According to the configuration of the present invention described above, it is convenient to provide convenience, high efficiency energy equipment, increase the installation efficiency during wiring work, and to manage the number of people entering and leaving in a certain space to increase safety accidents and control efficiency A power saving switch can be provided.

Hereinafter, with reference to the accompanying drawings will be described the structure and effect of the power control switch having an automatic mode function according to the present invention.

Figure 2 shows a wiring diagram of a power control switch having an automatic mode function according to the present invention.

As shown in FIG. 2, in the system of the power control switch according to the present invention, the light emitting sensor unit 203 and the light receiving sensor unit 204 are installed in both door frames 201 and 202 of the door, and the light emitting sensor unit 203 is provided. Control unit 205 is configured to automatically perform the on-off of the first and second power supply (light or fan, 206, 207) by detecting the entrance and exit of the person by the light receiving sensor unit 204). The control means 205 may be directly supplied with external power.

Sensors used in the light emitting sensor unit 203 and the light receiving sensor unit 204 are preferably infrared sensors.

The light emitting sensor unit 203 may include a light emitting sensor 203a and a first microcomputer 203b, and the light receiving sensor unit 204 includes a first light receiving sensor 204a and a second light receiving sensor 204b and a second light source. It may be configured as a microcomputer 204c.

The light emitting sensor 203a and the first and second light receiving sensors 204a and 204b are installed in parallel to face each other based on the door door frame.

First, the first and second light receiving sensors 204a and 204b mounted to correspond to the light emitting sensor 203a are sequentially blocked by infrared rays as a person enters and exits through the doorway. In other words, if a person does not pass, infrared light is always received and the light receiving sensor is blocked as the person passes between the light receiving sensor and the light emitting sensor sequentially from the light receiving sensor located on the approaching side of the light receiving sensor.

As the light reception of the infrared light is blocked, the first and second microcomputers 203b and 204c are first blocked by the infrared light blocking of the first light receiving sensor 204a and the second light blocking sensor 204b is followed by infrared blocking. When it is determined that the user enters through the entrance door, the signal is sent to the control means 205. On the contrary, when the infrared blocking of the second light receiving sensor 204b is preceded and the infrared blocking of the first light receiving sensor 204a is followed, It is determined that the person exits through the door and sends the signal to the control means 205.

In addition, the first and second microcomputers 203b and 204c include counters (not shown) to counter the number of persons entering and exiting the data and transmit the data through the data cable 208. In this case, when several people enter or leave a space, the number of people entering and leaving the room is counted so that the internal power supply (light or fan, etc.) can be turned off when the last person leaving the room It can be a configuration.

In the light emitting sensor unit 203 and the light receiving sensor unit 204, a microcomputer is built in and analyzes and processes individual signals, and transmits only a data signal through the +,-data cable 208. , Only the data cable 208 is connected to the control means 205, which brings the effect of lowering the installation time and cost when wiring.

Similarly, since only the data signal is transmitted to the control means 305 by the light emitting sensor unit 303 and the light receiving sensor unit 304 in which the first and second microcomputers 303b and 304c are embedded, the light emitting sensor unit 303 And the electrical connection between the light receiving sensor unit 304 and the control means 305 is connected by a +,-data cable 308, and also the connection between the control means 305 and the home network server 310 is +,- Since it is connected by the data cable 309, the wiring work is easy and the wiring installation cost can be reduced.

For example, if the person who enters and exits is an inconvenient patient or an elderly person, and the person is alone in a specific space, a guardian who goes out when the person enters a certain space, the control means 305 and the home network server. Through 310, it is possible to check whether a cell phone is being carried, etc. At this time, if the outgoing person does not receive the exit signal even after a predetermined time elapses, it is determined that the accident has occurred to the patient or the elderly, and thus the safety accident of the patient and the elderly. Can be checked.
