Problems solved by technology

[0004] The key to digital transformation in industrial applications is the ratio of input to output. If it takes a lot of money and time to carry out wiring transformation and other work, the effect of efficiency improvement or cost saving is not obvious, and it will definitely become a major obstacle to the digital transformation of equipment.

Embodiment 2

[0050] Such as figure 2 As shown, this embodiment provides a Bluetooth communication method for bypass listening, including the following steps:

[0051] 1) Listen to the data transmission of the listened device in real time through the bypass listening mode, and execute step 2) when the data flow is captured;

[0052] 2) Filtering the data stream;

[0053] 3) judging whether the data stream is valid data, if so, then perform step 4), if not, discard the data stream;

[0054] 4) If the data stream is real-time data, real-time data display is performed, and if it is cold data, cold data cache is performed;

[0055] 5) Extracting the transmission data that needs to be transmitted from the data stream, that is, parsing out the required data packets, and encrypting the transmission data;

[0056] 6) Use the non-networking multi-to-many Bluetooth transmission method to realize the transmission of the encrypted transmission data, specifically: fill the encrypted transmission dat...

Abstract

The invention relates to a bypass interception Bluetooth communication device and method and application thereof. The communication device is integrally built in an intercepted device, and comprises:a Bluetooth main chip; an interception interface circuit which is connected with the Bluetooth main chip through a signal conditioning circuit and is in bypass connection with the intercepted device;a Bluetooth antenna, a crystal oscillator circuit and a display circuit which are connected with the Bluetooth main chip; and an isolation power supply used for supplying power to the device. In the communication method, the data transmission condition of the intercepted device is monitored in real time in a bypass monitoring mode, and when a data stream is captured, the data stream is filtered; it is judged whether the data stream is valid data or not; transmission data needing to be transmitted is extracted from the data stream, and the transmission data is encrypted; and the transmission ofthe encrypted transmission data is realized by adopting a networking-free many-to-many Bluetooth transmission mode. Compared with the prior art, the bypass interception Bluetooth communication deviceand method and the application thereof have the advantages of low cost, convenience in use, reliability in transmission and the like.

Description

technical field [0001] The present invention relates to the technical fields of the Internet of Things and wireless communication, and relates to a communication device, in particular to a Bluetooth communication device, method and application thereof for bypass interception. Background technique [0002] With the development of the digital economy, in the industrial and medical industries, there is a large amount of data from existing equipment that needs to be collected and recorded. Whether it is spot checks on industrial sites or ward rounds by doctors in the medical industry, the current main method still relies on the traditional form of paper and pen records, which is time-consuming and error-prone. Therefore, both the industrial and medical fields of digital transformation are developing rapidly, and at the same time, they are facing great challenges. [0003] The current digital transformation method mainly depends on the existing external interfaces of the equipme...
