2. Description of the Related Art A conventional breaker for an electronic computer has a function of tripping when an overcurrent is detected and also a function of tripping by a signal from the outside. The temperature detector has the function of outputting a signal when the temperature exceeds a certain set temperature, and when the temperature exceeds a certain set temperature during operation, in order to prevent equipment failure, an abnormal temperature is sent to the outside. Notify me. Also, as a two-stage operation temperature detector, it has the function of outputting a signal when the temperature exceeds a certain specified temperature, and trips BK when the temperature exceeds a certain set temperature to prevent equipment failure. Or prevent fire of equipment. Then, in order to guarantee the operation of the device, the detected temperature is adjusted in advance to the product specification.

Therefore, when TRIP outputs a signal, C
Since BK is tripped regardless of the operation of PU, there is a possibility of data destruction of CPU. Figure 3 shows the operation timing
Show to. That is, in FIG. 1, the temperature increases and the ALM set value 3
The ALM notification 33 is output at the point 37 intersecting with 2,
Notify outside. If the temperature rises further, trip signal 36 is output at point 30 and the circuit breaker is tripped. However, the computer is in the process of blackout countermeasures due to point 34, and the computer cannot be guaranteed in some fields like the frame 35.

In the computer apparatus with the temperature abnormality processing function of the present invention, it is detected that the temperature of the equipment is higher than or equal to the preset low temperature, and a low temperature alarm is output, and the temperature of the equipment is low. A high temperature alarm is output by detecting that the temperature is higher than a preset high temperature at a temperature higher than the temperature, and the low temperature alarm performs the power failure countermeasure processing of the computer, and the power failure countermeasure processing by the shutdown function is completed. It is detected that the high temperature alarm is activated, the preset time is measured, the timer is activated, and the timer function is activated or the shutdown process completion detection function is activated, whichever is earlier. ..

EXAMPLE An example of the present invention will be described below. FIG. 2 shows a low temperature detector 3 that detects when the temperature of the device has risen above a preset low temperature and outputs a low temperature alarm, and a high temperature that is preset when the temperature of the device is higher than the low temperature. The high temperature detector 4 that detects when the temperature is higher than or equal to the temperature and outputs a high temperature alarm, the shutdown processing function 2b that executes the power failure countermeasure processing of the computer 2 by the low temperature alarm, and the power failure countermeasure processing by the shutdown function 2b Of the shutdown processing completion detection function 2a that detects completion, the timer function 5 that measures a predetermined time by the high temperature alarm and operates in a timed manner, and the operation of the timer function 5 or the shutdown processing completion detection function 2a Whichever comes first, computer 2
2 shows a computer device with a temperature abnormality processing function, which is provided with a circuit breaker 1 for cutting off the power supply of FIG.

That is, the circuit breaker 1 has a function of tripping when an overcurrent is detected, and a function of tripping with an external signal. The timer function 5 is a circuit for delaying a signal in which TRIP outputs an abnormality for a certain period of time and then outputting the signal to the OR circuit. The OR circuit 6 delays the signal input by the timer circuit and the CPU. It is a circuit for tripping BK by either of the signals that have completed the shutdown processing. Then, 7 is a signal notifying that the operation of the CPU has ended.

The timer setting time is set to a time longer than the shutdown time of the computer system (time can be estimated approximately by the capacity of the main storage capacity and auxiliary storage of the system (DISK device etc.)). To do.

In a temperature environment where the operation of the product cannot be guaranteed due to the temperature rise during computer operation, when the temperature exceeds the preset temperature A of the product, the low temperature detector 3 detects the temperature and the electronic computer 2 is detected. Outputs a temperature abnormality signal. The signal causes the electronic computer 2 to terminate the processing currently in operation and shut down, and then notifies the OR circuit 6 of the termination of the operation by a signal 7. Also, timer function 5
Is a high temperature detector 4 that detects the temperature due to a rapid temperature rise.
The signal from is delayed by B for a predetermined time and output to the OR circuit 6. The OR circuit 6 trips the circuit breaker 1 when a signal from either the electronic computer 2 or the timer function 5 is input. The operation timing is shown in FIG. In FIG. 2, 21 is the start of the timer circuit, 22 is the end of the timer circuit, 23 is the start of the shutdown process, 2
Reference numeral 4 indicates the end of the shutdown processing.

It should be noted that the temperature A is a temperature at which the operation cannot be guaranteed by the product specifications of the equipment, and the constant time B is taken into consideration when the shutdown completion signal of the computer 2 cannot be notified to the OR circuit 6 due to some trouble. This is the time for tripping the circuit breaker in consideration of the estimated shutdown time.

In the apparatus of this embodiment, the computer itself can turn off the power after knowing the temperature rise and completing the shutdown process. Therefore, compared to the method of forcibly shutting off the power, it is possible to prevent equipment failure and fire prevention, including protection of data, etc. Also, due to the provision of a timer, a shutdown processing end signal is output from the CPU. Even if it does not exist, it can be automatically shut off, further improving safety. Note that the same function can be realized with a timer alone without providing an operation end signal, but the shutdown processing time differs for each system, so a longer time must be set and the shutdown can be performed promptly after the processing ends. Absent. That is, according to the present invention, a temperature detector (ALM and TRIP) which outputs a signal when the ambient temperature exceeds a preset temperature.
After receiving the ALM signal and performing the shutdown process,
It is possible to provide a computer device with a temperature abnormality processing function, which is provided with a breaker that receives a signal from the CPUTRIP that outputs an end signal and, after a predetermined time, shuts off by a signal from a timer that outputs a breaker shutoff signal.

[0013]

EFFECTS OF THE INVENTION Even when the circuit is cut off due to the temperature rise of the equipment, the computer data can be saved and the shutdown processing can be performed completely.
