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, can power after power supply plugs electricity for host CPU (an auto sleep function can be added herein, but
It is due to being socket power supply, so adding this function not necessary to quiescent dissipation is reduced), after opening ON/OFF main switch,
Host CPU starts self-test, and (liquid crystal display can all be shown full at this time, then be extinguished；It further needs exist for checking and leads to work due to having a power failure
Work times before interruption facilitate record), if self-test completion has, module is abnormal, and host CPU can drive buzzer to ring 3s, buzzing
W subgroup in the box of device in block diagrams indicates, if systems inspection is normal, can carry out further work.
Power supply circuit principle is mainly to give host CPU power supply through over commutation and again lowering and stabilizing blood pressure after passing through transformer pressure-reducing,
Added behind this circuit one with capacitor indicate backup power source, herein indicate one can charge and discharge compact battery.It sets herein
Setting to have a power failure in order to prevent causes system that cannot work on, if after having a power failure, this battery functions is powered to host CPU, electricity
Tankage selects that a switch is supported to work on 8000 times, that is, 3-4 hours enough as far as possible, but when having a power failure in order to prevent
Between it is too long, this battery design only works 3 hours, dormant state is entered after 3 hours, for the number such as storage switch work times
According to.
Model selection: model selection is by a simple resistance series-parallel circuit composition, as shown in the block diagram, by lower die
Formula 1 switchs, and the resistance value of CPU detection is R2+R3+R4, presses the switch of mode 2, and the circuit of CPU detection is R1+R3+R4, is pressed
Mode 3 switchs, and the circuit of CPU detection is R1+R2+R4, presses the switch of mode 4, and the circuit of CPU detection is R1+R2+R3, is passed through
Different resistance values is converted into electric signal in turn, and CPU can be identified and is ready for further work.
Selection of time: CPU recognition time selection mode be to be identified by counting, click then for setting ON when
Between, continuously double-clicking then is the time for setting OFF, and the setting of specific time is also to be grasped by key " upper and lower, left and right "
Make, if not pressing " upper and lower, left and right " key in 5s, the setting of system default this time.It should be noted that the selection of time
It can only can just operate after model selection completion, not so will call the police.
The setting of work times: good model is selected and after the time, so that it may which the selection for carrying out work times is also wanted here
After noticing that time, selection of time system default complete, by any one in lower button " upper and lower, left and right ", system is just opened
Begin to calculate the setting of work times, the setting of number is also to be realized with four keys, and it is upper and lower for+1 ,-the 1 of one digit number, a left side,
The right side is the movement of digit.This four keys, this numerical value of system default are not pressed in 5s.
After these steps are all set, operation can be realized by clicking operation, and in operation, system also will do it
It counts, different modes corresponds under different method of counting, such as mode 1, is suitable for wane type switch, then the first push rod of machine 31
After all working once with third push rod 33, count 1 time.Similarly to mode 4, details are not described herein for mode 2.
As shown in Figure 9 and Figure 10, the electricity for lasting purpose monitoring circuit being passed through for the judgement of switch fault mode, single-chip microcontroller
Stream realizes, if the electric current in observation circuit and selection mode and definition in the time are different, then program can judge automatically therefore
Barrier, and no longer count, the number that liquid crystal display is shown at this time, exactly switch the number that can correctly work.Time in program is shown
It is intended to as shown in figure 9, illustrating the sequence of different single-chip microcontroller pin output levels.Such as under mode 2, switch is self-locking
Switch, then switch contact closure, observation circuit has electric current to flow through at this time, complete in motor next time after the completion of motor action
Cheng Hou, switch disconnect, and do not have electric current in observation circuit at this time.As shown in figure 9, if switch contact closure after, under
After the completion of motor, still there is electric current to pass through, then switching at this time abnormal, illustrates to switch normally closed, inside is seized,
Control system 80 reports an error at this time.
The switch life-span detection device of the application, but in fact can also be further to having completed its function substantially here
Exploitation, such as monolithic processor controlled electronic switch are improved, since this switch is also to have working life, the service life can reach millions of
It is secondary, but if long-term use, the test (if 1W times) of several hundred switches can only be maintained, so here for the convenience of replacement
Property, can the internal small solid-state relay box for increasing a wiring, replacement can be dismantled 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-test, here there are six solid-state relay,
It abnormal sound 6 times, then represents and all breaks down, need whole replacements.
The foregoing is only a preferred embodiment of the present invention, is not intended to restrict the invention, for the skill of this field
