Description

Technical Field

[0001] This utility model relates to the field of tobacco testing technology, specifically to a remote metering device for a comprehensive testing platform for the physical properties of cigarettes and filter rods. Background Technology

[0002] The comprehensive testing platform for the physical properties of cigarettes and filter rods is an important piece of equipment for the quality control of cigarettes and filter rods.

[0003] Currently, the metrology work for key physical performance testing equipment in cigarettes mainly adopts a traditional working mode, where professional technicians from higher-level metrology institutions bring standard instruments to tobacco companies for on-site measurement. This results in a significant waste of manpower, resources, and time, and the efficiency of metrological calibration is low. Furthermore, this traditional metrology model, which relies too heavily on manual labor, cannot meet the needs of the tobacco industry's digital transformation and intelligent manufacturing development. Therefore, research into remote metrology technology has been put on the agenda.

[0004] Current research on remote metrology technology mainly focuses on remote calibration technology. Based on the concept of remote calibration, the realization of remote calibration can be divided into two methods: the metrological standard is on-site and the metrological standard is not on-site.

[0005] The remote calibration method for metrological standards in the field refers to the higher-level metrology center collecting the status information of the instrument being calibrated during the calibration process through data acquisition and communication technology, and finally obtaining the calibration result after data processing.

[0006] However, in practice, there are many parameters that need to be measured and many devices that need to be connected, which presents many obstacles in actual application.

[0007] The on-site data collection includes two basic requirements: one is to collect data from some metering and calibration equipment installed locally, and the other is to obtain data through secondary calibration using a standard brought to the site. Therefore, it is necessary to design a device that can integrate the above requirements and has portability to optimize the remote metering scheme.

[0008] In order to solve the above problems, people have been seeking an ideal technological solution. Utility Model Content

The end of the thermo-humidity and barometer is used to be inserted into the slot of the thermo-humidity and barometer extension rod to obtain environmental parameters.

[0020] The environmental data interface is located in the extension rod of the temperature, humidity and barometer, or in the second storage compartment, or in another location on the outer casing.

[0021] Based on the above, the various standards also include standard parts or standard part kits that are set independently of the housing space, including any one or two or more combinations of suction resistance, ventilation rate, length, mass, circumference and hardness.

[0049] In this embodiment, the thermo-hygrometer and barometer are integrated into a single cylindrical thermo-hygrometer and barometer. The second storage compartment 6 includes a circular channel extending into the interior of the outer shell. The thermo-hygrometer and barometer are temporarily stored in the circular channel. An atmospheric pressure port 16 is provided on the rear side of the outer shell as a pressure connection port for the thermo-hygrometer and barometer.

[0050] In this embodiment, to avoid interference from the space constrained by the outer shell on temperature, humidity and atmospheric pressure, a groove is provided on the top of the outer shell and a temperature, humidity and barometer extension rod 1 is hinged in the groove. A slot is provided at the end of the temperature, humidity and barometer extension rod 1.

[0061] Through these rich data interfaces, the measuring device can connect to various standards to acquire data collected by the standards, and connect to the measuring equipment under test to acquire data from the measured equipment in real time, as well as data from some measuring standards placed locally. At the same time, it can also establish service connections with remote laboratories, control centers or the cloud to transmit measuring data through the network.

[0062] The device is also equipped with auxiliary equipment, including a camera, headset, power supply and device connection cable, which are connected to the housing via a quick-connect device connection cable.

[0063] Before operating the device for a measurement task, preparations need to be made, including: taking out the various connecting cables, connecting the power supply to the interface to be connected, for example, connecting the network interface 11 or network interface 12 to the device to be measured through a network cable, and connecting the suction resistance atmospheric pressure port 19 and the suction resistance measurement port 20 to the suction resistance measurement unit on the device to be measured through a sealed flexible tube, etc.

Operate the display screen 2 and enter the username and password to log in to the system. The microcontroller 27 is equipped with the Microsoft Windows system and has the necessary software installed.

[0065] In this embodiment, the specific implementation of the device is illustrated using a length measurement module as an example.

[0066] Measurement process:

[0067] Step 1) Operate the device to be measured into calibration mode and select length measurement.

[0068] Step 2) Select the length calibration mode on display screen 2.

[0069] Step 3) Take out the length standard bar from the set of standard parts carried, select the standard bar to be measured (taking a 70 mm length standard bar as an example), align the barcode affixed to it with the barcode scanner 3, the barcode scanner 3 recognizes the length of the selected standard bar, and the display screen 2 displays its length and the words "listening", indicating that calibration can begin.

[0070] Step 4) Place the selected length standard bar into the length measurement module of the device to be measured, and operate the device to perform the measurement. This usually requires repeating the measurement 10 times. The data acquisition and network communication module collects the 10 length measurements taken by the device and displays them on display screen 2. Once all measurements are completed and the data display is complete without omissions or obvious errors, click the "Save Data" button on display screen 2 to save all measurement results of the selected length standard bar to an Excel file in the background.

[0071] Step 5) Collect the measured length standard bar, select another length standard bar, and repeat steps 3) and 4) until all the required length standard bar data are obtained.

[0072] The measurement task of the length measurement module has ended.

[0073] The calibration and measurement work of other measurement modules in other embodiments is roughly the same as that of the length measurement module.

[0074] It should be noted that the software used in the above process is existing calibration software in the industry, and it performs all the functions that existing software can perform. When applying this solution, the main task is to integrate the above functions into a single device for use.

[0075] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and not to limit it; although the utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications can still be made to the specific implementation of this utility model or equivalent substitutions can be made to some technical features without departing from the spirit of the technical solution of this utility model, and all such modifications and substitutions should be covered within the scope of the technical solution claimed by this utility model.
