Description

  The present invention is a wireless device that is mounted on a mobile body, transmits request information received from a ground radio device outside the mobile body to a mobile terminal, and transmits response information received from the mobile terminal to the ground radio device, The present invention relates to a wireless device operation method and a wireless device operation program.

  The Internet is commonly used not only in enterprises but also for personal use. In particular, recently, the use of the Internet by wireless communication is familiar due to the explosive spread of mobile phones, personal computers, smart phones that combine PDA (Personal Digital Assistant) functions, and portable game machines equipped with wireless LAN functions. It is becoming. In addition, public wireless LAN is being developed, and the Internet is being used not only indoors but also outdoors or in vehicles.

  One of the features of smartphones is that various applications can be downloaded and used. As a result, the user can use in accordance with the user's preference other than the standard functions such as voice call and mail. For example, a smartphone can be used as a car navigation receiver by downloading a car navigation application. As such a car navigation application, there is an application that can display various kinds of traffic information on a smartphone in real time by wirelessly communicating with a car navigation receiver mounted in a car as well as being used alone in an offline environment.

  However, as a problem of such wireless communication between an in-vehicle wireless device such as a car navigation receiver and a mobile terminal such as a smartphone, it is easily affected by electromagnetic noise, and temporarily compared with the case of wired communication. There is a high possibility that a severe communication disconnection will occur. In particular, since many electronic components are mounted in the moving body (vehicle or the like), it is easily affected by various electromagnetic noise sources. Further, for example, in midsummer or midwinter, it is easily affected by temperature, and communication disconnection due to deterioration of the reception characteristics of the electronic element can be considered.

  Since it is difficult to completely remove the electromagnetic noise, in order to reduce the influence of the temporary communication disconnection as described above to such an extent that the user does not feel uncomfortable, the in-vehicle wireless device side takes measures. There is a need. Specifically, for example, it is necessary to provide a buffer for saving communication data from communication disconnection to communication resumption so that the save data can be transmitted after communication is resumed.

On the other hand, in road-to-vehicle communication, in order to realize services aimed at traffic safety, alleviation of traffic congestion, and reduction of CO ₂ emissions, an intelligent road traffic system (Intelligent) that integrates roads (roadsides) and vehicles (vehicles) Transport System) (hereinafter referred to as ITS) is being developed.
There is an ITS spot service as a service using this system. In the ITS spot service, 5.8 GHz band DSRC (Dedicated Short Range Communication) that enables high-speed and large-capacity bidirectional communication is used.

  Users can acquire road traffic information and safe driving support information as images and audio by attaching DSRC communication devices (ITS spot compatible in-vehicle wireless devices and ITS spot compatible car navigation receivers or ITS spot compatible smartphone apps) to the vehicle. can do. In addition to using ETC (Electronic Toll Collection), you can also use cashless payment services (hereinafter referred to as EMV payment) in parking lots and drive-throughs, eliminating the hassle of paying cash in front of the gate. The vehicle can be passed through.

  In the EMV payment, data (hereinafter referred to as a wireless device confirmation request command) for inquiring whether or not to perform cashless payment as a payment method is sent from the roadside device to the in-vehicle wireless device corresponding to the ITS spot. The ITS spot compatible in-vehicle wireless device sends the data to the ITS spot compatible car navigation receiver or the ITS spot compatible smartphone application, and the ITS spot compatible car navigation receiver or the ITS spot compatible smartphone application displays a screen (button) for confirming the intention. The ITS spot-compatible car navigation receiver or the ITS spot-compatible smartphone application sends data including a button press result (hereinafter referred to as a wireless device confirmation response command) to the ITS spot-compatible in-vehicle wireless device, and the ITS spot-compatible in-vehicle wireless device sends the data to the roadside device. Send data. Thereby, the roadside machine can determine whether or not to execute the cashless settlement process. The wireless device confirmation request command includes an intention confirmation reception time. From this, the user is required to “within the reception time designated by the roadside device” and “to make a selection for intention confirmation”.

  In contrast to the fact that the user “selects for confirmation”, Patent Document 1 gives the user an opportunity to select the payment method again, and even if the user makes a mistake in selecting the payment method due to an operation error or the like. It is mentioned that the desired settlement method can be selected again.

JP 2009-98747 A (FIGS. 11 and 14, [0087] to [0095])

  However, in the above-mentioned Patent Document 1, consideration is not sufficiently given to the user making a selection for intention confirmation “within the reception time designated by the roadside device (terrestrial radio device)”. There are challenges.

  In the said patent document 1, the selection period is provided regarding selection of the payment method. However, if the in-vehicle communication is temporarily disconnected for a few seconds due to electromagnetic noise, etc., the reception of the wireless device confirmation request command by the ITS Spot compatible car navigation receiver or the ITS Spot compatible smartphone app is delayed. There is a problem that the period and the reception time of the roadside machine do not match. In particular, when the communication between the in-vehicle wireless device (wireless device) and the portable terminal uses wireless communication, it is necessary to consider the effect of temporary disconnection more than in the case of wired communication.

  In addition, when the user's selection period and the roadside machine reception time do not match, the roadside machine reception time may end depending on the decision making timing of the user. May not be available. As a result, there is a problem that the user is uncomfortable or confused.

  The present invention has been made to solve the above-described problems, and a wireless device and a method of operating the wireless device that allow a user to make a selection for confirmation within an acceptance time designated by a terrestrial wireless device It is another object of the present invention to obtain a wireless device operation program.

Embodiment 1 FIG.
In FIG. 1, a vehicle 100 moves outdoors. Wireless device 200 is attached to vehicle 100 and exchanges data with portable terminal 300 and exchanges data with roadside device 400 (ground radio device). For example, the transmission information of the roadside device 400 is sent to the wireless device 200, the wireless device 200 sends the transmission information to the mobile terminal 300, and the related information is displayed on the mobile terminal 300. It can be applied as The mobile terminal 300 exchanges data with the wireless device 200. The portable terminal 300 is assumed to be a general-purpose terminal such as a smartphone. However, as long as the portable terminal 300 can be connected to the wireless device 200 such as a tablet PC by wireless communication, application thereof is not hindered.

  The wireless device 200 and the mobile terminal 300 according to the first embodiment will be described as performing wireless communication conforming to the IEEE (The Institute of Electrical and Electronics Engineers, Inc.) 802.11 series. This does not preclude the application of wireless communication standards. In FIG. 1, the mobile terminal 300 is in the vehicle 100, but the mobile terminal 300 may be outside the vehicle 100 as long as it can communicate with the wireless device 200.

  The roadside device 400 exchanges data with the wireless device 200. The roadside machine 400 assumes a dedicated infrastructure facility outside the vehicle 100, but does not hinder the application of general-purpose facilities. In addition, although it is assumed that DSRC (Dedicated Short Range Communications) communication is performed between radio apparatus 200 and roadside device 400 in Embodiment 1, application of other radio communication standards is not hindered. The payment management apparatus 500 has a payment processing function and communicates with the roadside machine 400. Although it is assumed that TCP / IP communication via the Internet is performed between the roadside device 400 and the payment management device 500 in the first embodiment, application of other wireless communication standards is not hindered.

  In FIG. 2, the roadside communication processing unit 201 analyzes and shapes received data from the roadside device 400 received via the roadside wireless I / F 202 and transmits the data to the data control unit 205. In addition, the roadside communication processing unit 201 analyzes and shapes the data received from the data control unit 205 and transmits the data to the roadside device 400 via the roadside wireless I / F 202. In addition, description about the command and analysis / formatting method of each data is abbreviate | omitted in this invention. Arbitrary command analysis and shaping methods are possible under the applicable wireless communication standards. The roadside wireless I / F 202 communicates with the roadside device 400, establishes a connection (data link) between the roadside wireless I / Fs, and transfers data.

  The mobile terminal side communication processing unit 203 analyzes and shapes the data received from the mobile terminal 300 received via the mobile terminal side wireless I / F 204 and transmits the data to the data control unit 205. The mobile terminal side communication processing unit 203 analyzes and shapes the data received from the data control unit 205 and transmits the data to the mobile terminal 300 via the mobile terminal side wireless I / F 204. In addition, description about the command and analysis / formatting method of each data is abbreviate | omitted in this invention. Arbitrary commands and analysis / shaping methods are possible under the applicable wireless communication standard. The mobile terminal side wireless I / F 204 communicates with the mobile terminal 300, establishes a connection (data link) with the mobile terminal side wireless I / F 204, and transfers data.

  The data control unit 205 includes a data analysis unit 205A, a data relay unit 205B, a data reconstruction unit 205C, and a time management unit 205D. The data analysis unit 205A extracts parameters of data received from the roadside communication processing unit 201 and the mobile terminal side communication processing unit 203 and stores data in the data storage unit 207.

  The data storage unit 207 is extracted by the buffer 207A for relaying data from the roadside device 400 to the mobile terminal side, the buffer 207B for relaying data from the mobile terminal side to the roadside device 400, and the data analysis unit 205A. It has a confirmation seconds information memory 207C for storing parameters, and a time information memory 207D for storing both the reference time acquired by the time management unit 205D and the calculated difference time (time information).

  The data relay unit 205B relays the data by sending the data in the buffer 207A to the portable terminal side communication processing unit 203 and sending the data in the buffer 207B to the roadside communication processing unit 201. The data reconstruction unit 205C changes some parameters of the data in the buffers 207A and 207B. The time management unit 205D acquires and calculates time necessary for data control. In this document, the time is treated as the system time in the wireless device 200, but other time information may be used.

  The connection state monitoring unit 206 acquires a connection event of the mobile terminal side wireless I / F 204 and determines the connection state. In this document, when there is a change in the connection state of the mobile terminal-side wireless I / F 204, an event is notified to the connection state monitoring unit 206, but other methods may be used.

  In the description of the first embodiment, what is described as “to part” may be “to circuit” and “to device”, and “to step”, “to procedure”, and “to processing”. It may be. That is, what is described as “˜unit” may be realized by firmware. Alternatively, it may be realized only by software, only hardware such as an element, a device, a board, and wiring, or a combination of software and hardware, or further a combination of firmware.

  FIG. 3 is a diagram illustrating connection information held by the mobile terminal side wireless I / F 204 and the connection state monitoring unit 206 illustrated in FIG. 2 according to the first embodiment. The portable terminal-side wireless I / F 204 and the connection state monitoring unit 206 have different meanings of connection information to be held. The mobile terminal-side wireless I / F 204 has an instantaneous connection state (connection or disconnection), and notifies the connection state monitoring unit 206 whenever the connection state changes. The connection state monitoring unit 206 has three connection states (connected, disconnected, and being confirmed for connection) based on the connection information notified from the mobile terminal side wireless I / F 204. The connection state monitoring unit 206 does not immediately determine “disconnecting” even if a notification of “disconnect” is received from the mobile terminal-side wireless I / F 204, but determines that “connection is being confirmed”. ”Is regarded as a temporary disconnection due to noise or the like, and is“ connected ”. When no “connection” notification is received after a certain period of time, “disconnecting” is set for the first time.

  FIG. 4 is a diagram showing commands related to confirmation second information according to the first embodiment. The wireless device confirmation request command (request information) is a command notified from the roadside device 400 to the vehicle 100 in order to make the user select whether to use the service provided by the roadside device 400. The use / non-use can be selected within the time specified by the confirmation seconds information (time information) parameter. For example, if the specified time is 20 seconds, the user must decide whether to use or not within 20 seconds. The wireless device confirmation response command (response information) is a response command to the wireless device confirmation request. The user's service use selection result is transmitted to the roadside device 400. The selection results consist of three types: “use” indicating that the service is used, “not use” indicating that the service is not used, and “no input” indicating that there is no decision or no choice.

  FIG. 5 is a diagram illustrating an example of data reconstruction in the data reconstruction unit 205C used in the first embodiment. When the value of the confirmation seconds parameter before reconfiguration is “30 seconds” and this value is to be subtracted by 10 seconds, the value of the confirmation seconds parameter is changed to “20 seconds” and the checksum value is recalculated. .

Next, the operation will be described.
The wireless communication control process according to the first embodiment will be described with respect to a process for a wireless device confirmation request command that is data flowing from the roadside wireless I / F 202 to the mobile terminal side wireless I / F 204. Data received from the roadside wireless I / F 202 is received by the roadside communication processing unit 201 and temporarily stored in the buffer 207A of the data storage unit 207. If communication between the wireless device 200 and the portable terminal 300 is connected, the data relay unit 205B transmits data to the portable terminal side communication processing unit 203. If communication between the wireless device 200 and the portable terminal 300 is disconnected, the data reconstruction of the buffer 207A is performed by the data reconstruction unit 205C.

FIG. 6 is a flowchart illustrating an example of a process (operation) of the wireless device 200.
When the roadside communication processing unit 201 receives the wireless device confirmation request command from the roadside wireless I / F 202, the roadside communication processing unit 201 performs a data format check and sends the data to the data analysis unit 205A of the data control unit 205 (S100). Details of the format check are omitted. The data analysis unit 205A stores the received wireless device confirmation request command in the buffer 207A, reads the value of the confirmation seconds parameter, and stores it in the confirmation seconds information memory 207C (S101). Thereafter, the time management unit 205D acquires the current time (this is assumed to be t1), and stores it in the time information memory 207D with t1 as a reference time (S102). Thereafter, the data control unit 205 acquires the connection state from the connection state monitoring unit 206 (S103).

  If the connection state acquired in S103 is “disconnected” (NO in S104), the intention cannot be confirmed by the user, so the time management unit 205D determines the wireless device confirmation request command in the buffer 207A and the value in the time information memory 207D. (S105), the data relay unit 205B sends a wireless device confirmation response command with the confirmation result parameter “no input” to the roadside communication processing unit 201 (S106), and ends the process. If the connection state acquired in S103 is not “disconnected” (S104 YES), the time management unit 205D acquires the current time (this is t2), and the result of “t2-t1” is the difference time (time Information) is stored in the time information memory 207D (S107). If the difference time calculated in S107 is equal to or greater than the value stored in the confirmation seconds information memory 207C (YES in S108), the time management unit 205D has passed the time for confirming the intention to the user, and the time management unit 205D And the value of the time information memory 207D are deleted (S105), and the data relay unit 205B sends a wireless device confirmation response command whose confirmation result parameter is “no input” to the roadside communication processing unit 201 (S106), and ends the process. .

  If the difference time calculated in S107 is less than the value stored in the confirmation seconds information memory 207C (NO in S108), the connection state is reconfirmed from the connection state monitoring unit 206, and the result is other than “connected” (S109). Since the communication between the wireless device 200 and the portable terminal 300 may be cut off except during connection), the processing is performed again from S104. When S109 is connected (S109 is connected), the data reconfiguration unit 205C changes the confirmation seconds parameter of the wireless device confirmation request command based on the difference time stored in the time information memory 207D, and is shown in FIG. As described above, the wireless device confirmation request command is reconfigured (S110). The parameter changing method can be changed arbitrarily within a range that satisfies the command specifications. In the first embodiment, the effective value of the differential time is changed to be an integer part in seconds (for example, when the differential time is 0.5 seconds, the effective value is 0 seconds, so the parameter is not changed). Thereafter, the data relay unit 205B sends the wireless device confirmation request command reconfigured in S110 to the mobile terminal side communication processing unit 203 (S111).

  Thereafter, when the data relay unit 205B receives response data (ACK) indicating successful transmission of the wireless device confirmation request command from the mobile terminal side communication processing unit 203 (YES in S112), the process is terminated. When the response data (ACK) cannot be received (NO in S112), the process is performed again from S104 in order to perform the data retransmission process.

  7 to 10 are sequences showing an example of the flow of communication performed between the roadside device 400, the wireless device 200, and the mobile terminal 300 according to Embodiment 1 of the present invention. FIG. 7 is a diagram showing an example sequence when there is no error. When a wireless device confirmation request command (the value of the confirmation seconds parameter is 30 seconds) is sent from the roadside device 400 to the wireless device 200 (S200), data is relayed from the wireless device 200 to the portable terminal 300 (S201). . Since the effective value of the differential time is 0 seconds, it is assumed that there was no data change in S201. Since the response data is sent from the portable terminal 300 to the wireless device 200 (S202) and the response data is also sent within the confirmation seconds (S203), the wireless device 200 relays the data to the roadside device 400 (S204).

  FIG. 8 is a diagram illustrating an example sequence when communication between the wireless device 200 and the mobile terminal 300 is disconnected. A wireless device confirmation request command (the value of the confirmation second parameter is 30 seconds) is sent from the roadside device 400 to the wireless device 200 (S300), but communication between the wireless device 200 and the portable terminal 300 is disconnected. The wireless device 200 sends a wireless device confirmation response command with no confirmation result input to the roadside device 400 (S301).

  FIG. 9 is a diagram illustrating a sequence of an example in the case where a response is not returned from the portable terminal 300 even after the confirmation seconds. When a wireless device confirmation request command (the value of the confirmation seconds parameter is 30 seconds) is sent from the roadside device 400 to the wireless device 200 (S400), data is relayed from the wireless device 200 to the portable terminal 300 (S401). . Since the effective value of the difference time is 0 seconds, it is assumed that there was no data change in S401. Response data is sent from the portable terminal 300 to the wireless device 200 (S402). However, since the wireless device confirmation response command has not been sent from the portable terminal 300 to the wireless device 200 even after the confirmation seconds have elapsed, the wireless device 200 sends a wireless device confirmation response command with no confirmation result input to the roadside device 400 (S403).

  FIG. 10 is a diagram illustrating an example sequence in the case where the wireless device confirmation command is reconfigured and transmitted to the mobile terminal 300. When a wireless device confirmation request command (the value of the confirmation seconds parameter is 30 seconds) is sent from the roadside device 400 to the wireless device 200 (S500), data is relayed from the wireless device 200 to the portable terminal 300 (S501). . Since response data has not been sent from the portable terminal 300 to the wireless device 200, the wireless device 200 sends a wireless device confirmation request command again to the portable terminal 300 (S502). Since the effective value of the differential time is 10 seconds, the data is changed (changed from 30 seconds to 20 seconds) in S501. Since the response data is sent from the portable terminal 300 to the wireless device 200 (S503) and the response data is also sent within the confirmation seconds (S504), the wireless device 200 relays the data to the roadside device 400 (S505).

  As described above, according to the first embodiment, the data reconfiguration unit 205C reconfigures the wireless device confirmation request command (data change), so that appropriate data considering the connection state can be sent to the mobile terminal 300. . Therefore, it is possible to convey accurate information to the user. In addition, when communication between the wireless device 200 and the mobile terminal 300 is disconnected, the wireless device 200 can send a wireless device confirmation response command to the roadside device 400 without the user's intention, thereby enabling correct operation of the service. Become. Moreover, since there is no case in which the response confirmation waiting time on the roadside device side ends when the user shows the intention result, it is possible to reduce discomfort to the user.

  In the first embodiment, the determination is made based only on whether or not an ACK is received in S112, but the number of times of no reception may also be determined. For example, it is conceivable that the process proceeds to S104 when ACK reception fails four times in succession.

  In the first embodiment, the wireless device confirmation request command for 30 seconds is first transmitted from the roadside device 400 to the wireless device 200, and finally the wireless device confirmation response command is transmitted from the wireless device 200 to the roadside device 400. Thus, a series of sequences is completed, but not limited to this, while waiting for establishment of connection between the wireless device 200 and the mobile terminal 300, a confirmation request is newly extended from the roadside device 400 (for example, 60 seconds). There is a case where the command is transmitted to the wireless device 200. In this case, the wireless device 200 newly reconfigures data according to the data reconfiguration in the data reconfiguration unit illustrated in FIG. 5 according to the new confirmation seconds (for example, 60 seconds), and the mobile terminal 300 A wireless device confirmation request command (for example, 40 seconds) can be transmitted. As a result, the wireless device 200 can cope with the extension of the number of confirmation seconds, and can further reduce discomfort to the user.

  In the present invention, the embodiments can be appropriately modified and omitted within the scope of the invention.

  The present invention can be applied not only to a vehicle but also to other moving objects such as a ship and an aircraft.
