Description

Description: TECHNICAL FIELD The present invention relates to a unit setting management device of an electronic device in which a plurality of units are inserted to form a device. BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for setting or controlling operation of a unit inserted in an apparatus from a central processing unit, and an apparatus for backing up the setting of the unit from the central processing unit when the central processing unit is inserted or removed or replaced.

〔Overview〕

According to the present invention, in a unit setting management device for performing operation setting and operation control setting of a unit that constitutes a device from a central processing unit, operation setting and control contents are stored in each unit, and the central processing unit is inserted or removed or replaced. At this time, this memory content is copied to the central processing unit to perform operation setting and operation control, thereby simplifying the unit setting processing from the central processing unit.

[Conventional technology]

Conventionally, in an electronic device including a central processing unit and a plurality of units, when the central processing unit needs to be inserted or removed or replaced, after inserting the central processing unit, the operation setting contents of each unit of the entire device and It was necessary to give operation control contents to the central processing unit from the outside of the device and reset the settings.

For example, in a subscriber line carrier device in which a plurality of channel device units are inserted, the protocol depending on the signal type or the communication control method of the subscriber line processed by the channel device units, and the value of the equalizer or attenuator, etc. It is necessary to set the operation settings and operation control contents again from the outside through the central processing unit.

[Problems to be solved by the invention]

In the setting management method described above, in which the operation settings and operation control contents of each unit of the device are reset after the insertion of the conventional central processing unit, the device management and the firmware of the central processing unit are upgraded each time. Since it is necessary to provide the setting contents from the outside, there is a drawback that the setting process increases and becomes complicated.

The present invention solves the above-mentioned drawbacks, and an object of the present invention is to provide a setting management device capable of simplifying the setting process of each unit when the central processing unit is inserted or removed or replaced.

[Means for solving problems]

The present invention relates to a unit setting management device comprising a central processing unit and a plurality of units which constitute the apparatus and whose operation setting or operation control is performed by the central processing unit, wherein each unit has its own unit. First storage means for storing whether or not operation has been set, second storage means for storing setting contents set from the central processing unit, and storage contents of the first and second storage means And an interface section for transmitting to the central processing unit,
The central processing unit stores the storage content of the first and second storage means transmitted from each unit, and the storage of the first storage unit when resetting each unit. Refer to the contents, if the stored content is a unit that has already been set, reset using the stored content of the second storage means, and if the unit has no setting, the second storage means of the settable unit And a means for resetting based on the stored contents.

[Action]

Each of the units constituting the device stores the operation setting contents and the operation control setting contents of the unit in its internal memory, and also stores whether or not the setting has been completed.

When the central processing unit is inserted or removed or replaced, the above-mentioned stored contents are transmitted to the non-volatile memory provided in the central processing unit via the interface section for copying, and the central processing unit is configured to copy each unit according to the copied stored contents. Reset.

〔Example〕

 Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is a block diagram showing an embodiment of the present invention.

This embodiment, unit 2 ₁ constituting the electronic device is connected to the central processing unit 1 to the central processing unit 1,
It has 2 ₂ ... 2 _n .

The central processing unit 1 has a unit 2 inside it.
A nonvolatile memory 11 for storing the memory contents read from ₁ , 2 ₂ , ..., 2 _n is provided. The units 2 ₁ , 2 ₂ , ... 2 _n connected to the central processing unit 1 respectively store setting content storage memories 22 ₁ , 22 for storing the setting contents such as operation settings and operation control set by the central processing unit 1. ₂ , …… 2
1-bit memory that stores 2 _n and the setting status of its own unit
21 ₁ , 21 ₂ , ... 21 _n, and interface sections 23 ₁ , 23 for transmitting the contents of these two memories to the central processing unit 1
₂ , ... 23 _n .

Next, the operation of the apparatus of this embodiment will be described.

The apparatus of this embodiment is, for example, a subscriber line carrier, and the subscriber line carrier has channel device units corresponding to several tens of lines inserted therein, and the central processing unit 1 includes each channel device unit. The setting of each unit 2 is performed. The central processing unit 1 sets, for example, a signaling type of the channel device unit, a protocol, or a value of an equalizer or an attenuator of the channel device unit as setting contents.

The setting memory 22 ₁ through 22 _n of the units 2 ₁ to 2 _n, and stores the set operating settings or operation control content when the central processing unit 1 has set the unit 2 ₁ to 2 _n There is. The 1-bit memories 21 _{1 to} 21 _n store whether or not the own unit has been set by the central processing unit 1.

Therefore, when replacing the central processing unit 1 for such upgrading or maintenance, newly exchanged central processing unit 1 resetting the resetting or control of the operation units 2 ₁ to 2 _n, respectively Need to do. Thus, the central processing unit 1, the unit 2 ₁ to 2 _n of the 1-bit memory 21 ₁ through 21 _n and purpose storage memory 22 ₁ through 22 _n interface portion 23 ₁ a stored content of ~ 23 _n
Read out via and to copy to the non-volatile memory 11. Then, the newly exchanged central processing unit 1 refers to the copied information of the 1-bit memories 21 _{1 to} 21 _n , and each unit 2
_For the unit 2 in which _{1 to} 2 _n 1-bit memories 21 _{1 to} 21 _n have been set, the same information is reset. When the central processing unit 1 is replaced, the peripheral units may be replaced at the same time. In this case, the unit 2 replaced at the same time.
The contents of the 1-bit memories 21 _{1 to} 21 _n are not set. For the unit 2 in which the contents of the 1-bit memories 21 _{1 to} 21 _n have not been set, the central processing unit 1 recognizes whether or not there is a unit of the same type, and if there is a unit 2 of the same type, it is set. Therefore, the setting is performed with the setting contents copied from the unit 2 of the same type to the nonvolatile memory 11. Since it is not possible to make settings for different types of units, make external settings as usual.

The operation flowchart of this embodiment is shown in FIG.

This embodiment, as is necessary not to give artificially newly set contents units 2 ₁ to 2 _n against external to the central processing unit 1 when replacing the central processing unit 1.

〔The invention's effect〕

As described above, according to the present invention, since the setting contents set in the units forming the apparatus can be read out and reset by the central processing unit, when the central processing unit is replaced or inserted / removed or replaced for maintenance of the apparatus. For example, when the version of the central processing unit is upgraded, it is no longer necessary to externally provide the central processing unit with the operation settings and operation control settings of each unit, which has the effect of simplifying the setting management.
