Description

TECHNICAL FIELD The present invention relates to a communication system for specially equipped vehicles, and more particularly to improving communication quality within a cabin.

Specially equipped vehicles are used in which accessories such as garbage collectors are attached to the vehicle. In addition, a control device is provided for controlling and driving the mountings and the like. In this control device, the movable state of the equipment is recorded as data.

In order to manage the operating status, this operating status data is transmitted to the server device. For example, Patent Literature 1 discloses a system as shown in FIG.

A cabin 302 for the driver to drive is provided in front of the specially equipped vehicle. A control device 304 is provided on the vehicle body of the specially equipped vehicle. A short-range wireless communication device 306 is connected to the control device 304 .

In cabin 302 , an in-cabin control device (not shown) having buttons for giving control commands to control device 304 is provided. A control signal from the in-cabin control device is provided to the control device 304 via wiring. In response to this, the control device 304 controls each unit and records the operating status data.

A user terminal device (not shown) such as a smartphone operated by an operator communicates with the control device 304 via the short-range wireless communication device 306 . Then, the operating status data recorded in the control device 304 is acquired. The user terminal device transmits the acquired operational status data to the server device on the Internet through wireless communication by the carrier.

JP 2020-127192 A

However, the conventional techniques as described above have the following problems.

First, when an operator uses a user terminal device, it is often done inside the cabin 302 . The cabin 302 has a metal outer shell with glass such as a window embedded therein, and there is a problem that radio waves are shielded by the metal outer shell, making communication impossible or unstable.

This point is likely to be solved if the short-range wireless communication device 306 is provided in the cabin 302, but even in this case, the following second problem cannot be solved.

Secondly, wiring 308 had to be provided separately from the control device 304 for the short-range wireless communication device 306, which was complicated. In specially equipped vehicles, which often have movable devices, there is a demand that such wiring 308 should not be increased as much as possible in order to avoid disconnection due to contact with the movable devices.

The operating motion data storage means 166 stores the acquired operating motion data. The operating motion data transmission means 162 transmits the operating motion data to the management server based on the determined transmission conditions. The connection management means 161 issues an alert when the wireless communication with the connected control device for the specially equipped vehicle is disconnected. The transmission condition setting means 163 sets transmission conditions for the operation data transmission means 166 . This transmission condition includes both an automatic transmission mode in which automatic transmission is performed at predetermined time intervals and an occasional transmission mode when a transmission request is received from the user.

The special-purpose vehicle management server 100 includes user-by-user operation data storage means 107 , operation status report data generation and transmission means 103 , and map data generation and transmission means 105 . The user-by-user operating motion data storage means 107 stores the operating motion data received from the user portable device 160 for each user. The operating status report data generating and transmitting means 103 reads the operating action data for each user from the operating action data storing means 107 for each user, generates the operating status report data for each user, and transmits the data to the user side manager terminal device 120 . . The map data generating and transmitting means 105 stores map data, generates moving track map data in which positions read from each operation data are arranged in chronological order, and transmits the data to the user-side administrator terminal device 120 .

The user-side administrator terminal device 120 includes display control means 121 , display means 123 , and operation status report data request means 125 . The operating status report data requesting means 125 requests the specially equipped vehicle management server 100 for the operating status report data. The display control means 121 receives the operating status report data from the special purpose vehicle management server 100 and displays it on the display means 123 .

As described above, the transmission conditions of the operating operation data transmission means 166 are both an automatic transmission mode in which automatic transmission is performed at predetermined time intervals and an occasional transmission mode when a transmission request is received from the user. As a result, it becomes possible to transmit the operation data of the specially equipped vehicle in a manner other than the periodic transmission.

4. Hardware configuration (4.1 Hardware configuration of special purpose vehicle management server 100)

Such operating data is provided via user-worn device 160 .

In this embodiment, Windows 10 (registered trademark or trademark) is used as the operating system program (OS) 26o, but it is not limited to this.

Each of the above programs is read from the CD-ROM 25a storing the programs via the optical drive 25 and installed in the hard disk 26. FIG. In addition to the CD-ROM, a program such as a flexible disk (FD) or an IC card may be installed from a computer-readable recording medium to a hard disk. Furthermore, it may be downloaded using a communication line.

However, without being limited to this, the program stored in the CD-ROM may be directly executed from the optical drive 25. FIG. In addition, the programs that can be executed by the computer include those that can be directly executed by simply installing them as they are, as well as those that need to be converted into other formats once (for example, decompressing compressed data). ), and also those that can be executed in combination with other module parts.

(4.2 Hardware configuration of user portable device 160)
User-worn device 160 will be described with reference to FIG. This figure shows an example of a hardware configuration in which the user terminal device 120 is configured using a CPU.

The user-worn device 160 has a configuration of a general smart phone, and includes a CPU 123, a memory 127, a flash memory 126, a display unit 130, a wireless communication unit 128, an operation unit 125, an audio input/output unit 124, a position information detection unit 122, a near It has a distance wireless communication unit 121 and a bus line 129 . The position information detection unit 122 is a module that detects position information by GNNS (Global Navigation Satellite System). The short-range wireless communication unit 121 performs communication according to the Bluetooth (registered trademark) standard. In this embodiment, iOS (trademark) is adopted as the OS.

The CPU 123 controls each part via the bus line 129 according to each program stored in the flash memory 126 .

The flash memory 126 has an operating system program 126o (hereinafter abbreviated as OS) and a main program 126m.

The processing of the main program 126m will be described later.

In this embodiment, Bluetooth (registered trademark) is used as the short-range wireless communication unit, but it is not limited to this.

The flash memory 126 has an operation data storage section 126k and a transmission condition storage section 126d. The operating motion data in the operating motion data storage unit 26d is stored in the user terminal device 160 in the following procedure. Based on the main program 126m, the CPU 123 periodically (for example, every 30 seconds) establishes a short-range wireless connection with the control device 201 (see FIG. 3), and issues an operation data acquisition command. Upon receiving such an acquisition command, the control device 201 of the specially equipped vehicle transmits to the user terminal device 160 the operation data stored in the memory (not shown in FIG. 2) in the mounted equipment side control device UK. . When the CPU 123 receives such operating motion data, it stores it in the operating motion data storage unit 126k.

(4.3 Hardware configuration of user-side administrator terminal device 120)
The hardware configuration of the user-side administrator terminal device 120 shown in FIG. 3 is the same as that shown in FIG. 4, and the processing by the main program registered in the hard disk is different as will be described later.

5. Working Motion Data Transmission Processing The working motion data transmission processing from the user portable device 160 to the specially equipped vehicle management server 100 in the specially equipped vehicle running motion data management system 1 will be described with reference to FIG.

In the following, the user (special vehicle operator) with the user ID 1001 enters the ID and password of the user ID 1001 to log in to the special purpose vehicle operation data management system 1, and operates by Bluetooth connection with the control device 201 with the production number 17R810008M. A case of acquiring operation data and transmitting it to the specially equipped vehicle management server 100 will be described.

After logging in to the special purpose vehicle operation data management system 1, when the control device 201 with the production number 17R810008M and the user portable device 160 are connected via Bluetooth, a screen as shown in FIG. 9A is displayed on the screen of the user portable device 160. FIG. Here, the user clicks the transmission setting button 310 . As a result, the transmission condition setting process shown in FIG. 8A is started.

CPU 123 of user-worn device 160 displays the transmission setting screen shown in FIG. 9B (step S1 in FIG. 8A). The user operates the periodic transmission mode frame 331 and the occasional transmission mode frame 333 to input the frequency of the periodic transmission mode and the transmission conditions of the occasional transmission mode, and selects the setting change button 335 (see FIG. 9B).

After displaying the transmission setting screen, the CPU 123 determines whether the cancel button 337 or the setting change button 335 is selected (steps S3 and S5 in FIG. 8A). In this case, since the setting change button has been pressed, the frequency of the periodic transmission mode and the occasional transmission mode are set in the selected transmission conditions (step S7). Such transmission conditions are stored in the transmission condition storage section 126d of the flash memory 126 (see FIG. 7).

Here, it is assumed that the periodical transmission mode is set to every one minute and the occasional transmission mode is set to ON.

The CPU 123 determines whether the occasional transmission mode is ON (step S8), and if it is ON, sets the transmission button 312 (see FIG. 9A) to active.

In the present embodiment, the active display is displayed by enclosing the outer frame in bold so that the user can understand that the button is selectable, but the present invention is not limited to this.

Also, when the cancel button is pressed in step S3, the transmission setting is terminated. If the occasional transmission mode is OFF in step S8, the transmission button is deactivated (step S10).

In addition, the setting is displayed on the display section 314 of the regular transmission frequency and occasional transmission mode in FIG. 9A (not shown).

As already explained, the operation data is repeatedly and automatically obtained at predetermined time intervals from the control device 201 with the manufacturing number 17R810008M connected via Bluetooth. The CPU 123 of the user-worn device 160 stores this in the operation data storage section 126K (see FIG. 7). For example, in the case of a garbage truck, the operation data includes the accumulated number of times (accumulated number of loadings, number of T/G operations, PTO operation time) and various error histories.

Processing for transmitting such operating motion data to the specially equipped vehicle management server 100 will be described with reference to FIG. 8B. In the following description, it is assumed that the user selects the occasional transmission button and transmits data, instead of the transmission timing in the periodical transmission mode.

CPU 123 of user-worn device 160 determines whether or not the periodic transmission mode is ON (step S11). In this case, since the periodic transmission mode is on, the transmission frequency is read and set.

Based on the transmission mode set in this manner, the operation data acquired by the user-worn device 160 is transmitted to the specially equipped vehicle management server 100 . Transmission processing will be described with reference to FIG. 8B.

Below, the operation screen (see FIG. 9A) is displayed on the user portable device 160, and the processing when the user presses the transmission setting button 310 will be described. It is also assumed that the periodic transmission mode frequency is “5 minutes” and the occasional transmission mode is “on”.

The CPU 123 of the user-worn device 160 determines whether or not the periodic transmission mode is ON (step S11). Since the periodical transmission mode is currently on, the transmission frequency is read from the flash memory 126 and set in the timer (step S12). In this case, since the periodic transmission frequency is 5 minutes, the timer is set to "5 minutes". The CPU 123 starts a timer (step S13). The CPU 123 determines whether or not the remaining time on the timer is "0" (step S15).

In this case, the timer remaining is not "0", so the CPU 123 determines whether or not there is a transmission command from the control device 201 (step S17). A transmission command from the control device 201 will be described later.

If there is no transmission command from the control device 201, the CPU 123 determines whether or not the transmission button has been pressed (step S18). In this case, since the send button is pressed at any time, it is determined whether the control device 201 is connected via Bluetooth (step S19). If the control device 201 is connected via Bluetooth, the CPU 123 generates operation data by adding the current time to the operation data (accumulated loading times, accumulated TG lift times, PTO operating time, and position data). The operating motion data is transmitted to the specially equipped vehicle management server 100 (step S23).

If the Bluetooth connection with the control device 201 is not established in step S19, the CPU 123 displays an alert to the effect that the connection is disconnected (step S21).

The occasional transmission command from the control device 201 in step S17 will be described.

In the in-cabin control device UF shown in FIG. 2, the operation switches CR-SW1 to 3 or the operation switches CF-SW1 to 3 are pressed separately from regular exchange of operation data based on commands from the user portable device 160. Then, the operation data at that time (timing) is transmitted to the user-worn device 160 via the short-range wireless unit 63 . This is because these switches indicate that the mounted object K of the specially-equipped vehicle has been operated or that an error has occurred, and it is meaningful to collect the data at that time. The CPU 123 of the user-worn device 160 determines the reception of such data as a transmission command from the control device 201, and executes the process of step S19 in FIG. 8B.

In this embodiment, when the operation switches CR-SW1 to 3 or the operation switches CF-SW1 to 3 are pushed, the vehicle-side control device for the specially equipped vehicle transmits the operating operation data at that time, but it is limited to this. Instead, when the switch is operated, a notification to that effect may be sent to the user-worn device 160 and a command to acquire the operating motion data from the user-worn device 160 may be given to the control device 201 .

If the periodic transmission mode is off (OFF) in step S11, the process proceeds to step S17 to determine the occasional transmission mode.

As described above, the operation data from each user portable device 160 is transmitted to the specially equipped vehicle management server 100 . Upon receiving such data, the CPU 23 of the specially equipped vehicle management server 100 stores the data in the user-by-user operation data storage unit 26 .

Further, when the periodical transmission mode is ON and the timer remaining amount is "0", the processing from step S19 onwards is executed. As a result, operation data (including position data) is periodically transmitted to the specially equipped vehicle management server 100 .

Thus, in this embodiment, the setting of the periodic transmission mode and/or the occasional transmission mode can be switched off. As a result, when communication with the specially-equipped vehicle management server 100 is difficult to establish, flexible communication settings such as disconnecting the regular transmission mode are possible.

In addition, in the occasional transmission mode, occasional transmission is possible when the operator determines that it is necessary, other than operating the switch in the control device 201 .

In this way, when the state of any of the loading switch, the tailgate up switch, or the PTO switch changes, and when the manual transmission button is pressed in the event of an error, a transmission is made at any time, and the loading device is activated. Operating operation data such as the number of times, the number of times the tailgate is lifted, PTO connection, error information, safety device activation, etc. are transmitted to the specially equipped vehicle management server 100 .

In steps S19 and S21, it is determined whether or not Bluetooth connection is currently made with the control device 201, and if there is no connection, an alert is displayed. Accuracy is guaranteed. For example, when the user presses the send button at any time while away from the control device 201 when an error occurs, the user-worn device 160 receives the previous operating motion data rather than the operating motion data at the time when the error occurred. will be sent.

Therefore, by using the data accumulated in the user-specific operating motion data storage unit 26d of the specially equipped vehicle management server 100, when performing error analysis based on the operating motion data sent by the user using the send button as needed, it is possible to make an error analysis. This prevents the analysis from being performed incorrectly.

The accumulated operating motion data can be used for various analyses, as in the conventional case.

In this way, the user-worn device 160 transmits data received from the control device 201 to the specially equipped vehicle management server 100 at a predetermined timing. In this embodiment, the special purpose vehicle communication system has an antenna for Bluetooth connection in the cabin, so the connection between the control device 201 and the user-worn device 160 is less likely to be interrupted.

That is, the latest data is reliably accumulated in the operation data storage unit 126k of the user terminal device 160. FIG. The same applies to data transmission to the specially equipped vehicle management server 100 . Storing the latest data in the user-worn device 160 in this manner has the following advantages. For example, if it is determined that a temporary repair is sufficient according to the latest error message from the user portable device 160, such an instruction can be given from the user side administrator terminal device 120. FIG.

(6. Other Embodiments)
In this embodiment, Bluetooth (trademark) is used as near field communication, but other near field communication standards may be used.

In this embodiment, the antenna 65 is provided inside the near field radio unit 63 , but the antenna 65 may be provided outside the near field radio unit 63 .

Further, in the above embodiment, the antenna 65 is provided inside the cabin 302 . However, antennas 65 connected to short-range wireless units may be provided both inside and outside cabin 302 . This enables good communication both inside the cabin 302 and outside.

In this embodiment, in FIG. 3, the user terminals 150 of one user are illustrated as one user-side administrator terminal device 120 and one user-portable device 160, but the user-portable device 160 can be Required for the number of specially equipped vehicles to be used. In general, one user is composed of a plurality of user-portable devices 160 and a plurality of specially equipped vehicles. A plurality of user-side administrator terminal devices 120 may be provided.

In this embodiment, the user-mobile device 160 and the user-side manager terminal device 120 are logged in with the same user ID, but the worker and manager may have different user IDs. In this case, the IDs of the worker and the administrator may be related so that they can be registered in and read out from the same operating motion data for each user.

In this embodiment, since the garbage collection vehicle is adopted as the specially equipped vehicle, the operating operation data is the accumulated number of loading, the accumulated number of TG rises, the PTO operating time, and the position data. However, any data may be used as long as it is operation data of a specially equipped vehicle.
