The wireless module transmits data wirelessly, which is easier to maintain than wired communication. The module will go through multiple processes during the production process.
SAE J1939 (hereinafter referred to as J1939) is the recommended standard of the American Society of Automotive Engineers (SAE). digital communication between electronic components.
A radio frequency connector is a radio frequency coaxial connector, which is usually regarded as a component attached to a cable or installed on an instrument as a component for electrical connection or separation of transmission lines.
Auto-ACK and ReSend are long-talked-about issues in our wireless communication. After the data is radiated into the air through the modulation circuit, how to judge whether the other party has received the data? If not received, what mechanism will be used to handle this exception?
At present, most researches focus on how to integrate the information obtained by multiple LoRaWAN gateways to improve network scalability and decoding rate, and less research on the gateway itself. How to optimize the layout of one or more gateways so that each gateway can play the most role in a specific application is also an issue that needs to be discussed.
The inductive sensor is a device that uses the law of electromagnetic induction to realize non-electrical measurement through the change of the self-inductance and mutual inductance of the coil. It is characterized by the use of the physical characteristics of the inductance, which can measure displacement, vibration, pressure, flow and other signals without direct contact with the measured object.
Entering 2022, IoT technology is becoming more and more popular in all walks of life. LPWAN technology (low-power wide area network, long-distance IoT wireless communication technology) relies on wide signal coverage, small occupied bandwidth, large number of terminal connections, and low power consumption. , low cost and other advantages, to win a high penetration rate in the global market.
RSSI (Received Signal Strength Indication)——The received data signal strength indication, as an optional part in the wireless data transmission layer, is used to determine whether the quality of the transmission link is reliable and whether to increase the strength of broadcast data transmission.
IIoT (Industrial Internet of Things) is the abbreviation of Industrial Internet of Things. It integrates various acquisition and control sensors or controllers with sensing and monitoring capabilities, as well as mobile communication, intelligent analysis and other technologies into all aspects of the industrial production process. Significantly improve manufacturing efficiency, improve product quality, reduce product cost and resource consumption, and ultimately realize the promotion of traditional industries to a new stage of intelligence.
