Description

Electrical outlet with security function {omitted}

The present invention relates to an "electrical outlet having a security function," and to a user's convenience by allowing a user to set a security function on an electrical outlet with only one-touch keys installed on the electrical outlet. In general, night thieves focus on the houses that are turned off from early evening in apartments and detached houses, and among them, the houses that are considered to be empty are robbed. Therefore, many people leave home with stand lights or ceiling lights when they are away from home for long periods of time, such as during holidays, or when they are expected to return home late. At this time, there is a lot of power consumption because 24 hours light is on, and there is anxiety that the house which is lit 24 hours can be monitored by thieves.

Accordingly, an object of the present invention devised to solve such a problem is to provide a method for enabling an electric outlet to perform a security function and an electric outlet having the same function by a user of an electric outlet by one-touch operation.

Features of the electrical outlet according to the present invention for achieving the above object is that when the security function is set according to the user's operation, the setting state is indicated by the display LED and judging day and night by the brightness sensor [CDS] to output the outlet during the day Turn off the output, and turn on the output for several hours (4-5 hours) from the early evening so that the lights in the outlet can be turned on. It includes the step of performing the security function to turn on the outlet output for 1 to 2 hours and then to turn off the outlet output when the day is bright. In addition, another feature of the electrical outlet with a security function according to the present invention is the security function setting key for setting the security function, the light emitting device [LED] for displaying the security function setting status, day and night discriminating the clock for 24 hours Includes configuration of brightness sensor and control microcomputer for operation. Therefore, the user of the electrical outlet having a security function according to the present invention can conveniently set the security state in one-touch.

Hereinafter, a preferred embodiment of the "electrical outlet having a security function" according to the present invention will be described in detail with reference to the accompanying drawings. Figure 1 is a connection diagram of a conventional electrical outlet, Figure 2 is a circuit diagram of an embodiment of an electrical outlet with a security function according to the present invention. In FIG. 2, reference numeral 1 denotes a power supply circuit block for driving an electrical outlet according to the present invention, and reference numeral 2 denotes a circuit block for detecting a phase of an AC input. Reference numeral 3 denotes a triac and drive circuit block for outlet output on / off, and reference numeral 4 denotes a microcomputer and a peripheral circuit block for centrally controlling the operation of the electrical outlet. K ₁ to K ₃ are first to third output outlets, the first and second outlets are general output outlets, and the third outlet is an output outlet capable of performing a security function. The first input terminal [I ₁ ] of reference 4 is an input terminal for detecting the phase of the AC input, the second input terminal [I ₂ ] is a security key input terminal, and the third input terminal [I ₃ ] detects the brightness. This is an analog input terminal. The first output terminal [O ₁ ] is an output terminal for controlling the ON [OFF] and [OFF] of the third outlet output, and the second output terminal [O ₂ ] is a light emitting element for displaying the security function setting state. [LED] Drive output terminal. When Low is output to the second output terminal, the LED [LED] is turned off and displays the security function setting status. When High is output to the second output terminal, the general status is displayed. High is output and the triac [TRC] is turned on [ON] so that the third output outlet [K ₃ ] is always on. Whenever the security key [SW] is inputted, the security setting state and the normal state are changed [toggle operation]. In the security function setting status [Security Mode], the on / off control of the third output outlet [K ₃ ] is controlled by a 24-hour clock in which the microcomputer [U ₁ ] senses brightness and operates and an on / off timer program installed in the microcomputer. do. The microcomputer [U ₁ ] operates the 24-hour clock by setting the midpoint of daytime [middle time between dawn and early evening] to 12 noon and the midpoint of night [middle between early evening and dawn] as 12 pm. In the security function setting, turn on the output of the third output outlet [K ₃ ] for 4 to 5 hours in the early evening, turn on the output [K ₃ ] for ₁ to 2 hours at dawn, and at night 12 Turn on or off briefly once or twice at the time of floodlighting. At other times, turn off the outlet [K ₃ ]. Therefore, when the user plugs the lamp into the third output outlet [K ₃ ], the electric outlet and the lamp according to the present invention can perform a security function only by one-touch operation. 3 is a flowchart showing a method of performing an anti-security function of an electric outlet according to the present invention. Check if the security key is input [S101], if the security key is input, switch the crime / general state [S102], display the crime / general state [S103], and check whether the current state is a crime state [ S104]. If the security key is not entered, the current state is checked without switching the security / general state [S104]. If the current state is not a crime state, the processing of key input ends and waits for a new key input. If the current state is a crime prevention state, the control microcomputer [U ₁ ] reads a 24-hour clock made by detecting the brightness to determine whether the current is day or night [S105]. If the current state is daytime, the outlet output is turned off [S106]. If the current state is nighttime, the outlet output is controlled on / off according to the night on / off timer program installed in the microcomputer [S107]. ]. 4 (1) shows that the microcomputer [U ₁ ] detects the day and night by detecting the brightness with the brightness sensor [CDS] and (2) of Figure 4 to perform the security function in the same way as described above A timing diagram for one embodiment is shown.

According to the electrical outlet having a security function according to the present invention as described above, when the user of the outlet plugs the lights into the outlet, the security function is set only by one-touch operation without additional clock adjustment and time reservation procedure. In this case, the electric outlet performs security functions by itself according to the on / off timer program installed on the control microcom and the 24-hour clock that detects and operates the brightness, and provides convenience to the user as well as extra protection against power failure. It does not require a battery, so it also provides the effect of value increase due to cost reduction.

Although the above has been illustrated and described with respect to preferred embodiments of the present invention, the present invention is not limited to the above-described embodiments, and various changes may be made without departing from the spirit of the invention as claimed in the claims of the present invention. Such changes are intended to fall within the scope of the claims.
