(first embodiment)
With reference to Fig. 1, Fig. 2 first embodiment is described.Fig. 1 be with present embodiment related sandwich use in the detecting device be used for the skeleton diagram of two fans during double doors near detecting sensor 1, Fig. 2 is close the door the figure near the relation of the position between detecting sensor and the door-plate under state and the door opening state of expression.
As shown in Figure 1, sheet near detecting sensor 1, the face side relative that is installed in doorframe (perhaps door pillar) 2 with door-plate 3.Spread all over roughly installing endlong of doorframe 2 near detecting sensor 1.
Here, as sheet near detecting sensor, use for example a kind of like this sensor, it has the check-out console that comprises pair of electrodes, comes human body etc. approaching by the electrostatic capacitance change of check-out console.For example, preferred following near detecting sensor, wherein, make the inductance (L) that has based on coiled type partly, electric capacity (C) partial sum real component (R) and be scattered in the mother metal and constitute sensor element as the coiled type carbon fiber that the LCR resonance circuit plays a role, and have the pair of electrodes that is electrically connected with this sensor element, between two electrodes, be connected with high-frequency oscillating circuits and be connected with the detecting circuit that the signal that changes based on the LCR resonance circuit is detected.As an example, figure 3 illustrates the equivalent circuit of such sensor element.As shown in Figure 3, coiled type carbon fiber 12, based on its coil shape (spiral-shaped), as electromagnetic property, have respectively intrinsic inductance (L) partly, electric capacity (C) part and resistance (R) part.And, between a plurality of coiled type carbon fibers 12, connect via the electric capacity that forms based on mother metal 13 (C) part.Therefore, coiled type carbon fiber 12 forms the LCR resonance circuit based on the LCR part, and and comprise between the mother metal 13 of a plurality of coiled type carbon fibers 12 and form the composite resonant circuit.
Next, the circuit near detecting sensor 1 is described.As shown in Figure 4, testing circuit 16 has: the high-frequency oscillating circuits (alternating current circuit) 19 that sensor element 11 is applied high-frequency signal; The amplifying circuit 20 that output signal from sensor element 11 is amplified; Be transfused to from the signal of amplifying circuit 20 and from the detecting circuit 22 of high-frequency oscillating circuits 19 via the signal of phase adjusting circuit 21; And output circuit 23.In detecting circuit 22, according to from the signal of amplifying circuit 20 with relatively obtain output signal from the signal of high-frequency oscillating circuits 19.Sensor element 11 has intrinsic impedance, and detected object thing 24 also has intrinsic impedance.Apply the high-frequency signal of preset frequency from 19 pairs of sensor elements 11 of high-frequency oscillating circuits, so near sensor element 11, produced AC field.In addition, except electric capacity (C) part that sensor element 11 is had, between sensor element 11 and detected object thing 24, also there is electric capacity (C) part, so when detected object thing 24 proximity sensor element 11, the integral body of two electric capacity (C) part changes.Because such overall variation, cause from detected object thing 24 to sensor element the single-piece impedance variations till 11.In addition, under the situation that detected object thing 24 has contacted with sensor element 11, the integral body of the resistance of sensor element 11 and detected object thing 24 (R) part changes, and its variation causes from detected object thing 24 to sensor element the single-piece impedance variations till 11.And, the variable quantity of single-piece impedance makes the voltage and the phase change of the high-frequency signal that puts on sensor element 11, at amplifying circuit 20 its variable quantity is amplified, then with its input detecting circuit 22, be detected with the high-frequency signal of importing detecting circuits 22 through phase adjusting circuit 21 from high-frequency oscillating circuits 19, thereby detect because the continuous variation near the impedance that is caused of detected object thing 24.The detection signal of gained is transported to output circuit 23, is output as for example voltage from output circuit 23.
So long as such near detecting sensor, approaching for the detected object thing, the detection sensitivity height, and can detect with stable status, so preferred.
When between doorframe 2 and door-plate 3, sandwich foreign matter, foreign matter with respect near detecting sensor 1 near to or in contact with the time, detect near detecting sensor 1 and to sandwich, so that door-plate 3 oppositely directed modes are exported.Parallel near detecting sensor 1 with door-plate 3, even door-plate 3 opens and closes, also keep certain near the distance of detecting sensor 1 and door-plate 3.Therefore, the short of foreign matter that sandwiches does not just have contact or close object near detecting sensor 1, so can not react near detecting sensor 1.
In addition, as shown in Figure 2, even under the state of closing the door and door opening state as the movable boundary of door-plate 3, door-plate 3 can not break away from the detection range near detecting sensor 1 yet, be held at a certain distance in front, so can not react near detecting sensor 1 always.
According to the present invention, can with simple texture ratio in the past structure more accurate, promptly sandwich detection.In addition, by monitoring that waveform can detect breakage and/or fault, also can easily judge whether normal operation.
(variation)
Near detecting sensor 1, sandwich even without detecting, also export faint waveform according to door-plate 3 and/or environment on every side etc. always.So, by monitor waveform always, under the situation of not exporting faint waveform, can infer near the damaged of detecting sensor 1 or sandwich the fault of detecting device, also can easily judge whether normal operation.
