Description

The anti-toy alarm device of cable duct
Technical field
The present invention relates to a kind of anti-toy alarm device of cable duct.
Background technology
Short circuit power cut accident happens occasionally throughout the country as caused by toy, especially the time of the year when autumn changes into winter, and weather turns cold, Outdoor food is reduced, and toy often pierces hole(Room)Interior search of food, heating are passed the winter.Why they can smoothly enter electricity In cable ditch, control room and switch gear room, often these place in work progress just to toy leave enterable passage, Hole gap, crack between a door and its frame, window seam etc..Switch gear room, control room can in time be found due to the presence of periodical inspection and mouse sticking plate and be removed this A little uninvited guests.But the tour difficulty of switch gear room's cable duct is larger, and the cycle is longer, and there is no Mouse killing trap.Once there is toy Intrusion, it is difficult to be found in time, if stinging bad cable, scurries into switch cubicle, will seriously jeopardize the safe operation of equipment.Therefore, It is extremely urgent to solve this problem.
What national grid was promulgated《Substation management specification》[state's electricity is raw(2003)No. 387] in the defendance of relevant substation safety Strict regulations in system:Transformer station planted agent prevents that toy invades.
The content of the invention
It is an object of the invention to provide a kind of anti-toy of cable duct that can effectively monitor toy, prevent accident from occurring Alarm device.
The present invention technical solution be:
A kind of anti-toy alarm device of cable duct, it is characterized in that:Including pyroelectric infrared sensor, pyroelectric infrared sensor It is connected with AT89S52 single-chip microcomputers, sends monitoring signals to AT89S52 single-chip microcomputers, AT89S52 single-chip microcomputers are connected to GSM message biography Defeated module, pass through GPRS or short message way remote transmission data;Pyroelectric infrared sensor seals installed in switch gear room's cable duct Stifled place;AT89S52 single-chip microcomputers are connected with voltage stabilizing chip power module.
The voltage stabilizing chip power module is the circuit shape that regulated output voltage is carried out by introducing depth negative voltage feedback Formula.
The present invention can effectively monitor toy, in time alarm, prevent accident.
Brief description of the drawings
The invention will be further described with reference to the accompanying drawings and examples.
Fig. 1 is the structured flowchart of one embodiment of the invention.
Fig. 2 is voltage stabilizing chip power circuit schematic diagram.
Embodiment
A kind of anti-toy alarm device of cable duct, including pyroelectric infrared sensor 1, pyroelectric infrared sensor with AT89S52 single-chip microcomputers 2 connect, and send monitoring signals to AT89S52 single-chip microcomputers, AT89S52 single-chip microcomputers are connected to GSM message transmission Module 3, pass through GPRS or short message way remote transmission data;Pyroelectric infrared sensor blocks installed in switch gear room's cable duct Place;AT89S52 single-chip microcomputers are connected with voltage stabilizing chip power module 4.
The voltage stabilizing chip power module is the circuit shape that regulated output voltage is carried out by introducing depth negative voltage feedback Formula.Work as voltage pulsation(Or the change of load resistance)When making output voltage U0 risings, sampling voltage Un increases, due to voltage-stabiliser tube Voltage Uz is constant, the input voltage Unp (=Un-Up=Un-Uz) increases of amplifier, reduces A output(Adjust the base stage electricity of pipe Potential drop is low), and make the adjustment pipe T low increase of c-e pressure drops, so as to adjust output voltage U0(=UI-Uce)Reduce.Make output voltage Obtain stabilization.Circuit is to carry out regulated output voltage by introducing depth negative voltage feedback.

Claims (2)

1. a kind of anti-toy alarm device of cable duct, it is characterized in that:Including pyroelectric infrared sensor, rpyroelectric infrared sensing Device is connected with AT89S52 single-chip microcomputers, sends monitoring signals to AT89S52 single-chip microcomputers, AT89S52 single-chip microcomputers are connected to GSM message Transport module, pass through GPRS or short message way remote transmission data;Pyroelectric infrared sensor is arranged on switch gear room's cable duct At closure;AT89S52 single-chip microcomputers are connected with voltage stabilizing chip power module;
The voltage stabilizing chip power module is the circuit form that regulated output voltage is carried out by introducing depth negative voltage feedback;When When voltage pulsation or the change of load resistance make output voltage U0 risings, sampling voltage Un increases, due to the voltage Uz of voltage-stabiliser tube It is constant, input voltage Unp=Un-Up=Un-Uz increases of amplifier, reduce A output, that is, adjusting the base potential of pipe reduces, And make the adjustment pipe T low increase of c-e pressure drops, reduce so as to adjust output voltage U0=UI-Uce, output voltage is obtained stabilization; Circuit is to carry out regulated output voltage by introducing depth negative voltage feedback.
