Description

Technical Field

[0001] The invention relates to the field of measurement technology, and in particular to a multi-dimensional space cleanliness index measurement method based on point planning self-inspection technology. Background Art

[0002] In modern high-tech industries and fields with strict environmental requirements, the maintenance and monitoring of clean spaces are crucial. Take the clean room of semiconductor manufacturing as an example, tiny dust particles may cause defects in chip production and affect product quality; in biosafety laboratories, precise control of environmental parameters such as temperature, humidity, and noise is the key to ensuring experimental accuracy and safety; for the storage environment of Pu'er tea, conditions such as temperature, humidity, and light intensity are directly related to the quality and aging effect of tea.

[0003] Traditional clean space testing methods mainly rely on manual operation. Testers need to carry a variety of instruments, such as thermometers and hygrometers, light meters, anemometers, dust particle counters, etc., and measure one by one according to the pre-set measurement points. During the measurement process, not only is it necessary to record data manually, but the operation is cumbersome and inefficient. Since manual operation is greatly affected by subjective factors, different testers have different measurement techniques and reading habits, which can easily introduce human errors, making it difficult to ensure the accuracy and consistency of the measurement results.

[0004] In addition, manual measurement also has many inconveniences and safety hazards. In some clean spaces with strict restrictions on the number of people entering (such as high-grade clean rooms and specific biosafety laboratories), the number of people entering the measurement area at a time is generally not more than 2, and they must wear heavy clean clothes, which not only increases the difficulty and time cost of operation, but also makes the testers feel uncomfortable and affects work efficiency. Some measurement points may be located at high altitudes or in difficult-to-reach locations, and testers need to use climbing equipment to measure, which undoubtedly increases safety risks. For example, when using a handheld anemometer to measure high-altitude wind speed, the tester needs to stretch his arms as much as possible to keep the measuring head away from the body to reduce personal interference, which is extremely unsafe when working at high altitudes.

[0005] Although there are some remote-controlled test equipment on the market, these devices can usually only carry a single instrument and cannot measure multiple environmental parameters at the same time. Moreover, most of these devices can only work at a fixed height, which makes it difficult to meet the testing needs of clean spaces at different heights. With the development of the economy and the continuous improvement of regulatory requirements, the number of industries that need to perform clean space measurements is increasing, and the measurement workload has increased significantly. Traditional measurement methods can no longer meet the industry's urgent needs for efficient, accurate and safe clean space testing methods.

[0006] In terms of relevant standards and regulations, such as GB50073-2013 "Cleanroom Design Specifications", there are clear requirements for the measurement and control of parameters such as temperature, humidity, light intensity, noise, wind speed and suspended particle count in cleanrooms; Yunnan Province's local calibration specification "Pu'er Tea Storage Environment Monitoring Parameter Test Specifications" also stipulates the monitoring of various parameters of Pu'er tea storage environment. However, the existing measurement technology and equipment are difficult to fully meet the requirements of these specifications, and there is an urgent need to improve and optimize the measurement equipment and methods.

[0022] 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 described embodiments 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 creative work are within the scope of protection of the present invention.

[0023] The present invention proposes a multi-dimensional space cleanliness index measurement method based on point planning self-inspection technology, comprising the following steps: Use a fully automatic trolley equipped with a total station to conduct all-round measurement of the measured space, and calculate the measurement results according to relevant specifications through a pre-set program to obtain the specific location coordinates of the detection points; With the help of laser point cloud technology and PTK positioning system installed on the fully automatic vehicle, the fully automatic vehicle is guided to reach each inspection point; A variety of sensors are integrated on an automatically retractable support rod. When the fully automatic vehicle reaches the measuring point, the length of the telescopic rod is automatically adjusted according to the measuring height, so that the sensor is at the correct measuring position, and the temperature, humidity, noise, wind speed, light intensity, and number of dust particles in the environment are measured at the same time; Using wireless transmission technology, the measurement results are transmitted to the background terminal in real time.

[0024] The total station is used to obtain spatial dimension information, and its measurement data is used as the basic data for calculating the position coordinates of the detection points. The measurement accuracy of the total station meets the requirements of relevant clean space measurement specifications.

[0025] Laser point cloud technology is used to construct a three-dimensional spatial model to assist the PTK positioning system in more accurately determining the moving path and detection point positions of the fully automatic vehicle. The scanning accuracy and resolution of laser point cloud technology can meet the measurement requirements of different clean spaces.

[0026] The PTK positioning system achieves centimeter-level positioning accuracy by receiving satellite signals and ground base station signals, ensuring that the fully automatic vehicle can accurately navigate to the inspection point and update the location information in real time during movement.

[0027] The automatically retractable support rod is equipped with an electric drive device, which can quickly and smoothly adjust the length according to the preset height command. The material and structure of the telescopic rod ensure stability and reliability in different environments, avoiding interference with sensor measurements.

[0028] Various sensors include temperature and humidity meters, light meters, sound level meters, anemometers and dust particle counters. The measurement range and accuracy of each sensor meet the corresponding clean space measurement standards, and each sensor is independent and works together to ensure the accuracy of simultaneous measurements.

The data transmission delay meets the timeliness requirements of detection, and it has data encryption function to prevent data leakage.

[0030] The background terminal is integrated with data analysis software, which can receive data transmitted by various sensors and analyze, calculate and compare key indicators such as temperature and humidity, wind speed and the number of dust particles distributed in the space.

[0031] The data analysis software is equipped with a directional judgment mechanism and a threshold mechanism. The directional judgment mechanism is used to analyze and calculate key indicators, and the cleanliness level of the space is qualitatively evaluated based on the threshold mechanism. The results are then displayed intuitively in the form of a report on the terminal display.

[0032] The data analysis software supports external printers so that users can print paper test reports as needed, and the report format complies with relevant industry specifications and standards.

[0033] This method integrates the total station and laser point cloud technology with the PTK positioning system and multi-source data acquisition channels, and can automatically scan the size of the measured space. Through background calculation, the specific location of the measurement point is obtained, and it automatically navigates to the measurement point. After the telescopic rod rises to the predetermined height, each sensor starts the measurement operation. At the same time, the measurement results will be transmitted to the background terminal in real time, and the user can view the various test results in real time or print them on the background terminal display. The overall architecture of the method and its corresponding function implementation are described as follows Figure 1 As shown; In addition, in order to respond to environmental protection policies, quickly generate test reports and realize intelligent paperless operations, the present invention integrates a set of data analysis software based on the above method and its carrier platform.

In addition, the software also supports external printers so that users can print paper reports. At the same time, by setting a threshold mechanism, the system can qualitatively evaluate the cleanliness level of the space according to preset standards. The calculation principle of space cleanliness level division is as follows Figure 2 shown.

[0034] This multi-dimensional space cleanliness index measurement method based on point planning self-inspection technology uses a fully automatic trolley equipped with a total station to conduct all-round measurement of the measured space, and uses a pre-set program to calculate the measurement results according to relevant specifications to obtain the specific location coordinates of the detection point.

The mobility and flexibility of the fully automatic trolley are used to improve efficiency, and it can be quickly deployed to multiple detection points to achieve simultaneous monitoring of large areas or multiple points, greatly reducing manpower and time costs.

[0035] By integrating various required sensors on the automatically retractable support rod, when the fully automatic trolley arrives at the measuring point, the length of the telescopic rod can be automatically extended or shortened according to the measuring height, so that the sensor is at the correct measuring position. This enhances timeliness and comprehensiveness, and can fully detect the temperature and humidity, noise, wind speed, light intensity, and dust particle count in the environment at one time, solving the problem of being unable to detect at one time during manual measurement; simplifying the operating process, optimizing the user interface and operating process of the fully automatic trolley-mounted equipment, reducing the skill requirements for operators, and improving the ability to respond quickly in emergency situations.
