The present invention utilizes the positive half cycle ascent stage of power network cycle, takes three to screen point and realize and the identification of cycle signal is sentenced
It is fixed, the cycle time is recycled to establish synchronization time, the synchronous operation of main controller and each appliance controller in realization system.
The cycle discriminator circuit structure diagram of main controller and each appliance controller by three as shown in Fig. 2, use hysteresis
The voltage comparator of comparator forms, comprising filter circuit, the reference voltage of voltage comparator in each voltage comparator
It is provided by regulator circuit.System sets clock timer and synchrotimer.If detect that two adjacent cycle signals are equal
It is true, then takes out the clock timer timing time between this two adjacent cycle signal zero passages, is sequentially stored in the cycle time
In storage unit, which can store 100 cycle times, a cycle time is often stored in when being filled with,
The cycle time being stored at first is first removed, and calculates the average value Tz of the cycle time of deposit and preserves, is reflected using Tz values
Cycle signal not to be identified reduces erroneous judgement possibility to reduce the influence of power network frequency fluctuation, while screen point using three.
Three comparators are respectively used to three examination points, that is, screen point 0, screen point 1, screen point 2, as shown in Figure 1.In week
At the cycle zero passage of ripple positive half cycle ascent stage, that is, screen point 0 and voltage zero-crossing comparator is set, due to power network cycle negative half period quilt
Rectifier diode is isolated, in order to improve accuracy of detection, in the signal input part series diode isolation again of voltage zero-crossing comparator
Negative half period, reference voltage is increased to 10mv to 100mv from zero, and depending on the offset voltage of comparator, which can profit
It is obtained with diode drop through electric resistance partial pressure.Remaining two comparator is separately positioned on cycle positive half cycle ascent stage, crest voltage
35% to 50% place examination point 1 and 50% to 70% place examination point 2.
Cycle signal determining：After setting time opens interruption, clock timer resets and starts timing microcontroller, works as cycle
During voltage zero-cross, the output voltage overturning for the voltage Zero-cross comparator Qi ﹙ V0 ﹚ for screening point 0 is arranged on, is generated in its voltage trailing edge
It interrupts, records its zero crossing break period Th0 and the Central Shanxi Plain is broken；Hereafter, electricity pressure comparator ﹙ V1 ﹚ at point 1 are screened in microcontroller scanning
Output voltage, when all wave voltages are reached to the threshold voltage of ﹙ V1 ﹚, output voltage is overturn from high to low, when scanning records its overturning
Between Th1；Similary scanning record screens electricity pressure comparator ﹙ V2 ﹚ output voltages flip-flop transition Th2 at point 2.By Th0 and voltage zero-cross
The output voltage flip-flop transition setting value Ts0 of Bi compare Qi ﹙ V0 ﹚ makes comparisons；The output voltage of Th1 and electricity pressure comparator ﹙ V1 ﹚ are overturn
Time setting value Ts1 and Th2 makes comparisons respectively with the output voltage flip-flop transition setting value Ts2 of electricity pressure comparator ﹙ V2 ﹚, such as
For fruit in the range of allowable error, then the discriminator signal detected is true, is otherwise false.When above-mentioned judgement discriminator signal is true,
Calculate the clock timer meter between cycle signal zero passage when this cycle signal zero passage and an adjacent preceding discriminator signal are true
When time Tzu, it is made comparisons with the average value Tz of cycle time, the cycle if no more than setting cycle time error Tzv
Signal is true, at this moment preserves Tzu and 20ms is taken to be added with synchrotimer timing time, the value deposit synchrotimer that will add up
In.
When clock timer starts timing with cycle voltage zero-cross, then timing to 16ms opens the break period between 18.5ms
Open interruption during setting value Tk, clock timer timing to 25ms to Central Shanxi Plain during pass break period setting value Tn between 27ms is broken.
After system boot, clock timer starts timing, when detecting first cycle voltage zero-cross, is arranged on examination
The output voltage overturning of the voltage Zero-cross comparator Qi ﹙ V0 ﹚ of point 0, interrupts so as to generate, takes out the time T0 of cycle voltage over zero
It preserves, clock timer is reset and starts timing, at this moment cycle time voltage crosses zero Th0 is 0, while microcontroller presses above-mentioned side
Method scans and judges discriminator signal.What it is due to detection is first cycle, and clock timer is started in cycle voltage zero-cross
Timing, the value of Th0, Th1 and Th2 must add the difference that cycle time 20ms subtracts out break period setting value Tk, if
Three discriminator signals are true, and the time T0 of the cycle voltage over zero of taking-up is stored in as initial time in synchrotimer, under
Once i.e. opening the break period for the first time takes Tk.Otherwise for fictitious time, at this time the clock timer time must add T0, continue to detect.
When detecting first and second adjacent cycle voltage zero-cross, due to not preserving the cycle time of detection,
Therefore the clock timer timing time twice between cycle signal zero passage is made comparisons with cycle time 20ms, judges cycle signal
Then it is that the difference that 20ms is taken to subtract Th0 is added with synchrotimer timing time when being true, i.e., preserves the standard cycle time for the first time
20ms need to deduct its Th0 value, this is because when hereafter to detect cycle signal every time be true, by clock meter when opening interruption
When device reset after restart timing, and be that the standard cycle time is included in synchrotimer when opening interruption, open interruption
Afterwards clock timer reset, otherwise judge cycle signal be fictitious time, at this time the clock timer time must add T1=T0+Tk, after
It is continuous to detect first cycle again as stated above.After it is very to detect first cycle signal, recover above-described cycle
Signal determining.
If as shown in Figure 1, detecting that cycle signal is false, the break period is opened next time and opens the break period at this
Afterwards, open interruptions during average value Tz through the cycle time that is delayed, and open interrupt after be delayed Tns when the Central Shanxi Plain break, when setting the Central Shanxi Plain to break
Between be when cycle signal screen point 0 when do not generating interruption, at this moment must be in the setting time point more than Ts0 allowable error scopes
When starting to scan and scanning examination point 1 and screen point 2, voltage comparator output voltage does not generate overturning, all breaks in the Central Shanxi Plain
Scanning is broken and is stopped in the time Tns Central Shanxi Plain, and Tns is:
Tns=Tn-Tk
If it is true to detect cycle signal, next cycle opens break period Tks and is:
Tks=Tk+Th0
I.e. from opening for the first time after the break period takes Tk, clock timer is that timing opens interruption to Tks, and weight after resetting
New to start timing, timing is broken to Central Shanxi Plain during Tns, so that the synchrotimer time is corrected be subject to cycle time voltage crosses zero.
It repeats the above process.If the upper cycle signal detected is true, when this cycle judges, discriminator signal is
Vacation or the cycle time detected are more than setting cycle time error Tzv or clock meter compared with the average value Tz of cycle time
When device timing to close break period setting value Tns when, voltage Zero-cross comparator device ﹙ V0 ﹚ output voltages are not overturn, in not generating
Disconnected, then when clock timer timing is to Tns, the Central Shanxi Plain is broken, and at this moment remembers that not counting cycle N is 1 and stores, when opening interruption next time
Between be to open the break period in last time to open interruption after Tz, clock timer open interrupt after reset and timing, when timing is to Tns
The Central Shanxi Plain is broken, and hereafter judges the cycle signal true and false every time, though if false or this detection discriminator signal be false true last time, then take
N will be restored after N+1 in memory.
When it is true to detect cycle signal, then takes out N in memory and preserve, and by N zero setting in memory, and recover to make
With setting value Tks, the value of (N+1) × 20ms is at this moment taken to be added in synchrotimer.
The system synchronization time be synchrotimer time, along with currently just timing clock timer time.
When judging to screen the point signal true and false, Th0, Th1, Th2 are by being set with voltage comparator output voltage flip-flop transition
Definite value Ts0, Ts1, Ts2 make comparisons see it is whether overproof, come judge screen point a signal true and false, can select：Th0, Th1, Th2 are
The cycle discriminator signal is true when true or Th0 is true, while when one of Th1, Th2 are true or when Th1, Th2 are true, it should
Cycle discriminator signal is true, depending on to judging the different requirements of the cycle signal true and false.
If system fault, when N is more than a setting value between 25 to 70, due to main controller in system and each electric appliance
Controller, Tz values and the N values of detection may be different, at this moment, power network frequency accumulated error, when may cause synchrotimer
Between corrected when can not be by detecting true cycle signal, when it is true to detect cycle signal, at this moment using clock meter
When device accumulative clocking value be directly added in synchrotimer, to reduce the asynchronous time of system, add up clocking value be N × Tz
+20ms.N is much smaller than 25 in the case of power network normal operation.
The cycle time error Tzv of permission and the flip-flop transition setting value of voltage comparator output voltage, by test assessment
Its average value is taken to obtain.
