Description

Novel Internet Medical service platform

A lot of people went to a hospital to see a doctor such experiment and feeling, not only register difficulty, queue up tired, and with great difficulty see doctor, " Long March " is just calculated and is really started---and every inspection, each treatment are run under wanting upstairs house and are gone for some times to have a prescription priced, pay dues, by medicine, count the part that the time really exchanged with doctor only accounts for the process of seeing a doctor.Namely patient to outpatient service → queue up → register → wait to see the doctor → go to a doctor → have a prescription priced → payment → wait examine → check → go to a doctor → have a prescription priced again again → pay the fees again → get it filled → treat → from institute.

There is many drawbacks in this pattern, because each link needs to queue up.Outstanding problem shows following several respects.(1), outpatient clinic ubiquity " three length one are short " phenomenon, under natural process mode, defines 3 " peaks " of Outpatient Service Flow, namely registers, goes to a doctor, checks peak

(2), the loaded down with trivial details patient of checking process medical after, doctor has opened several checklist to him, and the inspection wherein had needs reservation, the special preparation such as long-pending urine on an empty stomach before some inspections then require to check.

(3), Clinical service guiding shortcoming output checklist after, about have the patient of half to propose: " where doing inspection? " and so on problem, there is no lucid road sign or Clinical service guiding.

(4), there is the natively uncomfortable patient of hidden danger and waste the much time in invalid wait in doctor-patient relationship, and the discomfort of health adds the agitation of spirit, causes conflict between doctors and patients to be triggered at any moment.In addition, do not seek advice from detail before medical, some patients want all to do again from the beginning because registering or owing to not preparing by some special examined requirement (as on an empty stomach, clean enteron aisle etc.), so that can not check and need select a time heavily to come the same day; Some sees the patient of training, and essential factor is registered, have a prescription priced, pay dues, get it filled, treat and run back and forth; Some is unclear or lack medicine because of pharmacy because doctor hands over, or because of skin test, patient wants repeat runs is run down; Some is clipped in section office doorway because of audit report, must be asked for, cause report to be got by mistake, tear to pieces so that lose, buried the hidden danger of conflict between doctors and patients by patient.Moreover when peak appears in Outpatient Service Flow, the mood of medical worker also can become irritated because patient, do not occur unavoidably dealing with phenomenon, makes service quality be difficult to ensure.Thus add the grievance of patient, bury the hidden danger of Doctor-patient conflicts.

Improve the countermeasure of existing Outpatient Service Flow

Reproducing Outpatient Service Flow is patient-centered health care, on the basis of transition of people's conceptions, operation changing strategy, utilize infotech, introducing business process reengineering is theoretical, existing procedure " bottleneck " problem is reintegrated, changes service mode, shorten the waiting time of patient, improve the consultation rate in the hospital unit time, to obtain good economic benefit and social benefit.

Infotech infotech is that Outpatient Service Flow restructuring provides necessary instrument and means.In Practices of Outpatient Reengineering process, infotech plays very important effect.Do not have the support of infotech, the enforcement of Outpatient Service Flow restructuring is very difficult.Expert system of being unified by agrment information system and thought thereof are applied in Workflow restructuring, make the rule that people have the ability to break traditions, and create the working method made new advances, are conducive to the reasonable implementation of Workflow restructuring scheme.

To wait to see the doctor, the realizations such as place, doctor's clinic, marking prices and payment Pharmacy, Medical Laboratory are information-based to be connected, and so the raising of information transmission speed can be raised the efficiency widely.The information system management majority of medical institutions at different levels adopts computing machine to carry out connection management, but its cost is high, radiation is large, resource utilization is little, invents a kind of electronic equipment being exclusively used in hospital information thus and solves.

(1), adopt the control of touch-screen, button realization to equipment, meet the control under different modes.

(2), there is speech talkback function, the communication of all departments of hospital can be realized easily.

(3), information carries out wireless biography and sends, and convert information can become voice messaging to carry out handled easily (example: pharmacy place can get it filled according to voice messaging) by receiving end.

(4), can carry out with PC being connected (example: external printer carries out data-printing).

Realize the informationization to whole class hour by the function such as above-mentioned, set up the information service platform that a personal-machine is mutual.

Although be a scheme of the invention, exploitativeness is most important, the main line therefore carrying out inventing with a chip connects.

After hospitalier enters hospital, first carry out electronics to register (the true knowledge identity of hospitalier, numbering, section office distribution section, points for attention, and numbering is sent to each section office), after hospitalier takes numbering, go to a doctor, carry out checking, treat (use Integrate make appropriate arrangements the situation of seeking medical advice) after diagnosing for this reason, finally carry out having a prescription priced, paying the fees get it filled (cash charging can be established, stamp the card and collect).

Need to carry out control treatment, data processing and signal transacting according to control system, 16 single-chip microcomputers of Ling Yang are for adapting to this development invention, and its CPU core adopts the up-to-date release of Ling Yang (MicrocontrollerandSignalProcessor) microprocessor of 16 bit chip, has DSP function and has very strong information processing capability.16 that are formed by it series monolithic adopt be the fast formula integrated morphology of mould, it with rOM, RAM of integrated different scales and the various Peripheral Interface parts of feature richness centered by kernel, SPCE061A continues the controller having a 16 bit architectures that after series of products SPCE500A etc., Ling Yang science and technology is released.With SPCE500A unlike consider in memory resource user less resource demand and be convenient to the functions such as program debug, the flash memory (FLASH) of embedded 32K in SPCE061A.Higher processing speed makes complicated digital signal can be processed easily, rapidly.Therefore, with sPCE061A microcontroller for core be applicable to digital signal processing, the one of speech recognition application field product most economically selects, and makes this chip have higher function and lower cost.

Three, each module invention of system and theoretical analysis

According to the theoretical analysis to system, whole system is primarily of compositions such as SPCE061A, speech talkback, the display of section picture, data transmission, power management, exterior storage.System can realize the function such as speech talkback, text voice output, data-printing (guide), external memory storage, multipath control, completes control to system and operation by touch-screen, keyboard.

The principle of work of touch-screen and LCD display

When peak appears in Outpatient Service Flow, the mood of medical worker also can become irritated because patient, do not occur unavoidably dealing with phenomenon, makes service quality be difficult to ensure.Thus add the grievance of patient, buried the hidden danger of Doctor-patient conflicts, for increasing the work efficiency of medical worker, Integrate adopts touch-screen to control, move finger and just the basic condition of hospitalier can be sent to each section office, touch screen operation, invention as follows:

In order to operational convenience, touch-screen is adopted to realize controlling.During work, first touch with finger or other object the touch-screen being arranged on display front end, then system carrys out the input of regioselective information according to the segment mark of finger touch or menu position.Touch-screen is by touching detection part and touch screen controller forms; Touching detection part is arranged on before indicator screen, for detecting user touch location, send touch screen controller after acceptance; And the Main Function of touch screen controller receives touch information from touch point detection device, and convert it to contact coordinate, then give CPU, it can receive order that CPU sends simultaneously and be performed.Infrared touch panel utilizes the infrared ray matrix that X, Y-direction are gathered to detect and the touch of consumer positioning.Infrared touch panel installs a circuit board housing before display, and circuit board is at screen four limit arrangement infrared transmitting tube and infrared receiving tube, and one_to_one corresponding forms the infrared ray matrix anyhow intersected.User, when touch screen, points two infrared rays anyhow that will block through this position, thus can judge the position of touch point at screen.Any touching object all can change the infrared ray on contact and realize touch screen operation.Infrared touch panel is not by electric current, voltage and electrostatic interference, and suitable rugged environment condition, can meet the demand of this controller.The resolution of up-to-date technology the 5th generation infrared screen depends on infrared tube number, sweep frequency and difference arithmetic, resolution reaches 1000X720, as for saying that infrared screen is unstable under illumination condition, from second generation infrared touch panel, just overcome this weakness of anti-light interference preferably.5th generation infrared touch panel be the intellectual technology product of all new generation, it achieve 1000*720 high resolving power, multi-level self-regulation and self-healing hardware adaptive faculty and highly intelligentized differentiation identification, can use arbitrarily under various rugged surroundings for a long time.And can for customization extended function, as network control, phonoreception should, human body proximity induction, user software encipherment protection, infrared data transmission etc.Originally the infrared touch panel another one major defect of media and communications is that knock rating is poor, infrared screen can select any client to think satisfied Anti-explosive glass and can not increase too many cost and affect usability completely in fact, and this is that other touch-screen cannot imitate.

LQ057Q3DC02 is 5.7 inch of 320 × 240 colored TFTLCD of SHARP company.Each pixel is made up of R, G, B sub-pixel, and each sub-pixel has 6 gray scales, and namely each pixel has 18 looks, can reach the true color effect of 262144 kinds of colors.Adopt cathode-ray tube (CRT) (CCFT) transmission-type backlight, brightness is up to 50Cd/m2: the response time, lower than 30ms, can realize without smear display dynamic segment picture: adopt digital interface data bus, be convenient to drived control.

One piece of LCDs is driven to need 2 kinds of drivers: data driver and line scanning driver.Data driver is responsible for the reception of 3 look data-signals, sampling and maintenance, through the output actual drive signal of D/A conversion; Sweep signal driver produces progressive-scan signal, thus realizes the addressing to LCD display pixel.Control TFT-LCD driver needs 4 kinds of signals: data shifts clock (CLK), row synchronous clock (Hsync), frame synchronization clock (Vsync) and data-signal (DATE).Section passes through 18 bit parallel data buses (RO ~ R5, GO ~ G5, B0 ~ B5) as data under the effect of clock sync signal.Write data sampling retainer, is converted into the TFT stored in each pixel after grey scale signal, makes it normally show,

The contact of doctor is needed between each section office, normally utilize the reception and registration of phone or nurse, by the restriction of network or personnel, can not this communication issue of solution of system, therefore realize connecting with speech talkback, because this platform realizes communication by Integrate net, therefore can connect fast, the situation of each section office can be learnt, then can inform hospitalier, the pressure of part section office can be alleviated, carry out dividing potential drop solution (1), (2).

The A/D converter of SPCE061A has 8 passages, and wherein have a passage to be MIC-IN input, it is specifically designed to samples to voice signal.Voice signal converts electric signal to through MIC, by capacitance every falling flip-flop, then inputs to the inner prime amplifier of SPCE061A.SPCE061A internal Auto Gain control circuit AGC can follow the tracks of at any time, monitor the audio signal level that prime amplifier exports, and when input signal increases, agc circuit reduces the gain of amplifier automatically; When input signal reduces, agc circuit increases the gain of amplifier automatically, and the signal entering A/D can be made to remain on optimizing level, can reduce to minimum by slicing again.The sound signal of A/D converter to input carries out 8KHz sampling, and encodes according to Ling Yang audio coding formats, per secondly will take the storage space of 16kBits.It is that the SRAM memory HM628128A of 1Mbits carrys out voice data that system also expands one piece of capacity.

Wireless calling management system is sent by data, data receiver two parts form, and is applied to the Public places such as hospital, hotel, hotel.Data send (calling part) can by managerial personnel's sets itself coded address, and each transmitter has the unique address of codified.

Repeatedly travel to and fro between all departments in patient assessment's process, queuing repeatedly, to wait, a large amount of time energy is consumed in non-diagnosis and treatment process.Outpatient Service Flow pattern existing defects is that patient complains inconvenient main cause of seeking medical advice.Data receiver part can be arranged on constituent parts, data receiver to after decode, show the information of patient on a display screen, as carried out Collective stewardship, reduce error, patient wait time, increase efficiency.Make the suggestion of patient can feed back to administration and supervision authorities timely, modify and increase the quality of serving.

Communication data adopts pulse code, and so-called pulse code, represents the pulse of the bits per inch number of it is believed that exactly.The coding of example program is with pulsewidth 561us, cycle 4*561us representative " 1 ": with pulsewidth 561us, cycle 2*561us representative " 0 ".It is 1/3 that pulse signal is all modulated at dutycycle, frequency be 38KHz carrier wave on send again, the signal " 1 " after modulation and " 0 " have 2 benefits like this:

(1), decrease effective launch time, be conducive to reducing average power consumption, very important for adopting the circuit of rechargeable battery like this.

(2), external interference signals mostly is tempolabile signal, is conducive to anti-interference.

Get it filled for making hospitalier and save time, therefore medicine to be prepared in advance, the simplest method is after ending medicine, medicine name is directly sent to pharmacy display, doctor gets it filled according to prompting, 3 links of having a prescription priced, pay dues, get it filled can be integrated, 3 windows merge, and reduce the time of patient's waste on queuing up.

Because SPCE061A has powerful data-handling capacity, maximum clock frequency can reach 49MHz, possesses the advantage that arithmetic speed is high, SPCE061A has a road to be exclusively used in the A/D change-over circuit (MIC input) of speech signal collection, the voice signal that can be used for carrying out speech recognition, recording etc. inputs, this telepilot is used for gathering voice signal, carries out speech recognition.This undoubtedly for voice broadcasting, recording playback, synthesize and distinguish the condition of providing.

In Ling Yang compression algorithm, SACM-A2000, SACM-S480, SACM-S240 are mainly used to playback, also can be used for voice message, and DVR is then used for record/playback.

Speech recognition mainly contains following two kinds:

(1) specific speaker recognition SD(speakerdependent).Refer to that voice model is by single training, also can only the voice command of recognition training people, and other people command recognition efficiency is lower or almost can not identify.

(2) nonspecific speaker recognition SI(speakerindependent).Refer to that voice model is trained by the people of all ages and classes, different sexes, different accent, the order of group can be identified.

Identifying first to consider except input speech signal noise and carry out and increase the weight of to process, promote high fdrequency component, then spectrum analysis is carried out by methods such as linear predictor coefficients, find out the characteristic parameter of voice as unknown pattern, then compare with the mode standard prestored, when the unknown pattern inputted is consistent with the feature of mode standard, just by machine recognition, produce recognition result and export.If input voice and the feature of mode standard completely the same no doubt good, but voice contain uncertain factor, on all four condition does not often exist, in fact nobody can say twice with definitely identical intonation a word, therefore, pre-establish and calculate the input feature mode of voice and the similar degree of each feature mode, or the algorithmic rule of distance degree is solidificated in ROM, this apart from minimum, and most similar pattern is as the means identifying corresponding voice.Certainly, the factor that impact identifies also has, as the different of (or English) and clipped (Chinese) of pronouncing continuously.(the two difference is the aperture time having more than 200ms between word).

(3), speech recognition flow process section

Speech recognition program comprises recognizer and interrupt service routine.Recognizer completes and chooses dictionary, initialization A/D and timer TimerA, identifies computing and recognition result process, and flow process is as section (3.1).A/D transformation result is read in interrupt service routine timing, and stored in buffer zone, the voice signal being input as MIC passage of A/D.Speech recognition and playback time-sharing multiplex TimerAFIQ interrupt, and judge speech recognition and carry out speech processes by zone bit.

System adopts double control menu (soft key and touch-screen), and adopt button, in order to prevent unscheduled event, (inefficacy of touch-screen) occurs, the simulation of hardware section is as follows:

K9F1208 is Large Copacity, the highly reliable flash storage of the employing NAND technology that Samsung company produces.This device memory capacity is 64*8 position, in addition also has the free storage of 2048K*8 position.This device adopts TSSOP48 encapsulation, operating voltage 2.7 ~ 3.6V.

Its method with SPCE061A interface microcontroller: the IOAO^7 of data bus IOO^7 and the SPCE061A of K9F1208 is connected, with the IOBO of single-chip microcomputer as read enable signal (RE), IOB1 is as written allowance signal (WE), IOB2 is as chip selection signal (CS), IOB3 allows signal (ALE) as address latch, and IOB4 latches as order and allows signal (CLE).Because do not need write-protect, native system has received high level write-protect pin (WP).RDY/B signal wire need not, this example is unsettled process, and the state of K9F1208 is operated by ReadStatus and realizes.

Repeatedly travel to and fro between all departments in patient assessment's process, queuing repeatedly, to wait, a large amount of time energy is consumed in non-diagnosis and treatment process.Outpatient Service Flow pattern existing defects is that patient complains inconvenient main cause of seeking medical advice.Patient is a underlying cause in length ineffective time that outpatient service stops, and why long in the outpatient service residence time patient is, to be unfamiliar with and the Outpatient Service Flow of hospital arranges unreasonable relevant with patient to hospital environment.Therefore, formulate corresponding strategy and reproduce Outpatient Service Flow, reduce the residence time of patient in outpatient service.Therefore how patient is directed to place accurately extremely important, therefore external print facility, data such as the letter of the plane of each for hospital section office section, points for attention etc. are preserved inner, guidance can be printed as required, or in hall, place giant-screen undertaken inquiring about (although the method alleviates doctor's burden by patient, but there is the situation that equipment is not enough unavoidably, result in blockage).

The function of the USB device system invented is fairly simple, and it mainly realizes the simple communication between SPCE061A and PC, is that the one of SPCE061A single-chip microcomputer is applied substantially, and system has three kinds of simple functions: 1. detect the whether successful connection of USB peripheral hardware.2., by clicking the button in the application software of PC end, can light or extinguish the LED be connected with SPCE061A single-chip I/O mouth.3. application software sends arbitrary string to SPCE061A, SPCE061A acceptance, loopback character string, when application software receives character string, it can be shown.

The groundwork flow process of system is: PC holds application software, send ID0(to make main frame and equipment can be synchronous, this system definition three shake hands ID:ID0, ID1, ID2.) receive data to PDIUSBD12, PDIUSBD12, produce interrupt notification SPCE061A single-chip microcomputer and read data.If the data that SPCE061A reads are ID0, so send ID0 to PDIUSBD12; After PC end application software sends data, read the data that peripheral hardware sends, if the data read are ID0, so eject a prompting frame, the successful connection of prompting USB peripheral hardware.After this communication between the application software of PC end and USB peripheral hardware is all undertaken by ID.

LED1 lamp is very useful, and it is the GOODLINK pilot lamp of PDIUSBD12, when system enumeration can according to communication situation interval flicker, when PDIUSBD12 enumerated with configuration successful after, will light always.Can glimmer when usb communication subsequently, this is very useful to debugging.

The software systems initialization section of this module single-chip microcomputer end comprises system clock, I/O port, interrupts arranging (opening external interrupt), and PDIUSBD12 chip software resets, initialization.The core of this main flow is the request process of protocol layer, and it is related to PC and enumerates the success or not of USB peripheral hardware.So when debugging Single Chip Microcomputer (SCM) program, the enumeration order of Window to USB device paid special attention to.If enumeration succeeds, main frame will find new equipment, prompting install driver; Otherwise find unknown device, USB peripheral hardware is unavailable.

Its method with SPCE061A interface microcontroller: the IOAO^7 of data bus IOO^7 and the SPCE061A of K9F1208 is connected, with the IOBO of single-chip microcomputer as read enable signal (RE), IOB1 is as written allowance signal (WE), IOB2 is as chip selection signal (CS), IOB3 allows signal (ALE) as address latch, and IOB4 latches as order and allows signal (CLE); Because do not need write-protect, native system has received high level write-protect pin (WP); RDY/B signal wire need not, this example is unsettled process, and the state of K9F1208 is operated by ReadStatus and realizes;

Repeatedly travel to and fro between all departments in patient assessment's process, queuing repeatedly, to wait, a large amount of time energy is consumed in non-diagnosis and treatment process; Outpatient Service Flow pattern existing defects is that patient complains inconvenient main cause of seeking medical advice; Patient is a underlying cause in length ineffective time that outpatient service stops, and why long in the outpatient service residence time patient is, to be unfamiliar with and the Outpatient Service Flow of hospital arranges unreasonable relevant with patient to hospital environment; Therefore, formulate corresponding strategy and reproduce Outpatient Service Flow, reduce the residence time of patient in outpatient service; Therefore how patient is directed to place accurately extremely important, therefore external print facility, data such as the letter of the plane of each for hospital section office section, points for attention etc. are preserved inner, guidance can be printed as required, or in hall, place giant-screen undertaken inquiring about (although the method alleviates doctor's burden by patient, but there is the situation that equipment is not enough unavoidably, result in blockage).

5. the function of invented USB device system is fairly simple, and it mainly realizes the simple communication between SPCE061A and PC, is that the one of SPCE061A single-chip microcomputer is applied substantially, and system has three kinds of simple functions: 1. detect the whether successful connection of USB peripheral hardware; 2., by clicking the button in the application software of PC end, can light or extinguish the LED be connected with SPCE061A single-chip I/O mouth; 3. application software sends arbitrary string to SPCE061A, SPCE061A acceptance, loopback character string, when application software receives character string, it can be shown;

The groundwork flow process of system is: PC holds application software, send ID0(to make main frame and equipment can be synchronous, this system definition three shake hands ID:ID0, ID1, ID2; ) receive data to PDIUSBD12, PDIUSBD12, produce interrupt notification SPCE061A single-chip microcomputer and read data; If the data that SPCE061A reads are ID0, so send ID0 to PDIUSBD12; After PC end application software sends data, read the data that peripheral hardware sends, if the data read are ID0, so eject a prompting frame, the successful connection of prompting USB peripheral hardware; After this communication between the application software of PC end and USB peripheral hardware is all undertaken by ID;

LED1 lamp is very useful, and it is the GOODLINK pilot lamp of PDIUSBD12, when system enumeration can according to communication situation interval flicker, when PDIUSBD12 enumerated with configuration successful after, will light always; Can glimmer when usb communication subsequently, this is very useful to debugging;

The software systems initialization section of this module single-chip microcomputer end comprises system clock, I/O port, interrupts arranging (opening external interrupt), and PDIUSBD12 chip software resets, initialization; The core of this main flow is the request process of protocol layer, and it is related to PC and enumerates the success or not of USB peripheral hardware; So when debugging Single Chip Microcomputer (SCM) program, the enumeration order of Window to USB device paid special attention to; If enumeration succeeds, main frame will find new equipment, prompting install driver; Otherwise find unknown device, USB peripheral hardware is unavailable.
