Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

As shown in fig. 1, a system for killing microorganisms and germs by chemical contact according to an embodiment of the present invention includes: the system comprises a control module, an adding medicament execution module, a medicament caching module, a medicament supplementing module and a disinfection execution module; wherein:

the control module is respectively connected with the control ends of the medicament adding execution module, the medicament cache module, the medicament supplement module and the disinfection execution module, is used for controlling the modules and realizes accurate medicament feeding based on data model and sensing control cooperation;

the medicament adding execution module is connected with the medicament outflow end of the medicament buffering module through a medicament inflow end and is connected with the medicament inflow end of the disinfection execution module through a medicament outflow end; the disinfection execution module is used for receiving the medicament sent by the medicament caching module and sending the medicament to the disinfection execution module under the control of the control module;

the medicament inflow end of the medicament caching module is connected with the medicament outflow end of the medicament supplementing module; the medicine adding module is used for receiving the medicine sent by the medicine supplementing module and sending the medicine into the medicine adding execution module under the control of the control module;

the medicament supplementing module is used for connecting the external cooperation end and supplementing medicaments under the control of the control module;

the disinfection execution module is used for disinfecting target substances to be disinfected, the target substances to be disinfected are placed in a container of the disinfection execution module, the medicine is fed into the disinfection execution module through the medicine adding execution module, and the medicine reacts with the target substances to be disinfected to kill microorganisms and germs in a contact manner.

As shown in fig. 2, the control module is a typical industrial control system, and the hardware mainly includes a processor, a memory, a flash memory, an input/output (IO) and a network communication sub-module.

The add-on medication execution module is primarily an electromechanical component. Mainly comprises a controlled pump and a multi-degree-of-freedom mechanical arm with a tip capable of moving in a three-dimensional space. The pump and the mechanical arm are directed by the control module to suck the medicament quantitatively, and the mechanical arm is moved to a designated space position to spray or mix the medicament into a specific object substance.

The sterilization execution module is a container in which the medicament reacts with the substance to be treated. The substance to be treated may be a liquid fluid, a gaseous fluid. The additive agent execution module moves the tip of the mechanism in the container under the instruction control of the control module; the tip is provided with a medicament spray head. The spray form of the medicine can be adjusted to mist, gas and liquid drops according to the requirement. The medicament and the substance to be treated react in the execution module to kill microbes and germs on the surface of the substance or in the fluid in a contact manner.

The disinfection execution module is embedded with a sensor, and the sensor is generally arranged at the position of a fluid outlet. The controller sensor detects the concentration of the medicament in the container in real time.

As shown in fig. 3, the system realizes accurate drug delivery based on data model and sensory control cooperation.

The controller module, the sensor and the dosing action execution module form an accurate medicament adding system which controls the execution mechanism to automatically adjust according to real-time detection data.

In an ideal simplified model, inside the sterilization execution module unit, the fluid to be sterilized enters from the inlet and exits from the outlet. Then, a corresponding relationship is formed among the flow Q of the fluid to be treated, the additive amount M of the medicament and the monitoring value N of the sensor.

Q, M there is a linear relationship; ideally, k is equal to the required amount of medicament per unit fluid flow rate set by the system. Ideally, N ═ k, that is, ideally: and N is M/Q. As shown in the table below.

	Time (t)	Flow (Q)	Additive amount of drug (M)	Detection value (N)
					1	T1	Q1	M1	N1
2	T2	Q2	M2	N2
					3	T3	Q3	M3	N3
…	…	…	…	…
					n	Tn	Qn	Mn	Nn

In actual system operation, two other variables need to be introduced into the data of the system.

Microscopically, when the target fluid and the medicament move and fuse in the cavity, a large amount of diffusion and disturbance can occur randomly, even a certain amount of volatilization can occur, a relatively stable mixed component is formed at an outlet, and the mixed component has a certain deviation from a theoretical value: d.

in addition, in order to ensure the disinfection effect on the fluid, a certain residence time (delta T) of the medicament and the fluid in the reaction cavity is required for carrying out disinfection reaction time.

As shown in FIG. 4, the reaction chamber is designed to have a certain relationship between the volume and the fluid velocity in order to ensure sufficient residence time, and the position of adding the chemical agent is generally located at the fluid inlet and outlet. Therefore, assuming that a specific fluid unit is an undivided whole, and the time at the drug addition position is time T1, the fluid is at the outlet position T2, and T2-T1 are Δ T. That is, the value detected by the sensor at time T should actually correspond to the fluid volume, the medicament volume at (T- Δ T).

After introducing diffusion deviation and time variable, the corresponding relationship between the flow rate, the medicament amount and the detection value is roughly as shown in the following table:

after re-matching, the data records of item n +1 (time T)_(n+1)) The flow rate and the dosage of the medicament are actually equal toItem m +1 (time T)_(n+1)Detected value (N) of + DeltaT_(m+1)) And (7) corresponding.

After the real time dimension change and the deviation variable are introduced, the medicament quantity and the flow still present a basically consistent linear relation: m_(n+1)＝kQ_(n+1)+d。

However, the k value at this time corresponds to the actual detection value: n is a radical of_(m+1)When the time difference of the m term with respect to the n term is Δ T.

In summary, the system is divided into two stages according to whether the running time T is less than Δ T during running, and the system executes the dosing amount by adopting different calculation methods in different stages:

when the system operation time is less than delta T, the system does not consider deviation compensation, and the actual meaning of the detection value of the sensor is not large.

When the system running time reaches delta T, the detection value of the sensor corresponds to the flow and the medicament amount delta T before the current time T.

At t>After Δ T, the system is operated relatively steady, and after introducing time matching and deviation, the difference between the theoretical (set value) k and the measured value N forms a substantially steady data model for the deviation d, where d is N_m–k。

The data of d essentially represents the deviations caused by disturbances and dissipation in the system. This deviation appears statistically as a random fluctuation around the center after the system enters steady state operation. And d deviation within a certain time is taken, and an updated d value is formed after average weighting and is reused for compensating the system operation. As shown in the table below.

As shown in fig. 5, the dosing control flow is after introducing the offset and time reconfiguration.

As shown in fig. 6, in order to ensure the continuous and stable operation of the system, the system forms a continuous drug supply mechanism through a drug buffer module, a drug supplement unit and a set of control management method.

The medicament caching module is a smaller container; the drug refill unit is designed to be a stock of larger amounts of drug or a device capable of producing a given drug on-line.

The medicament caching module caches medicaments scheduled for disinfection in a short time. The container is internally provided with a sensor which detects the residual amount of the medicament in the container and informs the residual amount of the medicament to the control module. When the residual quantity is lower than the set value, the control module sends out an instruction to transfer the medicament from the medicament supplementing device to the medicament caching device.

When the back-up medicament which can be provided in the medicament supplementing unit is lower than the set limit value, the information is fed back to the control module, and the control module processes according to a set strategy to inform a manager to supplement the medicament, or coordinate external supply of the supplement medicament, or start on-line production of the medicament.

It will be understood that modifications and variations can be made by persons skilled in the art in light of the above teachings and all such modifications and variations are intended to be included within the scope of the invention as defined in the appended claims.
