Description
Technical Field
The invention relates to a hydrologic monitoring system, in particular to a groundwater monitoring system. The system can be matched with a remote control center to realize data acquisition of unattended groundwater monitoring points in multiple areas, thereby realizing unattended groundwater monitoring.
Background
The underground water monitoring is that an underground water monitoring management department monitors data such as underground water level, water quality and the like in a district so as to grasp dynamic change conditions in time and protect underground water for a long time. For water level monitoring, the current common water level sensor is mature, and the fixed water level sensor penetrating into the underground water layer is arranged through the fixed monitoring points, so that the timed water level data acquisition of the underground water can be realized. Meanwhile, in the existing underground water monitoring system, the water level information of underground water can be sent to a remote control center in real time through a mobile communication network. However, for water quality monitoring, the detection content generally includes a series of detection of water temperature, salinity, turbidity, dissolved chlorine, and microorganism content. As the detection, the sensor with maturity can be adopted at present, for example, the water temperature can be realized by a common temperature sensor, and the electrochemical sensor can be a pH glass electrode, a solid ion selective electrode (measurable O) 2 、S 2- 、F - 、Cl - 、Br - Etc.), sulfide glass electrode (measurable Fe 3+ 、Ca2 + Plasma), ion exchanger liquid film and PVC membrane electrode (NO measurable) 3 - 、NH 4 + Etc.), neutral carrier electrode (measurable K + Etc.), wire coated electrode (measurable Pb, au etc.), gas sensitive electrode (measurable NH) 4 + Etc.), coated piezoelectric crystal sensor (measurable Cu 2+ Etc.) and an enzyme and bacteria biosensor (e.g., a microbial sensor of the biosciences instruments company of japan). Conventional water quality monitoring, the sensors are integrally assembled and integrated together to form a throw-In type detection mechanism, and the In-Situ type water quality detection mechanism is represented by the brand. When water quality monitoring is needed, relevant staff carries a water quality detector to reach an appointed monitoring point, and the water quality detector is put into an underground water layer from a ground reserved observation port to detect. Because the cost of various water quality sensors is high, the water quality detector put into an underground water layer is not suitable for long-term retention as an unattended monitoring station. And for electrochemical purposesThe chemical sensor and the microbial sensor have practical design life, and the life of the sensor can be greatly shortened after the chemical sensor and the microbial sensor are soaked in underground water for a long time. However, the current water quality monitoring is seriously dependent on the participation of staff, and is also a great waste of labor cost to some extent.

Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present disclosure more apparent, the technical solutions of the embodiments of the present disclosure will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present disclosure. It will be apparent that the described embodiments are some, but not all, of the embodiments of the present disclosure. All other embodiments, which can be made by one of ordinary skill in the art without the need for inventive faculty, are within the scope of the present disclosure, based on the described embodiments of the present disclosure.
In order to keep the following description of the embodiments of the present disclosure clear and concise, the present disclosure omits detailed description of known functions and known components.
As shown in fig. 1, an embodiment of the present invention provides a groundwater monitoring system, the system including:
a remote control center 10 configured to establish communication connection with a plurality of unmanned monitoring stations 40 and collect groundwater monitoring data collected by the unmanned monitoring stations 40 deployed in different areas; in this embodiment, a plurality of unmanned monitoring stations 40 establish connections with the remote control center 10 through the mobile communication network 40 via the gateway 20.
Fig. 2 illustrates a specific structure of the unmanned monitoring station 40, as shown in fig. 2 and 5, wherein the unmanned monitoring station 40 includes a riser 41 penetrating into the groundwater layer 300 and a control box 42 fixed on the riser 41, and the riser 41 is provided with a water level sensor 200 at one end of the groundwater layer 300. In some embodiments, it is contemplated that the riser 41 is in a field operating environment, and thus, as shown in FIG. 2, it is also contemplated that the support mechanism 44 may be added for support. Specifically, the supporting mechanism 44 may include a sleeve 441 sleeved outside the riser 41, and the outer edges of the sleeve 441 are respectively connected to a plurality of supporting rods 442, where the supporting rods 442 may be directly supported or partially buried in the stratum, or may be anchored to the ground by anchor bolts 443. For the water level sensor 200, a general ZigBee-based level sensor may be used in the present invention. With further reference to fig. 2, the other end of the riser 41 is provided with a photovoltaic power generation unit 43 for supplying power to the control box 42, and since the unmanned monitoring station 40 is disposed in an outdoor environment, power supply to the electrical part in the control box 42 can be realized through the photovoltaic power generation unit 43, and in order to improve the working stability, it is also possible to additionally add a storage battery (not shown in the figure) in the control box 42; in addition, as shown in fig. 3 to 5, the control box 42 is provided with a microcontroller 429, a communication unit 425, a water quality detecting mechanism (not labeled in the drawings), and a dc pump 400, wherein the communication unit 425 is configured to establish a communication connection with the remote control center 10, and in consideration of stability of the communication connection, the communication unit 425 may preferably further increase an antenna 4251 electrically connected thereto. In the present invention, the communication unit 425 may be exemplified by a WIFI module, a bluetooth module, or a mobile communication module, preferably a mobile communication module, such as a 2G, 3G, 4G, or 5G module. The dc pump 400 is controlled by the microcontroller 429 to pump water to the water quality monitoring mechanism, which includes at least a temperature sensor 428 for detecting water temperature information of groundwater, an electrochemical sensor 424 for detecting chemical elements in the groundwater, and a microorganism sensor 423 for detecting microorganisms contained in the groundwater. It should be noted that, in the present invention, the water level sensor 200, the temperature sensor 428, the electrochemical sensor 424 and the microbial sensor 423 may be conventional sensors within the knowledge range of those skilled in the art, for example, the electrochemical sensor is selected from the group consisting of pH glass electrode, solid ion selective electrode, sulfide glass electrode, ion exchanger liquid film and PVC film electrode, neutral carrier electrode, wire-coated electrode, gas-sensitive electrode and coated piezoelectric crystal sensor. The microbial sensor 423 may be, for example, a microbial sensor available from Bionics instruments, japan.
For the specific arrangement of the above-mentioned sensors, an implementation manner is shown in fig. 3 and fig. 4, and as shown in fig. 3 and fig. 4, preferably, the water quality detection mechanism includes a bottom shell 421 and a top cover 426 that is fastened to the bottom shell 421, and in some embodiments, one or more sealing rings 100 may be disposed between the top cover 426 and the bottom shell 421 to improve the sealing effect. The bottom case 421 is configured to form a receiving cavity (not labeled in the figure) for receiving a detection sample, and is provided with a water inlet pipe 4211 connected to the dc pump 400, and a water outlet pipe 4212 for discharging the detection sample in the receiving cavity; the temperature sensor 428, the electrochemical sensor 424, the microbial sensor 423, and the communication unit 425 are respectively disposed on the top cover 426. In the present invention, the microcontroller 429 may be triggered by a preset condition (e.g., a period of time such as day, week or month is taken as a preset condition), and the control command controls the dc pump 400 to draw the detection sample from the groundwater layer into the accommodating cavity, and the temperature sensor 428, the electrochemical sensor 424, and the microbial sensor 423 further detect the water temperature, chemical elements, and microbial indicators of the detection sample in the accommodating cavity. The detected data is in turn transmitted to the remote control center 10 through the communication unit 425. Meanwhile, the preset condition may also be a control instruction issued by the remote control center 10.
In particular, in order to improve the detection accuracy when actually monitoring the water temperature, it is preferable that, as shown in fig. 3, a heat conducting mechanism 422 is disposed in the accommodating cavity near the inner wall, and the heat conducting mechanism 422 is at least partially abutted against the temperature sensor 428 on the top cover 426. In this way, the temperature sensor 428 does not need to directly contact the detection sample, so that inaccurate detection results caused by incomplete contact of the sensor with water are avoided, and meanwhile, the temperature sensor 428 does not need to directly contact the water, so that the service life of the sensor can be prolonged. In some embodiments, the heat conducting mechanism 422 may illustratively include a cylindrical heat conducting sleeve 4221 and a spiral heat conducting wire 4222 embedded within the heat conducting sleeve 4221. The heat conductive sleeve 4221 and the heat conductive wire 4222 are made of materials with good heat conduction performance, such as aluminum, copper or silver. In addition, the heat conductive wires 4222 are disposed because, on the one hand, a larger heat conductive area is formed on the heat conductive sleeve 4221, on the other hand, the heat conductive mechanism 422 can be made of different materials and different heat conductive properties, for example, silver has excellent heat conductive properties but has too high cost, so that after the heat conductive wires 4222 are introduced, copper or aluminum with relatively low cost but good heat conductive properties can be used for manufacturing the heat conductive sleeve 4221, and meanwhile, a silver heat conductive wire is embedded on the heat conductive sleeve 4221, so that the scheme can improve the whole heat conductive property of the heat conductive mechanism 422 while simultaneously taking the cost into consideration. It will be understood by those skilled in the art that, in the present embodiment, the heat conducting wire 4222 is spirally embedded in the outer side wall of the heat conducting sleeve 4221, but in practice, a heat conducting ring formed by a plurality of heat conducting wires arranged in a plurality of annular shapes may also implement the present invention.
As a further improvement, in order to avoid the influence of silt when the chemical composition detection is implemented, a cylindrical filter screen 427 may be preferably disposed inside the heat conducting mechanism 422 as shown in fig. 3. The filter 427 is used to filter silt. In this way, relatively more accurate measurements may be achieved by performing chemical and microbiological detection within the filter screen 427. However, in order to avoid mutual interference, it is also conceivable to provide a detection chamber 4242 with a top opening (not labeled in the figure) inside the filter screen 427 in the accommodating chamber, and a detection electrode 4241 is electrically connected to the electrochemical sensor 424, and the detection electrode 4241 extends into the detection chamber 4242 from the opening. The structure can realize mutual isolation of samples for water temperature, chemical component detection and microorganism detection, and has no influence on each other, so that more accurate detection can be realized.
Of course, what has been described above is a preferred embodiment of the present invention, and it should be noted that it will be apparent to those skilled in the art that modifications and adaptations can be made without departing from the principle of the present invention, and these modifications and adaptations are also considered as protecting the scope of the present invention.
