[0043] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present application.

[0044] It should be understood that the "plurality" mentioned in this article refers to two or more. In the description of the embodiments of the present application, unless otherwise specified, " / " means or, for example, A / B can mean A or B; "and / or" in this article is only a description of the association relationship of associated objects, indicating that there can be three relationships, for example, A and / or B can mean: A exists alone, A and B exist at the same time, and B exists alone. In addition, in order to facilitate the clear description of the technical solutions of the embodiments of the present application, in the embodiments of the present application, the words "first", "second" and so on are used to distinguish between the same items or similar items with basically the same functions and effects. Those skilled in the art can understand that the words "first", "second" and so on do not limit the quantity and execution order, and the words "first", "second" and so on do not limit certain different

[0045] In addition, the terms "include" and "have" and any variations thereof are intended to cover non-exclusive inclusions. For example, a process, method, system, product or apparatus comprising a series of steps or units is not necessarily limited to those steps or units explicitly listed but may include other steps or units not explicitly listed or for these.

[0046] Most gas sensing devices collect and detect multiple gases such as CO2 and H2. Commonly used gas sensing devices collect gas by operating the fan inside the dust removal film to generate negative pressure around it, and then detect and process the collected gas. After research, the applicant found that long-term fan operation can easily lead to inaccurate detection results of the gas sensing equipment. According to further research by the applicant, due to the long-term operation of the fan, the total gas flow through the dust removal film of the gas sensing equipment continues to increase, and the dust particles in the air will gradually accumulate on the dust removal film. Due to the accumulation of dust particles, the negative pressure generated around the fan is not enough to prevent a sufficient amount of air from circulating around it, causing the gas sensing device (gas sensor inside) to produce errors in the measurement of the measured gas, exceeding the measurement accuracy range. Due to the insufficient accuracy of the gas sensing equipment, it will cause the control system to make misjudgments, resulting in greater losses.

[0047] Therefore, in view of the current situation that the reliability of the gas sensor device itself is ignored in the prior art, combined with the above analysis of the applicant, it can be determined that the state monitoring of the gas sensor device itself is particularly important. Therefore, the applicant proposes a state monitoring method of the gas sensor device for monitoring the state of the gas sensor device.

[0048] Figure 1 is a flow chart of a method for monitoring the state of a gas sensor device according to an embodiment of the present application. Figure 1 , the method includes the following processing steps.

[0049] S100: Acquire a concentration detection value representing the concentration of particulate matter inside the gas sensing device.

[0050] In this embodiment, obtaining includes obtaining through certain detection means, and also includes obtaining directly from a third party. The third party may be a special detection device.

[0051] S102: Determine the state of the gas sensor device according to the comparison result of the concentration detection value and the concentration reference range, wherein the concentration reference range is used to characterize the particle concentration inside the gas sensor device in a healthy state.

[0052] By adopting the method provided in this embodiment, a concentration detection value representing the concentration of particulate matter inside the gas sensing device can be obtained, and the state of the gas sensing device can be determined based on a comparison result between the concentration detection value and a concentration reference range.

[0053] In the related art, there is a method for determining or controlling the state of a gas sensing device based on a temperature and humidity sensor. However, the applicant has found that temperature and humidity are easily affected by the surrounding environment and have serious regional limitations, so the accuracy of the determination result of the state of the gas sensing device is poor. The method provided in this embodiment, which performs state detection based on particle size concentration, has higher accuracy and applicability and is less affected by the environment.

[0054] Optionally, in an implementation of this embodiment, the concentration detection value characterizing the concentration of particulate matter inside the gas sensing device can be obtained in the following manner: first, light is emitted inside the gas sensing device (for example, laser is emitted) so that the particulate matter inside the gas sensing device scatters the light to generate scattered light; then, the intensity of the scattered light is detected; finally, the concentration detection value is determined according to the intensity of the scattered light. With this implementation, the concentration of particulate matter can be accurately determined by the intensity of scattered light, thereby ensuring the accuracy and reliability of state monitoring.

[0055] Optionally, in an implementation of this embodiment, the concentration detection value characterizing the concentration of particles inside the gas sensing device may be obtained in the following manner: using a laser detector to detect the concentration detection value of the concentration of particles inside the gas sensing device. For example, a laser sensor is used to detect the concentration of particles in the internal channel of a dust removal film. When the laser is irradiated on suspended particles in the air, the particles scatter the laser, and the scattered light is collected by the optical receiving system of the photodetector or the laser sensor within a specific angle range, and then the concentration of particles is obtained through photoelectric conversion and data processing.

[0056] Exemplarily, the laser sensor may include the following structure.

[0057] Laser source: produces a stable laser beam, usually low-power semiconductor lasers are used because they are small, efficient and relatively low cost.

[0058] Sampling chamber: is an enclosed space where the air sample is guided through the laser beam. The sampling chamber is designed with special airflow channels to ensure that the air sample passes through the laser beam evenly.

[0059] Photodetectors: Located on one or both sides of the laser beam to capture scattered light. Depending on the design, single or multiple detectors may be used to obtain more comprehensive data.

[0060] Signal processor: Amplifies, filters and digitizes the received scattered light signal, and then applies a specific algorithm to calculate the concentration of particulate matter.

[0061] The main process of using laser sensors to detect particle concentration includes:

[0062] Light scattering: When a laser beam passes through air containing particles, the particles will scatter the laser. The intensity of the scattered light is related to the size, shape and number of particles. Generally speaking, the larger the particles, the stronger the scattered light; the more particles there are, the stronger the total scattered light.

[0063] Detecting scattered light: The sensor is equipped with a photoelectric converter (such as a photodiode) to receive scattered light and convert it into an electrical signal. The intensity of the electrical signal reflects the intensity of the scattered light and, in turn, the concentration of the particles.

[0064] Data processing: By processing the received electrical signals through algorithms, the number concentration (number of particles per unit volume) or mass concentration (mass of particles per unit volume) of particles can be calculated. Different particle sizes have different effects on scattered light, so advanced sensors can also distinguish particles of different sizes and give the distribution of each size segment.

[0065] Optionally, in an implementation of this embodiment, as Figure 2 As shown, the gas sensing device is internally provided with multiple ( Figure 2 In this case, when the laser detector 1 is used to detect the concentration detection value of the particle concentration inside the gas sensing device, the concentration detection value can be calculated (for example, by averaging, median value, etc.) based on the detection results of the multiple laser detectors.

[0066] Reference Figure 2 In this implementation, the gas sensing device is a shell having a cavity inside, and a support 3 for mounting or fixing a laser sensor 1 is arranged in the cavity. A plurality of laser sensors 1 are arranged on the support 3 at intervals and opposite to the dust removal film 4, and are used to emit lasers in the direction of the dust removal film 4. A gas sensor 2 is installed or arranged on the inner wall of the shell for gas detection.

[0067] Optionally, in an implementation of this embodiment, the state of the gas sensor device includes at least one of healthy, subhealthy and unhealthy, wherein healthy means that the detection result of the gas sensor device is reliable, unhealthy means that the detection result of the gas sensor device is unreliable, and subhealthy means that the detection result of the gas sensor device is about to be unreliable.

[0068] In this implementation, the following method can be used to determine the state of the gas sensing device based on the comparison result between the concentration detection value and the concentration reference range: if the concentration detection value is within the concentration reference range, the state of the gas sensing device is healthy; if the concentration detection value is not within the concentration reference range, the state of the gas sensing device is unhealthy; if the concentration detection value is within the concentration reference range and the difference between the concentration detection value and the minimum value of the concentration reference range is less than a preset value, the state of the gas sensing device is sub-healthy.

[0069] Wherein, when the state of the gas sensor device is sub-healthy, a warning signal indicating that the state of the gas sensor device is sub-healthy is issued. For example, the control warning module issues the warning signal to remind the user in advance before the gas sensor device fails.

[0070] Optionally, in an implementation of this embodiment, the state of the gas sensor device includes the health of the gas sensor device. The health indicates the reliability of the detection result of the gas sensor device. The higher the health, the higher the reliability of the detection result.

[0071] In this implementation, the following method can be used to determine the state of the gas sensor device based on the comparison result between the concentration detection value and the concentration reference range: determine the health of the gas sensor device based on the position of the concentration detection value within the concentration reference range, wherein the closer the position of the concentration detection value within the concentration reference range is to the maximum value of the concentration reference range, the lower the health of the gas sensor device.

[0072] Exemplarily, the concentration reference range includes multiple concentration reference sub-ranges, each concentration reference sub-range corresponds to a different health level, and different health levels correspond to different precision errors. For example, the concentration reference range may include 10 continuous but non-overlapping concentration reference sub-ranges, the difference between the maximum and minimum values ​​of the 10 concentration reference sub-ranges is the same, and when the concentration values ​​are arranged from small to large, the precision errors of the gas detection results of the gas sensing device are arranged from small to large. For example, the health level of the first reference sub-range is 100% (the corresponding precision error is 0), the health level of the second reference sub-range is 99% (the corresponding precision error is ±0.05%), the health level of the third reference sub-range is 98% (the corresponding precision error is ±0.1), ... The health level of the tenth reference sub-range is 91% (the corresponding precision error is ±0.45%).

[0073] Among them, when the health of the gas sensor device is determined to be 95% based on the detected concentration detection value, it can be considered as the critical value of the gas sensor device being about to fail. If the health of the gas sensor device is less than 95%, it is considered that the accuracy error of the gas sensor device is too large. At this time, the gas sensor device can be considered to have failed, and the control system can issue a control instruction to issue a warning.

[0074] Optionally, in an implementation of this embodiment, the actual detected gas concentration detection value may be corrected according to the accuracy error to obtain a more accurate gas concentration estimation value. 估算 =(1+p)·A 实测 Among them, A 估算 represents the estimated value of gas concentration, p represents the accuracy error, A 实测 It represents the gas concentration detection value obtained by actual detection. Taking the health level of 99% and the corresponding accuracy error of ±0.05% as an example, the specific value of p can be 0.03% or -0.02%, etc. Its range value or specific value can be determined according to experiments and will not be described in detail here.

[0075] By adopting this implementation, the health of the gas sensor device can be quantified, thereby more objectively and accurately measuring the state of the gas sensor device. The detection value of the gas sensor device can also be estimated or corrected according to the precision error of the gas sensor device to obtain an estimated value or estimated range that is closer to the true value.

[0076] Optionally, in an embodiment of the present application, after S104, when it is detected that the state of the gas sensor device is unhealthy, or when the health level of the gas sensor device does not meet the requirements, the warning module can be controlled to issue a reminder. The warning module can be a module that uses sound, light, electricity, etc. to issue a reminder, such as a display screen, a buzzer, etc.

[0077] Figure 3 is a system block diagram of a gas sensing device according to an embodiment of the present application. Figure 3 As shown, the gas sensing device includes a control module, a CO2 gas detection module, a H2 gas detection module, a temperature and humidity detection module, a laser monitoring module X and a laser monitoring module Y, and an alarm output module. Among them, the CO2 gas detection module and the H2 gas detection module can be collectively referred to as a gas sensor. The gas sensor can include multiple sensors for detecting the concentration of different gases.

[0078] Among them, the control module is communicated with the CO2 gas detection module, the H2 gas detection module, the temperature and humidity detection module, the laser monitoring module X and the laser monitoring module Y and the warning output module to obtain data and send control instructions when necessary, for example, to control whether the functions of each module are turned on or off.

[0079] The CO2 gas detection module and the H2 gas detection module are used to detect the concentrations of CO2 and H2 respectively, and send the detection results to the control module for storage and processing. The temperature and humidity detection module is used to detect the temperature and humidity inside the gas sensing device, and send the detection results to the control module for storage and processing. For example, the control module corrects the concentrations of CO2 and H2 according to the temperature and humidity, and controls the operation of the laser monitoring modules X and Y according to the temperature and humidity.

[0080] The laser monitoring module X and the laser monitoring module Y are both used to detect the particle size concentration inside the gas sensing device, but the detection positions are different. In this way, the final particle size concentration detection value can be comprehensively determined (for example, the average value is calculated) based on the detection results of the two.

[0081] The warning module is used to issue a warning to remind or display the status of the gas sensing device under the control of the control module.

[0082] Figure 4 FIG. 1 is a flow chart of a method for monitoring the state of a gas sensor device according to an embodiment of the present application. Figure 4 As shown, the method includes the following processing steps.

[0083] Laser sensor collects data. Specifically, the present invention uses a laser sensor to detect the concentration of particles in the internal channel of the dust removal film. When the laser is irradiated on the suspended particles in the air, the particles will scatter the laser, and the scattered light is collected by the optical receiving system of the laser sensor within a specific angle range.

[0084] Afterwards, the data is uploaded to the control module. It should be noted that the control module can pre-store the aforementioned concentration reference range [y01, y02). Among them, y01 can be understood as the average of the particle concentration values ​​detected when the gas sensor device is used for the first time or the first few times, and y02 can be understood as the particle concentration of the gas sensor device when it fails (unreliable) or is about to fail. Both values ​​can be obtained based on experiments or actual monitoring and combined with artificial regulations (for example, artificial regulations on when the gas sensor device fails), and their values ​​are not specifically limited here.

[0085] After that, the collected data is averaged (y1). That is, the average value y1 is obtained by determining the average value of the collected data.

[0086] Afterwards, a data comparison is performed to determine whether y1∈[y01, y02) is satisfied. If satisfied, it is considered that the accuracy of the gas sensing device meets the requirements and the detection result is reliable, and the process continues to return to the step of laser sensor data collection to facilitate continuous monitoring of the status of the gas sensing device. If not satisfied, an alarm can be issued under the control of the control module to remind the staff to pay attention to the real-time status of the sensor and ensure the reliability and stability of the sensor. Among them, if y1 is greater than or equal to y02, it can be considered that the gas sensing device is in an unhealthy (or failed) state. Of course, in other embodiments of the present application, the degree of unreliability of the gas sensing device can also be determined based on the degree to which y1 exceeds y02. The greater the degree to which y1 exceeds y02, the higher the unreliability of the gas sensing device, and the more insufficient the gas flow in the internal channel of the dust removal film of the gas sensing device.

[0087] Since the long-term operation of the sensor will cause impurities to be adsorbed on the surface of the dust removal film, the air flow inside the dust removal film will change differently, causing the sensor to "fail". This method uses a set of (two) laser sensors to detect the concentration of particles inside the dust removal film, and compares the initial memory concentration through the control module to determine the real-time state of the internal channel of the dust removal film in advance to avoid losses caused by sensor "failure". The detection data of the laser sensor can also be compared with the memory data to determine the accuracy error of the gas sensing equipment, and the detection results and accuracy errors can be fed back in real time.
