[0014] As a further improvement of the present application, an optical cable fiber distribution box for an optical communication system, and a method for using the optical cable fiber distribution box comprises the following steps:

[0015] Step 1: The controller uses an infrared distance sensor to monitor whether the box is closed. If the box cover is not closed, the controller does not perform other actions. If the box cover is closed, the controller executes step 2.

[0016] Step 2: The controller starts the humidity sensor and temperature sensor to monitor the initial temperature and humidity in the box. The initial monitored humidity and temperature values ​​are divided into four situations:

[0017] The first situation: when the initially monitored humidity is higher than the threshold and the temperature is lower than the threshold, the controller starts the fan and the heating wire, sprays hot air, and monitors the humidity and temperature in real time. As the heating and dehumidification proceeds, it is divided into three sub-situations. In the first sub-situation, as the heating and dehumidification proceeds, when the real-time humidity is higher than the threshold and the temperature is higher than the threshold, the controller turns off the heating wire and keeps the fan on, and sprays cold air for dehumidification until the real-time humidity is lower than the threshold; the second sub-situation: as the heating and dehumidification proceeds, when the real-time humidity is lower than the threshold and the temperature is lower than the threshold, the controller turns off the fan and the heating wire, and maintains temperature and humidity monitoring after dehumidification is completed; the third sub-situation, as the heating and dehumidification proceeds, when the real-time humidity is lower than the threshold and the temperature is higher than the threshold, the heating wire is turned off and the fan is kept on, and cold air is sprayed for heat dissipation until the temperature is lower than the threshold;

[0018] The second case: when the initially monitored humidity exceeds the threshold and the temperature is higher than the threshold, the controller starts the fan to spray cold air for drying until the real-time humidity and temperature are both lower than the threshold, and then turns off the fan;

[0019] The third case: when the initially monitored humidity is lower than the threshold and the temperature is higher than the threshold, the controller starts the fan to spray and dissipate heat;

[0020] In the fourth case, when the initially monitored humidity and temperature are both lower than the threshold, the controller controls the humidity sensor and the temperature sensor to keep monitoring.

[0021] Beneficial effects:

[0022] (1) The present invention uses a spray assembly including a spray head and a swing mechanism to carry out a wide range of spray dehumidification inside the box. The swing mechanism drives the spray head to swing back and forth and longitudinally at the same time, which has a good spray dehumidification effect on the humid and heavy air located in the equipment gap and at the bottom of the box. In addition, by providing a humidity sensor and a controller, the spray assembly can automatically start dehumidification, reduce manual intervention, and is easy to use.

[0023] (2) The present invention dehumidifies and removes dust from the air entering the vacuum cylinder by providing a dehumidification cylinder, a dust removal cylinder and a heating wire, so that the airflow ejected through the blowing head remains dry and dust-free, thereby improving the blowing effect; in addition, through the cooperation of the heating wire and the temperature sensor, hot air is blown in a low-temperature and high-humidity environment, and cold air is blown in a high-temperature and low-humidity environment, thereby adapting to different temperature and humidity environments and taking into account both the dehumidification efficiency and the safe working temperature of the equipment; in addition, heat dissipation and dust removal operations can also be achieved through blowing, thus achieving functional diversity.

[0024] (3) The present invention realizes directional control of the blowing airflow by providing a photoelectric encoder for monitoring the swing angle of the blowing head and an electromagnetic valve for controlling the airflow interruption of the blowing head, so that the blowing airflow maintains a blowing direction from bottom to top, thereby improving the pushing effect on the wet heavy air, reducing the turbulence in the fiber distribution box, and improving the dehumidification efficiency.

[0043] For details, please refer to Fig.11 The humidity in the fiber distribution box is monitored by the humidity sensor 6. When the monitored humidity value exceeds the set threshold value, the controller 4 starts the fan 10, and the fan 10 draws the external airflow into the suction cylinder 9. The airflow is dusted and dehumidified before entering the suction cylinder 9. The dry airflow entering the suction cylinder 9 is injected into the blowing head 18 through the connecting pipe 24. At the same time, the fan 10 drives the first eccentric disk 16 to rotate through the transmission component 17, and the first eccentric disk 16 drives the swing rod 14 to swing back and forth. The swing rod 14 drives the blowing head 18 thereon to swing back and forth. At the same time, the swing rod 14 drives the first eccentric disk 16 to rotate through the transmission component 17. The swing rod 14 drives the first eccentric disk 16 to rotate back and forth ... The moving shaft 21 drives the rolling gear 22 to roll on the fixed rack 23, and the rolling gear 22 drives the second eccentric disk 20 to rotate through the transmission shaft 21. The second eccentric disk 20 drives the rack plate 19 to make longitudinal reciprocating movements on the upper part of the swing rod 14, and the rack plate 19 drives the blowing head 18 to make longitudinal reciprocating swings, thereby achieving the longitudinal reciprocating swing of the blowing head 18 while making left and right reciprocating swings, so that the sprayed airflow fully covers various positions in the box body 1, has a good spray dehumidification effect, and the airflow generated by the spraying discharges the moisture through the exhaust pipe 8, thereby achieving sufficient spray drying.

[0044] See also Figure 8 The blowing head 18 includes a rotating drum 1801 rotatably connected to the swing rod 14, a nozzle 1802 is connected to the upper part of the rotating drum 1801, and arc-shaped and equidistantly distributed latches are provided at the lower part of the rotating drum 1801, the latches are engaged with the rack plate 19, and a connecting pipe 24 is connected to the rotating drum 1801 and a rotating joint is provided at the connection point.

[0045] Specifically, the second eccentric disk 20 drives the rack plate 19 to move back and forth longitudinally, and the rack plate 19 drives the rotating drum 1801 to swing back and forth through the latch teeth below the rotating drum 1801, thereby realizing the reciprocating swing of the nozzle 1802 and expanding the coverage of the spraying airflow.

[0046] See also Figure 8 The second eccentric disk 20 includes a rotating disk 2001, on which a movable eccentric column 2002 is nested and radially slidably connected.

[0047] See also Figure 8 The rack plate 19 is a horizontal rack plate and a horizontal traction groove 1901 is provided at the outer edge for the movable eccentric column 2002 to pass through.

[0048] Specifically, by turning the knob, the radial screw 2003 is driven to rotate, and the radial screw 2003 drives the movable eccentric column 2002 to move on the turntable 2001, thereby changing the radius of the circular motion of the movable eccentric column 2002, thereby changing the stroke of the longitudinal reciprocating movement of the rack plate 19, thereby changing the reciprocating swing range of the spray head 18, and realizing a change in the coverage range of the spray airflow.

[0049] See also Figure 6 A vertical traction groove 1401 is provided at the lower part of the swing rod 14, and a fixed eccentric column penetrating the vertical traction groove 1401 is provided on the first eccentric disk 16; a clamping frame 1402 for mounting the transmission shaft 21 and the blowing head 18 is provided at the upper part of the swing rod 14.

[0051] Specifically, the guide plate 801 is used to prevent dust from flowing back, and the dust box 27 and the drawer box 28 are used to facilitate dust collection. In addition to dehumidification, the controller 4 periodically starts the fan 10 to perform a spray dust removal operation.

[0052] Second implementation method:

[0053] Figure 2 , Figure 4 , Figure 5 and Fig.12An optical cable fiber distribution box for an optical communication system is shown. Based on the first embodiment, an exhaust cylinder 9 is located above a fan 10 and is equipped with a heating wire 13. A controller 4 includes a control module. The input end of the control module is respectively connected to a humidity monitoring module and a temperature monitoring module. The input end of the humidity monitoring module is connected to a humidity sensor 6. The input end of the temperature monitoring module is connected to a temperature sensor 7 installed on the inner wall of the box 1. The output end of the control module is connected to a dehumidification module. The output end of the dehumidification module is respectively connected to the fan 10 and the heating wire 13.

[0054] Specifically, the temperature inside the box 1 is monitored by the temperature sensor 7. When the temperature inside the box 1 is lower than the threshold and the humidity monitored by the humidity sensor 6 exceeds the threshold, the fan 10 and the heating wire 13 are started by the controller 4 to spray hot air to improve the dehumidification efficiency.

[0055] See also Figure 4 The end of the blowing head 18 is fixedly connected with a rotating shaft extending to the outside of the swing rod 14, and a photoelectric encoder 25 is installed at the end of the rotating shaft. A solenoid valve 26 is installed at the connection point between the connecting pipe 24 and the vacuum cylinder 9. The input end of the control module is also connected with an angle monitoring module and a sealing monitoring module. The input end of the angle monitoring module is connected with the photoelectric encoder 25, and the input end of the sealing monitoring module is connected with an infrared distance sensor 5 installed on the inner wall of the box body 1. The infrared distance sensor 5 is arranged opposite to the lock end of the box cover 2, and the solenoid valve 26 is connected to the output end of the dehumidification module.

[0056] Specifically, the vertical swing angle of the blowing head 18 is monitored in real time through the photoelectric encoder 25. When the blowing head 18 blows from bottom to top, the solenoid valve 26 is opened, and the humid heavy air at the bottom of the box 1 is blown upward by the blowing airflow; when the blowing head 18 swings from top to bottom, the solenoid valve 26 is closed, so that the gas cannot enter the blowing head 18, thereby reducing turbulence and improving the moisture discharge efficiency.

[0057] For details, please refer to Fig.12 , an optical cable fiber distribution box for an optical communication system, and a method for using the same comprises the following steps:

[0058] Step 1: The controller 4 monitors whether the box body 1 is closed through the infrared distance sensor 5. If the box cover 2 is not closed, the controller 4 does not perform other actions. If the box cover 2 is in a closed state, step 2 is executed;

[0059] Step 2: The controller 4 starts the humidity sensor 6 and the temperature sensor 7 to monitor the initial temperature and humidity in the box 1. The initial humidity and temperature values ​​are divided into four situations:

[0060] The first situation: when the initially monitored humidity is higher than the threshold and the temperature is lower than the threshold, the controller 4 starts the fan 10 and the heating wire 13, sprays hot air, and monitors the humidity and temperature in real time. As the heating and dehumidification proceeds, it is divided into three sub-situations. The first sub-situation: as the heating and dehumidification proceeds, when the real-time humidity is higher than the threshold and the temperature is higher than the threshold, the controller 4 turns off the heating wire 13 and keeps the fan 10 on, and sprays cold air for dehumidification until the real-time humidity is lower than the threshold; the second sub-situation: as the heating and dehumidification proceeds, when the real-time humidity is lower than the threshold and the temperature is lower than the threshold, the controller 4 turns off the fan 10 and the heating wire 13, and maintains temperature and humidity monitoring after dehumidification is completed; the third sub-situation: as the heating and dehumidification proceeds, when the real-time humidity is lower than the threshold and the temperature is higher than the threshold, the heating wire 13 is turned off and the fan 10 is kept on, and cold air is sprayed for heat dissipation until the temperature is lower than the threshold;

[0061] The second case: when the initially monitored humidity exceeds the threshold and the temperature is higher than the threshold, the controller 4 starts the fan 10 to spray cold air for drying until the real-time humidity and the temperature are both lower than the threshold, and then turns off the fan 10;

[0062] The third situation: when the initially monitored humidity is lower than the threshold and the temperature is higher than the threshold, the controller 4 starts the fan 10 to spray and dissipate heat;

[0063] In the fourth case, when the initially monitored humidity and temperature are both lower than the threshold, the controller 4 controls the humidity sensor 6 and the temperature sensor 7 to keep monitoring.

[0064] Specifically, by monitoring the temperature and humidity, a balance is found between dehumidification efficiency and temperature control to protect the equipment in the fiber distribution box from working normally during the dehumidification and heat dissipation process.

[0065] It should be noted that the temperature and humidity thresholds are manually set according to the working temperature and humidity range of the equipment in the fiber splitter box, and the control module is also connected to the setting module.

[0066] In view of current practical needs, the above-mentioned implementation mode adopted in this application is not limited to the scope of protection. Various changes made within the knowledge scope of technical personnel in this field without departing from the concept of this application still fall within the scope of protection of the present invention.

In the third sub-case, as the heating and dehumidification proceeds, when the real-time humidity is lower than the threshold and the temperature is higher than the threshold, the heating wire (13) is turned off and the fan (10) is kept on to spray cold air for heat dissipation until the temperature is lower than the threshold. The second case: when the initially monitored humidity exceeds the threshold and the temperature is higher than the threshold, the controller (4) starts the fan (10) to spray cold air for drying until the real-time humidity and the temperature are both lower than the threshold, and then turns off the fan (10); The third situation: when the initially monitored humidity is lower than the threshold and the temperature is higher than the threshold, the controller (4) starts the fan (10) to spray and dissipate heat; In the fourth case, when the initially monitored humidity and temperature are both lower than the threshold, the controller (4) controls the humidity sensor (6) and the temperature sensor (7) to keep monitoring; The end of the spray head (18) is fixedly connected to a rotating shaft extending to the outside of the swing rod (14), a photoelectric encoder (25) is installed at the end of the rotating shaft, a solenoid valve (26) is installed at the connection point between the connecting pipe (24) and the vacuum cylinder (9), the input end of the control module is also connected to an angle monitoring module and a sealing monitoring module, the input end of the angle monitoring module is connected to the photoelectric encoder (25), the input end of the sealing monitoring module is connected to an infrared distance sensor (5) installed on the inner wall of the box body (1), the infrared distance sensor (5) is arranged opposite to the lock end of the box cover (2), and the solenoid valve (26) is connected to the output end of the dehumidification module; The vertical swing angle of the blowing head (18) is monitored in real time by means of a photoelectric encoder (25).
