overall control more equipment through this essential information, which speeds up the subsequent equipment adjustment. If the utilization rate of the essential information is relatively low, for example, only equipment B uses information A and the data transmission channel is open, then obviously information A can be directly transmitted to equipment B for a faster response to equipment control, and at this time, it is directly controlled by the adjustment equipment.

[0144] To obtain the decision-making experience of the operator and confirm the controller from the total control system and the operator, the specific steps are as follows:

[0145] Step S551: Determine whether the operator has the permission to view the essential information. If the operator does not have the permission to view the essential information, it is confirmed that the operator has no control right, and the total control system is the controller.

[0146] If the operator has no right to view the essential information, the operator cannot give a control plan, so only the total control system can be used for control.

[0147] Step S552: If the operator has the permission to view the essential information, obtain the operation accuracy rate of the operator, count the average difference between the actual energy consumption and the optimal energy consumption after the operator's operation, and obtain the decision-making experience value based on the operation accuracy rate and the average difference.

[0148] Different operations will bring different energy consumptions. The optimal plan will give the optimal energy consumption. Count the difference between the actual energy consumption after the operator's operation and the optimal energy consumption corresponding to this operation, and calculate the average value of the differences for each operation to obtain the average difference. Set the weight ratios of the operation accuracy rate and the average difference respectively, and calculate the decision-making experience value based on the operation accuracy rate, the average difference, and the corresponding weight ratios.

[0149] Step S553: Set the decision-making experience value threshold, and determine whether the operator's decision-making experience value reaches the decision-making experience value threshold. If it does not reach, it is confirmed that the operator has no control right, and the total control system is the controller.

[0150] Step S554: If it reaches, obtain the cost consumed in the process of adjusting the equipment, and confirm the controller based on the cost.

[0151] In actual operation, the overall control system and the operator's control each have their own advantages and disadvantages. The operator needs to have a certain amount of experience to give accurate control. Therefore, when the decision-making experience value of the operator does not reach the threshold, it will be more accurate to be controlled by the overall control system. When the decision-making experience value of the operator reaches the threshold, the controller is confirmed according to the cost consumed.

[0152] If it reaches, the cost consumed in the process of adjusting the equipment is obtained. The steps of confirming the controller according to the cost are specifically as follows:

[0153] Step S5541: Obtain the number of operation steps, the average operation duration, and the operation difficulty in the adjustment process of the adjustment equipment.

[0154] There are operation steps in the parameter adjustment process of different adjustment equipment. The operation difficulty is obtained according to the average operation correct rate of the operator. The higher the average correct rate, the lower the operation difficulty. At the same time, the average operation duration of the operator is counted.

[0155] Step S5542: Calculate the operation cost according to the number of operation steps, the average operation duration, and the operation difficulty.

[0156] The weight ratios of the number of operation steps, the average operation duration, and the operation difficulty are set respectively, and the operation cost is calculated according to the number of operation steps, the average operation duration, the operation difficulty, and the corresponding weight ratios.

[0157] Step S5543: Obtain the historical adjustment data of the adjustment equipment, extract the historical adjustment data of the same type as the adjustment process of the adjustment equipment, and count the average thinking duration and the calculation plan duration of the operator in the historical adjustment data of the same type.

[0158] The adjustment of different equipment involves different contents and different factors to be considered, so the duration of thinking about the control plan before control is also different. At the same time, some control plans involve calculation content, and the calculation duration is also different. The calculation plan duration refers to the calculation duration of the calculation content in the plan.

[0159] Step S5544: Obtain the mental cost of the decision-making process according to the average thinking duration and the calculation plan duration, and superimpose the operation cost to obtain the adjustment cost.

[0160] The weight ratios of the average thinking duration and the calculation plan duration are set respectively, and the mental cost is calculated according to the average thinking duration, the calculation plan duration, and the corresponding weight ratios.

[0161] Step S5545: Set the adjustment cost threshold. If the adjustment cost reaches the adjustment cost threshold, confirm the overall control system as the controller.

[0162] Step S5546: If the adjustment cost does not reach the adjustment cost threshold, confirm that the operator is the controller.

[0163] In actual operation, manual control can be more flexibly changed according to the actual situation, which is more flexible than the control of the total control system. However, when the mental and operation costs required for control are relatively high, if the operator is still used to control the equipment at this time, it will impose a relatively heavy burden on the operator. Therefore, it is more convenient to control the equipment by the total control system at this time.

[0164] A control system for intelligent plant services, by applying a control method for intelligent plant services as described above, includes:

[0165] A data storage module, which collects the data of the machine equipment in the factory and records it as equipment data, and stores the equipment data.

[0166] An equipment adjustment module, which extracts the parameter data from the equipment data, and obtains the equipment to be adjusted according to the parameter data and records it as the adjustment equipment.

[0167] An associated equipment module, which extracts the necessary information for the operation of the adjustment equipment from the equipment data, and obtains the equipment corresponding to the necessary information and records it as the associated equipment.

[0168] A transmission judgment module, which obtains the sensitivity of the necessary information, judges whether to open the data transmission channel between the associated equipment and the adjustment equipment according to the sensitivity of the necessary information, and obtains the transmission judgment result.

[0169] A control confirmation module, which obtains the usage rate of the necessary information, and confirms the controller from the adjustment equipment, the total control system and the operator in combination with the transmission judgment result.

[0170] An execution decision module, which obtains the corresponding decision given by the controller as the control decision, and the machine equipment executes the control decision.

[0171] The implementation principle of this system is as follows: First, the data storage module collects and stores the data of the machine equipment in the factory, which is recorded as equipment data. The adjustment equipment module extracts the parameter data from the equipment data, and determines the equipment to be adjusted according to the parameter data, which is recorded as the adjustment equipment. Then, the associated equipment module extracts the necessary information for the operation of the adjustment equipment from the equipment data, and determines the equipment corresponding to the necessary information as the associated equipment. The transmission judgment module obtains the sensitivity of the necessary information, and at the same time determines the sensitivity threshold according to the security situation of the transmission channel, and judges whether to open the data transmission channel between the associated equipment and the adjustment equipment according to the sensitivity threshold, and obtains the transmission judgment result. The control confirmation module determines the controller from the adjustment equipment, the total control system and the operator by obtaining the usage rate of the necessary information and combining the transmission judgment result. During the process of determining the controller, it is necessary to consider whether the operation data transmission channel is open, whether the operator has the permission to view the necessary information, the usage rate of the necessary information, as well as the operation 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 as the control decision, and the machine equipment executes the control decision.

[0172] The above are all the preferred embodiments of this application, and the protection scope of this application is not limited by this. Therefore, all equivalent changes made according to the structure, shape and principle of this application should be covered within the protection scope of this application.
