[0043] Figure 1The flowchart of a comprehensive calibration method based on the Internet according to a preferred embodiment of the present invention is shown in FIG. In order to solve the problems of low efficiency, high labor cost and complicated calibration procedures of traditional calibration, the embodiment of the present application provides a comprehensive calibration method based on the Internet, the method comprising:

[0044] Preferably, in step 101: establish an association between the calibration certificate number and identification information of the test product to be tested, including: recording the test product to be tested, setting identification information for the test product to be tested, and generating a calibration certificate number for the test product to be tested; the calibration certificate number and the identification information are one-to-one corresponding. The calibration platform of the present application assigns accounts to users, and users log in to the system according to the assigned accounts. When the tester opens the calibration software and enters the account login page, the calibration software and server will verify and record the login information, and make preliminary preparations for the subsequent granting of calibration authority. The activity diagram of the account login is shown in the figure below. Figure 6 As shown. The application manager or front desk staff completes the registration of the test products to be tested through the test management system and assigns them to the test personnel account. The test management system automatically assigns a unique certificate number to each test product. The tester selects the appropriate test standard device through the calibration software according to the assigned certificate number. The server connects to the network adapter interface of the standard device under the action of the calibration software according to the selected test calibration device. The network adapter interface converts the protocol and interface, connects the calibration software and the metering module to complete the test task, and feeds the test results back to the calibration terminal. The experimenter queries through the calibration software. The functional schematic diagram is shown as follows Figure 7 shown.

[0045] Preferably, in step 102: the state of a metrology standard module matching the sample to be tested is obtained; and when the state of the metrology standard module is a state allowing calibration, an instance table is generated.

[0046] Preferably, in step 103: through the calibration certificate number, in the established association relationship between the calibration certificate number and the identification information of the test product to be tested, the calibration process of the test product to be tested is queried; when the calibration process of the test product to be tested is queried, the test data of the test product to be tested is sent through the instance table; the test parameters received by the measurement standard module are used to calibrate the test product to be tested.

[0047] Preferably, in step 104: the calibration data of the test product to be tested is obtained, and the calibration data is standardized to generate a calibration certificate for the test product to be tested.

[0048] Preferably, the method comprises: the instance table records the identification of the metrology standard module matching the sample to be tested and the identification of the network adapter corresponding to the metrology standard module.

[0049] Preferably, the method further includes managing the calibration certificate: storing the calibration certificate; and querying the calibration certificate by the calibration certificate number.

[0050] Preferably, the method further comprises: collecting information of the sample to be tested, and recording the information of the sample to be tested.

[0051] After the front desk of this application collects the test product information and enters it into the server, the server will automatically generate a certificate number for this test product calibration task. And add it to the real-time calibration task file of the calibration platform. The file is written in XML to save the list of certificate numbers to be calibrated and calibrated. The tester logs in to the server with the username and password. After a successful login, the tester can query the calibration tasks to be completed in real time on the calibration terminal software. After the tester enters the certificate number, the server will first determine whether this calibration task can be achieved. It is mainly divided into two parts. The specific flow chart is as follows Figure 8 .

[0052] The calibration process is divided into two parts: the first is the calibration task request stage, which is mainly implemented by the server. The server first retrieves the database according to the task number and queries the detailed description of the numbered task, that is, the sample calibration process file; if the corresponding sample calibration process file is not found, it means that the calibration platform cannot implement the calibration task. At the same time, the server queries to determine the metrology standard module used in this calibration, connects to the network adapter interface where the metrology module is located, and the network adapter interface cooperates with the calibration software to call the required metrology standard module. After receiving the instruction, the metrology standard module sends the current status to the server: busy, idle, faulty. After receiving the device status, the server generates an instance table, which mainly records the network adapter interface IP and metrology standard module ID required for the metrology calibration task, which is used to send data. The server ensures that the data calibration task can be completed according to the sample calibration process and the instance table. The lack of any file will return the calibration request failure to the calibration terminal software.

[0053] The second part of the calibration process is the remote calibration process. When the calibration terminal software receives the calibration request successfully and the detection instrument is successfully connected, the remote calibration program starts to run. During this process, if the on-site equipment / network failure or some other problems are found, the calibration program can be intervened or terminated in time. Remote calibration mainly uses socket network communication technology to realize the remote input and adjustment of the measurement module parameters. After the calibration is completed, the obtained data will be automatically processed and converted into standard calibration data, and the calibration certificate will be automatically generated and the uncertainty will be assessed. Finally, the obtained certificate will be uploaded to the server to realize the sharing of calibration data.

[0054] The calibration method of the present application is based on Figure 2 The new comprehensive calibration platform shown in the figure is a new comprehensive calibration platform with intelligence and openness through computers, networks, network adapter interfaces, and various calibration instruments. The logical architecture of the calibration platform is as follows: Figure 3As shown. According to the characteristics of the calibration task, it is divided into four layers, namely the instrument layer, calibration layer, network layer and system / resource management layer. This application provides services to the upper layer from bottom to top, and at the same time makes service requests to the lower layer. The calibration platform of this application is a calibration system with open, shared, computing and control functions. From a functional point of view, the software functional architecture needs to have functions such as remote communication, automatic data processing, and host computer control. From the perspective of geographical location, it can be divided into calibration layer software functions, resource manager software functions and instrument layer software functions. The basis of the calibration platform function is that the three software realize data interaction through the Internet, ensure mutual control between software, and complement each other with software functions to complete the calibration business of the entire calibration platform.

[0055] The business process diagram of this application calibration platform is as follows Figure 5 As shown in the figure, account management includes login account and modification account, and its main purpose is to connect to the server to obtain calibration authority. Sample management includes sample information collection and sample information entry. The purpose of calibration management is to realize automatic calibration of samples to be calibrated. Automatic calibration includes adaptive mobilization of general measurement modules and special modules, automatic data analysis and storage, and certificate generation. At the same time, the certificate management of the calibration platform also ensures that the calibration personnel can query and download the certificate.

[0056] The entire system of the present application is built on the basis of the Internet, wherein the purpose of the network layer is to realize transparent data transmission between two end systems, and the specific functions include addressing and routing selection, establishment, maintenance and termination of network connections between devices, etc. The instrument layer and the network layer, the calibration layer and the network layer of the comprehensive calibration platform respectively run different protocols. The network layer provides a standard API interface to achieve seamless docking with the calibration layer and the instrument layer. The calibration layer mainly includes application software and some instrument interfaces. The calibration software is programmed on the basis of the network layer. Through the human-computer interaction of these calibration software, the functions of basic instrument control, calibration data transmission, calibration result query, and expert remote assistance calibration can be realized by the tester. The main tasks of the calibration layer also include the login of the tester / administrator, task creation calibration message, query calibration process, establishment of calibration task discussion group, etc. Some instrument interfaces in the calibration layer provide communication services for data transmission and instrument configuration. The system operation is inseparable from the support of hardware. At present, in the comprehensive calibration platform, the calibration field equipment will serve as the system instrument layer, and the instrument layer accepts calibration instructions, performs specific calibration operations and accepts message transmission between instruments. In the system / resource management layer, the system updates and stores the calibration database, calibration standard process, monitoring of the entire calibration system, database, application middleware and WEB service system; resource registration and software upgrade distribution of hardware and software systems; job sorting and application job scheduling, etc. Carefully analyze and identify the various causes of / causing an event, which may come from the network, the server system, the database or the application logic. Identify the root cause of the problem and take appropriate measures, such as alarming or starting an engine program. Set one-key reset and end in the system / resource management layer. Reset the entire system and terminate the task process. The physical architecture diagram of the calibration platform is as follows: Figure 4 .

[0057] The data processing module consists of a network interface, a data processing unit, a certificate generation unit, a certificate management unit, a data processing template library, and a certificate template library. The test management system sends the test data to the data processing unit through the network. The data processing unit calls the relevant test data processing template from the data processing template library according to the test type, completes the calculation and processing of the test data, and sends the processing results to the certificate generation unit. The certificate generation unit puts the processed test data into the corresponding calibration certificate template, generates a calibration certificate, and sends it back to the system / resource server for backup.

[0058] The present application realizes the automatic control of the high-power DC standard resistor box without changing the electrical structure and measurement performance of the high-power DC standard resistor box, and solves the technical problem that the high-power DC standard resistor box is difficult to use for automatic calibration tests. The automatic control method provided by the present application has the advantages of safety, high efficiency and stable performance.
