[0038] In a further embodiment, the chassis 300 serves as the robot's mobile carrier, comprising a base plate 303 and a second-layer plate 304 fixedly mounted on top of it. Two sets of drive motors 307 and four sets of omnidirectional wheels 308 are symmetrically mounted on the base plate 303, forming a dual-wheel differential drive system adapted to the smooth surfaces of cleanrooms, enabling precise movement.

The chassis shell 305 has an external anti-collision strip 306 to absorb minor impacts and protect the robot body. For the specific installation structure and method of the chassis 200 in this embodiment, please refer to Chinese Utility Model Patent Application No. 202421849685.2 entitled "A Robot Chassis Structure".

[0039] In a further embodiment, the body 200 is the main structural component connecting the chassis 300 and the air monitoring device 100. The body frame is fixed by a first mounting plate 207, a second mounting plate 208, and a third mounting plate 209 via a first column 210 and a second column 211. The first mounting plate 207 is spaced apart from the second-layer plate 304 of the chassis 300, and the outer shell 212 is fitted over these mounting plates, providing overall protection. The outer shell 212 integrates various interactive and sensing components on its sides, including a first depth camera 201 and a second depth camera 202 for recognizing the surrounding environment during robot movement, an LED strip 203 for displaying the robot's status, and a control screen 204 for easy operation by on-site personnel. The first mounting plate 207 is equipped with a control module 205 (industrial computer) and an electrical control module 206 (circuit control board), which together constitute the robot's main control unit and power management unit. The outer shell 212 also has an inspection port 213 for easy maintenance personnel to inspect the internal components.

[0040] In a further embodiment, the air monitoring device 100 is mounted on the second mounting plate 208 of the fuselage 200 through the base 101. The device includes: a lifting mechanism, and the lifting mechanism includes a lifting electric cylinder 104 driven by a lifting motor 103. The lifting electric cylinder 104 is preferably a two-stage electric push rod. In this embodiment, the model of the lifting electric cylinder can be TYSD095-L800-A5F-H4K2, its maximum stroke can reach 800 mm, the thrust meets ≥100 N, and it has a self-locking device, which can maintain the height accuracy within ±2 mm. The third mounting plate 209 is provided with an opening to cooperate with the lifting electric cylinder 104 to move up and down within this opening.

[0041] In a further embodiment, an installation frame 105 is provided at the top of the lifting electric cylinder 104 for carrying various sensors, including a high-precision particle counter 107, a temperature and humidity meter 108, a high-definition monitoring camera 111, and at least two three-dimensional wind speed monitoring components. Among them, the first wind speed meter 110 is installed on the side of the installation frame 105 through the first bracket 109, and the second wind speed meter 114 is installed on the top of the installation frame 105 through the support frame 112 and the second bracket 113. The first wind speed meter 110 and the second wind speed meter 114 are arranged in a spatial array to realize multi-point and multi-dimensional wind speed measurement, which is beneficial to establish a more accurate aerosol diffusion model. The monitoring camera 111 is fixedly installed on the top of the installation frame 105.

[0042] In a further embodiment, a bellows cover 106 is provided on the outer side of the bottom of the installation frame 105, covering the entire lifting electric cylinder 104, providing a fully enclosed protection to prevent the escape of fine particles generated during the movement of the lifting mechanism. The bottom of the bellows cover 106 contacts and seals with the third mounting plate 209 of the fuselage 200 to ensure that the entire robot meets the use standards of a clean room. The whole machine shell is made of metal material, combined with an electrostatic wheel design, so that the electrostatic parameters of the whole machine are less than the fifth power.

[0043] In a further embodiment, the data processing module inside the air monitoring device 100 has an embedded controller as its core. This module is responsible for synchronously collecting, real-time processing such as outlier filtering and preliminary analysis of data such as temperature and humidity, wind speed, and particulate matter collected by the sensor integration unit. The processed data is transmitted to the control module 205 or the upper computer system through the built-in 5G / WiFi dual-mode module quickly and stably, realizing remote monitoring and linkage analysis. In this embodiment, the data processing module realizing this function is a prior art, so it will not be elaborated here.

[0044] Workflow: After powering on, the robot performs a self-check to confirm that all sensors are functioning normally. While moving along the path, the robot uses data from the ultrasonic radar 302, the first depth camera 201, and the second depth camera 202 to perform real-time obstacle avoidance, ensuring a safe and stable arrival at each preset monitoring point. Upon reaching the monitoring point, the electronic control module 206 controls the lifting motor 103 to drive the lifting cylinder 104, raising the sensor group on the mounting frame 105. According to task requirements, the sensor group is adjusted to the optimal sampling height between 0.8m and 2.5m. At this height, the particle counter 107, thermo-hygrometer 108, first anemometer 110, and second anemometer 114 begin synchronous and continuous data acquisition. Simultaneously, the monitoring camera 111 records real-time video, facilitating remote observation of the environmental conditions by monitoring personnel. The data acquisition unit within the air monitoring device 100 transmits the data to the control module 205 within the robot body 200. The control module 205, as the core processing unit, performs further in-depth analysis on all received sensor data. The control module 205 transmits the analyzed data to the host computer system to generate a visual monitoring report, including historical trends, real-time data, and warnings of exceeding standards. It can also simulate and analyze the airflow organization and particulate matter diffusion path in the cleanroom through the established aerosol diffusion model.

[0045] When the particle concentration or temperature and humidity data monitored by the control module 205 exceeds a preset threshold after being preprocessed and transmitted by the air monitoring device's data acquisition unit, the control module 205 will immediately issue an audible and visual alarm via the light strip 203 and the control panel 204. Simultaneously, the control module 205 automatically generates an abnormal work order and pushes it to the maintenance terminal or the factory MES system via wireless network, notifying relevant personnel to investigate and handle the issue, achieving rapid response.

[0046] Through the above-described structure and working principle, this utility model achieves intelligent, automated, and efficient cleanroom environmental monitoring, effectively solving many problems in the prior art.

[0047] The above embodiments are only for illustrating the technical concept and features of this utility model. Their purpose is to enable those skilled in the art to understand the content of this utility model and implement it. They cannot be used to limit the protection scope of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be covered within the protection scope of this utility model.
