The specific calculation process is as follows: By calculating the formula Calculate the number of purification equipment BS corresponding to each area to be disinfected c , XQ c is the demand assessment coefficient corresponding to the cth area to be disinfected, MU c is the capacity assessment coefficient of the purification equipment corresponding to the cth area to be disinfected; The control terminal is used to turn on the purification equipment for disinfection and purification when the air quality in a certain area of ​​the hospital is unqualified, and turn off the purification equipment when the air quality in the monitored area is qualified.

2. A hospital air disinfection and purification system as claimed in claim 1, characterized in that: The specific process of judging the air quality of each area in the hospital is as follows: The air quality assessment coefficient corresponding to each area in the hospital is compared with the air quality assessment coefficient threshold stored in the database. If the air quality assessment coefficient corresponding to an area in the hospital is greater than the air quality assessment coefficient threshold stored in the database, the air quality corresponding to the area is judged to be unqualified, and the area is recorded as an area to be disinfected, and the areas to be disinfected are obtained. If the air quality assessment coefficient corresponding to an area in the hospital is less than or equal to the air quality assessment coefficient threshold stored in the database, the air quality corresponding to the area is judged to be qualified, so as to judge the air quality corresponding to each area in the hospital.

3. A purification method for implementing the hospital air disinfection and purification system according to any one of claims 1-2, characterized in that: include: Step 1: Air information collection: obtain the air information corresponding to each area in the hospital, and then analyze and obtain the air quality assessment coefficient corresponding to each area in the hospital, and judge the air quality corresponding to each area in the hospital. If the air quality corresponding to a certain area is unqualified, then the area is recorded as an area to be disinfected, and each area to be disinfected is obtained; Step 2: Obtaining patient information: Obtaining patient information corresponding to each area to be disinfected, and then analyzing and obtaining the influencing factors corresponding to each area to be disinfected; Step 3: Pathogen monitoring: Obtain the microbial aerosol type and air purification standard value corresponding to each area to be disinfected, and then screen out the required equipment type corresponding to each area to be disinfected. At the same time, obtain the air circulation speed and microbial aerosol transmission speed corresponding to each area to be disinfected, and analyze and obtain the demand assessment coefficient corresponding to each area to be disinfected according to the influencing factors corresponding to each area to be disinfected; Step 4: Purification equipment selection: obtain the function type corresponding to each purification equipment, and according to the required equipment type corresponding to each area to be disinfected, screen and obtain the purification equipment type corresponding to each area to be disinfected, and obtain the capacity information of the purification equipment corresponding to each area to be disinfected, and then analyze and obtain the capacity evaluation coefficient of the purification equipment corresponding to each area to be disinfected, and according to the demand evaluation coefficient corresponding to each area to be disinfected, calculate the number of purification equipment corresponding to each area to be disinfected; Step 5: Equipment control: When the air quality in a certain area of ​​the hospital is not up to standard, turn on the purification equipment for disinfection and purification. When the air quality in the monitored area is up to standard, turn off the purification equipment.
