Description

Self-operating device using interprocessor communication in communication system and its method {Apparatus and method for shelf operation using IPC in communication system}

The present invention relates to a self-operating device and method using interprocessor communication of a communication system, and more particularly, TCP / IP (Transmission Control Protocol / Internet Protocol) between an operating device and a self in a system performing communication between the operating device and the self. Self-operating device and method using inter-processor communication of communication system to simplify self hardware module and reduce traffic load of system by operating internal processor communication (IPC) between self It is about.

In general, a communication system for communication between stations on a network or a control system for operation control of a plurality of devices includes at least one operating device and a target device including a plurality of self devices.

Figure 1 is a block diagram of the link between the operating equipment and the self of the general communication system.

According to Figure 1, the operating equipment 110 is implemented as a server or a personal computer (PC) capable of performing a universal function, the target equipment 120 performs a specific function or perform the same function in duplicate It has a plurality of shelves for the purpose.

And the function of performing a plurality of self provided in the target equipment 120 is not the same as each other, but has the same characteristics in the communication function with the operating equipment (110). Accordingly, when the self 1 121 is described as an example among the plurality of shelves, the commercial communication chip 122 for communication with the operating device 110 is provided.

Thus, the operating device 110 and the target device 120 are connected by a local area network (LAN) to perform communication according to the TCP / IP protocol. In order to perform TCP / IP communication between devices, a communication chip must be provided for each device.

That is, the commercial communication chip 122 is mounted for each shelf and the operating device 110 performs communication according to the TCP / IP protocol for all shelves. In general, a commercial communication chip 122 is applied to the SONIC chip.

Meanwhile, the communication performance procedure according to the TCP / IP protocol in the server / client environment is as follows.

The server and client side include socket (), a socket handling function, which calls socket () on the client and issues a socket connection request with the connect () function. On the server side, the routine handles socket () → bind () → listen (). When connect () arrives from the client side, the accept () function sends a connection response.

Thus, data transmission and reception by send () and recv () routines are continued while socket connection is established between server and client side, and socket connection is released when the close () routine is processed on client side.

However, the related art described above has a disadvantage in that the cost of the configured hardware is high because each chip of the target device must have a commercial communication chip for LAN communication.

In addition, all the self and the operating equipment are connected 1: 1 to perform TCP / IP communication. Therefore, when multiple target equipments are connected and operated in one operating equipment, traffic between transmission lines is generated and the operating equipment is overloaded. There is a problem that occurs,

The present invention was created to solve the above-mentioned conventional problems, an object of the present invention is the communication between the processors between each self in connection with the TCP / IP between the operating equipment and the self in the system for performing the communication between the operating equipment and the self (Internal Processor Communication, abbreviated as IPC) to provide a self-operating device and a method using the inter-processor communication of the communication system to simplify the hardware module of the self and reduce the traffic load of the system.

It characterized in that it comprises a target equipment to enable data exchange.

Self-operating method using the inter-processor communication of the communication system of the present invention for achieving the above object, the step of making a TCP / IP connection between the master device of the operating equipment and the target device in the self-operating device using the inter-processor communication of the communication system Wow; When a TCP / IP connection is established between the operating device and the master self, the master self designating a receiving target processor to receive data, configuring a token, and sequentially transmitting the configured token to each general self; The general self that receives the token sent by the master self determines whether it is designated as a receiving target processor in the corresponding token, and if it is directed to the receiving target processor, the general self receives the corresponding data and then receives the corresponding token. Delivering to the self, and if it is not designated as the receiving target processor, characterized in that it comprises the step of delivering only the corresponding token to the master self.

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

2 is a block diagram of a self operation apparatus using interprocessor communication of a communication system according to an embodiment of the present invention, and FIG. 3 is a flowchart of a self operation method using interprocessor communication of a communication system according to an embodiment of the present invention. .

According to FIG. 2, the embodiment includes an operating device 210 implemented as a server or a PC, and a target device 220 having a plurality of shelves. Operating equipment 210 is to hold the control logic selected by the operator to perform the control operation accordingly, to change the control logic in response to changes in the operating environment of the system or the configuration of the target equipment 220, and the like. It should also be versatile, such as providing a user interface for operators to monitor the system's operational status.

And the operating equipment 210 is connected to the target equipment 220 by performing TCP / IP communication through the LAN to control the general matters regarding the operation of the system. Information regarding the TCP / IP communication protocol is known.

The target equipment 220 includes a master shelf 221 and a general shelf 224 dedicated to communication with the operating device 210. At this time, the IPC communication is performed between the master self 221 and the plurality of general self 224 of each target device 220. Since the plurality of general self 224 is the same component in terms of TCP / IP communication and IPC communication, it will be collectively referred to as self 1 of reference numeral 224.

Therefore, since TCP / IP communication of the target device 220 is performed only by the master self 221, communication between each operating device 210 and the general self 224 is performed through the master self 221. IPC communication takes place in a linked state.

In order to perform this function, the master self 221 includes a commercial communication unit 222 for TCP / IP communication, and includes an IPC communication unit 223 for IPC communication. The commercial communication unit 222 may be implemented as a commercial communication chip such as SONIC, and the IPC communication unit 223 may be implemented as an RS232 or RS422 port for serial communication between processors in each self.

In addition, the general self 224 includes an IPC communication unit 225 for IPC communication with the master self 222. The IPC communication unit 225 of the general self 224 has the same configuration as the IPC communication unit 223 of the master self 221. The IPC communication unit 225 of the general self 224 is mainly for communication with the master self 222, but communication between each general self 224 may be made depending on the application.

An embodiment of a self-operation method using inter-processor communication of a communication system applied to a self-interoperation apparatus according to such a configuration will be described as follows.

Referring to FIG. 3, the operating device 210 to control the target device 220 transmits data to the master self according to the TCP / IP protocol (S310).

Hereinafter, data refers to any signal transmitted through a corresponding communication protocol unless otherwise specified.

When the master self 221 receives the data to the commercial communication unit 222, and sends a message reception notification to the operating device 210 in accordance with the TCP / IP protocol execution procedure (S320).

IPC communication, on the other hand, is intended to provide transmission transparency when a user communicates between processors using a signal, regardless of whether the other process is within the same processor or on another processor. Interactions take place using intermediate IPC functions without using shared memory and can be used for synchronization or communication purposes. When used for communication purposes, signals with information are used.

Functions for the IPC communication include a transmission function for transmitting a signal to a counterpart processor, a reception function for transferring an arrived signal to a corresponding processor, and a signal mapping function for processing an initial signal.

So, the transmission of signal for IPC communication follows the token ring method.

The token ring type IPC communication is applied to each self communication of the target device. For convenience of description, a variable N having an integer value is set to distinguish the self that the token is delivered. When the first token transfer by the master self 221, N is set to 1 (S330).

After the step S330 is performed, the master self 221 constructs the token and data including the receiving target processor and the identifier, and transmits the token and data to the N-self self, which is the N-th self, through the IPC communication unit 223 (S340).

Then, the general self 1 (224) receives the token, checks whether it is a receiving target processor, performs a specific operation according to whether it is designated as a receiving target processor, and then transfers the corresponding token to the master self (221). Return (S350).

In step S350, the general self that receives the token, if it is not designated as the receiving target processor, returns the corresponding token as it is, and if it is designated as the receiving target, receives all data received with the corresponding token and receives the token. Return to the master self (221).

After the step S350 is performed, the master self 221 determines whether the token is returned from all general self in the target device 220 (S360).

Thus, when it is confirmed that there is a general self for which no token is returned, the master self 221 accumulates the N value by 1 and returns to step S340, whereby the general self (general self 2, general self) corresponding to the number indicated by N is returned. 3, ..., etc.) and passes the token returned in step S350 (S370).

On the other hand, if it is determined in step S360 that all tokens are returned from the general self, the master self 221 stops transmitting the corresponding token and data. In this system, IPC communication between the master self 221 and the general self 224 is performed.

According to the self-operating apparatus and the method using the interprocessor communication of the communication system of the present invention described above, one commercial communication chip on the master shelf of the target equipment for TCP / IP communication and IPC communication, each serial communication port By providing each of the self-communication between the operating equipment and the target equipment is made it is possible to reduce the system configuration cost.

In addition, in the present invention, since one TCP / IP connection is made between the target device and the target device, even when one operating device controls a plurality of target devices, the traffic load on the communication line is increased and the overload of the operating device is prevented. It has an effect that can be done.

Although the preferred embodiment of the present invention has been described above, the present invention may use various changes, modifications, and equivalents. It is clear that the present invention can be applied in the same manner by appropriately modifying the above embodiments. Therefore, the above description does not limit the scope of the following claims.
