Description
Technical Field
The invention relates to the field of food hygiene monitoring, in particular to an uninterrupted monitor and a monitoring system for ultraviolet disinfection effect and a using method thereof.
Background
In order to ensure the food sanitation and safety of the catering industry, the country makes relevant standards, wherein the kitchen in the catering industry is clearly required to be disinfected periodically so as to thoroughly kill infectious and harmful viruses and bacteria, ensure the food safety of consumers and avoid the influence and harm of the infectious viruses on society.
The most commonly used sterilization means at present is ultraviolet lamp sterilization, and related management and use regulations require that the ultraviolet lamp is used as an air sterilization device, air and an operation table should be sterilized before each meal (or each time) is used in a private room, the ultraviolet lamp is used for sterilization, and the ultraviolet lamp should be started for more than 30 minutes … … when no one works, so that the ultraviolet lamp sterilization has higher use frequency and longer time in actual use.
However, the ultraviolet lamp has the service life, if the service life is calculated according to the actual service time, the ultraviolet lamp is inconvenient to record; in addition, the service life of the ultraviolet lamp is influenced by the conditions of ambient temperature, oil stain, dirt and air, so that the service life of the ultraviolet lamp can not be accurately judged by simply recording whether the ultraviolet lamp is in an effective state or not, and therefore, a person monitors the ultraviolet lamp by using an ultraviolet irradiance meter to judge whether the ultraviolet lamp can still work effectively or not.
The ultraviolet probe of the product of the ultraviolet irradiance meter commonly used in the day before is separated from a main controller (reading unit) and connected with the main controller through a data line (cable), an auxiliary device is needed to suspend the probe below an ultraviolet lamp for detection during detection, the ultraviolet probe is required to suspend 1m below the ultraviolet lamp for detection, the use specification refers to the evaluation method and standard of the disinfection and sterilization effect of GB15981-1995, and the second ultraviolet surface disinfection effect evaluation method and standard of the common 30W straight tube type ultraviolet lamp are more than or equal to 70 mu W/cm < 2 >, so that the ultraviolet radiation intensity (at the position of vertical 1 m) of 253.7nm is more than or equal to 70 mu W/cm < 2 >, therefore, during detection, a user hangs the ultraviolet probe, then holds the main controller to leave a detection room, closes a door, and opens the ultraviolet probe by using a switch on the main controller for detection.
However, the hanging mode can block ultraviolet light in a certain area, so that a sterilized workbench below a probe cannot be irradiated by an ultraviolet sterilizing lamp, and thus the ultraviolet lamp cannot be detected while sterilizing, and the state of the ultraviolet lamp is detected by independently arranging time; because of the high-requirement hanging condition, the workbench below the ultraviolet radiation detector is very easy to influence, so that the ultraviolet radiation detector cannot work well, therefore, when the ultraviolet radiation detector is not used for detecting ultraviolet radiation, the ultraviolet radiation detector needs to be folded, when the ultraviolet radiation detector is needed, the ultraviolet radiation detector is hung, the operation procedure is very complex, the operation is very inconvenient, and in general, the ultraviolet radiation detector needs to be paved by more professionals; in addition, since the user uses the ultraviolet irradiance meter according to experience, it is very likely that the ultraviolet lamp has been found to have exceeded the service life when it is used for a certain time, and the delay is long, it is very important to develop an apparatus capable of continuously detecting the state of the ultraviolet lamp.
