Abstract

PURPOSE:To decrease the power consumption and to prolong the lifetime of each of distribution processing units by providing a loop control power supply part and a unit process power supply part on each title processing unit and adding a power supply control state in order to obtain a unit constitution accordant with the operating state and therefore driving/interrupting the unit process power supply part. CONSTITUTION:A loop control part 1 of a distribution processing unit receives a command addressed to its own from a loop circuit 5, and a sequence control circuit 6 is operated to fetch a command to a command register 7. The contents of the register 7 are interpreted by a command detector 8. In the case of a unit inherent action, the output of the decoder 8 which instructs the working of a unit process part 4 with a control signal instructs the supply of power and the interruption of power to a unit process power supply part 3 with the power supply ON and OFF signals respectively.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a distributed processing unit connected to a loop-shaped line.

[Conventional technology]

Conventional distributed processing units have one internal power supply system, and when connected to a loop circuit, the power supply section is always in operation and power is supplied.

In addition, the distributed processing units connect only the necessary number with the same function and the necessary number with different functions to the loop line, forming functional unit groups, respectively.
It constituted one distributed processing device.

[Problem to be solved by the invention]

The conventional distributed processing unit described above has a single internal power supply unit, so even if the operating status of the distributed processing device changes and you want to operate it with the optimal number of units within the same functional group, it is unnecessary. There was a problem in that it was not possible to turn off the power to the unit, which was extremely wasteful in terms of power consumption and lifespan.

An object of the present invention is to provide a distributed processing unit that solves the above problems by dividing the power supply section into a loop control section and a unit processing section.

[Means to solve the problem]

The distributed processing unit of the present invention includes a loop control section that generates various control signals based on data received from the loop line and sends out transmission data to the loop line, a loop control power supply section that supplies power to the loop control section, and a loop control power supply section that supplies power to the loop control section. It has a unit processing section that performs specific processing operations in response to control signals, and a unit processing power supply section that supplies power to the unit processing section and turns on and off the power supply according to a power control signal from the loop control section.

〔Example〕

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

FIG. 1 is a block diagram showing an embodiment of a distributed processing unit of the present invention. The loop control unit 1 includes a sequence control circuit 6 that generates various timing signals. It consists of a command register 7 that takes in command data from a loop line, and a command decoder circuit 8 that interprets command codes and sends out control signals. The loop control power supply unit 2 constantly supplies power to the loop control unit 1. The unit processing power supply section 3 is controlled by a power-on signal and a power-off signal from the loop control section 1, and supplies power to the unit processing section 4. The unit processing section 4 executes unit-specific operations based on control signals from the loop control section 1.

Next, we will discuss specific operations. When the loop control section 1 of the distributed processing unit receives command data addressed to itself from the loop line 5, the sequence control circuit 6 operates and takes in the command into the command register 7. The contents of the command register 7 are interpreted by a command decoder 8, and in the case of a unit-specific operation, a control signal is used to instruct the unit processing section 4 to perform the operation.If the output of the command decoder 8 is a power-on signal, it is sent to the unit processing power supply section 3. If the signal is a power-off signal, the power is turned off.

FIG. 2 shows an example of a distributed processing device including several distributed processing units. Distributed processing unit 21-1.21-2 with the same function. ... Distributed processing unit group A where 21M are assembled, other distributed processing units 22-1, 22-2, ..., 22-N with the same function
Distributed processing unit group B and unit group A
and a system management unit 10 that monitors and controls the quantity of each unit in unit group B.

In unit group A and unit group B in Figure 2, when the unit group A and unit group B are in the maximum scale operation state, a power-on command is sent to all distributed processing units via the loop line, but when the unit group A and unit group B are in the reduced operation state, unnecessary distributed processing units are sent. Sends a power-off command to

〔Effect of the invention〕

As explained above, the present invention provides each distributed processing unit with a loop control power supply section and a unit processing power supply section, adds a power control state, and drives and disconnects the unit processing power supply section according to the unit configuration suitable for the operating state. This has the effect of reducing power consumption and extending life.
