Description

Technical Field

[0001] The present invention relates to the field of laboratory testing technology, and in particular to an unmanned laboratory testing management and control system. Background Art

[0002] In the field of scientific research and industrial testing, laboratories undertake important tasks such as verifying theories, optimizing product performance, and exploring new materials. However, during laboratory testing, a series of unexpected situations often plague researchers, which may not only lead to experimental failures, but also waste a lot of time and resources, and even damage experimental equipment.

[0003] Unexpected situations during laboratory testing include control part crashes caused by software failures, hardware aging, or electromagnetic interference, which results in the inability to save and upload data collected by experimental instruments, leading to the loss of experimental data. On the other hand, the laboratory environment is complex, and it is difficult to detect abnormal temperatures in time during experimental testing.

[0004] In order to avoid the impact of these unexpected conditions on the experiment, the laboratory usually uses personnel on duty to monitor the experimental process. The on-duty personnel need to pay close attention to the operating status of the experimental instruments and the changes in the experimental environment, so that they can take quick measures to deal with abnormalities. However, this manual on-duty method has obvious disadvantages: 1. The on-duty personnel need to be highly vigilant at all times, which not only consumes a lot of physical strength and energy, but also may lead to a decrease in work efficiency. At the same time, due to the limited attention of people, it is difficult to ensure that the experimental process is monitored without omissions for a long time; 2. Error-prone: Even if the on-duty personnel are very serious and responsible, it is difficult to completely avoid work negligence. When the experimental process is complicated and there are many monitoring points, the on-duty personnel may not be able to detect and handle all abnormalities in time. In addition, due to the limited judgment and reaction speed of people, even if abnormalities are found, they may not be able to make correct decisions in a short time.

[0005] In summary, although the existing personnel monitoring method in the laboratory testing process can reduce the occurrence of unexpected situations to a certain extent, its shortcomings are also very obvious. Therefore, finding a more efficient, accurate and economical monitoring method has become an urgent need in the laboratory testing process. Summary of the invention

DETAILED DESCRIPTION

[0040] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0041] The laboratory unmanned testing control system provided by the present invention includes the following working modes.

[0042] Working mode 1 (installation mode):

[0043] Figure 8 A schematic cross-sectional structure diagram of a track 11 disclosed in an embodiment of the present invention is shown, wherein the self-driving hanging track structure 1 comprises a track 11 installed on a laboratory ceiling 4 .

[0044] Among them, the structure of the track 11 includes a straight line shape, a closed curve shape, a circular ring shape, an elliptical shape, etc. The track 11 structure is arranged according to the distribution of the laboratory test area. For example, the laboratory test area is provided with several experimental tables 5 at different positions, and experimental instruments 6 are arranged on the experimental tables 5. When installing the track 11, the range and structure of the track 11 are determined according to the position of each experimental table 5 so that it can drive the capture control terminal 3 to cover all the experimental instruments 6.

[0045] A driving device 12 is provided on the track 11, and the driving device 12 includes a mounting frame 12a, which is arranged inside the track 11. A movable groove is provided at the bottom of the track 11. A suspension rod 12d passes through the movable groove and is connected to the bottom of the mounting frame 12a. A pulley 12b group is installed on the mounting frame 12a. A first driving motor 12c is installed on the mounting frame 12a, and its output shaft is connected to the axis of the pulley 12b to drive the pulley 12b to move along the track 11.

[0046] It should be noted that the track 11 is a square tube track 11, which is circumferentially closed and has a movable groove at the bottom of the track 11. The driving device 12 and the track 11 are driven by friction, which has the advantages of simple structure and easy installation. It can simplify the overall installation structure and is conducive to the use and promotion of the present invention.

[0047] Under the gravity load applied by the three-axis telescopic arm 2 and the capture control end 3, the pulley 12b can be tightly in contact with the track 11, and the stability and accuracy of the operation of the pulley 12b can be maintained during the operation. Since errors are inevitable during long-term operation, the present invention also adopts the following structure:

[0048] like Figures 8-9 As shown, sensors 13 are evenly spaced or randomly arranged on the top of the track 11, and the signal input end of the sensor 13 is communicatively connected with the signal output end of the controller 32 to identify the position of the driving device 12 and output the sensing signal to the controller 32. The control system 32a provided in the controller 32 includes a coordinate calibration module 32a1, which is suitable for analyzing the signal of the sensor 13 and calibrating the current position of the capture control terminal 3 according to the fixed position of the sensor 13.

[0049] The specific process of the installation mode includes:

[0050] Step 1: The user sets a number of sensors 13 that can cover the track 11 in an equal or random manner according to the length of the track 11 (the equal spacing can improve the position accuracy of the driving device 12 within the spacing, and the random setting can reduce the cost of the arrangement and improve the efficiency);

[0051] Step 2: Taking the starting point of the track 11 as the zero point, obtain the coordinates of each sensor 13;

[0052] Step 3: When the sensor 13 senses the driving device 12, the current coordinates are updated based on the coordinates of the sensor 13.

[0053] Step 31, the signal sensed by the sensor 13 is output to the controller 32;

[0054] Step 32, after the coordinate calibration module 32a1 recognizes the signal sensed by the sensor 13, it extracts the coordinates of the current sensor 13;

[0055] Step 33: Update the coordinates of the current capture control terminal 3 based on the coordinates of the current sensor 13.

[0056] The sensor 13 may be a proximity switch, a Hall sensor 13 (a magnet needs to be provided at the corresponding position on the mounting frame 12 a ), an infrared sensor 13 , etc., which is used to sense the position of the mounting frame 12 a of the driving device 12 .

[0057] In the attached Figure 8 The position of the first drive motor 12c is not shown in the figure, and it is hidden behind the pulley 12b. The output shaft of the first drive motor 12c is connected to the pulley 12b to drive the pulley 12b.

[0058] like Figures 1-2 As shown, it is a structural diagram of the unmanned test control system of this laboratory installed in the laboratory. In this embodiment, the track 11 adopts a U-shaped track 11. After setting the inspection frequency and speed, the control system 32a controls the unmanned test control system to run automatically.

[0059] The installation mode also includes positioning parameter settings, including: controlling the drive device 12 to drive the capture control terminal 3 to run from the starting point of the track 11 to the end point of the track 11. During the operation, the image collector 33b and the distance collector 33c are used to collect the height of each experimental instrument 6, the distance from the capture control terminal 3, and the tilt angle. The collected data is analyzed to obtain the alignment parameters corresponding to each instrument.

[0060] The alignment parameters include: the rotation angles of the first rotational motion, the second rotational motion, and the third rotational motion; the length of the linear motion; the coordinate position on the track 11 ; and the tilt angle of the capture control terminal 3 .

[0061] When the driving device 12 stops at a certain experimental instrument 6 to identify the content of its instrument through coordinate recognition, the position of the capture control terminal 3 is adjusted according to the alignment parameters, and the rotation and tilt parameters of the capture control terminal 3 are adjusted to make its image acquisition device 33b face the instrument of the experimental instrument 6 to avoid visual errors due to height and angle deviations, so as to ensure the accuracy of the collected data.

[0062] The alignment parameters also include calibration parameters. After the image acquisition device 33b of the capture control terminal 3 is aligned with the instrument of the experimental instrument 6, data on the instruments at several deflection angles are collected and compared with the instrument facing the experimental instrument 6, and the errors of several deflection angles are calculated. The error value and the deflection angle are used as calibration parameters, and the deflection angle is used as the preset deflection angle.

[0063] The temperature collector 33a adopts an infrared temperature sensor, the image collector 33b adopts a visible light camera, and the distance collector 33c adopts a depth camera to obtain the coordinates of different targets within the field of view, so as to facilitate the capture control end 3 to locate the instruments of the experimental instrument 6 and calculate the rotation angles of the first rotational movement, the second rotational movement, and the third rotational movement of the capture control end 3; the length of the linear movement; the coordinate position on the track 11; the inclination angle of the capture control end 3, and the inclination sensor 33d detects the inclination angle of the current capture control end 3.

[0064] After detecting that the position angle of the experimental instrument 6 has changed, the alignment parameters and the calibration parameters are regenerated.

[0065] Working mode 2 (abnormal identification and processing):

[0066] Identification based on the collected working status data of the experimental instrument 6: The controller 32 collects the working status data of the experimental instrument 6 in real time. When an alarm message appears on the instrument, the alarm processing module 32a4 identifies the alarm message and performs a preset operation.

[0067] The above operations include: soft restart, fault information elimination, button triggering, etc.

[0068] When the anomaly cannot be eliminated, the measures taken include:

[0069] 1. Send alarm information to the user terminal 7. The user can receive the alarm message through the user terminal 7 and send operation instructions to the capture control terminal 3 to perform manual operation.

[0070] 2. Control the data collector 33 to collect instrument data from the experimental instrument 6, collect, organize and save the collected data to avoid loss of subsequent test data.

[0071] Abnormal conditions in the laboratory are identified based on the captured temperature data and image data in the laboratory: the controller 32 collects and analyzes the data in the laboratory through the temperature collector 33a and the image collector 33b to identify abnormalities in the laboratory.

[0072] The above identification includes:

[0073] Temperature anomaly identification. When the control system 32a controls the capture control terminal 3 to inspect along the track 11, the temperature collector 33a captures the temperature data within the collection range in real time, and monitors the temperature of each experimental instrument 6 according to the set temperature threshold of different experimental instruments 6. When an abnormality is found, the experimental instrument 6 is processed by shutting down, starting the abnormality handling program, sending an alarm message to the user terminal 7, etc.

[0074] Other abnormality identification: According to the preset abnormal image features, the control system 32a controls the capture control terminal 3 to analyze the data obtained by the image collector 33b in real time during the inspection along the track 11, and performs corresponding processing according to the preset processing scheme and sends alarm information to the user terminal 7 for processing.

[0075] Working mode three (reflection elimination):

[0076] like Figures 3 to 6 As shown, when the control system 32a controls the capture control end 3 to collect instrument data of the experimental instrument 6, when it runs to the corresponding experimental instrument 6, the alignment module 32a3 controls the second drive motor 28 to drive the first drive joint 25 to adjust the first rotational movement angle of the second connecting segment 22, the third drive motor 29 to drive the second drive joint 26 to adjust the second rotational movement angle of the third connecting segment 23, and the fourth drive motor 30 to drive the third drive joint 27 to adjust the third rotational movement angle of the fourth connecting segment 24 according to the set alignment parameters, so that the image collector 33b is aligned with the instrument of the experimental instrument 6. In this process, when it is recognized that the image collected by the image collector 33b has reflections that affect the image collection quality, the capture control end 3 is controlled to rotate to a preset deflection angle to avoid the reflection from entering the image collector 33b. After eliminating the reflection, the image is collected, and the error caused by the deviation is calculated to calibrate the recognized data.

[0077] Working mode 4 (folding mode):

[0078] like Figure 7 As shown, in the folding mode, the capture control end 3 can be folded by the three-axis telescopic arm 2 to reduce the occupation of laboratory space and facilitate the work of the staff.

[0079] Compared with the existing method of manual attendance, after the capture control terminal 3 of the present invention is connected to the communication with the experimental instrument 6, when the abnormality of the experimental instrument 6 is identified, a recovery operation can be performed to achieve the effect of automatically recovering the function of the experimental instrument 6 to handle the abnormality. The instrument data of the experimental instrument 6 can also be directly collected to obtain and save the test data, thereby avoiding the loss of test data due to the abnormality of its control part. On the other hand, the present invention has a simple structure and is easy to install in the laboratory to replace the existing on-duty personnel, which not only saves costs but also has high reliability.

[0080] It should be noted that the specific models and specifications of the first drive motor 12c, the second drive motor 28, the third drive motor 29, the fourth drive motor 30, the controller 32, the sensor 13, the temperature collector 33a, the image collector 33b, the distance collector 33c, and the inclination sensor 33d need to be selected and determined based on the actual specifications of the device. The specific selection and calculation method adopts the existing technology in this field, so it will not be described in detail.

[0081] The power supply and principles of the first drive motor 12c, the second drive motor 28, the third drive motor 29, the fourth drive motor 30, the controller 32, the sensor 13, the temperature collector 33a, the image collector 33b, the distance collector 33c, and the tilt sensor 33d are clear to those skilled in the art and will not be described in detail herein.

[0082] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
