Module 35 is then for sending warning message when detection information is fault message, so that testing staff's timely learning is detected control
There are failures for the power supply of plate.
The application propose control panel power detector and system, control panel power detector include and tested observing and controlling
The signal relay of the power supply connection of making sheet, after host computer has sent detection request to the processing module of control board checking device,
Processing module sends detection instruction to relay control module, and relay control module then controls signal relay closure, so that
Level acquisition module has collected the power supply output of detected control panel, and processing module then can be based on the defeated of level acquisition module
Judge whether the power supply for being detected control panel is normal out, such as acquisition level is compared with preset reduced value, beyond fair
Perhaps range then shows that the power supply for being detected control panel is abnormal, is then showing the power supply of detected control panel without departing from allowed band just
Often, it is seen that based on the devices, systems, and methods that the application proposes, it is accomplished that the automatic detection to detected control panel power supply,
Detection information can be inquired in host computer, and detected control panel need to only be connect i.e. by testing staff with control panel power detector
Can, voltmeter detects without human intervention, is not necessarily to artificial judgment testing result, improves detection efficiency, and because without artificial
It participates in, also reduces the risk of detection, improve detection safety, solve existing control panel power detecting low efficiency and safety
Property difference technical problem.
Based on above-mentioned control panel power detector and system, the application also proposes a kind of control panel power detecting side
Method, using control panel power detector as executing subject, as shown in figure 3, including the following steps：
Step S31：Judge whether to receive detection request.
Detection request is sent by host computer, and detected control panel is connected with control panel power detector in testing staff
Afterwards, detection request is issued using host computer, if control panel power detector has received detection request,
Step S32：Detection instruction is sent to relay control module, so that relay control module is controlled based on detection instruction
Signal relay closure.
Relay control module is based on detection request, issues detection instruction, relay-operated controller one to relay-operated controller
Aspect is based on detection instruction control signal relay closure, on the one hand controls power relay closure and is embodied as being detected control
Plate powers on, so that the electric power output voltage of control panel is detected, so that level acquisition module can collect detected control panel
Power supply signal.
Step S33：It receives the output of level acquisition module and judges that the power supply output for being detected control panel is based on output
It is no normal.
After processing module receives the output of level acquisition module, the power supply output for being detected control panel is judged based on output
It is whether normal, specifically, presetting a fiducial value, acquisition level is compared with preset fiducial value, comparison result is in
In allowed band, then show that power supply is normal, surface power supply is abnormal if beyond allowed band, and preset fiducial value is according to reality
Application settings
When the power supply of detected control panel is multiple, it is defeated each power supply can be separately connected using control panel power detector
Realize automatic detection out, multiple signal relays be more preferably set in control panel power detector, each signal after
Electric appliance connects the power supply of a detected control panel, then correspondingly, step S32 is specially：To relay control module according to setting
The fixed multiple sub- detection instructions namely detection instruction of sequentially sending include multiple sub- detection instructions, and contain each self-test and refer to
The set information of execution sequence is enabled, so that relay control module, which is based on multiple sub- detection instructions, controls multiple signal relays
It is successively closed according to setting sequence, for processing module, when each signal relay is closed, all receives a level and adopt
Collect the output of module, processing module successively judges the output of each level acquisition module, judges to be detected control panel pair
Whether the power supply answered is normal, and the detection information judged every time is sent to host computer, including abnormal fault message, normally
Detection information and detection data etc..
Host computer judges whether detection information is fault message after receiving detection information, if so, to control panel electricity
Source detection device, which is sent, stops detection request.
Step S34：Judge whether to receive stopping detection request.
Control panel power detector monitors whether host computer sends stopping detection request after issuing detection information, if
No, then the detection procedure after carrying out, if so,
Step S35：It is sent to relay control module and stops detection instruction, so that relay control module is based on stopping detection
Instruction control signal relay disconnects.
The processing module of control panel power detector is sent out after receiving stopping detection request to relay control module
Stopping detection instruction being sent, on the one hand relay control module controls corresponding signal relay and disconnects, to terminate power detecting, separately
On the one hand, control power relay disconnect so that be detected control panel stop working, prevent power supply it is abnormal cause accident or
Failure.
Testing staff then can judge trouble power and power failure reason etc. according to detection information in time, to carry out in time
Maintenance.
The control panel power detector of above-mentioned the application proposition, system and method, in conjunction with control panel power detector
With jointly controlling for host computer, it is accomplished that the automatic detection to detected control panel power supply, detection information can be in host computer
Detected control panel need to only be connect by inquiry, testing staff with control panel power detector, without human intervention voltage
Table detection, is not necessarily to artificial judgment testing result, improves detection efficiency, and because participating in without artificial, also reduces detection
Risk improves detection safety, solves the technical problem of existing control panel power detecting low efficiency and safety difference.
It should be noted that the above description is not a limitation of the present invention, the present invention is also not limited to the example above,
The variations, modifications, additions or substitutions that those skilled in the art are made within the essential scope of the present invention, are also answered
It belongs to the scope of protection of the present invention.
