Control circuit of the present invention comprises central controller 20, and this central controller 20 adopts programmable logic controller (PLC) (PLC), is convenient to the purpose that the user freely programmes to realize robotization control.
Topworks of the present invention comprises air-pressure duct, the cylinder 13 that communicates with air-pressure duct and the solenoid valve that is series at air-pressure duct, and solenoid valve and central controller 20 are electrically connected.Because air-pressure duct communicates with cylinder 13, central controller 20 is connected with solenoid valve, this solenoid valve is series at air-pressure duct, change air-pressure duct for the atmospheric pressure of cylinder 13 when central controller changes the state of solenoid valve, realize that the mobile terminal of cylinder 13 forces in or do not force in horn button.
Test loop of the present invention comprises A.C. contactor 18, shunt 21, horn button 12 and the loudspeaker load 17 of series connection.The electric current of A.C. contactor 18 output is back to A.C. contactor 18 after through shunt 21, horn button 12 and loudspeaker load 17, forms a loop, and when A.C. contactor 18 pairs of these test loops provided electric energy, this test loop had current signal.
Testing circuit of the present invention comprises reometer 19, two input ends 191,192 of reometer 19 are parallel to first, second input port 201,202 that shunt 21, two output terminals 193,194 are electrically connected at central controller 20, as one of input of central controller 20, the clocking capability by central controller 20 judges whether the contact of horn button 12 occurs opening circuit with reometer 19.Testing circuit comprises the first relay 15, the coil 151 of the first relay 15 is parallel to loudspeaker load 17, one contact 152 of the first relay 15 is electrically connected at the 3rd input port 203 that test loop, another contact 153 are electrically connected at central controller 20, as one of input of central controller 20, the clocking capability by central controller 20 judges whether the contact of horn button 12 normal open that lost efficacy occurs with the first relay 15.
Control circuit of the present invention comprises city's electric knife switch 14 and the second relay 16, and city's electric knife switch 14 is linked in sequence and is back to city's electric knife switch 14 after the coil 181 of two normally closed contacts 162,163, A.C. contactor 18 of the second relay 16; First, second output port 204,205 of central controller 20 is electrically connected at coil 161 two ends of the second relay 16.As one of output of central controller 20, if there is inefficacy, this second relay 16 test loop of will breaking stops bench run with the second relay 16
Loudspeaker load 17 of the present invention is light-emitting component, uses the light-emitting component of equivalent power such as bulb to replace loudspeaker as circuit load, has solved noise problem, more environmental protection.
Pilot system of the present invention comprises alarm unit, and this alarm unit and central controller 20 are electrically connected.Point out user by alarm unit when central controller 20 detects when horn button 12 lost efficacy, in time process this situation to facilitate the user.
principle of work of the present invention is: when city's electric knife switch 14 is closed, electric current is by two normally closed contacts 162 of the second relay 16, 181 1 of the coils of 163 inflow A.C. contactors 18, city's electric knife switch 14 negative poles are got back in coil 181 other ends by A.C. contactor 18, when system switches on, A.C. contactor 18 coils 181 form the loop and make and become the normal open point the normal battle of A.C. contactor 18, electric current arrives shunt 21 by A.C. contactor 18, the input end 191 of reometer 19, 192 are parallel to shunt 21 two ends, electric current from shunt 21 out after, to horn button 12 contacts, this moment, circuit was divided into two, article one, out connect bulb from the contact and get back to A.C. contactor 18 negative poles, article one, out connect the coil 151 of the first relay 15 from the contact.When system started, cylinder 13 began action, and horn button 12 is pressed by cylinder 13, and the whole system row becomes the loop, bulb is shinny, and when cylinder 13 reclaimed, horn button 12 rebounded, circuit disconnects, and bulb extinguishes, and can come the setpoint frequency cycle according to different standard-requireds.
Wherein two output ports 204,205 of central controller 20 are received solenoid valve, and solenoid valve connects cylinder 13 by air-pressure duct, and when central controller 20 obtained programmed instruction output, solenoid valve got electric, thereby makes cylinder 13 to move back and forth.The input end 191,192 of reometer 19 is received the shunt 21 in loop; and output terminal 193,194 is received first, second input port 201,202 of central controller 20; the signal of hi-lo signal alarm can be input to central controller 20, realizes the Real Time Monitoring of electric current and reports to the police and shut down.The normally closed contact of the second relay 16 is to join with city's electric knife switch, A.C. contactor, coil is received the delivery outlet of central controller, effect is to disconnect whole loop, when central controller is judged the horn button inefficacy, can make the output port output that connects the second relay, thereby make the coil electricity stroke loop of the second relay, the normally closed contact of the second relay disconnects, thereby makes whole loop disconnect.
This test loop, its voltage 13 ± 1V, electric current 6A, load 35 ± 10N, logical 1s, disconnected 3-4s uses software RS Logix500 that central controller is programmed, the functions such as the input by the first relay and timer, the power down function after realizing the differentiation of two kinds of failure modes and failure mode occurring.
The present invention adopts the test loop, is equipped with testing circuit and control circuit, can the simple and easy control compression frequency cycle, and in time find failure state, guarantee that test figure is accurate.
In addition, this pilot system can read the current value in the test loop intuitively, and its peak value is carried out record.
Above content is in conjunction with concrete preferred implementation further description made for the present invention, can not assert that concrete enforcement of the present invention is confined to these explanations.For the general technical staff of the technical field of the invention, without departing from the inventive concept of the premise, can also make some simple deduction or replace, all should be considered as belonging to protection scope of the present invention.
