Description

Remote control device for controlling the power of the device remotely. {.}

Generally, when a power failure occurs, a device that requires energy of electricity stops working. A device such as an uninterrupted power supply (UPS) is used to prevent the operation from stopping. However, since the above UPS is operated by charging the battery, it is difficult to operate for a long time, and the device operated by the UPS also operates after the capacity of the UPS has passed. Stops. In addition, the equipment such as the UPS is expensive and there are many difficulties in use. Therefore, the present invention is intended to notify the user when the power transmission after the power failure and to allow the user to quickly turn on the power of various control target devices remotely. The related art is disclosed by Korean Laid-Open Publication No. 1999-66206 (1999.08.16), but it relates to a remote power supply control circuit and method, in particular, a modem (MODEM) such as a computer, a communication system, and a LAN (RAN). The present invention relates to a circuit and a method for remotely controlling a power supply using a telephone line or a LAN port together with a system having a communication port. However, such a prior art has to be transmitted and received through a communication network, so the equipment is expensive due to the need for a modem and the like, and since the smooth operation does not occur at the time of power failure, the constant power should be supplied. In order to improve this, the present application is to detect the power outage and power transmission status to notify the user quickly and to continue the operation of the device by turning on the power of the control unit installed in the facility through the telephone line.

The present invention to solve the above-mentioned problems, the remote control device proposed in the present invention is a power monitoring unit, a key input unit for inputting a telephone number, a memory (RAM) for storing a telephone number, a voice for storing a notification message It consists of IC, dual tone multiple frequency (DTMF) transmitting / receiving unit which can transmit / receive with CO line, and power switch driving unit which drives the power switch of the control unit. In order to enable the user to continue the operation of the equipment by immediately turning on the control unit installed in the facility through the telephone line.

The present invention is to remotely control the power of the controlled device by using a telephone line to notify the user quickly when a power failure for efficient management and use of special cultivation facilities, computers, home appliances, etc. It is to make it possible.

The configuration of the present invention for this purpose is a power outage monitoring unit 201 for monitoring the power outage and key input unit 202 for inputting a phone number, voice IC 205 for storing a notification message, DTMF for converting a phone number into a dial tone sound The converting unit 206, the DTMF transmitting unit 207 for transmitting the same, the DTMF receiving unit 209, the power switch driving unit for driving the power switch of the controlled device, and the CPU 203 for controlling the above devices.

This will be described in detail with reference to the accompanying drawings.

1 shows an embodiment of the present invention, in which a device 200 for remotely turning on the device of the present invention is connected to a general telephone line, and the device to be controlled is connected to the device. In the state configured as described above, if there is a voltage change in the power monitoring unit, it determines whether there is a power outage or transmission and automatically dials to the user to send a notification message and allow the user to take a quick action. That is, a signal for turning on the power of the controller is sent so that the controller is powered.

2 is a detailed embodiment of the present invention in the power monitoring unit 201 composed of a voltage comparison unit 201-1 and a positive / power transmission discrimination unit 201-2 for monitoring the change in the current voltage voltage rises that the power failure if the voltage drops. If it is determined that the power transmission.

Voice IC 205 for storing the notification message inputted from the key input unit 202, the memory unit 204 for storing the wired and wireless telephone number and the pager number of the user, and the voice input unit 208 for inputting the notification message. And a DTMF converter 206 for converting a number stored in a memory into a dial tone, a DTMF transmitter 207 and a DTMF receiver 209, a power switch driver 210, and a CPU 203 for overall control of the above configuration. It is composed of

In order to explain this in detail, the following description will be made with reference to FIGS. 2, 3, and 4.

First, as shown in FIGS. 2 and 3, when the user inputs a telephone number capable of informing power failure and transmission status, that is, a landline telephone, a cellular telephone number, and a pager telephone number to the key input unit 202, the input key value is stored in the memory unit. Stored sequentially at 204. According to the storage order, the first telephone number inputs the number of the communication terminal most frequently used by the user, and then enters the number of other communication terminals. There may be only one number of the communication terminal to input. In addition, when the notification message according to the power failure / power transmission state is input through the voice input unit 208 which is a voice input unit, it is stored in the voice IC 205. The notification message may be input differently according to the user. For example, "00 fish farm or power off of computer. Please take immediate action." Or "00 power is on. Turn on computer."

In FIGS. 2 and 4, the power monitoring unit 201 that monitors the power failure / transmission state checks the current state (step 1). If the voltage rises, it is determined that the transmission state (step 2-2). In order to notify the user, the first telephone number stored in the memory 204 is read (step 3), and the DTMF converter 206 converts the DTMF sound (step 4) into the DTMF transmitter 207 (step 4). Step 5) Dial the user. However, if there is no voltage change in steps 2-1 and 2-2, it is fed back to the first step to check the current voltage state. After the fifth step, if the call is received because the user's terminal is connected (step 6), the voice IC 205 reads the notification message (step 8) and sends the notification message (step 9). In the sixth process, if there is no incoming signal of the user's terminal for a predetermined time, the second telephone number stored in the memory 204 is read and fed back to the fourth step.

After the ninth step, if there is a power switch driving signal from the DTMF receiver 209 (step 10), the power switch driver 210 is driven (step 11) to turn on the power of the control unit 300.

If there is no power switch drive signal from the DTMF receiver 209 in step 10, the process is terminated without driving the power switch. Another embodiment of the present invention is characterized in that the power switch between the driver 210 and the control unit 300 is performed by transmitting and receiving wirelessly through infrared. In addition, the present source is characterized by using a power source supplied from a telephone line. Therefore, the present invention works even if the power supply of the commercial power line is out of power.

The present invention is not limited to the above-described embodiments, and of course, modifications may be made by those skilled in the art without departing from the spirit of the present invention.

As described above, the present invention differs from the conventional remote power control circuit and method by inputting a telephone number or a portable telephone wireless pager number capable of calling a user, and promptly notifying the user when a power failure or power transmission is performed. It can be turned on to effectively manage and use special cultivation facilities, computers, and home appliances.

As described above, the present invention enables the user to quickly understand the current state at the time of power failure and power transmission, and to notify the power failure and power transmission status by making a call to the user's telephone and pager when the user is at a long distance. If the current state is correctly recognized and the power is transmitted in the blackout state, there is an effect that the controller can be turned on.
