Description

Automatic ID Assignment Device and Method of Stacking System

The present invention relates to an apparatus and method for automatically designating an ID of a stacking system, and more particularly, to an apparatus and method for automatically assigning each unique ID in a system requiring stacking such as network equipment.

When stacking multiple systems in parallel or serially, it is necessary to assign unique IDs to each other.In the case of exchanging information with each other according to the ID given to each of them, from whom or to whom? There are a lot of systems that detect / analyze the information to go and perform the function operation accordingly. In particular, systems that function properly only by providing system management functions, maintenance functions, and stacking configuration information are widely applied to computers, exchanges, and short-range communication equipment.

Accordingly, the present invention continuously assigns unique IDs between such systems, and aims to enable smooth system configuration and operation with unique IDs unless power is supplied to each system.

As with the conventional method, the setting method using a dip switch method or jumper pins, which are independent setting mechanisms for each system, seems to be very simple, but it is expensive in actual maintenance or management. For example, the dip switch method assigns a number to each cascaded system individually. Therefore, inside the system a number is given by this setting, and this number is used as a unique ID. The same applies to the jumper pin method.

In the related art, when an installer sets a unique ID for each device, duplicate or missing IDs may occur. If a worker's mistake occurs and there is no mechanism for finding it easily, there is a drawback of investing time and money in recovery. In addition, when removing a failed system and replacing it with a new system, it is inconvenient to check the previous ID and give the same ID. In addition, the manual work requires confirmation procedures for replacement and reconfiguration, and in some cases, there is a problem that potential factors may occur repeatedly.

When mechanically setting the system ID as shown in FIG. 1, there is inconvenience that one must work by hand one by one. For example, in FIG. 3, if the current system ID is set to '0', all switches must be 'on' to '0', and if the next system ID is set to '1', myid0_ is switched 'off' and the remaining myid1_, myid2_ must be set to '1' by 'on' the switch. In other words, it is inconvenient to give each ID.

Accordingly, an object of the present invention is to provide a device and method for automatic ID designation of a stacking system, which has been devised to solve the above problems.

One preferred embodiment of the automatic ID designation device of the stacking system according to the present invention created to achieve the above object,

ID recognizer of the current (current system);

ID generator of the following systems;

Input connector; And

It includes an output connector.

In the present invention, it is preferable that the signals myid0_, myid1_, and myid2_ which are all 'low' active signals are input through the input connector.

Preferably, the input signal is pulled up inside the input connector to be a signal stk0_, stk1_, stk2_,

The stk0_, stk1_, and stk2_ signals are input to a recognizer for recognizing the ID number of the current system, and then it is preferable to determine the ID of the current system.

Preferably, the stk0_, stk1_, and stk2_ create an ID of the next system by increasing the ID number of the current system by '1' through the next system ID generator.

In order to determine the ID of the current system, it may be inverted and used as a 'high' active signal, or stored in a register to use an output signal, and when stored in a register, the microprocessor may read it. desirable,

In the case of using the register, it is preferable to make an output enable signal for decoder logic and a read externally.

If you want to modify it as needed internally, it is desirable to be able to adjust it through the current system ID number recognizer.

In order to make the ID of the next system, it is preferable that stk0_ becomes nextid0_ via inverter G0 and becomes myid0_ of the next system through the output connector,

nextid1_ is created through exclusive oaring (G1: Exclusive OR gate) of stkid0_ and stk1_, and nextid2_ satisfies stkid0_ and stk1_ at the same time (G2: AND gate) condition and stk2_ is exclusive oaring ( G3: Exclusive OR gate) is preferable.

One preferred embodiment of the automatic ID designation method of the stacking system according to the present invention for achieving the above another object,

Creating an ID of the next system by increasing '1' to its ID in system # 0;

Entering the ID of the next system created in the above process into the input connector of the system # 1 through the output connector;

System # 1 is the process of using the ID of the next system created in the previous system as its own ID; And

Repeatedly includes the process of adding the '1' to their ID to exit the output connector.

In the present invention, it is preferable to automatically assign IDs to all systems by repeating the above process.

It is preferable that a signal entered through the input connector is processed unconditionally by its own ID.

If all the inputs are 'low', the ID is '0', so the actual use is sometimes inverted, and it is desirable to use a register to store the signal so that it can be read from the microprocessor.

It is desirable to install a dip switch in each system.

Hereinafter, the operation principle of the present invention with reference to the accompanying drawings in detail as follows.

First, Figure 2 shows a stacked arrangement as the main block diagram of the device according to the invention. As shown in FIG. 2, stacking is a function of connecting multiple systems such as separate independent device systems # 0 and system # 1 to operate as one integrated system. Therefore, each system operates with a dedicated protocol, and it is possible to communicate with each other by transmitting and receiving appropriate information according to a system ID, which is physically assigned to each unique number.

In the present invention, a function for automatically assigning an ID to a stacking method is provided in hardware.

Referring to FIG. 2, a signal input through an input connector is unconditionally processed by its ID. In other words, if the input signal level corresponds to its own ID, but the inputs are all 'low', the ID corresponds to '0' and the actual use is sometimes inverted, and the signal is stored using a register to read from the microprocessor. It also makes it possible.

System # 0 has a circuit that generates and provides the ID of the next system in the chain, and this function is the main part of the present invention. In system # 0, the ID of the next system is increased by adding '1' to its own ID. If the system enters the input connector of system # 1 through the output connector, the system # 1 uses this as its own ID and repeats the ID of its own. Add '1' again to get to the output connector. By repeating this, all systems can be automatically assigned an ID. As in the prior art, there is no need to set a dip switch in each system to set each setting.

3 is a description of a detailed circuit corresponding to the present invention. When the signals myid0_, myid1_, and myid2_ (all of them are 'low' active signals) are input through the input connector, they are pulled up internally and become signals stk0_, stk1_, and stk2_, which are input to the recognizer to recognize them as ID numbers of the current system. It can be inverted as needed to make it a 'high' active signal, or it can be stored in a register to use an output signal, or when stored as a register, to be read by the microprocessor. When used as a register, an external enable enable signal must be created for the decoder logic and readout.

In this way, the ID of the current system is determined. When receiving the input signals myid0_, myid1_, and myid2_ from 0 to 7, as shown in the timing chart of FIG. 4, the level values of these signals are used as they are, and sysid0_, sysid1_, sysid2_ is the ID of the current system. However, if you want to modify it as needed internally, you can adjust it through the current system ID number recognizer.

On the other hand, stk0_, stk1_ and stk2_ create the next system ID by increasing the ID number of the current system by '1' through the next system ID generator. That is, stk0_ becomes nextid0_ through the inverter G0 and becomes myid0_ of the next system through the output connector. Nextid1_ is generated through an exclusive O-ring (G1: Exclusive OR gate) of stkid0_ and stk1_. Finally, nextid2_ is created by satisfying both stkid0_ and stk1_ (G2: AND gate) and stk2_ through exclusive Oaring (G3: Exclusive OR gate).

As shown in FIG. 4, when the current system ID is assigned from '0' to '7', the next system ID number is assigned from '1' to '0'.

However, since the ID number is assigned from '0' to '7' because the circuit is decoded through only three input signals, the ID generator of the next system must be changed accordingly when the stacking configuration becomes large. However, the basic principle is that it adds '1' to the ID number of the current system to generate the ID number of the next system. It is emphasized that the present invention is very convenient when using the above-mentioned logic in comparison with the conventional method. .

The present invention operating as described above has an effect of reducing mistakes and hassles because each system ID is automatically uniquely assigned to each system when the system is designed through an electronic circuit.
