Control unit 410 is determined repetition period Tf in the following manner according to the represented focal length F of above-mentioned focus information that obtains.That is, control unit 410 is at first calculated from ultrasonic detector 200 by Ta=2F/C and sends ultrasonic signal receives the test object generation to ultrasonic detector 200 the needed time T a of reflection ultrasonic signal.Here " C " is hyperacoustic spread speed of ultrasonic detector 200 in the container.Control unit 410 is obtained repetition period Tf by Tf=ts+Ta+td then.Here " ts " is the hyperacoustic time span of transmission, and " td " is that reflection ultrasonic signal is from arriving ultrasonic detector 200 to disappearing the needed time.
Control unit 410 is by transmitting element 404 excitation ultrasonic oscillator 202a, so that send ultrasonic signal with the repetition period Tf that determines.The length of the transmitting time of 1 ultrasonic signal is above-mentioned ts.Ultrasonic oscillator 202a and the holding wire 23a of ultrasonic signal by encouraging by the test object reflection received by receiving element 405.Receiving element 405 keeps received signal one by one by the cycle.Receiving element 405 is after the finishing receiving of n cycle (n is an arbitrary integer) then, and sending the time started with the ultrasonic signal in each cycle is benchmark, with the received signal addition in n cycle keeping.Receiving element 405 sends to instrumentation unit 406 with the composite signal after the addition.Instrumentation unit 406 measures the eigenvalue of above-mentioned composite signal then, generates the instrumentation information of this eigenvalue of expression.
Control unit 410 is according to above-mentioned instrumentation information diagnosis ultrasonic detector 200.The diagnosis that control unit 410 carries out is that for example whether diagnostic ultrasound wave detector 200 is normal, also can be the diagnosis that any item relevant with ultrasonic detector 200 carried out.
Repetition period Tf determines behind the focal length of having considered ultrasonic detector 200.Therefore, when 2F/C is that the ultrasonic detector 200 of Ta1 is when being connected with adapter 401, with be that Ta2 (when the ultrasonic detector 200 of Ta2＜Ta1) is connected with adapter 401, changes and sets, make separately repetition period Tf1, Tf2 shown in Figure 16 A, 16B as 2F/C.Here owing to Ta2＜Ta1, so Tf1＜Tf2.Because repetition period Tf1, Tf2 are that time T s and time T d add that time T a1 or time T a2 determine, so shown in Figure 16 A, 16B, all be the transmission of carrying out ultrasonic signal after reflection ultrasonic signal disappears immediately under any situation.
Therefore,, can eliminate, the time in n cycle can be controlled to Min. from receiving reflection supersonic wave to the ineffective time the transmission of reflection ultrasonic signal next time according to the 2nd embodiment.Therefore, can carry out the diagnosis of ultrasonic detector 200 at short notice effectively.
[the 3rd embodiment]
The following describes the action of the diagnostic ultrasound equipment that relates to the 3rd embodiment.
Condition during diagnostic ultrasound wave detector 200 is the same with the 2nd embodiment.In addition, control unit 410 is to carry out of obtaining till the focus information the same with the 2nd embodiment of action.
Control unit 410 is determined repetition period Tf1, Tf2, Tf3......Tfn according to the focal length F shown in the focus information of obtaining by following mode.That is, control unit 410 is at first calculated from ultrasonic detector 200 by Ta=2F/C and is sent ultrasonic signal receives the test object generation to ultrasonic detector 200 the needed time T a of reflection ultrasonic signal.Control unit 410 is obtained the reference value Tf of repetition period by Tf=ts+Ta+td then.Then control unit 410 is obtained repetition period Tfi (i=1,2,3......n) by Tfi=Tf+j * (i-1).Here, j is a constant.That is, be reference value Tf with repetition period Tf1, Tf2, Tf3......Tfn increase constant j successively.
Control unit 410 repeats to send ultrasonic signal by transmitting element 404 excitation ultrasonic oscillator 202a.Each repetition period that this ultrasound wave sends is used above-mentioned definite Tf1, Tf2, Tf3......Tfn successively.Promptly as shown in figure 17, the repetition period in the 1st cycle is Tf1, and the repetition period in the 2nd cycle is Tf2.The transmitting time length ts of 1 ultrasonic signal is fixed.Therefore length T r1, Tr2, the Tr3......Trn of time of reception increase successively.
Receiving element 405 receives reflection ultrasonic signal at reception period.The same with the 1st embodiment then, receiving element 405 obtains composite signal with the received signal addition in n cycle.
Because ultrasonic detector 200 is maintained above-mentioned state with test object, therefore as shown in figure 17, all roughly the moment of elapsed time Ta arrives ultrasonic detector 200 to original reflection ultrasonic signal after sending ultrasonic signal in each cycle.In addition, when producing the multipath reflection signal, this multipath reflection signal began to roughly the moment of elapsed time (N) Ta arrives ultrasonic detector 200 from sending ultrasonic signal in each cycle.When the time, (N) Ta was greater than Tfi, the multipath reflection signal after cycle arrive ultrasonic detector 200.At this moment, obtain by (N) Ta-Tri to the time T bi that receives the multipath reflection signal from the initial time in cycle of receiving the multipath reflection signal.That is, as shown in figure 17, the time T b1 relevant with the multipath reflection signal MF1 of the ultrasonic signal that sends in initial cycle is (N) Ta-Tr1.The time T b2 relevant with the multipath reflection signal MF2 of the ultrasonic signal that sends in the 2nd cycle is (N) Ta-Tr2.Because time T r1, Tr2, Tr3......Trn gradually change, time T b1, Tb2, Tb3......Tbn also change successively.Therefore, the timing of reception multipath reflection signal also changes with each cycle in one-period.
Like this, when send with the ultrasonic signal in each cycle the time started be benchmark with the received signal addition separately of n cycle after the time because original reflected signal occurs at one time, so its level approximately becomes n times during addition.But, because the appearance of multipath reflection signal discrete ground, so addition hardly.Therefore, as shown in figure 18, the composition of original reflection ultrasonic signal is much larger than the composition of multipath reflection signal in the composite signal.
Like this, according to the 3rd embodiment, can easily distinguish reflection ultrasonic signal composition and multipath reflection signal component in the composite signal.Therefore, ultrasonic detector 200 is diagnosed, can have been reduced the suitable diagnosis of the influence of multipath reflection signal by the characteristic quantity that only is conceived to the composite signal relevant with the reflection ultrasonic signal composition.
In addition, according to the 3rd embodiment, determining of the minima of repetition period is the same with the 2nd embodiment.Therefore, each repetition period Tf1, Tf2, Tf3......Tfn can be suppressed can diagnose effectively at short notice for necessary Min..
The the 2nd or the 3rd above embodiment can have following various distortion.
When determining repetition period Tf in the 2nd embodiment and the reference value Tf in the 3rd embodiment, can add some surpluses.
In the 2nd or the 3rd embodiment, the value that maintainer can be imported is as focal length.
In the 2nd or the 3rd embodiment, the ultrasonic detector 200 and the spacing distance of test object are adjusted into the focal length of ultrasonic detector 200 consistent,, focal length are determined the repetition period as spacing distance as prerequisite.But above-mentioned spacing distance is not necessarily leaveed no choice but consistent with focal length.If spacing distance and focal length are inconsistent, should judge spacing distance, determine the repetition period according to this layout distance.For example, when determining spacing distance, can from the data base, obtain according to each ultrasonic detector 200 or each kind.Perhaps can obtain by the spacing distance of maintainer input.
In the 2nd or the 3rd embodiment, also can not synthesize the signal in a plurality of cycles, for example respectively with reference to the diagnosis of the characteristic quantity of each signal institute instrumentation being carried out ultrasonic detector 200 etc.
In the 3rd embodiment, the setting of the minima of repetition period also can be irrelevant with focal length.
In the 3rd embodiment, the changing method of repetition period also can be arbitrarily.For example, can change the recruitment of repetition period.In addition, can also reduce the repetition period successively.Also the repetition period can be increased and decreased repeatedly.
In the 2nd or the 3rd embodiment, by having the matrix switch of multiplexer structure, can be with transmitting element 404 and receiving element 405 as 1 channel design.Thus, can reduce the circuit scale of transmitting element 404 and receiving element 405.
Also can carry out the demonstration of the signal that generates based on display processing unit 409 by display unit 411d.For example, display processing unit 409 is connected with image generation unit 411b.Then, image generation unit 411b generates the corresponding video data of signal that generates with display processing unit 409, and is written to memory element 411c, and is shown by display unit 411d.

When being necessary the signal line states of ultrasonic detector 600-1 or detector 600-2 diagnosed, control unit 514 carries out processing shown in Figure 22.
Among the step Sc1, control unit 514 reads in the identifying information of identifying information output unit 604 or 615 outputs of identifying information output unit.In step Sc2, control unit 514 is judged the type photodetector of ultrasonic detector 600-1 or 600-2 according to above-mentioned identifying information.Identifying information does not comprise the information of representing type photodetector for the information of each ultrasonic detector of difference.Control unit 514 is judged type photodetector by with reference to the data base who records the type photodetector corresponding with various identifying informations.The data base can obtain from the ancillary equipment that is connected with adapter 502, also can be stored in the storage medium 507.In addition, also can comprise the information of representing type photodetector in the identifying information, directly judge type photodetector according to this information.
Type photodetector is the 1st time-like, and control unit 514 advances to step step Sc3 by step Sc2.Among the step Sc3, control unit 514 is selected the B terminal of the 1st switch 512-1～512-n as shown in figure 20.Common the 1st switch 512-1～512-n selects the A terminal.Begin then to apply voltage Vsup1 respectively to each holding wire 603a.
The voltage of holding wire 603a is not to reach voltage Vsup1 immediately, but rises gradually.This is because there is the capacity load composition when adapter 601 is seen contact unit 602.When the moment that holding wire 603a applies voltage was benchmark, the voltage of the holding wire 603a of t was corresponding with the state of holding wire 603a constantly, changes as shown in figure 23 with beginning.Promptly, if holding wire 603a is under normal situation, the voltage of holding wire 603a is represented with V during t constantly, then under the situation of holding wire 603a short circuit, the voltage of holding wire 603a be the V1 littler than V during t constantly, under the situation that holding wire 603a disconnects, the voltage of holding wire 603a is the V2 bigger than V during moment t.
Then, in step Sc4, control unit 514 begins to wait for elapsed time t from switch the 1st switch 512-1～512-n among step Sc3, then at step Sc5, the voltage of each holding wire 603a, i.e. the voltage V (CH) of each passage when from receiving element 505, obtaining moment t.At step Sc6, control unit 514 judges that voltage V (CH) surpasses above-mentioned voltage V and adds that the passage of the value of allowable error ε is an off-state.Among the step Sc7, control unit 514 judges that it is short-circuit condition that voltage V (CH) are lower than the passage that above-mentioned voltage V deducts the value of allowable error ε.Then at step Sc8, control unit 514 is judged other passages, i.e. the passage of V (CH) in V ± ε scope is for normally.
And the value of suitable moment t, voltage V, allowable error ε that is used for above-mentioned judgement is difference with the difference of the kind of ultrasonic detector.Therefore, by which kind of value t, voltage V, allowable error ε adopt be documented among the above-mentioned data base constantly, the identifying information of in step Sc1, obtaining according to control unit 514, from above-mentioned data base, obtain the mode that the value of t, voltage V, allowable error ε is constantly used, can improve accuracy of detection.At this moment, voltage generating unit 510 changes the voltage Vsup1 that produces under the control of control unit 514.Equally, also can its resistance value be changed with resistor 511-1～511-n as rheostat.
Type photodetector is the 2nd time-like, and control unit 514 advances to step Sc9 by step Sc2.Among the step Sc9, control unit 514 is selected the A terminal of the 1st switch 512-1～512-n, shown in solid line among Figure 21, selects the C terminal of the 2nd switch 513-1,513-2 simultaneously.Control unit 514 advances to step Sc11 then.
On the other hand, type photodetector is the 3rd time-like, and control unit 514 advances to step Sc10 by step Sc2.Among the step Sc10, control unit 514 is selected the A terminal of the 1st switch 512-1～512-n, simultaneously as shown in phantom in Figure 21, selects the D terminal of the 2nd switch 513-1,513-2.Control unit 514 advances to step Sc11 then.
Promptly, among the ultrasonic detector 600-2 of the 3rd class, if electronic circuit 613 is not supplied with the voltage ± Vsup3 different with voltage ± Vsup2, just can't apply the enough bias voltages that are used to detect, so voltage ± Vsup3 supplies to electronic circuit 613 by the 2nd switch 513-1,513-2 to holding wire 614a.Relative with it, among the ultrasonic detector 600-2 of the 2nd class, because electronic circuit 613 service voltages ± can apply the bias voltage that is used to detect to holding wire 614a during Vsup2, so voltage ± Vsup2 supplies to electronic circuit 613 by the 2nd switch 513-1,513-2.
Among the step Sc11, control unit 514 is obtained the voltage of each holding wire 24a, i.e. the voltage V (CH) of each passage from receiving element 505.Among the step Sc12, control unit 514 judges that voltage V (CH) is normal more than or equal to the passage of threshold value Vth, and the passage of judging other is for opening circuit.
And the value that is used for suitable voltage ± Vsup2, the voltage ± Vsup3 of above-mentioned judgement and threshold value Vth with the difference of the kind of ultrasonic detector difference.Therefore, by adopting which kind of value to be documented among the above-mentioned data base voltage ± Vsup2, voltage ± Vsup3 and threshold value Vth, the identifying information of in step Sc1, obtaining according to control unit 514, from above-mentioned data base, obtain the mode that the value of voltage ± Vsup2, voltage ± Vsup3 and threshold value Vth is used, can improve accuracy of detection.
According to the 4th above embodiment, take place to judge that this is unusual when unusual at holding wire 603a, the 614a of ultrasonic detector 200,300 and adapter 601,611.Therefore, the reason that can judge ultrasonic detector 600-1,600-2 easily and do not have operate as normal is that fault by ultrasonic oscillator causes or is caused by the fault of cable distribution or adapter.
In other the 4th embodiment, have the device of the judgement signal line states that is conceived to line voltage signal indicial response characteristic and be conceived to be applied to the device of the judgement signal line states of the bias voltage on the holding wire, for ultrasonic detector 600-1 still is the ultrasonic detector 600-2 of the 2nd or the 3rd class, use above-mentioned 2 devices according to the diagnosis object that is connected with adapter 501 respectively.And the 4th in the embodiment, can be the 2nd or the 3rd class according to the ultrasonic detector 600-2 that is connected with adapter 501 selectively to electronic circuit 613 service voltages ± Vsup2 and voltage ± Vsup3, switches the voltage that offers electronic circuit 613.Thus, can diagnose the ultrasonic detector of the 1st to the 3rd class, can carry out the diagnosis of the ultrasonic detector of multimachine kind by enough 1 master units 500.
In other the 4th embodiment, judge the type photodetector of the ultrasonic detector 600 that is connected with adapter 501 according to the identifying information of ultrasonic detector, and can be according to the judged result diagnostic action that automaticallyes switch, so the operator there is no need to note the type photodetector as the ultrasonic detector 600 of diagnosis object.Therefore can alleviate operator's burden.
The 4th embodiment can have following various variation.
Can diagnose 3 type photodetectors of the 1st to the 3rd respectively, also can be only a kind or 2 kinds of type photodetectors be diagnosed.
The time that also can reach voltage V to the diagnosis of ultrasonic detector 600-1 according to the voltage of holding wire 603a carries out.
Diagnosis to ultrasonic detector 600-1 also can only judge whether normally.
By having the matrix switch of multiplexer structure, can be with transmitting element 504 and receiving element 505 as 1 channel design.Thus, can reduce the circuit scale of transmitting element 504 and receiving element 505.In addition, the output of voltage Vsup1 that makes voltage generation unit 510 makes resistor 511 and the 1st switch 512 respectively as a system as 1 system simultaneously.
The method that changes the state that applies of voltage Vsup1 can be any.For example, can make voltage Vsup1 is negative voltage.The level of the voltage Vsup1 that applied can be raise or reduces.When changing the level of voltage Vsup1, polarity that both can fixed voltage Vsup1 also can be reversed it.
The demonstration of the signal that generates according to display processing unit 509 can be undertaken by display unit 515d.For example, display processing unit 509 is connected with image generation unit 515b.Image generation unit 515b generates the corresponding video data of signal that generates with display processing unit 509 then, and is written to memory element 515c, is shown by display unit 515d.
Also can realize the ultrasonic detector diagnostic equipment even omit medical diagnosis unit 515.
