The specific embodiment
Below in conjunction with accompanying drawing, the present invention is carried out detailed implementation.
Number in the figure is: 1, basket body 2, electric cabinet 3, gig 4, pulling force sensor 5, micro controller system 6, circuit card 7, current sensor 8, obliquity sensor 9, Liquid Crystal Display (LCD) 10, keyboard 11, solid-state relay 12, electrical relay 13, annunciator.
Shown in Fig. 1, Fig. 2, Fig. 3 (Fig. 3-1 is to Fig. 3-3), a kind of aerial work basket autonomous cruise speed system comprises control module, acquisition module, human-computer interaction module and execution module.
Control module is made up of the circuit card 6 that micro controller system 5 is housed; main responsible the processing is provided by the signal that provides; after routine processes; become output signal and send execution module to; if basket body 1 tilts, then execution module requires to adjust basket body 1 heeling condition according to the leveling program, up to basket body 1 level; if basket body 1 overload or unbalance loading then execution module provide necessary protection operation according to the overload protection program, if gig 3 occur stall then execution module require to carry out overcurrent protection according to the overcurrent protection program.In addition, this module also is responsible for receiving keyboard instruction, work such as data display and state indication being provided for man-machine interaction.
Acquisition module is made up of pulling force sensor 4, current sensor 7, obliquity sensor 8.The acquisition of signal of basket body 1 heeling condition uses obliquity sensor 8 to realize that it can gather the angle of inclination of basket body 1 plane and level reference in real time, and is transferred to micro controller system 5.Gig 3 is respectively installed a pulling force sensor 4 with basket body 1 junction, and each gig 3 load size is provided in real time.Gig 3 corresponding current sensors 7, current sensor 7 is gathered the gig current signal in real time, for system judges whether each gig 3 the stall phenomenon occurs data are provided.
Human-computer interaction module is arranged on electric cabinet 2 case lids, is made up of keyboard 10, Liquid Crystal Display (LCD) 9.Described keyboard 10 comprises that upload control button, descending control button, automatic/hand change-over switch, level set button and reset key zero point.Operating personal can pass through keyboard 10 to micro controller system 5 transmit operations, setting and reset instruction, and application Liquid Crystal Display (LCD) 9 provides work such as data display and state indication for man-machine interaction.
Execution module is made up of solid-state relay 11, electrical relay 12, gig 3 and annunciator 13; the main instruction driving electrical relay 12 of being responsible for sending according to control module is finished the operation to each gig 3; and control annunciator 13 and send or close alarm, finally realize automatic leveling, overload protection and overcurrent protection.The micro controller system direct current signal is controlled the electrical relay 12 that exchanges indirectly by solid-state relay 11.
As shown in Figure 4, a kind of program circuit of aerial work basket autonomous cruise speed system is as follows: at first micro controller system 5 is carried out initialization, the continuous checking system running state of main circulating program afterwards, what at first detect is basket body 1 horizontality, and program can be discerned the three state of basket body 1 automatically: the low state in a right high left side; Horizontality; The high right low state in a left side.When procedure identification when hanging basket has been in the low state in a right high left side, signal feedback is handled to control system, stop the right low continuity in a high left side of hanging basket simultaneously earlier, and send signal and drive a left side (right side) gig 3 automatic compensation basket bodies and arrive horizontality.Equally, when procedure identification when hanging basket is in the high right low state in a left side, the identification of signal is adjusted program its state is handled.When procedure identification when hanging basket is in horizontality, send left and right sides gig 3 driving command simultaneously by control system, make and carry out the lifting operation under the hanging basket on even keel.Then detect basket body 1 condition of loading, if detect basket body 1 overload, program changes the overload protection subprogram over to, detects whether stall of gig 3 at last, if detect gig 3 overcurrents, program forwards the overcurrent protection subprogram to.
The strategy that overload protection adopts be with the load of single gig 3 as the basis for estimation that whether overloads, can realize basket body overload protection, can solve the situation of basket body unbalance loading again.The specific embodiment is to gather the pulling force signal of each gig 3 with pulling force sensor 4; handle through micro controller system 5; judge whether each gig 3 overloads; if overload then carry out following protection action: the gig numbering that on Liquid Crystal Display (LCD) 9, shows overload; give the alarm by siren horn 13, and forbid that other operations except that basket body 1 descends are removed up to the overload load.Because basket body 1 inertia is bigger; the startup of gig 3 and stop to cause basket body 1 vibration; this moment, the pulling force signal of pulling force sensor 4 collections can be suddenly big or suddenly small; if the protection load of overload protection setting is fixed value; then under zero boundary's situation; control system just might enter overload protection once and jump out overload protection once during 1 vibration of basket body, so not only influences operating efficiency, also can bring unnecessary trouble.Therefore; gig 3 is started and stop to be made as the dead band during this section when the design overload protection, micro controller system 5 is not handled the pulling force signal of gathering in the dead band, and will protect load to be arranged to a scope; on be limited to: rated load+20kg is limited to down: rated load-20kg.When load surpasses the last overload protection program of carrying out in limited time, have only load to be lower than down in limited time, just can jump out the overload protection program.
The strategy that overcurrent protection is adopted is as judging the whether foundation of stall of gig 3 with gig 3 current values.The gig rotation-clogging protection is to measure the gig current signal with current sensor 7; sending into micro controller system 5 handles; if the current value of measuring surpasses setting value; micro controller system 5 is presented at overcurrent gig numbering on the Liquid Crystal Display (LCD) 9; annunciator 13 gives the alarm, and forbids that gig 3 operations are until trouble removal.Gig 3 is in the moment that starts, and electric current can become big suddenly, surpasses the protection value of setting, and this situation does not belong to the electric current that stall causes and becomes big, can eliminate by software programming.
When autonomous cruise speed system breaks down, press " manual " button and switch to manual master mode operation hanging basket.This pattern has been cut off the power supply voltage of solid-state relay 11, execution module is not carried out control command, micro controller system 5, obliquity sensor 8 and Liquid Crystal Display (LCD) 9 be normal operation still, operating personal can obtain the heeling condition of basket body 1 by Liquid Crystal Display (LCD), and carries out corresponding manual leveling operation according to basket body 1 heeling condition that Liquid Crystal Display (LCD) 9 shows.
