Description

Technical Field

[0001] The present invention relates to the technical field of water quality sampling, and in particular to a water environment intelligent sampling terminal with a monitoring function. Background Art

[0002] At present, water ecological environment monitoring departments conduct sampling and monitoring of water environment quality and sewage discharge, urban and rural drinking water monitoring departments conduct sampling and monitoring of water supply, water conservancy monitoring departments monitor the effectiveness of river pollution control, or relevant departments entrust social testing agencies to conduct sampling and monitoring of related monitoring services. In most cases, manual sampling is used, and a small number of automatic water quality samplers are installed on site to automatically retain samples.

[0003] Manual sampling is suitable for sampling needs with low frequency (such as once a month / week), or needs with high frequency but short sampling distance (such as sampling within the factory). When it is necessary to seize the critical point of the external environmental conditions of the sampling point (such as sampling at low tide and high tide, sampling when the discharge port flow reaches a certain value, sampling when the water level reaches a certain value), if manual sampling is used, there are many disadvantages such as difficulty in capturing the sampling opportunity, difficulty in controlling the sampling quality, and high personnel input.

[0004] Automatic water quality samplers are suitable for sampling needs with higher frequency. They can achieve equal time, equal quantity, time proportion, flow proportion and trigger sampling when external conditions change to critical points. Compared with manual sampling, they have many advantages, but they also have the disadvantage of relatively high requirements for on-site installation and use conditions. For example, they need to be installed on a fixed base on site, sampling integrated pipelines need to be installed, and external AC power is required. Especially for field sampling in the river basin, the automatic water quality sampler cannot be installed in the most suitable position due to the influence of on-site conditions, thus failing to achieve the best sampling and monitoring effect.

[0005] Therefore, there is an urgent need for an intelligent sampling terminal that can automatically identify and perceive the sampling environment, capture changes in relevant parameter indicators of the surrounding water environment, trigger automatic sampling and sample retention functions, capture the best sampling opportunity, and thus collect the most representative water samples. At the same time, by monitoring the water environment at the sampling point and relevant parameters of the water samples entering the sampling terminal, the risk of changing the sample fluid of the water samples during the collection, transportation, and inspection process can be eliminated, thereby ensuring the consistency and authenticity of the water samples during the collection, transportation, and sample delivery process.

DETAILED DESCRIPTION

[0029] The embodiments of the present invention are described in detail below with reference to the accompanying drawings. However, the present invention can be implemented in many different ways as defined and covered below.

[0030] like Figures 1 to 5 As shown, a preferred embodiment of the present invention provides a water environment intelligent sampling terminal with a monitoring function, which includes a sampling bottle 10, on which a control module 11 and a plurality of environment perception sensors 12 are installed, wherein the environment perception 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 perception sensor 12. Among them, the environment perception 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 concentration of dissolved oxygen 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.

[0031] It can be understood that the water environment intelligent sampling terminal with monitoring function 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 within 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.

[0032] 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.

[0033] 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 .

[0034] 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.

[0035] 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.

[0036] 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.

[0037] 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.

[0038] 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.

[0039] 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.

[0040] 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.

[0041] 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.

[0042] 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.

[0043] 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.

[0044] 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.

[0045] 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.

[0046] 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.

[0047] 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.

[0048] 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.

[0049] 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.

[0050] 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.

[0051] 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.

[0052] 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.

[0053] 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.

[0054] 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.

[0055] Preferably, a preservative is pre-installed in the bottle 102 to prevent the collected water sample from deteriorating and affecting subsequent detection.

[0056] In addition, the water environment intelligent sampling terminal with monitoring function also includes a power module 17 for supplying power to various functional modules and sensors. Preferably, it also includes a power supply power 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, and when it is detected that the remaining power of the power module 17 is insufficient, it will be fed back to the control module 11, and the control module 11 will send an alarm message to the remote management platform to remind the staff to charge the water environment intelligent sampling terminal or replace the power module 17 in time.

[0057] Next, several specific application scenarios of the water environment intelligent sampling terminal with supervision function of the present invention are exemplified.

[0058] 1) Enterprise pollution supervision, pollution source tracing and pollution spread:

[0059] At present, in view of the frequent occurrence of sudden environmental pollution accidents and the phenomenon of enterprises secretly discharging, the investigation of pollution accidents and the supervision of enterprise sewage discharge are particularly important. How to efficiently, scientifically and at low cost trace the source of pollution and supervise the discharge of sewage by enterprises has become an urgent problem to be solved by environmental management departments. The existing supervision of pollution source tracing and enterprise sewage discharge mainly relies on environmental monitoring data, and fixed monitoring stations are set up along the banks of rivers and sewage-discharging enterprises. However, due to the high cost and the limited number of fixed monitoring stations, it is impossible to accurately lock the sewage-discharging enterprises. The water environment intelligent sampling terminal with supervision function of the present invention can effectively solve the above problems.

[0060] Among them, for the supervision of enterprise sewage discharge: the water environment intelligent sampling terminal with supervision function of the present invention can be fixedly installed at the sewage outlet of the enterprise, and the water volume at the sewage outlet can be detected in real time. When the flow sensor detects that the discharged sewage reaches a certain flow value / range, the control module 11 controls the water inlet valve 104 to open for sampling, and controls the timer 13 to record the sampling time. The sampling information can also be transmitted to the remote management platform through the wireless communication module 16 to notify the staff to take the water sample in time. In addition, the location can be confirmed through the positioning module 14, as well as the positioning and tracking of the subsequent transportation process.

[0061] Regarding pollution source tracing: the water environment intelligent sampling terminal with supervision function of the present invention can be deployed at any location of the river and the sewage outlet of the enterprise according to the needs. When the environmental perception sensor 12 detects a pollution accident, the remote management platform sends a sampling command at the same time. After receiving the sampling command, the control module 11 controls the water environment intelligent sampling terminal to start sampling. By testing the water samples at the same time, the source of the pollution discharge can be locked and the degree of pollution spread can be accurately judged. In this application scenario, the water environment intelligent sampling terminal can integrate a water pressure sensor to detect the water depth, a piezoelectric sensor for anti-counterfeiting settings, a wireless communication module 16 for signal transmission, a positioning module 14 for position confirmation, and a temperature sensor for temperature detection.

[0062] 2) Tidal sampling:

[0063] Sampling of tidal river sections requires sampling at high tide and low tide. The current tidal sampling method is to send people to wait at high tide sampling points and low tide sampling points to wait for high tide time and low tide time to conduct manual sampling. The sampling requires a lot of manpower and is inefficient. There may even be a situation where the sampling time point is not accurately grasped, resulting in missed sampling. The water environment intelligent sampling terminal with supervision function of the present invention can effectively solve the above problems.

[0064] Specifically, by deploying the water environment intelligent sampling terminal of the present invention at the high tide sampling point and the low tide sampling point, a water pressure sensor is used to monitor the water level change. When the water level change reaches a certain threshold, such as the high tide water level threshold or the low tide water level threshold, the control module 11 controls the sampling bottle 10 to automatically sample. In this application scenario, the water environment intelligent sampling terminal can integrate a water pressure sensor to detect the water level, a piezoelectric sensor for anti-counterfeiting settings, a wireless communication module 16 for signal transmission, a positioning module 14 for position confirmation, a temperature sensor for temperature detection, etc.

[0065] 3) Hydrodynamic sampling:

[0066] The water environment intelligent sampling terminal of the present invention is placed in the river, moved under the power of the water flow, and the position of the sampling bottle 10 is located in real time by the positioning module 14. When it reaches the designated location area, the control module 11 controls the sampling bottle 10 to take samples. When it is necessary to sample multiple points in the river at the same time, it is only necessary to calculate the time of placing multiple water environment intelligent sampling terminals according to the water flow speed, and then the remote management platform sends sampling commands to multiple water environment intelligent sampling terminals at the same time at a certain time point, so as to achieve sampling of multiple designated points at designated times.

[0067] 4) Sampling of water supply network:

[0068] The water environment intelligent sampling terminal of the present invention is placed in a water supply pipe, and sampling can be performed based on flow rate, time, etc. as sampling trigger conditions. For example, when the flow sensor detects that the flow rate in the water supply pipe reaches a certain threshold or range, the control module 11 controls the sampling bottle 10 to automatically sample; or the sampling time is preset in the control module 11, and when the sampling time point is reached, the control module 11 controls the sampling bottle 10 to automatically sample.

[0069] 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.
