Embodiment
Below by embodiment, and in conjunction with the accompanying drawings, the technical solution of the utility model is described in further detail.
Embodiment 1: the wire break alarm device of the frame winch of present embodiment, as shown in Figure 1, the frame of broken lines among Fig. 1 partly is the controller of wire break alarm device, and transducer 10 is as the signal generator of wire break alarm device, its acquired signal also sends to controller, by the controller processing signals.The 24V of wire break alarm device input power supply is provided by console controller, respectively as the working power of controller and transducer.Controller and transducer are two individual components, are installed in the different parts of frame strand body, and both link together by holding wire.
The controller of wire break alarm device is made up of software and hardware.It mainly receives handles 30 tunnel sensor signals, realizes the timely warning to every road signal, and finishes other functions such as selecting drum quantity, setting break alarm delay time, light or extinguish alarm lamp.
Hardware components: as shown in Figure 1, comprise single-chip microcomputer 1, single-chip microcomputer adopts the PIC18F452 signal processing chip in this example.First buffering driver 2, second buffering driver 3, latch 4 are extended device of data input with the output of single-chip microcomputer, and wherein first buffering driver and second buffering driver are made up of the 74HC244 chip, as the data inserter spare of single-chip microcomputer.Latch is made up of the 74HC373 chip, as the data logger spare of single-chip microcomputer.Optocoupler 5, selector switch 6, light-emitting diode 7 are peripheral components, and optocoupler is made up of the TLP281-4 chip, is photoelectric isolating device, can realize that the conversion of signals with transducer 10 is the treatable digital signal of single-chip microcomputer, can strengthen antijamming capability again.Light-emitting diode is an alarm lamp, and the drum position of broken string takes place in order to indication.Power transfer module 8 is as the power supply apparatus of single-chip microcomputer, with the 24V power source conversion of the outside input 5V working power for each components and parts needs.
The specific implementation process: 8 position datawires of single-chip microcomputer (PIC18F452) directly are connected with the data wire of first buffering driver (4 74HC244 chips), second buffering driver (5 74HC244 chips), latch (4 74HC373 chips).The chip selection signal of latch and first, second buffering driver can directly be realized by 13 bit function pins of single-chip microcomputer, also can finish by the function pin of single-chip microcomputer and a slice 38 decoders and the combination of a slice reverser, that this example adopts is the latter, can expand the function pin of single-chip microcomputer like this, prepare for expanding drum quantity later on or increasing other function.30 input pins of first buffering driver connect optocoupler 30 output pins of (8 TLP281-4 form), and 30 input pins of optocoupler connect the holding wire of No. 30 transducers respectively.First buffering driver, optocoupler and 30 tunnel sensor signal lines are formed the sensor signal importation of single-chip microcomputer.38 road input pins of second buffering driver (5 74HC244 core places) connect 38 way switch (wherein 4 tunnel is that drum selector switch, 4 tunnel is that break alarm delay switch, 30 tunnel is the effective or invalid switch of drum), form the switch of single-chip microcomputer and select stimulus part.30 road output pins of latch (4 74HC373 chips) connect 30 road alarm lamps (30 light-emitting diodes), form the break alarm lamp data output unit of single-chip microcomputer.Alarm signal directly outputs to console controller by a bit function pin of single-chip microcomputer.The 5V output pin of power transfer module (B2405S) is connected with ground pin with the 5V power pin of each element respectively with ground.
Transducer is used for responding to the rotation situation of drum as the signal generator of wire break alarm device, and output signal.Its specific implementation process is: as Fig. 2, shown in Figure 3, a gear 12 is housed on the drum 11, transducer 10 vertical edges over against gear 12.When drum rotated, driven gear rotated synchronously, and transducer maintains static, and when the tooth of gear passed through transducer, transducer had induction, the output high level; When the space was through transducer between gear teeth, transducer was non-inductive, output low level.For wheel disc also is so, and like this, during the drum normal rotation, transducer is output height interval level just, as the input signal of single-chip microcomputer.If break, then drum stops not change, and the output level perseverance of transducer is high level or low level.
Software specific implementation process: the program of wire break alarm device is kept in the single-chip microcomputer, the back program running that powers on, the data of scan round first buffering driver and second buffering driver.First buffering driver is preserved the signal data of transducer, and second buffering driver is preserved drum selector switch, break alarm delay switch, drum is effective or the status data of invalid switch.Program is handled the sensing data of first buffering driver according to the state information of second buffering driver.At first, program is read in corresponding drum sensing data according to the selected drum number of drum selector switch, and according to the effective or invalid on off state processing of drum effective sensor data, drum is not handled the invalid sensing data of inductive switch, in the selected delay time of broken string delay switch, if certain effective sensor data normally this drum normally move, the broken string situation does not take place, if the data exception of which effective sensor, promptly the sensing data perseverance of single-chip microcomputer input is 0 or 1 in delay time, show that then corresponding drum shuts down, the broken string phenomenon has taken place, and then the single-chip microcomputer output alarm signal is given console controller, and dateout is to latch simultaneously, light the alarm lamp of broken string drum correspondence, carry out next round scanning again.
The drum selector switch is used for selecting this frame to twist the drum sum that body is installed, like this, when controller applies to the frame strand body of different drum numbers is installed, need only select the drum number to get final product by switch, and need not change other hardware or software section, 4 switch combinations are selected, and can select 16 kinds of drum numbers at most, according to actual conditions, there are 6 dishes, 12 dishes, 18 dishes, 24 dishes, 5 kinds of drum numbers of 30 dishes to select at present.The break alarm delay switch is used for controlling the blanking time of breaking and reporting to the police to controller from drum, and 4 delay switchs can require to set for different delay times according to reality.When the fast turn-around of frame strand body, delay time can be turned down in the practical application, turn round when slow, delay time is heightened, software is regulated the frequency of reading in sensing data automatically according to the delay switch state, to guarantee the precision of break alarm.Effective or the invalid switch of each drum is corresponding one by one with the drum of frame strand body, if switch is invalid, even then this drum broken string is not reported to the police yet, to guarantee in the real work frame to be twisted the flexible control of each drum of body.
Drum breaks, and controller sends the break alarm signal, lights the alarm lamp of broken string drum correspondence, and disconnection fault is removed, and drum turns round again, and the controller break alarm signal that resets immediately extinguishes alarm lamp.
As Fig. 2, shown in Figure 3, the transducer 10 of present embodiment is installed in drum 11 places of frame strand body 14, and controller 15 is installed in an end of frame strand body.
