[0002] A cleanroom is a special room that controls the concentration of airborne pollutants (such as suspended particulates and microorganisms) to an appropriate level while also controlling parameters such as temperature, relative humidity, and pressure differential in the indoor environment, thereby reducing the impact on contamination-sensitive work. The widespread use of cleanrooms has benefited products and processes in industries such as aerospace, microelectronics, pharmaceuticals, medical devices, food, and healthcare. With the increasing demand for cleanrooms in the fields of industry, pharmaceutical and food hygiene, and biosafety, higher requirements have been placed on the quality control of clean environments, and cleanroom testing is receiving increasing attention. According to preliminary statistics, there are over 30 domestic testing standards and industry specifications for cleanrooms related to industrial cleanrooms, pharmaceutical cleanrooms and laboratories, medical operating rooms and wards, and biosafety laboratories, some of which are mandatory industry requirements. For example, standards and specifications such as "Clean Room Construction and Acceptance Specifications" GB 50591-2010, "Good Manufacturing Practice for Pharmaceuticals (Revised in 2010)", "9205 Guidelines for Microbial Monitoring and Control in Pharmaceutical Clean Laboratories" in Part IV of the 2015 edition of the "Pharmacopoeia of the People's Republic of China", and "Technical Specifications for Clean Operating Room Construction in Hospitals" GB 50333-2013, stipulate the temperature, relative humidity, static pressure difference, settling bacteria, floating bacteria, dust particle concentration, illumination, noise, wind speed, ventilation frequency, airflow pattern, self-cleaning time, and high-efficiency filter leak detection in clean rooms from the aspects of detection methods and judgment indicators.

[0003] Through practical analysis and summarization of cleanroom inspections, we found that there are numerous inspection items, each with strict location requirements and numerous sampling points and sampling times. Each cleanroom requires repeated inspections of the same items. Inspection instruments are highly specific (one instrument only tests one item), requiring frequent instrument changes during the inspection process. Some of these instruments are handheld, and the uniformity and standardization of inspection personnel significantly impacts the validity and accuracy of inspection data. Typically, a cleanroom production workshop has dozens, sometimes hundreds, of cleanrooms, and a single inspection can take anywhere from a day to several. The repetitive and complex operation of moving and arranging inspection instruments, brackets, and other items is not only time-consuming and labor-intensive, but also impacts the safety, stability, and accuracy of the instruments.
