Description

Technical Field

[0001] The utility model relates to the field of warehouse temperature and humidity monitoring, in particular to a novel device for monitoring warehouse temperature and humidity. Background Art

[0002] Temperature and humidity will affect the quality of goods in the warehouse. Therefore, during the storage process, it is necessary to ensure the airtightness of the warehouse and adjust the temperature and humidity in the warehouse in time according to the temperature and humidity range suitable for goods storage to ensure normal storage of goods.

[0003] The current method of monitoring and adjusting the temperature and humidity in a warehouse is to install a thermometer and hygrometer in the warehouse, and have the warehouse keeper enter the warehouse regularly (for example, every day) to read the temperature and humidity values ​​displayed by the thermometer and hygrometer, and then adjust the temperature and humidity in the warehouse according to the temperature and humidity values ​​displayed by the thermometer and hygrometer.

[0004] When setting a temperature and humidity range suitable for storage of a certain item of goods to be stored, generally, the optimal temperature and humidity range (including the optimal temperature range and the optimal humidity range) that is most suitable for storing the goods is first selected within the temperature and humidity range suitable for storage of the goods; and within the temperature and humidity range suitable for storing the goods, the temperature and humidity interval that is lower or higher than the optimal temperature and humidity range is defined as a transition temperature and humidity range (including the transition temperature range and the transition humidity range).

[0005] Since the warehouse door needs to be opened and closed each time the value of the thermometer and hygrometer is read, the operation is inconvenient. According to many years of warehouse storage records, compared with warehouses with closed doors, the temperature and humidity inside the warehouse will have floating errors of 2%-3% and 3%-4% respectively when the warehouse door is opened and closed. This is because the warehouse door will form temperature pressure ventilation and wind pressure ventilation when it is opened and closed, causing unnecessary changes in the temperature and humidity inside the warehouse. The changes in temperature and humidity inside the warehouse will not only affect the storage status of the goods in the warehouse, but also interfere with the warehouse keeper's judgment on whether the temperature and humidity in the warehouse need to be adjusted.

[0033] The following will be combined with the attached Figures 1 to 3 The technical solution of a novel device for monitoring temperature and humidity in a warehouse of the utility model is described in detail with specific embodiments.

[0034] Example

[0035] like Figures 1 to 3 As shown, the novel device for monitoring temperature and humidity in a warehouse of this embodiment comprises an internal probe 11 installed in the warehouse for detecting temperature and humidity in the warehouse, an external probe 21 installed outside the warehouse for detecting ambient temperature and humidity outside the warehouse, and a thermometer and an identification mechanism installed outside the warehouse. Two thermometers and hygrometers are provided outside the warehouse, namely, an internal thermometer and hygrometer 1 and an external thermometer and hygrometer 2. The internal thermometer and hygrometer 1 is electrically connected to the internal probe 11, and the communication line between the two passes through the warehouse wall; the external thermometer and hygrometer 2 is electrically connected to the external probe 21. When the internal probe 11 and the external probe 21 are working, they collect the temperature and humidity data inside and outside the warehouse respectively, and the temperature and humidity data collected by the above two probes are respectively transmitted to the two thermometers and hygrometers outside the warehouse. The internal thermometer and hygrometer 1 displays the temperature and humidity data inside the warehouse in real time, and the external thermometer and hygrometer 2 displays the temperature and humidity data outside the warehouse in real time, which is convenient for the warehouse keeper to check on site. There is no need to open the warehouse door to understand the temperature and humidity conditions in the warehouse, avoiding the problem of temperature and humidity changes in the warehouse caused by the opening and closing of the warehouse door, ensuring that the goods in the warehouse are well preserved, and will not interfere with the warehouse keeper's judgment on whether the temperature and humidity in the warehouse need to be adjusted.

[0036] The identification mechanism in this scheme is described in detail as follows:

[0037] The identification mechanism includes a first dial assembly 3 for displaying the temperature and humidity inside the warehouse, and a second dial assembly 4 for displaying the ambient temperature and humidity outside the warehouse. Both dial assemblies include a fixed pointer 31, a group of turntables cooperating with the pointer 31, a driving unit for driving the turntables to rotate, and a controller 34 for controlling the operation of the driving unit. Each group of turntables includes a large-diameter turntable 32 and a small-diameter turntable 33 rotating coaxially. The surfaces of the two turntables are respectively provided with temperature scales 321 and humidity scales 331. The turntables are driven by the driving unit to rotate so that different temperature scales 321 and humidity scales 331 are aligned with the pointer 31. The dial assembly can be used to display temperature and humidity.

[0038] Taking the first dial assembly 3 as an example, the first dial assembly 3 is used to display the temperature and humidity values ​​in the warehouse. The large diameter turntable 32 and the small diameter turntable 33 are stacked together, and the small diameter turntable 33 is fixedly connected to the disk surface facing the large diameter turntable 32 with a rotating shaft 335 passing through the large diameter turntable 32, and the large diameter turntable 32 is provided with a through hole for the rotating shaft 335 to pass through, and the disk surface of the large diameter turntable 32 facing away from the small diameter turntable 33 is also fixedly connected with a rotating cylinder 325, and the rotating cylinder 325 is sleeved on the outside of the rotating shaft 335, and the axis of the rotating cylinder 325 and the rotating shaft 335 coincide. In this embodiment, both turntables rotate around the axis of the rotating shaft 335. The large diameter turntable 32 is provided with a temperature scale 321 indicating the temperature value on the disk surface facing the small diameter turntable 33, and the small diameter turntable 33 is provided with a humidity scale 331 indicating the humidity value on the disk surface facing away from the large diameter turntable 32. When the two turntables rotate, different temperature scales 321 and humidity scales 331 can be aligned with the pointer 31, so as to realize the function of using the two turntables to display the temperature value and the humidity value respectively. It should be understood that the scales set on the turntable surface can be processed on the turntable surface by etching, engraving, etc., or can be directly drawn on the turntable surface.

[0039] In this embodiment, both dial assemblies in this embodiment are fixedly mounted on a flat substrate 6. Still taking the first dial assembly 3 as an example, the two turntables of the first dial assembly 3 are rotatably mounted on the substrate 6. The rotating cylinder 325 of the large-diameter turntable 32 passes through the substrate 6 in a direction perpendicular to the substrate 6 and is rotatably matched with the substrate 6. The large-diameter turntable 32 is rotatably matched with the substrate 6 through the rotating cylinder 325, and the small-diameter turntable 33 is rotated relative to the rotating cylinder 325 through the rotating shaft 335. The pointer 31 of the first dial assembly 3 is fixedly connected to the plate surface of the substrate 6, and the length direction of the pointer 31 is perpendicular to the axis of the rotating shaft 335, and one end of the pointer 31 extends toward the axis of the rotating shaft 335. The pointer 31 is fixedly mounted on the substrate 6, and one end of the pointer 31 points to the axis of the turntable.

[0040] The temperature values ​​represented by all the temperature scales 321 on the large diameter turntable 32 are a group of temperature values ​​that increase in sequence, and each temperature scale 321 is evenly arranged around the axis of the large diameter turntable 32 according to the order of the temperature values ​​it represents. The temperature range between the lowest value and the highest value in this group of temperature values ​​is defined as the temperature range corresponding to the above temperature scale 321, and it should be ensured that the temperature range corresponding to this group of temperature scales 321 includes a temperature range suitable for cargo storage.

[0041] The humidity values ​​represented by all humidity scales 331 on the small-diameter turntable 33 are a group of humidity values ​​that increase in sequence, and each humidity scale 331 is evenly arranged around the axis of the small-diameter turntable 33 according to the order of the humidity values ​​it represents. The humidity range between the lowest value and the highest value in this group of humidity values ​​is defined as the humidity range corresponding to the above humidity scale 331, and it should be ensured that the humidity range corresponding to this group of humidity scales 331 includes a humidity range suitable for cargo storage.

[0042] Furthermore, when setting a temperature and humidity range suitable for storage for a certain item of goods to be stored, first, the optimal temperature and humidity range (including the optimal temperature range and the optimal humidity range) that is most suitable for storing the goods is selected within the temperature and humidity range suitable for storing the goods; and within the temperature and humidity range suitable for storing the goods, the temperature and humidity interval that is lower or higher than the optimal temperature and humidity range is defined as a transition temperature and humidity range (including the transition temperature range and the transition humidity range).

[0043] On the large diameter rotating disk 32, each temperature scale 321 represents a different temperature value. According to the temperature value indicated by each temperature scale 321, the temperature scales 321 in the optimal temperature range and the transition temperature range are selected, and the first temperature mark 322 is drawn in the area between the temperature scales 321 belonging to the optimal temperature range, the second temperature mark 323 is drawn in the area between the temperature scales 321 belonging to the transition temperature range, and the third temperature mark 324 is drawn in the area between all the remaining temperature scales 321. On the small diameter rotating disk 33, each humidity scale 331 corresponds to a different humidity value. According to the humidity value indicated by each humidity scale 331, the humidity scales 331 in the optimal humidity range and the transition humidity range are selected, and the first humidity mark 332 is drawn in the area between the humidity scales 331 belonging to the optimal humidity range, the second humidity mark 333 is drawn in the area between the humidity scales 331 belonging to the transition humidity range, and the third humidity mark 334 is drawn in the area between all the remaining humidity scales 331.

[0044] It should be understood that, in this embodiment, drawing a mark within the range between two scales refers to connecting the two scales with the axis of the turntable to form two lines, and drawing a mark in the arc area between the two lines.

[0045] The shapes of the temperature marks and humidity marks mentioned in this embodiment are all arc patterns, and the center of the arc pattern coincides with the axis of the turntable. The colors of the first temperature mark 322 and the first humidity mark 332 are both green, indicating that the temperature in the warehouse is in the optimal temperature range, and the humidity is in the optimal humidity range; the colors of the second temperature mark 323 and the second humidity mark 333 are yellow, indicating that the temperature in the warehouse is in the transitional temperature range, and the humidity is in the transitional humidity range, and it is necessary to arrange a work plan for adjusting the temperature and humidity in the warehouse in time; the colors of the third temperature mark 324 and the third humidity mark 334 are red, indicating that the temperature in the warehouse is in a temperature range that is not suitable for goods storage, and the humidity is in a humidity range that is not suitable for goods storage, and it is necessary to adjust the temperature and humidity in the warehouse immediately.

[0046] In addition, the controller 34 of the first dial assembly 3 is communicatively connected to the in-warehouse thermometer and hygrometer 1, and the controller 34 is installed on the substrate 6. The input port of the controller 34 is communicatively connected to the in-warehouse thermometer and hygrometer 1, and the output port is electrically connected to the driving unit, that is, the controller 34 controls the operation of the driving unit according to the in-warehouse temperature data and the in-warehouse humidity data transmitted by the in-warehouse thermometer and hygrometer 1, and drives the two turntables to rotate respectively, so that the scales on the turntables indicating the current in-warehouse temperature / humidity values ​​are aligned.

[0047] Specifically, the driving unit in this embodiment includes a first motor 326 and a second motor 336 bolted to the base plate 6, the first motor 326 and the second motor 336 are controlled by the controller 34, the output shaft of the first motor 326 and the rotating cylinder 325 are driven by a gear set, and the two gears of the gear set are respectively sleeved on the output shaft of the first motor 326 and the outer side of the rotating cylinder 325; the output shaft of the second motor 336 and the rotating shaft 335 are driven by another gear set, and the end of the rotating shaft 335 away from the small-diameter turntable 33 passes through the rotating cylinder 325, so that the gears can be easily installed. In addition, the transmission method between the above-mentioned two motors and the rotating shaft 335 and the rotating cylinder 325 can adopt a chain drive, a coupling drive, etc.

[0048] When the first dial assembly 3 is working, the controller 34 automatically drives the two turntables to rotate according to the operation of the temperature and humidity control driving unit in the warehouse, so that the temperature scale 321 indicating the current temperature value in the warehouse is aligned with the pointer 31; the humidity scale 331 indicating the current humidity value in the warehouse is aligned with the pointer 31. Subsequently, the warehouse keeper can directly observe the relative position relationship between the pointer 31 and the first temperature mark 322 / first humidity mark 332, intuitively judge whether the temperature and humidity in the warehouse are within the optimal temperature and humidity range, and know the degree of deviation of the temperature and humidity in the warehouse from the boundary of the optimal temperature and humidity range, so that the warehouse keeper can reasonably arrange the work plan for adjusting the temperature and humidity in the warehouse and the adjustment range.

[0049] In addition, even without using the controller 34 and the drive unit, the warehouse keeper can manually rotate the turntable to keep the temperature scale 321 indicating the current temperature value in the warehouse aligned with the pointer 31, and the humidity scale 331 indicating the current humidity value in the warehouse aligned with the pointer 31. However, it should be understood that if the controller 34 and the drive unit are used to automatically control the rotation of the large-diameter turntable 32 and the small-diameter turntable 33, the temperature scale 321 and the humidity scale 331 can be more accurately aligned with the pointer 31, and the warehouse keeper only needs to observe the turntable and does not need to rotate the turntable himself, which saves time and effort.

[0050] In addition, the identification mechanism also includes a second dial assembly 4 for displaying the ambient temperature and humidity outside the warehouse. The second dial assembly 4 is set with reference to the first dial assembly 3, and is also provided with a controller 34 installed on the substrate 6, a drive unit, a pointer 31, and a group of turntables matched with the pointer 31. The group of turntables also includes a large-diameter turntable 32 with a temperature scale 321 and a small-diameter turntable 33 with a humidity scale 331. The large-diameter turntable 32 and the small-diameter turntable 33 of the second dial assembly 4 cooperate with the pointer 31 to conveniently display the ambient temperature and humidity outside the warehouse. The controller of the second dial assembly 4 is connected to the thermometer and hygrometer 2 outside the warehouse for communication, and the drive unit is controlled to operate according to the temperature data and humidity data transmitted to the controller 34 by the temperature and humidity outside the warehouse. In addition, the two turntables of the second dial assembly 4 also refer to the turntable of the first dial assembly 3, and the first, second, and third temperature marks and the first, second, and third humidity marks are drawn, which can facilitate the warehouse keeper to understand the ambient temperature and humidity outside the warehouse, and assist the warehouse keeper to determine whether the temperature and humidity in the warehouse can be adjusted by opening the door or window.

[0051] In this embodiment, taking the storage of finished tobacco leaves in the redrying plant as an example, the optimal temperature required for the storage of finished tobacco leaves is 20-30°C, and the optimal humidity is 55%-65%. Therefore, the temperature range of 20-30°C can be set as the optimal temperature range, corresponding to the range of the first temperature mark 322; the temperature range of 15-20°C and 30-35°C can be set as the transition temperature range, corresponding to the range of the second temperature mark 323; and the temperature in the warehouse should avoid reaching the temperature range of 0-15°C and 35-95°C, and these two temperature ranges correspond to the range of the third temperature mark 324. In addition, for the humidity required for the storage of finished tobacco leaves, the optional optimal humidity range is 55%-65%, corresponding to the range of the first humidity mark 332; and the temperature range of 50%-55% and 65%-70% is used as the transition humidity range, corresponding to the second humidity range; the humidity in the warehouse should avoid reaching the temperature range of 0-50% and 70%-95%, and these two humidity ranges correspond to the range of the third humidity mark 334.

[0052] Furthermore, the device for monitoring the temperature and humidity of the warehouse in this embodiment also includes a communication module 5 and a monitoring terminal 51 or a server 52 that is communicatively connected to the communication module 5. The communication module 5 is electrically connected to both thermometers and hygrometers, and the temperature and humidity data measured by the two thermometers and hygrometers can be transmitted to the monitoring terminal 51 or the server 52.

[0053] If the monitoring terminal 51 is selected and the monitoring terminal 51 is connected to the communication module 5 for communication, the monitoring terminal 51 can be installed in the monitoring room. The monitoring terminal 51 includes a display module that displays the temperature and humidity inside the warehouse and the ambient temperature and humidity outside the warehouse in real time. The communication module transmits the temperature and humidity data measured by the two thermometers and hygrometers to the monitoring terminal 51, which is convenient for the warehouse keeper to understand the temperature and humidity conditions inside and outside the warehouse in the monitoring room. When the monitoring terminal 51 is running, it can establish a communication connection with the communication modules corresponding to multiple warehouses at the same time, and then receive the temperature and humidity data inside the warehouse and the ambient temperature and humidity data outside the warehouse of each warehouse, and display them on the same monitoring terminal 51, which can facilitate the warehouse keeper to conveniently manage the temperature and humidity of each warehouse.

[0054] If server 52 is selected, server 52 also needs to be configured with a corresponding user terminal 53. Server 52 includes a database module for storing temperature and humidity data, an analysis module for analyzing and comparing temperature and humidity data, and a communication module for transmitting data. Server 52 communicates with communication module 5 and user terminal 53 through the communication module, and transmits the temperature and humidity data measured by the two thermometers and hygrometers to server 52. Then the analysis module of server 52 runs to analyze whether the temperature and humidity in the warehouse are out of the optimal temperature and humidity range and the transition temperature and humidity range. If any of the temperature and humidity in the warehouse is out of the optimal temperature and humidity range / transition temperature and humidity range, it is necessary to send an alarm message to the user terminal 53 through the communication module to remind the warehouse keeper to adjust the temperature and humidity in the warehouse.

[0055] The above-mentioned monitoring terminal 51 or user terminal 53 can be installed in a portable terminal device to receive temperature and humidity data information and alarm information by wireless communication; non-portable PC and other equipment can also be selected, and the warehouse keeper can understand the temperature and humidity conditions inside and outside the warehouse from the monitoring room. However, no matter which type of monitoring terminal 51 or user terminal 53 is used, it can be adapted to the needs of remote monitoring and simultaneous monitoring of the temperature and humidity of multiple warehouses.

[0056] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described.
