According to an embodiment of the present utility model, except comprising the first judging part in judging part, the second judging part and the 3rd judging part can also be comprised.Fig. 4 is the circuit structure diagram of an embodiment for the second judging part in the testing arrangement of sit-ups of the present utility model; Fig. 5 is the circuit structure diagram of an embodiment for the 3rd judging part in the testing arrangement of sit-ups of the present utility model.
As shown in Figure 4, whether the second judging part lies down for detecting people, its input is the signal of telecommunication (its value is V1 and V2) be directly proportional to L1 and L2, and whether the value V1+V2 being carried out the signal of telecommunication corresponding to the distance sum that two range finder modules detect by Circnit Layout is less than the comparison of predetermined value, when determining that V1 and V2 sum is less than predetermined value, export a low level, namely judge that experimenter lies down.
The circuit structure of the second judging part is not limited thereto, and can also be by Circnit Layout to carry out the comparison whether V1 and V2 be respectively less than predetermined value, and this predetermined value can be set to correspond to the voltage that actual detection distance exports for range finder module during 3cm.
As shown in Figure 5, the 3rd judging part is embodied as rest-set flip-flop Q3, and its input receives respectively from the output signal OUT-S of the first judging part and the output signal OUT-R from the second judging part, and then judged result OUT-STATE exports by rest-set flip-flop Q3.Rest-set flip-flop Q3 can guarantee after experimenter sits straight keep export high level, only have when determine experimenter for couch state time ability output low level, can stable output be ensured thus.
The circuit structure of the 3rd judging part is not limited thereto, and can also adopt the digital circuit of other structures to realize, as long as can realize carrying out comprehensive descision and the circuit of output result signal all can adopt to sit up status signal and the status signal that couches.
According to an embodiment of the present utility model, in testing arrangement of the present utility model, can also filter circuit be comprised, carry out filtering process for the signal of telecommunication exported range finder module.Fig. 6 A and Fig. 6 B is the circuit structure diagram of an embodiment for the filter circuit in the testing arrangement of sit-ups of the present utility model, as shown in the figure, filter circuit carries out filtering to the signal of telecommunication that range finder module exports, and and isolation processing is carried out to the signal of telecommunication, to increase the driving force of input signal.
Fig. 7 is the schematic block diagram of the first scheme of the testing arrangement for sit-ups of the present utility model, as shown in the figure, the signal of telecommunication S1 and S2 from the first and second range finder modules is input in the filter circuit as shown in Fig. 6 A, Fig. 6 B, input the first judging part and the second judging part after filtering afterwards respectively and carry out sit up detection and detections of lying down, each detection signal inputs the signal exporting the action that to sit up about the standard that whether completes after the 3rd judging part carries out comprehensive descision.
Referring to Fig. 8 A and Fig. 8 B, the principle of the alternative plan of the testing arrangement for sit-ups of the present utility model is described.As shown in the figure, in this scenario, the setting angle θ 2 of the second range finder module 10 is 90 °, and the setting angle θ 1 of the first range finder module 10 is less than θ 2.
As shown in Figure 8 A, experimenter is in the process of sitting up, and have a moment to be in as upper/lower positions: namely the experimenter crown is just directly over the second range finder module, subject's head H leaves the range finding direction of the second range finder module subsequently.Before and after this moment, the distance L2 that second range finder module detects can produce a sudden change, become very large value from a less value, this is because the range finding direction of the second range finder module loses shutter body, thus its find range from the range maximum for this test module.
The distance L1 that when being in directly over the second range finder module A point place by the measurement experimenter crown in this programme, the first range finder module and the second range finder module record and L2, analyze experimenter and complete distance that when sitting up action, (attitude in Fig. 8 B) first range finder module should measure A point as shown in the figure and D point (D point not necessarily head, but also may be certain position of back S, there is not such must being related to of BE=BD) between distance, when the L1 that the first range finder module records is greater than the AD in Fig. 8 B judge experimenter complete the action that sits up.
As shown in Figure 8 B, be CF ⊥ AE and meet at F point, thus have following relational expression:
AF＝L1*sin(θ1) (9)
EF/AF＝EC/CB＝CA/CD (10)
EF＝AE-AF＝L2-L1*sin(θ1) (11)
Can obtain according to formula (9), (10) and (11):
AD＝L1*L2/(L2-L1*sin(θ1)) (12)
That is, the distance L1 measured when the first range finder module is more than or equal to the AD value in formula (12), then judge that experimenter completes rising of a standard and sits action.
Fig. 9 to Figure 13 is the circuit structure diagram of an embodiment of the first judging part in the alternative plan of the testing arrangement for sit-ups of the present utility model.
The signal of telecommunication (being labeled as IN_A_L1 and IN_A_L2 in figure) that it is V1 and V2 that circuit part is as figure 9 used for according to its value corresponding to L1 and L2 of input exports the signal of telecommunication (being labeled as V-DETV2-V1k in figure) corresponding to (L2-L1*sin (θ 1)), and its value is (V2-V1*sin (θ 1)).
Different values can be got for different angles θ 1, R13.As θ 1=45 °, sin (θ 1)=0.707, then need (R14+R15)/(R13+R14+R15)=0.707.If R14+R15=20K, then R13=(20/0.707-20) K=8.28K, therefore for θ 1=45 °, R13=8.28K.For the θ 1 of 30 °, in like manner R13=20K can be calculated.Other values of θ 1 in like manner can calculate the resistance required for each resistance.
Circuit part shown in Figure 10 comprises multiplier and amplifier, Circnit Layout is the signal of telecommunication (being labeled as V-DETV2-V1k in figure) corresponding to (L2-L1*sin (θ 1)) exported according to the circuit corresponding to the signal of telecommunication (being labeled as IN_A_L1 and IN_A_L2 in figure) that its value of L1 and L2 is V1 and V2 and Fig. 9 of input, export the signal of telecommunication V-UP corresponding to L1*L2/ (L2-L1*sin (θ 1)), its value is V1*V2/ (V2-V1*sin (θ 1)).
Circuit part shown in Figure 11 is switch holding circuit.In this partial circuit, the output being labeled as the amplifier of U3A for gauge tap device Q2 conducting whether.When the value V2 corresponding to the signal of telecommunication of L2 inputting amplifier U3A is less than L2-NMAX, Q2 conducting, signal of telecommunication V-UP is input in amplifier U3C, now the output V-UP00=V-UP-1=V-UP=L1*L2/ (L2-L1*sin (θ 1)) of this switch holding circuit.
Wherein L2-NMAX is that a ratio corresponds to the signal of telecommunication of maximum range of the second range finder module signal of telecommunication little a little.When V2 is less than this predetermined value L2-NMAX, then think that experimenter is also blocked directly over the second range finder module, at this moment V-UP00=V-UP.When V2 is greater than this predetermined value L2-NMAX, then represent that subject's head has left the range finding direction of the second range finder module, at this moment Q2 grid voltage KEY-KEEP is low, Q2 disconnects, V-UP00 remain experimenter leave the range finding direction of the second range finder module before the V1*V2/ (V2-V1*sin (θ 1)) that calculates of the circuit of Fig. 9-10.
Circuit part shown in Figure 12 is used for comparing the value of V1 and V-UP00 in real time and exporting comparative result OUT-S-1.The amplifier U3B output low level as V1 > V-UP00, otherwise all export high level.
The compare result signal OUT-S-1 that circuit part shown in Figure 13 exports for the circuit guaranteed only when the range finding direction of the second range finder module is left on the crown of experimenter shown in Figure 12 is just effective, that is, only when KEY-KEEP is low and OUT-S-1 is low, OUT-S is just low (for rest-set flip-flop, low level is significant level).
Also can comprise in above-mentioned alternative plan of the present utility model as shown in Figure 4 for judging the second judging part that whether experimenter lie down, the 3rd judging part for exporting final pose discrimination signal as shown in Figure 5, and as shown in Fig. 6 A, Fig. 6 B for carrying out filtering to the range finding signal of telecommunication and strengthening the filter circuit of signal driving force, omit it at this and illustrate.
Figure 14 is the schematic block diagram of the alternative plan of the testing arrangement for sit-ups of the present utility model.As shown in the figure, in alternative plan of the present utility model, after two find range signal of telecommunication S1 and S2 input filter circuits, the signal of telecommunication corresponding to L1*L2/ (L2-L1*sin (θ 1)) is produced by computing circuit, and keep the second range finder module from there being the signal of telecommunication corresponding to L1*L2/ (L2-L1*sin (θ 1)) blocking and do not block the moment when the second range finder module being lost and blocked by switch holding circuit, then compare by this signal of telecommunication with corresponding to the signal of telecommunication of the current output of the first range finder module, add the presence or absence shadowing of the second range finder module, constitute the first judging part circuit, combine the second decision circuitry of detecting for lying down and the 3rd decision circuitry for the such as rest-set flip-flop that exports final carriage signal simultaneously, constitute the framework of the alternative plan of testing arrangement of the present utility model.
