FIG. 1 shows a configuration diagram of a first embodiment of the present invention. The monitoring system 21 shown in FIG. 1 is roughly divided into a transmitter 22 as a transmitting unit, a receiver 23 as a receiving unit, a response signal output unit 24 as a detected unit, and an alarm monitoring panel 2.
5 and.

The transmitter 22 is installed as a monitoring place at an entrance / exit of an elderly person insurance facility, a welfare facility, an ordinary household, etc., or at an entrance / exit of a private room and a common section, a common section and a common section, etc. inside these rooms. In addition, a transmitter 31 that transmits a radio wave of a predetermined frequency and a light emitter 32 that emits light are provided in the field at the opening of the entrance.

Send more.

Next, FIG. 3 shows another block diagram of the response signal output means of FIG. FIG. 3A is an explanatory configuration diagram, FIG.
(B) is a concrete block diagram. Figure 3 (A), (B)
Is a case where identification of the person to be detected is necessary, and the response signal output means 24A shown in FIG. 3 (A) is provided after the response signal generation means 53 and before the transmission means is provided with an individual code. The means 55 is provided. Note that the other structure is similar to that of FIG.

When the response signal from the response signal generating means 53 is input, the individual code assigning means 55 assigns an individual code for identifying the subject to the response signal and outputs it to the transmitting means 54. . Then, the transmitting means 54 transmits the response signal to which the individual code is added to the field.

Further, in FIG. 3B, the individual code assigning means 55 is provided after the oscillation circuit 64 which is the response signal generating means 53 and before the antenna 62 which is the transmitting means.
The modulation circuit 65 is a ROM (Re which stores the individual code of the detected person in advance).
Ad Only Memory) 66. In addition,
Antennas 61 and 62, detection circuit 63, and oscillation circuit 64
Is the same as that of FIG.

A response signal of a predetermined frequency (for example, a multiplied frequency of the received frequency) from the oscillation circuit 64 is a modulation circuit 6
5, the data is modulated based on the individual code of the person to be detected, which is stored in the ROM 66 in advance, and is output. Also,
The output signal from the modulation circuit 65, that is, the response signal to which the individual code is added, is transmitted from the antenna 62.

Then, such a response signal output means 2
4, 24A are formed in a tag type, a button type, or a capsule type, for example, and are carried by a person to be detected. Subsequently, FIG. 4 shows an explanatory view of carrying the response signal output signal of FIG.
In FIG. 4, the detected person 71 whose entrance and exit are monitored at the entrance / exit where the transmitter 22 and the receiver 23 are installed has the above-mentioned waist 71 of the clothes 72 (whether upper or lower) worn. The response signal output means 24 or 24A is attached by sewing. In addition, as shown by the broken line, the lower garment 72a
It may be attached to the skirt or footwear 73 by sewing or the like.

By attaching the response signal output means 24 or 24A to the waist of the garment 72, the skirt of the lower garment 72a, and the footwear 73 in this manner, the subject 71 is not affected by individual differences such as extension. In addition, it is possible to reliably detect the entrance and exit. Therefore, the operation of the monitoring system 21 will be described assuming that the response signal output means 24A is used. First, the transmitter 22 and the receiver 23 are installed so as to face each other across the opening of the entrance for monitoring. Further, the response signal output means 24A is, for example, a tag type, and is attached to the waist or the like of all clothes 72 owned by the detected person 71. The response signal output means 24A uses the frequency of the radio wave transmitted by the transmitter 22 as a resonance frequency, and transmits a response signal to which a different personal code corresponding to each of the detected persons 71 is added. Then, the transmitter unit 31 transmits a radio wave having a constant frequency to the field.

The radio wave transmitted to the field is first received by the receiving section 41 of the receiver 23, and the received signal from the receiving section 41 is input to the judging section 43. Further, the light from the light emitter 32 provided in the transmitter 21 is received by the light receiver 42, and the light reception signal from the light receiver 42 is also input to the determination unit 43.

Normally, the response signal output means 24A is placed in the electric field.
When there is no object, that is, when the detected person 71 is not present at the entrance / exit, the reception means 51 of the response signal output means 24A does not receive the radio wave from the transmitter 22, and therefore the frequency detection means 52 transmits from the transmitter 22. Since the frequency of the transmitted radio wave is not detected, the detection signal is not output from the frequency detection means 52, and the response signal is not output from the response signal output means 24A.

Therefore, since the received signal from the receiving section 41 of the receiver 23 is transmitted from the transmitter 22 and no response signal is input, the judging section 43 judges that the detected person 71 does not exist at the entrance / exit. Judgment is made and the alarm output command signal is not output. Next, in the electric field, the response signal output means 24A
Is present, that is, when the detected person 71 is present at the entrance / exit, the reception means 51 of the response signal output means 24A attached to the clothes 72 of the detected person 71 receives and receives the radio wave transmitted from the transmitter 22. Output a signal. This received signal is input to the frequency detection means 52, and it is determined whether or not the radio wave has the same frequency as the frequency of the radio wave transmitted from the transmitter 22 by resonating, and when the frequencies match (resonate). The detection signal is output.

When the detection signal is input to the response signal generating means 53, it outputs a response signal which is a multiplied frequency of the received frequency. This response signal is input to the individual code assigning means 55 to which the individual code is assigned, and the transmitting means 54 transmits the signal as a radio wave. In the receiver 23, when the response signal to which the individual code is added is input to the reception unit 41, the response signal and the individual code are output to the determination unit 43 as a reception signal, and the determination unit 43 stores the reference signal stored in advance. And the received signal are compared, and when they match, it is determined that the detected person 71 is present at the entrance. Further, when the reception signal is input to the determination unit 43, after confirming that the light from the light emitter 32 is blocked by the person to be detected 71 and the light is not detected by the light receiver 42, the alarm output command is issued. The individual code is output together with the signal.

When the alarm output command signal is input to the alarm output section 44, the alarm monitoring panel 24 of the monitoring center (monitoring room)
Based on the signal from the receiver 23 of which entrance or exit, who is at the entrance or the like based on the individual code, the alarm monitoring board 24 displays. In this case, an external speaker, a lamp, or the like may be activated to notify a monitor person (for example, a caregiver of the detected person 71) of the comings and goings of the detected person 71.

When the identification of the person to be detected is not necessary, the response signal output means 24 shown in FIGS. 2A and 2B is used. In this case, since the receiver 23 does not receive the individual code, the determination unit 43 outputs only the alarm output command signal. Therefore, the monitoring center (monitoring room) cannot identify the person to be detected.

If light is detected by the photodetector 42, the radio wave having the same frequency as the response signal is caused by a cause other than the response signal generating means 24 and the alarm output command signal is not output. In this way, the response signal generating means 24, 24
By attaching A to the clothes 72 or footwear 73 worn by the detected person 71, the detected person 71 carries the response signal generating means 24, 24A only by wearing his own clothes 72 or wearing the footwear 73. It becomes a state. Therefore, the person to be detected 71 can surely carry it without forgetting to carry it, and it is possible to more accurately detect the entering and leaving of the person to be detected 71.

The response signal generating means 24, 24A are
Since it is miniaturized by making it a tag type etc., it does not interfere with daily life. Further, the wearing position of the response signal generating means 24, 24A is set to be the waist of the clothes 72 of the person to be detected 71, the skirt of the lower garment 72a, or the footwear 73, which does not fluctuate depending on the individual, so that accurate entry / exit detection can be performed. it can.

Further, by adding an individual code corresponding to each of the detected persons 71 to the response signal transmitted from the response signal generating means 24A, it is possible to determine who is at the entrance from the individual code. It can be confirmed at the monitoring center. Next, FIG. 5 shows a block diagram of a second embodiment of the present invention. The monitoring system 21 shown in FIG. 5 has a transmitter / receiver 81 installed at the entrance / exit of a monitoring place, and is a combination of the transmitter 22 and the receiver 23 of the first embodiment.

The transceiver 81 is roughly classified into a timing signal output section 82, a transmission / reception section 83, a judgment section 84, and an alarm output section 8.
It is composed of 5. The determination unit 84 and the alarm output unit 85 are the same as those in the first embodiment, and the response signal output means 24 or 24A carried by the person to be detected 71 and the alarm monitoring panel 25 as the notification means are the same as in the first embodiment. Is.

The timing signal output unit 82 is the transmission / reception unit 8
A timing signal indicating the timing (for example, 0.1 sec cycle) at which the state 3 is switched to transmission or reception is output. The transmitting / receiving unit 83 transmits a radio wave having a predetermined frequency to the field (opening of the entrance / exit) based on the timing signal, and receives a radio wave from the field. Then, the control unit 86 receives the timing signal and receives the transmission / reception unit 83 and the determination unit 84.
And outputs an alarm output command signal to the alarm output unit 85.

In this embodiment, the light emitter 32 and the light receiver 42 as in the first embodiment are not installed. Therefore, the determination unit 84 determines the presence of the detected person 71 based on the received signal from the transmission / reception unit 83. The monitoring system 21 shown in FIG. 5 is set to transmit radio waves of a predetermined frequency to the field when the transceiver 83 is in the transmission mode. First, the timing signal output means 82 has a specific cycle (for example, 0.1
A timing signal for switching the transmitting / receiving unit 83 between the transmitting state and the receiving state is output in a cycle (sec). The transmission / reception unit 83 transmits the radio wave of the predetermined frequency to the field as described above when it is in the transmission state by the timing signal from the timing signal output means 82.

The radio wave transmitted to the field is received when the transmission / reception unit 83 is in the reception state, and the reception signal from the transmission / reception unit 83 is input to the determination unit 84. Normally, when the response signal output means 24A (explaining the case of assigning an individual code) does not exist in the electric field, that is, when the detected person 71 is not present at the entrance / exit, the transmitter / receiver section 83 responds as in the first embodiment. Since no signal is received, the determination unit 84 determines that the detected person 71 is not present at the entrance and exit, and the alarm output command signal is not output.

When the response signal output means 24A is present in the electric field, that is, when the detected person 71 is present at the entrance / exit, the response signal output means 24A attached to the detected person 71, for example, the clothes 72, is transmitted from the transmitting / receiving section 83. It receives the transmitted radio waves and sends a response signal with an individual code.

When the transmission / reception unit 83 is in the receiving state, when the response signal to which the individual code is added is received, the response signal and the individual code are received signals and the determination unit 84 is sent via the control unit 86.
Is input to When the received signal is input to the determination unit 84,
The reference signal stored in advance is compared with the received signal, and when they match, it is determined that the person to be detected 71 is present at the entrance, and the control unit 8
The individual code is output together with the alarm output command signal via 6.

When the alarm output command signal is input to the alarm output section 85, the alarm monitoring panel 25 of the monitoring center (monitoring room)
Based on the signal from the transmitter / receiver 81 of which entrance and exit, who is at the entrance and the like based on the individual code, the alarm monitoring board 25 displays. In addition, an external speaker, a lamp, or the like is appropriately activated.

If it is not necessary to identify the person to be detected, the response signal output means 24 shown in FIG. 2 is used. In this case, since the receiver 23 does not receive the individual code as in the first embodiment, the determination unit outputs only the alarm output command signal. Therefore, the monitoring center (monitoring room) cannot identify the person to be detected.

As described above, it is possible to obtain the same effect as that of the first embodiment, and it is possible to reduce the size by using the integrated transceiver 81.
