With self-inspection control port is forced, refrigerator electric control plate hardware system power-up initializing is examined to forcing self-inspection short circuit to emit state
Survey；When the port status for forcing self-inspection short circuit to emit do not force short circuit, then the judgement that hardware is voluntarily detected directly is jumped out, switched to
The normal refrigerating mode of step H；When the port status for forcing self-inspection short circuit to emit have forced short circuit, then the judgement behaviour of step B is carried out
Make；
If B, refrigerator electric control plate hardware system power-on time are more than one minute, the normal refrigerating mode of step H is switched to；If
Refrigerator electric control plate hardware system power-on time is not more than one minute, then carry out the judgement operation of step C；
C, reach at preset range and air door switch when each road sensor detection temperature value of refrigerator electric control plate hardware system
Under conditions of off-state, the peripheral hardware reset nought state started in self-check program enters step D；It is otherwise hard in refrigerator electric control plate
To be repeatedly detected in a minute of part system electrification and whether meet self-inspection condition, if meeting, any moment in one minute
Start self-check program；
D, startup optimization compressor simultaneously stop the operation of each transportation work style machine, are then shut off heater, illuminating lamp or other refrigerators
Load, original state zero position is switched to by motor-driven valve, magnetic valve, air door；
E, judge whether air door has been reset to zero position, the peripheral hardware load of step F is carried out if air door has reached zero position
Opening and closing operations；If air door does not reach zero position, control air door reaches zero position and then carries out the peripheral hardware load opening and closing of step F
Operation；
F, to all peripheral hardwares load carry out two break-make control operations in cycle, meeting the condition of electric-controlled plate power bracket
Under, by the unified open and close controlling of same type of load；

Embodiment two
As shown in figure 1, a kind of detection method for being applied to refrigerator electric control plate hardware system, including refrigerator electric control plate hardware system
System, its detection method is as follows：The electricity and under conditions of not possessing display board on first, forces self-inspection short circuit to emit shape according to current
State, door opening and closing state, each road sensor states judge whether refrigerator electric control plate is voluntarily detected function.Voluntarily testing conditions
Under, operation is opened and closed to all loads, so that it is determined that refrigerator electric control plate whether there is hardware fault, comprise the following steps：
1. pressure self-inspection control port is provided with electric-controlled plate, only just goes to judge self-inspection journey under the port short circuit state
Whether other conditions of sequence meet.The program has prevented user misoperation and has entered the possibility for voluntarily detecting.
2. door switch for door opening state be that electric-controlled plate enters one of condition for voluntarily detecting.The condition avoids self-check program
Action with commodity inspection program conflicts.
3. when electric-controlled plate goes up electricity for the first time, and self-inspection port, door switch, each road sensor states are forced to be satisfied by voluntarily detecting
Condition, electric-controlled plate starts execution hardware system and voluntarily detects.
4. reset all loads simultaneously, i.e.,：Motor-driven valve, magnetic valve, air door are reset to " zero original state ", close heating
Device, illuminating lamp, fan power supply.
5. after air door resets in place, start to be opened and closed handover operation to all peripheral hardwares.Should in the case of distinguishable
Shorten the execution time of the process as far as possible to improve detection efficiency.

As shown in figure 1, a kind of detection method for being applied to refrigerator electric control plate hardware system, including refrigerator electric control plate hardware system
System, comprises the following steps：
Step 1:After system electrification initialization, detected to forcing self-inspection short circuit to emit state immediately, when port status do not have
There is pressure short circuit, then directly jump out the judgement that hardware is voluntarily detected, switch to normal refrigerating mode.When port status have forced short
Connect, then carry out the judgement operation of Step 2.
Step 2:If the system electrification time is more than one minute, the state that self-inspection short circuit emits is removed by automatic, switched to normal
Refrigeration mode.Conversely, then carrying out the judgement operation of Step 3.
Step 3:When each road sensor detection temperature value reaches preset range, and the condition that door switch is off
Peripheral hardware reset nought state Step 4 in lower startup self-check program.To be otherwise repeatedly detected in a minute of upper electricity and whether met
Self-inspection condition, if meeting, any moment in one minute can start self-check program.
Step 4:Startup optimization compressor, stops the operation of each transportation work style machine, heater, illuminating lamp even load is closed, by electricity
Dynamic valve, magnetic valve, air door switch to original state zero position.
Step 5:Judge whether air door has been reset to zero position, the peripheral hardwares of Step 5 are carried out if air door has reached zero position
Load opening and closing operations.Must judge whether air door is reset to zero position, if air door does not reach zero position and just air door is opened
Closed operation will cause air door opening and closing angle anomaly occur.Testing staff understands the output of erroneous judgement electric-controlled plate hardware and exception occurs.
Step 6:2 break-make control operations in cycle are carried out to the load of all peripheral hardwares.Meeting electric-controlled plate power bracket
Under the conditions of, by the unified open and close controlling of same type of load.
Step 7:Hardware check process terminates, and removes the correlating markings of all process of self-test, is switched to according to conditions present
Normal refrigerating mode.
Presently preferred embodiments of the present invention is the foregoing is only, is not intended to limit the invention, it is all in essence of the invention
