Detailed ways

In order to make the purpose, technical solutions and advantages of this application clearer, the technical solutions in this application will be clearly and completely described below in conjunction with the drawings in this application. Obviously, the described embodiments are part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

The pairing method of the present application is described below in conjunction with Figures 1 to 2. The pairing method of the present application is executed by the first transmitter in the remote control system or the hardware and/or software therein. As shown in Figure 1, the pairing method of the present application includes:

S101. A first transmitter sends first configuration information.

S102. The first transmitter receives identification information sent by each candidate pairing object and displays the identification information; wherein the identification information is sent to the first transmitter by the candidate pairing object after receiving the first configuration information; the candidate pairing object is a second transmitter or a receiver.

S103: The first transmitter determines a target pairing object among the candidate pairing objects based on a selection operation on the displayed identification information.

S104: The first transmitter performs a task of pairing with the target pairing object.

Specifically, the first transmitter and the second transmitter are used to be set in the remote control terminal in the remote control system. The receiver is a device provided on the controlled device in the remote control system to receive the control signal sent by the first transmitter and/or the second transmitter and transmit it to the controlled device, thereby controlling the controlled device accordingly through the control signal.

The candidate pairing object is a second transmitter or receiver that meets the preset conditions, for example, it can be a transmitter or receiver that is at the same configuration frequency as the first transmitter and is in a configurable state; wherein, there can be multiple candidate pairing objects, and the number of second transmitters and the number of receivers in the multiple candidate pairing objects are not specifically limited. For example, the remote control system may include at least one transmitter and at least one receiver to achieve one-to-many (one transmitter corresponds to multiple receivers), many-to-one (multiple transmitters correspond to the same receiver) or one-to-one (one transmitter corresponds to one receiver) remote control. During the pairing process, any transmitter can be used as the first transmitter according to actual application requirements, and any transmitter other than the first transmitter can be used as the second transmitter.

The first transmitter may periodically send first configuration information based on the configured frequency point in the configuration mode. The first configuration information may include an identification information request command and is sent in the form of a message.

The candidate pairing object may receive the first configuration information sent by the first transmitter, and after receiving the first configuration information, send its own identification information to the first transmitter. The identification information may be data used to characterize the identity of the candidate pairing object, and each candidate pairing object has unique identification information, and the identification information of each candidate pairing object is different. For example, the identification information may be the serial number configured by the transmitter or receiver when it leaves the factory.

After the first transmitter receives the identification information sent by each candidate pairing object, the identification information can be displayed. For example, the identification information sent by each candidate pairing object can be displayed through the display device in the first transmitter, so that the operator can view it in real time. In addition, the operator can determine whether the second transmitter or receiver corresponding to each identification information needs to be paired with the first transmitter based on the identification information displayed by the first transmitter, and select and confirm the second transmitter and/or receiver that needs to be paired with the first transmitter. Among them, the operator can select and confirm the second transmitter and/or receiver that needs to be paired with the first transmitter through the operation interface in the display device. The operation interface can also support multi-device selection operations to realize the simultaneous selection of multiple target pairing objects, so that multiple target pairing objects can be configured at the same time, and the pairing efficiency is effectively improved.

The target pairing object is a candidate pairing object corresponding to the identification information selected based on the selection operation, that is, the second transmitter and/or receiver that needs to be paired with the first transmitter. The first transmitter determines the target pairing object according to the operator's selection operation on each displayed identification information, thereby effectively ensuring the accuracy of the determination result of the target pairing object. At the same time, the target pairing object can also be determined according to the pairing requirements in different control modes.

After determining the target pairing object, the first transmitter performs the task of pairing with the target pairing object. For example, the address code of the first transmitter and/or the target pairing object can be configured so that the address code of the first transmitter is consistent with that of the successfully configured target pairing object. In the process of configuring the address code of the first transmitter and/or the target pairing object, the first transmitter can send its own address code to each target pairing object, and each target pairing object configures its own address code according to the address code of the first transmitter; the first transmitter can also send the address code input by the operator or the address code pre-set by the system to each target pairing object, and the first transmitter and each target pairing object configure their own address code based on the address code sent by the first transmitter.

After the first transmitter is successfully paired with the target pairing object, the pairing of the remote control can be completed. After the first transmitter is successfully paired with the receiver, the controlled device with the receiver can be remotely controlled by the first transmitter; after the first transmitter is successfully paired with the second transmitter, the controlled device with the same receiver can be controlled by the first transmitter and the second transmitter. For example, different components of the controlled device can be controlled by the first transmitter and the second transmitter.

The embodiment of the present application sends the first configuration information through the first transmitter, receives and displays the identification information fed back by each candidate pairing object, and determines the target pairing object among the candidate pairing objects based on the selection operation of the displayed identification information, which can effectively ensure the accuracy of the determination result of the target pairing object, so that the task of pairing with the target pairing object is performed by the first transmitter, and the normal operation of the remote control system after pairing can be effectively guaranteed.

At the same time, in order to ensure the accuracy of pairing, the existing remote control system has two settings on the transmitter and receiver. A pairing key is set to achieve pairing when the pairing keys on the transmitter and receiver are pressed at the same time, or an ID card slot is configured on the main board of the transmitter or receiver to insert an ID card in the ID card slot and achieve pairing according to the ID card. However, setting the pairing key and the ID card slot requires changing the structure of the remote control system, and replacing the remote control system requires a high cost. The embodiment of the present application sends the first configuration information through the first transmitter, receives and displays the identification information fed back by each candidate pairing object, determines the target pairing object among each candidate pairing object based on the selection operation of the displayed identification information, and performs the task of pairing with the target pairing object through the first transmitter, without changing the structure of the remote control system, that is, accurate pairing can be achieved based on the existing structure of the remote control system, thereby avoiding the increase in cost caused by replacing the remote control system.

In addition, the embodiments of the present application can implement two modes: a transmitter configures a receiver and a transmitter configures a transmitter, so that the remote control system can be applied to different control modes, thereby expanding the scope of application of the remote control system.

Based on the above embodiment, the pairing method is performed at a preset configuration frequency point; wherein the frequency interval between the preset configuration frequency point and the working frequency band of the first transmitter is greater than or equal to the preset frequency interval.

Specifically, the preset configuration frequency point is the frequency point used by the first transmitter to transmit signals to each candidate pairing object during the pairing process of the remote control system. The frequency interval between the preset configuration frequency point and the working frequency band of the first transmitter is greater than or equal to the preset frequency interval, that is, the frequency interval between the endpoint closest to the preset configuration frequency point and the preset configuration frequency point of the two endpoints of the working frequency band of the first transmitter is greater than or equal to the preset frequency interval. The size of the preset frequency interval can be set according to actual needs, and it can avoid the signal transmitted on the preset configuration frequency point and the signal transmitted in the working frequency band from interfering with each other, thereby effectively avoiding co-frequency interference in the pairing process of the remote control system, ensuring the reliability of the signal transmitted during the pairing process, and then ensuring the validity of the pairing result. For example, the preset configuration frequency point can be set to 310 MHz, and the working frequency band of the first transmitter can be set to 430 MHz to 440 MHz.

The pairing method of the embodiment of the present application is completed at a preset configuration frequency point, and the frequency interval between the preset configuration frequency point and the working frequency band of the first transmitter is greater than or equal to the preset frequency interval, which can effectively avoid co-frequency interference and ensure the validity of the information transmitted during the pairing process, thereby effectively improving the pairing accuracy.

Based on any of the foregoing embodiments, the first transmitter sends the first configuration information, including:

Specifically, when pairing is required, the operator can input configuration instructions to the first transmitter. For example, the configuration instructions can be input through a button set on the first transmitter. When the first transmitter receives the configuration instructions, the configuration mode is turned on, the main board of the first transmitter generates first configuration information, and sends the first configuration information to the wireless board of the first transmitter through CAN framing. The wireless board of the first transmitter periodically sends the first configuration information based on a preset configuration frequency, so that the remote control system can be paired according to actual needs, thereby ensuring the validity of the pairing result of the remote control system.

Based on any of the above embodiments, the candidate pairing object sends the identification information to the first transmitter through the following steps:

Specifically, the preset state may be a configurable state, for example, a power-on initialization state. During the pairing process of the remote control system, the operator may power off and restart the corresponding second transmitter and/or receiver.

When the candidate pairing object is powered on and initialized, the first configuration information is periodically searched based on the preset configuration frequency, that is, the frequency at which the candidate pairing object searches for the first configuration information is the same as the frequency at which the first transmitter sends the first configuration information, so that the candidate pairing object can normally receive the first configuration information sent by the first transmitter. At the same time, it can effectively avoid the transmitter or receiver working or configured at other frequencies from sending identification information to the first transmitter, thereby improving the selection efficiency of the target pairing object.

The preset duration can be set according to actual needs, for example, it can be less than or equal to the duration of power-on initialization of the candidate pairing object during the restart process. If the candidate pairing object does not search for the first configuration information within the preset duration, it is configured to transmit and receive signals in the working frequency band; if the candidate pairing object searches for the first configuration information within the preset duration, it sends its own identification information to the first transmitter, thereby ensuring the validity of the pairing and avoiding affecting the normal operation of the candidate pairing object.

The identification information of the candidate pairing object is stored in a corresponding storage device. For example, a memory is provided on the main board of the candidate pairing object, and its own identification information is stored in the memory. After searching for the first configuration information, the candidate pairing object can query the identification information stored in the corresponding storage device through CAN framing and send it to the first transmitter.

In addition, the identification information of the candidate pairing object is also marked on the outside of the pairing object. For example, the identification information can be displayed on the shell of the corresponding candidate pairing object by coding or labeling, so that the operator can compare the identification information displayed on the first transmitter and the identification information displayed on the shell of the second transmitter and/or receiver to be paired during the pairing process, thereby being able to quickly and accurately determine the target pairing object, avoiding the impact of pairing errors on the normal operation of the remote control system, and reducing the probability of re-pairing after a pairing error, thereby greatly improving the pairing efficiency.

Based on any of the above embodiments, the first transmitter performs a task of pairing with the target pairing object, including:

Specifically, when the first transmitter performs the task of pairing with the target pairing object, it can send second configuration information to the target pairing object. The specific content of the second configuration information can be determined according to actual needs. For example, it can include the address code of the first transmitter. The target pairing object can configure its own address code according to the address code sent by the first transmitter.

After receiving the second configuration information sent by the first transmitter, the target pairing object can configure its own address code according to the second configuration information, and send a corresponding configuration response signal to the first transmitter according to the configuration result. For example, the configuration response signal can be sent in the form of a CAN message. The first transmitter determines the pairing result, for example, pairing success or pairing failure, by parsing the configuration response signal. In addition, the first transmitter can also display the pairing result in real time through a display device, so that the operator can check the pairing status in time.

In the embodiment of the present application, the first transmitter sends the second configuration information to the target pairing object, and receives the configuration response signal fed back by the target pairing object. When the pairing is determined to be successful based on the configuration response signal, the pairing of the first transmitter and the corresponding target pairing object is completed, thereby effectively ensuring Validity of the pairing results.

Based on any of the above embodiments, the second configuration information includes a first address code of the first transmitter, and the first address code is used for address code configuration of the target pairing object.

Specifically, when the first transmitter sends the second configuration information, the first transmitter sends its own first address code to each target pairing object. When each target pairing object receives the second configuration information, it can configure its own address code according to the first address code in the second configuration information, so that the address code of each target pairing object is consistent with the address code of the first transmitter, so that after the pairing is completed, the first transmitter and the successfully paired second transmitter can communicate normally with the successfully paired receiver.

In order to improve the ability to resist co-frequency interference, the existing remote control system sets a unique address code at the factory. Different address codes have different wireless communication frequencies. During the process of sending and receiving co-frequency wireless data, only wireless data with the same address code is processed to filter out interference data. However, since the address code is fixed before leaving the factory, if the transmitter or receiver is damaged during use, the user must replace the entire remote control system or clone the same address code through research and development, which greatly increases the cost and is inconvenient.

In the embodiment of the present application, after the target pairing object is determined, the first transmitter sends its own address code to each target pairing object, so that the target pairing object can configure its own address code according to the address code of the first transmitter, that is, after the target pairing object is configured, its address code is consistent with the address code of the first transmitter, so that the paired remote control system can communicate normally, and there is no need to solidify the address codes of the transmitter and the receiver. When replacing the transmitter or receiver, the address code can be configured by pairing, avoiding the replacement of the entire remote control system and the need to clone the address code, thereby reducing costs and being highly convenient.

Based on any of the above embodiments, the target pairing object is configured with an address code through the following steps:

Specifically, when the target paired object receives the second configuration information sent by the first transmitter, it can update its own second address code based on the first address code in the second configuration information to complete the configuration of the target paired object address code. For example, the target paired object can store the first address code and replace its own second address code with the first address code of the first transmitter to maintain The address code of each target pairing object is ensured to be consistent with the address code of the first transmitter, so that the paired remote control system can work normally and the address code can be configured quickly and accurately.

In addition, the successfully paired target pairing object can also be restarted to complete the configuration of the address code. The operator can manually control the successfully paired target pairing object to restart according to the pairing result displayed on the first transmitter; the operator can also send the third configuration information to the successfully paired target pairing object through the first transmitter, and the successfully paired target pairing object automatically restarts after receiving the third configuration information.
