While the invention is susceptible to various modifications and alternative forms, specific embodiments thereof are shown by way of example in the drawings and will herein be described in detail. It is to be understood, however, that the invention is not to be limited to the specific embodiments, but is to be understood to cover all modifications, equivalents, and alternatives falling within the spirit and scope of the invention, And the scope of the present invention is not limited to the following examples.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings, wherein like or corresponding elements are denoted by the same reference numerals, and redundant explanations thereof will be omitted.

FIG. 1 and FIG. 2 are a first schematic diagram and a second schematic diagram showing a direction sensor according to the present invention, respectively.

Referring to FIGS. 1 and 2, the present invention may include a direction sensor main body 10, a first sensor 11, a second sensor 12, and a control unit 13.

The first sensor 11 and the second sensor 12 may be provided on the direction sensing body 10 such that the first sensor 11 and the second sensor 12 are horizontally aligned along the entrance and exit lines so as to detect the traveling direction of the passengers. The first sensor 12 and the second sensor 12 may be provided as infrared sensors and sense a movement of a passenger in an area divided into a first sensing area A and a second sensing area B, respectively.

It is preferable that the first sensing area A and the second sensing area B are formed so as not to overlap with each other, but to be spaced apart from each other at an interval which is smaller than the width of the body or the interface.

Referring to FIG. 3, the control unit 13 determines whether to advance or not, according to the movement of the passengers sensed by the first sensor 11 and the second sensor 12.

For example, as shown in FIG. 1, if the traveling direction of the passer passes sequentially through the first sensing area A and the second sensing area B, the first sensor 11 and the second sensor 12 sequentially And transmits a signal to the control unit 13. The control unit 13 determines that the passenger enters the room and can apply power to the power supply unit in the room.

Conversely, if the traveling direction of the passer passes sequentially through the first sensing area A through the second sensing area B as shown in FIG. 2, the first sensor 11 and the second sensor 12 sequentially And transmits a signal to the control unit 13. The control unit 13 determines that the passenger has entered the room and can cut off power to the power supply unit in the room.

At this time, the controller 13 may include an internal memory 13a for storing the order and the number of signals input from the first sensor 11 and the second sensor 12.

FIG. 4 is a flowchart showing an operation method of a direction sensor according to the present invention, and FIG. 5 is a flowchart.

Referring to FIG. 4, the present invention includes a first area sensing step S1, a second area sensing step S2, an operation direction determination step S3, a power source control step S4, .

The first area sensing step S1 and the second area sensing step S2 are steps of sensing an operation that occurs when a passenger enters or exits the entrance 2 equipped with the direction sensor 10 . The passer must pass the first area A and the second area B in a specific order when passing through the access road 2. For example, when entering the entrance / exit path (2), the light passes through the first area (A) and then the second area (B).

When the first sensor 11 and the second sensor 12 sequentially detect the operation and transmit a signal to the control unit 13 through the two regions as described above, Determine the entrance and exit status of the passengers according to the order.

If the operation is detected only by either the first sensor 11 or the second sensor 12 and the operation is not detected by both of the two sensors, it is determined that the passer does not pass through the doorway 2, The malfunction can be prevented.

In the operation direction determination step S3, when the first sensing area A is detected and the second sensing area B is sensed, the controller 13 determines that the entrance has entered the entrance 2, on (on) the power source in response to a control step (S4) and, after the first recording and the circuit-on (on) that perform operations (m) the power in accordance with the operation personnel out step (S5).

If another passenger enters the entrance 2 again while the previous passenger is indoors, the above operation is performed again and the operation m is recorded twice.

Meanwhile, if a passenger in the room leaves the room through the doorway 2, the operation direction determination step S3 is performed through the first sensing area sensing step S1 and the second sensing area sensing step S2. At this time, if it is determined that the second sensing area B is sensed prior to the first sensing area A, the advancing number n is counted and recorded one time.

Since the number of operations m is twice, the number n of advancing operations is once, and m> n, the power is controlled to be kept on so that the sensor 10 operates It is possible to prevent a malfunction in which the indoor power is cut off. As described above, in the entering party calculation step (S5), the power source operation is controlled by counting the operation of entering the room and the advancing operation.

The counting of the above-mentioned personnel may be stored in the internal memory 13a in the control unit 13 and applied during the calculation.

Although the present invention has been described with reference to the accompanying drawings, it is to be understood that various changes and modifications may be made without departing from the spirit of the invention. Therefore, the scope of the present invention should not be limited to the described embodiments, but should be determined by the equivalents of the claims, as well as the following claims.
