Alarm detection and management device of signal terminal in number 7 signal processing system

The present invention relates to a number seven signal processing system (Signaling System NO. 7 Unit, hereinafter SS NO. 7 unit weak in the exchange), in particular, SS NO. 7 The present invention relates to an alarm detection and management device for alarm detection and management of a signaling terminal connected to a unit.

SS NO. 7 Unit is the NO. It is a system block that performs signal processing to send a message using 7 protocols. It is equipped with a function to detect and manage function alarms and board removal / mounting alarms for connected signal terminals. Here, the function alarm is a signal generated when a specific function performed at the signal terminal is abnormal, and the board detachment / mounting alarm is a signal generated when the signal terminal board is detached.

Conventional SS NO. 7 The alarm detection and management device provided in the unit has an alarm pressure unit and an OS (Operating System) function block to detect and manage alarms in accordance with the disconnection of the signal terminal board in real time. In the case of the function alarm, there is a problem that the detection and management structure is complicated and inefficient.

That is, the function alarm detection made in the above-described alarm detection and management device is SS NO. 7 If a function alarm occurs in at least one of the signal terminals connected to the unit (up to 16 signal terminals are connected according to the existing alarm detection system), the function alarm pressure function in the alarm Generates an interrupt signal to notify the occurrence of an alarm. The generated interrupt signal is sent to the OS function block in the processor. Accordingly, the OS function block detects the function alarm source, and provides the function alarm cause information present in the status register provided in the signal terminal which is the searched function alarm source to the user function block as the upper block. Manage status of function alarm information.

However, after the function alarm information thus detected is provided to the user function block, the function alarm pressure function unit in the alarm pressure canceling unit clears the state of the status register in the corresponding signal terminal, but the clear state is not provided to the user function block. In the user function block, it is necessary to check the status register in each signal terminal by polling method through the OS function in order to recognize the clear status of the corresponding status register. .

The present invention has been made to solve the above-described drawbacks, SS NO. It is an object of the present invention to provide an alarm detection and management device for a signal terminal that can notify a function alarm occurrence and recovery status by using an interrupt when detecting a function alarm of a signal terminal.

The above and other objects and various advantages of the present invention will become apparent from the following description of the preferred embodiment.

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

Fig. 1 is a block diagram showing the relationship between an alarm detection and management device of a signal terminal and a signal terminal in the number seven signal processing system (also referred to as SS NO. 7 unit) according to the present invention. SS NO. 7 Unit 100 is connected.

SS NO. The 7 unit 100 is connected to a processor 110 having a user function block 111 and an OS function block 112, and an interrupt generator 120 for generating an interrupt every time a function alarm is generated and recovered. Function alarm (FA) collection unit 131 for collecting function alarm generation and recovery information of the signal terminals STO to ST15, and removal / mounting alarm collecting unit 132 for collecting board removal / mounting alarm information It consists of an alarm collecting unit 130 having a).

The alarm detection and management apparatus according to the present invention configured as described above is driven as follows.

First, the alarm collection and management for the removal / mounting on the signal terminal board is performed in the same manner as the conventional signal terminal STO to the connection / attachment alarm collection function 132 provided in the alarm collection unit 130. The board detachment state for ST15) is detected, and the detected board detachment information is transmitted using the allocated 16-bit information among the 32-bit data transmitted to the OS function block 112. The OS function block unit 112 transmits the alarm information according to the board hernia to the user function block 111 to be managed by the user function block 111.

Function alarm detection and management is performed as follows.

That is, when at least one function alarm signal is transmitted from the connected signal terminals STO to ST15, the function alarm collecting function unit 131 provided in the alarm collecting unit 130 receives an error from the interrupt generator 120. Outputs the alarm information collected to generate an interrupt.

Accordingly, the OS function block 112 recognizes that a function alarm has occurred, reports that a function alarm has occurred to the user function block 11, and at the same time, the status registers STSRO provided in the signal terminals STO to ST15, respectively. Read the cause of the function alarm stored in (STSR15).

When the user function block 111 receives a message indicating that a function alarm has been generated, an alarm is generated based on the function alarm collection information contained in 32 bits transmitted from the alarm collection unit 130 held in the OS function block 112. Detects the source source, requests the OS function block 112 to receive the value of the status register of the source of the function alarm generation source among the values of the status registers STSRO to 15 stored in the OS function block 112; Manage function alarm information.

When the state register in the corresponding signal terminal is cleared by the transmission of the alarm information, the FA aggregation function unit 131 generates the alarm aggregation information so that an interrupt is generated in the interrupt generator 120 again. Accordingly, the interrupt generator 120 generates an interrupt even when the alarm is recovered, and the generated interrupt is provided to the OS function block 112.

In the OS function block 112, when the interrupt signal is received from the interrupt generator 120, the status register is cleared by analyzing the allocated 16-bit information among the 32 bits output from the alarm collector 130 in the same manner as when the function alarm is generated. The identified information and report the identified information to the user function block 111 to manage the function alarm information. Here, the OS function block 112 has a function of analyzing whether the generated interrupt is caused by a function alarm of the signal terminals STO to ST15 or when the interrupt is generated from the interrupt generator 120. .

As described above, the present invention enables the detection of a function alarm source by generating an interrupt signal at the time of function alarm occurrence and recovery at the time of function alarm detection of the signal terminal in the number seven signal processing system. By performing the report under the leadership of the user function block, the function alarm detection and management can be minimized and the function alarm can be efficiently managed by minimizing the load of the user function block for the function alarm detection and management.

Although the present invention has been described in the above-described embodiments, those skilled in the art will appreciate that various changes and modifications can be made without departing from the spirit of the present invention. Therefore, the technical scope of the present invention should not be limited to the contents described in the detailed description of the specification but should be defined by the claims.
