In general, the water quality test is to investigate the physical properties of water, the chemical components and microorganisms contained in the water, when selecting a water supply source, and when monitoring and monitoring the pollution or purification work of the water source, It is used for various purposes, such as to check the acceptance of water, to measure the environmental pollution of seas, lakes, rivers or rivers, to determine whether the wells are drinkable at public health centers, or to check the pollution of industrial water or sewage. .

For the water quality test, it is necessary to collect samples that can be used as the standard of the whole water quality in the field. If the water quality is deep, such as the sea, lakes, rivers, and rivers, the water quality varies depending on the depth.

The terms used in this specification will be briefly described and the present invention will be described in detail.

While the present invention has been described in connection with what is presently considered to be the most practical and preferred embodiment, it is to be understood that the invention is not limited to the disclosed embodiments. Also, in certain cases, there may be a term selected arbitrarily by the applicant, in which case the meaning thereof will be described in detail in the description of the corresponding invention. Therefore, the terms used in the present invention should be defined based on the meanings of the terms and the contents throughout the present invention, rather than the names of the simple terms.

When an element is referred to as "including" an element throughout the specification, it is to be understood that the element may include other elements, without departing from the spirit or scope of the present invention. In addition, the terms "... unit", "module", etc. described in the specification mean a unit for processing at least one function or operation, which may be implemented in hardware or software or a combination of hardware and software. .

In one embodiment of the present invention, the water collector is a device for collecting water samples. For example, the water collector may be used to collect the seawater in order to measure the temperature, salinity, chemical composition of the seawater, and the conductive water collector, the multi-channel water collector, the insulation water collector, etc. may be used according to the depth of the water to be collected. The conductive water collector collects sample water by dropping messenger from the top of the water collector suspended from the wire and seals the water tank. Sample water is collected at various depths. Insulation collectors are insulated with ebonite or rubber, and the sampler is collected by sealing the collector by messenger drop. The above-described water collection method is only one example, and the water collector may collect the sample water in various ways.

In an embodiment of the present invention, a thermoelectric element is a concept for generically generating an element due to an interaction between heat and electricity. Examples of thermoelectric devices include thermistors, which are elements that use a change in temperature according to electrical resistance, elements that use the Seebeck effect, which is a phenomenon in which electromotive force is generated by temperature differences, and a Peltier effect that absorbs (or generates) heat by current. There is a Peltier element. Thermistors are semiconductor devices whose electrical resistance varies greatly with temperature. NTC thermistors whose electrical resistance decreases with an increase in temperature, and constant temperature coefficient thermistors whose resistance increases with an increase in temperature are used. The Seebeck effect refers to a phenomenon in which electromotive force occurs when the temperature of both ends is different after connecting two types of metals. The Peltier effect is a phenomenon in which one terminal absorbs heat and the other terminal emits heat, depending on the current direction, when current flows after connecting two types of rapid ends. Highly efficient Peltier devices can be obtained by using semiconductors such as bismuth and tellurium that have different electrical conduction methods instead of metals. In case of using Peltier device, the endotherm and heat generation can be controlled according to the direction of current, and the endotherm and heat generation amount are adjusted according to the amount of current.

A compressor is also referred to as a compressor as a device that compresses gas to increase pressure. It is used to control the temperature by compressing the refrigerant in the refrigerator using the principle that the temperature changes in the process of compressing the fluid to change the pressure and speed.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a flowchart illustrating a sample water collection method using an automatic water collector according to an embodiment of the present invention.

In step S110, the number of samples to be used for the water quality test is collected. Depending on the purpose or environment of sampling, the collection method and the timing of collection may be different. As an example, let's take a look at how the timing of collection depends on the purpose or environment of sampling.

In one embodiment, the number of samples may be taken at predetermined intervals. At this time, the period of taking the sample water can be determined in consideration of the spillover effect of the sample water contamination, the transfer rate of the contamination, and the like. For example, tap water sets shorter water collection cycles because of the greater ripple effect of pollution and the faster rate of transmission of pollutants.However, rivers and seawater have less ripple effects due to pollution and slower rate of transmission of pollutants than tap water. You can set the period somewhat longer.

In another embodiment, the sample water can be taken whenever a specific condition is satisfied. In general, sample water is tested for contamination according to various measurement items. The time taken to measure the number of samples may be different for each measurement item, and it may be desirable to inspect the next sample number after inspecting all the measurement items. Therefore, the completion signal indicating that the inspection of the previous sample number is completed can be received from the measurement module corresponding to each measurement item, and the next sample number can be collected when the completion signal is received from all the measurement modules. However, some measurement modules can be set to take the next sample even if the completion signal is not received (for example, the next sample can be checked even if another measurement module is performing the previous sample). have.

In step s120, the first sample water which is a part of the collected sample water is stored in the storage. The reservoir includes a thermostat for maintaining the first sample water at a predetermined temperature. The constant temperature device may be implemented with a cooler and a heater using a compressor or the like, or may be implemented with a thermoelectric element. The user may adjust the thermostat so that the first sample water is maintained at a temperature suitable for overhaul. (For example, 3.9-4.1 degrees)

Table 1 below is an example of the specification of the storage.

Item Specifications Rated voltage 220V / 60HZ Power Consumption 45 W Product capacity 6 bottles Product specification 280 * 540 * 430mm Constant temperature device Semiconductor Compressor (Low Noise Design) Interior lighting O Temperature control range 4 ~ 24 degree Product weight 10kg Etc Double glass adoption

The reservoir illustrated in Table 1 may store six water bottles for collecting sample water, and uses a small refrigerator equipped with a compressor to maintain a constant internal temperature (for example, 4 degrees). However, the storage illustrated in Table 1 above is just one embodiment and may use various types of storage.

In step s130, the second sample water, which is another part of the collected sample water, is transferred to the measuring device. The meter checks the water quality according to predetermined criteria. The measuring device may include at least one measuring module, and each measuring module receives a second sample number sequentially to derive a test result for a corresponding measuring item.

Table 2 below is an example of the items measured by the measuring instrument and the reference value for determining the contamination.

[Table 2] Measurement Items and Reference Values

In step s140, the test result of the second sample water is received from the measuring device.

In step s150, it is determined whether the second sample water is contaminated based on the test result, and when it is determined that the second sample water is contaminated, the control is performed so that a close inspection is performed using the stored first sample water. The inspection may be performed by using another measuring instrument that may perform the inspection more precisely than the measuring instrument used in step s130, or the researchers may manually perform the inspection. On the other hand, when it is determined that the second sample water is not contaminated, the stored first sample water is discharged.

In the conventional automatic water collector, the sample water is collected and then transferred to the measuring device to check for contamination. When the measuring device determines that the sample water is contaminated, the water collecting machine retakes new sample water and performs a detailed inspection. Therefore, when the time required for the inspection of the sample water becomes long, the interval between the number of samples measured by the measuring device and the sampling time of the sample water used for the precision inspection increases greatly. For example, suppose that the meter starts to check whether the sample is taken at 12:00 and the test is completed at 12:30. In this case, the time to judge whether the sample water is contaminated is 12:30 minutes. If the sample water is contaminated, the drawer will take a fresh sample at 12:30 and perform an overhaul. If it is determined that the number of samples collected at 12:00 is contaminated, a detailed inspection is performed using the number of samples collected at 12:30, which causes a problem that the accurate inspection cannot be performed. However, in the present invention, since a part of the sample water taken by the sample water is stored and the precision test is performed using the stored sample water according to the test result of the measuring device, the accurate test can be performed.

In addition, according to an embodiment of the present invention, when the water quality is not contaminated according to the inspection result of the measuring device, the storage space may be efficiently used by discharging the stored sample water.

The reservoir 220 stores the first sample water which is a part of the collected sample water. As described above, the reservoir 220 maintains the temperature of the first sample water by using a thermoelectric element or a cooler and a heater.

The transmitter 230 transmits the second sample water, which is another part of the collected sample water, to the measuring device. The meter may comprise one or more measurement modules, each measuring module checking the second sample number according to a corresponding measurement item.

The receiver 240 receives a test result for the second sample water from the measuring device. The receiver 240 may receive a test result and a completion signal indicating that the test is completed from each measurement module in the measuring device.

If the second sample water is contaminated according to the test result, the controller 250 controls the detailed test to be performed using the stored first sample water. When the second sample water is contaminated, the controller 250 may transmit the first sample water to a precision measurement measuring instrument (not shown) that performs a detailed inspection, or may inform a terminal of the manager of a signal indicating that the detailed sample is required. The control unit 250 may determine whether to perform a close inspection after receiving the measurement results from all the measurement modules, but if it is determined that the possibility of contamination is high after receiving the measurement results from some measurement modules, Even before the measurement result is received, it may be decided to perform a close inspection.

In addition, the controller 250 controls the water collecting unit 210 to control a new sample water to be collected. The controller 250 may control the water collecting unit 210 to collect new sample water every predetermined period, or may control the water collecting unit 210 to collect new sample water whenever a specific condition is satisfied. In particular, when the completion signal is received from all the measurement modules in the measuring unit, the control unit 250 may control the collection unit 210 to take a new sample number.

In addition, when the sample water is not contaminated, the controller 250 controls the reservoir 220 to discharge the stored first sample water.

The preliminary storage tank 320 stores a part of the sample water until the measuring device 340 completes the inspection of the sample water. At this time, it is preferable to keep the temperature of the sample water constant.

Next, when the controller 310 receives the test result from the measuring device 340 and determines that the sample water is contaminated, the controller 310 performs a detailed test using the sample water stored in the preliminary storage tank 320. On the other hand, when it is determined that the sample water is not contaminated, the drain valve 350 is controlled to discharge the sample water stored in the preliminary storage tank 320.
