 BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a monitoring system, and more particularly, to a monitoring system and a control method thereof for improving a monitoring state in a poor communication environment.

In general, a washing machine is a device in which a user puts contaminated laundry into a washing tank so that detergent and washing water are properly mixed to perform a washing process, and then complete a washing operation through a rinsing and dehydrating stroke.

In addition, the clothes dryer is a device that blows the hot air generated by the heater into the drum to absorb the moisture of the drying object and to dry the drying object.

However, in Korea, such a washing machine and a dryer are often installed and operated indoors, but in other countries such as Europe, South America, and the United States, the washing machine and dryer may be installed in a separate place such as an external warehouse or an underground laundry room. many.

This is because foreigners enjoy a lot of housing life in large space, not apartment life like Korea.

Recently, research is being actively conducted to connect household appliances to the Internet environment so that operation can be controlled remotely whenever the operation is needed, so that various household chores can be easily performed without being constrained in space and time. have.

In particular, development has been made for application to a product that takes a relatively long time in performing one operation such as a washing machine and a dryer. However, a conventional washing machine does not perform the operation and automatically operates when a certain time elapses. Considering the fact that the power is cut off and the power consumption is minimized, that is, when the washing machine is cut off, the remote control cannot be achieved.

When such remote control and monitoring through the Internet is to be performed, there is a problem that the PC, which can monitor this, must be kept on, and the manufacturing cost is increased by configuring a home network.

In addition, when the washing machine and the dryer are not installed in the house but installed in an outside warehouse or the basement, it is difficult to set up the network environment as described above. Go to the place where you have installed the laundry and input the operation command, and after inputting the operation command to determine the operation status from time to time to visit the installation site to determine the operation status.

In addition, since an error state or the like generated during the operation cannot be grasped, even though the operation is stopped due to an error generated during the washing or drying stroke, the user may not recognize this and maintain the state.

In addition, in order to input an operation command, it was possible only by moving to a place where a washing machine or a dryer is installed, causing inconvenience to the user.

Therefore, in order to solve this inconvenience, the monitoring device 10 is installed in the house to grasp the operating state of the washing machine 20 and the dryer 30 installed outside as shown in FIG. 1.

However, in the conventional monitoring device, only the state of the washing machine is displayed if the user selects the product to be monitored, that is, the user selects the washing machine, and only the state of the dryer is selected.

As described above, in order to monitor the operating states of the washing machine 20 and the dryer 30 through the monitoring device 10, quantum communication should be basically performed. The following is described with reference to FIG.

That is, a desired command is transmitted to the washing machine 20 or the dryer 30 through the monitoring device 10 (S11).

In addition, it is determined whether the response signal according to the transmitted command is a response signal from the washing machine 20 or the dryer 30 (S12).

Subsequently, the determination result (S12), the response signal is terminated, and if the response signal is not received, the packet number (N) is increased by one (S13), and the increased packet number (N) is a preset number (number_N) (S14). If the packet number N is increased by the preset number number N, the process ends.

As described above, the monitoring system and the control method according to the present invention confirm that the response comes while increasing the packet number N by a predetermined number number_N when there is no response signal after transmitting a command from the monitoring apparatus. For the same packet number (N), it is difficult to determine a case in which the signal transmission is not made correctly because it is a method of confirming a response immediately after transmitting a command once.

The present invention has been made to solve the above problems, and an object thereof is to enable the monitoring apparatus to repeatedly transmit the same command depending on whether or not a response signal is received.

In addition, there is another purpose to increase the communication success rate by controlling the command transmission in accordance with the degree of response.

It is characterized by including a memory for storing the.

More preferably, the microcomputer is characterized in that the command transmission is stopped if there is a response while repeatedly transmitting the command.

More preferably, the microcomputer does not increase the packet number while the command is repeatedly transmitted.

A control method of a monitoring system according to the present invention for achieving the above object is a control method of a monitoring system having a monitoring module for monitoring the operating state of a washing machine and a dryer, the command from the monitoring module to the washing machine and dryer And transmitting the repetitive transmission of the transmitted command and increasing the packet number according to whether there is a response signal corresponding to the command transmitted from the corresponding device. .

Preferably, the controlling of the communication may include determining whether a response signal exists from the corresponding device, repeatedly transmitting a command for a preset number of times when the response signal does not exist, and setting the number of preset times. It is characterized by including a step of increasing the packet number if exceeded, and retransmitting the command depending on whether the increased packet number is greater than or equal to the predetermined number.

More preferably, retransmitting the command further includes retransmitting the command if the increased packet number is less than or equal to a preset setting number, and terminating if the increased packet number is greater than a preset set number. It has its features.

As illustrated in FIG. 3, the monitoring system according to the present invention includes a first and a first module including a communication module for identifying an operation state according to a user's request and controlling a corresponding operation according to a command for transmitting and receiving monitoring information. 2 Home appliances 200 and 300, and transmits a predetermined command for monitoring the first and second home appliances 200, 300 to the device, and according to the degree of response received from the device Control so that the command can be repeatedly transmitted, and is configured with a monitoring module 100 for displaying the monitoring information according to the response. In this case, the first home appliance 200 and the second home appliance 300 may be configured as a washing machine or a dryer.

Here, the monitoring module 100 transmits a desired command to the first key input unit 101 and the first or second home appliance 200, 300 for inputting a product operation command desired by the user, and transmitted. A microcomputer 103 for checking whether or not the response according to the command is repeatedly output, and a communication module 104 for communicating with the home appliance according to a control signal of the microcomputer 103; A first display unit 105 for displaying the operating state of the first and second home appliances 200 and 300 according to the control signal of the microcomputer 103, and the first and second home appliances 200 The first memory 107 for storing various control-related commands of the 300 and the alarm sound generating unit 106 for notifying the uncontrollable state according to the monitoring results of the first and second home appliances 200 and 300. ), And a power supply unit 102 for supplying power.

In addition, the second home appliance 200 includes a second communication module 201 for communicating with the first communication module 104 of the monitoring module 100 and a second key input unit for inputting the user request command. 202 and a control signal for outputting a control signal according to a user request command input through the key input unit 202, and a current operation according to a monitoring command input through the first communication module 201. A second microcomputer 203 for controlling a state or the like to be transmitted to the communication unit 104 of the monitoring module 100 and a first load driver for driving a load according to a control signal of the second microcomputer 203 ( 204, a second display unit 205 for displaying an operation state, etc. according to the control signal of the second microcomputer 203, and a second memory 206 for storing the operation-related menus. .

The third home appliance 300 may include a second communication module 301 for communicating with the communication unit 104 of the monitoring module 100, a third key input unit 302 for inputting a user request command, and the like. And outputting a control signal so that a control operation can be performed according to a user request command input through the third key input unit 302, and performing a corresponding operation according to a command input through the second communication module 301. And a third microcomputer 303 for controlling the response signal to the command to be transmitted, a second load driver 304 for driving a load according to the control signal of the third microcomputer 303, and the third microcomputer. A third display unit 305 for displaying an operation state or the like according to the control signal of 303, and a third memory 306 for storing the operation-related menus.

In this case, the first communication module 104 and the second and third communication modules 201 and 301 perform power line communication or high frequency RF communication.

That is, the monitoring module 100 displays the operation state of the product selected by the user through the first key input unit 101, that is, the product selected from the washing machine or the dryer, through the first display unit 105 and simultaneously monitors the operation. To perform.

First, when a command is transmitted from the monitoring module 100, the first home appliance 200 and the second home appliance 300 transmits a response signal according to the command to the monitoring module 100, the response signal The monitoring module 100 determines whether to retransmit the corresponding command according to the presence of.

Therefore, if the response signal does not exist after the command transmission, the monitoring module 100 resends the same command by the preset number of times (number_n), and the response signal exists even though the command is resent by the preset number of times (number_n). Otherwise, the packet number N is increased.

That is, the packet number N is increased by 1, and when the increased packet number N exceeds the preset setting number number_N, the process is terminated. When the packet number N does not exceed the preset setting number number_N, the command is repeated. send. In addition, the monitoring information according to the transmitted command is displayed on the first display unit 105.

The control method of the monitoring system according to the present invention configured as described above will be described with reference to FIG. 4. First, a desired command is transmitted from the monitoring module (S101).

Then, it is determined whether there is a response signal according to the transmitted command (S102).

As a result of the determination (S102), if the response signal is present, it is terminated. If the response signal does not exist, it is determined whether the command transmission frequency (n) exceeds the preset number (number_n) (S103).

Subsequently, when the determination result (S103), the command transmission frequency (n) has not exceeded the predetermined number of times (number_n), returns to the step (S101) and retransmits the command, if the predetermined number of times (number_n) is exceeded, the packet The number N is increased by one (S104).

In operation S105, it is determined whether the increased packet number N has exceeded a predetermined setting number number_N.

As a result of the determination (S105), if the increased packet number N does not exceed the preset setting number number_N, the process returns to step S101 to retransmit the command, and the preset setting number (number_N). If exceeded, exit.
For example, the initial value of the command transmission frequency (n) is 0, the initial value of the packet number (N) is 1, the preset setting number (number_n) is 2, and the preset setting number (number_N). Can be assumed to be 2. The case where there is no response signal in the entire control process will be described.
In this case, when the packet number N is 1, three command transmissions are made. When three command transmissions are made, the number of command transmissions n exceeds the preset number of times number_n, so that the packet number N is increased to two.
When the packet number N is 2, the same command is transmitted three times. Similarly, after three command transmissions, the packet number N is increased to three.

Since the packet number N exceeds the preset setting number number_N, the packet number N ends.
As described above, the monitoring system and its control method according to the present invention increase the number of command transmissions n by the same packet number N for one command transmission when a command is transmitted from a monitoring device to a home appliance such as a washing machine or a dryer. To send the same command repeatedly. Therefore, if a response is received during command transmission, the routine is terminated. If no response is received, the command retransmission is repeated while increasing the packet number N.

As described above, the monitoring system and its control method according to the present invention have the following effects.

First, since the monitoring module can retransmit the command repeatedly depending on whether or not it responds to the command transmission, the accuracy of the command transmission can be improved.

Second, since the response signal according to the command transmission can be confirmed more times, the communication success rate can be improved even if the communication environment is not good.

Third, since the command transmission and response can be confirmed more accurately, consumers can obtain more accurate product information.
