Based on the above, the invention provides an electric appliance, a wireless transfer device thereof and a control method.
An electric appliance, a wireless relay device thereof, and a control method thereof according to an embodiment of the present invention are described below with reference to the accompanying drawings.
Fig. 1 is a block diagram of a wireless relay device according to an embodiment of the present invention. As shown in fig. 1, the wireless relay device 100 according to the embodiment of the present invention includes a first transceiver 101 and a controller 102.
The first transceiver 101 is connected to the network access point 200 and at least one second transceiver 301 disposed inside the electrical device 300, and the controller 102 is connected to the first transceiver 101.
Further, the controller 102 is configured to control the first transceiver 101 to exchange data with the network access point 200 through the first frequency, and control the first transceiver 101 to exchange data with the second transceiver 301 through the second frequency.
That is to say, the wireless relay device 100 in the embodiment of the present invention can enable the first transceiver 101 and the second transceiver 301 to use the second frequency different from the first frequency for the communication between the first transceiver 101 and the network access point 200, so that when the wifi signal of the first frequency is interfered, the wireless relay device 100 can bypass the first frequency and use the second frequency for the communication with the electrical equipment, that is, the wireless relay device divides the communication between the network access point and the electrical equipment into the communication between the network access point and the first transceiver and the communication between the first transceiver and the second transceiver, so that the communication between the network access point and the electrical equipment can be achieved by combining the first frequency and the second frequency, and the communication fault caused by the interference of the first frequency is effectively avoided.
In accordance with an embodiment of the present invention, when the network access point 200 communicates with an appliance 300, the controller 102 is further configured to: acquiring a transfer frequency list of the current area and the working frequency of the current electrical equipment 300, detecting and identifying the frequency with the minimum interference from the working frequency in the transfer frequency list, and taking the minimum frequency as the second frequency.
That is to say, the controller 102 may first obtain a frequency list of frequencies available for transferring frequencies in the current region, then obtain the working frequency of the current household appliance 300 in real time, then sort the frequencies in the transfer frequency list according to the degree of interference with the working frequency, and select the frequency with the minimum interference as the second frequency, thereby effectively reducing the interference to the communication frequency when the household appliance is in the working state, and ensuring the data interaction between the second transceiver 301 and the first transceiver 101.
It should be understood that, in the embodiment of the present invention, the controller 102 may obtain the frequency list of the available and transit frequencies in the current region by querying the laws and regulations in the current region, and since the operating frequency of the specific electrical equipment does not substantially change, it may detect in advance which frequencies are affected, so as to select a frequency with relatively small influence from the selectable frequency list as the transit frequency.
In the embodiment of the present invention, the electric device 300 may include a household appliance, such as a microwave oven, and may further include a medical device or an industrial control device.
According to another embodiment of the present invention, when the network access point 200 communicates with a plurality of electric devices 300, the controller 102 is further configured to: the method comprises the steps of obtaining a transfer frequency list of a current region and the working frequency of at least one current electric appliance 300, detecting and identifying the frequency with the minimum interference of the working frequency of the household appliance in the transfer frequency list aiming at each electric appliance 300, and using the minimum frequency as a second frequency for data interaction between a first transceiver 101 and a second transceiver 301 arranged in the electric appliance 300.
For example, when there are three electrical apparatuses 300 in the system, the controller 102 obtains a relay frequency list of a current region and current operating frequencies of the three electrical apparatuses 300, for a first electrical apparatus 300-1, the controller 102 searches, in the relay frequency list, a frequency with minimum interference from the operating frequency of the first electrical apparatus 300-1 as a second frequency f-1 for data interaction between the first electrical apparatus 300-1 and the first transceiver 101, and similarly, for a second electrical apparatus 300-2, the controller 102 also searches, in the relay frequency list, a frequency with minimum interference from the operating frequency of the second electrical apparatus 300-2 as a second frequency f-2 for data interaction between the second electrical apparatus 300-2 and the first transceiver 101, and similarly, for a third electrical apparatus 300-3, the controller 102 further searches the transfer frequency list for a frequency with the minimum interference from the operating frequency of the third electrical device 300-3 as the second frequency f-3 for data interaction between the third electrical device 300-3 and the first transceiver 101.
Further, the controller 102 may adjust the operating frequency of the first transceiver 101 to f-1 when the first transceiver 101 communicates with the first appliance 300-1, adjust the operating frequency of the first transceiver 101 to f-2 when the first transceiver 101 communicates with the second appliance 300-2, and adjust the operating frequency of the first transceiver 101 to f-3 when the first transceiver 101 communicates with the third appliance 300-3.
Therefore, the wireless transfer device can minimize the interference of the working frequency of the second frequency power receiving equipment for data interaction between the first transceiver and the electrical equipment according to the working frequency of the current electrical equipment, and can realize modulation of different second frequencies according to different electrical equipment so as to meet application scenes of multiple electrical equipment and further improve the practicability of the wireless transfer device.
It should be noted that the transit frequency list in the continental china may include: 5.8Ghz, 433Mhz, 915Mhz, etc. It should be understood that the transit frequency list may be preset in the controller, and may also be obtained through the network via the network access point 200.
Further, as shown in fig. 2, the wireless relay device 100 further includes a frequency adjusting module 103, and the frequency adjusting module 103 is connected to the controller 102 for adjusting the operating frequency of the first transceiver 101 to the second frequency.
That is, after detecting and identifying the second frequency between the first transceiver 101 and the second transceiver 301, the controller 102 may control the frequency adjustment module 103 to adjust the operating frequency of the first transceiver 101 to the second frequency.
Further, the controller 102 is further configured to: the controller 102 detects and identifies that the first transceiver 101 is in a first state of receiving information sent by the network access point 200, and controls the frequency adjusting module 103 to adjust the working frequency of the first transceiver 101 to a first frequency; the controller 102 detects and identifies that the first transceiver 101 is in a second state of transmitting information to the second transceiver 301, and controls the frequency adjusting module 103 to adjust the working frequency of the first transceiver 101 to a second frequency; the controller 102 detects and identifies that the first transceiver 101 is in a third state of receiving information sent by the second transceiver 301, and controls the frequency adjusting module 103 to adjust the working frequency of the first transceiver 101 to a second frequency; the controller 102 detects and recognizes that the first transceiver 101 is in the fourth state for sending information to the network access point 200, and controls the frequency adjustment module 103 to adjust the operating frequency of the first transceiver 101 to the first frequency.
Specifically, the controller 102 detects a current communication state of the first transceiver 101 in real time, and when the network access point 200 transmits information to the electrical appliance 300, if it is recognized that the first transceiver 101 is in a first state of receiving information transmitted by the network access point 200, the controller controls the frequency adjustment module 103 to adjust the operating frequency of the first transceiver 101 to a first frequency, and if it is recognized that the first transceiver 101 is in a second state of transmitting information to the second transceiver 301, the controller controls the frequency adjustment module 103 to adjust the operating frequency of the first transceiver 101 to a second frequency.
Similarly, when the electrical apparatus 300 sends information to the network access point 200, if it is recognized that the first transceiver 101 is in the third state of receiving information sent by the second transceiver 301, the frequency adjustment module 103 is controlled to adjust the operating frequency of the first transceiver 101 to the second frequency, and if it is recognized that the first transceiver 101 is in the fourth state of sending information to the network access point 200, the frequency adjustment module 103 is controlled to adjust the operating frequency of the first transceiver 101 to the first frequency.
In other words, when the network access point 200 transmits information to the electric appliance 300, the first transceiver 101 first receives information transmitted by the network access point 200 through the first frequency, and then transmits the received information to the second transceiver 301 through the second frequency, and when the electric appliance 300 transmits information to the network access point 200, the first transceiver 101 first receives information transmitted by the second transceiver 301 through the second frequency, and then transmits the information to the network access point 200 through the second frequency.
That is to say, in the process of data interaction between the network access point 200 and the electrical appliance 300, the wireless relay device 100 divides the process into two parts, which are respectively implemented by the first frequency and the second frequency, and in the process of data transmission, if information is sent from the network access point 200 to the electrical appliance 300, the operating frequency of the first transceiver 101 is in a state of first frequency and then second frequency, and if information is sent from the electrical appliance 300 to the network access point 200, the operating frequency of the first transceiver 101 is in a state of first frequency and then first frequency.
Therefore, the wireless transfer device provided by the embodiment of the invention can adjust the working frequency of the first transceiver in real time according to the data transmission direction so as to meet the communication requirement between the network access point and the electric appliance equipment.
According to an embodiment of the present invention, as shown in fig. 2, the wireless relay apparatus 100 further includes: and the two ends of the connecting line 104 are respectively connected with the first transceiver 101 and the second transceiver 301, and the first transceiver 101 and the second transceiver 301 are paired through the connecting line 104.
That is to say, in the embodiment of the present invention, a connection line may be connected between the first transceiver 101 and the second transceiver 301, the first transceiver 101 may transmit a physical address, a password, and the like to the second transceiver 301 through the connection line 104 to implement pairing, or the second transceiver 301 may transmit a physical address, a password, and the like to the first transceiver 101 through the connection line 104 to implement pairing, thereby avoiding errors and time generated in a wireless pairing process, and further improving communication capability between the first transceiver and the second transceiver.
It should be noted that, a control panel may be further disposed in the electrical apparatus 300, and the control panel may have a pairing function, and when the user triggers the pairing function of the control panel, the second transceiver 301 knows the current pairing information and performs pairing with the first transceiver 101 again.
Further, the length of the connection line 104 can be adjusted according to actual conditions, so that the interference of the operating frequency of the electrical device 300 to the second frequency can be reduced by increasing the distance between the first transceiver 101 and the second transceiver 301.
Further, the wireless relay device 100 may be disposed in a power plug of the electrical apparatus 300.
Therefore, by arranging the wireless relay device 100 in the power plug of the electrical equipment 300, it is not necessary to additionally arrange a device on the structural appearance of the electrical equipment 300, the appearance of the electrical equipment is not affected, and the perception of the user on the wireless relay device is reduced, that is, only data interaction between the network access point and the electrical equipment exists in the perception of the user.
It should be understood that, in the embodiment of the present invention, the network access point may be a wifi transmitting end, an AP (wireless access point), or the like. Further, the second transceiver 301 disposed in the electrical apparatus 300 is generally connected to the control panel of the electrical apparatus 300, so as to send the control information to the control panel after receiving the control information sent by the network access point 200, and the control panel controls the electrical apparatus 300 according to the received information, and sends the control information to a user (a mobile terminal of the user bound to the electrical apparatus 300, etc.) through the second transceiver 301 and the network access point 200, thereby implementing the control of the user on the electrical apparatus through a wireless network.
In summary, the wireless relay device according to the embodiment of the present invention can control the controller to control the first transceiver to perform data exchange with the network access point through the first frequency, and control the first transceiver to perform data interaction with the second transceiver through the second frequency, so that a signal transmission failure caused by interference to the first frequency when the electrical equipment works can be avoided, and data communication between the network access point and the electrical equipment is ensured.
