Description
Technical field
The present invention relates to the anti-joyride device of the construction machinery and equipments such as hydraulic excavator.
Background technology
The construction machinery and equipment of hydraulic excavator etc. has anti-joyride device conventionally, and this anti-joyride device makes mechanical action become illegal state when the non-action of machinery, when machinery starts, illegal state is removed.For example, the anti-joyride device of recording in patent documentation 1 is provided with ten key input media, by this ten key input media input password, when consistent based on checking of password, removes the illegal state of the action of construction machinery and equipment, and driving engine can start.The anti-joyride device of recording in patent documentation 2 is provided with communicator, by this communicator input password, when consistent based on checking of password, removes the illegal state of the action of construction machinery and equipment, and driving engine can start.
But in recent years, the running truth of the construction machinery and equipments such as hydraulic excavator is, the form that lease dealer buys in a large number construction machinery and equipment and is leased to as required the client who carries out civil construction etc. becomes main flow.In this case, dealer is as supvr in lease, wishes to carry out uniformly the safety management of a plurality of construction machinery and equipments, and on the other hand, all inputs safety management loaded down with trivial details of password while wishing to avoid starting operation as client's operator at every turn.Under such background, in patent documentation 3, record following anti-joyride device,, communicator is set on anti-joyride device, supvr sets the locking zero hour and the latch-release moment at manager terminal, if send and set instruction to being located at communicator on anti-joyride device, receive set instruction and specific time band (from locking zero hour of setting to latch-release constantly) in become the lock-out state (illegal state) of the action of forbidding construction machinery and equipment.
In addition, in patent documentation 3, the scheme of following anti-joyride device has also been proposed, that is, and in order to tackle randomly according to operation situation, in supvr's side, set starting caging time and the latch-release moment, if send setting instruction to the communicator being located on anti-joyride device, receive and set instruction and make construction machinery and equipment become lock-out state, and, further before starting and will passing through caging time, repeatedly set instruction reception until latch-release constantly.
Patent documentation 1: Japanese kokai publication hei 9-50584 communique
Patent documentation 2: TOHKEMY 2005-255094 communique
Patent documentation 3: TOHKEMY 2003-34232 communique
Yet, two kinds of anti-joyride devices recording in patent documentation 3 are all that mechanical action is become to the anti-joyride device that the time band (be carved into from the outset and remove constantly) of illegal state is set, therefore,, the in the situation that operation not being carried out according to plan in construction, can produce following problem.For example, in operation than plan finish ahead of time in the situation that, until before locking zero hour of setting during in do not lock, safety reduces.And, in order to change the beginning period of locking in supvr's side, supvr sends and sets instruction after operator accepts contact that operation completes, therefore from operation be accomplished to set that instruction sends during life period lag behind, during this, be latch-release state, thereby cannot eliminate the problem that safety reduces.And operator needs to carry out to supvr the contact of the end of job during each end of job, it is loaded down with trivial details that operator can feel safe and manage.In addition, in the situation that the contact from operator to the gerentocratic end of job could not be passed on effectively, latch-release state continues, and produces safety and reduces this problems referred to above.
In addition, at latch-release, automatically become latch-release state constantly.Though start operation in operator plan, because the variation of the situations such as weather causes in situation that operation ends or in situation about postponing, latch-release state continues, and produces safety and reduces this problems referred to above.Have, during each aborting job, operator needs to carry out to supvr the contact of operation termination again, and it is loaded down with trivial details that operator can feel safe and manage.
On the other hand, in construction, when of short duration the stopping such as lunch break, construction machinery and equipment is stopped.The status recognition that the anti-joyride device of recording in patent documentation 1 or patent documentation 2 stops at construction machinery and equipment, power supply is removed password while being OFF, of short duration stopping, again start operation after finishing and while again starting construction machinery and equipment, need to again input password, it is loaded down with trivial details that operator can feel safe and manage.In the anti-joyride device of recording, after once carrying out, latch-release maintains latch-release state in aforesaid patent documentation 3, so operator the loaded down with trivial details of management that can not feel safe.But stop in the situation that of short duration, than predetermined length or because the variation of situation causes the operation after of short duration stopping, end, latch-release state continues, thereby produce safety, reduces this problems referred to above.

Above, input terminal 31, communicator 32, information acceptance division 41 in the control function of anti-theft controller 33, supvr's judging part 42, identifying information is checked portion 43, Password Input portion 44, cryptographic core is to portion 45, storage part 46, picture display part 47 and key signal judging part 48 have formed from outside input for removing the input information mechanism of information of illegal state of the action of hydraulic excavator, forbidding in the control function of anti-theft controller 33 removed time instrumentation portion 51, control part 52 is forbidden in mechanical action license, forbid that releasing time removing portion 53 has formed mechanical action control mechanism, this mechanical action control mechanism according to the information setting by input information Mechanism input for removing the forbidding the releasing time of illegal state of the action of hydraulic excavator, then only until forbid the releasing time through during in the illegal state of action of releasing hydraulic excavator, the starting of hydraulic excavator can be carried out, once and hydraulic excavator starting, maintain the releasing of illegal state.
Identifying information check portion 43 or cryptographic core to portion 45 formed by the cross-check information (password or identifying information) from outside input be stored in the mechanism of checking that cross-check information storage part 46 compares.
Forbidding removing time instrumentation portion 51 has formed and has forbidden removing time instrumentation mechanism, this forbids removing time instrumentation mechanism by checking cross-check information that mechanism compares when consistent, in being stored in storage part 46 and corresponding with cross-check information releasing effective time as forbidding that the releasing time sets, and instrumentation is forbidden the process of the time of removing.Mechanical action license forbids that control part 52 has formed mechanical action license and forbidden control mechanism, the license of this mechanical action forbid control mechanism forbidding the releasing time through before remove the illegal state of the action of hydraulic excavator, and forbidding that the releasing time is through again making the action of hydraulic excavator become illegal state later.
(action)
In present embodiment, as setting, forbid the method for the time of removing, the situation that the input terminal 31 that has the situation of being undertaken by gerentocratic vehicular telephone 5, situation that the vehicular telephone 6 by operator carries out and use anti-joyride device 3 to have carries out.
First, the action of setting the situation of forbidding the time of removing by gerentocratic vehicular telephone 5 is described.
To starting, use, stop the action of the process of hydraulic excavator, describe.
Before operation starts, before anti-joyride device 3 receives the short message from vehicular telephone 5, forbidding removing time instrumentation portion 51 does not set and forbids the releasing time, forbid that the releasing time is zero, mechanical action license forbids that control part 52, to engine controller 11 and car body controller 21 output mechanical action inhibit signals, maintains the illegal state of the action of hydraulic excavator 1.
Under this state, in production plan, change, operation postpones the zero hour or operation ends in the situation that, anti-joyride device 3 maintains the illegal state of the action of hydraulic excavator 1, thus, can not be subject to production plan change impact guarantee safety.In addition, operator does not need to carry out any operation, and what can not make that operator feels safe management guarantees safety loaded down with trivial detailsly.
When operation starts, supvr receives the contact from operator in advance, before operation starts, from vehicular telephone 5, to anti-joyride device 3, sends and records the short message that Enter Number corresponding with vehicular telephone 5.
When information acceptance division 41 receives short message by communicator 32, supvr's judging part 42 is judged to be gerentocratic vehicular telephone 5 but not to be the information for storing or upgrading, and the short message of the telephone number of vehicular telephone 5 and record is Entered Number and as identifying information, outputs to identifying information and check portion 43.Identifying information is checked portion 43 identifying information of input and the identifying information that is stored in storage part 46 is compared, if identifying information is consistent, corresponding releasing is outputed to effective time and forbids removing time instrumentation portion 51.Forbid removing time instrumentation portion 51 using this releasing effective time as forbidding that the releasing time sets, start countdown.Until forbid the releasing time through during in, forbid that the releasing time is non-vanishing, mechanical action license forbids that control part 52 is to engine controller 11 and car body controller 21 output mechanical action enabling signals, and the illegal state of the action of hydraulic excavator 1 is disengaged and can starts.
When illegal state is removed, operator is operated to ON position by key switch 12, carries out power supply supply, further key switch 12 is operated to starting position, driving engine 13 startings.In addition, if operator is operated to latch-release position by door lock fixed pole, door locked valve 23 action is communicated with first pilot, thereby can carry out the operation to anterior device etc.Once hydraulic excavator 1 starting, maintains the releasing of illegal state.In addition, in a series of actions of the starting of hydraulic excavator 1, operator does not need to carry out the input of identifying information etc.
Thus, what can not make that operator feels safe management starts hydraulic excavator 1 loaded down with trivial detailsly, and after this also can use constantly.Supvr can carry out safety management by remote operation.
On the other hand, although the illegal state of the action of hydraulic excavator 1 is disengaged as mentioned above, but cause operation in the situation that after this ending in the variation because of situations such as weather, forbid removing time instrumentation portion and 51 carry out countdown, when forbid the releasing time through and during vanishing, mechanical action license forbids that control part 52 is to engine controller 11 and car body controller 21 output mechanical action inhibit signals, and the action of hydraulic excavator 1 becomes illegal state.Be to carry out the short time (for example 60 minutes) of theft of hydraulic excavator 1 than thief's attempt the releasing effective time of setting as forbidding the releasing time.
That is, though outside production plan in the situation that, for example in predetermined operation in the situation that after this ending, the action of hydraulic excavator 1 also can automatically become illegal state, thus, can not be subject to production plan change impact guarantee safety.Therefore in addition, now, operator does not need to carry out to supvr the contact of operation termination, and what can not make that operator feels safe management guarantees safety loaded down with trivial detailsly.
During the end of job, operator is operated to OFF position by key switch 12 and supplies with and driving engine to stop power supply, and key signal judging part 48 is judged key OFF signal, forbids removing time instrumentation portion 51 input key OFF signals, and starting countdown, instrumentation is forbidden the process of the time of removing.When forbid the releasing time through and during vanishing, mechanical action license forbids that control part 52 is to engine controller 11 and car body controller 21 output mechanical action inhibit signals, the action of hydraulic excavator 1 becomes illegal state.
Now, even finish ahead of time in the situation that, also can make the action of hydraulic excavator 1 automatically become illegal state after the end of job than predetermined in operation, thus, can not be subject to production plan change impact guarantee safety.Therefore in addition, now, because operator does not need to carry out to supvr the contact that operation completes, what can not make that operator feels safe management guarantees safety loaded down with trivial detailsly.
In addition, during the end of job, the key OFF signal of picture display part 47 input key switches 12, and output shows the display of forbidding releasing time removing picture on read out instrument 35.If operator's attendant exclusion releasing time is removed picture, though forbid releasing time process during in, forbid that releasing time removing portion 53 is also to forbidding that removing time instrumentation portion 51 outputs will forbid removing the command signal of time zero setting.When forbidding removing time vanishing, mechanical action license forbids that control part 52 forbids control signal to engine controller 11 and car body controller 21 output mechanical actions, and the action of hydraulic excavator 1 becomes illegal state.
That is, if the attendant exclusion releasing time is removed picture after the end of job, the action of hydraulic excavator 1 directly becomes illegal state, thus, can not be subject to the impact ground of the change of production plan to guarantee more reliably safety.Therefore in addition, now, because operator does not need to carry out to supvr the contact that operation completes, what can not make that operator feels safe management guarantees safety loaded down with trivial detailsly.
Below the action after the hydraulic excavator 1 once having started is stopped, while again starting is described.
When of short duration the stopping such as lunch break, operator is operated to OFF position by key switch 12 and supplies with and driving engine to stop power supply, key signal judging part 48 is judged key OFF signal, forbid removing time instrumentation portion 51 this key of input OFF signals,, using releasing effective time as forbidding that the releasing time again sets and start countdown, instrumentation is forbidden the process of the time of removing.Until forbid the releasing time through during in, forbid that the releasing time is non-vanishing, mechanical action license forbids that control part 52, to engine controller 11 and car body controller 21 output mechanical action enabling signals, maintains the releasing of illegal state.
Now, if operator is operated to ON position by key switch 12, carry out power supply supply, if further key switch 12 is operated to starting position, driving engine 13 starts again.In addition, if operator is operated to latch-release position by door lock fixed pole, door locked valve 23 action is communicated with first pilot, again makes the operation of anterior device etc. carry out.In addition, in a series of actions of again starting of hydraulic excavator 1, operator does not need to carry out the input of cross-check information (password, identifying information).
What thus, can not make that operator feels safe management starts hydraulic excavator 1 loaded down with trivial detailsly again.
On the other hand, in the situation that of short duration, stop and end than predetermined length or because the variation of situation causes the operation after of short duration stopping, forbid removing time instrumentation portion and 51 carry out countdown, when forbid the releasing time through and during vanishing, mechanical action license forbids that control part 52 is to engine controller 11 and car body controller 21 output mechanical action inhibit signals, and the action of hydraulic excavator 1 becomes illegal state.
; even the in the situation that of outside production plan, for example in the situation that of short duration stopping than predetermined length or because the variation of situation causes the operation after of short duration stopping, end; the action of hydraulic excavator 1 also can automatically become illegal state; thus, can not be subject to the change of production plan to guarantee safety with affecting.In addition, now, because operator does not need to carry out to supvr the contact of operation termination, what therefore can not make that operator feels safe management guarantees safety loaded down with trivial detailsly.
Next, the action of the vehicular telephone 6 by operator being set to the situation of forbidding the time of removing describes.
In the situation that forbidding removing the time by gerentocratic vehicular telephone 5 settings as described above, supvr needs to accept in advance the contact from operator, but also has supvr and operator's the halfway situation of contact.
In this case, operator sends and records the short message Entering Number to anti-joyride device 3 from vehicular telephone 6 before operation starts.
When information acceptance division 41 receives short message by communicator 32, supvr's judging part 42 is judged and is not gerentocratic vehicular telephone 5, and the short message of the telephone number of vehicular telephone 6 and record is Entered Number and as identifying information, outputs to identifying information and check portion 43.Identifying information is checked portion 43 identifying information of input and the identifying information that is stored in storage part 46 is compared, because identifying information is consistent, therefore to forbidding removing 51 releasing effective times corresponding to output of instrumentation portion time.Forbid removing time instrumentation portion 51 using this releasing effective time as forbidding that the releasing time sets, start countdown.Until forbid releasing time process during in, forbid that the releasing time is non-vanishing, mechanical action license forbids that control part 52 is to engine controller 11 and car body controller 21 output mechanical action enabling signals, and the illegal state of the action of hydraulic excavator 1 is disengaged and can starts.
When illegal state is disengaged, if operator is operated to ON position by key switch 12, carry out power supply supply, if further key switch 12 is operated to starting position, driving engine 13 startings.In addition, if operator is operated to latch-release position by door lock fixed pole, door locked valve 23 action is communicated with first pilot, thereby can operate anterior device etc.That is, operator only need send short message from vehicular telephone 6, and hydraulic excavator 1 just can start.
Thus, even by gerentocratic vehicular telephone 5, what also can not make that operator feels safe management starts hydraulic excavator 1 loaded down with trivial detailsly.
In addition action, and is set and is forbidden that the situation of the time of removing is identical by gerentocratic vehicular telephone 5.
The action that the password of the input terminal 31 next, input being had from anti-joyride device 3 is set the situation of forbidding the time of removing describes.
When illegal state, operator is operated to ON position by key switch 12, and power supply is supplied with and started, and read out instrument 35 starts.Forbid removing time instrumentation portion 51 and judge and forbid that the releasing time is zero, do not set and forbid the releasing time, to picture display part 47 output judged results, picture display part 47 shows the Password Input picture that is used for inputting password on read out instrument 35.
Operator is by input terminal 31 input passwords.Herein, password is for example operator's the telephone number of vehicular telephone 6 and Entering Number of being distributed by vehicular telephone 6.
Thus, even the place of hydraulic excavator in obstructed vehicular telephone, operator also can start hydraulic excavator 1.
When the place of hydraulic excavator 1 in obstructed vehicular telephone, in the short message situation having sent from vehicular telephone 5 or vehicular telephone 6, the information acceptance division 41 of anti-joyride device 3 moves to reception information behind the place of logical vehicular telephone at hydraulic excavator 1.Identifying information check portion 43 by information appended post a letter date and time information with from the moment inside date and time information obtained of instrumentation portion 56, compare, because date and time information is different, thereby ignore the identifying information of transmission, and, even if identifying information is consistent, also not to forbidding removing 51 releasing effective times corresponding to output of instrumentation portion time.
Thus, even the place of hydraulic excavator in obstructed vehicular telephone, after also can preventing, the illegal state of the action of hydraulic excavator 1 is removed mistakenly.
In addition action, and is set and is forbidden that the situation of the time of removing is identical by vehicular telephone 5, vehicular telephone 6.
Finally, to by gerentocratic vehicular telephone 5 by cross-check information (telephone number of vehicular telephone, Enter Number) with remove the action being stored in storage part 46 and while upgrading effective time and describe.
Supvr records as storage or the vehicular telephone 5 of object or the telephone number of vehicular telephone 6 that upgrade, Enters Number, removes the short message of effective time to anti-joyride device 3 transmissions from vehicular telephone 5.
When information acceptance division 41 receives short message by communicator 32, supvr's judging part 42 is judged to be gerentocratic vehicular telephone 5 and to be the information for storing or upgrading, in the situation that do not store as the cross-check information of the vehicular telephone of object in storage part 46 and remove effective time, cross-check information and releasing are stored in storage part 46 effective time accordingly, and, in the situation that storing cross-check information and removing effective time, this cross-check information and releasing are upgraded effective time.
Thus, supvr can carry out safety management by remote operation.
Therefore, according to present embodiment, can not make operator feel loaded down with trivial details ground and be not subject to production plan change impact guarantee safety.And supvr can carry out safety management by remote operation.
