Embodiment
Hereinafter, embodiment involved in the present invention is illustrated referring to the drawings.Present embodiment does not limit this hair
It is bright.
(the 1st embodiment)
Fig. 1 is the figure of one of the composition for the electric car position detecting system for representing the 1st embodiment.1st embodiment
Electric car position detecting system possess multiple 1st label T1, multiple 2nd label T2, reader 11,12 (reference picture 2) and
Database 13 (reference picture 2).Multiple 1st label T1 are the labels that there is mutual identical to form.Multiple 2nd labels are with phase
The label that mutual identical is formed.On the other hand, the 1st label T1 and the 2nd label T2 have mutually different composition.
1st and the 2nd label T1, T2 is, for example, RFID label, can be times in active label or passive label
It is a kind of.But when the cost in view of system and setup cost etc., the 1st and the 2nd label T1, T2 is preferably need not
The passive label of power supply.
Multiple 1st label T1 are set along circuit 1, have mutually different identifier.Multiple 2nd label T2 are also along line
Road 1 is set, and has mutually different identifier.That is, multiple 1st and the 2nd label T1, T2 have intrinsic identifier respectively,
Label can be determined by reading the identifier.
The reader 11,12 that multiple 1st label T1 respectively there is electric car 10 described later to be carried being capable of reading identifier
The scope (following, also referred to as ID can read range) of (following, also referred to as ID).1st label T1 ID can read range be
1st scope D1.For example, the 1st scope D1 being capable of read range with about 2 meters of ID along circuit 1.Thus, reader 11,12
The 1st label T1 ID can be read in the range of each about 1 meter before and after from the 1st label T1 center along circuit 1.Change speech
It, reader 11,12 can along circuit 1 from the center from the 1st label T1 be about 1 meter nearby to from the 1st label T1
Read the 1st label T1 ID in the front that center is about 1 meter.
Multiple 2nd label T2 also have ID being capable of read range respectively.2nd label T2 ID can read range be the 2nd
Scope D2.2nd scope D2 is different from the 1st scope D1, narrower than the 1st scope D1.For example, the 2nd scope D2 has about along circuit 1
0.5 meter of ID being capable of read range.Thus, reader 11,12 can be each before and after from the 2nd label T2 center along circuit 1
The 2nd label T2 ID is read in the range of about 0.25 meter.In other words, reader 11,12 can be along circuit 1 from from the 2nd mark
Read the 2nd label in the front that the center nearby arrived from the 2nd label T2 that the center for signing T2 is about 0.25 meter is about 0.25 meter
T2 ID.
1st and the 2nd label T1, T2 is in the station that electric car 10 stops and the station periphery (following, also referred to collectively as car
Stand ST) configured along circuit 1.1st label T1 sets interval D ST1 configurations with the 1st, and the 2nd label T2 sets interval D ST2 with the 2nd
Configuration.That is, interval D ST1, two adjacent the 2nd labels are set at intervals of the 1st between the center of two adjacent the 1st label T1
Interval D ST2 is set at intervals of the 2nd between T2 center.
2nd sets interval D ST2 to set interval D ST1 different from the 1st, sets interval D ST1 narrow than the 1st.Thus, such as Fig. 1 institutes
Show, multiple 2nd label T2 can be configured between two adjacent the 1st label T1.In the present embodiment, three the 2nd labels
T2 is configured between two adjacent the 1st label T1.
For example, the 1st setting interval D ST1 is about 1.8 meters, the 2nd setting interval D ST2 is about 0.5 meter.In the situation
Under, the 1st sets interval D ST1 narrower than the 1st scope D1.Thus, as shown in figure 1, the ID of two adjacent the 1st label T1 can be read
Scope is taken to be repeated between the two the 1st label T1.In addition, the 2nd sets interval D ST2 and the 2nd scope D2 roughly equal.Thus,
As shown in figure 1, the ID of two adjacent the 2nd label T2 can read range substantially connect between the two the 2nd label T2.
In the present embodiment, three the 2nd label T2 are configured with relative to the 1st label T1.That is, the marks of the 1st label T1 and the 2nd
The ratio for signing T2 setting number is 1 to 3.The ratio is substantially certain along circuit 1 in ST AT STATION.For example, the 2nd label T2
Can substantially evenly it be configured between the 1st adjacent label T1.
Also, the 1st label T1 and the 2nd label T2 can also on the vertical direction of the bearing of trend relative to circuit 1 phase
Mutually configure with staggering.In this case, can be to set interval D ST2 throughout line without considering the 1st label T1 set location
The entirety on road 1 substantially evenly configures the 2nd label T2.That is, when from the side of circuit 1, the 2nd label T2 can also be set
In the position repeated with the 1st label T1.
As described above, the electric car position detecting system of present embodiment possesses the 1st and the 2nd label in ST AT STATION
T1, T2 both sides.Herein, electric car 10 does not only exist situation that is at low speed in ST AT STATION or stopping, and exists
Situation with high speed by station ST.For example, in the case where electric car 10 will stop in ST AT STATION, electric car 10 is with low speed
Traveling, therefore, reader 11,12 read the 2nd label T2 of remolding sensitivity relatively low (ID can read range narrow) ID, by
This can detect the position of electric car 10 exactly.On the other hand, electric car with high speed by station ST in the case of, set
It is difficult to ID of the detection sensitivity than the 2nd relatively low label T2 in the reader 11,12 of electric car 10, can not by the 2nd label T2
The position of electric car is detected exactly.Thus, in the electric car position detecting system of present embodiment, AT STATION in ST not only
Possess the 2nd label T2, be also equipped with the 1st label T1.Thus, electric car 10 with high speed by station ST in the case of, reader
11st, 12 read remolding sensitivities higher (ID can read range bigger) the 1st label T1 ID, thus, it is possible to detect exactly
The position of electric car 10.In this way, AT STATION in ST, electric car position detecting system possesses the double of the 1st and the 2nd label T1, T2
Side, no matter thus electric car 10 is at low speed or to run at high speed, can detect the position of electric car 10.
On the other hand, AT STATION and its beyond periphery, the 1st label T1 is configured with along circuit 1, but does not configure the 2nd label
T2.The reason is that AT STATION and its beyond periphery, electric car 10 need not set muting sensitivity to run at high speed
2nd label T2.In addition, same with the 1st label T1 in the ST of station, the 1st label T1 sets interval D ST1 to configure according to the 1st.
Fig. 2 is the figure of one of the composition for representing electric car 10.Electric car 10 possess antenna ANT1, ANT2, reader 11,
12nd, database 13, comparing section 14,15, operational part 16 and control unit 17.
Two antennas ANT1, ANT2 are the antennas of ID readings, are connected respectively with reader 11,12.Antenna ANT1, ANT2
With roughly the same gain characteristic.
Reader 11,12 is configured to, and obtains the ID from label T1 or T2 via antenna ANT1, ANT2 respectively.Read
Device 11,12 is formed with identical.
Database 13 preserves the ID and the 1st and the 2nd label T1, T2 that represent the 1st and the 2nd label T1, T2 setting position
The label position information of relation between putting.1st and the 2nd label T1, T2 ID be for each label it is intrinsic, with the 1st with
And the 2nd the respective set location of label T1, T2 correspond.Thus, if by the ID detected via antenna ANT1, ANT2 with
Label position information is compareed, then can distinguish the position of electric car 10.In addition, database 13 can also be by tag ID and car
The ST other information such as line number information of standing is established and associatedly preserved.
For example, Fig. 3 is the form of one for representing label position information.In label position information, the ID of each label with
The position of the label and station ST line number information establish association.ID numerical value, character, mark etc. represent.Label
Position dimension and longitude etc. represent.Station ST line number numerical value etc. represents.
Comparing section 14,15 shown in Fig. 2 is connected with reader 11,12 respectively, and is connected with database 13.Comparing section 14 will
ID from reader 11 is compared with the label position information from database 13.Thus, comparing section 14 is by ID and label
Positional information is compareed, it is determined that the position of the label with the ID.Different from comparing section 14, comparing section 15 will come from reader
12 ID is compared with the label position information from database 13.Thus, comparing section 15 enters ID and label position information
Row control, it is determined that the position of the label with the ID.
The comparison results of comparison of comparison results of comparison and comparing section 15 of the operational part 16 to comparing section 14 carries out logic fortune
Calculate.For example, operational part 16 is AND operation circuit, the logic product of the comparison results of comparison from comparing section 14 and 15 is carried out
Computing.In the case where the comparison results of comparison from comparing section 14 is consistent with the comparison results of comparison from comparing section 15, fortune
Positional information (dimension, longitude) of the calculation portion 16 to the output label of control unit 17.On the other hand, in the comparison pair from comparing section 14
According to result and the comparison results of comparison from comparing section 15 it is inconsistent in the case of, operational part 16 is not to the output label of control unit 17
Position (dimension, longitude) or to the output error signal of control unit 17.
Control unit 17 exports various control signals based on the positional information from operational part 16.For example, control unit 17 can
The velocity information of positional information from operational part 16 and electric car 10, braking information (gear) etc. are used together, and exported
Represent the control signal that electric car 10 stops.Now, electric car 10 can also permit the door of the vehicle of electric car 10 to open the door.Or
Person, can also AT STATION ST sides license gate enabling.Certainly, the control signal from control unit 17 can also be used for electricity
Other action controls of motor-car 10.
In this way, multiple readers 11,12 separately read the ID of label, operational part 16 via antenna ANT1, ANT2
Computing, the reliability of the position thus, it is possible to improve tag ID and label are carried out to its logic product.
Then, inquired into referring again to configurations of the Fig. 1 to the 1st label T1 and the 2nd label T2.In matching somebody with somebody shown in Fig. 1
In putting, the 1st label T1 setting interval D ST1 (for example, 1.8m) is less than the 1st scope D1 (for example, 2 meters).Thus, ID can be read
Scope is taken to be repeated in two adjacent the 1st label T1.Thus, reader 11,12 can be read under steam or in parking
Some the 1st label T1 ID.
2nd label T2 setting interval D ST2 (for example, 0.5m) is equal with the 2nd scope D2 (for example, 0.5 meter).But the
2 label T2 are not provided with the 1st label T1 set location.Thus, the ID of two adjacent the 2nd label T2 being capable of read range quilt
It is set as connecting between two adjacent the 1st label T1.Thus, reader 11,12 can be in two adjacent the 1st label T1
Between read the 2nd label T2 ID.Reader 11,12 by read the 2nd label T2 ID, thus, it is possible to detect reader 11,
12 which position between two adjacent the 1st label T1.In this way, by the 2nd label T2 to the sky between the 1st label T1
Between carry out interpolation, thus reader 11,12 can detect the position of electric car 10 exactly.
In addition, the 1st label T1 sets interval D ST1 configurations in the region beyond ST and station ST with the 1st AT STATION, because
This reader 11,12 can also detect the electronic of the region high speed traveling beyond the electric car by station ST, AT STATION ST
The position of car.
In this way, in the present embodiment, reader 11,12 can detect beyond ST AT STATION and station ST exactly
The position of the electric car of region high speed traveling, and the position of the electric car run at a low speed in ST AT STATION can be detected exactly
Put.
In the case where electric car 10 is run at high speed, reader 11,12 can be with the essence of the 1st scope D1 (for example, 2 meters)
The error (for example, ± 1 meter error) of degree, i.e. ± D1 × 1/2 determines the position of electric car.On the other hand, in electric car 10
In the case of running at a low speed, reader 11,12 can be with the precision of the 2nd scope D2 (for example, 0.5 meter), the i.e. mistake of ± D2 × 1/2
Poor (for example, ± 0.25 meter error) determines the position of electric car.
In this way, the electric car position detecting system of present embodiment, can be unrelated with the speed of electric car and examine exactly
Survey the position of electric car.In addition, the electric car position detecting system of present embodiment uses RFID (passive label etc.), therefore energy
Enough setup cost is suppressed must be than relatively low.
Reader 11,12 can be consistently detected the 1st label T1 either the 2nd label T2 both sides or the ID of either one.
Thus, the electric car position detecting system of present embodiment is, during being travelled on circuit 1 in, can be with as described above
Precision constantly detects the position of electric car 10.
(the 2nd embodiment)
Fig. 4 is the figure of one of the composition for the electric car position detecting system for representing the 2nd embodiment.In the 2nd embodiment party
In formula, the 2nd label T2 setting interval D ST2 is wider than the setting interval in the 1st embodiment.For example, the 2nd label T2's sets
It is about 1 meter to put interval D ST2.Other compositions of 2nd embodiment can be identical with the corresponding composition of the 1st embodiment.
By widely setting the 2nd label T2 setting interval D ST2, thus as shown in figure 4, two adjacent the 2nd labels
T2 ID can read range be separated from each other.Thus, between two adjacent the 1st label T1, in two adjacent the 2nd labels
T2 ID can produce area of space SP between read range.Area of space SP is the nothing between two adjacent the 1st label T1
Method reads the 2nd label T2 ID scope.
Reader 11,12 can not read the 2nd label T2 ID in area of space SP.But in this case, electric car
Position detecting system can learn that reader 11,12 is in area of space SP.For example, reader 11,12 detect some the 2nd
After label T2_1 ID, in the case of being not detected by with the 2nd label T2_2 of the 2nd label T2_1 adjoinings ID, it can obtain
Know that reader 11,12 is in the area of space SP being present between the two the 2nd label T2_1 and T2_2.That is, reading can be learnt
Device 11,12 is taken to be in 2nd label T2_1 corresponding with finally detected ID and be adjacent and be also not detected by ID the 2nd mark
Sign the area of space SP between T2_2.
Thus, the electric car position detecting system of the 2nd embodiment is that the ID even in the 2nd adjacent label T2 can
Existential Space region SP between read range, also electric car 10 can be detected with the precision with the 1st embodiment same degree
Position.That is, even if reducing the 2nd label T2 setting number as the 2nd embodiment, also it is able to maintain that the position of electric car 10
The accuracy of detection put.
(the 3rd embodiment)
Fig. 5 is the figure of one of the composition for the electric car position detecting system for representing the 3rd embodiment.3rd embodiment
Electric car position detecting system be also equipped with multiple 3rd label T3, the plurality of 3rd label T3 is set along the circuit 1 in the ST of station
Put and there is mutually different ID.
3rd label T3 be, for example, RFID label or active label or passive label it is any.But
If it is considered that the cost of system and setup cost etc., then preferably identical with the 1st and the 2nd label T1, T2, the 3rd label T3
For the passive label without power supply.
Multiple 3rd label T3 are set along circuit 1, and have mutually different identifier.That is, multiple 3rd label T3 points
Identifier that Ju You be not intrinsic, can determine label by reading the identifier.
3rd label T3 as ID can read range and there is the 3rd scope D3.3rd scope D3 is than the 1st and the 2nd model
Enclose the narrow scope of D1, D2.That is, the 3rd label T3 is the label that sensitivity is lower compared with the 1st and the 2nd label T1, T2.For example,
3rd label T3 being capable of read range with about 0.25 meter of ID along circuit 1.Thus, reader 11,12 can be from the 3rd
Label T3 center is along the ID that the 3rd label T3 is read in the range of each about 0.125 meter before and after circuit 1.In other words, reader
11st, 12 can be about 0.125 meter from the center from the 3rd label T3 along circuit 1 and be to the center from the 3rd label T3 nearby
Read the 3rd label T3 ID in about 0.125 meter of front.
3rd label T3 is configured in ST along circuit 1 AT STATION.3rd label T3 sets interval D ST3 configurations with the 3rd.That is, it is adjacent
Interval D ST3 is set at intervals of the 3rd between two the 3rd label T3 connect center.3rd sets interval D ST3 than the 1st label T1's
Set interval D ST1 and the 2nd label T2 setting interval D ST2 narrow.As shown in figure 5, multiple 3rd label T3 can be configured at neighbour
Between two the 2nd label T2 connect.In the present embodiment, two the 3rd label T3 be configured at two adjacent the 2nd label T2 it
Between.
For example, in the case where the 1st setting interval D ST1 is about 1.8 meters, the 2nd setting interval D ST2 is about 0.5 meter,
3rd sets interval D ST3 for example, it can be set to be about 0.25 meter, and make its center with the 1st and the 2nd set interval D ST1,
DST2 center is substantially uniform.That is, the 3rd label T3 can also be made substantially evenly to be configured between the 2nd adjacent label T2.
And then the 3rd label T3 can also be relative to the 1st and the 2nd label T1, T2 vertical with the bearing of trend of circuit 1
Direction on configure with mutually staggering.In this case, can without considering the 1st and the 2nd label T1, T2 set location
To set interval D ST3 substantially evenly to configure the 3rd label T3 throughout the entirety of circuit 1.That is, from the side of circuit 1
When, the 3rd label T3 can also be arranged at the position repeated with the 1st and the 2nd label T1, T2.
In this way, the electric car position detecting system of the 3rd embodiment possesses the 3rd label T3, the 3rd label T3 is as ID energy
Reach read range and there is the 3rd scope than the 1st and the 2nd narrow range.3rd label T3 setting interval D ST3 is than the 1st label
T1 setting interval D ST1 and the 2nd label T2 setting interval D SR2 are narrow.Thus, situation about being run at a low speed in electric car 10
Under, reader 11,12 can with the precision of the 3rd scope D3 (for example, 0.25 meter), i.e. ± D3 × 1/2 error (for example, ±
0.125 meter of error) determine the position of electric car.As a result, the 3rd embodiment can be detected more accurately in ST AT STATION
The position of the electric car run at a low speed.Other compositions of 3rd embodiment can be corresponding with the 1st or the 2nd embodiment
Form identical.Thus, the 3rd embodiment can also obtain the effect of the 1st or the 2nd embodiment.
