Description
Technical field
The present invention relates to a kind of groundwater monitoring equipment, especially relate to a kind of subsoil water automatic monitoring system.
Background technology
Subsoil water refers to composes the water being stored in below ground rock gap, refers to the water in the following saturated aqueous layer of groundwater level in the narrow sense. In national standard " hydrogeology term " (GB/T14157-93), subsoil water refers to and is imbedded in the various forms of gravitational water in below earth's surface. The purposes of subsoil water is enriched, but, in prior art, the detection for indexs such as Groundwater quality detection, WATER LEVEL CHANGES is realized by manpower mostly, and automaticity is low.
Summary of the invention
It is an object of the invention to overcome drawbacks described above, it is provided that a kind of simple in construction, realize convenient subsoil water automatic monitoring system.
To achieve these goals, the present invention is by the following technical solutions:
A kind of subsoil water automatic monitoring system, including the monitoring case being arranged at ground surface, by pipeline, monitoring point subsoil water is evacuated to the pump of described monitoring case, for measuring the water temperature monitor of water temperature in monitoring case, for gathering the water-level instrumentation of monitoring point groundwater level, received described water temperature monitor and the microprocessor of the gathered data of described water-level instrumentation by communication module, receive the backstage monitoring center of the result of calculation of microprocessor output.
Further, described monitoring case is made up of heat-barrier material.
Further, described microprocessor adopts communication to realize communicating with described backstage monitoring center.
Further, being provided with and the sample pipe connected in case on described monitoring case, be provided with valve on described sample pipe, the liquid outlet place of described sample pipe is configured with the sample bottle matched.
Further, described valve is the electromagnetic valve controlled by microprocessor.
Further, also including the baroceptor for monitoring monitoring point ambient atmosphere pressure, the data feedback that described baroceptor gathers is described microprocessor extremely.
Compared with prior art, the beneficial effects of the present invention is:
(1) present invention contains various monitor and sensor, gathered data are received by microprocessor and process, the result of calculation of microprocessor output is uploaded to backstage monitoring center, staff by backstage monitoring center can realize to monitoring point long-range, automatically monitor, efficiently solving in prior art, subsoil water relies primarily on manpower and monitors the drawback in village of institute on the spot.
(2) subsoil water of monitoring point is evacuated in monitoring case by pump by the present invention, on the one hand, water temperature is measured in monitoring case, on the other hand, subsoil water in monitoring case can carry out sample collecting by sample pipe, the all unified record of the time of institute's collected specimens, place and the water temperature of coupling, water level information is in backstage monitoring center so that the measurement Research work of groundwater quality is more scientific.
Accompanying drawing explanation
Fig. 1 is principles of the invention schematic diagram.
Detailed description of the invention
Below in conjunction with accompanying drawing, the invention will be further described. Embodiments of the present invention include but not limited to the following example.
Embodiment
As it is shown in figure 1, present embodiments provide a kind of subsoil water automatic monitoring system, this monitoring system includes: monitoring case, water temperature monitor, water-level instrumentation, microprocessor, and the backstage monitoring center for United Dispatching, data storage.
So that the present invention is had the understanding more cleaned and understanding by those skilled in the art, below in conjunction with being described in detail:
Monitoring case, is arranged on ground surface, and monitoring case is mainly used in receiving the subsoil water on pump, and the temperature measurement of subsoil water carries out in monitoring case. The shape of monitoring case is not particularly limited, and it can be square, it is also possible to be rectangle, it is contemplated that in monitoring case, subsoil water needs to carry out temperature measurement, and in the present embodiment, monitoring case adopts heat-barrier material to make.
Monitoring case is connected to pump by pipeline, and the other end of pump is connected with subsoil water by pipeline, is evacuated in monitoring case by pump by subsoil water, and after measuring end cycle at one, the subsoil water in monitoring case goes back to underground again through transport pump.
In the present embodiment, being provided with and the sample pipe connected in case, be provided with valve on sample pipe on monitoring case, the liquid outlet place of sample pipe is configured with the sample bottle matched. If within certain measurement cycle, it is necessary to the subsoil water in monitoring case is sampled, then control valve and open, carry out the collection of sample. For the ease of controlling, valve in the present embodiment selects electromagnetic valve, thus in conjunction with the control program of coupling can realize to electromagnetic valve long-range, automatically operate. Sampling carries out within the cycle of certain setting, and the information such as the water temperature of groundwater sample corresponding during employing, water temperature, environmental stress, geographical position, monitoring point is all uploaded to backstage monitoring center by unified.
Water-level instrumentation, for measuring the water level of the subsoil water of monitoring point, water-level instrumentation is existing equipment, and therefore not to repeat here.
Baroceptor, for measuring the atmospheric pressure of monitoring point environment, baroceptor is existing equipment, and therefore not to repeat here.
Microprocessor, mainly has two effects, one, receives the collection data of water-level instrumentation, water temperature monitor and baroceptor and data are processed, its two, the result of the data of reception and process is fed back to background monitoring center. Microprocessor adopts communication to realize communicating with described backstage monitoring center. The concerned control command of backstage monitoring center is assigned by microprocessor, is performed. The on-off action of above-mentioned electromagnetic valve also has microprocessor control.
In the present embodiment, microprocessor is received and gathers data and realized by communication module, and communication module is wireless communication module, can be selected for existing communication module more typically on the market, is not particularly limited at this.
Backstage monitoring center, is made up of some computers, its be mainly used in control command assign, data storage, display etc. Microprocessor adopts communication to realize communicating with described backstage monitoring center.
Based on said structure, staff can in backstage monitoring center to temperature measurement instrument, floodometer, atmospheric sensor, the work of pump and electromagnetic valve carries out the setting of Row control, such as: within a measurement cycle, first staff carries out at background monitoring center presetting corresponding control instruction or operating instruction, after satisfying condition, above-mentioned each parts just run under control of the microprocessor, carry out the collection of data and the sampling of subsoil water, within a measurement cycle, the all data gathered are undertaken processing and calculating by microprocessor, result of calculation and initial data are uploaded to the filing of backstage monitoring center simultaneously. wherein, measure the setting in cycle to need to be determined according to the measurement of time by staff.
According to above-described embodiment, the present invention just can be realized well. What deserves to be explained is; under premise based on above-mentioned design principle; for solving same technical problem; even if some making on architecture basics disclosed in this invention are without substantial change or polishing; the essence of the technical scheme adopted is still the same with the present invention, therefore it should also be as in protection scope of the present invention.
