The air inlet of the air inlet rain cover 11 is provided with a thin mesh steel wire net, flying cotton and the like are intercepted by the cotton blocking net 9, the cotton blocking net 9 is arranged on the inner side of the air inlet of the cabinet 18, insects, flying cotton, cotton and the like are prevented from entering, when the cotton and the like adhere to the cotton blocking net to influence the air inlet quantity, maintenance can be carried out indoors, and safety accidents caused by manual outdoor high-altitude operation maintenance are avoided. The air outlet of the air exhaust rain-proof cover 29 is provided with a dense-mesh steel wire mesh insect prevention, the air inlet rain-proof cover 11 is an air inlet wall hole for preventing rain, and the air exhaust rain-proof cover 29 is an air exhaust wall hole for preventing rain; the air inlet and outlet wall holes of the base station are too large to be opened for safety and theft prevention, so the air inlet rain cover 11 and the air outlet rain cover 29 for the base station are preferably made of PVC pipes with the diameter of 180 mm-200 mm.

The air inlet air door 14, the air outlet air door 28 and the air mixing air door 8 are both composed of an air door motor and a leaf, and after the air inlet air door 14 and the air outlet air door 28 are simultaneously opened, the fan 2 and the air outlet fan 27 are started; the outdoor cold air flows in, the indoor hot air is discharged, and after the fan 2 and the exhaust fan 27 are closed, the air inlet air door 14 and the exhaust air door 28 are closed after delay, so that the cold energy loss of indoor air conditioner refrigeration is prevented, and the outdoor cold air is prevented from entering the indoor space in winter. The fan 2 adopts a centrifugal fan with low noise, high wind pressure and large wind volume, and the large wind volume generated by the fan enables outdoor cold air to be filtered by the air filter 20 and then enter the room for cooling. The exhaust fan 27 adopts an axial flow fan and functions to exhaust indoor hot air to the outside. The small machine room and the mobile base station can also cancel the exhaust fan 27, and the indoor positive pressure is used for extruding the hot air out of the room.

If the outdoor cold source is insufficient to reduce the temperature of the equipment, and the indoor temperature gradually rises to 28 ℃, the controller 25 turns off the fan 2 and the exhaust fan 27, and then turns off the air inlet air door 14 and the exhaust air door 28, so that the air conditioner 19 is started to refrigerate. When the indoor temperature drops to 22 ℃, the air conditioner 19 is closed, and the air inlet air door 14 and the air outlet air door 28 are opened, and then the fan 2 and the air outlet fan 27 are started.

When the indoor temperature rises to 28 ℃, if the air conditioner fails, the air conditioner 19 is turned off, the fan system is forcefully started for ventilation and cooling when the indoor temperature continues to rise to 45 ℃, and meanwhile, an alarm of air conditioner failure and superhigh temperature is sent to the upper computer. When the indoor humidity measured by the indoor temperature and humidity sensor 30 reaches 60%, the fan system is not started, and the air conditioner 19 is started for dehumidification. When the outdoor temperature and humidity sensor 12 detects that the outdoor temperature is more than 25 ℃ or the humidity is more than 80%, the fan is not started.

The upper computer carries out remote automatic management of remote measurement, remote signaling and remote control on the utility model through a network management system.

When the outdoor cold air is lower than the dew point temperature (assuming 14 ℃), the air mixing door 8 is opened, the outdoor supercooled air and the indoor hot air are mixed in the filter cavity and enter the room through the clean cavity, condensation is avoided, and when the air mixing temperature sensor 4 detects that the air entering the room reaches 20 ℃, the air mixing door 8 is closed.

When the indoor humidity is lower than 30%, a humidifying system is started to humidify the indoor, so that the communication safety is prevented from being damaged by static electricity (the indoor humidifying system is suitable for civil air conditioners).

When the humidity of the machine room is greater than or equal to 60%, the dehumidifying interface can be externally connected with a dehumidifier to start dehumidification. When the humidity drops to 50%, the dehumidifier is turned off.

The temperature of the base station/machine room is too low in winter in the north, and the heater interface can be externally connected with a heater to heat the room when the temperature of the machine room/base station is lower than 0 ℃.
