Description
Technical field
The present invention relates to a kind of calling talkback method and device, specifically a kind of wired multi-seat paging intercommunication method and device of reader positioning mobile personnel.
Background technology
Hospital is function and the highest place of performance requirement to the call intercom system, below, be representative with hospital environment, the wired acoustic intercom system of building is done the background technology analysis.
In the hospital, the patient is by pressing calling set, and the nurse of call center nurse station, nurse are by the intercommunication paging system main frame of center nurse station, and with patient's intercommunication, this is the pattern of point to the center.Night, ward under nurse on duty, when central station did not have the nurse, the nurse can not be by wired intercom paging system and patient's intercommunication of ward calling in addition, and common wired acoustic intercommunication method can not satisfy patient and medical worker's demand.For remedying mobile calls intercommunication demand, existing scheme is: 1, the nurse can carry radio pager, when the patient calls out, its information is transferred on the beep-pager by system host, its defective is can not intercommunication, and the more additional move of the informational needs of leafing through, and seeing in the subordinate act influences operating efficiency; 2, the nurse also can carry cordless telephone, but there is strict control in China to the power of cordless telephone, " defective " that causes is calling and the intercommunication demand that cordless telephone can not satisfy the patient who particularly crosses over floor far away, and, because the cordless telephone of usefulness on duty is nurses' shared product, the cordless telephone battery maintenance also is a problem of management.Part hospital corridor metal aluminum sheet furred ceiling plays inhibition to the transmission of radio wave, in the inpatient building of many hospitals, even the GMS mobile phone signal of China Mobile all can't normally receive.Because the purchase that battery management difficulty, communication quality do not guarantee, operating efficiency is lower, wireless product useful life is short and higher and the defective of management cost, so, domestic various big hospital, the lesion ratio that is equipped with cordless telephone and radio pager is seldom.Because present wired acoustic intercom system can't realize the intercommunication between a ward intercommunication extension set and the another one ward intercommunication extension set, as medical worker during not in the center nurse station, can cause patient's urgent call can not obtain medical worker's quick response, this is first problem anxious to be solved.
At present, the wired acoustic intercom system of China hospital, be point to single seat intercommunication pattern at center, the seat how much be meant the center nurse station can answer simultaneously and handle call information nurse's number how much.These characteristics cause present calling talkback system, still exist and call out by the intercommunication defective that the line is busy.For example: when patient's intercommunication in nurse of center nurse station and A ward, the patient in B ward calls out the mode of holding the record can only taked, and can not add the new intercommunication of another group in intercommunication, do not accomplish that " 110 call center " is the same together, the intercommunication simultaneously of many seats can be arranged.The patient in B ward has only the patient's who waits for the A ward intercommunication to finish, and could begin intercommunication.In large-scale lesion, the pattern of this single seat intercommunication can cause patient's wait acknowledge overlong time.At present, for the single seat intercommunication of solution paging system causes the defective that the line is busy, remedy way to be: nursing degree is set, calling that the interrupted nursing degree that nursing degree is high is low and intercommunication to notifying from a phone call the intercommunication extension set.But the patient that nursing degree is low has the situation of urgent call certainly, and the high patient of nursing degree, most callings is again a non-emergency call, and that can affirm says, and this compensating mode is a kind of faulty way.So, present wireline call intercom system, anxious second problem to be solved is expansion center nurse station list seat intercommunication pattern, and the patient need not waited for.
When public health event took place, the patient who pours in can cause the seriously in short supply of existing nursing staff, and the corridor total length of lesion is about 50 meters usually, and during accident, it is fleabites that the medical worker seeks other medical workers.Existing solution is, by broadcasting, verbal announcement sent out in all rooms at central station, seeks particular medical person.But for the patient, it is crucial resting, and during sleep, the information that is broadcasted is frequently bothered, and can cause adverse consequences.How the medical worker directly searches out other medical workers and carries out effective intercommunication, and this is present wireline call intercom system, the 3rd problem anxious to be solved.
Since the needs of management, a nurse, the patient of the several appointment berths of meeting intensive care.Present calling system can't be distinguished patient's charge nurse, and this is that this is present wireline call intercom system, the 4th problem anxious to be solved.

Embodiment
Embodiment one
The wired multi-seat paging intercommunication method of reader positioning mobile personnel, flow process is specifically carried out as shown in Figure 4 according to the following steps:
Track and localization, data are preserved: the reader of system by road junction or doorway (keyboard operation identification or/and living things feature recognition or/and radio-frequency (RF) identification), discern respondent (nurse and doctor's) path actively or passively, reader/high-rise host record respondent (nurse and doctor) by or rest near each position reader time.Respondent (nurse and doctor) can be used in the mode of input information on the keyboard of reader, informs that reader arrives; The respondent also can inform that reader arrives by the mode of living things feature recognitions such as fingerprint recognition; The respondent also can carry the RFID electronic tag, and reader obtains arrival information by radio-frequency (RF) identification.Reader is built up in doorway or road junction, when reader knows that the respondent arrives, promptly finishes refreshing of track and localization.The time of advent/duration can be by reader/high-rise host record.As when not having other readers that new arrival record is arranged, the zone of this reader (room) for this respondent position, finishes the location.When there was not record in reader, respondent's position was defaulted as high-rise main frame position or other predefined alternative sites.
The user calls out the automatically relevant removable personnel positions of inquiry of back: as user (patient) when demand is arranged, after intercommunication extension set or the calling of high-rise main frame, system is by program (can table look-up or look into database), learn user's appointment respondent's (predefined charge nurse or predefined other medical workers) code, judge its position by road junction or doorway reader data.The respondent can be 1 people, can be many people.Respondent's position can be moved, also can zone of first fixed directional, and as doctor's office, nurse station.If the sensing fixed area, when not having the respondent in the zone, system can inform the caller or directly be transferred to respondent's reposition by acousto-optic.
After establishing destination address, by setting call by pattern queuing and intercommunication: respondent (charge nurse) is if in central station (nurse station), high-rise main frame ring or automatic speech notice, high-rise main frame screen can directly show the name or the code of specifying respondent's name or code and caller, but the intercommunication of respondent's off-hook, if any setting in advance, also can direct hands-free intercommunication, needn't carry out any off-hook generic operation, be used for quick response.If this moment, high-rise main frame is being handled nurse and another patient's intercommunication, and simultaneously, also have other relevant nurses near the high-rise main frame, carry out near this new call information will drop on the call intercommunication extension set, perhaps, drop on the other high-rise main frame and carry out.If do not have another respondent this moment near the high-rise main frame, the respondent then seeks in other zones in system.If all do not find another respondent in whole zone, high-rise main frame can have been pointed out new incoming call, and when previous intercommunication finishes, begins new intercommunication again.If this respondent (charge nurse) is in the ward or other rooms, system sends ring or/and screen light shows (at night by near the call of the intercommunication respondent extension set, can be only show with the light of controllable brightness) or/and automatic speech is informed respondent (charge nurse), tell it that user (patient) calling is arranged.This moment, respondent (charge nurse) can be directly and user's intercommunication, also can set up telecommunications full duplex intercommunication path by the intercommunication extension set button in this room of flicking.
In the intercommunication process, other respondents can transfer intercommunication: in the intercommunication process, intercommunication need be transferred to other people as respondent (charge nurse), can be directly by the keyboard of intercommunication extension set, and the input object code carries out the target switching.After the switching, the user can with new respondent (attending doctor) intercommunication.
Calling talkback finishes and data are preserved: the side's on-hook among the both sides of intercommunication or press clear key, terminated call intercommunication process.Data are preserved: the data such as concluding time of respondent's position time, user's call time, intercommunication content and time, calling/intercommunication, and by high-rise host record, for management level provide the behavior foundation.
The calling talkback flow process: after user (patient) used the intercommunication call extension, the intercommunication extension set mail to high-rise main frame with the request msg sign indicating number.Table look-up by high-rise main frame, learn user's respondent's (charge nurse) code, search by reader, user's respondent (charge nurse) is if in central station (nurse station), high-rise main frame ring, the request intercommunication, if this respondent (charge nurse) is in the ward or other rooms, learn its position by the reader on doorway, high-rise main frame informs that by machine talk respondent (charge nurse) has user (patient) to call out, respondent (charge nurse) sets up intercommunication and connects by confirming intercommunication by the intercommunication extension set in this room, carries out intercommunication.
The use reader location technology of present embodiment is carried out the paging system of calling talkback, and it comprises: one or more readers, notify from a phone call intercommunication extension set, one or more high-rise main frames more than two.Reader reads the position with room, related personnel place, submits to high-rise main frame or call intercommunication extension set.When the calling personnel call out the related personnel, notify from a phone call the position of intercommunication extension set according to the related personnel, set up full duplex telecommunications and connect, converse.
The structure of the reader of employing radio-frequency (RF) identification comprises that the long line of controller, radio frequency module for reading and writing and digital signal drives and input buffer circuit as shown in Figure 1.Reader possesses the feature of people, thing being distinguished identification, and it can be distinguished people, thing.Reader of the present invention, can be one or more combinations of following multiple reader: 1, optical picture identifies other reader, and it can discern nurse cap, nurse's clothes at a distance; 2, recognition of face reader, it can discern personnel at a distance, as doctor or nurse; 3, fingerprint recognition reader, its contact identification personnel; 4, palmmprint palm shape reader, it can discern the personnel that are in contact with it; 5 speech recognition readers; 6.RFID discerns reader, and the RFID reader can possess literacy; 7 keyboard readers can be known the people who arrives reader according to the password of keyboard input.
RFID identification reader will use transponder, and transponder is a movable part, is carried by personnel.It can pass through REID, allows reader discern.Transponder is an electronic tag, and it can be made into the form of radio-frequency card.Whether needs add packed battery according to transponder, transponder can be divided into three types of passive (passive type), half passive (semi-passive) and active (active) transponders.
Passive balise can be divided into electromagnetic wave resonance identification label according to data type and have the electronic tag of IC chip.The not subsidiary battery of passive balise, outside the reading range of reader, transponder is in passive states; Within the reading range of reader, transponder is the needed electric energy of extraction work from the radio-frequency (RF) energy that reader sends.
In half passive balise battery is housed, but battery only helps out, it does auxiliary the support to the circuit supply of keeping data or to the required voltage of transponder chip operation.Transponder circuit power consumption itself seldom is in resting state at ordinary times.When transponder enters the reading range of reader, be subjected to the excitation of the radio-frequency (RF) energy that reader sends and enter operating state, it is the same with passive balise, and the radio-frequency (RF) energy that is used for transport communication is derived from reader.
The working power of active balise is supplied with by internal cell fully, and the internal cell energy also partly is converted to transponder and reader communication energy needed simultaneously.
The RFID reader is fixed installation, connects the intercommunication paging system.It possesses following function: 1, with RF-wise to the transponder transmission of power; 2, sense data or write data from transponder to transponder; 3, finish the information processing of reading of data and realize application operating; 4, if needed, energy and high-rise main frame or call intercommunication extension set interactive information.
The RFID reader also can have other another names, as read write line, requestor, communicator, scanner.Reader has 3 elementary cells: control unit, baseband processing unit, RF processing unit.Wherein, control unit has software interface agreement and embedded hardware, and baseband processing unit has base band and amplifies and the base band adjusting module the preposition amplification of RF processing unit, vibration/mixing, modulating/demodulating, transmission/receiver module.RF processing unit and baseband processing unit intercommunication input/output signal, baseband processing unit and control unit intercommunication input/output signal.The control unit of reader is connected to high-rise main frame by cable.
The antenna circuit of RFID reader and radio frequency module for reading and writing form the keyboard reader with after being changed to keyboard; The antenna circuit of RFID reader and radio frequency module for reading and writing can become the bio-identification reader with being changed to biometric sensor and increasing the bio-identification algorithm in director demon.
The speech recognition reader can rely on password and use, and for each authorized person, the password of oneself can be arranged all, and reader has the password storehouse, also can use password storehouse in the high-rise main frame by communication.For each authorized person, we can say own distinctive password.Reader comprises the tongue of a series of sound vector description by the signal of telecommunication dynamic change of microphone, calculates the gap of process person and sound bank donor tongue then, judges near the speaker's of reader identity.The speech recognition reader does not need the people directly to contact with equipment.
The recognition of face reader does not need the people directly to contact with equipment yet.It forms identification parameter to the position relation of the facial characteristics of eyebrow, eyes, nose and mouth by camera motion capture people's face, simultaneously, personnel people from storehouse face of people's face that captures and typing is in advance compared identification, judges people's identity.Face recognition technology is primarily aimed at the part that face is not easy to change and carries out image processing, comprising the peripheral region of eye profile, cheekbone and the fringe region of mouth etc.
Optical picture identifies other reader, and it can discern nurse cap, nurse's clothes, epaulet at a distance, and its job step is identical with people's face reader, and just recognizer is simple than people's face reader.
The grain pattern of fingerprint recognition reader identification finger skin, the feature in the breakpoint of lines, crosspoint in the pattern Processing, the uniqueness of dependence feature is mapped a people and his fingerprint, by fingerprint characteristic that compares him and the fingerprint characteristic of preserving in advance, identifier's true identity.Fingerprint recognition relates to processes such as the comparison of fingerprint image acquisition, fingerprint image processing, feature extraction, preservation data, characteristic value and coupling.The image of the somatic fingerprint that reads by the fingerprint fetch equipment at first, and the original fingerprint image carried out preliminary processing, make it more clear.Then, algorithm for recognizing fingerprint is set up the numeral of fingerprint---characteristic, and this is a kind of unidirectional conversion, can convert characteristic to from fingerprint, but can not be converted into fingerprint from characteristic, two pieces of different fingerprints can not produce identical characteristic." minutiae point " data point (Minutiae) that the tag file storage is found from fingerprint image, the just bifurcation of those fingerprint lines or tip point.Minutiae point and directional information combination, show the position relation of each node by algorithm, the data of generation are called template, save as the record about big or small 1KB.At last,, the template of two fingerprints is compared, calculate their similarity degree, finally obtain the matching result of two fingerprints by fuzzy method relatively.
The palmmprint palm used technology of shape reader and method and fingerprint are similar.The advantage of palm shape identification is that comparison speed is fast, can not the typing rate very low.
Reader structurally can be done with call intercommunication extension set and be in the same place, and becomes the call intercommunication extension set of band reader.
The structure of intercommunication extension set as shown in Figure 2, notify from a phone call the intercommunication extension set button is arranged, microphone, loud speaker, possesses the intercommunication ability, the Code And Decode ability, notify from a phone call the intercommunication extension set device address is arranged, and can be according to caller's requirement, can directly send the call recipient device address, also can send destination address, destination address sends to associated terminal by broadcast mode, each terminal reads distinguishing mark according to each reader, choosing blip the last time the position occurs or by blip motion mode measuring and calculating, the address of equipment is notified from a phone call in the intercommunication of determining, carries out the intercommunication activity at reader.
High-rise main frame provides management service, and by processing, analysis and the excavation to data, for correct decisions provides foundation, high-rise main frame also possesses the intercommunication of call extension function.
For realizing the integrated service requirement of Ground Connection in Intelligent Building, procotol is used in system digits communication, and this channel provides Qos to guarantee.The English full name of QoS is " Quality of Service ", Chinese " service quality " by name.QoS is a kind of security mechanism of network, is with a kind of technology that solves problems such as network delay and obstruction.When network over loading or when congested, QoS can guarantee that the important service amount is not postponed or abandons, and guarantees the efficient operation of network simultaneously.Network has classification feature, and which kind of the grid of QoS can be discerned and use which kind of packet of generation.For example: in the hospital, a lesion has 128 berths, each berth all carries out the intravenous injection treatment, each berth per second has 1 drops physic liquor drippage, the time data of each this drippage of berth will be delivered to high-rise main frame, system's extension set per second will produce 128 packets, arrives high-rise main frame by agreement.These data can not abandon.This will classify.Network has marking Function, after the recognition data bag, mark it, and other network equipments could be discerned this data easily like this.Because classification may be complicated, therefore preferably only carries out once.Just must carry out mark after identification is used and handle, can carry out processed to this application so that guarantee network to its packet.Network has the processed function, and network can be distinguished the download of uploading of data message in real time information and the building, does not interrupt real time information when processed just can guarantee to carry out large-scale download.Network is set priority by flow agreement (SLA, Service Level Agreement service-level agreement) to data flow, on the networks/protocols aspect, according to the yardstick of deciding through consultation mutually, is set with the boundaries such as performance, throughput, delay of guarantee with this.The network data flow of some particular forms need define service quality.For example: the transfusion speed of each berth; The call state of each extension set; Equipment alarm information.
For realizing the network security requirement of Ground Connection in Intelligent Building, each equipment that is connected to network also can have a dynamic address except that having fixing physical address, and system can directly carry out transfer of data by dynamic address, and dynamic address is resolved by high-rise main frame.Use for example: when the leader was in building, its all information all were reluctant to be known by the external world.Communication system of the present invention has the dynamic address function, adapts to the defendance privacy requirements.
