Letter device 750 reminds user, and the electricity of electrical appliance was broken automatically more than three days, does not allow electrical appliance long-time in holding state, keeps away
Exempt to cause an electric device due to the aging problem under standby of long-time.Judge whether to be in by detecting household electrical appliances electric current to treat
Machine state, as current family appliance standby electric current is between 1mA-10mA, therefore whether here is interval by judging electric current, you can judge
Household electrical appliances are in holding state.When specifically judging, process receives current value, and record current point in time and corresponding current value are to locally
Data base, carries out judgement current value, whether first judges current value more than 0.5 milliampere, if it is not, then determining whether new refreshing
Or reset, have, just sending out " not connecting load ", to mobile terminal, does not have, and continues to monitoring current.Determine whether new refreshing
Or the purpose of this action that resets is, this socket is constantly in when not connecting load, is only sent out and once " is not connected load " to shifting
Dynamic terminal, it is to avoid excessive to send information to user.If greater than 0.5 milliampere, then judge whether more than 10 milliamperesIf not,
Then it is considered to be in holding state during load.The standby time started is recorded, transmission is standby to be reminded to user, and by judgement is
No to have new refreshing or reset, only transmission is once standby reminds to user, lets the user know that this moment is holding state.Then
Detection, if whether keep in the standby state 72 hoursIf not, continue monitoring current, if it is, trigger relay/
Controllable silicon power-off, while sending out information, such as " stand-by time surpasses 3 days and automatically powers off " to mobile terminal.

During maximum current, that is, when reaching maximum current 90%, user is prenoticed, allow user to understand electricity consumption situation, it is corresponding so as to take
Measure, enhances your vigilance, and prevents the fire caused because of excessively stream." excessively stream early warning " specific workflow is as follows：When loaded work piece,
Judge that current value is more than 9 amperes(such as 5A), recorded local data base current value if not；If it is, judging whether again big
In 10 amperesIf not (such as 9.5A), and by determining whether new refreshing or reset, only send once standby prompting
To user, let the user know that this moment is excessively stream alarm condition.Current value recorded local data base.If (such as 11A),
Then trigger relay/controllable silicon power-off, while sending power-off reason is dealt into mobile terminal, and is sent to server current value and does
Record.
User start shooting by force under-voltage work 1 hour, overvoltage 1 hour specific workflow of work may be referred to it is as follows：
After under-voltage power-off, system can wait user to send power-on command by force.If receiving power-on command by force, judge
Whether less than the lower limit power-down value for setting, such as 150V if it is, continuing to remain powered off state, and sends " serious mistake to voltage
Break electricity " notify user.If it is not, then open relay or controllable silicon, monitoring work under undervoltage condition accumulative 1 hour or
After the duration of other settings, send out " under-voltage work power-off in 1 hour " and notify user, and trigger relay or controllable silicon power-off.
150V mentioned above, be according to obtained from the under-voltage working condition of the general purpose compressor of household electrical appliances air-conditioning and refrigerator,
, when working less than 150V, the probability caused danger is maximum, easily burns out compressor, therefore sets this 150V for compressor.
After over-pressed power-off, system can wait user to send power-on command by force.If receiving power-on command by force, judge
Whether more than the power-off higher limit for setting, such as 280V if it is, continuing to remain powered off state, and sends " serious mistake to voltage
Break electricity " notify user.If it is not, then open relay or controllable silicon, monitoring work under overpressure condition accumulative 1 hour or
After the duration of other settings, send out " overvoltage work power-off in 1 hour " and notify user, and trigger relay or controllable silicon power-off.
280V mentioned above, be according to obtained from the under-voltage working condition of the general purpose compressor of household electrical appliances air-conditioning and refrigerator,
, when working more than 280V, the probability caused danger is maximum, easily burns out compressor, therefore sets this 280V for compressor.
In some cases, power supply capacity is not enough, such as at peak times of power consumption, it may appear that extra low voltage (being less than 190V)
Situation, if now air-conditioning is not worked suddenly, can bring very burden, even if user knows that low pressure is caused, but user is also
It is intended to air-conditioning to work on, otherwise user is considered as air-conditioning poor quality.Therefore, user just has the demand started shooting by force.
After starting shooting by force, this programme also only allows continuous firing 1 hour, and then power-off plays a protective role.If used
Family still wants to allow air-conditioning to work on, then need to start shooting by force once again, and to remind user, this kind of working condition is risky
's.
When starting shooting by force, this programme is to monitor constantly temperature value and current value, and how temperature value and current value are exceeded, are
Can not start shooting by force, while user also can know the reason for can not starting shooting by force by mobile terminal.
