Specific embodiment
To make the object, technical solutions and advantages of the present invention clearer, below in conjunction with accompanying drawing to each reality of the invention
Example is applied to be explained in detail.However, it will be understood by those skilled in the art that in various embodiments of the present invention, in order to
Reader is set to more fully understand the application and propose many ins and outs.But, even if without these ins and outs and based on
Under each embodiment many variations and modification, it is also possible to realize the application technical scheme required for protection.
The first embodiment of the present invention is related to a kind of fault detection method.It is applied to the electricity comprising input unit and processor
Sub- equipment, when the output function of input unit breaks down, exports the trigger signal of the first level to processor, works as processor
Response function break down or when the output function of input unit breaks down, the electricity of response pin output first of processor
Flat response signal.The flow of the fault detection method of the present embodiment is as shown in figure 1, specific as follows：
In a step 101, when the response pin of processor exports the response signal of the first level, by trigger signal and the
The response signal of one level carries out same or logical operation, and generates operation result.Specifically, the first level in the present embodiment
Can also be able to be low level for high level.When trigger signal is identical with the level of response signal, transported through same or logical operation
Operation result after calculation is high level signal, when the level of trigger signal and response signal is differed, through same or logical operation
Operation result after computing is low level signal.In the present embodiment, it can be assumed that the first level is low level, i.e., in processor
When response pin exports low level response signal, trigger signal and low level response signal are carried out into same or logical operation,
And operation result is generated, and when operation result is low level, illustrate that trigger signal is differed with the level of response signal, that is, trigger
Signal is high level signal, when operation result is high level, illustrates that trigger signal is identical with the level of response signal, that is, trigger
Signal is also low level signal.
In a step 102, judge the operation result whether be second electrical level signal.Specifically, in the present embodiment
One of first level and second electrical level are high level, and another is low level.That is, when the first level is electricity high
Usually, second electrical level is low level；When the first level is low level, second electrical level is high level.Is assumed in the present embodiment
One level is low level, and second electrical level is high level, then when signal of the operation result for second electrical level (high level), illustrate to touch
Signal identical with the level of response signal, i.e., trigger signal is also low level signal, when operation result is not second electrical level (high
Level) signal when (operation result be low level signal), illustrate that trigger signal is differed with the level of response signal, i.e.,
Trigger signal is high level signal.In this step if the determination result is YES, illustrate that operation result is second electrical level (high level)
Signal, then into step 103, otherwise illustrate that operation result is the signal of the first level (low level), then into step 104.
In step 103, output characterizes the configured information that the output function of input unit breaks down.Specifically, originally
In embodiment, when signal of the operation result for second electrical level (high level), illustrate that trigger signal is low level (the first level)
Signal, illustrates that the output function of input unit breaks down, then output characterizes the finger that the output function of input unit breaks down
Show information.Configured information in the present embodiment can be indicator lamp information or text information.Such as, when operation result is the
During two level (high level), indicator lamp is bright, represents that the output function of input unit breaks down, or directly with word output
The information of " output function of input unit breaks down ".
At step 104, output characterizes the configured information that the response function of processor breaks down.Specifically, this reality
Apply in example, when signal of the operation result for the first level (low level), illustrate that trigger signal is believed for high level (second electrical level)
Number, illustrate that the output function of input unit is normal, so as to illustrate that the response function of processor breaks down, then export sign treatment
The configured information that the response function of device breaks down.Configured information in the present embodiment can also be indicator lamp information or word
Information.Such as, when operation result is the first level (high level), indicator lamp goes out, and represents that the response function of processor occurs
Failure, or directly with the information of word output " response function of processor breaks down ".
It should be noted that in the present embodiment, when signal of the operation result for second electrical level (high level), illustrating triggering
Signal is low level (the first level) signal, can now determine that the output function of input unit breaks down, and processor
Response function may the faulty event for being likely to no failure, the output function of input unit can first being processed in this case
Barrier, after failure to be released, if input equipment is not still responded to, is detected again, if operation result is the
During the signal of one level (low level), then illustrate that the response function of processor there is also failure, then can go to process processor again
Response function failure.
In addition, in the present embodiment, it is also possible to which it is high level to set the first level, and second electrical level is low level, and it is carried out
The principle of fault detect is identical, will not be repeated here.
The present embodiment in terms of existing technologies, when input equipment is not responded to, is incited somebody to action by logic with OR circuit
Feedback signal after the input signal and processor response of input equipment is accessed, and input equipment is judged by gate circuit comparative result
The specific guilty culprit not responded to, it is simple to operate, it is not necessary to which that professional is measured using special instrument, save artificial
Need not shut down the teardown of engine in cost and equipment cost, and detection process, will not damage machine.
The step of above method, divides, and is intended merely to describe clear, a step can be merged into when realizing or to certain
A little steps are split, and are decomposed into multiple steps, as long as comprising identical logical relation, all in the protection domain of this patent；
To adding inessential modification in algorithm or in flow or introducing inessential design, but its algorithm and stream are not changed
The core design of journey is all in the protection domain of the patent.
