Detailed description of the invention

For making the object, technical solutions and advantages of the present invention clearer, below in conjunction with accompanying drawing to this Bright each embodiment is explained in detail.But, it will be understood by those skilled in the art that In each embodiment of the present invention, propose many technology to make reader be more fully understood that the application thin Joint.But, even if there is no these ins and outs and many variations based on following embodiment and amendment, The application each claim technical scheme required for protection can also be realized.

First embodiment of the present invention relates to a kind of information interacting method.Idiographic flow is as shown in Figure 1.

Step 101, the communication module in house pet equipment and the communication mould in the opposite end house pet equipment detected Block sets up communication link.In present embodiment, this house pet equipment is that wearable electronics with house pet sets Standby, such as house pet Intelligent spire lamella, Pet neck ring etc..

Wherein, communication module is bluetooth module, and bluetooth module is the most outwardly sent out broadcast singal, received this The bluetooth of broadcast singal and the Bluetooth pairing sending out broadcast singal, set up communication linkage.Build between communication module Vertical communication link, i.e. establishes the platform of a communication for information between house pet equipment and opposite end house pet equipment.

In the present embodiment, communication linkage is set up by bluetooth module.In actual application, Communication chain can also be set up by the way of near-field communication NFC (Near Field Communication) Connecing, any mode setting up communication linkage all should differ at this within the protection domain of present embodiment One enumerates.

Step 102, mutual card information.I.e. two house pet equipment are by the communication set up in step 101 Link, is exchanged with each other the card information of oneself so that two ends house pet equipment can obtain opposite end The card information of house pet equipment.

Wherein, card information is that user is pre-set by human-computer interaction interface, and is entered by house pet equipment The card information of row storage, including at least name of pet in the card information pre-saved, user contacts Mode, it is also possible to comprise pet age, house pet sex etc. according to demand.

Step 103, it is judged that mutual card information is the need of preservation.If it is determined that mutual business card letter Breath needs to preserve, then perform step 104, preserve mutual card information.Otherwise terminate this stream Journey.By this step, the card information that step 102 obtains can be screened by house pet equipment, in order to stay Under the most useful card information.

Wherein, it is judged that mutual card information the need of preserve according to for one of following condition or its Meaning combination: the signal intensity of the communication module detected, house pet type, communication link set up duration. I.e. according to opposite end house pet and the distance of user's house pet distance, opposite end house pet type and user's house pet type Join degree, the mode such as the length of time that opposite end house pet is played with user house pet, carry out judging whether to hand over The card information obtained mutually preserves.

Specifically, when carrying house pet to take a walk due to user, can be potentially encountered and multiple wear doting on of house pet equipment Thing.If the information of each house pet equipment run into is interacted and preserved, can cause preserving Too much invalid information, as the card information in the house pet equipment that obtains alternately in the case of passing by just is likely to It not the information required for user.Therefore according to the signal intensity of the communication module detected, can get rid of But although other house pet situation not contacting with user house pet, playing close together.Due to inhomogeneity The house pet of type, its life habit is different, therefore using house pet type as judging whether preservation business card The foundation of information, thus help user to find interest to be similar to, the card information of user with a common goal.Separately Outward, set up duration according to communication link, the time that opposite end house pet plays with user house pet can be obtained Length.If communication link to set up duration longer, illustrate that opposite end house pet is preferable with what user house pet played. Therefore, preserve the need of to card information according to above-mentioned conditional judgment, can be automatically to card information Effectively screen, obtain user and be likely more card information interested.

Step 104, house pet equipment will determine that the card information needing to preserve preserves.

Wherein, the card information of preservation is the business card letter of the opposite end house pet obtained alternately by communication link Breath.

By step 101 to step 104, house pet equipment can in the case of need not artificial participation, Automatically obtain useful card information, and preserve.Enable a user to opposite end house pet Owner be inconvenient to reveal contact method or owner the most not house pet at one's side in the case of, obtain opposite end and dote on Thing and the essential information of owner thereof.The card information preserved, user can by house pet equipment or Terminal unit is consulted, thus reaches the purpose helping user to extend social activity.Further, set due to house pet Standby can opposite end pet owner not house pet at one's side in the case of, it is thus achieved that opposite end house pet and its owner's Information.Therefore, when opposite end house pet is in and goes astray from the group state, user can be according to the name obtained in house pet equipment The owner of sheet informational linkage opposite end house pet, it is possible to help others to search out the house pet of loss.

Step 105, business card, according to the pre-conditioned number met in card information, is believed by house pet equipment Breath is sorted out.

Information in the house pet equipment card information to preserving is identified one by one, utilizes in house pet equipment Enumerator pre-conditioned counts what the information in card information met, thus is carried out by card information Classification, meets the pre-conditioned card information of same number, is classified as a class.And according to different classification Meet pre-conditioned number, priority corresponding to classification setting.As, meeting three pre-conditioned is Good friend's class, meet two pre-conditioned for friend's class.The priority meeting three pre-conditioned classifications is high In the priority meeting two pre-conditioned classifications.

Wherein, the condition preset is that user is pre-set by human-computer interaction interface, and is protected by house pet equipment The condition deposited.Comprise communication link in the condition preset sets up duration higher than preset time threshold, detection To the signal intensity of communication module be more than higher than preset signal strength thresholding, the interaction times of card information Pre-determined threshold number of times, house pet type are consistent.

The preset time threshold of communication link, the preset signal strength thresholding of communication module and card information Mutual pre-determined threshold number of times, can be pre-set by human-computer interaction interface for user, and by house pet The information that equipment preserves, or the information in house pet equipment default setting.Growing tall when setting up of communication link Illustrate that the time played between two house pets is longer in preset time threshold；The letter of the communication module detected Number intensity is close higher than the distance between preset signal strength thresholding two house pets of explanation；The friendship of card information The number of times of the chance that number of times is met more than pre-determined threshold number of times two house pets of explanation is more mutually；House pet type one Cause explanation owner to be similar in the hobby kept a pet.

When not classifying due to information preservation, user needs to take a significant amount of time oneself business card interested of searching Information, work efficiency is low.Therefore, by the way of classification and category preferences being set, preserve in display Card information time, the preferential display other card information of high priority class, user is when lookup is browsed, excellent First see oneself most interested card information, it is possible to quickly find interested with user's will with The card information that road closes, has saved user time cost, has improve work efficiency.For different classes of name Sheet information arranges corresponding priority.

Step 106, house pet equipment, by the card information of classification the highest for priority, sends to the end specified End equipment.I.e. house pet equipment is by all of card information in classification the highest for the priority in step 105 All send to the terminal unit specified.

Wherein, the card information in the classification that priority is the highest is satisfied pre-conditioned most business card letter Breath.The terminal unit specified refers to the terminal unit being connected with house pet equipment by wireless communication technology, uses In setting up the information of connecting link with this terminal unit, such as bluetooth title, password etc., can be pre-stored in House pet equipment in.

In the classification that priority is higher, its card information is the highest with the demand matching degree of user.Therefore step In 106, house pet equipment, by most important a part of card information, is sent to terminal unit.Make user Need not browse house pet equipment, directly by checking terminal unit (such as mobile phone, ipad, computer), Can be obtained by card information interested.

In the present embodiment, house pet equipment sets up communication linkage by bluetooth module, obtains opposite end house pet The card information that equipment prestores.The card information got is had a process screened, thus protects Hold the card information being applicable to user's request meeting condition, and the card information preserved is carried out classification row Sequence, during the card information preserved in user checks house pet equipment, the preferential display other name of high priority class Sheet information, by the card information of classification the highest for priority, sends to the terminal unit specified.So, House pet equipment in the case of need not artificial participation, the essential information of automatic interaction pet owner, from And allow users to recognize the valuable card information comprising the other side's essential information quickly and easily, To help user to extend social circle.

Second embodiment of the present invention relates to a kind of information interacting method.Second embodiment is real first Improved on the basis of executing mode, mainly theed improvement is that: in this second embodiment, in advance First store in the step of card information, be set to the attribute of the contact method of user hide attribute.

It is contemplated that in daily life, user's contact method leakage can to user bring unnecessary The situation of harassing and wrecking.Therefore, when comprising the contact method of user in card information, house pet equipment acquiescence will The attribute of user's contact method is set to hide attribute.Utilize the communication link set up, first comprise hidden alternately Hide the card information of user's contact method of attribute.When mutual card information, due to user's contact method Attribute be set to hide attribute so that use the user of opposite end house pet equipment to cannot see that the connection of this user It is mode, thus reaches the purpose that user profile is maintained secrecy.

Owing to its life habit of house pet and the personality of each type are different, therefore raise same type or similar , the situation that interest is identical may be there is in the user of type house pet.Therefore according in the card information received House pet type, it may be judged whether need the contact method of interactive user.Need the contact method of interactive user Time, the attribute changes of the contact method of the user in card information is then display properties by house pet equipment.Profit With the communication link set up, the card information after interaction attributes change.By such mode, alternately During user's contact method, there is a process screened, both reached the purpose of the personal information protecting user, Reach again the original intention helping user to expand social circle.
