Fig. 1 has the protection pressing plate control system system diagram of contact output for the utility model embodiment;
Fig. 2 protects pressure plate structure figure for the utility model embodiment;
Fig. 3 protects pressing plate exit status schematic diagram for the utility model embodiment;
Fig. 4 drops into view for the utility model embodiment protects pressing plate.
Reference numeral: 1 protection pressing plate body, 2 pressing plate braces, 3 control boards, 4 magnet steel, 5 transducers, 6 alarming devices, 7, communication module
Embodiment
Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described in detail.
As shown in Figure 1, have the protection pressing plate control system of contact output, comprise monitoring host computer, signal repeater and protection pressing plate.Signal repeater gathers contact signal, and is connected with monitoring host computer by the communication modes of RS485.Monitoring host computer compares identification according to the operation masterplate of inside to the state of protection pressing plate, and analyzes the result, compare correctly then normally, finds that mistake will be sent out to misrepresent deliberately the police, reaches and improves accuracy and operating efficiency, the purpose of reduction rate of failure and operating cost.
The designed protection pressing plate of native system is contact-carrying output, and when the state of protection pressing plate changed, the contact output variable is corresponding changing also.System is by judging the state of protection pressing plate to the contact output variable.
As shown in Figure 2; the protection pressing plate of present embodiment comprises protection pressing plate body 1, pressing plate brace 2, control board 3, magnet steel 4 and sensing air to air 5; described control board 3 is installed on the protection pressing plate body 1; described magnet steel 4 is installed on the pressing plate brace 2; transducer 5 is installed on the control board 3, and transducer 5 is corresponding with the movement position of magnet steel 4.Also be provided with the alarming device 6 and the communication module 7 that are used to indicate protection pressing plate state on control board 3, communication module connects signal repeater, and communication module can be wireless communication module, also can be wire communication module.The transducer 5 that present embodiment adopts is Hall element, and the alarming device 6 of employing is two indicator lights, and one of them is green indicating lamp, and another is red led.
Signal repeater of the present utility model and protection pressing plate can be several, and present embodiment adopts 2 signal repeaters, 4 protection pressing plates.
Move back in the process in the throwing of protection pressing plate, correct guiding indication can reduce error rate greatly.The order masterplate moves back by monitoring host computer good throwing prepared in advance in system; remove to control the indicator light of protecting on the pressing plate 6 by control program; 1. after number protection pressing plate drops into as: masterplate setting; should be to continue to drop into 3. number protection pressing plate; so behind 1. number end of operation; 1. " to finish " indicator light bright for number protection pressing plate, and 3. " pre-operation " indicator light of number protection pressing plate flicker simultaneously represents that next step should throw 3. number protection pressing plate.
As shown in Figure 3; unclamp the fixture on the protection pressing plate body; open pressing plate brace 2; when this moment, the whole protecting pressing plate was in exit status; magnet steel 4 separates with Hall element 5; Hall element 5 inductions are less than magnet steel 4, and control board 3 is just exported the normally opened contact signal like this, and corresponding protection pressing plate is in exit status.
As shown in Figure 4; pressing plate brace 2 closes; the fixture of fastening protection pressing plate body; when this moment, the whole protecting pressing plate was in the input state; magnet steel 4 overlaps with Hall element 5; Hall element 5 is sensed magnet steel 4, and control board 3 is just exported the normally-closed contact signal like this, and corresponding protection pressing plate is in the input state.
By the way, just can correspond to often opening and normally-closed contact of control board 3 outputs to input and the exit status of protection pressing plate, be transferred to monitoring host computer by signal repeater again, monitoring host computer according to pressing plate throwing move back masterplate and compare, judge whether state correct
Explanation is at last, above preferred embodiment is only unrestricted in order to the technical solution of the utility model to be described, although the utility model is described in detail by above preferred embodiment, but those skilled in the art are to be understood that, can make various changes to it in the form and details, and not depart from the utility model claims institute restricted portion.
