Embodiment
Embodying the exemplary embodiment of feature of present invention and advantage will describe in detail in the following description.Should
What is understood is that the present invention can have various changes in different embodiments, and it does not all depart from this hair
Bright scope, and explanation therein and diagram are treated as purposes of discussion in itself, and it is not used to limitation originally
Invention.
It is well known that infrared ray be wavelength in 750nm to the electromagnetic wave between 1mm, its frequency is higher than
Microwave and less than visible ray, be the light that a kind of human eye be can't see.Because ultrared wavelength is relatively short,
It is poor to the diffracting power of barrier, so being generally used for the one-to-one matching of short-distance wireless communication
In scene.
In existing custodial care facility, for example, plug-in type monitor, infrared communication technique is as a kind of normal
Communication mode is widely used in the infrared communication between custodial care facility and card module, and this kind leads to
Letter mode plug and play, it is ensured that higher stability, and manufacturing cost is relatively low.
However, because the model of card module is different so that the communication that its mode of operation supported is allowed
Speed is not quite similar, and the custodial care facility of single hardware configuration is difficult the different card module of compatible communication speed.
Based on this, compatible for custodial care facility and different card modules, spy proposes a kind of infrared
Communication means.
Referring to Fig. 2, in one embodiment, a kind of infrared communication method comprises the following steps：
Step 210, whether custodial care facility detection card module connects.
Custodial care facility is set up before infrared communication with card module, and custodial care facility needs the company to card module
The state of connecing is detected, and then is confirmed whether to need to enter mode of operation, sets up custodial care facility and plug-in unit mould
The infrared communication of block.
For example, custodial care facility is electrically connected with card module by infrared interface, card module will pass through this
Infrared interface sends connection enabling signal to custodial care facility, and custodial care facility is judged by the connection enabling signal
Card module is connected thereto.
Further, if card module is connected, into step 220, conversely, custodial care facility continues
Constantly the connection status to card module is detected, until detecting in card module connection, is entered
Step 220.
Step 220, custodial care facility is powered to card module, and starts infrared lead to according to present communications speed
Letter.
In the present embodiment, on card module after electricity, the mode of operation that card module will be supported according to it
The maximum communication rate allowed enters mode of operation, and wait sets up infrared communication with custodial care facility.
Table 1
| Numbering | The mode of operation of card module | Traffic rate |
| 1 | FIR mode | Maximum communication rate |
| 2 | FIR mode | Traffic rate after maximum communication rate, reduction of speed |
| 3 | MIR patterns | Maximum communication rate |
| 4 | MIR patterns | Traffic rate after maximum communication rate, reduction of speed |
| 5 | SIR patterns | Maximum communication rate |
As shown in table 1, the mode of operation that card module is supported includes FIR mode, MIR patterns, SIR
The traffic rate allowed under pattern, each mode of operation then includes the communication after maximum communication rate and reduction of speed
Speed.Wherein, maximum communication rate is shaken hands to card module with custodial care facility, logical after reduction of speed
Believe that speed can be then used under card module ideal case, or, after plug-in module execution is stable.
Matched in order to the traffic rate with card module, it is current during custodial care facility startup infrared communication
Traffic rate can be any one in the inner all traffic rates of table 1.The current traffic rate can be
What the mode of operation that the card module that is connected by custodial care facility according to it is supported was pre-set, can also be by
Custodial care facility is randomly choosed when starting infrared communication.For example, the mode of operation of card module is FIR moulds
Formula, then custodial care facility detect card module connection after, present communications speed is preset as FIR moulds first
The maximum communication rate that formula is allowed.
Step 230, shaken hands according to present communications speed and card module.
So-called shake hands refers to that custodial care facility sends handshake request according to present communications speed to card module,
If the current traffic rate is matched with the maximum communication rate that the mode of operation that card module is supported is allowed,
Then card module carries out response, that is, success of shaking hands, so as to set up custodial care facility and plug-in unit to the handshake request
Infrared communication between module.
Specifically, step 231, judge to shake hands in preset time and whether succeed.
Preset time can be pre-set according to the maximum tolerance degree of user, for example, preset time is
5 minutes, then the transmission time of each handshake request is to be spaced 5 minutes.
If shaking hands success in preset time, into step 232, set up custodial care facility and card module it
Between infrared communication.
If conversely, it is unsuccessful to be shaken hands in preset time, into step 233, supporting custodial care facility
The first traffic rate that mode of operation is allowed is polled, using the first traffic rate for being polled to as working as
Preceding traffic rate, and return to step 230, proceed to shake hands with card module, until card module pair
Handshake request has carried out response.
In the present embodiment, the mode of operation that custodial care facility is supported is all working mould that card module is supported
Formula, it includes FIR mode, MIR patterns, SIR patterns, and the first traffic rate is then these pattern institutes
Whole traffic rates of permission, including card module support mode of operation allowed maximum communication rate,
Traffic rate after reduction of speed etc., the success rate that custodial care facility is shaken hands from different card modules is improved with this.
By process as described above, custodial care facility the mode of operation supported it is allowed first
Traffic rate carries out searching loop, is attempted by way of automatic adjusument present communications speed and communication speed
The successful handshake of the different card module of rate, custodial care facility and different card modules are realized with this
It is compatible.
Further, since only by communication protocol type or traffic rate card module not easy to identify, for example,
The high speed card module of FIR mode and the high speed card module of SIR patterns all use IRDA agreements, or
The maximum communication speed phase of person, the high speed card module of SIR patterns and the low speed card module of MIR patterns
Closely, and by custodial care facility the poll of the whole traffic rates allowed all working pattern, it is to avoid
Card module it is not easy to identify and can not be compatible the problem of, infrared data is done while clutter can also be reduced
Disturb, so as to improve the antijamming capability of infrared communication.
Referring to Fig. 3, in one embodiment, after step 232, method as described above also include with
Lower step：
Step 310, speed governing inquiry request is sent to card module, to obtain card module according to storage
Version information inquires the response for asking to carry out to speed governing.
Version information includes the second traffic rate that the mode of operation of card module support is allowed.The work
Pattern can be any one in FIR mode, MIR patterns or SIR patterns, correspondingly, second
Traffic rate can then include maximum communication rate, the traffic rate after reduction of speed that mode of operation be allowed,
The maximum communication rate that mode of operation is allowed can also only be included.
If it is appreciated that the second communication speed in version information is included after maximum communication rate and reduction of speed
Traffic rate, then being loaded with the card module of the corresponding version of the version information allows reduction of speed, i.e. plug-in unit mould
Block is set up after infrared communication with custodial care facility, can be logical from maximum by the present communications speed of card module
Believe the traffic rate after rate adaptation to reduction of speed, accordingly, the present communications speed of custodial care facility is also required to
It is adjusted in synchronism to the traffic rate after reduction of speed, to ensure that the traffic rate after the two reduction of speed remains able to matching.
Based on this, custodial care facility is set up after infrared communication with card module, and card module will receive prison
The speed governing inquiry request that equipment is sent is protected, if card module learns that it allows drop according to the version information of storage
Speed, then carry out response to speed governing inquiry request.Sent out for example, answering is card module to custodial care facility
Response message is sent, the response message is generated by the traffic rate after reduction of speed.
If conversely, card module does not allow reduction of speed, speed governing inquiry request can not be replied.
Step 330, present communications speed is adjusted according to the second traffic rate carried in response,
To carry out infrared communication according to the present communications speed of regulation and card module.
As described above, the second traffic rate carried in response is the traffic rate after card module reduction of speed,
In order to ensure custodial care facility and card module after reduction of speed can traffic rate match, custodial care facility is got
Traffic rate after the reduction of speed, will adjust the traffic rate after present communications speed to the reduction of speed of itself.
Allowed it should be noted that the traffic rate after reduction of speed is the mode of operation that custodial care facility is supported
One kind in first traffic rate.That is, custodial care facility is also to allow reduction of speed.
By process as described above, custodial care facility is set up after infrared communication with card module, if plug-in unit
Module allows reduction of speed, and custodial care facility also will adaptively be dropped by sending speed governing inquiry request to its own
Speed, so that ensure to continue therebetween to carry out infrared communication with the traffic rate after reduction of speed, it is further real
The compatible of card module and custodial care facility is showed.
In addition, when card module is standby, interacting for a large amount of infrared datas can't be carried out with custodial care facility,
And only need to interact a small amount of channel holding instruction, to keep what is set up between card module and custodial care facility
Infrared communication, by reduction of speed while card module and custodial care facility, not only reduces the two operation required
Power consumption, improve the service life of the two, and ensure that the security of data interaction, improve number
According to interactive stability.
In one embodiment, method as described above is further comprising the steps of：
It is current logical when successfully to shake hands if obtaining the response for inquiring request to speed governing less than card module
Believe that speed keeps infrared communication with card module.
If as described above, card module does not allow reduction of speed, response can not be carried out to speed governing inquiry request,
Now, card module continues maximum communication rate and the custodial care facility allowed with the mode of operation of its support
Carry out infrared communication.
When being shaken hands successfully due to custodial care facility and card module, the present communications speed of custodial care facility is slotting
The maximum communication rate that the mode of operation that part module is supported is allowed, so, if card module does not allow drop
Speed, then custodial care facility will remain at the present communications speed shaken hands when successfully and card module progress is red
Outer communication, ensures that traffic rate therebetween is matched with this.
Referring to Fig. 4, in one embodiment, step 330 comprises the following steps：
Step 331, serial port baud rate is adjusted to preset value according to the second traffic rate carried in response,
Preset value matches with second traffic rate.
The second traffic rate carried in response is the traffic rate after card module reduction of speed, and preset value is with being somebody's turn to do
Traffic rate matching after reduction of speed, then adjust the communication corresponded to the serial port baud rate of preset value after reduction of speed
Speed.That is, in speed regulation process, serial port baud rate is with the second traffic rate carried in response
Change and change.
Step 333, signal is reconfigured according to the output of the serial port baud rate of regulation, entered by reconfiguring signal
Traffic rate is reconfigured before the trade.
In the present embodiment, it is to connect custodial care facility and card module that present communications speed, which is reconfigured,
Infrared interface resetted.
When custodial care facility according to the serial port baud rate of regulation knows that serial port baud rate is changed, it will export
Signal is reconfigured, the infrared interface is resetted by reconfiguring signal so that infrared after reset connects
Traffic rate after the reduction of speed that mouth can be matched according to the serial port baud rate with regulation carries out the receipts of infrared data
Hair, that is, the present communications speed reconfigured is the traffic rate after reduction of speed.
Step 335, according to the serial port baud rate output control selection signal of regulation, with according to control selections
Signal output infrared data corresponding with the second traffic rate, and then by infrared data according to working as reconfiguring
Preceding traffic rate is sent to card module.
As described above, custodial care facility will set up infrared communication except needing traffic rate to match with card module,
Also need to the two and be in identical mode of operation, therefore, after present communications speed is reconfigured, monitoring
Equipment can enter and regulation also by the serial port baud rate output control selection signal according to regulation
The corresponding mode of operation of traffic rate after the reduction of speed of serial port baud rate matching, with defeated in the mode of operation
Go out corresponding infrared data, so as to ensure after reduction of speed, custodial care facility can be with identical work with card module
Operation mode and the traffic rate of matching keep infrared communication.
Similarly, the down speeding procedure of card module and the down speeding procedure of custodial care facility are consistent, herein no longer one by one
Repeat.
