Description

Technical Field

[0001] The present invention relates to the technical field of tofu processing control, and specifically to an environmental control system adapted to a tofu processing production line. Background Art

[0002] Tofu is a traditional food mainly made from soybeans through processes such as soaking, grinding, boiling, coagulating, and forming. With the rise of healthy eating, tofu has become increasingly popular worldwide and has become an indispensable part of modern diet. Since the production process of tofu has relatively high requirements for environmental conditions, it is necessary to monitor and control the environment of the tofu processing production line; Currently, when controlling the environment where the tofu processing production line is located, it is often difficult to effectively monitor various environmental parameters and automatically adjust them reasonably, and it is impossible to accurately analyze and timely warn about the control performance of the tofu processing environment and the operating conditions of each adjustment device, which is not conducive to ensuring the suitability of the environment where the tofu processing production line is located and improving the quality of tofu, and significantly increases the supervision difficulty for management personnel; In view of the above technical defects, a solution is proposed now. Summary of the Invention

[0003] The purpose of the present invention is to provide an environmental control system adapted to a tofu processing production line, which solves the problems in the prior art that it is difficult to effectively monitor various environmental parameters and automatically adjust them reasonably, and it is impossible to accurately analyze and timely warn about the control performance of the tofu processing environment and the operating conditions of each adjustment device, which is not conducive to ensuring the suitability of the environment where the tofu processing production line is located and improving the quality of tofu, and the processing supervision is difficult.

[0004] To achieve the above purpose, the present invention provides the following technical solutions: An environmental control system adapted to a tofu processing production line includes an environmental parameter monitoring unit, a production line environmental suitability evaluation unit, an automatic control unit, an environmental adjustment device unit, a control backtracking feedback unit, and an intelligent terminal; the environmental parameter monitoring unit is integrated with several types of sensors, monitors the processing environment where the tofu processing production line is located based on various sensors, and sends the collected environmental parameter data to the production line environmental suitability evaluation unit and the intelligent terminal; The production line environmental suitability evaluation unit comprehensively evaluates the environmental suitability status of the processing environment where the tofu processing production line is located based on the environmental parameter data, and accordingly determines whether to generate a suitability abnormal signal. When generating a suitability abnormal signal, it sends it to the automatic control unit and the intelligent terminal; When the automated control unit receives a suitability anomaly signal, it generates a corresponding control strategy and automatically controls the environmental conditioning equipment unit based on the control strategy; the control backtracking feedback unit backtracks and evaluates the control status of the processing environment of the tofu processing production line, generates a backtracking pass signal or a backtracking alarm signal accordingly, and sends the backtracking pass signal or the backtracking alarm signal to the intelligent terminal. When the intelligent terminal receives the backtracking alarm signal, it issues a corresponding warning.

[0005] Furthermore, the specific analysis process of the production line environmental suitability evaluation unit includes: The temperature, humidity, and air velocity of the processing environment of the tofu processing production line are collected. The deviation value of the temperature compared to the corresponding standard temperature is marked as the tofu processing temperature measurement value. Similarly, the tofu processing humidity measurement value, the tofu processing air measurement value are obtained, and the pollution degree of the environment where the tofu processing production line is located is collected and marked as the tofu processing cleanliness measurement value; The tofu processing temperature measurement value, the tofu processing humidity measurement value, the tofu processing air measurement value, and the tofu processing cleanliness measurement value are respectively compared numerically with the preset tofu processing temperature measurement threshold, the preset tofu processing humidity measurement threshold, the preset tofu processing air measurement threshold, and the preset tofu processing cleanliness measurement threshold. If the tofu processing temperature measurement value, the tofu processing humidity measurement value, the tofu processing air measurement value, and the tofu processing cleanliness measurement value exceed the corresponding preset threshold, a suitability anomaly signal is generated.

[0006] Furthermore, if the tofu processing temperature measurement value, the tofu processing humidity measurement value, the tofu processing air measurement value, and the tofu processing cleanliness measurement value do not exceed the corresponding preset thresholds, the tofu processing temperature measurement value, the tofu processing humidity measurement value, the tofu processing air measurement value, and the tofu processing cleanliness measurement value are weighted and summed to calculate the tofu processing suitability anomaly value. The tofu processing suitability anomaly value is compared numerically with the preset tofu processing suitability anomaly threshold. If the tofu processing suitability anomaly value exceeds the preset tofu processing suitability anomaly threshold, a suitability anomaly signal is generated.

[0007] Furthermore, the adjustment equipment involved in the environmental conditioning equipment unit includes air conditioning units, humidifiers, dehumidifiers, air purifiers, and ventilation equipment.

[0008] Furthermore, the specific analysis process of the control backtracking feedback unit includes: When the automated control unit generates a corresponding control strategy, the corresponding moment is marked as the backtracking initial moment, and the moment when the environmental conditioning equipment unit completes the processing environment adjustment is marked as the backtracking end moment. The interval duration between the backtracking end moment and the backtracking initial moment is marked as the backtracking duration; All the backtracking durations in the detection period are obtained and their mean value is calculated to obtain the backtracking time table value. Also, the number of backtracking durations exceeding the preset backtracking duration threshold in the detection period is marked as the backtracking time abnormal value. The backtracking time table value and the backtracking time abnormal value are respectively compared numerically with the preset backtracking time table threshold and the preset backtracking time abnormal threshold. If the backtracking time table value or the backtracking time abnormal value exceeds the corresponding preset threshold, a backtracking alarm signal is generated.

[0009] Furthermore, if neither the backtracking time table value nor the backtracking time abnormal value exceeds the corresponding preset threshold, the number of generated times of the suitability abnormal signal in the detection period is marked as the suitability abnormal count value. By performing a weighted sum calculation on the suitability abnormal count value, the backtracking time table value, and the backtracking time abnormal value, the control and allocation detection coefficient is obtained. The control and allocation detection coefficient is compared numerically with the preset control and allocation detection coefficient threshold. If the control and allocation detection coefficient exceeds the preset control and allocation detection coefficient threshold, a backtracking alarm signal is generated; if the control and allocation detection coefficient does not exceed the preset control and allocation detection coefficient threshold, a backtracking qualified signal is generated.

[0010] Furthermore, control the backtracking feedback unit to communicate and connect with each equipment operation and inspection unit one by one, and control the backtracking feedback unit to send the backtracking qualified signal to each equipment operation and inspection unit one by one. When each equipment operation and inspection unit receives the backtracking qualified signal, it conducts a running evaluation on each regulating equipment involved in the environmental regulating equipment unit one by one, thereby identifying abnormal equipment and sending the abnormal equipment to the intelligent terminal. When the intelligent terminal receives the abnormal equipment, it issues a corresponding early warning.

[0011] Furthermore, the specific analysis process of each equipment operation and inspection unit is as follows: Obtain the operating parameters that need to be monitored during the operation of the corresponding regulating equipment. If the real-time detection data of the corresponding operating parameters does not meet the requirements of the corresponding standard data, it is determined that the corresponding operating parameters are in the optimization alarm state; obtain the total duration of the corresponding operating parameters in the optimization alarm state in the detection period and mark it as the optimization alarm time condition value, and respectively mark the maximum value and the average value of the deviation value of the real-time detection data of the corresponding operating parameters in the detection period compared with the corresponding preset standard data requirements as the period parameter deviation amplitude condition value and the period parameter deviation table condition value; By performing a weighted sum calculation on the optimization alarm time condition value, the period parameter deviation amplitude condition value, and the period parameter deviation table condition value, the period parameter obvious characteristic value is obtained. The period parameter obvious characteristic value is compared numerically with the corresponding preset period parameter obvious characteristic threshold. If the period parameter obvious characteristic value exceeds the corresponding preset period parameter obvious characteristic threshold, the corresponding operating parameter is marked as an abnormal detection parameter; if there are abnormal detection parameters in the corresponding regulating equipment during the detection period, the corresponding regulating equipment is marked as abnormal equipment.

[0012] Further, if there are no abnormal inspection parameters in the corresponding adjustment device during the detection period, a set of preset weight values is set in advance for each operating parameter. The ratio of the time period parameter display characteristic value of the corresponding operating parameter to the corresponding preset time period parameter display threshold value is calculated to obtain the time period parameter display occupancy value. The product result of the time period parameter display occupancy value and the corresponding preset weight value is marked as the time period parameter display status value; The sum of the time period parameter display status values of all operating parameters that need to be monitored by the corresponding adjustment device is calculated. Based on this, the adjustment device evaluation value is obtained. The adjustment device evaluation value is numerically compared with the corresponding preset adjustment device evaluation threshold value. If the adjustment device evaluation value exceeds the preset adjustment device evaluation threshold value, the corresponding adjustment device is marked as an abnormal device.

[0013] Further, the equipment one-by-one operation and inspection unit is communicatively connected to the tofu processing monitoring unit. If there are no abnormal devices during the detection period, the tofu processing monitoring unit evaluates the processing control status of the detection period based on the monitoring images of the processing environment where the tofu processing production line is located, so as to judge whether to generate a production control anomaly signal. When the production control anomaly signal is generated, it is sent to the intelligent terminal. When the intelligent terminal receives the production control anomaly signal, it issues a corresponding warning. The specific analysis process of the tofu processing monitoring unit is as follows: The image of the staff in the processing area where the tofu processing production line is located is obtained. The total duration during which there are no staff in the processing area during the detection period is marked as the personnel absence value. The personnel absence value is numerically compared with the preset personnel absence threshold value. If the personnel absence value exceeds the preset personnel absence threshold value, a production control anomaly signal is generated; If the personnel absence value does not exceed the preset personnel absence threshold value, all non-standard operation behaviors of the staff are identified based on the staff image. The occurrence times and the total duration of the non-standard operation behaviors during the detection period are marked as the non-standard operation detection frequency value and the non-standard operation detection time value. By performing a weighted sum calculation on the personnel absence value, the non-standard operation detection frequency value, and the non-standard operation detection time value, the tofu processing monitoring value is obtained. The tofu processing monitoring value is numerically compared with the preset tofu processing monitoring threshold value. If the tofu processing monitoring value exceeds the preset tofu processing monitoring threshold value, a production control anomaly signal is generated.

[0014] Compared with the prior art, the beneficial effects of the present invention are: 1. In the present invention, the production line environment suitability evaluation unit comprehensively evaluates the environment suitability status of the processing environment where the tofu processing production line is located based on various environmental parameter data. When a suitability anomaly signal is generated, the processing environment is adjusted by the automatic control unit, significantly reducing the difficulty of tofu processing supervision and improving the quality of the produced tofu. And by retrospectively evaluating the control status of the tofu processing environment and making reasonable improvement measures in a timely manner, it further ensures the suitability of the environment where the tofu processing production line is located and improves the tofu quality; 2. In the present invention, when the equipment-by-equipment inspection unit generates a qualified backtracking signal, it conducts a running evaluation on each adjustment device involved in the environmental adjustment device unit one by one to ensure the safe and stable operation of all adjustment devices. And when there is no abnormal device, the tofu processing monitoring unit evaluates the processing control status during the detection period based on the monitoring images of the processing environment where the tofu processing production line is located. When generating a production control difference signal, it strengthens the supervision and operation training of the on-site staff of the tofu processing production line, with high levels of intelligence and automation. BRIEF DESCRIPTION OF THE DRAWINGS

[0015] For the convenience of those skilled in the art to understand, the present invention will be further described below with reference to the accompanying drawings; Figure 1 It is a system block diagram of the first embodiment in the present invention; Figure 2 It is a system block diagram of the second and third embodiments in the present invention. DETAILED DESCRIPTION OF THE EMBODIMENTS

[0016] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0017] Embodiment 1: As Figure 1 shown, an environmental control system adapted to a tofu processing production line proposed by the present invention includes an environmental parameter monitoring unit, a production line environmental suitability evaluation unit, an automatic control unit, an environmental adjustment device unit, a control backtracking feedback unit, and an intelligent terminal; the environmental parameter monitoring unit is integrated with several types of sensors, monitors the processing environment where the tofu processing production line is located based on various sensors, and sends the collected environmental parameter data to the production line environmental suitability evaluation unit and the intelligent terminal, providing data support for the quality performance evaluation of the tofu processing environment and ensuring the accuracy of the analysis results; The production line environmental suitability evaluation unit comprehensively evaluates the environmental suitability status of the processing environment where the tofu processing production line is located based on the environmental parameter data, and accordingly determines whether to generate a suitability abnormal signal. When generating a suitability abnormal signal, it sends it to the automatic control unit and the intelligent terminal, so as to timely and reasonably adjust the tofu processing environment, ensure the suitability of the tofu processing environment, and reduce the adverse impact on the tofu quality; the specific analysis process of the production line environmental suitability evaluation unit is as follows: The temperature, humidity, and air velocity of the processing environment where the tofu processing production line is located are collected. The deviation value of the temperature from the corresponding standard temperature is marked as the tofu processing temperature measurement value. The deviation value of the humidity from the corresponding standard humidity is marked as the tofu processing humidity measurement value. The deviation value of the air velocity from the corresponding standard air velocity is marked as the tofu processing air measurement value. Additionally, the pollution degree of the environment where the tofu processing production line is located (i.e., the data volume value of the dust particle concentration) is collected and marked as the tofu processing cleanliness measurement value. Among them, the larger the value of the tofu processing cleanliness measurement value, the more serious the dust pollution of the processing environment. The tofu processing temperature measurement value, the tofu processing humidity measurement value, the tofu processing air measurement value, and the tofu processing cleanliness measurement value are respectively compared numerically with the preset tofu processing temperature measurement threshold, the preset tofu processing humidity measurement threshold, the preset tofu processing air measurement threshold, and the preset tofu processing cleanliness measurement threshold. If the tofu processing temperature measurement value, the tofu processing humidity measurement value, the tofu processing air measurement value, and the tofu processing cleanliness measurement value exceed the corresponding preset thresholds, it indicates that the overall environmental performance of the processing environment where the tofu processing production line is located is poor, and then a suitability anomaly signal is generated. If the tofu processing temperature measurement value, the tofu processing humidity measurement value, the tofu processing air measurement value, and the tofu processing cleanliness measurement value do not exceed the corresponding preset thresholds, then the tofu processing temperature measurement value, the tofu processing humidity measurement value, the tofu processing air measurement value, and the tofu processing cleanliness measurement value are weighted and summed to calculate the tofu processing suitability difference value. That is, corresponding preset weight coefficients are assigned to the tofu processing temperature measurement value, the tofu processing humidity measurement value, the tofu processing air measurement value, and the tofu processing cleanliness measurement value respectively. The tofu processing temperature measurement value, the tofu processing humidity measurement value, the tofu processing air measurement value, and the tofu processing cleanliness measurement value are respectively multiplied by the corresponding preset weight coefficients, and the sum value of the four groups of product results is marked as the tofu processing suitability difference value. Moreover, the larger the value of the tofu processing suitability difference value, the worse the overall environmental performance of the processing environment where the tofu processing production line is located. The tofu processing suitability difference value is compared numerically with the preset tofu processing suitability difference threshold. If the tofu processing suitability difference value exceeds the preset tofu processing suitability difference threshold, it indicates that the overall environmental performance of the processing environment where the tofu processing production line is located is poor and the processing environment needs to be adjusted accordingly, and then a suitability anomaly signal is generated.

[0018] When the automated control unit receives the suitability anomaly signal, it generates a corresponding control strategy and automatically controls the environmental regulation equipment unit based on the control strategy to maintain the suitability of the tofu processing environment. The automation level is high, significantly reducing the supervision difficulty of tofu processing. It should be noted that the adjustment equipment involved in the environmental regulation equipment unit mainly includes air conditioning units, humidifiers, dehumidifiers, air purifiers, and ventilation equipment, and the processing environment where the tofu processing production line is located is effectively regulated and controlled through each adjustment equipment.

[0019] The control backtracking feedback unit will backtrack and evaluate the control status of the processing environment of the tofu processing line, generate a backtracking qualified signal or a backtracking alarm signal accordingly, and send the backtracking qualified signal or the backtracking alarm signal to the intelligent terminal. When the intelligent terminal receives the backtracking alarm signal, it will issue a corresponding early warning to remind the management staff to conduct cause investigation and analysis and make reasonable improvement measures, so as to ensure the suitability of the environment where the tofu processing line is located and improve the quality of tofu. The specific analysis process of the control backtracking feedback unit is as follows: When the automation control unit generates the corresponding control strategy, it marks the corresponding moment as the backtracking initial moment, and marks the moment when the environmental adjustment equipment unit completes the adjustment of the processing environment as the backtracking end moment, and marks the time interval between the backtracking end moment and the backtracking initial moment as the backtracking duration. Among them, the larger the value of the backtracking duration, the slower the execution response efficiency of the corresponding control strategy; Obtain all the backtracking durations in the detection period and calculate their mean value to obtain the backtracking time table value, and mark the number of backtracking durations that exceed the preset backtracking duration threshold in the detection period as the backtracking time anomaly value. Compare the backtracking time table value and the backtracking time anomaly value with the preset backtracking time table threshold and the preset backtracking time anomaly threshold respectively. If the backtracking time table value or the backtracking time anomaly value exceeds the corresponding preset threshold, it indicates that the adjustment control performance of the detection period for the processing environment where the tofu processing line is located is poor, and a backtracking alarm signal is generated.

[0020] Furthermore, if both the backtracking time table value and the backtracking time anomaly value do not exceed the corresponding preset thresholds, mark the number of generated suitability anomaly signals in the detection period as the suitability anomaly count value, and calculate the control matching detection coefficient by weighted summation of the suitability anomaly count value, the backtracking time table value and the backtracking time anomaly value. That is, assign corresponding preset weight coefficients to the suitability anomaly count value, the backtracking time table value and the backtracking time anomaly value, multiply the suitability anomaly count value, the backtracking time table value and the backtracking time anomaly value by the corresponding preset weight coefficients respectively, and mark the sum value of the three product results as the control matching detection coefficient. And, the larger the value of the control matching detection coefficient, the worse the comprehensive adjustment control performance of the detection period for the processing environment where the tofu processing line is located; Compare the control matching detection coefficient with the preset control matching detection coefficient threshold. If the control matching detection coefficient exceeds the preset control matching detection coefficient threshold, it indicates that the comprehensive adjustment control performance of the detection period for the processing environment where the tofu processing line is located is poor, and a backtracking alarm signal is generated; if the control matching detection coefficient does not exceed the preset control matching detection coefficient threshold, it indicates that the comprehensive adjustment control performance of the detection period for the processing environment where the tofu processing line is located is good, and a backtracking qualified signal is generated.

[0021] Example 2: As Figure 2As shown in the figure, the difference between this embodiment and the first embodiment is that the control backtracking feedback unit is communicatively connected to the equipment-by-equipment inspection unit. The control backtracking feedback unit sends the backtracking qualified signal to the equipment-by-equipment inspection unit. When the equipment-by-equipment inspection unit receives the backtracking qualified signal, it conducts a running evaluation on each adjustment equipment involved in the environmental adjustment equipment unit one by one, and accordingly identifies abnormal equipment; And the abnormal equipment is sent to the intelligent terminal. When the intelligent terminal receives the abnormal equipment, it issues a corresponding warning to remind the management personnel to check and repair the corresponding adjustment equipment in time, ensuring the safe and stable operation of all adjustment equipment, which is conducive to improving the tofu processing efficiency and the quality of the produced tofu, and has a high level of intelligence. The specific analysis process of the equipment-by-equipment inspection unit is as follows: Obtain the operating parameters (such as temperature, voltage, current, etc.) that need to be monitored during the operation of the corresponding adjustment equipment, collect the real-time detection data of the corresponding operating parameters, and compare the real-time detection data with the corresponding standard data requirements. If the real-time detection data of the corresponding operating parameters does not meet the corresponding standard data requirements, it is determined that the corresponding operating parameters are in the optimized alarm state; Obtain the total duration during which the corresponding operating parameters are in the optimized alarm state during the detection period and mark it as the optimized alarm situation value, and mark the maximum value and the average value of the deviation of the real-time detection data of the corresponding operating parameters from the corresponding preset standard data requirements during the detection period as the period parameter deviation amplitude situation value and the period parameter deviation table situation value respectively; Calculate the period parameter display characteristic value by performing a weighted sum calculation on the optimized alarm situation value, the period parameter deviation amplitude situation value, and the period parameter deviation table situation value; that is, assign corresponding preset weight coefficients to the optimized alarm situation value, the period parameter deviation amplitude situation value, and the period parameter deviation table situation value respectively, multiply the optimized alarm situation value, the period parameter deviation amplitude situation value, and the period parameter deviation table situation value by the corresponding preset weight coefficients respectively, and mark the sum value of the three product results as the period parameter display characteristic value; and the larger the value of the period parameter display characteristic value, the worse the comprehensive parameter performance of the corresponding operating parameters during the detection period; Compare the period parameter display characteristic value with the corresponding preset period parameter display characteristic threshold. If the period parameter display characteristic value exceeds the corresponding preset period parameter display characteristic threshold, indicating that the comprehensive parameter performance of the corresponding operating parameters during the detection period is poor, then mark the corresponding operating parameters as abnormal inspection parameters; if there are abnormal inspection parameters in the corresponding adjustment equipment during the detection period, indicating that the operating performance of the corresponding adjustment equipment during the detection period is poor and the operating risk is high, then mark the corresponding adjustment equipment as abnormal equipment.

[0022] Furthermore, if there are no abnormal inspection parameters in the corresponding adjustment device during the detection period, a set of preset weight values greater than zero are preset for each operating parameter. Moreover, the more important the stable operation of the corresponding operating parameter is, the larger the value of the preset weight value matching it. Calculate the ratio of the time period parameter display characteristic value of the corresponding operating parameter to the corresponding preset time period parameter display characteristic threshold to obtain the time period parameter display occupancy value, and mark the product result of the time period parameter display occupancy value and the corresponding preset weight value as the time period parameter display status value. Sum up the time period parameter display status values of all operating parameters that need to be monitored by the corresponding adjustment device to obtain the adjustment device evaluation value. Compare the adjustment device evaluation value with the corresponding preset adjustment device evaluation threshold. If the adjustment device evaluation value exceeds the preset adjustment device evaluation threshold, it indicates that the operation performance of the corresponding adjustment device during the detection period is poor and the operation risk is high. Then, mark the corresponding adjustment device as an abnormal device.

[0023] Embodiment 3: As Figure 2 shown, the difference between this embodiment and Embodiment 1 and Embodiment 2 is that the equipment-by-equipment operation inspection unit is communicatively connected to the tofu processing monitoring unit. If there are no abnormal devices during the detection period, the tofu processing monitoring unit evaluates the processing control status of the detection period based on the monitoring images of the processing environment where the tofu processing production line is located, so as to determine whether to generate a production control difference signal. When generating a production control difference signal, send it to the intelligent terminal. When the intelligent terminal receives the production control difference signal, issue a corresponding warning to strengthen the supervision and operation training of the on-site staff of the tofu processing production line in a timely manner, and further ensure the smooth and stable progress of the subsequent processing process. Among them, the specific analysis process of the tofu processing monitoring unit is as follows: Obtain the images of the staff in the processing area where the tofu processing production line is located. Mark the total duration when there are no staff in the processing area during the detection period as the staff absence time value. Compare the staff absence time value with the preset staff absence time threshold. If the staff absence time value exceeds the preset staff absence time threshold, it indicates that it is difficult to effectively manage the tofu processing site during the detection period, and then generate a production control difference signal. If the staff absence time value does not exceed the preset staff absence time threshold, then identify all non-standard operation behaviors of the staff based on the staff images, and mark the occurrence times and the total duration of non-standard operation behaviors during the detection period as the non-standard operation detection frequency value and the non-standard operation detection time value. The tofu processing monitoring value is obtained by weighted summation of the personnel absence value, the operation non-standard frequency detection value, and the operation non-standard time detection value, that is, corresponding preset weight coefficients are assigned to the personnel absence value, the operation non-standard frequency detection value, and the operation non-standard time detection value, and the personnel absence value, the operation non-standard frequency detection value, and the operation non-standard time detection value are respectively multiplied by the corresponding preset weight coefficients, and the sum of the three sets of product results is marked as the tofu processing monitoring value; among them, the larger the value of the tofu processing monitoring value, the more abnormal the tofu processing monitoring status during the detection period. The tofu processing monitoring value is numerically compared with the preset tofu processing monitoring threshold. If the tofu processing monitoring value exceeds the preset tofu processing monitoring threshold, it indicates that the tofu processing monitoring status during the detection period is relatively abnormal, which is not conducive to ensuring the tofu processing efficiency and processing stability, and is not conducive to improving the quality of the processed tofu, then a production control difference signal is generated.

[0024] The working principle of the present invention: When in use, the environmental parameter monitoring unit monitors the processing environment where the tofu processing production line is located. The production line environmental suitability evaluation unit comprehensively evaluates the environmental suitability status of the processing environment where the tofu processing production line is located based on various environmental parameter data. When a suitability abnormality signal is generated, the automation control unit generates a corresponding control strategy, and based on the control strategy, the environmental regulation equipment unit is automatically controlled to maintain the suitability of the tofu processing environment, significantly reducing the difficulty of tofu processing supervision and improving the quality of the produced tofu. And through the control backtracking feedback unit, the control status of the processing environment where the tofu processing production line is located is backtracked and evaluated. When a backtracking alarm signal is generated, a cause investigation and analysis are carried out and reasonable improvement measures are taken to further ensure the suitability of the environment where the tofu processing production line is located and improve the tofu quality, with high intelligent and automation levels.
