Problems solved by technology

If there are multiple target devices in the current scene, the control of a single target device will cause the remote control to control multiple target devices at the same time. Such a control method contrary to the operator's intention will affect the usability of the target device

Embodiment 1

[0046] The invention provides a method for generating non-fixed address codes, which is used to match target devices according to the obtained address codes, such as figure 1 As shown, the generation method includes:

[0047] 11. Operate the remote control in working condition;

[0048] 12. If the operation triggers a preset operation condition, acquire the state parameters of the remote controller when the preset condition is triggered;

[0049] 13. Generate a random address code corresponding to the remote controller according to the state parameter.

[0050] In implementation, the target device is mentioned in the above steps, and the target device in this embodiment refers to a series of household appliances including the warm water toilet seat device mentioned in the background art. Due to design reasons, there is only one address code for the remote controller or target device, and multiple remote controllers must be used to remotely control multiple target devices, wh...

Embodiment 2

[0087] In Embodiment 1, a method for generating non-fixed address codes based on state parameters has been proposed. In the specific explanations 131 and 1311 of step 13, the generation method of random address codes is given. In the sending process, the command length is limited, especially the random address code obtained by constructing the sequence in step 1311 has the defect that the data length is too long. The different generation methods are:

[0088] The generation method, such as figure 2 shown, also includes:

[0089] 132. Construct a base conversion table corresponding to the value in the state parameter.

[0090] In implementation, the base conversion table can be based on the existing hexadecimal or higher-level conversion method. After obtaining the too long random address code, it can be converted with reference to the base conversion table to obtain a relatively shorter data length. The random address code, and then use the converted random address code to...

Embodiment 3

[0105] In the first two embodiments, two implementations of obtaining random address codes by processing the state parameters based on the state parameters and combining with the base conversion table are provided respectively. For the purpose of further improving the randomness of the address code, this embodiment proposes another non-fixed address code generation method, specifically:

[0106] Optionally, the preset operating conditions proposed in step 12 include:

[0107] Set parameter expectations for the target device.

[0108] In an implementation, the preset operating conditions to be triggered mentioned in step 12 include expected values ​​of parameters set for the target device. Considering that the size of the remote control to control the target device is getting smaller and smaller, and there are fewer and fewer physical buttons, it is no longer possible to perform pairing on a smaller remote control or even on a mobile device through a touch screen operation acc...

Abstract

The invention provides a method for generating a non-fixed address code, which belongs to the field of encoding and comprises the following steps: operating a remote controller in a working state; ifthe operation triggers a preset operation condition, obtaining a state parameter of the remote controller when the preset condition is triggered; and generating a random address code corresponding tothe remote controller according to the state parameter. Different address codes with randomness are generated in real time through the current state of the remote controller; a pairing process with atarget device is completed by means of the address code; the mode of storing a preset number of address codes in advance in the prior art is abandoned, the upper limit of the number of target hosts capable of being paired with the remote controller is increased, and the probability that the availability of the target device is reduced due to unavailable pairing is reduced.

Description

technical field [0001] The invention belongs to the field of encoding, in particular to a method for generating non-fixed address codes. Background technique [0002] With the development of technology, target devices including warm water toilet seat devices have begun to gradually enter families and become important household equipment. Recently, manufacturers have launched versions with remote controls for target devices, so as to improve the convenience of using the target device through wireless and remote control. [0003] Due to the limitation of remote control communication technology, the communication between the remote control and the target device can only be carried out normally after the "code pairing" operation is completed. The code pairing operation here is the process of informing the target device of the address code information of the remote controller in advance, so that the target device only sends a communication request with the remote controller corr...
