Then, the operator uses the input device 27 to input settings related to the Internet 14, input identification information, and the like to perform initial setting of the signage 13.

In the initial setting of the signage 13, the controller 30 executes the initial setting process shown in FIG. First, when the power is turned on, the controller 30 determines whether or not "OFF" is set in the initial setting flag. The initial setting flag is a flag whose initial value is "OFF" and which is set to "ON" when the initial setting process is completed. The controller 30 may determine whether or not the identification information is stored in the memory 32, instead of determining whether or not the initial setting flag is "OFF". That is, the controller 30 determines whether or not the initial setting of the signage 13 has been completed in the process of step S11.

When the controller 30 determines that "OFF" is not set in the initial setting flag (S11: No), it determines that the initial setting has been completed, and ends the initial setting process. On the other hand, when the controller 30 determines that the initial setting flag is set to "OFF" (S11: Yes), it determines that the initial setting has not been completed, and executes the processes after step S12.

First, the controller 30 waits until the identification information is input (S12: No). When the controller 30 determines that the identification information has been input from the input device 27 (S12: Yes), the controller 30 stores the input identification information in the memory 32 (S13). The process of step S13 for storing the identification information in the memory 32 is an example of the “identification information acquisition process” of the present invention.

The controller 30 may acquire the identification information by a method other than the method input from the input device 27. For example, the signage 13 is provided with a slot into which a portable storage medium such as a USB (registered trademark) memory can be installed. The identification information is stored in advance in the portable storage medium. The controller 30 reads and acquires the identification information from the portable storage medium. The controller 30 may acquire the identification information by other methods in addition to the acquisition of the identification information using the input device 27 or the portable storage medium.

The controller 30 executes a process of acquiring the first URL after the execution of step S13, before the execution of step S12, or in parallel with the processes of steps S12 and S13. Specifically, the controller 30 waits until the first URL is input (S14: No). When the controller 30 determines that the first URL has been input from the input device 27 (S14: Yes), the controller 30 stores the input first URL in the memory 32 (S15). The process of step S15 for storing the first URL in the memory 32 is an example of the “address acquisition process” of the present invention. Since the traffic information server 11 is used regardless of the type of transportation such as a bus, train, or aircraft, the first URL disclosed by the traffic information server 11 is stored in the memory 32 before the signage 13 is installed at the bus stop. It may be stored in advance. In that case, the controller 30 acquires the first URL by reading the first URL from the memory 32.

Next, the controller 30 acquires the setup instruction (S16). The setup instruction is information instructing execution of acquisition of route information indicating the route of the bus 15 and departure time information indicating the departure time of the bus. The operator inputs the setup instruction to the controller 30 using, for example, the input device 27 or the above-mentioned portable storage medium. The controller 30 executes the processes after step S17 in response to the input of the setup instruction. The controller 30 may acquire the identification information as the acquisition of the setup instruction. That is, the controller 30 executes the processes after S17 in response to the acquisition of the identification information. The process of S16 for acquiring the setup instruction and the process of step S13 for acquiring the identification information are examples of the “setup instruction acquisition process” of the present invention.

The controller 30 generates a request in response to the acquisition of the setup instruction (S17). The request includes a first URL as a transmission destination, a communication address indicating the transmission source, type information indicating the type of transportation, installation position information, and a predetermined request. That is, the request is transmitted to the traffic information server 11 that publishes the first URL. The request is generated according to a communication protocol such as HTTP (HyperText Transfer Protocol) or HTTPs (HyperText Transfer Protocol over transport layer security).

The type information is information indicating the type of transportation such as a bus, a train, and an aircraft. The type information is stored in the memory 32 in advance. When the signage 13 is commonly used for buses, trains, aircraft, and the like, the type information is selected by the operator using the input device 27 and the like. The controller 30 includes the type information selected by the operator in the request.

The installation position information is information corresponding to the identification information stored in the memory 32, and is information that allows the traffic information server 11 to identify the location of the bus stop. If the traffic information server 11 can identify the location of the bus stop by the address, place name, or bus stop name, the controller 30 includes the identification information as the installation location information in the request. If the traffic information server 11 cannot specify the position by the place name, the stop name, or the stop number, the controller 30 specifies the installation position information according to the identification information as the information that the traffic information server 11 can specify the position. For example, a correspondence table in which the identification information and the address (installation position information) are associated with each other is stored in the memory 32 in advance. The controller 30 reads the address corresponding to the identification information read from the memory 32 from the memory 32 and acquires it as the installation position information. It is desirable that the information that allows the traffic information server 11 to identify the location of the bus stop is used as the identification information so that the identification information can be included in the request as it is as the installation position information.

The predetermined request included in the request is a request to return the route information indicating the route of the bus 15 stopped at the stop indicated by the installation position information, and the departure time information indicating the departure time of the bus at the stop. It is a request for that. Specifically, the controller 30 generates a request including a command requesting that the route information be returned and a command requesting that the departure time be returned. The command is stored in the memory 32 in advance.

The command requesting that the route information be returned and the command requesting that the departure time be returned include the above-mentioned type information and installation position information as incidental information. That is, the command requesting the return of the route information is to return the route information of the route including the stop indicated by the installation position information which is the incidental information in the transportation system (bus) indicated by the type information which is the incidental information. Request. In addition, the command requesting that the departure time information be returned is the departure time information indicating the departure time of the bus at the stop indicated by the installation position information which is the incidental information in the transportation system (bus) indicated by the type information which is the incidental information. Request to reply.

The command requesting that the route information be returned and the command requesting that the departure time be returned may be regarded as one command. Further, as long as the traffic information server 11 can be decrypted, the request may include a request other than the request using the command. Furthermore, the controller 30 may generate two requests, a request including a command requesting that the route information be returned and a request including a command requesting that the departure time be returned. Whether the controller 30 generates one request or a plurality of requests depends on the data structure of the generated request. The request is composed of, for example, an area for storing a transmission number for specifying the request, an area for storing a command, an area for storing incidental information, and the like. If the area for storing commands can include a plurality of commands, the controller 30 generates one request including the plurality of commands.

The departure time information is an example of the "scheduled operation time information" of the present invention. The scheduled operation time information may include not only the departure time but also the estimated arrival time information indicating the estimated arrival time when the bus 15 arrives at the bus stop, the stop time information indicating the stop time at the bus stop, and the like. That is, the request generated in step S17 may include a request for returning the departure time information, the estimated arrival time information, and the stop time information.

Further, the process of step S18 for transmitting a request including a command for requesting a return of route information is an example of the "route information request process" of the present invention. The process of step S18 for transmitting a request including a command for requesting a return of departure time information is an example of the "time information request process" of the present invention.

The controller 30 transmits the generated request to the Internet 14 through the communication module 23 (S18). Then, the controller 30 waits until the response to the transmitted request is received (S19: No). If the controller 30 determines that the response could not be received even after a predetermined time has elapsed since the request was transmitted, the controller 30 retransmits the request.

On the other hand, although not shown in the flowchart, the request transmitted by the controller 30 is received by the traffic information server 11. The traffic information server 11 executes a command included in the received request. Specifically, the traffic information server 11 reads out from the traffic database the route information and the departure time information of the route including the stop indicated by the installation position information in the transportation system (bus) indicated by the type information included in the command. Generate a response that includes traffic information. Then, the traffic information server 11 returns the generated response to the communication address included in the received request. The traffic information to be read is information that the management server 12 transmits in advance to the traffic information server 11 and is stored in the traffic database of the traffic information server 11. The traffic information server 11 generates a response according to the communication protocol of HTTP or HTTPS. That is, the response returned by the traffic information server 11 is received by the signage 13 over the firewall generated by the router.

When the controller 30 determines that the response has been received (S19: Yes), the controller 30 stores the route information and the departure time information included in the received response in the memory 32 (S20). The process of step S19: Yes for receiving the response including the route information is an example of the "route information reception process" of the present invention. The process of step S19: Yes for receiving the response including the departure time information is an example of the “time information reception process” of the present invention. The process of step S20 for storing the route information and the departure time information in the memory 32 is an example of the "memory process" of the present invention.

The controller 30 sets "ON" in the initial setting flag according to the fact that the route information and the departure time information are stored in the memory 32 (S21), and ends the initial setting process. Although not shown in the flowchart, the controller 30 may notify that the initial setting process has been completed in response to the completion of the initial setting process. Specifically, the controller 30 sends an e-mail indicating that the initial setting process has been completed to the e-mail address stored in advance in the memory 32. The e-mail address is, for example, the e-mail address of a person in charge of a bus company or the like.

Next, the first display control process in which the controller 30 displays the route information, the departure time information, the position information of the bus 15, and the delay information of the bus on the display 21 of the display device 20 will be described.

First, as shown in FIG. 5, the controller 30 determines whether or not the display start time has come (S30). Specifically, the controller 30 determines whether or not the time indicated by the date and time information input from the clock module 25 is the departure time of the first bus 15 stored in the memory 32 or a predetermined time before the departure time. To judge. Instead of providing the clock module 25 in the signage 13, the controller 30 may periodically acquire the date and time information through the Internet 14.

The controller 30 waits until the display start time is reached (S30: No). Then, when the controller 30 determines that the display start time has come (S30: Yes), the controller 30 generates a request (S31). The request includes a first URL, a communication address, type information, installation position information, and a predetermined request. That is, the controller 30 generates a request for a reply to the traffic information server 11.

The predetermined request is a request to return the position information of the bus 15 traveling on the route including the stop indicated by the installation position information, and a request to return the delay information. The delay information is at least one of information indicating that the bus is behind schedule or information indicating the delay time.

The controller 30 generates a request including a command requesting that the position information be returned and a command requesting that the delay information be returned. The command is stored in the memory 32 in advance. The command requesting that the position information be returned and the command requesting that the delay information be returned include the type information and the installation position information as incidental information. That is, the command requesting the return of the position information is the current position of the bus 15 traveling on the route including the stop indicated by the installation position information which is the incidental information in the transportation system (bus) indicated by the type information which is the incidental information. Request to reply. Further, the command requesting the return of the delay information is the delay information of the bus 15 traveling on the route including the stop indicated by the installation position information which is the incidental information in the transportation (bus) indicated by the type information which is the incidental information. Request to reply.

The command requesting that the position information be returned and the command requesting that the delay information be returned may be regarded as one command. Further, as long as the traffic information server 11 can be decrypted, the request may include a request other than the request using the command. Furthermore, the controller 30 may generate two requests, a request including a command requesting that the position information be returned and a request including a command requesting that the delay information be returned.

The controller 30 transmits the generated request to the Internet 14 through the communication module 23 (S32). Then, the controller 30 waits until the response to the transmitted request is received (S33: No). When the controller 30 determines that the elapsed time from transmitting the request has reached a predetermined time before receiving the response, the controller 30 retransmits the request. The process of step S32 of transmitting a request including a command requesting that the position information be returned is an example of the "position information request process" of the present invention. The process of step S32 of transmitting a request including a command requesting that the delay information be returned is an example of the "delay information request process" of the present invention.

On the other hand, although not shown in the flowchart, the request transmitted by the controller 30 is received by the traffic information server 11. The traffic information server 11 executes a command included in the received request. Specifically, the traffic information server 11 obtains the position information and delay information of the bus 15 traveling on the route including the stop indicated by the installation position information from the traffic database in the transportation (bus) indicated by the type information included in the command. Read and generate a response containing the read information. Then, the traffic information server 11 returns the generated response to the communication address included in the received request. The location information and delay information to be read are information that the management server 12 transmits in advance to the traffic information server 11 and is stored in the traffic database of the traffic information server 11.

When the controller 30 determines that the response has been received (S33: Yes), the controller 30 stores the position information and the delay information included in the received response in the memory 32 (S34). The process of step S33: Yes for receiving the response including the position information is an example of the "position information reception process" of the present invention. The process of step S33: Yes for receiving the response including the delay information is an example of the "delay information reception process" of the present invention.

The controller 30 generates display information to be displayed on the display 21 of the display device 20 based on the position information and the delay information stored in the memory 32 in step S34 (S35). The display information generated in step S35 includes information indicating that the bus 15 is delayed or the delay time of the bus 15 and information indicating the position of the bus 15. The information indicating the position of the bus 15 is, for example, information indicating the address indicating the current position of the bus 15 and the position of the marker displayed on the map. The bus 15 whose position is indicated may be all the buses 15 on the route including the stop where the signage 13 is installed, or between the stop where the signage 13 is installed and the stop next to the stop. It may be the bus 15 located at. The controller 30 selects 15 position information of a predetermined bus from the position information stored in the memory 32 in step S34, and generates display information based on the selected position information. The process of step S34 for generating display information is an example of the "generation process" of the present invention.

The controller 30 inputs the display information generated in step S34 to the display device 20, and displays the route map, the timetable, the position information of the bus 15, and the delay information of the bus 15 on the display 21 (S36). The route map is displayed in the route map display area 41 shown in FIG. The timetable is displayed in the timetable display area 42. The position information and the delay information are displayed in the operation information display area 44. The process of step S36 for displaying the position information and the delay information of the bus 15 on the display 21 is an example of the "display process" of the present invention.

Next, the controller 30 determines whether or not the display end time has come (S37). Specifically, the controller 30 determines whether or not the time indicated by the date and time information input from the clock module 25 is the time when the last bus 15 stored in the memory 32 ends running. When the controller 30 determines that the display end time has not been reached (S37: No), the controller 30 re-executes the processes after step S31. The transmission of the request of step S32, which is repeatedly executed, is executed by polling, for example. That is, the controller 30 repeatedly transmits the request at predetermined time intervals. On the other hand, when the controller 30 determines that the display end time has come (S37: Yes), the controller 30 ends the first display control process.

Next, a second display control process in which the controller 30 displays accident information, disaster information, and emergency information on the display 21 of the display device 20 will be described.

The controller 30 generates a request as shown in FIG. 6 (S41). The generated request includes a first URL, a communication address, type information, installation position information, and a predetermined request. That is, the controller 30 generates a request to be transmitted to the traffic information server 11. The predetermined request is a request for returning event information. That is, the controller 30 generates a request including a command requesting that the event information be returned. The command is stored in the memory 32 in advance.

The command requesting that the event information be returned includes the type information and the installation position information as incidental information. That is, the command is a command for requesting a reply of event information related to the stop indicated by the installation position information for the transportation system (bus) indicated by the type information.

The controller 30 transmits the generated request to the Internet 14 through the communication module 23 (S42). The process of step S42 for transmitting the request generated in step S41 to the traffic information server 11 is an example of the "query process" of the present invention.

On the other hand, although not shown in the flowchart, the request transmitted by the controller 30 is received by the traffic information server 11. The traffic information server 11 executes a command included in the received request. Specifically, the traffic information server 11 confirms the presence / absence of event information regarding the stop indicated by the installation position information in the transportation system (bus) indicated by the type information included in the command. Then, the traffic information server 11 generates a response including the event information when there is event information, and generates a response including information indicating that there is no event information when there is no event information. The traffic information server 11 returns the generated response to the communication address included in the received request.

The event information has a plurality of types. One type of event information indicates an accident. The accident is, for example, an accident related to the bus 15, an accident related to another vehicle on the route of the bus 15, or an accident related to other transportation means such as a train or an aircraft connected to the bus 15.

Another type of event information indicates a disaster. Disasters include, for example, earthquakes, fires, guerrilla thunderstorms, tsunamis, and typhoons on the bus 15 route.

Yet another type of event information indicates an emergency. Emergency situations include, for example, large earthquakes that destroy roads and the occurrence of terrorism.

The controller 30 may send the request generated in step S41 to a server other than the traffic information server 11. For example, when the traffic information server 11 does not distribute information about a disaster or an emergency, the controller 30 transmits the generated request to the server that distributes the information about the disaster or the emergency. Specifically, the controller 30 includes, instead of the first URL, a URL published by the server that distributes information on disasters and emergencies in the request. The URL is stored in advance in, for example, the memory 32.

The controller 30 waits until it receives a response to the transmitted request (S43: No). When the controller 30 determines that the response has been received (S43: Yes), the controller 30 determines whether or not the received response includes event information (S44). When the controller 30 determines that the received response does not include the event information (S44: No), the controller 30 skips the processes from steps S45 to S58. On the other hand, when the controller 30 determines that the received response includes the event information (S44: Yes), the controller 30 determines the type of the event information (S45). The process of step S43: Yes for receiving the response returned by the traffic information server 11 is an example of the "event information reception process" of the present invention.

When the controller 30 determines that the type of event information indicates an accident (S45: accident), the controller 30 generates a request and transmits the generated request to the Internet 14 through the communication module 23 (S46). The request includes a first URL, a communication address, and a command requesting that accident information be returned. The command includes type information and installation position information as incidental information. That is, the controller 30 sends a request to the traffic information server 11 requesting that the transportation (bus) indicated by the type information return the accident information regarding the stop indicated by the installation position information. Accident information includes delay information indicating the type of accident, the location where the accident occurred, the delay time and delay status of the vehicle 15 caused by the accident, detour information indicating the detour route when the accident occurred, and the vehicle. 15 and flight cancellation information indicating cancellations and cancellations of trains and aircraft, and live information changed due to accidents and the like. The process of step S46 for transmitting the request generated in step S45 to the traffic information server 11 is an example of the "accident information request process" of the present invention.

The traffic information server 11 collects accident information from the management server 12, a management server operated by a business operator operating various transportation systems, and the like, and returns the collected accident information in response to a request (request). Response).

The controller 30 waits until it receives the response to the request transmitted in step S46 (S47: No). When the controller 30 determines that the response to the request transmitted in step S46 has been received (S47: Yes), the controller 30 generates display information based on the accident information included in the received response (S48). Then, the controller 30 inputs the generated display information to the display device 20 and displays the accident information on the display 21 (S49). The accident information is displayed in, for example, the operation information display area 44 (FIG. 3). The accident information may be displayed in a dedicated display area provided on the display 21.

The process of step S47: Yes for receiving the response including the accident information is an example of the "accident information receiving process" of the present invention. The process of step S48 for generating display information indicating accident information is an example of the "generation process" of the present invention. The process of step S49 for displaying the accident information on the display 21 is an example of the “display process” of the present invention.

When the controller 30 determines in step S45 that the type of event information indicates a disaster (S45: disaster), the controller 30 generates a request and transmits the generated request to the Internet 14 through the communication module 23 (S50). The request includes a first URL, a communication address, and a command requesting that disaster information be returned. The command includes the above-mentioned type information and installation position information. That is, the controller 30 sends a request to the traffic information server 11 requesting that the transportation (bus) indicated by the type information return the disaster information regarding the stop indicated by the installation position information. The process of step S50 for transmitting a request including a request for returning disaster information is an example of the "disaster information request process" of the present invention.

The controller 30 waits until it receives a response to the request transmitted in step S50 (S51: No). When the controller 30 determines that the response to the request transmitted in step S50 has been received (S51: Yes), the controller 30 generates display information based on the disaster information included in the received response (S52). Then, the controller 30 inputs the generated display information to the display device 20 and displays the disaster information on the display 21 (S53). The disaster information is displayed in, for example, the operation information display area 44. The disaster information may be displayed in a dedicated display area provided on the display 21.

The process of step S51: Yes for receiving a response including disaster information is an example of the "disaster information reception process" of the present invention. The process of step S52 for generating display information indicating disaster information is an example of the "generation process" of the present invention. The process of step S53 for displaying disaster information on the display 21 is an example of the “display process” of the present invention.

When the controller 30 determines in step S45 that the type of event information indicates an emergency (emergency) (S45: emergency), the controller 30 generates a request and transmits the generated request to the Internet 14 through the communication module 23. (S54). The request includes a first URL, a communication address, and a command requesting that emergency information be returned. The command includes the above-mentioned type information and installation position information as incidental information. That is, the controller 30 sends a request to the traffic information server 11 requesting that the transportation (bus) indicated by the type information return emergency information regarding the stop indicated by the installation position information. The process of step S54 for transmitting a request including a request for returning emergency information is an example of the "emergency information request process" of the present invention.

The controller 30 waits until it receives the response to the request transmitted in step S54 (S55: No). When the controller 30 determines that the response to the request transmitted in step S54 has been received (S55: Yes), the controller 30 generates display information based on the emergency information included in the received response (S56). Then, the controller 30 stops the first display control process (FIG. 5), inputs the display information generated in step S56 to the display device 20, and displays the emergency information on the display 21 (S57). The emergency information is displayed on the entire surface of the display 21, for example.

The process of step S55: Yes for receiving a response including emergency information is an example of the "emergency information reception process" of the present invention. The process of step S56 for generating display information indicating emergency information is an example of the "emergency information generation process" of the present invention. The process of step S57 for displaying emergency information on the display 21 is an example of the "emergency information display process" of the present invention.

The controller 30 determines whether or not to end the display of the emergency information (S58). The controller 30 determines that, for example, the display of the emergency information is terminated in response to the release instruction being input by the input device 27. When the controller 30 determines that the display of the emergency information is not finished (S58: No), the controller 30 re-executes the processes after step S54. The controller 30 periodically transmits the request generated in step S54 to the traffic information server 11 at predetermined time intervals, for example, by polling. That is, in an emergency, the signage 13 can always display the latest emergency information.

After executing the processes of steps S49 and S53, the controller 30 determines that the display of the emergency information is finished (S58: Yes), or determines that the event information is not included in the response (S44: No). It is determined whether or not to end the display (S59). The controller 30 determines that the display is terminated in response to the input of the reset instruction using, for example, the input device 27 (S59: Yes). That is, the controller 30 periodically acquires event information day and night and displays accident information, disaster information, and emergency information unless the processing is intentionally completed. The controller 30 periodically and repeatedly transmits the request generated in step S41 by polling or the like (S42).

Next, the third display control process in which the signage 13 displays the PR moving image will be described with reference to FIG. 7. First, the controller 30 accepts the input of the third URL published by the operator server 18 (FIG. 1) (S61). The third URL is input to the signage 13 using, for example, an input device 27 or a portable storage medium. Alternatively, the controller 30 sends a request including a command requesting that the third URL be returned to the management server 12 and acquires the third URL included in the response. The third URL may be the same URL as the second URL. That is, the bus operator or the like may receive the PR video from the contracted operator and distribute it to the signage 13. The third URL is updated when the operator contracting with the bus operator or the like changes.

The controller 30 generates a request in response to the acquisition of the third URL (S62). The request includes a third URL, a communication address, and a command requesting that the PR video be returned. The controller 30 transmits the generated request to the Internet 14 through the communication module 23 (S63). The process of step S53 for transmitting a request including a command requesting that the PR moving image be returned is an example of the "advertising information request process" of the present invention. The PR moving image is an example of the "advertising information" of the present invention.

On the other hand, although not shown in the flowchart, the request transmitted by the controller 30 is received by the operator server 18. The operator server 18 executes the command included in the received request. Specifically, the business server 18 returns to the communication address included in the request for receiving the response including the PR moving image stored in the attached memory.

The controller 30 waits until it receives the response to the request transmitted in step S63 (S64: No). When the controller 30 determines that the response has been received (S64: Yes), the controller 30 stores the PR moving image included in the received response in the memory 32 (S65). The process of step S64: Yes for receiving the response including the PR moving image is an example of the "advertisement information receiving process" of the present invention. The process of step S65 for storing the PR moving image in the memory 32 is an example of the “storage process” of the present invention.

The controller 30 generates display information based on the PR moving image stored in the memory 32 (S66), inputs the generated display information to the display device 20 to display the PR moving image on the display 21 (S67), and the third End the display control process. The PR moving image is displayed in the PR display area 43 (FIG. 3). Instead of the PR moving image, a still image may be displayed in the PR display area 43. That is, the business server 18 returns a response including a still image instead of the PR moving image. The still image is an example of the "advertising information" of the present invention. The process of step S66 for generating display information is an example of the "generation process" of the present invention. The process of step S67 for displaying the PR image on the display 21 is an example of the "display process" of the present invention.

The function of displaying the PR moving image in the signage 13 is a matter that can be appropriately selected. That is, the signage 13 may or may not have a function of displaying a PR moving image.

The controller 30 displays information on the display 21 according to the presence or absence of a person detected by the motion sensor 24 during the execution of the first display control process, the second display control process, and the third display control process. Execute or stop input. That is, when there is no person around the signage 13, the controller 30 stops the display on the display 21 to suppress wasteful consumption of electric power. The process in which the controller 30 determines the presence or absence of a person according to the detection signal output by the motion sensor 24 is an example of the "determination process" of the present invention. A camera may be used instead of the motion sensor 24. Gamera images the surroundings of the signage 13 to generate image data, and transmits the generated image data to the controller 30, which determines the presence or absence of a person based on the input image data.

Further, the controller 30 causes the display 21 to display a switching icon for switching the display of the route map, the timetable, and the operation management information. Then, the controller 30 monitors whether or not the user touches the switching icon. Specifically, the controller 30 monitors the detection signal output by the touch sensor.

When the controller 30 determines that the user has touched the switching icon, the controller 30 switches the screen to be displayed on the display 21. Specifically, the controller 30 switches the display from the display of one of the plurality of route maps to the display of another route map. Alternatively, the controller 30 switches the display from the display of the timetable of one line to the display of the timetable of another line. Alternatively, the controller 30 switches the display from the display of the operation information of one line to the display of the operation information of another line. The detection signal output by the touch sensor 22 in response to a human touch is an example of the "display switching instruction" of the present invention. The process in which the controller 30 accepts the input of the detection signal output by the touch sensor 22 in response to a human touch is an example of the "display switching acceptance process" of the present invention. The process of switching the display content to be displayed on the display 21 by the controller 30 is an example of the "display switching process" of the present invention.

Whether or not the motion sensor 24 and the touch sensor 22 are mounted is a matter that can be appropriately selected. That is, the signage 13 may not have a function of switching between display and non-display on the display 21 depending on the presence or absence of people around, or may not have a function of switching and displaying the screen.

Next, the localization of the signage 13 will be described. When the controller 30 determines that the bus 15 will arrive at the installed stop soon based on the position information of the bus 15 stored in the memory 32 in step S34, for example, "the bus 15 will arrive soon" or the like. Display. The memory 32 stores standard display information such as "bus 15 will arrive soon" in a plurality of languages in association with each language ID. The language ID is an example of the "designated language information" of the present invention.

The controller 30 accepts the input of the language ID. The language ID is input to the signage 13 using, for example, the input device 27. The controller 30 reads the standard display information corresponding to the input language ID from the memory 32, and displays the read standard display information on the display 21. The process in which the controller 30 acquires the language ID is an example of the "designated language acquisition process" of the present invention. The process of displaying the standard display information on the display 21 by the controller 30 is an example of the "display process" of the present invention.

Further, the controller 30 receives an input of a detection value corresponding to at least one value of the DC current, the DC voltage, and the DC power supplied to the display 21. For example, a detection circuit for detecting the direct current supplied to the display 21 is provided, and the output end of the detection circuit is connected to the communication bus 38. The detected value corresponding to at least one value of the DC current, the DC voltage, and the DC power supplied to the display 21 is an example of the "operation information" of the present invention. The process in which the controller 30 accepts the input of the detected value is an example of the "acceptance process" of the present invention.

The controller 30 determines whether or not the received detection value is within the threshold range stored in the memory 32. The process in which the controller 30 makes the determination is an example of the "self-diagnosis process" of the present invention. When the controller 30 determines that the received detection value is not within the threshold range stored in the memory 32, the controller 30 transmits failure information indicating that the display 21 has a failure to the e-mail address stored in the memory 32. do. The e-mail address is, for example, the e-mail address of a person in charge of a bus company or the like. The e-mail address is input to the signage 13 using the input device 27 before the signage 13 is installed at the bus stop or after the signage 13 is installed at the bus stop. The controller 30 stores the input e-mail address in the memory 32. The process in which the controller 30 transmits an e-mail containing failure information is an example of "failure information processing" of the present invention.

Next, FIG. 8 describes the timetable revision process executed by the controller 30 when the signage 13 displays the route map and timetable after the timetable revision on the display 21 when the timetable such as the route and the timetable is revised. Will be explained with reference to.

First, the controller 30 generates a request (S71). The request includes a first URL, a communication address, and a command requesting that event information indicating the presence or absence of an event including timetable revision be returned. The command includes type information and installation position information as incidental information. That is, the controller 30 generates a request for inquiring to the traffic information server 11 whether or not there is an event such as a timetable revision for the route including the bus stop indicated by the installation position information, which is the transportation system (bus) indicated by the type information. .. The controller 30 transmits the generated request to the Internet 14 through the communication module 23 (S72). The process of step PS72 for transmitting a request for inquiring whether or not there is a timetable revision is an example of the "inquiry process" of the present invention.

On the other hand, although not shown in the flowchart, the request transmitted by the signage 13 is received by the traffic information server 11. The traffic information server 11 executes a command included in the received request. Specifically, the traffic information server 11 confirms whether or not the information regarding the timetable revision and the like is stored in the traffic database. When the controller 30 determines that the information regarding the timetable revision or the like is not stored in the traffic database, the controller 30 generates a response including event information indicating that there is no timetable revision, and returns the response to the communication address included in the received request. When the traffic information server 11 determines that the information related to the timetable revision is stored in the traffic database, it generates a response including event information indicating that there is a timetable revision, and returns it to the communication address included in the received request. ..

The controller 30 waits until it receives the response to the request transmitted in step S72 (S73: No). When the controller 30 determines that the response has been received (S73: Yes), the controller 30 determines whether or not there is a timetable revision based on the event information included in the response (S74). When the controller 30 determines that there is no timetable revision (S74: No), the controller 30 ends the timetable revision process. The process of step S73: Yes for receiving the response returned by the traffic information server 11 is an example of the "event information reception process" of the present invention.

When the controller 30 determines that there is a timetable revision (S74: Yes), the controller 30 generates a request (S75). The request includes a first URL, a communication address, a command requesting that the date and time of the timetable revision, route information after the timetable revision, and departure time information after the timetable revision be returned. The command includes type information and installation position information as incidental information. That is, the controller 30 returns the date and time of the timetable revision, the route information after the timetable revision, and the departure time information for the route including the bus stop indicated by the installation position information, which is the transportation system (bus) indicated by the type information. Generates a request to be requested from the traffic information server 11. The controller 30 may generate a plurality of requests in step S75. One request includes a command requesting that the date and time of the timetable revision be returned. The other request includes a command requesting that the route information after the timetable revision be returned. Yet another request includes a command requesting that the departure time information after the timetable revision be returned.

The controller 30 transmits the request generated in step S75 to the Internet 14 through the communication module 23 (S76).

On the other hand, although not shown in the flowchart, the request transmitted by the signage 13 is received by the traffic information server 11. The traffic information server 11 executes a command included in the received request. Specifically, the controller 30 reads out the date and time of the timetable revision, the route information after the timetable revision, and the departure time information after the timetable revision from the data table. The traffic information server 11 returns a response including the read date / time of the timetable revision, the route information after the timetable revision, and the departure time information after the timetable revision to the communication address included in the received request.

The controller 30 of the signage 13 waits until the response to the request transmitted in step S76 is received (S77: No). When the controller 30 determines that the response has been received (S77: Yes), the controller 30 stores the date and time of the timetable revision included in the response, the route information after the timetable revision, and the departure time information after the timetable revision in the memory 32 (S78). ..

The controller 30 waits until the date indicated by the date and time information output by the clock module 25 becomes the date indicated by the timetable revision date and time stored in the memory 32 (S79: No). When the controller 30 determines that the date indicated by the date and time information output by the clock module 25 is the date indicated by the timetable revision date and time stored in the memory 32 (S79: Yes), the route information and departure time information after the timetable revision Is read from the memory 32. The controller 30 generates display information based on the read route information and departure time information after the timetable revision (S80). The controller 30 inputs the generated display information to the display device 20, displays the route information and the departure time information after the timetable revision on the display 21 (S81), and ends the timetable revision process. The controller 30 executes the timetable revision process at a predetermined time every day (for example, midnight).

Although not shown in the flowchart, the controller 30 displays the route information and the departure time information after the timetable revision on the display 21 in step S81, and then the route information, the departure time information, and the departure time information before the timetable revision. Delete the timetable revision date and time from the memory 32.
