Make the pulse interface 93 power interface 92 being connected with power circuit being provided with panel 90 and being connected with impulse circuit.
The control method of the control system 80 of the switch life-span detection device of the application is explained below：
As shown in figure 5, after power supply plugs electricity, you can power for host CPU (herein can plus an auto sleep function, but
It is due to being that socket is powered, so adding this function not necessary to reducing quiescent dissipation), after opening ON/OFF main switch,
Host CPU starts self-inspection, and (now liquid crystal display can all show completely, then extinguishes；Further need exist for checking and lead to work due to having a power failure
Work times before interruption, convenient record), if to complete module abnormal for self-inspection, host CPU can drive buzzer to ring 3s, buzzing
W subgroup in device square frame in block diagrams represents, if systems inspection is normal, can carry out further work.
After power supply circuits principle mainly passes through transformer pressure-reducing, power to host CPU through over commutation and again lowering and stabilizing blood pressure,
This circuit followed by one with electric capacity indicate stand-by power supply, herein indicate one can discharge and recharge compact battery.Set herein
It has been set to and prevented power failure from leading to system can not work on, if after having a power failure, this battery functions is powered to host CPU, electricity
Tankage is tried one's best and is selected to support that a switch works on 8000 times, that is, 3-4 hour enough, but during in order to prevent power failure
Between long, this battery design only works 3 hours, 3 hours later enter resting state, for storage switch work times etc. number
According to.
Model selection：Model selection is by a simple resistance series-parallel circuit composition, as shown in the block diagram, presses mould
Formula 1 switchs, and the resistance value of CPU detection is R2+R3+R4, presses pattern 2 and switchs, and the circuit of CPU detection is R1+R3+R4, presses
Pattern 3 switchs, and the circuit of CPU detection is R1+R2+R4, presses pattern 4 and switchs, and the circuit of CPU detection is R1+R2+R3, passes through
Different resistance and then be converted into electric signal, CPU can identify and be that further work is ready.
Selection of time：The pattern that CPU recognition time selects is by counting identifying, click be then set ON when
Between, continuously double-clicking is then the time setting OFF, and the setting of specific time is also to be grasped by button " upper and lower, left and right "
Make, if not pressing " upper and lower, left and right " button in 5s, system default this time sets.It should be noted that the selection of time
Just can only can operate after model selection completes, not so can report to the police.
The setting of work times：Select good model and after the time it is possible to be operated the selection of number of times, also will here
Note the time, after selection of time system default completes, pressing the button any one in " upper and lower, left and right ", system is just opened
The setting of beginning evaluation work number of times, the setting of number of times is also to be realized with four buttons, and upper and lower is+1 ,-the 1 of same one digit number, left,
The right movement for digit.This four buttons, this numerical value of system default is not pressed in 5s.
After these steps all set, click on to run and just can realize operating, in operation, system also can be carried out
Count, the different method of counting of different pattern correspondences, such as pattern 1 time is it is adaptable to wane type switch, then machine the first push rod 31
After all working once with the 3rd push rod 33, count 1 time.Pattern 2 to pattern 4 in the same manner, will not be described here.
As shown in Figure 9 and Figure 10, for the judgement of switch fault pattern, single-chip microcomputer is by the electricity of lasting purpose monitoring circuit
Stream realizing, if the electric current in observation circuit is different with the definition in the time with the pattern of selection, then program can automatic decision former
Barrier, and no longer count, the number of times that now liquid crystal display shows is it is simply that switch the number of times that can correctly work.Time in program is shown
It is intended to as shown in figure 9, illustrating the order of different single-chip microcomputer pin output levels.Such as under pattern 2, switch is self-locking
Switch, then after the completion of motor action, switch contact closes, and now observation circuit has electric current to flow through, complete in upper once motor
Cheng Hou, switches off, and does not now have electric current in observation circuit.If as shown in figure 9, switch contact closure after, under
After the completion of motor, electric current is still had to pass through, then now to switch abnormal, illustrate that switch is normally closed, inside is seized,
Now control system 80 reports an error.
The switch life-span detection device of the application to substantially having completed its function here, but in fact can also be further
Improve exploitation, such as monolithic processor controlled electronic switch, because this switch is also to have working life, the life-span can reach millions of
Secondary, but if long-term use, the test (if 1W time) of hundreds of switch can only be maintained, so herein for the convenience changed
Property, can the internal little solid-state relay box increasing a wiring, replacing can be taken apart if broken down, the output of electronic switch is all
There is single-chip microcomputer detection circuit, if be broken, system can drive buzzer abnormal sound in self-inspection, has six solid-state relays here,
Abnormal sound 6 times, then represent and all break down, and needs all to change.
The foregoing is only the preferred embodiments of the present invention, be not limited to the present invention, for the skill of this area
For art personnel, the present invention can have various modifications and variations.All within the spirit and principles in the present invention, made any repair
Change, equivalent, improvement etc., should be included within the scope of the present invention.
