Figure 2
In the [sterilization] interface, users can view sterilization timing time, set sterilization setting time and reservation function;
1. Appointment for sterilization
Users can open a key to make an appointment for sterilization, set the sterilization reservation time, click on the sterilization reservation switch, will pop up into the sterilization reservation status prompt box, click on the system will enter the sterilization reservation state;
2. Opening of sterilization
Users can directly open sterilization, click on the sterilization switch, will pop up into the sterilization state prompt box, click on the system will enter the sterilization state; note: in the front window is closed and lighting and fan closed state can open sterilization;
3. Operational log

Figure 3
4. Prompt box
When the system enters the abnormal state from the normal state or when sterilization is completed, there will be corresponding prompt information, and the user will be prompted in the form of a pop-up frame in the monitoring interface;
(1) Stop the operation of the filter clogging induced fan: when the fan is in operation, if the current pressure difference measurement value is greater than the "pressure upper limit value" for 10 seconds, the fan operation stops, the buzzer calls, and the corresponding prompt box pops up when entering the monitoring interface;
(2) When the fan is in operation, if the current pressure difference measurement value is less than the "pressure limit value" for 10 seconds, the fan operation stops, the buzzer calls, and the corresponding prompt box pops up when entering the monitoring interface;
(3) Stop the operation of the fan caused by the fluctuation of the descending airflow: when the falling fan is in operation, if the current falling wind speed measurement value continuously "alarm delay" time exceeds the ±20% of the "set falling wind speed ", the fan stops running and the buzzer calls. When entering the monitoring interface, the corresponding prompt box will pop up;
(4) The abnormal sterilization operation of the front window stops: when the sterilization is in the open state, the front window is in the non-closed area, the sterilization operation stops, the buzzer calls, and the corresponding prompt box pops up when entering the monitoring interface;
(5) When the fan is in the running state, the front window is in the non-working area, the falling fan stops running, the buzzer calls, and the corresponding prompt box pops up when entering the monitoring interface;
(6) The sterilization time arrives but can not enter the sterilization: the user has opened the reservation sterilization, and the current time has reached the sterilization reservation time, but the system can not enter the sterilization state because the front window is not closed or the lighting, the fan is open, the buzzer calls and the corresponding prompt box pops up when entering the monitoring interface;
(7) Sterilization completion: when sterilization is completed, the buzzer calls 6 times, and the corresponding prompt box pops up when entering the monitoring interface;
Note :1~5 buzzer continuous call 60 seconds after closing ;6,7 buzzer intermittent call 6 after closing; users can also click on the confirmation key to close buzzer call;

5.1.2 Fall Wind Error Correction
In order to facilitate the user to correct the sensor, the system adopts the function of three-point correction, that is, the user can correct the deviation at any three measuring points, and the system automatically corrects the other measuring points linearly.
Such as: speed at 0.10 m/s,0.31m/s,1.00m/s three measuring points to correct, when the instrument measured speed value of 0.10 m/s,0.31m/s,1.00m/s three points, using anemometer to measure the speed of 0.00 m/s,0.15m/s,0.87m/s, the correction mode is as follows:
Name | Function | Initial value (set range) |
Correction point 1 | You should enter 0.10 m/s, or 0.10 m/s as the first correction point in this example | 0.10 m/s (0.00~ correction point 2) |
Correction point 2 | Type 0.31 m/s, or 0.31 m/s as the second correction point in this example | 0.31 m/s (correction point 1~ correction point 3) |
Correction point 3 | You should enter 1.00 m/s, or 1.00 m/s as the third correction point in this example | 1.00 m/s (correction point 2~1.00) |
Calibration deviation 1 | For this example, enter m/s ,-0.10, the value of the anemometer at the first corrected velocity point - the system measurements | -0.10 m/s (-0.50~0.50) |
Calibration deviation 2 | For this example, enter -0.16 m/s, the value of the anemometer at the second corrected velocity point - the system measurements | -0.16 m/s (-0.50~0.50) |
Calibration deviation 3 | For this example, enter -0.13 m/s, the value of the anemometer at the third corrected velocity point - system measurements | -0.13 m/s (-0.50~0.50) |
