This allows the terminal device to configure and manage the communication device. When the console management interface between the communication device and the terminal device malfunctions, such as due to line or equipment failure, the user cannot quickly locate the fault. Summary of the Invention

[0003] The purpose of this application is to provide a fault monitoring device for the console management interface of a communication device, which can solve the technical problem in the prior art that the fault point cannot be quickly located when the console management interface between the communication device and the terminal device fails.

[0020] If the indicator light on the receiving side remains off when the terminal device sends command information to the communication device, it is determined that the console cable is faulty.

[0021] If the indicator light on the receiving side is flashing and the indicator light on the sending side is off when the terminal device sends instruction information to the communication device, it is determined that the console management interface of the communication device has failed.

[0022] If the indicator light on the transmitting side is flashing and no information is displayed on the console management interface of the terminal device, it is determined that the serial port configuration managed by the console has failed.

[0054] The present application will be described in detail below with reference to the specific embodiments shown in the accompanying drawings. However, these embodiments do not limit the present application. Any structural, methodological, or functional modifications made by those skilled in the art based on these embodiments are included within the protection scope of the present application.

[0055] Please refer to Figure 1 This application provides a fault monitoring device for the console management interface of a communication device 100. The device includes an RJ45 interface module 11, a main controller 12, and an indicator light control module 13.

[0056] RJ45 interface module 11 includes indicator lights (not shown in the figure). RJ45 interface module 11 is configured to connect to the console management interface of terminal device 200 via a console cable. Exemplarily, one end of the console cable connects to RJ45 interface module 11 of communication device 100, and the other end connects to RJ45 interface module / DB9 interface / USB interface of terminal device 200. It should be noted that RJ45 interface module 11 uses an RJ45 connector. The appearance of the RJ45 connector is similar to that of an RJ45 network port, but the signal definition of the RJ45 connector is different. This RJ45 connector carries RS-232 signals and follows the RS-232 serial port protocol.

[0057] The main controller 12 includes a console management interface (not shown in the figure), which includes a UART module 121. For example, the main controller 12 uses an MCU chip, which implements data communication with the console management interface through a UART (Asynchronous Receiver / Transmitter) interface. The UART module 121 is connected to the RJ45 interface module 11. The UART module 121 transmits / receives UART signals to achieve console management between the communication device 100 and the terminal device 200. Console management enables configuration management of the communication device 100, such as device IP address management, user and password management, etc.

[0058] The indicator light control module 13 is connected to the UART module 121 and the RJ45 interface module 11 respectively. The indicator light control module 13 is configured to receive UART signals and drive the display status of the indicator lights of the RJ45 interface module 11 according to the UART signals. Based on the display status of the indicator lights, it determines whether the console management interface of the communication device 100 / the console management interface of the terminal device 200 has failed.

[0059] In the prior art, the RJ45 interface module of the console management interface of the communication device 100 typically uses an RJ45 connector with or without indicator lights. RJ45 connectors with indicator lights are usually not used because they are different from Ethernet RJ45 connectors. The indicator lights of Ethernet RJ45 connectors can be directly driven by Ethernet link signals to turn on and off. However, the RJ45 interface module of the console management interface uses RS-232 signals, and the indicator lights of the RJ45 interface module cannot be directly turned on and off by driving RS-232 signals. Therefore, the indicator lights of the RJ45 interface module of the console management interface of the communication device 100 are usually not used in the prior art.

[0060] Therefore, in this embodiment, the indicator light control module 13 drives the received UART signal to turn the indicator light of the RJ45 interface module 11 on and off. The UART signal is the communication signal of the console management interface of the main controller 12. Therefore, the user can directly observe the display status of the indicator light of the RJ45 interface module 11 to determine whether the console management interface of the communication device 100 / terminal device 200 has failed. This method can quickly locate the faulty node in the console management link, enabling the user to more directly and intuitively locate and maintain the communication device, bringing convenience to the user in maintenance and management.

[0061] One embodiment of this application, such as Figure 2 As shown, the UART module 121 includes a first UART transmitter 1211 and a first UART receiver 1212. The device also includes an RS-232 interface module 14, which includes a second UART transmitter 141, a second UART receiver 142, a first UART transmitter 143, and a first UART receiver 144. The RS-232 interface 11 includes a second UART transmitter 111 and a second UART receiver 112. The first UART transmitter 1211 is electrically connected to the second UART receiver 142, the first UART receiver 1212 is electrically connected to the second UART transmitter 141, the first UART transmitter 143 is electrically connected to the second UART receiver 112, and the first UART receiver 144 is electrically connected to the second UART transmitter 111. The first UART transmitter 1211 outputs a UART transmission signal to the second UART receiver 142. The RS-232 interface module 14 converts the received UART transmit signal into an RS-232 transmit signal and transmits it to the second RS-232 receiver 112 via the first RS-232 transmitter 143. The RJ45 interface module 11 outputs the RS-232 transmit signal to the console management interface of the terminal device 200 via a console cable, so that the console management interface of the terminal device 200 can process the received RS-232 transmit signal. The RJ45 interface module 11 receives the RS-232 receive signal from the console management interface of the terminal device 200 via a console cable and transmits it to the first RS-232 receiver 144 via the second RS-232 transmitter 111. The first RS-232 receiver 144 converts the RS-232 received signal into a UART received signal and sends the UART received signal to the first UART receiver 1212 through the second UART transmitter 141, so that the master controller 12 can process the UART received signal, thereby realizing data communication between the console management interface of the communication device 100 and the console management interface of the terminal device 200, and thus realizing the console management and configuration of the device.

[0062] One specific embodiment of this application, such as Figure 3As shown, UART module 121 includes CPU chip U2A, RS-232 interface module 14 includes RS-232 chip U1, U1's chip model is SP3232EU, and RJ45 interface module 11 includes RJ45 connector J1. The first UART transmitter 1211 (pin A1) of CPU chip U2A outputs a UART transmit signal (UART-TX) to the second UART receiver 142 (pin 11) of RS-232 chip U1. RS-232 chip U1 converts the received UART transmit signal into an RS-232 transmit signal (CONSOLE_TX) and transmits it through the first RS-232 transmit terminal 143 (pin 14) to the second RS-232 receive terminal 112 (pin A3) of RJ45 connector J1. RJ45 connector J1 outputs the RS-232 transmit signal (CONSOLE_TX) to the console management interface of terminal device 200 via a console cable, so that the console management interface of terminal device 200 can process the received RS-232 transmit signal. RJ45 connector J1 receives the RS-232 receive signal (CONSOLE_RX) sent from the console management interface of terminal device 200 via a console cable and transmits the RS-232 receive signal (UART-TX) through the second RS-232 transmit terminal 111 (pin A6) to the first RS-232 receive terminal 144 (pin 13) of RS-232 chip U1. The first RS-232 receiver 144 converts the RS-232 received signal (CONSOLE_RX) into a UART received signal (UART-RX), and sends the UART received signal (UART-RX) to the first UART receiver 1212 (pin A3) of the CPU chip U2A through the second UART transmitter 141 (pin 12), so that the main controller 12 processes the UART received signal (UART-RX), thereby realizing data communication between the console management interface of the communication device 100 and the console management interface of the terminal device 200, and thus realizing the console management and configuration of the device.

[0063] One embodiment of this application, such as Figure 4As shown, the indicator light control module 13 includes a transmitting indicator light control unit 131 and a receiving indicator light control unit 132. The indicator lights of the RJ45 interface module 11 include a transmitting side indicator light 113 and a receiving side indicator light 114. The first UART transmitting end 1211 is electrically connected to the transmitting indicator light control unit 131, the first UART receiving end 1212 is electrically connected to the receiving indicator light control unit 132, the transmitting indicator light control unit 131 is electrically connected to the receiving side indicator light 114, and the receiving indicator light control unit 132 is electrically connected to the transmitting side indicator light 113. The first UART transmitting end 1211 outputs a UART transmitting signal to the transmitting indicator light control unit 131, and the transmitting indicator light control unit 131 controls the display state of the receiving side indicator light 114 according to the level state of the UART transmitting signal. The first UART receiving end 1212 receives the UART receiving signal output from the RS-232 interface module 14, and the receiving indicator light control unit 132 controls the display state of the transmitting side indicator light 113 according to the level state of the UART receiving signal.

[0064] Specifically, when the UART transmit signal is high, the transmit indicator control unit 131 drives the receive-side indicator 114 to be off; when the UART transmit signal is normally low, the transmit indicator control unit 131 drives the receive-side indicator 114 to be on; when the UART transmit signal undergoes a level transition, the transmit indicator control unit 131 drives the receive-side indicator 114 to flash. When the UART receive signal is normally high, the receive indicator control unit 132 drives the transmit-side indicator 113 to be off; when the UART receive signal is normally low, the receive indicator control unit 132 drives the transmit-side indicator 113 to be on; when the UART receive signal undergoes a level transition, the receive indicator control unit 132 drives the transmit-side indicator 113 to flash.

[0065] In this embodiment, the transmit indicator control unit 131 drives the display state of the receive-side indicator 114 of the RJ45 interface module 11 according to the level state of the received UART transmit signal, i.e., on, off, or flashing. The receive indicator control unit 132 drives the display state of the transmit-side indicator 113 of the RJ45 interface module 11 according to the level state of the received UART receive signal, i.e., on, off, or flashing. The user can determine whether the line between the console management interface of the communication device 100 and the console management interface of the terminal device 200 is normal or faulty based on the display states of the receive-side indicator 114 and the transmit-side indicator 113. This method is simple and can quickly locate whether the line is normal.

[0066] In one embodiment of this application, the transmit indicator control unit 131 includes a first MOSFET, a first resistor, and a first capacitor. The first resistor and the first capacitor form a first charging delay circuit. The receive-side indicator 114 includes pins LED2+ and LED2-. The UART transmit signal is electrically connected to the gate of the first MOSFET. One end of the first resistor is electrically connected to the drain of the first MOSFET, and the other end is electrically connected to pin LED2+. One end of the first capacitor is electrically connected to the drain of the first MOSFET, and the other end is electrically connected to pin LED2-. When the UART transmit signal is high, the first MOSFET is off, keeping the receiver-side indicator light 114 off. When the UART transmit signal is low, the first MOSFET is on, and when the voltage across the receiver-side indicator light 114 is greater than or equal to the lighting voltage threshold, the indicator light 114 is turned on, and the first charging delay circuit performs charging. When the UART transmit signal flips from low to high, the first MOSFET is off, and the first charging delay circuit performs discharging, keeping the receiver-side indicator light 114 on until the voltage across it is less than the lighting voltage threshold, at which point the indicator light 114 turns off, thus extending the lighting time of the receiver-side indicator light 114. The setting of the lighting voltage threshold is related to the chip design of the RJ45 interface module 11.

[0067] In one embodiment of this application, the receive indicator control unit 132 includes a second MOSFET, a second resistor, and a second capacitor. The second resistor and the second capacitor form a second charging delay circuit. The transmit side indicator 113 includes pins LED1+ and LED1-. The UART receive signal is electrically connected to the gate of the second MOSFET. One end of the second resistor is electrically connected to the drain of the second MOSFET, and the other end is electrically connected to pin LED1+. One end of the second capacitor is electrically connected to the drain of the second MOSFET, and the other end is electrically connected to pin LED1-. When the UART receive signal is high, the second MOSFET is off, keeping the transmitting side indicator light 113 off. When the UART receive signal is low, the second MOSFET is on. When the voltage across the transmitting side indicator light 113 is greater than or equal to the brightness voltage threshold, the transmitting side indicator light 113 is turned on, and the second charging delay circuit performs charging. When the UART receive signal flips from low to high, the second MOSFET is off, and the second charging delay circuit performs discharging, keeping the transmitting side indicator light 113 on until the voltage across the transmitting side indicator light 113 is less than the lighting voltage threshold, at which point the transmitting side indicator light 113 turns off, thus extending the lighting time of the transmitting side indicator light 113. The setting of the lighting voltage threshold is related to the chip design of the RJ45 interface module 11.

[0068] In this embodiment, the UART transmit signal and UART receive signal transition rapidly during level changes. If the signal is used to directly drive the indicator light, the indicator light will be weak, making it difficult for the user to observe the changes in the indicator light status with the naked eye. Therefore, the charging and discharging functions of the first and second charging delay circuits can extend the indicator light's illumination time, allowing the user to directly observe the changes in the indicator light status with the naked eye. This enables the correct positioning of the line status between the console management interface of the communication device 100 and the console management interface of the terminal device 200.

[0069] One specific embodiment of this application, such as Figure 3 As shown, the transmit indicator control unit 131 includes a first MOSFET Q2, a first resistor R6, and a first capacitor C2. The first resistor R6 and the first capacitor C2 form a first charging delay circuit. The receive-side indicator 114 of the RJ45 connector J1 includes pins LED2+ and LED2-. The UART transmit signal (UART-TX) is electrically connected to the gate of the first MOSFET Q2. One end of the first resistor R6 is electrically connected to the drain of the first MOSFET Q2, and the other end is electrically connected to pin LED2+. One end of the first capacitor C2 is electrically connected to the drain of the first MOSFET Q2, and the other end is electrically connected to pin LED2-. The receive indicator control unit 132 includes a second MOSFET Q1, a second resistor R3, and a second capacitor C1. The second resistor R3 and the second capacitor C1 form a second charging delay circuit. The transmit-side indicator 113 includes pins LED1+ and LED1-. The UART receive signal (UART-RX) is electrically connected to the gate of the second MOSFET Q1. One end of the second resistor R3 is electrically connected to the drain of the second MOSFET Q1, and the other end is electrically connected to the LED1+ pin. One end of the second capacitor C1 is electrically connected to the drain of the second MOSFET Q1, and the other end is electrically connected to the LED1- pin. For example, the capacitance of the first capacitor C2 and the second capacitor C1 is 1uF, and the resistance of the first resistor R6 and the second resistor R3 is 1KΩ.

[0070] Specifically, when the UART transmit signal (UART-TX) is high, the first MOSFET Q2 is off, and the output RX-LED signal drives the receiving-side indicator light 114 to be off. When the UART transmit signal (UART-TX) is low, the first MOSFET Q2 is on, and R6 and C2 form a first charging delay circuit. This circuit charges during this stage. Because R6 has a smaller resistance and C2 has a larger resistance, the charging time t1 = R6 * C2. When the voltage across the receiving-side indicator light 114 reaches the lighting voltage threshold, the output RX-LED signal drives the receiving-side indicator light 114 to light up, and C2 simultaneously stores energy. When the UART transmit signal (UART-TX) flips from low to high, the first MOSFET Q2 is off, and C2 discharges the energy stored in the previous stage, keeping the receiving-side indicator light 114 on until the voltage across it falls below the lighting voltage threshold, at which point the receiving-side indicator light 114 turns off. Users can adjust the value of C2 according to the actual situation to adjust the lighting extension time of the receiver-side indicator light 114.

[0071] Specifically, when the UART receive signal (UART-RX) is high, the second MOSFET Q1 is off, and the output TX-LED signal drives the transmitting side indicator light 113 to remain off. When the UART receive signal (UART-RX) is low, the second MOSFET Q1 is on, and R3 and C1 form a second charging delay circuit. This circuit charges during this stage. Because R3 has a smaller resistance and C1 has a larger resistance, the charging time t1 = R3 * C1. When the voltage across the transmitting side indicator light 113 reaches the lighting voltage threshold, the output TX-LED signal drives the transmitting side indicator light 113 to light up, and C1 simultaneously stores energy. When the UART receive signal (UART-RX) flips from low to high, the second MOSFET Q1 is off, and C1 discharges the energy stored in the previous stage, keeping the transmitting side indicator light 113 on until the voltage across it falls below the lighting voltage threshold, at which point the transmitting side indicator light 113 turns off. Users can adjust the value of C1 according to the actual situation to adjust the lighting extension time of the transmitting side indicator light 113.

[0072] In one embodiment of this application, when both the receiving-side indicator light 114 and the transmitting-side indicator light 113 are off, it is determined that the console management interface of the communication device 100 and the console management interface of the terminal device 200 are connected but there is no data transmission. The console management interface of the communication device is typically used during device debugging and maintenance, and is generally not used during normal operation. The console management interface does not actively send signals to the terminal device. At this time, the UART transmit signal and UART receive signal are idle and at a high level. Therefore, when both the receiving-side indicator light 114 and the transmitting-side indicator light 113 are off, there is a normal connection between the console management interface of the communication device 100 and the console management interface of the terminal device 200, but no data transmission. When both the receiving-side indicator light 114 and the transmitting-side indicator light 113 are flashing, it indicates that the UART transmitting side of the main controller outputs a data signal, and the UART receiving side receives the data signal. Therefore, it is determined that the data transmission between the console management interface of the communication device and the console management interface of the terminal device is normal.

[0073] In one embodiment of this application, when a user manages the communication device 100 through the console management software of the terminal device 200, if the receiving-side indicator light 114 remains off when the terminal device 200 sends command information to the communication device 100, it indicates that the communication device 100 has not received a signal, and the console cable is determined to be faulty. In another application scenario where the user manages the communication device 100 through the console management software of the terminal device 200, if the transmitting-side indicator light 113 is flashing and the receiving-side indicator light 114 is off when the terminal device 200 sends command information to the communication device 100, the flashing transmitting-side indicator light 113 indicates that the UART receiving side of the communication device 100 has received a data signal, while the off receiving-side indicator light 114 indicates that the UART transmitting side of the communication device 100 has not sent a data signal, thus the console management interface of the communication device 100 is determined to be faulty. In another application scenario where the user manages the communication device 100 through the console management software of the terminal device 200, if the transmitting side indicator light 113 is flashing and no information is displayed on the console management interface of the terminal device, it is determined that the console management serial port configuration has failed, such as a problem with the serial port interface parameter configuration, and the baud rate, port, etc. need to be reconfigured.
