The specific embodiment
To combine the accompanying drawing in the embodiment of the invention below, the technical scheme in the embodiment of the invention is carried out clear, intactly description, obviously, described embodiment only is the present invention's part embodiment, rather than whole embodiment.Based on the embodiment among the present invention, those of ordinary skills are not making the every other embodiment that is obtained under the creative work prerequisite, all belong to the scope of the present invention's protection.
Embodiment one
Electric-control motor (hereinafter to be referred as driving engine) generally all is housed on the movable crane, and driving engine is controlled by Engine ECU (electronic control unit).Engine ECU is through various sensor signals of gathering driving engine or the mode of operation that bus data is controlled driving engine, like the startup of control driving engine, flame-out, output speed, output torque etc.And the GPS terminal of installing on the hoisting crane not only can send to GPS control center with parameter, the engine breakdown information of locating information, speed information, driving engine operation, but also can receive the remote commands such as lock car that GPS control center sends through antenna.
Fig. 2 is the electrical schematic diagram of the embodiment of the invention one, comprising: storage battery 201, power-on switch 202, insurance 203, GPS terminal 204, Engine ECU 205.Wherein, storage battery 201 is connected to GPS terminal 204, for the 204 long-term power supplies of GPS terminal make it and can position.Storage battery 201 is connected with power-on switch 202, insurance 203, Engine ECU 205, is Engine ECU 205 power supplies.GPS terminal 204 is parallel on the power supply of Engine ECU 205, is used for waking GPS terminal 204 up.Simultaneously, GPS remote terminal 204 also couples together through the bus of being made up of two CAN buses 206 with Engine ECU 205, to carry out data exchange.
Suppose to have specified the GPS terminal to bind with one when Engine ECU is initial, be the two and set up man-to-man relation, for example in Engine ECU, having prestored and having specified the cooresponding password in GPS terminal is second encrypted message.Wherein saidly comprise a variety of situation when initial, as can being when dispatching from the factory, or when consigning to buyer or tenantry, also or when buyer or tenantry restart performance of the contract, or the like.So; In the normal use afterwards; During each start the engine, perhaps at set intervals, perhaps at the appointed time or the like; Can judge that the GPS terminal of originally being bound is whether said appointment GPS terminal is also made punishment by user's dismounting accordingly, prevents that the user from removing the purpose at GPS terminal privately thereby reach through the method in the present embodiment.Referring to shown in Figure 3, the present embodiment method may further comprise the steps:
S301: obtain first encrypted message that send at the Current GPS terminal.Be that the Current GPS terminal is initiatively sent or answered the requirement of Engine ECU and send an encrypted message to Engine ECU to Engine ECU, i.e. first encrypted message, said first encrypted message is used to verify the legitimacy at Current GPS terminal.
S302: do not match if get access to second encrypted message that said first encrypted message or said first encrypted message that gets access to and Engine ECU prestore, then get into step S303.Wherein said second encrypted message is corresponding with appointment GPS terminal, and said appointment GPS terminal is the GPS terminal of binding mutually with said Engine ECU.
First encrypted message that Engine ECU gets access to has three kinds of possible situation:
The first, first encrypted message is empty, and promptly Engine ECU does not get access to first encrypted message, shows that then the user has removed the GPS terminal privately.The second, but first encrypted message for empty do not match with second encrypted message, does not show that then the user removes and changed the GPS terminal privately, i.e. non-GPS terminal of before having been bound, current GPS terminal is so cause two passwords inconsistent.Three, first password be not empty and with second encrypted message coupling, show that then the GPS terminal is legal, do not removed privately or replace by the user.For first, second kind situation is the situation that the user has removed the GPS terminal privately, will get into step S303 with reply.And be normal circumstances for the third situation, then Engine ECU will let the driving engine normal operation, like normal startup or continue normal operation etc.
S303: generate and storage lock car instruction in said Engine ECU, to lock the car operation according to said lock car instruction.Because the user removes or even changed the GPS terminal privately,, then can generate and storage lock car instruction in said Engine ECU so as punishment.As long as obtained the instruction of lock car, the purpose of present embodiment method has also just reached so.As for according to said lock car instruction when lock car and through mode how or says that what locks the car strategy through locks car; Then multiple choices can be arranged: for example can be the current car of just locking, promptly this limiting engine starts or reduces the output torque of driving engine; Also can lock car again, when promptly user next time is desired start the engine and limiting engine starts or reduce the output torque of driving engine in next time.
Through the method for present embodiment, if the user has removed the GPS terminal of original binding privately, Engine ECU just can not receive password or receive wrong password so, thereby can produce the instruction of lock car, and the user is formed punishment.It is thus clear that the present embodiment method can prevent that the GPS terminal is removed by actv..
In addition; If the user does not repay mortgage loan; Control center also can send special instruction to the GPS terminal so; Make the GPS terminal send the first wrong password, thereby also can cause generating the instruction of lock car, so also just realized crane engine is carried out the function of Telelock car control to driving engine.
Embodiment two

S403: judge whether and the GPS terminal binding.Be Engine ECU judge self whether with a GPS terminal binding.For example judge i.e. second password of password that self whether has preset GPS terminal coupling usefulness,, explain that then Engine ECU binds with a GPS terminal if preset.
Notice that begin from S403, this flow process will be divided into two branches, one is to be the routine judgement branch of beginning with S404, is the core of this flow process, and another then is to be the initialization branch of beginning with S411.
If bind, then continue to get into S404 downwards, promptly get into the conventional branch of judging, so that the legitimacy at Current GPS terminal is judged.If do not bind, then jump to S411, promptly get into initialization branch, do some initialized work earlier.
S404: judge whether to remove GPS lock car function.If comprised the instruction of removing GPS lock car function in the said messaging parameter, then got into S410; If do not comprise, then continue to get into S405 downwards.The instruction of said releasing GPS lock car function generally is that send according to the Long-distance Control of control center at the GPS terminal.
S405: judge whether to have the instruction of lock car.Promptly judge and whether had the instruction of lock car in the Engine ECU.If have, then show and lock car, get into step 409; If do not have, then get into S406.
S406: judge whether the password that sends at the Current GPS terminal is correct.This step is a core procedure, promptly judge first encrypted message that Current GPS terminal that previous (S402) gets access to sends whether with Engine ECU in second encrypted message that presets be complementary.If mal does not match for empty (being the current GPS of installation terminal) or with second encrypted message like first encrypted message, then get into S408.If correct, then get into S407.
S407: driving engine normal operation.Be that Engine ECU makes the driving engine normal operation, this flow process finishes.
S408: generate also in the instruction of Engine ECU storage lock car, with as punishment to the user, this flow process end.Because the first encrypted message mal is removed or changes so conclude the GPS terminal, the instruction of storage lock car is so that lock car to driving engine when carrying out this flow process next time.Need to prove that as long as obtained the instruction of lock car, the basic purpose of present embodiment flow process has also just reached so.As for according to said lock car instruction when lock car and through mode how or says that what locks the car strategy through locks car, then can have multiple choices.In the present embodiment, preferred, from consideration, in this flow process, do not lock the car operation immediately to user security, carry out but wait until next time, carry out again when implementing S405 after the promptly next driving engine energising.
S409: lock the car operation according to the lock car strategy that presets.For example limiting engine starts or reduces the output torque of driving engine.This flow process finishes.
S410: unbind.I.e. second clearing password of the passwords at Engine ECU GPS terminal that self is preset for example is with unbind.Get into S407 then.
S411: judge whether to install the GPS terminal.Can judge the current GPS terminal of whether having installed according to the accessed said messaging parameter of S402.If do not install, then can jump directly to S407; If install, then continue to get into S412 downwards.This three step of S411 to S413 belongs to initialization branch, is used for when initial, Engine ECU being carried out the GPS terminal binding.Different with conventional branch, initialization branch is general only to carry out once or only carries out where necessary, for example when dispatching from the factory or when paying etc.
S412: the request that judges whether to bind GPS.If comprised the bind request at GPS terminal in the said messaging parameter, then continue to get into S413 downwards; Otherwise skip to S407.
S413: read and store the Current GPS terminal password is installed.That is, regard first encrypted message that Current GPS is sent as the installation password, and be stored in the Engine ECU,, be provided with the usefulness that the GPS terminal legality is judged in the back with as second encrypted message.Get into S407 then.
