Description

Technical Field

[0001] This invention relates to the field of data acquisition, and more particularly to a data acquisition device based on the Internet of Things. Background Technology

[0002] Data acquisition refers to the automatic collection of non-electrical or electrical signals from analog and digital devices under test (DUTs) such as sensors and other devices, and the transmission of these signals to a host computer for analysis and processing. A data acquisition system combines measurement hardware and software products based on a computer or other dedicated testing platform to create a flexible, user-defined measurement system.

[0003] For PM2.5 monitoring and data collection currently available on the market, such as the utility model patent with publication number CN209879725U, it includes a data collector body. A support plate is fixedly installed at the bottom of the data collector body. Two support blocks are fixedly installed at the bottom of the support plate. A threaded rod is rotatably installed on the two support blocks. Two sliders are threaded onto the threaded rod. Support rods are fixedly installed at the bottom of each slider. Arc-shaped plates are fixedly installed at the ends of the two support rods that are close to each other. Arc-shaped pads are fixedly installed on the sides of the two arc-shaped plates that are close to each other. A first pulley is fixedly sleeved on the threaded rod. A housing is fixedly installed on the top of the support plate, and the bottom of the housing is open. A servo motor is fixedly installed on the top of the support plate, and a rotating rod is fixedly installed on the output shaft of the servo motor. This utility model is highly practical, easy to install, and saves time and effort.

[0004] However, in practical use, we found that using only a single sensor for detection can lead to errors if dust or other impurities adhere to the sensor's probe, resulting in low detection accuracy. In addition, the acquisition height of the existing technology cannot be adjusted, which means that the comprehensiveness of the acquisition needs to be improved. Therefore, we need to consider how to solve these problems. Summary of the Invention

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing an Internet of Things-based data acquisition device. During use, this device utilizes two probes for collaborative detection, which greatly improves the accuracy of detection. In addition, the acquisition height is adjustable, which enhances the comprehensiveness of detection.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A data acquisition device based on the Internet of Things includes a limiting plate with an installation opening on its front side and a control box fixedly connected to its lower end; a column located inside the installation opening; a limiting mechanism including an arc-shaped clamping plate vertically disposed within the installation opening, a rubber pad disposed on the left side of the arc-shaped clamping plate, and a screw rotatably connected to the right side of the arc-shaped clamping plate, the right end of the screw penetrating the inner wall of the right side of the installation opening and threadedly connected to the penetrating point, and a crank fixedly connected to the right side of the screw; an acquisition module including a horizontal plate disposed above the limiting plate, with two acquisition sensors symmetrically fixedly mounted on the upper end of the horizontal plate; and a moving mechanism cooperating with the acquisition module.

[0008] Preferably, the moving mechanism includes a rectangular strip formed on the upper end of the limiting plate, a groove formed on the left side of the rectangular strip, a threaded rod rotatably connected between the upper and lower inner walls of the groove, a slider threadedly connected to the threaded rod, the slider being slidably connected to the inner wall of the groove, the left side of the slider extending to the outside, and the left side of the slider being fixedly connected to the right side of the cross plate.

[0009] Preferably, a connecting plate is fixedly connected to the upper end of the rectangular bar, and a motor is installed on the right side of the connecting plate. The output shaft of the motor extends into the slide groove and is fixedly connected to the upper end of the threaded rod. The motor is a servo motor that can change the direction of rotation.

[0010] Preferably, a guide rod is fixedly connected to the right side of the arc-shaped clamping plate, and two guide grooves are opened on the right side wall of the mounting port. The right ends of the two guide rods extend into the guide grooves and are slidably connected to the inner wall of the guide grooves.

[0011] Preferably, a telescopic bladder is provided between the upper end of the slider and the inner top of the slide groove. The top space of the telescopic bladder is connected to the outside through an air inlet pipe, and an air outlet pipe is connected to the top space of the telescopic bladder. A first one-way valve is installed in the air inlet pipe, and a second one-way valve is installed in the air outlet pipe.

[0012] Preferably, a mounting frame is fixedly connected to the upper end of the limiting plate, and a solar panel is mounted on the upper end of the mounting frame.

[0013] Preferably, a first hollow strip is fixedly connected to the upper end of the left side portion of the solar panel, and a plurality of first air vents are opened on the right side wall of the first hollow strip. A second hollow strip is fixedly connected to the upper end of the horizontal plate, and second air vents are opened on both the left and right sides of the second hollow strip. The two second air vents are respectively facing the two acquisition sensors. The other end of the air outlet pipe is connected to a first branch pipe and a second branch pipe. The other end of the first branch pipe is connected to the first hollow strip, and the other end of the second branch pipe is connected to the second hollow strip.

[0014] Preferably, it further includes an IoT control module, a data comparison module, a remote transmission module, and a terminal display module. The IoT control module is used to control the acquisition module. The data comparison module and the remote transmission module are both integrated in the control box. The data comparison module is used to compare the information acquired by the acquisition module and transmit the processed information to the terminal display module through the remote transmission module.

[0015] Compared with the prior art, the beneficial effects of this invention are as follows:

[0016] 1. Two data acquisition sensors are set up to detect and compare the outdoor PM2.5. When the information collected by the two sensors has a large error, it will be fed back to the acquisition module for secondary acquisition until the error is small. Only then will the processed information be transmitted to the terminal display module through the remote transmission module. This can effectively improve the accuracy of detection.

[0017] 2. The operator can start the motor to drive the threaded rod to rotate, thereby realizing the up and down movement of the slider. The up and down movement of the slider can adjust the height of the data acquisition sensor to adapt to sampling at different heights, thus improving the comprehensiveness of the sampling.

[0018] 3. Each time the slider moves upward, a high-speed airflow is blown out from the first and second air vents, which can clean the solar panel and the sensor probe, thereby ensuring the performance of the solar panel and the sampling accuracy of the sensor. Attached Figure Description

[0034] In one embodiment of the present invention, a telescopic bladder 20 is provided between the upper end of the slider 31 and the inner top of the slide groove 10. The top space of the telescopic bladder 20 is connected to the outside through an air inlet pipe 21, and an air outlet pipe 22 is connected to the top space of the telescopic bladder 20.

[0039] In addition, each time the slider 31 is moved upward, the telescopic bladder 20 is squeezed. After the telescopic bladder 20 is squeezed, the gas will be discharged through the air outlet 22 and discharged from the first branch pipe 8 and the second branch pipe 17. In this way, a high-speed airflow can be blown out from the first air outlet 7 and the second air outlet 18, which can clean the solar panel 5 and the probe of the acquisition sensor 15, thereby ensuring the use effect of the solar panel 5 and the sampling accuracy of the acquisition sensor 15.
