Description
Technical Field
[0001] The present invention belongs to the technical field of calibration of gas detection equipment, and provides a calibration device for a zero gas generator that does not require manual replacement of gas cylinders for detection, and can control the calibration of the gas path only through the software side. In particular, it relates to an intelligent mobile zero gas generator calibration device and a usage method. Background Art
[0002] With the release of the national standard calibration specification for zero gas generators, calibration work for zero gas generators has been successively carried out in many regions across the country. For example, relevant calibration work has been carried out in Xinjiang, Gansu, Jiangsu, Guangdong, Shanghai, Guizhou and other places, comprehensively detecting the zero gas generators of local motor vehicle inspection institutions, standardizing the use of local zero gas generators, and ensuring the accurate and reliable gas components produced by zero gas generators. However, some usage problems have also been found during the detection process. The zero gas generators on the market are mainly detected by Fourier transform infrared analyzers. After the standard gas passes through the zero gas generator, the zero gas generator is then connected to the Fourier analyzer. Since six gases need to be detected in the standard, and the Fourier transform infrared analyzer requires high-purity nitrogen as the background gas, it is necessary to frequently replace gas cylinders in the detection process. The entire detection process is relatively troublesome, and a certain amount of standard gas is wasted when replacing the standard gas.
[0003] Before detection, the Fourier transform infrared analyzers on the market need to be preheated and purged with high-purity nitrogen to obtain the background spectrum diagram. Only after the background spectrum diagram is completed can the detection be carried out. Then, the zero gas generator needs to connect oil-free compressed air or introduce gas with the standard required concentration at the inlet, and the outlet of the zero gas generator is connected to the Fourier transform infrared analyzer for detection. According to the requirements of the zero gas generator calibration specification, the standard gas needs to be a certified reference material and each gas has specific requirements, which makes it impossible to use a single mixed gas for the detection of all gases. According to the existing national certified reference materials, at least five bottles of reference materials are required to meet the detection needs. Therefore, a large amount of time is required to replace gas cylinders for the detection of all gases. There is also a situation of gas waste when replacing gas cylinders. At the same time, the work of replacing gas cylinders is relatively unfriendly to female detection personnel.
[0004] Therefore, a research on a movable intelligent control device is carried out to more accurately control the air pressure and flow rate of all gas paths during the detection process of the zero gas generator, change the existing control method through ordinary pressure regulating valves and rotameters, improve the intelligent level of control, and reduce the frequency of standard gas replacement. This intelligent control device can optimize the detection process, reduce the operation complexity caused by frequently replacing different standard gases, make the detection process more efficient and convenient, reduce the waste of standard gas, reduce unnecessary gas loss through intelligent control, save the detection cost, and improve the resource utilization rate.

All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the scope of the present invention.
[0023] Embodiment 1 As Figures 1 to 3As shown in the figure, this embodiment proposes an intelligent mobile zero-gas generator calibration device, which includes a standard gas fixing device 2, a gas distribution control device 5, a mobile device 3, a software control system 1, and a Fourier transform infrared analyzer 4. The standard gas fixing device 2 adopts an adjustable fixing frame for fixing standard gas cylinders of different specifications.

[0027] The software control system 1 includes an operation interface and a control program. The operation interface is provided with a detection item selection area. By clicking on different items in the detection item selection area, the control program is triggered to issue instructions to control the gas path switching of the gas distribution control device 5 to realize the detection of different standard gases.
[0028] The operation interface is also provided with a real-time data display area for displaying various parameters during the calibration process of the zero gas generator in real time. The parameters include gas pressure, flow rate, and gas composition data detected by the Fourier transform infrared analyzer 4.
[0029] The housing of the mobile device 3 is made of high-strength and shock-absorbing materials, and a buffer structure is provided inside. The anti-vibration test chamber is installed on the buffer structure to reduce the influence of external vibration on the Fourier transform infrared analyzer 4.
[0030] The gas distribution control device 5 is also provided with a gas purification unit. The gas purification unit is arranged in the gas passage for purifying the gas entering the gas distribution control device 5 to remove impurities and moisture in the gas.
[0031] The present invention also provides a usage method of the intelligent mobile zero gas generator calibration device, including the following steps: S1. Fix the standard gas cylinders of different specifications on the adjustable fixing frame of the standard gas fixing device 2; S2. Connect the standard gas cylinder, the interferometer air inlet and the sample chamber air inlet of the Fourier transform infrared analyzer 4, the air inlet and the air outlet 6 of the zero gas generator, and the air outlet 6 of the oil-free air compressor to the corresponding interfaces of the gas distribution control device 5 respectively through the quick-connect gas pipes; S3. Turn on the software control system 1 and select the items to be detected on the operation interface; S4. The software control system 1 issues instructions according to the selected detection items. The gas distribution control device 5 switches the gas path according to the instructions and controls the gas pressure and flow rate to make the corresponding standard gas enter the Fourier transform infrared analyzer 4 and the zero gas generator for detection; S5. During the detection process, view the detection parameters in real time through the operation interface of the software control system 1; S6. After the detection is completed, turn off the software control system 1 and disconnect the connection between each device and the gas distribution control device 5.
[0032] The specific steps are as follows: (1) Device installation and connection Place the mobile device 3 in a stable working area, ensure that the rollers are locked, open the adjustable fixing frame of the standard gas fixing device 2, and manually or through software control adjust the relative position of the fixing parts according to the specifications of the standard gas cylinder to firmly fix the standard gas cylinder; Use quick-connect air pipes to connect the gas outlet 6 of the calibration gas cylinder to the corresponding calibration gas interface on the gas distribution control device 5 in sequence. Connect the interferometer gas inlet and the sample chamber gas inlet of the Fourier transform infrared analyzer 4 to the corresponding interfaces of the gas distribution control device 5. Connect the gas inlet and the gas outlet 6 of the zero gas generator to the corresponding interfaces of the gas distribution control device 5 respectively. Finally, connect the gas outlet 6 of the oil-free air compressor to the designated interface of the gas distribution control device 5. After the connection is completed, check whether the connections of all interfaces are tight to prevent gas leakage.
[0033] (II) Software system settings Turn on the software control system 1, and the system automatically performs initialization detection, including the detection of equipment such as each gas path channel, sensor, and electromagnetic reversing valve of the gas distribution control device 5, to ensure that the device is in a normal working state. If an abnormality is detected, the system will display a fault message on the operation interface and prompt for repair. In the parameter setting module of the software operation interface, set relevant detection parameters according to the model of the zero gas generator to be detected, detection standard requirements, etc., such as gas flow range, pressure range, detection item sequence, etc. At the same time, you can choose whether to turn on the function of automatically associating auxiliary detection items according to actual needs.
[0034] (III) Operation during the detection process In the detection item selection area of the software operation interface, click on the item to be detected. The software control system 1 controls the gas path switching module of the gas distribution control device 5 according to the preset algorithm and instructions, opens the corresponding gas channel, and enables the required standard gas to enter the Fourier transform infrared analyzer 4 and the zero gas generator according to the set pressure and flow rate. During the detection process, the software control system 1 real-time collects the gas component data detected by the Fourier transform infrared analyzer 4, and the pressure and flow rate data feedback by the pressure sensor and the flow sensor, and displays them in the real-time data display area of the operation interface. The system uses a dynamic optimization algorithm based on these real-time data to automatically adjust the pressure and flow rate of the gas in the gas distribution control device 5 to ensure the stability and accuracy of the detection process. If abnormal data fluctuations occur during the detection process, the software control system 1 immediately starts the abnormal diagnosis mechanism. The system analyzes the cause of the abnormality according to the preset diagnosis model, such as gas path blockage may be due to impurity accumulation, electromagnetic reversing valve failure may be due to electrical faults, etc. According to the diagnosis result, the system automatically takes corresponding adjustment strategies, such as increasing the gas flow rate to flush the gas path, switching to the standby electromagnetic reversing valve, etc., and displays the abnormal information and the processing result on the operation interface.
[0035] (IV) Processing of detection results After the detection is completed, the software control system 1 analyzes and processes all the collected detection data. Using data analysis models and algorithms, it calculates key indicators such as the content and purity of each component in the gas generated by the zero gas generator, and compares them with the standard values to determine whether the zero gas generator meets the calibration specification requirements; The software control system 1 displays the detection results in an intuitive visual chart (such as a bar chart, line chart, etc.) and a detailed report on the operation interface. The report content includes the detection items, detection results, comparative analysis with the standard values, performance evaluation of the zero gas generator, and improvement suggestions, etc. Users can export the detection results as an electronic document or print a paper report according to their needs; The software control system 1 automatically archives and stores all the data of this detection, establishing a detection database. The data archiving includes information such as detection items, detection parameters, detection results, analysis reports, and detection time, which is convenient for users to query and trace in the future.
[0036] In this embodiment, the software control system 1 of this device consists of an operation interface, a control program, a data storage and analysis module, and a communication module. The operation interface provides an interaction platform for users, where users can select detection items and other operations. The control program, according to the user's instructions and preset algorithms, sends specific control signals to the gas distribution control device 5. The data storage and analysis module is used to record and process various types of data during the detection process, and the communication module is responsible for data transmission between the software control system 1 and the gas distribution control device 5.
[0037] This intelligent mobile zero gas generator calibration device controls the gas path switching with one key on the software. Specifically: After the user turns on the software control system 1 and enters the operation interface, there is a detection item selection area on the operation interface. The user only needs to click on the item to be detected, and this operation will immediately trigger the control program in the software control system 1; After receiving the detection item information selected by the user, the control program quickly generates corresponding gas path switching instructions according to the pre-set rules and algorithms. These instructions include information on the gas path channels to be opened or closed, parameters such as the target air pressure and flow rate of the gas. At the same time, the control program will parse these instructions in detail to ensure the accuracy and integrity of the instructions; The communication module sends the parsed gas path switching instructions to the control module of the gas distribution control device 5. To ensure the reliability and stability of data transmission, the communication module uses an efficient and stable communication protocol, such as the Modbus protocol, etc. During the transmission process, the data will be encrypted and verified to prevent data loss or errors; After the control module of the gas distribution control device 5 receives the gas path switching instruction, it first verifies the instruction. If the instruction verification passes, the control module will control the actions of each electromagnetic directional valve in the gas path switching module according to the instruction content. For example, if a certain specific standard gas is required for the detection item, the control module will open the electromagnetic directional valve on the corresponding gas path and close the electromagnetic directional valves on other unnecessary gas paths at the same time, so as to achieve a rapid switching of the gas path; After the gas path switching is completed, the control module will accurately control the gas pressure and flow according to the target pressure and flow parameters in the instruction. The pressure sensor and the flow sensor will detect the gas pressure and flow in the gas path in real time and feed the detection signals back to the control module. The control module will dynamically adjust the gas pressure and flow by adjusting devices such as gas regulating valves according to the difference between the feedback signal and the target parameter, so as to ensure that the gas enters the detection device with a stable and accurate gas pressure and flow; The control module of the gas distribution control device 5 will feed back the status information of the gas path switching (such as whether the gas path switching is successful, the opening and closing status of each current gas path, etc.) and the real-time gas pressure and flow data to the software control system 1. The software control system 1 receives these feedback information through the communication module and displays it in the real-time data display area of the operation interface, so that the user can understand the execution situation of the gas path switching and the gas parameter status in real time; If an abnormal situation occurs during the gas path switching process, such as a failure of the electromagnetic directional valve, the gas pressure or flow exceeding the safe range, etc., the control module of the gas distribution control device 5 will immediately detect the abnormality and feed back the abnormal information to the software control system 1. After receiving the abnormal information, the software control system 1 will start the abnormal handling mechanism, display detailed abnormal information and solution prompts on the operation interface, and at the same time automatically take corresponding protection measures, such as closing all gas path channels, stopping gas supply, etc., to ensure the safety of the equipment and personnel; Suppose the user selects a detection item for a certain specific gas component of the zero gas generator on the operation interface. After receiving this selection, the software control system 1 quickly generates a gas path switching instruction. The instruction requires opening the gas path channel storing the specific standard gas and adjusting the gas flow to an appropriate detection value. The communication module sends the instruction to the gas distribution control device 5. After receiving the instruction, the control module opens the corresponding electromagnetic directional valve to allow the specific standard gas to enter the gas path. The pressure sensor and the flow sensor monitor the gas pressure and flow in real time. The control module continuously adjusts the regulating valve according to the feedback data to make the gas flow stable at the preset value. During the whole process, the software operation interface displays the gas path switching status and gas parameters in real time. If an abnormality occurs, the system will issue an alarm in time and give handling suggestions.
