Description

Technical Field

[0001] The present invention relates to the technical field of equipment control, and in particular to a dryer control system and method based on artificial intelligence. Background Art

[0002] With the acceleration of urbanization and the faster pace of people's lives, more and more people choose to send their clothes to dry cleaners for cleaning and drying. Therefore, the traditional way of drying clothes can no longer meet people's needs for quick drying of clothes. The emergence of dryers meets the needs of modern lifestyles for efficiency and convenience. It is an appliance used to convert wet clothes into dry clothes. It accelerates the drying process of clothes through hot air and mechanical movement.

[0003] At present, dry cleaners usually use a separate washing and drying method. The staff first takes the clothes with the washing label out of the washing machine and puts them into the dryer, and then sets the drying time according to experience. The air outlet in the dryer blows out hot air, and the inner drum rotates to evenly heat and dry the clothes. However, this method has certain disadvantages. For example: 1. Inexperienced staff setting different drying times often causes all clothes to be overheated or incompletely dried. 2. Each time multiple pieces of clothing are dried, a fixed drying time is used, which easily causes some clothes to be overheated while other clothes are too wet and fail to meet the drying requirements. 3. The clothing information in the washing machine and the clothing information in the dryer cannot be effectively linked and utilized, and the washing label can only be used as a certificate for manually distinguishing clothes from different customers, which is not intelligent enough. Therefore, at this stage, a more accurate, intelligent and efficient equipment control technology solution is needed to solve the above problems. Summary of the invention

[0004] The purpose of the present invention is to provide a dryer control system and method based on artificial intelligence to solve the problems raised in the above background technology.

[0005] In order to solve the above technical problems, the present invention provides the following technical solutions: a dryer control method based on artificial intelligence, the method comprising the following steps:

[0006] S100, collecting the wind speed comparison table of the dryer and the identifier and dry and wet weight of the clothes put in each time, and distinguishing different clothes through the electronic tags attached to each piece of clothing.

[0007] S200, calculating the total water weight and the total dry weight according to the difference between the dry and wet weights of the clothes in the dryer, thereby calculating the estimated drying time, and dividing the wind speed influence area according to the positions of each air outlet.

[0008] S300, during the rotation of the inner drum of the dryer, the water evaporation rate is calculated according to the local water weight and local dry weight of the clothes in each wind speed influence zone, and the wind speed of the air outlet of each wind speed influence zone is regulated by referring to the wind speed comparison table.

[0009] S400 collects the changes in drying time and total water weight in real time, and displays them in real time in digital form through the visual panel on the dryer.

[0010] In S100, the wind speed comparison table refers to a list of the relationship between the wind speed of each air outlet of the dryer and the water evaporation rate; the steps for collecting the identifier and dry and wet weight of the clothes are as follows:

[0011] S101, affix a waterproof electronic tag to each piece of clothing, put them into the washing machine for washing in turn, read the waterproof electronic tag on each piece of clothing by a tag reading device installed inside the washing machine to obtain an identifier, and use the pressure collected by the pressure sensor installed inside the washing machine as the dry weight of each piece of clothing.

[0012] S102, after washing, all the clothes are taken out and put into the dryer for drying. The waterproof electronic tag on each piece of clothing is read by the tag reading device installed inside the dryer to obtain the identifier, and the pressure collected by the pressure sensor installed inside the dryer is used as the wet weight of each piece of clothing.

[0013] The wind speed comparison table is obtained by the staff based on the actual measurements of the wind speed at each air outlet of the dryer and the water evaporation rate. Each minimum wind speed adjustment unit corresponds to a water evaporation rate range, and all water evaporation rates can find the corresponding wind speed in the wind speed comparison table.

[0014] There are multiple tag reading devices installed in the washing machine or dryer. The waterproof electronic tag adopts passive RFID technology. When the clothes are put into the washing machine or dryer, the multiple tag reading devices can not only associate the identifier stored in the waterproof electronic tag with the weight change information, but also analyze the intensity and phase difference of the return signal of the waterproof electronic tag to determine the real-time position of the waterproof electronic tag on the side wall of the inner drum.

[0015] In S200, the specific steps are as follows:

[0016] S201, the wet weight of each piece of clothing in the dryer is subtracted from the dry weight to obtain the water content weight, and the water content weights of all the clothing are summed to obtain the total water content weight , the total dry weight is obtained by summing up the dry weight of all clothes , substitute the total moisture weight and total dry weight into the formula to calculate the estimated drying time , the formula is as follows:

[0017]

[0018] In the formula, is the duration influence coefficient, is the dry weight influence coefficient, is the standard water evaporation rate.

[0019] The standard water evaporation rate is set in advance by the staff, and the specific value is based on the dryer capacity, hot air temperature and drying efficiency. The estimated drying time calculated by the standard water evaporation rate is not only a reference for users, but also an important basis for adjusting the wind speed.

[0020] S202, the dryer starts working and starts timing. The inner drum rotates to evenly distribute the clothes on the side wall of the inner drum. The pressure sensors evenly distributed below the side wall of the inner drum determine whether there are clothes on the upper part and collect the pressure. The tag reading device installed inside the dryer reads the real-time position of the clothes on the side wall of the inner drum.

[0021] S203, all the air outlets in the dryer are distributed at the bottom of the inner drum, and a cylindrical area is established as a wind speed influence area with the area where each air outlet is located as the bottom surface and the width of the inner drum side wall as the height, and each air outlet corresponds to a wind speed influence area.

[0022] The air outlet is a circular area with a certain area, and multiple circular areas surround the bottom boundary of the inner cylinder to form a hot air drying area. The wind direction of the air outlet takes the air outlet position as the starting point, and hot air drying is carried out along the width of the inner cylinder side wall. Therefore, the wind speed influence area corresponding to each air outlet is a cylindrical area, and each cylindrical area includes a piece of the inner cylinder side wall area.

[0023] In S300, the specific steps are as follows:

[0024] S301, analyzing the clothing information of each wind speed influence zone above the inner drum side wall area, summing up the dry weight of all the clothing belonging to the same wind speed influence zone to obtain the local dry weight, and obtaining the pressure collected by the pressure sensor below the inner drum side wall area of ​​the wind speed influence zone, substituting it into the centrifugal force formula to calculate the wet weight of these clothing and then subtracting the local dry weight to obtain the local water content weight.

[0025] During the operation of the dryer, the inner drum sidewall rotates continuously, but the air outlets do not rotate with the inner drum sidewall. The real-time position of the same piece of clothing on the inner drum sidewall may change multiple times in a short period of time, so the local dry weight of the clothing above the inner drum sidewall area in each wind speed influence area is also constantly changing. The local dry weight and local water weight at each moment are calculated in real time to adjust the corresponding air outlet wind speed.

[0026] S302: Subtract the timing time from the current time to obtain the drying time of the dryer , the local moisture weight, local dry weight and drying time of the clothes in each wind speed influence area are substituted into the formula to calculate the water evaporation rate, and the wind speed corresponding to the water evaporation rate is retrieved in the wind speed comparison table. The wind speed corresponding to the air outlet of each wind speed influence area is set according to the retrieval result. The formula is as follows:

[0027]

[0028] In the formula, is the water evaporation rate, is the local dry weight of the wind speed affected area, It is the local water content weight of the wind speed affected area.

[0029] The calculated water evaporation rate is usually a specific value. The interval of the water evaporation rate is retrieved in the wind speed comparison table, and the wind speed corresponding to the interval is found to set the corresponding outlet wind speed.

[0030] S303, the inner drum of the dryer keeps rotating, and the clothing information in each wind speed influence zone keeps changing. Repeat steps S301-S302 to adjust the air outlet wind speed of each wind speed influence zone in real time until the ratio of local water weight to local dry weight is less than the water weight ratio threshold. Then, the air outlet wind speed of the corresponding wind speed influence zone is reduced to zero. When the ratio of total water weight to total dry weight is less than the water weight ratio threshold, the dryer stops working and drying is completed.

[0031] When the ratio of the local water weight to the local dry weight of the clothes in an area on the side wall of the inner drum of the dryer is less than the water weight ratio threshold, it means that the clothes in this area have reached their purpose and do not need to be dried anymore. The wind speed of the air outlet that the area passes through during the rotation process is controlled to drop to zero, while the water evaporation rate of the clothes in other areas is still calculated in real time, and the wind speed of the air outlet that the clothes pass through is controlled to be adjusted in real time.

[0032] When the ratio of the total water weight to the total dry weight is less than the water weight ratio threshold, it means that all the clothes in the dryer have reached their destination and no longer need to be dried. The wind speed at all air outlets is controlled to drop to zero and the inner drum is stopped from rotating to complete the drying.

[0033] When the inner drum of the dryer rotates, the clothes rotate against the side walls of the inner drum due to centrifugal force, while the bottom of the inner drum does not rotate. The rapid change of wind speed at each air outlet ensures that the wind speed felt by the same piece of clothing during rotation is balanced.

[0034] The drying time includes the estimated drying time and the drying time. The changes in the estimated drying time, the drying time and the total moisture weight are displayed in real time in digital form through the visual panel on the dryer.

[0035] A dryer management and control system based on artificial intelligence, the system comprises a data acquisition module, an operation analysis module, an operation control module and a visualization module.

[0036] The data acquisition module is used to collect the dry and wet weight of the clothes, equipment information and wind speed comparison table. The operation analysis module calculates the total water weight through the dry and wet weight of the clothes, calculates the estimated drying time based on the total water weight and the total dry weight of all clothes, and analyzes the position of each air outlet in the equipment information to divide the wind speed influence area. The operation control module is used to calculate the local water weight and local dry weight of the clothes in each wind speed influence area, and calculates the water evaporation rate in real time based on the estimated drying time, and controls the outlet wind speed of each wind speed influence area with reference to the wind speed comparison table. The visualization module displays the changes in drying time and total water weight in real time through the dryer panel.

[0037] The data collection module includes a clothing information collection unit, a device information collection unit and a table information collection unit.

[0038] The clothing information collection unit is used to collect the identifier and dry and wet weight of each piece of clothing in the dryer. The equipment information collection unit is used to collect the position of each air outlet and the inner drum radius in the dryer, as well as the wind speed of each air outlet and the inner drum speed during operation. The table information collection unit is used to collect a list of the relationship between the wind speed of each air outlet and the water evaporation rate of this dryer.

[0039] The operation analysis module includes a duration analysis unit and an area division unit.

[0040] The duration analysis unit is used to calculate the estimated drying time for this drying; obtain the dry weight and wet weight of each piece of clothing in the dryer, and sum up the dry weight of all clothing to get the total dry weight , sum the wet weight of all clothes and subtract the total dry weight to get the total water content , substitute into the formula: Calculate the expected drying time ,in, is the duration influence coefficient, is the dry weight influence coefficient, is the standard water evaporation rate.

[0041] The area division unit is used to divide the wind speed influence area; the positions of each air outlet in the dryer are obtained, and a cylindrical area is established with the area where each air outlet is located as the bottom surface and the width of the inner drum side wall as the height as the wind speed influence area of ​​the corresponding air outlet.

[0042] The operation control module includes a wind speed adjustment unit and a rotation adjustment unit.

[0043] The wind speed adjustment unit is used to adjust the wind speed of each air outlet in the dryer.

[0044] First, when the dryer starts working, timing is started. The inner drum is rotated to make the clothes evenly distributed on the side wall of the inner drum. The pressure sensors evenly distributed below the side wall of the inner drum determine whether there are clothes on the top and collect the pressure. The label reading device installed inside the dryer reads the real-time position of the clothes on the side wall of the inner drum.

[0045] Secondly, the clothing information of each wind speed influence zone above the inner drum side wall area is analyzed, and the dry weight of all clothing belonging to the same wind speed influence zone is summed to obtain the local dry weight. , and obtain the pressure collected by the pressure sensor below the inner drum side wall area in the wind speed influence area, and substitute it into the centrifugal force formula together with the inner drum speed and inner drum radius to calculate the wet weight of these clothes and then subtract the local dry weight to obtain the local water weight .

[0046] Finally, the drying time of the dryer is calculated based on the time difference between the timing time and the current time. , substitute the local moisture weight, local dry weight and drying time of the clothes in each wind speed influence area into the formula: In the process, the water evaporation rate is calculated, and the wind speed corresponding to the water evaporation rate is retrieved in the wind speed comparison table. The wind speed of the air outlet corresponding to each wind speed influence area is set according to the retrieval result.

[0047] The rotation adjustment unit is used to control the rotation of the inner drum of the dryer. When the ratio of the local water content weight to the local dry weight is less than the water content weight ratio threshold, the wind speed at the air outlet of the corresponding wind speed influence area is reduced to zero, and the inner drum continues to rotate. When the ratio of the total water content weight to the total dry weight is less than the water content weight ratio threshold, the wind speed at all air outlets is reduced to zero, the inner drum stops rotating, and the drying ends.

[0048] The visualization module displays the changes in the estimated drying time, the drying time and the total moisture weight in real time in digital form through the dryer panel.

[0049] Compared with the prior art, the beneficial effects achieved by the present invention are:

[0050] 1. Intelligent drying time: This application collects the dry weight of clothes by the washing machine and the wet weight of clothes by the dryer, and calculates the total water weight of all clothes put in the dryer to predict the drying time.

[0051] 2. Efficient wind speed adjustment: This application adopts a multi-outlet asynchronous wind speed method to dynamically adjust the outlet wind speed according to the clothing information in the wind speed influence area above the inner drum side wall area. Compared with the traditional single outlet uniform wind speed design, the drying efficiency is higher and can meet the drying needs of different clothes.

[0052] In summary, compared with traditional technologies, the present invention has the advantages of intelligent drying time and efficient wind speed adjustment, and can improve drying efficiency. BRIEF DESCRIPTION OF THE DRAWINGS
