2. Description of the Related Art Conventionally, systems for providing traffic information to vehicle occupants have been in operation. One of the representative systems is ITS (Intelligent Transport Systems). In ITS, a center that analyzes information collected from the outside generates road traffic information and transmits it to vehicles. Then, the vehicle receives the road traffic information transmitted by the center, and notifies the passenger of the content of the received road traffic information through the car navigation device of the vehicle by display or voice.

By the way, in ITS, a center collects information from sensors on the road.

Then, the in-vehicle unit 10 automatically records the acquired operation information.

Further, when a special event occurs, the vehicle-mounted unit 10 temporarily executes the recording function of the drive recorder based on a trigger signal generated inside the vehicle-mounted unit 10 . A case where a special event occurs is, for example, a case where occurrence of a large acceleration is detected, that is, a case where the host vehicle collides, abrupt braking, or the like occurs.

A specific configuration example of the in-vehicle unit 10 will be described below with reference to FIG. FIG. 2 is a block diagram showing a schematic configuration example of the in-vehicle unit 10. As shown in FIG.

As shown in FIG. 2, the vehicle-mounted unit 10 of this embodiment has a microcomputer (CPU) 11 . It also has speed, engine, GPS, analog, external input, H/T input, SWU input, camera, communication, and memory card interfaces (I/F) 12-19, 21, 25. FIG. Further, the vehicle-mounted unit 10 of this embodiment has a nonvolatile memory 22 , a volatile memory 23 , a switch (SW) input section 26 and a liquid crystal display (LCD) 27 .

The CPU 11 (corresponding to an information collection unit, a confirmation request reception unit, a correctness confirmation unit, a result transmission unit, and an information transmission unit in the claims) executes a pre-installed program to obtain information necessary for the in-vehicle unit 10. It performs processing to realize various functions. This function includes a digital tachograph data recording function, a drive recorder function, a function of notifying the sequencer 30 of an alarm, and the like.

A speed I/F 12 converts a speed pulse signal output from the track 1 side into a signal suitable for processing by the CPU 11 . By monitoring this speed pulse signal, the CPU 11 can grasp the running speed and the moving distance of the own vehicle. The engine I/F 13 converts an engine pulse signal output from the truck 1 side into a signal suitable for processing by the CPU 11 . The CPU 11 can grasp the rotation speed of the engine by monitoring this engine pulse signal.

The GPSI/F 14 performs signal processing on the output signal of the GPS receiver (not shown) on the track 1 so that it can be input to the CPU 11 . The GPS receiver can receive radio waves from a plurality of GPS (Global Positioning System) satellites and calculate the current position of the truck 1 based on the time of the received signals.

The analog I/F 15 incorporates a converter that converts a predetermined analog signal into a digital signal readable by the CPU 11 . The external input I/F 16 performs signal processing for inputting to the CPU 11 an output signal from a predetermined external device (not shown).

The H/T input I/F 17 performs signal processing for inputting the output signal of a handy terminal (H/T) (not shown) to the CPU 11 . The H/T is a terminal equipped with, for example, a numeric keypad for inputting numerical values, a card reader for reading magnetic or IC card data, and the like.

The SWU input I/F 18 performs signal processing for inputting to the CPU 11 with respect to an output signal of a switch unit (SWU) (not shown). The SWU is a unit connected to the in-vehicle unit 10 as optional equipment. The SWU can be provided with, for example, a switch or the like operated by the crew of the truck 1 in order to input the type of event that occurred during operation of the truck 1 . The in-vehicle unit 10 already has a SW input section 26 as a switch for inputting the type of event. Therefore, the switches of the SWU can be used to input events of a type that cannot be input by the switches of the SW input section 26 .

Camera I/F 19 is connected to camera 20 (one or more). The camera 20 is arranged so as to photograph the road in front of the truck 1 in the direction of travel, other vehicles, scenery outside the vehicle, etc., photograph the interior of the truck 1, and record sounds inside and outside the truck 1. be. The camera I/F 19 performs processing for converting analog image signals and audio signals output by the camera 20 into digital signals that can be input to the CPU 11 .

The communication I/F 21 performs signal processing on input/output signals of the CPU 11 for communication with the sequencer 30 via the wireless LAN of the track 1 .

The nonvolatile memory 22 is composed of a flash memory or the like, and can be accessed by the CPU 11 to read and update data as necessary. Each storage area on the nonvolatile memory 22 can be used to store programs, constant data, tables, etc. that are referred to by the CPU 11 .

The volatile memory 23 is composed of a semiconductor memory (such as RAM) from which data can be freely read and written by access from the CPU 11, and is used to temporarily hold various data generated by the CPU 11 and the like.

The memory card I/F 25 can detachably hold a memory card 24 using a flash memory or the like. The CPU 11 can access the mounted memory card 24 via the memory card I/F 25 to read and write data.

A separate memory card 24 can be used for each crew member of the truck 1, for example. In this case, a unique crew member code, for example, can be written in the memory card 24 in advance as management information. Each crew member mounts his/her own memory card 24 to the vehicle-mounted unit 10, for example, when getting on the truck 1 and starting operation.

By attaching the memory card 24 to the in-vehicle unit 10, the CPU 11 can be made to recognize the occurrence of the truck 1 leaving event. Similarly, by taking out the memory card 24 attached to the in-vehicle unit 10, the CPU 11 can be made to recognize the occurrence of the warehousing event of the truck 1. FIG. Of course, it is also possible to cause the CPU 11 to recognize the occurrence of an event of delivery or receipt by other methods.

Under the control of the CPU 11, the LCD 27 can display character information such as the date and time, the operating state of the vehicle unit 10, messages, etc. in such a manner that the crew can easily view them.

Then, the CPU 11 stores the collected operation information in the memory card 24 via the memory card I/F 25 .

In addition, the CPU 11 of the in-vehicle unit 10 analyzes the contents of the collected operation information or changes in time series to detect the occurrence of an alarm state. Then, when detecting the occurrence of an alarm state, the CPU 11 outputs an alarm signal indicating the type of the detected alarm state from the communication I/F 21 to the sequencer 30 . The alarm state detected by the CPU 11 can be, for example, sudden start or sudden braking of the truck 1, revving of the engine, or the like.

Furthermore, the CPU 11 of the in-vehicle unit 10 analyzes the image signal input from the camera 20 via the camera I/F 19 and detects the establishment of the specific condition. Then, when CPU 11 detects that the specific condition is established, CPU 11 outputs a detection signal indicating the type of the detected specific condition from communication I/F 21 to sequencer 30 . For example, if the captured image of the camera 20 includes patrol lights (registered trademark, the same shall apply hereinafter) of a patrol car or another vehicle with flashing hazard lamps, the CPU 11 detects the patrol light image or the flashing of the hazard lamps. A signal is output to the sequencer 30 .

Note that the communication I/F 21 of the present embodiment outputs an alarm signal or a detection signal to the sequencer 30 using three-channel voltage signals by open collector output.

Returning to FIG. 1 , the sequencer 30 is a dedicated controller that controls the operation of the vehicle-mounted unit 10 . The sequencer 30 can be configured by a computer such as a PLC (Programmable Logic Controller) that operates according to a rewritable program, for example.

The sequencer 30 is wire-connected to the vehicle-mounted unit 10 by a signal cable. Also, the sequencer 30 can be connected to a wireless LAN in the truck 1 via a built-in wireless LAN (Local Area Network) interface (not shown).

Also, the sequencer 30 transmits an alarm signal or a detection signal input from the in-vehicle unit 10 to the cloud 2 via a Wi-Fi router 50, which will be described later.

The commu-robo 40 incorporates a smart speaker (not shown) having a processor. The smart speaker can connect to the wireless LAN inside the truck 1 via a built-in wireless LAN interface (not shown).

The smart speaker can capture the speech content of the crew member 70 of the truck 1 with the built-in microphone and transmit it to the robot server 80 of the cloud 2 (described later) via the Wi-Fi router 50 . In addition, the smart speaker can reproduce and output an audio file input from the robot server 80 via the Wi-Fi router 50 using the built-in speaker.

In addition, smart speakers have built-in output devices for visual recognition. In this embodiment, as an output device for visual recognition, the commu-robo 40 has a light-emitting device 41 arranged in the eye portion. The light emitting device 41 can be turned on under the control of the processor when an activation signal for the communication robot 40 is input from the robot server 80 to the smart speaker via the Wi-Fi router 50 .

The Wi-Fi router 50 interconnects the wireless LAN in the track 1 and the wireless WAN (Wide Area Network) on the Internet side.

A unique global IP address is assigned to the Wi-Fi router 50 . This global IP address is used for communication between the Wi-Fi router 50 and the server of the cloud 2 or the like.

The Wi-Fi router 50 is assigned an SSID (Service Set Identifier) as an access point identification name (network name). The same SSID as the Wi-Fi router 50 is set to the sequencer 30 and the commu-robo 40 to enable communication with the Wi-Fi router 50 on the wireless LAN of the truck 1 .

The DC/AD converter 60 converts the DC power of a 24V lead battery (not shown) mounted on the truck 1 into 100V AC power and supplies it to the Wi-Fi router 50 .

The cloud 2 is composed of multiple servers on the Internet. The cloud 2 has a robot server 80 , a data reception/utterance instruction server 90 , a voice analysis physical condition determination server 100 and a weather forecast application (APL) server 110 .

The robot server 80 communicates with the commu-robo 40 on the truck 1 via the Wi-Fi router 50 . Further, the robot server 80 communicates with each of the servers 90 to 110 for data reception/speech instruction, voice analysis physical condition determination, and weather forecast APL on the Internet.

The robot server 80 executes the speech recognition program and the speech synthesis program, thereby performing mutual conversion between the speech signal of the speech file and the text data.

The data reception/utterance instruction server 90 communicates with the sequencer 30 of track 1 via the Wi-Fi router 50 . The data reception/utterance instruction server 90 also communicates with the robot, voice analysis physical condition determination, and weather forecast APL servers 80, 100, and 110, respectively, on the Internet. The data reception/utterance instruction server 90 can constitute a vehicle information distribution device, a distribution request reception section, a confirmation request transmission section, a result reception section, an information distribution section, an information reception section, and an information generation section.

For example, the data reception/utterance instruction server 90 can receive, via the Wi-Fi router 50, an alarm signal or detection signal output by the in-vehicle unit 10 to the sequencer 30. FIG. Upon receiving the alarm signal or detection signal, the data reception/speech instruction server 90 searches for an audio file corresponding to the content of the alarm signal or detection signal. Then, the searched voice file is output through the robot server 80 to the commu-robo 40 of the track 1 to which the sequencer 30 has output the alarm signal or detection signal.

The audio file output by the data reception/utterance instruction server 90 informs the crew member 70 of the truck 1 that an alarm has occurred or a specific condition has been established, and the type of the alarm condition that has occurred or the specific condition that has been established. This is a file of an audio signal that notifies by voice. This voice file can be saved as a search candidate in a database of a storage device such as a hard disk or SSD (Solid State Drive) of the data reception/utterance instruction server 90, for example.

Further, the data reception/utterance instruction server 90 receives from the robot server 80 the audio file of the contents of the utterance of the crew member 70 which the robot server 80 received from the communication robot 40 . Then, the data reception/utterance instruction server 90 converts the received voice file into text data and analyzes the contents of the utterance of the crew member 70 . Furthermore, the data reception utterance instruction server 90 performs processing according to the contents of the analyzed utterance of the crew member 70 .

For example, when the content of the utterance by the crew member 70 is a word such as “Hey, Commu-Robo” to prompt the activation of the Commu-Robo 40 , the data reception/utterance instruction server 90 outputs an activation signal to the Commu-Robo 40 via the robot server 80 . When words such as "Tell me" prompting the activation of the commu-robo 40 of the truck 1 on which another crew member 70 is on duty continue, the data reception utterance instruction server 90 sends the activation signal of the commu-robo 40 to the robot server 80. to the commu-robo 40 of each track 1 via the

Further, when the content of the utterance of the crew 70 after the commu-robo 40 is activated is, for example, a message to the crew 70 of each truck 1, the data reception utterance instruction server 90 sends the received voice file to the robot server 80. to the commu-robo 40 of each track 1 via the

Furthermore, if the content of the utterance by the crew member 70 after the activation of the communication robot 40 is, for example, an inquiry, the data reception/utterance instruction server 90 generates a command according to the content of the inquiry. Then, data reception/utterance instruction server 90 transmits the generated command to weather forecast APL server 110 or smart phone 120 that provides an answer to the content of the inquiry over the Internet.

Further, when the contents of the utterance of the driver 70 after the commu-robo 40 is activated are, for example, the contents of notifying the road conditions at the traveling point of the truck 1 on duty, the data reception/utterance instruction server 90 obtains by analysis Generate a command requesting confirmation of the occurrence of road conditions. Then, the data reception/utterance instruction server 90 transmits the generated command via the robot server 80 to the commu-robo 40 of the truck 1 on which the crew member 70 who made the utterance is on board.

Furthermore, when the data reception/utterance instruction server 90 receives a command confirming the occurrence of road conditions via the robot server 80, the received road condition voice file is sent to the commu-robot of each truck 1 via the robot server 80. 40.

In order to determine the physical condition of the crew member 70, the data reception/utterance instruction server 90 transmits the contents of the speech of the crew member 70 to the voice analysis physical condition determination server 100 at any time over the Internet.

The voice analysis physical condition determination server 100 analyzes the uttered voice of the crew member 70 received from the data reception/utterance instruction server 90 and determines whether the crew member 70 is in good or bad physical condition. Then, a signal indicating the determination result is transmitted via the data reception/speech instruction server 90 to the sequencer 30 of the truck 1 on which the crew member 70 who spoke is on board.

If the result of this determination is poor physical condition, the sequencer 30 provides the in-vehicle unit 10 with a threshold (alarm threshold) used by the CPU 11 to detect from the collected operation information that the truck 1 is in an alarm state. Outputs a command signal that changes the With this command signal, the sequencer 30 commands the CPU 11 of the vehicle-mounted unit 10 to change the alarm threshold to a value that makes it easier to determine that the truck 1 is in the alarm state than usual.

When the weather forecast APL server 110 receives a weather forecast inquiry command from the data reception/utterance instruction server 90 , it transmits weather forecast data such as the area and date of the inquiry to the robot server 80 . Upon receiving the weather forecast data from the weather forecast APL server 110, the robot server 80 generates an audio file by converting the received weather forecast data into audio data. Then, the robot server 80 transmits the generated voice file to the commu-robo 40 of the truck 1 on which the crew member 70 who inquired about the weather forecast is on board.

The office (home) 3 is an office where the crew member 70 of the truck 1 works or a facility corresponding to the home of the crew member 70 . The smartphone 120 in the office (home) 3 is owned by a person or a family member of the crew member 70 who is in the office (home) 3 .

The smartphone 120 can be used to create an audio file of a voice message to the crew member 70 output from the commu-robo 40 using the voice of a person at work or a family member. This voice file is transmitted from the data reception/utterance instruction server 90 to the communication robot 40 via the robot server 80 . A voice file created by the smartphone 120 can be transmitted to the data reception/utterance instruction server 90 by operating a web console screen (not shown) displayed on the display of the smartphone 120, for example.

Further, when the smartphone 120 receives a calendar information inquiry command from the data reception/utterance instruction server 90 , the smartphone 120 transmits data of the calendar information for which the inquiry was received to the robot server 80 . The robot server 80 that has received the received calendar information data generates an audio file by converting the received calendar information data into audio data. Then, the robot server 80 transmits the generated voice file to the commu-robo 40 of the truck 1 on which the crew member 70 who inquired about the calendar information is on board.
