Preferably, the present embodiment also provides a kind of working method based on camera flashing light HUB device, including following
Step:
Step S1: after device is powered on, tetra- signal wires of described single-chip microcontroller P3.3, P3.4, P3.5, P3.7, control is
First analog switch that is electrical connected, the second analog switch, third module switch, the 4th analog switch A, B, C, INH
Signal completes the selection for four analog switch channels, and then completes the selection for 8 hot shoes, thus
Sequence reads the state of connected eight flash lamps of eight hot shoes, selects one group to complete the flash lamp wired back, and
By the state transfer of selected flash lamp to the digital comparator；
Step S2: first hot shoe contact, the second hot shoe contact, third hot shoe contact and the 4th hot shoe contact respectively according to
Four comparison data input pins of the secondary connection digital comparator, the current state to provide currently selected middle flash lamp are believed
Number；
Step S3: before photography shutter is pressed, single-chip microcontroller is transferred to the number of the digital comparator in the step S1
It is equal according to the data for being transferred to the digital comparator with four hot shoe contacts, the QA=B of the digital comparator at this time
End output high level；When photography shutter is pressed, then four hot shoe contacts are transferred to the data in the digital comparator
It changes；Four hot shoe contacts described in step S2 are transferred to single described in data and step S1 in the digital comparator
The data that piece machine is transferred to the digital comparator are unequal, and the end QA=B of the digital comparator exports low level, under generation
Drop sends interrupt request singal along jump, Xiang Suoshu single-chip microcontroller；
Step S4: after the single-chip microcontroller receives interrupt request singal, again by P1.4, P1.5 of the single-chip microcontroller,
Tetra- mouth lines of P1.6, P1.7 read the state of the corresponding hot shoe contact, and judge whether to complete according to the state of contact signal
Normal flash of light, and control the selection that another flash lamp for completing to wire back is completed in four hot shoe contacts.
Preferably, in the present embodiment, 48 are selected the public output of 1 analog switch to connect 4 of camera machine top hot shoe
Contact.And the 4 tunnels control signal of each hot shoe is then respectively from the same road terminal of 4 analog switches.Specific flash of light
Whether the hot shoe of lamp and which flash lamp, which are connected, depends on tri- control lines of analog switch control signal A, B, C, and specifically connect
General rule suspension control signal INH control, A, B, C control line and INH then by the control of MCU, complete relevant flash lamp selection and connect
Logical, specific control signal is as follows:
| INH | C | B | A | Connect flash lamp |
| 0 | 0 | 0 | 0 | Flash lamp 1 |
| 0 | 0 | 0 | 1 | Flash lamp 2 |
| 0 | 0 | 1 | 0 | Flash lamp 3 |
| 0 | 0 | 1 | 1 | Flash lamp 4 |
| 0 | 1 | 0 | 0 | Flash lamp 5 |
| 0 | 1 | 0 | 1 | Flash lamp 6 |
| 0 | 1 | 1 | 0 | Flash lamp 7 |
| 0 | 1 | 1 | 1 | Flash lamp 8 |
| 1 | x | x | x | Disconnect all flashing lights |
Preferably, the present embodiment also introduces digital comparator and single-chip microcontroller, ATEL company is used in the present embodiment
AT89C4051, digital comparator then select 74HC85.Circuit as shown in Figure 1, digital comparator 6 feet, that is, equal instruction
Terminate the P3.2 of MCU, that is, external interruptInterrupt request singal line, when two groups of input numerical value of digital comparator
A failing edge is exported when not identical, requests to interrupt service to MCU.
It will be seen from figure 1 that the selection of specific flash lamp is controlled by control line P3.3, P3.4, P3.5, P3.7 tetra-
What line was completed, after device powers on, selection flash lamp 1 can be defaulted as, at this time by process control, by P1.4, P1.5,
Tetra- butt mouth line of P1.6, P1.7, MCU read the state of 4 mouth lines of flash lamp, in the wait state, the state of this 4 mouth lines
Be it is fixed, the state of this 4 mouth lines is sent to digital comparator by the way that tetra- root port of P1.0, P1.1, P1.2, P1.3 is counter by MCU
A0, A1, A2, A3, that is, one group of digital comparator compares data input pin；4 contacts status of camera hotshoe are simultaneously
It is also coupled to B0, B1, B2, B3 of digital comparator, that is, another group of input data of digital comparator.It is sent out in no flash of light
Raw situation, two groups of data are equal, and the signal of the output of QA=B is high level.When camera shutter is pressed, then hot shoe
On data can change, cause two groups of data unequal, thus QA=B export low level, to MCU issue interrupt requests.
MCU breaks in the response after request signal, and judgement completes normal flash of light, then passes through P3.3, P3.4, P3.5, P3.7 tetra- controls
Line processed makes camera hotshoe complete the selection of another flash lamp.
In realizing control, powering on rear MCU also and should carry out first the flash lamp in primary each channel, there are situations, skip not
There is installation flash lamp channel, does not choose the hot shoe channel for being fitted without flash lamp in later work.
Preferably, the present embodiment includes the hot shoe of eight same brand flash lamps, a phase for possessing 4 hot shoe contacts
Machine flash lamp connection terminal, four models identical 8 select 1 analog switch, single-chip microcontroller and digital comparator；Device power on
Afterwards, single-chip microcontroller reads the state of each flash lamp, and state is transmitted to one group of digital comparator to compare data input pin (former
State)；Meanwhile 4 contacts status of camera hotshoe are connected to another group of input data end of digital comparator；It is completed in flash lamp
In the state of telegram in reply, two groups of data are equal, and when camera shutter is pressed, the data on hot shoe can change, and cause two
Group data are unequal, and digital comparator generates interrupt request singal, issue interrupt requests to MCU.After MCU responds interrupt requests,
Judgement completes primary flash of light, by four control lines of MCU, connects next group of camera hotshoe, completes to wire back to another completion
The selection of flash lamp, and the flash lamp for just having completed flash of light then enters telegram in reply state, prepares for flash of light next time.The present invention adopts
The hot shoe for connecting camera is recycled with multiple flash lamps, improves flash lamp telegram in reply speed.
The foregoing is merely presently preferred embodiments of the present invention, all equivalent changes done according to scope of the present invention patent with
Modification, is all covered by the present invention.
