Technical Field

[0001] The invention relates to the technical field of temperature and humidity monitoring of a shielding cabinet, and more specifically, to a temperature and humidity monitoring device of a shielding cabinet. Background Art

[0002] Shielded cabinets are devices used to protect electronic equipment from electromagnetic interference and radio frequency interference. Usually composed of side walls, top plates, bottom plates, and back plates, they are usually used in data centers, laboratories, communication equipment rooms, and other environments to ensure the normal operation of equipment and data security. Shielded cabinets are usually placed in shielded cabinet rooms, and their temperature and humidity will be affected by the external environment. The temperature and humidity in the shielded cabinet have an important impact on equipment operation and data security, so it is very important to monitor the temperature and humidity in the shielded cabinet.

[0003] In actual use, the temperature and humidity inside the shielded cabinet will affect the electronic components such as servers and switches placed inside. Excessive temperature will affect the performance and life of the equipment. High temperature may cause electronic components to overheat and increase the failure rate. In addition, the impact of humidity should not be underestimated. High humidity environment is prone to corrosion and oxidation of metal parts, affecting the stability and life of the equipment. Low humidity environment is prone to static electricity, which may damage sensitive electronic components.

[0004] Temperature and humidity can cause damage to electronic components to a certain extent, but there are more important problems to be solved. Shielded cabinets are usually placed in shielded cabinet rooms. The shielded cabinet room is usually a normal temperature environment. Its temperature and humidity are greatly affected by the external environment. When there is a large temperature difference between the inside and outside of the shielded cabinet, condensation may appear inside the shielded cabinet. The appearance of condensation can cause short circuit or corrosion of the equipment, resulting in serious consequences.

[0005] Therefore, it is necessary to set up a temperature and humidity monitoring device for the shielding cabinet, which can monitor the temperature and humidity inside the shielding cabinet in real time and solve the problem of condensed water inside the shielding cabinet.

[0032] Among them, the temperature and humidity package feedback, including each group of temperature and humidity packages, will take the average value of each group of temperature and humidity data in the feedback time period within the first sliding time period of each group of temperature and humidity monitoring.

[0033] The present invention is further configured as follows: the analysis unit receives the information group of the temperature and humidity monitoring unit in a feedback time period, uses a sliding time period as the analysis period of the information group, performs a data analysis once in each sliding time period, and sends feedback information based on dew point judgment.

The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0060] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meanings as commonly understood by ordinary technicians in the technical field to which this application belongs.

[0061] See also Figure 1-Figure 8 , the present invention provides the following technical solutions:

[0062] Example 1, see Figure 1-Figure 8 A temperature and humidity monitoring device for a shielded cabinet comprises: an air cooling unit 2, two groups of temperature and humidity monitoring units 3, at least two groups of mounting columns 16, a scraping unit 4, a water cooling unit 5 and a control unit 6, wherein the air cooling unit 2 is arranged on the inner wall of the top plate 12 of the shielded cabinet; the air cooling unit 2 can dissipate heat for the entire shielded cabinet, thereby dissipating heat for all electronic components placed in the shielded cabinet. Two groups of temperature and humidity monitoring units 3 are arranged on the two side walls 11 of the shielded cabinet; the two groups of temperature and humidity monitoring units 3 can monitor the temperature and humidity inside the shielded cabinet and provide real-time data feedback. Two groups of mounting columns 16 are arranged inside the shielded cabinet and are symmetrically fixed on the side walls 11 of the shielded cabinet. The mounting columns 16 provide an installation environment for the water cooling unit 5.

[0063] It should be further explained that the scraping unit 4 is installed on the side wall 11 and the back plate 15 of the shielding cabinet. The scraping unit 4 can scrape the condensed water condensed on the side wall 11 and the back plate 15 to prevent the condensed water from dripping and damaging the electronic components. The water cooling unit 5 is horizontally inserted between the two mounting columns 16. The server with the highest temperature during actual use is placed at the water cooling unit 5 to centrally dissipate heat for the server to avoid damage to the server due to high heat. The control unit 6 is installed on the side of the side wall 11 away from the two groups of temperature and humidity monitoring units 3. The control unit 6 is electrically connected to the air cooling unit 2, the temperature and humidity monitoring unit 3, the scraping unit 4, and the water cooling unit 5, and can control the air cooling unit 2, the temperature and humidity monitoring unit 3, the scraping unit 4, and the water cooling unit 5 to operate through the control system built into the control unit 6.

[0064] See also Figure 4 The temperature and humidity monitoring unit 3 is arranged on both sides of the side wall 11. The temperature and humidity monitoring unit 3 includes a monitoring slide rail 31 arranged on the side wall 11 corresponding to the shielding cabinet in the vertical direction. A monitoring slider 32 is slidably connected to the monitoring slide rail 31. The monitoring slider 32 can be displaced in the vertical direction relative to the monitoring slide rail 31. A temperature and humidity monitoring head 33 is connected to the monitoring slider 32. The temperature and humidity monitoring head 33 can monitor the temperature and provide temperature and humidity feedback in each feedback time period.

[0065] See also Figure 4 , Figure 5 The scraping unit 4 includes a scraping rail 41 arranged on the corresponding side wall 11 of the shielding cabinet along the vertical direction, and a scraping slider 42 is slidably connected to the scraping rail 41. The scraping slider 42 can move vertically relative to the scraping rail 41. Two groups of scraping plates 43 are symmetrically arranged on the scraping slider 42. The scraping slider 42 can move vertically relative to the scraping rail 41, and can drive the two groups of scraping plates 43 to slide against the side wall 11 and the back plate 15, so as to scrape off the condensed water condensed thereon. The scraping rail 41 is arranged in parallel with the monitoring rail 31, and the scraping rail 41 is arranged between the two monitoring rails 31.

[0066] See also Figure 3Two groups of ventilation holes 22 are provided on the mounting plate 21. The two groups of ventilation holes 22 are symmetrically arranged. A group of fans 23 are respectively installed on the two groups of ventilation holes 22. The fans 23 can exchange air, speed up the air circulation speed inside the shielding cabinet, and reduce the overall temperature inside the shielding cabinet. A dustproof plate 24 is installed at a section of the fan 23 away from the mounting plate 21. The dustproof plate 24 prevents dust from the outside of the shielding cabinet from entering the inside of the shielding cabinet and prevents dust from falling on the electronic components inside the shielding cabinet. A top mounting plate 25 is installed at one end of the dustproof plate 24 away from the fan 23. The top mounting plate 25 and the dustproof plate 24 provide an installation environment. A group of air outlets 26 are respectively provided on the top mounting plate 25 corresponding to the position of the dustproof plate 24. The air outlets 26 serve as the inlet and outlet of air flow exchange. The air flow in the shielding cabinet can be discharged in and out through the two groups of ventilation holes 22 and the air outlets 26, thereby accelerating the air exchange speed.

[0067] See also Figure 6 A receiving plate 44 is installed on the bottom plate 13, and the receiving plate 44 can collect the condensed water scraped off by the scraping unit 4. A water diversion groove 45 is opened around the receiving plate 44, and the water diversion groove 45 can collect and flow out the condensed water. The water diversion groove 45 can receive the top of the receiving plate 44. Three groups of supporting feet 46 are respectively arranged at symmetrical positions. The three groups of supporting feet 46 can ensure that electronic components can still be placed at the bottom of the shielding cabinet without contacting condensed water.

[0068] Specifically, by sliding the scraper plate 43 on the scraper unit 4 in the vertical direction, the condensed water on the side wall 11 and the back plate 15 can be scraped off, and the scraped condensed water flows into the receiving plate 44. The receiving plate 44 can collect the condensed water scraped off by the scraper unit 4. After the collection is completed, the condensed water received on the receiving plate 44 can flow out through the water inlet trough 45, and thus be discharged from the shielding cabinet, thereby further reducing the humidity inside the shielding cabinet.

[0069] The water cooling unit 5 includes two groups of cooling plates 51, which are arranged at a certain distance. The distance between the two groups of cooling plates 51 can accommodate the server with the highest operating temperature. A water cooling groove 52 is opened on each group of cooling plates 51, and the water cooling groove 52 can allow cooling water pipes to pass through. The water cooling groove 52 is arranged in a bow-shaped structure to increase the contact area between the cooling water pipe and the server.

[0070] The control unit 6 has a built-in control system, including a temperature and humidity monitoring unit, which monitors the temperature and humidity changes in the shielding cabinet in real time, and aggregates the temperature and humidity information into an information group for transmission; the temperature and humidity monitoring unit can monitor the temperature and humidity inside the shielding cabinet.

[0071] The analysis unit receives the information group transmitted by the temperature and humidity monitoring unit, analyzes and disassembles the information group, and sends feedback information based on the analysis and disassembly results. The analysis unit can calculate the dew point temperature of the current environment of the shielding cabinet through calculation, and analyze the difference between the dew point temperature and the temperature of the shielding cabinet to determine whether condensation water accumulation occurs.

[0072] The temperature and humidity control unit receives the feedback command transmitted by the analysis unit, responds accordingly, and sends control signals to the air cooling unit, the water cooling unit, and the scraping unit to control their operating power and start switches.

[0073] The temperature and humidity monitoring unit monitors the temperature and humidity in the shielding cabinet through the temperature and humidity monitoring head 33. The operator sets the sliding time period and the feedback time period. The temperature and humidity monitoring head 33 slides with the sliding time period as the active unit and the feedback time period as the signal transmission interval. In each sliding time period, the top temperature and humidity monitoring head 33 slides from top to bottom, and the bottom temperature and humidity monitoring head 33 slides from bottom to top. Both groups of temperature and humidity monitoring heads 33 slide to the center position without collision. After the sliding is completed, both groups of temperature and humidity monitoring heads 33 return to the initial position state, that is, the temperature and humidity are packaged into an information group and then fed back in each feedback time period; one sliding time period includes four groups of feedback time periods; and each group of sliding time period performs a temperature and humidity package feedback.

[0074] Among them, the temperature and humidity package feedback, including each group of temperature and humidity packages, will take the average value of each group of feedback time period temperature and humidity data within the first sliding time period of each group of temperature and humidity monitoring. Taking the average value avoids the condensation of condensed water in a certain place due to uneven temperature in the shielded cabinet and not being removed.

[0075] Data analysis is performed once per sliding time period and feedback information is sent based on the dew point judgment, where the dew point judgment is processed by dew point temperature calculation. The dew point calculation formula is:

[0076] ,

[0077] Wherein, T1, ...TN are the temperatures obtained in each sliding time period and the feedback time period, wherein N is the number of feedback time periods in one sliding period, so N=4; if the temperature changes rapidly, the monitoring frequency can be adjusted accordingly, so that the sliding time period can be shortened, and the value of N can be changed so that there are more feedback time periods in one sliding period, thereby accelerating the monitoring.

[0078] Among them, the temperature and humidity monitoring head 33 slides evenly, so the detection positions of T1, T2, T3, and T4 are evenly spaced, ensuring that the temperature and humidity of each layer of the shielding cabinet are measured, without false monitoring or missed monitoring, ensuring accurate monitoring.

[0079] In this embodiment, Tr is the dew point temperature, the unit is Celsius, RH is the relative humidity, the unit is percentage, a and b are constants, and specifically a=17.27 and b=237.7 are set.

[0080] There is a close relationship between dew point and condensation, and understanding the relationship between the two is crucial to controlling environmental humidity, preventing equipment damage, and ensuring data security. Dew point refers to the temperature at which water vapor in the air begins to condense into liquid water under a certain air pressure. Simply put, the dew point is the temperature at which water vapor in the air reaches saturation and begins to condense. When the temperature of the surface of an object is lower than the dew point temperature of the surrounding air, the water vapor in the air condenses into water droplets on the surface to form condensed water.

[0081] Under the same temperature conditions, the higher the humidity and the higher the dew point temperature, the easier it is for the water vapor in the air to reach saturation, making it easier to form condensed water.

[0082] If the calculated dew point temperature is higher than the monitored internal temperature of the shielding cabinet under dew point judgment, that is, the calculated dew point temperature is higher than the data fed back by the temperature and humidity package, then it is judged that the ambient temperature at this time meets the conditions for the formation of condensed water, and a startup message is sent to the condensed water treatment unit; if the condensed water treatment unit receives the startup message, the scraping unit 4 is controlled to slide in the vertical direction.

[0083] If the calculated dew point temperature is lower than the monitored internal temperature of the shielded cabinet under dew point judgment, that is, the calculated dew point temperature is lower than the data fed back by the temperature and humidity package, it is judged that the ambient temperature at this time does not meet the conditions for condensation water formation, and no information is sent to the condensation water treatment unit.

[0084] The temperature and humidity control unit includes a temperature control unit and a condensed water treatment unit. The temperature control unit adjusts the power of the air cooling unit 2 through the feedback information transmitted by the analysis unit. If the temperature is high, the operating power of the air cooling unit 2 is increased; if the temperature is low, the operating power of the air cooling unit 2 is reduced. The condensed water treatment unit controls the start time of the scraping unit 4 through the feedback information transmitted by the analysis unit.

[0085] Specifically, the temperature and humidity inside the shielding cabinet can be monitored by the temperature and humidity monitoring unit control unit, and the temperature and humidity monitoring head 33 is controlled to move by the control unit 6. The temperature and humidity monitoring head 33 completes a top-down slide within a sliding time period, wherein a sliding time period includes N feedback time periods (N=4), and temperature and humidity data are fed back once in one feedback time period, and temperature and humidity package feedback is performed once for four feedback temperature and humidity data in one sliding time period. Among them, the temperature and humidity package feedback includes each group of temperature and humidity package, and each group of temperature and humidity data in each feedback time period within one sliding time period of each group of temperature and humidity monitoring heads 33 is averaged. The temperature and humidity package feedback data is transmitted to the analysis module, and the analysis module judges the dew point thereof. If the dew point temperature is higher than the temperature and humidity package feedback data, the scraping unit 4 is started; if the dew point temperature is lower than the temperature and humidity package feedback data, the scraping unit 4 is not started.

[0086] Specifically, a method for using a temperature and humidity monitoring device of a shielded cabinet comprises the following steps:

[0087] S1. Setting a sliding time period and a feedback time period; wherein one sliding time period includes N feedback periods;

[0088] S2. In one sliding time period, the top temperature and humidity monitoring head 33 slides from top to bottom, and the bottom temperature and humidity monitoring head 33 slides from bottom to top, and both sets of temperature and humidity monitoring heads 33 slide to the center position; wherein, the temperature and humidity are packaged into an information group and then fed back in each feedback time period;

[0089] S3, perform a temperature and humidity package feedback once in each sliding time period, and feed the temperature and humidity package feedback to the temperature and humidity control unit;

[0090] S4. After receiving the temperature and humidity package feedback, the temperature and humidity control unit performs a dew point judgment;
