DETAILED DESCRIPTION

[0023] In order to make the purpose, technical solution and advantages of the utility model clearer, the technical solution of the utility model will be described clearly and completely in conjunction with the drawings in the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments.

[0025] Figure 1 This is one of the principle block diagrams of the USB wireless transceiver controller provided by the embodiment of the utility model. Figure 2 This is the second principle block diagram of the USB wireless transceiver controller provided by the embodiment of the utility model, such as Figure 1 and Figure 2As shown, the utility model provides a USB wireless transceiver controller, including a USB plug 100, a radio frequency chip 200, a plurality of indicator lights 300, a button 400 and a radio frequency antenna unit 500. The USB plug 100 is electrically connected to the radio frequency chip 200, and the radio frequency chip 200 is electrically connected to the indicator lights 300, the button 400 and the radio frequency antenna unit 500 respectively. The USB plug 100 can be plugged into the USB interface of a lamp or the USB interface of a lamp control device (such as a computer). The utility model can be used to realize DMX signal transmission between a lamp control device and a lamp or DMX signal transmission between lamps. The radio frequency chip 200 and the radio frequency antenna unit 500 are used to realize the transmission and / or reception of DMX signals. The button 400 is used to turn on or off the USB wireless transceiver controller, and the indicator light 300 is used to indicate various states of the USB wireless transceiver controller.

[0026] Figure 3 This is a circuit diagram of the USB wireless transceiver controller provided by the utility model, such as Figure 3 As shown, the first pin of the USB plug 100 is connected to a 5V DC power supply VCC, which is filtered by a capacitor C1 to power the RS485 chip U2, and filtered by capacitors C3-C5 to power the voltage regulator chip U1. The voltage regulator chip U1 converts VCC into a 3.3V voltage, which is filtered by capacitors C2 and C6-C7 to power the RF chip 200. The fourth pin of the USB plug 100 is grounded; the second pin and the third pin of the USB plug 100 are respectively connected to the seventh pin and the sixth pin of the RS485 chip U2 for bidirectional transmission of DMX differential signals; the fifth pin to the ninth pin of the USB plug 100 are respectively connected to the RF chip 200 via resistors for transmitting SPI protocol signals and clock signals.

[0027] Furthermore, the USB plug 100 is a male plug of a type A interface supporting the USB 3.0 standard, with a maximum transmission speed of 500MB per second. Specifically, the second pin of the USB plug 100 is externally connected to a pull-down resistor R1, and the third pin is externally connected to a pull-up resistor R2. The data is converted into DATA data by the RS485 chip U2 and communicates with the RF chip 200. The 1st pin of the RS485 chip U2 is a receiving pin, and a standard 3.3V digital signal is obtained through a voltage divider network formed by resistors R3 and R4, and transmitted to the DMX-RDX pin of the RF chip 200. The 2nd pin of the RS485 chip U2 is connected to the 485-RE pin of the RF chip 200, and the RF chip 200 controls the reception or closing of the DATA data of the RS485 chip U2. The 3rd pin of the RS485 chip U2 is connected to the 485-DE pin of the RF chip 200, and the RF chip 200 controls the sending or closing of the DATA data of the RS485 chip U2. The RS485 chip U24 pin is connected to the 485-TXD pin of the RF chip 200, and the RF chip 200 sends DATA data. The fifth pin of the USB plug 100 is connected to the IRQ pin of the RF chip 200 through a resistor R13, and the RF chip 200 uses the IRQ function of the SPI protocol to send the current working status. The sixth pin of the USB plug 100 is connected to the CS pin of the RF chip 200 through a resistor R14, and the RF chip 200 uses the CS chip select function of the SPI protocol to receive the working mode command. The seventh pin of the USB plug 100 is connected to the SCK pin of the RF chip 200 through a resistor R15 to receive the SCK clock command. The eighth pin of the USB plug 100 is connected to the MOSI pin of the RF chip 200 through a resistor R16 to receive the digital signal of the SPI protocol. The ninth pin of the USB plug 100 is connected to the MISO pin of the RF chip 200 through a resistor R17 to send the digital signal of the SPI protocol.

[0028] Furthermore, the indicator light 300 includes a first indicator light 310 for indicating the strength of the received signal, a second indicator light 320 for indicating the signal status, and a third indicator light 330 for indicating the link status. Optionally, the first indicator light 310 includes multiple LED lights of different colors. Specifically, if the received signal strength is lower than 10%, a red LED light 313 can be used for indication; if the received signal strength is higher than 20% and lower than 60%, an orange LED light 312 can be used for indication; if the received signal strength is higher than 60%, a green LED light 311 can be used for indication. When the received signal strength is higher than 60%, the transistor Q1 is turned on and the orange LED light 312 is turned off.

[0029] The second indicator light 320 is a STATUS-LED light, which is green in color. If the USB wireless transceiver controller is working in the receiving state, no transmitter is connected when it is turned off (0V); if it flashes for 100ms when turned off (0V) / 100ms when turned on (3.3V), it means that it is connected to the transmitter, but there is no valid RF link. If it flashes for 900ms when turned off (0V) / 100ms when turned on (3.3V), it means that there is a valid RF link and the DMX signal does not exist. If it is always on, it means that there is a valid RF link and the DMX signal exists. If the USB wireless transceiver controller is working in the transmitting state, if it is always on, it means that there is a valid RF link and the DMX signal exists. If it flashes for 100ms when turned off (0V) / 100ms when turned on (3.3V), it means that the receiver is being connected. If it flashes for 200ms when turned off (0V) / 100ms when turned on (3.3V), it means that the connection with the receiver is being cancelled. If it flashes according to the principle of 900ms when off (0V) / 100ms when on (3.3V), it indicates a valid RF link and the DMX signal does not exist.

[0030] The third indicator light 330 is a LINK-LED light, which is blue in color. A high level (3.3V) indicates a connected state; a low level (0V) indicates an unconnected state. Receiving state: A high level (3.3V) on the RF link LED output (RF-LED) indicates that the receiver is within the range of the connected transmitter and there is a valid RF link from the transmitter. Transmitting state: A high level (VDD) on the RF link LED output (RF-LED) indicates that there is a valid RF link.

[0031] Furthermore, the button 400 is a transient (monostable) touch button S1, and the external pull-up resistor R5 pulls the voltage up to 3.3V to ensure normal operation. Pull the signal low (press the button 400) for 0.1-1 second to connect the transmitter. Keep the signal low (press the button 400) for more than 3 seconds to cancel the connection (cancelling the connection can be the current connection or the remembered connection, that is, resetting to a blank state). By short-pressing the link switch 3 times, and then pressing and holding the button for at least 3 seconds, you can enter the receive and transmit mode selection.

Specifically, a spiral antenna connection seat 510J1 and an IPEX gold-plated patch radio frequency connection line 530 seat J2 are provided on the circuit board.

[0033] Furthermore, the RF chip 200 is a multiplexed RF chip WIR1, which is a RF multiplexing chip module with cognitive functions.
