Description

Technical Field

[0001] This invention relates to the field of automation, and in particular to an instrument testing method and testing apparatus. Background Technology

[0002] With the continuous development of science and technology, people have manufactured increasingly sophisticated instruments and meters. Consequently, the testing requirements for these highly precise instruments and meters are also becoming increasingly stringent. Instruments and meters are tools or equipment used to detect, measure, observe, and calculate various physical quantities, material compositions, and physical properties. Vacuum leak detectors, pressure gauges, length measuring instruments, microscopes, and multipliers all fall under the category of instruments and meters. In a broader sense, instruments and meters can also have functions such as automatic control, alarm, signal transmission, and data processing. After the instruments and meters are manufactured, they need to be inspected to ensure they meet the standards for use. The testing of some instruments and meters also includes testing for airtightness and water resistance.

[0003] Currently, the electrical equipment manufactured by various manufacturers is becoming increasingly sophisticated, leading to higher and higher demands on the precision of testing instruments. Furthermore, to further ensure the accuracy of test results, relying solely on instruments is insufficient. It is necessary to utilize predetermined equipment attribute information established during the production process of electrical equipment, in conjunction with the actual equipment attribute information tested by the instruments. By combining and comparing these two information, more accurate test results can be obtained. However, this testing method requires access to the manufacturer's internal database. The data stored in the database involves highly confidential information, thus compromising security and increasing the risk of information leaks. Moreover, accessing the database requires multiple levels of approval from higher management, severely impacting work efficiency. Therefore, there is an urgent need for an instrument testing method and its testing device. Summary of the Invention

Attached Figure Description

[0028] To more clearly illustrate the technical solutions in the embodiments of the present invention or the prior art, the drawings used in the embodiments will be briefly introduced below. Obviously, the drawings described below are only some embodiments of the present invention. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort.

[0029] Figure 1 This is a flowchart of the instrument testing method of the present invention;

[0030] Figure 2 This is a schematic diagram of the unit division of the instrument and meter testing device of the present invention;

[0031] Figure 3 This is a schematic diagram of the instrument testing device of the present invention. Detailed Implementation

[0032] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. 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 making creative efforts are within the scope of protection of the present invention.

[0033] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0034] Reference Figure 1 This invention provides a method for testing instruments and meters, comprising the following steps:

[0035] Step 1: Obtain the device attribute information of the device under test through actual testing. The actual testing means that the staff uses instruments to test the device under test on site and uploads the device attribute information obtained from the test to the cloud.

[0036] Step 2: After at least two unlocking operations, the database is unlocked. This step is performed by designated personnel who download the device attribute information obtained from actual testing from the cloud and then unlock the database through multiple unlocking operations.

[0037] Step 3: Extract the equipment attribute information of the pre-determined equipment to be tested from the database. According to the classification of the equipment to be tested, specific personnel extract the corresponding pre-determined equipment attribute information from the database.

[0038] Step 4: Use wired network or wireless local transmission to export the predetermined device attribute information of the device under test. Connect the computer terminal through a wired network, or perform wireless local transmission of the predetermined device attribute information in the same local area network environment to improve transmission efficiency.

[0039] Step 5: Compare the predetermined device attribute information of the device under test with the actual device attribute information obtained during the test to obtain the test result deviation value;

[0040] Step Six: Output the test result deviation value and make an evaluation based on the test result deviation value. Based on the evaluation result, not only can more accurate test results be obtained, but the test result deviation value can also be used to determine whether there is a problem with the instrument. This allows the performance of the instrument to be tested during the test, which greatly improves work efficiency.

[0041] To further optimize the scheme, in step two, the unlocking operation includes key unlocking and facial recognition unlocking. The key is set by the superior department and an encryption algorithm is generated. Specific technicians need to enter the correct key to unlock the device. At the same time, specific technicians need to enter their facial information to unlock the device through facial recognition.

[0042] To further optimize the solution, before step four, the device attribute information of the predetermined device under test is segmented into multiple file packages, and these file packages are automatically backed up during transmission. If an anomaly occurs during transmission, the transmission is interrupted, and then the remaining file packages (excluding the backed-up ones) are transmitted. This ensures that the entire transmission process will not restart due to packet loss.

[0043] This method first utilizes instruments for actual testing to obtain the device attribute information of the device under test. Designated personnel can directly access the database through multiple unlocking operations and extract the predetermined device attribute information from the database, preventing information leakage and improving security. The extracted device attribute information is directly transmitted to a computer terminal via wired or wireless local transmission. The computer terminal then compares the predetermined device attribute information with the actual device attribute information obtained from the test to obtain the test result deviation value. An evaluation is then made based on the test result deviation value, significantly improving the efficiency of data retrieval and thus ensuring testing efficiency. Furthermore, the evaluation results not only yield more accurate test results but also allow for the determination of whether there are problems with the instruments based on the test result deviation value.

[0044] Reference Figure 2-3 This invention provides an instrument testing device integrated into an industrial control computer, comprising:

[0045] The first startup unit includes an input module, which is connected to a first judgment module and a user interface. The first judgment module is used to determine whether the input key is correct. The input module is used to input the key, and when the key is entered correctly, the user interface of the industrial control computer is started.

[0046] The second startup unit includes a classification module connected to the user interface. The classification module is connected to a second judgment module, which is used to determine whether the face recognition matches. The touch screen user interface selects the correct information data according to the classification of the device under test. The classification module starts the opening of the data of the corresponding category in the database. After the classification module starts, face recognition is required before the next instruction can be passed. The face acquisition module installed outside the industrial control computer collects face data and recognizes the face data through the face recognition module. The second judgment module determines whether the face recognition matches. If the face recognition matches, the data of the corresponding category in the database is opened.

[0047] The data management unit includes a data extraction module connected to the second judgment module. The data extraction module is connected to the database and extracts data of the corresponding category from the database.

[0048] The wired data transmission test unit includes a wired network transmission module. The input end of the wired network transmission module is connected to the database, and the output end of the wired network transmission module is connected to a comparison module. The comparison module is connected to a test result output module. If wired network transmission is selected, the computer terminal is connected to the industrial control computer via a network cable. The device attribute information of the device under test obtained by the actual test is input into the comparison module through the computer terminal. After the device attribute information of the device under test is input into the comparison module, the comparison module compares the parameters, and the test result output module outputs the test result deviation value.

[0049] The wireless data transmission test unit includes a wireless local transmission module. The input end of the wireless local transmission module is connected to the database, and the output end of the wireless local transmission module is connected to a comparison module. The comparison module is connected to a test result output module. The difference from the wired network transmission mentioned above is that the industrial control computer is connected to the computer terminal through a local area network to realize wireless local transmission.

[0050] The computer terminal is connected to the test result output module and the comparison module. The computer terminal inputs the device attribute information of the device under test obtained from the actual test to the comparison module. At the same time, the comparison module receives the predetermined device attribute information of the device under test, then compares the parameters, and the test result output module outputs the test result deviation value.

[0051] To further optimize the scheme, the first judgment module is connected to an encryption setting unit. The encryption setting unit includes an encryption algorithm generation module connected to the first judgment module. The encryption algorithm generation module is connected to a key setting module. The key setting module is used to input the set key, and the encryption algorithm generation module automatically generates an encryption algorithm based on the set key and transmits it to the industrial control computer to realize the locking function.

[0052] In a further optimized solution, the second judgment module is connected to a face recognition module, which in turn is connected to a face acquisition module. The face acquisition module is preferably a camera and is located outside the industrial control computer. The face acquisition module is used to collect face data and transmit it to the face recognition module for recognition, working in conjunction with the second judgment module to determine whether the face information matches.

[0053] The solution has been further optimized. The database connection includes a data segmentation module, which is connected to both a wireless local transmission module and a wired network transmission module. Both the wired network transmission module and the wireless local transmission module are connected to an automatic backup module. Before transmitting data, the device attribute information of the predetermined device under test is segmented into multiple file packets for transmission. During transmission, the automatic backup module automatically backs up the transmitted file packets. If an anomaly occurs during transmission, the transmission is interrupted, and then the remaining file packets (excluding the backed-up ones) continue to be transmitted. This ensures that the entire transmission process will not restart due to packet loss.

[0054] To further optimize the solution, the transmission lines between the data segmentation module and the wireless local transmission module, as well as the transmission lines between the data segmentation module and the wired network transmission module, are all connected to a transmission path detection module. The transmission path detection module is connected to an alarm module, which is connected to the user interface. When the transmission path detection module detects an error in the transmission path, the alarm module transmits the alarm information to the user interface and interrupts the transmission to prevent erroneous data from affecting the test results.
