Description
Technical field
The present invention relates to a kind of control circuit of electromagnet, specifically a kind of control circuit of elevator brake system.
Background technology
In the elevator safety accident about 80% is brake troubles.A major cause of brake troubles is that the contact adhesion takes place in the brake loop of elevator brake system.After the contact of change-over switch sticks together, will make the drg can't brake application, elevator brake system thereby malfunctioning causes elevator that serious accidents such as car, the end of rushing to summit or squat take place to slip.And the major cause that the contact of change-over switch sticks together is because brake coil is serially connected in the brake loop, this just causes and flows through the contact that exciting current brake coil, bigger has flow through change-over switch simultaneously, makes the contact arcing take place and adhesion in moving process.Therefore, the control circuit structure of existing elevator brake system can't solve the problem of contact adhesion in the brake loop.
Summary of the invention
Purpose of the present invention just provides a kind of control circuit of elevator brake system, fundamentally to solve the contact adhesion problems in the brake loop, improves elevator reliability of operation and safety.
The present invention is achieved in that a kind of control circuit of elevator brake system, by door lock relay DJ, band-type brake contactless switch ZJ, current-limiting resistance R
1Become brake loop with 1, the 2 pin series connection of isolation control switch CK, the mouth 3,4 of described isolation control switch CK and the input end of brake controller CT join, and wherein 4 pin are simultaneously through resistance R
2Meet direct supply DC, 3 pin of described isolation control switch CK and the ground terminal of described brake controller CT be grounding jumper G altogether, is connected with the series loop of brake coil L and operation contactless switch CJ at the mouth of described brake controller CT.
Described disconnector CK is bi-directional light electric coupler, photoelectrical coupler, voltage changer, voltage transformer or relay.
One of key point of control circuit of the present invention is to be provided with the brake loop relatively independent with brake coil L.In this circuit, be in series with devices such as door lock relay DJ, band-type brake contactless switch ZJ and current-limiting resistance, and brake coil L is separated from brake loop, is directly connected in the output loop of brake controller CT; By disconnector CK is set, brake loop is carried out the conversion of level signal and separating of strong and weak electricity with brake controller CT.When brake loop send band-type brake or the command signal that declutches after, by the level signal change-over circuit, can to brake controller CT send one with TTL circuit or the CMOS gate circuit level signal of compatibility mutually, make brake controller CT action, the on/off of control brake device coil, thus make drg implement corresponding band-type brake or the operation of declutching.Because brake coil separates with brake loop, make the electric current and the brake loop that flow through brake coil irrelevant, the effect of brake loop only is to provide the light current control signal to brake controller CT, therefore, the electric current of brake loop just can be dropped to tens of milliamperes by original several amperes, avoided because of big electric current flows through the contact arcing phenomenon that is caused, thereby overcome the problem that the contact sticks together effectively, improved the safety of elevator operation.
Two of key point of the present invention is that operation contactless switch CJ has been connected on the output loop of brake controller CT, and operation contactless switch CJ and brake coil are in series.Demonstrated fully the preceence control of operation contactless switch CJ, no matter promptly each contact is in any state in the brake loop, as long as operation contactless switch CJ disconnects, just make the brake coil forced interruption, elevator brake system is unconditionally finished the brake application braking maneuver, avoided the generation of the elevator safety accident that caused because of the brake loop failure and other reasons, the functional reliability of elevator and elevator brake system is greatly improved.It is the not available outstanding advantage of control circuit of present various elevator brake systems that this point improves, and is significant for the generation of taking precautions against the elevator safety accident.
Description of drawings
Fig. 1 electrical schematic diagram of the present invention.
The specific embodiment
As shown in Figure 1, the present invention is connected in series by two input ends 1,2 of door lock relay DJ, band-type brake contactless switch ZJ, current-limiting resistance R1, isolation control switch CK, constitutes brake loop; The operating voltage of brake loop is applied to A, B two ends, and this voltage can be to exchange 110/220V, also can be direct current 110/220V.The signal input part of two mouths, 3, the 4 one termination brake controller CT of isolation control switch CK is simultaneously through current-limiting resistance R
2Connect the 15V direct supply, the other end is a ground terminal, grounding jumper G.Brake controller CT can adopt the conventional control circuit structure, and the ground terminal of its ground terminal and isolation control switch CK is grounding jumper G altogether.Brake coil L and the mouth that is connected brake controller CT after operation contactless switch CJ connects.
Brake coil L among the present invention can be one group, two groups or more coil; Two groups of above coils can be to be connected in parallel, and also can be to be connected in series.
The present invention thereby has alleviated the current loading of brake loop because the electric current that flows through brake coil L has nothing to do with brake loop, has improved the reliability of all mechanical contact switch of brake loop.
In brake controller CT, can use the noncontacting switch of silicon control class to carry out voltage switching and regulating and controlling voltage, to guarantee the high reliability of elevator brake system power circuit.
Working process of the present invention is:
Door lock relay DJ in Fig. 1 and operation contactless switch CJ all after the closure, have just satisfied the sufficient condition that drg declutches; If the controlled closure of band-type brake contactless switch ZJ has just satisfied the necessary condition that declutches.At this moment, the input end of isolation control switch CK gets electric, the mouth output low level, and brake controller CT exports driving voltage and sustaining voltage under this low level control.Because operation contactless switch CJ is closed, this voltage just directly acts on brake coil L, finishes the drg action of declutching.
The brake application braking of drg is to overlap independently circuit control by two: the first is by door lock relay DJ, band-type brake contactless switch ZJ in brake loop control.Promptly when among door lock relay DJ and the band-type brake contactless switch ZJ any one contact open being arranged, all satisfy the sufficient and necessary condition of brake application braking, the input end dead electricity of isolation control switch CK, mouth output high level, brake controller CT quits work, no-voltage output, brake coil L no current flows through, and finishes the brake application action.It two is by operation contactless switch CJ control, and the operation contactor control has preceence.That is to say that even the contact of door lock relay DJ and band-type brake contactless switch ZJ does not disconnect, as long as the contact open of operation contactless switch CJ has just satisfied the sufficient and necessary condition that brake application is braked, brake coil L unconditionally finishes the brake application braking promptly by forced interruption.
