Since trigger signal is by external input, since existing signal interference is different under a variety of occasions, because
If this is using unified trigger condition detection method, it is likely that false triggering or leakage triggering occurs, to solve the problems, such as this, needs
The setting of trigger sensitivity is introduced, makes user and different sensitivity levels is selected according to the application scenario of oneself, avoid false touch
Hair or leakage triggering.Realize that the adjustable method of trigger sensitivity generally there are two kinds：First, noise is suppressed by hardware filter,
So as to remove undesirable trigger signal；First, being realized by software for jitters elimination, realized by setting different the delay for eliminating the signal-wobble
Different trigger sensitivities.Higher by the method cost of hardware and implementation is complicated, application example of the present invention is using soft
Part disappears the method trembled to increase the selection of trigger sensitivity., need not to filter by increasing a trigger sensitivity setting unit
The triggering wanted, for the time for the effective trigger signal for receiving current time when receiving trigger signal with the last time
Interval, compared with the disappearing and tremble the time of user setting, if time interval is more than described disappear and trembles the time, judgement is currently received
Trigger signal is effective trigger signal；IOx triggers input inquiry unit 31 when the enabled I/O port makees triggering input, according to
Effective trigger signal monitors whether to meet trigger condition.Trigger sensitivity is divided into high, medium and low three ranks, each rank
Correspond to one respectively to disappear and tremble the time, high sensitivity disappears, and to tremble the time most short, and muting sensitivity disappears, and to tremble the time most long.Increase trigger sensitivity
Triggering input module block diagram after setting unit is as shown in fig. 7, be application example of the present invention to the 2nd improved increase of Fig. 3
The triggering input module block diagram of trigger sensitivity setting unit 38.
When setting the trigger sensitivity of triggering input module, difference is gone out according to the high, medium and low level conversion that user selects
Disappear and tremble the time, behind when periodically inquiring effective trigger condition, trembled the time with disappearing and filtered out, as shown in figure 8, should for the present invention
The schematic diagram selected with example Fig. 4 increase trigger sensitivities.The following judgement of [A] place increase i.e. in figure 6 can be achieved：Sentence
The current time minus last that disconnecting receives trigger signal receives the time effectively triggered, and whether obtained time interval, which is more than, disappears
Tremble the time；If so, then receive effective triggering；If it is not, effective triggering is not received then.
In some application scenarios, user may need that the output of each passage of instrument is in turn switched on or broken successively
Open；Other occasion, user may also need to that more instruments can be connected or disconnected according to certain sequential.Both occasions
Using, can by increasing output control delay unit in input module is triggered, for after the trigger condition is met,

Add the triggering input module block diagram after output control delay unit as shown in figure 9, changing for the 3rd time to Fig. 3 for application example of the present invention
Into the triggering input module block diagram of rear increase output control delay unit 39.
Application example implementation method of the present invention is very simple, is that application example of the present invention increases delay to Fig. 4 as shown in Figure 10
The schematic diagram of control.The following processing of [B] place increase in figure 6 is only needed to can be achieved：It is not 0 to judge whether delayIf so, then
Step 613 is performed after delay process；If it is not, then directly perform step 613.
Application example of the present invention can realize that the output of each passage is connected or broken according to specified sequential using delay function
Open, can also realize that more linear power supplies are powered on or powered off according to specified sequential, be application example of the present invention as shown in figure 11
Receive the schematic diagram of each passage of Time Delay Opening after effectively triggering：After receiving effective trigger signal, CH1 is not delayed, and directly beats
Open walk exports；Passage output is opened after CH2 delays 1s, passage output is opened after CH3 delays 2s, is opened after CH4 delays 3s logical
Road exports.
Detection in the application example above method of the present invention to trigger condition is software by periodically inquiring about each I/O port
Come what is realized, this inquiry mode has the disadvantage that level state：
1st, real-time is inadequate, and there are the error of a polling cycle；
2nd, software, which constantly inquires about I/O port state, can increase the load of processor.
Application example of the present invention can further improve above-mentioned implementation method, with interruption to improve above-mentioned two point defect
The method of method replacement query is realized.I/O port is set as interrupt source（Some par-ticular processors are just supported）, and according to user
The triggering type of setting is to set high level triggering to interrupt, low level triggering is interrupted, rising edge triggering is interrupted or trailing edge touches
Hair interrupts（Some par-ticular processors are just supported）.In interrupt function, disappear and tremble processing and realize that trigger sensitivity can set work(
Energy.Interrupt mode is specifically that interrupt handling routine is placed on to the entrance of respective interrupt vector, and kernel detects that interrupt condition meets
Afterwards, the interrupt handling routine of the inlet is called automatically, and triggering input processing is carried out in the processing routine.In waiting process
In, software is without any action.And inquiry mode is exactly every how long going to look into once, it is necessary to which software timing is done on software
It is living.Due to being realized by the hardware interrupts of processor, so will not substantially have a high regard for when trigger condition is waited to processing
What extra duty, once and hardware meets trigger condition, then can call interrupt function automatically.After making interrupt mode realization into, only
Need when setting the various parameters of triggering input to set processing more than [A] place in Fig. 6 to hardware register, and
The part below [A] flow is called in interrupt function.
In the following, triggering output is specifically described：
As shown in figure 12, output module block diagram is triggered substantially for application example of the present invention.Application example of the present invention will be realized
Output function is triggered, a CHx output states control unit 121 is at least needed, for setting the triggering bar of trigger output signal
Part, the trigger output signal generally when opening analog channel output；On power supply is applied there may be more power supplys need according to
Certain sequential powers on, user can when controlling some passage of certain linear power supply to open, using triggering input/output function,
Realize that more linear power supplies open output according to certain sequencing, to make load obtain voltage according to specified order.Its
In, x is the distinguishing identifier of each difference CH passages in this triggering exports application example, and minimum value can use 0, and maximum can use instrument
The CH channel numbers that device is supported.Since the direction of common I/O port is semiduplex, cannot be inputted when exporting, when inputting not
It can export, it is contemplated that to be provided simultaneously with triggering and output and input function, therefore at least also need to an enabled control unit
123, come enable corresponding I/O port do triggering input with or triggering output use；In addition, it is also necessary to which an IOy triggers output control list
Member 122 is used to, when enabled I/O port makees triggering output, judge whether the output of passage meets the trigger condition, and according to judgement
The corresponding I/O port of output control produces trigger output signal；Wherein, y is each different I/O ports in this triggering exports application example
Distinguishing identifier, minimum value can use 0, and maximum can use the I/O port number of instrument support and the minimum value of analog output channel number.
The block diagram of above-mentioned basic triggering output module realizes that flow is as shown in figure 13, is triggered substantially for application example of the present invention
Output module realizes flow chart.X minimum values can use 0 in above-mentioned flow chart, and maximum can use the CH number and mould of instrument support
Intend the minimum value of output channel number.Each I/O port realizes triggering output work according to above-mentioned flow with a relatively independent function
Can, specifically include：
1301st, start；
1302nd, judge whether to open CHx outputs：If so, turn 1303；If it is not, turn 1305；
1303rd, it is enabled to judge whether IOy triggers output：If so, turn 1304；If it is not, turn 1305；
1304th, IOy is made to export high level；
1305th, IOy is made to export low level；
1306th, terminate.
In above-mentioned realization, there are the following problems：
1st, the triggering output of all I/O ports only one is enabled, and when enabled after, all I/O ports of instrument are each configured to trigger defeated
Go out function；
2nd, when needing to export trigger output signal, acquiescence output high level, does not support to set；
3rd, CHx acquiescences control corresponding IOy, are to correspond, and do not support modification correspondence.
Application example of the present invention for it is above-mentioned some make following improvement：As shown in figure 14, it is application example pin of the present invention
To the 1st improved basic triggering output module block diagram of Figure 12.
1st, enabled control unit 123 is improved to individually enable control unit 124, exports the triggering of each I/O port and enable
It can be independently arranged；
2nd, a trigger output signal type selection unit 126 is increased, it is square wave or electricity that trigger output signal, which may be selected,
Ordinary mail number, when analog channel is exported and closed, triggering output low level（User can set respective channel to input by front panel
Export, on software after analog channel action of configuration has been performed, then perform triggering output control action）, when analog channel exports
During opening, the high level or square wave of triggering output user setting；
3rd, the correspondence selecting unit 125 of CHx and IOy is increased, you can with the passage of selection control IOy outputs, it is not necessary to
Force to correspond, such as, voltage inputs of the CH0 as two trigger output signal lines of IO0, IO3 can be selected.
In the improved triggering output module block diagram figure 14 above of application example of the present invention x minimums can value be 0, maximum is desirable
It is worth the port number for instrument；Y minimums can value be 0, it is maximum can value be instrument I/O port number.The correspondence of CHx and IOy
Selecting unit 125 supports multiple selection modes, i.e., same passage can control multiple I/O ports, for example, can set CH0 control IO0,
IO2 etc..If I/O port number is 4, then the controllable I/O ports of CH0 are combined as C (4,1)+C (4,2)+C (4,3)+C (4,4), totally 15 kinds
Combination, has expanded the combination of the controllable trigger output signal of each passage significantly.
