(3) content of the invention：
Many is arranged the present invention relates to Traditional Chinese medicine decocting room intelligence control system, on the desktop in Traditional Chinese medicine decocting room to boil medicine control
Device, electric medicine decocting tank put Chinese medicine and water into, and after sticking patient's mark, attaching plug may be inserted into control for decocting medicinal herbs control at any time
The pattern of boiling medicine is chosen on socket to start to boil medicine, then main controller input patient's identification code, main controller by RS232 interface with
Host computer compunlcation.General boil medicine begins with half an hour more than warm water soak period, then has very hot oven, slow fire phase etc., boils medicine
At the end of host computer computer pass through LED screen show patient's name.The power supply of electric medicine decocting tank is individually connected to system, and electric power is online outside,
And bidirectional triode thyristor is controlled to make to load energized power and time on its socket after being isolated by control for decocting medicinal herbs by photoelectronic coupler
By program operation of boiling medicine.Main controller and each control for decocting medicinal herbs are connected on same electric power cable and set master switch, in master switch
Be followed by rectifier diode, system is using half wave communication through power line and half-wave power supply, and in main controller and each control of boiling medicine
Cycle discriminator circuit is respectively mounted in device processed, for the synchronization time of generation system system is kept to keep strokes, while in its communication
One communications electronics switch and its switch drive module are respectively installed in circuit.When system communicates, all communications electronics switches are connected,
It is communicated by electric power cable, before sign off, turns off all communications electronics switches.
Communication is the master to keep main controller consistent with the communication operation long-term of each control for decocting medicinal herbs by control synchronization time
The switch drive module of control device and each control for decocting medicinal herbs is to be depressured from power network through resistance, just connecing diode and further isolate cycle
After negative half-wave, comparator input terminal is connected to, reference voltage is 100Mv to 200Mv, using diode drop through electric resistance partial pressure
It obtains, therefore the output terminal of comparator is square-wave signal, it generates corresponding electric power net week after the diode rectification just connect again
Ripple bears the positive square-wave signal of half-wave, is connected to the I/O mouths of microcontroller, traffic operation is performed when microcontroller scanning is to positive square-wave signal,
The positive square-wave signal is additionally operable to driving communications electronics switch, therefore communications electronics switch is turned off in cycle positive half-wave, and cycle is born
It is connected during half-wave.Communications electronics switch is connected to microcontroller corresponding port according to used communication mode, and carries out signal condition.
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 control for decocting medicinal herbs in realization system.
The cycle discriminator circuit structure diagram of main controller and each control for decocting medicinal herbs by two 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.
Two comparators are respectively used to screen point 1, screen point 2, as shown in Figure 1.In the cycle of cycle positive half cycle ascent stage
At zero passage, that is, screen point 0 set a voltage zero-cross detection module, it using cycle positive half-wave signal through electric resistance partial pressure, diode into
The clock end CLK of d type flip flop, the Q termination microcontroller external interrupts of d type flip flop are sent into after one step isolation negative half period, signal condition
Mouthful, which is arranged to level triggers, the D ends ground connection of d type flip flop, and S termination single-chip processor i/o mouths are usually put for the I/O mouthfuls
1.When cycle positive half-wave zero cross signal arrives, cycle signal rising edge immediately after makes d type flip flop Q ends be 0, outside microcontroller
Fracture low level in portion is interrupted so as to generate, executed instruction in interrupt service routine：Described I/O mouthfuls set to 0, the Central Shanxi Plain is broken, is counted
When, described I/O mouthfuls put 1, open interruption.Remaining two comparator is separately positioned on the cycle positive half cycle ascent stage, crest voltage
The examination point 1 at 35% to 50% place and the examination point 2 at 50% to 70% place.
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 for being arranged on d type flip flop in the voltage zero-cross inspection survey mould block ﹙ V0 ﹚ for screen point 0 jumps vanishing, production
It is raw to interrupt, record its zero crossing break period Th0；Hereafter, the output electricity of electricity pressure comparator ﹙ V1 ﹚ at point 1 is screened in microcontroller scanning
Pressure, when all wave voltages are reached to the threshold voltage of ﹙ V1 ﹚, output voltage saltus step from high to low, scanning records its bound-time Th1；
Similary scanning record screens electricity pressure comparator ﹙ V2 ﹚ output voltage bound-time Th2 at point 2, and Th0 and voltage zero-cross are detected mould
The output voltage bound-time setting value Ts0 of Kuai ﹙ V0 ﹚ makes comparisons；The output voltage bound-time of Th1 and electricity pressure comparator ﹙ V1 ﹚
Setting value Ts1 and Th2 makes comparisons respectively with the output voltage bound-time setting value Ts2 of electricity pressure comparator ﹙ V2 ﹚, if
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
During clock timer timing between cycle signal zero passage when this cycle signal zero passage and an adjacent preceding discriminator signal are true
Between Tzu, it is made comparisons with the average value Tz of cycle time, the cycle signal if no more than setting cycle time error Tzv
It is true, at this moment preserves Tzu and 20ms is taken to be added with synchrotimer timing time, in the value deposit synchrotimer that will add up.
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 voltage zero-cross Jian of point 0 surveys the output voltage saltus step of Mo Kuai ﹙ V0 ﹚, is interrupted so as to generate, and takes out the time of cycle voltage over zero
T0 is preserved, and clock timer is reset and starts timing, and at this moment cycle time voltage crosses zero Th0 is 0, while microcontroller is by above-mentioned
Method scans and judges discriminator signal.What it is due to detection is first cycle, and clock timer is opened in cycle voltage zero-cross
Beginning timing, the value of Th0, Th1 and Th2 must add the difference that cycle time 20ms subtracts out break period setting value Tk, such as
Three discriminator signals of fruit are true, and the time T0 of the cycle voltage over zero of taking-up is stored in as initial time in synchrotimer,
I.e. opening the break period for the first time takes Tk next time.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 saltus step, 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 inspection survey the non-saltus step of mould block ﹙ V0 ﹚ output voltages, 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, hereafter every time judge the cycle signal true and false, if false or this detection
Though discriminator signal is true but last time is false, then N is taken, will be restored after N+1 in memory, clock timer is not reset after interruption is opened
Continue timing, at this moment, next cycle of setting opens the break period and temporarily uses out break period interim setting value Tkz instead：
Tkz=(N+1) × Tz
Meanwhile next cycle closes break period temporary use instead and closes break period interim setting value Tnz：
Tnz=Tkz+Tns
When clock timer to after Tkz, the time that point is screened in scanning can be obtained by simple computation.If it at this moment examines
It is true to measure cycle signal, then takes out in memory N and preserve, and by N zero setting in memory, makes clock timer clocking value Ts
For：(Ts-Tkz) at this moment → Ts takes the value of (N+1) × 20ms to be added in synchrotimer, and recover using setting value Tks with
Tns, recovered clock timer are reset after interruption is opened.
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 bound-time
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, boil medicine due to main controller in system and respectively
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, using clock timer
Clocking value at Tkz is directly added in synchrotimer, to reduce the asynchronous time of system, power network normal operation situation
Lower N is much smaller than 25.
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.
