[0002] Ultraviolet lamps have excellent germicidal properties and are widely used in industries such as healthcare, epidemic prevention, food, and pharmaceuticals. In recent years, they have also found their way into the home. To ensure effective germicidal effects, UV lamps must remain on for a certain period of time. Therefore, finding a convenient and quick way to turn UV lamps on and off has become a pressing issue. Furthermore, UV intensity gradually decreases with extended use, making regular monitoring of UV intensity a must.

Figure 1 , turn on the switch when needed, the UV lamp tube works stably, and turn off the switch after work is completed. The disadvantage of this design is that it needs to be manually turned on and off.

[0029] In order to help those skilled in the art better understand the present invention, the following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of the present invention.

[0030] It should be noted that the terms "first", "second", etc. in the specification and claims of the present invention and the above-mentioned drawings are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that the numbers used in this way can be interchanged where appropriate, so that the embodiments of the present invention described herein can be implemented in an order other than those illustrated or described herein. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions. For example, a process, method, system, product or device that includes a series of steps or units is not necessarily limited to those steps or units clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0031] Figure 2 This is a schematic diagram of the structure of a UV lamp monitoring and control device provided according to an embodiment of the present invention, with reference to Figure 2The embodiment of the present invention provides an ultraviolet lamp monitoring and control device, which includes: multiple ultraviolet lamps 10 and a central monitoring platform 20, wherein the multiple ultraviolet lamps 10 are communicatively connected to the central monitoring platform 20; the ultraviolet lamp 10 includes: an intelligent switch 11, a lamp tube 12, a buck-boost module 13, an ultraviolet sensor 14, and a development board 15, wherein the first end of the lamp tube 12 is connected to the neutral line and the buck-boost module 13, the buck-boost module 13 is connected to the ultraviolet sensor 14 and the development board 15 in sequence, and the development board 15 is communicatively connected to the central monitoring platform 20, the lamp tube 12 It is used to emit ultraviolet rays for disinfection, and the buck-boost module 13 is used for voltage conversion and powering the ultraviolet sensor 14. The ultraviolet sensor 14 is used to convert the intensity of ultraviolet rays sensed and monitored in real time into a voltage signal and send it to the development board 15. The development board 15 is used to generate an alarm message and send it to the central monitoring platform 20 when the voltage signal exceeds a preset threshold. The fourth end of the lamp tube 12 is connected to the development board 15 and the smart switch 11, and the smart switch 11 is connected to the live wire. The development board 15 and / or the central monitoring platform 20 are also used to control the smart switch 11 to perform timed switching and countdown.

[0032] Specifically, in addition to the existing circuit design, a UV sensor 14 is connected in parallel to the UV lamp. This UV sensor 14 monitors the UV intensity emitted by each UV lamp's tube 12 in real time. Abnormal conditions can be promptly reported via the development board and central monitoring platform 20, prompting relevant personnel to understand and address them, thus avoiding failure to achieve the desired sterilization effect due to abnormal activation or insufficient UV intensity. At the same time, the traditional switch is replaced with an intelligent switch 11, which features a timer and countdown mode. The timer can be set through the development board 15 and / or central monitoring platform 20 based on usage, automatically turning the switch on or off as needed, eliminating the need for manual switching.

[0033] The UV lamp monitoring and control device is centered around a UV sensor 14, along with components such as a buck-boost module 13 (the UV sensor 14 can operate at a voltage range of 3V-6V, requiring the buck-boost module 13 to step down the mains voltage), and a development board 15. These components sense and transmit UV intensity information. Changes in the UV intensity emitted by the lamp 12 can cause changes in the photocurrent. The UV sensor 14 can monitor the UV lamp's current and monitor the UV intensity in real time. The UV sensor 14 converts the real-time sensed UV intensity into a voltage signal and sends it to the development board 15. When the voltage signal exceeds a preset threshold, the development board 15 promptly sends an alarm to the central monitoring platform, alerting personnel to replace the UV lamp. This prevents substandard disinfection due to insufficient UV intensity, thus failing to achieve the intended purpose.

[0034] The development board 15 can be connected to Wi-Fi or Bluetooth to communicate with the central monitoring platform 20. When the voltage signal sent by the UV sensor 14 exceeds a preset threshold, the development board 15 generates an alarm message and sends it to the central monitoring platform 20. The development board 15 can be installed on the UV lamp base.

[0035] The central monitoring platform 20 can be a self-developed platform or a third-party platform. Each ultraviolet lamp is numbered to realize the functions of real-time viewing of the light emission of the ultraviolet lamp tube, setting timed switches according to needs, real-time monitoring of ultraviolet intensity, and abnormal prompt alarms (abnormal alarms: abnormal switch alarms, ultraviolet intensity abnormal alarms, etc. can be set according to needs).

[0036] According to the technical solution of the embodiment of the present utility model, the intelligent switch can set the timer switch period according to the usage situation, automatically open or close as needed, and save the time of manual switch; the ultraviolet sensor can monitor the switch status, ultraviolet intensity, etc. of each ultraviolet lamp in real time. In the event of an abnormality, the development board can promptly alarm the relevant person in charge through the central monitoring platform to understand and deal with it, so as to avoid the ideal sterilization effect not being achieved due to abnormal opening or insufficient ultraviolet intensity. By numbering each ultraviolet lamp, each ultraviolet lamp can be turned on and off independently and automatically, reducing the difficulty of measuring the intensity of each ultraviolet lamp tube, monitoring the ultraviolet intensity in real time and alarming in the event of an abnormality, so as to effectively achieve the sterilization effect. In summary, the present utility model solves the problem that the existing ultraviolet lamps need to be manually turned on and off, and measuring the intensity of each ultraviolet lamp tube is too complicated and cumbersome, and cannot effectively achieve sterilization.

[0038] Continue to refer Figure 3 Optionally, the operational amplifier U1 may be a model of SGM8521.

[0039] Specifically, when LED D1 is exposed to ultraviolet light, UV sensor 14 generates a current proportional to the UV intensity. This current is amplified by the SGM8521 operational amplifier and converted into a voltage signal. If the voltage signal exceeds a preset threshold, the development board generates an alarm and sends it to the central monitoring platform, prompting relevant personnel to investigate and address the issue, prompting prompt replacement of the UV lamp. This prevents substandard disinfection due to insufficient UV intensity, thereby failing to achieve the desired disinfection goal.
