Embodiment
The utility model proposes a kind of Relay logic control system that exchanges, it forms as shown in Figure 1, comprising: system synthesis Xian Kong center 1, switch control logic circuit 2, state indication unit 3, long-distance transmissions cable 4, distal portion system and equipment 5, A.C. contactor 6 and demonstration DC power supply 7.
System synthesis Xian Kong center 1 connects distal portion system and equipment 5 by long-distance transmissions cable 4.
On system synthesis Xian Kong center 1, be provided with manipulation table top; Switch control logic circuit 2 and state indication unit 3 are arranged on the manipulation table top at system synthesis Xian Kong center 1.The signal that operator on duty sends according to the state indication unit 3 in each subsystem, is completed distal portion System Computer equipment is powered up to the control operation such as power-off, Emission Lasers by switch control logic circuit 2.
A.C. contactor 6 and demonstration DC power supply 7 are arranged on the inside of distal portion system and equipment 5.
A.C. contactor 6 is for disconnection and the closure of finishing equipment power supply.This A.C. contactor 6 comprises main contacts K, auxiliary contact K1 and coil L; The main contacts K of A.C. contactor 6 is connected with the major loop of the power supplied locally power supply of distal portion system and equipment 5, and the auxiliary contact K1 of A.C. contactor 6 is connected with switch control logic circuit 2 by long-distance transmissions cable 4 with coil L.Coordinate by this A.C. contactor 6 and switch control logic circuit 2 action that adds electric switch and cut-off switch, can realize connection and the disjunction of the alternating current circuit of system synthesis Xian Kong center each distal portion system of 1 far distance controlled and equipment 5.The electric current that flows through auxiliary contact K1 and coil L while work due to A.C. contactor 6 is very little, and long-distance transmissions cable 4 can generate heat less like this, therefore can ensure that long distance line loss is little, thereby can improve the fail safe of long-distance transmissions.
Show that the power supply of DC power supply 7 is input as the power supply output of A.C. contactor 6, show that DC power supply that DC power supply 7 exports is connected with the state indication unit 3 being arranged on the manipulation table top at system synthesis Xian Kong center 1 by long-distance transmissions cable 4.Like this, whether distal portion system and equipment 5 normally work, and just can reflect by state indication unit 3 at system synthesis Xian Kong center 1.
Above-mentioned Fig. 1 only illustrates Liao Yi road control principle, actual interchange Relay logic control system is that multidiameter delay is worked simultaneously, concentrate on different distal portion system and the equipment 5 of many groups switch control on the operation bench at system synthesis Xian Kong center 1, but operation principle is consistent, is not described in detail here.
The theory of constitution figure of above-mentioned switch control logic circuit 2 as shown in Figure 2, comprising: cut-off switch SB1, power up switch S B2, control common port, power up control end, power-off control end.
Controlling common port is connected between the zero line (220VN) and the coil L of A.C. contactor 6 of external public power at system synthesis Xian Kong center 1; Powering up control end is connected to the coil L of A.C. contactor 6 and powers up between switch S B2; Power up switch S B2 in parallel with the auxiliary contact K1 of A.C. contactor 6; Power-off control end is connected to and powers up between switch S B2 and cut-off switch SB1, the live wire (220VL) of the external public power at cut-off switch SB1 system synthesis Xian Kong center 1.The main contacts K of A.C. contactor is arranged between externally fed end and the input of distal portion system and equipment.
Above-mentioned cut-off switch SB1 is normally closed without lock-switch, powers up switch S B2 for often opening without lock-switch.
Press and power up switch S B2, coil L energising in A.C. contactor 6 in distal portion system and equipment 5, main contacts K closure in A.C. contactor 6, connect the power supply of distal portion system and equipment 5 and complete startup work, simultaneously in the A.C. contactor 6 in parallel with powering up switch S B2, often open auxiliary contact K1 closure, the coil L in adhesive A.C. contactor 6 switches on through two paths; Unclamp when pressing the hand that powers up switch S B2, powering up switch S B2 automatically resets as normally open, coil L in A.C. contactor 6 still can continue to keep energising by the adhesive of auxiliary contact K1, thereby ensure the adhesive of main contacts K, distal portion system and equipment 5 keep normal power-up work, so just realize auxiliary contact K1 and powered up the normally open contact parallel connection of switch S B2, thereby can ensure that coil L keeps the auto-lock function of energising for a long time.As can be seen here, the Logic Circuit Design between the auxiliary contact of the normally opened contact that powers up switch S B2, cut-off switch SB1 normally-closed contact and the A.C. contactor 6 by switch control logic circuit 2 has ensured auto-lock function of the present utility model.
Press cut-off switch SB1 button, current supply circuit disconnects, A.C. contactor 6 power-off discharge, it is often opened main contacts K power supply circuit is disconnected, in the time unclamping cut-off switch SB1 button, though cut-off switch SB1 has recovered again normally off, A.C. contactor 6 can not lean on auxiliary contact K1 energising again, because originally closed auxiliary contact K1 is reset to normally open along with the power-off of A.C. contactor 6, so now whole interchange Relay logic control system quits work.
The input power that shows DC power supply 7 is two power supply outputs of A.C. contactor 6; Show that the AC power of input is converted to DC power supply by DC power supply 7, and be connected with the state indication unit 3 being arranged on the manipulation table top at system synthesis Xian Kong center 1 by long-distance transmissions cable 4.Like this, when after distal portion system and equipment 5 power-off, the demonstration DC power supply 7 being connected with this state indication unit 3 will power-off, and now the indicator light of state indication unit 3 will knock out; In the time of distal portion system and equipment 5 normal work, the indicator light of this state indication unit 3 will normally show.
A.C. contactor 6 in the utility model can be also relay.
Although the present invention with preferred embodiment openly as above, embodiment is not of the present invention for limiting.Without departing from the spirit and scope of the invention, any equivalence of doing changes or retouching, belongs to equally the present invention's protection range.Therefore protection scope of the present invention should be taking the application's the content that claim was defined as standard.
