Hereinafter, an embodiment of the present invention will be described with reference to the drawings.
[0011]
As shown in FIG. 1, information on the vehicle 11 side transmitted from a vehicle 11 such as a construction machine vehicle (for example, a hydraulic excavator or a bulldozer) having a communication function is transmitted remotely via a communication line such as a communication satellite 12. The data is received by the local communication base station 13, further sent to the management department 14, and managed by the communication base station 13 and the management department 14.
[0012]
On the other hand, information transmitted from the management department 14 via the communication base station 13 is received by the vehicle 11 via the communication satellite 12. The communication base station 13 and the management department 14 are collectively referred to as a management station 15.
[0013]
As shown in FIG. 2, the vehicle 11 is equipped with a controller 21 such as a body controller for electronically controlling the engine speed of the vehicle 11, the discharge pressure / discharge flow rate of the hydraulic pump, the body operation, and the like. .
[0014]
The controller 21 is a computer including a central processing unit (CPU), a read only memory (ROM), a random access memory (RAM), a non-volatile memory (EEPROM, etc.), and the like.
[0015]
Further, the controller 21 of the vehicle 11 has a function of collecting or transmitting external information and airframe information, and the controller 21 is connected to a transmitter / receiver 22 as a communication means for transmitting / receiving the information. In addition, a global positioning system device (hereinafter referred to as “GPS23”) is connected as a vehicle position measuring means for acquiring its own position information.
[0016]
Furthermore, a power supply 24 for the controller 21 is connected to the controller 21 of the vehicle 11, and a keyboard or keypad for inputting sensors 25, identification numbers and the like of each part of the fuselage to the input part of the controller 21. In addition to the display device 27, the solenoid of the solenoid valve 28 provided in the hydraulic system and fuel system circuit, etc., the hydraulic device is connected to the output unit of the controller 21, etc. An operation valve for piloting the control valve 31 of the device control system, that is, a solenoid 33 for locking the remote control valve 32 to the neutral position, a solenoid 35 for locking the safety lever 34 to the safety position, and the like are connected.
[0017]
A solenoid 33 that locks the remote control valve 32 in the neutral position and a solenoid 35 that locks the safety lever 34 in the safety position are antitheft means for preventing the vehicle 11 from being stolen. A switch 36 for cutting off the power supply 24 of the device 21 and the monitor 27 is provided.
[0018]
With these antitheft means, for example, by locking the remote control valve 32 to the neutral position by the solenoid 33, the traveling hydraulic motor such as a hydraulic excavator, the working machine hydraulic motor and the hydraulic cylinder cannot be operated, and the vehicle theft Block or limit.
[0019]
The transmitter / receiver 22 as a communication means of the vehicle 11 receives the vehicle identification information assigned to the vehicle together with the personal identification information and password identification information of the vehicle owner input from the input device 26 when starting the vehicle 11. It can be sent. The personal identification information and the password identification information are input from the input device 26. However, the vehicle identification information is vehicle-specific identification information built in the vehicle 11, and does not need to be input from the input device 26.
[0020]
As the password identification information, a one-time password displayed on a one-time password medium 37 such as a one-time password card that generates and displays new identification information as time passes is used.
[0021]
This one-time password medium 37 is synchronized with a system clock common to the server 38 of the communication base station 13, automatically generates a new password with the passage of time, and displays the password at that time on the card display screen. Since it has a function and the password is rewritten and changed randomly over time, even if the one-time password is stolen, the password once used cannot be used, so it has excellent confidentiality .
[0022]
Further, since the one-time password medium 37 can be managed by the server 38, the loss of the medium 37 can be dealt with. For example, it is excellent in confidentiality because it is possible to avoid the abuse of the one-time password by receiving the notification of the card loss and invalidating the card.
[0023]
As the one-time password medium 37, there is a key holder type in addition to the one-time password card, which may be used.
[0024]
On the other hand, the communication base station 13 has a password such as a one-time password transmitted from the vehicle 11, identification information assigned to the vehicle 11 (ie, vehicle identification information) and vehicle owner identification information (ie, personal identification information). A server 38 for monitoring the vehicle 11 is received by receiving identification information including, and collating it with identification information held by itself.
[0025]
The server 38 has a function of automatically rewriting and changing the identification information in conjunction with the one-time password medium 37.
[0026]
That is, this server 38 has a system clock synchronized with a clock built in the one-time password medium 37, and personal identification information from a password sent from an authorized vehicle user who has received permission from the vehicle owner, By searching for card-specific information and deviation information, a plurality of token codes at the current time and a fixed time before and after the current time and the token code generation algorithm are generated, and the server 38 generates a plurality of token codes. The token code and the token code generated by the one-time password medium 37 at the time of authentication and sent to the server 38 through the transmitter / receiver 22 and the communication satellite 12 of the vehicle 11 are collated, and authentication processing is performed to determine whether or not they match. Authentication server 38 of the time synchronization method.
[0027]
This time-synchronized authentication has the advantage that operability is very easy for a regular vehicle user.
[0028]
This authentication method has excellent confidentiality by rewriting the identification information of the one-time password medium 37 and the identification information of the server 38 at random. In addition, since the management information of the one-time password medium 37 is managed by the server 38, it is possible to cope with the loss of the medium 37, so that the confidentiality is excellent.
[0029]
The verification by the server 38 may be performed by the management department 14 connected to the communication base station 13 by wire. Hereinafter, the communication base station 13 or the management department 14 is referred to as a management station 15.
[0030]
And three types of identification information: vehicle identification information allocated to the vehicle 11, personal identification information of the vehicle owner, and identification information (one-time password) on the one-time password medium 37 that is also owned and generated by the management station 15 After establishing the relationship between the vehicle 11, the authorized vehicle user authorized by the vehicle owner, and the management station 15, the server 38 of the management station 15 collates, so that Monitoring is easy and reliable. In particular, by using the management station 15 at the initial stage of verification, a quick and reliable response can be made when a problem occurs.
[0031]
For example, if there is a collation from an unauthorized user to the vehicle 11 that has been notified of theft to the management department 14 of the management station 15, the remote operation signal transmitted from the management station 15 to the vehicle 11 via the communication satellite 12 To lock the remote control valve 32 of the vehicle 11, that is, lock the operation lever, lock the safety lever 34, warn the display screen of the monitor 27, stop the on-vehicle program (for example, no display on the display screen of the monitor 27) The anti-theft means such as termination of the on-board program (for example, shutting down the power of the controller 21 and the monitor 27 due to shutdown, etc.), or any or all of the three types of identification information are invalidated by the server 38 Can limit or stop the operation of the aircraft.
[0032]
Further, when the identification information is collated by the server 38 of the management station 15 using the position information of the vehicle 11 acquired by the GPS 23 sent together with the identification information, the position information of the vehicle 11 is added and monitored. For example, if there is an illegal collation from a vehicle that has been notified of theft to the management station 15, the vehicle 11 is recognized as a stolen vehicle, and the vehicle identification information and the GPS23 position information You can quickly identify, report, and locate a place.
[0033]
Next, the control procedure of the embodiment shown in FIGS. 1 and 2 will be described with reference to the flowchart shown in FIG. The circled numbers in the figure indicate step numbers.
[0034]
As shown in FIG. 3, the power supply 24 of the vehicle 11 is turned on by a key-in operation (step 1), the identification information assigned to the vehicle 11 (vehicle identification information, that is, the machine code), and the vehicle ownership input from the input device 26 Identification information (personal identification information) and identification information (one-time password) generated and displayed by the one-time password medium 37 possessed by the authorized vehicle user are input to the controller 21 of the vehicle 11 (step 2) The position information of the vehicle 11 is acquired by the GPS 23 (step 3), and the identification information and the position information are transmitted from the transceiver 22 of the vehicle 11 to the communication base station 13 via the communication satellite 12 (step 4).
[0035]
In the communication base station 13 that has received the information, the server 38 verifies the identification information (step 5).
[0036]
Then, the server 38 determines whether or not the identification information transmitted from the vehicle 11 side matches the identification information of the server 38 (step 6). If they match (YES in step 6), further The search for a theft report to the vehicle 11 being verified is performed to determine whether a theft report has been issued (step 7). If the theft report has not been issued (NO in step 7), the communication base Since a permission signal is transmitted from the station 13 to the vehicle 11 via the communication satellite 12 (step 8) and the antitheft means is not functioned (step 9), the engine can be started to move the aircraft.
[0037]
On the other hand, if the identification information does not match in step 6 (NO), or if a theft notification has been issued in step 7 (YES), a non-permission signal is sent from the communication base station 13 to the vehicle 11 via the communication satellite 12. The information is transmitted (step 10), and the discovery of the stolen vehicle is notified to the management department 14 together with the vehicle identification information and position information (step 11).
[0038]
The vehicle 11 receives the non-permission signal from the communication base station 13 and causes the antitheft means to function (step 12). Therefore, it is possible to prevent the vehicle 11 from being stolen and to prevent the use of the stolen vehicle. In addition, when a legitimate vehicle user inputs the identification information by mistake, it may be redone from the key-in operation.
[0039]
As described above, when starting the vehicle 11 having the communication function, the vehicle owner identification information is input to the vehicle 11, and the identification information assigned to the vehicle 11 from the vehicle 11 and the vehicle owner identification information are managed. The vehicle 11 monitoring method for monitoring the vehicle 11 by collating the identification information assigned to the vehicle 11 by the management station 15 with the identification information of the vehicle owner and the identification information held by the management station 15 By making the relationship between the vehicle 11, the vehicle owner, and the management station 15, monitoring by the management station 15 is easy and reliable, and in particular, the identification information can be collated by the management station 15 in the initial stage. Thus, for example, when a problem occurs such as when an unauthorized user collates the vehicle 11 for which the theft notification has been sent to the management station 15, a quick and reliable response can be made.
[0040]
The vehicle 11 is a monitoring method having a function of acquiring its own location information and transmitting it to the management station 15. When the management station 15 collates the identification information, the vehicle 11 is added with the location information and monitored. For example, when there is a verification from a vehicle that has been notified of theft to the management station 15, the antitheft means is operated as a stolen vehicle, and the location of the stolen vehicle is specified and easily found. Can do.
[0041]
Furthermore, the monitoring method that includes the one-time password that rewrites and changes the identification information as time elapses in the identification information used for verification uses a public line such as the communication satellite 12 because the identification information is rewritten and changed as time elapses. Even confidentiality is excellent.
[0042]
As the identification information input means for inputting the identification information of the authorized vehicle user or vehicle to the vehicle 11 when starting the vehicle 11, for example, a lever pattern input method using a lever of a construction machine vehicle, or a construction machine vehicle The identification information may be input and collated by the license key code input method of the software installed in the computer.
[0043]
The lever pattern input method is that the standard airframe is equipped with two left and right control levers and two left and right travel levers, so a predetermined lever after the engine key is turned on and before the engine is started. The lever pattern is input by operating. For example, pattern input is performed by tilting the right operating lever once before, once after, and by tilting the left operating lever twice to the right and three times to the left. It is verified whether or not this operation matches a predetermined operation.
[0044]
The license key code input method is that the standard aircraft is equipped with software for controlling the aircraft in the controller. Therefore, an individual license key code is written in this software in advance and the engine key is entered. A predetermined code is input after turning on the engine and before starting the engine. For example, when the license key code is determined to be “ABCD”, “ABCD” is input using the input device 26 such as a keyboard. Check if this code matches.
[0045]
Finally, the present monitoring system is not limited to construction machinery vehicles, and can be applied to vehicles such as passenger cars and transport vehicles such as dump trucks.
