Abstract

PURPOSE:To control gathering of trouble data by sending a trouble data gathering control signal from a trouble data gathering controller to a distribution board and using a specific frequency band to transmit this signal from the distribution board to each device, where gathering of trouble data should be controlled, through a power cable. CONSTITUTION:The trouble data gathering control signal outputted from a trouble data gathering controller 1 is sent to a distribution board 2, and the trouble data gathering control signal modulated with a specific frequency band by a modulating/demodulating part 22 is superposed on the power frequency and is connected to a device 3, where gathering of trouble data should be controlled, through a power supply cable 201. A modulating/demodulating part 32 in this device 3 extracts only the signal of the specific frequency band and sends it to a unit 33, where gathering of trouble data should be controlled, to control gathering of trouble data. A signal of control results is sent to the trouble data gathering controller 1 through a power supply line 102 in the same manner. Thus, gathering of trouble data in each trouble data gathering controller is controlled.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a fault data collection control method for a computer system.

[Conventional technology]

Conventionally, this type of fault data collection control method collects fault data for each faulty data collection control device by sending a fault data collection control signal to each faulty data collection control device based on an instruction from the central processing unit of the computer system. was in control.

[Problem to be solved by the invention]

In the conventional fault data collection control method described above, fault data collection is controlled for each fault data collection control device by instructions from the central processing unit of the computer system. There are problems in that an error in the command for implementing fault data collection control causes a fault in the system, and there is a drawback that a cable for fault data collection control must be added.

[Means to solve the problem]

The fault data collection control method of the present invention sends a fault data collection control signal from the fault data collection control device to the distribution board, and the distribution board that receives the signal sends the fault data collection control signal to each faulty data collection control device. It has the feature that it is possible to perform fault data collection control for each faulty data collection control device by transmitting and receiving fault data collection control signals using a specific frequency band while supplying power via the power cable. .

〔Example〕

Next, the present invention will be explained with reference to the drawings.

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

A power source is connected to the input side of an isolation transformer 21 in the distribution board 2 via an input line 101. The output (secondary) side of the isolation transformer 21 is insulated from the input side for high frequencies, and is connected to the power supply line 102 to the faulty data collection control device 3 and each component device that make up the computer system. Connected.

A fault data collection control signal output from the fault data collection control device 1 is connected to a modulation/demodulation section 22 in the distribution board 2 via a fault data collection control cable 11. By connecting the modulation/demodulation unit 22 to the power supply line 102 inside the distribution board 2, a fault data collection control signal modulated using a specific frequency band is superimposed on the power frequency, and the data collection control device is 3 via a power supply cable 201.

In the faulty data collection control device 3, the power supply cable 2
Of the power and failure data collection control signals from 01, the power is effectively supplied to the power supply unit 31, and the demodulation unit 32 extracts only signals in a specific frequency band and sends them to the failure data collection control unit 33. , failure data collection control is performed.

The data signal resulting from the fault data collection control is modulated to a specific frequency by the demodulation section 32 from the faulty data collection control unit 33, transmitted from the power supply cable 201 via the power supply line 102, and then sent to the modulation/demodulation section 22. The signal is demodulated and sent to the fault data collection control device 1.

〔Effect of the invention〕

As explained above, the present invention sends a fault data collection control signal from a fault data collection control device to a distribution board, and upon receiving the signal, the distribution board sends a fault data collection control signal to each faulty data collection control device. Conventionally, by using a configuration in which fault data collection control is performed for each faulty data collection control device by sending a fault data collection control signal via the power cable of the data collection control device, each computer system This eliminates the disadvantage that errors in commands for performing faulty data collection control cause system failures, and has the advantage that cables for faulty data collection control can be eliminated.
