The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention.

It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

The vehicle-mounted negative pressure sterilization method provided by the embodiment of the invention is applied to vehicle-mounted negative pressure sterilization equipment, and the execution main body of the vehicle-mounted negative pressure sterilization method is a controller in the vehicle-mounted negative pressure sterilization equipment, as shown in fig. 1, a schematic flow diagram of the vehicle-mounted negative pressure sterilization method is shown, and the steps included in the method are specifically described below with reference to fig. 1.

And S101, acquiring target characteristic parameters in the vehicle-mounted negative pressure disinfection and sterilization equipment.

Wherein, target characteristic parameter can include the current wind pressure inside and outside the equipment and/or the current temperature in the cavity, on-vehicle type negative pressure disinfection and sterilization equipment can be used for treating the air of treating the disinfection and sterilization and handle, can include impurity such as dust, particulate matter and virus, harmful germ such as bacterium and harmful ingredient such as formaldehyde, benzene series thing, organic in the air of treating. For example, since the apparatus is a vehicle-mounted type negative pressure sterilization apparatus, it can be considered that the current wind pressure inside and outside the apparatus may be the current wind pressure inside and outside the vehicle.

Specifically, a sensor can be arranged in an air outlet of the vehicle-mounted negative pressure sterilization equipment, the sensor can be used for detecting target characteristic parameters in the vehicle-mounted negative pressure sterilization equipment, the sensor can also be used for detecting the current air pressure inside and outside the equipment and/or the current temperature in the cavity, and the detected current air pressure and/or the detected current temperature are/is sent to the controller. Thus, the controller may receive the current wind pressure inside and outside the apparatus and/or the current temperature within the cavity as detected by the sensor. For example, a temperature sensor can be arranged to detect the temperature in the cavity, and a wind pressure sensor can be arranged to detect the wind pressure inside and outside the equipment.

In addition, when acquiring the target characteristic parameters in the vehicle-mounted negative pressure disinfection and sterilization equipment, the controller can acquire the target characteristic parameters independently or simultaneously, for example, the current air pressure inside and outside the equipment can be acquired firstly, then the current temperature in the cavity can be acquired, the current temperature in the cavity can be acquired firstly, then the current air pressure inside and outside the equipment can be acquired, and the current air pressure inside and outside the equipment and the current temperature in the cavity can be acquired simultaneously. And is not particularly limited herein.

And the controller can acquire the target characteristic parameters in the vehicle-mounted type negative pressure sterilization equipment in real time, and can also periodically acquire the target characteristic parameters in the vehicle-mounted type negative pressure sterilization equipment. And is not particularly limited herein.

And S102, determining a target processing strategy matched with the target characteristic parameters.

Specifically, when receiving a target characteristic parameter sent by a sensor, the controller may match the target characteristic parameter with preset reference characteristic information, so as to obtain a target processing strategy matched with the target characteristic parameter; when the target characteristic parameter includes the current wind pressure inside and outside the device and/or the current temperature in the cavity, the preset reference characteristic information may include a preset negative pressure reference condition and/or a preset reference temperature.

Therefore, when the target characteristic parameter includes the current wind pressure inside and outside the apparatus and the current wind pressure is the first current wind pressure inside the apparatus and the second current wind pressure outside the apparatus, the step S102 may be implemented by the following sub-steps:

and S1021, matching the first current wind pressure with the second current wind pressure to obtain a first target matching result.

Specifically, when the controller acquires a first current wind pressure in the equipment and a second current wind pressure outside the equipment via the sensor, the controller may further match the first current wind pressure with the second current wind pressure, for example, compare the first current wind pressure with the second current wind pressure in size, so as to obtain a first target matching result. The first target matching result may be a size comparison result.

Step S1022, when the first target matching result indicates that the first current wind pressure is lower than the second current wind pressure, determining a target processing policy including continuing to execute target killing processing.

Specifically, when the controller determines that a first target matching result represents that a first current wind pressure in the equipment is lower than a second current wind pressure outside the equipment, the controller can determine that the current wind pressure inside and outside the equipment meets a preset negative pressure reference condition and can form negative pressure, and at the moment, can determine a target processing strategy including continuing to execute target killing processing, so that the air to be processed enters the equipment under the negative pressure condition to be subjected to the target killing processing to generate clean air which meets an air emission standard, does not influence human health and does not generate secondary pollution; wherein, the preset negative pressure reference condition may include that a first current wind pressure inside the apparatus is lower than a second current wind pressure outside the apparatus.

And S1023, when the first target matching result represents that the first current wind pressure is higher than the second current wind pressure, determining a target processing strategy comprising adjusting the rotating speed of the fan.

Specifically, when the controller determines that a first current air pressure in the first target matching result representation device is higher than a second current air pressure outside the device, the controller may determine that the current air pressure inside and outside the device does not satisfy a preset negative pressure reference condition and cannot form a negative pressure, and at this time, may determine a target processing strategy including adjusting the rotation speed of the fan, so that the adjusted air pressure inside and outside the device satisfies the preset negative pressure reference condition.

In the actual process, when the target characteristic parameter includes the current temperature in the cavity, the step S102 may be implemented by the following sub-steps:

and step S11, matching the current temperature with a preset reference temperature to obtain a second target matching result.

The preset reference temperature can be used for representing that the temperature in the cavity is enough to indicate that the cavity can normally process the air to be processed to reach the standard and can not generate secondary pollution or harm human health. The preset reference temperature may be a reference temperature threshold or a reference temperature range. And is not limited herein.

Specifically, when the controller acquires the current temperature of the cavity of the vehicle-mounted negative pressure sterilization device through the sensor, the current temperature may be further matched with a preset reference temperature, for example, the current temperature is compared with a reference temperature threshold, or the current temperature is respectively compared with the maximum value and the minimum value of a reference temperature range, so as to obtain a second target matching result.

And step S12, when the second target matching result indicates that the current temperature is higher than the preset reference temperature, determining a target processing strategy comprising reducing microwave power and/or executing over-temperature protection.

Specifically, when the controller determines that the second target matching result represents that the current temperature of the cavity of the vehicle-mounted negative pressure sterilization device is higher than the preset reference temperature, it can be considered that the temperature of the cavity of the vehicle-mounted negative pressure sterilization device is too high and ignition is easily caused in the cavity, and at this time, a target processing strategy including reduction of microwave power and/or execution of over-temperature protection can be determined, so that the purpose of protecting the vehicle-mounted negative pressure sterilization device is achieved. The current temperature of the cavity of the vehicle-mounted negative pressure sterilization device is higher than the preset reference temperature, and the current temperature may be higher than the reference temperature threshold or higher than the maximum value of the reference temperature range.

And step S13, when the second target matching result indicates that the current temperature is lower than the preset reference temperature, determining a target processing strategy including continuing to execute target killing processing.

Specifically, when the controller determines that the third target matching result represents that the current temperature of the cavity of the vehicle-mounted negative pressure sterilization equipment is lower than the preset reference temperature, the temperature of the cavity of the vehicle-mounted negative pressure sterilization equipment is normal and ignition in the cavity cannot be caused, and at the moment, a target processing strategy including continuing to execute target sterilization treatment can be determined, so that the air to be treated entering the vehicle-mounted negative pressure sterilization equipment can be quickly and efficiently processed into clean air which reaches the standard and cannot generate secondary pollution or harm human health; the current temperature of the cavity of the vehicle-mounted negative pressure sterilization device is lower than the preset reference temperature, and the current temperature may be lower than or equal to a reference temperature threshold, the current temperature is lower than the minimum value of the reference temperature range, or the current temperature is between the minimum value and the maximum value of the reference temperature range.

In the actual processing process, when the target characteristic parameters acquired by the controller include the current air pressure inside and outside the equipment and the current temperature inside the cavity, the first current air pressure inside the equipment and the second current air pressure outside the equipment can be further matched, the current temperature is matched with the preset reference temperature, the first matching result and the second matching result are obtained, and the target processing strategy corresponding to the first matching result and the second matching result is determined. The specific matching process is as described in the foregoing embodiments, and is not described herein again.

And step S103, controlling to perform target processing according to the target processing strategy.

In the actual processing procedure, the specific implementation procedure of step S103 may include the following sub-steps:

and step S1031, when determining a target processing strategy comprising reducing the microwave power and/or executing over-temperature protection, controlling to reduce the power of a microwave source arranged in the microwave ultraviolet processing area and/or starting an over-temperature protection circuit to obtain information after target adjustment.

Specifically, when the controller determines a target processing strategy including reducing microwave power and/or executing over-temperature protection, the controller may consider that the current temperature of the cavity of the vehicle-mounted negative pressure sterilization equipment is higher than a preset reference temperature, and at this time, the controller may further control to reduce the power of the microwave source and/or start the over-temperature protection circuit according to a temperature difference between the current temperature and the preset reference temperature; furthermore, when the temperature difference is too large, the equipment can be directly closed, so that the purpose of protecting the equipment is achieved.

The target adjusted information may include adjusted power of the microwave source after the power is reduced and/or indication information for indicating that the over-temperature protection circuit is activated.

And S1032, under the action of the target adjusted information, controlling to continuously execute target sterilization treatment operation of the air to be treated entering the equipment.

Specifically, the controller can control the equipment to continue target sterilization treatment on the air to be treated entering the vehicle-mounted negative pressure sterilization equipment under the action of the target-adjusted information, so that harmful bacteria such as viruses and bacteria and harmful components such as formaldehyde and benzene series in the air to be treated can be efficiently and quickly treated.

It should be noted that, when the controller determines the target processing strategy including adjusting the rotation speed of the fan, the controller may further control to adjust the rotation speed of the fan, so that negative pressure can be formed after the rotation speed of the fan is adjusted.

In the actual processing, the method may further include:

and step S21, obtaining biological characteristic information in the cavity.

The biometric information may include a fingerprint, iris, facial, etc. physiological features inherent to a person.

Specifically, in order to process bacteria, viruses and the like attached to or remaining on the surfaces of the wall bodies and the like inside the equipment when no person exists inside the equipment, a sensor can be arranged to detect biological characteristic information in the cavity, the biological characteristic information is generated to be used as a controller, and the controller can acquire the biological characteristic information in the cavity in real time or periodically so as to judge whether a person exists in the cavity or not.

And step S22, controlling the fan to rotate reversely when the biological characteristic information represents that no person is in the cavity.

Specifically, when the controller acquires the biological characteristic information sent by the sensor, the biological characteristic information can be further analyzed to determine whether the biological characteristic information represents that no person is in the cavity, and when no person is in the cavity, the fan can be controlled to rotate reversely, so that air can be blown towards the inside of the cavity after the fan rotates reversely.

And step S23, sterilizing the germs and bacteria in the cavity based on the ozone formed by the reverse rotation of the fan.

In the actual processing procedure, step S23 can be realized by the following steps:

and S231, acquiring the current concentration of the ozone formed after the fan is reversely rotated.

Specifically, because the ozone can be formed under the reverse rotation of the fan and can treat bacteria, viruses and the like in the equipment when the negative pressure ambulance of the load equipment stops, the controller can acquire the current concentration of the ozone in real time or periodically so as to conveniently judge that the wet method of the current concentration can be used for killing the viruses, the bacteria and the like subsequently.

And step S232, determining that the target ozone is formed when the current concentration reaches a preset reference concentration.

The preset reference concentration can be used for representing that the concentration of ozone is enough to indicate that the ozone can treat bacteria, viruses and the like attached to other surfaces such as the inner wall of the cavity, and the target ozone can be the ozone with the preset reference concentration.

Specifically, when the controller determines that the current concentration of ozone reaches the preset reference concentration, it may be considered that the concentration of ozone corresponding to the current concentration reaches the preset reference concentration, that is, the target ozone is generated.

And step S233, acquiring the accumulated time of the target ozone entering the cavity to carry out virus and bacteria killing treatment.

Before performing step S233, the method may further include:

and step S31, acquiring the current power of the microwave source and the current rotating speed of the fan.

Specifically, when the controller determines that the target ozone is formed, the current power of the microwave source and the current rotating speed of the fan can be further obtained, so as to judge whether the current microwave power can meet the condition of microwave electrodeless ultraviolet treatment or not and judge whether the current rotating speed can form negative pressure or not based on the current power.

And step S32, controlling a timer to start timing when the current power reaches the preset reference power and the current rotating speed reaches the preset reference rotating speed.

Specifically, when the controller determines that the current power of the microwave source reaches the preset reference power and the current rotating speed of the fan reaches the preset reference rotating speed, the current power of the microwave source can be considered to be capable of determining the treatment efficiency of the microwave electrodeless ultraviolet and forming negative pressure, and at the moment, the controller can further control the start timer to start timing, so that the treatment time of the target ozone is obtained. On the contrary, when the controller determines that the current power of the microwave source does not reach the preset reference power and the current rotating speed of the fan does not reach the preset reference rotating speed, the power of the microwave source and the rotating speed of the fan can be controlled and adjusted so as to meet the conditions that the power of the microwave source reaches the preset reference power and the rotating speed of the fan reaches the preset reference rotating speed.

And S234, controlling the fan to rotate forwards and discharging the target ozone when the accumulated time reaches a preset reference time.

The preset reference time can be used for representing that bacteria, viruses and the like attached to each surface inside the cavity can be completely treated.

Specifically, when the controller determines that the accumulated time displayed by the timer reaches the preset reference time, the controller can think that the target ozone has completely treated bacteria, viruses and the like attached to the surfaces in the cavity, and at the moment, the controller can prompt the current state, control the fan to rotate forwards and discharge the target ozone.
