The multiplexing channel is used for carrying out bidirectional message transmission, and the fault positioning message received by the previous link equipment of the ring mounting equipment is finally transmitted downwards to the protection device to carry out time delay and send out an alarm signal, so that an alarm message is formed and sent upwards.
Preferably, in step a), the message sent by the sending module and the message received by the receiving module are cyclically stored.
In this embodiment, a device inside the channel or a device outside the channel monitors the sending module and the receiving module of each link device, and cyclically stores the message sent by the sending module and the message received by the receiving module.

And recording and storing the sending module state, the receiving module state, the message sent by the sending module and the message received by the receiving module of each link device 2ms before and after the message exception. So as to trace and trace the source of the fault reason.
Referring to fig. 2, fig. 2 is a block diagram of a system for dividing a multiplexing channel link and a fault location unit. Wherein, 1 to 18 are defined fault location units, namely fault points, link 5 is regarded as the same fault location unit through communication, and the fault differentiation at the two positions needs the support of communication network equipment; as does link 14.
Specifically, in step a), each link device is a device in the pilot protection multiplexing channel based on the optical fiber channel, such as a protection device of a relay protection circuit, an interface device, sDH optical electrical transmission device, and the like. As shown in fig. 2, if the current device is a photoelectric conversion device a, the lower ring device is an SDH photoelectric transmission device a, the upper ring device is a protection device a, if the current device is sDH photoelectric transmission device a, the upper ring device is the photoelectric conversion device a, the lower ring device is an SDH photoelectric transmission device B, and so on. That is, when any link device of the link devices receives or sends an abnormal message, it is defined as the current device, and the device in the previous communication link of the link device is the upper ring device, whereas the device in the next communication link of the link device is the lower ring device.
And monitoring a sending module and a receiving module of each link device in the channel. Specifically, a device inside the channel or a device outside the channel monitors a sending module and a receiving module of each link device, and cyclically stores messages sent by the sending module and messages received by the receiving module. It can be understood that each link device has a sending module and a receiving module for realizing bidirectional transmission. The device is arranged inside and outside the existing multiplex channel, and can realize the function of monitoring the running states of the sending module and the receiving module of each link device, thereby detecting the running states of the sending module and the receiving module of each link device, realizing the function of circularly storing the messages sent by the sending module and the messages received by the receiving module, and extracting the required information from the circularly stored messages as required. For example, in the cyclic storage in this embodiment, 100 messages are fixedly stored in a section of memory, and after the memory is full, a new stored message covers an old message, so that cyclic storage is implemented. The bottom hardware of the receiving module or the sending module can check and judge the format and the check code of the data message, so as to determine whether the message received by the receiving module is abnormal or not and whether the message sent by the sending module is abnormal or not, that is, the receiving module and the sending module of each link device can monitor the message received by the receiving module and the message sent by the sending module. The monitoring of the sending module and the receiving module is the basis for realizing the channel fault positioning method in the embodiment, and the monitoring does not need to add extra equipment, so that the original communication running state and environment are not damaged.
The location of the fault point is determined in step B) by dividing the location of the fault point into two cases. When the receiving module of the current device monitors that the message received by the receiving module is abnormal, the step C1) is executed, the source of the abnormal message is searched to confirm the position of the fault point in the multiplexing channel, and when the sending module of the current device monitors that the message sent by the sending module of the current device is abnormal, the step C2) is executed, the source of the abnormal message is searched to confirm the position of the fault point in the multiplexing channel.
In step C1), the transmission module and the reception module of each link device are monitored by the device inside the channel or the device outside the channel, and the operation state of the reception module of the current device is determined.
In step C11), when it is monitored that the receiving module of the current device is operating abnormally, it is indicated that the receiving module of the current device is a fault point, and the source of the received message abnormality is found, so that the fault location message of the current device receiving abnormality is sent to the upper ring device and the lower ring device to determine that the receiving module of the current device is a fault point, so that the fault location message finally reaches the protection device for alarming and uploading.
In step C12), when it is monitored that the receiving module of the current device operates normally and the message received by the receiving module is abnormal, it indicates that the message is sent by the sending module of the upper ring device and is abnormal only through the intermediate link device, so that it can be determined that the sending module of the upper ring device or the intermediate link device is abnormal. At this time, the upper ring device is required to be inserted into the message which is reversely transmitted to the upper ring device by the current device to send a fault confirmation message, and then the abnormal source of the received message is back-verified through C13).
In step C13), the upper ring device receives the failure confirmation message transmitted reversely by the current device, and needs to perform self-verification first to check whether the states of the sending module of the upper ring device and the sent message are abnormal. The operation state of the sending module of the upper ring device is also monitored in real time, and the message sent by the sending module can be verified by calling the circularly stored message. The check results described above may occur in both cases C131) and C132).
In step C131), when the sending module and the sent message of the upper ring device that are checked are in an abnormal state, it is described that a fault point appears in the sending module of the upper ring device, the source of the abnormal message received by the current device receiving module is found, and then an abnormal fault positioning message needs to be sent to the previous link device of the upper ring device and the current device, so that the fault positioning message finally reaches the protection device for alarming and sending.
In step C132), when the sending module and the sent message of the upper ring device that are checked are in normal states, it indicates that a fault point is present on the intermediate link device between the upper ring device and the current device, and it is determined that the intermediate link is a source of the abnormal message received by the current device receiving module and is a fault point, and a fault location message that the intermediate link device is abnormal is sent to the previous link device and the current device of the upper ring device, so that the fault location message finally reaches the protection device for alarming and sending.
C2), the operation state of the transmission module and the reception module of each link device is determined by monitoring the transmission module and the reception module of each link device by the device inside the channel or the device outside the channel. So as to find the source of the abnormal message sent by the sending module of the current equipment through the steps of C21), C22) and C23), respectively.
In step C21), when it is monitored that the sending module of the current device is abnormally operated, it is indicated that the sending module of the current device is a fault point and is a source of an abnormal message sent by the sending module of the current device. And then sending abnormal fault positioning messages sent by the current equipment to the upper ring equipment and the lower ring equipment to determine that a sending module of the current equipment is a fault point, so that the fault positioning messages finally reach a protection device for alarming and uploading.
At step C22), the principle is the same as that of step C11), and the description is omitted here.
In step C23), it is monitored that the sending module and the receiving module of the current device both operate normally, and when the message sent by the sending module of the current device is abnormal, it indicates that an abnormal condition occurs in the process from the receiving module to the sending module inside the current device, and a fault point is located in an internal link between the receiving module and the sending module of the current device, where the internal link is a source of the abnormal message sent by the sending module of the current device, and then the fault location message with the abnormal internal link of the current device is sent to the upper ring device and the lower ring device, so that the fault location message finally reaches the protection device for alarming and uploading.
Therefore, the operation states of the sending module and the receiving module of each link device can be monitored, and the fault confirmation message is exchanged with the sending source in the abnormal message state, so that the fault points of the current device, the ring mounting device and the middle link device can be positioned, and the fault points of the internal links from the sending module, the receiving module and the receiving module to the sending module can be further subdivided and judged, so that the fault points can be accurately and quickly positioned, and the fault recovery efficiency of the multiplexing channel can be improved. The judging method is realized without adding extra equipment, does not damage the original communication running state and environment, has low cost and high practicability, and is suitable for popularization and use.
When the fault point is determined, in the step D), the lower ring device only needs to forward the fault locating message downwards to achieve the protection device, and the lower ring device does not need to perform abnormal detection on the fault locating message sent by the current device in the whole process, so as to improve the subsequent reporting efficiency. And E), the protection device sends out an alarm signal in a delayed mode according to the fault positioning message to form an alarm message and the alarm message is uploaded. And the fault repairing personnel can carry out accurate repairing operation according to the alarm signal and the sent alarm message.
The above is merely an embodiment of the present invention, and is not intended to limit the present invention. Various modifications and alterations to this invention will become apparent to those skilled in the art. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention should be included in the scope of the claims of the present invention.
