Description

[Technical Field]

[0001] This utility model relates to an RF pairing remote control with multiple combination modes of DIP switch and rolling code learning. [Background Technology]

[0002] The remote control command codes of commercially available wireless remote controls are generally generated through DIP switch settings or pure rolling code learning. DIP switch settings generate codes by arranging and combining several DIP switch digits, resulting in a very limited number of code values; for example, a four-digit DIP switch only generates a sixteen-bit code. Meanwhile, pure rolling code learning generates a relatively small number of code values. When production reaches a certain volume, duplicate code values ​​may be generated. Therefore, such products can only be sold to different users; otherwise, duplicate code values ​​may cause remote control code conflicts, increasing inconvenience for users and causing after-sales problems.

[Image Description]

[0018] Figure 2 This is a circuit diagram of the present invention. [Detailed Implementation]

[0019] The technical solutions in the embodiments of this utility model will now be clearly and completely described in conjunction with the accompanying drawings.

[0020] It should be noted that all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of this utility model are only used to explain the relative positional relationship and movement of the components in a specific posture (as shown in the attached figure). If the specific posture changes, the directional indication will also change accordingly. Furthermore, descriptions involving "preferred," "second-best," etc., in this utility model are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, features defined as "preferred" or "second-best" may explicitly or implicitly include at least one of those features.

[0021] like Figure 1-2As shown, an RF pairing remote control with multiple combination modes of DIP switch and rolling code learning includes a DIP setting circuit 1 for setting DIP switch plus rolling code learning or pure rolling code learning modes. The learning mode DIP setting circuit 1 includes at least one DIP switch SW1 with multiple switch positions. The learning mode DIP setting circuit 1 is connected to a main control circuit 2 that enters pure rolling code learning mode to set wireless remote control command codes when all switch positions of the DIP switch SW1 have the same DIP switch value of 0, or enters DIP switch plus rolling code learning mode to set wireless remote control command codes when any switch position of the DIP switch SW1 has a DIP switch value of 1. The main control circuit 2 is connected to a button circuit 3 for inputting remote control commands to the main control circuit 2 and a transmitter circuit 4 for transmitting the corresponding wireless remote control command codes according to the remote control commands input by the button circuit 3. When setting the remote control encoding code value, the switch position of the DIP switch SW1 in the learning mode setting circuit 1 can be toggled according to actual needs, so that the main control circuit 2 enters the pure rolling code learning mode or the DIP code plus rolling code learning mode to set the wireless remote control command code. This case is compatible with both the DIP code plus rolling code learning mode and the pure rolling code learning mode, which greatly increases the number of encoding code values ​​of the wireless remote control and reduces the problem of conflict caused by the duplication of remote control command codes between different remote controls.

[0022] In this case, the main control circuit 2 enters a pure rolling code learning mode to set the wireless remote control command code when all switch positions of the DIP switch SW1 are 0, and enters a DIP plus rolling code learning mode to set the wireless remote control command code when any switch position of the DIP switch SW1 is 1. In this case, when the main control circuit 1 enters the pure rolling code learning mode, there are a total of 65,536 possible code values.

[0023] like Figure 2 As shown, the DIP switch SW1 has ten switch positions. That is, when the DIP switch SW1 is set to 0000000000, the main control circuit 1 enters the pure rolling code learning mode, and 65536 encoding code values ​​can be set.

[0024] On the other hand, when at least one of the ten switch positions of the DIP switch SW1 is set to 1, that is, when the DIP switch SW1 is set to any one of the DIP values ​​from 0000000001 to 1111111111, the main control circuit 1 enters the learning mode of DIP and rolling codes. At this time, the number of configurable code values ​​is the ten-digit DIP value multiplied by the rolling code value, which can set 67,108,864 code values. This greatly increases the number of code values ​​of the wireless remote control and reduces the problem of conflicts caused by the repetition of remote control command codes between different remote controls.

[0025] For example, if the first toggle button in the ten-position DIP switch is pressed, the subsequent DIP learning code is 0000000001 + roll code; or if the first and second toggle buttons in the ten-position DIP switch are pressed, the subsequent DIP learning code is 0000000011 + roll code.

[0026] Figure 2 As shown, the main control circuit 2 is connected to an indicator light circuit 5 for indicating the working status, a power supply circuit 6 for supplying power to the main control circuit 2 and the transmitting circuit 4, and a switch circuit 7 for controlling power on / off and testing. After triggering the switch circuit 7, the power supply battery 6 supplies power to the remote control. Subsequently, when setting the remote control code value to the main control circuit 2, the switch position of the DIP switch SW1 in the learning mode setting circuit 1 is adjusted according to actual production needs, causing the main control circuit 1 to enter either a pure rolling code learning mode or a DIP plus rolling code learning mode to set the wireless remote control command code. After setting, remote control commands can be input to the main control circuit 2 via different buttons on the trigger button circuit 3, causing the main control circuit 2 to transmit the corresponding wireless remote control command code through the transmitting circuit 4 for remote control. The indicator light circuit 5 provides the working status indicator light.

[0027] like Figure 2 As shown, during remote control learning encoding, switching the DIP switch SW1 in the learning mode setting circuit 1 sends different signals to the corresponding pins of the main control chip U1 in the main control circuit 2, causing the main control circuit 2 to enter either pure rolling code learning mode or DIP code plus rolling code learning mode, thereby setting the wireless remote control command code. In actual use, when a button on the button circuit 3 is pressed and triggered, a remote control command is sent to the corresponding pin of the main control chip U1 in the main control circuit 2. The main control chip U1 then sends the corresponding wireless remote control command code to the transmitter chip U2 in the transmitter circuit 4 according to the remote control command, causing the transmitter chip U2 to transmit the wireless remote control command code outward through the antenna ANT.
