Description

Technical Field

[0001] The present invention relates to the field of oat production workshop management and control, and in particular to an exhaust monitoring system suitable for oat production and baking workshops. Background Art

[0002] Baked oatmeal is an instant cereal product made through a dry heat baking process. The oatmeal is processed using a low-temperature dehydration technology of 150-160℃ to make it hard and crispy and can be directly brewed and eaten without boiling. Compared with high-temperature processing technology, this method effectively retains dietary fiber components such as protein and β-glucan in oats, while also avoiding harmful substances that may be produced by high temperatures above 200℃. The product can be paired with milk, yogurt or eaten directly.

[0003] At present, food production workshops have gradually entered the field of intelligence and automation. Therefore, during oat production, the environmental control in the workshop is achieved with the help of automatic control systems such as industrial computers. However, since oat baking requires the use of low-temperature airflow baking equipment, it will generate large airflow disturbances in the workshop, causing dust and oat dust particles in the workshop to be rolled up, increasing the particle concentration in the air, easily contaminating oat products and increasing the wear of air filters in baking equipment. At the same time, since the moisture content of oat products needs to be kept extremely low during oat baking, the air humidity in the workshop is an important factor affecting the quality of oat products. Therefore, exhaust control and air purification control in oat baking workshops are particularly important.

[0004] For example, patent applications CN2019104633063 and CN202411679658X both involve air quality supervision and ventilation control in food workshops. However, the contents of the above two patents basically rely on real-time monitoring by sensors when controlling the exhaust and ventilation of the air in the workshop, and control the exhaust effect of the workshop through simple logic such as linear control or opening and closing control. This control method will result in insufficient fit between the exhaust power and the actual required power, which may easily cause product contamination due to insufficient exhaust power or energy waste due to excess exhaust power. For this reason, this application proposes a solution. Summary of the Invention

[0005] The present invention performs the first-level exhaust control through multiple air data in the oat workshop to ensure the basic operation of the oat baking workshop, and then performs a detailed quantitative analysis of the gas disturbance and the distribution probability of gas pollutants in the oat workshop to generate the purification demand efficiency. The second-level control of the exhaust equipment is performed based on the purification demand efficiency, so that the exhaust control can be more in line with the exhaust demand under actual conditions, reduce the power redundancy value of the exhaust system, and reduce the energy consumption of the exhaust system, so as to solve the problem that the exhaust control system of the workshop cannot meet the actual exhaust ventilation demand during oat baking, resulting in insufficient exhaust effect or excessive exhaust energy consumption. An exhaust monitoring system suitable for oat production and baking workshops is proposed.

[0006] The object of the present invention can be achieved by the following technical solution: an exhaust monitoring system suitable for an oat production and baking workshop, comprising an exhaust terminal control module for controlling the operating parameters of the exhaust equipment, a real-time monitoring module for the workshop air environment, an exhaust master control module, a fusion sub-control module and an operation auxiliary proofreading module;

[0007] The real-time monitoring module is used to monitor the air environment of the oat production workshop in real time, thereby obtaining the gas parameters in the workshop and sending the gas parameters to the exhaust master control module and the fusion sub-control module at the same time;

[0008] The operation auxiliary proofreading module continuously monitors the equipment in the oat production workshop, obtains the operating parameters of the production equipment, and sends the operating parameters of the production equipment to the fusion sub-control module;

[0009] After obtaining the gas parameters, the exhaust master control module performs standardized verification on the gas parameters, generates an exhaust control plan based on the standardized verification results, and sends the exhaust control plan to the exhaust terminal control module. The exhaust terminal control module controls the exhaust equipment according to the exhaust control plan;

[0010] After obtaining the operating parameters of the production equipment, the fusion sub-control module analyzes the operating parameters of the production equipment to obtain the air disturbance amount. The fusion sub-control module performs a mixed analysis of the gas parameters and the air disturbance amount to obtain the purification demand efficiency, and sends the purification demand efficiency to the exhaust master control module;

[0011] After obtaining the purification demand efficiency, the exhaust master control module corrects the exhaust control plan according to the purification demand efficiency to obtain an exhaust correction plan, and sends the exhaust correction plan to the exhaust terminal control module for execution.

[0012] As a preferred embodiment of the present invention, the air environment items detected by the real-time monitoring module include the content of inhalable particulate matter in the air, the content of harmful bacteria in the air, and the humidity at multiple points in the air, so as to obtain corresponding gas parameters according to the detected air environment items, namely, dust content, bacteria content and average humidity of the workshop;

[0013] When the real-time monitoring module calculates the average humidity of the workshop, it first obtains the preset humidity measurement point, and then calculates the distance Li between the humidity measurement point and the production equipment according to the preset production equipment position, where i is the number, i=1, 2, 3...n, n is the total number of humidity measurement points, and the reciprocal of the distance between the measurement point and the production equipment is calculated. As the weight for calculating the average humidity of the workshop, k is a set constant, and the value of k satisfies .

[0014] As a preferred embodiment of the present invention, when the operation auxiliary proofreading module monitors the equipment in the oat production workshop, the monitored categories include equipment type, operating time and operating power;

[0015] The operation auxiliary proofreading module obtains a preset operation coefficient according to the equipment type and creates an operation curve. The horizontal axis of the operation curve is the operation time and the vertical axis is the operation power. The operation curve is integrated to obtain the total operation workload. The operation auxiliary proofreading module multiplies the total operation workload and the operation coefficient to obtain the operation interference amount, and records the operation interference amount as the operation parameter of the production equipment.

[0016] As a preferred embodiment of the present invention, when the exhaust master control module performs standardized calibration on the gas parameters, it first obtains the gas standard range, specifically including the dust content range, the bacteria content range, and the humidity range, and compares the dust content in the gas parameters with the dust content range, the bacteria content with the bacteria content range, and the average humidity of the workshop with the humidity range. Based on the comparison results, it is confirmed whether the dust content, the bacteria content, and the average humidity of the workshop are within the set standard range;

[0017] The exhaust master control module generates a ventilation purification signal of a corresponding level when the dust content or bacteria content exceeds the corresponding standard range; generates a ventilation dehumidification signal of a corresponding level when the average humidity in the workshop exceeds the set standard range, and comprehensively records the ventilation purification signal or ventilation dehumidification signal as an exhaust control plan.

[0018] As a preferred embodiment of the present invention, the fusion sub-control module analyzes the operating parameters of the production equipment to obtain the operating interference amount, and performs a dispersion analysis on the operating interference amount based on the pre-input air volume in the workshop to obtain the air disturbance amount;

[0019] The fusion sub-control module then corrects the acquired gas parameters by the air disturbance amount to obtain gas correction parameters, and compares the gas correction parameters with the set standard range to obtain gas correction parameters that exceed the set standard range, and records the proportion of the gas correction parameters that exceeds the set standard range as the over-limit proportion. The over-limit proportion is analyzed by a formula to obtain the purification demand efficiency.

[0020] As a preferred embodiment of the present invention, the method for the fusion sub-control module to perform dispersion analysis on the motion interference amount is:

[0021] The fusion sub-control module divides the space in the workshop into multiple areas from near to far based on the distance from the midpoint to the production equipment, and obtains the air volume of each area respectively. The fusion sub-control module assigns corresponding thresholds to each area, where the sum of the thresholds is 1, and distributes the motion interference amount according to the corresponding thresholds. The motion interference amount is distributed to different areas, and then the ratio of the motion interference amount and the air volume of each area is calculated. Finally, the first m areas are selected as valid areas, and the ratios of the valid areas are arithmetic averaged to obtain the air disturbance amount.

[0022] As a preferred embodiment of the present invention, the method for the fusion sub-control module to obtain the gas correction parameters is:

[0023] The fusion sub-control module normalizes the air disturbance amount by a set coefficient so that the interval of the air disturbance amount is between [0, 1], and then calculates the air disturbance amount with the gas parameter to obtain the corrected gas parameter.

[0024] As a preferred embodiment of the present invention, after obtaining the purification demand efficiency, the exhaust master control module multiplies the existing exhaust control scheme by the purification demand efficiency to obtain a new exhaust control scheme, and operates according to the new exhaust control scheme.

Then, a detailed quantitative analysis of the gas disturbance and the distribution probability of gas pollutants in the oatmeal workshop is performed to generate a more detailed purification demand efficiency.

BRIEF DESCRIPTION OF THE DRAWINGS

[0028] To facilitate understanding by those skilled in the art, the present invention is further described below with reference to the accompanying drawings.

[0029] Figure 1 is a system block diagram of the present invention;

[0030] Figure 2 It is a system flow chart of the present invention. DETAILED DESCRIPTION

[0031] The following is a clear and complete description of the technical solutions of the present invention in conjunction with the embodiments. Obviously, the embodiments described are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0032] Example 1: Please refer to Figure 1 - Figure 2 As shown, the exhaust monitoring system suitable for oatmeal production and baking workshops includes an exhaust terminal control module for controlling the operating parameters of the exhaust equipment, a real-time monitoring module for the workshop air environment, an exhaust master control module, a fusion sub-control module, and an operation auxiliary proofreading module;

[0033] The real-time monitoring module is used to monitor the air environment of the oat production workshop in real time. The air environment items detected by the real-time monitoring module include the content of inhalable particulate matter in the air, the content of harmful bacteria in the air, and the humidity at multiple points in the air, so as to obtain the gas parameters in the workshop. The gas parameters include gas parameters, namely dust content, bacterial content and average humidity of the workshop, and the gas parameters are sent to the exhaust master control module and the fusion sub-control module at the same time;

[0034] When the real-time monitoring module calculates the average humidity of the workshop, it first obtains the preset humidity measurement point, and then calculates the distance Li between the humidity measurement point and the production equipment according to the preset production equipment position, where i is the number, i=1, 2, 3...n, n is the total number of humidity measurement points, and the reciprocal of the distance between the measurement point and the production equipment is calculated. As the weight for calculating the average humidity of the workshop, k is a set constant, and the value of k satisfies , and then the weighted average is performed through the corresponding weights to obtain the average humidity of the workshop;

[0035] After obtaining the gas parameters, the exhaust master control module performs a standardized calibration on the gas parameters and generates an exhaust control plan based on the standardized calibration results. When performing the standardized calibration on the gas parameters, the exhaust master control module first obtains the gas standard range, specifically including the dust content range, bacterial content range, and humidity range, and compares the dust content in the gas parameters with the dust content range, the bacterial content with the bacterial content range, and the average humidity of the workshop with the humidity range. Based on the comparison results, it is confirmed whether the dust content, bacterial content, and average humidity of the workshop are within the set standard range;

[0036] When the dust content or bacteria content exceeds the corresponding standard range, the exhaust control module generates a ventilation purification signal of the corresponding level. When the average humidity of the workshop exceeds the set standard range, it generates a ventilation dehumidification signal of the corresponding level. The ventilation purification signal or ventilation dehumidification signal is comprehensively recorded as an exhaust control plan.

[0037] Specifically, the level of the generated ventilation purification signal is determined as follows: the dust content or bacteria content exceeding the standard range is recorded as the over-limit amount, and the over-limit ratio CB is calculated by calculating the ratio of the over-limit amount to the maximum value in the standard range. The operating power Ps of the ventilation and purification equipment is obtained, where P is the normal continuous operating power of the ventilation and purification equipment. The exhaust master control module compares the operating power Ps with the set operating power gears P1, P2, etc., determines the gear to which Ps belongs, and rounds up to determine the corresponding ventilation and purification signal level;

[0038] Similarly, the ventilation and dehumidification signal level is obtained in the same way;

[0039] Finally, the exhaust master control module sends the exhaust control plan to the exhaust terminal control module, and the exhaust terminal control module controls the exhaust equipment according to the exhaust control plan.

[0040] Example 2: Please refer to Figure 1 - Figure 2 As shown, the operation auxiliary proofreading module continuously monitors the equipment in the oat production workshop, obtains the operating parameters of the production equipment, and sends the operating parameters of the production equipment to the fusion sub-control module. The categories monitored by the operation auxiliary proofreading module include equipment type, operating time and operating power;

[0041] The operation auxiliary calibration module obtains the preset operation coefficient according to the equipment type and creates an operation curve. The horizontal axis of the operation curve is the operation time, and the vertical axis is the operation power. The total operation workload is obtained by integrating the area formed by the operation curve and the horizontal axis. The operation auxiliary calibration module calculates the product of the total operation workload and the operation coefficient to obtain the operation interference amount, and records the operation interference amount as the operation parameter of the production equipment.

[0042] After obtaining the operating parameters of the production equipment, the fusion sub-control module analyzes the operating parameters of the production equipment to obtain the operating interference amount. It then performs a dispersion analysis of the operating interference amount based on the pre-input air volume in the workshop. The space in the workshop is divided into multiple areas from near to far based on the distance from the production equipment as the midpoint. The air volume of each area is obtained separately. The fusion sub-control module assigns corresponding thresholds to each area, where the sum of the thresholds is 1. The motion interference amount is distributed according to the corresponding thresholds and allocated to different areas.

[0043] Then, the ratio of the motion disturbance and the air volume of each area is calculated, and finally the first m areas are selected as the effective areas. The arithmetic average of the ratios of the effective areas is taken to obtain the air disturbance. The fusion sub-control module performs a mixed analysis of the gas parameters and the air disturbance, corrects the obtained gas parameters by the air disturbance, and normalizes the air disturbance by the set coefficient so that the interval of the air disturbance is between [0,1].

[0044] Then calculate the gas parameters with the formula to get the corrected gas parameters F (x), , where F(x) is the gas correction parameter, f(x) is the gas parameter, R is the air disturbance amount, and the gas correction parameter is compared with the set standard range to obtain the gas correction parameter that exceeds the set standard range, and the ratio of the gas correction parameter exceeding the set standard range is recorded as the over-limit ratio, through the formula Analyze the excess ratio to obtain the purification demand efficiency, where η is the purification demand efficiency and q is the excess ratio, and send the purification demand efficiency to the exhaust master control module;

[0045] After obtaining the purification demand efficiency, the exhaust master control module modifies the exhaust control plan by multiplying the existing exhaust control plan by the purification demand efficiency to obtain a modified exhaust plan, and sends the modified exhaust plan to the exhaust terminal control module for execution;

[0046] Among them, when confirming the exhaust correction plan, the purification demand efficiency is multiplied by the operating power Ps, and the result of the product is compared with the set operating power levels P1 and P2, and rounded up to obtain a new ventilation purification signal level, thereby generating an exhaust correction plan.

[0047] The preferred embodiments of the present invention disclosed above are intended only to help illustrate the present invention. These preferred embodiments do not exhaustively describe all details, nor do they limit the present invention to specific embodiments. Obviously, many modifications and variations are possible based on the contents of this specification. These embodiments are selected and described in detail in this specification to better explain the principles and practical applications of the present invention, thereby enabling those skilled in the art to better understand and utilize the present invention. The present invention is limited only by the claims and their full scope and equivalents.
