The specific embodiment
For further understanding summary of the invention of the present utility model, characteristics and effect, enumerate following examples now, and conjunction with figs. describes in detail of the present utility model as follows:
As Fig. 1, shown in Figure 2, the pivoted frame angle controller of pressure-vaccum ash equipment of the present utility model, include the PLC control module, simultaneously, the pivoted frame end plate 4 of pressure-vaccum ash equipment is provided with a plurality of and each station 6 corresponding induction iron block 3, the induction iron block 3 that the support 5 of pressure-vaccum ash equipment is provided with on the pivoted frame end plate 4 with pressure-vaccum ash equipment is corresponding near switch bracket 2, the described induction type that is provided with pivoted frame end plate 4 anglecs of rotation that are used to control pressure-vaccum ash equipment near switch bracket 2 is near switch 1, and described induction type connects the PLC control module near switch 1 by shielded cable.
As shown in Figure 3, each responds to the periphery that iron block 3 and the position of station 6 are arranged on the pivoted frame end plate 4 of pressure-vaccum ash equipment one to one.
As shown in Figure 1, described PLC control module includes PS307 module, CPU315-2DP, SM321 module and SM322 module, described induction type is near the input of switch 1 by the SM321 module in the lead connection PLC control module, and the output signal of the CPU315-2DP in the described PLC control module connects the pivoted frame transmission system by the PROFIBUS-DP bus.
As shown in Figure 4, when the CPU315-2DP in the PLC control module handles framing signal, need remove the dither signal that material loading, parking, startup etc. cause by time filtering, otherwise cause the pivoted frame misoperation, make device fails, and this signal that puts in place is necessary near the detected signal rising edge of switch.Therefore, the signal that puts in place of signal jitter is removed in CPU315-2DP filtering service time in the described PLC control module, is to adopt near the detected rising edge signal of switch as the useful signal source.
The course of work of the pivoted frame angle controller of pressure-vaccum ash equipment of the present utility model is: when the work of pressure-vaccum ash equipment, the pivoted frame end plate 4 of pressure-vaccum ash equipment begins to rotate from zero position, structure as shown in Figure 2, pivoted frame end plate 4 rotates counterclockwise, the induction iron block 3 that is fixed on the end plate 4 also begins to move, when induction iron block 3 arrives induction types near the induction region of switch 1, induction type near switch 1 immediately the SM321 module in the PLC control module send the signal that puts in place, after this signal is handled through the PLC control program, by the PROFIBUS-DP bus control command is sent, pivoted frame is stopped operating, be parked in accurately on the station 6.After the operation of this station 6 was finished, pivoted frame continued rotation, and next induction iron block 3 arrives the induction region of induction type near switch 1, continues as above process operation.
The control method of CPU315-2DP in the described PLC control module as shown in Figure 4, pressure-vaccum ash Device Host detects whether induction type is the rising edge signal near the signal that switch sends when rotating, if not the rising edge signal, main frame is rotated further, if rising edge signal, main control system stops operating, finish the operation of this station after, return and begin to rerun.
