The invention relates to a one-line bus type ward calling system which belongs to the technical field of calling system. The system comprises a temperature sensor, a memory, a single chip, a display, a voice circuit, a speaker and a power supply, wherein an input end of the memory is connected with the temperature sensor, an output end of the memory is connected with the single chip; an LED display is connected with an output end of the single chip; an input end of the voice circuit is connected with the output end of the single chip; and an output end of the voice circuit is connected with the speaker. The temperature sensor measures temperature; and when fingers are put on the temperature sensor, the temperature sensor senses the temperature value and sends the temperature value to the single chip. The single chip judges the temperature rise on one hand, and sends voice alarm of ward number on the other hand; and the ward number is displayed by the LED display. The one-line bus type ward calling system has the advantages of low maintenance cost, good using effect and the like, and is simple, reliable to use and convenient for the nurses or doctors to see or listen.
Description
Technical field
The present invention relates to one-wire bus formula ward calling system, belong to the calling system technical field.
Background technology
The ward calling system of hospital's use at present; The wired or wireless communication network calling system of main employing; Wired system often need carry out that complicated wiring, wiring expense are higher, easy break-down, inconvenient maintenance; Not only cost is high for wireless system, the communication apparatus electromagnetic interference (EMI) is big to the influence of medical instruments and equipment, and use is complicated, communication effect is unstable.Adopt the ward calling system of one-wire bus formula, can the simplified wiring installation work, effectively reduce cost, uses simple and reliable, but the present bibliographical information of not seeing one-wire bus formula ward calling system as yet.
Summary of the invention
Technical matters to be solved by this invention provides a kind of one-wire bus formula ward calling system, solves defectives such as wiring complicacy, cost height in the ward, has very high practicality.
Technical scheme of the present invention is: this ward calling system; Comprise temperature sensor 1, storer 2, single-chip microcomputer 3, display 4, sound circuit 5, loudspeaker 6 and power supply 7; The end of going into of storer 2 links to each other, goes out end and links to each other with single-chip microcomputer 3 with temperature sensor 1; LED shows that 4 go out end with single-chip microcomputer 3 and link to each other, and sound circuit 5 is gone into end and single-chip microcomputer 3 and gone out end and link to each other, go out to hold and link to each other with loudspeaker 6.
Store 64 ROM codes representing each temperature sensor position in the said single-chip microcomputer 3 in system's single-chip microcomputer; Through the detection determining program is set in advance; The table of comparisons of opening relationships table and sensing station and ward room number between temperature measuring positions point and 64 ROM codes; Thereby confirm the Position Number of each temperature sensor, be implemented in the multipoint temperature measuring system identification a plurality of sensors.
Store the voice messaging of corresponding sick bed label in the said sound circuit 5 in advance, can realize the direct voice reporting of calling out sick bed number.Native system temperature sensor 1, storer 2, single-chip microcomputer 3, light-emitting diode display 4, sound circuit 5 are common commercially available prod; Temperature sensor adopts ordinary numbers temperature sensor (like DS18B20); Storer can adopt normal memory (like AT24C04, LM1420 etc.); Single-chip microcomputer can adopt 8051 single-chip microcomputers, and display can adopt the common LED display.
When the present invention worked, when patient's hand did not touch temperature sensor 1, the environment initial temperature data that system records were stored in the storer 2; Through the program that in single-chip microcomputer, is provided with in advance, when making temperature variation≤1 that temperature sensor records ℃, the temperature value that records once more can not cover the temperature value that recorded last time, and system can not report to the police yet.When patient's hand touches temperature sensor, the temperature that measures than storer 2 in the temperature value of storage when significant change (>=1 ℃) is arranged; System promptly reads the ROM code in the single-chip microcomputer automatically; Through looking into measuring position point and the relation table between 64 ROM codes of temperature sensor in the single-chip microcomputer internal storage; Obtain the Position Number of temperature sensor 1, start audio alert then and on LED display, show bed label.When doctor or nurse get into the ward, touch the DS18B20 temperature sensor once more, system reset, control voice signal and LED signal promptly stop.
The present invention will number corresponding to each temperature sensor of sick bed; Through the measurement of sensor to patient temperature; The temperature variation signal is delivered to 8051 single-chip microcomputers; Look into the relation table between the measuring position point and 64 ROM codes of temperature sensor in the storer by 8051 single-chip microcomputers, can obtain the Position Number of temperature sensor 1, and start audio alert and on LED display, show bed label.Has the wiring of the one-wire bus of employing formula; Carry out data processing through single-chip microcomputer; Control ward bed label demonstration and audio alert, avoided traditional complicated wire laying mode, the reliability of system is increased greatly, reduced the constant and cost increase of use that frequent maintenance brings simultaneously.Have advantages such as installation wiring is simple, use is reliable, maintenance cost is low, result of use good, convenience is seen by nurse or doctor or hear.
Description of drawings
Fig. 1 is the synoptic diagram of ward of the present invention calling system;
Fig. 2 is a ward of the present invention calling system embodiment circuit diagram.
Each label is represented successively among the figure: 1, temperature sensor, 2, storer, 3, single-chip microcomputer, 4, light-emitting diode display, 5, sound circuit, 6, loudspeaker.
Embodiment
Below in conjunction with accompanying drawing and embodiment, the present invention is done further elaboration, but protection scope of the present invention is not limited to said content.
As shown in Figure 1; This one-wire bus formula ward calling system; Comprise that DS18B20 digital temperature sensor 1 (utilizes the parasite power power supply; Can give to be equipped with power supply separately, thereby can better realize long-range thermometric), LM1420 storer 2,8051 single-chip microcomputers 3, common liquid crystals display 4, normal speech integrated circuit 5, loudspeaker 6 and common power 7.The end of going into of storer 2 links to each other, goes out end and links to each other with single-chip microcomputer 3 with temperature sensor 1, LED shows that 4 go out end with single-chip microcomputer 3 and link to each other, and sound circuit 5 is gone into end and gone out to hold with single-chip microcomputer 3 and link to each other, go out to hold and link to each other with loudspeaker 6.Store the voice messaging of corresponding sick bed label in the sound circuit 5 in advance, realize the direct voice reporting of calling out sick bed number.
Native system at first utilizes the inner ROM of 8051 single-chip microcomputers, sets up the mapping table of Position Number and sensor sequence number, has realized in the multipoint temperature measuring system identification to a plurality of sensors, and sets up the table of comparisons of sensing station and room number.When hand does not touch the DS18B20 temperature sensor, the temperature data that records will be stored in the LM1420 storer, if when temperature change does not surpass 1 ℃, the temperature value that records once more can cover the temperature value that recorded last time.When hand touches temperature sensor; The temperature of testing and LM1420 storer raise 1 ℃ and when above; Read the ROM code of DS18B20; The Position Number that can obtain temperature sensor DS18B20 through measuring position point and the relation table of looking in the single-chip microcomputer internal storage between 64 ROM codes of temperature sensor, thus start audio alert and on LED, show bed label.When doctor or nurse get into the ward once more, touch the DS18B20 temperature sensor, voice signal and LED signal stop.
