The invention relates to a special electricity larceny prevention device of an induction lamp illuminating system. The device is characterized in that the device is formed by connecting an electronic time delay control circuit and a divide-shut brake relay circuit, wherein the electronic time delay control circuit comprises a singlechip and a current sampling circuit and is connected with the divide-shut brake relay circuit through a singlechip. According to different characteristics of induction lamp illumination and electric current loads of living electricity for residents, a manner that the electronic time delay control circuit controls a divide-shut brake relay is used, so that power supply of the induction lamp illuminating system is not suitable for the living electricity, and electricity larceny behaviors can be effectively prevented; and at the same time, the device is simple in structure and high in environmental adaptability.
Description
Technical field
The present invention relates to a kind of anti-electricity-theft device, particularly the special-purpose anti-electricity-theft device of a kind of sense light illuminator.
Background technology
At present, the common parts such as corridor in many residential buildings building all use sense light illumination, and under normal conditions, sense light goes out the special circuit power supply after by the concentrated gas meter box master switch, supply line adopts " trunk formula " mode of connection, and each floor sense light is connected on main line.Sense light all belongs to communal facility, and its electric energy that consumes is generally shared by public, has just occurred that therefore some are connected to power consumption equipment in family the situation of the enterprising electricity of committing theft of sense light supply main.Although can judge the user by the stealing of corridor sensing lamp from the size of current of the miniature circuit breaker side of controlling sense light, determine concrete stealing position and electricity theft prevention very difficult problem really.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, provide a kind of sense light illuminator special-purpose anti-electricity-theft device.
The object of the present invention is achieved like this: the special-purpose anti-electricity-theft device of a kind of sense light illuminator, it is characterized in that it is connected and composed by electronic delay control circuit and divide-shut brake relay circuit, electronic delay control circuit is is wherein connected and composed by single-chip microcomputer, current sampling circuit, and the electronic delay control circuit is connected with the divide-shut brake relay circuit by single-chip microcomputer.
The electronic delay control circuit detects load current in sense light illuminator supply line, when this load does not meet the normal laws of use of sense light, send action command to the divide-shut brake relay circuit, the divide-shut brake relay normally closed contact disconnects, and power supply stops, after the default time, divide-shut brake relay automatic closing, restore electricity, if the after-current load that restores electricity is still undesired, the electronic delay control circuit after Preset Time, is controlled the divide-shut brake relay circuit and is continued action., by repeatedly connecting and cut off power supply circuits, make normally electricity consumption of electricity filching person.
The present invention is according to the different characteristics of sense light illumination with the resident living power utility current capacity, utilize the electronic delay control circuit to control the mode of divide-shut brake relay, make the power supply of sense light illuminator no longer be suitable for household electricity, thereby can make electricity filching person helpless abandon of steal sense light illuminalive power-supply for household electricity, effectively electricity theft prevention behavior; Simultaneously it is simple in structure, volume is little, easy to install flexibly, low in energy consumption, accommodative ability of environment is strong.
Description of drawings
Fig. 1 is circuit theory diagrams of the present invention.
Embodiment
The invention will be further described below in conjunction with accompanying drawing:
As shown in Figure 1, square frame 1 is divide-shut brake relay circuit of the present invention, and it consists of relay SRD, diode D1, triode Q1, protective resistance R9.The effect of diode D1 is to guarantee that on relay SRD coil, institute's making alive is forward voltage; Triode Q1 is switching tube; CB is relay normally closed contact, and CK is relay normally open contact, and DC is the power supply input.
Square frame 2 is the electronic delay control circuit, and it consists of current sampling circuit and single-chip microcomputer STC, and current sampling circuit is is connected and composed by Current Transmit, rectifier bridge U1, triode Q2, resistance R 7, R8 and capacitor C 5.Current Transmit in current sampling circuit with relay after electrical appliance be little electric current with voltage-current transformation after, output to rectifier bridge U1 from 1,2 terminals, the AC signal that rectifier bridge will be inputted is converted to direct current signal, from 3,4 terminals outputs; Triode Q2 is switching tube, and resistance R 7, R8 and capacitor C 5 form the accessory circuit of Q2, and effect is to the direct current signal rectification of rectifier bridge 3,4 terminal outputs and adjusts current parameters.When the electricity consumption electric current of electrical appliance after relay surpassed set point (0.5A left and right), the direct current signal of rectifier bridge 3,4 terminal outputs made Q2 enter saturation condition, and Q2 connects single-chip microcomputer P3.5 pin the signal input, and single-chip microcomputer starts timing.Single-chip microcomputer KZ pin is connected with the divide-shut brake relay circuit, and after it sent control signal, Q1 entered saturation condition, small-sized divide-shut brake relay coil loop conducting, coil motion.
The VCC pin of single-chip microcomputer is the power supply input pin, and the GND pin is grounding leg, and button KEY is program replacement button, with the GND pin, is connected, and when button was pressed, single-chip microcomputer restarted.
Square frame 3 and square frame 4 are respectively that working station indicator circuit of the present invention and Single Chip Microcomputer (SCM) program write port device.
The course of work of the present invention is: when device of the present invention is zero load, and relay normally closed contact CB adhesive, whole device is in conducting state.When the latter linked electrical appliance electricity consumption of apparatus of the present invention, current sampling circuit output direct current signal enters single-chip microcomputer P3.5 terminal, single-chip microcomputer starts timing, after surpassing the plug-in Preset Time, that is during the electrical appliance multiplexing electric abnormality, Single-chip Controlling terminal KZ sends control signal, after the divide-shut brake relay circuit receives control signal, the actuating of relay, normally closed contact CB disconnects, normal opened contact CK adhesive, end the power supply to load.After load supplying was ended, single-chip microcomputer P3.5 terminal was inputted without direct current signal, and Single-chip Controlling terminal KZ is after the plug-in Preset Time, and control signal stops output, and relay status recovers, normally closed contact CB adhesive, and normal opened contact CK disconnects, and recovers normal power supply.If after the recovery normal power supply, the load electricity consumption still occurs extremely repeating above-mentioned flow process.
