Description

Technical Field

[0002] Optical communication equipment is a communication device that uses light waves to transmit information. Optical communication equipment usually works normally without abnormalities.

[0042] In conjunction with the accompanying drawings, some embodiments of the present application are described in detail below. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0043] In response to the problem that optical communication equipment cannot start normally, the present application provides a method for starting optical communication equipment. When the optical communication equipment starts abnormally, the detection signal of the optical module collected is used to determine whether the detection signal meets the preset voltage requirement, and the abnormal connection between the optical module and the optical fiber is eliminated. The PHY chip is reset multiple times to solve the problem that the optical communication equipment is disturbed by the environment at the moment of power-on, the power supply is unstable, and the PHY chip is abnormal. The present application realizes the troubleshooting of the normal connection between the optical module and the optical fiber, and can restore the PHY chip to normal. After the optical communication equipment is started, the optical fiber interface can establish a normal connection and data can be transmitted normally.

[0044] Before describing the startup method of the optical communication device of the present application, the structure of the optical communication device is first introduced accordingly.

[0045] Figure 1The schematic diagram of the structure of the optical communication device 100 proposed in the embodiment of the present application is shown. The optical communication device 100 includes but is not limited to a non-network-managed industrial optical fiber transceiver, an optical signal converter, a PoE (Power over Ethernet) optical fiber transceiver, etc. Exemplarily, the optical communication device 100 includes: a SOC chip 110 (System on Chip), a plurality of optical modules 120 and a PHY chip 130 (physical, physical layer) equal in number to the optical modules 120, each PHY chip 130 is connected to a corresponding optical module 120, each optical module 120 needs to have an optical fiber inserted, and each PHY chip 130 is connected to the SOC chip 110.

[0046] In the embodiment of the present application, the optical module 120 is used to convert an electrical signal into an optical signal, or convert an optical signal into an electrical signal, so as to realize data transmission. The insertion of the optical fiber can transmit the optical signal generated by the optical module 120 to other devices or networks, and can also receive optical signals from other devices or networks, and convert them into electrical signals for processing by the optical module 120. Each optical module 120 is connected to the PHY chip 130 to realize the physical layer functions of photoelectric conversion and data transmission. Each PHY chip 130 is connected to the SOC chip 110 through the MII interface (Media Independent Interface) and the SMI interface (Serial Management Interface), wherein the PHY chip 130 transmits data with the SOC chip 110 through the MII interface to ensure accurate and efficient data transmission. The PHY chip 130 is connected to the SOC chip 110 through the SMI interface, so that the SOC chip 110 can configure and monitor the status and performance of the PHY chip 130.

[0047] In one embodiment, if Figure 2 As shown, the optical communication device 100 also includes a reset chip 140. The GPIO interface of the SOC chip 110 is connected to the reset chip 140. The reset chip 140 is also connected to each PHY chip 130. The SOC chip 110 is used to send a level signal to the reset chip 140, so that the reset chip 140 sends a reset signal to each PHY chip 130 according to the level state of the level signal to reset each PHY chip 130.

[0048] In another embodiment, the SOC chip 110 integrates basic components such as a CPU (Central Processing Unit), a memory, and a peripheral controller, and also integrates a dedicated processing unit such as an MCU (Microcontroller Unit) or a CPLD (Complex Programmable Logic Device). The SOC chip 110 is provided with a plurality of acquisition ports, each of which is connected to a corresponding optical module 120, and can acquire the detection signal of each optical module 120. The SOC chip 110 is also provided with a serial communication interface to enable the optical communication device 100 to transmit data.

[0049] The method for starting the optical communication device 100 is described below in conjunction with some specific embodiments.

[0050] Figure 3 A flowchart of a startup method of an optical communication device 100 according to an embodiment of the present application is shown. Exemplarily, the startup method of the optical communication device 100 is applied to a SOC chip 110, and specifically includes the following steps:

[0051] S210, when the device is powered on, judging whether each PHY chip 130 is abnormal according to the initial reading result of the detection signal of each optical module 120 by each PHY chip 130, and controlling the abnormally working PHY chip 130 to enter a normal working state;

[0052] Exemplarily, when the optical communication device 100 performs a cold start at a certain moment, the PHY chip 130 is reset for the first time to restore the internal state of the PHY chip 130 to the default value to ensure the normal operation of the optical communication device 100. When the optical communication device 100 is connected to a power source, the SOC chip 110 sends a level signal to the reset chip 140, so that the reset chip 140 sends a reset signal to each PHY chip 130 according to the level signal to reset each PHY chip 130.

[0053] In one embodiment, the PHY chip 130 can directly read the detection signal of the optical module 120. In the optical module 120, the detection signal is a signal used to indicate whether the optical module 120 receives an optical signal, and the state of the detection signal can be displayed by an indicator light on the optical module 120. For example, when the detection signal is at a high level, it indicates that the optical module 120 receives an optical signal, and the corresponding indicator light may light up; and when the detection signal is at a low level, it indicates that the optical module 120 does not receive an optical signal, and the indicator light may turn off.

[0054] In another embodiment, since the optical communication device 100 is disturbed by the environment at the moment of power-on, the power supply is unstable, causing the PHY chip 130 to still be abnormal after the initial reset. The PHY chip 130 that still has an abnormality will make an error in reading the detection signal of the optical module 120, and cannot read the detection signal. If the PHY chip 130 reads the detection signal incorrectly, it is determined that the PHY chip 130 is abnormal, and the optical communication device 100 communicates abnormally. If the PHY chip 130 reads the detection signal, it is considered that the PHY chip 130 can work normally after the initial reset, and then it is detected whether the first voltage of the detection signal is within the preset voltage range, so as to determine whether the optical communication device 100 is working normally according to the detection result. If it is detected that the first voltage is within the preset voltage range, the optical fiber interface has established a normal connection, and the optical signal handshake of the optical communication device 100 is successful; if it is detected that the first voltage is not within the preset voltage range, the optical fiber interface cannot establish a normal connection, and the optical communication device 100 cannot communicate normally.

[0055] In an optional embodiment, the preset voltage range may be [2.2V-5V]. When the voltage of the detection signal of the optical module is within the range of [2.2V-5V], it indicates that the optical fiber interface can establish a normal connection, and when the PHY chip 130 can work normally, the optical signal handshake of the optical communication device 100 is successful.

[0056] In one embodiment, the SOC chip 110 sends a reset signal to the abnormally working PHY chip 130 through the reset chip 140, and resets the abnormally working PHY chip 130 multiple times, so that the PHY chip 130 enters a normal working state. During the process of the SOC chip 110 resetting the PHY chip 130 multiple times, when the SOC chip 110 pulls down the reset pin of the reset chip 140 through the GPIO port, the reset chip 140 receives a level signal and interprets it as a reset command. After receiving the reset command, the reset chip 140 sends a reset signal to each PHY chip 130, so that each PHY chip 130 is reset multiple times, which can restore the reset chip 140 to a normal working state. At this time, the power supply interference during the cold start of the optical communication device 100 has been avoided, and the power supply environment is relatively clean.

[0057] S220 , collecting a detection signal of each optical module 120 , so as to determine the access status between each optical module 120 and the optical fiber according to the detection signal.

[0058] In one embodiment, if Figure 4 As shown, when it is determined that the PHY chip 130 is abnormal, the present application determines the access status of the optical fiber through a fault tolerance mechanism, which specifically includes the following steps:

[0059] S221 , collecting detection signals of each optical module 120 multiple times through a collection port.

[0060] S222, detecting whether the second voltage of the collected detection signal is within a preset voltage range, so as to determine the connection status between each optical module 120 and the optical fiber according to the detection result.

[0061] In an optional embodiment, the acquisition port may be an ADC (Analog-to-Digital Converter) pin, which is used to convert the detection signal into a digital signal, and the SOC chip 110 determines the connection state between the optical module 120 and the optical fiber according to the collected detection signal. For example, if the connection between the optical module 120 and the optical fiber is poor, it may cause voltage fluctuations in the detection signal, and the ADC may convert the detection signal into a digital signal. The SOC chip 110 may determine whether the connection state between the optical module 120 and the optical fiber is normal by analyzing the digital signal.

[0062] In another optional embodiment, the acquisition port can be a GPIO pin, and the GPIO pin can be configured as an analog input mode. The SOC chip 110 can directly read the detection signals of each optical module 120 through the GPIO pin in analog input mode, and convert the detection signals into digital signals for processing, and judge the connection status between the optical module 120 and the optical fiber according to a preset voltage.

[0063] S223: If the second voltage of the detection signal is within the preset voltage range, it is determined that the connection state between the optical module 120 and the optical fiber is normal.

[0064] S224: If the second voltage of the detection signal is not within the preset voltage range, it is determined that the connection state between the optical module 120 and the optical fiber is abnormal.

[0065] It can be understood that when the present application detects that the PHY chip 130 cannot read the detection signal of the optical module 120, the SOC chip 110 can collect the detection signals of each optical module 120 to detect whether the connection status between each optical module 120 and the optical fiber is normal, without looseness or damage, and the optical signal can be effectively transmitted between the optical module 120 and the optical fiber.

[0066] S230, if the connection status between each optical module 120 and the optical fiber is normal, then determine whether the optical communication device 100 is operating normally according to the secondary reading result of the detection signal by the normally operating PHY chip 130, so that the normally operating optical communication device 100 enters a normal communication state.

[0067] In one embodiment, when it is determined that the connection between the optical module 120 and the optical fiber is normal, and the power supply interference during the cold start of the optical communication device 100 has been eliminated, the PHY chip 130 is in a normal working state. This application reads the detection signal of each optical module 120 based on the normally working PHY chip 130, and determines that the optical signal handshake of the optical communication device 100 is successful based on the detection signal of each optical module 120, and data transmission can be performed. Figure 5 As shown, the present application determines the working state of the optical communication device 100 according to the detection signal, including the following steps:

[0068] S231, detecting whether a third voltage of the detection signal read by the PHY chip 130 is within a preset voltage range.

[0069] S232: If the third voltage of the detection signal is within the preset voltage range, it is determined that the optical communication device 100 operates normally.

[0070] S233: If the third voltage of the detection signal is not within the preset voltage range, it is determined that the optical communication device 100 is operating abnormally.

[0071] Exemplarily, during the startup of the optical communication device 100, when the PHY chip 130 without any abnormality can detect the detection signals of each optical module 120, and the third voltage of each detection signal meets the preset voltage requirement, it can be considered that the optical signal transmission of the optical communication device has been established, and reliable data transmission can be carried out between other devices.

[0072] In the embodiment of the present application, after the optical communication device 100 is turned on, if the PHY chip 130 cannot read the detection signal of each optical module 120, it is determined that the PHY chip 130 is interfered with and is working abnormally. The present application collects the detection signal of each optical module 120 multiple times through the SOC chip 110. If the second voltage of the detection signal meets the requirement of the preset voltage, it is confirmed that the SOC chip 110 is connected to the optical fiber normally. The SOC chip 110 also resets the PHY chip 130 multiple times to eliminate the influence of the interference on the PHY chip 130. The PHY chip 130 works normally. At this time, the normally working PHY chip 130 can read the detection signal of the optical module 120, and the third voltage of the detection signal meets the requirement of the preset voltage. The optical communication device 100 enters a normal communication state. The present application realizes that the optical communication device 100 intelligently eliminates the influence of power supply interference when it is turned on, without the need for human intervention, thus saving time.
