The breakdown judge structural scheme of mechanism that Fig. 2 provides for this utility model.
Detailed description of the invention
As shown in Figure 1, the bus control system of the remote control valve 4 of the present invention, including computer 1, control centre 2, power supply box 3 and multiple remote control valve 4, described remote control valve 4 is provided with control unit, control unit main body is integrated circuit board, described breakdown judge mechanism is respectively provided with auxiliary reclay K1 and auxiliary reclay K2 for the remote control valve of its carried out breakdown judge, auxiliary reclay K1 and auxiliary reclay K2 is connected on the power supply circuits of remote control valve control unit, electric current enters to go out from another auxiliary reclay from an auxiliary reclay, the work electricity consumption of remote control valve control unit is from power taking between middle relay K 1 and auxiliary reclay K2；
Integrated circuit board is provided with CANBUS control unit；Described power supply box 3 is connected by the power unit of power line 5 and remote control valve 4, and control centre 2 is connected by data wire 6 and multiple control unit.
As in figure 2 it is shown, power supply is by forward flow during a whole set of remote control valve 4 system worked well situation, first pass through the K1 of executor 1, then through the K2 of executor 1, then the K1 towards executor 2, then lead to the K2 of executor 2, so continuing up down, K1 and K2 is normally-closed contact.Described auxiliary reclay K1 and auxiliary reclay K2 is configured in power supply circuits, and when breaking down in system, power supply circuits are avoided trouble point and again formed two current supply circuits before and after it.
Described breakdown judge mechanism can be used for electric-liquid type remote control valve 4, fluid pressure type actuator, electrodynamic type actuator, pneumatic actuating mechanism or waterpower actuator.
If as in figure 2 it is shown, there is open circuit conditions in A point source line 5, then the power supply of forward flow just send after having arrived remote control valve 100 less than remote control valve 200, according to the data that data wire 6 feeds back, such computer 1 system just can interpolate that remote control valve 200 does not have electricity.Because remote control valve 200 is backward all without signal time computer 1 is patrolled and examined.This computer-chronograph can judge to make prompting according to corresponding, and prompting interface can explicitly point out power line 5 open circuit between remote control valve 100 and remote control valve 200.Computer can send the auxiliary reclay K2 coil adhesive K2 main contacts of Data Control remote control valve 100 and disconnect, forward power supply is made to be only sent to remote-controlled valve 100, simultaneously, computer can control reverse electrical source and connect, remote control valve 200 is sent data to so that the auxiliary reclay K1 of remote control valve 200 disconnects by data wire.So, whole system can get around open circuit A point according to breakdown judge, recovers the work of system-wide remote control valve.
If there is short-circuit conditions in A point source line 5; the overcurrent protective switch being so arranged in forward power supply place can cross stream jumping electricity; switch jumping electricity from being short-circuited to and be about about 100mS movement time; now valve remote circuit system jumps electric protection; the short circuit of computer 1 system prompt system somewhere; computer 1 can point out operator close short circuit overcurrent protection switch, operator point out power turn-on to switch according to computer 1.Switch to jump again from power turn-on and between electric protection, have the 100ms time.Computer 1 utilizes this time to send self-inspection order, would not have feedback data after remote control valve 100, because remote control valve 100 is not below owing to power supply short circuit has power supply.At this moment the overcurrent protective switch of forward jumps electricity again, computer 1 prompting according to just now to patrol and examine result already known be that power line 5A point between remote control valve 100 and remote control valve 200 is short-circuit.Computer can point out operator to close forward on and off switch again.
Simultaneously, computer 1 can send an order to the control unit of remote control valve 100, command context is turned off the auxiliary reclay K2 of remote control valve 100, the movement time of auxiliary reclay has only to 10mS, such power supply just normally from forward stream to remote control valve 100, can make the remote control valve 100 forward can both normal operation；Then computer can control reverse overcurrent protective switch and closes; simultaneously; computer 1 sends the order of an auxiliary reclay K1 cutting off remote control valve 200 by bus system to remote control valve 200, and the power supply of such reverse flow can be transported to remote control valve 2 always.
By operation above, native system can not only judge that whole system where occurs in that power line 5 short trouble, additionally it is possible to by being arranged in K1 and the K2 of control unit, trouble point is separated so that whole system can continue to Emergency use.
The foregoing is only specific embodiment of the utility model, but architectural feature of the present utility model is not limited thereto, any those skilled in the art is in the field of the invention, and change or the modification made all are encompassed among protection domain of the present utility model.
This utility model can be applied equally to the data wire system of this valve remote control system.
