Detailed description of the invention
As shown in Figure 1 and Figure 2, the crane lift car safety distance based on ultrasonic transduter detects prior-warning device, comprises the distance detection device 1 be arranged in working bucket, the displaying alarm 2 be arranged in operator's compartment.
Described distance detection device 1 comprises the first power module, at least one ultrasonic testing module 3, each ultrasonic testing module 3 comprises a ultrasonic ranging probe 5, distance detecting unit 4, described ultrasonic ranging probe 5 connects distance detecting unit 4, described distance detecting unit 4 connects the first data processing module 6, and described data processing module 6 connects WIFI transmitter module 7.
Described displaying alarm 2 comprises second source module, the second data processing module 8, second data processing module 8 connects WIFI receiver module 9, LED display module 10, safety distance comparison module 11, annunciator 14 respectively.Second data processing module 8 connects LED display module.
Be provided with magnet 12 bottom described distance detection device 1, magnet 12 and working bucket bucket form magnetic adsorption type structure between 13, are respectively equipped with ultrasonic ranging probe 5 at working bucket bucket along 13 forward and backward two ends.
Described LED display module 10 comprises LED display, LED drive circuit, and described LED display connects LED drive circuit.
Described annunciator 14 is combined aural and visual alarm, and combined aural and visual alarm comprises alarm lamp, loud speaker.
Described first data processing module 6, second data processing module 8 is one-chip computer module.
Described safety distance comparison module 11 comprises the amplification and rectification circuit, digital comparator, the starting or stopping control circuit that connect successively,
Described digital comparator is used for detected value and setting value to compare;
Described starting or stopping control circuit is for controlling the start and stop of annunciator 14.
Described first power module, second source module are 12V chargeable lithium cell group.
Described ultrasonic testing module 3 is two, is distributed in working bucket bucket along 13 forward and backward two ends.
WIFI signal transmission path is had between distance detection device 1 and displaying alarm 2.Two ultrasonic testing modules 3 in distance detection device 1 can the distance of simultaneously collecting work bucket and the many air wires in side, front and back, after first data processing module 6 reads range data, it is wirelessly transmitted to by WIFI transmitter module 7 in the WIFI receiver module 9 in displaying alarm 2.The second data processing module 8 in displaying alarm 2 reads after data process, only retain minimum distance value, then this minimum value is sent in LED display and shows, also to be passed in safety distance comparison module 11 simultaneously thus to determine whether report to the police.
