[0001] The invention relates to the technical field of ultraviolet sterilization lamps, and in particular to an ultraviolet sterilization lamp group with a joint power output adjustment function. Background Art

[0002] Ultraviolet sterilization lamps are commonly used disinfection and sterilization equipment, used in hospitals, industries and other disinfection fields.

[0003] The essence of ultraviolet rays is radiation. During long-term exposure, it will not only cause damage to the human body, but also cause varying degrees of damage to equipment and instruments. It should be noted that for disinfection sites, if the disinfection time is too long, it will aggravate the degree of damage to related equipment in the site. If the disinfection time is too short, the disinfection effect in the site will also be reduced. In addition, when the ultraviolet lamp is turned on, people need to be prohibited from entering the disinfection site, and it is difficult to grasp the disinfection process in real time. Related problems will then arise due to the disinfection time being too long or too short. This application proposes a solution. Summary of the invention

[0004] The purpose of the present invention is to provide an ultraviolet sterilization lamp group with a joint power output adjustment function. According to the disinfection principle of ultraviolet lamps, since they are essentially radiation, they will not only cause different hazards to the human body but also to related instruments and equipment. The opening time (disinfection time) of the ultraviolet lamp is too long / too short, which will affect the disinfection effect. However, during the disinfection period, people need to be completely prohibited from entering the disinfection site, making it difficult to grasp the disinfection time in real time.

[0005] The object of the present invention can be achieved by the following technical scheme: an ultraviolet sterilization lamp group with a row power output adjustment function is adopted, comprising an environmental base layer, a detection assembly and an ultraviolet lamp body, wherein the ultraviolet lamp body and the detection assembly are linearly and equidistantly arranged along the width or length direction of the environmental base layer, and a control assembly is installed outside the environmental base layer;

[0006] The control assembly includes a power supply assembly for controlling the output power of the ultraviolet lamp body and a receiving assembly for receiving monitoring data in the detection assembly, and a master control system associating the ultraviolet lamp body and the detection assembly is established in the control assembly. In the master control system, the output power and monitoring data of the environment inside the base layer are obtained, and the output power of one or more ultraviolet lamp bodies is reversely adjusted again.

[0007] It is further configured as follows: the detection assembly is installed on the ground of the environmental base layer, the ultraviolet lamp body is composed of a spherical lamp head and a support rod base, and the height of the ultraviolet lamp body is equal to half of the height of the environmental base layer.

[0008] It is further configured as follows: the master control system consists of a data integration unit, a data analysis unit and a space interaction analysis unit, wherein the integration unit is used to record the output power of the ultraviolet lamp body and the monitoring data in the detection assembly, and the output power and the detection data are represented by Pn and Cn respectively.

[0009] It is further configured as follows: the detection data Cn is used to represent the real-time concentration of ozone of the ultraviolet lamp body during sterilization.

[0010] It is further configured as follows: based on the output power and detection data in the integrated unit, a dynamic environment curve is established in the data analysis unit with Cn and the working time t, Cn is used as the Y-axis in the dynamic environment curve, and the working time t of the ultraviolet lamp body is used as the X-axis in the dynamic environment curve, and i represents the number of detection assemblies set, and the detection assemblies are numbered with i, i is a positive integer, and a real-time curve corresponding to the detection assembly is set in the dynamic environment curve.

[0011] It is further set as follows: in the dynamic environment curve, the self-test period point T is established again according to the working time t m , and the self-test period point T m Substitute it into the real-time ozone concentration Cn to get C Tm , C Tm- , and establish the calculation method of the working level of the associated ultraviolet lamp body, specifically expressed as C Tm -C Tm- / C Tm- =K m , C Tm Used to indicate the self-test period point T m The real-time ozone concentration in the m Input into the spatial interaction unit.

[0012] It is further configured that: the spatial interaction unit is based on the data analysis unit, wherein m is a positive integer greater than, and at a single self-check period point T m The maximum, minimum, initial and end values ​​of the real-time ozone concentration are marked in Represent it, and generate the associated working level K by matching the maximum value with the minimum value, the initial value with the end value m The calculation methods are expressed as Among them and Respectively represent the working levels obtained in the two coordination methods.

[0013] It is further set as follows: In the spatial interaction unit, according to Set the first-level intermediate threshold A and the second-level intermediate threshold B respectively, B is less than and greater than, A is greater than and less than B, and perform the following state analysis in the spatial interaction unit:

[0014] State 1: If the calculated value in the detection assembly at each position If both are less than A, it means that the UV sterilization effect in the overall environment base has reached a critical state, and the UV lamp body stops operating;

[0015] State 2: If the local position If the two values ​​are less than A, mark the number i of the detection assembly at that location, and call the four detection assemblies adjacent to number i at the same time, and synchronously obtain the results of the four detection assemblies Two values, if the four detection assemblies If both values ​​are also less than A, the corresponding ultraviolet lamp bodies of the four detection assemblies and the detection assembly numbered i will stop running;

[0016] State 3: If the local position Two values ​​are less than A, and the detection assembly in four adjacent positions obtains Two values ​​are greater than A and less than B, when the corresponding number i in the detection assembly calculated When one or two of the values ​​are less than B, the four ultraviolet lamps corresponding to the number i are marked, and the output power of one or more of the ultraviolet lamps is reduced, or one or more of the ultraviolet lamps are directly stopped.

[0017] The present invention has the following beneficial effects:

[0018] 1. The present invention is different from conventional ultraviolet sterilization methods in that the height and position of the ultraviolet lamp body are further set according to the environmental base of the application site. The essence of the present invention is that the spherical lamp head in a "suspended" state can perform global 360° radiation sterilization and provide a comprehensive sterilization process. However, the key is to avoid the occurrence of dead angles or overlapping positions during the ultraviolet sterilization process, which may affect the sterilization effect.

[0019] 2. Combined with the above content, it is explained again that: during the continuous sterilization working time, the characteristics of ultraviolet rays themselves are used again. Because the air in the closed space is continuously irradiated by ultraviolet rays and ionized into ozone, a detection unit composed of an ozone concentration detector is further added. Therefore, during the specific operation period, the overall sterilization process is integrated and analyzed with the real-time ozone concentration. The sterilization effect in the environmental base is fed back with the working level. When the fluctuation degree of ozone concentration is reduced or even no fluctuation is achieved, it means that the overall sterilization effect has reached a relatively good state, and the sterilization effect can be maintained by reducing the output power of the ultraviolet lamp itself or turning off the ultraviolet lamp.

[0026] The technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0027] Embodiment 1: Regarding the disinfection principle of ultraviolet lamps, since they are essentially radiation, they will not only cause different hazards to the human body but also to related instruments and equipment. The opening time (disinfection time) of the ultraviolet lamp is too long / too short, which will affect the disinfection effect. However, during the disinfection period, it is necessary to completely prohibit people from entering the disinfection site, and it is difficult to grasp the disinfection time in real time. The following technical solutions are proposed:

[0028] Reference Figures 1 to 4 The ultraviolet sterilization lamp group with a row power output adjustment function in this embodiment includes an environmental base layer 1, a detection assembly 4 and an ultraviolet lamp body 3. The ultraviolet lamp body 3 and the detection assembly 4 are linearly and equidistantly arranged along the width or length direction of the environmental base layer 1, and a control assembly 2 is installed outside the environmental base layer 1;

[0029] The control assembly 2 includes a power supply assembly for controlling the output power of the ultraviolet lamp body 3 and a receiving assembly for receiving monitoring data in the detection assembly 4, and a master control system associating the ultraviolet lamp body 3 and the detection assembly 4 is established in the control assembly 2. In the master control system, the output power and monitoring data inside the environmental base layer 1 are obtained, and the output power of one or more ultraviolet lamp bodies 3 is reversely adjusted again. The detection assembly 3 is installed on the ground of the environmental base layer 1. The ultraviolet lamp body 3 is composed of a spherical lamp head 301 and a support rod base 302, and the height of the ultraviolet lamp body 3 is equal to half the height of the environmental base layer 1.

[0030] Working principle: The principle of ultraviolet sterilization is to destroy proteins during continuous irradiation. The environmental base layer 1 in the present invention is mainly used to represent the indoor environment. Taking the sterile room in the hospital as an example, in the process of regular ultraviolet sterilization of the sterile room, firstly, a number of ultraviolet lamp bodies 3 are arranged according to the size of the sterile room itself, and a detection assembly 4 is also arranged around the middle position of the ultraviolet lamp bodies 3 at four adjacent positions. Finally, after the sterile room is sealed, the power supply in the control assembly 2 provides power to each ultraviolet lamp body 3 to generate ultraviolet rays. This part is the basic principle of conventional ultraviolet sterilization;

[0031] It should be noted that when the closed space is continuously irradiated with ultraviolet rays, non-uniform ions will be generated around the rays, which will ionize the oxygen molecules in the air and then convert them into ozone. This conversion process not only occurs in the area directly irradiated by the ultraviolet lamp, but also because ozone is a strong oxidant, it has the advantage of no dead angle for disinfection and can diffuse evenly in a relatively sealed environment to achieve the purpose of disinfection and sterilization. Therefore, the essence of the detection unit 4 in the present invention is an ozone concentration detector. Because the density of ozone is much greater than that of air, ozone sinks under normal atmospheric pressure, which is convenient for the ozone concentration detector to perform real-time monitoring.

[0032] Therefore, the basic principle of the present invention is to reversely regulate the output power of each ultraviolet lamp body 3 based on the monitoring data obtained by each detection unit 4 to avoid over-operation of the ultraviolet lamp body 3, which would cause damage to some instruments in the environmental base layer 1.

[0033] Embodiment 2: This embodiment is to optimize the structure of the ultraviolet lamp body:

[0034] The essence of the ultraviolet lamp body 3 in this embodiment is still mainly a lamp head that emits ultraviolet rays, but the key is to limit the spherical lamp head 301 in the ultraviolet lamp body 3, the purpose of which is to ensure that the ultraviolet rays diffuse 360° outward from the spherical lamp head 301, specifically because the effective sterilization range of ultraviolet rays is directly related to its output power, and a sterilization process without dead angles can be carried out in multiple places through a 360° radiation mode;

[0035] It is further explained that: if the height of the environmental base layer 1 is 3.02m, then the total length of the entire ultraviolet lamp body 3 is 1.51m, or slightly less than 1.51m, but the output power of the ultraviolet lamp body 3 needs to be increased so that the diameter of the effective sterilization range of the ultraviolet lamp body 3 is close to 1.51m. This part is similar to the rough calculation method between the current ultraviolet lamp output power / room volume, and is not explained in detail in the present invention. The key purpose of this embodiment is to perform 360° radiation sterilization with a "suspended" spherical lamp head 301.

[0036] Embodiment 3: The overall process is described again in conjunction with Embodiment 1, and includes the following related contents:

[0037] S1: The master control system is composed of a data integration unit, a data analysis unit and a spatial interaction analysis unit, wherein the integration unit is used to record the output power of the ultraviolet lamp body 3 and the monitoring data in the detection assembly 4, and Pn and Cn are used for this, wherein n is mainly used to indicate the number of ultraviolet lamp bodies 3, and is numbered according to the setting position of the ultraviolet lamp body 3, and Cn mainly indicates the real-time ozone concentration of the ultraviolet lamp body 3 during sterilization;

[0038] S2: Combined with the sterilization principle of the ultraviolet lamp body 3, the environment base layer 1 is in a relatively closed state, the air inside it is in a relatively low flow rate or even no flow state, and ozone is continuously generated inside the environment base layer 1 when the ultraviolet rays are continuously irradiated. For this, Cn is in a relatively variable value. In the data analysis unit, a dynamic environment curve is established with Cn and working time t, and Cn is used as the Y-axis in the dynamic environment curve, and the working time t of the ultraviolet lamp body 3 is used as the X-axis in the dynamic environment curve. What is explained in the data analysis unit is: taking the disinfection time of a conventional sterilization lamp as an example, 1h is used as the total sterilization time. However, in the above-mentioned dynamic environment curve, the specific number in the dynamic environment curve is determined according to the number of each inspection assembly 4. If there are i detection assemblies 4 in the environment base layer 1, then there are i real-time curves in the dynamic environment curve. i can also be used as the number of the detection assembly 4, so i is a positive integer;

[0039] S3: Combined with the dynamic environment curve again for explanation, in which the self-check cycle point T is established again according to the working time t m , its essence is: each ultraviolet lamp body 3 starts to run until the working time reaches T m After that, the real-time ozone concentration at the corresponding self-test period is obtained and expressed as (C Tm -C Tm-1 ) / C Tm-1 =K m , where K m Mainly used for corresponding to the working level of each ultraviolet lamp body 3 in the detection assembly 4, where C Tm Used to indicate the self-test period point T m Real-time ozone concentration in the

[0040] S4: The spatial interaction unit uses the analysis process in the data analysis unit to obtain the following content again:

[0041] S4-1: In the first self-test cycle point, because the ultraviolet lamp body 3 has just been started, the ozone concentration in the environmental base layer 1 is approximately 0, so the first self-test cycle point is not considered, so m is a positive integer greater than 1. Specifically, the working level is calculated from the second cycle, so that in the second self-test cycle point, the self-test cycle point T is directly obtained first. m The maximum value, minimum value, initial value and end value of the real-time ozone concentration in the working series are combined into the calculation process, which specifically includes substituting the maximum value and minimum value, initial value and end value into the working series. Represents the maximum value, minimum value, initial value and end value mentioned above, so that we can get as well as Among them Possibly Equal, which is directly ignored in this embodiment. The key is to obtain different real-time ozone concentrations. and

[0042] S4-2: Combined with the content of S4-1, it is explained that because and It is based on the monitoring data in the detection assembly 4 in the corresponding position, so an integrated analysis is performed through spatial interaction analysis, specifically for and The first-level intermediate threshold A and the second-level intermediate threshold B are set respectively. B is less than 1 and greater than 0, and A is greater than and less than B. It can even be understood that A is close to 0, as follows:

[0043] State 1: If the monitoring data detected by the detection assembly 4 at each position is substituted into and Calculate and get, If both values ​​are less than A, it means that the ultraviolet sterilization effect in the overall environment base layer 1 has reached a critical state, because the oxygen in the middle of the area is ionized by ultraviolet rays to generate ozone. If the ultraviolet lamp continues to irradiate, the ultraviolet rays will mainly affect related instruments or do useless work, so that each ultraviolet lamp body 3 stops operating;

[0044] State 2: Local position If both values ​​are less than A, refer to Figure 2 To illustrate, mark the number i of the detection assembly 4 at this location, and simultaneously call the four detection assemblies 4 adjacent to the number i, and synchronously obtain the four detection assemblies 4 obtained Two values, if the four detection assemblies 4 If both values ​​are also less than A, the corresponding four detection assemblies 4 and the ultraviolet lamp body 3 in the detection assembly 4 with number i stop running;

[0045] State 3: Combined with state 2, if the detection assembly 4 in four adjacent positions obtains Two values ​​are greater than A and less than B. The calculation method of the two values ​​is as follows: When one or both of the values ​​are less than B, the four ultraviolet lamps 3 corresponding to the number i are marked. The output power of one or more of the ultraviolet lamps 3 can be reduced, or even one or more of the ultraviolet lamps 3 can be directly stopped. The purpose is to avoid additional impact caused by over-operation of the ultraviolet lamps.

[0046] In summary: according to the basic principle of ultraviolet sterilization, its continuous radiation process will cause ozone to be generated in the closed space. The basic technical point in the present invention is to first limit the setting height and setting position of the ultraviolet lamp body. Its essence is to carry out a global 360° radiation sterilization process by coordinating the setting with the environmental base layer. The key technical point of the present invention is that during the continuous sterilization working time, the ozone concentration in the local position is combined to give real-time feedback on the sterilization effect of the ultraviolet lamp in the corresponding position. Its essence is that there is an upper limit to the ionization of air into ozone. When the fluctuation degree of ozone concentration is reduced or even no fluctuation is reached, it means that the overall sterilization effect has reached a relatively good state, and the sterilization effect can be maintained by reducing the output power of the ultraviolet lamp itself or turning off the ultraviolet lamp.
