At first, with reference to Fig. 1 structure according to the radio communications system 1 of the embodiment of the invention is described.
As shown in Figure 1, this radio communications system 1 comprises hollow D structure thing (here for railway carriage) 2, is installed in a plurality of in the above-mentioned structure 2 and (is no less than four; Here be four) emitter (transmitter) 10-1 to 10-4, launch control unit (emission controlling unit) 11 and as the mobile phone 20 of the communicator (communication terminal) of carrying out radio communication.
In radio communications system 1, the whole zone in the railway carriage (being designated hereinafter simply as the compartment) 2 all is the management area that the operation of mobile phone (being designated hereinafter simply as terminal) 20 should be managed.The operation of restriction (here for stopping radio communication function) terminal 20 in the predetermined specific region R (be designated hereinafter simply as and use restricted area) of radio communications system 1 in the management area.
Among a plurality of emitter 10-1 to 10-4 (following when these a plurality of emitter 10-1 to 10-4 are not distinguished from each other abbreviate as it emitter 10) each is used to make the position probing radio wave (described with reference to Fig. 2 after a while) of the position (terminal location) that terminal 20 can sense terminals 20 to terminal 20 emissions.
Point out in passing, the position of terminal 20 by shown in Fig. 1 (z)=(0,0,0)] three-dimensional coordinate is represented for x, y with respect to the initial point Q[Q of the lower right-hand corner of this side that is set in compartment 2.In the following description, " position " expression is with respect to the three-dimensional coordinate of initial point Q.
Below, the data structure of the position probing radio wave of each emission from a plurality of emitters 10 is described with reference to Fig. 2.This position probing radio wave comprises the information of following type (a) to (f):
(a) conduct is used to specify the group number (HEX one numerical digit) of the information of management area (here in the compartment 2);
(b) be used to specify self device number (HEX one numerical digit) of (emitter 10);
(c) self position (launcher position of (emitter 10); HEX six numerical digits);
(d) the use restricted area R (HEX 12 numerical digits) of terminal 20 is used in restriction therein;
(e) delivery time of position probing radio wave (HEX six numerical digits); And
(f) verification and (HEX one numerical digit).
Point out that in passing (c) launcher position in is that (three-dimensional coordinate (x, y, z)), wherein x, y and z have same ratio with respect to the positional information of initial point Q in the management area.For example when x was " 1cm=1 ", then y and z also were " 1cm=1 ".
Here, the use restricted area R in (d) is limited by two summit R1 of the information of zone (use restricted area) R that is represented by dotted line among Fig. 1 as expression and the position of R2.
Because it is three-dimensional using restricted area R, so two summit R1 on the diagonal and R2 are indicated as the information that restricted area is used in expression, thereby terminal 20 can be discerned based on the position of summit R1 and R2 and uses restricted area R.
As shown in Figure 1, the emission of radio wave from a plurality of emitters 10 detected in launch control unit 11 control positions.As shown in Figure 3, launch control unit 11 has reference clock 12.
Preferably, holding wire 13-1 to 13-4 equal in length.Thus, playing this from launch control unit 11 emission launch requirements signals and delivery time requires signal and this delivery time to arrive each each required time period equalization a plurality of emitters 10.Therefore, playing emitter 10 transmitting sites that receive the launch requirements signal from launch control unit 11 emission launch requirements signals detects each required time period of radio wave and equates at whole a plurality of emitters 10.
Therefore, it all is impartial that the delivery time that launch control unit 11 is determined is located at whole a plurality of emitter 10-1 to 10-4 as the little error between the time of position probing radio wave with each the actual transmission delivery time in a plurality of emitter 10, and this makes mobile phone 20 sense terminals position accurately.

As mentioned above, line of departure 13-1 to 13-4 equal in length, thus emitter 10 transmitting sites detect the predetermined time interval (being 100ms here) that the interval of radio wave equals launch control unit 11 emission launch requirements signals.Thus, the terminal 20 that receives the position probing radio wave can stably be carried out terminal location detection processing to schedule at interval.
As shown in Figure 5, terminal 20 comprises receiving element 21, transmitter unit 22, detecting unit 23 and processing unit 26.
Receiving element 21 receives radio wave by the antenna (not shown), receives at least from each the position probing radio wave in a plurality of emitters 10.
Point out that in passing receiving element 21 can receive the radio wave of the normal process (calling out or receive electronic information) that is used for terminal 20.
When receiving element 21 received position probing radio wave from 10 emissions of a plurality of emitters, a plurality of (being four here) position probing radio wave that detecting unit 23 receives based on receiving element 21 detected the position (terminal location) of himself terminal.
When receiving element 21 received from any the position probing radio wave in a plurality of emitters 10, whether normally detecting unit 23 had received the position probing radio wave by utilizing verification in the position probing radio wave and [information (f)] to check.
Detecting unit 23 is then based on using restricted area R using the information (coordinate of summit R1 and R2) of restricted area R to calculate from the expression that comprises in the position probing radio wave of a plurality of emitters 10 any, and discerns this use restricted area R.
Detecting unit 23 comprises propagation time computing unit (computing unit) 24 and special clock 25.
When receiving element 21 receives the position probing radio wave (more specifically, when detecting unit 23 is confirmed normally to detect the position probing radio wave), 24 calculating of propagation time computing unit are played receiving element 21 from emitter 10 transmitting sites detection radio wave and are received the required propagation time section of position probing radio wave, that is, the position probing radio wave propagates into the required time period of terminal 20 from emitter 10.
Particularly, based on the delivery time [information (e)] of the position probing radio wave that comprises in the position probing radio wave and based on time of reception to the position probing radio wave of special clock 25, propagation time computing unit 24 deducts delivery time and comes calculating location to detect the propagation time section of radio wave from the time of reception.
When the position probing radio wave that receives from all emitter 10-1 to 10-4, and propagation time that propagation time computing unit 24 calculates all position probing radio waves during section, detecting unit 23 computing terminal positions.
Here suppose that the position probing radio velocity of wave propagation from a plurality of emitters 10 is c, be followed successively by the t that propagation time computing unit 24 calculates from the propagation time section of the position probing radio wave of four emitter 10-1 to 10-4

As mentioned above, detecting unit 23 will be found the solution four simultaneous equationss (1) to (4) based on from each the equation of information substitution of position probing radio wave in a plurality of emitters 10, thus the computing terminal device (x, y, z).
In (4), the time error Δ t between reference clock 12 and the special clock 25 is unknown at above equation (1).Detecting unit 23 is based on setting up four simultaneous equationss from the position probing radio wave of four emitter 10-1 to 10-4, with consider time error Δ t computing terminal position (x, y, z).Therefore, (x, y are very accurately z) to the terminal location that calculates.
Can to calculate accurate terminal location based on time error Δ t by detecting unit 23 (z), radio communications system 1 has four emitter 10-1 to 10-4 for x, y in order to make.Detecting unit 23 is found the solution four simultaneous equationss (1) to (4), thus the computing terminal position (x, y, z).
Processing unit 26 is based on the terminal location of detecting unit 23 detected terminals 20, according to the predictive mode of operation operation that is suitable for the management area.Processing unit 26 comprises determining unit 27, operational mode determining unit 28 and switch unit 29.
Determining unit 27 determines that detecting unit 23 detected terminal locations are whether in using restricted area R.Particularly, determining unit 27 is used the information [information (d)] of restricted area R based on the expression that comprises in the position probing radio wave from a plurality of emitters 10, (x, whether y is z) in the region R of two summit R1 and R2 appointment to determine the terminal location that detecting unit 23 calculates.
The result who determines that operational mode determining unit 28 is carried out according to determining unit 27 determines the predictive mode of operation that processing unit 26 should be carried out.When determining unit 27 is determined terminal location (x, y, z) in the time of in using restricted area R, operational mode determining unit 28 determines that the operator scheme that the radio communication function that uses receiving element 21 and transmitter unit 22 (especially, transmitter unit 22) is limited is the predictive mode of operation that processing unit 26 should be carried out.Here, stop to be confirmed as the limited operator scheme of radio communication function from the operator scheme of transmitter unit 22 output radio waves.
When determining unit 27 determines that (x, y z) are positioned at when using restricted area R in addition terminal location, and operational mode determining unit 28 determines that the not limited normal manipulation modes of radio communication function are predictive mode of operation that processing unit 26 should be carried out.
Below, come the step of operation that detecting unit 23 and processing unit 26 carried out to be described with reference to flow chart shown in Figure 6 (step S1 to S6).Each transmitting site in the emitter 10 detects radio wave (step of transmitting).When receiving element 21 receives position probing radio wave from these emitters 10 (step S1), detecting unit 23 confirms normally to receive the position probing radio wave by utilizing verification and [information (f)], and determines that based on the group number that comprises in each position probing radio wave [information (a)] and device number [information (b)] whether the position probing radio wave is four (step S2) that different emitter 10-1 to 10-4 receive from same group [being the group of a plurality of emitter 10-1 to 10-4 of comprising that management area (compartment 2) is interior] here.
That is, detecting unit 23 number determines whether four position probing radio waves receive from whole a plurality of emitter 10-1 to 10-4 based on group number and device.
When receiving element 21 does not also receive position probing radio wave from whole emitter 10-1 to 10-4 (the "No" route among the step S2), handle the wait state that being back to before the step S1.When receiving element 21 has received position probing radio wave from whole emitter 10-1 to 10-4 (the "Yes" route among the step S2), detecting unit 23 calculates terminal location (the step S3 of himself terminal by utilizing above-mentioned equation (1) to (4); Detect step).
That is, when confirming when whole emitter 10-1 to 10-4 receive position probing radio wave (being four position probing radio waves) here the calculating that detecting unit 23 is carried out the terminal location of terminal 20.
When detecting unit 23 calculates terminal location, in the processing unit 26 really order unit 27 use whether (step S4 in using restricted area R of terminal location that the information [information (d)] of restricted area R determines the terminal 20 that calculated based on the expression in four position probing radio waves any; Determining step).
When determining unit 27 determines that the terminal location of terminal 20 is using in the restricted area R (the "Yes" route among the step S4), operational mode determining unit 28 is determined the limited operator scheme (operator scheme determining step) of radio communication function.Switch unit 29 switches to determined operator scheme (here for stopping from transmitter unit 22 output radio waves) (step S5) with the operation of processing unit 26, and processing is back to the preceding wait state of step S1.
On the other hand, when determining unit 27 determines that the terminal location of terminal 20 is not using in the restricted area R (the "No" route among the step S4), operational mode determining unit 28 is determined operator scheme.Switch unit 29 switches to determined operator scheme (exporting the normal manipulation mode of radio waves here for transmitter unit 22) (step S6) with the operation of processing unit 26, and processing is back to the preceding wait state of step S1.
Point out that in passing if remain on before the processing of processing unit 26 in step S6 under the limited operator scheme of radio communication function, then the above processing among the step S6 is that operator scheme is switched to normal manipulation mode.When processing unit 26 remained on normal manipulation mode following time before this processing, then switch unit 29 does not switch operator scheme, and keeps operator scheme constant.
In radio communications system 1, a plurality of (being four here) emitter 10 that transmitting site detects radio wave is installed in compartment 2 (it is designated as the management area) according to the embodiment of the invention.When the detecting unit 23 of terminal 20 receives position probing radio wave from corresponding a plurality of emitters 10, detecting unit 23 comes the terminal location (testing process) of the terminal 20 in the management of computing zone based on a plurality of position probing radio waves that receive, and the processing unit 26 of terminal 20 is operated (operating process) according to the operator scheme that is suitable for terminal location.Thus, detecting unit 23 is the terminal location of sense terminals 20 (himself) accurately, and processing unit 26 can be operated definitely according to the desired operation mode that is suitable for terminal location.
Promptly, according to the embodiment of the invention, because radio communications system 1 has a plurality of emitters 10 in the management area, so can avoid occurring following situation: because radio wave can't arrive, therefore can't detect the terminal location of terminal 20, for example just as disclosed technology in the above-identified patent document 1.On the contrary, detecting unit 23 is the sense terminals position definitely, can carry out management (restriction) to the operation of the processing unit 26 of terminal 20 definitely based on this terminal location thus.
In addition, processing unit 26 can be operated definitely according to the predictive mode of operation that is suitable for detecting unit 23 detected terminal locations.That is, can set the use restricted area R (wherein operating limited) of management area accurately.
According to this radio communications system 1, because detecting unit 23 detects the three-dimensional position that belongs to four emitters 10, so can not only consider the plane but also can consider to set under the situation highly and use restricted area R.When the structure that this radio communications system 1 is applied to such as building etc., can for example under the situation of the floor of considering building, in each layer, set the use restricted area.
In a plurality of emitters 10 each is all launched the radio wave of delivery time of expression launcher position of emitter and position probing radio wave as the position probing radio wave, detecting unit 23 based in a plurality of emitters 10 each launcher position and come the sense terminals position based on the propagation time section of delivery time.Therefore, detecting unit 23 can be definitely and sense terminals position accurately.
