Description

Technology Field

[0001] The present invention relates to a sample splitter for ecosystem surveys equipped with a counting device that indicates the number of times a sample is split, thereby facilitating sample preparation for environmental analysis and improving reliability. Background Technology

[0003] A sample splitter is a device used to divide collected samples evenly into amounts suitable for analysis, and is used in various fields such as aquatic organism surveys, plankton analysis, and ecosystem surveys. Specifically, the sample splitter is used to obtain a number of individuals or a sample volume suitable for analysis by mixing the collected samples and then repeatedly dividing them at a certain ratio.

[0004] However, when using a sample splitter, users may forget or incorrectly record the number of divisions completed during the process of manually rotating the body to repeat mixing and splitting. In particular, when splitting large volumes of samples multiple times, errors in counting the number of divisions frequently lead to errors in the calculation of sample populations or quantitative analysis results. Furthermore, this problem presents an additional issue of increased user fatigue.

[0005] To solve the above problem, a method may be used in which the user records the number of divisions on a separate record sheet or checks the number of divisions using a manual counting device. However, this method has the problem of reduced work efficiency because the division operation and a separate recording operation must be performed together. In addition, there is a limitation in that it is difficult to accurately manage the number of divisions because the user may omit or duplicate the operation of the counting device while repeating the mixing and division operations.

[0006] Accordingly, there is a growing demand for sample dividers and division methods that allow for the verification of the exact number of divisions while mixing and dividing samples through manual rotational operation by the user, thereby increasing operational efficiency. The present invention aims to improve the reliability of samples for ecosystem surveys and enhance operational efficiency by providing a sample divider for ecosystem surveys with a counter device attached to the outer surface of the body. The problem to be solved

[0008] An ecosystem survey sample splitter equipped with a counting device according to one embodiment of the present invention is proposed to solve the above-mentioned problem. It aims to provide a sample splitter that includes a detachable counting device on the outer surface of the body to automatically record the number of splits, thereby preparing the ecosystem survey sample in a state suitable for analysis and improving the reliability of sample analysis and work efficiency. means of solving the problem

[0010] An ecosystem survey sample splitter equipped with a counting device according to embodiments of the present invention may include: a body that is rotated by a user around a y-axis after a sample is received; a counting device that is detachably attached to the outer surface of the body, wherein the counting device may include: a housing that is detachably attached to the outer surface of the body by a magnet; a posture detection device that generates a posture signal by the rotation of the body; a display that outputs a target number of splits, a current number of splits, and status information of the sample; and a control device that controls the output of the display based on the posture signal.

[0011] Additionally, the body may include a first space positioned on one side with respect to the y-axis and into which the sample is introduced; a second space positioned on the other side with respect to the y-axis; and a third space in contact with the second space in the x-axis direction and separated by a partition wall.

[0012] Additionally, one side of the first space in the z-axis direction may be open, and the second space may be closed by forming a cover on one side in the z-axis direction.

[0013] In addition, the control device can calculate the rotation angle of the body based on the attitude signal and determine whether to proceed with the division cycle of the sample based on the calculated rotation angle of the body.

[0014] In addition, if the rotation angle of the body is greater than or equal to the division threshold angle, the control device can calculate the duration of the state in which the rotation angle of the body is greater than or equal to the division threshold angle and compare it with a preset reference time.

[0015] Additionally, the control device may determine that the division standby state is in place if the duration is less than the reference time, and control the display to maintain the output target division count and the current division count.

[0016] Additionally, the control device may determine that the division cycle is in progress if the duration is longer than or equal to the reference time, and control the display so that the current number of divisions is maintained and a division progress notification is output until the division cycle is completed.

[0017] In addition, the control device may determine that the division cycle is completed when the rotation angle of the body recovers to a return threshold angle or lower, and control the display so that a value increased by one from the previous current division count is output as the new current division count.

[0018] In addition, the control device can control the display so that a division completion notification is output when the new current number of divisions becomes equal to the target number of divisions.

[0019] In addition, the control device can determine whether the body reciprocates in one direction and the other direction with respect to the y-axis within a range less than the division threshold angle if the rotation angle of the body is less than the division threshold angle.

[0020] Additionally, the control device may determine that the sample is in a mixing progress state when the body is reciprocally rotated in one direction and the other direction within a range less than the division threshold angle, calculate the number of reciprocal rotations of the body, and control the display to output the output along with the target number of divisions and the current number of divisions. Effects of the invention

[0022] An ecosystem survey sample splitter equipped with a counting device according to one embodiment of the present invention includes a counting device detachably attached to the outer surface of the body, and by automatically recording the number of splits, it is possible to prepare the ecosystem survey sample in a state suitable for analysis and improve the reliability and work efficiency of the sample analysis.

[0030] The present invention relates to a sample splitter for ecosystem analysis, and more specifically, to a device in which a counting device is attached to the outer surface of the body so that the number of splits is automatically counted during the splitting process.

[0031] Specifically, a counter device attached to the outer surface of the body counts the number of divisions based on the body's rotation angle, the duration of the rotated state, and whether the body returns to its initial state. Accordingly, the sample splitter for ecosystem surveys according to the present invention is a simple device that determines whether the division is in progress or completed through multiple criteria, thereby improving the reliability of sample analysis for ecosystem surveys.

[0032] Furthermore, it allows the user to fully concentrate on mixing and splitting the samples, thereby improving work efficiency. In addition, since there is no need to operate the equipment with gloves coated with the sample fixative, the durability of the equipment is improved and sample contamination is prevented.

[0033] Hereinafter, the sample splitter for ecosystem survey equipped with the counting device of the present invention will be described in detail.

[0035] FIG. 1 is a schematic diagram showing a sample splitter for ecosystem survey according to one embodiment of the present invention. Referring to FIG. 1, the sample splitter (10) for ecosystem survey may include a body (100) in which a sample is received and a counting device (200) that is detachably attached to the outer surface of the body (100).

[0036] The body (100) can be rotated by a user around the y-axis after a sample is received. Specifically, the user can rotate the body (100) in one direction and the other direction with the y-axis as the central axis to mix or divide the sample received in the body (100). Here, the sample may be a sample containing aquatic organisms, plankton, zooplankton, or a mixture thereof in water collected for ecosystem surveys. Accordingly, the body (100) can function as a container that receives the collected sample and performs mixing and dividing of the sample according to the user's rotation operation.

[0037] The body (100) may form a space within which a sample can move. For example, the body (100) may be made of a transparent or translucent material. For example, the body (100) may be made of one or more materials selected from synthetic resin, acrylic, polycarbonate, or glass, but is not limited thereto. Thus, the user can check from the outside the state in which the sample moves or is divided inside the body (100).

[0038] The body (100) may include a first space (110), a second space (120), a third space (130), a partition (140), and a cover (150). The first space (110), the second space (120), and the third space (130) may be formed inside the body (100). Additionally, the first space (110), the second space (120), and the third space (130) may be spaces where a sample can be mixed or distributed according to the rotational direction and tilt change of the body (100).

[0039] The first space (110) is positioned on one side with respect to the y-axis and can be fed a sample. Specifically, the first space (110) may have one side in the z-axis direction open. For example, the first space (110) may have the upper surface in the z-axis direction open. Thus, the user can feed the sample into the body (100) through the upper surface of the first space (110). Afterward, the user can feed the collected sample into the first space (110) and then rotate the body (100) with respect to the y-axis to mix and divide the sample.

[0040] The second space (120) may be positioned on the other side with respect to the y-axis. Additionally, the second space (120) may be in contact with the first space (110) in the y-axis direction and connected to each other. Accordingly, while mixing and splitting operations are performed by the rotation of the body (100), the sample may move between the first space (110) and the second space (120). For example, when the body (100) is rotated in the direction of the other side of the y-axis, at least a portion of the sample located in the first space (110) may be moved to the second space (120) side by gravity. Details regarding the mixing and splitting operations of the body (100) will be explained in detail below in the description of the count device (200).

[0041] The third space (130) is positioned on the other side with respect to the y-axis and can be in contact with the first space in the y-axis direction. Additionally, the third space (130) can be in contact with the second space (120) in the x-axis direction and can be separated from the second space (120) by a partition wall (140). At this time, the third space (130) and the first space (110) can be connected to each other.

[0042] Accordingly, the sample may be mixed while moving between the first space (110) and the second space (120) or between the first space (110) and the third space (130) during repeated mixing operations of the body (100). During the splitting operation of the body (100), the sample may be divided and received in the second space (120) and the third space (130). At this time, the sample received in the second space (120) is a residual sample used for subsequent mixing and splitting, and the sample received in the third space (130) may be a discharge sample that is discharged to the outside or recovered.

[0043] Meanwhile, one side of the third space (130) in the z-axis direction may be selectively opened or closed by an opening / closing flap (160). Specifically, the opening / closing flap (160) is rotatably connected to the outer wall of the body (100) and can cover the upper surface of the third space (130). Additionally, the opening / closing flap (160) may be opened along the rotational direction of the body (100) when the body (100) is rotated beyond a split critical angle. At this time, the opening / closing flap (160) may be rotated only to a position parallel to the upper surface of the third space (130) by means of a movement prevention ridge (not shown) formed in the partition wall (140).

[0044] Accordingly, the opening / closing flap (160) can function as a passage to prevent liquid samples from splashing out during the sample mixing process and to guide the movement of samples contained in the third space (130) to the recovery container during the sample splitting process.

[0045] However, not limited thereto, in other embodiments, the third space (130) may be opened without including an opening / closing flap (160) in the z-axis direction.

[0046] A partition wall (140) is positioned between the second space (120) and the third space (130) so that the sample can be divided and distributed into the second space (120) and the third space (130), respectively. At this time, the partition wall (140) can partition the second space (120) and the third space (130) so that they have the same internal volume. Accordingly, the body (100) can divide the sample into the second space (120) and the third space (130) by the user's rotational operation and gravity without a separate complex structure.

[0047] The first space (110) may be open on one side in the z-axis direction. On the other hand, the second space (120) may be closed by forming a cover (150) on one side in the z-axis direction. That is, the first space (110) may be connected to the outside, while direct connection to the outside of the second space (120) may be restricted by the cover (150). Meanwhile, the third space (130) may have its upper surface (one side in the z-axis direction) closed by an opening / closing flap (160) during the sample mixing process and its upper surface opened during the sample recovery process.

[0048] The cover (150) may be positioned to cover one side of the second space (120) in the z-axis direction. Specifically, the cover (150) may be formed to cover the entire upper surface of the second space (120). Accordingly, the cover (150) can prevent the sample located in the second space (120) from being discharged to the outside during the division operation of the body (100), thereby allowing the sample to remain stably in the second space (120). Accordingly, the user can stably secure the remaining sample during the repeated mixing and division process.

[0049] The count device (200) can be detachably attached to the outer surface of the body (100). Specifically, the count device (200) can be attached to the top of the outer surface of the body (100). The count device (200) can be positioned to accurately detect the rotational state of the body (100).

[0050] For example, the count device (200) may be positioned at a location corresponding to the boundary between the first space (110) and the second space (120) or between the first space (110) and the third space (130) on the outer surface of the body (100). Accordingly, the count device (200) can reliably detect the overall rotational state of the body (100) and reduce errors caused by local impact or shaking occurring at one end of the body (100).

[0051] The count device (200) can be detachably attached to the outer surface of the body (100) by means of a magnet. Thus, the user can attach the count device (200) to the body (100) or detach it from the body (100) as needed.

[0052] The counter device (200) can generate an attitude signal by rotating the body (100). Additionally, the counter device (200) can determine the rotation angle of the body (100), the duration of the rotated state, and whether to return based on the attitude signal. Accordingly, the counter device (200) can determine whether the sample division cycle is completed and output the current number of divisions and status information based on the determination result. The specific operation method of the counter device (200) will be explained in detail below with reference to FIG. 4.

[0053] Accordingly, the sample splitter (10) for ecosystem survey according to one embodiment of the present invention can mix and split the sample by rotating the user, and automatically display the number of splits completed so far through the count device (200). Therefore, the sample splitter (10) for ecosystem survey according to one embodiment can help reduce forgetting or errors in the number of splits and help prepare the sample for ecosystem survey in a state suitable for analysis.

[0055] FIG. 2 is an exploded view illustrating a count device for an ecosystem survey sample splitter according to an embodiment of the present invention. Referring to FIG. 2, the count device (200) may include a housing (210), a posture detection device (220), a display (230), a control device (240), and a magnet (250). FIG. 2 shows the display (230), the control device (240), and the posture detection device (220) arranged sequentially, but the arrangement order of the control device (240) and the posture detection device (220) may be reversed.

[0056] The count device (200) can detect the rotational state of the body (100) including the above components and output the number of times the sample is divided and state information based on the detected rotational state. Additionally, the count device (200) can be detachably attached to the outer surface of the body (100).

[0057] The housing (210) can form the external shape of the counting device (200). The housing (210) can accommodate or support a display (230), an attitude detection device (220), and a control device (240). For example, the housing (210) includes a front housing (210A) and a rear housing (210B), and a display (230) can be placed in the front housing (210A).

[0058] The rear housing (210B) may be positioned to be in direct contact with the outer surface of the body (100). Here, a magnetic member (not shown) coupled with a magnet (250) may be disposed on at least a portion of the rear housing (210B). The magnetic member may comprise one or more materials selected from iron, stainless steel, magnetic metal plates, or magnetic alloys. Thus, the housing (210) may be detachably attached to the outer surface of the body (100) by the magnet (250).

[0059] In one embodiment, most of the housing (210) is formed of a material that is waterproof or chemically resistant, and a magnetic member may be placed only in a portion of the rear housing (210B). For example, the housing (210) may include a synthetic resin, silicone, a rubber packing, or a waterproof coating layer. Accordingly, the housing (210) can prevent a sample, washing water, or sample fixative from entering the interior of the count device (200).

[0060] The rear housing (210B) has a magnetic member disposed in only a portion of the area, so that it can be magnetically coupled with the magnet (250) with the outer wall of the body (100) in between. Specifically, the magnet (250) is included in the counting device (200) and can be magnetically coupled with the magnetic member of the rear housing (210B) with the outer wall of the body (100) in between at a location separated from the housing (210). Accordingly, the housing (210) can be detachably fixed to the outer surface of the body (100). Here, since the magnetic member is disposed spaced apart from the attitude detection device (220) and the control device (240), the error in the attitude signal or the instability of the electronic component operation caused by the magnetic field can be reduced.

[0061] Replacement and maintenance can be easily performed due to the above-described structure of the count device (200). Specifically, the user can detach the count device (200) when washing the body (100) after the sample splitting operation, thereby reducing the exposure of the electronic components of the count device (200) to washing water or sample fixative.

[0062] The count device (200) may further include a reset button (211), a mode button (212), and a setting button (213). Here, the reset button (211), the mode button (212), and the setting button (213) may be placed on the outer surface of the housing (210). This will be explained in detail below with reference to FIG. 3.

[0063] The attitude detection device (220) can generate an attitude signal by the rotation of the body (100). Specifically, the attitude detection device (220) can generate an attitude signal corresponding to the rotational state of the body (100) by rotating together with the body (100) while the counting device (200) is attached to the body (100). Here, the attitude signal may include information regarding at least one of the rotation angle, tilt, angular velocity, or acceleration of the body (100).

[0064] The posture detection device (220) may be placed inside the housing (210). For example, the posture detection device (220) may be placed on a circuit board. In this case, the posture detection device (220) may be positioned in a direction that can reliably detect the rotational state of the body (100) while the counting device (200) is attached to the outer surface of the body (100).

[0065] The attitude detection device (220) may include an inertial measurement unit (IMU). For example, the attitude detection device (220) may include a 6-axis inertial measurement unit (IMU), an accelerometer, a gyroscope, or a combination thereof. Here, the accelerometer can detect a change in the tilt of the body (100) with respect to the direction of gravity, and the gyroscope can detect a change in the rotational angular velocity of the body (100). Accordingly, the attitude detection device (220) may generate an attitude signal corresponding to the rotation of the body (100) by including the above components. The attitude detection device (220) may transmit the generated attitude signal to a control device (240) to provide a signal for the control device (240) to calculate the rotation angle of the body (100).

[0066] A display (230) may be positioned on the front of the housing (210). Specifically, the display (230) may be positioned on the outer surface of the front housing (210A) to output the target number of divisions, the current number of divisions, and status information of the sample. Here, the display (230) may include, but is not limited to, a liquid crystal display, an organic light-emitting diode display, a segment display, or a small electronic display.

[0067] The control device (240) may be placed in the internal space of the housing (210). The control device (240) can determine the rotation and state of the body based on the attitude signal and control the output of the display (230). Specifically, the control device (240) can receive an attitude signal from the attitude detection device (220) and calculate the rotation angle of the body (100) based on the received attitude signal. In addition, the control device (240) can determine whether the sample's splitting cycle is completed by comparing the calculated rotation angle with the splitting threshold angle or the return threshold angle.

[0068] The control device (240) may include a microcontroller, a processor, an integrated circuit, or a control circuit board. Additionally, the control device (240) is electrically connected to the attitude detection device (220) and can process the attitude signal generated by the attitude detection device (220). Additionally, the control device (240) is electrically connected to the display (230) and can control the target number of divisions, the current number of divisions, and status information to be output to the display (230). Accordingly, the sample splitter (10) for ecosystem survey of the present invention can prevent forgetting and miscounting of the number of divisions during the repetitive sample division process, and can prepare the collected sample in a state suitable for analysis, thereby improving the accuracy of sample analysis.

[0070] FIG. 3 is a drawing illustrating a display of a sample splitter for ecosystem survey according to an embodiment of the present invention. Referring to FIG. 3, a display (230), a reset button (211), a mode button (212), and a setting button (213) may be arranged on the outer surface of a count device (200).

[0071] A display (230) may be placed on the front housing (210A). The display (230) may include a division count display area (231) and a status display area (232). The division count display area (231) may be an area that outputs the target division count and the current division count of the sample. The status display area (232) may be an area that outputs the operating status of the sample for the division process. Thus, the user can check the division progress status and the operating status of the sample during the mixing and division operation of the sample.

[0072] The division count display area (231) may be an area that outputs the target division count and the current division count. Here, the target division count may be a value pre-set by the user as the number of divisions required for sample analysis. In this case, the target division count may be a value that does not change from the time the user pre-sets until the reset button (211) is pressed. The current division count may be a value indicating the number of divisions completed up to the current time. In this case, the current division count may be a value that is updated when the division cycle is determined to be completed by the count device (200).

[0073] For example, the division count display area (231) can output the current division count and the target division count separately. Specifically, if the target division count is 10 and the current division count is 3, the division count display area (231) can output the target division count "10". Additionally, the division count display area (231) can output the current division count "3". However, it is not limited to this, and the division count display area (231) can display the current division count and the target division count in one or more ways such as ratios, graphs, symbols, or colors.

[0074] The status display area (232) can output status information of the sample. For example, the status display area (232) can output a mixing progress status, a splitting waiting status, a splitting progress status, and a splitting completion notification. Additionally, the status display area (232) can further output the number of mixing cycles or the remaining rotation angle during the mixing process.

[0075] For example, the status display area (232) can output the number of round-trip rotations as the number of mixtures along with the phrase "mixed" in the mixing progress state. Additionally, the status display area (232) can output the phrase "waiting" in the splitting waiting state and the phrase "split" in the splitting progress state. Furthermore, the status display area (232) can output the phrase "completed" in the splitting completed state.

[0076] Meanwhile, the control device (240) can calculate the difference between the splitting threshold angle and the rotation angle of the body (100) in the mixing progress state and control it to output this as the remaining rotation angle in the status display area (232). Details regarding the remaining rotation angle will be explained in detail below with reference to FIG. 4.

[0077] Meanwhile, the target number of divisions, the current number of divisions, and the status information displayed on the display (230) can be adjusted by buttons placed on the housing.

[0078] The reset button (211) may be an input device for initializing the output value of the display (230) or the operating state of the count device (200). For example, the reset button (211) may be used to initialize the current number of divisions to 0. Additionally, the reset button (211) may be used to change the target number of divisions, state information, or mixing count to an initial state.

[0079] The mode button (212) may be an input device for changing the output mode of the display (230). For example, when a user presses the mode button (212), a setting screen for setting the target number of divisions, the division threshold angle, the return threshold angle, and the reference time may be displayed sequentially in the status display area (232). Accordingly, the user can change the setting value of the selected item by selecting the item to be set and then pressing the setting button (213). Afterward, the user can confirm the setting value of the selected item by pressing the mode button (212) once more after changing the setting value.

[0080] The setting button (213) may be an input device for setting the target number of divisions or the conditions for completing the division cycle. For example, the user can pre-set the target number of divisions, the division threshold angle, the return threshold angle, and the reference time using the setting button (213). Additionally, the user can set the division threshold angle, the return threshold angle, or the reference time using the setting button (213).

[0081] In one embodiment, the setting button (213) may include a plurality of input buttons. For example, the setting button (213) may include a first setting button for increasing the setting value and a second setting button for decreasing the setting value. Accordingly, the user can adjust the target number of divisions, the division threshold angle, the return threshold angle, and the reference time, respectively, according to the amount of the sample, the viscosity of the sample, the division operation conditions, or the user's operation method.

[0083] FIG. 4 is a diagram illustrating the process of a control device for an ecosystem survey sample splitter according to an embodiment of the present invention determining the completion of a splitting cycle. Referring to FIG. 4, the method (S100) of the control device (240) determining the completion of a splitting cycle may include the steps of: acquiring a posture signal (S101); calculating a rotation angle of the body (S102); determining whether the rotation angle of the body is greater than or equal to a splitting threshold angle (S103); determining whether reciprocating rotation is possible (S104); transmitting a mixing notification signal to a display (S105); transmitting a first output signal to a display (S106); determining whether the calculated duration is greater than or equal to a reference time (S107); transmitting a splitting notification signal to a display (S108); determining whether the rotation angle of the body is less than or equal to a return threshold angle (S109); transmitting a count signal to a display (S110); transmitting a second output signal to a display (S111); and transmitting a third output signal to a display (S112). FIG. 4 illustrates steps S101 to S112 being performed sequentially, but is not limited thereto, and some steps may be changed, some steps omitted, or new steps added. For example, a step of setting the target number of divisions, the division threshold angle, the return threshold angle, or the reference time may be performed before step S101 is performed. Additionally, after step S110, a step of determining whether the new current number of divisions is equal to the target number of divisions and outputting a division completion notification may be performed further.

[0084] Referring to FIG. 4, the control device (240) can calculate the rotation angle of the body (100) based on the posture signal generated by the posture detection device (220) and determine the rotation angle of the body (100) by comparing the calculated rotation angle with a preset reference value. Additionally, the control device (240) can transmit a mixed notification signal, a split notification signal, a count signal, a first output signal, a second output signal, or a third output signal to the display (230) according to the rotation angle of the body (100). Furthermore, the display (230) can output the target number of splits, the current number of splits, and status information.

[0085] The step of acquiring a posture signal (S101) is a step in which the control device (240) receives a posture signal from the posture detection device (220). Specifically, in step S101, the control device (240) can acquire a posture signal generated by the posture detection device (220) by the rotation of the body (100). Here, the posture signal may include information regarding at least one of the tilt, rotation angle, angular velocity, or acceleration of the body (100).

[0086] The step of calculating the rotation angle of the body (S102) is a step in which the control device (240) calculates the rotation angle of the body (100) based on the attitude signal. For example, in step S102, the control device (240) may calculate the rotation angle of the body (100) by using tilt information regarding the direction of gravity included in the attitude signal or by using angular velocity information included in the attitude signal. Here, the rotation angle of the body (100) may refer to the angle in which the body (100) is rotated with the y-axis as the central axis from an initial state or a state that is horizontal with respect to the xy plane. In addition, in one embodiment, the rotation angle of the body (100) may be an acute angle.

[0087] The step (S103) of determining whether the rotation angle of the body is greater than or equal to the division threshold angle is a step of determining whether the body (100) has reached a posture for division progress by comparing the rotation angle of the body (100) calculated by the control device (240) with the division threshold angle. Here, the division threshold angle may be a reference angle for determining whether the body has reached a posture for division.

[0088] For example, if the rotation angle of the body (100) is greater than or equal to the division threshold angle, the control device (240) may determine that the body (100) has been rotated to an angle sufficient for division to proceed. On the other hand, if the rotation angle of the body (100) is less than the division threshold angle, the control device (240) may determine that the body (100) is in a mixing proceeding state or a transition state for proceeding with the next operation.

[0089] The step of determining whether reciprocating rotation occurs (S104) is a step in which, when the rotation angle of the body (100) is less than the division threshold angle, the control device (240) determines whether the rotation direction of the body (100) is repeatedly switched from one side direction to the other side direction. Specifically, in step S104, when the rotation angle of the body (100) is less than the division threshold angle, the control device (240) determines whether the body (100) reciprocates in one side direction and the other side direction with respect to the y-axis within the range less than the division threshold angle.

[0090] For example, in step S104, the control device (240) can determine whether the rotation direction of the body (100) repeatedly switches between one direction and the other direction with respect to the y-axis. At this time, the one direction and the other direction may be opposite directions with respect to the y-axis. The control device (240) can calculate the number of reciprocating rotations by accumulating the rotation direction switching pattern of the body (100). And if the calculated number of reciprocating rotations is greater than or equal to a preset number, the control device (240) determines that the body (100) is reciprocating, and determines the state as a mixing progress state in which a sample is being mixed. In one embodiment, the preset number may be 2 times, but is not limited thereto.

[0091] On the other hand, if the calculated number of reciprocating rotations is less than a preset number, the control device (240) determines that the body (100) does not reciprocate and can determine the state as a transition state for proceeding with the next operation. At this time, the control device (240) may additionally perform a step of calculating the difference between the division threshold angle of the body (100) and the rotation angle of the body (100).

[0092] The step of transmitting a mixing notification signal to the display (S105) is a step in which the control device (240) controls the display (230) to display the mixing progress status. Specifically, in step S105, if the control device (240) determines that the body (100) is reciprocating, it may transmit a mixing notification signal to the display (230). The display (230) may receive the mixing notification signal and output a notification related to the mixing progress status in the status display area (232). Additionally, the output target number of divisions and the current number of divisions may be maintained in the division count display area (231) of the display (230).

[0093] Additionally, the control device (240) can transmit a mixing notification signal to control the number of reciprocating rotations calculated below the notification regarding the mixing progress status to be displayed together in the status display area (232) of the display (230). Thus, the user can check the degree of mixing of the sample and prepare a uniform analysis sample by mixing the sample the same number of times in each division process.

[0094] The step of transmitting a first output signal to a display (S106) is a step in which the control device (240) controls the display (230) to maintain the target number of divisions and the current number of divisions displayed on the display (230). Specifically, the control device (240) may transmit a first output signal to the display (230) when it determines that the body (100) is not reciprocating. Then, the display (230) may receive the first output signal and maintain the target number of divisions and the current number of divisions displayed on the division count display area (231).

[0095] Additionally, the display (230) can receive a first output signal and output the remaining rotation angle to the status display area (232). Thus, the user can check the remaining rotation angle information for reaching the division threshold angle.

[0096] The step (S107) of determining whether the duration is greater than or equal to a reference time is a step in which the control device (240) compares the time during which the state in which the rotation angle of the body (100) is greater than or equal to a division threshold angle is maintained with a preset reference time. Specifically, in step S107, if the rotation angle of the body (100) is greater than or equal to a division threshold angle, the control device (240) can calculate the duration during which the state is maintained.

[0097] In step S107, the control device (240) may determine that the splitting cycle is in progress if the calculated duration is greater than or equal to the reference time. On the other hand, in step S107, if the calculated duration is less than the reference time, the control device (240) may determine that it is in a waiting state for splitting or a temporary change in angle. Therefore, the control device (240) can minimize counting errors by determining whether the splitting cycle is in progress by considering the rotation angle and the duration for which the body (100) is rotated together.

[0098] The step of transmitting a split notification signal to the display (S108) is a step in which the control device (240) controls the display (230) to display a notification related to the split progress status. Specifically, in step S108, the control device (240) may transmit a split notification signal to the display (230) if the duration calculated in step S107 is greater than or equal to a reference time. Subsequently, the display (230) may receive the split notification signal and output a notification related to the split progress status in the status display area (232). At this time, the control device (240) may control the display (230) so that the target number of splits and the current number of splits displayed in the split count display area (231) are maintained until the split cycle is completed.

[0099] The step (S109) of determining whether the rotation angle of the body is less than or equal to the return threshold angle is a step in which the control device (240) compares the rotation angle of the body (100) with the return threshold angle. Specifically, in step S109, the control device (240) can determine whether the body (100) has recovered to an initial state or a horizontal state after the duration during which the rotation angle of the body (100) is greater than or equal to the division threshold angle has been maintained for a reference time or longer. Here, the return threshold angle may be a reference angle for determining whether the body (100) has recovered to an initial state or a horizontal state parallel to the xy plane.

[0100] In step S109, if the rotation angle of the body (100) recovers to a return threshold angle or lower, the control device (240) may determine that the body (100) has returned to an initial state and the splitting cycle is completed. On the other hand, if the rotation angle of the body (100) in step S109 exceeds the return threshold angle, the control device (240) may determine that the splitting cycle is in progress.

[0101] The step of transmitting a count signal to the display (S110) is a step in which the control device (240) controls the display (230) to update the current number of divisions. Specifically, in step S110, when the rotation angle of the body (100) recovers to a return threshold angle or lower, the control device (240) can transmit a count signal to the display (230) so that a value increased by one from the previous current number of divisions is output as the new current number of divisions.

[0102] For example, the control device (240) can control the display (230) so that when the division cycle is completed with "5" displayed as the previous current division count, "6" is displayed as the new current division count.

[0103] Accordingly, the control device (240) updates the current number of divisions only when the body (100) has recovered to a return threshold angle or lower, thereby preventing the current number of divisions from increasing redundantly before one division operation is completed and improving the accuracy of the division count counting.

[0104] Meanwhile, after completing step S110, the control device (240) may proceed to a step of determining whether the new current number of divisions becomes equal to the target number of divisions. If the new current number of divisions becomes equal to the target number of divisions, the control device (240) may control the display (230) to output a notification regarding the completion of division. Accordingly, the user can intuitively check whether the target number of divisions has been reached during the division operation.

[0105] The step of transmitting a second output signal to the display (S111) is a step in which the control device (240) controls the current number of divisions and the division progress notification displayed on the display (230) to be maintained. Specifically, in step S111, if the rotation angle of the body (100) exceeds the return threshold angle, the control device (240) can transmit a second output signal to the display (230) to control the current number of divisions displayed in the division count display area (231) to be maintained. Additionally, the control device (240) can control the division progress notification displayed in the status display area (232) to be maintained. Accordingly, the control device (240) can maintain the current number of divisions until the body (100) recovers to below the return threshold angle. Thus, the control device (240) can prevent the current number of divisions from being updated before the division cycle is completed and can improve the accuracy of the division count counting.

[0106] The step of transmitting a third output signal to the display (S112) is a step in which the control device (240) controls the display (230) to output a notification related to the division waiting state. Specifically, in step S112, the control device (240) may transmit a third output signal to the display (230) if the duration of the state in which the rotation angle of the body (100) is greater than or equal to the division threshold angle is less than the reference time. Then, the display (230) may receive the third output signal and output a notification related to the division waiting state in the status display area (232). At this time, the control device (240) may control the display (230) so that the current number of divisions displayed in the division count display area (231) is maintained. Accordingly, in step S112, the control device (240) can prevent the current number of divisions from increasing even if the rotation angle of the body (100) changes to greater than the division threshold angle due to temporary tilting.

[0108] By the method described above, the sample splitter (10) for ecosystem survey according to one embodiment can automatically count the number of splits using simple equipment, thereby preparing a sample suitable for ecosystem survey and improving the accuracy of ecosystem analysis. In addition, by counting the number of splits in a non-contact manner, contamination of the sample and equipment is prevented, and the concentration of the splitting task can be improved.

[0109] Hereinafter, with reference to FIGS. 5 to 7, an example of use of a sample splitter (10) for ecosystem investigation according to one embodiment will be specifically described.

[0111] FIGS. 5 to 7 are exemplary drawings sequentially illustrating the splitting process of a sample splitter for ecosystem survey according to one embodiment of the present invention.

[0112] FIG. 5 is an exemplary drawing showing a state in which the body of a sample splitter for ecosystem investigation according to one embodiment of the present invention is rotated to a state less than the splitting critical angle. Referring to FIG. 5, the body (100) can be rotated in one direction and the other direction with respect to the y-axis from an initial state. At this time, the rotation angle (α) of the body (100) shown in FIG. 5 may be less than the splitting critical angle.

[0113] For example, if the splitting critical angle is 80 degrees and the user repeatedly reciprocates the body (100) at an angle of 30 to 60 degrees, the sample can flow and be mixed between the first space (110), the second space (120), and the third space (130).

[0114] Meanwhile, the control device (240) can calculate the rotation angle (α) of the body (100) based on the posture signal generated by the posture detection device (220). And if the rotation angle (α) is less than 80 degrees, the control device (240) can determine whether the body (100) is reciprocating within a range of less than 80 degrees. If the control device (240) determines that the body (100) is reciprocating, it determines that the sample is in a mixing progress state and can transmit a mixing notification signal to the display (230).

[0115] Additionally, the control device (240) can calculate the number of reciprocating rotations of the body (100) and use this as the number of mixtures. The control device (240) can also transmit a mixture notification signal to the display (230) to control the display so that a notification related to the mixing progress status and the number of mixtures are displayed in the status display area (232). At this time, the display (230) can receive the mixture notification signal and maintain the output state of the target number of divisions and the current number of divisions displayed in the division count display area (231).

[0116] Accordingly, the user can check and adjust the degree of mixing of the sample. In addition, the bias of biological individuals included in the sample is reduced, and the representativeness of the sample for analysis can be improved during the subsequent partitioning process.

[0117] On the other hand, if the control device (240) determines that the body (100) is not reciprocating, it can transmit a first output signal to the display (230) to control the maintenance of the target number of divisions and the current number of divisions displayed in the division count display area (231). Additionally, the control device (240) can control the display of remaining angle information in the status display area (232).

[0119] FIG. 6 is an exemplary drawing showing the state in which the body of a sample splitter for ecosystem investigation according to one embodiment of the present invention is rotated beyond the splitting critical angle. Referring to FIG. 6, the body (100) can be rotated to reach a position for splitting with respect to the y-axis. At this time, the rotation angle (β) of the body (100) may be greater than the splitting critical angle.

[0120] For example, if the splitting critical angle is 80 degrees and the user tilts the body (100) by 85 degrees in the opposite direction relative to the y-axis, where the second space (120) and the third space (130) are arranged, the sample can move to the second space (120) and the third space (130) of the body (100). At this time, the partition wall (140) can separate the second space (120) and the third space (130) to guide the sample to be divided and located in different spaces.

[0121] At this time, since a cover (150) is formed on one side (upper surface) in the z-axis direction of the second space (120), the sample located in the second space (120) can be prevented from leaking out even if the body (100) is rotated significantly. Therefore, the sample remains in the second space (120) and can be used for subsequent splitting or analysis.

[0122] On the other hand, an opening / closing flap (160) may be disposed on one side (upper surface) in the z-axis direction of the third space (130). The opening / closing flap (160) may be opened along the rotational direction of the body (100) when the body (100) is rotated at an angle greater than the splitting critical angle, and accordingly, the sample contained in the third space (130) may be guided to the outside or to a recovery container along the opening / closing flap (160).

[0123] Alternatively, one side (upper surface) of the third space (130) in the z-axis direction may be open. Accordingly, when the body (100) is rotated at an angle greater than the splitting critical angle, the sample contained in the third space (130) may be discharged to the outside.

[0124] Meanwhile, if the rotation angle (β) of the body (100) is greater than or equal to the division threshold angle, the control device (240) can calculate the duration of the state and compare the calculated duration with a preset reference time.

[0125] Specifically, the control device (240) may determine that the split standby state is less than the reference time when the calculated duration is less than the reference time. For example, if the reference time is 2 seconds and the calculated duration is 1 second, the control device (240) may transmit a third output signal to the display (230) to control the output of a notification related to the split standby state in the status display area (232). At this time, the control device (240) may control the display (230) so that the current number of splits displayed in the split count display area (231) is maintained.

[0126] On the other hand, the control device (240) can determine that the splitting progress state is in progress if the calculated duration is greater than or equal to the reference time. For example, if the reference time is 2 seconds and the calculated duration is 2 seconds or more, the control device (240) can transmit a splitting progress notification signal to the display (230) to control the splitting progress state to be displayed in the status display area (232) of the display (230). At this time, the control device (240) can control the display (230) so that the current number of splits displayed in the split count display area (231) is maintained until the splitting cycle is completed.

[0128] FIG. 7 is an exemplary drawing showing the state in which the body of a sample splitter for ecosystem investigation according to one embodiment of the present invention has returned to a state below the return threshold angle. Referring to FIG. 7, the body (100) can return to a state close to an initial state or a horizontal state from a position for splitting. At this time, the rotation angle (γ) of the body (100) may be below the return threshold angle.

[0129] Here, the return critical angle may be a reference angle for determining whether the body (100) has recovered to an initial state or a horizontal state parallel to the xy plane.

[0130] For example, if the return threshold angle is 10 degrees and the rotation angle of the body (100) recovers to 5 degrees, the control device (240) can determine that the division cycle is completed. Then, the control device (240) can transmit a count signal to the display (230) to control the output of a value that is increased by one from the previous current division count as the new current division count.

[0131] On the other hand, if the rotation angle of the body (100) exceeds the return threshold angle, the control device (240) may determine that the split cycle has not been completed.

[0132] For example, if the return threshold angle is 10 degrees and the rotation angle of the body (100) has recovered to 20 degrees, the control device (240) can determine that the division cycle is in progress. The control device (240) can control the display (230) so that the current number of divisions is maintained until the rotation angle of the body (100) becomes 10 degrees or less, and a division progress status notification is output. Accordingly, the control device (240) can prevent duplicate increases in the current number of divisions and improve the accuracy of the calculation of the number of divisions by updating the current number of divisions only when the body (100) has recovered to a return threshold angle or less.

[0134] As such, the sample splitter (10) for ecosystem investigation according to the present invention can automatically update the number of splits by determining whether to split based on the rotation angle of the body (100) and the time the body (100) has been rotated. Accordingly, the user can perform repetitive sample splitting operations without operating a separate manual counting device, prevent errors in counting the number of sample splits, and have the effect of preparing the collected sample in a state suitable for analysis.

[0136] Meanwhile, another embodiment of the present invention may be implemented as an electronic count device (200) that is detachably attached to a body (100) that is rotated by a user around the y-axis after a sample is received. Here, the count device (200) may include a housing (210) that is detachably attached to the outer surface of the body (100) by a magnet (250), a posture detection device (220) that detects the rotational state of the body (100) and generates a posture signal, a control device (240) that determines the rotation angle, rotation duration, and return status of the body based on the posture signal, and a display (230) that outputs target number of divisions, current number of divisions, and status information according to the determination result of the control device (240). Accordingly, the count device (200) is an electronic device separate from the body (100) that directly receives the sample, and can detect the rotational movement of the body (100) and automatically display the number of divisions and the division status.

[0138] Although the sample splitter (10) for ecosystem investigation according to the embodiment of the present invention has been described as a specific embodiment, this is merely an example and the present invention is not limited thereto, and should be interpreted as having the broadest scope in accordance with the basic concept disclosed in this specification. A person skilled in the art may implement unspecified embodiments by combining or substituting the disclosed embodiments, and this also does not deviate from the scope of the rights of the present invention. In addition, a person skilled in the art may easily change or modify the disclosed embodiments based on this specification, and it is evident that such changes or modifications also fall within the scope of the rights of the present invention.
