Technical field
The utility model belongs to accessory equipment of pump station, relates in particular to a kind of pump house theft preventing installation.
Background technology
The geographic position of pumping plant is more remote, and is stolen easily for equipment such as the transformer in the pumping plant, motor, water pump and accessory thereof, especially in night.
Present alarm is made up of sensor (probe), processor (single-chip microcomputer), signal projector several modules such as (GSM) as wireless (GSM) alarm anti-theft.When object entered the investigative range of sensor, sensor produced high (low) level signal, and the signal after handling through single-chip microcomputer sends on mobile phone or the fixed telephone subscriber by gsm module, thereby reached the effect of warning.Therefore, the warning effect of alarm directly is subjected to the influence of the Effect on Detecting of sensor.But all there is certain defective in probe on the market now, can't distinguish the interference of human body and toy as the active infrared probe; The passive infrared probe is subjected to the interference of temperature easily; Infrared correlation probe can't be deployed troops on garrison duty on a large scale, and range of application is restricted etc.Generally wireless (GSM) alarm anti-theft fails the alerting signal that sensor produces is carried out effective analyzing and processing.The defective that exists: (1), can't effectively distinguish human body and toy, antijamming capability is relatively poor; (2), be easy to generate false alarm during daytime, need artificial alarm, the troublesome poeration of turn-offing; (3), transformer does not have independent anti-theft feature, easy having things stolen.
Summary of the invention
Relatively poor for the antijamming capability that overcomes existing alarm, as can not to distinguish human body and toy deficiency, the utility model provide the pumping plant alarm that a kind of antijamming capability is strong, can effectively distinguish human body and toy.
The technical scheme that its technical matters that solves the utility model adopts is:
A kind of pumping plant alarm, comprise the human body sensor that is installed in the pumping plant, alarm processor and alarm, the output of described human body sensor connects alarm processor, described alarm processor comprises the signal receiving module of the induced signal that is used for recipient's body sensor, be used for sending to alarm the alarm module of alarm command according to the induced signal of human body sensor, the output of described alarm module connects alarm, described alarm processor also comprises the time delay module that is used for exporting to alarm module induced signal when the described induced signal duration reaches the capping value, described signal receiving module connects time delay module, and described time delay module connects alarm module.
Further, described alarm processor also comprises and being used for after double induced signal does not reach the capping value, according to default gear value, upper limit adjusting module with a gear value of higher limit downward modulation, described signal receiving module connects upper limit adjusting module, and the output of described upper limit adjusting module connects time delay module.
As preferred a kind of scheme: described alarm is provided with starting switch, described alarm processor also comprises the time switch module that is used at the turn-off time disconnection starting switch of closed starting switch of the opening time of setting, setting, and described time switch module connects described starting switch.
Further, described alarm processor also comprises the Preset Time module that is used to set described opening time, turn-off time, and described Preset Time module connects described time switch module.
As preferred another scheme: described pump house theft preventing installation also comprises three step-down rectifier modules of the three-phase circuit that is installed in transformer, described three step-down rectifier modules connect alarm processor, described alarm processor also comprises the single-phase alarm module that sends single-phase alarm command behind the power-off signal that is used to detect one of them step-down rectifier module to alarm, be used for sending the three-phase alarm module to alarm after three step-down rectifier modules are successively sent power-off signal detecting, described three step-down rectifier modules connect single-phase alarm module and three-phase alarm module, and the output of described single-phase alarm module and three-phase alarm module is connected alarm.
Further, described alarm processor also comprises the GSM signal emission module, and the output of described alarm module connects the GSM signal emission module, sends to the supvr by the GSM network, is convenient to the supvr and manages.
Further again, described human body sensor comprises infrared transmitter and infrared remote receiver, and described infrared transmitter, infrared remote receiver align installation.
Technical conceive of the present utility model is: add a signal pre-processing module between sensor and processor, in the continuous several seconds (2 seconds), the detectable signal that pretreatment module produces sensor carries out unified Analysis to be handled,, detectable signal is transferred to the processor processing of reporting to the police if meeting the physical activity rule, if do not meet the physical activity rule then shield as undesired signal.
In the signal pre-processing module, the experiment proved that after human body enters the probe induction region and can produce the induced signal of growing (2 seconds), and the induced signal duration that the interference of toy produces is lacked (continuous below 1 second), design reaches the several seconds (2 seconds) when continuously high (low) level of probe signal end for this reason, height (low) level is delivered to processor, the processing of reporting to the police.
And can be according to the sensitivity of undesired signal adjustment probe: when continuously high (low) level of probe signal end less than (2 seconds), the signal preprocessor shielded signal, and in counter, be recorded as false positive signal, when false positive signal greater than 2 twice the time, signal preprocessor feedback regulation signal, produce the fine setting of one-time efficacious sensitivity, finely tune always, it (is 1.9 seconds with fine setting in 2 seconds for example that each fine setting will progressively be shortened in the longer time limit, each fine setting descended 0.1 second), up to reaching best sensitivity, so just can not need artificial intervention and directly reach best sensitivity effect.
For pumping plant, the antitheft time does not then need alarm to open mainly at night daytime, as the opening on daytime, then causes false alarm easily; Because be necessary very much to come automatic setting by opening time and turn-off time are set; Avoid manual operation.
For the transformer of pumping plant, all charged under the outlet side of transformer or the inlet wire side normal condition, can monitor single-phase and three-phase respectively, can distinguish and cut off or large-area power-cuts by the people.As large-area power-cuts, then three-phase has a power failure simultaneously, does not then send alarm signal; Successively have a power failure as single-phase power failure, three-phase, then be judged as the people, have stolen possibility for cutting off the water pump inlet wire; Send to the supvr by the GSM network, be convenient to the supvr and manage.Function with time switch and teleswitch significantly reduces the waste and the consumption of electric of resource.
The beneficial effects of the utility model mainly show: 1, antijamming capability strong, can effectively distinguish human body and toy, improve warning efficient; 2, can regulate the sensitivity of probe according to undesired signal; 3, can open and the turn-off time intelligent degree height by the automatic setting alarm; 4, advance/outlet side electriferous state by the monitoring transformer, have anti-theft feature, prevent that effectively transformer is stolen.
