Detailed Description
The mode for carrying out the invention is explained in accordance with the drawings. In the drawings, the same or corresponding portions are denoted by the same reference numerals. Repeated explanation of this portion is appropriately simplified or omitted.
Embodiment mode 1
Fig. 1 is a configuration diagram of a traffic management system according to embodiment 1.
In the traffic management system of fig. 1, the traffic restriction device 1 is disposed at the boundary between the outside and the inside of the management area. The passage restricting device 1 has a pair of walls 1 a. The pair of walls 1a are disposed at intervals.
The door 2 is provided to the passage restricting device 1. The door 2 has a pair of door leaves 2 a. One of the pair of doors 2a is provided on one of the pair of walls 1 a. The other of the pair of doors 2a is provided on the other of the pair of walls 1 a.
The 1 st reading device 3 is provided to the passage restricting device 1 at one side of the door 2. Specifically, the 1 st reading device 3 is provided on one of the pair of walls 1a on the outside of the management area. The 2 nd reading device 4 is provided to the passage restricting device 1 on the other side in the door 2. Specifically, the 2 nd reading device 4 is provided outside the management area on the other of the pair of walls 1 a.
The tag 5 is carried by a user who manages the area. For example, the label 5 has at least one button 5 a.
The control device 6 is electrically connected to the passage restricting device 1, the 1 st reading device 3 and the 2 nd reading device 4.
The 1 st reader 3 always transmits the 1 st outgoing radio wave including the information of the 1 st response threshold and the information of the authentication start command. The 2 nd outgoing radio wave including the information of the 2 nd response threshold and the information of the authentication start command is always transmitted. The 1 st response threshold and the 2 nd response threshold are compared with the reception intensity value in the tag 5. When the reception intensity value is equal to or greater than the 1 st response threshold value or the 2 nd response threshold value, the tag 5 transmits a corresponding response radio wave.
When receiving the 1 st outgoing radio wave from the 1 st reader 3, the tag 5 transmits the 1 st response radio wave including tag information. When receiving the 2 nd outgoing radio wave from the 2 nd reader 4, the tag 5 transmits the 2 nd response radio wave including the tag information.
When receiving the 1 st response radio wave from the tag 5, the 1 st reader 3 transmits tag information included in the 1 st response radio wave to the controller 6. When receiving the 2 nd response wave from the tag 5, the 2 nd reader 4 transmits tag information included in the 2 nd response wave to the controller 6.
Then, the tag 5 measures the 1 st reception intensity value of the 1 st outgoing radio wave. The tag 5 transmits the 1 st response radio wave including the 1 st reception intensity value information for a predetermined period of time. The tag 5 measures the 2 nd reception intensity value of the 2 nd outgoing radio wave. The tag 5 transmits the 2 nd response radio wave including the information of the 2 nd reception intensity value for a predetermined period of time.
When receiving the 1 st response radio wave including the 1 st reception intensity value information of the 1 st transmission radio wave from the tag 5, the 1 st reader 3 transmits the 1 st reception intensity value information to the controller 6. When receiving the 2 nd response radio wave including the information of the 2 nd reception intensity value of the 2 nd transmission radio wave from the tag 5, the 2 nd reader 4 transmits the information of the 2 nd reception intensity value to the controller 6.
The control device 6 compares the tag information from the 1 st reading device 3 and the 2 nd reading device 4 with the tag information registered in advance. The control device 6 compares the information of the reception intensity values from the 1 st reading device 3 and the 2 nd reading device 4 with the information of the value corresponding to the authentication range set in advance.
The control device 6 performs authentication determination based on the comparison result of the tag information and the comparison result of the information of the reception intensity value. For example, when the tag information from the 1 st reader 3 and the 2 nd reader 4 matches the tag information registered in advance and the total value of the 1 st reception intensity value and the 2 nd reception intensity value is equal to or greater than the preset passage threshold value, the control device 6 authenticates the tag 5.
The control device 6 transmits the authentication determination result information to the passage restricting device 1, the 1 st reading device 3, and the 2 nd reading device 4.
The traffic restriction device 1 performs the unlocking operation when the authentication determination result information indicates that the authentication is performed. For example, the passage restricting device 1 unlocks the door 2. As a result, the door 2 is opened.
For example, the traffic management information setting device 7 is a personal computer. The traffic management information setting device 7 is electrically connected to the control device 6. For example, the traffic management information setting device 7 includes a reception intensity value acquisition unit 7a and a threshold setting unit 7 b.
The reception intensity value acquisition unit 7a is provided to be able to acquire information of the 1 st reception intensity value and information of the 2 nd reception intensity value via the control device 6. The threshold setting unit 7b is configured to be able to set the 1 st response threshold, the 2 nd response threshold, and the traffic threshold based on the 1 st reception intensity value information and the 2 nd reception intensity value information.
Next, an example of the operation of the traffic management system and the traffic management information setting device 7 when setting the 1 st response threshold, the 2 nd response threshold, and the traffic threshold will be described with reference to fig. 2.
Fig. 2 is a flowchart for explaining an example of operations of the traffic management system and the traffic management information setting device when setting the 1 st response threshold, the 2 nd response threshold, and the traffic threshold applied to the traffic management system in embodiment 1.
In step S1, the tag 5 measures the 1 st and 2 nd reception intensity values when the preset 1 st operation is performed. For example, the tag 5 measures the 1 st and 2 nd reception intensity values when the button 5a is pressed. Then, the operation of step S2 is performed. In step S2, the tag 5 transmits a 1 st response radio wave including the 1 st reception intensity value to the 1 st reader 3. The tag 5 transmits the 2 nd response radio wave including the 2 nd reception intensity value to the 2 nd reader 4.
Then, the operation of step S3 is performed. In step S3, the 1 st reader 3 determines whether or not the 1 st reception intensity value is a value corresponding to a predetermined authentication range. The 2 nd reader 4 determines whether or not the 2 nd reception intensity value is a value corresponding to a predetermined authentication range.
If at least one of the 1 st reception intensity value and the 2 nd reception intensity value is not a value corresponding to the authentication range set in advance in step S3, the operation is terminated without setting the 1 st response threshold, the 2 nd response threshold, and the traffic threshold.
If the 1 st reception intensity value and the 2 nd reception intensity value are values corresponding to the authentication range set in advance in step S3, the operation of step S4 is performed. In step S4, the 1 st reader 3 transmits the information of the 1 st reception intensity value to the traffic management information setting device 7 via the control device 6. The 2 nd reader 4 transmits the information of the 2 nd reception intensity value to the traffic management information setting device 7 via the control device 6.
Then, the operation of step S5 is performed. In step S5, the traffic management information setting device 7 sets the total value of the 1 st reception intensity value and the 2 nd reception intensity value as a reference intensity value.
Then, the operation of step S6 is performed. In step S6, the tag 5 measures the 1 st and 2 nd reception intensity values when the 2 nd operation set in advance is performed. For example, the tag 5 measures the 1 st and 2 nd reception intensity values when the button 5a is pressed. Then, the operation of step S7 is performed. In step S7, the tag 5 transmits a 1 st response radio wave including the 1 st reception intensity value to the 1 st reader 3. The tag 5 transmits the 2 nd response radio wave including the 2 nd reception intensity value to the 2 nd reader 4.
Then, the operation of step S8 is performed. In step S8, the 1 st reader 3 determines whether or not the 1 st reception intensity value is a value corresponding to a predetermined authentication range. The 2 nd reader 4 determines whether or not the 2 nd reception intensity value is a value corresponding to a predetermined authentication range.
If at least one of the 1 st reception intensity value and the 2 nd reception intensity value is not a value corresponding to the authentication range set in advance in step S8, the operation is terminated without setting the 1 st response threshold, the 2 nd response threshold, and the traffic threshold.
If the 1 st reception intensity value and the 2 nd reception intensity value are values corresponding to the authentication range set in advance in step S8, the operation of step S9 is performed. In step S9, the 1 st reader 3 transmits the information of the 1 st reception intensity value to the traffic management information setting device 7 via the control device 6. The 2 nd reader 4 transmits the information of the 2 nd reception intensity value to the traffic management information setting device 7 via the control device 6.
Then, the operation of step S10 is performed. In step S10, the traffic management information setting device 7 sets the 1 st reception intensity value as the 1 st response threshold. The traffic management information setting device 7 sets the 2 nd reception intensity value as the 2 nd response threshold value.
Then, the operation of step S11 is performed. In step S11, the traffic management information setting device 7 transmits the information of the 1 st response threshold to the 1 st reading device 3. The traffic management information setting means 7 transmits the information of the 2 nd response threshold to the 2 nd reading means 4. The traffic management information setting device 7 transmits the information of the reference intensity value to the control device 6.
Next, an example of the operation of the traffic management system when the user passes through the door 2 will be described with reference to fig. 3.
Fig. 3 is a flowchart for explaining an example of the operation of the traffic management system when a user passes through a door in the traffic management system according to embodiment 1.
In step S21, the 1 st reader 3 transmits the 1 st outgoing radio wave including the information of the 1 st response threshold and the information of the authentication start command. The 2 nd reader 4 transmits the 2 nd outgoing radio wave including the information of the 2 nd response threshold and the information of the authentication start command.
When the tag 5 approaches, the operation of step S22 is performed. In step S22, the 1 st reader 3 determines whether or not the tag 5 is present in the range corresponding to the 1 st response threshold value, based on the 1 st outgoing radio wave from the tag 5. The 2 nd reader 4 determines whether or not the tag 5 is present in the range corresponding to the 2 nd response threshold based on the 2 nd outgoing radio wave from the tag 5.
If the condition that the tag 5 is present in the range corresponding to the 1 st response threshold and the range corresponding to the 2 nd response threshold is not satisfied in step S22, the traffic management system ends the operation.
If the condition that the tag 5 is present in the range corresponding to the 1 st response threshold and the condition that the tag is present in the range corresponding to the 2 nd response threshold are satisfied in step S22, the operation of step S23 is performed. In step S23, the tag 5 continuously transmits the 1 st response radio wave containing the tag information and the 2 nd response radio wave containing the tag information.
Then, the operation of step S24 is performed. In step S24, the 1 st reading device 3 and the 2 nd reading device 4 transmit the tag information from the tag 5 to the control device 6.
Then, the operation of step S25 is performed. In step S25, the control device 6 determines whether or not the tag information from the 1 st reading device 3 and the 2 nd reading device 4 matches the tag information registered in advance.
In step S25, if the tag information from the 1 st reader 3 and the 2 nd reader 4 does not match the tag information registered in advance, the traffic management system ends the operation.
If the tag information from the 1 st reader 3 and the 2 nd reader 4 matches the tag information registered in advance in step S25, the operation of step S26 is performed. In step S26, the tag 5 transmits the 1 st response radio wave including the information of the 1 st reception intensity value and the 2 nd response radio wave including the 2 nd reception intensity value for a predetermined fixed time period.
Then, the operation of step S27 is performed. In step S27, the 1 st reader 3 transmits the information of the 1 st reception intensity value to the controller 6 at a predetermined fixed cycle. The 2 nd reader 4 transmits the information of the 2 nd reception intensity value to the controller 6 at a predetermined fixed cycle.
Then, the operation of step S28 is performed. In step S28, the control device 6 determines whether or not a condition that the total value of the 1 st reception intensity value and the 2 nd reception intensity value is equal to or greater than a value obtained by subtracting the preset tolerance α from the reference intensity value and equal to or less than a value obtained by adding the preset tolerance α to the reference line is satisfied.
If the condition that the total value of the 1 st reception intensity value and the 2 nd reception intensity value is equal to or greater than the value obtained by subtracting the preset allowable difference α from the reference intensity value and is equal to or less than the value obtained by adding the preset allowable difference α to the reference line is not satisfied in step S28, the traffic management system ends the operation.
If the condition that the total value of the 1 st and 2 nd reception intensity values is equal to or greater than the value obtained by subtracting the preset tolerance α from the reference intensity value and equal to or less than the value obtained by adding the preset tolerance α to the reference line is satisfied in step S28, the operation of step S29 is performed. In step S29, the control device 6 unlocks the door 2. Then, the traffic management system ends the action.
According to embodiment 1 described above, the 1 st response threshold value and the 2 nd response threshold value are set from the 1 st reception intensity value and the 2 nd reception intensity value measured when the tag 5 is operated. Therefore, the 1 st response threshold and the 2 nd response threshold can be appropriately and easily set.
For example, the 1 st response threshold may be set based on the 1 st reception intensity value measured when the tag 5 is operated in the region where the circle passing the position of the 2 nd reading device 4 with the position of the 1 st reading device 3 as the center and the circle passing the position of the 1 st reading device 3 with the position of the 2 nd reading device 4 as the center overlap on the horizontal projection plane. For example, the 2 nd response threshold value may be set based on the 2 nd reception intensity value measured when the tag 5 is operated in an area on the horizontal projection plane where a circle passing the position of the 2 nd reading device 4 with the position of the 1 st reading device 3 as the center overlaps with a circle passing the position of the 1 st reading device 3 with the position of the 2 nd reading device 4 as the center. In this case, the 1 st response threshold and the 2 nd response threshold can be set more appropriately.
The passage threshold is set based on the 1 st reception intensity value and the 2 nd reception intensity value measured when the tag 5 is operated. Therefore, the passage threshold value can be appropriately and easily set.
For example, the passage threshold may be set based on the 1 st reception intensity value and the 2 nd reception intensity value measured when the tag 5 is operated on the straight line connecting the 1 st reader 3 and the 2 nd reader 4 on the horizontal projection plane. In this case, the intention of the user to pass can be determined more appropriately by utilizing the property that the total value of the 1 st reception intensity value and the 2 nd reception intensity value on the straight line connecting the 1 st reading device 3 and the 2 nd reading device 4 is substantially constant.
The lower limit of the traffic threshold is set by subtracting a preset tolerance from the reference intensity value. Therefore, the intention of the user to pass can be determined more appropriately.
At this time, the threshold setting unit 7b may set not only the reference intensity value but also the traffic threshold. In this case, too, the intention of the user to pass can be determined more appropriately.
Further, the 1 st response threshold value and the 2 nd response threshold value are set to the 1 st reception intensity value and the 2 nd reception intensity value at the time of the 2 nd operation set in advance in the tag 5. Therefore, the 1 st response threshold and the 2 nd response threshold can be set more appropriately.
Further, when the total value of the 1 st reception intensity value and the 2 nd reception intensity value at the time of the 3 rd operation set in advance in the tag 5 is larger than the passing threshold value, the passing threshold value may be updated to the total value of the 1 st reception intensity value and the 2 nd reception intensity value. If the total value of the 1 st and 2 nd reception intensity values at the time of the 4 th operation set in advance in the tag 5 is smaller than the passing threshold, the passing threshold may be updated to the total value of the 1 st and 2 nd reception intensity values. In these cases, the traffic threshold value can be updated to an appropriate value according to the situation.
Further, when the 1 st reception intensity value at the time of the 5 th operation set in advance in the tag 5 is larger than the 1 st response threshold value, the 1 st response threshold value may be updated to the 1 st reception intensity value. When the 2 nd reception intensity value at the time of the 5 th operation set in advance in the tag 5 is larger than the 2 nd response threshold value, the 2 nd response threshold value may be updated to the 2 nd reception intensity value. If the 1 st reception intensity value obtained when the tag 5 has performed the preset 6 th operation is smaller than the 1 st response threshold value, the 1 st response threshold value may be updated to the 1 st reception intensity value. If the 2 nd reception intensity value obtained when the tag 5 has performed the preset 6 th operation is smaller than the 2 nd response threshold value, the 2 nd response threshold value may be updated to the 2 nd reception intensity value. In these cases, the 1 st response threshold and the 2 nd response threshold can be updated to appropriate values according to the situation.
Next, an example of the traffic management information setting device 7 will be described with reference to fig. 4.
Fig. 4 is a hardware configuration diagram of a traffic management information setting device applied to the traffic management system in embodiment 1.
Each function of the traffic management information setting device 7 can be realized by a processing circuit. For example, the processing circuit has at least one processor 8a and at least one memory 8 b. For example, the processing circuit has at least one dedicated hardware 9.
In the case where the processing circuit has at least one processor 8a and at least one memory 8b, the respective functions of the traffic management information setting device 7 are realized by software, firmware, or a combination of software and firmware. At least one of the software and the firmware is described as a program. At least one of the software and firmware is stored in the at least one memory 8 b. The at least one processor 8a reads out and executes the program stored in the at least one memory 8b, thereby realizing each function of the traffic management information setting device 7. The at least one processor 8a is also referred to as a central processing unit, a processing unit, an arithmetic unit, a microprocessor, a microcomputer, or a DSP. For example, the at least one memory 8b is a nonvolatile or volatile semiconductor memory such as a RAM, a ROM, a flash memory, an EPROM, an EEPROM, a magnetic disk, a flexible disk, an optical disk, a compact disk, a mini disk, a DVD, or the like.
In case the processing circuit has at least one dedicated hardware 9, the processing circuit is for example realized by a single circuit, a complex circuit, a programmed processor, a parallel programmed processor, an ASIC, an FPGA or a combination thereof. For example, each function of the traffic management information setting device 7 is realized by a processing circuit. For example, the functions of the traffic management information setting device 7 are realized by a processing circuit in a lump.
The functions of the traffic management information setting device 7 may be partially implemented by dedicated hardware 9 and the other parts may be implemented by software or firmware. For example, the function of the threshold setting unit 7b may be realized by a processing circuit as dedicated hardware 9, and the at least one processor 8a may realize a function other than the function of the threshold setting unit 7b by reading out and executing a program stored in the at least one memory 8 b.
In this way, the processing circuit realizes each function of the traffic management information setting device 7 by hardware 9, software, firmware, or a combination thereof.
Although not shown, the functions of the control device 6 may be realized by the same processing circuit as the processing circuit that realizes the functions of the traffic management information setting device 7.
