Description

Technical Field

[0001] This invention relates to the field of stage lighting technology, and more particularly to a photoelectric conversion device and its control system for stage equipment. Background Technology

[0002] Currently, data transmission and signal control communication for stage lights typically rely on electrical signal transmission via data cables, or wireless signal transmission via Bluetooth or WiFi modules. The drawback of data cable transmission is that longer cables increase resistance, and excessively long transmission distances limit communication. For example, electrical signals suffer from signal attenuation, distortion, slow transmission rates, and data integrity issues, limiting transmission distances to 5-10 meters. Wireless signal transmission, besides being limited by distance, is also susceptible to signal attenuation, distortion, and delays due to environmental obstacles or weather changes. Bluetooth wireless signals typically have a transmission distance of 2-3 meters, while WiFi signals typically have a transmission distance of 200-300 meters. These transmission distances are far from sufficient for communication between the control console and stage lights. Therefore, achieving long-distance communication with high transmission rates and undistorted signals has become a pressing technical challenge. Summary of the Invention

[0026] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0027] As attached Figure 1 As shown, a photoelectric conversion device 3 for stage equipment is disclosed. The stage equipment includes a control console 1 and a stage light 2. Both the control console 1 and the stage light 2 are equipped with photoelectric conversion devices 3. The photoelectric conversion device 3 includes an electrical signal connection port 4 (model RJ45), a network isolation transformer 5 (model GST_5009), a processor 6 (model RTL8211FS-CG or RTL8111H-CG), a capacitive coupling module 7, a photoelectric module 8, and a power supply module 9. The power supply module 9 mainly supplies power to the processor 6 and the photoelectric module 8. The electrical signal connection port 4 is used as an electrical signal input or output terminal. The electrical signal connection port 4 is electrically connected to the processor 6 through the network isolation transformer 5.

[0028] When the electrical signal connection port 4 serves as the electrical signal output terminal of the control console 1, the electrical signal connection port 4 sends the electrical signal to the processor 6 through the network isolation transformer 5. The processor 6 then sends the processed electrical signal to the photoelectric module 8 through the capacitive coupling module 7. The photoelectric module 8 converts the electrical signal into an optical signal and sends it to the stage lamp 2. At this time, the photoelectric module 8 of the photoelectric conversion device 3 of the stage lamp 2 converts the received optical signal into an electrical signal. The photoelectric module 8 sends the converted electrical signal to the processor 6 through the capacitive coupling module 7. The processor 6 processes the electrical signal and sends it to the electrical signal connection port 4 through the network isolation transformer 5. At this time, the electrical signal connection port 4 serves as the electrical signal input terminal, and the stage lamp 2 executes corresponding command actions based on this electrical signal. Similarly, the feedback electrical signal conversion process of the stage lamp is also electrical signal-optical signal-electric signal. Finally, the control console 1 makes corresponding feedback actions based on the feedback electrical signal. It can be understood that the stage equipment can achieve bidirectional communication through the photoelectric conversion device 3.

[0029] As attached Figure 8 As shown, the optical signal transmission between the photoelectric conversion device 3 of the control console 1 and the photoelectric conversion device 3 of the stage light 2 is through an optical signal transmission medium, specifically optical fiber. Optical fiber has the characteristics of wide bandwidth, low loss, light weight, strong anti-interference ability, high fidelity, and reliable working performance. Through optical fiber, the communication distance between the control console 1 and the stage light 2 can reach several kilometers or even tens of kilometers, thereby ensuring that the signal transmission is not distorted and ensuring the integrity and timeliness of data transmission.

[0030] As attached Figure 1 As shown, the optoelectronic module 8 includes an optical module 81 for connection with an optical fiber and a connector 82 for electrical connection after the optical module 81 is inserted.

The VDD33 terminal of the power module 9 is electrically connected to the first filter module 91, and the first filter module 91 provides a 3.3V operating voltage to the processor 6 through the AVDD33 terminal. The first filter module 91 mainly includes capacitors C1, C2, C3, and C4 to form a capacitor filter circuit, thereby reducing voltage fluctuations and making the output voltage more stable. The power module 9 and the first filter module 91 are electrically connected through a ferrite bead RF1, which further improves the stability and reliability of the power circuit.

[0032] As attached Figure 6 and attached Figure 7 As shown, the power module 9 is electrically connected to the connector 82 through the second filter module 92. The second filter module 92 mainly consists of capacitors C35, C36, C37, C38, C39, and C22, as well as inductors L2 and L3. Specifically, the second filter module 92 is electrically connected to pins 15 and 16 of the connector 82 through the VCCR and VCCT terminals, respectively. Pins 2, 4, 5, 6, and 8 of the connector 82 are respectively connected to the VDD33 terminal of the power module 9 through resistors R56, R55, R54, R53, and R52, thereby providing a stable 3.3V operating voltage to the connector 82 and ensuring the stability and reliability of the circuit during operation.

[0033] As attached Figure 4 As shown, the capacitor coupling module 7 includes capacitors C27, C28, C29 and C30; the processor 6 is electrically connected to the connector 82 through these capacitors. The capacitor coupling module 7 transmits the AC signal from the front-end circuit to the back-end circuit while preventing electromagnetic interference.

[0034] Further details are attached. Figure 5 As shown, the VDD33 terminal of the power module 9 is also electrically connected to the DVDDRG terminal through the RF2 ferrite bead. The DVDDRG terminal is also connected to capacitors C5 and C6 for filtering. The DVDDRG terminal serves as a reference voltage terminal, providing a stable reference point to ensure that the entire circuit operates in a stable state.

[0035] As attached Figure 1 As shown, the processor 6 is connected to a 25MHz crystal oscillator module, a reset module, a Link indicator module, and a mode selection configuration module. The 25MHz crystal oscillator module mainly provides the clock signal to the processor 6, which can oscillate up to 25,000,000 times per second. The reset module provides a stable reset signal to the processor 6 to ensure that the processor 6 can reliably reset and resume normal operation under power fluctuations, system failures, or other abnormal conditions. The mode selection configuration module can automatically select 10Mbps mode, 100Mbps mode, and 1000Mbps mode according to the transmission rate, while the Link indicator module can light up the corresponding indicator light according to the corresponding configuration mode.

[0036] As attached Figure 8 As shown, the present invention also provides a control system for stage equipment, including a control console 1, at least one stage light 2, and the photoelectric conversion device 3, wherein the optical signal transmission between the photoelectric conversion device 3 of the control console 1 and the photoelectric conversion device 3 of the stage light 2 is through an optical signal transmission medium.
