When the load 30 is a bidet having a heating function installed in a toilet, the detection result of the human body sensor 10 maintains the warm state through the power saving mode without stopping the operation when the person is not in the room .

In addition, the operation status display unit 200 displays automatic, manual, and crime prevention statuses. When the human body sensor 10 senses that the human body sensor 10 is reattached to the connected load 30, it is automatically turned on and off automatically when the human body is recharged. Means to display.

The apparatus may further include a brightness controller 500 for adjusting brightness when the load is a light.

Hereinafter, a switch having a power saving function according to the present invention will be described in detail with reference to FIGS. 1 to 7. FIG.

The present invention further includes a communication unit to transmit the operation state of the load 30 in real time to the integrated energy management system 20 and communicate with the integrated energy management system 20 so that the user can load the load 30 Can be confirmed.

In addition, the present invention can further include a failure diagnosis unit to perform a failure diagnosis. More specifically, when the user performs a fault diagnosis on the smartphone, the fault diagnosis unit gives an on-off signal to the connected load 30 to check whether it is operating normally, and notifies the result.

Hereinafter, a latch type relay applicable to the present invention will be described in detail.

A relay is an electric part using an electromagnet. When a current is supplied to a coil, the contact is attached. When the current is cut off, the contact is dropped. A relay is a relay that is stuck even if the coil is cut off current. The relay uses a permanent magnet instead of an electromagnet and uses two coils (Set coil and Reset coil) for one relay.

The operation of the latching relay will be described in detail. Since the set coil has a smaller resistance than the reset coil and a large current flows in the set coil, the magnetic coil is set to the set state because the set coil is stronger.

Therefore, even if the excitation current is cut off, there is an advantage that the contact point is attached. Therefore, the power consumption of the load can be reduced, and even when the power is turned on while the device is turned on, it maintains its original state when the electricity returns.

4A to 4C, a control unit 600 for controlling a switch having a power saving function according to the present invention will be described in detail.

The control unit 600 is connected to the electric wire 1 connecting the switch and the load 30 to cut off or connect the electric power to the switch, to detect the amount of power used by controlling the electric power use detecting unit 400, A display unit 100, an operation state display unit 200, an on / off operation unit 300, a power use detection unit 400, a brightness control unit 500, and a circuit in which a normal microcomputer 610 for controlling the communication unit is installed .

The control unit 600 connects a flow of electric power flowing to the load 30 through the switch along the electric wire 1 when an operation signal transmitted from the energy integrated management system 20 is sensed through the communication unit, If it is not detected, the power flowing to the load 30 is cut off. The control unit causes the load 30 to display an on-off state of the load 30 through the on-off display unit 100 when the load 30 is operated, Automatic, semi-automatic, manual, crime prevention). Likewise, in the case of using a lamp, the brightness of the lamp can be controlled by controlling the brightness controller 500.

The user can remotely control the switch having the power saving function according to the present invention through the smart phone. When the switch is turned on, the microcomputer 610 of the control unit 600 detects the ON state of the selection switch The control unit 600 controls the flow of the electric power flowing to the load 30 to be directly connected to the load 30 so that the operation of the energy integrated management system 20 can be performed without regard to whether or not the operation signal transmitted from the energy integration management system 20 is sensed The flow of electric power directed to the battery 30 is always connected.

That is, in the case of the refrigerator in which the load 30 is always operated, when the user directly presses the switch or operates the smart phone in the ON state, the lamp of the on-off display unit 100 is turned on by the control unit 600, OFF state, the lamp of the on-off display unit 100 is turned off and the user can check the amount of the current detected by the power usage detecting unit 400 in real time.

Through the on-off display unit 100, the user can easily confirm the operation state and the amount of power consumed by the power usage detection unit 400 through the smartphone, thereby easily checking whether the rated current amount allocated to the outlet exceeds In addition, there is an effect that the user can induce the use of the electronic device having the rated current amount allocated to the outlet, thereby saving energy and preventing a fire caused by a short circuit.

In addition, reliability of data is important in the communication between the switch having a power saving function and each sensor and the integrated energy management system 20 according to the present invention. Particularly, a communication error in wireless communication causes a malfunction of the system, Failure to do so may result in personal injury or property damage.

Techniques for detecting and correcting errors in data communication have been conventionally used, such as CRC and turbo code. In the present system, however, a two-dimensional forward error correction method is used to correct errors in data communication.

In order to provide a multimedia service having a real time transmission characteristic in a wireless communication network environment in which a lot of packet errors such as a wireless mobile communication system occur, it is suitable to overcome the error on the wireless communication network and to improve the service quality. The two-dimensional forward error correction method is a method of aligning data packets to be transmitted in a predetermined two-dimensional block unit at the time of transmission, generating a parity packet in the horizontal direction and a parity packet in the vertical direction with respect to each row and column of the aligned packet block And recovering the lost data packet using horizontal and vertical parity packets transmitted together with the data packets when a loss of the received data packet occurs at the time of reception.

6 is a diagram conceptually showing a two-dimensional forward error correction method applicable to a switch having a power saving function according to the present invention and a transmission data encoder of a transmission side implementing a data communication method using the same.

In this figure, an RTP (Real-Time Transport Protocol) packet generation unit packetizes an input data stream into RTP packets (data packets) under the control of the control unit. The generated data packet is temporarily stored in a queue in order to generate a parity packet by the two-dimensional forward error correction method according to the present invention. The data packet stored in the queue is used to generate a parity packet by a parity packet generator. Here, the control unit controls the error recovery rate of the receiving side by using an RTCP (Real-Time Transport Control Protocol) packet transmitted from the receiving side.

The parity packets generated by the RTP packet generation unit and the parity packets generated by the parity packet generation unit are sequentially transmitted through the output buffer after being arranged in the transmission order according to the present invention in the packet order arrangement unit.

The following will be described with reference to the encoder block diagram of Fig.

First, when a data stream to be transmitted to an encoder on the transmission side is input, the RTP packet generation unit generates an RTP packet (data packet)

At this time, the controller of the encoder can know the quality (packet loss rate) of the packet being transmitted by receiving the RTCP packet containing the feedback information from the receiver. That is, the receiving side feeds back the RTP packet (data packet) received in the RTCP packet to the transmitting side, including the number of lost packets and the delay between packets (ie, delay jitter). The RTCP packet is divided into an SR (Sender Report) packet, an RR (Receiver Report) packet, an SDES (Source Description) packet, a BYE (Bye) packet and an APP RR means packet.

For example, the controller of the encoder checks the 'fraction lost' field containing the packet loss ratio information among the fields of the received RTCP packet (i.e., the RR packet) to determine whether to process the FEC (Forward Error Correction)

Here, if the packet loss rate is 0%, it is determined not to perform FEC processing, and if not, it is determined to perform FEC processing.

If it is determined that the FEC process is not performed, the RTP packets (data packets) generated by the RTP packet generation unit under the control of the control unit are sorted in the order of generation in the packet order arrangement unit and transmitted through the output buffer. In this case, the data packet is generated with a predetermined packet size, and the header and the payload are filled. Then, the transmitting side does not need to store the generated data packet in the queue.

On the other hand, if it is determined to perform the FEC process, the controller checks the 'fraction lost' field containing the packet loss ratio information among the fields of the received RTCP packet (i.e., RR packet), and determines the FEC type to be applied.

For example, if the packet loss rate is 10% or more, the FEC of the matrix (2,2) with FEC type (1) and the FEC type (2) (3,3) if the packet loss rate is 3% ~ 5% and the FEC (4,3) if the packet loss rate is 3% ~ 5% 3) Determine the FEC of the unit. Then, an FEC parity packet is generated according to the determined FEC type. That is, under the control of the control unit, the RTP packets (data packets) generated by the RTP packet generation unit are copied and temporarily stored in the queue, and the parity packet generation unit refers to the RTP packets (data packets) Dimensional FEC parity packet. Here, if the type information of the FEC technique applied to the payload type field containing the payload type information of the parity packet is stored, the receiving side does not need a separate signaling or negotiation process, Can be identified.

Then, the generated FEC parity packets are sorted in the order of transmission in the packet ordering unit together with the RTP packets (data packets) generated by the RTP packet generating unit, and then transmitted through the output buffer

That is, when the FEC is applied, a parity packet is generated by XOR operation of a data packet for generating a parity packet according to the applied two-dimensional FEC technique. In this process, the data packets necessary for generating the parity packet are copied before being transmitted and then stored in the queue. The copied data packet stored in the queue to generate a parity packet in the two-dimensional FEC block is erased from the queue when the last parity packet is generated. Since the sequence number information of the data packets used to generate the parity packet in the mask field in the header part of the parity packet is recorded by RFC 2733, the parity packet is used to recover the lost data packet at the receiving side. You can see if it should be used.

On the other hand, when determining whether to perform FEC processing, RTCP packets are not received at the initial transmission, so a specific FEC type (for example, FEC of a matrix of (4,3) FEC type 4) is applied and the FEC type is applied And if the RTCP packet is received at the receiving side with respect to the transmitted packets, it is preferable to determine whether the FEC processing and the FEC type are performed according to the reception result.

While the present invention has been described with reference to exemplary embodiments, it is to be understood that the invention is not limited to the disclosed exemplary embodiments.
