It should be noted that, when the main control module 101 receives the function demand instruction, the target air pressure environment state in the function demand instruction is obtained, and based on the target air pressure environment state, according to a preset air pressure adjusting mode, an adjusting instruction is issued to the air door motor, and the air door motor drives the opening range of the air inlet door and/or the air outlet door according to the adjusting instruction, so as to control the air inlet amount and the air outlet amount of the fan, and make the indoor air pressure environment state reach the target air pressure environment state. The air inlet/outlet door can be judged to be closed in place through the limit switch, and whether the air inlet/outlet door reaches the designated position is determined through the incremental feedback coding of the air door motor.
The main control module 101 is configured to obtain a target air pressure environment state carried by a function demand instruction, and issue 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 respond to the first adjustment instruction and control the rotation speed of the direct current fan 5; 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 intake and the air exhaust of the fan assembly, and the specific method steps of enabling the indoor air pressure environment state to reach the target air pressure environment state are implemented as follows:
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 be arranged at an indoor air pressure detection port and an outdoor air pressure detection port in the air sterilizing machine, wherein the indoor air pressure detection port is communicated with the indoor environment through an indoor detection pipeline, and the outdoor air pressure detection port is communicated with the outdoor environment through an outdoor detection pipeline.
2. After acquiring the target atmospheric pressure environment state carried by the function demand instruction, the main control module 101 analyzes the target atmospheric pressure environment state to obtain a target atmospheric pressure mode corresponding to the target atmospheric pressure environment state and a target atmospheric pressure value corresponding to the target atmospheric pressure mode, and calculates an actual atmospheric pressure difference value between the indoor atmospheric pressure value and the outdoor atmospheric pressure value. The target air pressure environmental state comprises a target air pressure mode and a target air pressure value corresponding to the target air pressure 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 the medium speed, so that a control margin is reserved for the subsequent stable control of the air pressure by controlling the rotating speed of the fan.
4. When the target air pressure mode is a positive pressure mode, the main control module 101 is used for comparing an actual air pressure difference value with a target air pressure difference value, if the main control module 101 judges that the actual air pressure difference value is smaller than the target air pressure difference value, a first regulating instruction is issued to the air door assembly, and at the moment, the first regulating instruction is used for enabling 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 regulating amplitude, regulating the opening amplitude of the inner air outlet door to a maximum amplitude, and regulating the opening amplitude of the outer air door to a minimum amplitude;
if the main control module 101 determines that the actual air pressure difference value is greater than the target air pressure difference value, a first adjusting instruction is issued to the air door assembly, and at this time, the first adjusting instruction is used for enabling the air door assembly to 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 adjusting amplitude, the opening amplitude of the inner air outlet door is adjusted to the maximum amplitude, and the opening amplitude of the outer air outlet door is adjusted to the minimum amplitude.
Note that, before the adjustment is performed, the adjustment range of the entrance/exit damper is set in advance as the adjustment basis. In this embodiment, the first preset adjustment range may be determined according to a rule that the opening range of the outer intake door is greater than that of the inner intake door and the sum of the opening ranges of the outer intake door and the inner intake door is 100%, and the second preset adjustment range may be determined according to a rule that the opening range of the outer intake door is less than that of the inner intake door and the sum of the opening ranges of the outer intake door and the inner intake door is 100%. It can be understood that, in the present embodiment, the number of the inner air inlet doors is two, and then the opening amplitude of the inner air inlet door refers to the sum of the opening amplitude of the first inner air inlet door 11 and the opening amplitude 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 an adjustment basis, and the first preset adjustment amplitude and the second preset adjustment amplitude are set to be 5%. According to the first preset adjustment range, the opening range of the outer air inlet door is increased, and the opening range of the inner air inlet door is reduced: the opening amplitude of the inner air inlet door is reduced by 5%, the opening amplitude of the outer air inlet door is improved 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 just kept to be 100%. According to the second preset adjustment range, the opening range of the outer air inlet door is reduced, and the opening range of the inner air inlet door is increased: 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, the opening amplitude of the inner air inlet door is 55% at the moment, and the opening amplitude of the outer air inlet door is 45%.
5. When the target air pressure mode is the negative pressure mode adjustment, 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 value is greater than the target air pressure difference value, a first adjusting instruction is issued to the air door assembly, and at the moment, 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 outgoing air door according to a third preset adjusting amplitude, the opening amplitude of the outgoing air door is adjusted to the maximum amplitude, and the opening amplitude of the outgoing air door is adjusted to the minimum amplitude;
and if the actual air pressure difference value is smaller than the target pressure difference value, issuing a first regulating instruction to the air door assembly, wherein the first regulating instruction is used for enabling the air door assembly to reduce the opening amplitude of the outgoing air door and increase the opening amplitude of the internal outgoing air door according to a fourth preset regulating amplitude, regulating the opening amplitude of the internal outgoing air 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 conditions, 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 that of the internal air outlet door, and the sum of the opening ranges of the outgoing air door and the internal air outlet 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 that of the internal air outlet door, and the sum of the opening ranges of the outgoing air door and the internal air outlet door is 100%. The control principle of the internal air outlet door and the external air outlet door is similar to that of the internal air inlet door and the external air inlet door, and the control principle is not repeated herein.
6. The main control module 101 monitors the actual indoor and outdoor air pressure difference values in real time, and sends a first adjusting instruction to the air door assembly according to the comparison result of the air pressure difference values, so that the air door assembly adjusts the opening amplitude of the air door in/out, and the actual air pressure difference value reaches a target air pressure difference value; when the air pressure difference value is monitored to be equal to the target air pressure difference value, the main control module 101 issues 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 the adjustment of the opening amplitude of the air door is stopped, if the main control module 101 monitors that the air pressure difference value at the current moment changes, the main control module 101 obtains the change value of the air pressure difference value at the current moment, calculates the target rotating speed by combining the preset rotating speed adjustment relation of the fan, and sends a first adjustment instruction to the fan assembly, so that the fan assembly adjusts the current rotating speed of the fan to the target rotating speed, and the air pressure difference value at the current moment is maintained at the target air pressure difference value.
It should be noted that, when the actual air pressure difference between the indoor and outdoor reaches the target air pressure value, the opening range of each air door at the current time is fixed, and at this time, the indoor air pressure may fluctuate and be unbalanced, so that the actual air pressure value slightly fluctuates.
Specifically, the relationship between the variation value and the fan rotation speed may be established in advance through a PID control model, and the target rotation speed may be calculated, or the relationship between the variation value and the fan rotation speed may be trained through another mathematical model. In addition, when the rotating speed of the fan is controlled, the rotating speed of the fan can be controlled through PWM pulse width modulation, and stepless control air supply is achieved.
As can be seen from the above, in this embodiment, the main control module 101 can issue an adjustment instruction to the air door motor according to a preset air pressure adjustment mode, and the air door motor drives the opening range of the air inlet door and/or the air outlet door according to the adjustment instruction, so as to control the air inlet volume and the air outlet volume of the fan, so that the indoor air pressure environment state reaches the target air pressure environment state, and thus, the adjustment and the switching of the positive pressure and the negative pressure of the indoor environment are realized.
Further, in another embodiment of the present invention, when the main control module 101 generates the first adjustment instruction and the rotation speed adjustment instruction, it indicates that the control system is about to operate in the positive/negative pressure adjustment state and the environment monitoring state, and at this time, issuing of the instruction has a priority sequence, specifically:
if the quality grade of the air quality is determined to be a first preset grade, the main control module 101 issues a rotating speed adjusting instruction to the fan assembly, and the fan assembly is used for responding to the rotating speed adjusting instruction and adjusting the rotating speed value of the direct current fan 5 to the highest rotating speed value. When the rotating speed of the direct current fan 5 is monitored to be running at the highest rotating 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 intake and the air exhaust of the fan assembly, so that the indoor air pressure environment state reaches the target air pressure environment state.
It should be noted that when the quality level of the detected air quality is the first preset level, which indicates that the current air quality is relatively poor, air purification needs to be preferentially performed at this time, the main control module preferentially issues a rotation speed adjustment instruction to the fan assembly, and the fan assembly responds to the rotation speed adjustment instruction to adjust the speed of the fan to a high speed, so as to accelerate the air purification speed. The rotating speed adjusting instruction comprises a rotating speed value related to a first preset level.
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. Since the rotation speed of the dc fan 5 changes, the indoor air pressure environment may also change, and cannot be maintained at the target air pressure environment, the opening range of the air inlet/outlet door needs to be readjusted, and the opening range of the air inlet/outlet door is controlled by the air door assembly, so as to maintain the indoor air pressure environment at the target air pressure environment. The specific control process is as follows: the main control module 101 calculates an actual air pressure difference value at the current moment, compares the actual air pressure difference value with a target air pressure difference value, and issues 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, drives the opening range of the air inlet/outlet door, and controls the air inlet amount and the air outlet amount of the fan, so that the indoor air pressure environment state is restored to the target air pressure environment state. And then, at an interval of 10 seconds, the main control module 101 executes the step of calculating the actual air pressure difference value and sending an adjusting instruction once, and dynamically adjusts the opening amplitude of the air inlet/outlet door. The specific adjustment of the opening amplitude 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 regulating instruction with a rotating speed value corresponding to the rotating speed regulating instruction, if the target rotating speed value corresponding to the first regulating instruction is larger than the rotating speed value corresponding to the rotating speed regulating instruction, the first regulating 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 regulate the air intake and the air exhaust 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 rotating speed adjusting instruction of the direct current fan 5 is monitored to correspond to the rotating speed value, 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 intake and the air exhaust of the fan assembly, so that the indoor air pressure environment state reaches the target air pressure environment state.
It should be noted that, in the positive and negative pressure regulation, the main control module calculates a target rotation speed according to a variation value of the air pressure difference at the current time and in combination with a preset fan rotation speed adjustment relationship, and issues a first regulation instruction to the fan assembly, so that the fan assembly adjusts the current fan rotation speed to the target rotation speed, where the target rotation speed at this time is a target rotation speed value corresponding to the first regulation instruction.
The air quality is that the second predetermines the grade and explains that current quality environmental conditions are general, it is preferred to purify with quick disinfection, at this moment, when the target rotational speed value that first regulation instruction corresponds is greater than the rotational speed value that rotational speed regulation instruction corresponds, when explaining mainly controlling the fan rotational speed with positive negative pressure regulation, the target of quick disinfection purification has been satisfied, and compare in the latter can be faster carry out air purification, can also satisfy indoor atmospheric pressure environmental condition and adjust simultaneously, reach the interests maximize, therefore, the fan subassembly needs the first regulation instruction of preferred execution. When the target rotating speed value corresponding to the first regulating instruction is smaller than the rotating speed value corresponding to the rotating speed regulating instruction, it is indicated that the target of rapid disinfection and purification cannot be realized when the positive pressure regulation and the negative pressure regulation are mainly used for controlling the rotating speed of the fan, so that the rotating speed value of the fan needs to be adjusted to the rotating speed value corresponding to the rotating speed regulating instruction, and rapid disinfection and purification are realized.
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 air door assembly.
It should be noted that when the air quality level is detected to be the third preset level, it is indicated that the air condition is good, and at this time, the fan assembly is preferentially used for performing positive and negative pressure adjustment to maintain the indoor air pressure environment condition at the target air pressure environment condition. The positive and negative pressure adjusting method steps can be referred to specifically.
Further, in another embodiment of the present invention, as the air purification continues, when the air quality level decreases to a third preset level, the main control module 101 issues a fourth adjustment instruction to the positive and negative pressure adjustment assemblies according to the historical adjustment record, the fan assembly responds to the fourth adjustment instruction to fix the rotation speed of the dc fan 5 to the medium-speed operation, the damper assembly responds to the fourth adjustment instruction to adjust the opening amplitude of the air inlet/outlet damper to the opening amplitude associated with the target air pressure environment state, and after the adjustment is finished, a signal that the damper is adjusted in place is fed back to the main control module 101. The main control module 101 monitors the air pressure difference value at the current moment in real time after receiving the feedback signal, obtains a change value of the air pressure difference value at the current moment when the monitored air pressure difference value at the current moment changes, calculates a target rotating speed by combining a preset fan rotating speed adjusting relation, and sends a fifth adjusting instruction to the fan assembly, so that the fan assembly adjusts the current fan rotating speed to the target rotating speed, 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 atmospheric pressure environment state can be obtained according to the historical adjustment record. The history adjustment record is formed in a specific process that, in the positive and negative pressure adjustment process, after the main control module 101 issues an instruction for stopping adjusting the opening amplitude to the air door motor, the main control module 101 records the opening amplitude of each air door at the current moment, associates the target air pressure value with the opening amplitude of each air door at the current moment, the target air pressure value and the indoor capacity, and stores the association relationship. The indoor capacity can be acquired by sending information input prompts to a user. Therefore, the main control module can call the incidence relation between the target air pressure value and the opening range of the air door from the historical adjustment record, the opening range of the air door is quickly fixed at the opening range which can enable the actual air pressure difference value to reach the target air pressure difference value according to the incidence relation, 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 through a PWM control mode, the actual air pressure difference value is maintained at the target air pressure difference value, and the positive and negative pressure adjusting speed is integrally improved.
