Description

Reliability connection detection method and system

The present invention relates to telecommunications network technologies, and more particularly to a method and system for reliable connection detection in a telecommunications network. Background technique

The telecommunication network is composed of an access layer, an aggregation layer, and a backbone layer. The access layer is responsible for accessing various types of users, including access to twisted pair access, fiber access, and wireless access. Because the access layer has many devices and user loops, the access layer is the most vulnerable to failures in the entire network, and fault location and maintenance are relatively difficult.

For example, the x-ray subscriber line (xDSL, X Digital Subscriber Line) is widely used. To ensure the normal operation of the xDSL access service, it is necessary to diagnose various types of faults that affect the service in a timely manner. Therefore, the subscriber line parameters (such as Line voltage parameters, line resistance parameters, line capacitance parameters, line background noise and line-to-ground balance, etc., as well as user terminal equipment and central office equipment (such as Digital Subscriber Line Access Multiplexer (DSLAM) ), Broadband Access Server (BRAS, Broadband Remote Access Server), Dynamic Host Configuration Protocol (DHCP) server, etc. Based on these measurement data, you can understand the operation of the line, user terminal, and central office equipment in a timely manner, and locate faults that affect service operations in time to fix the faults in time.

In response to this problem, a solution has been proposed in the prior art, that is, by means of a test access system, such as a Test Access Matrix (AMM) or an Automatic Main Distribution Frame (AMDF). , Users without test bus are connected to the test system. At present, there are two main ways to connect devices to the test system based on the test access system: centralized access and distributed access. For centralized access, the reliability of test access can be guaranteed due to the connection of dedicated connectors. Figure 1 is a schematic diagram of the connection mode of the existing distributed test access system. The system includes a test system, a test access system, a distribution frame (MDF, Main Distribution Frame), a terminal device, and a central office device. The test access system is connected to the test system and the MDF, and the terminal device and the central office device are connected to the MDF through the external line and the internal line, respectively. The test access system connects the terminal device and the central office device to the test system through the connection with the MDF for subsequent testing. But by The users that are connected are distributed on different MDF modules. In this way, in actual use, installation, and routine maintenance, the test access system and some ports of the MDF module cannot be reliably connected, which leads to this part. The user corresponding to the port cannot be covered by the test system, which affects the availability of the test system, and even causes the user to fail to conduct business normally. Therefore, it is necessary to be able to detect in time that the test access system and the MDF have no reliable connection ports, so as to avoid the above problems through remedial measures. Summary of the invention

The embodiment of the invention provides a reliable connection detection method, which can conveniently and timely detect whether the test access system and the module to be detected are reliably connected.

The embodiment of the invention simultaneously provides a reliability connection detection system, which can conveniently and timely detect whether the test access system and the module to be detected are reliably connected.

The technical solution of the embodiment of the present invention is implemented as follows:

A reliability connection detection method, the method comprising:

The test access system acquires and stores the connection state information of the test access system and the module to be detected according to the connection state of the detection line in the golden finger, and the connection state includes a reliable connection and an unreliable connection;

A reliability connection detection system, the system comprising:

Testing the access system, the test access system includes a golden finger, and a detection line is disposed in the gold finger in advance for insertion into a module to be detected on the user side, and according to the detection line in the golden finger a connection state, obtaining and saving connection state information of the module to be detected, the connection state including a reliable connection and an unreliable connection;

And a test system, configured to obtain connection state information of the test access system and the to-be-detected module from the test access system, and analyze the connection result according to the connection state information.

It can be seen that, according to the technical solution of the embodiment of the present invention, since the detection line is set in the golden finger of the test access system in advance, when the test access system is inserted into the module to be detected on the user side, the The connection status automatically knows the connection status between itself and the module to be detected, that is, whether the connection is reliable. Further, the test system obtains the connection between the test access system and the module to be tested from the test access system.

FIG. 2 is a schematic structural diagram of a reliability connection detection system. As shown in FIG. 2, the system includes a test system, a test access system, a modem (indicating a terminal device), a DSLAM (representing a central office device), and an MDF, wherein each component is connected as shown in FIG. The system is the same; the test access system further includes a main controller and an access module. Specifically, the test access system is connected to the test system through the main controller, and is connected to the MDF through each access module, that is, the test access system is inserted into the MDF through the golden finger in the access module.

The test system controls each access module to activate the Modem and the DSLAM port on the user side through the main controller; each access module exchanges information with the MDF, and learns whether the ports of the MDF are reliably connected according to the information status of the MDF feedback, if feedback If the information is normal, it means a reliable connection. If the feedback is an error message, it means an unreliable connection, and the obtained result is fed back to the main controller; the main controller further sends the feedback result received from each access module to Test system; the test system analyzes the results and knows the connection between the current test access system and the MDF.

However, the system has certain drawbacks: First, due to the modem and DSLAM ports The activation of the line takes a long time, and the test system can only perform activation detection on one user at a time. Therefore, when there are many users in the system, it takes a long time to perform activation detection for each user separately, and the overall work efficiency is very high. In addition, the detection system needs to implement the detection of the user, and the user line and the DSLAM port need to be connected to the test system, so that the user is interrupted by the ongoing business, such as the Internet service and the telephone service, thereby affecting User satisfaction; However, if you want to avoid the user's business interruption, you need to make a choice in the detection time, but when the user goes online or on the phone, there is no law to follow, so it is difficult to determine the detection time, which leads to the connection. Unreliable problems cannot be discovered in time, affecting the normal operation of subsequent operations. In addition, when the Modem is not working or there is a fault, the Modem cannot be detected.

FIG. 3 is a schematic structural diagram of another reliability connection detection system. As shown in FIG. 3, the system includes a test system, a test access system, a Modern, a DSLAM, and an MDF, wherein each component is connected in the same manner as the system shown in FIG. 1; the test access system further includes an access module.

In the system shown in Figure 3, the connection status between the access module and the MDF ports is detected by a manual method using a dedicated instrument such as a multimeter, so as to know whether the MDF and the test access system are reliably connected.

However, the system also has certain defects: First, the detection system requires the staff to go to the test site and use special instruments for testing, the detection cost is high, and the skill requirements of the staff are relatively high; secondly, usually, An MDF includes multiple ports, and each port corresponds to one user. Then, the detection system requires the staff to test the user lines corresponding to each port one by one, and the workload and work intensity are relatively large, which takes a long time. And the efficiency is low; further, the detection system may interrupt the user's ongoing business due to the operation, and reduce the user's satisfaction; Finally, when the detection is required, the staff member is required to arrive at the test site for processing, so the detection system Similarly, unreliable connections cannot be detected in time, which affects the normal operation of subsequent services.

It can be seen that although the above technical solution provides a solution for detecting whether the test access system and the MDF are reliably connected, since there are different degrees of defects, the ports that are not reliably connected can not be detected in time, thereby causing the ports. The corresponding user cannot be covered by the test system, and the user service corresponding to the part of the port cannot be used normally.

For the above problem, the solution in the embodiment of the present invention passes the test access system to connect the user without the test bus to the test system, and then tests the part of the user, that is, the system shown in FIG. 1; The solution can conveniently and timely detect the test access system and the mode to be tested Whether the blocks are reliable connections, and corresponding measures are taken according to the detection results, thereby avoiding the failure to detect the ports of the unreliable connection in time in the prior art, so that the users corresponding to the ports cannot be covered by the test system, and further The problem that the user service corresponding to this part of the port cannot be used normally.

The present invention will be further described in detail below with reference to the drawings and embodiments.

In the embodiment of the present invention, the detection line is set in the golden finger of the test access system in advance; when the reliability connection detection is required, the test access system is inserted into the module to be detected on the user side; the test access system According to the connection state of the detection line in the gold finger, the connection state information of the module to be detected is obtained and saved, and the connection state includes a reliable connection and an unreliable connection; the test system acquires the test access system from the test access system and waits The connection status information of the module is detected, and the detection result is obtained through analysis.

Among them, the gold finger refers to the use of the metal plating of the printed circuit board as a connecting unit, in order to increase the adhesion of the conductor portion and the reliability of the contact, reduce the contact loss, etc., and increase the gold plating layer in the connected conductor portion; The shape is similar to the shape of a finger, so it is called a gold finger.

4 is a flow chart of an embodiment of a method of the present invention. It is assumed that the module to be detected in this embodiment is an MDF. Of course, it can also be other modules having similar functions to the MDF, such as a computer peripheral component expansion interface (PCI) slot. Then, as shown in FIG. 4, the embodiment includes the following steps:

Step 401: Insert the test access system into the MDF on the user side.

In this step, the test access system is inserted into the MDF of the user side by testing the access module in the access system. The access modules mentioned here may be one or more, depending on the number of MDFs in the actual application environment. Generally, the number of access modules is the same as the number of MDFs.

Step 402: The test access system automatically acquires and saves the connection state information of itself and the MDF. The connection status includes a reliable connection and an unreliable connection. The method for testing the access system to obtain its own connection status information with the MDF includes: setting a detection line in advance at a specified position in all or a specified part of the golden finger of the access module.

The specific setting method may be: setting a detection line on the outermost layer of the gold finger, the detection line may be a normal copper line, and further improving the contact performance, and performing gold plating treatment on the outside; the length of each detection line Generally, it is set to be equal to the length of the gold finger; the specific number of detection lines set in each gold finger is not specifically required, and is assumed to be set to two in the embodiment of the present invention; when the access module is inserted into the MDF, if each part of the MDF The metal piece of the port will detect all the two fingers on the gold finger with the detection line. If the lines are connected together, the test access system and the MDF are connected reliably; otherwise, the test access system and the MDF are considered to be unreliable as long as the two detection lines of any one of the golden fingers are not connected. The number of gold fingers included in the access module is the same as the number of ports included in the MDF.

For example, the detection lines are set in the three gold fingers A, B, and C of the access module in advance; wherein the gold finger A is provided with detection lines A1 and A2, and the gold finger B is provided with detection lines B1 and B2, and the gold finger C is provided with detection lines C1, C2; when the access module is inserted into the MDF, if the metal pieces in the port corresponding to the gold fingers A, B, C will be A1 and A2, B1 and B2, C1 and C2, respectively Connected together, the test access system is connected to the MDF reliably; otherwise, as long as A1 and A2, B1 and B2, or any pair of C1 and C2 are not connected, the test access system and MDF are Unreliable connection.

Step 403: The test system obtains the connection state information of the test access system and the MDF from the test access system, and obtains the detection result through analysis.

In this step, the test system obtains the connection state information of the test access system and the MDF. The test system may actively test the access system to read, or the test access system may report the test system to the test system.

In the subsequent process, the test system can read the connection status information of the access system and the MDF at any time or periodically; or, when the connection state between the test access system and the MDF changes, the test access system actively changes the information. · ^ Give the test system.

Based on the above method, FIG. 5 is a schematic structural diagram of a system embodiment of the present invention. It is also assumed in this embodiment that the module to be detected is an MDF. As shown in FIG. 5, the system mainly includes a test system 502 and a test access system 501. The test access system 501 includes a gold finger, and a detection line is preset in the gold finger.

The test access system 501 is configured to be inserted into the MDF of the user side, and obtain connection state information of the connection with the MDF according to the connection state of the detection line in the golden finger, such as a reliable connection and an unreliable connection; the test system 502 is configured to The connection state information of the test access system 501 and the MDF is obtained from the test access system 501, and the detection result is obtained through analysis.

The test system 502 can be further configured to read the connection status information of the test access system 501 and the MDF at any time or periodically.

The test access system 501 can be further configured to: when the connection state between itself and the MDF changes, Reported to the test system 502 in time.

The system shown in Figure 5 will be further described in detail below by means of a preferred embodiment:

Figure 6 is a schematic view showing the structure of a first preferred embodiment of the system of the present invention. As shown in FIG. 6, the test access system 501 in this embodiment specifically includes an access control module 601 and a distributed access unit 602. The distributed access unit 602 further includes an access module 6021 and a diagnostic module. 6022 and a control module 6023.

It should be noted that, in practical applications, the distributed access unit 602 included in the test access system 501 may be one or more, and in many cases, multiple, but the functions of the distributed access units are the same. Therefore, in the present embodiment, for convenience of description, only one example will be described.

The workflow of the system embodiment includes:

The golden fingers in the access module 6021 in the distributed access unit 602 are set in advance, that is, two detection lines are set. As shown in FIG. 7, FIG. 7 is a schematic diagram of a detection line set in a gold finger according to an embodiment of the present invention, wherein the detection line A and the detection line B are two detection lines provided. The setting manner may be that all the golden fingers in the access module 6021 are set, or only some golden fingers are set, for example, only the golden finger at the edge portion of the access module 6021 is set, because usually Unreliable connections are caused by edges. Therefore, in practical applications, only the connection at the edge can be detected, and the connection in the default middle portion is a reliable connection. In the setting of the gold finger, you can set only the front side, or you can set only the reverse side, or both the front and back.

When the reliability connection detection is required, the access module 6021 in the distributed access unit 602 is inserted into the MDF of the user side, specifically, the golden finger in the access module 6021 is inserted into the MDF, and the gold is inserted into the MDF. The number of the fingers is the same as the number of ports included in the MDF, that is, the corresponding golden fingers in the access module 6021 are inserted into the respective ports in the MDF;

After the gold finger is inserted into the MDF port, if it is connected reliably, the metal piece inside the MDF port will connect the two detection lines on the gold finger. If there is no reliable connection, the two detections on the gold finger Lines will not be connected together;

The diagnosis module 6022 is connected to the access module 6021, and monitors the connection of the gold fingers each having the detection line in the access module 6021. If two detection lines of all the gold fingers provided with the detection lines are respectively connected together Then, the diagnostic module 6022 changes the state of the self-detection circuit; if not all, even if only one detection line of the gold finger with the detection line is not connected, the diagnostic module 6022 does not change the state of the self-detection circuit; The way in which the state of the detection circuit is changed Can be: set a level value in the detection circuit, when all the two detection lines of the gold finger provided with the detection line are respectively connected together, the level value is set to 1, otherwise, set to 0;

If the test system 502 and the test access system 501 are powered on when the access module 6021 is inserted into the MDF, the test system 502 can control the control module 6023 to obtain the detection circuit in the diagnostic module 6022 through the access control module 601. After the control module 6023 reads the detection circuit status information in the diagnosis module 6022, it reports to the test system 502 through the access control module 601. Alternatively, the diagnosis module 6022 actively tests the control module 6023 and the access control module 601. The system 502 reports its own detection circuit status information;

If the test system 502 and the test access system 501 are not powered when the access module 6021 is inserted into the MDF, then when the test system 502 and the test access system 501 are powered up for the first time, the test system 502 can be accessed. The control module 601 controls the control module 6023 to read the detection circuit status information in the diagnosis module 6022; the control module 6023 reads the detection circuit status information in the diagnosis module 6022, and reports it to the test system 502 through the access control module 601; or The diagnosis module 6022 actively reports its detection circuit status information to the test system 502 through the control module 6023 and the access control module 601;

The test system 502 analyzes the received detection circuit status information, for example, according to the detection circuit status information, whether the current test access system 501 and the MDF are reliably connected. If the user side includes multiple MDFs, the test connection needs to be further determined. In which case, the MDF is connected to the MDF, and the MDF is connected to the MDF. In this case, the detection circuit status information received by the test system 502 further includes the ID of the corresponding MDF.

In the foregoing embodiment, the serial access interface, such as RS485, RS422, RS232, or IP network, such as 10M, 100M, etc., may be used between the distributed access unit 602 and the upper control module, that is, the access control module 601 and the test system 502. Communicate.

Figure 8 is a schematic view showing the structure of a second preferred embodiment of the system of the present invention. As shown in FIG. 8, the test access system 501 in the embodiment, that is, the distributed access module 501 specifically includes a control diagnostic module 801 and one or more access modules 802.

Compared with the embodiment shown in FIG. 6, the embodiment integrates the plurality of distributed access units 602 shown in FIG. 6 into one distributed access module 501, and the access control module 601 in FIG. The control module 6023 and the diagnostic module 6022 are integrated into a control diagnostic module 801.

Correspondingly, the control diagnosis module 801 in this embodiment is used according to the setting in the access module 802. The connection state of the gold finger provided with the detection line sets the state of the self-detection circuit, that is, if the metal pieces of each port in the MDF connect the two detection lines set on the respective gold fingers, respectively, the control diagnosis module 801 changes itself. The state of the circuit is detected. Otherwise, the state of the self-detection circuit is maintained, and the state of the detection circuit is reported to the test system 502 actively or under the control of the test system 502.

It can be seen that, by adopting the technical solution of the embodiment of the present invention, the test access system can automatically obtain the connection state information of the module and the module to be detected, that is, whether the connection is reliable, and further, the test system obtains the test access system from the test access system. The connection status information of the module is detected, and the detection result is obtained after analysis. Compared with the prior art, the solution in the embodiment of the present invention can not only detect whether the test access system and the module to be detected are reliably connected in time, but also does not need to interrupt the original service of the user during the detection process, thereby improving user satisfaction. Furthermore, the automatic detection method provided by the embodiment of the present invention improves the detection efficiency and reduces the detection cost compared to the prior art.

Through the description of the above embodiments, those skilled in the art can clearly understand that the present invention can be implemented by means of software plus a necessary hardware platform, and of course, can also be implemented entirely by hardware.
