Below, more detailed structure and the processing of detection information processing mechanism 104 are described.Fig. 3 is the block diagram of the structure of expression detection information processing mechanism 104.Fig. 4 A, Fig. 4 B are for the chart of explanation by storing mechanism 143 canned datas of detection information processing mechanism 104.Fig. 4 A represents each the judgement project of information and relation of result.Fig. 4 B represents that the alarm of setting corresponding to fingerling produces the example of condition data.
Detection information processing mechanism 104 comprises to be judged with information testing agency 141, alarm control mechanism 142, storing mechanism 143, demonstration data generation mechanism 144.
Generate mechanism 144 outputs to judging with information testing agency 141 with showing data from the detection data that receives signal processing mechanism 103 outputs.Show that data generate mechanism 144 and generate the display image data that brightness is carried out gray processing based on detection data, and to indication mechanism 105 outputs.
Judge the judgement information that detects multiple types with information testing agency 141 based on detection data.Particularly, for example, judge the in advance storage thing mark detection threshold value with information testing agency 141, use threshold value if the data level (being equivalent to reflection strength) of each distance (degree of depth) position of detection data is higher than the detection of thing mark, then judge in this position existence mark (shoal of fish or monomer fish, seabed).At this moment, for example, judge with information testing agency 141 and judge the seabed based on the continuous data level of repeatedly giving birth to pulse or in the data level that distance (degree of depth) direction is arranged.And, if judging to detect comparing with the position that is judged to be the seabed to exist by the sea side with information testing agency 141 is higher than the data level that the thing mark detects the usefulness threshold value, then is judged as and has the shoal of fish or monomer fish in this position.Accordingly, judgement obtains the judgement information relevant with having or not the shoal of fish or monomer fish with information testing agency 141.Should judgement relevant with having or not the shoal of fish or monomer fish can select a kind of in two kinds of " having ", " nothing " with information.
If judge that detecting the shoal of fish or monomer fish with information testing agency 141 is the judgement information of " having ", then calculate the degree of depth of this shoal of fish or monomer fish, obtain the judgement information of the degree of depth.The judgement of the degree of depth is set according to numerical value (for example, " m ") with information.
Judge with information testing agency 141 by judging substrate with detected sub sea location as the level of the detection data of distance (degree of depth) the direction arrangement of benchmark.It has utilized according to the electrical level transfer different characteristic of substrate at the detection data of the distance take sub sea location as benchmark (degree of depth) direction arrangement.Judge any conduct judgement information relevant with substrate that detects in " rock ", " stone ", " sand ", " mud " with information testing agency 141.
In addition, judge to be not limited to these three kinds with information, so long as the electrical level transfer of detection data corresponding to fingerling and different information, just can be contained in the test item of judgement usefulness information testing agency 141.
Satisfy these condition with each judgement that information testing agency 141 obtains with information if alarm control mechanism 142 is judged from judgement, then sound generating mechanism 106 is carried out sounding control, in order to give the alarm.For example, shown in Fig. 4 B, the alarm that alarm control mechanism 142 makes expression and alarm produce the detection of the related fingerling FishA of condition data DA1 foundation is sent by sound generating mechanism 106.At this moment, alarm control mechanism 142 can be to showing that data generate the notice image that mechanism's 144 output expressions detect fingerling FishA.
On the other hand, alarm control mechanism 142 is not as long as not satisfying alarm generation condition data DA1 from judging that each that obtain with information testing agency 141 judged with the information any one, just carry out from the control of sound generating mechanism 106 sounding.
Accordingly, even for the required judgement information of the fingerling that detects appointment is a plurality of, judge at each not give the alarm when satisfying other condition with information, only when satisfying for the required full terms of the fingerling that detects appointment, give the alarm.For example, when the fingerling FishA of appointment is set as medium-sized porgy, having the degree of depth that has monomer fish echo, this echo is 50m～150m(winter) and the substrate in seabed in life marine site be this feature of rock, therefore only when satisfying all these conditions, send the alarm that expression detects the fingerling FishA of appointment.On the other hand, in fish detector in the past, give the alarm when having echo, when the degree of depth is consistent, again give the alarm, when judging substrate as rock, give the alarm again., it is multiple to exist the fish of echo to have, and the fish that the degree of depth is suitable also has multiple, and the fish that lives in substrate and be the marine site of rock also has multiple, therefore in method in the past, and can not be fully and notice detects appointment necessarily fingerling FishA.
So, as long as utilize structure and the processing of present embodiment, can be more accurately and suitably notify the detection of the fingerling of the required appointment of user.
When being carried out the alarm generation processing that realizes by a series of structure described above by computing machine, can carry out sequencing and storage to treatment scheme shown in Figure 5, and carry out by computing machine.Fig. 5 is the process flow diagram that the expression alarm produces treatment scheme.
At first, according to the echo signal form detection data (S101) of ultrasonic pulse signal.Then, based on detection data, as mentioned above, detect various judgements information (S102).
Then, for according to fingerling and in a plurality of alarm generation conditions of setting in advance each, checking is judged with information (S103).And, only have and judge that satisfying all alarms with information produces condition (S104: be), just produces alarm and sends (S105).If judge with information and do not satisfy in a plurality of alarm generation conditions one, then do not produce alarm (S104: no).
In addition, in the above description, the frequency that shows ultrasonic pulse signal is the situation of single-frequency, but in the situation of utilizing the ultrasonic pulse signal that is made of two kinds of different frequencies, can have or not for each frequency detecting the echo of the shoal of fish or monomer fish.Accordingly, can further obtain the judgement information relevant with the shoal of fish that has or not the feature that meets fingerling or monomer fish.
In addition, in the situation of utilizing the ultrasonic pulse signal that is consisted of by two kinds of different frequencies, can carry out more accurately substrate and judge.This is difference owing to the substrate kind of the electrical level transfer reason " rock " of the echoed signal (detection data) of double frequency, " stone ", " sand ", " mud " formation.Accordingly, also can judge more accurately substrate.
Therefore, as long as utilize the ultrasonic pulse signal that is consisted of by two kinds of different frequencies, and produce condition for each frequency setting alarm, just can detect more accurately the fingerling of appointment and suitably notify to the user.
In addition, in the above description, only take the echo that has or not the shoal of fish and monomer fish as condition, but also echo strength can be divided into interimly " height ", " in ", " low ", " nothing " etc., be used for alarm and produce condition.In addition, not only the degree of depth of the echo of the shoal of fish and monomer fish also can be used for alarm with seabed depth and produce condition.So, by the condition of judging usefulness is carried out sectionalization, multiple types, the just more accurately detection of the fingerling of realize target.
Then, the related supersonic sounding device of contrast description of drawings the second embodiment.Fig. 6 is the block diagram of the structure of the related supersonic sounding device 10A of expression the second embodiment of the present utility model.Fig. 7 is the block diagram of the structure of expression detection information processing mechanism 104A.
In the related supersonic sounding device 10 of the first above-mentioned embodiment, show the example of only using information according to the judgement from the detection of the backscatter signal in the water that is obtained by probe 101, but in the supersonic sounding device 10A of present embodiment, the measurement data that further also is used to autobiography sensor 108 detects judges the information of using.In addition, in the supersonic sounding device 10A of present embodiment, what show the storage multiple types produces condition group's situation for the alarm of fingerling.
Judge with the 141A of information testing agency obtain shown in the first embodiment the judgement relevant with having or not the shoal of fish or monomer fish with the judgement of information, the degree of depth with information, and the substrate judgement of being correlated with the judgement information of information and water temperature.The judgement of water temperature is set with numerical value (for example " °: degree centigrade ") with information.
In storing mechanism 143, the alarm that stores two kinds of setting for each fingerling produces condition data D
A2, D
B2Produce condition data D in alarm
A2, D
B2In, include as required the alarm relevant with water temperature and produce condition.
The alarm that alarm control mechanism 142 reads by storing mechanism 143 storages produces condition data DA2, D
B2 Alarm control mechanism 142 produces condition data D for alarm
A2, D
B2Each and each judge with information relatively.That is, alarm control mechanism 142 compares alarm generation condition data D
A2Each condition and each judge the information of use, and alarm generation condition data D relatively
B2Each condition and each judgement information.
As long as judge that satisfying alarm with information produces condition data D
A2All conditions, alarm control mechanism 142 just sends corresponding to producing condition data D with alarm
A2The alarm of the first related fingerling.On the other hand, as long as judge that not satisfying alarm with information produces condition data D
A2All conditions in one, alarm control mechanism 142 does not just send corresponding to producing condition data D with alarm
A2The alarm of the first related fingerling.
In addition, as long as judge that satisfying alarm with information produces condition data D
B2All conditions, alarm control mechanism 142 just sends corresponding to producing condition data D with alarm
B2The alarm of the second related fingerling.On the other hand, as long as judge that not satisfying alarm with information produces condition data D
B2All conditions in one, alarm control mechanism 142 does not just send corresponding to producing condition data D with alarm
B2The alarm of the second related fingerling.
At this moment, as long as alarm control mechanism 142 makes alarm song for the first fingerling from different for the alarm song of the second fingerling, the user just can judge detected fingerling by sound.This can realize by the following method, the method is, for example, and by produce the related information of setting up of condition and fingerling for the alarm by storing mechanism 143 storages, further set up in advance the information of storing sounding sound, alarm control mechanism 142 produces condition with alarm and together reads relatedly.
Accordingly, even set the detection alarm of a plurality of fingerlings, also can send exactly detection alarm for each fingerling.
In addition, so store when producing the condition group for the alarm of a plurality of fingerlings, also can select and utilize the alarm of each fingerling to produce the condition group.For example, when storing relatively alarm generation condition data with a plurality of fingerlings, can select the one or more Rule of judgment for alarm control in these.
Identical fingerling in addition, in above-mentioned processing, produces condition for each fingerling setting alarm, even but in the marine site of living not simultaneously, also can individually be set alarm generation condition and utilization.
So, produce condition as long as utilize the structure of present embodiment just can further increase alarm, therefore can further accurately and suitably notify the detection of the fingerling of the desirable appointment of user.
In addition, in the present embodiment, show in order to the example of cooling-water temperature sensor, but also utilizable energy is enough measured sensor because of the characteristic of different other of fingerling.
In addition, by the structure of each above-mentioned embodiment is appended, comprise the fish length measuring ability, also can further increase alarm and produce condition.Accordingly, can judge more accurately the detection of specifying fingerling.For example, when being above-mentioned porgy, fish length is 30cm～100cm, therefore can set so condition.
In addition, also can be according to the fish length changing warning.Only when detecting the fish of the fish length that surpasses regulation, just send the alarm of appointment, so can judge exactly the fish that detects more than the fish length that allows to fish for, be of value to the protection of aquatic resources.In addition, fish length is determined with effect to fingerling, so as long as only send the alarm of appointment when the monomer fish of the fish length scope that detects regulation, the user just can judge the fingerling that detects target more accurately.In addition, further, for each fingerling, there are feature in the life of fish, the fish layer that moves about, therefore as long as the fish length of rmc monomer fish and the degree of depth that detects this monomer fish are sent the control of the alarm of appointment, just can judge more accurately to detect the required fingerling of user.
In addition, also can with date information adding constantly to above-mentioned judgement with in the information, accordingly, in the situation of migratory fish etc., the life position is different because of season, the moment etc., but further considers season and the judgement that just can specify exactly the detection of fingerling constantly.
In addition, in the above description, the value that shows the degree of depth and water temperature is used for the example that alarm produces condition, but also variation or the temperature variation of the degree of depth can be used for alarm generation condition.
In addition, in the above description, show the example that pre-stored alarm produces condition, produce condition but the user also can produce the new alarm of conditioned disjunction registration based on the achievement changing warning of fishing.At this moment, the user sets change or sets the operational processes of registering by 192 pairs of operation input mechanisms 107 of operating operation button.Accordingly, 104 pairs of detection information processing mechanisms show that data generate mechanism 144 and show control so that on detection image 151 display setting with window 152.Accordingly, as shown in Figure 2, display setting window 152.
The user sees on the limit to set with window 152 limits and carries out change or the registration that each alarm produces conditioned disjunction fingerling name.At this moment, if carry out and will be shown in the lump the demonstration that the alarm of setting with window 152 produces the position etc. of condition with information by judging with information testing agency 141, the detected judgement of 141A, then the user can carry out simply alarm and produces the change of condition or new registration formalities.
