Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is described in further detail.
The technical solution used in the present invention is as shown in Figure 1: a kind of excavator control device based on authority mechanism, comprises motor ECM1, ignition key switch 2, pilot control switch 3, starter relay 4, main pump power electromagnet valve 5, master controller 6, bus control panels 7, electronic monitor 8, GPS controller 9, mobile communication platform 10, GPS terminal parametric controller 11 and cell-phone customer terminal 12.
It is interconnected that motor ECM1 and master controller 6 pass through CAN, and " C " end of ignition key switch 2 is electrically connected on one of them " DI " port of master controller 6; The constant open contact of pilot control switch 3 is electrically connected on master controller 6 another one " DI " port; One of them " DO " port of the pull-in winding electrical connection main control of starter relay 4; " PWM " port of master controller is electrically connected on main pump power electromagnet valve 5; An other road CAN communication interface of master controller 6 passes through bus bar with bus control panels 7, electronic monitor 8, GPS controller 9 respectively simultaneously; GPS controller 9 is connected to mobile communication platform 10 by the GSM antenna carried with wireless electromagnetic communication formation; Mobile communication platform by Ethernet and GPS terminal parametric controller 11, simultaneously mobile communication platform 10 by wireless telecommunications form and cell-phone customer terminal 12 interconnected.
Further, because Windows operating system is most popular operating system, so GPS terminal parametric controller 11 is the network control platform based on Windows operating system.
Further, because smart mobile phone uses Android operation system at present, i Phone uses ios operating system, so cell-phone customer terminal 12 is the cell-phone customer terminals based on Android operation system or ios operating system.
Electronic monitor 8 and bus control panels 7 can adopt Split type structure, also bus control panels can be inherited with on electronic monitor 8, also the bus control panels 7 in system can be removed when electronic monitor 8 is touch-screen, replace by key control with touch control.
As shown in Figure 3, the control method of the described excavator control device based on authority mechanism comprises the following steps:
Step S1, after the ignition key switch 2 being positioned at driver's cabin is pushed the shelves that power on " ON " position by operating personnel, now system electrification, electronic monitor 8 is lighted, and electronic monitor 8 is at main interface particular display area display input control of authority password; If first time uses machine, password is defaulted as nothing, and the password trigger key of setting on bus control panels 7 can be used to enter Password Input state, and then directly press acknowledgement key, system will unlock; If not first time uses machine, enter step S2;
Step S2, operating personnel's input is used for engine start, operation and hydraulic system power control of authority password;
Step S3, judge operating personnel's input be used for engine start, operation and hydraulic system power control of authority password whether correct, enter step S4 after Password Input is correct, Password Input mistake repeats step S2;
Step S4, after the password for engine start, operation and hydraulic system power control of authority of operating personnel's input is correct, master controller 6 detects the state of pilot control switch 3; If pilot control switch 3 is in open mode, enter step S5; If pilot control switch 3 is in lockup state, enter step S6;
Step S5, master controller will forbid the control coil driving starter relay 4, thus stop starting;
Step S6, master controller will drive the control coil of starter relay 4, thus connects start loop, allows motor to run; Master controller 6 couples of motor ECM1 carry out normal rotating speed control simultaneously, and also will be unlocked the control of main pump power electromagnet valve 5, excavator can normally run.
As shown in Figure 2, further, the step that in described step S2, password obtains is:
Step S2-1, electronic monitor 8 can point out input cryptographic session frame, there will be six random codes above Password Input is capable simultaneously;
Step S2-2, random code is issued the customer service number of the mobile communication platform 10 pre-set by operating personnel by editing short message " CP+UP+ random code " with cell-phone customer terminal 12;
Step S2-3, mobile communication platform 10 judges to need to arrange user right password according to content, this information is transmitted to GPS terminal parametric controller 11 simultaneously;
Step S2-4, GPS terminal parametric controller 11 utilizes program computation to go out to revise the password of authority according to random code automatically;
Step S2-5, then web-privilege password Web is sent to cell-phone customer terminal 12 by mobile communication platform 10;
Step S2-6, operating personnel input this web-privilege password Web on bus control panels 7;
Step S2-7, access entitlements change of secret code menu, carries out change of secret code, select wherein one group be arranged to password;
Step S2-8, whether acceptance setting, if accepting to arrange directly selects acknowledgement key, can show below password is capable and initialize and confirm, select to confirm that rear pressing confirms button, this group password arranges successfully, and other need the cipher code set arranged with above principle, then enter step S2-9, if do not accept when group is arranged, can select to initialize, this group password is cleared, and repeats step S2-7;
Step S2-9, after password is provided with, that selects to be positioned at this menu bottom completes item, and system is automatically by the specific region of password backup to electronic monitor 8, the password of this specific region can be inquired about after needing dynamic password to input, and this authority only main frame production firm is held; The encrypted message of storage is sent to GPS controller 9 by bus by electronic monitor 8 simultaneously, information is sent to mobile communication platform 10 by the GSM antenna of oneself with electromagnetic signal form by GPS controller 9 again, and encrypted message is issued GPS terminal parametric controller 11 and cell-phone customer terminal 12 to realize password backup by mobile communication platform 10 more respectively;
Step S2-10, password is arranged successfully.
Further, the method of change of secret code in described step S2-7 is: behind described electronic monitor (8) display control of authority password amendment interface, operating personnel can arrange at most 6 groups of passwords according to self-demand, often organize password and support at most 6, the numeral of every password is 0-9 or sky, operating personnel by the left and right options button on bus control panels 7, can switch the password position that will arrange, change Digital size by upper and lower key.
Further, in described step 2-2, owner's search access right that owner is authorized by main engine plants utilizes network on cell-phone customer terminal 12, according to the access entitlements of different operating personnel, can inquire about the job information that GPS terminal parametric controller 11 adds up different personnel.
Because during every task, operating personnel input different web-privilege password Webs and start a machine, master controller 6 all can add up content of operation and the duration of these operating personnel, then statistical content is sent to GPS controller 9 by CAN by master controller 6, information is sent to mobile communication platform 10 by GSM antenna with the form of electromagnetic signal by GPS controller 9, and information is forwarded to GPS terminal parametric controller 11 by mobile communication platform 10.Main engine plants authorize owner use search access right certain on GPS terminal parametric controller 11, and owner utilizes network just can inquire about the job information that GPS terminal parametric controller 11 adds up different personnel, so that it is to the operation management of operating personnel and machine.
