Description

Technical Field

[0001] The present invention relates to the field of instrument detection technology, and in particular to a detection system and a detection method based on industrial Internet identification interpretation. Background Art

[0002] Currently, instrument manufacturers must conduct factory inspections on all instruments before they leave the factory. They must then send all instruments to a calibration agency for further inspection. Only after passing the inspections and issuing a certificate of conformity can the instruments be released to end users. This process requires repeated inspections of the instruments, requiring duplication of procedures and consuming considerable time and costs. Summary of the Invention

[0003] In view of the shortcomings of the existing technology, the present invention aims to provide a detection system and method based on industrial Internet identification interpretation.

[0004] In order to achieve the above object, the present invention adopts the following technical solutions:

[0005] A detection method based on industrial Internet identification interpretation, the specific process is as follows:

[0006] S1. Preparation before testing: The instrument manufacturer applies for testing services from the verification agency. After reviewing the instrument manufacturer's information, the verification agency issues a monitoring controller and an identity resolution enterprise node to the instrument manufacturer, and opens an account for remote reception of test data for the instrument manufacturer. The instrument manufacturer applies to the identity resolution service platform for registration of an industrial Internet identity resolution enterprise account through the identity resolution enterprise node, and then applies to the identity resolution service platform for an industrial Internet device identity for the testing device through the identity resolution enterprise node, and stores the applied industrial Internet device identity in the monitoring controller.

[0007] S2. The monitoring controller sends the pre-stored industrial Internet device identifier of the detection device to the identity resolution enterprise node to apply for identity resolution. The identity resolution enterprise node returns attribute information corresponding to the detection device based on the industrial Internet device identifier.

[0008] S3. The main control computer sends a command to notify the monitoring controller to start a verification process. After receiving the command from the main control computer, the monitoring controller enters the monitoring working mode, that is, it copies the data of each port connected to the detection device and sends it to the remote verification management platform in real time;

The returned data includes at least the meter ID, the current accumulated flow value, and the timestamp of the data received.

[0025] S4.5. The main control computer determines whether the accuracy and refresh rate of the data sent back by the instrument under test meet the test requirements. If not, the computer returns to step S4.2 and repeats until the requirements are met.

[0026] S4.6. The main control computer notifies the flow computer to obtain the data of the standard table in real time;

[0049] The beneficial effects of the present invention are:

[0050] 1. This invention uses identity resolution technology and processes to ensure that the instrument manufacturer's testing environment cannot be arbitrarily modified. If the company's testing device has not registered its Industrial Internet device identifier, or has registered its identifier but modified its configuration information without synchronizing it to the identity resolution enterprise node, the monitoring controller will not be able to identify the testing device, resulting in the device's test data being unable to be transmitted back to the calibration organization's remote calibration management platform.

[0051] 2. The present invention ensures that the original factory inspection process and method of the instrument manufacturer are not changed by setting the monitoring controller hardware, and obtains all the original records of the instrument manufacturer's inspection process.

[0052] 3. In the present invention, during a complete detection process, the monitoring controller must first parse the platform identifier of the remote verification management platform before sending data once, thereby realizing reliable data collection for third-party circumstantial evidence.

[0053] The present invention can combine the two existing detection processes into one, effectively reducing the enterprise's detection costs while ensuring the detection quality. BRIEF DESCRIPTION OF THE DRAWINGS

[0059] The present invention will be further described below in conjunction with the accompanying drawings. It should be noted that this embodiment is based on the technical solution and provides a detailed implementation method and specific operation process, but the protection scope of the present invention is not limited to this embodiment.

[0060] Example 1

[0061] This embodiment provides a detection method based on industrial Internet identification interpretation, such as Figure 2-5 As shown, the specific process is:

[0062] S1. Preparation before testing: The instrument manufacturer applies for testing services from the calibration agency. After reviewing the instrument manufacturer's information, the calibration agency issues a monitoring controller and an identity resolution enterprise node to the instrument manufacturer, and opens a remote detection data receiving account for the instrument manufacturer. The remote detection data receiving account is used to identify the detection data initiated by each instrument manufacturer. The instrument manufacturer applies to the identity resolution service platform to register an industrial Internet identity resolution enterprise account through the identity resolution enterprise node. Then, through the identity resolution enterprise node, the instrument manufacturer applies to the identity resolution service platform for an industrial Internet device identity for its own detection device, and stores the applied industrial Internet device identity in the monitoring controller. In this embodiment, the detection device includes a flow computer, a detected instrument, a PLC, and a flow sensor on the detection pipeline.

[0063] Connect the instrument to be tested, the standard meter, and the flow sensor to the test pipeline, connect the valve that controls the on / off of the test pipeline to the PLC, connect the instrument to be tested and the standard meter to the flow computer, connect the PLC, the flow computer, and the flow sensor to the monitoring controller, connect the monitoring controller to the main control computer, and connect the main control computer to the local detection management system;

[0064] S2.

[0065] S3. The main control computer sends an instruction to notify the monitoring controller to prepare to start a calibration process. After receiving the instruction from the main control computer, the monitoring controller enters the monitoring working mode, that is, it copies the data of each port connected to the detection device and sends it to the remote calibration management platform in real time. Initially, the monitoring controller works in the transparent transmission mode and does not copy the communication data of each port. Specifically, the monitoring controller sends the data to the remote calibration management platform in real time through the remote calibration service gateway. It should be noted that during a complete detection process, the monitoring controller needs to apply to the identity resolution enterprise node to resolve the platform identification of the remote calibration management platform before sending data each time, obtain the communication address of the remote calibration management platform, and then send the data. That is, the platform identification of the remote calibration management platform must be resolved once before sending data.

Based on the test configuration information, the flow computer notifies each instrument under test to enter test mode. The instrument under test returns feedback to the flow computer, which then returns this information to the master computer, notifying the master computer that the command to enter test mode has been executed. It should be noted that the flow computer does not determine whether the instrument under test has correctly entered test mode; it only provides feedback to the master computer based on the feedback from the instrument under test.
