Description

Technical Field

[0001] The present invention relates to a diagnosis method, in particular to a method for automatically diagnosing the aging of the performance of an antioxidant environment control box. Background Art

[0002] Currently, there are devices for storing precision electronic parts or other items that are easily oxidized or cannot come into contact with dust, such as Taiwan Patent No. M625005, "Structural assembly of a storage cabinet". It mainly has multiple cells on a storage cabinet, and the storage cabinet is provided with an automatic door opening device that can automatically open the door panels of each cell. Although it can prevent electronic parts from being oxidized or contacted with dust, it cannot be transported in large quantities due to its size, which increases logistics costs, increases the number of transportation vehicles, and also leads to the inability to reduce carbon emissions.

[0003] Therefore, how to eliminate the above-mentioned deficiencies is the technical difficulty that the present invention intends to solve. Summary of the invention

[0004] In view of the above problems, an object of the present invention is to provide a method for automatically diagnosing the aging of the performance of an antioxidant environment control box.

[0005] To achieve the above purpose, the present invention provides a method for automatically diagnosing the aging of the performance of an antioxidant environment control box, the steps of which include:

[0006] Installation step S1: In the installation step S1, a sensing group, a controller and an antioxidant device are installed in the box, the controller is electrically connected to the sensing group and the antioxidant device, and the controller is electrically connected to an external database, a computing module, a control panel, an alarm device and a remote device, and the database is electrically connected to the computing module.

[0007] Setting step S2: The setting step S2 sets the standard value, the predetermined value, the first default value and the second default value in the database installed in step S1.

[0008] Sensing step S3: The sensing step S3 uses the sensing group in the installation step S1 to sense the value of the environment inside the box.

[0009] Comparison step S4: In the comparison step S4, the value of the environment inside the box sensed in the sensing step S3 is transmitted to the controller, and then transmitted to the database by the controller. The database compares whether the value of the environment inside the box is greater than the standard value of the setting step S2. If the value of the environment inside the box in the comparison step S4 is less than the standard value of the setting step S2, jump back to the sensing step S3.

[0010] Anti-oxidation step S5: In the anti-oxidation step S5, when the value of the environment in the box is greater than the standard value in the setting step S2, the controller starts the anti-oxidation device and continues the sensing of the sensing step S3.

[0011] Calculation step S6: The calculation step S6 calculates the value sensed by the sensor in the sensing step S3 and the first default value and the second default value set in the database in the setting step S2 in the calculation module. If the result is aging, the diagnostic data is transmitted to the controller. If the result is a fault, the warning step S8 is performed.

[0012] Display step S7: In the display step S7, the controller transmits the sensing data in the sensing step S3 and the diagnostic data in the calculation step S6 to the control panel for display, so as to facilitate the user to judge the aging degree of the box and understand the condition of the environment inside the box.

[0013] Warning step S8: In the warning step S8, when the result of the calculation step S6 is a fault, the controller activates an alarm device or transmits a notification to a remote device.

[0014] The calculation step S6 is described in detail, and the calculation step S6 can be further divided into the following steps:

[0015] Opening the box step S61: The opening of the box step S61 is when the box needs to be opened to take out or place items, which will cause the environment inside the box to be affected by the external environment and cause the value of the environment inside the box to reach a peak.

[0016] Operation step S62: In the operation step S62, the value of the environment in the box is reduced from the peak value to the standard value through the sensing group and the anti-oxidation device in the sensing step S3 and the anti-oxidation step S5.

[0017] Aging diagnosis step S63: The aging diagnosis step S3 calculates the aging index of the box by changing the time taken for the value of the box environment in the box opening step S61 to rise to the peak and the time taken for the value to drop from the peak to the standard value in the operation step S62.

[0018] The first fault diagnosis step S64: The first fault diagnosis step is to determine a fault if the ratio between the time for the value of the environment in the box to rise to the peak and the time for it to drop from the peak to the standard value in the box opening step is greater than a first default value.

[0019] The second fault diagnosis step S65: The second fault diagnosis step S65 is that after the value of the environment inside the box in the box opening step S61 reaches the peak, it cannot drop to the standard value and there is a value beyond the peak. If the value beyond the peak minus the average value of the peak value is greater than the second default value, it is judged as a fault.

[0020] Among them, the formulas used to judge aging or failure include:

[0021] D=d×100…………(3) (Rhx-Rhe_avg)≥K3…………(6).

[0022] Furthermore, the values ​​of the environment inside the box are humidity, temperature and oxygen concentration.

[0023] Furthermore, the sensing group is a combination of a humidity sensor or a thermometer or an oxygen concentration sensor or a pressure sensor.

[0024] Furthermore, the anti-oxidation device is a combination of a moisture adsorption device, a temperature heater, or a non-oxygen gas ejection device.

[0025] Further, the warning device uses a siren or a warning light.

[0026] Furthermore, the remote device uses a mobile phone or a computer. Through the above steps, the items in the box can be prevented from being damaged by oxidation, and the aging degree of the box or whether the box is faulty can be known by opening and closing the box, and when the box is aged or faulty, it can be known in real time and handled.

DETAILED DESCRIPTION

[0037] In order to facilitate and briefly understand the other features and advantages of the present invention and the effects achieved by it, the present invention is now described in detail with reference to the accompanying drawings as follows:

[0038] Please refer to Figure 1 , Figure 2 As shown, a method for automatically diagnosing the aging of the performance of an antioxidant environment control box comprises the following steps:

[0039] Installation step S1: In the installation step S1, a sensing group 11, a controller 12 and an antioxidant device 13 are installed in the box 1. The controller 12 is electrically connected to the sensing group 11 and the antioxidant device 13, and the controller 12 is electrically connected to an external database 2, a computing module 3, a control panel 4, an alarm device 5 and a remote device 6, and the database 2 is electrically connected to the computing module 3.

[0040] Setting step S2: The setting step S2 sets the standard value Rhs, the predetermined value K1, the first default value K2 and the second default value K3 in the database 2 in the installation step S1, such as Figure 2 , Figure 6 shown.

[0041] Sensing step S3: The sensing step S3 uses the sensing group 11 in the installation step S1 to sense the value of the environment inside the box 1.

[0042] Comparison step S4: In the comparison step S4, the value of the environment inside the box 1 sensed in the sensing step S3 is transmitted to the controller 12, and then transmitted to the database 2 by the controller 12. In the database 2, it is compared whether the value of the environment inside the box 1 is greater than the standard value Rhs. If the value of the environment inside the box in the comparison step S4 is less than the standard value Rhs of the setting step S2, it jumps back to the sensing step S3.

[0043] Anti-oxidation step S5: In the anti-oxidation step S5, when the value of the environment in the box 1 is greater than the standard value Rhs in the setting step S2, the controller 12 starts the anti-oxidation device 13 and continues the sensing step S3. Figure 6 shown.

[0044] Calculation step S6: The calculation step S6 calculates the value sensed by the sensing group 11 in the sensing step S3 and the first default value K2 and the second default value K3 set in the database 2 in the setting step S2 in the calculation module 3. If the result is aging, the diagnostic data is transmitted to the controller 12. If the result is a fault, the warning step S8 is performed.

[0045] Display step S7: In the display step S7, the controller 12 transmits the sensing data in the sensing step S3 and the diagnostic data in the calculation step to a control panel 4 for display, so as to facilitate the user to judge the aging condition of the box 1 and understand the condition of the environment inside the box 1.

[0046] Warning step S8: In the warning step S8, when the result of the calculation step S6 is a fault, the controller 12 activates the alarm device 5 or transmits a notification to the remote device 6.

[0047] Please refer to Figure 3 , Figure 6 As shown, the calculation step S6 is described in detail, and the calculation step S6 can be further divided into the following steps:

[0048] Opening the box step S61: The opening box step S61 is when the box 1 needs to be opened to take or place items (such as Figure 4 , Figure 5 As shown), the environment inside the box 1 will be affected by the external environment, and the value of the environment inside the box 1 will reach a peak value e.

[0049] Operation step S62: In the operation step S62, the value of the environment in the box 1 is reduced from the peak value e to the standard value Rhs through the sensing group 11 and the anti-oxidation device 13 in the sensing step S3 and the anti-oxidation step S5.

[0050] Aging diagnosis step S63: The aging diagnosis step S63 calculates the aging index D of the box 1 by changing the time taken for the value of the environment in the box 1 to rise to the peak e in the box opening step S61 and the time taken for the peak e to drop to the standard value Rhs in the operation step S62.

[0051] The first fault diagnosis step S64: The first fault diagnosis step S64 is to determine a fault if the ratio between the time for the value of the environment in the box 1 to rise to the vertex e in the box opening step S61 and the time for the vertex e to drop to the standard value Rhs in the operation step S62 is greater than the first default value K2 set in the setting step S2.

[0052] Second fault diagnosis step S65: The second fault diagnosis step S65 is that after the value of the environment in the box 1 reaches the vertex e in the box opening step S61, it cannot drop to the standard value Rhs and there is a value beyond the vertex e (such as Fig. 9 If the value beyond vertex e minus the average value of vertex e is greater than the second default value K3, it is judged as a fault.

[0053] The values ​​of the environment in the box 1 are any factors that may easily cause the items in the box to oxidize, such as humidity, temperature, and oxygen concentration.

[0054] The sensing group 11 may be a combination of a humidity sensor, a thermometer, an oxygen concentration sensor, or a pressure sensor.

[0055] The anti-oxidation device 13 may be a combination of a moisture adsorption device, a temperature heater, or a non-oxygen gas ejection device.

[0056] The alarm device 5 may be a siren or a warning light.

[0057] The remote device 6 may be a mobile phone or a computer.

[0058] The formulas for determining aging or failure are as follows (for convenience, the sensing group 11 is a humidity sensor and the anti-oxidation device 13 is a moisture adsorption device as an example):

[0059] Please refer to Figure 6 , Figure 7 ,Should Figure 6 , Figure 7 The humidity change diagram is generated by opening and closing the box several times in the first cycle and the second cycle.

[0060] n represents the number of times the box is opened and closed during this period of time.

[0061] ta represents the time when the relative humidity Rh (Relative humidity) in the box 1 rises to the peak e.

[0062] tb represents the time it takes for the anti-oxidation device to reduce the humidity Rh in the box 1 to the standard value Rhs.

[0063] The standard value Rhs represents the humidity Rh value that should be reached in the preset box to ensure that the box 1 is dry enough to resist oxidation reaction.

[0064] The predetermined value K1 represents that the anti-oxidation device 13 stops operating when the humidity Rh in the box 1 reaches the predetermined value K1, and the anti-oxidation device 13 continues to operate when the humidity Rh in the box 1 returns to a value greater than or equal to the standard value Rhs.

[0065] Σ represents an operation symbol.

[0066] ERhs is the water adsorption efficiency, and its formula is:

[0067]

[0068] ERhs_P1 represents the moisture adsorption efficiency of the box after the cumulative opening and closing of n times during the first cycle, that is, Figure 6 The moisture adsorption efficiency.

[0069] ERhs_P2 represents the moisture adsorption efficiency of the box after the cumulative opening and closing of n times during the second cycle, which means Figure 7 The moisture adsorption efficiency.

[0070] The aging change rate d is the difference between ERhs_P1 and ERhs_P2, and its formula is:

[0071]

[0072] The aging index D is the aging change rate multiplied by 100, and its formula is:

[0073] D=d×100…………(3)

[0074] Among them, when the humidity Rh rises to the vertex e after the door is opened, it is defined as Rhe, and Rhe_avg represents the average value of the environment in the box 1 reaching the vertex e when the box 1 is opened and closed n times.

[0075]

[0076] The following is a practical example to calculate the aging index of cabinet 1:

[0077] The following is the data of the first cycle (the number of times the box 1 is switched is 3 times, n = 3)

[0078] Table 1

[0079]

[0080] The following is the data of the second cycle (the number of times the box 1 is switched is 3 times, n = 3)

[0081] Table 2

[0082]

[0083] Substituting the data in Table 1 into formula (1), we can know that ERhs_P1 is 91 / 4.7=19.36

[0084] Substituting the data in Table 2 into formula (1), we can know that ERhs_P2 is 125 / 6.2=20.16

[0085] Then, substituting ERhs_P1 and ERhs_P2 into formula (2), we can get the aging change rate d = (20.16-19.36) / 19.36 = 0.0413 = 4.13%

[0086] Substituting the aging change rate d into formula (3), we can get the aging index D = 4.13% × 100 = 4.13

[0087] The following will explain in detail how to identify a fault:

[0088] Please refer to Figure 8 , Figure 8 In the first fault judgment method, the user will set the first default value K2 in the database 2 in advance. The value of the first default value K2 is manually judged. For the convenience of the following formula description, K2 will be used as the label of the first default value K2.

[0089] The time when the anti-oxidation device cannot reduce the humidity Rh from the peak e to the standard value Rhs within a certain period of time is defined as tf.

[0090] When the ratio of tf to ta exceeds the first default value K2, it is determined to be a fault, and the controller will activate an alarm or send a notification to a remote device. The formula is as follows:

[0091]

[0092] Please refer to Fig. 9 , Fig. 9 For the second fault judgment method, the user will set the second default value K3 in the database first. The value of the second default value K3 is manually judged. For the convenience of the following formula description, the label K3 will be used as a representative of the second default value K3.

[0093] When the anti-oxidation device 13 cannot reduce the humidity Rh in the box from the peak e to the standard value Rhs within a certain period of time, or even exceeds the peak e, such as Fig. 9 At the position marked with X, the value of X is defined as Rhx. If Rhx minus the average value of vertex e (i.e., Rhe_avg) is greater than the second default value K3, it is determined to be a fault. The formula is as follows:

[0094] (Rhx-Rhe_avg)≥K3…………(6)

[0095] The following are actual examples. Fig. 9 Both fault conditions are included, so Fig. 9 For example:

[0096] Table 3

[0097] Rhs(%) K1(％) ta(min) tf(min) Rhe_avg(%) Rhx(%) 5 3 2 120 43 63

[0098] If the first default value K2 is 59, then by substituting ta and tf into formula (5), it can be known that (120 / 2)=60≥59 holds, and it is determined to be a fault.

[0099] If the second default value K3 is 20, then Rhe_avg and Rhx are substituted into formula (6), and it can be known that (63-43)=20≥20 holds, and it is determined to be a fault.

[0100] Through the above steps, the environment in the box 1 can meet the anti-oxidation standard, and the calculation step S6 executed by the calculation module 3 can calculate the aging index of the box 1 and determine whether the box 1 is faulty by opening and closing the box 1. If it is aged, the controller 12 can transmit the diagnostic data, that is, the sensed data, to the control board 4, so that the user can quickly know the condition of the environment in the box 1 through the control board 4. If it is faulty, the alarm device 5 is activated by the controller 12, or a notification is transmitted to the remote device 6, so that corresponding countermeasures can be quickly taken to prevent the items in the box 1 from being damaged by oxidation.

[0101] The above are only preferred embodiments of the present invention and are not intended to limit the patent scope of the present invention; therefore, any equivalent shape, structure or combination changes made without departing from the spirit and scope of the present invention should be included in the patent scope of the present invention.
