Description

Technical Field

[0001] The invention belongs to the technical field of air environment control and processing, and in particular relates to an environmental control system for more effectively regulating the humidity of an archive storehouse. Background Art

[0002] The archive warehouse is used to store archives. It arranges compact shelving to safely preserve the archives. The purpose of this is to: improve the security of archive preservation to a certain extent, and because the archives are locked in the password cabinet of the compact shelving, it can reduce the contact with the external environment and reduce the probability of archives getting damp and moldy during long-term storage.

[0003] However, since the storage of archives is a long-term work, it is necessary to add and retrieve archives during the process, which causes the air in the archives warehouse to mix into the password cabinet, increasing the possibility of long-term storage of archives getting damp and moldy. Therefore, it is necessary to regularly improve the air environment in the archives warehouse. The improvement points are usually: adjust the temperature in the warehouse and reduce the moisture and mold content in the air.

[0004] To adjust the temperature in the warehouse and reduce the moisture in the air, large central air conditioners are usually used with intelligent temperature sensor control units in each area of ​​the archive warehouse for temperature control. When air dehumidification is required, large central air conditioners are used with dehumidifiers in each area for dehumidification. Sterilization lamps are usually mounted on the walls of the archive warehouse to eliminate mold in the air environment.

[0005] This method of directly using the hot and cold exchange method in the air-conditioning system for dehumidification and sterilizing with a stable sterilization lamp is generally ineffective during the rainy season and the fungus breeding season, especially for large archive warehouses. The main reasons are: the hot and cold exchange method cannot effectively reduce air humidity, and the space is large; secondly, the sterilization lamp requires long-term exposure to have a better sterilization effect. In addition, even with the support of the air-conditioning system in large warehouses, the flow speed is generally not good, and the air in the dense shelving area cannot be sterilized well.

[0006] The invention patent with the authorization announcement number: CN102323839B discloses a system for temperature, humidity and environmental control of archive warehouses, which involves a medium-humidity sub-warehouse control system, which includes a humidity control device and a temperature detection device. The humidity control device and the temperature detection device work together to control the temperature in the medium-humidity sub-warehouse at 22°C-25°C, and the humidity is controlled between 65%-70%; a low-humidity sub-warehouse control system, which includes a humidity control device and a temperature detection device, and the humidity control device and the temperature detection device work together to control the temperature in the medium-humidity sub-warehouse at 18°C-21°C, and the humidity is controlled between 50%-55%; an exhaust system, whose exhaust port is arranged in the medium-humidity sub-warehouse and the low-humidity sub-warehouse, and is used to exhaust the medium-humidity sub-warehouse and the low-humidity sub-warehouse; an exhaust control device, which is connected to the exhaust system and can The exhaust operation of the medium-humidity sub-warehouse and the low-humidity sub-warehouse are controlled separately; a plurality of negative ion air purifiers are respectively arranged in the medium-humidity sub-warehouse and the low-humidity sub-warehouse, for generating negative ions for purifying the air in the medium-humidity sub-warehouse and the low-humidity sub-warehouse; a plurality of monitors are respectively arranged in the medium-humidity sub-warehouse and the low-humidity sub-warehouse, for monitoring the storage quantity of goods in each warehouse; a control center system, when the monitor in the medium-humidity sub-warehouse detects that the inventory in the medium-humidity sub-warehouse is sharply reduced, the control center system starts the temperature and humidity transfer system between the medium-humidity sub-warehouse and the low-humidity sub-warehouse, so as to realize the temperature and humidity exchange between the medium-humidity sub-warehouse and the low-humidity sub-warehouse.

[0007] It can be seen that the temperature and humidity of the warehouse can be adjusted by exchanging air in warehouses with different air temperature and humidity conditions. However, in this case, although a certain temperature and humidity adjustment effect can be achieved, the dehumidification effect is not obvious, especially when it is put into use in large archive warehouses. Due to the large area of ​​large warehouses, even under the current exhaust control device adjustment, the humidity exchange speed is slow, and the air in different space areas is neutralized, and the dehumidification speed is slow.

[0008] The invention patent with authorization announcement number: CN117148901B discloses a warehouse environment control system based on the Internet of Things, involving an environment control terminal setting module, which is used to record the archive warehouse to be environmentally controlled as the target warehouse and obtain the length of the target warehouse, and then set the environment control terminals at equal intervals on the ceiling of the target warehouse based on this, wherein the environment control terminals are connected to the environment control equipment, and at the same time, a sliding track is set on the ceiling of the target warehouse according to the length of the warehouse, and an ultraviolet sterilization lamp is set on the track, and the ultraviolet sterilization lamp can move on the sliding track.

[0009] It can be seen that it can sterilize different areas of the compact shelving by inductive fixed-point irradiation with ultraviolet lamps that can move along the track. However, just like the above method, sterilization is carried out using sterilization lamps. Although this method can be more flexible to sterilize areas with a large amount of mold, it takes a long time to sterilize. In addition, the air in the warehouse is fluid. If there are multiple places that need to be sterilized at the same time, in order to achieve a certain sterilization effect, the action reaction time is long.

[0010] At present, the better way to sterilize and dehumidify the air is usually to use an air filter membrane to filter out the mold and use a desiccant to absorb the moisture in the air, which can dehumidify and reduce bacteria in the air more effectively. The invention patent with the authorization announcement number: CN112807889B discloses an air filter and a photoelectric device, a filter frame, a partition bracket, and a filter layer for filtering particulate matter, a first adsorption layer for adsorbing mold, salt ions and acidic ions, and a second adsorption layer for adsorbing moisture, which are arranged in sequence and spaced relative to each other in the filter frame.

[0011] Its advantage in dehumidification and bacteria reduction is that after the air is sucked into the filter membrane and the desiccant, the mold is effectively intercepted in the air filter membrane, and the moisture can be effectively absorbed by the desiccant. After repeated operations, the presence of mold and moisture in the air can be greatly reduced.

[0012] However, this type of plate filtration setting is more suitable for air dehumidification and sterilization operations in a small space. When it is put into use in a large warehouse, in order to achieve a better air sterilization content and moisture control level in the compact shelving placement area, due to the large installation volume of the compact shelving, the usage is large. During the use of this type of filter, the impurity removal layer is used for a longer time, while the adsorption layer for filtering mold and adsorbing water is scrapped faster than the impurity removal layer. The main reason is that the archive warehouse is relatively clean due to long-term cleaning, and the adsorption layer for filtering mold and adsorbing water will reduce the air circulation efficiency to a certain extent after absorbing water and filtering bacteria. Under long-term treatment, the air circulation resistance of the adsorption layer increases, and it is not suitable to continue to use it at this time and needs to be replaced. However, this layer-type filling process is not conducive to the actual operation and replacement of management personnel during actual operation.

[0013] To this end, it is necessary to set up a central air-conditioning system for use with the archive warehouse, which can more effectively sterilize and remove moisture from the air environment in the compact shelving area, and facilitate the replacement of the filter area for filtering mold and adsorbing water to meet actual needs. Summary of the invention

[0014] The purpose of the present invention is to provide an environmental control system for an archive warehouse, and the technical problem to be solved is to provide an environmental control system that can more effectively control the air humidity environment of the archive warehouse.

[0015] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: an archive warehouse environmental control system, comprising a processing box and a support box arranged on one side of the processing box, wherein suction pipes are evenly arranged at the front and rear of the top of the support box, a connecting hose is connected to the top of the suction pipe, a solenoid valve is connected to the lower end of the suction pipe, and a primary filter mechanism is connected to the exhaust end of the solenoid valve, and the primary filter mechanism is used to filter impurities and dust from the air in the dense shelf area; A suction pump 1 is arranged on one side of the processing box, and the suction end of the suction pump 1 is connected to a primary filtering mechanism through a suction pipe 2, and an air volume sensor 1 is installed on the suction pipe 2, and the suction end of the suction pump 1 is connected to a suction pipe 2, and the exhaust end of the suction pump 1 is connected to a discharge joint 1, and one end of the discharge joint 1 is connected to an access hose, and a changing mechanism is arranged on the other side of the processing box, and at least two rear filter mechanisms are installed in the changing mechanism, and a side frame box is arranged on the processing box and the changing structure, and a suction pump 2 is arranged on the lower side of the side frame box, and the suction end of the suction pump 2 is connected to a discharge joint 2 and the discharge joint 2 is connected to an access hose, and the changing mechanism is used to replace the rear filter mechanism between the access hose and the access hose, and the rear filter mechanism is used to remove mold and moisture from the exhaust air inside in real time; The exhaust end of the second vacuum pump is connected to a discharge pipe, a support baffle is provided at one end of the side frame box, an air collecting strip is provided on the support baffle, one end of the discharge pipe is connected to the air collecting strip, one side of the air collecting strip is evenly connected to the front and back with a discharge pipe, one end of the discharge pipe is connected to the second electromagnetic valve, the discharge end of the second electromagnetic valve is connected to the discharge pipe and the discharge pipe is connected to the second connecting hose; The archive warehouse environmental control system also includes a humidity sensor arranged on the top of the archive compact rack, an air suction pipe and an air exhaust pipe arranged on the ceiling of the warehouse, and a mold VOC sensor arranged on both sides of each archive compact rack; The air suction pipe is connected to the first connecting hose, and the air exhaust pipe is connected to the second connecting hose; A control mechanism is provided on the upper part of one side of the processing box, and the control mechanism is used to control the operation of vacuum pump 1 and vacuum pump 2 according to the humidity conditions uploaded by the humidity sensor and the mold content conditions uploaded in real time by the mold VOC sensor, so that the air in the archive shelving area is purified and dried during the process of passing through the primary filter mechanism and the post-filter mechanism; the control mechanism is also used to determine and analyze whether the primary filter mechanism needs to be replaced according to the air volume changes input in real time by air volume sensor 1, air volume sensor 2 and air volume sensor 3, and control the replacement mechanism to replace the post-filter mechanism.

The rotor shaft of the motor 17 is connected to the rotating shaft 18 by an interference key, and the rotating shaft 18 is rotatably arranged on the middle side of the changing box 16 in a bearing-supported manner. The rotating shaft 18 is connected to the changing rotating frame 19 by an interference key. The outer edge of the changing rotating frame 19 is evenly provided with mounting holes 20 in an annular direction. The mounting holes 20 are used for slidingly inserting the rear filter mechanism. The sealing resin glue is used to bond the sealing pressure ring 21 in the step groove at the left end of the mounting hole 20. The material of the sealing pressure ring 21 is chloroprene rubber. A movable tube 1 35 is slidably inserted on the left side of the upper part of the change box 16, and an air volume sensor 2 36 is screwed on the movable tube 1 35. The left end of the movable tube 1 35 is connected to the access hose 15 by a throat clamp, and a pressing convex ring 2 351 is integrally provided on the right end of the movable tube 1 35.

The double rotor shaft flange of the motor 2 39 is connected to the screw rod 40, and a moving seat 41 is screwed on the screw rod 40. The bottom of the moving seat 41 is bolted to fix the sliding block 42, and the sliding block 42 is an inverted T-shaped block structure. The left and right sides of the top of the change box 16 are provided with sliding grooves, which are inverted T-shaped grooves. The sliding block 42 is slidably set in the sliding grooves. The sides of the moving seat 41 are bolted to fix the connecting frame 43, and the lower ends of the two connecting frames 43 are bolted to the movable tube 1 35 and the movable tube 2 37 respectively; The screw directions of the screw rods 40 and the movable seats 41 on both sides are set to meet the following conditions: when the motor 2 39 rotates clockwise, the movable seats 41 on both sides can be driven to move in opposite directions to the left and right sides; when the motor 2 39 rotates counterclockwise, the movable seats 41 on both sides can be driven to move toward each other; Therefore, by controlling the forward and reverse rotation of motor 2 39, movable tube 1 35 and movable tube 2 37 can be driven to move toward each other and to the left and right sides in opposite directions, thereby realizing the switching operation of sealing and connecting the two pipe sections with the rear filter mechanism loaded in the mounting hole 20 and reverse separation.

[0030] By setting the encoder 182, the rotation angle of the rotary shaft 18 can be monitored in real time, thereby providing a reliable angle basis for the subsequent running speed of the motor 17.

[0031] See also Figure 2 , Figure 4 , Figure 5 , Figure 6 The rear filter mechanism includes a filling tube 201 slidably inserted into the mounting hole 20, a pressing tube 22 is integrally provided at the left end of the filling tube 201, an isolation mesh plate 23 is fixed by screws on the right side of the pressing tube 22, and the mesh diameter of the isolation mesh plate 23 is 0.3 mm, and a filter plate 24 is fixed by screws at the end of the pressing tube 22, and the mesh diameter of the filter plate 24 is 2 mm; A sterilizing filter layer 25 is filled in the filling tube 201. The sterilizing filter layer 25 is a ceramic filter layer with a thickness of 5 cm and a filtration accuracy of 0.22 microns. One end of the sterilizing filter layer 25 is covered with a spacer mesh 26. The spacer mesh 26 is an acetate fiber filter membrane with a filtration accuracy of 0.2 microns. The sterilizing filter layer 25 first performs mold filtration, and then the spacer mesh 26 performs secondary mold filtration, so as to effectively remove the air mold sucked into the filling tube 201. One end of the spacer mesh 26 is supported and pressed by a retaining ring 27. The outer edge of the retaining ring 27 is tightly fitted with the inner wall of the filling tube 201. A transparent tube 28 is integrally arranged in the middle of the retaining ring 27. The transparent tube 28 is a circular porous tube. The right end of the transparent tube 28 is closed, and the diameter of the small hole is 0.2 mm. A dewatering layer 29 is arranged on one side of the retaining ring 27 and the dewatering layer 29 is coated on the transparent tube 28. The dewatering layer 29 5A is formed by accumulating and pressing molecular sieve particles in a filling tube 20, with a particle size of 0.5 mm. When the air that has been filtered by bacteria is discharged into a dewatering layer 29 through a porous tube 28, the dewatering layer 29 absorbs moisture in the air, thereby effectively reducing the moisture content in the air. One side of the dewatering layer 29 is covered with a partition mesh 30, which is a nylon filter layer with a thickness of 2 mm, and is used to prevent the dewatering layer 29 and the dewatering layer 31 from intersecting with each other. A dewatering layer 31 is set on one side of the partition mesh 30. The dewatering layer 31 is a 13X molecular sieve filled in a filling tube 201 and pressed, with a particle size of 0.3 mm. The dewatering layer 31 on the other side of the partition mesh 30 further absorbs the moisture contained in the air, and is matched with the dewatering layer 29 to achieve double-stage water filtration, thereby effectively reducing the air humidity. A sealing ring 101 is installed in the step at the other end of the filling tube 201. The sealing ring 101 is made of chloroprene rubber. A screw cap 32 is also threadedly locked in the step of the filling tube 201. The screw cap 32 presses the sealing ring 101 to achieve sealing between the screw cap 32 and the filling tube 201.

The humidity signal receiving module, the air volume signal receiving module 1, the air volume signal receiving module 2 and the air volume signal receiving module 3 are connected to the analysis and processing module through transmission. The analysis and processing module is bidirectionally connected to the mapping processing module. The signal input pin of the mapping processing module is connected to the signal input end of the industrial computer 53 through a signal line. The analysis and processing module is connected to the angle pulse signal receiving module through transmission. The transmission line of the encoder 182 is connected to the signal input pin of the angle pulse signal receiving module. The mapping processing module is used to share the processing process information and processing result information of the analysis and processing module with the industrial computer 53 in real time, and issue a temporary control signal to the analysis and processing module through the industrial computer 53. The mapping processing module connects the data of the analysis and processing module in the development board 55 with the industrial computer 53, and displays the processing process in a table format. data changes, therefore, the action humidity data and the action mold content data can be set by the industrial computer 53, and the predetermined operation parameter values ​​in the driver and integrated relay operation programs can also be set; the integrated relay control program and the driver control program are loaded in the industrial computer 53, and the control bits of the integrated relay control program and the driver control program are matched with all integrated relays and drivers respectively; the angle pulse signal receiving module is used to receive the angle pulse signal input from the encoder 182 in real time, and the analysis and processing module converts the angle pulse signal into an angle value, and calculates the angle change value in real time, so the encoder 182 monitors the rotor shaft rotation operation angle value of the motor 17 in real time, and because the feedback is the real-time angle change value, it can be substituted into the control motor 17 operation; The analysis and processing module is connected to the number relay processing module, and the number relay processing module is connected to the relay signal control and transmission module 1 and the relay signal control and transmission module 2. The analysis and processing module converts the humidity signal uploaded by the humidity sensor 58 in different areas into humidity data in real time, and converts the mold content information uploaded by the mold voc sensor in different areas into data formed after the conversion, and compares them with the action humidity data and the action mold content data respectively. When the action humidity data or the action mold content data is reached, the number relay processing module is connected to the area number, and the relay signal control and transmission module 1 and the relay signal control and transmission module 2 of the corresponding area number are issued an on-off instruction; the relay signal control and transmission module 1 is used to control the on-off of the electromagnetic valve 1 5, and the relay signal control and transmission module 2 is used to control the on-off of the electromagnetic valve 2 50. The signal output pins of the relay signal control and transmission module 1 and the relay signal control and transmission module 2 are respectively connected to the signal input ends of the two integrated relays through signal lines; It is worth noting that the signals uploaded by the humidity sensors 58 and mold voc sensors on different compact racks are all accompanied by the compact rack number. Therefore, after analysis and processing by the analysis and processing module, the guidance number relay processing module connects to the relay signal control and transmission module 1 and the relay signal control and transmission module 2 with the corresponding number to issue the opening and closing valve control instructions.

[0038] When the analysis and processing module is running, the action humidity data is U, and the setting range of the action humidity data U is 40%-48%. The real-time humidity data are Y 1、 Y 2、 Y 3。。。。。。 Y n , n is a positive integer, and n belongs to any compact rack number, when Y n When Y<U, the relay processing module keeps sending valve closing instructions to the relay signal control and transmission module 1 and the relay signal control and transmission module corresponding to the number n. n≥ At U, the relay processing module issues a valve opening command to the relay signal control and transmission module 1 and the relay signal control and transmission module corresponding to the number n; The action mold content data is F, and the setting range of the action mold content data F is 1000CFU / m³-1600CFU / m³. The two groups of mold content data obtained in real time are L 1、 L 2、 L 3。。。。。。 L n and R 1、 R 2、 R 3。。。。。。 R n , n is a positive integer, and n belongs to any dense rack number, L represents the mold content data obtained by the mold VOC sensor on the left, and R represents the mold content data obtained by the mold VOC sensor on the right. When (L n +R n) / 2<F, the relay processing module keeps issuing valve closing instructions to the relay signal control and transmission module 1 and the relay signal control and transmission module corresponding to the number n. When (L n +R n ) / 2≥F, the relay processing module issues a valve opening instruction to the relay signal control and transmission module 1 and the relay signal control and transmission module corresponding to the number n; During the treatment, Y n <U and (L n +R n ) / 2<F, the relay processing module issues a valve closing instruction to the relay signal control and transmission module 1 and the relay signal control and transmission module corresponding to number n.

[0039] The analysis and processing module is also connected to the relay signal control module 3, the speed control module 1, the speed control module 2, the steering speed control module 1, the steering speed control module 2 and the steering speed control module 3. After receiving the speed control signal input by the industrial computer 53 and the air volume information input by the air volume sensor 12, the air volume sensor 2 36 and the air volume sensor 3 38 in real time, the analysis and processing module issues speed control instructions to the speed control module 1 and the speed control module 2 respectively, and also issues a scrapping instruction for the primary filter mechanism and the post-filter mechanism to the industrial computer 53 through the mapping processing module, and controls the steering speed control module 1, the steering speed control module 2 and the steering speed control module 3 to issue an instruction for replacing the post-filter mechanism with the replacement mechanism; When the driving motors of the vacuum pump 13 and the vacuum pump 2 473 are both running at a speed of 600r / min, the standard air volume threshold QW-QT and the standard air volume difference threshold JG-JK are stored in the analysis and processing module for analysis and comparison. The air volume data input in real time by the air volume sensor 12 is A, the air volume data input in real time by the air volume sensor 2 36 is B, and the air volume data input in real time by the air volume sensor 3 38 is C. When A<QW or is between QW-QT and A<QT, the analysis and processing module will not send a primary filter mechanism scrapping instruction to the industrial control computer 53 through the mapping processing module. When A≥QT, the analysis and processing module will not send a primary filter mechanism scrapping instruction to the industrial control computer 53 through the mapping processing module. A command to scrap the primary filter mechanism is issued, and a zero speed control command is issued to the speed control module 1 and the speed control module 2; when BC<JG or is between JG-JK and BC is less than JK, the analysis and processing module will not issue a command to scrap the post-filter mechanism to the industrial computer 53 through the mapping processing module. When BC≥JK, the analysis and processing module issues a command to scrap the post-filter mechanism to the industrial computer 53 through the mapping processing module. In addition, the analysis and processing module also stores the risk air volume value DG. When any value of A, B, or C is ≤DG, the analysis and processing module issues an overall shutdown command to the industrial computer 53 through the mapping processing module, and a zero speed control command is issued to the speed control module 1 and the speed control module 2.

[0040] When the analysis processing module is analyzing, Y n≥ 1.3*U or (L n +R n ) / 2≥1.5*F, the analysis and processing module issues speed control instructions to the speed control module 1 and the speed control module 2 to control the drive motors of the vacuum pump 13 and the vacuum pump 2 473 to run alternately at 900r / min and 600r / min, that is, the drive motor of the vacuum pump 13 runs at 900r / min for 2 minutes, and then the drive motor of the vacuum pump 2 473 runs at 600r / min for 2 minutes, and so on alternately.

[0041] Therefore, when the air humidity in the compact shelving area and the amount of mold colonies in the air meet the requirements that long-term storage of archives in the compact shelving will not cause the archives to become damp and moldy, primary filtration and post-filtration are not performed; when the air humidity in the compact shelving area and the amount of mold colonies in the air reach the requirements that long-term storage of archives in the compact shelving will cause the archives to become damp and moldy, primary filtration and post-filtration are performed, and when the air humidity and the amount of mold colonies in the air exceed the standard, the primary filtration and post-filtration processes are accelerated.

[0042] The relay signal control module three is used to control the on and off of the electromagnet 47 in real time. The signal output pin of the relay signal control module three is connected to the integrated relay signal input end electrically connected to the electromagnet 47 through a signal line; the speed control module one and the speed control module two are respectively used to control the speeds of the vacuum pump one 13 and the vacuum pump two 473. The signal output pins of the speed control module one and the speed control module two are respectively connected to the driver signal input end electrically connected to the vacuum pump one 13 and the vacuum pump two 473 through signal lines; the steering rotation numerical control input module one is used to control the operation of the motor one 17, and the speed of the motor one 17 is set to 10r / min. The steering rotation numerical control input module two is used to control the operation of the electric telescopic rod 45. The steering rotation numerical control input module three is used to control the operation of the motor two 39. The signal output pins of the steering rotation numerical control input module one, the steering rotation numerical control input module two and the steering rotation numerical control input module three are respectively connected to the driver signal input end electrically connected to the motor one 17, the electric telescopic rod 45 and the motor two 39 through signal lines.

[0043] When the analysis and processing module issues an instruction to scrap the rear filter mechanism, the analysis and processing module will reduce the feed increment of the scrapped rear filter mechanism in the replacement rotary rack 19, that is, when all the rear filter mechanisms in all the installation holes of the replacement rotary rack 19 are available, the feed increment is 6, and the feed increment is reduced by 1 each time a rear filter mechanism is scrapped. The analysis and processing module sends a command to the steering CNC input module to allow the motor 17 to run clockwise by 1 / 6r. After a delay of 3 seconds, the cavity change mode is operated in this way. The cavity change mode operates as follows: first, a command to the steering CNC input module 3 to allow the motor 2 39 to run clockwise, and the movable tube 1 35 and the movable tube 2 37 are reversely separated from the top rear filter mechanism. After the command is completed, a command to the steering CNC input module to allow the motor 17 to run clockwise by 1 / 6r. At this time, the top rear filter mechanism is replaced. After the command is completed, a command to the steering CNC input module 3 to allow the motor 2 39 to run reversely, and the movable tube 1 35 and the movable tube 2 37 are sealed and connected to the replaced top rear filter mechanism.

[0044] Among them, the execution of the forward rotation command and reverse rotation command of the motor 2 39 issued by the numerical control input module 3 must meet the following requirements: after the forward rotation of the motor 2 39 is completed, the movable tube 1 35 and the movable tube 2 37 and their end connecting components are completely separated from the two ends of the rear filter mechanism and completely separated from the mounting hole; after the reverse rotation of the motor 2 39 is completed, the movable tube 1 35 and the movable tube 2 37 and their end connecting components are effectively sealed and docked with the two ends of the rear filter mechanism in the mounting hole.

[0045] When all the rear filter mechanisms in the mounting holes of the replacement rotary rack 19 are completely scrapped, the feed increment is 0, and the return increment is 6. Each time a rear filter mechanism is completely withdrawn from the replacement rotary rack 19, the return increment decreases by 1. When the return increment is 6 and no operation of withdrawing the rear filter mechanism is performed, the steering speed control instruction of the motor 17 running clockwise by 1 / 6r is not sent to the steering CNC input module. When the return increment starts from 5, the return increment is reduced by 1, that is, the motor 17 is sent to the steering CNC input module. 17 reverse running 1 / 6r steering speed control instruction, after a delay of 3 seconds, when the mode starts to be executed, a zero speed control instruction is first issued to the speed control module 1 and the speed control module 2. After the execution is completed, a forward running instruction of the motor 2 39 is issued to the steering CNC input module 3. After the forward running instruction is executed, the analysis and processing module no longer issues instructions to the steering CNC input module 3, but waits for the steering speed control instruction issued by the industrial computer 53 and input by the mapping processing module to determine the execution. When entering the continuous cavity withdrawal mode, the relay signal control input module 3, the steering CNC input module 1, and the steering CNC input module 2 will be controlled to operate. The continuous cavity withdrawal mode operates as follows: first, the relay signal control input module 3 issues a power-on command to the electromagnet 47. After the command is executed, the steering CNC input module 2 issues a maximum extension command for the electric telescopic rod 45 top rod. After the execution is completed, the steering CNC input module 2 issues a minimum retraction command for the electric telescopic rod 45 top rod. At this time, the bottom rear filter mechanism is completely pulled to the upper part of the export slide frame 44. After the command is executed, the relay signal control input module 3 issues a power-off command to the electromagnet 47, the return increment is reduced by 1, and the delay is 2 seconds. The steering CNC input module 1 issues a steering speed control command for the motor 17 to run 1 / 6r in reverse. After the execution is completed, the above actions are repeated until all rear filter mechanisms have completely withdrawn from the replacement rotating frame 19, and the mapping processing module sends a signal to the industrial computer 53 that all rear filter mechanisms have withdrawn.

[0046] During this operation, the angle pulse signal obtained in real time by the encoder 182 is converted into corresponding angle data by the analysis and processing module. In the cavity change mode and the continuous cavity withdrawal mode, after a single forward or reverse operation is completed, the motor 17 is controlled by the analysis and processing module to be within a 60° angle change value. From the beginning to the end of a single forward or reverse rotation, the angle change value monitored by the encoder 182 is calculated. If it is 60°, the analysis and processing module does not issue an angle adjustment command to the steering CNC input module. If it is not 60°, the analysis and processing module issues an angle adjustment command to the steering CNC input module. Issue an angle adjustment command, and the angle adjustment command operates as follows: based on the original operating direction of this mode, when the angle value fed back and converted by the encoder 182 is higher than V, issue a reverse operating command to the steering CNC input module 1, and stop when the feedback degree from the encoder 182 is V; when the angle value fed back and converted by the encoder 182 is lower than V, issue a same direction operating command to the steering CNC input module 1, and stop when the progress degree from the encoder 182 is V. After the adjustment command is completed and a corresponding delay is performed, the next operating command is issued.

[0047] When the operation of manually adding the rear filter mechanisms to the mounting holes of the replacement rotating frame 19 one by one is performed, two management personnel can operate it. After one person horizontally inserts a rear filter mechanism from the installation hole to the mounting hole, the other person can operate the industrial computer 53 to issue a clockwise operation 1 / 6r instruction to the CNC input module. After the first rear filter mechanisms are filled and the manual adjustment is completed, the accumulated feed increment in the analysis and processing module is 2. The operation is continued in this manner until all the mounting holes are filled with rear filter mechanisms, and the accumulated feed increment in the analysis and processing module is 6.

[0048] In conjunction with the setting of the environmental control system, the central air-conditioning setting temperature of the archive warehouse is 14°C-24°C, and the dehumidification setting is performed. Secondly, the environmental control system, except for the connecting hose 52 and the connecting hose 4, can be placed outside the archive warehouse, and an equipment room can be configured outside the archive warehouse, and a power distribution room for power supply can be configured in the equipment room. The system can be arranged in the equipment room according to the layout position of each row of compact shelving.

[0049] In summary, the suction duct 59 and the exhaust duct 60 are arranged in parallel above both sides of each compact rack. When the air humidity in the compact rack area and the amount of mold colonies in the air reach the threshold value that will cause the archives to become damp and moldy after long-term storage, the control mechanism will automatically start the suction pump 13 and the suction pump 2 473, and control the suction duct 59 in the corresponding area to inhale air from one side of the compact rack, filter larger impurities through the primary filter mechanism, then filter bacteria twice and perform two-stage water absorption treatment through the post-filter mechanism, and finally discharge it from the other side of the compact rack through the exhaust duct 60, so as to realize the circulating filtration treatment of the air in the compact rack area and more effectively perform sterilization and dehumidification. Therefore, a single system can meet the operation of automatic dehumidification and sterilization of the air in multiple compact rack areas; By using the control mechanism in conjunction with various air volume sensors, the system can monitor the filtering efficiency of the primary filtering mechanism and the post-filtering mechanism in real time, and when they reach a scrapped state, immediately send a replacement instruction to the industrial computer 53 so that the management personnel can understand and take measures in time; especially under the control of the control mechanism, when the replacement mechanism is used in conjunction with multiple post-filtering mechanisms, the post-filtering mechanism can be automatically replaced, and after all the post-filtering mechanisms in the replacement mechanism are scrapped, all the post-filtering mechanisms are discharged. Under this setting, a single loading of the post-filtering mechanism can be achieved, which can achieve longer use and a high degree of automation. In addition, the primary filtering mechanism and the post-filtering mechanism can be mass-produced by the factory and recycled by the factory after being scrapped. They can be installed as a whole during installation, which is convenient for management personnel to perform management operations.
