Description
Technical field
The present invention relates to power technique fields, particularly a kind of fault alarm method of the power supply of programming.
Background technology
Programming power supply refers to that some function or parameter can be by the power supplys of computer programming control, for example arrange electric power output voltage for how many, maximum output current be how many etc. can realization by programming.Because programming power supply can be according to user's request regulation output constant voltage or steady current, the application of power of therefore programming is extensive.
Programming power supply there will be various faults unavoidably through long-term use, causes its cisco unity malfunction.In the time that programming power supply breaks down, conventional fault alarm mode is at present, on the operation screen of programming power supply, pilot lamp is set, and carries out fault alarm by the continuous flicker of pilot lamp.The power of pilot lamp is conventionally less, and light is faint, therefore carries out fault alarm by this kind of mode, a little less than indication ability, if do not have the timely discovery power supply that will cause programming to quit work for a long time.
Summary of the invention
The object of the invention is to, for the poor problem of programming power fail alert capability existing in prior art, provides a kind of fault alarm method of the power supply of programming.
In order to realize foregoing invention object, the invention provides following technical scheme:
The fault alarm method of programming power supply, comprises the following steps:
Step 1: carry out primary fault detection every setting a period of time, judge whether present clock programming power supply breaks down, if broken down, carries out malfunction storage, and enters step 2, otherwise wait for that next clock failure detects;
Step 2: judge that whether last clock programming power supply breaks down, and if not entering step 3, otherwise returns to step 1;
Step 3: the fault alarm picture that output prestores, described fault alarm picture covers the operation screen display page of whole programming power supply.
Preferably, in described step 2, the display mode of fault alarm picture is: multiple fault alarm picture circulation outputs, every a fault alarm picture of setting-up time output, the fault alarm picture of current time output covers the fault alarm picture of previous moment output.
compared with prior art, beneficial effect of the present invention: fault alarm method of the present invention, if present clock programming power supply breaks down and last clock does not break down, export the operation screen display page that fault alarm picture covers whole programming power supply, than pilot lamp, the mode that whole operation screen display page covers fault alarm picture is more easily found, warning function is stronger, is convenient to staff and timely the programming power supply breaking down is carried out to fault eliminating.The fault alarm picture that the mode of multiple fault alarm picture circulation outputs covers whole operation screen presents dynamic show state, has further strengthened warning function.Fault alarm method of the present invention is particularly useful for the equipment with touch screen, has avoided the setting of pilot lamp.
Accompanying drawing explanation:
Fig. 1 is fault alarm method process flow diagram in embodiment.
Embodiment
Below in conjunction with test example and embodiment, the present invention is described in further detail.But this should be interpreted as to the scope of the above-mentioned theme of the present invention only limits to following embodiment, all technology realizing based on content of the present invention all belong to scope of the present invention.
With reference to figure 1, the fault alarm method of programming power supply provided by the invention, comprises the following steps:
Step 1: every setting a period of time, for example, carry out primary fault detection every 100ms, judge whether present clock programming power supply breaks down, if broken down, carries out malfunction storage, and enters step 2, otherwise wait for that next clock failure detects.
Step 2: judge that whether last clock programming power supply breaks down, if programming power supply does not break down at last clock, enters step 3, otherwise returns to step 1.
It should be noted that, in fault personnel find to programme the operation screen of power supply, demonstrate after fault alarm picture, can know that programming power supply breaks down, need to get rid of programming electric power incoming line fault.Fault personnel, in the time carrying out fault eliminating, first exit the fault alarm page by button, show default page, and fault normally shows by reset key recovery operation screen after getting rid of again.Because the time interval of fault detect is 100ms, fault is got rid of required time much larger than 100ms, therefore during fault is got rid of, is also carrying out fault detect.Because fault is not got rid of, therefore testing result is still that programming power supply breaks down, if now export fault alarm picture, can affect staff's troubleshooting effort, therefore need to avoid by this step the generation of this class situation, only primary fault get rid of just carry out after finishing on fault alarm once, that is to say, only do not break down at last clock, in the situation that present clock breaks down, just carry out fault alarm.If fault personnel do not carry out fault eliminating in time after carrying out fault alarm, operate so screen and can show fault alarm picture always, until staff exits the fault alarm page by button.Even do not fix a breakdown in time after therefore breaking down, also can keep fault alarm, when next clock detection is not but carried out fault alarm (because present clock breaks down), the problem that yet can not cause fault alarm to omit to breaking down always.In troubleshooting process, in order to keep fault alarm prompting, exiting by button after the fault alarm page, on default page, fixed position shows a warning mark, in order to point out user at present still in fault-alarming state, warning mark is just clear after fault is got rid of laggard horizontal reset.
Step 3: the fault alarm picture that output prestores, fault alarm picture covers the operation screen display page of whole programming power supply.In order to strengthen display effect, strengthen warning function, in fault alarm picture, can show printed words such as " power fails ", fault alarm picture can also comprise multiple gorgeous color.
In this step, the fault alarm picture of output is one, after this fault alarm picture output, cover the operation screen display page of whole programming power supply always, until staff carries out reset operation or got rid of fault by other means, the operation screen display of programming power supply is shown normal working interface.In order further to strengthen warning function, the fault alarm picture of exporting in this step is multiple, multiple fault alarm picture circulation outputs, for example, every a fault alarm picture of setting-up time (0. 1ms) output, the fault alarm picture of current time output covers the fault alarm picture of previous moment output, makes fault alarm picture present dynamic show state.
The inventive method is applicable to the various equipment with display screen, and the especially equipment with touch screen is not limited to the programming power supply described in embodiment.
