The wireless communication process refers to a series of processes as follows. That is, the OES terminal 33 detects the current hierarchy based on the acceleration detected based on the detected acceleration with the start of wireless communication. The OES terminal 33 refers to a series of flows for selecting the most appropriate base station based on the detected hierarchy and executing control for performing wireless communication based on the selected base station.

When the wireless communication process is executed, as shown in FIG. 3, in the CPU 111 of the OES terminal 33, the detection unit 141, the time measurement unit 142, the hierarchy detection unit 143, the base station selection unit 144, and the communication control Part 145 functions.
As one area of the storage unit 120, a base station information storage unit 151 is provided. Note that the base station information storage unit 151 is provided as an area of the storage unit 120, and may be provided as an area of the removable medium 131, for example.

  The detection unit 141 detects acceleration based on the triaxial acceleration data output from the triaxial acceleration sensor 116. The detection unit 141 supplies the detected acceleration to the time measuring unit 142.

  The base station selection unit 144 selects a base station 31 corresponding to the hierarchy detected by the hierarchy detection unit 143 among the plurality of base stations 31. Here, the base station 31 corresponding to the hierarchy refers to the base station 31 corresponding to the hierarchy previously associated with the electric field intensity from the base station 31, and specifically, the base stations 31 arranged in each hierarchy. Say.

  The base station information storage unit 151 includes various information files for managing the OES terminal 33 and the base station 31, and includes information on the base station 31 indicating the frequency band and base station ID of each base station 31. Is remembered.

FIG. 4 is a diagram for explaining an example of base station information stored in the base station information storage unit 151.
The base station information stored in the base station information storage unit 151 includes “hierarchy”, “base station ID”, and “frequency band”. Therefore, the structure of the base station information stored in the base station information storage unit 151 is not particularly limited as long as it shows such a relationship. In this embodiment, as shown in FIG. It has a structure.

  The “hierarchy” stored in the predetermined row is information indicating a hierarchy where the current OES terminal 33 is present among a plurality of hierarchies of the building. The “base station ID” stored in a predetermined row is information indicating a code for uniquely identifying each base station 31, and identifies the selected base station 31 when performing wireless communication processing described later. It is information for. The “frequency band” stored in a predetermined row is information indicating a frequency band used for wireless communication set for each base station 31.

Specifically, “1” is stored as the “base station ID” corresponding to the hierarchy “B3F”. Then, “a.aaa GHz” is stored as the “frequency band” corresponding to the “base station ID” “1”. Similarly, “2” is stored as the “base station ID” corresponding to the hierarchy “B2F”. Then, “b.bbbGHz” is stored as the “frequency band” corresponding to the “base station ID” “2”. That is, in this embodiment, a base station ID indicating the base station 31 arranged for each layer is associated with each layer. Each base station ID and frequency band correspond one-to-one.
In the present embodiment, the base station information of FIG. 2 is stored in the base station information storage unit 151, but is not limited to this, and is not limited to the RAM (not shown) or the removable media 131 of the OES terminal 33. It may be. The base station selection unit 144 supplies information on the selected base station 31 to the communication control unit 145.

FIG. 5 is a flowchart for explaining a series of wireless communication processing executed by the OES terminal 33 having the functional configuration of FIG.
When the wireless communication process is executed by the OES terminal, each functional block of FIG. 3 functions in the CPU 111, and the following process is executed. In other words, the operation subject of each process in the following steps corresponds to the CPU 111 in hardware. However, in order to facilitate understanding of the present invention, the processing of the following steps will be described on the assumption that each functional block functioning in the CPU 111 is an operation subject.
Hereinafter, the wireless communication process of the OES terminal 33 will be described with reference to the flowchart of FIG.

The user (employee of the restaurant) operates the input unit 118 of the OES terminal 33 to instruct the start of wireless communication by the OES terminal 33, and can input the level at which the user is currently located as an initial setting.
The wireless communication process is started in response to the wireless communication instruction by the user and the input of the current position, and the following process is executed.

In step S11, the communication control unit 145 selects a base station corresponding to the layer input as the initial setting, and starts wireless communication through the communication unit 121 based on the selected base station. Specifically, the communication control unit 145 refers to the base station information storage unit 151, selects and selects the base station ID corresponding to the layer input as the initial setting based on the base station information of FIG. The frequency band associated with the base station ID is determined. Then, the communication control unit 145 starts wireless communication based on the determined frequency band.
For example, when the current position level input by the user as the initial setting is “1F”, “4” is selected as the base station ID corresponding to the “1F” level based on the base station information of FIG. Is done. Then, the frequency band “d.ddddGHz” associated with the base station ID “4” is determined. Then, the communication control unit 145 starts wireless communication based on the determined frequency band “d.ddddGHz”.

  In step S <b> 12, the detection unit 141 starts detecting acceleration output from the triaxial acceleration sensor 116.

  In step S13, the detection unit 141 determines whether or not motion in the vertical direction is detected. In this process, it is determined whether or not the OES terminal 33 has moved in the vertical direction, that is, to any one of the upper and lower layers from the current layer. The determination as to whether or not the object has moved is satisfied when the vibration cycle obtained based on the X component of the triaxial acceleration data output from the triaxial acceleration sensor 116, that is, the vertical vibration cycle is a predetermined cycle. It is. Therefore, when the vertical vibration period obtained from the X component of the triaxial acceleration data is a predetermined period, when the vertical vibration period output from the triaxial acceleration sensor 116 is a predetermined period, The movement form of the OES terminal 33 is recognized as “movement”. If no movement in the vertical direction is detected, that is, if the OES terminal 33 has not yet started moving between tiers, it is determined NO in step S13, and the process returns to step S13. In other words, until the movement in the vertical direction is detected, the determination process in step S13 is repeatedly executed, and the wireless communication process enters a standby state. On the other hand, if a movement in the vertical direction is detected, that is, if it is detected that the OES terminal 33 has moved toward either the upper hierarchy or the lower hierarchy, YES is determined in step S13. Is determined, the process proceeds to step S14.

  In step S14, the time measuring unit 142 starts measuring time after the detection of the acceleration in the vertical direction by the detecting unit 141 is started in step S13.

  In step S15, the detection unit 141 determines whether or not the movement in the vertical direction has stopped. In this process, it is determined whether or not the movement has been stopped since the OES terminal 33 has started moving in the vertical direction, that is, one of the upper hierarchy and the lower hierarchy from the current hierarchy. The The determination as to whether or not the movement is stopped is satisfied when each component of the triaxial acceleration data output from the triaxial acceleration sensor 116 is substantially zero. Therefore, when each component of the triaxial acceleration data is substantially 0, the movement form of the OES terminal 33 is recognized as “stop”. If the stop of the movement in the vertical direction is not detected, that is, if the OES terminal 33 is still moving between tiers, it is determined as NO in Step S15, and the process returns to Step S15. That is, until the stop of the movement in the vertical direction is detected, the determination process of step S15 is repeatedly executed, and the wireless communication process enters a standby state. On the other hand, when the stop of the movement in the vertical direction is detected, that is, it is detected that the OES terminal 33 has stopped moving toward either the upper hierarchy or the lower hierarchy. In this case, it is determined as YES in Step S15, and the process proceeds to Step S16.

  In step S16, the hierarchy detection unit 143 detects the current hierarchy based on the acceleration detected in step S13 and the time when the time measurement was started in step S14. Specifically, the hierarchy detection unit 143 integrates the three-axis acceleration data sequentially output from the three-axis acceleration sensor 116, thereby detecting the vertical movement of the OES terminal 33 after the movement in the vertical direction is detected. Calculate the travel distance. Here, the movement distance refers to the distance from the point where the movement in the vertical direction is detected in step S13 to the current position of the OES terminal 33. The point where the movement in the vertical direction is detected is the time when the hierarchy detection unit 143 starts integration, in other words, the time when the integration is set to 0 in the initial setting or the time when the integration is reset to 0 after that. 33 positions. And the hierarchy detection part 143 detects the present hierarchy based on the calculated moving distance.

  In step S17, the base station selection unit 144 selects the corresponding base station 31 based on the hierarchy detected in step S16. Specifically, the base station selection unit 144 refers to the base station information storage unit 151 and selects a base station ID corresponding to the hierarchy of FIG. The base station selection unit 144 supplies the data of the selected base station ID to the communication control unit 145 as information on the base station 31.

  In step S18, the communication control unit 145 performs control for performing communication based on the base station 31 selected in step S17. Specifically, the communication control unit 145 refers to the base station information storage unit 151 and selects a frequency band corresponding to the base station ID in FIG. Then, the communication control unit 145 controls the communication unit 121 based on the selected frequency band and performs wireless communication with the base station 31.

  In step S19, the communication control unit 145 determines whether or not an instruction to end the wireless communication process has been received. If an end instruction has not been received, NO is determined in step S19, and the process returns to step S13. That is, the process from step S13 to step S19 is repeatedly executed until an instruction to end the wireless communication process is received. On the other hand, if an instruction to end the wireless communication process is received, it is determined as YES in step S19, and the wireless communication process ends.

As described above, the OES terminal 33 of this embodiment includes the detection unit 141, the base station selection unit 144, and the communication control unit 145.
The detection unit 141 detects the hierarchy where the OES terminal 33 is located.
The base station selection unit 144 selects a base station 31 corresponding to the hierarchy detected by the detection unit 141 among the plurality of base stations 31.
The communication control unit 145 executes control for performing wireless communication with the base station 31 selected by the base station selection unit 144.
In this case, based on the hierarchy where the OES terminal is currently located, the most appropriate base station can be selected for that hierarchy. Communication can be performed based on the selected base station. Therefore, in a restaurant having a store with a plurality of wireless base stations configured by a plurality of hierarchies, the optimum radio wave can always be used, so an inefficient search for finding an appropriate base station It is possible to reduce time and the number of retransmissions for performing communication a plurality of times. Thereby, it is possible to perform reliable wireless communication and reduce power consumption.

The OES terminal 33 may further include a detection unit 141 and a time measuring unit 142.
The detection unit 141 detects the acceleration output from the triaxial acceleration sensor 116.
The timer 142 measures a predetermined time after the detection of the acceleration by the detector 141 is started.
And the hierarchy detection part 143 may detect the hierarchy in which the OES terminal 33 is located based on the acceleration detected by the detection part 141, and the time measured by the time measuring part 142.
In this case, the hierarchy where the OES terminal 33 is located can be detected more accurately based on the acceleration detected by the detector 141 and the time measured by the timer 142.

In addition, the storage unit 120 (more specifically, the base station information storage unit 151) in which the electric field strengths from the plurality of base stations 31 and the hierarchies are associated in advance may be provided.
Then, the base station selection means may select the base station 31 arranged in a hierarchy corresponding to the electric field strength from the base station 31 with reference to the storage unit 120.
In this case, since base stations with high electric field strength in the hierarchy are stored in association with each other in advance, the optimum base station 31 in the hierarchy can be selected simply by referring to the storage unit 120. Accordingly, it is not necessary to separately measure the electric field strength, so that power consumption can be reduced and reliable wireless communication can be performed.

The OES terminal 33 according to the first embodiment of the present invention has been described above.
Next, the OES terminal 33 according to the second embodiment of the present invention will be described.

[Second Embodiment]
The OES terminal 33 according to the second embodiment of the present invention can have basically the same hardware configuration and functional configuration as the OES terminal 33 according to the first embodiment.
Therefore, FIG. 1 is also a block diagram showing a hardware configuration of the OES terminal 33 according to the second embodiment.

Furthermore, the wireless communication process executed by the OES terminal 33 according to the second embodiment is basically the same flow as the wireless communication process according to the first embodiment. Therefore, FIG. 5 is also a flowchart for explaining the flow of wireless communication processing according to the second embodiment.
However, in the second embodiment, the processing of steps S32 to S34 of the wireless communication processing is not the flowchart of FIG. 5 employed in the first embodiment but the flowchart of FIG.
FIG. 6 is a flowchart for explaining the flow of wireless communication processing according to the second embodiment executed by the OES terminal 33 of FIG. 1 having the functional configuration of FIG.
When the wireless communication process is executed by the OES terminal, each functional block of FIG. 3 functions in the CPU 111, and the following process is executed. In other words, the operation subject of each process in the following steps corresponds to the CPU 111 in hardware. However, in order to facilitate understanding of the present invention, the processing of the following steps will be described on the assumption that each functional block functioning in the CPU 111 is an operation subject.

In the wireless communication processing of FIG. 5 in the first embodiment described above, the current hierarchy is detected based on the acceleration detected by the three-axis acceleration sensor 116 and the time measured, whereas In the wireless communication processing of FIG. 6 in the second embodiment, the current level is detected based on the altitude detected by the altitude sensor. Specifically, the second embodiment is different from the first embodiment in that steps S32 to S34 are executed instead of steps S12 to S16.
Thus, hereinafter, such differences will be mainly described, and description of the coincident points will be omitted as appropriate.

  The wireless communication process is started in response to a wireless communication instruction from the user and an input of a hierarchy at the current position. In this case, the process of step S31 similar to step S11 in the first embodiment is executed.

  In step S <b> 32, the detection unit 141 starts detecting the altitude output from the altitude sensor 117.

  In step S33, the detection unit 141 determines whether or not motion in the vertical direction is detected. In this process, it is determined whether or not the OES terminal 33 has moved in the vertical direction, that is, to any one of the upper and lower layers from the current layer. Whether or not the vehicle has moved is determined based on whether the altitude data calculated from the altitude sensor 117 has increased or decreased from a predetermined threshold. Therefore, when the altitude output from the altitude sensor 117 increases, it is recognized that the altitude sensor 117 has moved to a higher level. On the other hand, when the altitude output from the altitude sensor 117 decreases, it is recognized that the altitude sensor 117 has moved to a lower level. If no movement in the vertical direction is detected, that is, if the OES terminal 33 has not yet started moving between tiers, it is determined NO in step S33, and the process returns to step S33. That is, until the movement in the vertical direction is detected, the determination process in step S33 is repeatedly executed, and the wireless communication process enters a standby state. On the other hand, if a movement in the vertical direction is detected, that is, if it is detected that the OES terminal 33 has moved toward either the upper hierarchy or the lower hierarchy, YES is determined in step S33. Is determined, the process proceeds to step S34.

In step S34, the hierarchy detecting unit 143 detects the current hierarchy based on the detected altitude. Specifically, information on a hierarchy associated with altitude data is stored in the storage unit 120 in advance. And the hierarchy detection part 143 detects the hierarchy corresponding to the detected height with reference to the memory | storage part 120 based on the information with which the hierarchy and the height were matched.
When this process ends, the processes of Step S35 to Step S37 similar to the processes of Step S17 to Step S19 in the first embodiment are executed.

As described above, the OES terminal 33 of the present embodiment further includes the detection unit 141 that detects the altitude output from the altitude sensor 117.
Then, the hierarchy detection unit 143 detects the hierarchy where the OES terminal 33 is located based on the altitude detected by the detection unit 141.
In this case, since the current altitude is directly detected by the altitude sensor 117 and the level where the current OES terminal 33 is located can be detected, the level where the OES terminal 33 is located can be detected more accurately.

The OES terminal 33 according to the second embodiment of the present invention has been described above.
Next, the OES terminal 33 according to the third embodiment of the present invention will be described.

[Third Embodiment]
The OES terminal 33 according to the third embodiment of the present invention can basically have the same hardware configuration as the OES terminal 33 according to the first embodiment.
Therefore, FIG. 1 is also a block diagram showing a hardware configuration of the OES terminal 33 according to the third embodiment.

  Furthermore, the OES terminal 33 according to the third embodiment of the present invention can basically have the same functional configuration as the OES terminal 33 according to the first embodiment. Therefore, FIG. 3 is also a functional block diagram showing a functional configuration of the OES terminal 33 according to the third embodiment. However, in the third embodiment, in the functional block diagram, the recognizing unit 241, the time measuring unit 242, the area detecting unit 243, and the base station selecting unit 244 are not functional configuration diagrams employed in the first embodiment. 7 functional block diagram is adopted. As described above, the OES terminal 33 performs radio communication with one base station 31 among the plurality of base stations 31 arranged in a plurality of different areas.

In the functional block diagram of FIG. 3 in the first embodiment described above, the hierarchy where the OES terminal 33 is located is detected and detected based on the acceleration detected by the detecting unit 141 and the time measured by the time measuring unit 142. In the functional block diagram of FIG. 7 in the third embodiment, the OES terminal is selected based on the movement form of the OES terminal 33 recognized by the recognition unit 241. The difference is that 33 detects the moved area and selects the base station 31 corresponding to the detected area. Specifically, in the third embodiment, instead of the detection unit 141, the time measurement unit 142, the hierarchy detection unit 143, and the base station selection unit 144 according to the first embodiment, a recognition unit 241, a time measurement unit 242, and an area detection unit 243 are used. The difference is that the processing is executed by the base station selection unit 244.
Thus, hereinafter, such differences will be mainly described, and description of the coincident points will be omitted as appropriate.

  FIG. 7 is a functional block diagram showing a functional configuration for executing the wireless communication processing of the third embodiment, among the functional configurations of the OES terminal 33 including such components.

When the wireless communication process according to the third embodiment is executed, as shown in FIG. 7, in the CPU 111 of the OES terminal 33, a recognition unit 241, a time measurement unit 242, an area detection unit 243, and a base station selection The unit 244 and the communication control unit 245 function.
As one area of the storage unit 120, a base station information storage unit 151 is provided. Note that the base station information storage unit 151 is provided as an area of the storage unit 120, and may be provided as an area of the removable medium 131, for example.

The recognition unit 241 recognizes the movement form of the OES terminal 33. Specifically, the recognition unit 241 detects acceleration based on the triaxial acceleration data output from the triaxial acceleration sensor 116, and recognizes the current movement form of the OES terminal 33 based on the detected acceleration. The recognition unit 241 acquires triaxial acceleration data output from the triaxial acceleration sensor 116 of the sensor unit 20.
The recognizing unit 241 obtains the vibration period based on the triaxial acceleration data, and detects the movement form of the OES terminal 33 mainly using the vibration period in the vertical direction (vibration period obtained from the X component).
A series of processes executed until the recognition unit 241 detects the movement form of the user in this way is hereinafter referred to as “state detection process”.

  Here, the types of user movement modes that can be detected by the state detection process are not particularly limited, but at least a plurality of types are necessary. Therefore, in the present embodiment, three types of movement modes, that is, a stopped state, a walking state, and a running state can be detected by the state detection process.

  When each component of the triaxial acceleration data is substantially 0, the condition that “the acceleration is not detected by the triaxial acceleration sensor 116” is satisfied, and the movement form of the user is recognized as the “stop state”.

  Similarly, when the vertical vibration cycle obtained from the X component of the triaxial acceleration data is approximately 2 Hz, the condition “the vertical vibration cycle is detected by the triaxial acceleration sensor 116 is 2 Hz” is satisfied. Thus, the movement form of the user is recognized as “walking state”.

  Similarly, if the vertical vibration period obtained from the X component of the triaxial acceleration data 20B is 2 Hz or more, the condition that “the vertical vibration period is detected by the triaxial acceleration sensor 116 to exceed 2 Hz”. Is satisfied, and the movement form of the user is recognized as the “running state”. The recognition unit 241 supplies the recognized movement form to the area detection unit 243.

  The timing unit 242 counts a predetermined time after the recognition unit 241 recognizes the movement form. The timer unit 242 supplies the time measured to the area detector 243.

  The area detection unit 243 detects the area where the OES terminal 33 is currently located based on the movement form recognized by the recognition unit 241 and the time measured by the time measuring unit 242. The area detection unit 243 supplies the detected current area information to the base station selection unit 244.

The base station selection unit 244 selects a base station 31 corresponding to the area detected by the area detection unit 243 among the plurality of base stations 31. Here, the base station 31 corresponding to the area refers to the base station 31 corresponding to the area corresponding to the electric field intensity from the base station 31, and specifically refers to the base stations 31 arranged in each area.
The base station selection unit 244 selects the base station 31 arranged in each area as the base station 31 corresponding to the area detected by the area detection unit 243, but is not limited thereto. For example, a plurality of areas may be associated with one base station. In this case, the base station 31 arranged in the area A is selected regardless of whether the area A or the area B is detected as the area detected by the area detection unit 243. That is, in this case, area A and area B are associated with the base station 31 arranged in area A.

  Furthermore, the base station information storage unit 151 of the OES terminal 33 according to the third embodiment of the present invention may take basically the same configuration as the base station information storage unit 151 of the OES terminal 33 according to the first embodiment. it can. Therefore, FIG. 4 is also the base station information stored in the base station information storage unit 151 of the OES terminal 33 according to the third embodiment. However, in the third embodiment, “area” information is stored instead of “hierarchy” information in the base station information. Therefore, the base station information storage unit 151 stores, as base station information, electric field strengths from a plurality of base stations 31 and areas in association with each other in advance. As a result of measuring the electric field strength in advance, the base station 31 having a high electric field strength in the area is stored in association with the area.

Furthermore, the wireless communication process executed by the OES terminal 33 according to the third embodiment is basically the same as the wireless communication process according to the first embodiment. Therefore, FIG. 5 is also a flowchart for explaining the flow of wireless communication processing according to the third embodiment.
However, in the third embodiment, the processing of steps S53 to S57 in the wireless communication processing is not the flowchart of FIG. 5 employed in the first embodiment but the flowchart of FIG.

FIG. 8 is a flowchart for explaining the flow of wireless communication processing according to the third embodiment executed by the OES terminal 33 of FIG. 1 having the functional configuration of FIG.
When the wireless communication process is executed by the OES terminal, each functional block of FIG. 7 functions in the CPU 111, and the following process is executed. In other words, the operation subject of each process in the following steps corresponds to the CPU 111 in hardware. However, in order to facilitate understanding of the present invention, the processing of the following steps will be described on the assumption that each functional block functioning in the CPU 111 is an operation subject.

In the wireless communication processing of FIG. 5 in the first embodiment described above, the current hierarchy is detected based on the acceleration detected by the three-axis acceleration sensor 116 and the time measured, but the third embodiment. In the wireless communication processing of FIG. 8 in the form, the difference is that the current area is detected based on the recognized movement form and the time measured. Specifically, the third embodiment is different from the first embodiment in that steps S53 to S57 are executed instead of steps S13 to S17.
Thus, hereinafter, such differences will be mainly described, and description of the coincident points will be omitted as appropriate.

  The wireless communication process is started in response to a wireless communication instruction from the user and an input of a hierarchy at the current position. In this case, the process of step S51 similar to step S11 in the first embodiment is executed.

  In step S53, the recognizing unit 241 determines whether or not the movement form has been recognized. In this process, it is determined whether or not the OES terminal 33 has recognized either a walking state or a traveling state. In this case, the recognition unit 241 also recognizes whether the movement is in the vertical direction or the horizontal direction. When neither the walking state nor the traveling state is recognized, that is, when the OES terminal 33 has not yet started moving between the areas, it is determined as NO in Step S53, and the process proceeds to Step S53. Returned to That is, the determination process of step S53 is repeatedly executed until the movement form of either the walking state or the running state is detected, and the wireless communication process enters a standby state. On the other hand, if any movement form is detected in the walking state or the running state, that is, if it is detected that the OES terminal 33 has moved toward any area, YES is determined in step S53. And the process proceeds to step S54.

  In step S54, the timekeeping unit 242 starts timekeeping after the recognition unit 241 starts recognizing one of the walking modes or the running state in step S53.

  In step S55, the recognizing unit 241 determines whether or not the movement form has been stopped. In this process, it is determined whether or not the movement has stopped after the OES terminal 33 starts moving to any area. If the movement form is not in a stopped state, that is, if the OES terminal 33 is still moving between areas, it is determined as NO in Step S55, and the process returns to Step S55. That is, until the stop state is recognized, the determination process of step S55 is repeatedly executed, and the wireless communication process enters a standby state. On the other hand, when the stop state is recognized, that is, when it is detected that the OES terminal 33 has stopped moving to any area, it is determined as YES in Step S55, and the process proceeds to Step S56. Proceed to

  In step S56, the area detection unit 243 detects the current area based on the movement form recognized in step S53 and the time when the time measurement was started in step S54. Specifically, the area detection unit 243 determines that the movement distance per unit time from the previously detected area is small when the recognized movement form is a walking state. Therefore, the current area that has been moved is detected based on the distance obtained by integrating the moving speed and the time measured in the walking state. On the other hand, when the recognized movement form is the running state, it is determined that the movement distance per unit time from the previously detected area is large. Therefore, the current area that has been moved is detected based on the distance obtained by integrating the moving speed and the time measured in the running state.

  In step S57, the base station selection unit 244 selects the corresponding base station 31 based on the area detected in step S56. Specifically, the base station selection unit 244 refers to the base station information storage unit 151 and selects a base station ID corresponding to the area of FIG. The base station selection unit 244 supplies the selected base station ID data to the communication control unit 245 as information on the base station 31. When this process ends, the same processes as steps S58 to S59 in steps S18 to S19 in the first embodiment are executed.

As described above, the OES terminal 33 according to the present embodiment includes the recognition unit 241, the area detection unit 243, the base station selection unit 244, and the communication control unit 245.
The recognition unit 241 recognizes the movement form of the OES terminal 33.
The area detection unit 243 detects the area where the OES terminal 33 has moved based on the movement form recognized by the recognition unit 241.
The base station selection unit 244 selects a base station 31 arranged in the area detected by the area detection unit 243 among the plurality of base stations 31.
The communication control unit 245 executes control for performing wireless communication with the base station selected by the base station selection unit 244.
In this case, based on the area where the current OES terminal is located, the most suitable base station for the area can be selected. Communication can be performed based on the selected base station. Therefore, an optimal radio wave can always be used in a restaurant or the like having a store including a plurality of wireless base stations 31 constituted by a plurality of areas. Thereby, inefficient search time for searching for an appropriate base station 31 can be eliminated, and the number of retransmissions for performing communication a plurality of times can be reduced. Thereby, it is possible to perform reliable wireless communication and reduce power consumption.

  Further, the recognition unit 241 of the OES terminal 33 recognizes the movement in the vertical direction from the reference position as the movement form of the OES terminal 33. In this case, even if the areas are arranged along the vertical direction for each layer, it is possible to accurately detect the area where the current OES terminal moved from the reference position or the like input as the initial setting is located.

  Further, the recognition unit 241 of the OES terminal 33 recognizes the movement in the horizontal direction from the reference position as the movement form of the OES terminal 33. In this case, even if the area is arranged so as to expand along the two-dimensional direction, the area where the current OES terminal moved from the reference position or the like input as the initial setting can be accurately detected. .

Further, the storage unit 120 (more specifically, the base station information storage unit 151) in which the electric field strengths from the plurality of base stations 31 are associated with the areas in advance may be provided.
The base station selection unit may select the base station 31 arranged in an area corresponding to the electric field strength from the base station 31 with reference to the storage unit 120.
In this case, since base stations with high electric field strength in the area are stored in advance in association with each other, the optimum base station 31 in the area can be selected simply by referring to the storage unit 120. Accordingly, it is not necessary to separately measure the electric field strength, so that power consumption can be reduced and reliable wireless communication can be performed.

  In addition, this invention is not limited to the above-mentioned embodiment, The deformation | transformation in the range which can achieve the objective of this invention, improvement, etc. are included in this invention.

In the above-described embodiment, the radio communication system 10 to which the present invention is applied has been described as transmitting and receiving by radio communication with n base stations arranged for each of n hierarchies, but is not particularly limited thereto. For example, as shown in FIG. 9, it is also possible to transmit and receive by wireless communication with m (m is an arbitrary integer value other than n) base stations arranged in every n layers. FIG. 9 is a diagram illustrating an example of base station information stored in the base station information storage unit. In the example of FIG. 9, one base station is associated with two layers.
That is, in the above-described embodiment, the base station selection unit 144 selects the base station 31 arranged in each layer as the base station 31 corresponding to the layer detected by the layer detection unit 143. I can't. For example, as shown in FIG. 9, a plurality of layers may be associated with one base station. In this case, the base station 31 arranged on the first floor is selected regardless of whether the first floor or the second floor is detected as the hierarchy detected by the hierarchy detection unit 143. That is, in this case, the first and second floors are associated with the base stations 31 arranged on the first floor.

  The detection unit 141 detects acceleration based on the triaxial acceleration data output from the triaxial acceleration sensor 116, but is not limited thereto. For example, the detection unit 141 may detect the altitude output from the altitude sensor 117.

  The hierarchy detection unit 143 detects which hierarchy the OES terminal 33 is on the basis of the acceleration detected by the detection unit 141 and the time measured by the timer unit 142, but is not limited thereto. For example, the level detection unit 143 may detect which level the OES terminal 33 is in based on the altitude detected by the detection unit 141.

Further, in the above-described embodiment, the wireless communication system 10 using the OES terminal 33 to which the present invention is applied is described as performing control to output order information of dishes received at a restaurant seat. However, it is not particularly limited to this.
For example, the present invention can be applied to a general wireless communication system that requires an order. Specifically, for example, the present invention is applicable to an order system for restaurants, amusement parks, hotels, factories, and the like.

The series of processes described above can be executed by hardware or can be executed by software.
In other words, the functional configuration of FIG. 3 is merely an example, and is not particularly limited. That is, it is sufficient if the OES terminal 33 has a function capable of executing the above-described series of processing as a whole, and what functional block is used to realize this function is not particularly limited to the example of FIG.
In addition, one functional block may be constituted by hardware alone, software alone, or a combination thereof.
