[0029] The main solution of this application embodiment is: receiving an input first signal and identifying a first format of the first signal; converting the first signal into a second signal of a preset second format according to a preset conversion rule, wherein the first format is different from the second format; transmitting the second signal through the integrated wiring harness of the control signal transmission device; restoring the received second signal to the first signal so as to drive the load through the first signal.
[0030] In the field of lighting control, there are various methods for transmitting control signals, such as PWM (Pulse Width Modulation), serial communication, return-to-zero code, and 0 / 1-10V analog signals. These traditional control signal transmission methods have the advantages of being easy to operate and convenient to use, and have been widely used in many lighting control scenarios. However, they also have significant drawbacks, namely, relatively short transmission distances and that the control signals are easily affected by external interference, which leads to a decrease in signal quality and affects the accuracy and stability of lighting control.
[0031] To address the aforementioned issues, several solutions have been developed in this field. On one hand, increasing the signal amplitude and reducing the control signal transmission rate enhances the signal's anti-interference capability; the DALI (Digital Addressable Lighting Interface) protocol employs this approach. On the other hand, differential transmission methods, such as DMX512 differential transmission, are used to improve the reliability of control signal transmission by suppressing common-mode interference.

[0032] Therefore, how to ensure stable transmission of lighting control signals while avoiding reduced data transmission efficiency and increased system complexity has become a key issue that urgently needs to be addressed in the current field of lighting control.
[0033] To address the aforementioned issues, this application provides a control signal transmission method. Upon receiving a first signal in a first format, this application converts the first signal into a second signal in a second format that is less susceptible to interference for transmission. After transmission, the second signal is restored to the first signal, and then the load is driven by the first signal.
[0034] In summary, this application converts the first format control signal, which is susceptible to electromagnetic interference, into a second format control signal, which is less susceptible to interference, for transmission. This reduces the problem of signal quality degradation during transmission. Furthermore, the second format control signal is restored to the first format control signal before signal output, eliminating the need to modify the port protocol and reducing system complexity and cost. Thus, while ensuring stable transmission of lighting control signals, it avoids problems such as reduced data transmission efficiency and increased system complexity.
[0035] In this embodiment, for ease of description, the following description will focus on the control device as the executing entity.
[0036] Based on this, embodiments of this application provide a control signal transmission method, referring to... Figure 1 , Figure 1 This is a flowchart illustrating the first embodiment of the control signal transmission method of this application.
[0037] In this embodiment, the control signal transmission method includes steps S10 to S40: Step S10: Receive the input first signal and identify the first format of the first signal; In this embodiment, in the control signal transmission device, when an external control signal is input, the signal recognition and processing module 10 captures the signal and temporarily stores it in the internal buffer area. Then, the format recognition algorithm is called to analyze the signal in the buffer. The algorithm determines the format type of the signal by detecting specific characteristics of the signal (such as pulse width, voltage amplitude, encoding rules, etc.). After the recognition is completed, the signal format information is stored in the device memory for subsequent processing.
[0038] Furthermore, in a feasible implementation, step S10 above may include steps S11-S12: Step S11: Detect the level range and level characteristics of the first signal; In this embodiment, in the control signal transmission device, when an external control signal is input, the signal recognition and processing module 10 first activates the level detection function to sample the input signal in real time, obtain the voltage value of the signal at different times, and determine the level range of the signal, i.e. the maximum voltage value and the minimum voltage value of the signal, by analyzing the sampled data. At the same time, the level characteristics of the signal are further analyzed, including parameters such as the high level duration, low level duration, pulse width, and duty cycle of the signal.
[0039] Step S12: Determine the first format corresponding to the level range and level characteristics.
[0040] In this embodiment, after obtaining the level range and level characteristics of the first signal, the signal recognition and processing module 10 calls the format matching algorithm. The algorithm has a built-in signal format database, which contains level range and level characteristic information of various common signal formats. The format matching algorithm compares the detected level range and level characteristics with the information in the database one by one to find the most matching signal format. Once a matching signal format is found, the algorithm determines the first format of the signal.
[0041] By detecting the level range and level characteristics of the first signal, the signal format type can be identified more accurately.
[0042] Step S20: Convert the first signal into a second signal in a preset second format according to a preset conversion rule, wherein the first format is different from the second format; It should be noted that in this embodiment, the second format is a signal type that is less susceptible to interference and loss during long-distance transmission, such as an RS485 signal.
[0043] In this embodiment, based on the identified signal format, a corresponding conversion algorithm is retrieved from a preset conversion rule base. This rule base contains conversion methods between various common signal formats, such as from PWM signals to differential signals, and from serial communication signals to DALI protocol signals. After selecting a conversion algorithm, the first signal data in the buffer is read, and the format is converted according to the steps specified by the algorithm. During the conversion process, parameters such as the signal timing, amplitude, and encoding method are adjusted to generate a second signal that meets the requirements of the second format. After the conversion is complete, the second signal is stored in a new buffer area, ready for transmission.
[0044] Step S30: The second signal is transmitted through the integrated wiring harness of the control signal transmission device; In this embodiment, the generated second signal is transmitted to the control signal transmission module 20. The control signal transmission module 20 includes an integrated wire harness that integrates multiple functions such as signal transmission and power supply. Before sending the signal, the control signal transmission module 20 can perform necessary preprocessing on the second signal, such as amplifying the signal amplitude and adjusting the signal frequency, to ensure that the signal can be transmitted stably and reliably in the wire harness. After the preprocessing is completed, the control signal transmission module 20 injects the second signal into the integrated wire harness, and the signal is transmitted along the wire harness to the target load.
[0045] Step S40: The received second signal is restored to the first signal so as to drive the load through the first signal.
[0046] It should be noted that, in this embodiment, the load includes, but is not limited to, drivers, controllers, and light strips.
[0047] In this embodiment, a signal receiving and processing module 30 is also provided at the signal output end of the integrated wiring harness. After receiving the second signal, the signal receiving and processing module 30 parses and converts the second signal according to a preset restoration rule, restoring it to the original first signal format. During the restoration process, parameters such as the signal timing, amplitude, and encoding method are reverse-adjusted to restore the original characteristics of the signal. After restoration, the first signal is transmitted to the load. The load controls the switching, brightness, color, and other parameters of the lighting load according to the instructions of the first signal, thereby achieving precise control of the lighting system.
[0048] Furthermore, in a feasible implementation, step S40 above may include: steps S41~S42: Step S41: Analyze the second signal to obtain the original data; In this embodiment, at the signal output end of the integrated wiring harness, after the signal receiving and processing module 30 receives the second signal (such as an RS485 signal) after long-distance transmission, it initiates the signal parsing function. This module can first preprocess the received second signal, including filtering and noise reduction operations, to eliminate interference and noise that may be introduced during signal transmission. Subsequently, a preset parsing algorithm is invoked. This algorithm parses the signal bit by bit according to the specific encoding rules and protocol format of the second signal. For example, if the second signal uses differential encoding, the parsing algorithm will restore the differential signal to the original binary data stream according to the rules of differential encoding. During the parsing process, the algorithm will accurately identify the start bit, data bit, parity bit, and stop bit of the signal to ensure the accuracy of the parsing result. After parsing processing, the original data information is extracted from the second signal. This data information is the key instruction for controlling the lighting load.
[0049] Step S42: Encapsulate the raw data into the first format to obtain the first signal.
[0050] In this embodiment, after obtaining the raw data, the signal receiving and processing module 30 calls the corresponding encapsulation algorithm based on the previously identified and stored first signal format information. The encapsulation algorithm re-encapsulates the raw data according to the specific requirements of the first signal format, adjusting parameters such as the timing, amplitude, and encoding method of the data. For example, if the first signal is a PWM signal, the encapsulation algorithm will convert the raw data into a corresponding PWM pulse sequence according to the pulse width modulation rules of the PWM signal. During the encapsulation process, the algorithm strictly follows the protocol standard of the first signal format to ensure that the encapsulated signal meets the format requirements that the target device can recognize. After encapsulation, a first signal with the same format as the original input signal is obtained, which contains complete instruction information for controlling the lighting load.
[0051] In this application, by converting a first-format signal, which is susceptible to electromagnetic interference, into a second-format signal, which is less susceptible to interference, the risk of external interference during signal transmission is effectively reduced, and the transmission quality and stability of the signal are improved. Before signal output, the second-format signal is restored to the original first-format signal, so that the target device does not need to perform protocol conversion or interface circuit modification, reducing the complexity and cost of the system. At the same time, the use of standardized signal format and transmission method facilitates system maintenance and upgrades. Furthermore, this solution supports the conversion and transmission between multiple signal formats, enabling the system to flexibly adapt to different lighting control needs and equipment types. In addition, the use of a universal integrated wiring harness for signal transmission improves the system's compatibility and scalability.
[0052] It should be noted that the above examples are only for understanding this application and do not constitute a limitation on the control signal transmission method of this application. Any simple modifications based on this technical concept are within the protection scope of this application.

[0054] In this embodiment, please refer to Figure 3 and Figure 4In the control signal transmission device, when an external control signal is input, the signal recognition and processing module 10 captures the signal and temporarily stores it in the internal buffer area. Then, the format recognition algorithm is called to analyze the signal in the buffer. The algorithm determines the format type of the signal by detecting specific characteristics of the signal (such as pulse width, voltage amplitude, encoding rules, etc.). After recognition, the signal format information is stored in the device memory for subsequent processing. According to the recognized signal format, the corresponding conversion algorithm is retrieved from the preset conversion rule library. The conversion rule library contains conversion methods between various common signal formats, such as from PWM signal to differential signal, from serial communication signal to DALI protocol signal, etc. After selecting the conversion algorithm, the first signal data in the buffer is read and converted according to the steps specified by the algorithm. During the conversion process, parameters such as the signal timing, amplitude, and encoding method are adjusted to generate a second signal that meets the requirements of the second format. After the conversion is completed, the generated second signal is transmitted to the control signal transmission module 20. The control signal transmission module 20 includes an integrated wire harness that integrates multiple functions such as signal transmission and power supply. Before sending the signal, the control signal transmission module 20 can perform necessary preprocessing on the second signal, such as amplifying the signal amplitude and adjusting the signal frequency, to ensure that the signal can be transmitted stably and reliably in the wire harness. After the preprocessing is completed, the control signal transmission module 20 injects the second signal into the integrated wire harness, and the signal is transmitted along the wire harness to the target load.

After restoration, the first signal is transmitted to the load. The load controls the switching, brightness, color and other parameters of the lighting load according to the instructions of the first signal, so as to achieve precise control of the lighting system.
