Description
Technical Field
[0001] The present application relates to the technical field of communication equipment, and in particular to a communication cabinet. Background Art
[0002] With the rapid development of science and technology, the communication volume has increased rapidly, and the workload of communication equipment has increased. Communication cabinets generate a lot of heat during operation. In order to cope with the rising temperature in the cabinet, the refrigeration system in the cabinet runs for a long time, and its energy consumption accounts for up to 40% of the total energy consumption.
[0003] In the prior art, in order to reduce the energy consumption of the communication cabinet, when the temperature inside the communication cabinet is too high, the cabinet door is opened to connect the space inside the communication cabinet with the space outside the communication cabinet, so that the air inside the cabinet and the air outside the cabinet can exchange heat. In this way, the temperature inside the communication cabinet can be reduced.
[0004] However, in the heat dissipation process of the communication cabinet in the prior art, there is a potential safety hazard that the cabinet door may be opened rashly to cause harm to people around the cabinet door. Summary of the invention
[0005] The present application provides a communication cabinet to at least solve the potential safety hazard of causing harm to people around the cabinet door when the cabinet door is opened during the heat dissipation process of the communication cabinet.

DETAILED DESCRIPTION
[0023] The communication cabinet provided in the embodiment of the present application is described in detail below with reference to the accompanying drawings.
[0024] The term "and / or" in this article is merely a description of the association relationship of associated objects, indicating that three relationships may exist. For example, A and / or B can mean: A exists alone, A and B exist at the same time, and B exists alone.
[0025] The terms "first" and "second" and the like in the specification and drawings of this application are used to distinguish different objects, or to distinguish different processing of the same object, rather than to describe a specific order of objects.
[0026] In addition, the terms "including" and "having" and any variations thereof mentioned in the description of the present application are intended to cover non-exclusive inclusions. For example, a process, method, system, product or device comprising a series of steps or units is not limited to the listed steps or units, but may optionally include other steps or units that are not listed, or may optionally include other steps or units that are inherent to these processes, methods, products or devices.
[0027] It should be noted that, in the embodiments of the present application, words such as "exemplarily" or "for example" are used to indicate examples, illustrations or descriptions. Any embodiment or design described as "exemplarily" or "for example" in the embodiments of the present application should not be interpreted as being more preferred or more advantageous than other embodiments or designs. Specifically, the use of words such as "exemplarily" or "for example" is intended to present related concepts in a specific way.
[0028] In the description of the present application, unless otherwise specified, “plurality” means two or more.
[0029] With the rapid development of science and technology, the communication field has shown a trend of rapid growth in communication volume. This growth has caused communication equipment to face high-intensity workloads. Many communication equipment has been in high-load operation for a long time to process massive amounts of data. Communication equipment generates a lot of heat during operation, causing the temperature inside the cabinet to continue to rise. In order to maintain a suitable temperature environment in the cabinet and ensure the normal operation of communication equipment, the refrigeration system in the cabinet has to run continuously for a long time, which leads to a significant increase in the energy consumption of the refrigeration system. In addition, the temperature inside the cabinet is affected by the external temperature in addition to the heat dissipation of the internal equipment. When the temperature outside the cabinet is high, the heat dissipation energy consumption of the cabinet is high, and when the temperature outside the cabinet is low, the heat dissipation energy consumption of the cabinet is low.
[0030] In the related art, in order to reduce the energy consumption of the communication cabinet, when the temperature inside the communication cabinet is too high, the cabinet door is opened to connect the space inside the communication cabinet with the space outside the communication cabinet, so that the hot air inside the cabinet flows out of the cabinet. In this way, energy consumption can be reduced by dissipating heat through the natural environment.
[0031] However, during this process, the cabinet door needs to be opened, which poses a safety hazard.
[0032] Safety hazards include personnel hazards and equipment hazards outside the communication cabinet.
[0033] Specifically, when the cabinet door is opened rashly, it may cause collision injuries to people around it. Or, after the cabinet door is opened, people around the cabinet may touch the internal equipment without knowing it, which may cause safety problems such as electric shock.
[0034] At the same time, opening the cabinet door will expose the communication equipment inside to the air, and people outside the cabinet may touch the communication equipment out of curiosity, which may cause the connection of the communication equipment to loosen, parameters to change, or internal components to be damaged.
[0035] like Figure 1 As shown, in order to solve the above problems, the present application provides a communication cabinet 100, which includes a cabinet body 1 provided with a cabinet door 2, a driving device 3, a first sensor 10 and a controller 4.
[0036] The cabinet door 2 is connected to the cabinet body 1. The driving device 3 is drivingly connected to the cabinet door 2 and drives the cabinet door 2 to switch between an open state and a closed state.
[0037] The cabinet 1 is used to accommodate communication equipment.
[0038] Exemplarily, the driving device 3 includes, but is not limited to: an electric driving device, a pneumatic driving device, a hydraulic driving device, a mechanical spring driving device, and an electromagnetic driving device.
[0039] The first sensor 10 is disposed outside the cabinet 1 and connected to the cabinet 1 , and is used to detect whether there is a person within a preset range of the cabinet 1 .
[0040] Exemplarily, the first sensor 10 includes, but is not limited to: an infrared sensor, an ultrasonic sensor, and a photoelectric sensor.
[0041] The controller 4 is connected to the driving device 3 and the first sensor 10. The controller 4 is used to control the driving device 3 to drive the cabinet door 2 to switch from a closed state to an open state under a first preset condition. The first preset condition includes: no one is within a preset range of the cabinet 1.
[0042] When the cabinet door 2 needs to be opened, the first sensor 10 is used to detect whether there is anyone within the preset range of the cabinet 1. When there is no one within the preset range of the cabinet 1, the first preset condition is met, and the controller 4 controls the cabinet door 2 to switch from the closed state to the open state. When the cabinet door 2 needs to be opened, the first sensor 10 is used to detect whether there is someone within the preset range of the cabinet 1. If the first preset condition is not met, the cabinet door 2 will not be opened, so the cabinet door 2 will not be suddenly opened when someone approaches or works nearby, causing harm to the person.
[0043] Therefore, when there are people around the communication cabinet 100, the cabinet door 2 will not be opened. In this way, there is no situation where people around the communication cabinet 100 are injured, and there is no risk of electric shock caused by contact with communication equipment by people around.
[0044] Meanwhile, when there are people around the communication cabinet 100, the cabinet door 2 will not be opened. In this way, there is no situation where people outside the cabinet 1 touch the communication equipment inside the cabinet, thereby protecting the communication equipment and reducing the risk of damage to the communication equipment.
[0045] In a possible implementation, the preset range may be a value greater than or equal to 2 meters.
[0046] Exemplarily, the preset range may be 2 meters, 3 meters, 4 meters, 5 meters, 6 meters, 8 meters, 10 meters or 15 meters.
[0047] The embodiments of the present application are described in detail below in conjunction with the accompanying drawings, and before describing the embodiments of the present application in detail, the application scenarios of the embodiments of the present application are first described.
[0048] The communication cabinet 100 provided in the present application is used in any scenario where there is a need for transmitting and computing data, such as a data center, a computer room, a network center, and outdoors.
[0049] In a possible implementation manner, a plurality of first sensors 10 may be provided, and the plurality of first sensors 10 are provided on a plurality of outer wall surfaces of the cabinet 1 .
[0050] The first sensor 10 can detect an area on a side of the first sensor 10 away from the cabinet 1. Arranging a plurality of first sensors 10 around the communication cabinet 100 can reduce detection blind areas.
[0051] Providing a plurality of first sensors 10 can also reduce the probability of misjudgment and improve the reliability of the system.
[0052] In a possible implementation, the cabinet door 2 is provided with ventilation holes 21. The ventilation holes 21 can promote air exchange inside and outside the cabinet, so that the heat generated by the equipment in the cabinet can be more dissipated to the external environment. In this way, the stability of the equipment is maintained and the service life of the equipment is extended. The ventilation holes 21 are convenient for observing the status of the equipment without opening the cabinet door 2, which is convenient for inspection and maintenance.
[0053] In a possible implementation, multiple cabinet doors 2 may be provided. When multiple cabinet doors 2 are opened, a larger ventilation area can be provided, thereby allowing a larger air flow to pass through the cabinet, thereby enhancing the heat dissipation effect, and allowing the communication equipment to operate in a suitable temperature environment.
[0054] When it is necessary to maintain, repair or replace the equipment in the cabinet, the multiple cabinet doors 2 can provide a more spacious operating space for easy operation.
[0055] Exemplarily, two cabinet doors 2 may be provided. The two cabinet doors 2 may be located on one side wall of the cabinet 1 , the two cabinet doors 2 may be located on two intersecting side walls of the cabinet 1 , or the two cabinet doors 2 may be located on two opposite side walls of the cabinet 1 .
[0056] Exemplarily, three cabinet doors 2 may be provided.
[0057] Exemplarily, four cabinet doors 2 may be provided. The four cabinet doors 2 may be respectively located on four side walls of the cabinet body 1 connected in sequence.
[0058] In a possible implementation manner, the cabinet door 2 is hinged to the cabinet body 1 , and the cabinet door 2 opens outwards, and the cabinet door 2 does not conflict with the equipment and structure in the cabinet body 1 when opening outwards.
[0059] The cabinet door 2 in the present application can be a metal cabinet door, a glass cabinet door, a rolling door, etc.
[0060] In a possible implementation, Figure 2 The communication cabinet 100 further includes a protective door 9. The protective door 9 is located on a side of the cabinet door 2 close to the cabinet body 1, the protective door 9 is connected to the cabinet body 1, and a ventilation gap is provided on the protective door 9.
[0061] The protective door 9 can reduce the entry of debris into the cabinet 1 while achieving ventilation, thereby improving the cleanliness of the cabinet 1.
[0062] The protective door 9 can also prevent unauthorized personnel, animals, etc. from contacting the equipment in the cabinet, reduce damage to the equipment in the cabinet 1, and also reduce safety accidents such as electric shock, thereby ensuring the normal operation of the equipment.
[0063] The protective door 9 is located on a side of the cabinet door 2 close to the cabinet body 1 . When the cabinet door 2 is opened to the outside of the cabinet body 1 , the protective door 9 will not hinder the cabinet door 2 , thus facilitating the opening of the cabinet door 2 .
[0064] The number and location of the protective doors 9 can be set corresponding to the number and location of the cabinet doors 2 .
[0065] The ventilation gap can be set accordingly according to the size of foreign objects that need to be prevented from entering the cabinet 1.
[0066] In a possible implementation, when the cabinet door 2 is a rolling door, the protective door 9 can be arranged on the side of the cabinet door 2 facing away from the cabinet body 1. In this case, the protective door 9 will not hinder the cabinet door 2 from opening or closing.
[0067] In one possible implementation, see Figure 1 The communication cabinet 100 further includes a temperature detector 5. The temperature detector 5 is connected to the controller 4, and is used to detect a first temperature value inside the cabinet 1 and a second temperature value outside the cabinet 1. The first preset condition also includes that the first temperature value is greater than the second temperature value.
[0068] The temperature value inside and outside the cabinet 1 is monitored in real time by the temperature detector 5, and fed back to the controller 4. When the preset condition that the first temperature value is greater than the second temperature value is met, it indicates that the air temperature outside the cabinet 1 is lower than the air temperature inside the cabinet 1, and the requirement of exchanging heat inside the cabinet 1 to outside the cabinet 1 is met.
[0069] The controller 4 controls the driving device 3 to open the cabinet door 2, so as to facilitate the heat inside the cabinet 1 to be exchanged to the outside of the cabinet 1, thereby preventing heat accumulation.
[0070] When the cabinet door 2 is opened, cold air outside the cabinet body 1 can naturally flow into the interior of the cabinet, thereby accelerating the heat exchange rate and thus accelerating the speed at which the temperature in the cabinet body 1 decreases.
[0071] In this way, the heat dissipation demand of the cabinet can be met by relying on natural ventilation. At this time, heat is dissipated by opening the cabinet door 2, and there is no need to run the refrigeration system, thereby reducing the energy consumption of the communication cabinet 100, achieving energy conservation and emission reduction, and reducing the operating cost of the communication cabinet 100.
[0072] In one possible implementation, see Figure 1 The temperature detector 5 includes a first temperature detector 51 and a second temperature detector 52 .
[0073] The first temperature detector 51 is located in the cabinet 1 and connected to the controller 4 . The first temperature detector 51 outputs a first temperature value.
[0074] The first temperature detector 51 is located in the cabinet 1 to collect temperature value change data in the cabinet 1 .
[0075] The connection mode between the first temperature detector 51 and the controller 4 includes, but is not limited to, wired connection, wireless connection, and a combination of wired connection and wireless connection. The wired connection includes, but is not limited to, analog signal connection and digital signal connection. The wireless connection includes, but is not limited to, Bluetooth connection, Wi-Fi connection, and ZigBee connection. ZigBee technology is a wireless communication technology used in short distances and low rates. ZigBee is also known as "HomeRF Lite" and "FireFly" technology.
[0076] The second temperature detector 52 is located outside the cabinet 1 and connected to the controller 4 . The second temperature detector 52 outputs a second temperature value.
[0077] The second temperature detector 52 is located outside the cabinet 1, so as to collect the temperature value outside the cabinet 1. The second temperature detector 52 can be connected to the cabinet 1, or can be located at other positions not connected to the cabinet 1.
[0078] The connection method between the second temperature detector 52 and the controller 4 includes, but is not limited to, wired connection, wireless connection, or a combination of wired connection and wireless connection. The wired connection includes, but is not limited to, analog signal connection and digital signal connection. The wireless connection includes, but is not limited to, Bluetooth connection, Wi-Fi connection, and ZigBee connection.
[0079] The first temperature detector 51 and the second temperature detector 52 include, but are not limited to: a thermistor temperature detector, a thermocouple temperature detector, an integrated temperature sensor, and an infrared temperature sensor.
[0080] In a possible implementation, the controller 4 is used to control the drive device 3 to drive the cabinet door 2 to switch from a closed state to an open state when the first preset condition and the third preset condition are met. The third preset condition includes: the first temperature value is greater than the heat dissipation temperature value.
[0081] It should be noted that the first preset condition here may include that there is no one in the preset range of the cabinet and the first temperature value is greater than the second temperature value. The first preset condition appearing in the following description can be understood in this way.
[0082] When the first temperature value is higher than the heat dissipation temperature value, and the first temperature value is greater than the second temperature value, the controller 4 controls the driving device 3 to drive the cabinet door 2 to switch from the closed state to the open state. At this time, the cabinet door 2 can be opened to dissipate heat using the relatively low-temperature air outside the cabinet body 1. Using natural low-temperature air for heat dissipation can reduce energy consumption, thereby reducing the energy consumption of the communication cabinet 100, achieving energy conservation and emission reduction, and reducing the operating cost of the communication cabinet 100.
[0083] The heat dissipation temperature value can be understood as a critical temperature, which is greater than or equal to the appropriate temperature value required for the normal operation of the communication device. That is, the first temperature value is higher than the heat dissipation temperature, indicating that the communication device cannot be maintained within the appropriate operating temperature range at this time.
[0084] The heat dissipation temperature value can be any value less than 30°C.
[0085] Exemplarily, the heat dissipation temperature value may be any one of 30°C, 29°C, 28°C, 27°C, 26°C, 25°C, 25°C, 20°C or 15°C.
[0086] It should be noted that there is no particular order for satisfying the first preset condition and satisfying the third preset condition.
[0087] In one possible implementation, see Figure 1 .exist Figure 1 In the embodiment, the environmental parameter detector 6 and the second temperature sensor 52 are arranged together.
[0088] The communication cabinet 100 further includes an environmental parameter detector 6, which is located outside the cabinet 1 and connected to the controller 4. The environmental parameter detector 6 is used to detect environmental parameters outside the cabinet 1. The controller 4 is used to control the drive device 3 to drive the cabinet door 2 to switch from a closed state to an open state when the first preset condition and the second preset condition are met. The second preset condition includes: the environmental parameters outside the cabinet 1 meet the preset parameters.
[0089] The environmental parameter detector 6 detects the environment outside the cabinet 1. When the cabinet door 2 needs to be switched from a closed state to an open state, the environment outside the cabinet 1 is detected by the environmental parameter detector 6. When the environment outside the cabinet 1 reaches an environment where the cabinet door 2 can be opened, the controller 4 controls the driving device 3 to drive the cabinet door 2 to switch from a closed state to an open state.
[0090] The environment outside the cabinet 1 is detected by the environmental parameter detector 6, and when the environmental parameters outside the cabinet 1 meet the preset parameters, the control cabinet door 2 is opened, which can prevent the communication equipment from being exposed to an adverse environment, thereby extending the service life of the communication equipment and reducing the cost of repairing and replacing the equipment.
[0091] The preset parameters include but are not limited to: humidity, wind speed, dust volume, electromagnetic interference intensity, electromagnetic compatibility, air pressure, vibration intensity, static electricity, and air quality.
[0092] The environmental parameter detector 6 can be connected to the outside of the cabinet 1. The environmental parameter detector 6 can be arranged outside the cabinet 1 and not connected to the cabinet 1.
[0093] In summary, the controller 4 controls the driving device 3 to drive the cabinet door 2 to switch from the closed state to the open state, which requires that the first temperature value inside the cabinet 1 is greater than the second temperature value, and the environmental parameters outside the cabinet 1 meet the preset parameters.
[0094] In a possible implementation, the environmental parameter detector 6 includes a wind speed sensor. The wind speed sensor is used to detect the environmental wind speed outside the cabinet 1. The environmental parameter outside the cabinet 1 meets the preset parameter including: the environmental wind speed outside the cabinet 1 is lower than the preset wind speed.
[0095] A large number of sophisticated communication devices are usually placed inside the communication cabinet 100, and these devices have high requirements for the environment. When the wind speed is too high, it will affect the electrical connection, such as loosening the electrical connection, thereby damaging the equipment. The wind speed sensor detects the ambient wind speed, and only opens the cabinet door 2 when the wind speed is lower than the preset wind speed, which can reduce the damage to the communication equipment in the cabinet caused by strong wind.
[0096] The wind speed sensor can detect the wind speed outside the cabinet 1 in real time, and can provide accurate wind speed data to the controller 4, so that the controller 4 can execute other steps.
[0097] Reasonable wind speed can improve the efficiency of heat transfer generated by the communication equipment in the cabinet 1 and reduce local overheating.
[0098] Exemplarily, the wind speed sensor includes but is not limited to a three-cup wind speed sensor, an ultrasonic wind speed sensor, and a hot wire wind speed sensor.
[0099] The preset wind speed may be any one below 5 m / s.
[0100] Exemplarily, the preset wind speed may be any one of 1 m / s, 1.5 m / s, 2 m / s, 2.5 m / s, 3 m / s, 3.5 m / s, 4 m / s, 4.5 m / s or 5 m / s.
[0101] The connection mode between the wind speed sensor and the controller 4 includes, but is not limited to, wired connection, wireless connection, or a combination of wired connection and wireless connection. The wired connection includes, but is not limited to, analog signal connection and digital signal connection.
[0102] In a possible implementation, the environmental parameter detector 6 further includes a particle sensor. The particle sensor is used to detect the particle content outside the cabinet 1. The environmental parameter outside the cabinet 1 meets the preset parameter including: the particle content outside the cabinet 1 is lower than the preset particle content.
[0103] When the communication equipment inside the communication cabinet 100 is located in the environment outside the cabinet 1, the air may contain a large amount of dust particles. Such dust may accumulate on components such as circuit boards, heat sinks, and fans of the communication equipment. On circuit boards, dust accumulation may cause short circuits or interfere with signal transmission between electronic components; on heat sinks, dust accumulation may reduce heat dissipation efficiency and cause the temperature of the equipment to rise; on fans, dust accumulation may affect the rotation balance of the fans, thereby affecting heat dissipation and air circulation.
[0104] The particle content is detected by the particle sensor. Only when the particle content in the air is lower than the preset particle content, the cabinet door 2 is opened, which can reduce the damage to the equipment caused by the entry of particles. This can reduce the damage to the communication equipment, reduce electrical failures, shorten the maintenance cycle, and increase the service life. It can also ensure the quality of communication services.
[0105] Exemplarily, the particle sensor includes, but is not limited to: an optical particle sensor, a gravimetric particle sensor, and a piezoelectric particle sensor.
[0106] Particulate matter includes but is not limited to PM10 (particles with an aerodynamic equivalent diameter of 10 microns or less), PM2.5 (particles with an aerodynamic equivalent diameter of 2.5 microns or less), hydrogen chloride (HCl), sulfur dioxide (SO 2 ), nitrogen oxides, mercury, lead and dioxins, etc.
[0107] The preset particulate matter content may be any one of less than 100 μg / cubic meter.
[0108] Exemplarily, the preset particulate matter content may be any one of 5 μg / m3, 10 μg / m3, 20 μg / m3, 30 μg / m3, 40 μg / m3, 50 μg / m3, 60 μg / m3, 80 μg / m3 or 100 μg / m3.
[0109] The connection method between the particle sensor and the controller 4 includes, but is not limited to, wired connection, wireless connection, or a combination of wired connection and wireless connection. The wired connection includes, but is not limited to, analog signal connection and digital signal connection.
[0110] In a possible implementation, the environmental parameter detector 6 further includes a humidity sensor. The humidity sensor is used to detect the air humidity outside the cabinet 1. The environmental parameter outside the cabinet 1 meets the preset parameter including: the air humidity outside the cabinet 1 is lower than the preset air humidity.
[0111] In a high humidity environment, moisture may condense on the surface of communication equipment. Specifically, when the air humidity reaches saturation, water vapor may form water droplets on the circuit boards, chips and other components of the communication equipment. This situation will cause a short circuit, which in turn will damage the communication equipment. At the same time, high humidity will also accelerate the corrosion of metal parts, affecting the service life of the equipment.
[0112] In this way, the communication equipment inside the communication cabinet 100 needs to control the humidity when working. The humidity sensor detects the air humidity outside the cabinet 1, and only allows the cabinet door 2 to be opened when the humidity is lower than the preset value, which can reduce the damage to the communication equipment caused by the high humidity environment. It can also reduce the damage to the communication equipment, reduce electrical failures, shorten the maintenance cycle, and increase the service life, thereby ensuring the quality of communication services.
[0113] Exemplarily, the humidity sensor includes, but is not limited to: a capacitive humidity sensor, a resistive humidity sensor, an inductive humidity sensor, and an infrared humidity sensor.
[0114] The preset air humidity may be any one lower than 60%. It should be noted that the air humidity here refers to relative humidity, which indicates the ratio of the water vapor content in the air to the maximum water vapor content that the air can maintain at the same temperature.
[0115] Exemplarily, the preset air humidity may be any one of 60%, 55%, 50%, 45%, 40%, 35%, 30%, 25%, 20%, 15% or 10%.
[0116] When different communication devices in the communication cabinet 100 have different requirements on humidity, the preset air humidity can be set correspondingly according to different communication devices.
[0117] The connection mode between the humidity sensor and the controller 4 includes, but is not limited to, wired connection, wireless connection, or a combination of wired connection and wireless connection. The wired connection includes, but is not limited to, analog signal connection and digital signal connection.
[0118] In one possible implementation, see Figure 1 The communication cabinet 100 further includes a refrigeration device 7. The refrigeration device 7 is located in the cabinet 1 and is connected to the controller 4. The controller 4 is used to control the refrigeration device 7 to operate when the first preset condition is met and the second preset condition is not met.
[0119] When the first preset condition is met, the second preset condition is given priority. When the second preset condition is met, the cabinet door 2 is opened to dissipate heat, utilize the natural environment to dissipate heat, save energy, and reduce the energy consumption of the communication cabinet 100.
[0120] When the first preset condition is met, the external environment of the cabinet 1 is not ideal and does not meet the second preset condition. The temperature parameters in the cabinet are adjusted by the refrigeration device 7 so that the communication equipment can work in a suitable environment, reduce the probability of equipment failure, and extend the service life of the equipment.
[0121] The refrigeration device 7 includes, but is not limited to: an air conditioning system, a semiconductor refrigeration device, an evaporative cooling refrigeration device, an air cooling system, and a liquid cooling system.
[0122] In a possible implementation, the communication cabinet 100 further includes an alarm device 8. The alarm device 8 is connected to the controller 4. The controller 4 is used to control the drive device 3 to drive the cabinet door 2 to switch from a closed state to an open state and control the alarm device 8 to alarm when a fourth preset condition is met. The fourth preset condition includes: the first temperature value is greater than the safety temperature value, wherein the safety temperature value is greater than the heat dissipation temperature value.
[0123] The fourth preset condition is that the first temperature value is greater than the safety temperature value. The safety temperature is the temperature threshold at which the device is heated and damaged. When the first temperature value is greater than the safety temperature value, the controller 4 controls the drive device 3 to drive the cabinet door 2 to switch from the closed state to the open state, and controls the alarm device 8 to alarm.
[0124] By setting the fourth preset condition, an alarm can be issued and measures can be taken before the temperature approaches the critical temperature of equipment damage. Specifically, the controller 4 controls the drive device 3 to open the cabinet door 2 to dissipate heat, thereby reducing the risk of equipment damage due to overheating and extending the service life of the equipment.
[0125] Setting the fourth preset condition can also reduce the risk of fire and improve the safety of the cabinet and the surrounding environment.
[0126] By setting the alarm device 8, when the first temperature reaches the safe temperature, the equipment is in a dangerous state and sends out an alarm signal to the surroundings, thereby reducing the chances of surrounding organisms approaching, thereby reducing the risk of subsequent safety accidents.
[0127] Furthermore, the alarm device 8 can be provided to remind maintenance personnel to inspect and repair the equipment, thereby reducing the risk of equipment damage.
[0128] Exemplarily, the alarm device 8 may be a sound source alarm device and / or a light source alarm device.
[0129] In a possible implementation, the sound source alarm device 8 includes a speaker, and the light source alarm device 8 includes a warning light. The alarm device 8 also includes a power supply and a communication transmission module, and the communication transmission module is used to transmit the first temperature to a user display interface. The user display interface can be a terminal device such as a mobile phone, a computer, and a communication center.
[0130] The safety temperature may be any temperature value between 50° C. and 70° C. The safety temperature may be adjusted accordingly according to the heat resistance of the communication equipment.
[0131] Illustratively, the safe temperature may be any one of 50°C, 55°C, 60°C, 65°C or 70°C.
[0132] The connection mode between the alarm device 8 and the controller 4 includes, but is not limited to, wired connection, wireless connection, or a combination of wired connection and wireless connection. The wired connection includes, but is not limited to, analog signal connection and digital signal connection.
