Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an information processing device having a remote power-on function, and more particularly to a remote power-on processing method that can prevent malfunctions even at low temperatures.

[Conventional technology]

As described in Japanese Patent Application Laid-Open No. 58-134.321, conventional devices detect when the room temperature of a computer system falls below a predetermined value, issue an alarm, and cut off the power supply to the computer. The device was protected by However, air conditioning equipment was required to keep the room temperature at a predetermined value.

[Problem that the invention seeks to solve]

In an information processing device, when the power is turned on at a low temperature (for example, 5° C. or lower), circuit malfunctions occur due to the temperature characteristic conditions of the components, and failures such as failure to properly load an initial program often occur.

In the past, the power was turned on only after the environmental conditions were satisfied with the air conditioning equipment, etc. However, with the introduction of a remote power-on function and the power-on process, it became possible to control the environment at the location where the equipment was installed. It has become difficult to control from a remote location.

In particular, in environments where distributed information processing equipment is installed in large-scale online systems (e.g. branches of banks, securities companies, etc.), there are many cases where air conditioning equipment etc. are not provided for the information processing equipment, and remote power-on mechanisms are used early in the morning. Even when the power is turned on, the circuits do not operate properly due to the low temperature, resulting in many failures that prevent the equipment from starting up properly.

An object of the present invention is to realize remote power-on processing that can prevent malfunctions even at low temperatures that do not satisfy environmental conditions.

[Means for solving problems]

The above purpose is to use a temperature detection sensor to continue the system reset state for the control unit after the power is turned on by a remote power-on command until the temperature reaches a point where the device can operate normally. This is achieved by starting the initial program load only when the conditions are satisfied.

[For production]

When the temperature detection sensor no longer satisfies a temperature condition set according to the temperature characteristics of the components of the information processing device, the temperature detection sensor transmits the information to the reset circuit to perform a system reset. This makes it possible to control the power-on process of the information processing device in an environment where the temperature conditions are not satisfied, thereby preventing malfunction of the device.

〔Example〕

Hereinafter, one embodiment of the present invention will be described with reference to the drawings.

FIG. 1 is a schematic block diagram of an information processing system equipped with a remote power-on function.

The information processing device 2 is connected to the information processing device 1, which is a host device, through an information transmission line 8, and both devices transmit data through the information transmission line 8.

In the system shown in FIG. 1, the information processing device 2 automatically operates in response to a power-on command sent from the information processing device 1 through the information transmission line 8 for unmanned operation or to save the operator's time. The system allows remote power control to turn on the power.

The auxiliary power supply 4 is a power supply that supplies power to the power supply control section 3, and the main power supply 6 is a power supply that supplies power to the information processing section 5, respectively, and supplies necessary DC output or AC output to each from an AC input.

3.

When the power supply control unit 3 detects a power supply command sent through the information transmission line 8, it controls the main power supply.

The information processing unit 5 is a part of the information processing device 2 that performs information processing. The auxiliary power source 4 and the main power source 6 have separate power switches, so that when the auxiliary power source 4 is turned on, the main power source 6 can be turned on manually by the operator or by a command from the information processing device 1. It has become. In addition,
These power switches are omitted here because they have no relation to the present invention.

The temperature monitoring sensor unit 7 is a part that detects temperature abnormality inside the casing of the information processing device 2, and when a temperature abnormality is detected,
The information processing unit has been reset and continues to be reset until the temperature conditions are satisfied.

FIG. 2 is a schematic block diagram of the information processing device 2. As shown in FIG.

The information transmission line 8 is received by a receiver circuit 9, and the signal level is exchanged to become transmission data 14.

Transmission data 14 is input to the power-on command detection circuit 10 . The power-on command detection circuit 10 remembers a predetermined bit pattern of the power-on command (temporarily referred to as pattern A), and determines whether the pattern of the input transmission data 14 matches this pattern or not. We are checking sequentially. When the same bit pattern as pattern A is detected, the power-on command detection circuit outputs a pulse signal to the power supply control circuit 11. Power supply control circuit 11
When receiving the pulse signal, it outputs a power-on signal 15.

The power-on signal 15 is input to the main power supply 6, and the main power supply 6 turns on the power at the rising edge of the power-on signal.

When the main power supply 6 is turned on, the ambient temperature is abnormally low (temporarily below 5℃)
In this case, the temperature detection sensor 13 detects a low temperature abnormality and notifies the system reset circuit 12. The system reset circuit 12 outputs a system reset signal 16 to the information processing section. While inputting the system reset signal 16,
The information processing unit 5 does not operate.

During this period, the temperature detection sensor 13 releases the low temperature abnormality when the temperature condition is satisfied due to the temperature increase inside the housing due to the energization. As the low temperature abnormality is removed, the system reset signal 16 is turned off and the information processing section 5 starts operating.

The above time chart is shown in FIG.

According to this embodiment, there is an effect that remote power-on processing of an information processing device in an environment where temperature conditions are not satisfied can be controlled without malfunction.

〔Effect of the invention〕

According to the present invention, circuit malfunction can be prevented even if the power is turned on to an information processing device at a low temperature, and even if the room temperature around the device is not adjusted, the power can be turned on from a remote location and four people can operate the device. .
