When the main control module 101 receives the function demand instruction, it obtains the target air pressure environment state in the function demand instruction, and based on the target air pressure environment state, issues a regulating instruction to the air door motor according to a preset air pressure regulating mode, and the air door motor drives the opening amplitude of the air inlet door and/or the air outlet door according to the regulating instruction, so as to control the air inlet quantity and the air outlet quantity of the fan, and make the indoor air pressure environment state reach the target air pressure environment state. Whether the air inlet door and the air outlet door are closed in place or not can be judged through a limit switch, and whether the air inlet door and the air outlet door reach a designated position or not is determined through incremental feedback codes of an air door motor.
The main control module 101 is configured to obtain a target air pressure environment state carried by a functional demand instruction, and send a first adjustment instruction to the positive and negative pressure adjustment assembly according to a preset air pressure adjustment relationship, and the fan assembly is configured to control a rotation speed of the direct current fan 5 in response to the first adjustment instruction; the air door assembly is used for responding to the first adjusting instruction, controlling the opening amplitude of the air door to adjust the air inlet quantity and the air outlet quantity of the fan assembly, so that the indoor air pressure environment state reaches the target air pressure environment state, and the specific method comprises the following steps:
1. the micro differential pressure sensor acquires an indoor air pressure value and an outdoor air pressure value in real time, and uploads the indoor air pressure value and the outdoor air pressure value to the main control module 101. Wherein, the micro-pressure sensor can set up the indoor air pressure detection mouth and the outdoor air pressure detection mouth in the air sterilizer, and wherein, indoor air pressure detection mouth is through indoor detection pipeline and indoor environment intercommunication, and outdoor air pressure detection mouth is through outdoor detection pipeline and outdoor environment intercommunication.
2. After the master control module 101 obtains the target air pressure environment state carried by the function demand instruction, the target air pressure mode corresponding to the target air pressure environment state and the target air pressure value corresponding to the target air pressure mode are obtained through analysis, and the actual air pressure difference value between the indoor air pressure value and the outdoor air pressure value is calculated. The target barometric environment state comprises a target barometric mode and a target barometric value corresponding to the target barometric mode. The target air pressure mode includes a positive pressure mode and a negative pressure mode.
3. After the target mode and the target air pressure difference value are obtained, the main control module 101 issues a first adjusting instruction to the fan assembly, and at this time, the first adjusting instruction is used for enabling the fan assembly to adjust the rotating speed of the direct current fan 5 to a medium speed, so that a control allowance is reserved for maintaining air pressure stable control by controlling the rotating speed of the fan.
4. When the target air pressure mode is the positive pressure mode, the main control module 101 is configured to compare the actual air pressure difference value with the target air pressure difference value, and if the main control module 101 determines that the actual air pressure difference value is smaller than the target air pressure difference value, issue a first adjustment instruction to the air door assembly, where the first adjustment instruction is configured to cause the air door assembly to increase the opening amplitude of the outer air inlet door and decrease the opening amplitude of the inner air inlet door according to a first preset adjustment amplitude, adjust the opening amplitude of the inner air outlet door to a maximum amplitude, and adjust the opening amplitude of the outer air inlet door to a minimum amplitude;
if the main control module 101 determines that the actual air pressure difference is greater than the target air pressure difference, a first adjustment instruction is issued to the air door assembly, and at this time, the first adjustment instruction is used to make the air door assembly reduce the opening amplitude of the outer air inlet door and increase the opening amplitude of the inner air inlet door according to a second preset adjustment amplitude, adjust the opening amplitude of the inner air outlet door to a maximum amplitude, and adjust the opening amplitude of the outer air inlet door to a minimum amplitude.
Before the adjustment, the adjustment range of the inlet/outlet damper is set in advance as the adjustment basis. The first preset adjustment range and the second preset adjustment range may be preset according to actual situations, in this embodiment, the first preset adjustment range may be determined according to a rule that the opening range of the outer air inlet door is greater than that of the inner air inlet door and the sum of the opening ranges of the outer air inlet door and the inner air inlet door is 100%, and the second preset adjustment range may be determined according to a rule that the opening range of the outer air inlet door is less than that of the inner air inlet door and the sum of the opening ranges of the outer air inlet door and the inner air inlet door is 100%. It will be appreciated that in this embodiment, the number of the inner air inlet doors is two, and the opening width of the inner air inlet door refers to the sum of the opening width of the first inner air inlet door 11 and the opening width of the second inner air inlet door 12. For example: the opening amplitude of the outer air inlet door and the opening amplitude of the inner air inlet door are adjusted to 50% in advance to serve as adjustment bases, and the first preset adjustment amplitude and the second preset adjustment amplitude are set to be 5%. The opening amplitude of the outer air inlet door is increased and the opening amplitude of the inner air inlet door is reduced according to the first preset adjusting amplitude: the opening amplitude of the inner air inlet door is reduced by 5%, the opening amplitude of the outer air inlet door is increased by 5%, so that the opening amplitude of the outer air inlet door is larger than that of the inner air inlet door, at the moment, the opening amplitude of the inner air inlet door is 45%, the opening amplitude of the outer air inlet door is 55%, and the sum of the opening amplitude of the outer air inlet door and the opening amplitude of the inner air inlet door is exactly 100%. The opening amplitude of the outer air inlet door is reduced according to the second preset adjusting amplitude, and the opening amplitude of the inner air inlet door is increased as follows: the opening amplitude of the outer air inlet door with the amplitude of 5% is reduced, the opening amplitude of the inner air inlet door with the amplitude of 5% is improved, the opening amplitude of the inner air inlet door is larger than that of the outer air inlet door, at the moment, the opening amplitude of the inner air inlet door is 55%, and the opening amplitude of the outer air inlet door is 45%.
5. When the target air pressure mode is the negative pressure mode, the main control module 101 is used for comparing the actual air pressure value with the target air pressure difference value,
if the main control module 101 determines that the actual air pressure difference is greater than the target air pressure difference, issuing a first adjusting instruction to the air door assembly, wherein the first adjusting instruction is used for enabling the air door assembly to increase the opening amplitude of the outgoing air door and decrease the opening amplitude of the internal air door according to a third preset adjusting amplitude, adjusting the opening amplitude of the internal air door to the maximum amplitude and adjusting the opening amplitude of the outgoing air door to the minimum amplitude;
if the actual air pressure difference is smaller than the target air pressure difference, a first regulating instruction is issued to the air door component, and at the moment, the first regulating instruction is used for enabling the air door component to reduce the opening amplitude of the outgoing air door and increase the opening amplitude of the internal air outlet door according to a fourth preset regulating amplitude, regulating the opening amplitude of the internal air outlet door to the maximum amplitude, and regulating the opening amplitude of the outgoing air door to the minimum amplitude.
It should be noted that, the third preset adjustment range and the fourth preset adjustment range may be set according to actual situations, in this embodiment, the third preset adjustment range may be determined according to a rule that the opening range of the outgoing air door is greater than the opening range of the internal air door and the sum of the opening ranges of the outgoing air door and the internal air door is 100%, and the fourth preset adjustment range may be determined according to a rule that the opening range of the outgoing air door is less than the opening range of the internal air door and the sum of the opening ranges of the outgoing air door and the internal air door is 100%. The control principle of the inner air inlet door and the outer air inlet door is similar to that of the inner air inlet door and the outer air inlet door, and the control principle is not repeated here.
6. The main control module 101 monitors the actual air pressure difference between the indoor air pressure and the outdoor air pressure in real time, and issues a first adjusting instruction to the air door assembly according to the comparison result of the air pressure difference, so that the air door assembly adjusts the opening amplitude of the inlet/outlet air door to enable the actual air pressure difference to reach the target air pressure difference; when the air pressure difference is equal to the target air pressure difference, the main control module 101 sends a first adjusting instruction to the air door assembly, so that the air door assembly stops adjusting the opening amplitude of the air door.
7. After stopping adjusting the opening amplitude of the air door, if the main control module 101 monitors that the air pressure difference value at the current moment changes, the main control module 101 acquires a change value of the air pressure difference value at the current moment, calculates a target rotating speed according to a preset fan rotating speed adjusting relation, and issues a first adjusting instruction to the fan assembly, so that the fan assembly adjusts the current fan rotating speed to the target rotating speed, and the air pressure difference value at the current moment is maintained at the target air pressure difference value.
When the actual air pressure difference between the indoor and the outdoor reaches the target air pressure value, the opening amplitude of each air door at the current moment is fixed, at this time, the indoor air pressure may be fluctuated or unbalanced, so that the actual pressure difference value may slightly change, the target rotating speed is calculated according to the adjustment relation between the changing value and the rotating speed of the fan by obtaining the changing value of the actual air pressure difference value, and the current rotating speed of the fan is adjusted to the target rotating speed, so that the air inlet/outlet volume can be controlled by controlling the rotating speed of the air door motor at this time, and the indoor air pressure environment state is finely adjusted, so that the indoor and outdoor actual air pressure difference value is maintained at the target air pressure value, and the air pressure balance is maintained.
Specifically, the relation between the change value and the fan rotating speed adjustment can be established in advance through a PID control model, and the target rotating speed is calculated, or the relation between the change value and the fan rotating speed adjustment can be trained through other mathematical models. In addition, when the fan rotating speed control is performed, the rotating speed of the fan can be controlled through PWM pulse width modulation, so that stepless control of air supply is achieved.
As can be seen from the foregoing, in this embodiment, the main control module 101 may send a regulating command to the damper motor according to a preset air pressure regulating manner, and the damper motor drives the opening amplitude of the air inlet damper and/or the air outlet damper according to the regulating command, so as to control the air inlet amount and the air outlet amount of the fan, so that the indoor air pressure environment state reaches the target air pressure environment state, and thus, the regulation and the switching of the positive and negative pressures of the indoor environment are realized.
Further, in another embodiment of the present invention, when the main control module 101 generates the first adjustment command and the rotation speed adjustment command, it indicates that the control system is about to operate in the positive and negative pressure adjustment and environment monitoring states, and the issuing of the commands will have a priority order, specifically:
if the quality level of the air quality is determined to be the first preset level, the main control module 101 issues a rotation speed adjusting instruction to the fan assembly, and the fan assembly is used for responding to the rotation speed adjusting instruction and adjusting the rotation speed value of the direct current fan 5 to the highest rotation speed value. When the rotation speed of the direct current fan 5 is monitored to be at the highest rotation speed, the main control module 101 issues a first adjusting instruction to the air door assembly, so that the air door assembly responds to the first adjusting instruction, and the opening amplitude of the air door is controlled to adjust the air inlet quantity and the air outlet quantity of the fan assembly, so that the indoor air pressure environment state reaches the target air pressure environment state.
When the detected air quality is of a first preset level, the current air quality is worse, and air purification is required to be performed preferentially, the main control module issues a rotating speed adjusting instruction to the fan assembly preferentially, and the fan assembly responds to the rotating speed adjusting instruction to adjust the fan speed to be high, so that the air purification speed is increased. The rotating speed adjusting instruction comprises a rotating speed value related to a first preset grade.
It should be noted that, after the fan assembly completes the rotation speed adjustment of the direct current fan 5, the direct current fan 5 works at a fixed adjustment rotation speed until the air quality level changes. Because the rotation speed of the direct current fan 5 changes, the indoor air pressure environment state may also change and cannot be maintained in the target air pressure environment state, the opening amplitude of the air inlet/outlet door needs to be readjusted, and the opening amplitude of the air inlet/outlet door is controlled through the air door assembly to maintain the indoor air pressure environment state in the target air pressure environment state. The specific control process is as follows: the main control module 101 calculates the actual air pressure difference value at the current moment, compares the actual air pressure difference value with the target air pressure difference value, and sends a first adjusting instruction to the air door assembly according to the comparison result, and the air door assembly responds to the first adjusting instruction and drives the opening amplitude of the air inlet/outlet door to control the air inlet quantity and the air outlet quantity of the fan so as to enable the indoor air pressure environment state to be restored to the target air pressure environment state. After that, the main control module 101 performs a step of calculating the actual air pressure difference to issue an adjustment command every 10 seconds, and dynamically adjusts the opening amplitude of the inlet/outlet air door. The specific opening amplitude adjustment of the inlet/outlet damper can refer to the method steps for adjusting the positive and negative pressure modes.
If the quality grade is determined to be a second preset grade, the main control module 101 compares a target rotating speed value corresponding to the first adjusting instruction with a rotating speed value corresponding to the rotating speed adjusting instruction, if the target rotating speed value corresponding to the first adjusting instruction is larger than the rotating speed value corresponding to the rotating speed adjusting instruction, the first adjusting instruction is issued to the fan assembly and the air door assembly, so that the fan assembly controls the rotating speed of the direct current fan 5, and the air door assembly controls the opening amplitude of the air door to adjust the air inlet quantity and the air outlet quantity of the fan assembly, so that the indoor air pressure environment state reaches the target air pressure environment state; and if the target rotating speed value corresponding to the first adjusting instruction is smaller than the rotating speed value corresponding to the rotating speed adjusting instruction, issuing the rotating speed adjusting instruction to the fan assembly. When the corresponding rotating speed value of the rotating speed operation rotating speed adjusting instruction of the direct current fan 5 is monitored, the main control module 101 issues a first adjusting instruction to the air door assembly, so that the air door assembly responds to the first adjusting instruction, the opening amplitude of the air door is controlled to adjust the air inlet quantity and the air outlet quantity of the fan assembly, and the indoor air pressure environment state reaches the target air pressure environment state.
In the positive and negative pressure adjustment, the main control module calculates a target rotation speed according to a variation value of the air pressure difference value at the current moment and a preset fan rotation speed adjustment relation, and issues a first adjustment instruction to the fan assembly to enable the fan assembly to adjust the current fan rotation speed to the target rotation speed, wherein the target rotation speed at the moment is the target rotation speed value corresponding to the first adjustment instruction.
The air quality is the second preset level to indicate that the current quality environment condition is general, the quick disinfection and purification are required to be prioritized, at this time, when the target rotating speed value corresponding to the first adjusting instruction is larger than the rotating speed value corresponding to the rotating speed adjusting instruction, the air quality is mainly used for controlling the rotating speed of the fan, the goal of quick disinfection and purification can be met, and compared with the second adjusting instruction, the air quality can be more quickly purified, and meanwhile, the indoor air pressure environment condition adjustment can be met, so that the benefit is maximized, and therefore, the fan assembly is required to preferentially execute the first adjusting instruction. When the target rotating speed value corresponding to the first adjusting instruction is smaller than the rotating speed value corresponding to the rotating speed adjusting instruction, the positive and negative pressure is mainly adjusted to control the rotating speed of the fan, and the aim of quick disinfection and purification cannot be achieved, so that the rotating speed value of the fan needs to be adjusted to the rotating speed value corresponding to the rotating speed adjusting instruction, and quick disinfection and purification are achieved.
If the quality grade is determined to be the third preset grade, the main control module 101 issues a first adjusting instruction to the fan assembly and the damper assembly.
When the air quality level is detected to be the third preset level, the air state is good, and the fan assembly is preferentially used for positive and negative pressure adjustment, so that the indoor air pressure environment state is maintained to be the target air pressure environment state. Reference may be made in particular to the aforementioned positive and negative pressure regulation method steps.
Further, in another embodiment of the present invention, as the air purification continues, after the air quality level decreases to the third preset level, the main control module 101 records and sends a fourth adjustment command to the positive and negative pressure adjustment assembly according to the history adjustment, the fan assembly responds to the fourth adjustment command to fix the rotation speed of the dc fan 5 to the medium speed operation, the air door assembly responds to the fourth adjustment command to adjust the opening amplitude of the air inlet/outlet door to the opening amplitude associated with the target air pressure environment state, and after the adjustment is finished, the signal of the air door adjustment in place is fed back to the main control module 101. After receiving the feedback signal, the main control module 101 monitors the air pressure difference value at the current moment in real time, and when the air pressure difference value at the current moment is monitored to change, obtains the change value of the air pressure difference value at the current moment, calculates the target rotating speed by combining with the preset fan rotating speed adjusting relation, and issues a fifth adjusting instruction to the fan assembly, so that the fan assembly adjusts the current fan rotating speed to the target rotating speed, and the air pressure difference value at the current moment is maintained at the target air pressure difference value, and the indoor air pressure environment state is maintained at the target air pressure environment state. The opening amplitude associated with the target barometric environment state can be obtained according to the history adjustment record. The history adjustment record is specifically formed in the process of positive and negative pressure adjustment, after the main control module 101 issues an instruction for stopping adjustment of opening amplitude to the air door motor, the main control module 101 records opening amplitude of each air door at the current moment, correlates a target air pressure value with opening amplitude of each air door at the current moment, a target air pressure value and indoor capacity, and stores a correlation. The indoor capacity can be obtained by sending information input reminding to a user. Therefore, the main control module can call the association relation between the target air pressure value and the opening amplitude of the air door from the history adjustment record, and according to the association relation, the opening amplitude of the air door is quickly fixed to the opening amplitude which can enable the actual air pressure difference value to reach the target air pressure difference value, so that the speed of enabling the actual air pressure difference value to reach the target air pressure difference value is accelerated, finally, the rotating speed of the fan is controlled in a PWM control mode, the actual air pressure difference value is maintained at the target air pressure difference value, and the speed of regulating positive and negative pressure is integrally improved.

In this embodiment, the disinfection assembly disinfects and purifies the indoor air received from the inner air inlet door, and then the indoor air is discharged to the room through the inner air outlet door, so as to realize the circulation and purification of the indoor environment.

For example, the user may select a positive pressure function in the touch screen and input a target positive air pressure value for adjustment by the system.
In this embodiment of the present invention, the main control module 101 is further configured to accumulate the working operation time of the primary filter screen 7 and the efficient filter screen 4 when the disinfection assembly 102 is started, and send out a replacement reminder when the working operation time of the primary filter screen 7 and/or the working operation time of the efficient filter screen 4 is greater than a first preset time threshold.

The first preset time threshold may be determined according to an actual situation.
The main control module 101 may send a replacement reminder to the touch screen 203, so that the touch screen 203 displays the replacement reminder. The main control module 101 sends out replacement reminding according to the working running time of the primary filter screen 7 and/or the working running time of the efficient filter screen 4, so that a user can know the condition of the filter screen conveniently and replace the filter screen timely, a large number of dirt particles are prevented from accumulating on the filter screen, the effect of filtering and purifying air is weakened, and more humanized use experience is provided for the user.
In this embodiment of the present invention, the main control module 101 is further configured to accumulate the operation time of the plasma sterilizer 2 when the sterilization assembly 102 is started, and send out a cleaning reminder if the operation time of the plasma sterilizer 2 is greater than a second preset time threshold.
It should be noted that the second preset time threshold may be determined according to an actual situation.
The main control module 101 can transmit the cleaning prompt to the touch screen and display the cleaning prompt, and a user can know the state of the plasma sterilizer 2 in time according to the cleaning prompt displayed in the touch screen 203.
In the embodiment of the present invention, the main control module 101 is further configured to monitor a real-time rotation speed value of the fan, and determine whether the fan fails according to a comparison result between the real-time rotation speed value of the fan and a preset rotation speed value; and if the fan is judged to be faulty, a fault prompt is sent out.
The fan is a speed-adjustable direct current fan 5. Specifically, according to a comparison result of the real-time rotating speed value and the preset rotating speed value of the fan, whether the fan fails or not is judged.
It should be noted that, the fan runs one circle and feeds back one pulse to the main control module 101, and the main control module 101 obtains the actual rotation speed value of the fan through pulse counting.
Wherein, according to the comparison result of the real-time rotation speed value and the preset rotation speed value of the fan, the step of judging whether the fan has faults comprises the following steps:
and if the real-time rotating speed value is smaller than the preset rotating speed value, judging that the fan fails. The calculation formula of the preset rotating speed value is as follows: (X) aim *V max * a) 100%, where a is the scaling factor, V max Is the highest rotation speed of the fan, X aim Is the actual PWM value. In this example, a is 10%.
It should be noted thatThe main control module 101 realizes stepless speed regulation of the fan in a PWM control mode. V (V) max Can be the standard specification of the blower to mark the highest rotating speed of the blower, X aim The PWM value actually generated in the fan speed is controlled for the main control module 101.
For example, in the specification of the fan, the maximum rotation speed of the fan is 3600rpm, the corresponding PWM value of the rotation speed is 100%, and when the output PWM value of the sterilizer controller is 30%, the preset rotation speed value is: (30% ×3600×10%)/100% =108 rpm.

the main control module 101 is connected with the electric door and is used for responding to the electric door control signal and controlling the electric door of the laminar flow hood 8 to open and close.
It should be noted that the purification module includes the high-efficiency filter screen 4. The air detection module includes an environmental quality sensor.
The inner air outlet 5 of the sterilizer 1 is connected with the air inlet of the laminar flow hood 8 through a pipeline so as to convey the sterilized air into the laminar flow hood 8. The sterilizer 1 is also provided with an electrical interface, and is electrically connected with the laminar flow hood 8 through a connector, so that a connection relationship between a main control module 101 in a sterilizing equipment control system and each module in the laminar flow hood 8 is established.
After the connection between the sterilizer 1 and the laminar flow hood 8 is established, a user can set the operation mode of the sterilizer 1 to be a laminar flow hood mode in the touch screen of the sterilizer 1, and the touch screen generates a laminar flow hood mode starting instruction. After receiving the start command of the laminar flow hood mode sent by the touch screen, the main control module 101 issues a second adjustment command to the air door assembly, and the air door assembly is used for responding to the second adjustment command, adjusting the opening amplitude of the inner air inlet door and the inner air outlet door to be maximum, and adjusting the opening amplitude of the outer air inlet door and the outer air inlet door to be minimum. The sterilizing machine 1 supplies the sterilized and purified air from the inner air outlet 5 to the air inlet at the top of the laminar flow hood 8, and then the sterilized and purified air is supplied into the laminar flow hood 8 through the high-efficiency filter screen 4 arranged at the air inlet of the laminar flow hood 8.
The environmental quality sensor provided in the laminar flow hood 8 detects air quality data inside the laminar flow hood 8 and feeds back the air quality data to the main control module 101. Wherein the air quality data comprises a PM2.5 value. The main control module 101 compares the PM2.5 value with a preset threshold range, and issues a third adjustment instruction to the fan assembly according to the comparison result.
If the PM2.5 value is 115ug/m 3 In the above case, the third adjustment instruction is used for enabling the fan assembly to adjust the fan rotation speed to be high;

When the PM2.5 value is 35-115ug/m 3 When the air quality in the laminar flow hood 8 is middle, the rotating speed of the fan is adjusted to be in medium-speed operation, the aim of purifying air quickly can be achieved, meanwhile, energy conservation is achieved, and noise generated by operation of the fan is reduced. When the value of PM2.5 is 35ug/m 3 In the following, the air quality inside the laminar flow hood 8 is good, and the fan is adjusted to operate at a low speed, so that the electric energy saving is realized.
It should be noted that the high speed, the medium speed and the low speed of the fan rotation speed can be set according to the specific value of the highest rotation speed in the fan specification and the actual situation.
