Description

Technical Field

[0001] This utility model belongs to the field of product testing technology, specifically relating to a climate and environmental effect factor collection device, which can be used to monitor and collect the impact of climate and environmental factors on products. Background Technology

[0002] With increasingly stringent requirements for product quality, new demands are being placed on assessing the environmental adaptability and reliability of products. Real-time monitoring of products under various climatic and environmental influences, followed by analysis and processing of the monitoring data, is a crucial foundation for improving the scientific rigor and accuracy of testing and evaluation.

[0003] Most existing climate and environmental data acquisition devices only collect conventional climate and environmental parameters such as temperature, humidity, and atmospheric pressure. Many of these devices are fixed in one location and cannot be used with the product. This not only fails to accurately reflect the impact of the atmospheric environment on the product, but also makes the sensors susceptible to damage, especially in harsh environments, and prevents real-time monitoring of product corrosion.

[0004] Patent document CN 208588833 U discloses a “retractable solar-powered miniature automatic weather station”, which includes a data acquisition box, a cover plate, a lifting rod, a cross arm, and a bracket. The device can monitor temperature, humidity, light intensity, wind speed and direction, and air pressure in agricultural meteorological conditions. Although it is portable, it cannot be installed and fixed on the product surface for data collection, and its reliability is not high when used in harsh outdoor environments. It also lacks monitoring for corrosion.

[0005] Patent document CN 105158820 A discloses a "portable multi-meteorological element data acquisition system," which includes a data storage module, a low-temperature battery, a solar panel, an aviation docking connector, a waterproof and insulated acquisition box, and meteorological sensors. While this system offers some protection against harsh environments, it is primarily used for collecting conventional meteorological elements and cannot monitor product corrosion. Utility Model Content

[0006] The purpose of this invention is to provide a portable climate and environmental effect factor acquisition instrument to address the shortcomings of the prior art, thereby improving the reliability of the acquisition device in harsh outdoor environments, making it easy to fix on any surface or inside a product, and enabling real-time acquisition and monitoring of climate and environmental effect factors, including corrosion current.

[0007] To achieve the above objectives, this utility model provides a portable climate and environmental effect factor acquisition instrument, comprising an acquisition device and an acquisition host, which are connected by a connecting cable, characterized in that:

[0008] The data acquisition host includes fastening screws, a top cover, a circuit board, a housing, and a base. The housing is tightly connected to the top cover by fastening screws and fixed above the base. Its surface is provided with an electrical connector using an aviation plug, and the circuit board is fixed inside. The base has positioning through holes at its four corners and a square groove at its bottom, with a strong magnet installed in the square groove.

[0009] The data acquisition device includes a sensor group and a sensor housing. The sensor group includes a temperature and humidity sensor, an atmospheric pressure sensor, a solar radiation sensor, and a corrosion sensor. The atmospheric pressure sensor is fixed inside the sensor housing, while the temperature and humidity sensor, the solar radiation sensor, and the corrosion sensor are fixed on the surface of the sensor housing.

[0010] Furthermore, the fastening screws tightly connect the housing and the housing cover, and the electrical connector adopts an aviation plug, including a data acquisition interface and a communication interface. The data acquisition interface is located on the front of the housing, and the communication interface is located on the side of the housing. All connection gaps are filled with epoxy resin.

[0011] Furthermore, the base has positioning through holes at its four corners and a square groove at the bottom, with a strong magnet inside the square groove, for mounting and fixing the data acquisition host to any surface or interior of the product by means of bolt fastening or magnetic adsorption.

[0012] Furthermore, the corrosion sensor in the acquisition device can collect the corrosion current of the environment in which the product is located, and monitor the corrosion status of the product in real time.

[0013] Compared with the prior art, this utility model has the following advantages:

[0014] Firstly, the data acquisition host of this utility model has an IP65 protection capability in the working state because the outer shell and the outer shell cover are tightly connected by fastening screws, and the electrical connector adopts an aviation plug and the gaps in the connection are filled with epoxy resin, effectively ensuring the reliability of use in harsh outdoor environments.

[0015] Secondly, because the base has a positioning through hole and a strong magnet, the entire data acquisition device can be firmly fixed on any surface or inside the product, and can collect data on climate and environmental factors along with the product, thus improving the quality of the collected data.

[0016] Thirdly, this utility model adds a corrosion sensor to the sensor group to collect the corrosion current of the product under various climatic environments, which not only improves the ability to collect climatic environmental data, but also ensures the accuracy of subsequent analysis of the impact of climatic environmental factors on product corrosion.

[0021] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0022] This invention is applied to the scenario of collecting climatic environmental effects during product testing. The object of the data collection is the climatic environmental factors during the use of unmanned aerial vehicles (UAVs). During use, UAVs will experience environments such as high temperature, low air pressure, and high humidity. To investigate the impact of environmental factors on their corrosion, a portable and highly reliable data acquisition device is needed to accompany the product to collect and monitor its actual operating environment, and to store the data for subsequent analysis.

[0023] Reference Figure 1 The portable climate and environmental effect factor acquisition instrument provided by this utility model includes an acquisition host and an acquisition device, wherein:

[0024] The acquisition host includes a fastening screw 1, an outer cover 2, a circuit board 3, an outer shell 4, and a base 6. The outer shell 4 is tightly connected to the outer cover 2 by the fastening screw 1 and is fixed above the base 6. An electrical connector 5 is provided on its surface, and the circuit board 3 is fixed inside.

[0025] The outer casing 2 has four LED indicator lights on its surface: communication, storage, charging, and power. The on / off state of the indicator lights is controlled by the circuit board 3 and is used to indicate the status of the device during communication, storage, and charging.

[0026] The base 6 has positioning through holes at its four corners and a square groove at its bottom. A strong magnet 7 is installed in the square groove, which is used to install and fix the main unit to the product surface by means of bolt fastening or magnetic adsorption.

[0027] The data acquisition device includes a sensor group and a sensor housing 9. The sensor group includes a temperature and humidity sensor 10, an atmospheric pressure sensor 11, a solar radiation sensor 12, and a corrosion sensor 13. The atmospheric pressure sensor 11 is fixed inside the sensor housing 9, and the temperature and humidity sensor 10, the solar radiation sensor 12, and the corrosion sensor 13 are fixed on the surface of the sensor housing 9.

[0028] The sensor housing 9 is rectangular in shape, with three mounting holes on its surface. The size of these holes matches the apertures of the temperature and humidity sensor 10, the solar radiation sensor 12, and the corrosion sensor 13, respectively, for fixing the aforementioned sensors. The front of the sensor housing 9 has a transmission interface for transmitting the collected signals to the circuit board 3 via the connecting cable 8. The base on which the sensor housing 9 connects to the temperature and humidity sensor 10 has a connecting hole for allowing the atmospheric pressure sensor 11 to communicate with the outside.

[0029] The electrical connector 5 includes a data acquisition interface and a communication interface. The data acquisition interface is connected to the signal acquisition module 32 and the level conversion module 34 and is located on the front of the housing 4. It is used to collect signals from the data acquisition device and transmit them to the signal acquisition module 32 and the level conversion module 34. The communication interface is connected to the communication module 35 and is located on the side of the housing 4. It is used for communication between the external device and the communication module 35.

[0030] Reference Figure 2 The circuit board 3 includes a central processing unit 31, a signal acquisition module 32, a signal conditioning module 33, a level conversion module 34, a communication module 35, a USB flash drive storage module 36, and a power supply module 37, which are used to receive acquired signals, process signals, store data, and set sampling parameters and sampling intervals; the signal conditioning module 33, the level conversion module 34, the communication module 35, the USB flash drive storage module 36, and the power supply module 37 are all connected to the central processing unit 31;

[0031] The input end of the signal acquisition module 32 is connected to the corrosion sensor 13, and the output end is connected to the signal conditioning module 33. It is used to acquire the signal of the corrosion sensor 13 and output it to the signal conditioning module 33. The conditioning module 33 has an analog-to-digital converter, and the signal is processed and transformed by it before entering the central processing unit 31.

[0032] The level conversion module 34 is connected to the temperature and humidity sensor 10, the atmospheric pressure sensor 11, and the solar radiation sensor 12. It is used to process the data collected by the temperature and humidity sensor 10, the atmospheric pressure sensor 11, and the solar radiation sensor 12 and output signals to the central processing unit 31. Finally, the central processing unit 31 stores all the collected data to the USB flash drive storage module 36, and can set the acquisition parameters and sampling interval through the communication module 35.

[0033] Reference Figure 3 The working principle of this utility model is as follows:

[0034] I. Equipment Preparation Before Data Collection

[0035] Place the data acquisition device in the environment to be tested and fix it to the product surface with a strong magnet on the casing. Set the data acquisition interval to 60 seconds and the continuous data acquisition time to 1 day on the data acquisition host.

[0036] II. Collecting data from the environment to be tested

[0037] Press the start button to power on the sensor and begin collecting data.

[0038] The resistance values ​​of the temperature sensor, humidity sensor, and air pressure sensor change with the temperature, humidity, and air pressure. The above sensors transmit the resistance data to the central processing unit through the level conversion module. The central processing unit converts the resistance data into temperature, humidity, and air pressure data and saves the data to a USB flash drive.

[0039] The silicon photodiode inside the solar radiation sensor generates a proportional current based on the radiation intensity. The current data is transmitted to the central processing unit via a level conversion module. The central processing unit converts the current data into solar radiation intensity data and saves the data to a USB flash drive.

[0040] The interconnected copper and iron sheets inside the corrosion sensor will undergo galvanic corrosion and generate corrosion current under the test environment. The corrosion sensor transmits the corrosion current data to the central processing unit through the signal acquisition module and the signal conditioning module. The central processing unit saves the current data to a USB flash drive.

[0041] The central processing unit records data every 60 seconds according to the set acquisition interval, and stops data acquisition after a full day of continuous acquisition. Operators can determine the device's operating status and battery level by checking the four LED indicators on the main unit's casing: communication, storage, charging, and battery level.

[0042] The effectiveness of this utility model can be further illustrated by the following data collection:

[0043] The data acquisition device is placed in the environment to be tested. The acquisition interval and continuous acquisition time are set on the acquisition host. The device collects parameters of the environment, including temperature, humidity, solar radiation, and corrosion current. The acquired data is processed by the conditioning module and level conversion module before being sent to the central processing unit (CPU). The CPU then stores the data on a USB flash drive. The stored data is then visualized and analyzed to obtain data curves, as shown below. Figure 4 .

[0044] from Figure 4 As can be seen, this utility model can not only continuously collect the temperature, humidity, solar radiation and corrosion current parameters of the test environment, but also intuitively understand the severity of the test environment and the corrosion rate of the product in the environment by collecting the temperature, humidity, solar radiation and corrosion current data of the test environment, thereby helping practitioners to assess the product service life and adjust the product protection strategy.

[0045] The above description is merely a specific example of this utility model and does not constitute any limitation on this utility model. Obviously, those skilled in the art, after understanding the content and principle of this utility model, may make various modifications and changes in form and details without departing from the principle and structure of this utility model, such as changing the shape of the shell, increasing or decreasing the number of sensor groups, etc. However, these modifications and changes based on the concept of this utility model are still within the protection scope of the claims of this utility model.
