Description

Technical Field

[0001] The present invention relates to the technical field of environmental monitoring, and in particular to a sampling effectiveness monitoring method and an intelligent sampling bottle. Background Art

[0002] Currently in the field of water quality laboratory monitoring (testing), water samples are generally collected and transported in ordinary bottles, which are then placed in ordinary frames or insulated boxes with refrigeration functions for transportation (the water sample transportation link refers to the process from sample collection on site to handover to the laboratory). This method makes it difficult to effectively monitor the length of time, storage temperature and human factors that interfere with the water samples during transportation.

[0003] If ordinary bottles and ordinary frames are used, the duration of the transportation process needs to be recorded manually or by an external system (such as a dedicated sampling APP). The water sample storage temperature is generally not recorded. The water sample bottle can be opened manually during transportation, and there is a risk of changing the sample liquid.

[0004] The storage temperature of water samples can be recorded by the temperature recorder of the incubator, but when the samples are handed over, the person receiving the samples needs to use special tools to read the temperature data of the entire transportation process, which is troublesome and prone to errors. In order to prevent artificial replacement of sample liquid, a one-time seal or signature is generally used to prevent the incubator from being opened, but there is also the possibility of water sample distortion.

[0005] Moreover, in the existing technology, the supervision of the effectiveness of water samples only focuses on the transportation of water samples. There is a lack of relevant records of water quality parameters during the sampling process, and it is impossible to ensure that the most representative sample liquid is collected.

[0006] Therefore, there is an urgent need for a monitoring method for the effectiveness of sampling, which can record and judge the effectiveness of the entire process of water sample collection, transportation, and delivery, ensure the collection of the most representative water samples, and log the entire process of water sample collection, transportation, and delivery to ensure the effectiveness, representativeness, and timeliness of the water samples, thereby improving the accuracy and traceability of the test results. Therefore, the whole process monitoring measures are taken to ensure quality control from sampling to delivery inspection. Summary of the invention

[0007] On the one hand, the present invention provides a sampling validity monitoring method to solve the technical problems that there is a hidden danger of human intervention in samples, lack of traceability, and difficulty in ensuring the accuracy of test results during the period from sampling completion to delivery for testing.

[0008] The technical solution adopted by the present invention is as follows:

[0009] A sampling effectiveness monitoring method comprises the steps of:

[0010] After completing the sampling and before the samples are delivered for testing, obtain real-time testing information on the effectiveness of the smart sampling bottle;

[0011] The samples in the smart sampling bottle are compared for effectiveness according to the real-time effectiveness detection information and preset sample effectiveness judgment conditions, and finally the sample effectiveness is judged according to the comparison results.

[0012] Furthermore, the real-time validity detection information is stored in the smart sampling bottle. When delivering samples, the validity of the samples in the smart sampling bottle is compared by reading the real-time validity detection information stored in the smart sampling bottle and the preset sample validity judgment conditions. Finally, the validity of the samples is judged according to the comparison results.

[0013] Furthermore, the real-time validity detection information is transmitted to the management platform via wireless communication. The management platform performs validity comparison on the samples in the smart sampling bottle according to the received real-time validity detection information and preset sample validity judgment conditions, and finally judges the validity of the samples according to the comparison results.

[0014] Furthermore, the effectiveness comparison of the samples in the smart sampling bottle is performed according to the effectiveness real-time detection information and the preset sample effectiveness judgment conditions, and finally the effectiveness of the samples is judged according to the comparison results. Specifically, the steps include:

[0015] Obtaining the sample storage time, where the sample storage time is the difference between the sample delivery time and the sampling time;

[0016] If the sample storage time is longer than the preset sample storage period, the current sample is determined to be an expired sample.

[0017] Furthermore, the effectiveness comparison of the samples in the smart sampling bottle is performed according to the effectiveness real-time detection information and the preset sample effectiveness judgment conditions, and finally the effectiveness of the samples is judged according to the comparison results. Specifically, the steps include:

[0018] Obtain the sample storage temperature recorded in real time during the sample transportation process;

[0019] Record the sample temperature changes in real time and obtain the duration that the sample storage temperature exceeds the allowable range;

[0020] If the sample storage temperature exceeds the allowable range for a period of time exceeding the set threshold,

[0021] or,

[0022] When the proportion of the duration in the total duration of the transportation link is greater than the set threshold, the current sample is determined to be an invalid sample.

[0023] Furthermore, the effectiveness comparison of the samples in the smart sampling bottle is performed according to the effectiveness real-time detection information and the preset sample effectiveness judgment conditions, and finally the effectiveness of the samples is judged according to the comparison results. Specifically, the steps include:

[0024] After the sampling is completed and before the sampling is delivered for testing, detect whether the cover of the smart sampling bottle has been disassembled, and obtain the corresponding detection signal;

[0025] The authenticity of the corresponding sampling is determined according to the corresponding detection signal: if there is disassembly, it is prompted that the cover of the corresponding smart sampling bottle is illegally opened, and the current sample is determined to be an invalid sample; otherwise, it is prompted that the corresponding smart sampling bottle is in normal working condition.

[0026] Furthermore, the step of determining the authenticity of the corresponding sample according to the corresponding detection signal specifically comprises the steps of:

[0027] Real-time detection of the pressure value between the cover and the cup body, and acquisition of corresponding detection signals;

[0028] If the detected pressure value between the cover and the cup is lower than the set threshold, it is prompted that the cover of the corresponding smart sampling bottle is illegally opened, and the current sample is determined to be an invalid sample;

[0029] Otherwise, it indicates that the corresponding intelligent sampling bottle is in normal working condition.

[0030] Furthermore, the step of determining the authenticity of the corresponding sample according to the corresponding detection signal specifically comprises the steps of:

[0031] Real-time detection of the relative displacement between the cover and the cup body, and acquisition of corresponding detection signals;

[0032] If there is a relative displacement between the cover and the cup, it is prompted that the cover of the corresponding smart sampling bottle is illegally opened, and the current sample is determined to be an invalid sample;

[0033] Otherwise, it indicates that the corresponding intelligent sampling bottle is in normal working condition.

[0034] Furthermore, performing a validity comparison on the samples in the smart sampling bottle according to the validity real-time detection information and the preset sample validity judgment conditions, and finally judging the sample validity according to the comparison results also includes the steps of:

[0035] Obtain the test results of the conductivity probe in the smart sampling bottle in real time;

[0036] If the conductivity probe detects that the conductivity or liquid level state of the sample in the smart sampling bottle changes, the current sample is determined to be a failed sample.

[0037] Another aspect of the present invention further discloses an intelligent sampling bottle, which is applied to the sampling effectiveness monitoring method. The intelligent sampling bottle comprises:

[0038] A sampling bottle, wherein a control module and a plurality of environment sensing sensors are installed on the sampling bottle, wherein the environment sensing sensors are used to detect relevant parameter index data of the surrounding water environment, and the control module is used to store the relevant parameter index data detected by the environment sensing sensors.

[0039] The present invention has the following beneficial effects:

[0040] The sampling validity monitoring method of the present invention obtains real-time validity detection information of the smart sampling bottle by recording the entire process of sampling, transportation, and sample delivery and testing; and judges the validity of the sample in the smart sampling bottle based on the comparison result of the real-time validity detection information and the preset sample validity judgment condition, thereby realizing comprehensive and automatic monitoring of the validity of the sample from the completion of sampling to the delivery and testing, ensuring the validity, representativeness, timeliness and traceability of the sample, as well as the reliability of the monitoring data, avoiding the hidden dangers of sample fraud or failure due to human intervention, thereby ensuring the accuracy and reliability of the final test result of the sample.

DETAILED DESCRIPTION

[0057] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0058] At present, there is a certain time difference between the completion of sampling and the delivery of samples for testing. In order to ensure the accuracy of subsequent test results, it is necessary to ensure the validity of samples, such as the authenticity of samples and the validity of sample quality. Authenticity is mainly to prevent samples from being replaced during transportation, and the validity of sample quality is after the completion of sample collection. Its characteristics often change accordingly with time, temperature, pressure, mode of transportation and other factors. Once the sample is replaced or the quality fails, it will directly lead to the accuracy of subsequent test results, and it will be impossible to provide scientific and accurate monitoring data for environmental monitoring and protection. In order to ensure the correctness of subsequent test results, the changes in the sample quality must be controlled within a reasonable range before the completion of sampling and delivery for testing, so as to provide samples that meet the requirements for subsequent testing and ensure the accuracy of the test results. At present, due to the lack of corresponding monitoring measures, the sample operation from the completion of sampling to the delivery of testing is mainly completed manually. During the transportation process, the validity of the samples will inevitably be affected due to subjective or negligent reasons, which makes the validity, representativeness and timeliness of the samples in the transportation process have great risks. It is difficult to guarantee the supervision and control of the samples 100%. Therefore, ensuring the validity of the samples from the completion of sampling to the delivery of testing is of great practical significance for the accuracy, scientificity and traceability of the subsequent test results.

[0059] Based on the above objective factors and actual needs, Figure 1 The preferred embodiment of the present invention provides a sampling validity monitoring method, comprising the steps of:

[0060] S1. After completing the sampling and before the sample is delivered for testing, obtain the real-time detection information of the effectiveness of the smart sampling bottle;

[0061] S2. Performing a validity comparison on the samples in the smart sampling bottle according to the real-time validity detection information and preset sample validity judgment conditions, and finally judging the sample validity according to the comparison results.

[0062] This embodiment provides a sampling validity monitoring method, which first obtains real-time validity detection information of the smart sampling bottle after the sampling is completed and before the sample is delivered for inspection, wherein the real-time validity detection information may include sampling time information, real-time temperature information, sampling location information, sample transportation trajectory information, smart sampling bottle posture and vibration information and other detection information related to sample validity. The above real-time validity detection information can reflect the relevant status of the sample during transportation. For example, the sampling time information and sampling location information are used to determine whether the sample is collected at a designated location and time to ensure the representativeness of the sample; the smart sampling bottle posture and vibration information can reflect whether there is abnormal placement, vibration or structural damage during sample transportation. After obtaining relevant real-time validity detection information, this embodiment will judge the validity of the sample in the smart sampling bottle according to the comparison result of the real-time validity detection information and the preset sample validity judgment condition. The relevant validity judgment condition can set the type of threshold in advance according to the detection needs and the characteristics of the sample, such as temperature threshold, time threshold, smart sampling bottle acceleration threshold, pressure threshold, etc., as the comparison standard for judging the validity of the sample. The setting of the above thresholds can be comprehensively set according to factors such as sample type, detection item, current climate, transportation distance, transportation means, storage conditions, detection conditions and requirements. In other words, the setting of relevant thresholds is not a one-size-fits-all method. It is not fixed, but it is necessary to determine which threshold to set and how to set the threshold range according to the current sample detection target and related working conditions, so as to ensure the authenticity and reliability of the final inspection data. Different types of samples may have different failure factors. For example, for some samples with poor chemical stability, they are more sensitive to temperature and time, so their validity judgment conditions are mainly based on temperature threshold and time threshold. For some samples with higher temperature requirements, they are more sensitive to temperature, so their validity judgment conditions are mainly based on temperature threshold; and for some samples with higher stability requirements, they are more sensitive to vibration, so their validity judgment conditions are mainly based on acceleration threshold. In other words, different samples will have different validity judgment conditions. At the same time, the types of samples, sample detection items and targets, and related working conditions will also affect the value ranges of the above thresholds. Therefore, on the one hand, when obtaining the real-time detection information of effectiveness, the intelligent sampling bottle will make targeted selections according to the sample type, and only obtain part of the real-time detection information of effectiveness that has an impact on the effectiveness of the current sample. Other real-time detection information of effectiveness that is irrelevant to the effectiveness of the current sample will be ignored, thereby improving the efficiency of obtaining the real-time detection information of effectiveness. When saving the relevant real-time detection information of effectiveness locally or sending it to the management platform, the amount of data storage and the amount of data transmission can be effectively reduced, so that data can be obtained on demand, avoiding wasting precious system operating resources on irrelevant data, and ensuring the efficient operation of the entire effectiveness monitoring process.On the other hand, the management platform can store in advance a database that characterizes the correspondence between sample types and validity judgment conditions. When the management platform obtains the sample type based on relevant information, it can automatically select the corresponding validity judgment condition to judge the validity of the current sample. The extracted validity judgment condition matches the real-time validity detection information obtained on demand by the above-mentioned smart sampling bottle, which can improve the judgment efficiency and achieve on-demand extraction of validity judgment conditions. In other words, this embodiment can improve the efficiency of data acquisition and sample validity judgment by organically combining the sampling end to obtain data on demand and the management platform to extract validity judgment conditions on demand, thereby improving the operating efficiency of the entire sampling validity monitoring method.

[0063] The database characterizing the correspondence between sample types and validity judgment conditions can be stored in advance as basic data in a management platform that communicates wirelessly with the smart sampling bottle. When it is necessary to judge the validity of the sample in the smart sampling bottle, the management platform will retrieve the validity judgment conditions and compare them with the received real-time validity detection information. Finally, based on the comparison result, the sample can be judged as a valid sample or an invalid sample. The entire judgment process is carried out automatically without human intervention, and the relevant detection data is true and reliable.

[0064] like Figures 8 to 12 As shown, the smart sampling bottle used in the present invention includes a sampling bottle 10, on which a control module 11 and a plurality of environment sensing sensors 12 are installed. The environment sensing sensor 12 is used to detect relevant parameter index data of the surrounding water environment, and the control module 11 is used to store the relevant parameter index data detected by the environment sensing sensor 12. Among them, the environment sensing sensor 12 includes a water pressure sensor for detecting the water depth at the location of the sampling bottle 10, a temperature sensor for detecting the temperature of the water sample, a conductivity sensor for detecting the conductivity of the water sample, a flow sensor for detecting the flow of the water environment, a pH sensor for detecting the pH value of the water sample, an ORP sensor for detecting the ORP of the water sample, a dissolved oxygen sensor for detecting the dissolved oxygen concentration in the water sample, a turbidity sensor for detecting the turbidity of the water sample, a microphone, and at least one of a video acquisition device.

[0065] It can be understood that the smart sampling bottle of this embodiment can monitor the temperature data, flow data, pH value data, ORP sensor, dissolved oxygen sensor, conductivity data, etc. of the surrounding water environment over a period of time by installing multiple environmental sensing sensors 12 on the sampling bottle 10, so as to conduct long-term on-site monitoring of relevant water quality parameters of the surrounding water environment, and store the monitoring data through the control module 11. When it is necessary to obtain the monitoring data, the sampling bottle 10 can be picked up to read the monitoring data stored in the control module 11. In addition, the monitoring carrier is a bottle, which does not need to be fixed at the sampling point, and can be flexibly set according to the monitoring needs, and has a wide range of applications.

[0066] It can be understood that the sampling bottle 10 is also equipped with a wireless communication module 16 electrically connected to the control module 11, and the wireless communication module 16 is used to wirelessly transmit the relevant parameter index data detected by the environmental sensing sensor 12 to the remote management platform or management terminal. For example, the wireless communication module 16 includes a 3G / 4G / 5G module, a NB-IOT module, an eMTC module, a LoRa module or a Sigfox module, so that the detection parameters can be remotely transmitted to the remote management platform in real time; or, the wireless communication module 16 is an NFC module, a Bluetooth module, a Wi-fi module or a Zigbee module, and the staff can bring the management terminal to the site and establish a wireless connection with the wireless communication module 16, so as to wirelessly read the monitoring data stored in the control module 11. In addition, in other embodiments of the present invention, the wireless communication module 16 can be omitted, and after the sampling bottle 10 is picked up from the water environment, the monitoring data in the control module 11 can be directly read through the interface using the management terminal.

[0067] Specifically, the sampling bottle 10 includes a bottle cap 101 and a bottle body 102, wherein the bottle cap 101 and the bottle body 102 are designed in an integrated manner or in a separate manner, and a water inlet pipeline 103 is provided on the bottle cap 101, and a water inlet valve 104 is provided on the water inlet pipeline 103, and the water inlet valve 104 is electrically connected to the control module 11, and the control module 11 is also used to control the state of the water inlet valve 104. The control module 11 can control the state of the water inlet valve 104 according to a preset control logic, for example, when it is monitored that at least one of the following conditions is that the water sample temperature exceeds the standard, the sewage outlet starts to drain, the drainage volume exceeds the standard, the water quality parameter changes, and the water quality parameter index exceeds the preset value, the control module 11 controls the water inlet valve 104 to open, and since the pressure in the bottle body 102 is less than the atmospheric pressure, the water sample can be passed into the bottle body 102 through the water inlet pipeline 103, thereby realizing automatic sampling based on water environment supervision. The water inlet valve 104 may be a solenoid valve or an electric valve, that is, the control module 11 may control the water inlet valve 104 to open or close or adjust the opening degree of the water inlet valve 104 .

[0068] It can be understood that the sampling bottle 10 is also provided with a timer 13 electrically connected to the control module 11. The control module 11 controls the timer 13 to record the sampling time while controlling the water inlet valve 104 to open, or when the environmental perception sensor 12 transmits the detection data to the control module 11, the control module 11 controls the timer 13 to record the detection time, and transmits the relevant parameter index data, sampling time and / or detection time detected by the environmental perception sensor 12 to the remote management platform or management terminal through the wireless communication module 16. In addition, when the wireless communication module 16 is not included, the control module 11 can associate the sampling time and / or detection time with the relevant parameter index data detected by the environmental perception sensor 12 for storage, and then read them later.

[0069] The control module 11 and the wireless communication module 16 are arranged in a separate chamber in the bottle cap 101 or in the bottle body 102, and the environment sensor 12 is arranged on the outer wall of the bottle cap 101 and / or the bottle body 102. In addition, the environment sensor 12 is located on a side close to the water inlet pipe 103, so as to ensure that the environment sensor 12 can contact with water to monitor the water environment. At the same time, since the environment sensor 12 is arranged on a side close to the water inlet pipe 103, the weight of the side where the water inlet pipe 103 is located is increased, ensuring that the water inlet of the water inlet pipe 103 is located below the liquid surface for easy sampling. When the sampling bottle 10 is a floating type monitored sampling, the wireless communication module 16 needs to be set on the side away from the water inlet pipe 103, so as to ensure that the wireless communication module 16 can maintain real-time communication with the remote management platform during the floating and sampling process; or, when the sampling bottle 10 is a fixed type monitored sampling, for example, the sampling bottle 10 is installed on a fixed frame, it is necessary to lengthen the antenna of the wireless communication module 16 to ensure that the antenna of the wireless communication module 16 is pulled out of the water surface or near the water surface to transmit signals.

[0070] In addition, as a preferred embodiment, an air outlet pipeline 106 is further provided on the side of the bottle cap 101 opposite to the water inlet pipeline 103, and the control module 11 controls the sampling state by controlling the state of the water inlet valve 104. Since the air outlet pipeline 106 is provided on the side opposite to the water inlet pipeline 103, when the sampling bottle 10 is put into a water environment, the air outlet pipeline 106 is always connected to the atmosphere, and there is a certain pressure difference between the water inlet pipeline 103 and the air outlet pipeline 106, so that the water sample is automatically collected from the water inlet pipeline 103 to the bottle body 102, and the control module 11 can control the water sample collection state by controlling the state of the water inlet valve 104. Optionally, a one-way valve is provided on the water inlet pipeline 103 and the air outlet pipeline 106.

[0071] As further preferred, an outlet valve 107 is provided on the outlet pipeline 106, and the outlet valve 107 is electrically connected to the control module 11. The control module 11 is also used to control the state of the outlet valve 107. The control module 11 controls the sampling state by controlling the states of the water inlet valve 104 and the outlet valve 107. For example, the control module 11 can adjust the pressure difference between the water inlet pipeline 103 and the outlet pipeline 106 by controlling the states of both the water inlet valve 104 and the outlet valve 107, thereby controlling the sampling state.

[0072] In addition, as an option, the sampling bottle 10 can be designed to have multiple areas with different average densities, the water inlet pipeline 103 is located in the area with the highest average density of the sampling bottle 10, and the air outlet pipeline 106 is located in the area with the lowest average density. After the sampling bottle 10 is placed at the sampling point, the water inlet pipeline 103 is located below the liquid surface, and the air outlet pipeline 106 is located above the liquid surface. When the control module 11 controls the water inlet valve 104 to open, the water inlet pipeline 103 can automatically pass the water sample into the bottle body 102. Among them, the multiple areas with different average densities can be formed by processing the manufacturing material and / or shape of the sampling bottle 10 itself; or by arranging a counterweight structure inside and / or outside the sampling bottle 10 to form the multiple areas with different average densities, for example, a counterweight block is added to the sampling bottle 10, and the water inlet pipeline 103 is arranged near the counterweight block, so that the water inlet pipeline 103 is located in the area with the highest average density of the sampling bottle 10; or by arranging an air flotation structure inside and / or outside the sampling bottle 10 to form the multiple areas with different average densities. As the water sample gradually enters the bottle body 102, the overall density distribution of the sampling bottle 10 changes, so the posture of the sampling bottle 10 also changes. When the water inlet pipe 103 changes to above the liquid level, sampling stops automatically. After sampling is completed, the water inlet pipe 103 and the air outlet pipe 106 are both higher than the liquid level in the bottle body 102. In addition, when the pressure difference between the water inlet pipe 103 and the air outlet pipe 106 is zero, sampling stops automatically, and automatic sampling and automatic stop sampling can be achieved without manual sampling operations, and the structure is simple and the manufacturing cost is low. The overall average density of the sampling bottle 10 after sampling is completed is still less than the density of the surrounding water environment, so the sampling bottle 10 after sampling is still floating on the liquid surface. Therefore, the average density of different areas of the sampling bottle 10 can be designed according to the sampling volume requirements of the water sample, so that the automatic sampling volume of the sampling bottle 10 meets the requirements.

[0073] According to the requirements of the sampling volume of the water sample, the average density of different areas of the sampling bottle 10 is designed so that the automatic sampling volume of the sampling bottle 10 meets the requirements. For example, the average density of the area near the water inlet pipe 103 is designed to be no less than the density of the water sample to be tested, and the average density near the air outlet pipe 106 is no greater than the density of the water sample to be tested. Alternatively, the average density of the area near the water inlet pipe 103 is less than the density of the water sample to be tested, but with the structural design connected thereto, after the sampling bottle 10 is placed on the sampling liquid surface, there is a pressure difference between the inner cavity of the sampling bottle 10 and the liquid surface. After the area near the water inlet pipe 103 contacts the liquid surface, the water sample to be collected is partially emptied, so that part or all of the water inlet pipe 103 is located below the liquid surface, and it can be ensured that the water sample can smoothly enter the interior of the sampling bottle 10 under the pressure difference. For example, the average density of the water inlet pipe 103 area is lower than the density of the water sample to be tested. A structure or component providing pressure is externally connected to the area, forcing the water sample to be collected to be partially emptied after being placed at the sampling point and the area near the water inlet pipe 103 contacts the liquid surface. This causes a pressure difference between the inner cavity of the sampling bottle 10 and the liquid surface.

[0074] Therefore, there is no clear boundary between the average density of the area near the water inlet pipe 103 and / or the air outlet pipe 106 and the density of the water sample to be collected. In the specific implementation process, it can be achieved by combining flexible structures. For example, the area where the average density of the water inlet pipe 103 is smaller than the density of the water sample to be collected is processed into a wedge shape or a cone shape, and the sampling bottle 10 is placed at the sampling point. After maintaining balance, part or all of the water inlet pipe 103 is located below the liquid surface.

[0075] The above description is based on only several preferred embodiments of the present invention. However, for those skilled in the art, based on the above disclosure, other similar structures different from this can be designed based on the relationship between the regional density of the water inlet pipeline 103 and the water sample to be collected. For example, by connecting an auxiliary structure to the sampling bottle 10, power is provided to the sampling bottle 10, so that when the sampling bottle 10 is in a balanced position, part or all of the water inlet pipeline 103 is ensured to be below the liquid surface. This can be appropriately adjusted according to specific circumstances. Regarding the specific fixed position relationship or other structural shapes that achieve the same function, this should be easy for those skilled in the art to conceive, so it will not be repeated here.

[0076] Necessary explanation is given about the average density of the sampling bottle 10: in the empty state, the average density of the entire sampling bottle 10 is the ratio of the mass of the sampling bottle 10 to the volume of the sampling bottle 10 itself; in the sampling state, the average density is the ratio of the sum of the mass of the sampling bottle 10 and the water sample collected inside to the volume of the sampling bottle 10 itself. Preferably, the average density of the entire sampling bottle 10 is not greater than the density of the water sample to be collected. In this way, it can be ensured that the entire sampling bottle 10 can float on the surface of the water sample to be collected during and after the sampling process.

[0077] In addition, the sampling bottle 10 can be a plurality of interconnected cavities, and / or a plurality of independent cavities. Thus, by controlling the valve, a sampling terminal can take samples from multiple sampling points; or a controller can achieve sampling at the same sampling point, and / or multiple sampling points at different time periods.

[0078] Optionally, the overall average density of the sampling bottle 10 before sampling is less than the density of the water sample. After the sampling bottle 10 is placed at the sampling point, the water inlet pipe 103 is located in the area with the highest average density of the sampling bottle 10, and the water inlet pipe 103 first sinks below the liquid surface, so that the water sample is collected from the water inlet pipe 103 into the bottle body 102, and the gas in the bottle body 102 is discharged to the outside from the gas outlet pipe 106. Optionally, the gas outlet pipe 106 also sinks below the liquid surface, or the gas outlet pipe 106 does not sink below the liquid surface. When the liquid level in the sampling bottle 10 is flush with the liquid level at the collection point, sampling will automatically stop. As the water sample gradually enters the bottle body 102, the overall density distribution of the sampling bottle 10 changes, so the posture of the sampling bottle 10 also changes, and when the water inlet pipe 103 changes to above the liquid surface, sampling will automatically stop. After the sampling of the sampling bottle 10 is completed, the overall average density is still less than the density of the surrounding water environment, so the sampling bottle 10 after sampling is still floating on the liquid surface. The automatic sampling volume of the sampling bottle 10 is equal to the discharge volume of the sampling bottle 10. According to the sampling volume requirement of the water sample, the average density of different areas of the sampling bottle 10 is designed so that the automatic sampling volume of the sampling bottle 10 meets the requirement.

[0079] Optionally, the overall average density of the sampling bottle 10 before sampling is equal to the density of the liquid sample. After the sampling bottle 10 is placed at the sampling point, the water inlet pipe 103 is located in the area of ​​the sampling bottle 10 with the highest average density. The water inlet pipe 103 first sinks below the liquid surface, so that the water sample is collected from the water inlet pipe 103 into the bottle body 102, and the gas in the bottle body 102 is discharged to the outside through the gas outlet pipe 106. When the bottle body 102 is full of water samples, sampling stops automatically, and the sampling bottle 10 is suspended below the liquid surface after collection.

[0080] Optionally, the overall average density of the sampling bottle 10 before sampling is greater than the density of the water sample, and the sampling bottle 10 sinks below the liquid surface after sampling. The automatic sampling volume of the sampling bottle 10 is equal to the total volume of the sampling bottle 10. According to the sampling volume requirement of the water sample, the overall average density of the sampling bottle 10 and the total volume of the sampling bottle 10 are designed so that the automatic sampling volume of the sampling bottle 10 meets the requirement.

[0081] In addition, as another option, a vacuum chamber can be set in the bottle body 102, and the pressure in the vacuum chamber is lower than the atmospheric pressure. When the control module 11 controls the water inlet valve 104 to open, the pressure difference between the vacuum chamber and the atmospheric pressure is used to automatically and quantitatively pressurize the water sample into the vacuum chamber of the sampling bottle 10. In addition, the pressure in the vacuum chamber can be adjusted in advance according to the required injection volume. After the sampling bottle 10 is placed in the water, the water inlet pipeline 103 is located below the water surface. The control module 11 opens the water inlet valve 104, and the pressure difference between the vacuum chamber and the atmospheric pressure is used to automatically pressurize the water sample into the vacuum chamber of the sampling bottle 10, until the water sample in the vacuum chamber reaches the required injection volume, and the injection is automatically stopped.

[0082] It can be understood that in the above two options, the control module 11 only needs to control the water inlet valve 104 to open and start automatic sampling, and no additional control is required to stop the sampling. The sampling bottle 10 automatically stops the sampling based on its own posture after sampling.

[0083] It can be understood that the bottle cap 101 and the bottle body 102 are designed separately, and an anti-counterfeiting detection device 105 for detecting whether the bottle cap 101 is twisted is arranged between the bottle cap 101 and the bottle body 102, and the anti-counterfeiting detection device 105 is electrically connected to the control module 11, and the control module 11 is also used to record the twisting event or generate an alarm message to transmit to the remote management platform when the anti-counterfeiting detection device 105 detects that the bottle cap 101 is twisted, so as to remind the staff that the water sample may be tampered with and give up using the water sample for detection, thereby playing the role of water sample anti-counterfeiting. In addition, when the environmental perception sensor 12 monitors abnormal water quality, liquid level changes, temperature changes, etc., the control module 11 can record abnormal events or generate alarm information to transmit to the remote management platform, thereby playing a monitoring reminder role.

[0084] Wherein, the anti-counterfeiting detection device 105 includes at least one of a piezoelectric sensor, an electromagnetic sensor, a contact switch and a probe. When a piezoelectric sensor is used, the piezoelectric sensor is arranged between the bottle cap 101 and the bottle body 102. When the bottle cap 101 is twisted, the piezoelectric sensor can detect the pressure change and feedback to the control module 11. The control module 11 can record the twisting event or generate an alarm message to transmit to the remote management platform to remind the staff that the water sample may be tampered with. When an electromagnetic sensor is used, the electromagnetic sensor is arranged between the bottle cap 101 and the bottle body 102. When the bottle cap 101 is twisted, it will cause a magnetic field change. The electromagnetic sensor will generate a feedback electrical signal and transmit it to the control module 11. The control module 11 can record the twisting event or generate an alarm message to transmit to the remote management platform. When a contact switch is used, one contact is set on the bottle cap 101, and the other contact is set on the bottle body 102. When the bottle cap 101 is tightened, the two contacts are just in contact, and the circuit is turned on. When the bottle cap 101 is twisted, the two contacts are staggered, and the circuit is disconnected. The control module 11 can monitor that the circuit is in a disconnected state, and it can be determined that the bottle cap 101 is twisted. The control module 11 records the twisting event or generates an alarm message and transmits it to the remote management platform. When a probe is used, one probe is set on the bottle cap 101, and the other probe is set on the bottle body 102. When the bottle cap 101 is tightened, the two probes are just in contact, and the circuit is turned on. When the bottle cap 101 is twisted, the two probes are staggered, and the circuit is disconnected. The control module 11 can monitor that the circuit is in a disconnected state, and it can be determined that the bottle cap 101 is twisted. The control module 11 records the twisting event or generates an alarm message and transmits it to the remote management platform. In addition, as an option, the sampling bottle 10 is also provided with an anti-counterfeiting label, and each sampling bottle 10 corresponds to a unique anti-counterfeiting label. When the water sample is taken back to the laboratory, the label information is obtained by scanning the anti-counterfeiting label, and compared with the pre-stored label information to verify the authenticity of the sampling bottle 10, so as to prevent the entire sampling bottle 10 from being replaced during transportation, further improving the anti-counterfeiting performance of the water sample. The anti-counterfeiting label can be at least one of a QR code, a barcode, and an RFID.

[0085] As another option, the bottle cap 101 is provided with a probe extending into the bottle body 102 and used to detect the conductivity of the water sample, and the probe is electrically connected to the control module 11. The control module 11 is also used to record as a marking event or generate an alarm message to transmit to the remote management platform when the probe detects that the conductivity of the water sample has changed, thereby improving the anti-counterfeiting performance of the water sample. For example, after the bottle cap 101 is unscrewed, the detection result of the probe will be reset to zero, so that the control module 11 can determine that the bottle cap 101 is unscrewed and the water sample may be tampered with. The control module 11 is recorded as a marking event or generates an alarm message to transmit to the remote management platform to remind the detection personnel that the bottle cap 101 has been opened. Alternatively, when the bottle body 102 is artificially destroyed without unscrewing the bottle cap 101 to replace the water sample, the probe can detect that the conductivity of the water sample before and after has changed, and the control module 11 is recorded as a marking event or generates an alarm message to transmit to the remote management platform to remind the detection personnel that the water sample has been tampered with. In addition, in other embodiments of the present invention, the control module 11 can also obtain the liquid level status in the bottle body 102 according to the detection result of the probe. For example, the insertion position of the probe in the bottle body 102 is set according to the preset liquid level position. For example, when the position of the bottom of the probe in the bottle body 102 corresponds to a liquid level of 50 ml, when the water sample reaches a liquid level of 50 ml in the bottle body 102, the probe has detection data, so that the control module 11 can determine that the current liquid level is 50 ml; or, the bottom of the probe is located at a position flush with the top of the bottle body 102, and the probe can only have detection data when the bottle body 102 is filled with water samples.

[0086] Preferably, the sampling bottle 10 further includes a pressure sensor for detecting the pressure in the bottle body 102 or a liquid level detection sensor for detecting the liquid level in the bottle body 102, and the control module 11 is further used to control the sampling state according to the detection result of the pressure sensor or the liquid level detection sensor to achieve quantitative sampling. The pressure detection result of the pressure sensor and the liquid level detection result of the liquid level detection sensor can be converted into a sampling volume accordingly. The pressure sensor or the liquid level detection sensor is used to monitor the sampling volume in the sampling bottle 10 in real time and transmit the detection result to the control module 11. The control module 11 controls the sampling state according to the detection result, thereby achieving quantitative sampling. The liquid level detection sensor includes at least one of a liquid level sensor and a proximity sensor.

[0087] Preferably, the sampling bottle 10 is also equipped with a positioning module 14 electrically connected to the control module 11, and the control module 11 is also used to obtain the location information of the sampling bottle 10 through the positioning module 14. Among them, the positioning module 14 can be any one of a GPS positioning module, a Beidou positioning module, and a Galileo positioning module. The position of the sampling bottle 10 can be obtained in real time through the positioning module 14, and the real-time position can be associated with the monitoring data and stored or transmitted to the remote management platform together, which improves the authenticity of the sampling, and can also facilitate the recovery of the sampling bottle 10. In the subsequent water sample transportation process, the water sample can also be positioned and supervised throughout the process to prevent the water sample from being tampered with during transportation, further improving the anti-counterfeiting performance of the water sample.

[0088] Preferably, the sampling bottle 10 is also equipped with a gyroscope sensor 15 which is electrically connected to the control module 11 and is used to detect the posture of the sampling bottle 10. The control module 11 is also used to record posture abnormality events or generate alarm information and transmit it to the remote management platform when the gyroscope sensor 15 detects that the current posture of the sampling bottle 10 does not conform to a preset posture range. The control module 11 has a preset posture range for the sampling bottle 10 when it is put into the water environment. The posture of the sampling bottle 10 can ensure smooth sampling only when it is within the preset posture range. The current posture of the sampling bottle 10 is detected by the gyroscope sensor 15 and the detection result is transmitted to the control module 11. Once the control module 11 compares and finds that the current posture of the sampling bottle 10 does not meet the preset posture range, it means that the current posture of the sampling bottle 10 does not meet the requirements and may not be able to be sampled normally. For example, the water inlet pipeline 103 is above the liquid surface, and the air outlet pipeline 106 is below the liquid surface. The control module 11 generates an alarm message and transmits it to the remote management platform through the wireless communication module 16, so as to promptly remind the staff to manually adjust the posture of the sampling bottle 10, or the control module 11 records the abnormal posture event to remind the staff to inspect the structure of the sampling bottle 10.

[0089] Preferably, a preservative is pre-installed in the bottle 102 to prevent the collected water sample from deteriorating and affecting subsequent detection.

[0090] In addition, the smart sampling bottle also includes a power module 17 for supplying power to each functional module and sensor. Preferably, it also includes a power supply detector electrically connected to the power module 17 and the control module 11, which can detect the power of the power module 17 in real time. When it is detected that the remaining power of the power module 17 is insufficient, it is fed back to the control module 11, and the control module 11 sends an alarm message to the remote management platform to remind the staff to charge the smart sampling bottle or replace the power module 17 in time. It can be understood that this embodiment can reliably and comprehensively realize the comprehensive and automatic monitoring of the effectiveness of the sample from the completion of sampling to the delivery test, and timely judge whether the sample is illegally replaced before delivery and testing, or whether the sample fails due to reasons such as storage time and storage temperature, so as to ensure the effectiveness, representativeness, timeliness and traceability of the sample, as well as the reliability of the monitoring data, avoid the hidden dangers of sample fraud or failure due to human intervention, thereby ensuring the accuracy and reliability of the final test results of the sample, and providing scientific and accurate monitoring data for environmental monitoring and protection.

[0091] In a preferred embodiment of the present invention, the real-time validity detection information is stored in an intelligent sampling bottle, and the intelligent sampling bottle is provided with a storage module. When delivering samples, the validity of the samples in the intelligent sampling bottle is compared by reading the real-time validity detection information stored in the intelligent sampling bottle and the preset sample validity judgment conditions, and finally the validity of the samples is judged according to the comparison results.

[0092] In this embodiment, the real-time detection information of validity obtained by the smart sampling bottle is stored in the smart sampling bottle. When the smart sampling bottle is delivered to the sample receiving place, the real-time detection information of validity stored in the smart sampling bottle is read first, and then the samples in the smart sampling bottle are compared for validity based on the read real-time detection information of validity and the preset sample validity judgment conditions. Finally, the validity of the samples is judged based on the comparison results. This embodiment can give full play to the data storage function of the smart sampling bottle and reduce the dependence on network communication, especially in some locations with poor communication signals, such as remote areas or sealed spaces with poor signals, so as to avoid the subsequent judgment of the validity of the samples due to data loss when communication abnormalities occur.

[0093] In a preferred embodiment of the present invention, the real-time validity detection information is transmitted to a management platform via wireless communication. The management platform performs a validity comparison on the samples in the smart sampling bottle based on the received real-time validity detection information and preset sample validity judgment conditions, and finally determines the validity of the samples based on the comparison results.

[0094] In this embodiment, during the transportation of samples, the smart sampling bottle will transmit the acquired real-time detection information of validity to the management platform via wireless communication. The management platform will promptly compare the validity of the samples in the smart sampling bottle according to the received real-time detection information of validity and the preset sample validity judgment conditions, and finally judge the validity of the samples according to the comparison results. Since the real-time validity detection information obtained by the smart sampling bottle of this embodiment will be sent to the management platform in a timely manner via wireless communication, the management platform can timely and dynamically judge the validity of the sample based on the received real-time validity detection information and the preset sample validity judgment conditions. That is to say, during the entire transportation process of the smart sampling bottle, the management platform can timely judge the current validity of the sample based on the received real-time validity detection information. After all, the validity of the sample is a dynamic process. For example, when it is judged that the sample is valid at time A, it may be invalid at time B. The management platform of this embodiment can timely judge the current validity of the sample when the real-time validity detection information changes, and then can identify the time, place, and reason for the invalidity of the sample based on the time, place, and other parameters when the real-time validity detection information changes, so as to facilitate a comprehensive and timely grasp of the sample validity change process, and provide necessary reference for how to ensure the validity of the sample during transportation in the future.

[0095] like Figure 2 As shown, in a preferred embodiment of the present invention, the effectiveness comparison of the samples in the smart sampling bottle is performed according to the effectiveness real-time detection information and the preset sample effectiveness judgment conditions, and finally the effectiveness of the samples is judged according to the comparison results, which specifically includes the steps of:

[0096] S201, obtaining a sample storage time, where the sample storage time is the difference between the sample delivery time and the sampling time;

[0097] S202: If the sample storage time is longer than the preset sample storage period, the current sample is determined to be an expired sample.

[0098] In some scenarios, for some samples, the storage time of the samples from the completion of sampling to the delivery for testing is an important factor affecting the validity of the samples. If the storage time is too long, the samples will become invalid. Therefore, the storage time is one of the important indicators for judging the validity of the samples. In this embodiment, the difference between the sample delivery time and the sampling time is used as the storage time of the current sample, and the validity of the sample is judged based on the comparison result of the storage time and the sample storage period in the preset sample validity judgment condition. If the storage time is longer than the sample storage period, the sample is judged to be an invalid sample.

[0099] like Figure 3As shown, in a preferred embodiment of the present invention, the effectiveness comparison of the samples in the smart sampling bottle is performed according to the effectiveness real-time detection information and the preset sample effectiveness judgment conditions, and finally the effectiveness of the samples is judged according to the comparison results, which specifically includes the steps of:

[0100] S211, obtaining the sample storage temperature recorded in real time during the sample transportation process;

[0101] S212, record the sample temperature change in real time, and obtain the duration that the sample storage temperature exceeds the allowable range;

[0102] S213: If the storage temperature of the sample exceeds the allowable range for a period of time exceeding a set threshold,

[0103] or,

[0104] When the proportion of the duration in the total duration of the transportation link is greater than the set threshold, the current sample is determined to be an invalid sample.

[0105] In some scenarios, the storage temperature of the sample from the completion of sampling to the delivery of the test is an important factor affecting the validity of the sample. If the storage temperature exceeds the allowable range for too long, the sample will become invalid. Therefore, the duration of the storage temperature exceeding the allowable range is one of the important indicators for judging the validity of the sample. This embodiment obtains the storage temperature during the sample transportation process and the duration of the sample storage temperature exceeding the allowable range, and judges the validity of the sample based on the comparison result of the duration of the sample storage temperature exceeding the allowable range and the threshold of the duration of the storage temperature exceeding the allowable range in the preset sample validity judgment condition. If the duration of the sample storage temperature exceeding the allowable range is greater than the threshold, the sample is judged to be an invalid sample. When the storage temperature exceeds the standard, the sample will not all become invalid immediately. That is to say, even if the storage temperature exceeds the standard for a short time, it will not affect the overall validity of the sample. Therefore, this embodiment takes the storage temperature as an indicator for judging the validity of the sample while comprehensively considering the influence of the duration of the temperature exceeding the standard. Only when the temperature exceeds the standard for a duration greater than the set threshold is the sample judged invalid to avoid misjudgment.

[0106] like Figure 4 As shown, in a preferred embodiment of the present invention, the effectiveness comparison of the samples in the smart sampling bottle is performed according to the effectiveness real-time detection information and the preset sample effectiveness judgment conditions, and finally the effectiveness of the samples is judged according to the comparison results, which specifically includes the steps of:

[0107] S221. After the sampling is completed and before the sampling is delivered for testing, detect whether the cover of the smart sampling bottle has been disassembled, and obtain a corresponding detection signal;

[0108] S222. Determine the authenticity of the corresponding sampling according to the corresponding detection signal: if there is disassembly, it is prompted that the cover of the corresponding smart sampling bottle is illegally opened, and the current sample is determined to be an invalid sample; otherwise, it is prompted that the corresponding smart sampling bottle is in normal working condition.

[0109] In some scenarios, illegal replacement of samples may occur from the completion of sampling to the delivery of testing, that is, the real sample is replaced with a forged sample, which will cause the subsequent test results to fail to truly reflect the actual data of the original sample. Therefore, ensuring the authenticity of the sample is one of the important indicators for judging the validity of the sample. In view of the above problem, this embodiment mainly focuses on the smart sampling bottle with a detachable cup body and cover body, and detects whether the cover body of the smart sampling bottle is disassembled after the completion of sampling and before delivery for testing as an important reference to determine whether the smart sampling bottle has been opened. If it has been opened, there is a possibility of illegal replacement of the sample in the smart sampling bottle. At this time, the sample is judged to be an invalid sample, which prevents someone from illegally replacing the sample in the bottle by opening the cover body of the smart sampling bottle, thereby ensuring the authenticity of the sample.

[0110] Furthermore, if Figure 5 As shown, in a preferred embodiment of the present invention, the step of determining the authenticity of the corresponding sample according to the corresponding detection signal specifically includes the following steps:

[0111] S301, detecting the pressure value between the cover body and the cup body in real time, and obtaining a corresponding detection signal;

[0112] S302. If the detected pressure value between the cover and the cup is lower than the set threshold, it is prompted that the cover of the corresponding smart sampling bottle is illegally opened, and the current sample is determined to be an invalid sample; otherwise, it is prompted that the corresponding smart sampling bottle is in a normal working state.

[0113] For the cover body and the cup body connected by threads, after normal tightening, there will be a certain pressure between the cover body and the cup body. If the cover body and the cup body are loose, the pressure between the cover body and the cup body will change. Based on the above principle, this embodiment can determine whether the cover body of the smart sampling bottle has been illegally opened by checking the relationship between the pressure value between the cover body and the cup body and the set threshold. If the pressure value is lower than the set threshold, it means that the cover body of the smart sampling bottle has been illegally opened, and the sample is judged to be an invalid sample. Otherwise, it means that the smart sampling bottle is in normal working state, and the sample is judged to be a valid sample. The pressure check can be realized by a pressure sensor set between the cup cover and the cup body and outputting a corresponding detection signal.

[0114] Furthermore, if Figure 6 As shown, in a preferred embodiment of the present invention, the step of determining the authenticity of the corresponding sample according to the corresponding detection signal specifically includes the following steps:

[0115] S401, detecting the relative displacement between the cover body and the cup body in real time, and obtaining a corresponding detection signal;

[0116] S402. If there is a relative displacement between the cover and the cup, it is prompted that the cover of the corresponding smart sampling bottle is illegally opened, and the current sample is determined to be an invalid sample; otherwise, it is prompted that the corresponding smart sampling bottle is in a normal working state.

[0117] For the cover body and the cup body connected by threads, after normal tightening, if the cover body and the cup body are loose, a certain relative displacement will occur between the cover body and the cup body. Based on the above principle, this embodiment can determine whether the cover body of the smart sampling bottle has been illegally opened by checking whether there is a relative displacement between the cover body and the cup body. If there is a relative displacement, it means that the cover body of the smart sampling bottle has been illegally opened. At this time, the sample is judged to be an invalid sample. Otherwise, it means that the smart sampling bottle is in a normal working state. At this time, the sample is judged to be a valid sample. Specifically, the relative displacement can be checked by an electromagnetic sensor, a contact switch or two conductive probes arranged between the cup cover and the cup body, and the corresponding detection signal can be output.

[0118] like Figure 7 As shown, in a preferred embodiment of the present invention, before determining the authenticity of the corresponding sample according to the corresponding detection signal, the step of:

[0119] S501, detecting the number of rotations of the cover body relative to the cup body, and outputting a corresponding detection signal;

[0120] S502. If the detected number of rotations is lower than a set threshold, it indicates that the corresponding smart sampling bottle is in a normal working state; otherwise, it indicates that the cover of the corresponding smart sampling bottle is not tightly closed.

[0121] This embodiment automatically determines whether the cover of the smart sampling bottle is tightly closed by detecting whether the number of rotations of the cover relative to the cup body reaches a set threshold, thereby preventing sample leakage from the smart sampling bottle during transportation. The detection means include using a magnetic induction sensor, etc. At the same time, the specific prompt method can be provided by setting a warning light or an audio alarm on the smart sampling bottle. In addition, the relevant alarm information can be transmitted to the management platform through wireless communication after being recorded, or stored locally in the smart sampling bottle.

[0122] In a preferred embodiment of the present invention, the effectiveness comparison of the samples in the smart sampling bottle is performed according to the effectiveness real-time detection information and the preset sample effectiveness judgment conditions, and finally the effectiveness of the samples is judged according to the comparison results, which further includes the steps of:

[0123] The anti-counterfeiting label set on the smart sampling bottle is read to perform anti-counterfeiting identification on the smart sampling bottle to prevent the smart sampling bottle from being illegally replaced. The anti-counterfeiting label includes an RFID chip, an NFC chip or an anti-counterfeiting QR code. In this embodiment, the anti-counterfeiting identification of the smart sampling bottle can be achieved by reading the anti-counterfeiting label set on the smart sampling bottle to prevent the smart sampling bottle from being illegally replaced.

[0124] In a preferred embodiment of the present invention, the real-time validity detection information includes the identity information of the person submitting the sample. When monitoring the validity of the sample in the smart sampling bottle, if it is detected that the identity information of the person submitting the sample is inconsistent with the pre-stored identity information of the person submitting the sample, the current sample is determined to be an invalid sample. The identity information of the person submitting the sample is obtained by photographing with a camera, or by photographing with an APP on the mobile phone of the person submitting the sample.

[0125] In some cases where the validity test of samples is more stringent, in order to ensure the validity of samples, in addition to the need to adopt various validity test methods such as those in the aforementioned embodiments, it is also necessary to identify the identity information of the person submitting the sample to ensure the legitimacy of the identity of the person submitting the sample. Only when the identity of the person submitting the sample also meets the relevant requirements can the validity of the sample be determined. To this end, this embodiment also includes the identity recognition information of the person submitting the sample in the obtained real-time validity detection information, such as obtaining the facial image information of the person submitting the sample through a camera or through the mobile phone APP of the person submitting the sample, and the facial image information is transmitted to the management platform, and the management platform compares the facial image information with the pre-stored personnel identity recognition information. The comparison method can adopt face recognition technology, etc. Finally, the identity of the current person submitting the sample is judged by the identification result whether it meets the relevant requirements. If not, the sample is determined to be an invalid sample. This embodiment combines the identity information of the person submitting the sample to conduct a comprehensive validity test on the sample, further improving the reliability, comprehensiveness and traceability of sample validity monitoring.

[0126] In a preferred embodiment of the present invention, during the sampling and transportation of samples, a panoramic camera is provided to monitor the sampling process throughout the process. The panoramic camera can monitor the entire process without blind spots to ensure the validity of the samples. The image data captured by the panoramic camera can be transmitted to the management platform via wireless communication, or stored locally in the smart sampling bottle.

[0127] In a preferred embodiment of the present invention, when obtaining real-time validity detection information, the real-time validity detection information also includes posture information and vibration signals obtained by the smart sampling bottle during the entire transportation process. The vibration signal is collected by a gyroscope or an acceleration sensor arranged on the smart sampling bottle. The posture information is collected by the gyroscope. The vibration signal includes vibration amplitude and vibration frequency. For a normally transported smart sampling bottle, its posture should be basically unchanged, such as placed vertically or tilted at a fixed angle. If the gyroscope detects that the posture information of the smart sampling bottle during transportation is inconsistent with the preset posture information, it is judged that there is an abnormality in the transportation of the smart sampling bottle and there is a possibility of human intervention, and the sample is determined to be an invalid sample. Similarly, for a normally transported smart sampling bottle, its vibration amplitude and vibration frequency generally have a reasonable value range. When the present embodiment determines the validity of the sample based on the vibration signal, if the vibration amplitude and vibration frequency in the obtained vibration signal exceed the preset reasonable value range, it is determined that the smart sampling bottle has abnormal vibration during transportation. The abnormal vibration may involve violent shaking of the smart sampling bottle, physical damage to the smart sampling bottle by external force, and other related behaviors. The sample is ultimately determined to be an invalid sample, thereby preventing someone from tampering with the sample by first damaging the smart sampling bottle (such as drilling a hole), then replacing the sample, and finally repairing the damaged part, thereby ensuring the validity of the sample.

[0128] In a preferred embodiment of the present invention, when obtaining the real-time validity detection information, the real-time validity detection information also includes the trajectory and position information of the sample acquired by the positioning module 14 during the whole process of transportation of the smart sampling bottle. For the normally transported smart sampling bottle, its trajectory and position information should be basically consistent with the preset trajectory and position data. If the deviation between the trajectory and position information collected during the transportation of the sample and the preset trajectory and position data exceeds the threshold, it is judged that there is an abnormality in the transportation of the smart sampling bottle and there is a possibility of human intervention, and the sample is determined to be an invalid sample.

[0129] In a preferred embodiment of the present invention, the material of the smart sampling bottle is set to tempered glass. Since tensile stress is formed inside the tempered glass after processing, the smart sampling bottle has good impact resistance. However, once the tempered glass is damaged, such as by cutting, grinding, drilling or other processing or damage, it will cause irreversible shattering due to the destruction of its internal stress balance. This embodiment utilizes the above-mentioned characteristics of tempered glass. As long as someone damages the smart sampling bottle, the smart sampling bottle will have a large number of irreversible cracks, so that the sample is judged as an invalid sample, thereby preventing someone from tampering with the sample by first damaging the smart sampling bottle (such as drilling), then replacing the sample, and finally repairing the damaged part.

[0130] In a preferred embodiment of the present invention, the smart sampling bottle is provided with a sealed interlayer, and the interlayer is preset to a negative pressure state. Once the smart sampling bottle is damaged, such as by cutting, grinding, drilling or other processing or damage, the sealing of the interlayer will be destroyed, thereby causing the pressure in the interlayer to change. This embodiment utilizes the above-mentioned sealed interlayer with negative pressure inside. When someone damages the smart sampling bottle, the pressure value in the interlayer changes. At this time, the pressure sensor arranged in the sealed interlayer will detect the pressure value in the interlayer. Then, when the validity of the sample is judged according to the pressure value, if the pressure value is greater than the set threshold value, it means that the smart sampling bottle is damaged, and the sample is judged as an invalid sample.

[0131] In a preferred embodiment of the present invention, the effectiveness comparison of the samples in the smart sampling bottle is performed according to the effectiveness real-time detection information and the preset sample effectiveness judgment conditions, and finally the effectiveness of the samples is judged according to the comparison results, which further includes the steps of:

[0132] S601, obtaining the detection result of the conductivity probe in the smart sampling bottle in real time;

[0133] S602: If the conductivity probe detects that the conductivity or liquid level of the sample in the smart sampling bottle changes, the current sample is determined to be a failed sample.

[0134] This embodiment determines the validity of the sample by detecting changes in conductivity or liquid level status. For example, when the bottle cap 101 is unscrewed, the detection result of the conductivity probe will be reset to zero, so that the control module 11 can determine that the bottle cap 101 is unscrewed and the water sample may be tampered with. The control module 11 records it as a marked event or generates an alarm message to transmit to the management platform to remind the inspection personnel that the bottle cap 101 has been opened. Alternatively, when the bottle body 102 is manually damaged without unscrewing the bottle cap 101 to replace the water sample, the conductivity probe can detect that the conductivity of the water sample before and after has changed. The control module 11 records it as a marked event or generates an alarm message to transmit to the management platform to remind the inspection personnel that the water sample has been tampered with. In addition, in other embodiments of the present invention, the control module 11 can also obtain the liquid level status in the bottle body 102 according to the detection result of the conductivity probe. For example, the insertion position of the conductivity probe in the bottle body 102 is set according to the preset liquid level position. For example, when the position of the bottom of the conductivity probe in the bottle body 102 corresponds to a liquid level of 50 ml, when the water sample reaches a liquid level of 50 ml in the bottle body 102, the conductivity probe has detection data, so that the control module 11 can determine that the current liquid level is 50 ml; or, the bottom of the conductivity probe is located at a position flush with the top of the bottle body 102, and the conductivity probe can only have detection data when the bottle body 102 is filled with water sample.

[0135] In a preferred embodiment of the present invention, the water inlet valve 104 and the air outlet valve 107 of the smart sampling bottle are preset with authority control and have record information throughout the process. If an illegal authority operation record appears in the record information, the current sample is determined to be an invalid sample.

[0136] In a preferred embodiment of the present invention, when obtaining the effectiveness real-time detection information, the effectiveness real-time detection information also includes the sealing inspection information of the valve and bottle cap obtained during the transportation of the smart sampling bottle. The specific acquisition method can adopt water immersion method, dry air method, tracer gas method, etc., which can be operated manually or by a related sealing detector. If the sealing of the valve and bottle cap is lower than the setting, the current sample is determined to be a failed sample.

[0137] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
