Utilize the equipment of aquatic organism monitoring water quality

The present invention relates to utilize aquatic organism to observe the water quality monitoring equipment of the water quality of natural water, wherein natural water (raw water) is introduced into water tank with the breed aquatic organism, and water tank carries out image analysis by shooting images such as video frequency cameras with the behavior to aquatic organism.

Up to the present, in filtering factory etc., a kind of equipment-wherein cultured in water tank aquatic organism of being observed (for example fish) is provided, and this water tank receives natural water constantly and take its image so that captured image is analyzed by television eye or the like, with grasp according to the position of moving about of the fish of being observed fish behavior, and when the abnormal behavior of fish, give the alarm.For example, the position of the fish of observing in order to detect, the image of taking with the given time interval is stored in the video memory, and discern the image area corresponding with the fish of being observed by forming two difference images between the adjacent image, and detect position and the gait of march of the fish of being observed according to the variation of the centre of gravity place of identical image area, thereby detected position and gait of march and under normal condition in advance the velocity distribution of storage compare, to detect unusual (Jap.P. discloses 6-68489 number) of water quality.

But above-mentioned prior art equipment has a problem, promptly since relatively be in the video memory all fixedly pixel carry out, its quantity of information is too big, thereby need the very long processing time, and when the image beyond the water tank enters into the coverage of TV camera, the part that does not need to compare has also been carried out unnecessary comparison, and this makes and is difficult to detect accurately.Therefore, needed is to make water tank obtain taking under the corresponding to state of the coverage of whole water tank and television eye, so that visual corresponding with water tank all the time of all pixels in the video memory.Yet, in the case, run into the difficulty that the position of TV camera is difficult to select again.

In addition, because the purpose of above-mentioned prior art is that the gait of march that will compare the fish of being observed is compared with the velocity distribution that obtains under normal condition, though when fish presents typical abnormal behaviour, can detect, if but behavior of fish and abnormal behaviour are close, if for example fish is risen so that feed, then mistake will occur, thereby be difficult to only compare and the abnormal behaviour when water quality is unusual, taked exactly by velocity distribution with normal condition to unusual judgement.

Therefore, the present invention for eliminate prior art equipment intrinsic the problems referred to above and developing, and the purpose of this invention is to provide the water quality monitoring equipment that utilizes aquatic organism, this equipment can set a monitoring section on the TV screen with on the corresponding optional position, the position of water tank, to realize accurately and rapidly image processing, even and aquatic organism take under the water quality abnormality, to be taked the various actions mode time also can detect the unusual of water quality reliably, thereby avoided makeing mistakes.

According to the present invention, a kind of water quality monitoring equipment comprises: monitoring water tank is used to hold natural water and is further used for culturing aquatic organism; Monitor gamma camera, be used for the aquatic organism of shooting and monitoring water tank; Monitoring television is used to show by the captured image of monitoring gamma camera; The point setting device, be used for setting a plurality of detector points at the image that is presented at the monitoring water tank on the monitoring television, pick-up unit, whether the intensity level that is used to discern the position of each detector points and is used to detect each detector points has the motion owing to aquatic organism to change in the given time interval, and is used for the output position data corresponding with the position of this detector points when detecting intensity level and change; Abnormal behaviour mode pick-up unit is used for monitoring the behavior of aquatic organism at the monitoring time of setting according to the position data of exporting from pick-up unit, and is used for judging whether the behavior of taking at this monitoring time is the abnormal behaviour mode; And alarm device is used for giving the alarm according to the result of determination of abnormal behaviour mode pick-up unit.

This abnormal behaviour mode pick-up unit relatively receives the position data from pick-up unit output, and carries out a kind of operation in the following operation according to this position data: the first monitoring operation is used to the first abnormal behaviour mode that detects (for example mad behavior of moving about); The second monitoring operation is used to detect the second abnormal behaviour mode (behavior that for example protrudes upward); The 3rd monitoring operation is used to detect the 3rd abnormal behaviour mode (behavior of for example escaping); And the 4th monitoring operation is used to the 4th abnormal behaviour mode that detects (for example such as the behavior state of death unusual).In addition, in order to carry out first to fourth abnormal behaviour mode, abnormal behaviour mode pick-up unit carries out all operations of first to fourth monitoring operation, and sends an alarm when monitoring operation detection to the abnormal behaviour mode.

In the first monitoring operation, according to calculating the move distance of aquatic organism in monitoring time from the position data of pick-up unit output, and when the move distance that calculates surpassed set apart from the time, make the judgement that is in the abnormal behaviour mode, do not have unusual judgement otherwise just make.If monitoring time and setpoint distance are suitable, just can detect the abnormal behaviour mode, for example aquatic organism in the short time up and down with along the madness that left and right directions the moves about behavior of moving about.

In the second monitoring operation, set as ground floor in the image of monitoring water tank that a layer with given depth-it extends under the water surface and along horizontal direction, and within the ground floor and outside set a plurality of detector points.This ground floor is used as the reference position, and the end that is used for test example such as aquatic organism appears at the behavior that protrudes upward on the water surface.Calculate, to count output number as the first output number of times in the position data of the detector points in ground floor within the monitoring time, and export number of times as second and further count the output number of representing the position data of the detector points in the part beyond the ground floor in the monitoring time, and when the second output number of times has surpassed one second setting value, make and do not have unusual judgement, and, make the judgement of abnormal behaviour mode when the first output number of times has surpassed first setting value and the second output number of times when being lower than second setting value.If the monitoring time and first and second setting values are suitable, just can detect the abnormal behaviour mode that aquatic organism protrudes upward behavior.

In the 3rd monitoring operation, as the second layer, set that a layer with given thickness-it is present in the image of monitoring water tank and extends along the longitudinal near drain outlet or pump mouth, and within the second layer and outside set a plurality of detector points.The second layer is used as the reference position, near the escape behavior of escaping freeing port with test example such as aquatic organism.Carried out calculating to count the output number of the position data of the detector points in the second layer in the expression monitoring time as the 3rd output number of times, and count the output number of the position data of represent detector points in the second layer part in addition as the 4th output number of times, and when the 4th output number of times has surpassed one the 4th setting value, make and do not have unusual judgement, and surpassed one the 3rd setting value and the 4th output number of times when being lower than the 4th setting value when the 3rd output number of times, make the abnormal behaviour mode and judge.If the monitoring time and third and fourth setting value are suitable, just can detect abnormal behaviour mode such as the escape mode of aquatic organism.

In the 4th monitoring operation, carried out calculating output number of times, and carried out being used for the calculating of the movement velocity of aquatic organism with position data in the counting monitoring time.When output number of times when having surpassed a setting value (set point number), perhaps when movement velocity has surpassed a setting value (setting speed), make and do not have unusual judgement.On the other hand, be lower than setting value and movement velocity is lower than under the situation of setting value, make the judgement that the motion of aquatic organism stops, thereby make the judgement of abnormal behaviour mode at the output number of times.If monitoring time and setting value are suitable, just can detect the abnormal behaviour mode of the death or the like of aquatic organism.

Monitoring water tank can also be divided into a plurality of monitorings part-its each and all be used to culture aquatic organism.In the case, the point setting device is set a plurality of detector points in each monitoring part, and pick-up unit checks in each monitoring part whether the intensity level of each detector points changes in the given time interval, and when detect the variation of intensity level the corresponding position data in position of output and this detector points.The behavior that abnormal behaviour mode monitoring device monitoring aquatic organism is located in each monitoring part, and judging that aquatic organism just gives the alarm by alarm device when all taking the abnormal behaviour mode in all monitoring parts.Even in one of monitoring part the abnormal behaviour mode has taken place, take under the situation of normal behaviour in other monitoring parts aquatic organism, make this situation of such judgement-be and be owing to live in the problem (for example owing to disease or the like) of the aquatic organism itself in the monitoring part that is in abnormality detection rather than owing to the reason of water quality.By this structure, can obtain more sure and water quality monitoring accurately.

Referring now to accompanying drawing,, below embodiment of the present invention will be described.In Fig. 1, monitoring water tank of label 1 expression, it has transparent panel at least on its front surface, and also constantly this natural water is discharged to keep constant water level from a drainpipe 3 by the natural water that feed pipe 2 receptions are fetched from river, pond or the like.The inside of water tank 1 is separated out by three current with holes or straight plate 4a to 4c, and plate 4a to 4c each all have seam (through hole) S (seeing Fig. 2 A to 2C)-these seams and do not allow observed fish to pass through.Natural water produces from feed pipe 2 and flows to the current of drainpipe 3 by the seam S of water stream board 4a to 4c with holes, and width of each seam S is approximately 1mm.In by the separated case part of water stream board 4a to 4c institute, two casees in the centre partly are used as the first and second monitoring part 5a, 5b, and have respectively cultured a fish F or a F ' (for example Medaka flying fish (killifish), carp, crucian) as observed aquatic organism in the first and second monitoring part 5a, 5b.In addition, between the lower surface of the end portion of water stream board 4b, 4c and water tank 1, define that the gap that size is approximately 1mm-it is used to be sent to drainpipe 3 one sides being included in sand in the natural water or the like.In addition, on a part of the water supply opening of feed pipe 2, be provided with a natural water receiving unit 4a '-its seam not, stopping bubble from feed pipe 2, dust etc., thereby stop them to be introduced among monitoring part 5a, the 5b at water stream board 4a.As shown in Figure 3, above-mentioned natural water is at first by a feed pipe 6, and by a filtering layer 7 and after having removed dust, flows through connecting pipe 6 ' and water receiving magazine 8, to be introduced in the monitoring case 1 through above-mentioned feed pipe 2 by pump P etc.Again further, in water receiving magazine 8, the bait feeding mechanism 9 that is used to provide bait has been installed, has been had well heater 10 and a scavenger pump 11 that the temperature that makes natural water keeps the stationary temperature regulating device.

In addition, in Fig. 1, label 12 expression industry monitoring TV camera (monitoring gamma camera) are such as the ITV on the front surface side that is positioned at monitoring water tank 1, with shooting and monitoring part 5a, 5b.In addition, label 13 expression fish pick-up units (pick-up unit), it for example shows the image of monitoring part 5a, 5b on the TV screen 14a of as shown in Figure 1 monitoring television 14, and exports the scope of the monitored area E that sets by light pen (some setting device) LP in each of observed fish F, F ' in succession and monitor position data among part 5a, the 5b.Above-mentioned monitored area E be form by this way-set a plurality of detector points SP1, SP2, SP1 ', SP2 ' in the visual scope of be light pen LP on being presented at monitoring screen 14a monitoring part 5a, 5b, and fish pick-up unit 13 changes according to the intensity level of the detector points among the E of monitored area and detects observed fish F, the movement position of F '.

In addition, label 15 has been represented people's computing machine one by one, it receives the position data from fish pick-up unit 13, detecting observed fish F, the behavior of F ' according to this position data and according to as shown in figure 11 handling procedure, and unusual alarm takes place to send expression water quality in warning horn 36 of operation when detecting behavior unusual.

When water quality takes place when unusual, observed fish F or F ' in monitoring part 5a or 5b take three kinds of abnormal behaviour modes: the madness behavior (the first abnormal behaviour mode shown in Fig. 4 A) of moving about, promptly fish at water tank 5a or 5b to move about unusually up and down at a high speed; Protrude upward behavior (the second abnormal behaviour mode that shows among Fig. 4 B), promptly its moving about by this way near water surface-be that its mouth stretches out water or passes in and out on the water surface; And, escape behavior (the 3rd abnormal behaviour mode that shows among Fig. 4 C), be it near the place of the freeing port of drainpipe 3 sides (promptly under the situation of the first monitoring part 5a near the water stream board 4b, and be near the water stream board 4c under the situation of the second monitoring part 5b) wander up and down, to seek to hide danger.In addition, fish is taked further abnormal behaviour mode, four kinds of behaviors altogether, that is: and under the situation of death, fish presents active state unusual (the 4th abnormal behaviour mode shown in Fig. 4 D)-be, and it swims on the water surface and is in the state that turns on its belly.Sometimes, fish is taked a kind of behavior (seeing Fig. 4 E) under normal condition, and wherein it moves about to its underpart in the scope of the middle body of water tank 5a or 5b with lower constant speed.

Secondly, referring to Fig. 5, the concrete setting of fish pick-up unit 13 will be described below.Video input terminal of label 16 expressions, it receives the vision signal from above-mentioned gamma camera 12; And clamp circuit of label 17 expression, it is used for this vision signal is carried out the square-topped pulse clamp, so that voltage keeps is constant, thereby its sinking level is not changed along with the variation of image and is used to export a luminance signal.Further, horizontal synchronization separation circuit of label 18 expressions is used for isolating a horizontal-drive signal from this vision signal; Vertical address counter of label 19 expressions is used for according to horizontal-drive signal a picture (field) being divided into 52 row along the longitudinal; And horizontal address oscillator of label 20 expressions is used for a horizontal line of a picture is divided into 64 points.These devices have been set detector points (3328 points altogether): 64 points are arranged and along vertical direction 52 (see figure 6)s are arranged along horizontal direction in a picture, and these modes with the address of RAM23 obtain distributing, and all detector points positions all are stored among this RAM23.The number of detector points is not limited only to this value, and can adopt the detector points of different numbers, for example, can adopt more detector points.

In addition, latch cicuit of label 21 expressions, it is received in the position data (address date) of each detector points that produces in vertical address counter 19 and the horizontal address oscillator 20 at each.Latch cicuit 21 is according to latch a latch signal (latch pulse) sequential circuit 32, that produced by an alarm signal that will be described below from an alarm, keep the position data (about the position data of the detector points of generation intensity level variation) of obtained related detection device point when this alarm signal occurs, and further the position data that is kept is delivered to a microcomputer 33.In addition, 60 A/D converters of label 22 expressions, it converts luminance signal to digital signal, go on foot or level to be divided into 64 in variable density, and this A/D conversion all is sent to ROM24 and RAM23 in the digital signal that each point is produced.

In addition, label 23 expressions are used to store the above-mentioned RAM of above-mentioned digital signal.RAM23 thinks that the mode of sampled data stores and a corresponding numerical data in field of input in succession, and the once new and old sampled data in per three fields and it is delivered to above-mentioned ROM 4.This compare operation also can be carried out at interval with different fields.In addition, label 24 expressions have wherein preestablished the ROM of intensity level baseline encoded shown in Figure 7.This ROM24 receives new sampled data and receives old sampled data from RAM23 from A/D converter 22.ROM24 compares new sampled data and old sampled data, so that whether variable density (intensity level variation) has taken place on a detector points according to the baseline encoded inspection.In fact, when observed fish F or F ' do not exist, near the old sampled data arrival white level of detector points (A), thereby and when observed fish movement near the new sampled data at the detector points place of correspondence changes to black level when (C), the variable density that is positioned at the some h within the sensing range is judged, comprised an alarm signal (8 output datas) of the position signalling on the detector points with output.On the other hand, if observed fish F or F ' existence, in this detector points, old sampled data reaches near black level (D), and after same fish movement, the new sampled data of same point move on to white level near (B), and thereby a some i in non-sensing range be used as benchmark.In the case, the output of alarm signal can not occur.Therefore, when the variable density of the direction that takes place at the detector points place to advance along fish F or F ', alarm signal occurs, thus can be basically the observed fish F of continuous detecting, the movement position of F ' in real time.Much less, do not have therein in the zone of fish F or F ', old and new sampled data all is near the white level, and a some i within non-sensing range is used as benchmark.Further, under observed therein fish F, the situation of F ' stop motion, old and new sampled data all be in black level near, and a some k within the non-sensing range is used as benchmark.Therefore, in both cases, all make the judgement that does not have variable density, thereby do not produce alarm signal output.

Further, multichannel modulation selective circuit of label 25 expressions, it is selected from the alarm signal of ROM24 input according to the sensitivity of setting in a detector sensitivity switch 26, and only exports alarm signal according to the sensitivity of setting.Detector sensitivity switch 26 can be set alarm signal sensitivity in 8 grades mode, thereby can ignore insecure variable density and only detect real variable density.One of label 27 expression detect RAM, and it is stored once from the alarm signal of selecting circuit 25 and with its address and writes a sign RAM28, and further it is outputed to a "AND" circuit 29.

In addition, light pen control circuit of label 30 expressions, it is used for by described light pen LP sign RAM28 being delivered in a mark position (positions of detector points SP1, SP2 and other detector points) of setting on television image.Light pen LP is detected electrons light when contacting with the monitor picture, and detection signal reaches processing level and obtained by light pen control circuit 30 subsequently by the amplifier processing of light pen LP.The mark position that light pen LP sets is passed through in sign RAM28 storage, and it is outputed to "AND" circuit 29.Light pen LP allows to set a monitored area E on monitoring television 14, for example as shown in fig. 1.Further, monitoring water tank 1 on whole TV screen 14a the time, can also be set all 3328 detector points by imaging shown in Figure 10 B therein, and with whole TV screen 14a as monitored area E.

In addition, the above-mentioned "AND" circuit of label 29 expressions, be used for responding because the position that overlaps with the mark position that is stored in sign RAM28 and, this alarm signal delivered to one indicate that combiner circuit 31 and an alarm latch sequential circuit 32 reception from the alarm signal that detects RAM27.That is, have only when owing to be stored in a position that the address location of sign among the RAM28 overlap when receiving alarm signal, its just obtains as alarm signal exporting at last.The mark position that sign combiner circuit 31 will be represented with alarm signal, with the state of television scanning synchronised under, be added on the vision signal of video input terminal 16 inputs, and the signal that is produced outputed to a video output terminal 37.Therefore, shown in Fig. 1 or Figure 10 B, the detector points that variable density changes is inverted to piece on display.

Further, sequential circuit is latched in the above-mentioned alarm of label 32 expression, and it sends a latch signal at the input timing of alarm signal and gives latch cicuit 21, and is retained to the position data (address date among the RAM23) in the moment of the input of latch cicuit 21.The above-mentioned microcomputer of label 33 expressions, it is when receive to keep and send into and during from the address date of latch cicuit 21, outputing to above-mentioned personal computer 15 as this address date transformation parallel data of position data and with data converted by a RS-232C outlet terminal 34.This parallel data has represented to take place the some position of the detector points of the some position that luminance signal changes in the mode of numeric data.For example, under the situation of Fig. 1, at the first and second monitoring part 5a, 5b, the detector points that variable density has taken place on picture has obtained actual demonstration by the X-Y coordinate, thus make the SP3 point be denoted as (X, Y)=(8,20) and SP3 ' be denoted as (X, Y)=(30,25).In demonstration, label 35 expression is used for a RAM control circuit that RAM23,27,28 is controlled, and the warning horn be made up of a hummer, a warning light or the like of label 36 expressions.

In addition, referring to Fig. 8 and 9, will the function setting of the central control section 38 of personal computer 15 be described.Fig. 8 is a block diagram, has shown the above-mentioned control section 38 that has the function implement device.In this displayed map, data receiving trap of label 39 expression-be used to receive the position data of import in succession from above-mentioned outlet terminal 34, and decision maker of label 40 expressions-it receives from this position data of receiving trap 39 with according to judging that about the parameter (it will be described later) of monitored area E these data are position datas of the first monitoring part 5a or from second position data of monitoring part 5b.When the data that receive are the data of the first monitoring part 5a, decision maker 40 is delivered to one first test section 41a with this position data, if and the data that receive are the data on the second monitoring part 5b, it delivers to one second test section 41b with position data.

Further, label 41 expression abnormal behaviour mode pick-up units, whether it analyzes observed fish F in the first monitoring part 5a or the second monitoring part 5b or the behavior of F ' according to this result of determination, unusual to check behavior mode.Abnormal behaviour mode pick-up unit 41 comprises: the first test section 41a is used for analyzing according to the position data on the first monitoring part 5a behavior of fish F; And the second test section 41b is used for the behavior that the position data of basis on the second monitoring part 5b detects fish F '.At first have substantially the same function and constitute by as shown in Figure 9 function implement device with the second test section 41a, 41b.Each test section 41a, 41b according to predetermined handling procedure (seeing Figure 12 to 15), according to the various parameters of setting in the input media 42 of personal computer 15, judge the abnormal behaviour mode.When detecting observed fish F the abnormal behaviour mode is arranged, test section 41a will comprise that during detecting the abnormal behaviour mode the first detection signal a of a signal that shows the abnormal behaviour mode delivers to next alarm command device 44 constantly.On the other hand, when detecting the abnormal behaviour mode of observed fish F ', test section 41b delivers to same alarm command device 44 to one second detection signal b in an identical manner, and wherein this second detection signal b comprises a signal that shows this abnormal behaviour mode.In addition, relevant detection part 41a, 41b deliver to display control unit 46 to an idsplay order signal, and wherein this idsplay order signal list is understood the present monitoring state and the kind of abnormal behaviour mode.

Further, the above-mentioned input media of label 42 expressions, this device is used for being received in the required various parameters of analysis of above-mentioned abnormal behaviour mode pick-up unit 41; And label 43 expression parameter setting apparatus, be used to store imported various parameters and be used for this supplemental characteristic is sent to abnormal behaviour mode pick-up unit 41 and display control unit 46.Further, label 44 expression alarm command devices, it receives first or second detection signal from abnormal behaviour mode pick-up unit 41, and just think when the first and second test section 41a, 41b both receive first and second detection signals of expression abnormal behaviour mode, when just thinking promptly that observed fish F in the first monitoring part 5a and the second monitoring part 5b and F ' take the abnormal behaviour mode (P6 among Figure 11, P7), just send an alarm command signal.Therefore, even for example the observed fish F in a monitoring part 5a presents normal condition and when having only second detection signal simultaneously and being input to wherein, does not export the alarm command signal.

In addition, label 45 expression alert driver devices, its response is delivered to display control unit 46 with a red light output signal and a hummer output signal, and further an alert driver signal is delivered to warning horn 36 from the alarm command signal of alarm command device 44.Label 46 expression display control units, its receives from the various idsplay order signals of relevant detection part 41a, 41b with from above-mentioned lamp output signal and other signals of alert driver device 45, to show various images on monitoring television 14 according to these idsplay orders.

To be described in the operation of setting the required various parameters of abnormal behaviour mode detecting operation in the personal computer 15 below.Suppose that monitoring water tank 1 taken by TV camera 12 as illustrated in fig. 1, and monitoring water tank 1 shown in Figure 10 B by imaging on TV screen 14a.Under this state, monitoring section R sets on TV screen 14a by light pen LP.In this embodiment, for the simplification of describing, monitoring water tank 1 shown in Figure 10 B by imaging on whole TV screen 14a, and all detector points (1 to 3328 point) all are set to monitored area E.In the case, can also be as previously mentioned with monitoring water tank 1 imaging (see figure 1) and set visual corresponding detectors point with monitoring water tank 1 on the part of monitoring screen 14a.

At first, by input media 42 inputs " about the parameter of monitored area E ", thereby make personal computer 15 can discern the monitored area E that sets by light pen LP.Shown in Figure 10 A, personal computer 15 is set and two the corresponding first monitoring part 5a ' of monitoring part 5a, 5b and the second monitoring part 5b ', and be set under the condition of initial point (0,0) these two monitorings of identification parts on the X-Y coordinate at the upper left quarter of the first monitoring part 5a '.More particularly, this identification can be carried out by this way, promptly the first monitoring part 5a ' covers point 0 to 31 along X-direction, and covers point 0 to 52 along Y direction, and the second monitoring part 5b ' covers point 32 to 64 and covers point 0 to 52 along Y direction along X-direction.

In addition, identification can be carried out by this way, and each all is divided into four districts along X-direction promptly to monitor part 5a ', 5b ', and promptly first to fourth layer, and be divided into four districts, i.e. A to D layer along Y direction.In the case, as parameter imported with following coordinate corresponding position (X, Y): the coordinate C1 that has represented the height of the water surface among monitoring part 5a ', the 5b '; The zone of A layer (ground floor) is along the coordinate C2 of the lower position of horizontal direction near the expression water surface; And, near water stream board 4b, 4c on the draining oral-lateral of each monitoring part 5a, 5b, set the coordinate C3 of the width of the 4th layer (second layer) in a longitudinal direction.In this embodiment, coordinate C1 is set to initial point (0,0), coordinate C2 is set to (0 under the situation of the first monitoring part 5a ', 13) and under the situation of the second monitoring part 5b ' be set to (32,13), and coordinate C3 is set to (24 for the first monitoring part 5a ', 52) and for the second monitoring part 5b ' be set to (56,52).Therefore, abnormal behaviour mode pick-up unit 41 can be discerned the A layer of each water tank and the 4th layer position.A layer and the 4th layer protrude upward in detection under the situation of behavior and escape behavior, are used as the reference position when the position of observed fish F of identification or F '.Naturally, can set relevant parameters accordingly arbitrarily with the image of the monitoring water tank 1 of imaging on monitoring screen 14a.

Secondly, by input media 42 inputs observed " the abnormal behaviour detected parameters " of abnormal behaviour mode of fish, wherein these abnormal behaviours be madness move about behavior, to protrude upward behavior, escape behavior and active state unusual.At first, for the madness behavior of moving about, a madness move about commencing speed, monitoring time and have been set as this parameter by count out (move distance) (seeing Fig. 9 and 12).In these parameters, the madness commencing speed of moving about has shown the speed of moving about of observed fish F or F ', and when surpassing this speed, make the judgement that the madness behavior of moving about begins, send the instruction (P11 of Figure 12, P12) of demonstration " the madness behavior of moving about confirms " thus, thereby make operation enter monitoring state (P13).The speed of observed fish, by the first pick-up unit 41a or the second pick-up unit 41b, according to formula (speed)=(along X-direction pass through count out+along Y direction pass through count out)/required time (second) of motion, and as the function of the number of the observed point that fish passed through of position data and same monitoring case, and calculated.Monitoring time is in the time that has confirmed that the mad behavior of moving about begins continuous monitoring afterwards, and by counting out corresponding to the move distance of observed fish.When the move distance in this monitoring time of the fish of being observed reaches above-mentioned counting, make the move about judgement (P14 to P16) of behavior of madness, if and the move distance of the fish of being observed in monitoring time is when being lower than this and counting, make not judgement that the mad behavior of moving about takes place (P14, P20).In this embodiment, as an example, the madness commencing speed of moving about is set to 100 points (P)/second, and monitoring time was set to 10 seconds, and was set to 200 points by count out (move distance).

Protruding upward under the situation of behavior, as parameter setting the number of times (frequency) that exists of continuous A layer, the number of times that exists, monitoring time and to the number of times (seeing Fig. 9 and 13) of the motion of different location.In these parameters, the continued presence of A layer has shown that the fish of being observed continues to be in the number of times in the above-mentioned A layer scope.If surpass this value, then judge to have begun to protrude upward behavior, thereby send the instruction (P31 among Figure 13,32) that demonstration " protrudes upward the behavior confirmation ", thereby make operation enter monitoring state (P33).After the beginning that has confirmed the behavior that protrudes upward, monitoring time is identical with the time of continuous monitoring.Further, the number of times of existence is that the fish observed is in the number of times in the A layer in monitoring time.After past, judge whether this number of times surpasses this value at this monitoring time.If surpassed this value, make the judgement of the behavior of protruding upward, and show " protruding upward behavior " (P34, P39 to P42).The frequency table of continued presence understands that the position data in the A layer is input to the number of times of the first or second pick-up unit 41a or 41b continuously, if and for example observed fish F, F ' be in the A layer in the given time, just be imported into wherein about the position data of this fish.The number of times that moves to the different location is the number of times of fish movement to A layer part in addition.When in monitoring time, surpassing the value of a setting, make the judgement (P36, P37, P38) that does not have the behavior of protruding upward.The number of times that stops also can to obtain detecting by the position data beyond the position data in the counting A layer.If any position of the fish of being observed beyond the A layer stopped the given time, this position data is just imported wherein continuously.In this embodiment, as an example, the number of times of the continued presence in the A layer is set to 3, and monitoring time is got 2 minutes, and the number of times that moves to the different location is taken as 3.

Under the situation of escape behavior, as parameter setting the number of times of the number of times of continued presence, existence in the 4th layer, monitoring time and move to different local number of times (seeing Fig. 9 and 14).In these parameters, the frequency table of continued presence understands that the fish observed is in the number of times in the 4th layer the scope in the 4th layer, if and surpassed this value, just make the judgement that escape behavior begins, thereby show that " confirmation escape behavior " and the fish of being observed are in monitoring state (P51 of Figure 14, P52, P53).Monitoring time is the monitoring time after the beginning that has confirmed escape behavior, and to have number of times be the number of times that the fish observed exists in this monitoring time.After past, make the judgement whether this value has surpassed setting value at this monitoring time.If surpassed setting value, make escape behavior has taken place, thereby demonstrate " escaping unusual " (P54, P59 to P62).Under the situation of the behavior of protruding upward, the position data within the frequency table of continued presence is understood the 4th layer is imported this true number of times among the first or second pick-up unit 41a or the 41b continuously, and counts the number of times of existence according to this position data.The number of times that moves to the different location be the fish observed move on to or be in the 4th layer beyond the number of times of different piece.When in monitoring time, having surpassed a setting value, just make and do not escape unusual judgement (P54, P55 to P57).In this embodiment, as an example, the number of times of continued presence is taken as 3 in the 4th layer, and the number of times of existence is taken as 3, and monitoring time is set to 2 minutes, and the number of times that moves to the different location is set to 3.

Under the unusual situation of active state, as parameter setting continuous stand-by time, monitoring time, signal input number and movement velocity (seeing Fig. 9 and 15).Continuously stand-by time is the time that the fish observed rests on given place continuously, and promptly luminance signal changes and stops and not from time of the input signal of fish pick-up unit 13.If this state has surpassed a setting value, just make the judgement that activity stops, thereby demonstrate " activity stops ", so that operation enters monitoring state (P71 to P73 among Figure 15).Monitoring time is the time of monitoring after having confirmed movable stopping, and the number that signal is imported is corresponding to the number of times that has produced from the input signal of fish pick-up unit 13, and movement velocity is the move about speed of fish under monitoring state of being observed.Outnumbered a setting value or movement velocity in signal input become and are higher than under the situation of a setting value in the monitoring time, and just making does not have unusual judgement, thereby make the demonstration disappearance (P74 to P78) of expression " activity stops ".On the other hand, when the number of signal input therein and movement velocity all are lower than setting value, make the unusual judgement of active state (P79).In this embodiment, as an example, continuously stand-by time is set to 30 seconds, monitoring time and was set to 3 minutes, the number of signal input be set to 5 and movement velocity be set to for 5 point/seconds.In addition, the parameter value of setting is not limited only to above-mentioned description, but is suitably set under the situation of natural characteristic of the fish that can observe considering or the like.

Therefore, the relevant parameter of setting by input media 42 is sent to the first and second pick-up unit 41a, 41b (P1 among Figure 11) by parameter setting apparatus 43, and when the parameter idsplay order that receives from input media 42, parameter setting apparatus 43 is presented at these parameters on the monitoring television 14 by display control unit 46.

The operation of wherein having set this equipment of parameter as described above is described below.The vision signal of importing by video input terminal 16 after the shooting of monitoring water tank is carried out the square-topped pulse clamp by clamp circuit 17, and the luminance signal of each is all changed digital signal in A/D converter 22.In addition, address counter 19 and address oscillator 20 are set 3328 detector points-these detector points have been obtained distribution simultaneously in the mode of the address of RAM23, and the address of the detector points of each is sent to latch cicuit 21 all the time on a picture.

The sampled data of a field of sampling is also one after the other delivered to ROM24 and RAM23 in the A/D converter 22, and ROM24 compares the new sampled data from A/D converter 22 inputs according to intensity level baseline encoded (see figure 7) with the old sampled data of importing from RAM23.In the case, do not exist therein in the zone of observed fish F or F ', between new and old sampled data, do not have intensity level to change and take place, thereby made the judgement that does not have variable density.Therefore, in the case, there is not alarm signal output.On the other hand, at observed fish F or F ' moves about and striden across simultaneously under the situation of the detector points among monitoring part 5a or the 5b, because observed fish F or F ' striden across a detector points, change so can detect the intensity level of same point, thereby the some h alarm signal in the sensing range of basis of reference coding is output to multichannel modulation selective circuit 25.Therefore, if observed two fish F, F ' do not move, the motion that the compare operation of a field produces owing to the observed fish F in the first monitoring part 5a produces alarm signal also owing to the motion of the observed fish F ' in the second monitoring part 5b produces alarm signal.

In multichannel modulation selective circuit 25, judge whether above-mentioned alarm signal is consistent with the sensitivity of setting in the detector sensitivity switch 26.If consistent with this sensitivity, then above-mentioned alarm signal is sent to and detects RAM27.Detecting RAM27 is stored in this alarm signal corresponding address location and further it is outputed to "AND" circuit 29.On the other hand, above-mentioned sign RAM28 stores the position of these detector points (promptly all in this embodiment detector points) that write by light pen LP, and this position signalling is output to "AND" circuit 29.When receiving when detecting the alarm signal of RAM27, the position that "AND" circuit 29 detects these detector points whether with position consistency from the detector points of sign RAM28 input, and further sign combiner circuit 31 is delivered in this alarm signal and sequential circuit 32 is latched in alarm.Sign combiner circuit 31 is according to the input of above-mentioned alarm signal, will be added on the vision signal with the synchronous marking signal of television scanning.Therefore, on TV screen 14a, the position (in the case, detector points SP6, SP6 ' in the position that has observed fish F, F ' are shown in Figure 10 B) that the detector points of variable density taken place thereon is by paraphase precedent such as black and obtain showing.Correspondingly, the observed fish F that is moving, the position of F ', the paraphase by detector points always obtains showing.

In addition, the input of sequential circuit 32 according to above-mentioned alarm signal latched in alarm, and a latch signal is delivered to latch cicuit 21.In response to the input of this latch signal, latch cicuit 21 keeps the corresponding address date of variable density when alarm signal occurring, i.e. the address date of SP6 and SP6 ', and further these data are delivered to microcomputer 33.In microcomputer 33, address date is changed parallel data (position data on the X-Y coordinate) and is output to RS-232C outlet terminal 34 subsequently.

Observed therein fish F, F ' in monitoring water tank 5a, 5b, move about and the situation of moving under, above-mentioned position data is outputed to personal computer 15 continuously from outlet terminal 34, and this position data is input to the data sink 39 of personal computer 15 in succession.Data sink 39 is delivered to decision maker 40 with the position data of input, and decision maker 40 checks that according to the position data of input this position is among the first monitoring part 5a or being in second monitors among the part 5b.In addition, according to result of determination, if the position data on the first monitoring part 5a then it delivers to the first test section 41a in succession to this position data, and if the position data on the second monitoring part 5b then it delivers to the second test section 41b (P1 to P3 among Figure 11) in succession to this position data.Further, decision maker 41a, 41b detect respectively whether the abnormal behaviour mode has taken place in the first and second monitoring part 5a, 5b: madness move about behavior, to protrude upward behavior, escape behavior and active state unusual.The first and second test section 41a, 41b judge the abnormal behaviour mode of observed fish F, F ' according to following program.Because the first and second test section 41a, 41b carry out identical monitoring operation, for convenience, the monitoring of two test section 41a, 41b operation is to carry out respectively according to the position data of importing in this description.

I) madness move about behavior detection (the first monitoring operation, see Fig. 9,12 and 4A)

According to the parameter of setting, the speed detector 47 of the first or second pick-up unit 41a or 41b checks whether the speed of observed fish F or F ' has surpassed the madness commencing speed (100P/S) of moving about.If the speed of observed fish has surpassed 100P/S (P11 of Figure 12), the judgement that begins according to the behavior of moving about to madness, speed detector 47 sends the instruction that is used for showing " the madness behavior of moving about confirms " to display control unit 46, thereby make system enter madness move about the behavior monitoring state (P12, P13).According to above-mentioned idsplay order, display control unit 46 shows " the madness behavior of moving about confirms " on TV screen 14a.After monitoring beginning, madness behavior decision maker 49 that moves about, according to the detection of move distance pick-up unit 48, check a monitoring time (10 seconds) lining pass through to count out whether surpassed 200P (P14, P15).If in monitoring time, should surpass 200P by counting out, then judge the madness behavior of moving about that taken place, thereby first test section 41a one first detection signal of the mad behavior of moving about of expression is delivered to alarm command device 44, the second pick-up unit 41b delivers to alarm command device 44 (P16, P17) to one second detection signal of the mad behavior of moving about of expression simultaneously.Further, an idsplay order that is used for " madness is moved about unusually " is sent to display control unit 46 (P18), thereby " madness is moved about unusually " (seeing Figure 10 B) occur on TV screen 14a.This detection signal transmit operation and idsplay order operate in owing to continue to carry out between the detection period of the abnormal behaviour mode of the mad behavior of moving about.Even after monitoring time, also be no more than under the situation of 200P by counting out, judge not unusual (P20), be used for the instruction (P21) that cancellation " the madness behavior of moving about confirms " shows thereby send, upward disappear thereby make " the madness behavior of moving about confirms " be presented at TV screen 14a.

Ii) protrude upward behavior detection (the second monitoring operation, see Fig. 9,13 and 4B)

According to the parameter of setting, there are frequency detecting device 50 detections in a continuous A layer or check whether observed fish F or the number of times of F ' continued presence in the A layer have surpassed 3 (P31 among Figure 13).If this detection shows that this frequency has surpassed 3, then begin the judgement of the behavior that protrudes upward, thereby send the instruction that demonstrations " protrudes upward the behavior confirmation " to display control unit 46 as fish, thereby enter the behavior monitoring state that protrudes upward (P32, P33).According to this idsplay order, display control unit 46 shows " behavior that protrudes upward confirms " on TV screen 14a.After monitoring operation beginning, the A layer exists frequency detecting device 51 counting fishes to be present in number of times in the A layer in monitoring time, and move on to the number of times (P34 that frequency detecting device 52 counting fishes in different location are present in A layer place in addition, P35, P36), if and the number of times that was present in the place beyond the A layer in 2 minutes has surpassed a setting value, one protrude upward behavior decision maker 53 make do not have unusual judgement-even the number of times that is present in the A layer surpassed setting value (3), and further send the instruction (P36 to P38) that elimination " protrudes upward the behavior confirmation " to display control unit 46, thereby the demonstration that makes TV screen 14a go up " behavior that protrudes upward confirms " disappears.The number of times that moves to the different location in monitoring time (2 minutes) lining is lower than under the situation of setting value, after monitoring time is gone over, judge whether the number of times that is present in the A layer has surpassed setting value (3) (P39), if and surpassed this setting value, just make and protrude upward unusual judgement (P40), and this first detection signal that protrudes upward behavior of first test section 41a output expression is to alarm command device 44, and the second test section 41b delivers to same alarm command device 44 (P41) to second detection signal that expression protrudes upward behavior simultaneously.In addition, the idsplay order that is used for " protruding upward unusual " is sent to display control unit 46 (P42), shows thereby " protruding upward unusual " occur on TV screen 14a.Being sent in to protrude upward of detection signal and idsplay order continues between unusual detection period to carry out.If be lower than setting value at the number of times that exists of P39 in the A layer, promptly exist number of times and the number of times that exists in the different location in the A layer all is lower than under the situation of setting value, make and do not have unusual judgement (P39, P37).

Iii) escape behavior detects (Fig. 9,14,4C are seen in the 3rd monitoring operation)

At first, according to the parameter of setting, continuous the 4th layer exists frequency detecting device 54 to check whether the number of times that observed fish F or F ' rest in the 4th layer has continuously surpassed 3 (P51 among Figure 14).If this has outnumbered 3, just make the judgement that escape behavior begins, thereby it sends the instruction (P52) of demonstration " escape behavior confirmation " to display control unit 46, thereby make display control unit 46 on TV screen 14a, show " escape behavior confirmation ", thereby make operation enter escape behavior monitoring state (P53).Beginning in response to this monitoring operation, the 4th layer exists frequency detecting device 55 and moves on to frequency detecting device 56 counting fishes in different location are present in number of times in the 4th layer and this fish place beyond being present in the 4th layer in monitoring time number of times (P55, P56), if and the number of times that is present in the different location in monitoring time has surpassed a setting value (3), even the number of times that then is present in the 4th layer has surpassed a setting value (3), escape behavior decision maker 57 is also made does not have unusual judgement, and (P56 P57) and further sends an instruction (P58) that is used for deletion " escape behavior confirmation " to display control unit 46.Therefore, the demonstration of " the escape behavior confirmation " on TV screen 14a has disappeared.Times of exercise to the different location in monitoring time (2 minutes) is lower than under the situation of setting value (3), and after the past, its judges whether the number of times that exists has surpassed a setting value (3) (P59) in the 4th layer at this monitoring time.If surpassed this setting value, according to judgement to escape behavior, the first test section 41a delivers to alarm command device 44 to one first detection signal of expression escape behavior, and the second test section 41b delivers to same alarm command device 44 (P61) to one second detection signal of expression escape behavior simultaneously.In addition, it sends an instruction (P62) that is used for showing " escaping unusual " to display control unit 46, thereby makes display control unit 46 allow " escaping unusual " to appear on the TV screen 14a.The transmission of detection signal and idsplay order operate between the escape behavior detection period and carry out continuously.If the number of times that exists in the 4th layer at P59 is lower than setting value, promptly be present in the number of times of different location and the number of times that is present in the 4th layer therein and all be lower than under the situation of setting value, just make and do not have unusual judgement (P59, P57).

The iv) detection that active state is unusual (Fig. 9,15,4D are seen in the 4th monitoring operation)

Whether continuous stand-by time of stand-by time pick-up unit 58 detections has surpassed a setting value (30 seconds) (P71 among Figure 15) at first, continuously.If this continuous stand-by time has surpassed this setting value, just make the judgement of the fish stop motion of being observed, and display control unit 46 thereby receive is used for showing the idsplay order (P72) of " activity stops ", thereby makes operation enter active state exception monitoring state (P73).Further, according to this idsplay order, " activity stops " showing on TV screen 14a.Beginning in response to this monitoring operation, active state abnormal detector 61, by signal incoming frequency pick-up unit 59 and movement velocity pick-up unit 60, the number of the detection signal of monitoring time (3 minutes) lining input whether surpassed a setting value (5) and movement velocity whether surpassed a setting value (5P/S) (P75, P76).If any one in these values surpassed setting value in monitoring time, just make and do not have unusual judgement (P77), thereby send the instruction (P78) that deletion " activity stops " showing.Therefore, " activity stops " on TV screen 14a shows disappearance.Even the number and the movement velocity of signal input afterwards still all are lower than under the situation of setting value in the past at monitoring time therein, judge the death (P79) of fish, thereby make the first test section 41a deliver to alarm command device 44 to one first unusual detection signal of expression active state, the second test section 41b delivers to same alarm command device 44 (P80) to one second unusual detection signal of expression active state simultaneously.Further, be used for showing that an instruction of " dead unusual " is sent to display control unit 46 (P81), thereby " dead unusual " shown on TV screen 14a.The transmission of detection signal and idsplay order operate between the unusual detection period of active state and carry out continuously.

On the other hand, under the situation that observed therein fish F or F ' are in normal condition, promptly working as the fish of being observed is in shown in Fig. 4 E when normal, owing to do not take any abnormal behaviour mode, the first or second test section 41a or 41b not to detect the abnormal behaviour mode and not to alarm command device 44 output detection signals.In addition, if observed fish F, F ' demonstrate different abnormal behaviour modes, for example the first test section 41a sends that expression protrudes upward first detection signal of behavior and the second test section 41b produces second detection signal of expression escape behavior.

As mentioned above, as long as in any one in monitoring part 5a, 5b the abnormal behaviour mode has taken place, alarm command device 44 just continues to accept first or second detection signal, and have only when receiving first and second detection signals of expression abnormal behaviour mode simultaneously, when promptly having only observed fish F, F ' in being in the first and second monitoring part 5a, 5b all to take certain abnormal behaviour mode, an alarm command signal just arrives alert driver device 45 (P6 among Figure 11, P7).In other words, when two observed fishes were taked different abnormal behaviour modes, warning horn was also worked.Therefore, when having only a detection signal to be imported in the above-mentioned alarm command device 44 therein, for example, if shown in Fig. 4 F, thereby have only and present the behavior of protruding upward among the first monitoring part 5a and make the first test section 41a import first detection signal, and thereby the observed fish F ' in the second monitoring part 5b is in normal condition and makes the second test section 41b not export second detection signal, does not then export the alarm command signal.Alert driver device 45 comes operational alarm device 36 according to the input of this command signal.The alarm buzzer of formation warning horn 36, warning light or the like are activated, and to send expression the unusual alarm of water quality have taken place.In addition, alert driver device 45 sends a red light output signal, so that display control unit 46 makes a red light on the TV screen 14a light, thereby the unusual warning of water quality has taken place in the expression representative.

Though in the description of this embodiment, in monitoring water tank 1, be provided with two monitoring parts, also two or more monitoring parts can be set therein.In the case, have only when in all monitoring part, all detecting any abnormal behaviour mode, just carry out alert action.Along with the increase of monitoring number partly, the accuracy of abnormality detection is improved.In addition, the simplest structure is that a monitoring part only is set in monitoring water tank 1, and even in this case, also can be according to above-mentioned program, by first to fourth monitoring operation, detect multiple abnormal behaviour mode, and if carry out alert action in response to the detection of any abnormal behaviour mode, more sure and monitoring operation accurately can be obtained than prior art equipment.

As mentioned above, according to this embodiment, owing to can on TV screen 14a, freely set detector points SP1, SP2 etc. accordingly with the image of monitoring water tank 1, so can avoid on the unwanted part of image comparison institute, carrying out the intensity level change-detection, but only on TV screen 14a, carry out the intensity level change-detection in the needed scope, thereby realized accurately and rapidly handling, and can cover the monitoring water tank of different shape and size, and can strengthen the installation degree of freedom of monitoring water tank 1 and video frequency camera 12.In addition, preliminary judgement by the commencing speed of moving about according to such parameter-these parameters such as the madness of the behavior of moving about for madness-carry out, for protruding upward the continued presence number of times in the A layer that behavior detects, the continued presence number of times in the 4th layer that detects for escape behavior and for the continuous stand-by time of action abnormality detection, before the approaching mode of appearance and various abnormal behaviour modes, do not begin the monitoring operation of subregion, even thereby the behavior approaching occurred with the abnormal behaviour mode, more strict monitoring operation subsequently can judge that also it is not the abnormal behaviour mode, thereby can realize more sure and monitoring operation accurately.

In addition, in the monitoring operation of in monitoring time, carrying out, also according to such parameter detect-passing through of detecting of these parameters such as the behavior of moving about for madness count out, the number of times of the motion in the place of detecting for the behavior that protrudes upward to the A layer, the number of times of the motion in the place of detecting for escape behavior beyond the 4th layer and for the signal input number of times and the movement velocity of active state abnormality detection, thereby can consistently set relevant parameters, thereby can under the condition of the characteristic that is suitable for these aquatic organisms most, carry out accurate and sure water quality monitoring operation with the characteristic of the aquatic organism that will culture.Further, thereby owing to can freely set monitoring time can detect the fish of being observed under the state that is limited to the action in the time that sets abnormal behaviour mode, thereby can set monitoring time, thereby can detect the abnormal behaviour mode with higher accuracy according to the characteristic of the fish of being observed.

In addition, for the detection that protrudes upward behavior and escape behavior, near the coordinate of the A layer the water surface and can set arbitrarily matchingly with size and the characteristic of the fish that will monitor etc. near the 4th layer coordinate of water stream board, thus can carry out the operation of water quality monitoring more accurately.In addition, because being the number of times that exists according to number of times that exists in A layer and the 4th layer and the place beyond these layers, the abnormal behaviour mode detects, even for example surpassed setting value at the number of times that in the A layer, exists in the monitoring time, the number of times that exists in the different location also surpasses under the situation of setting value therein, can make it is not to protrude upward behavior but the judgement of the action of feed bait or the like, even, also can avoid wrong detection so the mode approaching occurred with the abnormal behaviour mode.

Moreover, owing to carried out suitable setting with observed the fish F and the F ' of monitoring in the first and second monitoring part 5a, 5b, even for example fish F takes the action approaching with the abnormal behaviour mode owing to sick or the like, under other the normal situation of fish F, judge that water quality does not take place is unusual, thereby can realize not being subjected to that the health status of observed fish influences, water quality monitoring more accurately to operate.In addition, because monitoring water tank 1 separates with water receiving magazine 8, do not need air pump or the like is connected on the monitoring water tank 1, thereby the bubble that this pump produced directly do not enter monitoring water tank 1, this can prevent to make the fault that produces owing to bubble or the like in detection.In addition, owing on the water stream board 4a of monitoring water tank 1, be provided with natural water receiving unit 4a ', can prevent that bubble, dust or the like from entering monitoring part 5a, 5b.In addition, owing between the interior lower surface of the water stream board of monitoring water tank 1 and this water tank 1, define clearance t, can discharge the dust that produces in monitoring water tank 1, floating careless or the like, thereby prevent that dust etc. from resting in the monitoring water tank 1 by this gap portion.

As mentioned above, according to the present invention, owing to can on the monitoring television picture, freely set a plurality of detector points accordingly with the image of monitoring water tank, thereby can only detect the variation of the intensity level in the needed scope on the television image, and do not detect the relatively intensity level variation in the unwanted part of institute of image, thereby can realize accurately and rapidly handling, and operation can be consistent with the monitoring water tank with different shape and size, and can strengthen in the locational degree of freedom of monitoring water tank and TV camera.In addition, detect for the abnormal behaviour mode, judgement is to be undertaken by the various parameters in the monitoring time of the position data of input in succession and setting are compared, thereby monitoring time and each parameter can set according to the characteristic of the aquatic organism that will culture, operates thereby can carry out accurate and safe water quality monitoring under the state of the characteristic that is suitable for aquatic organism most.

In addition, in the second or the 3rd monitoring operation, near the position of the ground floor the water surface or can consistently set with the size of the aquatic organism of being monitored, characteristic or the like in the position of the second layer of draining oral-lateral, this can guarantee the operation of water quality monitoring more accurately.In addition, the detection of abnormal behaviour mode is to carry out according to the number of times that exists that has number of times and the place beyond these layers in first and second layers, and it is irrelevant with the mode that is close with the abnormal behaviour mode, thereby can avoid wrong detection, and can realize monitoring accurately operation.Further, can detect first to fourth abnormal behaviour mode by first to fourth monitoring operation, and can give the alarm in response to any one detection in these abnormal behaviour modes, thereby it is unusual to detect water quality according to the multiple abnormal behaviour mode of aquatic organism, and this can realize more safe water quality monitoring operation.In addition, because the fish of being observed is monitored in a plurality of monitoring parts, and alarm is just sent in response to the detection of the abnormal behaviour mode in all monitoring parts, even for example having only, a fish presents the abnormal behaviour mode, behavior other fishes is under the situation of normal condition, can make the just problematic judgement of this fish, thus can realize not being subjected to the fish observed health status etc. influence, water quality monitoring more accurately operates.

It should be understood that aforesaid description has only related to most preferred embodiment of the present invention, and present invention includes all changes and the correction of its embodiment that is used for illustration purpose, and these variations and correction do not break away from the spirit and scope of the present invention.
