Abstract
The quality determining method and device of a kind of drive signal of power-supply system of the present invention; its method be by before to power-supply system for forceful electric power light current come the process of the normal work of analog drive signal; whether normal test the drive signal simultaneously; if the drive signal is normal; just forceful electric power is supplied to power-supply system; it avoids supplying forceful electric power, and then protection switch pipe or other key elements for power-supply system in the case where drive signal generates exception.
Description
Technical field
The invention is related to a kind of test method, more particularly to a kind of quality testing of the drive signal of power-supply system
Method, this method are completed by establishing functional module construction by computer program instructions control computer system, these calculating
Machine program instruction stores in a computer-readable storage medium.
Background technology
Current power-supply system generally all using a large amount of switching tube, generally sends out driving letter by digital processing unit DSP
Number, which is driven into switching tube or other key elements after a series of conversion circuit is converted.
In the prior art, often there is a situation where switching tube or the damage of other key elements, the reason is that not having
It determines just directly to supply forceful electric power for power-supply system in the case of whether drive signal is normal, if drive signal is abnormal, then
It may result in switching tube or the damage of other key elements.
Invention content
The purpose of the invention is to provide a kind of quality determining method of the drive signal of power-supply system, and this method can be kept away
Exempt to supply forceful electric power, and then protection switch pipe or other key elements for power-supply system in the case where drive signal generates exception.
A kind of quality determining method of the drive signal of power-supply system is provided thus, it is characterised in that：To power-supply system
Before forceful electric power, first with light current come the course of normal operation of analog drive signal, while the drive is tested for light current to power-supply system
Whether dynamic signal normal, according to drive signal whether normally come decide whether to power-supply system supply forceful electric power.
Wherein, the light current before to power-supply system for forceful electric power carrys out the mistake of the normal work of analog drive signal
Journey specifically includes：
Step（1）：Judge the external command of simulation test, when detecting that external command meets the condition of simulation test,
It enters step（2）；
Step（2）：Power supply is judged, specifically, the power supply for judging supply power-supply system is forceful electric power or light current, if weak
Electricity then enables digital processing unit DSP send out drive signal, enters step simultaneously（3）；
Whether the test drive signal is normal, specifically including step（3）：Drive signal is transmitted to oscillography
Device judges whether the waveform of oscilloscope display is normal.
Wherein, step（1）In, specifically, the one of digital processing unit DSP I/O mouthfuls carried by the use of power-supply system as
Analog measurement interface when digital processing unit DSP detects that the level of analog measurement interface meets the condition of simulation test, enters
Step（2）.
Wherein, step（2）In, if forceful electric power, then alarm.
Advantageous effect：The quality determining method of the drive signal of a kind of power-supply system of the present invention, by giving power supply system
The process for the normal work for carrying out analog drive signal for light current before forceful electric power of uniting, while whether test the drive signal normal,
If the drive signal is normal, just avoided to power-supply system for forceful electric power in the case where drive signal generates exception as power supply system
System supplies forceful electric power, and then protection switch pipe or other key elements.
Specific embodiment
A kind of quality determining method of the drive signal of the power-supply system of the present embodiment be to power-supply system for forceful electric power it
Before, first to power-supply system for light current, with light current come the course of normal operation of analog drive signal, while test the drive signal and be
It is no normal, whether normally decide whether to power-supply system for forceful electric power that this method includes according to drive signal：
Step（1）：The external command of simulation test is judged, specifically, the digital processing unit DSP carried using power-supply system
One I/O mouthfuls as analog measurement interface, when digital processing unit DSP detects that the level of analog measurement interface meets simulation and surveys
During the condition of examination, enter step（2）；
Step（2）：Power supply is judged, specifically, the power supply for judging supply power-supply system is forceful electric power or light current, if weak
Electricity then enables digital processing unit DSP send out drive signal, enters step simultaneously（3）；If forceful electric power, then alarm；
Step（3）：Test driver signal specifically, drive signal is transmitted to oscillograph, judges the wave of oscilloscope display
Whether shape is normal, if normally, changing the level of analog measurement interface, exits simulation test, is then that power-supply system supplies by force
Electricity；If it find that the waveform of oscilloscope display has exception, then temporarily simultaneously repair circuit is detected first not to power-supply system for forceful electric power.
The present invention can avoid supplying forceful electric power, and then protection switch pipe for power-supply system in the case where drive signal generates exception
Or other key elements.
Method given herein, all or part of step therein can be by establishing functional module construction, by computer
Program instruction control computer system is completed.These computer program instructions store in a computer-readable storage medium.
