Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to an anti-theft device for a moving object that is provided in a moving object driven by an engine such as a working machine such as a hydraulic shovel and enables the operation of the moving object only when a predetermined condition is satisfied.
[0002]
[Prior art]
As this kind of related art, for example, the following first to third related arts are known.
[0003]
The first prior art is provided with a password authentication means, in which a moving body is a hydraulic machine such as a hydraulic shovel, that is, a working machine, and a password is stored in a control device provided in the hydraulic machine in advance, and a numeric keypad or the like is used. The security code is input from the input device, the stored security code is compared with the security code input from the input device, and when they match, the engine starter is energized and the engine can be operated. It is to be. According to this conventional technique, only a person who knows the password can drive the engine, reject the operation of the hydraulic machine by a third party who does not know the password, and prevent theft of the hydraulic machine. (For example, refer to Patent Document 1).
[0004]
The second related art includes an ID collation authentication unit, in which a moving object is a vehicle, and reads an ID code that is a specific code specific to an ignition key of the vehicle, that is, an engine start key, and reads a specific code stored in advance with a specific code. The data is collated, and a power-on signal is output when they match. Therefore, the power can be turned on only by the key on which the specific code is written, and the vehicle can be prevented from being stolen by a third party who does not own the key on which the specific code is written (for example, see Patent Document 1). 2).
[0005]
The third related art includes a position authentication unit, in which a moving body is a construction machine such as a hydraulic shovel, and a workable area of the construction machine is set in advance, and a position of the construction machine is determined by using a GPS (Global Positioning System). When the measured position of the construction machine is outside the set workable area, that is, when the measured position of the construction machine does not match the set workable area, the operation stop signal is transmitted to the construction machine. . For this reason, when the stolen construction machine comes out of the set workable area, the construction machine cannot be operated. This contributes to the prevention of theft of the construction machine (for example, see Patent Document 3).
[0006]
As described above, in order to prevent theft of a construction machine operating at a work site, that is, a moving body driven by an engine such as a work machine or a vehicle, various techniques including authentication means have been conventionally proposed.

[Problems to be solved by the invention]
By the way, the above-mentioned first related art is provided with a password authentication means, that is, a device which uses a password to prevent the hydraulic machine from being stolen. In addition, problems related to the operation of the hydraulic machine occur. For example, a hydraulic machine owned by a rental company may be lent to an unspecified number of contractors. In such a case, the password of the lent hydraulic machine may be changed on the contractor side. When the password is changed in this way, after the hydraulic machine is returned to the rental company, there is a possibility that a person on the rental company side cannot operate the hydraulic machine without knowing the password. After the hydraulic machine is stolen by some illegal means, it is possible that the hydraulic machine can be driven.
[0011]
Further, the above-mentioned second prior art is provided with an ID collation and authentication means, that is, a method of preventing a vehicle from being stolen by assigning a specific code to the ignition key. However, if the corresponding ignition key is lost. If the vehicle is stolen, the vehicle may not be able to move. In the second prior art, similarly to the first prior art, after the vehicle is stolen by some illegal means, it is possible that the vehicle can be driven.
[0012]
Further, the above-described third conventional technique is provided with a position authentication unit, that is, an operable area is set, and the construction machine is stolen by utilizing GPS. According to the third conventional technique, when the construction machine is out of the operable area after the construction machine is stolen, the construction machine becomes inoperable, so that it is effective in preventing theft from that viewpoint. However, as in the first and second prior arts described above, theft itself cannot be prevented. That is, the technology is based on the assumption that the device is stolen.
[0013]
As described above, the first to third prior arts are effective in preventing theft under respective unique conditions, but have a drawback in their responsiveness when some special situation occurs.
[0014]
SUMMARY OF THE INVENTION The present invention has been made in view of the above-described state of the art, and an object of the present invention is to provide an anti-theft device for a mobile object which has excellent responsiveness in various situations.
[0015]
[Means for Solving the Problems]
In order to achieve the above object, the present invention provides an electric functional component that electrically controls the operation of a moving body driven by an engine, an input unit that inputs a predetermined signal, and a predetermined input that is input to the input unit. An authentication unit having a matching unit for checking whether the signal matches a preset condition, and outputting a match signal when the signal matches, and the electric functional component when the match signal is output from the authentication unit. Unlocking means for outputting an unlock signal to enable the operation of the moving body, and when the coincidence signal is not output, not outputting the unlocking signal to the electric functional component and disabling the operation of the moving body. In the mobile object anti-theft device comprising: a plurality of the authentication means, and the unlocking means, each set value corresponding to a plurality of coincidence signals output from each of the plurality of authentication means, A setting unit that can be set, and an unlocking signal output unit that outputs the unlocking signal when all of the plurality of coincidence signals match each of the setting values set by the setting unit. It is characterized by:
[0016]
In the present invention configured as described above, for example, a plurality of set values are set in advance in the setting unit of the unlocking means. One of these set values is a first set value corresponding to a coincidence signal output from the first authentication means of the plurality of authentication means, and the other one is output from the second authentication means. Is the second set value corresponding to the coincidence signal to be obtained. Each of the first authentication means and the second authentication means has a different type of a predetermined signal input to the input unit, and accordingly, a condition used for matching, that is, a preset condition is different.
[0017]
As described above, for example, the first setting value corresponding to the coincidence signal output from the first authentication unit and the second setting value corresponding to the coincidence signal output from the second authentication unit are set in the setting unit. In a state where a predetermined signal related to the first authentication unit is input to the input unit of the first authentication unit and the predetermined signal is matched by the matching unit with a condition set in advance, A match signal is output. Similarly, a predetermined signal related to the second authentication unit is input to the input unit of the second authentication unit, and when the predetermined signal matches the predetermined condition with the matching unit, the matching signal is determined. A signal is output. When each of the coincidence signals output from the first and second authentication means matches the first set value and the second set value set by the setting section, an unlock signal output section of the unlock means is provided. Outputs an unlock signal to the electrical functional component. Thereby, the electric functional component is controlled so that the moving body can be operated.
[0018]
If the coincidence signal output from each of the first and second authentication means does not match any one of the first and second set values, the unlock signal is output from the unlock signal output unit. However, the electric functional component controls the operation of the moving object to be disabled. This can prevent the moving body from being stolen.
[0019]
Then, for example, when a trouble situation peculiar to the first authentication unit occurs, only the set value corresponding to the coincidence signal according to the second authentication unit is reset to the setting unit, and the second authentication unit is set. What is necessary is just to input the related predetermined signal to the input part of the said 2nd authentication means. As a result, since the coincidence signal output from the second authentication unit matches the set value set by the setting unit, the unlocking signal is output from the unlocking signal output unit to the electric functional component, and the operation of the moving body is stopped. This makes it possible to cope with a trouble situation or the like unique to the first authentication unit.
[0020]
The same applies to the case where an inconvenient situation specific to the second authentication means has occurred. In such a case, only the set value corresponding to the coincidence signal according to the first authentication means is reset in the setting section, and the first What is necessary is just to input a predetermined signal related to the authentication unit to the input unit of the first authentication unit. As a result, since the coincidence signal output from the first authentication unit matches the set value set by the setting unit, the unlocking signal is output from the unlocking signal output unit to the electric functional component, and the operation of the moving body is stopped. This makes it possible to cope with a trouble situation or the like unique to the second authentication unit.
[0021]
Also, for example, first, second, and third authentication means are provided as a plurality of authentication means, and under certain circumstances, the first and second set values corresponding to the first and second authentication means are reset in the setting section. The matching signal output from each of the first and second authentication means is compared with each of the first and second set values, and in another situation, the third setting corresponding to the third authentication means is made. Only the value may be reset in the setting unit, and the operation of the moving body may be controlled by comparing the coincidence signal output from the third authentication unit with the third set value.
[0022]
As described above, the present invention is effective in preventing theft and can ensure excellent responsiveness in various situations.
[0023]
Further, according to the present invention, in the above invention, the setting unit includes a specification unit for specifying the set value, and a storage unit rewritable in accordance with the set value specified by the specification unit.
[0024]
Also, in the present invention according to the above invention, the plurality of authentication means may be configured such that the preset condition is an operable area of the moving object, and the input unit receives signals from a plurality of artificial satellites and receives position information. The position authentication means, which is a GPS receiver for converting into a password, the predetermined condition is a password, and the input unit is a number input unit for inputting a password, and the password authentication unit, The condition is that the ID information is provided in an ignition key for starting the engine, and that the input unit includes at least two authentication means of ID collation authentication means which is ID reading means for reading the ID information of the ignition key.

[0055]
As described above, when the ignition key 5 is inserted and the key is turned on, the operable area stored in the EEPROM 23 is first read as shown in step S20, and the process proceeds to step S21. In step S21, a signal from the GPS artificial satellite 50 is input via the GPS receiver 22, and the current position of the excavator, that is, the latest position, is calculated based on the GPS signal. Next, the procedure moves to step S22, and it is determined whether or not the latest position obtained in step S21 is within the operable area read in step S20. That is, it is determined whether the current position matches the operable area. If it is determined that they match, the procedure moves to step S23.

As described above, when the ignition key 5 is inserted into the key-on state, the personal identification number stored in the EEPROM 33 is read as shown in the first step S30, and the process proceeds to step S31. In this step S31, the personal identification number output by the operation of the operation device 32a by the operator is input via the number input unit 32. Next, the procedure proceeds to step S32, where it is determined whether or not the password input by the operator matches the password stored in the EEPROM 33 read in step S30. If it is determined that the numbers match, the process proceeds to step S33. In this step S33, a process of outputting a number coincidence signal to the unlocking means 10 via the digital output device 39 is performed. If it is determined in step S32 that the numbers do not match, the process ends without causing the unlocking means 10 to output a number match signal.
[0058]
[Operations in ID collation authentication means]
FIG. 7 is a flowchart showing a processing procedure in the CPU 47 of the ID collation / authentication unit 40 shown in FIG.
[0059]

It is determined whether or not. If it is determined that they match, the procedure moves to step S42. In this step S42, a process of outputting an ID coincidence signal to the unlocking means 10 via the digital output device 48 is performed. If it is determined in step S41 that they do not match, the process ends without causing the unlocking means 10 to output an ID match signal.
[0060]
[Operations in unlocking means]
FIG. 9 is a flowchart showing a processing procedure in the CPU 16 of the unlocking means 10 shown in FIG.
[0061]
For example, when the ignition key 5 is inserted and the key is turned on, as shown in step S10, a set value corresponding to the coincidence signal stored in the EEPROM 12 is read, and the process proceeds to step S11. In this step S11, it is determined whether or not a coincidence signal input via the digital input device 11, that is, an operation area coincidence signal, a number coincidence signal, and an ID coincidence signal exists. When it is determined that the coincidence signal exists, the process proceeds to step S12. When it is determined that there is no coincidence signal, the process returns to the initial step S10.
[0062]
In step S12, it is determined whether or not the coincidence signal whose existence has been confirmed in step S11 matches the set value stored in EEPROM 12 read in step S10. In this case, when the presence of a plurality of matching signals is confirmed in step S11, it is individually determined in step S12 whether each of the plurality of matching signals matches the corresponding set value. If it is determined in step S12 that the input match signal matches the set value, for example, if it is determined that each of the plurality of match signals and all the corresponding set values match, the process proceeds to step S13. In this step S13, a process of outputting an unlocking signal to the starter control circuit 2 and the hydraulic control circuit 7 via the digital output device 17 is performed. If it is determined in step S12 that they do not match, the process returns to step S10.
[0063]
FIG. 10 is a diagram showing a configuration of the EEPROM 12 included in the unlocking means 10 shown in FIG.
[0064]
As shown in FIG. 10, the EEPROM 12 is composed of, for example, an 8-bit memory, and when the password authentication unit 30 is designated by the setting unit 19, the least significant bit D0 includes a set value related to the number match signal, that is, a flag. “1” is set. When the ID collation / authentication unit 40 is designated by the setting unit 19, a set value related to the ID coincidence signal, that is, a flag “1” is set in the next bit D1. Further, when the position authentication means 20 is designated by the setting device 19, a setting value relating to the operation area coincidence signal, that is, a flag "1" is set in the next bit D2.
[0065]
[Usage example 1 of this embodiment]
For example, a construction company rents a hydraulic shovel having one embodiment of the anti-theft device of the present embodiment from a rental company, and uses the setting device 19 shown in FIG. It shall be specified.
[0066]
As a result, in the EEPROM 12 of the unlocking means 10, the set values, that is, the flag “1” are set in the bit D0 and the bit D2 as described above.
[0067]
When the installer enters the correct password in a state where the above-mentioned hydraulic excavator is placed in the workable area, the number matching signal and the operating area matching signal are output from the password authentication means 30 and the position authentication means 20, respectively. Is entered. The CPU 16 of the unlocking means 10 reads each of the set values stored in the EEPROM 12, that is, the flag "1" of the bit D0 and the flag "1" of the bit D2, and inputs the number match signal and the operation area match signal. To each of Now, since both of them match, the unlock signal is output from the digital output device 17 to the starter control circuit 2 and the hydraulic control circuit 7.
[0068]
As a result, the starter control circuit 2 connects the starter 3 and the battery 6 as described above, and enables the start of an engine (not shown). Further, the hydraulic control circuit 7 supplies a drive current to the hydraulic control electromagnetic valve 8 so that various actuators of a working machine such as a boom and an arm can be operated. Therefore, the contractor drives the engine and operates the operating device related to each actuator, whereby the hydraulic oil from the hydraulic pump is supplied to the corresponding actuator, and the desired work such as excavation work including running and turning operations is performed. Can be implemented.
[0069]
Also, if a person who steals the ignition key 5 related to the above-mentioned hydraulic excavator inserts the ignition key 5 into the key cylinder 4 and tries to steal the hydraulic excavator, if he does not know the personal identification number, the personal identification code from the personal identification number authenticating means 30 is required. The number is not input to the unlocking means 10. As a result, the comparisons in the CPU 16 of the unlocking means 10 do not all match, and the unlock signal is not output from the digital output device 17. Therefore, the engine cannot be driven, and the operation of the working machine is disabled, so that the hydraulic shovel can be prevented from being stolen.
[0070]
Further, even if the excavator is taken out of the workable area by some means with the intention of stealing the excavator, the operating area coincidence signal from the position authentication means 30 is not input to the unlocking means 10 in this state. As a result, the collation in the CPU 16 of the unlocking means 10 does not match, and the unlock signal is not output from the digital output device 17. Therefore, also in this case, the engine cannot be driven, and the operation of the work implement becomes impossible. Therefore, it is effective in preventing the excavator from being stolen.
[0071]
When the hydraulic excavator used by the contractor in the workable area is returned to the rental company as described above, the rental company sets, for example, only the bit D1 by the setting device 19, that is, the flag “ An operation of setting "1" and resetting the flags of the other bits D0 and D2 to "0" is performed. As a result, only the ID match signal output from the ID collation / authentication unit 40 becomes valid. Therefore, on the rental company side, regardless of the presence / absence of the coincidence signal from the personal identification number authenticating means 30 and the position authenticating means 20, the engine can be driven and run only by inserting the ignition key 5 in which the ID information is written into the key cylinder 4. In addition, it is possible to drive a working machine or the like including a turning operation, and the excavator can be easily moved to a predetermined delivery place.
[0072]
As described above, in the above-mentioned utilization example 1, while having the two anti-theft functions relating to the personal identification number and the position information of the excavator, the operation of the excavator in the rental company can be easily performed. Excellent responsiveness.
[0073]
[Usage example 2 of this embodiment]
Further, for example, in the hydraulic excavator provided with the anti-theft device of the present embodiment, the setting device 19 shown in FIG. 8 specifies the password authentication unit 30, the ID verification authentication unit 40, and the position authentication unit 20. I do.
[0074]
As a result, in the EEPROM 12 of the unlocking means 10, the set values corresponding to the bit D0, the bit D1, and the bit D2, that is, the flag “1” are set.
[0075]
With the excavator arranged in the workable area, a correct password is input, and the ignition key 5 on which the ID information is written is inserted into the key cylinder 4, and the reef number authentication means 30, the ID verification authentication means 40, The number matching signal, ID matching signal, and operating area matching signal from each of the authentication means 20 are input to the unlocking means 10. The CPU 16 of the unlocking means 10 reads and inputs each of the set values stored in the EEPROM 12, that is, the flag “1” of the bit D0, the flag “1” of the bit D1, and the flag “1” of the bit D2. The number matching signal, the ID matching signal, and the operating area matching signal are individually collated. Now, since all of them match, the unlock signal is output from the digital output device 17 to the starter control circuit 2 and the hydraulic control circuit 7. Therefore, as described above, the engine and the working machine including the traveling and turning operations can be driven, and desired work can be realized.
[0076]
Here, it is assumed that, for some reason, for example, the ignition key 5 on which the ID information is written is lost and the hydraulic shovel cannot be moved. That is, even if a correct password is input in a state where the ignition key 5 on which the ID information is written is not inserted into the key cylinder 4 and another ignition key or the like on which the ID information is not written is inserted, the unlocking is performed. The collation of the CPU 16 in the means 10 does not match, the unlock signal is not output from the digital output device 17 to the starter control circuit 2 and the hydraulic control circuit 7, and the driving of the engine and the working machine including running and turning operations are impossible. Is kept.
[0077]
When such an unexpected situation occurs, for example, the setting value of only the bit D0, that is, the state where the flag “1” is set by the setting unit 19, and the flags of the other bits D1 and D2 are set to “0” An operation is performed again. Thus, the engine and the working machine can be driven only by inputting the correct password, and the hydraulic excavator can be operated.
[0078]
As described above, in the utilization example 2 described above, the ignition key 5 having the ID number, the ID information written therein, and the three anti-theft functions relating to the ID information of the ignition key 5 and the position information of the excavator are provided. In the event of loss, the excavator can be operated by inputting a password, and has excellent durability in response to unexpected situations.
[0079]
That is, in the above-mentioned utilization example 2, while ensuring the three anti-theft functions relating to the password, the excavator position information, and the ID information of the ignition key 5, excellent responsiveness according to the situation is obtained. Have.
[0080]
As described above, the present embodiment has excellent responsiveness to various situations while ensuring the anti-theft function, and can realize multi-function.
[0081]
In the first application example, the password authentication unit 30 and the position authentication unit 20 are designated by the setting unit 19 of the release unit 10. In the utilization example 2, the password authentication unit 30 and the ID are identified by the setting unit 19. Although the three authentication means 40 and the location authentication means 20 are designated, the setting device 19 designates the password authentication means 30 and the ID verification authentication means 40, and the password identification signal and the ID matching signal are matched. You may make it collate by CPU16 based on a signal. In this case, the position authentication unit 20 may not be provided.
[0082]
Alternatively, the setting unit 19 may specify two of the ID collation / authentication unit 40 and the position authentication unit 20, and the CPU 16 may collate based on the ID coincidence signal and the operation area coincidence signal. In this case, the transmitter 41 and the ID collation / authentication unit 40 may not be provided.
[0083]
【The invention's effect】
Since the present invention has the above-described configuration, the present invention has excellent responsiveness in various situations while securing the anti-theft function, thereby realizing multi-functions that could not be realized conventionally.
