Description

  The present invention relates to an anti-theft system that authenticates a driver's license and starts an engine and a work vehicle equipped with the anti-theft system, and more particularly to an anti-theft system and work vehicle used for vehicles such as automobiles and tractors.

  In recent years, from the viewpoint of preventing unauthorized use such as counterfeiting, an IC card license in which an IC chip in which information such as a name, a family register, a date of birth, and a license type is embedded is adopted as a driver's license. 2. Description of the Related Art Conventionally, it is known that a data reading device for a driver's license is provided in a vehicle, and the vehicle can run when it is determined that the vehicle can be driven from the data of the driver's license. Further, there has been proposed an apparatus that reads out data of a driving license without contact by electromagnetic induction action and issues an engine start permission (see Patent Document 1).

JP-A-7-150835

  However, the one described in Patent Document 1 allows the engine to be started only when the data code stored in the driver's license and the ID code set in advance on the vehicle side are collated and the collation is confirmed. It only increased the security, and the stored data of the driver's license was not used effectively elsewhere.

  Therefore, the present invention aims to provide a theft prevention system that solves the above-described problems by calculating the age of the driver from the information data of the driver's license and notifying the safety warning according to the age. To do.

According to the present invention, an engine mounted on a vehicle (5), a work machine (11) supported by a rear part of the vehicle (5) so as to be movable up and down, and reading means for reading information data of a driver's license (20) ( 17), a collation means (31) for collating and authenticating the information data with previously registered collation information, and an engine start permission means (32) for permitting the start of the engine when the information data is authenticated. In a work vehicle (1) having an anti-theft system comprising

  The driving operation unit 7 includes a driver seat 15 on which an operator is seated, a steering wheel 16 for steering the tractor 1, a main transmission lever (not shown), and the like. Further, an IC card reader 17 (reading means) is disposed on the side of the steering wheel 16, and the IC card reader 17 is a slot into which a driver's license 20 (see FIG. 2) made of an IC card can be inserted. have. By inserting the driver's license into the slot of the IC card reader 17, the name, full name, date of birth, date of license issuance, validity period, license type, etc. stored in the IC chip of the driver's license Although the information data can be read, the IC card reader 17 may be replaced with one that can read the information data without contact by electromagnetic induction.

  FIG. 2 shows a control block diagram of the tractor 1, and the tractor 1 has a control unit 19 composed of a microcomputer (including a CPU, ROM, RAM, etc.). On the input side of the control unit 19, an IC card reader 17 that reads information data stored in the driver's license 20 in a contact or non-contact manner, a timepiece 21 that measures time, and a vehicle speed that detects the vehicle speed of the body 5. A sensor 22, a steering angle sensor 23 for detecting the rotation angle of the steering wheel 16, a lift rod sensor 25 and a lift arm sensor 26 for detecting the expansion and contraction amounts of the lift rod and the lift arm, and the like are connected.

  On the output side of the control unit 19, a display device 27 including a liquid crystal monitor disposed in the driving operation unit 7, a lamp 29, a speaker 30, and the like are connected. The display 27, the lamp 29, and the speaker 30 constitute notification means. The control unit 19 registers authentication data (collation information) in advance, collates and authenticates the authentication data and information data recorded in the driver's license 20, and the collation unit 31. The engine start permission means 32 that permits the start of the engine, the age calculation means 33 that calculates the age of the driver who is the owner of the driver's license 20 from the information data, and the above And a registration unit 35 for registering authentication data in the verification unit 31. The authentication data is composed of, for example, two passwords consisting of four digits that are set when a driver's license is acquired / updated.

  Next, the registration of authentication data in the verification unit 31 by the registration unit 35 will be described with reference to FIGS. 3 and 4. FIG. 3 shows a flow of registration of the first authentication data. First, the driver's license 20 is inserted into the IC card reader 17 (step S1), and the information data of the driver's license 20 is read (step S2). . At the same time, authentication data is entered from the display device 27, for example (step S3), and the information data is compared with the authentication data (step S4).

  If these data match (step S5: Yes), the authentication data set in the verification means 31 is registered (step S6), and the process returns to the beginning (step S7). If the information data and the authentication data do not match (step S5: No), the process returns to the beginning (step S7). In the data comparison in step S5, if the license type in the information data of the driver's license 20 does not match the vehicle (the tractor in the present embodiment), the authentication data cannot be registered. (It is the same in step S12 described later). Thereby, when a license other than a normal license is required for a large vehicle, a large special vehicle, etc., it is possible to prevent accidental driving without a license.

  FIG. 4 shows a flow for registering the second and subsequent authentication data. First, the driver's license 20 is inserted into the IC card reader 17 (step S8), and the information data of the driver's license 20 is read (step S9). ). Then, the authentication data already set and registered is read (step S10), and the information data is compared with the authentication data (step S11).

  If these data match (step S12: Yes), for example, new authentication data is set from the display device 27 (step S13), and the authentication data is registered in the verification means 31 (step S14). Return (step S15). If the information data does not match the authentication data in step S12 (step S12: No), the process returns to the beginning (step S15). As a result, new authentication data can be additionally registered for the first time in a state where the information data of the driver's license 20 has been authenticated by the authentication data already set and registered, so that the security effect is not reduced, and the tractor Two or more drivers can be registered in one.

  Next, control after authentication of the driver's license 20 will be described with reference to FIG. First, the driver's license 20 is inserted into the IC card reader 17 (step S16), and the information data of the driver's license 20 is read (step S17). The authentication data already set and registered is read (step S18), and the information data is compared with the authentication data (step S19).

  If these data do not match (step S20: No), the process returns to the beginning (step S21). If the information data and the authentication data match in step S20 (step S20: Yes), the engine start permission means 32 outputs a signal for permitting the tractor 1 to start the engine. As a result, the engine can be started keylessly, and theft can be prevented by limiting the driver.

  Then, the age calculating means 33 calculates the current age and driving carrier of the driver from the date of birth information and the date of license issuance of the driver's license 20 (step S23), and returns to the beginning (step S23). S24).

  Next, a control flow for each driving carrier will be described with reference to FIG. First, it is checked from the license promulgation date information whether the license has been acquired for a predetermined number of years (for example, 3 years) or more (step S25). If the license acquisition year is less than the predetermined year (step S25: No), the beginner mode is started (step S26), and the process returns to the beginning (step S27).

  If the number of years of license acquisition is equal to or greater than the predetermined number of years (step S25: Yes), it is checked from the date of birth information whether the current age is 65 years or older (step S28). If the age is less than 65 years (step S28: No), the veteran mode is started (step S29), and the process returns to the beginning (step S27). If the age is 65 years or older (step S28: Yes), the elderly person mode is started (step S30), and the process returns to the beginning (step S27).

  As shown in FIG. 7, the beginner mode, the veteran mode, and the elderly mode have different tolerances for working speed, traveling speed, work implement lifting speed, and rest time according to each mode. Is exceeded, a safety warning is notified by the display 27, the lamp 29, and the speaker 30. For example, in the beginner mode and the elderly mode, when the working speed and the running speed exceed the medium speed, the display 27 and the speaker 30 notify the display 27 and the speaker 30 with a warning “Please reduce the speed.” Is done. Similarly, when the work implement ascending / descending speed exceeds the medium speed, the display 27 and the loudspeaker 30 are notified of a display and sound safety warning “Please lower the work implement elevating speed”.

  In the beginner mode and the elderly mode, when the driving time or work time exceeds 1 hour, the display 27 and the speaker 30 are notified of a display and a voice saying “It is time for a break soon”. These displays may be performed by the lamp 29. Similarly, in the veteran mode, when the working speed is high, the traveling speed is high, the working equipment lifting speed is high, and the operation time or working time exceeds two hours, a safety warning is given from the display device 27 and the speaker 30. Informed. In addition, even when the engine is stopped for a short time, such as a toilet break, the measurement of the operation time or the work time may be made to notify a safety warning by measuring the accumulated operation time without clearing the measurement time.

  Moreover, the warning timing of these working speeds, traveling speeds, working machine ascending / descending speeds, and break times (driving hours) can be set freely, and is not limited to the present embodiment. Further, other warnings may be issued, for example, warnings according to the driving carrier may be issued for the inter-vehicle distance, the sudden handle, the sudden brake, or the like.

  The anti-theft system including the engine, the IC card reader 17, the control unit 19 and the like restricts the driver of the tractor 1 to prevent the anti-theft, while the engine is being driven and information on the driver's license 20 Safety warnings according to age and driving carrier can be notified from the data to improve safety.

  The anti-theft system can be applied not only to a tractor but also to other work vehicles such as a combiner and a transplanter, and can be appropriately changed to a warning according to the work contents of the work vehicle.
