judging whether the value set in the user menu or the factory menu is 0; if the client code is 0, setting the second client code as an electronic whiteboard initial client code; if not 0, the second client code is set to a value set in a user menu or a factory menu and stored in the remote control code receiving unit 201 to be paired with the first client code of the remote control code transmitting unit 102.
The method for setting the second client code by the receiving-end client code setting unit 202 further includes:
and judging whether the range of the numerical value set in the user menu or the factory menu is 0-255, and if not, prompting an error.
In one embodiment, the remote controller 10 further includes a sending-end dynamic client code setting unit 103; the remote control code sending unit 102 is connected to the sending-end dynamic client code setting unit 103 to receive the setting of the first client code.
Referring to fig. 4, the method for setting the first client code by the sender dynamic client code setting unit 103 includes:
receiving a setting request sent by the remote controller 10; the setting request is initiated by a setting key 101 on the remote controller 10;
judging whether the time of the setting request exceeds a preset value or not, and if so, receiving a first client code setting request sent by a digital key 101; and after the first client code setting request is judged, whether the setting request sent by the remote controller 10 is received or not is judged, if yes, the first client code is set as the key value of the numeric key 101 sending the request.
Specifically, in this embodiment, the external keys 101 of the remote controller 10 need not be modified, and only the "set" key 101 and the number key 101 on the existing remote controller 10 need to be used.
The preset value can be 3s, and if the time for pressing the setting key exceeds 3s, the setting of the first client code can be started; specifically, a user presses a certain number key or a combination of number keys; after the key value of the numeric key 101 is input, the setting needs to be validated by pressing the "set" key 101 again, and if the "set" key 101 is not pressed again, the setting is invalidated, and the first client code remains unchanged.
In addition, after receiving the key value input of the numeric keys, whether the key value is 0 is needed; if 0, setting the first client code as the initial client code of the remote controller 10; if not, the first client code is set as the key value of the numeric key 101 and stored in the remote control code sending unit 102, so that the second client code of the remote control code receiving unit 201 can be paired.
Specifically, a plurality of different first client codes can be provided according to the number of electronic whiteboards in an exhibition hall or a marketplace, and each first client code is paired with one electronic whiteboard.
The method for setting the first client code by the sending-end dynamic client code setting unit 103 further includes:
and judging whether the range of the key values of the number key 101 for sending the request is 0-255, and if not, prompting an error.
In another embodiment, a plurality of buttons 101 need to be newly added to the remote control, and the newly added buttons 101 include a plurality of numeric keys; the remote controller 10 further includes a sending-end static client code setting unit 104; the remote control code transmitting unit 102 is connected to the transmitting-end static client code setting unit 104 to receive the setting of the first client code.
The method for setting the first client code by the sending-end static client code setting unit 104 includes:
receiving a setting request sent by the newly added key 101; and setting the first client code as the key value of the newly added key 101 for sending the request.
Specifically, the number keys 101 may be added with a number of number keys 101 as needed, and fig. 5 shows seven number keys 101 with 01 to 07 added.
In specific implementation, any one of the seven number keys 101 can be clicked as required, so that the first client code of the remote controller 10 can be modified quickly; the mode is used for fast switching control when an exhibition hall or a sales hall comprises no more than 7 electronic white boards of the same manufacturer.
It is understood that, in the same remote controller 10, both the sender dynamic client code setting unit 103 and the sender static client code setting unit 104 may be included, and in this case, the remote controller 10 associated with the newly added key 101 is also required. When the exhibition hall or the sales hall includes more than 7 electronic whiteboards of the same manufacturer, the first client code can be set through the sending terminal dynamic client code setting unit 103, specifically, the setting key is pressed to be larger than the preset value, then the original numerical value key of the remote controller 10 is pressed to set the first client code, and finally the setting key is pressed again to realize setting. When the exhibition hall or the sales hall includes 7 electronic whiteboards of the same manufacturer or less, the first client code can be set by the static client code setting unit 104 of the sending end, and particularly, the quick setting can be realized by pressing any one of the newly added 01 to 07 number keys.
The above description is only an embodiment of the present invention, but the design concept of the present invention is not limited thereto, and any insubstantial modifications made by using the design concept should fall within the scope of infringing the present invention.
