In this novel aerogenerator guard against theft and alarm system, described guard against theft and alarm system also has time-delay reset circuit, described time-delay reset circuit comprises reporting to the police for alarm host machine 3 and is serially connected with the two poles of the earth of electric supply installation after the time relay KT of time delay and the time relay KT1 for resetting after reporting to the police, time relay KT and time relay KT1 parallel connection with the normally opened contact KA-2 of latch-in relay KA; The normally closed contact KT-1 of described time relay KT and normally closed contact KT-2 and trigger switch 1 and latch-in relay KA phase are serially connected with the two poles of the earth of electric supply installation, and normally closed contact KT-1 and normally closed contact KT-2 is located at latch-in relay KA two ends; The normally opened contact KT1-1 of described time relay KT1 and normally opened contact KT1-2, described normally opened contact KT1-1 is located at the two ends of latch-in relay KA with normally opened contact KT1-2 and is connected with electric supply installation; After the described time relay KT1 delay adjustments time for latch-in relay KA provides inverse current and make latch-in relay KA return to trigger switch be triggered before state.
When normal power supplies module 6 is as power supply and when being triggered when trigger switch 1, latch-in relay KA starts working after obtaining electric signal, normally opened contact KA-2 closes, time relay KT and time relay KT1 obtains electric starting working, after time relay KT obtains the electric delay adjustments time, its normally closed contact KT-1 and normally closed contact KT-2 disconnects, after time relay KT1 obtains the longer setting-up time of electric time delay, normally opened contact KT1-1 and normally opened contact KT1-2 closes, and give latch-in relay KA reverse electric signal, make latch-in relay KA return to trigger switch be triggered before state, now normally opened contact KA-2 disconnects, time relay KT and time relay KT1 power-off, the normally closed contact KT-3 of time relay KT disconnects, alerting signal is cut off, alarm host machine quits work.
In this novel aerogenerator guard against theft and alarm system, described trigger switch 1 comprises normally opened contact SB and the normally opened contact SB-1 of interlock mutually, described normally opened contact SB-1 accesses terminal with the alerting signal of alarm host machine and is connected, and described normally opened contact SB is connected in series with latch-in relay KA phase.
In this novel aerogenerator guard against theft and alarm system, described standby power supply module 5 comprises accumulator E4 and solar energy photovoltaic panel 7, and described solar energy photovoltaic panel 7 is connected with accumulator E4 two ends by wire.
In the present embodiment, solar panels can be installed on the brandreth of fan engine room top anemoclinograph, and warning system and accumulator are installed on first segment tower barrel platform, destroy to prevent invasion personnel.
In this novel aerogenerator guard against theft and alarm system, described conventional electron power module 6 comprises relay K A2, and normally opened contact KA2-1 and/or the normally opened contact KA2-2 of described relay K A2 are connected in series mutually with standby power supply module.
In this novel aerogenerator guard against theft and alarm system, described latch-in relay KA also comprises normally closed contact KA-3, and described normally closed contact KA-3 is connected in series mutually with solar energy photovoltaic panel.
In this novel aerogenerator guard against theft and alarm system, described conventional electron power module 6 also comprises a latch-in relay KA1, and the normally closed contact KA1-1 of described latch-in relay KA1 and/or normally closed contact KA1-2 is located at or is located at respectively on the loop that conventional electron power module 6 is connected with alarm host machine 3.
In this novel aerogenerator guard against theft and alarm system, described alarm host machine 3 can be GSM alarm host machine, bus alarm host machine, GPRS network alarm main frame, CDMA burglar alarm main frame, zigbee networking alarm host machine or audible-visual annunciator.Preferably, alarm host machine 3 can be GSM main frame, configuration remote monitoring, propaganda directed to communicate, the function such as field alert, SMS alarm, telephone call, warning signal can report to the police in blower fan, also can to propaganda directed to communicate warnings by alarm center in the distance, reinforcement fright effect.
Specific works step of the present invention is as follows:
1, under normal operating mode:
By electrical network as conventional electron power supply 6 for warning system is powered, first by AC/DC changeover switch, alternating current is converted this power supply to the direct current suitable with alarm host machine 3.Simultaneously due to KA2-1, KA2-2 disconnect, KA-3 is normally closed, now accumulator E is in charging on daytime under the effect of solar energy photovoltaic panel, under the circulation of slightly leaking electricity night, keeps the state that battery electric quantity is full always.
If now there is people to open Damper for air-blower, (this signal is that crawl triggers to the universal travel switch SB of instantaneous trigger, just can trigger as long as open the door, SB-2 is that the independence of the same type of SB often opens auxiliary node), enabling signal receives the report for police service main frame 3 signals collecting place by SB-2, and alarm host machine 3 carries out phone and SMS alarm.
2, under the operating mode after blower fan power failure:
Relay K A1 and KA2 dead electricity, Switching Power Supply is not powered, and latch-in relay KA (can use magnetic latching relay or common double coil latch-in relay, but voltage circuit connection when resetting is slightly different, the present invention is for magnetic latching relay) auxiliary node KA-1, KA-2 often open, alarm host machine 3 dead electricity, the equal dead electricity of the time relay KT and KT1, now without any consumer.KA2-1, KA2-2 and KA-3 are normally closed, and accumulator E1 is connected to DC12V bus, but due to without electricity consumption of equipment, the current supply circuit of E1 is equivalent to open circuit, and are still continuing to accept photovoltaic panel charging.
Now once there be people to invade, enabling signal SB is triggered by crawl, and KT-1, KT-2 and KA2-3 are in normally closed, then latch-in relay adhesive keeping.KA-1 adhesive, KA1-2 is normally closed, and alarm host machine obtains electric startup.KA-3 disconnects, and solar panels stop accumulators E1 charging.KA-2 adhesive simultaneously, time relay KT obtains electric time delay (being set to 30 seconds), and KT-2 time delay adhesive, for the alarm host machine started provides alerting signal, completes phone and SMS alarm, and now KT-1, KT-2 time delay disconnects.
After completing phone and SMS alarm, time relay KT1 is as the use that automatically resets, KT1 obtains electric time delay (being set to 30 minutes), after alarm host machine runs 30 minutes, KT1-1, KT1-2 adhesive, and KT-1, KT-3 disconnect, then latch-in relay KA obtains a reverse voltage, reinstatement state.KA-1 and KA-2 often opens, and alarm host machine and each relay are all stopped power supply, and solar panels recover the pattern of accumulators E1 charging, ensures that battery electric quantity is sufficient, waits for triggering of next time reporting to the police.
The present invention, by arranging conventional electron power module and standby power supply module is that warning system is powered, when conventional electron power module makes warning system have the function of warning under the condition without power supply, improves the reliability of warning system dramatically; Wherein standby power supply module also has the function of automatic time-delay reset, ensures that standby power supply module has enough electricity to maintain the normal work of warning system, improves the reliability of warning system, have good promotional value largely.
The foregoing is only the preferred embodiment of the present invention, it should be pointed out that for the ordinary skill in the art, without departing from the principles of the present invention, can also make various deformation and improvement, this also should be considered within the scope of protection of the present invention.
