Detailed Description
The following non-limiting examples are presented to enable those of ordinary skill in the art to more fully understand the present invention and are not intended to limit the invention in any way.
The invention is described in detail below with reference to the figures and the specific examples.
As shown in fig. 1, the intelligent medical monitoring device based on wireless optical sensor network includes: the system comprises a user terminal 1, an indoor access terminal 2 and a server terminal 3.
Referring to fig. 2-3, fig. 2 is a schematic structural diagram of a micro device of a user terminal 1, which includes a sensor module 4, an infrared light transmitting module 5, a visible light receiving module 6, and a processor 7. The sensor module 4 comprises pluggable sensors, such as: blood pressure sensor, body temperature sensor, heart rate sensor. These sensors can acquire physiological parameters of the user in real time. Between the user terminal 1 and the indoor access terminal 2, the infrared light is used as an uplink, and the visible light is used as a downlink. In the user terminal 1, the infrared light transmitting module 5 encodes and modulates the uplink signal 10 according to an infrared communication protocol, and then transmits the uplink signal 10 by using infrared light as a carrier under a driving circuit. The visible light receiving module 6 is used for identifying the downlink signal 11 sent by the access base station. The processor 7 is a main body module of the user terminal, which is used for processing information of the user terminal and supporting a small-capacity local cache to protect important data of the sensor.
As shown in fig. 3, the indoor access terminal 2 is a relay for data interaction between the user terminal 1 and the server terminal 3, and the visible light transmitting module 8 and the infrared light receiving module 9 are respectively responsible for downlink transmission and uplink reception with the user terminal. The visible light transmitting module 8 encodes and modulates the downlink signal 11, and then loads the downlink signal 11 onto the LED visible light by driving the brightness variation of the LED lighting device. The types of downlink signals 11 can be divided into unicast and broadcast. The background server terminal 3 sends information including person searching, medication reminding and the like to a specific user in a unicast mode; and sending the notice to all users under the system in a broadcast mode. The infrared light receiving module also follows the infrared communication protocol. The indoor access base station 2 and the server terminal system 3 are connected by a standard ethernet interface.
The indoor access terminal 2 is not only responsible for data interaction relay, but also responsible for indoor positioning based on visible light. The lighting area of the indoor LED lighting device is limited, and the lighting areas of different lighting devices are overlapped. But at the same illumination intensity of the lighting device, receiving a stronger visible light signal indicates that the user is closer to the lighting device. The indoor positioning of visible light according to the invention is based on this principle. Firstly, a background service system is pre-assigned with a specific ID number according to the position information when an access base station is built. The indoor access base station will periodically transmit broadcast signal, and its data frame contains the ID number. The successful parsing of the data frame by the user terminal indicates that the user is currently located near the base station. Even if a plurality of base stations send broadcast signals at the same time, the user terminal can only analyze the signal with the maximum light intensity as the base station to which the user terminal belongs.
The server terminal 3 is an upper computer software, and is connected with all the indoor access base stations 2 through Ethernet ports. The software contains a database, and the database collected from the user terminal is stored in the software for inquiry or deep utilization. Medical care personnel can conveniently and quickly inquire the heart rate, position and other information of a certain patient through software; sending information including person seeking, medication reminding and the like to a specific user in a unicast mode; and sending the notice to all users under the system in a broadcast mode. Once physiological information of a certain patient is abnormal on a display of the server terminal 3, an alarm signal can be rapidly sent out to inform a guardian to arrive at the patient according to the positioning information, and the server terminal has important value for emergency treatment and life safety of the patient.
Fig. 4 is an overall schematic diagram of a wearable smart medical system based on a wireless optical sensor network technology. The user can wear wearable user terminal 1 in shoulder or wrist department, inserts server terminal 3 through indoor access end 2 to show user information on the display, medical personnel can conveniently inquire information such as patient's rhythm of the heart, position.
The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art should be able to cover the technical solutions and the inventive concepts of the present invention within the technical scope of the present invention.
