Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a plurality of peripheral units which can be inserted and removed, and a CP which performs operation setting, operation control, and the like for the plurality of peripheral units.
The present invention relates to an apparatus including a U unit, and particularly to an operation setting method for a peripheral unit.

[Conventional technology]

In a device such as a subscriber transmission device or the like in which a peripheral unit such as a printed board unit performs part of the functions performed by the device and one or more CPU units perform other functions such as control and management of the entire device, In some cases, an operation setting of setting the internal state to a desired state is required in order for each peripheral unit to start operation from a desired state. Such an operation setting becomes complicated by manual operation when the number of peripheral units increases, and it becomes difficult to perform operation setting correctly and quickly. Therefore, there is no proposal for a device in which the operation setting of the peripheral unit is performed by the CPU unit. Has been put to practical use. This means that when the CPU unit is reset, the CPU unit accesses each peripheral unit and sets the operation thereof. Each unit is configured to be freely inserted into and removed from the apparatus, and can be removed or mounted during operation of the apparatus for inspection, replacement, and the like. When removing or installing a peripheral unit to remove and inspect a certain peripheral unit during operation of the device, or to replace it with another peripheral unit, it is necessary to set operation again for the peripheral unit after installation Become. For this reason, a function to set the operation of the peripheral unit in response to an artificial operation setting instruction from outside the device other than at the time of reset is provided.
It is usually added to the CPU unit.

[Problems to be solved by the invention]

However, re-netting the CPU unit every time the operation setting of the peripheral unit is required is a problem because the function of the device is temporarily stopped. In addition, in a method in which an artificial operation setting instruction is externally provided in order to perform an operation setting of the peripheral unit without stopping the function of the apparatus, the maintenance of the apparatus becomes complicated accordingly, and the apparatus may malfunction due to a human error. The nature is also large.

Therefore, an object of the present invention is to provide an operation setting method of a unit which can automatically set an operation for the peripheral unit simply by attaching the peripheral unit to the device.

[Means for solving the problem]

In order to achieve the above object, the operation setting method of the unit according to the present invention includes a complex peripheral unit which can be inserted and removed and a CP which performs operation setting, operation control, etc. for the plurality of peripheral units.
In an apparatus including a U unit, in each of the peripheral units, storage means for storing data indicating whether or not operation setting from the CPU unit has been completed, and reading and reading of data from the CPU unit to the storage means. An interface that enables writing, the CPU
The unit periodically reads out the data stored in the storage means of each of the peripheral units via the interface, and when the data indicates that the operation setting has not been completed, a predetermined operation setting for the peripheral unit is performed. After that, data indicating that the operation setting has been completed is written into the storage means via the interface.

[Action]

In the operation setting method of the unit of the present invention, the storage means of each peripheral unit holds data indicating whether or not the operation setting of the own peripheral unit has been completed, and the interface is provided when the own peripheral unit is mounted on the device. In this state, it is possible to read and write data from the CPU unit to the storage means in its own peripheral unit, and the CPU unit periodically reads the data stored in the storage means of each peripheral unit mounted on the device into each interface. When the data is read through the face and indicates that the operation setting has not been completed, the predetermined operation setting is performed for the peripheral unit, and then the data indicating that the operation setting has been completed is stored in the storage unit. Write via interface.

〔Example〕

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

FIG. 1 is a block diagram showing an example of an apparatus to which the operation setting method of a unit according to the present invention is applied. The apparatus of this embodiment includes a CPU unit 1 and a plurality of peripheral units 2 to 6. The peripheral units 2 to 6 are units that perform a part of the functions of the present apparatus, and can be inserted into and removed from the present apparatus by connectors CN1 to CN5. CPU unit 1
Is capable of transmitting information to and from each of the peripheral units 2 to 6 via an information transmitting means such as a bus BUS and each of the connectors CN1 to CN5 in the present embodiment. It is responsible for overall control and management of the device.

Peripheral unit 2 has 1 bit memory 21 and interface
22 is added. The 1-bit memory 21 is a memory that holds 1-bit data indicating whether the operation of the own peripheral unit 2 has been set. For example, when the operation has been set, the logical value “1” is set. Holds 0 ". The 1-bit memory 21 can use an area such as a RAM that the peripheral unit 2 originally has, or can be configured by a flip-flop. The 1-bit memory 21 is reset to "0" when the peripheral unit 2 is mounted on the apparatus and power is supplied. The interface 22 is an interface for enabling reading and writing of data from the CPU unit 1 to the 1-bit memory 21. Other peripheral units 3, 4, 5,
6 also has 1-bit memory 31, 41, 51, 61
And interfaces 32, 42, 52, and 62.

FIG. 2 shows an example of an operation setting process periodically executed by the CPU unit 1 during its operation. Hereinafter, the operation of this embodiment will be described with reference to FIG. 1 and FIG.

When the confirmation time of the operation setting state of the peripheral unit comes, as shown in FIG. 2, the CPU unit 1 transmits 1 bit of one of the plurality of peripheral units 2-6, which have not been confirmed this time, to the peripheral unit. The data stored in the memory is read through the interface (step S1),
It is determined whether the data is "1" (operation set) (step S2). Then, if the data is “1”, it is determined whether or not an unconfirmed peripheral unit remains (step
S3) If it remains, return to step S1 and perform the same operation as described above for the unconfirmed peripheral units, and when the operation setting state confirmation for all peripheral units is completed,
This processing ends. When it is determined in step S2 that the data is "0" (operation not set), the peripheral unit is accessed, and the predetermined operation setting is performed in accordance with the operation setting stored in the memory in the CPU unit 1 in advance. Is performed (step S4). Then, "1" is written to the 1-bit memory via the interface (step S5), and the process proceeds to step S3. In this way, the CPU unit 1 periodically checks the data in the 1-bit memories 21 to 61 of the peripheral units 2 to 6 and, if there is a peripheral unit whose operation is not set, sets the operation for it. I have.

In this embodiment, since the above-described configuration and operation are performed, for example, when the peripheral unit 2 is replaced with another peripheral unit 2 'during the operation of the apparatus, if the peripheral unit 2' is mounted on the apparatus, "0" is stored in its 1-bit memory. Is initially set, and in the operation setting confirmation processing of the next cycle of the CPU unit 1, it is detected that the peripheral unit 2 'is not set to operate, and the operation setting is automatically performed.

〔The invention's effect〕

As described above, in the operation setting method of the unit of the present invention, the data stored in the storage unit of the peripheral unit mounted on the device is periodically read by the CPU unit, and the operation setting is not completed. In the case of, the operation setting is performed for that peripheral unit, so if a certain peripheral unit is replaced with another peripheral unit, or if it is removed once for inspection etc. Operation setting is performed for the peripheral unit. Therefore, the operation can be automatically set without stopping the operation of the apparatus and without manually inputting a command from outside.
