Description

Upload / download linkage method between control panels in synchronous line distribution device

The present invention relates to a field that can be implemented in a control block of circuit distribution apparatuses applied to a synchronous transmission network, and more particularly, to a method for interworking message upload / download between control panels in a synchronous circuit distribution apparatus.

In a general synchronous transmission network, a circuit distribution device is equipped with a control software in a unit equipped with a microprocessor for effective control and management of device maintenance and monitoring. These control processors are divided by function to control the signal processing units in the corresponding shelf, and the collected information is reported to the centralized unit that manages the maintenance of the entire device for system-level maintenance management. With the development of the synchronous transmission device represented by large capacity, intelligence, etc., dozens of control units exist in the device, and the interworking between the control processors in the device becomes an important problem. Although communication between processors is implemented by applying a commercial communication protocol, an algorithm for reinitialization and interworking relationship due to mounting and dismounting of control units is required.

Thanks to the development of optical communication technology, the line distribution device for synchronous transmission has been able to achieve high speed and high capacity of information transmission capability. It is evolving into an intelligent device that is mounted and controlled by a multiprocessor.

However, at the time of initial device initialization or when the control panels (units) are dismounted, the upload / download relationship of information for interworking has not been established. In other words, the existing technology starts the drive with a value set at the initial installation of the device, and when the control panel is mounted or unmounted, the terminal attaches terminals to each other and inputs the setting information arbitrarily. There is a problem that could not be an automated control device.

The present invention collects all of this information and collects all of this information and manages the device by function or signal object. If the unmanned station operation is required due to the complexity of the transmission network and the transmission network is complicated, the synchronous line distribution device for the reboot or reset of the device by the failure cause the upload / download interworking method between the control panels. There is a purpose.

1 is a linkage message upload / download linkage relationship between the control panel according to the present invention,

2a and 2b is a flow chart of the initialization and upload / download of the centralized control panel,

3 is a flowchart illustrating an initialization process and an upload / download process of a lower control panel.

In order to achieve the above object, the present invention provides a method for interworking message upload / download operation of a centralized control panel in a user access device, a centralized control panel, and a lower control panel in a line distribution apparatus of a synchronous transmission network, wherein the centralized control panel is the first. A first process of searching for real and hernia of all lower control panel boards in the initial initialization mode or initializing mode by switching the centralized control panel by searching whether it is an initializing process, and after searching for the real and hernia, received from the lower control panel board After the message is processed and downloaded to the lower control panel board, the second process of self-initialization termination report is reported to the user access device, and the centralized control panel is searched for the first initialization process and the user access device is received from the user access device until the download message is received. User log by processing received message Receiving the third process of uploading to the client, and receiving the download message, and after recognizing that the centralized control panel has been initialized for the first time, terminates the initialization process, and performs the process of processing the message received from the user access device in the normal state again. It is characterized by consisting of a fourth process.

Another feature of the present invention, in the interlocking message upload / download interworking method of the lower control panel in the user connection device, the centralized control panel and the lower control panel in the line distribution apparatus of the synchronous transmission network, the initialization in the lower control panel to perform the transmission and reception of messages A second process of reporting a lower control panel self-initialization termination message to the centralized control panel, and performing the lower control panel itself independent operation mode if there is no response from the centralized control panel which has received the report; A third process of performing the integrated control panel interlocking operation mode; and a fourth process of monitoring the state of each board and reporting it to the centralized control panel when there is a change after the operation of each operation mode, and entering the normal state and ending the initialization. Characterized in that consisting of.

Therefore, the present invention downloads the setting information for driving the lower signaling device from the centralized control panel when the lower control panel is mounted, and when the centralized control panel is mounted, the overall control of the device is temporarily stopped and the necessary setting information is lowered. Download it back to the control panel. When a user access device is newly connected, the maintenance management information of the device is uploaded from the centralized control panel that has all the management information of the device.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

In the configuration of the initialization unit of the present invention, the interlocking relationship with the centralized panel according to the mounting and reinitialization of each sub-control panel, the interlocking relationship between the mounting and re-initialization of the centralized panel, and the interworking according to the re-initialization of the user access device Consider the relationship and use the following method.

1 is an interlock message upload / download interlock relationship between the control panel according to the present invention. This relationship is largely related to the message flow when the centralized control panel is mounted or unloaded, the message flow when the centralized control panel is disconnected from the user access device, and the message flow when the lower control panel is mounted. Explain separately.

First, the message flow according to the mounting and switching of the centralized control panel 2 is as follows.

When the centralized control panel 2 is mounted, the lower control panel 3 requests the current status information 13, and the lower control panels 3 report the current status information of each board to the centralized control panel 2 (14). It sends its current status information report end message (15). Accordingly, the centralized control panel 2 receives the current status information report end message 15 and then transmits device information 16 to be downloaded corresponding to each function by the lower control panel 3. In this way, after the mutual information is shared between the centralized control panel 2 and the lower control panel 3, the user access point 1 is initialized.

In addition, the centralized control panel 2 transmits the self-initialization end report message 17 to the user access device 1 so that the centralized control panel 2 transmits and receives a message in the same manner as the lower control panel, and then mounts the centralized control panel. End message delivery accordingly. Its message flow is the message flow from 13 to 22 in FIG.

Secondly, the message flow according to the reconnection after losing the connection between the centralized control panel 2 and the user access device 1 is as follows.

Due to an abnormal state of the user interface 1 or an abnormal state of a local area network (LAN) between the user interface 1 and the centralized control panel 2, communication between the user interface and the centralized control panel may be interrupted and then reconnected. At this time, first, the current data request message 18 is transmitted from the user access device 1 to the centralized control panel 2, and the reference numerals 18 to 22 between the centralized control panels are sequentially performed to return to the normal state.

Third, the flow of reference numerals 12 to 16 at the time of mounting and dismounting of the lower control panel will be described.

What is important when mounting the lower control panel is to determine whether the current device is operating when the lower processor board is mounted. To do this, the device operates and performs the initialization routine for the first time and waits for the central control panel to respond. If there is no response, the controller enters the independent control mode itself. If there is a response, the device enters the centralized control panel interlocking operation mode. Whether it is in a state or remounted during operation of the device. Upon completion of initialization of the lower control panel 3 (initialization of basic control registers and variables, initial communication between the processor boards, and checking of the failure of the hardware board to be controlled and the status of each board, etc.), the self-initialization termination message 12 is sent. After transmitting to the centralized control panel and receiving the current status information request message 13 from the centralized control panel 2, the current status information report message 14 is sent to the centralized control panel after the current status information of each board is summarized. do. The contents of the current status information message sent to the central control panel include switching, signal threshold information, alarms, performance, and board mounting information. In order to finish reporting of the initialization information to the centralized control panel, the current status information report end message 15 is transmitted, and the download information (system installation initialization information, threshold value, performance monitoring target signal setting information, configuration related information, etc.) is received from the centralized control panel. 16), it configures and controls its own set values and control boards based on this information.

FIG. 2A is a flowchart illustrating an initialization process and upload / download process of the centralized control panel, and FIG. 2B is a partial detailed flowchart of FIG. 2A.

The centralized control panel is in charge of the control of the initialization process of the device. That is, the centralized control panel itself is initialized as well as the installation-related data and management data is downloaded to the re-installed lower control panel, or the installation-related data and management data are uploaded in the event of a failure of the operating user access device. The centralized control panel self-initialization is divided into the initial initialization mode by the initial installation of the rack and the initial mode by switching the central control panel. The classification of the initialization mode is performed by initially reading an address already assigned to an arbitrary area of the nonvolatile memory and searching whether the centralized control panel is the initial initialization process (hereinafter referred to as 'find centralized control panel initial initialization process').

In the initial initialization mode, the centralized control panel initially detects whether the initialization process is performed (30), and initializes the relevant table and waits for a time of about 10 seconds (40, 50). After searching (61) the thread and hernia of the lower control panel (hereinafter referred to as 'xxx'), initialize the xxx board if it is mounted (61, 62), and set xxx board initialization if it is hernia (61, 63). (This represents the real and hernia search routine of the xxx board shown in Figure 2b).

After receiving the self-initialization termination message from the xxx board (81), it requests the current status information from the xxx board (82), receives the current status information report termination message from the xxx board (84), and sets the xxx board initialization. And download to the xxx board (16 or 22 related message in FIG. 1, 86) (which represents the message processing routine received from the lower processor shown in FIG. 2B). Then, if all xxx board initialization is in the set state, the self-initialization termination report 90 is reported to the user access device, and after receiving the download information from the user access device, after recognizing that the centralized control panel is initialized for the first time, the initialization process is terminated. .

On the other hand, if the initialization of the centralized control panel for the initial process of the centralized control panel (30), if the initialization mode by the switching of the centralized control panel, all the real and hernia of the xxx is searched (61), and if the mounting state initializes (clear) the xxx board initialization (62) If the hernia status is set, xxx board initialization is set (63). Thereafter, only the board whose xxx board initialization is in the initial state is requested to present status information to the lower control panel xxx (70). Then, after receiving (84) the current status information report end message from the xxx board, setting the xxx board initialization (85), and downloading to the xxx board (16 or 22 related message of FIG. 1, 86) ( A message processing routine received from the subprocessor shown in FIG. 2B). Once all xxx board initialization has been configured, the initialization process ends. On the other hand, upon receiving the self-initialization termination report message from the xxx board in the normal state, it requests the current status information from the xxx board, initializes the xxx board initialization, and sets the xxx board initialization after receiving the termination of the current status information report from the xxx board. And download it to the xxx board.

After performing the message processing routine 80 received from the lower control panel (lower processor) described above, that is, if all xxx board initialization is in the set state, the self-initialization termination report 90 is reported to the user access device.

Then, it is searched whether the centralized control panel initialization process (100).

As a result of this search, in the initial initialization process, the message processing routines 110 and 130 received from the user access device are performed until the download message is received. The routine 110 is described with reference to FIG. 2B. First, when the current state information request is received from the user access device 111 in the normal state, the current state information report of the centralized control panel is reported to the user access device (shown in FIG. 1). And the end of the upload 112 by transmitting the current status information report end).

3 is a flowchart illustrating an initialization process and an upload / download process of a lower control panel according to the present invention.

First, by initializing the basic control register and the variable of the lower control panel (200), it is possible to transmit and receive communication-related messages between the processors. In addition, after checking the boards of the board under control, the hardware failure status information of each board is generated based on the hardware information.

Then, the lower control panel self initialization termination message (reference numeral '12' of FIG. 1) is transmitted to the centralized control panel (210).

In response to the initialization termination, the self-initialization termination message is transmitted to the centralized control panel (210), and waits for 3 seconds for a response thereof from the centralized control panel, and then determines whether there is a response (220).

If there is no response by the determination 220, the lower control panel itself operates in an independent operation mode. In its independent operation mode, communication between processors is lost, so it operates without sending or receiving messages. That is, if there is no response, if it is determined that the original mode state (backup state check) 230 is not correct, it is determined 240 as the initial start of the lower control panel, and the board setting is initialized to the default value, and the state of each board is determined. In addition, if it is determined that the original mode 230 is normal, it is determined to be remounted or reinitialized during system operation 250 to perform interrupt deactivation, maintain the current state, and determine the state of each board.

In addition, if there is a response by the determination 220, it is determined as the centralized control panel interlocking operation mode and receives a current status information request message (reference numeral '13' in FIG. 1) from the centralized control panel (260), each board. The current state information is summarized and the current state information report message ('14' of FIG. 1) is transmitted to the central control panel (270). Then, in order to finish reporting the initialization information to the centralized control panel, a current status information report end message 15 is transmitted (280). Thereafter, when receiving the download information (reference numeral '16' of FIG. 1) from the centralized control panel, based on this information, the control information of each board is reset (290).

After performing the process in the independent control mode of the lower control panel and the centralized control panel interlocking operation mode, the alarm status is monitored for each signal, and if there is a change, it is reported to the central control panel and entered the normal state. (300). Then, initialization is terminated (310).

When applying the upload / download interworking method between the control panel of the present invention as described above in the prior art to reduce the enormous time and manpower consumption, such as turning off the entire device and re-drive or set-up in each terminal, and automated re-initialization and linkage Make it possible.

The interlocking message upload / download interworking method between the control panels of the present invention as described above is an automated interlocking method, and does not affect the device signal service upon rebooting or resetting the device due to a failure and is continuously performed without manual intervention by the user. Work is possible.
