Description

Technical Field

[0001] The utility model relates to a control device, in particular to a control device compatible with 0-10V and PUSH dimming. Background Technique

[0002] With the continuous development of lighting technology, dimming control devices have been widely used in various application scenarios. Especially in the fields of commercial lighting, home lighting, and stage lighting, the demand for dimming technology is becoming more diverse and complex. Currently, the common dimming technologies on the market mainly include two methods: 0-10V dimming and PUSH dimming.

[0003] As a relatively mature dimming method, the 0-10V dimming system mainly controls the brightness of the light source by adjusting the change of the input voltage. However, most of the existing 0-10V dimming control devices adopt a pure hardware design. And due to the problem of sink current in the 0-10V receiver, the number of receivers that each 0-10V transmitter can control is limited. This is particularly insufficient in large-scale lighting systems, especially in scenarios where multiple receivers need to work synchronously. In addition, traditional 0-10V dimming devices usually do not have the function of a synchronous interface, resulting in complex wiring and poor scalability, which are difficult to meet the requirements of modern intelligent lighting systems.

[0004] As an emerging dimming method, PUSH dimming directly controls the brightness change of the light source by pressing a button, which has the characteristic of simple operation. However, due to the lack of a standardized interface design, its application in system integration is restricted to a certain extent. Summary of the Invention

[0005] In order to solve the above problems, the utility model provides a control device compatible with 0-10V and PUSH dimming. On the basis of the existing 0-10V receiver, an RJ45 synchronous interface is added, which can be not affected by the 0-10V sink current. Theoretically, an infinite number of 0-10V receivers can be expanded. At the same time, a DIP switch is added, which can set different PWM frequencies and is more suitable for different application environments.

[0006] The utility model is realized through the following technical solutions: A control device compatible with 0-10V and PUSH dimming, comprising:

[0012] The drive output part, connected to the main control part, uses the processed signals to control the load output,

[0014] As a preferred technical solution, the DIP switch setting part is provided with multiple gears of PWM frequency adjustment switches, including at least 2KHz and 16KHz frequencies, for optimizing the load output effect and reducing the power supply whistle in different application environments.

[0015] As a preferred technical solution, the linear power supply part converts the input voltage into a stable 5V voltage for use by each module of the control device.

[0016] As a preferred technical solution, the drive output part is connected with one or more load devices for controlling the working state of the load according to the signals processed by the main control part.

[0017] As a preferred technical solution, the RJ45 synchronous reception part includes two RJ45 interfaces, enabling the control device to communicate synchronously with multiple receivers simultaneously, thus enhancing the scalability and stability of the system.

[0018] As a preferred technical solution, the control device further includes a PUSH dimming interface, which is connected to the main control part, enabling users to achieve dimming control of the lights through button operations.

[0019] The beneficial effects of the present utility model are: by adding an RJ45 synchronous interface, this control device can be not affected by the 0-10V sink current and can theoretically expand an infinite number of 0-10V receivers, greatly enhancing the scalability and applicability of the system, and is especially suitable for applications in large-scale projects;

[0020] This control device is equipped with a DIP switch setting part, which can adjust the PWM frequency of the output end according to actual needs. Especially when the frequencies are 2KHz and 16KHz, they are respectively applicable to application scenarios of enhancing the load output power and reducing the power supply whistle, thus improving the adaptability and flexibility of the device.

[0021] By adding a PUSH dimming interface, users can achieve dimming control of the lights through simple button operations, providing a more convenient and diverse control method, which is suitable for the usage needs of different users.

[0022] The device realizes synchronous communication with multiple receivers through two RJ45 interfaces, further improving the stability of the system and ensuring that there will be no signal delay or loss during multi-device synchronous operations. Brief Description of the Drawings

That is, unless specifically stated, each feature is only an example of a series of equivalent or similar features.

[0029] As Figures 1 - 3 shown, a control device of the present invention that is compatible with 0-10V and PUSH dimming includes a linear power supply part for converting the input voltage into the voltage required for the internal circuit of the control device;

[0030] a 0-10V receiving part for receiving 0-10V dimming signals;

[0031] an RJ45 synchronous receiving part for receiving and transmitting synchronous signals through the RJ45 interface;

[0032] a main control part connected to the 0-10V receiving part and the RJ45 synchronous receiving part for processing the received signals;

[0033] The DIP switch setting part is set on the main control part and is used to set the PWM frequency of the output terminal;

[0034] The drive output part is connected to the main control part and uses the processed signal to control the load output.

[0035] The RJ45 synchronous receiving part is connected in series with multiple 0-10V receivers through the RJ45 interface, so that the control device is not affected by the 0-10V sink current and can expand multiple 0-10V receivers for compatible control of large-scale projects.

[0036] Among them, the DIP switch setting part is provided with multiple gears of PWM frequency adjustment switches, including at least 2KHz and 16KHz frequencies, which are used to optimize the load output effect and reduce the power supply whistle in different application environments.

[0037] The linear power supply part converts the input voltage into a stable 5V voltage for each module of the control device to use.

[0038] In this embodiment, the drive output part is connected to one or more load devices and is used to control the working state of the load according to the signal processed by the main control part.

[0039] Among them, the RJ45 synchronous receiving part includes two RJ45 interfaces, so that the control device can communicate with multiple receivers synchronously at the same time, thereby improving the system scalability and stability.

[0040] Among them, the control device further includes a PUSH dimming interface, which is connected to the main control part, enabling the user to achieve dimming control of the light through key operations.

[0041] During use, the linear power supply part is responsible for converting the externally input voltage (ranging from 12V to 48V) into a stable 5V DC voltage to supply power to each circuit module inside the device. By adopting the LDO (Low Dropout Linear Regulator) technology, the stability of the power supply output voltage is ensured, avoiding the adverse impact of voltage fluctuations on the operation of the entire device;

[0042] The 0-10V receiving part is used to receive the dimming signal from the 0-10V transmitter. The dimming signal is input in the form of an analog voltage and is converted into a digital signal through an A / D (Analog-to-Digital Converter) and transmitted to the main control part for processing. The 0-10V receiving part can accurately respond to the change of the dimming signal and achieve precise control of the light source brightness.

[0043] The RJ45 synchronous receiving part is connected in series with multiple 0-10V receivers through a standard RJ45 interface to achieve synchronous reception and transmission of signals. This part can not only receive external synchronous signals, but also transmit the dimming signal to the main control part in real time, so that multiple receivers can respond to the same dimming instruction simultaneously, ensuring the synchronous operation of the entire system. Through the extended design of the RJ45 interface, this device can theoretically expand an infinite number of 0-10V receivers without being affected by the 0-10V sink current, greatly improving the expansion ability of the system.

[0044] The main control part consists of an MCU (Micro Control Unit), which is the core control unit of the entire device. It receives and processes signals from the 0-10V receiving part and the RJ45 synchronous receiving part, and calculates the required PWM (Pulse Width Modulation) output signal according to the set algorithm. By analyzing the dimming signal in real time, the MCU can quickly respond and transmit the result to the drive output part to achieve precise control of the load. In addition, the main control part is also connected to the DIP switch setting part, which is used to adjust the PWM frequency to meet different application requirements.

[0045] The DIP switch setting part consists of a group of DIP switches. Users can set different PWM frequencies by toggling the switches. The device presets multiple PWM frequency options, such as 2KHz and 16KHz, etc. Among them, when the frequency is set to 2KHz, the load output power can be enhanced, which is suitable for scenarios with large power requirements; while when the frequency is set to 16KHz, the power supply whistling sound that can be heard by the human ear can be effectively eliminated, improving the user experience. The set frequency information will be transmitted to the main control part in real time, affecting the output of the PWM signal.

[0046] The drive output part connects the main control part and the external load, and is used to convert the PWM signal processed by the main control part into the actual output voltage or current to directly control the working state of the load. According to the instruction of the main control part, the drive output part can accurately adjust the brightness of the light source to achieve stable and reliable dimming operation.

[0047] The above is only the specific implementation manner of the present utility model, but the protection scope of the present utility model is not limited thereto. Any change or replacement that can be thought of without creative work should be covered by the protection scope of the present utility model. Therefore, the protection scope of the present utility model should be subject to the protection scope defined by the claims.
