Description

Technical Field

[0001] The present invention relates to the technical field of intelligent cabinets, and in particular to a temperature and humidity automatic adjustment system and method for an ACU cabinet. Background Art

[0002] An urban underground utility corridor is a tunnel constructed beneath a city, integrating various engineering pipelines such as electricity, communications, gas, heating, and water supply and drainage. It features dedicated inspection and lifting ports, as well as monitoring systems. It is uniformly planned, designed, constructed, and managed, and serves as a vital infrastructure and "lifeline" for urban operations. To ensure the stable operation of this vital infrastructure and "lifeline," urban underground utility corridors are equipped with numerous sensors, allowing control centers to remotely access and monitor data within the corridor to prevent disasters and accidents.

[0003] The Area Control Unit (ACU) is a regional control module currently deployed to meet the need for centralized management and transmission of extensive on-site monitoring data in urban underground utility corridors and cable tunnels. It integrates signal acquisition, local control, data exchange, and remote networking. It connects to sensors installed in urban underground utility corridors and transmits data to a control center. Urban underground utility corridors are tunnel spaces constructed underground in cities, characterized by high humidity and low temperatures. When relative humidity exceeds 80%, moisture condenses easily in the ACU cabinet, causing metal rust. For example, rust can cause rust on printed circuit board contacts within electronic components, increasing impedance and potentially shorting adjacent solder joints, leading to failures. When relative humidity is below 50%, the excessively dry air can easily generate static electricity. This static electricity can damage integrated circuit chips, causing electronic components to malfunction, thus affecting the proper functioning of the ACU. Summary of the Invention

[0004] One of the purposes of the present invention is to provide an automatic temperature and humidity adjustment system for an ACU cabinet, which can automatically adjust the temperature and humidity inside the ACU cabinet to avoid affecting the normal operation of the ACU area control module.

[0005] In order to achieve the above-mentioned object, a temperature and humidity automatic adjustment system for an ACU cabinet is provided, comprising an outer cabinet, an inner cabinet, and a control assembly, wherein the inner cabinet is arranged inside the outer cabinet, and a circulating air duct and an air compression assembly are arranged between the inner cabinet and the outer cabinet; an air storage box is arranged inside the circulating air duct, and the air compression assembly comprises an air compression device, a first air compression pipeline, and a second air compression pipeline; one end of the first air compression pipeline is connected to the air compression device, and the other end is connected to the inner cabinet; the air compression device is connected to the air storage box; one end of the second air compression pipeline is connected to the air storage box, and the other end is connected to the inner cabinet; the control assembly comprises:

[0006] Temperature and humidity detection module: used to detect the first temperature and humidity information in the air storage box and the second temperature and humidity information inside the inner cabinet;

[0007] Temperature and humidity adjustment module: used to determine whether the inner cabinet reaches the preset temperature and humidity adjustment threshold based on the second temperature and humidity information analysis. If so, the first air compression pipeline is controlled to connect the air compression equipment and the inner cabinet, and the air compression equipment is started to draw the air in the inner cabinet into the air storage box; it is also used to determine whether the gas inside the air storage box reaches the preset temperature and humidity input threshold through the first temperature and humidity information analysis after the set standing time is met. If so, the second air compression pipeline is controlled to connect the inner cabinet and the air storage box.

[0008] Principles and advantages:

[0009] 1. The setting of outer cabinet, inner cabinet and circulating air duct. The circulating air duct can draw in low-temperature air from the outside to form a circulation, thereby cooling the inner cabinet.

[0010] 2. The setting of the temperature and humidity detection module can detect the first temperature and humidity information in the air storage box and the second temperature and humidity information inside the inner cabinet in real time, so as to facilitate the temperature and humidity adjustment of the inner cabinet.

[0011] 3. The setting of the air storage box, air compression component and temperature and humidity adjustment module. When the temperature and humidity adjustment module finds through the detection data of the temperature and humidity detection module that the inner cabinet needs to be temperature and humidity adjusted, the air compression equipment in the air compression component can be controlled to extract the air in the inner cabinet through the first air compression pipe and send it to the air storage box, so that the inner cabinet is in a vacuum state, which can reduce the temperature and humidity in the inner cabinet.

[0012] 4. The arrangement of the second air compression pipe, air storage box, and temperature and humidity adjustment module. Since the electronic components in the inner cabinet continuously generate heat during operation, although there is a circulating air duct to cool the outer surface of the inner cabinet, the electronic components inside the inner cabinet are basically not in contact with the side walls of the inner cabinet, so the cooling effect is still not ideal, and the relative humidity is not easy to achieve, which is not conducive to the normal operation of the electronic components inside the inner cabinet. When the air compression equipment extracts the air from the inner cabinet and sends it to the air storage box, the air pressure in the air storage box increases, and the internal gas temperature will rise. The air storage box is arranged in the circulating air duct, so the circulating air duct will also cool the outside of the air storage box, so that the high-temperature and high-humidity air in the air storage box will condense into water droplets on the inner side wall of the air storage box, thereby achieving the effect of cooling and dehumidifying the air in the air storage box. If the gas inside the air storage box reaches the preset temperature and humidity input threshold, the second air compression pipe is controlled to connect the inner cabinet and the air storage box.

[0013] Since the air storage box is in a high-pressure state and the inner cabinet is in a low-pressure state, the gas in the air storage box can enter the inner cabinet at a higher speed and fill the inner cabinet. At this time, the temperature and humidity of the gas in the air storage box are adjusted, and it can absorb heat from the inside. Combined with the external cooling effect of the circulating air duct, it can achieve automatic and efficient adjustment of temperature and humidity, thereby avoiding excessively high or low temperature and humidity affecting the normal operation of the ACU area control module.

[0014] Furthermore, the temperature and humidity detection module is further used to detect third temperature and humidity information at the connection point between the second air compression pipe and the inner cabinet;

[0015] The second air compression pipe is provided with a plurality of openings, each of which is provided with an inclined baffle; the opening is provided with a first solenoid valve whose opening is located in the circulating air duct; the control component further includes:

[0016] Temperature and humidity fine-tuning module: used to adjust the opening and closing and opening degree of the first solenoid valve according to the third temperature and humidity information feedback.

[0017] Since the air storage box is in a high-pressure state and the inner cabinet is in a low-pressure state, the gas in the air storage box can enter the inner cabinet at a higher speed. In addition, a number of openings and inclined baffles are provided on the second air compression pipe. According to the Bernoulli principle, the higher the speed, the lower the pressure. Therefore, the low-temperature and high-humidity gas in the circulating air duct will enter the second air compression pipe from the opening, thereby adjusting the original temperature and humidity in the second air compression pipe. The temperature and humidity fine-tuning module is then used to adjust the opening and closing and opening of the first solenoid valve according to the third temperature and humidity information feedback, so that the temperature and humidity of the gas entering the inner cabinet can be adjusted more accurately, thereby ensuring the stability of the internal environment of the inner cabinet.

[0018] Furthermore, the second compressed air pipeline is a square-wave U-shaped pipeline, a shortcut channel is provided at the U-shaped inflection point of the second compressed air pipeline, and a second solenoid valve is provided on the shortcut channel;

[0019] The temperature and humidity fine adjustment module is further used to adjust the opening and closing of the second solenoid valve according to the third temperature and humidity information feedback.

[0020] The second compressed air duct is a square-wave U-shaped duct, and a shortcut channel is provided at the U-shaped inflection point of the second compressed air duct. This allows the low-temperature, high-humidity gas in the circulating air duct to be used to cool the gas in the second compressed air duct. If the temperature needs to be adjusted to a lower level, the second solenoid valve is closed, allowing the gas in the second compressed air duct to pass through the interior for a longer time. If the temperature needs to be adjusted to a higher level, the second solenoid valve is opened, allowing the gas in the second compressed air duct to pass through the interior for a shorter time. This allows the temperature of the gas entering the inner cabinet to be adjusted more accurately, thereby ensuring the stability of the internal environment of the inner cabinet.

[0021] Furthermore, a fan is provided in the circulating air duct, and a heat sink is provided around the outer side of the inner cabinet, and the end of the heat sink extends into the circulating air duct.

[0022] It is convenient to improve the cooling effect on the outside of the inner cabinet.

[0023] Furthermore, a third solenoid valve is provided at the connection between the first air compression pipeline and the air compression equipment and the inner cabinet; a third solenoid valve is provided at the connection between the second air compression pipeline and the air storage box and the inner cabinet.

[0024] It is convenient to control the precise opening of the first compressed air pipeline and the second compressed air pipeline.

[0025] One of the objectives of the present invention is to provide an automatic temperature and humidity method for an ACU cabinet, the method being used in the above-mentioned system and comprising the following steps:

[0026] S1. Continuously start the fan in the circulating air duct to introduce the outside air into the circulating air duct for circulation;

[0027] S2, detecting first temperature and humidity information in the air storage box and second temperature and humidity information inside the inner cabinet by a temperature and humidity detection module;

[0028] S3. Analyze and determine whether the temperature and humidity of the inner cabinet have reached a preset threshold value based on the second temperature and humidity information. If so, connect the first air compression pipe to the air compression device and the inner cabinet, and start the air compression device to pump air in the inner cabinet into the air storage box, so that the inner cabinet is in a near-vacuum state.

[0029] S4. After the set standing time is met, the first temperature and humidity information is analyzed to determine whether the gas inside the air storage box reaches the preset temperature and humidity input threshold. If so, the second air compression pipe is controlled to connect the inner cabinet and the air storage box to input the air in the air storage box into the inner cabinet.

[0030] Principles and advantages:

[0031] 1. The setting of outer cabinet, inner cabinet and circulating air duct. The circulating air duct can draw in low-temperature air from the outside to form a circulation, thereby cooling the inner cabinet.

[0032] 2. The setting of the temperature and humidity detection module can detect the first temperature and humidity information in the air storage box and the second temperature and humidity information inside the inner cabinet in real time, so as to facilitate the temperature and humidity adjustment of the inner cabinet.

[0033] 2. The setting of the air storage box, air compression component and temperature and humidity adjustment module. When the temperature and humidity adjustment module finds through the detection data of the temperature and humidity detection module that the inner cabinet needs to be temperature and humidity adjusted, the air compression equipment in the air compression component can be controlled to extract the air in the inner cabinet through the first air compression pipe and send it to the air storage box, so that the inner cabinet is in a vacuum state, which can reduce the temperature and humidity in the inner cabinet.

[0034] 3. The arrangement of the second air compression pipe, air storage box, and temperature and humidity adjustment module. Since the electronic components in the inner cabinet continuously generate heat during operation, although there is a circulating air duct to cool the outer surface of the inner cabinet, the electronic components inside the inner cabinet are basically not in contact with the side walls of the inner cabinet, so the cooling effect is still not ideal, and the relative humidity is not easy to achieve, which is not conducive to the normal operation of the electronic components inside the inner cabinet. When the air compression equipment extracts the air in the inner cabinet and sends it to the air storage box, the air pressure in the air storage box increases, and the internal gas temperature will rise. The air storage box is arranged in the circulating air duct, so the circulating air duct will also cool the outside of the air storage box, so that the high-temperature and high-humidity air in the air storage box will condense into water droplets on the inner side wall of the air storage box, thereby achieving the effect of cooling and dehumidifying the air in the air storage box. If the gas inside the air storage box reaches the preset temperature and humidity input threshold, the second air compression pipe is controlled to connect the inner cabinet and the air storage box.

[0035] Since the air storage box is in a high-pressure state and the inner cabinet is in a low-pressure state, the gas in the air storage box can enter the inner cabinet at a higher speed and fill the inner cabinet. At this time, the temperature and humidity of the gas in the air storage box are adjusted, and it can absorb heat from the inside. Combined with the external cooling effect of the circulating air duct, it can achieve automatic and efficient adjustment of temperature and humidity, thereby avoiding excessively high or low temperature and humidity affecting the normal operation of the ACU area control module.

[0036] Furthermore, the method further comprises the following steps:

[0037] S5. Detecting third temperature and humidity information at the connection between the second air compression pipe and the inner cabinet through the temperature and humidity detection module;

[0038] S6. Adjust the opening and closing and the opening degree of the first solenoid valves on the second air compression pipe according to the third temperature and humidity information feedback.

[0039] Since the air storage box is in a high-pressure state and the inner cabinet is in a low-pressure state, the gas in the air storage box can enter the inner cabinet at a higher speed. In addition, a number of openings and inclined baffles are provided on the second air compression pipe. According to the Bernoulli principle, the higher the speed, the lower the pressure. Therefore, the low-temperature and high-humidity gas in the circulating air duct will enter the second air compression pipe from the opening, thereby adjusting the original temperature and humidity in the second air compression pipe. The temperature and humidity fine-tuning module is then used to adjust the opening and closing and opening of the first solenoid valve according to the third temperature and humidity information feedback, so that the temperature and humidity of the gas entering the inner cabinet can be adjusted more accurately, thereby ensuring the stability of the internal environment of the inner cabinet.

[0040] Furthermore, the method further comprises the following steps:

[0041] S7. Adjust the opening and closing of a plurality of second solenoid valves on the second air compression pipe according to the third temperature and humidity information feedback.

[0042] The second compressed air duct is a square-wave U-shaped duct, and a shortcut channel is provided at the U-shaped inflection point of the second compressed air duct. This allows the low-temperature, high-humidity gas in the circulating air duct to be used to cool the gas in the second compressed air duct. If the temperature needs to be adjusted to a lower level, the second solenoid valve is closed, allowing the gas in the second compressed air duct to pass through the interior for a longer time. If the temperature needs to be adjusted to a higher level, the second solenoid valve is opened, allowing the gas in the second compressed air duct to pass through the interior for a shorter time. This allows the temperature of the gas entering the inner cabinet to be adjusted more accurately, thereby ensuring the stability of the internal environment of the inner cabinet.

[0045] Figure 3 The present invention is a logic block diagram of an automatic temperature and humidity adjustment system for an ACU cabinet. DETAILED DESCRIPTION

[0046] The following is further described in detail through specific implementation methods:

[0047] The figure marks in the drawings of the specification include: outer cabinet 1, second air compression pipeline 2, third solenoid valve 3, heat sink 4, inner cabinet 5, air compression equipment 6, air storage box 7, fan 8, air outlet channel 9, second solenoid valve 10, shortcut channel 11, and first solenoid valve 12.

[0048] Example 1

[0049] An automatic temperature and humidity control system for ACU cabinets is basically as follows: Figure 1 、 Figure 2 、 Figure 3 As shown: It includes an outer cabinet 1, an inner cabinet 5 and a control component. The outer cabinet 1 and the inner cabinet 5 are both provided with sealed cabinet doors. The inner cabinet 5 is provided with an ACU area controller, which includes several hot-swappable functional modules.

[0050] The inner cabinet 5 is arranged in the outer cabinet 1, and a circulating air duct and an air compression component are arranged between the inner cabinet 5 and the outer cabinet 1; an air storage box 7 is arranged in the circulating air duct. The circulating air duct wraps the four sides of the inner cabinet 5, namely the top, bottom, left and right sides. A fan 8 is provided at the inlet of the circulating air duct, and an air outlet channel 9 is provided at the outlet of the circulating air duct. The air outlet channel 9 is provided with a number of equally spaced and vertically arranged guide vanes. The guide vanes facilitate the gas in the circulating air duct to flow out from the air outlet channel 9 to balance the internal and external air pressures, and prevent the gas blown in by the fan 8 at the inlet of the circulating air duct from flowing out directly. The inlet of the circulating air duct can be staggered with the air outlet channel 9. In other embodiments, a guide member is provided on the guide vane for adjusting the angle of the guide vane. The guide member adopts a combination of a micro motor and a gear set.

[0051] The outer side of the inner cabinet 5 is surrounded by a heat sink 4 , and the ends of the heat sink 4 extend into the circulating air duct, so that the heat sink 4 can fully contact the low-temperature gas blown into the circulating air duct, thereby achieving a cooling effect.

[0052] The air compression assembly includes an air compression device 6, a first air compression pipeline and a second air compression pipeline 2; the air storage box 7 is provided with a first temperature sensor and a second temperature sensor.

[0053] One end of the first air compression pipeline is connected to the air inlet of the air compression equipment 6, and the other end is connected to the air outlet of the inner cabinet 5; the air outlet of the air compression equipment 6 is connected to the air storage box 7, and one end of the second air compression pipeline 2 is connected to the air storage box 7, and the other end is connected to the air inlet of the inner cabinet 5; a second temperature sensor and a second temperature sensor are placed in the inner cabinet 5; a third solenoid valve 3 is provided at the connection between the first air compression pipeline and the air compression equipment 6 and the inner cabinet 5; a third solenoid valve 3 is provided at the connection between the second air compression pipeline 2 and the air storage box 7 and the inner cabinet 5.

[0054] A third temperature sensor and a third temperature sensor are installed at the connection between the second air compression pipe and the inner cabinet 5. The second air compression pipe 2 is provided with a plurality of openings, each of which is provided with an inclined baffle; and the opening is provided with a first solenoid valve 12 with its opening located in the circulating air duct.

[0055] like Figure 2 As shown, the second compressed air pipeline 2 is a square-wave U-shaped pipeline. A shortcut channel 11 is provided at the U-shaped inflection point of the second compressed air pipeline 2 . A second solenoid valve 10 is provided on the shortcut channel 11 .

[0056] The control component includes:

[0057] Temperature and humidity detection module: used to detect the first temperature and humidity information in the air storage box 7 and the second temperature and humidity information inside the inner cabinet 5;

[0058] Temperature and humidity adjustment module: used to determine whether the inner cabinet 5 reaches the preset temperature and humidity adjustment threshold based on the second temperature and humidity information analysis. If so, the first air compression pipeline is controlled to connect the air compression device 6 and the inner cabinet 5, and the air compression device 6 is started to draw the air in the inner cabinet 5 into the air storage box 7; it is also used to determine whether the internal gas of the air storage box 7 reaches the preset temperature and humidity input threshold through the first temperature and humidity information analysis after the set standing time is met. If so, the second air compression pipeline 2 is controlled to connect the inner cabinet 5 and the air storage box 7.

[0059] Temperature and humidity fine-tuning module: used to adjust the opening and closing and the opening degree of the first solenoid valve 12 according to the third temperature and humidity information feedback. Since the air storage box 7 is in a high-pressure state and the inner cabinet 5 is in a low-pressure state, the gas in the air storage box 7 can enter the inner cabinet 5 at a higher speed. In addition, the second air compression pipe 2 is provided with a number of openings and inclined baffles. According to the Bernoulli principle, the higher the speed, the lower the pressure. Therefore, the low-temperature and high-humidity gas in the circulating air duct will enter the second air compression pipe 2 from the opening, thereby adjusting the original temperature and humidity in the second air compression pipe 2. Then, the temperature and humidity fine-tuning module is used to adjust the opening and closing and the opening degree of the first solenoid valve 12 according to the third temperature and humidity information feedback. It is possible to more accurately adjust the temperature and humidity of the gas entering the inner cabinet 5, thereby ensuring the stability of the internal environment of the inner cabinet 5.

[0060] The temperature and humidity fine-tuning module is also used to adjust the opening and closing of the second solenoid valve 10 according to the third temperature and humidity information feedback. The second air compression pipeline 2 is a square-wave U-shaped pipeline, and a shortcut channel 11 is provided at the U-shaped inflection point of the second air compression pipeline 2. It is convenient to use the low-temperature and high-humidity gas in the circulating air duct to cool the gas in the second air compression pipeline 2. If the temperature needs to be adjusted to a lower level, the second solenoid valve 10 is closed to make the gas in the second air compression pipeline 2 pass through the interior for a longer time. If the temperature needs to be adjusted to a higher level, the second solenoid valve 10 is opened to make the gas in the second air compression pipeline 2 pass through the interior for a shorter time. The temperature of the gas introduced into the inner cabinet 5 can be adjusted more accurately, thereby ensuring the stability of the internal environment of the inner cabinet 5.

[0061] A method for automatically adjusting temperature and humidity of an ACU cabinet comprises the following steps:

[0062] S1, continuously start the fan 8 in the circulating air duct to introduce the outside air into the circulating air duct for circulation;

[0063] S2, detecting first temperature and humidity information in the air storage box 7 and second temperature and humidity information inside the inner cabinet 5 by the temperature and humidity detection module;

[0064] S3. Analyze and determine whether the temperature and humidity of the inner cabinet 5 have reached a preset threshold value based on the second temperature and humidity information. If so, control the first air compression pipeline to connect the air compression device 6 and the inner cabinet 5, and start the air compression device 6 to pump the air in the inner cabinet 5 into the air storage box 7, so that the inner cabinet 5 is in a near-vacuum state.

[0065] S4. After the set standing time is met, the first temperature and humidity information is analyzed to determine whether the gas inside the air storage box 7 reaches the preset temperature and humidity input threshold. If so, the second air compression pipe 2 is controlled to connect the inner cabinet 5 and the air storage box 7, and the air in the air storage box 7 is input into the inner cabinet 5.

[0066] S5, detecting third temperature and humidity information at the connection between the second air compression pipe and the inner cabinet 5 by the temperature and humidity detection module;

[0067] S6. Adjust the opening and closing and the opening degree of the first electromagnetic valves 12 on the second air compression pipe according to the third temperature and humidity information feedback.

[0068] S7. Adjust the opening and closing of the second solenoid valves 10 on the second air compression pipe according to the third temperature and humidity information feedback.

[0069] Example 2

[0070] The difference between Example 2 and Example 1 is that the automatic temperature and humidity adjustment system for the ACU cabinet specifically also includes a pipe gallery maintenance work terminal and a server, and the server is set in the control center. The ACU area controller includes a hot-swappable Bluetooth module and a communication module for wired communication with the control center. The pipe gallery maintenance work terminal is provided with a GPS module and a Bluetooth module. Since there are various engineering pipelines such as electricity, communication, gas, heating, water supply and drainage in the city's underground pipe gallery, there are multiple ACU area controllers at the same location in the city's underground pipe gallery. When the pipe gallery maintenance work terminal enters the city's underground pipe gallery, the Bluetooth module of the nearest ACU area controller can be paired with the pipe gallery maintenance work terminal, and positioning in the city's underground pipe gallery can be achieved through Bluetooth positioning technology, as well as navigation data, alarm notification data, etc. transmitted to the pipe gallery maintenance work terminal through Bluetooth technology. The server includes:

[0071] Temperature and humidity fault monitoring module: used to receive the first temperature and humidity information of the first temperature sensor and the first humidity sensor, the second temperature and humidity information of the second temperature sensor and the second humidity sensor, and the third temperature and humidity information of the third temperature sensor and the third humidity sensor, and perform numerical monitoring of the first temperature and humidity information, the second temperature and humidity information and the third temperature and humidity information, analyze and determine whether the first temperature and humidity information, the second temperature and humidity information or the third temperature and humidity information reaches the alarm temperature and humidity threshold, and determine whether the time to reach the alarm temperature and humidity threshold exceeds the alarm time threshold. If the alarm temperature and humidity threshold is reached and exceeds the alarm time threshold, an alarm message is generated, and the alarm message includes the number information of the ACU area controller.

[0072] Map management module: used to record the distribution map of each ACU area controller in the city's underground pipeline corridor;

[0073] Path planning module: used to obtain the geographic location information of the ACU area controller from the distribution map according to the number information, and perform real-time path planning based on the geographic location information and the Bluetooth positioning of the corridor maintenance work terminal, and send the real-time planned real-time path to the corridor maintenance work terminal.

[0074] Distance measurement module: used to calculate the distance between the ACU area controller and the tunnel maintenance work terminal based on Bluetooth positioning information and the geographical location information of the ACU area controller;

[0075] The prompt module is used to generate a power control instruction to control the output power of fan 8 to increase step by step with distance, a start-up control instruction to activate the air compressor 6, and an angle adjustment instruction to control the guide vanes to adjust their angles. The closer the distance between the ACU area controller and the tunnel maintenance work terminal, the higher the output power of fan 8. The higher the output power, the better the heat dissipation and ventilation. It also generates noise, which helps maintenance personnel identify the ACU area controller requiring maintenance from multiple ACU area controllers in the same location. It also allows maintenance personnel to determine whether fan 8 is functioning properly, facilitating troubleshooting. The noise generated by the air compressor 6 when it is started serves as a prompt and allows maintenance personnel to determine whether the air compressor 6 is functioning properly, facilitating quick troubleshooting. Controlling the angle adjustment of the guide vanes also generates noise, providing a prompt and allowing maintenance personnel to determine whether the circulating air duct is functioning properly, facilitating quick troubleshooting.

Ordinary technicians in the relevant field are aware of all common technical knowledge in the technical field of the invention before the application date or priority date, can obtain all existing technologies in the field, and have the ability to apply conventional experimental means before that date.
