the power supply unit is used for starting a motor, the short shafts at the two ends of the motor drive the fan I or the fan II to rotate, the adjusting unit is used for adjusting the output power of the motor, the intercepting unit is used for intercepting indoor dust, the calculating unit is used for calculating the interval between two times of measurement temperature and humidity, and the prompting unit is used for sending information early warning to an operator when the indoor dust reaches a set condition.
7. The remote control system of an air-suspending centrifugal fan as claimed in claim 6, wherein: the control system comprises the following specific operation steps:
s1: placing the base indoors, wherein the first port (3) faces outdoors, the second port (4) faces indoors, and the inclination directions of the fan blades of the first fan and the second fan are opposite;
s2: starting a temperature sensor and a humidity sensor to measure the current indoor temperature and humidity, starting a motor when the detected temperature is higher than a set value, driving a first fan to rotate by a short shaft at one end of a rotating motor, and extracting indoor air through a second inlet (4) and discharging the air to the outside through a first inlet (3);
s3: when the detected humidity is higher than a set value, a motor is started, a short shaft at the other end of the motor is rotated, a rotating shaft is driven to rotate through a belt, a fan II is driven to rotate through the rotating shaft, outside air is extracted through a port I (3) and is discharged into a room through a port II (4), and indoor air humidity is increased and is dried because water is accumulated in the room or water on the ground is not volatilized in time due to mopping, so that goods are prevented from being influenced;
s4: moving the screen until the screen completely covers the second opening (4) in the process of working the first fan;
s5: when the fan stops working, scanning the attachment condition of dust and impurities on meshes of the screen;
s6: the method comprises the steps of calculating the number of blocked meshes of a screen, when the number of blocked meshes is less than 20% of the number of middle meshes, proving that the amount of dust in a room in the current time period is less, when the number of blocked meshes is 20% -40% of the number of middle meshes, proving that the amount of dust in the room in the current time period is increased and the cleaning is needed, sending information to prompt an operator by a prompt unit, when the number of blocked meshes is more than 40% of the number of middle meshes, proving that the amount of dust in the room in the current time period is increased violently and the goods are damaged, sending information to prompt the operator to examine the goods immediately by the prompt unit, and setting the content of a sent information code by the operator.
8. The remote control system of an air-suspending centrifugal fan as claimed in claim 7, wherein: in the step S6, when the number of the blocked meshes is larger, it is proved that the more the dust in the room is, the output power of the motor needs to be increased correspondingly, and the output power of the motor is in direct proportion to the output power of the motor, and the rotating speed of the fan is increased by increasing the output power of the motor, so that the efficiency of extracting the indoor air is improved, and a large amount of dust in the room is rapidly collected and is convenient to clean.
9. The remote control system of an air-suspending centrifugal fan as claimed in claim 8, wherein: in step S2, the detection interval of the temperature and humidity sensor is inversely proportional to the output power of the motor, that is, if the current output power of the motor is larger, the influence on the indoor temperature and humidity is larger, for example, if the current indoor dust is more, the output power of the motor is increased to extract the dust and gather the dust, and after the output power of the motor is increased, the amount of air in the extracted room is also larger, which has a good cooling effect on the indoor temperature, and the change range of the temperature after the current processing is relatively smaller, so that the temperature interval is relatively increased to save the use of the temperature sensor and increase the service life of the temperature sensor.
