Problems solved by technology

In addition, due to the different functional requirements or production batches of the plug-in modules 120, there may still be differences in the allowed communication rates even for plug-in modules 120 of the same model.
[0006] At present, the monitoring device 110 with a single hardware configuration is usually difficult to meet the requirements of infrared communication with the plug-in modules 120 with different communication rates, that is, the existing infrared communication method still has the defect that the monitoring device 110 is not compatible with different plug-in modules 120

Embodiment Construction

[0042] Typical embodiments that embody the features and advantages of the present invention will be described in detail in the following description. It should be understood that the present invention is capable of various changes in different embodiments without departing from the scope of the present invention, and that the description and illustrations therein are illustrative in nature and not limiting. this invention.

[0043] As we all know, infrared is an electromagnetic wave with a wavelength between 750nm and 1mm. Its frequency is higher than that of microwaves and lower than that of visible light. It is a kind of light that cannot be seen by human eyes. Since the wavelength of infrared rays is relatively short, the diffraction ability to obstacles is relatively poor, so it is generally used in the scene of one-to-one matching in short-distance wireless communication.

[0044] In existing monitoring devices, such as plug-in monitors, infrared communication technology...

Abstract

The invention discloses an infrared communication method, device and system. The infrared communication method comprises the steps that monitoring equipment detects connection of a plug-in module; if the plug-in module is connected, power is supplied to the plug-in module, and infrared communication is started according to the current communication rate; handshaking with the plug-in module is performed according to the current communication rate, and infrared communication between the monitoring equipment and the plug-in module is established if handshaking is successful; and if handshaking is not successful within the preset period of time, polling is performed on the first communication rate allowed by the work mode supported by the monitoring equipment, and the first communication rate obtained through polling acts as the current communication rate to transmit a handshaking request to the plug-in module until the plug-in module responds to the handshaking request. The requirement of infrared communication compatibility can be met. According to the infrared communication method, device and system, the communication rate can be adaptively adjusted.

Description

technical field [0001] The present invention relates to the technical field of communication applications, in particular to an infrared communication method, device and system. Background technique [0002] figure 1 It is a schematic diagram of the application environment of the infrared communication method. Such as figure 1 As shown, the application environment includes a monitoring device 110 and a plug-in module 120 . [0003] Among them, the monitoring device 110 is a device for measuring and controlling physiological parameters of the human body, which can be compared with known set values, and an alarm can be issued if it exceeds the standard. According to the structure, the monitoring device 110 can be classified into: portable monitors, plug-in monitors, telemetry monitors, ECG monitors and so on. The plug-in module 120 is a plug-in monitor used in the monitoring device 110 . [0004] If the working modes supported by the monitoring device 110 and the plug-in m...
