Further, the number of turns and the diameter of the coil may be appropriately changed depending on the detection target. As the conductor of the detection coil 21, Au (gold), Ag (silver), Cu (copper), Al (aluminum), or the like, which is a good conductor of a high-frequency signal, is used. By forming the coil 21 with a good conductor, sensitivity is improved and high-frequency power loss is reduced.

The oscillating unit 12 here comprises a PLL oscillator 49
However, the oscillation circuit itself may be another circuit as long as it is a known high-frequency oscillation circuit.
An oscillation circuit may be used. Note that the oscillation unit 12 is a CPU
The frequency is automatically changed by a command from the control unit 52. The frequency of the high-frequency signal output from the oscillating unit 12 is scanned, for example, in a range of 30 MHZ to 50 MHZ.

A PU 52 is provided, which converts an analog signal from the reflected wave sensor unit 13 into a digital signal, performs a logical process based on the reflected wave level and frequency, and performs a discrimination detection process such as vacancy, luggage, and sitting of a human body (adult, child). . The detection coil 21 of the human body sensor 1 of the above-described embodiment device is incorporated so as to be embedded in the seat of the passenger seat 65, as shown in FIGS. The circuit section 40 of the human body sensor 1 is installed in a seat 42 or a vehicle body 43.

The CPU2 human body sensor 1 _-1, 1 _-2, ... receives the human presence signal indicating the ride Karaokyaku, to calculate the travel distance from that point by running pulse,
The timer 3 is started, and the running time is counted. When customers are getting off the human body sensor 1 _-1, 1 _-2, since ... human presence signal is eliminated from, and stores the travel time and travel distance in the storage device 4, the travel time, to reset the running distance.

In the human body sensor 1 of this embodiment, a high-frequency signal is generated by the oscillating unit 12 and supplied to the sensor unit 11 via the transmission line 14. The high frequency signal of the oscillation unit 12 is
As described above, scanning is performed in the range of 30 MHZ to 50 MHZ. The high-frequency signal supplied to the sensor unit 11 is reflected by the sensor unit 11. In the sensor unit 11, the impedance of the sensor unit 11 differs due to the difference in the magnetic permeability and displacement current of the object depending on the object placed in the vicinity of the detection coil 21. Wave levels are different. The reflected wave is detected by the reflected wave sensor unit 13, and the control unit 15 discriminates and detects the vacant seat, the baggage, the human body, and the like based on the reflected wave level and the frequency.

In the passenger management apparatus shown in FIG. 1, when the oscillating unit 11 is oscillated, the reflected wave when the seat is vacant, when a child is seated, when an adult is seated, and when luggage or a metal plate is placed is placed. The characteristics of a, b, c, d, e, and f in FIG.
The characteristics shown in FIG. According to this, when vacant seats a and b and luggage are placed, the reflection coefficient is very small and Q is high at a certain frequency. When the human bodies c and d are seated, the reflection coefficient decreases at a certain frequency, but the degree of change is small and Q is small. Such differences in the frequency characteristics of the reflected waves are caused by differences in the magnetic permeability and displacement current of vacant seats (air), luggage, human bodies, and the like. In the case of metal,
The frequency is high as shown in e and f.

Therefore, as shown in FIG. 4, the reflection coefficient level detected by the reflected wave sensor unit 13 is equal to the reference value S.
Than _R, greater over the whole frequency range has been seated person, if the frequency of the reference value S _R smaller than the reflection coefficient in reverse, indicating that the vacancy or luggage is placed. The CPU 52 of the control unit 15 performs the above-described human body, vacant seat, and baggage discrimination processing.

In the passenger management apparatus of the embodiment shown in FIG. 1, when a passenger gets on a seat, the human body sensor 1 detects the passenger's getting on and sends a detection signal to the CPU 2. Upon receiving this signal, the CPU 2 starts the timer 3 and starts measuring the traveling distance by the traveling pulse. When customers are getting off the cab, the human body sensor 1 _-1, 1 _-2, the ... C
The signal indicating that there is a human body to PU2 disappears. Therefore, the counting of the timer 3 is stopped, and the counting of the traveling pulse is also stopped. Then, the running time and the running distance at that time are stored in the storage device 4. After that, the travel time and travel distance are reset to prepare for the next passenger ride. The above operation is repeated every time the customer gets on and off the vehicle.

FIG. 3 is a block diagram showing a taxi passenger management device according to another embodiment of the present invention. Human body sensor 1
_-1 , 1-2,... _Are the same as those in FIG.
2. In addition to the timer 3, a wireless device 5 and a microphone 6 are provided. In this embodiment, the traveling time and the traveling distance are transmitted to the management center by the wireless device 5 every time a passenger gets on and off the vehicle, that is, every time the vehicle actually gets off. In the Administration Center,
The data transmitted for each vehicle or each driver is filed.

FIG. 5 is a circuit diagram showing a taxi passenger management device according to another embodiment of the present invention. This passenger management device uses a human body sensor different from that shown in FIG. The human body sensor 1 used here includes an oscillating unit 70 that oscillates a high-frequency signal, a detection circuit 80 that detects a high-frequency signal output from the oscillating unit 70,
Control section 9 which receives the detection signal from the controller and determines the presence or absence of a human body
0.

The oscillating unit 70 includes a detection coil 71, a capacitor 72 connected in parallel to the detection coil 71, one end of which is grounded, a resistor 73 connected in parallel to the capacitor 72, and It has an FET 74 whose other end is connected to the gate, a series circuit of capacitors 75 and 76 connected between the gate of the FET 74 and the ground, and a resistor 77 connected in parallel with the capacitor 76.
Connection point of the capacitor 75 and 76 is connected to the drain of the FET 74, V _CC power source is connected to the source of the FET 74. The oscillating unit 70 is a Colpitts type LC oscillator, and does not need to be a novel oscillator itself. Thus, other well-known oscillators, such as a Hartley oscillator, may be used.

The oscillation frequency of the oscillation section 70 is desirably a high frequency signal of 10 MHZ or more.
When 1 is a single turn, the thickness of the number of cores is 1.2 mm and the diameter is 200 mm. The diameter of the coil 71 can be appropriately selected from about 150 mm to 300 mm. The capacitor 72 is 27 PF, and the resistor 73 is, for example, a variable resistor. The sensitivity can be adjusted by changing from 10 KΩ to 150 KΩ. Capacitors 75, 7
6 are each 47 PF. The resistance 77 is 470Ω. However, these constants are merely examples, and may be appropriately selected according to the frequency to be oscillated.

The detection unit 80 includes a capacitor 8 connected to one end of a drain of an FET 74 which is an output terminal of the oscillation unit 80.
1, a diode 82 having a cathode connected to the other end of the capacitor 81 and an anode grounded, and a diode 8 having an anode connected to the other end of the capacitor 81.
3 and a capacitor 84 connected between the cathode of the diode 83 and the ground, and a detection signal is output from the cathode of the diode 83.

The control unit 90 has an NPN transistor 91 to which the output signal of the detection unit 80 is applied via a resistor 92 to the base, the emitter is connected to ground, and the collector outputs a signal indicating the presence or absence of a human body. When the oscillating unit 70 is oscillated in a state where the human body sensor 1 is installed in a seat, the oscillation output characteristics when the seat is vacant, when a child is seated, when an adult is seated, and when luggage is placed. Has the same characteristics as those of a, b, c, d, e, and f in FIG. However, the reflected wave in FIG. 4 is a detection output. according to this,
Q when a and b vacant seats and luggage are placed is high,
When the human bodies c and d are seated, Q becomes small. That is, as shown in FIG. 6, A / B when B / C = 0.7.
Is inversely proportional to the Q value. Thus, when the Q value of FIG. 4 is obtained, the Q value decreases in the order of vacant seat>baggage>child> adult. Therefore, ON / OFF in the control unit 90
If the reference value is set between the luggage and the child, it is possible to detect whether or not the human body is seated.

Now, in the apparatus shown in FIG.
Assuming that a package other than a human body is placed, in these cases, the Q of the detection coil 71 is high, and therefore, the oscillation unit 70 oscillates and outputs a high-frequency signal (10 MHZ). This high-frequency signal is detected by the detector 80 and input to the transistor 91 of the controller 90. In this case, the input level to the transistor 91 is high and the transistor 9
1 turns ON. This ON is output as a signal indicating that there is no human body. Next, when a person sits on the seat 42, the Q of the detection coil 71 decreases due to the influence of the magnetic permeability of the human body.
Therefore, the oscillation of the oscillating unit 70 stops or weakens, and accordingly, the level of the high-frequency signal input to the detecting unit 80 becomes 0 or small, and accordingly, the detected signal from the detecting unit 80 is also low. Therefore, the transistor 91 is turned off.
Becomes This OFF is output as a signal having a human body.

When a signal indicating a presence of a human body is received from the human body sensor 1, the CPU 2 operates in the same manner as that shown in FIG.
FIG. 8 is a circuit diagram showing a passenger management apparatus for a taxi according to still another embodiment of the present invention, which employs the human body sensor used in FIG. 5 instead of the human body sensor of the apparatus shown in FIG.

FIG. 9 is a block diagram showing another example of a human body sensor that can be used in place of the human body sensor used in the embodiments of FIGS. The human body sensor 1 includes an oscillation unit 7
0, a detection unit 80, and a control unit 90,
This is the same as that of FIGS. When the human body and the object are discriminated and detected using the human body sensor 1 shown in FIGS. 5 and 8, the level of the metal object is closer to the human body level than that of the non-metallic object, and even the metal object may be detected as the human body. There is.

The human body sensor 1 shown in FIG. 9 is designed to prevent a malfunction due to a metal plate or the like, focusing on the oscillation frequency of a metal object. Therefore, this human body sensor 1
Has a filter circuit 101 and a detector 102 for high frequency. Now, when a human body on the seat is seated, the oscillation output of the oscillator 70 becomes small, it is detected by the detection unit 80, the signal level that is input to the control unit 90, for example, less than a reference value SR _1, therefore the control unit 90 outputs a human body presence signal. In the case of a human body or non-metal, the oscillation unit 70
Is cut off by the high-frequency filter 101 because the oscillation frequency is low. On the other hand, when a metal body is placed on the seat, the oscillation output of the oscillation unit 70 also decreases. However, the oscillation frequency in this case is higher than that of a human body or a nonmetallic object. The output of the oscillator 70, only high frequency components by the high frequency filter 101 is derived, is detected by the detection circuit 102, and although its output signal is input to the control unit 90, the level than, for example, the reference value SR ₁ large Therefore, the control unit 90 does not determine that a human body is present. Therefore, the metal body is not erroneously determined as a human body.

FIG. 10 is a block diagram showing still another example of a human body sensor which can be used in place of the human body sensor used in the apparatus shown in FIGS. This human body sensor 1
Also does not erroneously detect a metal body as a human body. 9 in that it includes an oscillation unit 70, a detection unit 80, and a control unit 90.
However, it is characterized by a frequency counter 103 that counts the output of the oscillating unit 70 and an amplification control unit 104 that controls the amplification of the amplifier 105 according to the frequency.

In the human body sensor 1, when the object is a human body or a non-metallic object, it is identified and detected by the same operation as that of the human body sensor described above. When the metal body is placed in the vicinity, the oscillation frequency of the oscillating unit 70 increases. The high-frequency oscillation output is counted by the frequency counter 103, and the higher the frequency, the more the amplification factor control unit 104 responds thereto.
Increase the gain of 05. Although the oscillation output of the oscillating unit 70 is lowered due to the presence of the metal body, the amplifier 10
Since the level is raised at 5, a high level input similar to that of a non-metallic object is applied to the control unit 90. Therefore, the metal body does not malfunction with the human body.

FIG. 11 is a block diagram showing still another example of a human body sensor which can be used in place of the human body sensor employed in the apparatus shown in FIGS. This human body sensor 1
Also, when the metal body is a human body, it does not malfunction. The human body sensor 1 also includes an oscillating unit 70, a detecting unit 80, a control unit 9
0 is provided. The control unit 90 includes a frequency counter 103 that counts the oscillation frequency of the oscillation unit 70.
It comprises an A / D converter 106 for converting the output of the detector 80 into a digital value, and a CPU 107.

In this human body sensor 1, in the case of a human body, the oscillation output of the oscillating unit 70 decreases, and the oscillation output is
0 and is detected by the CPU 1 via the A / D converter 106.
07. If it is a non-metallic material,
The output level of the oscillating unit 70 does not decrease, and the oscillating output is taken into the CPU 107 via the detecting unit 80 and the A / D converter 106. The CPU 107 compares the fetched signal level with a reference value to identify a human body and a nonmetallic object. In the case of a metal body, the oscillation output of the oscillation unit 70 decreases and the oscillation frequency increases. Frequency counter 10
Count value indicating a higher frequency in the CPU 107 by the frequency count of 3 will have taken, CPU 107 lowers the reference value, for example, the SR ₂ where predetermined. Thus, although the signal level is taken through the detection section 80, A / D converter 106 is reduced, the signal level because lowering the reference value to SR ₂ is still greater than the reference value. Therefore, the CPU 107 does not determine that the object is a human body, and does not output a signal indicating a human body. Therefore, the metal body is not erroneously detected as a human body.

In each of the above embodiments, the traveling amount of the actual vehicle stored in the storage device or transmitted to the management center by radio is the scanning time and the scanning distance, but the traveling time is the time at the time of getting on and off the vehicle. Alternatively, the fee may be a value to which a fee calculated from the travel time or the travel distance is added, or only the fee.

[0042]

According to the invention according to claims 1 to 8 of the present application, when the occupant is detected by a human body sensor provided on an empty seat, the travel time until getting off is obtained. Since the travel distance is stored or transmitted wirelessly to the management center, fraudulent declaration by a taxi driver can be prevented, and detailed business analysis can be performed using the travel data. In addition, since a human body sensor based on a change in magnetic permeability or displacement current is used, it is possible to separate a luggage and a human body seat with one sensor. Strong against electromagnetic field immunity. It is small. Not affected by weight. Even children can detect. Manufacturing cost is low. No need to touch human body. This has the effect.

According to the ninth to eleventh aspects of the present invention, in addition to the above-described effects, a human body and a metal can be reliably distinguished, and only when a human body is detected, the travel time and travel distance are stored or stored. It is possible to transmit and perform more accurate passenger management.
