4, remote control operation (open/stop)

Remote-control operation mode can change, such as relatively according to actual application feature: passive contact non-self-lock-ing controls, passive self-locking Control, the control of active non-self-lock-ing, active contact are from lock control etc..Described herein it is: active voltage DC24V trigger-type controls Pattern；

A is far controlled and is opened: when outside DC24V trigger voltage is through No. 1 terminal of patch panel X1 and No. 2 terminal DC24V relay K J1 Coil obtains electric → remote control lock SA2(lock-controlled switch, plays safeguard protection effect, and this switch is two kinds of orientation states: left-handed 45 degree is pass → forbid, contact disconnects；Dextrorotation 45 degree for opening → allowing, the closing of contact) be that permission state → normally closed Guan Bi → KJ1 of KJ2 is normal Make war Guan Bi → KA303 and the line of adhesive → KA303` normally opened Guan Bi → self-locking KA303 and KA303` while KA303` coil Circle；KA303 normally opened some Guan Bi → PLC1[I0.5=1] KA303 normally opened contact Guan Bi → PLC2[I0.5=1 simultaneously]；

2 groups of PLC input port I0.5 of b are simultaneously entered signal, and software can distinguish and take turns starting 2 groups of pump motors, (it voluntarily So it is proper in order to make every water pump all use for needing 2 groups to take turns starting).Once it is determined that after startup group any one group PLC can output signal voluntarily, when system detects after the startup order performed starts unsuccessfully, can automatically turn within 20 seconds It is changed to another set start, and points out trouble light and backstage to record failure condition, its I group of Starting mode and herein 2 on panel Nearly control operation b is the same, as its II group of Starting mode starts I group/II group conversion b with herein 3；

C is far controlled and is stopped: when outside DC24V trigger voltage is through No. 3 terminals of patch panel X1 and No. 4 terminal DC24V relays KJ2 coil obtains electric → power down through allowing the remote control lock normally closed disconnection → KA303 of SA2 → KJ2 and the KA303` coil of state while, 2 groups of PLC input ports [I0.5=0], software performs halt command automatically, its I group of stopping process and herein 2 closely control operation c mono- Sample, as its II group of stopping process starts I group/II group conversion b with herein 3.So just complete whole remote control process One loop control；

5, test is certainly opened

Owing to Fire Control Cabinet can not often be run, so every month will do one-shot test for pump motor, in case Equipment for a long time need not and cause faults such as making moist, also for checking potential faults in advance.Touch at this equipment man-computer interface Can arrange the concrete startup time of each of which moon, dwell time on screen, accurate unit is: the second；

A is when certainly opening after the wherein time of testing meets, and system can shift to an earlier date 10 minutes prompting sound and light alarms per minute, then performs to open Dynamic order → PLC1[Q0.3=1] → certainly open lockhole switch SA1 for allowing position (the most mainly to play protection to make with above SA2 With) → KA153 coil obtains electric, KA153 internal two groups of normally opened contacts Guan Bi triggers the most simultaneously, and execution program afterwards is with herein 4 remote control operation b are the same；

B when from the start and stop time meet after, PLC1[Q0.3=0] → through allow state certainly open lock → KA153 coil losing electricity, Its normally opened contact is made to disconnect → trigger PLC1[I0.5=0] and PLC2[I0.5=0] its I group of stopping process control near with this paper 2 operation c Equally, as its II group of stopping process starts I group/II group conversion b with herein 3.So just complete from opening the one of process of the test Individual circulation.

6, emergency starting device force start

When all of control loop all cannot work so that it is normal operating cannot start pump motor, and now have to Run pump motor rescue and relief work, main power source power normal in the case of, emergency starting device force start device just Can be controlled to force to put into handle, successfully start up pump motor rescue and relief work and (meet country by the operator having permission in 30 seconds Standard GB50974 → 2014 " fire water-supply and hydrant system technical specification " the 11.0.12 article (strong article) specify: fire pump Switch board should arrange mechanical emergency and open pumping function, fire pump switch board proposes a completely new concept → mechanical emergency and opens pump Function).The operator now having permission key unlocks the operation handle of any one group of two groups of strong opening devices of group (at cabinet manipulation in vitro A padlock it is mounted with at handle) directly operation handle is up pushed into and opens by force position；

Owing to there is no the standard gallery to this device in GB picture library, what in accompanying drawing, " force start " character line connected is one Machinery energy storage mechanism device linkage contact forces the simplification figure of adhesive；

A selects I group to open by force: when operation handle travel to before fast energy storage mechanism action → handle position detection switchs LS1 adhesive The detection switch LS2 adhesive of → handle position, power supply is through electric fuse FU1 → normal to LS1 → LS2 → KC160 coil obtains electric → KC160 The control loop normally opened Guan Bi → power supply of disconnection → KC160 of close point disconnection → KM1 and KM3 coil and system is through FU1 → KC160 The normally opened point of Guan Bi is powered directly to KM1, KM3, and the other end of one group of KC160 normally opened point control KM1, KM3 coil is straight simultaneously Connect and power supply N line Guan Bi, if the now coil of KM1 and KM3 or good, adhesive KM1, KM3 before will being faster than that machinery is strong and closing Main contact, which increase the synchronicity of combined floodgate, speed also has safety (electricity close a floodgate be faster than machinery combined floodgate).Simultaneously The normally closed point of KC160 disconnects → cuts off I group of control ring current with II group, the simultaneously normally opened Guan Bi → KA305 coil of KC160 Electric → KA305 normally opened some Guan Bi → PLC1[I0.7=1], PLC2[I0.7=1] locking PLC(reach one mutual with strong throwing device Lock purpose, it is considered to be some unreliable factor or unstable factor make control loop occur intermittent defect causes control Conflict)；If now KM1 or KM3 coil is broken or goes wrong in the emergency flight control loop such as KC160, then machinery is strong Open and drawing KM1, KM3 contact will be forced to make it force adhesive to be that pump motor powers (open by force is to directly initiate)；

B shuts down 1, presses any stop botton SB2 or SB4 → normally opened Guan Bi → power supply of this button interior on panel through insurance The silk normally opened point of FU3 → stop button (when pressing close) → strong opening device tripping coil QT1 obtains electric adhesive trip link → open by force Device dropout → KM1, KM3 armature lose pulling force separating brake；

C opens I group by force handle and down pulls → arrive and the position handle of mechanical trip will trigger the normally opened point of travel switch LS5 → LS5 Guan Bi → power supply obtains electric dropout through electric fuse FU1 → LS1 → LS5 → QT1 coil, if now tripping coil QT1 again without Thread off, continue down spanner handle can by force mechanical trip (preferential use tripping coil be in order to increase the convenience of operation, its Effect is as mechanical trip)；

D selects II group to open by force: when operation handle travel to before fast energy storage mechanism action → handle position detection switch LS3 suction The detection switch LS4 adhesive of conjunction → handle position, power supply is through electric fuse FU2 → obtain electric → KC260 to LS3 → LS4 → KC260 coil The control loop normally opened Guan Bi → power supply of disconnection → KC260 of normally closed disconnection → KM5 and KM7 coil and system through FU2 → The normally opened point of KC260 Guan Bi is powered directly to KM5, KM7, another of one group of KC260 normally opened point control KM5, KM7 coil simultaneously End directly closes with power supply N line, if the now coil of KM5 and KM7 or good, will be faster than machinery strong close front adhesive KM5, The main contact of KM7, which increases the synchronicity of combined floodgate, speed also has safety (electricity close a floodgate be faster than machinery combined floodgate).Simultaneously The normally closed point of KC260 disconnects → cuts off I group of control ring current with II group, the simultaneously normally opened Guan Bi → KA305 coil of KC260 Electric → KA305 normally opened some Guan Bi → PLC1[I0.7=1], PLC2[I0.7=1] locking PLC(reach one mutual with strong throwing device Lock purpose, it is considered to be some unreliable factor or unstable factor make control loop occur intermittent defect causes control Conflict)；If now KM5 or KM7 coil is broken or goes wrong in the emergency flight control loop such as KC260, then machinery is strong Open and drawing KM5, KM7 contact will be forced to make it force adhesive to be that pump motor powers (open by force is to directly initiate)；
