Embodiment Construction

[0012] The present invention will be further described below in conjunction with the accompanying drawings and embodiments, but the protection scope of the present invention is not limited to the content described.

[0013] Such as figure 1 As shown, the first-line bus-type ward call system includes DS18B20 digital temperature sensor 1 (powered by parasitic power supply, it is not necessary to provide a separate power supply, so as to better realize remote temperature measurement), LM1420 memory 2, 8051 single-chip microcomputer 3, ordinary Liquid crystal display 4, common speech integrated circuit 5, loudspeaker 6 and common power supply 7. The input end of the memory 2 is connected with the temperature sensor 1, and the output end is connected with the single-chip microcomputer 3; The voice information of the corresponding hospital bed number is pre-stored in the voice circuit 5, so as to realize the direct voice reporting to the calling hospital bed.

[0014] This system ...

Abstract

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 [0001] The invention relates to a one-line bus type ward calling system, belonging to the technical field of calling systems. Background technique [0002] At present, the ward call system used in hospitals mainly adopts wired or wireless communication network call system. The wired system often requires complex wiring, high wiring costs, prone to failure, and inconvenient maintenance. The wireless system is not only expensive, but the electromagnetic interference of communication equipment is harmful The impact of medical instruments and equipment is large, and the use is complicated and the communication effect is unstable. The use of the first-line bus type ward call system can simplify the wiring installation project, effectively reduce the cost, and is simple and reliable to use, but there is no literature report on the first-line bus type ward call system. Contents of the invention [0003] The technical problem to be solved by the present invention ...
