DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement in a system for automatically starting (starting) a package used in a transmission device or the like.

[0002] In recent years, with the increase in the functions of the transmission device and the like, the contents of various states set in a single package have increased, and so the so-called soft strap system in which the settings are made by software has become mainstream. For this reason, if the package is replaced when the package is added or when the package breaks down, the setting with the soft strap is required again. However, automatic startup (startup) is required to facilitate maintenance and prevent human error. It has become common to do.

[0003] In this case, there is a demand for an automatic start-up processing system which can prevent the setting contents of various states from being lost even if a package is inserted or removed during the start-up processing.

[0004]

2. Description of the Related Art FIG. 3 is a block diagram showing a configuration of a conventional controlled package. In the case where the transmission device is composed of a plurality of controlled packages and a control package that performs a process of starting up the circuits of the controlled packages, an operation of a process of starting (starting) the circuits of the controlled packages will be described. .

First, when power is turned on, the voltage monitoring circuit 1 of the controlled package shown in FIG. 3 recognizes this and outputs, for example, a signal of "1" indicating a start-up request, and outputs a set / reset flip-flop (hereinafter referred to as "set / reset flip-flop"). FF2), and temporarily stored at FF2. Then, the FF 2 outputs “1” from the Q terminal at the timing of a clock (not shown) and transfers it to a control package (not shown) installed in the same transmission device via the transmission circuit 3.

On the other hand, the control package (not shown) receives a signal of "1" indicating a start-up request from the controlled package and sends the signal to the soft strap section 5 of the controlled package shown in FIG. Perform soft strap (start-up process). When the processing of the soft strap is completed, a signal "0" indicating cancellation of the start-up request is transferred from the control package (not shown) to the controlled package shown in FIG. In the controlled package, the signal of "0" is received by the receiving circuit 4 and added to the clear (CLR) terminal of the FF2, and the output of the Q terminal of the FF2 is set to "0" to cancel the start-up request.

In this manner, the startup (startup) processing of the circuit of the controlled package has been performed.

[0008]

However, in the above-described automatic start-up processing method, the control package recognizes a start-up request ("1") from the controlled package and restarts the power supply during the start-up processing. Even if it goes from off to on,
Since the state of the controlled package remains "1", the destruction of the set contents cannot be recognized.

That is, there is a problem in that the setting contents are lost due to poor fitting when the controlled package is inserted into the connector of the device and re-insertion / removal of the controlled package during the start-up process.

Accordingly, an object of the present invention is to provide an automatic start-up processing system which can prevent the setting contents of various states from being lost even if a package is inserted or removed during the start-up processing.

[0011]

The above problem is solved by the structure of the package shown in FIG. That is, in FIG. 1, a first package mounted with a first set / reset unit 200 that outputs a start-up request signal when power is turned on and stops outputting the start-up request signal by a control signal from the second package. Receiving an activation request signal of the output of the first set / reset unit 200 of the first package, and performing an activation process of a circuit mounted on the first package. In the start-up processing method, the second set / controller 600 is provided in a first package, outputs a start-up request signal when the power is turned on, and stops outputting the start-up request signal by a control signal from the second package. This is a reset unit.

When the second package receives a start-up request signal for the output of the first and second set / reset units 200 and 600, it outputs a control signal from the second package and outputs the first or second control signal. The output of the start-up request signal of the second set / reset units 200 and 600 is stopped.

When the start-up processing of the circuit mounted on the first package in the second package is completed, a control signal is output from the second package and the first package of the first package is output.
The second set / reset units 200 and 600 are configured to stop the output of the start request signal.

[0014]

In FIG. 1, when the power is turned on, a start-up request signal (for example, "1", respectively) is output from the first and second set / reset units 200, 600 of the first package to the second package. I do. On the other hand, when the second package receives a start-up request signal (for example, "11") of the output of the first and second set / reset units 200, 600, the first or second set / reset unit 200, 600 Control signal for stopping the output of one of the start-up request signals. Then, the output of one of the first and second set / reset units 200 and 600 of the first package is stopped.

As a result, on the second package side, the reception state is "10" or "01". Next, the second
When the start-up processing of the circuit mounted on the first package is completed in the first package, the first and second set / reset units 200 and 600 of the first package are changed from the second package.
A control signal for stopping the output of the start-up request signal is output. Then, the output of the start request signal of the first and second set / reset units 200 and 600 of the first package is stopped. At this time, the receiving state is “00” on the second package side.

As a result, during the start-up processing in the second package (at this time, it is "10" or "01")
When the power is turned on again after inserting and removing the package of
Since the value is "11" on the second package side, the insertion / removal state can be recognized on the second package side, and by performing the start-up process again, the loss of the setting contents can be prevented.

[0017]

FIG. 2 is a block diagram showing the configuration of a controlled package according to an embodiment of the present invention. The same reference numerals indicate the same objects throughout the drawings.

The present invention is different from the conventional example in that the signal for the start-up request output from the controlled package is 1 bit ("1" or "0"). The point is that the package side performs the sequence management of the start-up processing by judging the 2-bit signal. This will be described in detail below.

In FIG. 2, when a power supply of a device provided with a controlled package and a control package (not shown) is turned on, a voltage monitoring circuit 1 of the controlled package shown in FIG.
Recognizing this, for example, outputs a signal of "1" indicating a start-up request, and in addition to the preset (PR) terminal of the FF2 and the newly provided FF6, the FF2 and 6 temporarily hold the signal.
The FFs 2 and 6 output “1” from the Q terminal at the timing of a clock (not shown), respectively, and transmit a 2-bit serial or parallel signal “11” to a control package (not shown) via the transmission circuit 3. Forward.

On the other hand, the control package (not shown) receives the 2-bit signal "11" indicating the start-up request from the controlled package and recognizes this state. A signal ("0") for clearing is sent to the controlled package, added to the clear terminal (CLR) of FF2 of the controlled package, and the Q terminal output of FF2 of the controlled package is cleared to "0". At this point, the output of the transmission circuit 3 of the controlled package is "01".

Thereafter, in a control package (not shown), a signal for clearing the FF 6 of the controlled package is executed at the end of the processing by executing a process for starting up (starting) the circuit of the soft strap unit 5 of the controlled package. ("0")
To the controlled package to send the clear terminal (CL
In addition to R), the output of the Q terminal of FF6 is cleared to "0". At this time, the output of the transmission circuit 3 of the controlled package is "00".

During the start-up processing of the control package (not shown) (the output of the transmission circuit 3 is "01" at this time), the controlled package is replaced with a new controlled package. It is assumed that the power is turned on from off. Then, the voltage monitoring circuit 1 of the controlled package shown in FIG. 2 recognizes this, outputs a signal “1” indicating a start-up request, and applies it to the preset terminals (PR) of FF2 and FF6. In both cases, "1" is temporarily held. Then, “1” is output from the Q terminals of the FFs 2 and 6 at the timing of a clock (not shown), and transferred to a control package (not shown) as a signal of “11” via the transmission circuit 3.

The control package (not shown) receives the above "11" during the start-up process (at this time, the output of the transmission circuit 3 is "01") and recognizes that the controlled package has been inserted or removed. Then, the ongoing start-up process is stopped, and the start-up process for the controlled package is started again from the beginning.

As a result, even if the controlled package is inserted / extracted during the start-up processing of the control package, the state of the insertion / extraction can be recognized on the control package side, so that the setting contents can be prevented from being lost.

[0025]

As described above, according to the present invention, even if the controlled package is inserted / extracted during the start-up processing of the control package, the insertion / extraction state can be recognized on the control package side. Content can be prevented from being lost.
