[0001] This invention relates to the field of online diagnostics, and in particular to an online diagnostic method, apparatus, device, and storage medium for a particle counter. Background Technology

[0002] Particle counters are used to monitor the size and quantity distribution of particles in environmental fluids. The particle counting sensor, as the core sensor of the particle counter, relies on the control of optical noise and the control of the light source used to identify particles to achieve the resolution of particle identification. At the same time, in order to obtain the particle distribution, the flow rate of the fluid entering the particle counting sensor needs to be controlled. In other words, the particle counter's ability to effectively obtain the size distribution and quantity statistics of particles in the monitored fluid depends on the operating parameters provided by these devices that ensure the normal operation of the particle counter. Therefore, effective monitoring of operating parameters can be used to diagnose whether there are any faults in the operation of the particle counter, and the accumulation and analysis of various control factors of the operating parameters can provide a basis for troubleshooting and product development.

[0047] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0048] Please refer to Figure 1 , Figure 1 A flowchart illustrating online diagnostics for a particle counter is provided as an embodiment of the present invention. The method may include:

[0049] S101: Obtain the device information and current operating parameter information of the particle counter to be diagnosed.

[0050] The execution subject in this embodiment is a terminal. This embodiment does not limit the type of terminal, as long as it can perform online particle counter diagnostics. For example, it can be a dedicated terminal; or it can be a general-purpose terminal. This embodiment does not limit the number of particle counters to be diagnosed. For example, there can be one particle counter to be diagnosed, or there can be multiple particle counters to be diagnosed. When there are multiple particle counters to be diagnosed, this embodiment does not limit the model of the particle counters to be diagnosed. For example, when there are multiple particle counters to be diagnosed, the model of the particle counters to be diagnosed can be the same; or when there are multiple particle counters to be diagnosed, the model of the particle counters to be diagnosed can be different. There are many types of particle counters based on their principles, such as particle counters tested by light scattering methods, etc. This embodiment does not limit the specific type of particle counter to be diagnosed.

[0051] This embodiment does not limit the content of the current operating parameter information obtained. It can be any operating parameter that affects the resolution / accuracy of the particle counter counting results. For example, it can be the flow rate information of the fluid to be measured in the particle counter; or it can be the stray light information in the particle counter that affects the accurate acquisition of particle scattered light information; or it can be the operating current information of the light source; or it can be any combination of the above information.

[0052] Furthermore, in order to efficiently and accurately evaluate and diagnose the operating status of the particle counter, the acquisition of the current operating parameter information of the particle counter to be diagnosed may include:

[0053] Obtain the current flow rate, stray light information, and light source operating current information of the particle counter to be diagnosed.

[0054] In this embodiment, stray light information can be photocurrent or voltage signal converted from stray light, flow information can be flow detection from the flu sensor, and light source operating current information can be the operating current of the light source circuit board. That is, the identification number of the device controlling the current operating parameter information can be the model of the device controlling stray light information, the model of the flow sensor controlling the flow information, and the model of the light source circuit board controlling the light source operating current information. For example, the model of the device controlling stray light information can be the internal model number of the overall structure formed by the scattering shell structure of the particle counter and the beam shaping component used by the particle counter.

[0055] S102: Determine the preset standard information corresponding to the current operating parameter information of the particle counter to be diagnosed based on the equipment information.

[0056] Furthermore, in order to accurately diagnose the particle counter to be diagnosed, the aforementioned determination of the preset standard information corresponding to the current operating parameter information of the particle counter to be diagnosed based on the equipment information may include the following steps:

[0057] The preset standard information corresponding to the particle counter to be diagnosed is determined based on the identification number of the particle counter to be diagnosed and / or the identification number of the device controlling the current operating parameter information.

[0058] This embodiment does not limit the identification number; any number that serves an identification function is acceptable, such as a model number. In this embodiment, the identification number of the device controlling the current operating parameters is determined based on the current operating parameter information. The preset standard information corresponding to the particle counter to be diagnosed is determined based on the identification number of the particle counter to be diagnosed and / or the identification number of the device controlling the current operating parameters.

[0059] S103: Compare the current operating parameter information with the preset standard information to determine whether the particle counter to be diagnosed is operating in compliance with regulations.

[0060] Furthermore, in order to accurately diagnose the operating status of the particle counter, the above-mentioned comparison of the current operating parameter information with the preset standard information corresponding to the current operating parameter information to determine whether the particle counter to be diagnosed is operating qualifiedly may include the following steps:

[0061] Step 21: Calculate the first deviation value between the current flow information of the particle counter to be diagnosed and the preset flow standard information;

[0062] Step 22: Calculate the second deviation value between the current stray light information of the particle counter to be diagnosed and the preset stray light standard information;

[0063] Step 23: Calculate the third deviation value between the current operating current information of the light source of the particle counter to be diagnosed and the preset standard operating current information of the light source;

[0064] Step 24: When the first deviation value exceeds the first threshold, or when the second deviation value exceeds the second threshold, or when the third deviation value exceeds the third threshold, the particle counter to be diagnosed is determined to be unqualified.

[0065] This embodiment does not limit the order of steps 21, 22, and 23, nor does it limit the first, second, and third thresholds. The first, second, and third thresholds can be a single value or a range of values; the user can design according to the actual situation. In this embodiment, when any one of the flow rate information, stray light information, and light source operating current information is abnormal, the corresponding abnormal information is considered unqualified operating information, and the particle counter's operating state is unqualified. It can be understood that the current operating parameter information in this embodiment includes one or more of the flow rate information, stray light information, and light source operating current information. After design by technicians, the threshold corresponding to each operating information in the preset standard information is the qualified operating range of that operating information. The comparison between the current operating parameter information and the preset standard information corresponding to the current operating parameter information is to obtain the deviation value between the current operating parameter information and the preset standard information corresponding to the current operating parameter information. That is, the deviation value of the operating information in the current operating parameter information is the deviation value between the operating information in the current operating parameter information and the corresponding threshold in the preset standard information. In this embodiment, the deviation value includes one or more of the first, second, and third deviation values.

[0066] Furthermore, in order to make timely adjustments to particle counters that are not operating properly, after determining that the particle counter to be diagnosed is not operating properly, the following steps may also be included:

[0067] Step 41: Identify the control factors affecting the non-compliant operating information in the current operating parameter information;

[0068] Step 42: Determine the first adjustment cluster based on control factors;

[0069] Step 43: Adjust the particle counter to be diagnosed according to the first adjustment cluster to ensure that the particle counter to be diagnosed is operating in a qualified manner.

[0070] In this embodiment, the control factors affecting stray light information may include the selection of the cavity used by the particle counting sensor for stray light reception, the mirror group used for beam shaping, the coating for stray light absorption, and the structural design for trapping stray light; the control factors affecting flow rate information may include the selection of the power source for the pumped fluid and the setting of the pumping power magnitude; the control factors affecting the operating current of the light source may include the control of the light source main control board. It is understood that the first adjustment cluster includes a collection of various adjustment measures and methods for the control factors affecting the current operating parameter information, and also includes the specific adjustment content corresponding to the qualified operation of each operating parameter information after the unqualified operating information has been adjusted according to the control factors. This embodiment does not limit the adjustment measures / methods. For example, the adjustment measures / methods can be completed in one step; or the adjustment measures / methods can be step-by-step adjustments. For example, if the control factor is a parameter, the parameter adjustment of the control factor may be a step-by-step adjustment based on the control factors of the unqualified operating information in the current operating parameter information, or when the control factors of the operating parameter information are a combination of multiple factors, the adjustment of each factor combination is involved.

[0071] Furthermore, to enable the first adjustment cluster to better guide the particle counter, after adjusting the particle counter to be diagnosed according to the first adjustment cluster to ensure its qualified operation, the following steps may also be included:

[0072] The first adjustment cluster is updated using the non-compliant operation information and the adjustment content of the first adjustment cluster.

[0073] After the first adjustment cluster adjusts the particle counter to be diagnosed to ensure that the particle counter to be diagnosed is running in a qualified manner, the unqualified operation information in the current operation parameter information in step 41 and the specific adjustment content of the first adjustment cluster to ensure that the particle counter to be diagnosed is running in a qualified manner in step 43 are updated to the first adjustment cluster.

[0074] Furthermore, to provide a reference for the development and research of particle counters for new products, after determining that the particle counter to be diagnosed is malfunctioning, the following steps may also be included:

[0075] Step 61: Obtain the non-compliance operation information from the current operating parameter information of the particle counter to be diagnosed that is operating non-compliancely;

[0076] Step 62: Score the deviation value corresponding to the non-compliant operation information to obtain the first score result;

[0077] Step 63: Determine the second adjustment cluster based on the first scoring result for non-compliant operation information.

[0078] This embodiment addresses the deviation value of the non-compliant operating information of the current operating parameters corresponding to a particle counter undergoing non-compliant operation. It scores the deviation value and uses this score to determine the second adjustment cluster for the non-compliant operating information of the current operating parameters. In this embodiment, the non-compliant operating information corresponding to a particle counter undergoing non-compliant operation refers to the particle counter being determined to be non-compliant after comparing the current operating parameters with preset standard information, based on the impact of each score on the counting resolution of the particle counter corresponding to the non-compliant operating information of the current operating parameters. It can also be used to update the preset standard information of the current operating parameters corresponding to the target resolution of the particle counter, and can also be used to guide the development of new particle counters to obtain and confirm the current operating parameters corresponding to the target resolution and accuracy.

[0079] Furthermore, to improve the resolution and accuracy of the particle counter counting, after the second adjustment cluster that determines the unqualified operation information based on the first scoring result, the following steps may also be included:

[0080] Retrieve qualified operating information from the current operating parameter information;

[0081] The deviation values ​​corresponding to the qualified operation information are scored to obtain the second scoring result;

[0082] The second adjustment cluster is updated based on the second score results.

[0083] Because particle counters, as sensors, not only need to meet the standards for qualified operation but also require a high level of accuracy, scoring both qualified and unqualified particle counters helps to further improve accuracy. In this embodiment, the first and second adjustment clusters can also be used for correlation studies between operating parameter information and control factors.

[0084] That is, at least the deviation value between the current operating parameter information of the particle counter to be diagnosed that is operating incorrectly and the preset standard information is scored. For the particle counter to be diagnosed that is operating correctly, the deviation between its current operating parameter information and the preset standard value is also calculated. However, this deviation does not reach the first deviation value, the second deviation value, and the third deviation value mentioned above, but there is still a certain deviation. In this embodiment, the deviation value of both the qualified operation and the deviation value of the unqualified operation are scored, and the second adjustment cluster is updated using the score.

[0085] This embodiment can also input preset standard information, equipment information, control factors affecting non-compliant operating information in the current operating parameter information, the first adjustment cluster and the second adjustment cluster into the database.

[0086] The online diagnostic method for particle counters provided in this invention acquires the device information and current operating parameters of the particle counter to be diagnosed; determines the preset standard information corresponding to the particle counter to be diagnosed based on the device information; and compares the current operating parameters with the preset standard information to determine whether the particle counter to be diagnosed is operating correctly. This allows for remote acquisition, monitoring, and analysis of factors affecting the normal operation of the particle counter, enabling timely online real-time diagnosis. Furthermore, when any one of the flow rate information, stray light information, or light source operating current information is abnormal, the method for determining that the particle counter's operating status is unqualified can accurately diagnose the particle counter to be diagnosed. Additionally, by constructing a first adjustment cluster and adjusting the unqualified particle counters according to the first adjustment cluster, timely correction of unqualified particle counters can be achieved. Furthermore, by constructing a second adjustment cluster, based on the preset standard information of the current operating parameters corresponding to the target resolution of the particle counter, and also using this information to guide the development of new particle counters to achieve the target resolution and accuracy, the method provides a reference for the development and research of new product particle counters.

[0087] For a clearer understanding of this invention, please refer to the following details. Figure 2 Specifically, this can include: information A from the running parameter information (i.e. Figure 2 Taking the operating parameter A information as an example, the control factors affecting the operating parameter A information include, for example, control factor a1, control factor a2, and control factor a... n Based on the operating parameter information A and the preset standard information, the operating parameter A standard (the preset standard information corresponding to the operating parameter A information is...) Figure 2 The system compares the operating parameter A (standard) with the preset standard information to obtain the deviation between the operating parameter A information and the operating parameter A standard in the preset standard information. It then determines whether the operating parameter A information is qualified. If it is not qualified, the system adjusts the control factors a1, a2, and a3 based on the first adjustment cluster of the operating parameter A information. n Adjustments are made until operating parameter A is deemed acceptable, and the unacceptable operating parameter A, along with the adjusted control factors a1, a2, and a3, are then recorded. n The first adjustment cluster, which inputs the information of operating parameter A, forms a new first adjustment cluster with the information of operating parameter A.

[0088] Figure 3 exist Figure 2 Based on this, a diagnostic score is obtained by scoring according to the degree of difference (i.e., deviation value) between the information of operating parameter A and the standard of operating parameter A. For different types of particle counters, the diagnostic scores of each type of particle counter constitute the second adjustment cluster of the information of operating parameter A. Figure 4 Is Figure 3 Based on this, the degree of difference corresponding to the qualified result is also included in the diagnostic score, thus forming the second adjustment cluster of the operating parameter A information.
